content: Back in the days of Walkmans and cordless phones, many electric gadgets have compartments for AA or AAA batteries. Users can even use rechargeables. Life of the device is not tied to the battery. Nowadays, many devices are embedded Li-ion (Macs?). Do consumers really prefer that? I understand it's easy to charge a device by just plugging a USB, but that's fine for something like a phone where it'll be obsolete in a few years and needs frequent charging. But still, lots of devices can last much longer than that and don't get obsolete. Furthermore, it's nice to be able to swap in a fresh battery when you need it rather than wait for it to finish charging.Thoughts?

content: I have an iPhone and an iPad, both have no user accessibility to the batteries. Now, I have replaced the battery on several of my iPhones, not too hard but the average unskilled person might not be able to do it. The iPad ... ridiculous to get to the battery, but I could do it if I wanted to. The average person wouldn't even try.Why do they do this? I don't know if it's the sheer amount of energy the battery has stored which they might think is dangerous, or it's that they want money for repairs.I'll let others chime in on that.

content: You can still find devices with replaceable battery packs, just not from Apple. Their model for "need it now" is the external battery pack. The last apple product I owned was the apple II, so that hasn't been much of a problem for me.Uninstalled lithium batteries can be a travel problem at airports. The FAA doesn't allow them in checked bags at all, and are limited in quantity in carryon bags. Airline policies may be even more restrictive than that.

content: The reason I replaced my first four mobile phones (one each from Nokia, Ericsson, Siemens, and Vodafone(Sharp) was that after two or three years the battery connection became unreliable. I've never made or received a lot of phone calls -- a couple a week maybe -- and in the days before internet-connected smartphones there was no reason to take the phone out of your pocket unless it rang or you wanted to make a call yourself. Batteries only needed recharging once in a week or ten days (the same applies to iPhones, by the way, if you leave them in your pocket and don't constantly use them).I'd get a new phone and all would be well for a couple of years. And then people would start to complain that they couldn't call me. I'd take the phone out of my pocket and discover that it was off. I'd turn it on and .. hey .. nearly full battery. Back in the pocket and a day later notice that it had turned itself off again.I tried cleaning contacts, bending contacts, wedging something to make the battery press tighter, a new battery pack. Once the problem started, nothing except a new phone would cure it.Then in late 2007 I got an iPhone with soldered in battery and I've never had that problem again. MUCH MUCH BETTER.Of course after five years or whatever the battery gets tired and needs replacing. And Apple sells replacement batteries and the price includes opening the device, unsoldering the old battery, and soldering in the new one.At least in the case of laptops, replacing the soldered-in batteries in the unibody machines is the same price as simply buying a new battery for the older machines with user-replaceable batteries. The labour to do it is "free". In fact it probably costs them less to make the internal batteries anyway.

content: Two words: planned obolescence.Sometimes it's hand-waved away with an excuse. One example of this is electric toothbrushes "need to be waterproof", but that's no reason to make them completely unserviceable --- plenty of other devices, like torches, can be waterproof while also having replaceable batteries. In fact I haven't come across one that's threaded together like a torch, despite that being the obvious way to design one for ease of service. (And likewise, I'm surprised that no one seems to have thought of making an electric toothbrush head that can be interchanged with a torch head...)In the case of Apple's phones, the excuse has been that they wouldn't be as thin, or that a phone with a metal casing can't have a replaceable battery; the Chineseproved them wrong.

content: I hate non-accessible batteries also. However two of their arguments hold SOME water..1. Devices are so thin these days, there are no generic cells or batteries that will fit them anymore. Note that cell phones with removable/replaceable batteries each have their own proprietary battery not interchangeable with any other brand (or even model)2. It is more "green" to force users to keep recharging the internal battery instead of offering the opportunity for them to use one-time primary (non-rechargeable) cells which then go into the landfill.I'm not saying that I like either of these arguments. Especially for professional video and audio production gear, I don't want to be stuck somewhere with no charged batteries left in an expensive situation. I want the ability to use AA or C or D cells in a critical situation.

content: I actually have a severe dislike for standard cell batteries. For anything with any real power, you blow half your money on either a completely unreasonable amount of cells, or buy expensive rechargable batteries that barely last.However, I don't see the problem here. Every battery is replaceable, even if it says it's not. It's just a matter of reverse construction utilizing percussive maintenance.I do like the idea of replaceable electric car batteries, so you can just have a charging dock where you can throw batteries, and have a few sets on tap for whenever you need it.To be honest, all batteries suck. I'm excited for the day when decent batteries are a thing.

