I've been using CyanogenMOD 7 and love it (mostly). The one thing I don’t like about it is the short battery life. I'm kind of new to rooting phones so it took me a bit to get it rooted and get CM7 rolling. I was wondering if there are any mods out there like CM7 that have better battery life? Or if there's any thing I can add to CM7 to give it more batter life?
I've been using android since the first phone came out so I’m already knowledgeable in what to turn off to try and extend the battery life, but I have noticed a big decrees in batter since installing CM7.
Thanks for the help guys

You can under clock the processor when your phone is asleep. This creates better battery life.

your phone automatically underclocks your processor when it sleeps (for most CPU governors), you do not need to tell it to do so.
I'm not picking on you fyi, I'm just making sure we are giving people accurate information... there's only one thing worse than no information: incorrect/incomplete information.
op: which version of CM7 are you running? remember, the more minimal your setup (ie less homescreens, less widgets, manual syncing of gmail and whatever else, etc) the better your battery life will be. this is especially true of newer phones that are getting heftier cpu & gpus that, while intelligent with power consumption, are going to drain even larger capacity batteries relatively quick with moderate/heavy usage.
how long are we talking with battery life? how heavy a user are you? for reference, I get around 16 hours of battery life if I don't charge the phone at all from unplugging to battery dying with moderate to heavy usage (texting ~50 times a day, sometimes up to 100 emails depending on what's happening at work, couple hours of calls, couple hours of streaming music [pandora or audiogalaxy], couple of hours of games [peggle and plants v zombies mostly - both of which are resource hogs], etc).
I have just learned to get used to the fact that the phone is going to die if I use it a lot, so I've purchased three micro-usb cables and a car charger.. that way, unless I'm in an area where there is no charge-capable usb port nearby, I'm always able to get a little more juice if need be.

but i also mean setting the max sleep to 368mhz. by default its set at 800mhz. sometimes with apps running in the background, the processor may go to 800mhz without you knowing
check out 'powersave' and set your cpu max to 806mhz. should last you a nice long time like that. responsiveness suffers, of course.
'ondemand' and 806mhz is the best comprimise for me. still fine with HDvideo recording, streaming audio, Nav, etc
if you really want to make it last... clock down to 400mhz, turn off all the sync, set brightness and timeout to minimum, all the radios off (airplane mode), and the volume down, on vibrate.

But some govenors don't drop the sleep to the lowest profile. In fact almost all keep it above the lowest clock. Other kernels allow it and you can also use third party to set it lower. When the tweaKr script becomes universal it will be even better =)

It suffers in powersave because it stays at the lowest setting only. No reason to set to 806. Lol and that bottom comment is hella funny =), but if he does that his phone will just be...a waste of pocket space.
Your best bet is to do some research on kernels. If you are using cm7 to cm 7.0.3 id recommened pyros kernel. If you are on 7.1 or a nightly over 121 I believe id go with eugene's streamline5. It did wonders for mine Also there is a battery saving tips. Google G2 battery saving tips. Should be first link that comes up.
Cyanogenmod roms are known to be battery hungry. Nom nom nom.

Do you have link for this? I'm running 7.0.3.. but I dont think im finding the correct Kernal.
Mugen 3600mah = better battery life...
Can you elaborate on what kind of battery life you are getting now? How many hours, and for what level of usage?
How long have you been on CM? It takes a couple charge cycles of the battery after flash any ROM, for the battery meter to be accurate. Clear battery stats (as mentioned) then charge to 100%, let drain to about 20%, repeat a couple times. Don't drain until the phone dies. Some people say to do this, and its not good advice. Over discharge of Li ion batteries can cause them to no longer take a charge. There are people on here, on the Vision and other phones, that let their battery drain to empty, then the phone would no longer boot, forcing them to replace the battery.

