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?

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'd venture a guess that you have something else running the background. I honestly wish that I had something more for you, but I'm going to have to fold.

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.

I was about to do this but now I am skeered.
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
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.

I would definitely try this.. I had the same problem and it worked for me.. after you reset the stats, drain the battery again till the phone dies, fully charge again, and wipe again

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.
Hey Guys, i have noticed before i did my restore through CWM Recovery that my battery life was at 30% and after the restore it jumped up to 73%!!!! After that i was skeptical about what the restore has done and i am seeing a discrepancy in my battery life before and after =/
Any reason for this?
I also tried wiping my battery stats and doing a battery calibration through Nemu's app (Battery Calibration) and still the battery is nothing to what it was before. Before it would go a whole day before i needed to charge it and when i did charge it at the end of the day it would be at 20% or so with heavy use and a lot of phone call time, but now the battery life only sustains for about half a day if that with very minimal use and light talking, in fact it drains at about 10% every 2-3 hours when i have the screen off...
Any hints on as to why and how to prevent this again should i do a restore through CWM Recovery?
I noticed a similar effect with my Atrix 4G, however I forgot about it until I saw this topic.
Not sure why it does this but I have noticed similar results multiple times. After any wipe or restore I try to do a full charge with the phone off. This seems to help, or at least gives me peace of mind...

well going from 33% to 70% could be normal since recovery replace the charge .bin so you are actaully charging you device. try pull the battery an recharge,
maybe there is a rogue app try start "freezing" som apps one by one and check battery
didn't realize it was that extreme, but ^ is right, you're charging while you mess around in CWM. i went from ~15% to 40% on the next boot while reinstalling GB 3.5
Hello,
I have extended battery in my Atrix and I see it going from 100% to 50% in like 4 hours. Then I shutdown Atrix, boot it up and battery shows 88%. What can be causing it? Is it battery or OS?
G
Probably just compatibility issues. I do suggest running a battery calibration app or clearing battery stats in CWM.

Yes, you are right, just installed GB couple of days ago. So I don't need to do anything specific to make it work eventually right? I cleared Battery Stat in CWM.
Is anyone experiencing weird issues with battery before recharging? i had 2 days phone on batt and 3hrs screen on. It was at 53 % before i decided to charge. I fully charged it and now im losing 10% every hour even with phone on idle. Its weird cause every other charge will last a long time.

Yeah, I'm still stock on this phone and I'm getting inconsistent battery life. I usually charge every night, so I'm running about 16-17 hours per day. Almost identical usage each day but one day I'll plug in with 45-50% remaining and the next it will be dead when i plug in. Very odd. I'm going to root this thing just so I can get rid of the bloat apps. Well, that may not be the only reason I root. I may be compelled to put some AOSP on this and see how it rocks it.
well i don`t really recommend to ROOT stock rom, it caused for me a battery drain ! also KitKat known for drain issue even on Pure android on Nexus 5. I don`t really know a fix but i`d give u some tip and it might help
1. Re-flash D80020c
2. After re-flash do a factory reset
3. Don`t root or mod your OS
4. Turn off Sync or Location Service (or set to battery saver mode)
i did those steps and i have 34 hour on battery:
3 Hour screen on time (and about 30-40 min gaming in this 3 hour)
Left about 49%
i hope i helped a little
Potential solutions:
Have a look in Settings > General > Battery and see what seems to be using the most power. You could have a problem app that’s using GPS or trying to update frequently. If you can identify the culprit then you can remove it.
There’s a slim chance you have a faulty handset. If adjusting your usage and tweaking settings doesn’t’ result in any improvement then take your LG G2 back to the retailer or carrier and get a replacement.

I always have location turned off with all bloatware rwmoved. I honestly think you have to drain it to about 20% then charge. Cause i never have problems when i do that. Gonna try and drain it out again and recharge and see what happens then.

Its kitkat,it says rooted d80020c in my signature. Well here is my latest results. Left it on overnight and was at 53% with data off. Checked it this morning and everything was back to normal again no battery drain or low estimated battery times.weird cause i charged it around this percentage. I think you have to take it down to at least 20 before charging will find out later today when i charge.

well i really not heard about Deep sleep drain but while idle it`s drains bit faster then JB, with jb i could get max 40 hour and about 6hr screen on time and + 10-15% battery while on KK i can get 42 hour but about 5 hr and 45 min screen on time with 0% battery it`s seems a bit problem for 4.4.2 i think Google will fix it and hopefull we`ll get new update from AT&T if this prob will fixed
P.S i saw that if battery at 100%, overnight it won`t fall to 99 but while battery is on below 100% it drains about 1-2 % overnight is that a known prob?

2% overnight is pretty good, given that it's on WIFI I'm assuming?
I lost 25% overnight last night when I was off WIFI, so I factory resetted mine.
Took it down to 20% and discharged and its fine. Im guessing its a bug,but, easy fix just take the battery down to 20% or lower before charging