I mean people that don't understand electronics and don't want to try doing it themselves.In the other hand, the mobile I'm writing on just now is 3.5 years old and its user replaceable battery is not in best condition but lasts a day, just fine. It may last almost two days when new, but still fine after this time.So, I mean that it's possible to dessign a battery that lasts device practical life in most of user cases.Enviado desde mi Jolla mediante Tapatalk

However, if I design it in such a way that you are forced to use services I provide for repairs, at a much higher markup, then I not only make money on the original sale, but all repairs. Add to that multiple upgraded versions within the life of the widget, all of which are slightly more than the repairs and I have you and your pocketbook by the balls.

content: I would say cost reduction, size and weight reduction and a large increase in warranty lifetime reliability.To have a removable battery it needs to be in its own housing that has to be strong enough that the average person cannot bend it in there pocket and have it internally short out (shots fired :p) equally there generally needs to be a recessed connector so that even thrown in a pocket with keys its unlikely to be shorted. both of these add to costs and weight, though they do make failures from the cell less eruptive as the shell the cell is in can better contain the energy of a violent short.Next up is reliability, look at a beginners project on a breadboard to a more experienced designer, they will migrate to short to mid term reliability, and only go to long term when it doesnt cost them extra in time or money, Battery contacts are a failure mode, and the spring contacts once dirty or bent are generally very hard to repair as they are at the end of a thin long battery compartment.A battery compartment unless properly sealed is also a direct route for water to reach the battery terminals should it be left out in the rain, or dropped in water. this is also partly where some of the wireless charging technologies came in to play, as its much easier to fully seal a device from water if you have no openings. I personally have lost 2 waterproof cameras to a salt grain that collected along the edge of the gasket. despite being cleaned very well before and after dives. eventually some piece of crud collects and the outside world gets in.Now a non removable battery is different from a non serviceable battery, this is where i call cost cutting gone mad. So far the 2 handheld tools i have built used a usb charging lipo for cost and simplicity, mounted inside an alu extrusion with screwed on covers. now that battery cannot be easily replaced without tools, but it can be serviced, with the cover removed you can access it and replace it. and it uses commonly available tools, and the battery connects via a short flylead and connectorMany GPS's follow a similar structure, you pop some phillips screws and there is a lipo with a connector.Phones however are hard for this method, as now the screens are seamless to the bezel meaning you more or less forced to make all access through the back, while keeping the phone mechanically strong. samsung did this well on the SG5, where the cover and gasket clip on in a really thin way, and the gasket the part that wears is on the removable part, but if you where swapping batteries each day, it would not last long, i would assume the plastic clips would be only good for a few thousand cycles at most.

And most of them had half to two thirds of original battery capacity. I mean real capacity, not BS that was written on them. Remaining OKayish batteries were not any better than original ones either. Of course there was a way to increase capacity as some idiots put a thicker battery and then battery cover looked egg shaped with huge gaps underneath.

content: In some cases, by removing the battery lid (cover) and making the battery internal there are some benefitsYou may get slightly higher capacity battery because the space that was previously used for springs (battery contacts) or plastic walls to prevent leakage from alkaline batteries from attacking the boards can now be used for larger battery (or they could use flatter and thinner batteries)By using lipo or other styles of batteries, they can do lightweight products compared to AA or AAA batteries that are heavier (and have metal case)They may be able to do a cheaper plastic mold or they may be able to do cheaper aluminum (or zinc or whatever is used for lightweight cases) back covers which in turn would help with heat dissipation and may add rigidity to the product (for example in case of laptops)By not having battery compartments, they may not have to worry about humidity and water ingress through the battery compartment (and they don't have to use rubber seals or use conformal coating or put sealant around battery compartment)

content: I don't know why everyone says that planned obsolescence is the reason. It is clearly physically impossible to design a top tier phone incorporating a user openable battery compartment without making it thicker or reducing battery life. If people really wanted replaceable batteries then there would be more phones with them. People just don't want the trade offs. Regarding obsolescence, there are plenty of other ways a phone goes obsolete without deliberately sabotaging the battery in a phone design. Pointing to some grand conspiracy here is unnecessary.