Hi all,
As title I am struggling to get to even three hours screen time in my average day. The screen on use is generally web browsing (hsdpa), forums, Facebook etc so no intense gaming.
Have checked bbs and cpuspy and no strange drain present (screen off drain is actually excellent.)
Having seen some of the screen on times achievable I wondered why I am unable to get the same. I have tried lowering auto brightness values dramatically, underclocking and golfing CPU and gpu, different roms and kernels and have still yet to break the elusive 3 hour barrier.
I suppose my main question is whether some batteries are plain bad, or whether some screens simply consume more power than others.
If anyone has any insight, or other things I could try to boost my battery, it would be very much appreciated.

Go in to settings > battery and see what's eating your CPU
My phone is at full brightness, and I am 14 hours on battery with tons of screen on time (3g on, no wifi, some browsing, app downloads, playing draw something) and my battery is at 45%
perhaps a tablet with a sim card will help with your battery woes, and maybe eye sight in the future
So I switched from the iphone with edge to the Tmo S2 with Jugg 5.0 ROM + Go Launcher. I really appreciate the 4g speed. However, the overall experience is not as smooth as the iphone and the battery life sucks big time. I normally have to constantly plug the phone in whenever I can. It works ok when I'm at work but when I'm out all day my battery won't last more than half a day. It's so bad to the extent that I have to turn off my phone and turn on when I need to call or text so I can keep the phone alive the whole day. I tried Juice Defender but it didn't help my battery at all.
Yesterday I spent a few hours on XDA and I came up with these solution to my battery problem:
+DarkSide Digital Warfare v2.7 ROM (couldn't find 2.5.1 version)
+Flash Synergy Kernel over (supposed to give better battery)
+SetCPU app (auto detection)
+Zeam launcher
So far, it seems to be better on the battery. Is there anything else I could add to make my battery last longer? I need the phone to last at least the whole day without charge. I'm constantly on 4g looking up stocks, reading news, email, google voice, grooveip, facebook, turn by turn navigation, music, netflix, youtube ...
Thanks,
Welcome to Android.
From what it appears, you seem to be a heavy user. The most you can get out of a Android device with heavy usage is 3/4 of a day (14-18hrs) tops.
You have 2 choices, either you travel with the power cord not to far away and plug it when you need it or you invest a whooping 10$ and buy another battery.
There are tricks to keeping your battery healthy but lasting all day as a heavy user will be very difficult.
If this is a new phone it takes a week or so for the battery to settle in a hold a charge well. After a week or so you'll notice your battery is lasting longer. Also make sure that nothing is keeping your phone awake 100%. Some apps don't play nice and cause issues. Welcome to Android.
Note: navigation kills battery fast, when your using it try to plug into a car charger or something.

There are a lot of things you can do to improve battery.
1. Juice Defender (which you say you have already tried)
2. Limit the number of widgets you run or run no widgets like I do
3. Turn the screen brightness down all the way
4. Don't use Live Wallpaper, also, try to pick a dark coloured wallpaper since white/light colours seem to use up more battery.
5. Uninstall apps you don't use.
6. Turn off GPS unless you need to use it.
7. Turn off sync completely or only have your gmail sync. I don't need to be notified when I get a facebook message so I don't need it syncing every few minutes or every hour, I can check that manually myself.
8. Turn off animations.
9. Close background apps that are running that you aren't using.
10. Use Task Manager to close open apps when you are done using it. Task Manger is your friend.
11. Enable Power Saver Mode.
etc etc.
Those are the main things that I tend to do. I plug my phone in every night before I go to bed as well so I am not sure how long my battery actually lasts. But typically after 16hrs of use I still have 60% battery when I go to bed.
Currently my phone has been on for 7hrs 15mins and I have 87% battery. So you can do the math. I am not as heavy a user as you seem to be, but hope this helps. Peace.
Check out this video it helps show you how to save battery. Enjoy!
Thanks for the inputs guys. I should have said I was looking for Rom/Mod/Scripts/Apps... that can be flashed onto the rooted phone. I have done all the basic battery saving housekeepings as listed by Chochiwpg.

I'm up 5hr 45mins on battery and my battery is at 41%. Let's see if it will last for today. I will put Juice Defender in tonight to test out the battery tomorrow.

