Good thinking. You're results are going to be very helpful, we all appreciate you doing this for us so we get the bottom-line on these eBay batteries.

I have one from the seller in CA @ 1600mah, one from the seller in NY at 1600mah. Which is the one you're doing testing on? I notice the one I got from the seller in CA (Diamond Bar, CA) slides into the phone just like it was meant to be. The one from NY needs a little push to get it in, and it's a VERY snug fit... hard to get it out. Bit concerning as the nature of batteries is they expand\shrink slightly.
[HTC Inspire 4G] bgweed:
No big deal - gives me something to do during downtime at work. I know there are lots of people who dont put faith in the "i think it lasted longer!" reviews, so more than worth the 1/2 day it took to drain the battery and the 10 min it takes to plot it out.

Good info on the battery options. californiarailroader is doing the log on the ebay battery for me. Here's his post about the source:
[HTC Inspire 4G] bella92108:
That's the same as the second battery I have. It's the one that's a REALLY snug fit inside the phone :=)
[HTC Inspire 4G] cushcalc:
Removing battery is very difficult, after removing cover.

I've got removing the battery door down. It gets a little easier each time I try. But the battery itself is in SO tight that it definitely does not slide out from gravity or shaking - I have to carefully pry it a little from each side with a jeweler's screwdriver until I can work it out far enough to get a grip on it. Has anyone else had this issue?
[HTC Inspire 4G] bella92108:
Make a tiny pull tab using a piece of scotch tape, so you can just pull the tab and the battery will come out... solves the issue :-)

[HTC Inspire 4G] bgweed:
Maybe you could make a log with your other ebay battery for comparison? :)
[HTC Inspire 4G] DeathmonkeyGTX:
I'm sorry, but I'm seeing a sh*tstorm of inaccuracies in this thread. HTC made one official extended battery that I'm aware of; it's sitting in my Rhodium right now. It's a 2150 mAH as opposed to 1500, and it is physically larger. Seidio lies about their other batteries that are the same size as stock HTC batteries but somehow have a marginally higher capacity. They say they're bigger, but if you test it with proper equipment you'll see how full of sh*t they are. They're not as bad as the cheap eBay batteries or Mugen, but they do lie to you.

I think it will be impossible to put a bigger battery in the Desire HD because the battery cover is way different than any other HTC device I've had. The whole back of the Rhodium and everything before it came off completely, thus allowing for a larger battery and a different back cover to be installed. That is impossible with the Desire HD. The only thing you'd be able to rig up is a case with some Li-Po cells in it that plugs into microUSB kinda like how iPhone 'tards extend the lives of their iDevices without taking them apart to replace the battery...

If you don't believe me about the battery merchants who claim a higher capacity in the same form factor as an official HTC battery is a liar, look up "Dougie" on this forum. He had a fantastic thread in the Rhodium section last year and did extensive testing. I even sent my 2150 HTC battery to him for testing, and it was the only battery to have exactly the rated capacity. The other HTC batteries have ~93% of rated capacity. Cheapo Chinese batteries have 40-80% and Mugen's 3600 mAH monster only had 66% of it's rated capacity:eek:

I'm frequently away from any variety of charging so I'm a freak about battery life. I don't know how much research I've poured into these bastards but it's definitely a lot.
[HTC Inspire 4G] jamespaulritter:

[HTC Inspire 4G] lrs421:
I thought I'd share my experience. I too purchased the Seido and it appears to offer the same battery life "maybe" slightly better than the oem. I use my phone a lot and get through a day just fine, but I could do the same with the oem battery.

It was $40 so I'm going to use it everyday BUT if I could to it over again I would just live with the stock battery. Love my Seido case and holster though ;)

After getting burned with Ebay BlackBerry batteries I would not go that route again.
[HTC Inspire 4G] californiarailroader:
I still can't understand how they can charge so much for these batteries, the markup on these things must be HUGE!
[HTC Inspire 4G] bella92108:
When I was in high school I worked for RadioShack and we would sell a 24 pack of AA batteries for $14.99 and our cost was $0.63 ....

