Ok, my battery is weird it doesnt last long. it dropped from abut 95% to 70% over night, with checking email every 30 minutes with k9 and the mail app every 4 hours. My phone doesn't last very long either, I haven't tested it fully. I always keep charging it, when im in the house.
I bought it from T-Mobile and i could swap it. Should I?

Might be worth it, I have Friendstream updating default setting, Googlemail (although it's push) on at all times, browsing a fair bit (on mobile net and WiFi) and a few calls and it last 2 days-ish...I'm using a generic Desire on latest FW
Mine's the same. I didn't think it would be worse than my old BB Bold for battery life, but it really is very poor. I don't think you have a fault, it's just the way it is.
I wondered about closing background apps but I've read that having them open doesn't impact battery life. I do have a few background things going on though that will affect it, so maybe I need to consider if I really need them or not (frequent email syncing, contacts/calendar syncs, etc.).

Have you put the phone down for long periods in-between uses, or have you spent a fair time writing emails or just playing with it? I've spent a fair time on mine but not constantly, and no more than I used to with my BB Bold. I used to writing emails constantly on my Bold and the battery would last a good day, but until I'm used to this keyboard I won't be doing that on my Desire.
So It won't make a difference if i swap it? I also didn't do the standard charge at the start. Couldn't resist playing with it. So It was on charge while playing with it. Could that make a difference?
I'm in work a lot and I'm not constantly on it - just check for emails/SMSs every hour or so so prob spends a lot of the time in standby. I'm on it more on the weekends but it still lasts well into day 2

If it works otherwise then I doubt there is a fault that would cause the battery to run down but nothing else not to work.
Not charging the battery at the start is one of those things that some say makes a difference, other say it doesn't. With Lithium-Ion batteries I always thought they didn't need that initial charge, but I can't say for sure. Anyway, what might help is if you did a full charge then a complete discharge (use it until the phone turns off) then a full charge again. With older batteries at least, that tended to help them last longer.
There a a few threads on this alread here and on the Android Forums.
There is a problem where the phone when charged left on, only goes upto 98%. However the phone will soon drop to 90% and lower quickly, indicating the phone has not charged properly.
If you unplug and reconnect, it will go back to 100% but almost as quick as tying your laces, it will go from 100 to 98% and continue to drop.
It could be faulty batteries.
I was hoping the FW update would fix but it hasn't as I found out last nite.
Or should I just buy another battery?
I've been having similar issues,
I get much much better battery life without mobile networks on, and alot of application crashes/phone reboots to get it work like I expected.
Took some data:
1hr of phone in sleep mode w/ mobile internet on = 4% battery
1hr of phone in sleep mode w/out mob internet on = >1% battery
So I can get a good two days if I don't have any internet with moderate use, but about 16 hours with internet always on and moderate usage. If I really 'rag' it and use alot, I can get about 50% done in a few hours (not constant use either, just alot of google goggles mainly!)
This coupled with the crashes and reboot made me get an exchange, I'm just hoping it's better, and really hoping its not worse..
Wish me luck, I wish you all the same.
After couple weeks my original battery seems to last longer - I do with 1,5 days now (with some browsing, 3G, occasional GPS and bluetooth, weather & gmail sync, dl apps from market etc). So it might be true that after the initial couple weeks of usage and charging the battery performs much better.
Intrestingly T-Mobile promised to send me a new battery over a week ago. As it never arrived I called them and was told they dont have any... but they would credit my account with £20 to buy one. Today... I received an extra battery from T-Mobile!!! No idea what is going on - and if I still have that £20 credit in my account
I will give that new battery a loooong first charge, see if it helps.
what about the 3000 mAH batteries?
Are they any good and would it work for the Desire?