You could run Juggernaut with Faux Kernel and Gideon's battery scripts. Or Telus T989D stock ROM lightly tweaked with same kernel and script. Got good results on those as well. Good luck.
Btw, has anyone had tremendous increase in battery life using the after market extended battery?

If you are talking about extended batteries that don't require a custom enlarged back cover, you will not get the battery increase that you are looking for, not even close. I cannot speak for the heavy duty ones that require an enlarged back as I do not own one
Gideon's scripts are great with Juggs. Underclock it as well like 384-1080 is a great setting. Also let die all the way down and charge all the way up and repeat for a few cycles. And don't stare at your phone every few seconds either lol! Another thing are the notification lighting buttons at the bottom. Drop to 1.5 seconds.

I have the extended 3800mah battery. It's insanely fat and makes the phone look hideous. On top of that I really don't feel like the battery lasts all that long at all. It's in my pocket all day at school and by 3:30 I'm at 35%. This thing cost me 65$. Total ripoff. I'd suggest spending 20$ and buying two more regular batteries. See what that does for you all

A few things you can do on ANY ROM to improve battery life.
*) Decrease screen timeout to the lowest possible setting.
*) Adjust screen brightness to the lowest level you can tolerate.
*) Decrease the backlight key timeout to the lowest setting ( or off if you have the option )
*) Be sure to only have wifi and gps on if you are using them.
Those will help quite a bit in general however, a ROM like Juggs is meant to really take advantage of the power of your device so its probably wise to move to a different one if max battery is your goal. I love Juggs but had to move on to the AOSP stuff. Also, heed the advice above, allow the ROM a few days to "settle" before making a switch or even a judgement of its performance.
Thanks for the replies guys. So my phone lasted for 9hrs today which is a little bit of improvement. I was streaming netflix for half an hr on the train on the way back home so that may have drained the battery. I have just installed JD, will post back how it goes tomorrow.
So the extended battery is a no go eh. I really don't want to lug around a few extra batteries. I want to carry as little as possible. I normally carry my phone and my ipad but now I tend to not use the ipad much now because the S2 screen is pretty gigantic for a phone.

I know the point was already made but just to reiterate, you can get 2 Anker extended batteries (same size as regular battery) and a universal charger for like $20. This will leave you with three batteries. One for the charger, one for the pocket, and one for the phone. With this system its pretty easy to always have one full battery ready to go and one charging. The battery is small and can just go in your pocket, or maybe even in your wallet depending on your preferences. It solves the problem completely. I don't think you are going to do much better because if you are a heavy user then your battery is going to be used because your phone isn't going to be sleeping.
Good luck.

If you read my post above. I'm against the idea lugging around too many things. It's also a hassle to swap the battery and keep them all charged. I may be a heavy user but it's not like I use the phone all the time. I use the phone heavily early in the morning on the way to work and after 5pm on the way home after work. The commute each way is roughly 45 mins. In between the commutes i make a few calls and texts through GV. I don't think i'm that of a really heavy user.
Anyway, it's noon and I'm at 75% with JD on and setCPU to 384-1084mhz which is pretty promising.
Questions go in the Q&A section
Since you changed kernals, you aren't going to benefit from TDJ's battsaver script you can use with the stock 2.7 kernal.
Go lower on the max frequency. Something below 800 mhz. Setting a negative gloval mV doesn't hurt, and if you can get to -62.5, that's great.
Oh, and when using data, try GSM only...
To be honest, the larger problem with battery life is typically the user. There's no real magic on making the phone last longer other than using it less. If you're going to be power using the hell out of it by using 4g for hours streaming media, your battery is going to be ****.

