I have been looking through forum after forum about the battery life on this rom, it has been dropping 1 percent every 2 minutes or so and is about to be dead. Does this sound like a battery problem or should i just recondition it. I just wanna know whether to buy a new battery, get a new rom or what?
Ive been having the same problem, ive already tryed the reconditioning process but i still lose battery very fast. But the only time i dont lose alot is when its on standby.
my battery is outstanding on v3. Id reset and and try again, or check your apps, something has to be up. :u

I think he means go into recovery and clean cache and dalvik cache. Maybe even do a factory reset (however that will clear out your applications). Just make sure you have good backups before doing a factory reset.
That never hurts to odin back to stock just to rule out the ghosts and goblins. to me, it sounds like an app issue. How many widgets are you using that need to refresh? How many programs are open and active when you first start your phone? Are you using a task killer? Are you actually using the phone actively, or is it on "standby"? Answer a few of these to give us a better picture of your usage.
My battery life has been stellar.

thanks for the wonderful help and awesome insight..
Mine has been pretty good... I would recommend what swehes said.
I got pretty good standby time, but when I use the phone (such as calling, browsing web), battery drains super fast. I can have it last more than 4 days with light usage, but less than 10 hours with normal usage (no games, only texting, calling and browsing web).
Either do the process people are calling "recondition your battery" (charge fully, drain fully, charge fully, then immediately wipe your battery stats), or charge your battery fully once on an external stand-alone charger, then wipe your battery stats.
The battery profile in the stats file with the ROM just doesn't match your real battery's performance characteristics -- low charge point, high charge point, usage curves, etc. ... so it thinks it has juice when it doesn't, or it may shut down when you should still have juice left, etc.
My battery life has improved with every day. At first, when I cleared the battery stats in CWR, the phone lasted me around 36 hours. However, the day after it could not hold for more than 16 hours, but it has been increasing and now stays around 26 hours with my moderate to heavy use.
EDIT: Freezing Media Hub and the device management service in TB has definitely contributed to the prolonged battery life, I should probably remove it all together.

If you use Titanium Backup (I highly recommend spending ~$5.00 for a full Pro version) you can freeze the apps via the Batch operation.

Is this safe to freeze both media hub and device management?
Well i just conditioned my battery and that didnt help. So i'll try wiping the caches and then if that doesnt work then i will odin back to stock and fresh install it.
And i only have weather, the messaging widget that tells me how many messages i have and thats about it

reconditioning the battery is good to do but only gives a minor difference in how long it takes to drain. I already know it's an app problem. Open you're settings, go to applications, and select running services. What do you see?
Could it be device management?

***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

NOTE: I did edit his post to make it a little more clear. I'm slightly anal retentive that way.
HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.
Samerhing happens to me... and I just took it off the charger and I'm on 96 percent in less than 1 min

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

If I go to Battery History and change the top dropdown to Partial Wake Usage, it says Android System at the top with a bar that's at least 75% full.

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.

I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

try disabling gps in the notifications, that worked for me, but once i turn gps on again, it will drive up to a high percentage.
Here is something I just noticed I sometimes wipe my battery stats once I get a full charge on a new rom. I always wipe and flash using fastboot boot recovery.img.
Roms always run fine smooth no issues. But for some reason if I go and wipe my battery stats after a full charge my gauge will lock up and the battery chart doesn't work anymore...
Even a reflash and wipe doesn't help. What would cause this issue?
Im on hboot 1.5
I know back when I would just flash the boot.img then the rom.. I never had issues wipeing my battery stats....
So anyone else have this issue?
I know folks say you don't need to but some times you do need to if you flash a rom and for some reason your battery gauge sticks at 99% green light... Will never hit 100%..
it eventually will hit 100%... you have to charge it while the phone is off just once and it will green light while off... then boot up and charge again and it will hit 100...
also, what exactly do you mean by the battery chart??
it shouldn't have an issue because your voltage/charge is monitored by the kernel... kind of an odd little anomaly to be honest.

