Thread updated to include what must be the most entertaining cell I've tested. Clearly, they spent my money manufacturing their packaging material, instead of manufacturing a better cell. Claimed 2200, tested 1250. The packaging was complete with metallic gold lettering and a semi working hologram (there's something there, I just can't tell what it is). The packaging was so wonderful that I needed to share ;)

I thought I did, but then something very strange happened to me today. I received a second, almost identical (to the fantastic $3.50 el cheapo) cell, in the mail today. There was store branding on the envelope that I didn't recognize, and a reference to leaving positive feedback on eBay. However, there was nothing in the packaging that allowed me to figure out which eBay seller today's cell came from, and I didn't actually order two of the same cell.

What this means, is that seller of one of the unique cells that I'm still waiting for must have substituted this generic cell in, instead of sending me the one pictured in the auction. That's always annoying, but it actually creates a bit of frustration here, because this now makes it difficult for me to identify which of two potential sellers, the good cell came from. So I'm hoping one of two things happens:

1) Today's nearly identical cell is on the testing rig now. If it proves to be a good value also, then I won't really need to pinpoint which of the two sellers each nearly identical cell came from whom.

2) I may be able to figure it out based on questions that I've sent to the remaining sellers that I'm still waiting for cells from. I kept today's envelope, and I've asked each of them whether this package was theirs or not.

seems like a really good deal!! looks like anker is getting popular enough to have their color scheme cloned
[HTC Sensation] D-SHEL:
Thank you so much for this useful information! :)

Look at this. Maybe interesting battery.
[HTC Sensation] Rusty!:
Not a chance in hell of that being what it claims.
[HTC Sensation] Berky99:
Thank you for a proper scientific test.

I don't know why people have thought their subjective non-scientific 'reviews' of batteries have been of much use when they haven't been!

I can appreciate why the poster hasn't and probably won't review Mugen; for the price we know straight away they won't win any prizes compared to the competition here.

To the poster: for your needs, considered a portable solar charger or one of those extended 'back cover' batteries?

Also, do any of these batteries come with plastic cases to keep them? I want some spares but would rather there was no possibility they might short circuit or get stabbed in my bag! Something like this but obviously the right dimensions: http://www.ebay.co.uk/itm/UK-5-x-Ha...21015400601?pt=UK_Storage&hash=item33758b6099
[HTC Sensation] ziddey:
I'm sure it wouldn't be too hard to find some sort of container with accommodating dimensions. Hell, I've punctured a bunch of cell phone batteries because they were in my back pocket. Not sure why my asscheek is still intact. :confused:

I'm getting a Laza 3460mAh battery in the mail that I hope to do some crude testing on: http://www.amazon.com/Laza-Zcell-3460mah-Extended-Battery/dp/B006OS8L0S/ref=sr_1_1

I don't have a means to track Ah, so I'd only be able to provide a time until say 3.2v under 10ohm load. I'm assuming voltage does not scale perfectly linearly with charge?

edit: warning, I did not do my due diligence before buying this battery. While the standard batteries are the same between the Sensation and the EVO 3D, it goes on facing the other direction in the EVO 3D. Because of this, a double battery for the EVO 3D will not work on the Sensation.
[HTC Sensation] rhd-android:
Alrighty, new cell is up tonight. The "Business Edition", claimed 2800mAh, reality of 1300mAh.

One interesting observation / update:

The wonderful generic clone #2 (the one that hit 1710 for $3.45), does NOT fit in the EVO 3D. I thought all cells would be interchangable, but this cell is just ever so slightly thicker. The difference is enough to cause the cell not to fit under the tiny outdented "lip" of the EVO 3D's second camera. So apparently this is a Sensation-only cell. My apologies if anyone ran out and purchased one for their EVO 3D.

Alright, going to address a bunch of comments at once here:

D-SHEL:

Thanks for the link to this cell. I had a self-imposed spending limit of $10 max per cell. My feeling was that anything above that was really unlikely to be worth the money.