Don't you think it is ironic for me to switch from the iphone to the S2 because I couldn't stand the slow 2g Edge connection then have to lower data speed to GSM (2g) just so I can use the S2 long enough?
I think the S2 is one heck of a device but the OS and Apps are not running very efficiently.
I tried the ICS ROM ARKSIDE.UCLE2:: x[BETA07.1] in the last 2 days with setCPU at 384-1026Mhz. I have had great battery life. I got home at 12 am yesterday with a 2% battery. Today it's been 7 hrs on battery and my battery is at 70%. I don't know if it is the ROM, setCPU or a combination of the two but I'm pretty happy with the phone right now. ICS is awesome too.
I highly recommend that solution to anyone having a short battery life problem with their S2.
It is a little ironic since you did bring up the comparison. What I was attempting to do was to bring the phone more into spec of an iphone to get similar battery life. You're probably going to even get better runtimes due to the battery having a much larger capacity and better screen technology. All that superior hardware packed in the t989 is going to need more juice to run.
It's great you're getting good runtimes now. From my personal experience, once I drop down to the single digit percentages, it starts lasting a lot longer per percent. If you wanted to squeeze all you can from the device, those 2000mah aftermarket cells might add another 15~30 minutes.
All,
In case you haven't noticed, the battery life of the Nitro HD is kinda bad... Then, when you add ICS into the mix, it gets worse.
When i first flashed the Leaked ICS ROM, I noticed that I was only getting about 8 to 9 hours of battery life with very light use. So, I endeavored to find a way to extend that time without buying an expensive extended battery.
Here are my findings:
GPS
Settings > Location Services
Now we all like the convenience of being able to pull out our phone and find the nearest gas station or fine dining experience. But when you think about it, in our day to day lives, we don't need directions that much.
GPS and Location Services are huge data and energy hogs. If you have ever seen how much can go on in the background when it comes to Location Services, you would cringe. So, set up your GPS like the screenshot below and you will see a little battery life improvement and data usage go down.
Display Brightness
Settings > Display > Brightness
On my Nitro, the display uses up the most energy by far. So, it only makes sense to lower the brightness a bit to save power.
Developer Options
Settings > Developer Options
The Nitro has a powerful 1.5GHz CPU which uses a ton of energy when in heavy use. Some of you might say, "But Matt, I don't use that many apps that need the CPU." Well, it's not that you use them. It's that the ones you have used are likely still running. For example, even though I always use the 'Exit' menu item in Slacker Radio, it will always show up as a running process in Task Manager.
In the Developer Options, there are a few useful ways to fix this problem.
First, check the box next to 'Don't keep activities'. This will cause whatever app you are using to stop completely as soon as it is not on the screen anymore. This is useful if you have the habit of using the 'Home' button when you are done with apps.
Next, set the 'Background process limit' to something other than the standard limit. I have mine set to 4 processes. This will keep processes that are not tied to any specific app in check.
If you use a lot of apps and games that have to render video, it might be a good idea to check the 'Force GPU rendering' box. This will force apps such as games to use the slightly less powerful GPU in the Nitro for video. Thus letting your CPU relax a bit. I have also noticed that heat doesn't build up as much with this box checked.
Lastly, if you want to know about more of the processes that hang in the background that may cause performance issues, you can check the 'Show all ANRs' box. Personally, I found it annoying.
Power Saver
Settings > Power Saver
I was really excited for this feature but also very skeptical. But, I gave it a try anyway. What this feature does is when your battery level gets to a certain percent that you choose, it will turn off power consuming features and change some settings to use less power. I have mine set to engage at 20% battery life.
The tips I have seen say to check every box. But, because of my profession, I have to have 'Auto-sync' left on for emails and such.
With the settings below, I usually see the last 20% of battery last about 4 to 5 hours of medium use.
CPU Clock
*Requires Root*
Unlike all the tips above, this one will require you to root your Nitro.
As I said before, the 1.5GHz CPU uses a ton of power. When you think about it, unless you are playing games all the time or doing some kind of complex calculation as part of your Quantum Physics experiment on you phone, you really don't need all that power. So, what I did was underclocked the CPU to 1GHZ. This gives me the power I need to do what I do but with more efficient energy consumption.
I used SetCPU for this but there are a few other choices out there that do the job just as good.
As you can see from the screenshot below, I have set the max frequency to 1026MHz and the min frequency to 384MHz (I have since set min to 192MHz). I set the governor to 'conservative' based on this post: LINK. But, I think that any of them will help in different ways.
If you are curious, I'm also inserting a screenshot of my benchmarks after the underclock.
CPU Sleep (Suggested by rani9990)
*Requires Root*
XDA user rani9990 suggested an app called CPU Sleeper that, essentially, puts additional cores into an offline mode while the screen is off.
I can see how this would be advantageous because when your phone is in sleep mode, it really doesn't need all that extra power.
I have had it on my phone since i got up this morning and have noticed a significant jump in battery life already.
Results
Before these tips, I was getting about 8 to 9 hours of medium use on a charge.
After, I get roughly 15 to 20 hours of medium use. (It varies from day to day but hovers between 15 and 20.)
If anybody has any other tips, please let me know so I can add them to the list.
You should also tell people to get CPU sleeper (root) saves tons of battery life for me.
Also, disabling haptic feedback saves battery.