We had replacement startac batteries that were $129 and our cost was $17 .... and you bet the manufacturer and distributor still had to make their cut before it got to RSH.

Crazy huh....

For those folks with these 1600 mAh miracle Chinese or NY batteries, from a terminal emulator app or ADB shell (root is not required), enter the command:

[SIZE=3]cat /sys/class/power_supply/battery/batt_attr_text[/SIZE]

The number you see listed as "FULL(mAh):" is the real capacity that the battery is reporting to the OS. I'm guessing that no one will see a number much greater than 1230, which is what the stock HTC battery reads.

Just to give you an idea .. I had seen in other forums/threads that these Chinese/NY 1600 mAh batteries are only reporting back @ 956 !!!!!

Now you'll see from the images below .. the first being HTC's original battery showing 1230 (as it should) .. I purchased the 1600 mAh from Brooklyn NY (pic'd) and see .. the Chinese battery reported back the same mAh as my original !!!

So these are NOT 1600mAh as advertised.
[HTC Inspire 4G] bella92108:
I don't think this is an accurate test. I have 4 batteries: 1 original HTC 1230mah, 1 aftermarket 1500mah, 1 aftermarket 1600mah, and 1 Seideo 1300mah.

I did all 4 non HTC and all 4 show 1230 mah so clearly it's not just coincidence, there's obviously something wrong with this test. It's likely just programmed with the factory battery spec to output that result.

If I'd gotten 800, 1230, 1240, 1250 I'd lend some credibility to the test, because then 4 batteries from 4 sources would be proven less than advertised, but when four batteries test the exact same, I pause in skepticism.

Holy crap some people in this thread are dense... If you actually want to objectively test the capacity of a battery then message Dougie. He already spent ~$300 on equipment to do so and if you're nice you can probably send him some batteries to test. The crappy IC in the battery and the power management in the actual phone aren't very accurate.
[HTC Inspire 4G] bella92108:
Seriously, drop your "tude" ... you clearly don't understand battery technology. Contrary to all the marketing hype, there's not a lot to a battery, and at the end of the day the end game is all about the mAh the battery puts out... and if the batteries aren't putting out, it's likely because it's trying to fit 10 gallons of gas in a 7 gallon tank.

Seriously? You're one of those, ehh? How about YOU get YOUR Masters Degree in EE, then you'll know... wait... just take an electronics 101 class at your local community college.... wait... just GOOGLE batteries and learn how the technology works, and you'll soon see how the physical and chemical configuration works, and understand that it's all about size and power consumption, and you can re-arrange the cells within a battery casing, but there is NO way of reconfiguring a battery the size of a HTC Inspire's battery to get a 40% increase in mAh... period.

Why do you think every credible add-on battery for cell phones have been "chub" batteries that clip on or extend out from the phone in some way? It's NOT rocket science, it's quite simple... and battery technology really hasn't changed much. You want bigger life? You need to have bigger physical size.

If you need a $300 test to comprehend, go for it, but you'll still look like a sheep following 1000 others rather than thinking for yourself. But hey, that's the American way!

[HTC Inspire 4G] scottypimpin636:
+1, i've done a ton of research on batteries when I played airsoft and I used to be pretty big in RC cars as well.

There are higher quality batteries which are important for motors in RC cars but as far as a cell phone goes you just need juice to last. The higher quality cells will hold a stronger charge so if you buy a $5 battery it may not hold as much as a $20 per say. The higher the Mah, the more juice the battery holds and the longer it's going to last... period!

You can't fit 2 gallons of water in a 1 gallon container either.. You wan't bigger you have to go bigger.
[HTC Inspire 4G] maevro:
I am more than happy with Seidios 1300mAh OEM battery. People think 50mAh doesnt make a large difference but it does, especially with HTCs battery conservation software.