Berky99:

You're right that it's just probably not worth reviewing something as pricey as the Mugen. As a more general comment, people need to recognize that there is typically a well researched maximum energy density for various battery technologies. In other words, "spending a bit more" might get you an 1800mAh cell instead of a 1000mAh cell, but that doesn't mean that "spending a bit more" again could give you another boost from 1800mAh up to 2600mAh. At some point, there's a ceiling, and it doesn't make sense to pay more money hoping for higher capacity cells. Arguably you might improve other aspects of the cell, like the quality of the protection circuit, perhaps the durability of the casing, etc, but you won't continue to see returns beyond the energy density limitations of your battery technology.

ziddey:

Actually, there are a couple problems with that approach. For one, as you've mentioned, voltage does not scale linearly with remaining capacity. In fact, that's why electronics have so much trouble accurately assessing a cell's remaining capacity. It's not just non-linear, it's also a bit different from cell to cell. The other challenge, is that as voltage drops, so will your current (EDIT: assuming you're just discharging into a resistor), meaning that it's not a constant current rate of discharge.

If you DO undertake a test, you don't need to artificially stop it at 3.2V. People may not realize this, but the protection circuitry is not in the phone, it's in the battery pack itself. If you pull apart a cell, you'll find it there. It shuts off the discharge at 2.5V.
[HTC Sensation] mangio85:
wonderful!!
[HTC Sensation] Berky99:
rhd-android, you are the dude.

If anyone finds any means of keeping this batteries safe on the go please let us know.

I've ordered two more batteries (for keeping my GPS app and music going during a long bike ride) and really want to keep the cells secure!
[HTC Sensation] rhd-android:
A few people have asked for the URL to the generic cells that hit 1710 with a rating of 1520. What I've done, is I've ordered 3 more of those cells myself (they were only $3.50 after all!). I'll test all three. Assuming the results are consistent with the first test, I'll post the URL.

It's important to be cautious though. Chinese eBay sellers often cycle through batches and manufacturers quickly, and seem to have no objection to substituting one "similar" item for another. So even if my next three pan out, it would be worth employing some caution if you choose to buy a few cells yourself. Perhaps grab 1 at a time - they're shipped free, so there's no price benefit to getting a bunch upfront.
[HTC Sensation] Miha2e:
How about "Mugen Power 1950mAh Extended Battery for Sprint HTC EVO 3D / HTC EVO 3D X515M/ HTC Sensation/ HTC Sensation XE / T-Mobile HTC Amaze 4G" ($42) and "Mugen Power 3600mAh Extended Battery for HTC Sensation / T-mobile Sensation / HTC Sensation XE with Battery Door" ($ 96)? What are their real capacity? :confused:
[HTC Sensation] aznprodgy:
unless youd like to donate to the OP, I dont think he will be testing out those batteries lol. I think he said his spending limit was around $10 a battery
[HTC Sensation] Miha2e:
Clearly, I thought they were all tested. I'm curious cause I have Mugen Power 3600 mAh with Battery Door and I think it should work longer than 3 days
[HTC Sensation] Rusty!:
If you spend 96 on a battery, you need your head seeing to!
[HTC Sensation] Miha2e:
I did not spend $ 96, I was given :fingers-crossed:
[HTC Sensation] LPChris47:
The HTC Sensation Chichitech battery is another popular cell on these forums. Anker and Chichitec have had some epic battles in the past lol.

http://www.amazon.com/CHICHITEC-T-m...3417291&sr=8-8&keywords=HTC+Sensation+battery

Any chance we could get a test on that? I'm more than willing to donate $$$ for the cause if other XDA members pitch in :)

Great work in the OP!
[HTC Sensation] rhd-android:
Sure, I'd be happy to test it, but I think I would be tapped out in terms of the cost on that one. It's more than I wanted to even spend originally, but certainly now with $70 or $80 invested in these batteries so far, I'm not sure that I would want to spend $25 on just one single additional cell. But if anyone is willing to order me one, I'll put her on the testing rig and report the data.

I've got a lot more cells now than I need, so I could even pass along one of the cells that I've already tested, to anyone that wants to arrange for a new cell to reach me for testing. I'm not sure that I would have anything as valuable as the Chichitech to offer in return, but I could certainly send someone an Anker as compensation.

545148AR is the 1700mah

sounds like a good idea weighing the batteries. rhd-android, would you happen to have a scale to weigh the batteries you have? might be interesting
[HTC Sensation] fahad.mq:
rhd-android, thank you so much for posting your comprehensive Sensation battery comparison. It must have took hours upon hours testing all of those batteries and crunching the stats comparison (not to mention buying all the batteries too)! Outstanding post, you're the latest example of why I continue to enjoy the Sensation and the XDA community around it. Keep up the great work!
[HTC Sensation] rhd-android:
Just added the "Max Power" from DealExtreme. At 1320 real capacity, it's not the worst cell I've tested. But it's nowhere near the claimed 2100, and at $5.80 it's certainly not the cheapest cell tested. I've added it to the OP and also reorganized the capacity charts to make it easier to draw conclusions from them.