content: I don't believe in conspiracies, so I dismiss the whole "planned obsolescence" and customer lock-in arguments.Here are somerationalreasons for moving to built-in batteries:Most customers never replaced removable batteries anyway. Long before smartphones were even remotely popular, most people replaced their phones after only 18 months on average. At that age, very few batteries have failed.Size. People like thin. Removable batteries require both the added volume of a battery compartment, as well as the added volume of the shell of the battery needed for safety.Safety. In popular phones with removable batteries (like many Samsung models until recently), battery counterfeiting is rampant. But with Li-Ion/LiPo/etc batteries being so sensitive, those fake batteries can be dangerous. Using internal batteries significantly reduces the chances of a user receiving a counterfeit battery. (Note that I'm not referring to quality aftermarket batteries, but actual fake "original" ones sold to people who believe they are buying the real thing. A normal user has no way to detect a potentially deadly counterfeit battery.Quote from: Lord of nothing on July 21, 2017, 02:19:18 pmIn English, we do not use the word "akku". (We used to use "accumulator", but that is absolutely archaic.) It's arechargeable battery. In common usage, we also call individual cells "batteries", though that is technically incorrect.

Essentially, a user replaceable battery has about 25% less capacity than one that's integrated into the product. That's because you need to have a molded case and contacts for the battery, plus a reinforced structure for it to mate with in the product. That extra space could be used for more battery!In fact, on laptops that use external packs containing 18650 cells, that number increases from 25% to as much as 50%!Apple used to have battery compartments on all their laptops, but changed to custom internal LiPo cells about 6 or 7 years ago. In most cases they're still easy to replace. You simple remove a few screws on the bottom, pop the cover off, unplug the battery, remove a few more screws and it'll pop right out. There are a number of companies that sell aftermarket replacements. Alternatively, Apple will replace it for you for a flat $100 (including service and the battery).As for phones, that's all about using custom molded LiPo pouches to get the maximum capacity in the smallest package. It's that simple. There's no big conspiracy.

content: I am not a big fan of the "thinner at any cost" trend in cell phones, but a user replaceable battery is about the least important factor to me. I carry my phone in my pocket and use it extensively every day. If you can remove a battery compartment I am not going to open for 2 years and make it better in any measurable way -- smaller, lighter, more rugged, better ingress protection, longer battery, more features, or really anything, that is absolutely what I want. Cell phone designs are *insanely* constrained. Manufacturers didn't switch from micro to nano SIM cards for their health. They did it because that tiny sliver of plastic was wasting space that they could use for features their customers cared about.Yes, it does generate extra waste. But take a look at how much trash you put out on the curb every week. Now think what fraction a 150 gram phone adds to that, even if you replaced it every year. Electronic waste is more hazardous than most household waste, and arguably generates more manufacturing waste than other products, but there is no way that my phone is a material part of the waste I generate directly or indirectly. And when you look at the utility I get from a smartphone, it is about the last place to look to reduce environmental impact. Other people's priorities may be different and that is fine, but I think my experience here is pretty typical of flagship / premium smartphone customers. Last I checked there are still plenty of low end phones with replaceable batteries.For other products the calculus changes somewhat. Laptops are bigger, I use them less, they stay current longer, and their design constraints are tight but not as brutal as phones. I find non-replacable batteries in laptops annoying, but I still understand the reasoning. By eliminating the battery bay, you make the chassis stiffer and stronger for the same weight, you save weight and space, and you have more design freedom in placing the battery. In most cases, laptop batteries can be replaced at a service center. Its expensive compared to buying an off brand battery from amazon and swapping it yourself, but it is still quite a bit cheaper than a new laptop. To me, this is a totally reasonable compromise.

