I decided to do an experiment this morning. My fiance and I both have Dincs. We're both running SkyRaider 2.0.1. We both have the 1500mah touch pro 2 battery. I bump charged both phones this morning and both went off the charger at 8:30. I cleared my battery stats in clockwork immediately after the bump charge. I didn't clear her battery stats. She had been getting better battery life largely because I use my phone a lot more than she does. That changed today.
The numbers don't lie...
---------------------------------------------------------------
my phone - battery bump charged and battery stats wiped:
8/3 - off charger: 8:30am
Stats @ 10AM
Uptime: 1.5 hours
Awake: 1.25 hours
% left: 94%
Stats @ 12:30PM
Uptime: 4 hours
Awake: 3.75 hours
% left: 85%
Stats @ 3:45PM
Uptime: 7.25 hours
Awake: 7 hours
% left: 68%
Stats @ 12:30AM
Uptime: 16 hours
Awake: 10.5 hours
% left: 24%
---------------------------------------------------------
Fiance's Phone - Bump Charged, battery stats not wiped:
8/3 - off charger: 8:30am
Stats @ 12:30PM
Uptime: 4 hours
Awake: 1.25 hours
% left: 68%
Stats @ 12:30AM
Uptime: 16 hours
Awake: 7 hours
% left: 12%
----------------------------------------------------------
I've come to the conclusion that wiping your battery stats is a very important thing to do and will give you hours more battery life. I'm currently losing a little over 4% per hour, which should give me 23-25 hours of battery life. This is a very significant improvement over the 14-16 hours that she will likely get.
I do find it really odd however that my Uptime and Awake Time are so close. This would normally lead me to believe that some program isn't letting my phone go to sleep, but my battery life indicates that isn't happening.
----------------------------------------------------------
Day 2: Didn't get rid of need to bump charge. First bump charge actually seemed to take a little longer this morning (over 30 minutes). Second bump was 6 minutes. Had to scrap today since my fiance's phone didn't charge last night. It wasn't plugged into the wall. Doh!
i might give this a try. i'll be interested to see if others try it and see what their results are.
Would I have to clear battery stats every day in order to achieve this additional battery life, or is it only a semi-regular thing?
???
How do you wipe them in clockwork?
Question- did you fully charge, wipe, then drain battery down /all the way/ before re-charging (e.g. phone shuts itself down) or did you charge, wipe, and then let it drain a bit and then just plug it back in the charger at night without letting it shut itself down from lack of battery?
Thanks.
I just tried this earlier as well. I bump charged (charged with power off until led went green, booted all the way up, and then powered off, repeated this cycle like 3 times) and then wiped battery stats in clockworkmod (it's in advanced).
Too soon to see if it makes a difference, and I really didn't have any problems but figured longer is better right
Edit: I now plan to let the phone run until it shuts its self off

I doubt it, but don't know for sure yet. I'm tempted to charge it back up now to see if there is a difference in length of time spent bump charging. I hope it shortens it. I won't be clearing either of our stats tomorrow to see if the battery gains comparable to hers stick.

I let it drain itself all the way, then charged it overnight. woke up. bump charged for 1 cycle then cleared the stats.
Doesn't work for me, bump charged this morning then booted to recovery and wiped battery stats. If anything, it appears my battery life is worse and one side effect is I did not have 3g on the first reboot.

Your 3g data drop on reboot has nothing to do with wiping your battery stats. It's a known bug in the 2.2 roms. There's also no way that it could make your battery life worse. You're probably just using more heavily today. It's hard to compare one day to the next since your usage levels vary. I know that I use my phone way more than my fiance and comparing the same phones pulled off the charger at the same time is the only way to tell if it makes a difference.

I didn't have any problems with 3g on the first boot, and my battery life doesn't really appear to have been effected. I can go about a day between charges, and it stayed the same.... completely anecdotal though and I've only been through one charge.
you should clear stats regardless