Won't help, once it's at 100% the charging will stop. There is no such thing as 'long charging' li-ion batteries or 'trickle charge' a li-ion battery.
You can try to do a full first charge (until the green light burns) and then fully discharge (until the phone goes off). Then fully charge again. This will calibrate the battery chip and make sure you see the correct percentage.
If battery life is still no good then it's because you use the phone too much. Read: constant weather updates, friendstream updates, push mail and other stuff that constantly use the mobile connection. Also turn off gps unless you need it.
Turning off those services and turning off the 'always on mobile connection' can double your battery life (read: standby time).
It's not something magical, it's completely normal. If you want the phone to do a lot, it will obviously use a lot of battery.
Just for the sake of it, put the phone in airplane mode. You will be amazed how long it will last.
It's the main problem with modern mobile devices. Battery usage and capacity are no longer in good balance. What we need is more compact batteries that have more capacity.
At the moment it's clearly a comprimise between battery size (thus capacity) and battery usage. It's up to you to see how much you want to comprimise.
And so far, with every HTC phone, after a few (radio rom) updates battery life increased.
And... what everyone seems to forget, when you first get your phone you will fiddle with it.. a lot.. And once you have it for like a week or two, you start using it differently. Usually ending up with better battery life!
Try to run it down to around 5-10% after each full charge, but don't let it go completely dead if you can avoid it. Do this a few times and you will notice an improvement. Plus of course, when the novelty wears off and you use it less the same will happen.
Back when I got my Touch HD it would only just last a day, but by the time I was on the upgrade path I could get 3 or 4 days out of it!
Just to confirm, I was a bit worried at first about the battery life of the Desire. The first 2 days I could only manage to get 7 / 8 hours out of it. When I turned data sync off at night, it still lost 40% of the battery .. doing absolutely nothing.
However as mentioned before, I'm now on day 6 and now I can easily get 36 hours of browsing / texting / calling 2 hours + / even playing occasionally games. At night, without data sync, it drops just 4%.
So if you're worried about your newly acquired Desire's battery sucks, It really needs some calibration. After a few days it'll work as you wish.
T-mob battery
Hmmm.. Not sure what T-mob is up to. They promised me a £20 credit to by a battery (they didnt have any in stock) then I received the battery in post. I called 150 and they confirmed the £20 credit is still there for the next bill...
I couldnt be happier with T-Mob! Besides this I got 100txt/100min, plus 60 min included to Eurasia, Internet and 40 free txt to Europe = all for £10 a month!
Now I just need a case for it... waiting for the PdAir one to come, had one for my Compact IV and loved it. Its the flip one that opens upwards not down, so wont mess with the hardware buttons.

I really hope that's the case...
I got my Desire on Tuesday, first use was on Wednesday.
Yesterday (Friday) I put the Desire into Airplane Mode - I deactived everything. Turned off WLAN, mobile Internet, Syncing off manually before I went into that mode, just to be sure. When I went to bed, I had 72% battery left. When I woke up...50%...seriously, what the f...?!?!
8 hours of doing absolutely nothing uses 22% battery?! It's really annoying at the moment, absoluetly unusuable unless I'm home and know I can plug it in any second. When I'm out, I don't even dare to use mobile Internet, because even without it it only lasts till I get home (no WLAN, no mobile internet, just using it as a "telephone"...).

You expect the phone to stay turned on without using any power? This isn't a dumb phone, it is running powerful components and 8 hours doing "nothing" is relatively long time and the power usage of keeping those components powered at idle levels is going to add up no matter what. If you can't bear to turn the phone off if you can't control your usage, carry a charger or battery you should have got a dumb phone.
Bear in mind that the full capacity of the battery won't be reached until several charge/discharge cycles have been done, especially when you are using the battery for the first time on a new phone or on a phone with updated firmware. I noticed this while flashing custom ROMs on a previous handset. I'm sure we will also notice improved battery performance when firmware updates become available.

So you wanna tell me 20% battery loss in 8hrs airplane mode is normal? I hope not.

Hey all,
I am a new owner of a HTC Desire, have used this amazing device for about 2 weeks now. All is well, except for.... the battery life.
Here is my scenario, tell me if this is the "norm":
Unplugged from wall charger at 8:30am, by 9:16am (total unplugged time of 46mins), I had used 18% of the battery.
I had a 7min voice call, afterward a 2min video recording. While on the voice call, I had it paired to my bluetooth headset (Plantronics).
Power left in the battery: 82% (4021mV, 30.0 degrees celcius)
All the standard items loaded as part of the Android OS. I have no data plan yet, so 3G was off, WIFI was off, GPS was off as well. Lastly, brightness was set at 40%.
Is this normal? to loose 18% of my battery within that timeframe and also with the type of usage I went through?
Thanks or any response..!
It could be because your screen was on? If your battery is still bad after 2 weeks try to get a replacement.
I have learned to just accept losing 1% in 1min under heavy use.
I reckon I could empty the battery in an hour and a half with the right conditions. It just sucks, start carrying your usb cable round with you and keep an eye out for USB ports you can nick some juice from. If your lucky you'll get through the day with charge left and not lose your data cable (I'm on my fourth).
Some people claim to get several days use out of their desire. They must have a pact with the devil or something because the best I have ever seen is a day and a half.
This is the common issue for new Desire users, so don't worry its normal what you are facing..!!
-Trust me when i bought my desire i freaked out after heavy use the battery wouldn't even lost for 6-7 hrs..!!
-I had never got one full day out of my desire..!!
-So i did some serious research on this issue and came out with some Awesome solution..!!
-i have written the solution in my blog here:
http://harishanswers.blogspot.com/2010/09/disappointed-about-battery-life-of-your.html
-After reading that post ,follow the instruction that i have given at the last.
i hope you got the solution for your problem