The point is, how thin would thesamedevice be with and without a user-replaceable battery. How does it affect total volume, component layout, etc? It is unquestionable that adding the protective elements of a user-replaceable battery (the battery's own shell, barriers in the battery compartment, more robust connectors, etc) add volume, and that volume has to go somewhere.Quote from: CJay on July 23, 2017, 09:52:56 amI specifically addressed off-brand batteries as being outside the scope of my argument. I am talking aboutcounterfeits, which were a huge problem for Samsung. People were spending full price for a battery they believed to be an original Samsung, and instead were receiving a cheap knockoff. This was especially problematic with Amazon, which pools its own stock with that sent in by FBA vendors, who pollute Amazon's legitimate Samsung stock with counterfeits.I also specifically chose my wording to say that non-accessible batteriesreducethe risk of counterfeits, noteliminateit. I never claimed it eliminated the risk entirely.As for your claim that I'm advocating a ban on opening your own goods, I'm sorry, I said nothing of the sort and have no interest in engaging in a childish reductio-ad-absurdum bicker with you.Quote from: CJay on July 23, 2017, 09:52:56 am"Planned obsolescence" means designing a product to failon purposeafter a given amount of time. I have only ever heard of one legitimate instance of this being done, namely the incandescent light bulb cartel of the early 20th century.What we see all the time now is products being designed down to cost, with components selected such as to be as cheap as possible and still outlast the expected lifespan of the device (at minimum, the warranty period). It's a subtle distinction, but it's a difference nonetheless. Why spend more on components that last longer than the device will be used anyway? As I said, even before smartphones, people were switching phones every 18 months on average, almost all still fully functional. Why spend extra on -- and make the consumer pay for -- components that last 5 years instead of 2, if the last 3 of those 5 years will be spent in a drawer or landfill anyway?Why design a smartphone to last 5 years? By that age, it's hopelessly outdated as far as software is concerned.

If you have custom engraving your replacement will take 3 times longer because of this, apples service mentions this is particular. So yeah easier for them, harder for you, but still not a conspiracy.And yeah planned obsolescence is not a money making scheme, it is to make sure no parts are over designed to outlast the others, thereby saving costs. With lithium batteries outlasting the 2-3 year phone cycle, making them removable became part of that it seems.

Because comparing two completely different phones doesn't make sense. Getting rid of the battery compartment definitely enables either a thinner device or more features or more battery capacity in the same size.For sure non-removable are worse for the people who carried extra batteries around. A portable Li-Ion pack is much less convenient than swapping batteries. But in my experience that is a very small market, and even a lot of people who might do that would rather have a better phone and carry an external pack, including (apparently) yourself, since you can still get phones with removable batteries yet you have a pixel.

content: Quote from: ejeffrey on July 23, 2017, 05:47:32 pmNope, I'm not claiming it doesn't take space, I highlighted the difference between the two to show it *CAN* be done in a thin form factor, I realise that it's not an ideal comparison but there is no sealed, thinner S5 or a fatter Pixel with a removable battery so it's not an easy comparison to make.Portable LiIon packs have another significant disadvantage over a removable cell, they can only charge at the rate set by the phone and their own DC-DC, I.E. not that fast and often not fast enough.TBH the Samsung is slightly too thin for my tastes but it's a company provided phone and it does the job it is provided for and is ideal for those times when working the small hours in some back end of nowhere facility where the *only* option is a spare cell or LiIon pack (and as mentioned above, LiIon packs are not ideal)The Pixel and the HTC One before it is my personal phone, it's not as critical that it's always on* so the removable cell was less of a consideration but if they were available I'd have definitely given it consideration.*(and my job has changed so an always on work phone is no longer essential outside of office hours)