I know about the 3g bug but I've never encountered it, ever, until I wiped the battery stats. Maybe that's just a coincidence.
Maybe the reboot due to the loss of 3g is what drained the battery more quickly initially. My routine is the same every morning. Unplug the phone, turn on pandora, walk ten minutes to work. So I have a fairly even amount of usage for the first few hours since it sits idle after that.
Maybe I'll revise my initial thoughts to say it may not be worse for the battery but I'm definitely not seeing the improvements you are. Can I ask what ROM you're running?
First Time Bumping
I have had issues on and off since I got my Dinc. Running SkyRaider RC3 atm seems worse since I flashed it.... 2.5 seemed better. Doing a bump charge/wipe now and will post later with results. I am a fairly heavy user (I know 'heavy' is very relative) and know that a whole day (about 8am to 8pm) is pushing it for me, but I am lucky to make it till 12pm. I have actually seen it drop to 20% before 11am. During the first few hours of the day, I may check 2 emails, send no more than 3 txt and make one phone call... Seems like a big drain for that.
Weird, I wiped my battery stats today for the first time and also NEVER had a 3g problem when rebooting. Now EVERY TIME I reboot there isn't 3g untill I turn on and off airplane mode. I know the two doesn't seem to be revenant, but it seems like a lot of people are running into the same exact problem. Anyone care to input on this?
Well later on in the day I tried a restart again the the 3g turned on a few minutes after the phone booted. It still hadn't ever taken this long before, but it did come through on its own. Just a little update on my last post. I'm still interested in knowing why though
Well so far so good, but didn't use it much today. 3G bug happens to me every reboot, but comes on in a few seconds. I'm at 54% atm and bumped/cleared at 2pm est its now 10 pm

If your phone uptime is close or same as the number of hours u have since unplugged, that means it's the usb bug preventing your phone from going to sleep.
What u need to do each time your phone is fully charged (connected to the wall charger or USB cable), u will need to unplug the cable and do a manual reboot.
Otherwise, the phone might still think it is plugged to an external power source and refuse to go to sleep even while your screen is turned off and your phone is idle.
Then u should see using Spare Parts or Battery History App, that your uptime is around 10% to 16% of your total time the phone has been unplugged.
I followed directions on what I thought to be a battery fix, but it ended up making my battery life twice as bad. Actually it takes longer to charge now than it does to drain.
Anyone else have this happen?
Sent from my ADR6300 using XDA App
I did the same thing, but I've only charged once and I didn't time it. I haven't been timing any of my charges or discharges, but maybe give it some more time, that's kind of how stats work isn't it....usage over time? Good luck.
Today I started at 100% (not a powered off full charge though). After 2 hours of moderate use I was down to 50%. I have been charging for an hour via car charger and currently at 67%.

Not to be a dink, but then it would appear that you didn't follow the instructions. As a result, YMMV I guess.
1. You will need to charge the phone to 100% (while the phone is off).
2. Leave charging cable plugged in.
3. Boot into recovery and wipe the battery stats (should be under Advanced).
4. Then boot into Android.
5. Then remove the charging cable.

Give it another shot, and I would suggest that maybe it not be thought of as a "fix". Try using the wall charger as well. I only use the wall charger as I have a converter in my vehicles. Let us know how it goes!

Those are actually the directions that I followed yesterday afternoon. I didn't notice the battery life being any different after doing that initially. At the end of the day I charged my phone via wall charger for roughly 8 hours while I slept.
I was unplugged for less than two hours and watched it drop down 50%. Wifi was off, Gps also off. I was doing some web browsing and also using the xda app. I played a game for a couple of minutes.. That was it. I really should've checked the battery usage but I didn't think of it in time.
I only charged it in the car today out of necessity because of the super quick discharge. When I'm at home I only charge with the wall charger.

I've heard others say they found facebook or twitter running in the background and that when they killed that it made a big difference in battery life. Perhaps that?
WiFi set to never turn off
I noticed this morning that WiFi had been set to never sleep, I just changed that t 15 min.
Had a full 100% charge last night did not leave on the charger, minimal use this morning down to 78%.
Let's see how the new WiFi settings works.

that doesn't do anything unless you leave wifi on all the time, and if you do then that would be one solution to this problem.

I experienced the exact same issue after doing the battery thing yesterday. Tried several different kernals since then - no change: I could just about watch the battery go down. This morning I wiped and loaded SR Sense 2.5.2 and the updated stock kernal from ROM manager. We'll see how it goes...

I did this and just installed 2.5.2. I then installed the Hydra kernel and wiped battery stats when I was at 100% and the unit was off/green light. The battery has gone to crap too. Any ideas?
thats weird, i did wipe battery stats (correctly) at 11 last night. i woke up at 9:30 (lol) with 93% battery left. the phone was sleeping the whole time, but i had sync turned on and had recieved several facebook updates, txts, and emails. now im losing around 10%battery every two hours or so, and i am using the phone to send txts and emails every three to five minutes. so battery life is actually much better. after the cable is unplugged, is it necessary to let the battery die fully, then charge, or can i charge it now? (its at around 30%)
so basically, i was wondering if it is necessary to run your battery fully down after doing a wipe battery stats
I don't know what to tell you guys. Since wiping stats, my phone has been up for 36 consecutive hours with an awake time of 2:40 and the battery is at 30%.
For reference I guess....

Great question. Anyone have any knowledge on this? I didn't let mine discharge all the way.
I do have some kind of update. I had to do a factory wipe today and since I did that my battery life has been much better.