- SetCPU: (Max 1036800, Min: 245000) Interactive scaling.
Not using the phone, while in standby it lasts basically forever. The longest I've gone without recharging is two days, light/none use.
When I finally recharged it the phone claimed to have about 60-70 % of juice left. Making a phone call would probably leave the battery with 40 %, LOL
Normal use gets me through the day with about 30 % battery at the end of the day. Ca 12-16 normal use.
Hard usage, my phone holds up about 6-7 hours time. When I say hard use, it's constant use.
Thanks for the replies everyone.
My situation hasn't really improved, even with a "app Killer" added to the equation.
like mercianary mentioned, I have been carrying my adaptor and USB cable where ever I go! Not the best method.
I am thinking of buying one of these to carry around..

Try using JuiceDefender. Should boost your battery.
Those tasks are close to the heaviest usage possible so nothing unexpected for a completely stock device. Battery drain is always subject to usage.
Albeit 18% sounds a tad high to me.
Did you verify you were starting at 100% and it didn't drop to 90% within seconds even with no such use (like experienced by many)?
-----------------------------------
- HTC Desire via XDA App -
I've always been impressed by the battery life on Defy ever since I owned it. I haven't owned other smartphones before to be able to make a true comparison but using electronic devices for a long time I can tell the battery usage on Defy can be impressive. However, there were times I noticed the battery was drained so quickly.
In my latest watchful examination of battery usage I have achived to use only 30% of the battery for more than two days. Here is a summary of my usage in the past two days;
4 Hours Music Playback (PowerAmp)
30 Mins wireless
About 16 hours airplane mode
No phone calls on my mobile but I did dial a number several times
I have fully charged the mobile on Friday morning and on Sunday morning the battery has 70% charge.
Hint:
As it was stated in user manual it is recommended to charge the phone from mains socket whenever is possible. I can confirm that I've seen battery improvement after recharging the battery by mains socket after several times.
Since I don't have a use for MMS I have renamed the APN server. The same trick can be used to disable data and that saves battery life too if you don't use your phone to push/pull data.
In the past 2 days my network type has been set to 2G only. The automatic setting certainly have dramatic affects on battery.
Before going to bed I put the phone to airplane mode since the reception in my bedroom is very weak and this increases the battery usage.
With simple measures the battery life can be extended (noticeable) more than what you'd expect.
I'm very pleased with the battery usage so far. Nonetheless, I will buy a spare battery as soon as it is available in the UK.
Happy New Year XDA
Yours are the most impressive stats for the battery use. I've set my Defy into saver mode, and the network data to 2G as well (I only use it to sync up with Gmail (plus Calendar and Tasks) and my employer's Exchange email) and get down to 50% after two days of moderate use, which is enough for me not to worry about running out of juice if I'm away from home for a few days. Yes, the Defy can be pretty frugal with battery use.
I ended up having my original Defy swapped because of concerns that the battery wasn't up to scratch and the new one's been brilliant.
I'm in 3G all the time, never put it in airplane mode, and after 62 hours I still have 20% left - that's with me having used it for some calls, texts, web browsing, facebook and a good couple of hours of Angry Birds as well.
Definitely the best smartphone around for battery life IMO.

What does mains socket mean? The wall outlet (I am in the US).
If so, how else would you charge? Computer USB?
If its the bit in the wall that the electricity comes from then its the same thing :L and yeah you can charge it from a computer USB but it takes a little bit longer

If Motorola Defy's screen size was 4" and it had Froyo ROM already I would have bought two of them just out of excitement.

