battery Inquiry about SM-G950FD unrooted / Pie ( low screen on time ) - Samsung Galaxy S8 Questions and Answers

Hello ,
i only have this phone from like 2-3 months now i am having hard time getting more than 3 - 3.5 hours of screen on time of battery even after i tried everything i could find on here and on the other websites including : disabling packages - greenify - limiting cpu to 70 pct - lowest resolution - turned off bluetooth NFC edge lighting etc .. only wifi on and screen on max brightness .. everything else is off even a dark theme and a black wallpaper yes i have social apps but most of them in the sleeping apps list so ... is this normal or
i should bring it back to them since its still in warranty ? i am clueless :crying:

Good day.
It does not seem to be normal for me. Try and install Gsam app to see if you have any abnormal app draining your battery.

[Q] Serious Trouble about Battery Life

Yes, it's really official , my battery life is draining like hell... I actually hope that's a battery problem or a rom problem so i could fix it cheaply, but if it is about the phone , i'm messed up .
so here it goes, i've got that htc hero i've bought from a friend so im not entirely sure if the battery is well, at least it was when it came on my hands. I had the official rom, and i cant be sure how many time did it spend without charging because i did change immediately the ROM . Now i have froydvillain 1.7.2 installed and i can say that i putted my phone on charge before i went to bed, when i woke up there was 15% gone from the battery, not so bad, i guess.. the worse became after. i did the usually stuff with it, texting, one or two calls not so much, always not using wi-fi, bluetooth or anything like that at all. not listening to music... when i arrived home there was been 16 h and 20 min and the battery was totally off. when i checked up which program was affecting battery most, and it was the screen and it was taxed as 51% of utilisation, i dont know why , there was just 1 h and 30 min of using it, and i can say the my brightness settings are automatic. Im really getting crazy, i also turned of 3g, only using 2g now to save battery, what a mess here guys. any help ?????

Battery Calibration
Hi there,
I have 1.7.2 also and I get approx 2 days of battery life before it hits 15%. Light usage though. My display usage always seems to be approx 30-50% overall so don't worry about that just yet.
What i think you need to do is calibrate the battery.
http://forum.xda-developers.com/wiki/index.php?title=Battery_Calibration
Do that and once you are on full charge, before you turn on your phone boot into recovery and wipe battery stats.
Should be all good .
Also are you running any overclock? 352-576 is more than okay and should help with battery life... Most people run it on smartass but I get screen wake-up issues with it so run it on-demand.
Give that a go then if that doesn't work come back and ask some of the smarter people for some advice as thats about all i know about battery issues.
i had setcpu installed with some settings, i already uninstalled it, i believe the settings were switched off , thats what i hope..
anyway , my battery is fully charged in 2 hours, is it normal ? it could be cracked, perfectly normal i guess. sometimes when im connected to wi-fi , it starts decreasing the battery level and i watch it lol, 71 , 70 , 69.... thats really strange in due that i see people using 2 days or 3 with normal usage. i believe that's nothing about the rom, im going to do that , im going to calibrate and wipe, text u as soon as possible to tell u the results
9unk, should i use the setcpu with those setting to save battery, im order to obligate te phone to use those settings, or should i just let it default ?
How did this survive in /dev
Also check any background processes.
My hero sometimes just drains like hell untill restart it (as I haven't found out which app yet) .
i believe there are no background apps , but if there is , how could i close it ?
Try calibrating your battery. VillainRom have a guide on it in their guides section.

i just want to note something, here you say you are fully charge in 2 hours, thats strange, mine are 4-5hours charge before its full.
in my experience with all is ON, i got 14 hours of battery life, this what i turn on:
- 3G Data is always on, no time schedule, it on all the time.
- Mail (3 account) and Gmail (1 account), (always on, with 15mnt refresh freq)
- Gtalk and Yahoo messenger (always on, cant live w/o it)
- LauncherPro Friends Widget (Facebook and Twitter, always on, with 15mnt refresh freq)
- Weather with Fancy Widget (always on, with 1hour refresh freq)
- Battery Widget
- Game NFS Shift 3D (15mnt a day, is a must, very love the game)
- Browsing (average 2 hours a day)
- and other normal process and background process (network location, contact sync, etc)
can you describe what is you use in your phone and please detail how much hours you get with your hero??
Mine was also draining like a hell , but i let it switch off for one day and now it works great . try that might it will help you
I had similar problems. Very frustrating indeed, but easily corrected.
Calibrate your battery using the above thread. Usually this takes a while, but sounds like it will be quick for you. Follow it closely and carefully.
Install setcpu and start with a conservative governor at 576/176. That alone should give you a day between charges. Play with these settings until you find something you're comfortable with.