content: Quote from: tooki on July 23, 2017, 02:39:36 pmOK, so persuade Samsung to make a version of the S5 without a removable cell or HTC/Google to build a Pixel with and then we can compare properly (somewhat tongue in cheek).My point was that it is entirely possible to produce pretty and slim devices with removable cells, not that they were equivalent devices in any other respect. I appreciate that it will by necessity add an amount of volume and weight, but I chose that example to illustrate that it need not add excessive amounts (and also because they are the two phones I have personal experience of).Quote from: tooki on July 23, 2017, 02:39:36 pmAnd there are, still, batteries out there claiming to be OEM, or at least misleadingly packaged without actually stating such, for devices that are intended to be fitted by end users, it's difficult to discern a genuine battery from an 'off brand' device, especially when the sealed in battery has only in house markings, it may even be reasonable to make an argument that it's easier to offer non original batteries as genuine because the internal ones have less easily identifiable security measures like holograms, serial numbers etc. so the logical extension of that would be to restrict users ability to replace them even further or is that another absurd argument?I'm not saying counterfeiting isn't a valid concern, it very much is and should be stopped for several reasons, not least safety, it's been a big problem for a long time, but claiming sealed in batteries are used because 'it's for your own good' is rather patronising.Quote from: tooki on July 23, 2017, 02:39:36 pmMea culpa, ban was too strong a word but it's easy to think and hard to counter that reducing user serviceability isn't comparable to a restriction of rights or is that absurd too?We've also had this conversation before about Apple error #53 which was 'to protect users' by turning their phone into a useless lump of metal which required, at first, a replacement device to be purchased at significant expense instead of just warning and switching off a facility on the phone.A 'mistake' that was corrected by Apple when a not insignificant number of users got bitten by it.Quote from: tooki on July 23, 2017, 02:39:36 pmIt's hairsplitting IMHO because even on cheap devices often the only component that fails close to the warranty expiry is the battery. It's difficult to make a convincing argument that it's not a form of obsolescence on a sealed device because the device would in all probability be perfectly functional with a new battery and, as you say, expected lifespan is designed in by choice of that (and possibly other) component.It would also be a very short sighted company that couldn't see that as a factor in forecasting future markets.Quote from: tooki on July 23, 2017, 02:39:36 pmI agree, but it's likely given the reliability of electronic components that device will end up in E-Waste because the battery is not user replaceable.It's not a great stretch of the imagination to think that those devices might easily fulfil a useful life in some part of the world with a developing economy, as a device for a child or even as a spare for the time when you need to order a replacement battery for your other device.I would for instance have given my HTC One to my son or be still using it myself if replacing the battery didn't necessitate breaking the phone apart.Of course I had more than one feature on my list of requirements when I made my decision to buy a device with a non replaceable battery, I would have preferred a version with a battery/cell/accumulator that I could easily replace, even if it meant disassembling the phone with some oddball screwdriver, I chose a 'high end' device precisely because I wanted it to last longer, in the event battery life was what necessitated its replacement, not software, but again I realise I may be atypical.

content: I can't speak to how other manufacturers handle it, but Apple performs battery service at a reasonable cost (in the case of laptops, Apple's battery service, including labor, costs exactly the same as the replacement batteries for models with user-replaceable batteries).Since most users will take a device to an official dealer for service, having the batteries be dealer-replacedsignificantly(nearly entirely) reduces the risk of it being a fake. (Conversely, taking it to an aftermarket repair shop almost guarantees it won't be OEM.) Given the consequences of a failed fake battery - like the severe burns that have happened to Samsung users with fake batteries - I absolutely think that taking measures to reduce aftermarket batteries is sensible. The average user is not like us, able to (maybe) tell apart a fake from original, or good quality aftermarket from low quality. It's not about protecting engineer types like us. It's about protecting our family and friends who arenottech wizards. And yes, in this instance, because it's a safety issue, I would actually endorse DRM or similar to enforce use of original parts only, even if it does raise cost. Lithium rechargeables are simply too dangerous to fuck around with.Given that youagreethat it's a safety issue, I'm not sure how you arrive at it being "patronising".As for what fails first on phones, I guess we've had different experiences. I've had the battery fail on some, on others it's been other parts, like switches or buttons. I don't think we can generalize unless we actually have some data on this.As for handing down gadgets, if the person receiving my old iPhone wants a new battery, they can spend the $79 to have the battery service done. (Which is often accomplished by Apple doing a straight device swap, such that any other problems are eliminated as well.)

content: Everyone keeps mentioning planned obsolescence as a bad thing. But if devices were to last 20 years, you'd still be using them right now. Remember 10 years ago?Giving these high tech products a shorter lifespan allowed the market to innovate from the phones below, to black rectangles with a screen containing more mips than a high end pc of 10 years ago.Wait for Moore's law to settle down, forcing innovation to move to the software division to still gain the speed boost everyone is addicted to.Devices just aren't intended to have a replacable battery. And they don't need them in the planned lifespan.It's like replacing the engine in a car, not needed until broken.You can rant on this whatever you want, everything is still going forward technologically. Which is better as standing still.