It's completely impossible for wiping your battery stats to make your battery life worse. It's a common misconception that by wiping your battery stats you somehow condition your battery. It's actually quite the opposite, because you're actually conditioning Android by wiping your stats. No matter what your battery percentage or meter says, your battery is still capable of holding a certain amount of electrical charge and your phone will not die until it's fully discharged. On the other hand it *might* make your percentage or battery meter read wrong if you either:
a. wiped your battery stats without a full bump charge (e.g. wiping your stats at 60% charge *might* make your phone think 60%=100% and as a result, you'd see huge decreases. but, you would most likely sit there with a phone showing a 1% charge for hours after it got there.)
b: didn't allow your phone to discharge fully after wiping your stats (same problem as example a, but the inverse of it)
All wiping your battery stats does is delete the file "batterystats.bin" from your /data/system folder. This file is recreated when you boot your phone after wiping them. It keeps the data on what's using your battery for when you click "battery use" in the settings menu. It's also thought to hold the stats that tell you phone what a full charge and no charge feels like and that if you fully bump charge your phone, wipe that battery stats, and then full discharge your phone (without interrupting it by switching ROMs or doing updates) that you will have a more accurate battery meter. It won't eliminate the need to bump charge your phone or make your battery life better. It will just be perceived as better since you won't get 20% drops in your reading in 30 minutes due to a badly calibrated batterystats.bin file. Also, you'll feel better because instead of looking at a 50% reading, you'll be looking at 60%.
Your battery still has the same capacity, charges to the same level, and discharges in the same amount of time. The only thing that can change those things are usage levels.
so should i redo my wipe battery stats then? when i originally did it, i ran it down to around 40%, then rebooted, then i plugged it in around 15%. would this mess it up then?

Do you know how we can see what's inside the actual batterystats.bin file? I tried in root explorer and cannot open in no matter how I try.
i dont care what vantagejuan says, when i tried this process...and did it correctly, my battery was down to 85% within an hour..i know this because i unplugged it when i woke up for work, and i when i clocked in, it was at 85%
it was never this bad, i tried locating the file again from an old backup, but it didnt help...im hoping that like someone else said, a couple cycles through it will get better
im using the skyraider 2.5.2 vanilla with the hydra oc/uv kernal
i had this setup before AND after trying the battery fix and im using the seidio 1750...
frustrations are back from when i first got the phone
I made the mistake of putting 2.2 on my mother's Epic, and she doesn't like the increased battery drain. I'd like to restore her phone back to 2.1, yet she has games on her phone she doesn't want to lose progress on. I've already done a restore to 2.1 from 2.2 on my phone but I did a complete wipe. Would rooting and backing up apps with titanium backup work?
Increased battery drain? I normally get a full day's use out of my battery on DK28. Earlier this week I was above 60 hours of uptime on a single charge.
There is a way to keep apps and settings, but it may cause issues when switching between 2.2 and 2.1. Use clockworkmod to back up the phone. Flash/Odin the 2.1 stuff. Boot back into clockworkmod and Restore->advanced restore->restore /data. You may have problems with force closes after this, but results vary and you may have no troubles at all.
Battery should be MUCH better on 2.2.
On both her phone and mine the drain on battery was pretty noticeable. She's not a big phone technical person but even she noticed it after I updated it for her.
Get mybackuppro and make a backup of just the apps she needs the data on. Then restore that back on 2.1. It will give you the option to backup the apk or the apk and data choose both.

If you go from 2.1 to 2.2 I would highly recommend a wipe...battery life should be better.
Just wanted to further state that battery for me has been much better on 2.2
After a 8 hour day at work (phone off the charger for ~9 hours) I drop anywhere from 25-32% on average... can't really complain with that
I had substantially worse bttery life on 2.2. It seems to be a common complaint amongst many, while not an issue for others.
I'm suspecting that changes in battery life may be dependent on how you use are using the phone. I am pretty heavy user streaming radio, bluetooth, web, games and a 1 hour difference is pretty noticiable. Now if I was getting 60 hours like that other guy, I doubt I would notice an houror even two difference.

While some may debate on how necessary it is, have you "recalibrated" your battery? I put recalibrate is quotes because your not actually doing anything to your battery, but erasing the battery stats on the phone, thus allowing your phone to accurately read the percentage of battery left. If no "calibration" is done, it is possible that your phone may say 10% left, when you actually have closer to 30 or so (just an example).
To "calibrate" your battery, charge it up completely, boot into CWM, go to Advanced->Wipe battery stats, boot up the phone and use it until it turns itself off (dont plug it in during this time). This way the phone can accurately determine how much power the battery has left.