about the screen, i have 5 screens, one has the calendar with my schedule dates, other has youtube and music app, the main one has beautiful widgets that only update 3 in 3 hours, the other has people widget and last one has just power control widget. I believe this is not too much, for instance i already calibrated my battery and look at my stats today :
Activity time : around 17h
apps tha use battery most :
display 41% (45m e 25s);
inactivity of the phone 18% ( 15h e 30 min )
inactived phone 16% (14h e 44 min )
Media Server 11% (14min e 53 s)
the best of this is when im texting there is nothing about the battery when i start to listen to music i can watch my battery drainly constantly, like 59,58,57 per minute sensivily. is there anyway that my battery is cracked or something ? or is just my settings ? i believe i have set all up to save power, i also set up my screen to minimum stats. another thing that i might let clear is that my phone really charges all up from 0 to 100 in 2 hours, really strange that sometime it stucks on 77 for instance other times is draining and draining and it kills me watching other people using 2 days battery with more apps than me
i dont know if this is important or not , my battery drains 6 % on rebooting , dont know if it is normal or not, but im totally sure , aint normal to got all the battery drain in 17 hours with normal using... please i appreciate any kind of help
If you had calibrated your battery, and if you already had uninstalled all the apps that drain your battery quickly, but still no improvements, I suggest you to try the following things:
_ Change rom (I had a lot of problems too with battery life on FroydVillain, I personally recommend Elelinux 6.2 RC, I got an amazing battery life)
_ Make sure you have Update your Radio to the latest version:
http://www.villainrom.co.uk/forum/s...adio-Roms-Download-Links&highlight=hero+radio
_ Try different Kernels, if you are currently overclocking your Phone, I use flykernel 12a, but the 11c is excellent as well for battery life
_ Use sometimes, not set it automatically, some task killer like Advanced task Killer Froyo from the market, to kill sometimes too many running apps.
Make sure to flash the new rom when your battery is full, then recalibrate it again like other suggest you already on this thread.
I personally notice that, when you calibrate your battery, takes a week or more to see improvements on the battery life, so be patient!
Its good as well to restart your new rom fews times to reach the full potential...
Then, when you set up your rom for the first time DISABLE google backup, I've been told that drains battery like hell, don't set the brightness on automatic mode, but just leave it as less as you can, it will helps.
It would be better also to go to setting, under sync, and leave on the automatic sync mode only for the apps that you really need to run..
If none of this will work, if you have can, I would think to buy a new battery, I checked in an official HTC store once and I found it at 30 pounds...
I don't think I have anymore suggestions, I hope it will help you...

To close an app or clear cache or data go to:

and choose the apps you want to close..
I found a major battery killer is an area with no reception.
So if I know I'll be there a while, I'll put my phone on airplane mode to stop it constantly scanning for a signal.
Today i really noticed something strange about battery, i let it charge when it was off. Ive turnee it on, browsed over the internet and it was stuck at 100 % for 30 minutes, than it decreased for 96 in 5 min..

wierd nexus 4 battery

the battery in my nexus 4 started today to drop from 20% to 13% and 7% and then to nothing in no time, like couple of minutes of use,
the wierd part is that its alsot chragin from 0 to 17% in less then 10 minutes!, whats wrong ? im using battery guru and the main drain is "voice calls" with 51 minutes (i really dont think i talk that much !) and then screen with less then 2 hours!
what can i do to check that?
Try charging your phone fully to 100% and see if it still happens.

Battery still wierd ! :
some pics:
after 24 hours of device without charge (only 35 min of screen time, very little use !!! ) only 7 % !!

Download and install the app BetterBatteryStats, its on XDA.
Check your wakelocks, and fix them. There were already alot of threads about this.
okay, what is the diffrence ?

The one is the XDA version, which is free, and the other one is the playstore version, which you have to pay for.
There is no real difference between the two, that i know of. Though, i've only been using the XDA version.
See the paid version a donation for the person who made the wonderful app.

Battery level indicator bug
I faced another weird issue while charging.
Within a minute of plugging my phone to the charger, the battery level indicator changed from 20% to 100%.
I had to restart my phone to reset it back to the actual status.
Anyone else came across this while charging??

and now my screen aint automaticly turn of
plz it important
If your screen isn't turning off then you have a wakelock, and as for your battery, you play games, browse the web, talk on the phone, and have location services running, along with what looks like some background processes. With all that you still get 2 hours SOT, which is actually good.
Cut back on useless apps, and gimmicks, turn off location services, and maybe play less games, then you can push that SOT up to 3 hours.. maybe.
So nothing wrong with my battery ?
what should i turn off?
i prefer not to turn of location services in case of losing the phone or such

send it back to google and get a replacement. same thing happened to my first nexus 4.. i had it replaced under warranty.
Also seems that you dont have good network coverage, since you're getting the msm hsic wakelock.
Try switching to 2G when you dont use your phone to connect to the internet, or when you got a wifi signal.

[Q] Unrooted Note 3 - Battery Drain, Most Tips didn't work.

