I have a Samsung Galaxy S3 i9300 with ROM Blekota Note 4 Lite and Boeffla Kernel. It was great for about few days, but now I have high battery drain by screen process. I have minimal brightness, i don't use phone most time. After 8 hours of school I have 64% battery (when I was sleeping, phone was charging, when I wake up it was a 100% battery), I've been using it only for a while few times, for example to write few smses or search something on Facebook. Why Screen uses so much buttery? How can I fix it?

Screen processes in not only a brightness fact, it combines gestures, touch screen games (well, all android games ) ecc...
For example facebook too is a screen process.
Download Greenify from playstore and hibernate all the app BUT the notification apps you need (for example if you hibernate clash of clans, you won't get notifications from it).
Also, with greenify you can choose between 2 hibernating methods.
1st: tap to hibernate
2nd: auto hibernate apps (root).
And also there's even a more efficient one but it requires Xposed framework.
Try hibernating your apps, and tell us if you see changes in battery life

Post a screenshot of your touchpad's battery usage chart, what rom you are using, and any tweaks you have used to achieve the life.
Here's mine...
ROM: Cyanogenmod 9 Alpha 2
TWEAKS: using setcpu to make my TouchPad go into deep sleep (192mhz max and min.) while the screen is off.
LIFE: Can squeeze 12 hours with hours of gaming and browsing.

Does your touchscreen ever become unresponsive after waking it up with that low of a setcpu setting?
No. I have never lost any responsiveness. The only time I had a problem was when I locked it and itsleeped while temple run was running. Then the game became choppy and I had to restart the round

I've just started using Juice Defender (purchase version) to switch my WiFi off when the screen goes blank. I've put some exceptions in too, so Titanium Backup and others can wake the data connection up for syncing if required. Improved standby power saving considerably.
JD also shuts off Wifi after a little while of no data throughout. This can be handy if you are doing something that does not require data, such as games.
Orange, just a suggestion, use powersave scaling when sleep is on. This will peg the clockspeed to the minimum. The only difference between that and what you are currently doing is that it will no longer need to scan to see if it needs to increase or decrease the clockspeed.Theoretically it should save battery.
People usually talk about battery life for continuous usage, but i want to ask about battery life when leaving the phone off ?
After a few tweaks, i noted that betterbatterystats shows my phones has been booted on for 5 days 15 minutes, out of which it's been 4 days 5 hours 20 minutes in deep sleep; and only seen 1 hour 59 minutes of actual usage (screen on basically means when i'm actually actively using it)
unplug means when i unplug it from usb charging after it was already 100% fully charged.

So how does my phone battery stats compare to the normal life time for the Samsung S3 when not in use ? just wondering.
I give most credit to greenify for helping keep my phone in deep sleep mode most of the time. Apps that are waking my phone is mostly googlemaps, and greenpower (left this ungreenified because it managed when to turn on/off my wifi, when i open screen .... which it probably can't do if i greenify it)
other than the few wake locks; the wifi on is mostly due to syncs. I usually set my apps to at most only sync when i turn on the app, or at max once a day. Greenpower will trigger to turn on wifi when the app requests access :X
PS: i'm using wanamlite and adam kernel. As well as philz CWM touch for root.
Hello, 3 days ago I've installed CM10.1 nightly build from 2013-07-25 on my friend's Galaxy S III (international), now his battery life is really bad and he's complaining on me, any way I can improve the battery life?
Here goes a screenshot (as you can see, he wasn't even using the phone when the battery just dropped 50%):

Cyanogen mod roms are known to drain battery much faster than touchwiz.so you cant really expect the battery life to be the same as on stock or stock based roms. you may improve the battery life by using an app called Greenify. it hibernates apps so that they will not run in the backround. this can help considerably. also make sure to turn off gps , bluetooth, wifi. and mobile data when not in use.
well first tell your "friend" that thats how things are in AOSPs. Secondly use differrent kernels and proper setting to get max battery (tutorials are available) plus greenify apps you do not use. And the usual killers as GPS/WiFi/NFC/3G use only when needed or turn them off..
Something is extremely wrong there. Get a normal usage BBS dump and post it here. Also take screenshots of the BBS pages.
Also post a screenshot of your battery stats page (one that shows which apps drain battery).
I've been using greenify for a long time.
i dont really know whether it is helping me save battery or causing me more trouble.
since opening a hibernated app has a tiny delay. not noticeable in most app, but very obvious for facebook.
opening a hibernated FB and you have to wait it load from scratch and stuck at the splash screen for 1-2 seconds.
below is battery info of 2 days. both approximate in standby for 7 hours. in the same spot on my table connected to the same wifi.
First one, with greenify.
almost all user apps&games and many unused system apps were greenify. only messaging apps like viber whatsapp hangouts, and google search were left untouched.
second one, with greenify uninstalled.
i left google+, chrome, and FB running in the background (open the app and press home button)
wakelock duration is almost twice compared with with greenify, FB being the biggest culprit
but strangely...the battery drain is the same, both left with 97% after 7 hours.
greenify doesn't do much to help save battery.
and in the case of FB, it causes unnecessary delay for app opening.
do you still think it's worth using greenify?
with greenify

without greenify
The advice is to greenify apps selectively. Excessive greenifying will not help and may result in the opposite. Especially, greenifying those apps that you use heavily. May be that is your issue.
Sorry to derail, but what ROM/Apps are you running?
That battery life seems pretty good!
Hi all,
I have a Note 4 910F on 6.01 (unrooted) with dreadful battery drain to the point where under use I'm hardly lasting a day or less which is ridiculous under medium/light use.
As seen in the images below the phone (since I got it) has been awake all the time (even when screen is off) except when its turned off. (I disabled WiFi on when sleep mode)
It will be awake in airplane mode and in safe mode so its not a 3rd party app problem. All bluetooth/nfc etc disabled. I have tried phone cache clear, app cache clear, reset.
I've used wakelock detector to grant battery stats via pc and see screenshots below for the wakelocks. I've then turned on the phone and have not touched anything for over an hour to show awake stats when the screen is off.
I've been all over the net searching for an answer but I'm pretty new to android stats etc. This is one of three batteries I have btw, all of which perform the same, so to me it must be software related. I am prepared to root the device to remove software that could be causing issue if it will solve it...
I have disabled Google+, Google Now, No Voice commands present at all or gestures.
Can anyone tell me the issue and how to solve this battery drain???