Sadly, battery life on this phone really sucks even with the optimizations. having compared both, I can say that the Nitro HD with optimizations and 3800 mAh Hyperion battery gets about the same battery life as a Galaxy Nexus on the stock ROM and stock battery.

Perhaps check your running processes. With these tweaks in place, I unplugged my Nitro at 7:45is this morning and right now, at 2:15pm, I have 79% battery left and I've made two 15 to 20 minute phone calls and rebooted about 6 times because of some testing I've been doing for another thread.
Also, the Nitro does have a faster CPU that would take more power than the Nexus.
I have done all of this, in addition to in Settings/Wireless & networks there's "more..." click that and theres "Mobile networks".. and the option for "Use only 2g networks" I'm using that for only texting while at work and doing pretty decent with battery life. since 5:45 to now 10AM texting all throughout that time I'm at 85% battery.

Uhmm.. maybe its a CM9 only feature.. sorry hijacking then.
i found many of these settings are available in cm9 and after making the changes, it appears to me they work very well. thanks again eh.
UPDATE: I refrained from plugging in my phone all day yesterday and got 14 hours and 32 minutes of medium to heavy use.
Sent/Recieved 191 text messages.
Spent 2 hours and 47 minutes on the phone.
Updated 7 apps from the Play Store.
Played Dead Space for roughly 35 minutes.
Checked Facebook 3 or 4 times.
Read a news article online.
I think the battery did pretty good this time around.
Thanks for helpful tips!
The only problem I got is that the screen turned to back (with music still on) when I started NinjaJump with "Force GPU rendering'" checked.
You don't want force GPU rendering checked...

Display Brightness
Settings > Display > Brightness
On my Nitro, the display uses up the most energy by far. So, it only makes sense to lower the brightness a bit to save power

What I`ve noticed is that when I set Brightness to 100% I have 3...3,5 hours of wake working screen active time before battery exhausted. It's on ICS leak V18F. But if I set brightness to 30% or "auto" mode I got about 2....2,5max hours of screen active, it exhausts quicker
And secondly, on CM9 it helps me to check off "surface dithering" in 'performance' options. But on official ROMs we haven't this option available to tweak
I found that JuiceDefender has seriously saved me a whole lotta battery. Like seriously. I was getting 12 hours of medium to heavy usage before, and now i can hit 30 hours of medium usage. Then again, Data isn't turned on for me, I use the phone for Wifi and Calling.

JuiceDefender saved me tons of battery also. But I noticed that it was always waking my phone up for a second at random times. Have you had that issue at all?

Nope, but I don't look at my phone every waking second. Maybe it did do it. But I'm getting a serious boost in battery life so I don't really care.

For me keeping the wifi on (and thus connecting via wifi both at home and in the office) allows me to save battery..
To me it seems strange, because my old phone literally sucked battery while keeping wifi on, but on the nitro wifi consumes less than hsdpa data transfer.
I've added a link to my SetCPU Profiles file in the guide.

Both stock and CM9 RC2 are disappointing: 250 and 328 respectively. I've applied the suggestions here and don't know if I'm doing something wrong.
I was rather happy with my phone with GB managed by Battery Defender from Infolife. I used to have 1,5 day with "Mostly Idle" usage. Now after upgrade to ICS I just got 10% down per hour on idle. So disappointed. I'll play with your settings a while. May be Battery Defender uninstall/reinstall can help 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.