I was a rep for HTC, Nokia, I-Mate, Etc and obviously there are different factors in battery drain. I personally would rather have a quality battery then some cheap generic.

I let it cycle a few times and I get great battery life. I use a lot of data including TV, SMS, MMS, Email and internet.
[HTC Inspire 4G] buddy17:
But, what people don't realize, is that just because a battery says 1600 mAh (not Mah, by the way) does not mean it really is a 1600 mAh battery, as proven in the many battery tests on them.

[HTC Inspire 4G] DeathmonkeyGTX:
Holy crap, Batman; this thread hasn't died yet? Pick up your phone and remove the battery cover. Do you notice that it is METAL and the entire back of the phone doesn't come off like it did with every HTC device that has supported official and third party giant batteries? It will not fit and unless you potentially destoryed the phone with a dremel and extensive fabrication to fit a larger battery it's not going to fit.

I thought I'd return this thing becuse of that, but then I got the battery conditioned and I get at least a day out of it. If I'm going to use GPS with maximum screen brightness and streaming flacs from my house with AudioGalaxy I plug it into the 5V/1A car charger. If I leave it on EDGE and don't use it for much I can get 3 days between charges. I'll probably wrangle a week out of it next time I go on vacation.

Honestly, I would expect HTC to release some type of higher capacity battery in this form factor in the future, but I highly doubt I'd pay all that money for another few hours of idle phone time.

If you are willing to go through all this trouble for an extended battery, then why not just get a small portable battery pack for < $25 ? Run until you are low, plug it in for a recharge, and you're good to go. Have one in your other pocket, at work, in a laptop bag, or anywhere else?

The reviews given in it are pretty good?? what do you think??
[HTC Inspire 4G] bella92108:
HEHE, did you even read the reviews, or just stare blankly at the stars:

Review 1 - "It lasts at least 75% longer than the stock 1200mAh that came with the phone." ... well even if it was technically possible to put in 1600 mAh, it would never last 75% longer. It's someone convincing themselves that they see jesus in their breakfast toast. It's amazing what you'll believe if you try to convince yourself of something.

Review 2 - "After the third charge cycle, this battery worked just as well as the original battery that came with the phone." ... just like the dozens of other reviews from batteries costing 1/10th of the price, they all "work" but just like or slightly less than the OEM battery, making it a replacement, which if you want a replacement battery they can be had for far cheaper.

Also, notice the names.... Russ, Cherry, Quill, Harold... comon. These are names that I'd bet money were thought up by this Amazon seller. Just think, if you're an Amazon seller, what's the best way to raise your price and get more people to buy? Create reviews that praise it, then spread the word.

I personally have ordered (and returned) THIS battery, and can say it's a good replacement, does exactly what any $5 battery from eBay does (which is why I returned it)... starting to think until HTC redesigned the handset there's not going to be an internal power method to get any more life out of it.

But hey, that's my two cents...

Hey bella, thank you for toning your posts down a bit. I just read several of them without finding one inflammatory post. The thing about dual-core battery draw was close, but mainly due to the fact that the dude you bashed is correct. I don't remember why because it's the weekend and as such I'm pretty ****ed up, but two cores running at 500 MHz use less power than one core running @ 1 GHz. Also, the ARM design in our phones is Cortex A8 whereas all the new dual-cores except for the one in the Sensation/EVO 3D are Cortex A9 so it's more efficient clock-for-clock on top of the inherent energy savings of a multi-core CPU. I could explain it better while sober, but it is truth. I'm pretty handy with electrical engineering and my brother is a particle physicist and we're both electronics nerds so we tend to figure out everything there is to figure out in all of our toys that cost a good chunk of change.

I'm waiting to see if they (being name-brand companies) figure out that all they have to do is get a small adaptor for the normal battery spot, run a wire to a bigger battery that is in a case that fits around the phone. Ta-da, extended battery and a case all in one.