Inevitably it will be a balancing act for each user. Do you care more about capacity per dollar, or more about absolute highest mAh?

If

highest mAh

is your only objective, then choosing a cell is probably going to take you to the Ankar (1750mAh actual) Of course, the downside is that Ankars vary in price depending on when and where you find them, and they may not be the best value out there.

If

best capacity per dollar

is your only objective, then the two unbranded generic clones (#1 and #2) are the clear winners. The challenge here however, is in being able to relocate the exact generic cells I tested. Absent branding, and given the frequently "swapping" of one generic item for another by Chinese gadget sellers, it may be somewhat difficult to source these exact cells reliably.

If a

balance of the two metrics

is what you're shooting for, then the Aoonen or the Business Gold might be decent shots. They both get you in with a decent capacity (1610 and 1420 mAh respectively), and score above average (though not the highest) on the capacity per dollar scale. I would encourage a bit of caution with respect to the Business Gold battery, as there have been a few variants that I've observed online.

My conclusion? I started this project largely to help choose a cell to buy ten of for an upcoming stretch of travel. It's ironic that thanks to all these batteries I've collected for testing, I no longer need to buy any more! But, if I still needed to make that decision and jump in with a cell choice, this would probably be my approach:

I'd look for a great deal on the Ankar first. If you can find one for less than or equal to the $9 I paid for mine, then you're getting the highest tested capacity at a value per dollar figure that is still pretty good (and gets better the lower you get below $9).

Failing that, I'd grab the Aoonen. It's going to get you 92% of the way to the Ankar's capacity, at a lower price of around $7.

Failing that, I'd grab a Business Gold, while being careful to order one that matched the label in my photo.

* At the same time as doing the above, I'd probably consider tossing $3.50 at the "crap shoot" that is the "Generic Clone #2". When it arrives, test it with a software battery testing app. It won't give you as accurate a picture as my testing did, but it should certainly be okay for relative comparisons, which will give you a sense of whether it's the same miraculous cell that I lucked out on.
[HTC Sensation] rhd-android:
Hey all,

I wanted to make one final comment in this thread. Sadly, I've moved on from the Sensation, and have jumped ship to a Samsung phone.

It kills me, because I love HTC phones, and I think they produce the highest build quality Androids on the market. But (unsurprisingly based on this thread), removable batteries really matter to me. HTC's trend towards non-removable batteries in their flagship phones has destroyed them as an option for me personally.

But, one final battery to toss in here. I'm not going to photograph it, nor add it to the graph, but it's a neat one to mention. This guy:

http://www.ebay.com/itm/261047964534?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

I was done ordering cells until this one caught my eye. 90% of my motivation to order it came from curiosity as to whether it would actually arrive looking as dull and boring as it's photo. It did. But for $4.75 shipped (when I ordered it), and a real capacity of 1420 mAh, it ended up being a moderately decent value. As always, if you choose to order one, please do so cautiously. It has been a month since I ordered my cell, and stuff changes all the time with eBay sellers from China.
[HTC Sensation] Arodg25:
wow just proves to me again that if you want to know something, in my case which battery to buy. Just do a quick search and out of the 7 billion people on this planet someone has tested the hell out of it to give me an answer. Thanks so much you saved me and incredible amount of time.
[HTC Sensation] qpqpqp:
Thank you for the useful and informative research. Do you happens to have the name of the seller who sold you the generic number 2 battery? I also noticed that most of the battery prices listed here have gone up drastically.
[HTC Sensation] rhd-android:
Unfortunately I don't. The problem, is that I wasn't able to match it to the item ordered on eBay. Annoyingly, they often don't indicate their ebay username or item number inside or on the actual package. If the item doesn't match the photo precisely, it becomes near impossible to identify the source of really similar looking cells.
[HTC Sensation] Laurens87:
Thanks for this thread rhd-android,

Need a good battery for my sensation, will buy the Anker.

I also want to mention: be careful with buying the gold battery. I owned one for my Wildfire (buzz), had same capacity as stock for a week, rapidly decreased afterwards. Perhaps battery is build different since this one is for a sensation but looks awfully the same.
[HTC Sensation] rhd-android:
Frankly, I think the issue is that the "gold battery" isn't a brand, model, or consistent singular product. Someone likely released "a" gold battery, that got favorable coverage somewhere, and then the competing battery manufacturers/distributors changed their stickers to look similar. This is a common issue, and it's one that can be difficult to overcome in a shootout like this.