content: Apple are along the right lines with their battery service which, as you say, ensures users get a reliable, safe product, I'm not sure other manufacturers offer such a service.Sadly there are many more small shops and online stores offering cheaper services which as you say almost definitely guarantees a non OEM battery of varying quality and safety so making it simpler, cheaper to obtain and fit a *genuine* battery would make it safer still wouldn't it?I've no idea (and I suspect Apple could only make a rough guess) what proportion of battery replacements are done by those independent stores with non OEM parts but gut feeling would be that it's a larger number than Apple see, I can walk to five stores (and those are the ones I can think of) in my local small town centre who offer that service while you wait so there is a market for it, obviously I have no idea of volumes for the service but...I believe the answer to the safety problem in this instance is not to make the batteries harder to replace, it's to make it simpler and cheaper to obtain and replace with the genuine article.Because it's a safety critical part I agree that DRM on batteries could be a good thing, I think it may even be a best case scenario with some form of online validation on or before first power up to marry the battery to the phone so the DRM chip can't be cloned or defeated?Of the phones I have experience of (and phones I know of owned by family and friends) the battery is by far the most common hardware failure, other than physical damage to charge/data sockets and smashed screens (leading to my experience of #53).I've had one smartphone die of a genuine component failure attributable to wear, the power switch on a HTC Desire lost its click but still worked and continues to work with a little patience, I had more hardware failures on the fabled old GSM Nokia phones so my personal experience is that phones have become more reliable despite them being designed to a price point.

content: I can relate to what Jeroen3 is saying. As long as the battery outlives the technology era it's fine.In my HTC Desire I replaced my battery after 3 years of owning the device. Once I had done that, within 3 months support for many software applications (eg Skype) dropped.. It basically only purpose remaining was calls, texts andveryslow internet browsing. So much for lengthening the life of a device.At this moment I own a Motorola Moto G 1st gen. I've got the phone for about 34 months and it basically can do what I want; but the device is slow, there is not enough memory left for applications, and worst of all it starts to randomly reset and sometimes not power on. Temporary fix: disconnect battery for 10 minutes and try again. But is the battery at fault? I don't give it a chance: battery life has not changed rapidly and is still OK, and resets occur at 30% charge but also on almost full charge. My conclusion is a faulty main board.So once more I need to replace a phone after 3 years. If it was not this hardware fault, it would probably have been the unusable software in short time. It takes literally a minute to go from homescreen to the keyboard in Google Maps to start navigation. Then if I use the device as a car stereo it becomes twice as bad.So I don't really take planned obsolescence on a phone. My phone has 1GB of RAM, the next one I will be buying has atleast 4GB. FLASH storage is about 20-50x faster with new models. No wonder the phone is slow. Technology in mobile market still moves very quick. It has little use to replace old batteries in that regard.

content: Quote from: CJay on July 25, 2017, 06:17:06 amYep! One of the problems with Apple is that they don't sell spare parts to independent repair shops. So the repair shops are forced to buy spares from China and hope the parts are ok-ish. Or they have to take the spares from broken products. To make things worse Apple's e-waste recycler have to shredder everything. Very "green".Quote from: CJay on July 25, 2017, 06:17:06 amI disagree with that. DRM would make spare batteries more expensive and also would create another vendor lock-in. I know, it's a mess. A few days ago I was looking for a spare battery pack for my ThinkPad. The genuine spare is €115, the cheapest compatible spare €15. Reviews of the cheap spares are mostly something like "after recharging 3 times the runtime went down to 50%". I think I'll choose one around €35 claiming to have Panasonic/Sanyo cells and buy that from a German seller, because he is liable for that claim. And I could replace the cells in the old battery pack with genuine Sony/LG/Panasonic/Sanyo as alternative solution if the spare sucks.

content: Quote from: madires on July 25, 2017, 10:20:22 amIt is a rip off and a vendor lock in is a massive downside but I can't think of another way to make it safe that doesn't involve having to buy a new device.Apple do a good thing with the Battery service, at least it looks that way until you look at the prices properly, it becomes eye wateringly expensive and makes it look very attractive to buy a knock off battery.