Yeah, seriously.
I'm not talking about hours of calls, more like 15 minutes or so. Maybe an hour or two total web browsing and facebook and perhaps an hour on Angry Birds.
Part of the reason it lasted so long was that I just didn't touch the phone on Christmas day at all, so that was 24 hours with basically zero use, which is unusual.
The next charge last more like 2 days, which I think is closer to how I'll be using it normally.
if you put it in air plane mode, and a couple hours later u turn air plane mode off. will u get all of your notifications? like calls,texts and stuff that people sent to u while the phone was in airplane mode
There is true gem on the Market named JuiceDeffender Beta - I used it since my Milestone and it really does what it says it does. All the hints you mentioned already included in the program and are being controlled by it. For example, as soon as you display turns off your network automatically switches to 2G. In paid version you can even adjust processor's speed when needed (underlocking of course, in terms of battery saving) However i am currently on free version and it's enough to make the battery last almost twice as longer.
I had some problems installing it on Defy, but they were all gone as soon as I rooted the phone.

How did you get the 3G -> 2G to work? I can not enable that feature, as I am not using a CyanogenMod rom and I can not download/install AOSP helper as it suggests. I am using the beta and UltimateJuice, which I purchased after seeing what features it provided. I'm using the CPU features to do what SetCPU did for me - no need to have two packages with overlapping features installed.
*update*
From the author of JuiceDefender:
In practice the only ROMs known to work are CyanogenMod (any version) and the Nexus One stock ROM..

I've had my new desire z about 2 weeks now, and am utterly dissapointed by a frankly dreadful battery life.
It's my second DZ, given the original was nicked, but (kicks self) wasn't insured, so was purchased from a supplier that shipped my phone from Hong Kong (I live in UK, and the new phone is an identical model, except for a slight difference in key layout - A2727 I think is model number)
The original phone would give me over two days life with very low use, which i considered to be fair for a decent smart phone.
The new phone barely gives me 10 hours with no use. I've done a couple of tests - unplugged it at 2am, but 8am it's at 30% or lower. This was done with all data connections turned off.
If i leave the new phone to go dead then that's it - it won't charge. The only way i've found to get juice back into the battery is to hold it in my old touch-pro 2 until it's charged enough to charge from the desire.
Last night was the clincher. I've gone out with some friends to the pub. I had a conversation over it, and checked my battery life - 42%. As a last dith effort i factory reset the phone at that point to rule out a mischevious app, and checked - 39%
Within 2 hours, and with no use at all that was down at 8%. In order to avoid the charge issue i cut my losses and turned it off at that point. Once home (oh, about 4 hours later maybe) I was unable to turn it back on. I then left it plugged in overnight, and was still unable to turn it on this morning until i'd done my cross-phone charging trick.
I'm now entirely convinced there's some form of hardware issue at fault here, so i'm wondering if anyone else has had the same problem with this phone before? I see lots of thread regarding poor battery life, but most seem to be solved by turning data off or some rouge app, neither of which are an issue in this case. Also, any hints for making my life easier when I phone HTC tomorrow? I've read elsewhere their support might not be all it should be.
Thanks in advance for any help! I've ready to pull my hair out as what is a fantastic phone otherwise has been completely ruined by this battery issue.
I think you should get a new battery to rule out that the battery itself isn't a problem. I had similar issues with my G1 a while back and it solved a lot of wierd, seemingly unrelated problems. Batteries are pretty cheap online, $15 or so and some are free shipping.
The way that I figured out my battery was toast was by comparing it to other batteries. it had a bulge in the center where it should have been flat. Fingers crossed it isn't hardware.
had already tried a diff battery (did you know you can chew a corner off a touch pro 2 battery and make it fit??) Which i know worked fine in the old nicked dz and imo as i was getting same issue ruled out battery problem.
anyway... phone has now been returned and i'm waiting 2-3 weeks to get it repaired under warranty (though am hoping for complete replacement obviously)
Chewing on batteries has got to get you extra xda brownie points. I'll remember that