If I was doing this all over again (and I may for my new phone), I would do it a bit differently. I would post links to the actual cell purchased. But I would also make a point of coming back a month or so after the review to remove the links. Premise being that there is value to readers knowing exactly which cells I ordered, but that this data becomes less likely to be accurate as time goes by, and sellers change stock.

I was pretty hesitant to post links when I started this thread. I think I only had 3 or 4 posts to my name on XDA, and was concerned with the optics of this testing looking like I was actively promoting a particular seller or cell (ie, looking like spam). At the same time, that probably made some of the results more difficult for people to actually utilize. So next time, I'll link people up, with lots of warnings about only cautiously ordering one cell at a time, testing them for themselves before ordering more, etc.
[HTC Sensation] Laurens87:
Again, thanks for all your testing. Even without the links you provided lots of useful information.

I mentioned my experiences with the gold battery to provide that little extra information. You could be right about the copying activities of the battery firms. However, there is a bigger risk when buying the high capacity gold battery. So I think its highly recommended to pick your #1, the Anker (I will buy it), or #2, even when you need to spend a few dollars/pounds/euro's more. :good:

I wish you happy battery testing with your Samsung!
[HTC Sensation] rhd-android:
I agree with you, and I will say this:

- I needed 10 or 15 batteries for travel, but now that real life has returned, it is the Ankers that get used almost exclusively. So for normal circumstances, I think a regular person would do well to keep their stock battery, add one or two Ankers to their collection, and be done with it.

Thanks for the happy testing wishes with my Samsung. Unfortunately, it seems that I've actually managed to buy a Samsung (the GS2 HD LTE) that nobody else on this freakin planet owns :(

RANT: God damn it why doesn't HTC quit with this non-removable battery BS? I'm simultaneously sad that they're failing as a company, but angry at them for doing things that make it impossible for me to buy their phones in support. HTC makes the best hardware, period, and I'd stick with their phones for life. But if I can't swap a battery, it's a non-starter. My phone is in my pocket every waking hour of the day, even when I'm wearing pajamas. Plugging a phone in during the day is not an option, and I use my phone far too much for any device (no matter how large a cell it uses or how energy efficient its software) to last through a full waking day.

Even if removable batteries didn't matter to 80% of your market, why would you alienate the other 20% that it matters to, for no apparent gain other than having a uni-body design? Doesn't make sense. That's an Apple-like aesthetics decision that betrays functionality, and nobody but Apple can get away with that. RANT over.

[HTC Sensation] bsoplinger:
For high capacity over sized the Seidio can't be beat, especially the CowBoom offer or failing that eBay. Search for Platinum extended which is the name of the specially packaged for BestBuy versions which are going rather cheap right now.

For standard sized you can't go wrong with the Anker (special?) mentioned in the OP.

Cell Capacity measurement

Hi rhd-android,

i've read your post about your measurements of HTC Sensation batterys.

Because i'm very intrerested in batterys and their capacity, i've done some measurements, too.

Coincidentally i used the same setup like you. I recorded the V and A values while discharging the battery by using a 10 Ohm resistor as consumer load.

I only own a used original HTC Cell and a Cell from Anker. I got a value of 1644mAh for my used Anker battery. Should be a correct value while you got about 1750mAh for the new cell.

How do you record the values?

I developed a arduino based analyzer for batterys from 1-20V of any capacity. Still i'm not sure about the precision of my device. Do you use a professional device? Propably we could compare some values. Soon i'll buy a new Anker cell. I'll do the same procedure than you. Charge, discharge, charge, measurement. I'm excited to see the results.

Did you analyze other batterys, too?

Regards,

Chris

pls pn!

I don't know about the stock one, cause I bought an used Sensation with the battery that couldn't even charge to 100%.
[HTC Sensation] maciclazar:
I bought MS mobile 1200 mAh and it last much longer then original sensation's battery. I ve downloaded battery monitor app and it shows that this battery has a 1750 mAh and original one 1530 mAh. I don't know if this is true but my battery life increased :good:

I have Mugen Power batteries for 1950 and 3600 mAh. Just after purchase and 5 recharging there was about 2000 mAh for 1950 battery and 3500 mA for 3600 (calculated with Battery monitor widget app). Real use appoves this values.
[HTC Sensation] CulCharge:
Yeah, mugen are expensive, but they always manage to pack little more power into the battery. Sometimes this causes the battery to be little bigger than original, so it's a bit harder to put it in, but the power given is great.