here's the thing, the reason why you are not seeing anything in your battery usage is because that's exactly what the batterystats.bin file is - it is a data dump of statistics... what has been using your battery, for how long, all kinds of mathematical outputs of screen on usage, awake time, apps, so on and so forth... converts all of that into a percentage and that's what you are seeing in your settings/battery usage.
so, accordingly, when you delete batterystats.bin, all of those statistics are gone and you have nothing to display. after a charge cycle or so, you will see that information displayed again.
again, batterystats.bin is simply the statistics of what has been using the battery. has nothing to do with the phone's actually ability to display the correct percentage, get a full charge, etc... that is ALL the Linux kernel which is your power management for the device.
wiping batterystats is truly unnecessary. does nothing for your battery life, and flashing a ROM then wiping battery stats is useless too because when you flash a ROM you wipe data... and the batterystats.bin is found in /data/system... so effectively you are wiping battery stats every time you flash a ROM.
but to go back to the OP... not sure why your percentage is not being displayed correctly... sounds like a ROM issue.

Ya I pulled the battery let the phone discharge and put it back in finally got everything working again ... I was on nightlys a few days ago and flashed one last night that was when I had some funky issues with the battery gauge after doing a wipe.
I only do a wipe if the gauge gets dicked up...
Anyways thanks man... Hopefully I fixed this sucker...
yeah, definitely was a ROM issue...
hope it's worked out and no problem man. hope all that rambling made sense, haha.

Charge to full, boot into CWM and wipe battery stats.
Use until device dies from dead battery, recharge to 100%. Use as normal for a couple days. It should get better.

myth
maybe a myth and from everything i have read (that article included) it seems to be. but im ok with the placebo affect or whatever bc i at least FEEL like it has helped since i did it after getting on cm9 beta 0.2.0 or whatev. not on beta 0.3 battery has been sucked hard as all get out, but such is life.
I have a question/comment about this. When a ROM is flashed I always wipe and format /data, /system, /cache, /davlik-cache, and factory reset. At this time I power down and recharge although the recharge may not matter as the lowest I've been was 85%. After recharge I boot into CWM and wipe/factory reset again then allow the phone to reboot. Isn't the batterystats.bin file in one of those places I wiped/formatted?
Once it's booted I just turn off and power up again then activate. Out of all the different ROMs I have tried this usually works very well. There was only one time my battery life was poor after flashing and I tried a battery wipe app and it still didn't help. I finally attributed it to the ROM and flashed a different one. Following the same process the new ROM was installed and battery life is great again. Did this yesterday flashing Rocko unlocked 3.0. After 4 to 4-1/2 hours of heavy use, when I say heavy I mean heavy, I am still at nearly 70% battery. If it works the way it looks to, I'll be getting at least 10-12 hours on a charge, probably more.

Calibration
So what you are saying since I have a Photon with an extended battery even rooting it won't calibrate the battery. It sits at 1% for hours. Had an HTC prior and didn't have this problem. Waste of money getting an extended battery when you don't know when it is going to die on you.

Not at all. What I'm saying is I personally don't use ine as I wipe battery stats as part of ny flashing process and do my first boot on a new rom with my battery at 100%. That works for me.
If you're switching to an extended battery you may need to wipe battery stats. This can be done with a battery calibration app or from within CWM, if you've unlocked and installed a custom recovery.
BTW: Rooting will allow you to install and run a batt cal app but rooting alone will not calibrate your battery.

So I will be learning more about rooting. But I thought i saw where others who had extended batteries that rooted with calibration apps their Photon still didn't read correctly. I could be misunderstanding something. Newbie here.
I've been flashing left and right trying to find a ROM worth sticking with. And my battery is being abused big time. Percentage after percentage with just texting and things. Does anyone have any suggestions on cm10 ROMs or other ROMs that have the theme manger option that don't eat up the battery? And I know that wiping battery stats in cwm is helpful but I wanna refresh my battery. Can I have some help? Thanks

Try sticking to one ROM for a few days. Typically takes a few charging cycles to settle in. Also, if you can let it drain down fairly low then let it charge completely before taking off the charger for a few days. This will usually get the ROM and battery to sink better together.
