Galaxy s II - i9100 Cm 12.1 Battery Fast Discharge - Galaxy S II Q&A, Help & Troubleshooting

yea so I got cm 12.1 installed on my phone. perfectly working. but I just noticed the battery discharges so fast. I got 100% charged battery but after 30 mins of usage, only 73% of battery is remaining. But I checked my battery status/usage on settings, but all of the apps are using only about 7% below of my battery. Last thing I noticed is that when I open up my wifi, every minute, battery drops. If I play games (wifi off) the battery isnt dropping that hard. But If I play with wifi on, it discharges dramatically. Is this thing connected with wifi things? how can I solve this ****ass thing.? please help:laugh::laugh::laugh::laugh::laugh::laugh:

Go to:
Settings -> About Phone -> Battery Use and check what is draining your battery.
You may also use consider lower Min CPU frequency. I'm running on 19 MHz.
i did nothing it that hour with my phone all i did with my phone an placed it on a table and watched tv
You might did nothing but some widget could drain battery like hell Check battery usage as per my first post. I'm using Elelinux-7.0.0-RC0-Hero-v0.7 and my battery life is very good, with all stuff "on" except BT.
but after i while the battery life a bit better
Have you tried to reboot? I just realized that after first reboot after I flashed new rom Android Service process was draining my battery like hell (3 times more than Display), my phone was down within 3h. But after I rebooted everything was ok.

[Q] Battery Issues

Ive been having a weird battery issue. my battery gauge will say its at 15% or whatever it says at the time. ill plug it in and like 10 minutes later it will say 100% battery is fully charged. Obviously its not 100%, even when I charge it overnight, when I unplug it itll be stuck at 100% for like 2 hours then all the sudden drop to like 85%. im lucky if my battery lasts 12 hours now , same thing has happened on different roms. Do I need a new battery?

I'd try a different ROM/Kernel, see if that makes any difference (after clearing batterystats in CWM).
If that wouldn't help, I'd say battery is ze dead.

tried differents and kernels, and wiped battery stats guess my battery is done
try "battery calibration" app. it helps me a lot, and keep my phone running longer. i can last almost a day with medium use.
i have also tested with on screen non-stop (wifi + online game that require wifi, brightness roughly around 30%, medium volume, with whatsapp and talkbox in between), in conclusion, i can run for 4hours plus straight with sufficient battery left. i never push it through, i think i can go for 5 hours if i want to.
battery calibration app can be found in play google store
Worst battery life evah!
Im having issue with my battery as well, I plug it in a electric outlet for about an hour last night and when i saw the charge, it was only like 49%!!!!
And today, before my meeting it was like 22%, after an hour of meeting, BOOM! EMPTY BATT! What I only did was surf and checked my calendar!
It charge slow! And its draining fast!
something happened to my battery before last month, when i charge my fone it says 88% then suddenly after few mins 1 or 2 it become fully charge,but when i unplug my charger it comes back to 88% again, i tried some apps like battery calibration and also i'm wiping the battery stats in cwm everytime i flashed a new rom and it helps my battery charge in normal and accurate level...i'm using also cpu spy to checked if my fone is going to a deep sleep. now my battery lasts for 1day 11hrs with light usage. but for heavy usage i've got 40% after 4hrs of continious hd gaming.

Poor Battery Life on Captivate Running 4.0.4

I have a Captivate running Dark Knight's 4.0.4 and the battery life I get is very poor. Usually it says that Android OS or Google Services is taking about 30, 40+ percent in battery life. I get about only 10 hours of use with the device, and i still get battery drain even when it is in sleep. I've checked better battery stats and gtalk_async_conn has been waking up the device. I disabled all syncing, and in the Play Store disabled automatic checking for updates. I've tried calibrating my battery also but nothing, mainly since the phone cant turn on for some reason while it is charging. But no matter what I do, that process is still killing my battery. Does anyone know how to fix this? I had the phone off and charging for 12 hours, and 1 hour has past since i turned it on, using the phone for about 3 minutes, and the rest of the time it was in sleep, and the battery is down to 91%. Please Help!

[Q] Android 4.4.2 draining battery too fast?

I recently bought the Google Nexus 5 which had android 4.4.2 out of the box. The phone is awesome but there's only one problem: its battery drains out too fast. My phone has been lying idle since 7am in the morning and its 11 am right now and its already down to 65% (mobile data is on though). Iv to charge my phone atleast twice a day. My friend has the same phone but he hasnt updated to android 4.4.2 and his phone runs almost a day with medium usage.
According to the battery stats, Android app is draining most of my battery (47%) which is even more than the screen. Is this normal? And is there anything i can do to fix this problem?
My WiFi is swiched off. My screen brightness is set to 30% and iv disabled google plus as i read in some forum it causes the battery drain, Iv also disabled google now and location settings are also switched off.

[Q] EXTREME battery drain while idle

I recently installed CM11 on my S3 with tmobile and the battery drainage is terrible. Ive searched other threads and the rate that others drain is miniscule compared to mine
I charged last night and went to sleep with my phone at 100%, when I woke up it was off, when turned on, 2%
Below attached is the screenshot of battery usage
I had Juice defender on, i set everything off (i think)
wifi was off, location/gps was off
I even turned off the blinking indicator light
20% an hour while idle means i'm obviously missing something here, please help? I don't know what the bars in the image mean but i was pretty sure i turned both those off
What can I do to fix this?
Go to Wi-Fi - advanced-untick always scanning
As for GPS some app might be using it...
For battery Install better battery stats and give it root permission and let it stand for 4-5 hours... And see what's causing your battery to drain...