I'd like to think there was some techincal or engineering skill in there somewhere.
but it was mostly "Well, apart form this nugget of plastic they're the same shape..."
I'm having the exact same problem... When you take you shutdown to recharge a dead battery, does it sometimes try to turn back on? I left my apartment like 30m ago with 100% battery, and I'm at 84% and declining. There's nothing running. And I've replaced the battery, same issue.
I think I might just RMA this one.. seems like an engineering issues.
Edit: I'm the 40 seconds it took me to type this, battery dropped to 82%.
Wanted to bump this post. I've since wiped / reloaded and wiped battery stats. It's still jacked. I think it's an internal electrical thing. Reason is: I'll power down to take the battery out. When I put the other one in, it'll turn back on. Or if I power down to charge, it'll turn back on - plugged in or not. I don't want to deal with the RMA process again, but I think it's my only choice. I've taken two phone calls this AM @ 100%, and it's at 96% now. Drives me insane. Ugh... I'll call TMO. Anyone know if the replacements are still rootable?
So... I had my phone replaced, and it's still doing the horrid battery thing. Flashed CM 7.1 RC3 or w/e the latest is, cycled one battery - and it drops like a stone. I have two chargers (one at work, one at home) and they both charge the phone up to 100%. But it's still losing battery life quicker than I'd like. I used to be able to get a good 18 hours out of this phone. Even with a new battery and a new phone, it's acting up. I'll try to flash an older ROM and see if it's the same thing. I updated to #130 nightly from 7/10. We'll see how it lasts today. But I do remember I had horrible luck with CM's ROM's on my G1. Battery would just drain for no reason. The main process taking up the most battery life is "Cell standby" so I changed to the latest radio - and it still drops. OP - have you figured out your problem? I've removed a ton of apps, and it's still messing up. I listen to music for... 45m in the AM, and I get down to 54%. I've formatted my SD Card as well.. it's driving me insane.
I just flashed CM 7.1 a few days ago and while the ROM is great, it does seem to be a litter harder on my battery than 6.1 was. With light/moderate usage yesterday, I got about 16 hours and that was running the battery almost completely dead. With heavy usage, I get about 10 hours and need a bump charge in the afternoon.
You might want to look into getting a Mugen 1800mah battery. You can get them on Ebay from 35-40 dollars. The seller 'nakedcellphone' is based out of Southern California and another user has confirmed ordering from them and getting a legitimate battery (lots of fakes on Ebay). Either that, or carry a charger with you...
Have you tried using Watchdog to see if there are any 'rogue' apps that are causing the drain by running in the background? What about going to spare parts > battery history > Partial Wake usage? There it will show apps that are draining your battery when you're not 'actively' using your phone. For me, the Android System is the highest drain in that menu. Good luck! Hope some of this helps!
I just checked spare parts, and there's nothing too odd in there. Just my music app. And I've changed that too - thought Winamp was killing me. I'll check Watchdog. This is a brand new OEM battery along with an RMA'd G2. It has to be the OS / Radio or something. I've stripped like every non-essential app too.
Hello,
I know, I know, there are many threads on the battery issue. But I'm struggling just too hard with this. I've researched and read every thread on xda and other forums elsewhere to glean as many tips as possible which has certainly helped, but something just doesn't seem right.
Currently I'm using a battery saver app - Easy Battery - which does help considerably during idling and off-use periods - the DINC at least has some charge left to make a few calls and check voicemail when I'm finished on the job site and going home, but when actually using the device it seems like I can just watch the battery drain down - it's really disheartening.
My device details are below. I'm using the best performing kernel I've found after much trial and research. I've deleted about 10 - 14 resident system apps to improve performance - the DINC is as bareboned as it can get. Maybe I can delete a few others still.
I understand JB is more of a battery drain, but can it be this bad? After a full night's charge, I wake up and check my mail in bed, some quick online news browsing, looked at one or two video clips, 5-10 minutes each. I spent about 20 minutes on the phone. Looking at my screenshot, the battery's drained 40%, IN 37 MINUTES!!!
Also, some hours of the day the battery life seems better...? Sometimes I can perform general tasks on the phone, watch a few video clips, do some reading for an hour straight sitting over a pint and there seems to be comparatively little drain at all, certainly not 40% worth of battery drain in a half hour. I just don't get it.
Am I need of a new battery? Is there a super battery for the DINC? Should I be limiting the number of 'recent apps' in the Recent Apps switcher? Is there another Performance setting I'm overlooking? I/O scheduler setting?
Please, please, what can I do - any additional tips would be greatly appreciated. I love the DINC. For me, it's the perfect sized phone that I like, outside of any device functionality at all. Maybe I'm moving on though. Ugh.