I'm in the group with the poor battery life after DK28, I will definitely give this a shot tomorrow morning after I charge up tonight, however, my issue seems to be with the display under battery use it shows to use most of my battery even with very little use of display, even with long phone calls with the display off it about equals the battery use of the phone call, hoping this will fix it for me
I went 10+ hours with 4-1/2 hours of screen on time. heavy internet, moderate text, 2 20+ minute phone calls. This was with dk28

Before you wipe your battery stats, charge to 100%. Unplug the phone, turn it off, plug back in and charge again until it says full. Then boot into recovery and wipe your battery stats.
For those that use their phone a lot, don't charge while you are playing on your phone. It makes your battery hotter and can decrease capacity. Don't keep trying to turn your phone back on after it is dead, either. That can damage capacity and possibly make the battery unchargeable.
Hi guys,
I'd gladly post this on the CM7 RC's thread over at the dev forum but I have yet to accumulate 10 posts.
Lately I've been experiencing weird battery % issues in CM7RC2 and now CM7RC4, that the charging would be stuck at a certain percentage even if I charged it overnight. It never goes to full, until I pulled the battery and rebooted.
Is something wrong with my battery?
Thanks in advanced!
Are you using an official battery or a third-party battery?
I'm using the official one
I'd try charging the battery to full then wiping battery stats from within Clockwork Recovery.

First, doing the battery drain is effective in calibrating the battery meter but is still probably a bad idea because by doing it you are decreasing how much charge the battery can hold (i.e., a full charge will not last as long). It might not be super noticeable, and doing it once in a blue moon is likely not a big deal, but don't do it often or you'll just end up having to replace your battery. Deleting battery stats should be enough to correct the OP's problem, and allowing your phone to recalibrate under normal use is fine but takes longer.
That said, I do the battery drain anyway, but I would definitely suggest not doing it more than once every 6+ months. Wiping battery stats often is not necessary at all, unless of course you are actually having a problem like the OP is.
Second, you definitely should not clear battery stats AFTER performing a battery drain and recharge. The whole point of doing the battery drain is to let the phone gather new information about the battery since you just wiped the battery stats. If you wipe them again after doing that, the battery drain was useless.
... and from what I'm reading, trigger gives great battery life. So how do I see what has been eating my battery life up? For instance, I unplugged 40 minutes ago and I am down to 91% already.
The regular option on the phone doesn't do a great job of troubleshooting this issue and just says "Display" and "Cell standby" as the relative battery use culprits. I figure, though, that this must be something I downloaded that is killing the battery. I love the ROM overall, but if this battery issue can't be resolved, I need to find something else quick. I'm a slave to a charge port.
Thanks.

Have you tried conditioned your battery by wiping your battery stats.bin? Why didn't you flash the newest Trigger?
Yeah, you need multiple cycles for battery to be even close to accurate, and you should recalibrate.
Are you using other kernels or themes?

Let your phone die wipe battery stats in recovery mode. charge to 100% then use the battery calibration app from the market and re-calibrate the battery. I always repeat the process. Sometimes when flashing new ROMs your batterystats.bin can get a little funky so I always do this after flashing a ROM and my battery works great.
Definitely check the Kernel and Modem your running if there not the ones that came with Trigger than that could be causing your problem as well.
From what i have got from prior experiences. Using odin to go to stock as if your phone just came out of the box and then flashing removes all the old files. When i did this i went from getting almost 10 hours... now my phone gets 17 normal and if i dont use it as much as a normal day it iwll hit 24 hours no problem.

This post (http://forum.xda-developers.com/showthread.php?t=806022) is saying to wipe battery stats at full charge... So what is it?
And why didn't I flash the newest version? It was when I flashed it.
What was the use in the 40 minutes after charge? I could see that if you had screen brightness high, and lots of wifi surfing or video use. I downloaded an app called 'screen filter' and it lets me lower the brightness lower than stock and I have noticed significant battery length increase since use. The stock dim options are not enough. Its still too bright and a waste of battery.

Both. I wipe mine at 0 and at 100 but once you wipe make sure you fully charge without interuption and vice-versa

same here, and i suggest you do the charging during night when your sleeping, so then there'll be no interruptions, like having to reboot for some odd reason etc. That can disturb the process of recalibration/conditioning.

Pretty much nothing... Maybe looked at Facebook once and replied to a text?
So I drained it, wiped the battery stats, then looked at what it was doing - probably 1 minute after it was totally dead and wiped. The screen said it was at 14% already.
In less than a minute - 14%...

Let it die again and wipe again. Your stats are off from the flash its normal. Just let completely die wipe charge wipe repeat. It will take a couple times normally to get back 100% right

I used to chage my battery overnight with good results but since going to gingerbread it usually drops from 90-100% whne unplugging. was reading up and found out it's saftey feature created by Sammy.
