[Q] Battery drain

My battery drain from 100 % to 96 % with 4 minutes of active screen??

My battery drain from 100 percent to 1 percent after 1 day usage with 6 hours on screen time. Please help. Oh wait batteries normally go down when in use.

Yeah, i'm still a bit neurotic with this :silly:

it depends, what are you doing with active screen? when i play coc my battery goes down fast.

Doesn't matter what he is doing. He cannot calculate the right consume of the battery just by see how long it go down 4%. The system did not set up properly yet and maybe he using at the same time, WiFi, Bluetooth and so on.
This thread is useless as there thousand out there.

You will need to see a complete cycle before you can assume that you have battery drain, like how much it goes down if left overnight, I personally only lose 1 - 2% overnight which is about right. But the second you fire up a game it will munch you battery, same as can be said for Wifi when downloading or setting up your phone, so if this is the first time you've used the handset, it's more than likely a little premature to say what your battery life is going to be like, give it a week and then see where your average 100% battery charge gets you, by all accounts a day and a half to two days is quite normal according to some users on XDA, but then that would depend on the user.
One thing I did find with the Z1 was that when gaming the average battery use is little higher than I was used to with previous phones.

You could try underclock your processor (I have clocked my processor at 1.5 Ghz) it will save you some battery. In addition you could try undervoltage but you must be extremely careful with voltages as very low could unstable your phone and very high can fry your phone (if you are newbie do not try it ).
These are some ideas it is your choice if you follow any of them not mine.

Excess battery drainage

I have spice drean uno ruinng 5.1.1 official rom.
After using it for a while i am seeing that battery is being consumed very fast.
I tested it with temple run oz for 30 mins and battery moved from 100 to 48 in 30 mins.
Is it normal or something is wrong with my device.

Battery health depends on individual usage and maintenance. There have not been any such battery drain reports. Maybe get a new battery, that will help for sure.

I bought this 4 days ago.

Try this
Calibrate your battery with battery calibration app.

Then maybe you got a manufacturing defected piece. I would say bad luck. Try to get stats of battery usage in settings. Android 5.1.1 actually improves battery, Google claims and as I've noticed so it's hard for me to believe that it's causing the problem.

I fully charged to 100
Turned off my device so that system uptime would reset
Then turned my device and wifi downloaded skisafari and gave it to my small cousin for 1 hour 56 mins and battery went to 74%
Battery discharged from 100 to 74 in 1 hour 56 mins.
Is it okay ?

Yup, its normal, switch back to kitkat if u want a bit better backup.
P.S: Most android phones gives only 5-6 hours backup on moderate to heavy usage.

Backup depends on usage, you are sending a screenshot of deep sleep.

I don't think that this is a truth

Battery drain

So I am currently on 5.1.1 rooted with Franco kernel. Before updating to 5.1.1 I had 3h and 44 mins SOT and still 16% battery left. I read that flashing Franco kernel will help my battery but I am currently on 55% battery with 1h and 40 min of SOT. I have greenifyed all the battery draining apps like Facebook etc and I don't have any widgets expect Google keep. I have attached couple of pictures if someone could please look through them? I did several factory resets and still the same battery life. I am just browsing and watching YouTube videos. Now I only get 3hrs and 15 minutes before my phones dies
It's driving me nuts, I read that Franco kernel will help my battery life but it's still the same. I have around 40-50% screen brightness.

Have you done any modifications to your CPU or anything like that?
Profiles/governors etc.

No nothing. Just flashed Franco kernel free app so I can't adjust any governor

regardless what you were told, flashing kernels does not help battery. its your use and the quality of your signal that will determine your battery life. kernels might help you in saving battery, because they all change how the CPU works, but its up to you to save battery, not the kernel.

Yeah I read that you'll get better battery life with Franco but I don't know. Is there something unusual from my screenshots? Is there anything I can do? I mean I am using my phone as normal as possible and I even turned of lte and running only on 3g. I just want to know what the culprit is. I even removed viber but it's still the same issue

what percent brightness do you use? I keep mine at about 0-10% mostly, and average around 5.5h sot. if I raise my brightness to about 30-35%, I lose about an hour of sot. but really, its all about what you are doing with your phone. if you are a heavy gamer, you'll see much less sot because CPU intensive games will go through the battery quickly.

Your best shot is getting the full version of FK app and then controlling your CPU.

40-50% brightness all the day. Not playing any games just browsing and YouTube. 10% is really low, you can barley see

actually, 0-10% isn't that dark. if you set adaptive brighrnes, 0-10% will actually be darker. 0-10% is fine for me, unless out in the sun. but with 50% brightness, I'd say 3.5h sot is actually fine.

Really? I have 50% on all of my phones. I'll try 10% and see. Is activating the adaptive brightness good for battery life?
Just want to know really if my apps and system is behaving correctly. If it's the brightness that is the issue then it's a relief. But I read that everyone got better battery life with 5.1.1 except me :-/ I mean I have Bluetooth off, gps off, hepatic feedback and sounds etc all are off. Even Google now is off

no, adaptive brightness is bad for battery life.
and for the majority, battery life is exactly the same on 5.1.1, like before. as many people that claim better battery life, just as many, if not more, will say its the same, or worse.

Of course that it would help. I got 7h SOT with my old S3 running a custom kernel. But after all.. Try it out yourself

Yeah that might be hit or miss with every update. But I still feel like one should get better SOT even with like 40-50% screen brightness, I have all the big battery hogs turned off like GPS etc

I am running the kernel but it's not optimized and I don't know what the default settings for Franco kernel is. I thought I try the free version to see if I get better battery life but I feel like it's almost the same as stock kernel

first off, paying for the full app will give you what, more control of your CPU? do you know how to control tour CPU? if so, there are many FREE CPU control apps. learn what you are doing first, then buy the app. secondly, no one that uses 50% brightness gets great battery life. the screen uses the most battery, raising brightness to 50% will just let it use MORE battery.

I know that you can control your CPU, I've don't it before on my older android phones. I'll try the suggestions regarding the brightness

Ok so I downloaded Franco kernel the full version I will try it, what settings should I try for best battery life?

that, my friend, you have to find. considering that we all use our devices differently, you have to find what works for your device best. there isn't a magical setting for battery.

Screen On Time

Guys, How is the screen on time on P9. I'm getting about 6hrs 15 minutes on SoT on average. What about you guys?

Are you kidding? What is your firmware version and what is your usage pattern? Mixed, gaming, browsing ... Thanks.

I'm on EVA-L19C636B393. I generally get about 14-15 hours of use. I keep my brightness at about 25-30% and have it auto when outside. Almost always on WiFi. watch YouTube alot and do a lot of browsing. Play 30-1 hour of gaming per day. Use Reddit alot. I also have installed NAPTIME app even though I'm unrooted.

Im getting better SOT than my nexus 6p

Can someone please do a battery test on Antutu Tester (availible here: https://play.google.com/store/apps/details?id=com.antutu.tester ). It can be a short one, and tell me the score. Please, thanks in advance!

Abnormal battery drain onscreen per hour?

So I just installed AccuBattery Pro and my battery drain while on screen is 12% per hour. Is this normal or is it too high? This is for WiFi-only usage scenario, I use Netflix/YouTube, read some PDFs, chat via Messenger, surf the Internet (Samsung browser), sometimes I visit reddit/instagram/snapchat. Majority of my apps is put to sleep when not used. I have the Exynos variant.

10% - 12% battery drained per hour seems so normal in my opinion. Mine also faced the same as yours and I always got pass 9h of SOT.