if you have the original Dinc 1400 mah battery, maybe your battery just doesn;t hold a charge anymore.
what I do is I don;t even charge my batteries in the phone really. i find that when I charge the battery in the phone, the battery drains quicker. I bought an universal external charger and rotate a couple of 3500 mah batteries after running them down completely. I carry a spare with me if I need but usually my phone lasts into the next day.
you can get 3500 mah batteries for about 5$ or so on eBay(last I checked). the universal charger goes for 9.99 on NewEgg or Amazon. good investment
What I've done on CM10 to try to extend battery life:
Keep my screen locked at 25% brightness but can toggle into 100% or auto when necessary. On CM9 (before I was crack-flashing CM10) I played with auto-brightness levels that were discussed in this thread and they did help. 'Auto' is normally too bright for me, anyways.
Turned off background location reporting in Maps. This will neuter some things in Google Now, tho. You can see how often your phone "checks in" here.
I used SmartAssV2 on CM9 but went to interactive on CM10. No quantitative data that it helped battery life, but it passed my eyeball test after a week+ on both. My phone is flaky on under/overclock so I keep it at 245/998.
I leave 3G on, WIFI on, GPS off, BT off 99% of the time.
Hmm, great suggestions. An external charger(though I'd prefer not to be regularly opening the casing, I'll look into it); 3G radio off; locking brightness at 25%, toggling when necessary; background reporting off. I'll also keep experimenting with a governor and try a week on interactive. A really great kernels guide: http://forum.xda-developers.com/showthread.php?t=1369817.
I have a spare original battery so I've got that in and giving it a powered-off charge. See how that does on top of other adjustments.
BTW Both batteries I own are model BTR6300B 3.7VDC -- 1300mAh 4.81Whr - tekweezle mentioned a 1400mAh battery and other available batteries that are at 3500 mAh now - I guess I'm looking into new batteries as well -
cheers for the responses -
I recommend just getting a new battery on ebay for 5$. Also get juicedefender it doubles my battery life. Also try tiny/pons cm10 rom that has great battery life.
Definitely getting a new battery; I'm already using tiny's rom which continues Pons' CM10 rom builds. Really great -
cheers
Obviously, if you are using your phone non stop, you'd be lucky to get 6-8 hrs of usage. But the true indicator of what a phone does is how often you don't have to be attached to a wall outlet or hunting for one.
I don't know if others get similar results as me but this is more or less typical of me with light to moderate usage-checking email, Facebook, some Web browsing, occasional phone call or text message plus leaving my phone on overnight in stand by.
By the way, how I am on pons/tiny 12-9-12 and working well.

btw, this is the external battery charger I am using. awesome thing is that it charges at 600 mah so my 3500 mah batteries charge up in 4-5 hrs or so. since it has moving pins, you will be able to use this to charge any flat battery for any cell phone or camera you might buy in the future.
the SEIDO HTC EVO modified one I got on ebay charges at 500 mah and for some reason it takes 8-11 hours to charge a battery and I am finding out now that it doesn;t even charge them completely even when it thinks they are completely charged. i take a battery that is charged in this and put it in my other charger and still needs charging of about 10 percent!

I get something similar, probably a little worse, in send/recv about 50-100 texts a day and checking 2 gmail and 1 exchange account constantly. My battery does tank when I'm actively using the phone and really all I can do there is manage the brightness of the screen. I've been doing my tweaking to try to increase battery life when I'm not using the phone. In 7 hours last night it only went down 3%. When I first started using JB it was 10-12% a night.
Great, great info - love these forums, and I love android!
tekweezle - could you tell me exactly which 3500 mah battery you're using with your DINC? Also - no issues whatsoever with the pons/tiny 12-9-12? I thought I saw a few things reported with the 11-28-12 and stayed away from it, staying with the 11-25-12.
cheers!
i have an expensive SEIDO battery that I bought from Amazon in the beginning for about 59$. Never thought the capacity was all that great till i found out that my battery wasn;t even being charged completely. not really worth the money but at the time, it was all that was available

The others, i just bought generic flavor of the day batteries off of eBay for 5$ each. basically throw away items. just search for HTC 3500 mah Incredible battery and you should get some hits.

no real operational issues yet with 12-09-12 Rom. minor annoyances with video playback. actually, the still camera works fine but video camera doesn't save files.
