I switched over to a rooted phone about 3 months ago and had slight battery issues for the first week or so. I'm guessing I had about 7 hour battery life at the time and i just got used to it. I flashed CM10 onto it 3 weeks ago and everything has been fine except for the battery. it's completely sporadic. Sometimes it seems like a new phone. With battery lasting the whole day. But other times I can't even squeeze an hour out of it. I just woke up today, booted up Airdroid on a full charge, installed one app and the next time i looked down I had 20% battery. I check the battery page and it always says that the screen is taking up all of the charge even though I keep it less than 25% brightness all he time. Help?

So it's day 2 with my new SGS2.
Picked it up from the store fully charged.
Since it dying once or twice due to battery drain...I noticed it takes a crazy long time to recharge.
My past phones only took maybe 3hrs Max to get a full charge...this one is much much longer. Any ideas?
I'm rooted....stock rom.

I bought my Gnex from Handtec at the end of November. I have been very happy with it Until 2 weeks ago. Battery life has not been great but has lasted 16+ hours each day and I always charge overnight so this has not been a problem to me.
I take phone off charge at 7am. A couple of weeks ago I started to notice that instead of 50% at 7pm it was showing only 20 to 30% charge.
I bought BetterBatteryStats which showed no WaveLocks.
I started to freeze apps using Titanium Backup.
The battery life did not improve. I noticed the phone was getting noticeably hot to the side of the camera and charges were taking much longer. Instead of 3 hours it was taking longer than 7 hours.
Last weekend I noticed a drop of 70% in 3 hours on 2 occasions.
So I decided to wipe the phone and install AOKP build 15 with Franco kernel 10. I did not re-install aps. I charged he phone after install which took all night and then reset the battery stats.
The phone has continued to be hot and discharge very quickly. Charging is very slow. If the phone is off - charging appears to be even slower or not take place at all.
My Gnex is now fully discharging in less than 5 hours when idle in flight mode and is always very warm without any use.
I have been using a Samsung galaxy s2 wall charger.
Is this likely to be a faulty battery or phone hardware fault.
Any suggestions for next steps or is it a Samsung repair job.
Thanks

well, whichever it is, it sounds like a hardware problem that should be warrantied. i would flash it to stock and get it repaired by samsung, or see if the place you bought it will take it back
I get a similar problem but i return it back to vodafone 2 days ago and now waiting for the results, i returned it a week ago and they only give me a new battery to see if that will solved the problem but nope it persist, now they too it for either repair or replace ....

I am on the same build and recently used francos kernel. At night the phone would drop 20-30% of battery on airplane mode. Installed the apex build 5 kernel and all the battery nonsense stopped straight away. It seems to be a great kernel especially with AOKP B15.
Hope that helps.
My S3 is normally have really great battery life with disabling unnecessary features and turning off unnecessary functionality. With normal use and with wifi one it has battery life more than a 36 hrs. But at work because of poor signals I hardly gets 20 hrs. and I can understand that problem with poor signals.
But, Ones and while battery dies in 3- 4 hrs. I fully charged my cellphone at night and took the charger off mid night Battery at 40% in 4 hours. without use , where no application or wifi, data plan running. and many time it just die if I don't get up in midnight. This happen so randomly no proper time duration. some time no issue for month or week. Some times I seen this behavior in day time, phone got really hot... I just restart phone and it will fix the issue.
I didn't root my phone running on Jelly beans. Should I contact Samsung or bestbuy from where I purchase.

This is a daily problem for me ever since I bought my device so I got used to it. Rooting the device with a stripped down ROM fixed my battery life issue. But I reverted to stock in anticipation of the 4.1.2 update for the i747.
Hello, a couple of months ago my battery started dying on me so I went to Samsung to get a replacement (my tablet is still within warranty). Despite the fact that my Knox counter is triggered they've changed my battery as well as my tablet's motherboard (don't know why). In the first few weeks I would get quite good battery 7-8 hours of Screen on Time, so far so good.
In the last month or so -though- I'm starting getting quite worse results. The battery leak while sleeping is 2% every 8 hours, so I'm great there too (amplify + greenify work miracles), so the only thing that I can think is that the battery has started dying again (already?). I've let my tablet reach 0% and shut down on its own. Then I booted into recovery and let my tablet on with full brightness for another hour until it was finally off. That's *one hour on* with full brightness!
It seems obvious to me that that's a calibration issue. I deep cycled my battery (twice!), but the results persist (battery is 0% after 5.30 hours of SoT, an additional hour of full brightness is needed until my battery is really depleted). I've made the calculations and found out that if I could actually use that extra hour of full brightness, I would still get 7-8 hours of SoT.
What happened? Why is my battery suddenly got itself "decalibrated" and why does deep cycling (or deleting the battery starts) never works? I think that I should get my tablet back to Samsung again (it's still within warranty), but I would prefer not to as it'll take another 2-3 weeks (again!) to fix it and I'd much prefer to have my tablet in the meantime. So do you have any quick and dirty method to get my 2 hours back?
BTW I know that 2 hours less of screen time , sounds little. But it's exactly the amount of time that deems whether I should charge my battery twice or once every day (yeah I use my tablet *that* much, as it also doubles as my laptop on the go)
Hello,
I need help about battery replacement,
Let's tell a short story:
I bought my Zenfone 2 from a technology supermarket (it's a national one, so it's reliable), a second-hand Z008. When I first bought it, it was running stock LP and I rooted it 2 days after. At that time my battery was still very good (>4 hrs SoT). 1 month later, I go on vacation, use it all day and get about 3hrs SoT. I accidentally bricked it then. I received it 1/2 months later from Asus service centre, battery life seems got worse (4hrs SoT). 1 months later, I went on vacation again, the battery problem started here. I used it all day and get 2hrs of SoT, but it drains very fast at 20%, and overheated (.69 beta MM), it went 20%-0% in a few mins. I wiped /data and the battery seems little better. 1 months later (recently), it started to get VERY BAD. after a full charge, 9mins SoT = 5% with Facebook on wifi. Only 2h30 of SoT with Facebook and Messenger. I've used all rom to check whether it was a software bug or my battery is facing a big problem. Stock LP, stock MM, CM12, CM13, AOSP has the same battery consumption : 2h30 of SoT. Now it charge very slow, it can't even reach 100% (very few times it can reach that).
Should I replace my battery??
Thanks in advance.
Edit: I sent it to service centre
Lol That must be my Z008?? which I exchanged with RN3
If you're rooted, check to see if anything is keeping your device awake for a long time with Wakelock Detector: https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en
I had horrible battery drain one day, and I looked in WLD and realized that Localcast was keeping my device 'awake' (screen off still) the entire time.