Hi Guys,
Firstly, I know there are several threads with different tips and suggestions but most of them didn't work for me.
Recently (since more than a week) , I have noticed strange drain in battery and getting hot pretty quickly. It has kitkat and I didn't get time to use it properly in the beginning. After reading different threads and forums here's what I did:
- Let it drain completely, shut off, took out battery for a couple of hrs and then charged without switching on. x2
- Rebooted after charging
- Uninstalled some apps I thought might be problematic
- Factory Reset (such a pain!)
- When attached to Kies, it prompted for Firmware update N9005XXUENC2 followed by another factory reset and hard reset.
- Cleared cache by going into recovery mode.
- Rebooting after charging
But seems like none of it made much difference, my routine use
- couple of hours on wifi
- no heavy games, only temple run, subway surf etc.
- no streaming
- no lengthy calls, not a lot of messaging
- 1, 2 hrs of music
- Syncing off, gps off, blue tooth off, Wifi mostly off, power saving on, brightness on auto, no 3g/4g data, almost no photos and video capturing, sensors, motions off except smart stay
I don't want to root the phone because of my busy schedule, with some difficulty I was able install WLD on it which resets after Rebooting. Point is, I am not a heavy user and this being a "beast" isn't quite unleashing the beasty-battery-life. I do get more than a day but that is when it's in deep sleep for 20hrs or more. I took some screenshots after reseting, updating firmware. It's past 3 battery cycles now, I will attach the latest one's to not clutter it up. I like this phone, but this battery is just not good enough. So, please helpful answers that don't require rooting.
Thank you for reading and Good day!
Is the battery drain consistant or does it happen at certain times (at home, at work, etc.)? If you are in an area where the signal changes frequently that will drain the battery because the radio is using power to maintain a connection. With wifi scanning for google services even when turned off setting make sure it is off if you dont need it. How do you charge the phone? If possible always use the charger that came with the phone, charging from a usb port from a computer is not as strong and can affect the memory of the battery and do not wait till almost dead to charge. It works best to recharge when between 35% and 45%. Look at your background services and see if anything out of the ordinary is running. And it could be possible the battery is defective and you might want to have it tested. I use my Note3 lightly and get 24 to 25 hours over two to three days (turning off at bedtime). This may not help any but this is what I have learned from others with similar situations. Good luck!

Hey MPDnnrd,
Thank you for your response.
It is sort of consistent, did you see the screen is just at 18% and the Android system at 30%? I think this is where the core problem lies - just don't know what and how to fix it.
- Signal Strength: Pretty good, hasn't been a problem
- I normally keep the wifi-scanning off and Now I turned off the location services to see the impact but then I think what's the point of premium device if you have to switch off everything.
- I prefer to use the factory-charger over usb-charging and I read it on several threads to let it completely die and then recharge, guess that didn't help.
- Background services - I don't think so, I kill all the apps as soon as I stop using them, use Greenify to hibernate other, switched off all auto-updates and notifications. Even on Playstore, I switched off the auto-updates and notifications.
- Defective Battery: Now this one, I haven't tested yet not sure how to - the phone's just 2 months old so shouldn't it be good enough?
I know they are not very helpful, but still thank you very much. :good:

I'm sorry to have to say this but I think you got a pretty normal battery drain by looking on your screens. You played almost one hour subway surf(which drains the battery pretty quick) and I guess the other hours where internet (also known to drain battery) or calls/messages. On a not rooted device with stock kernel that seems like normal battery usage to me!!!
However if you like to check these maybe u get a couple of percentages(not that much though I guess):
-Power saving mode in notification drawer makes your cpu clock go down (not sure u got it on not rooted device sry)
-check turn of pen detection in s pen settings
-put the brightness on auto or put it down manually
-if you can change the theme color in apps do so(make it black)
-check the svoice settings so it doesn't listen to your voice
-if you don't care how your phone looks buy a zerolemon battery(I think it makes your phone too big but that's preference)
-don't use a bright background keep it dark colors and no live wallpaper as well
Maybe that helps a little.
I don't see any drain either. Almost 6 hours screen on during 24 hours is excellent, additional 1.5 hour awake time for other services. Excellent battery life.
Settings - General - Applications - disable unnecessary apps
In Google Settings, opt-out interest-based ads and disable location access.
Thank you for your reponses guys - thing is it actually had much better battery life. What I don't understand is the fact that Screen % used to be on top and android os and system was below it but now it has been on top.
I have tweaked quite a few things already that 4aces suggested and the S-voice thing seems new, I'll look at it. Today it didn't even last a full day whereas I know people who even after heavy usage get easily more than a day - mine one, I don't use it this much. The Zerolemon thing is beast but then the phone is a freakin block lol so heavy and big, good travel etc. where you can't charge your phone and has a rugged case.
But there's a change that I saw today, Android System is now below the screen so I am not sure what made it do that but may the next time I charge it gets better and so on. I'll keep you guys posted after charging it today, I'll monitor what I do.
Blondasisko - I wouldn't really call it excellent, but it's sort of getting better than it was in the first 2 cycles. But how do I reduce additional awake time for other services? Moreover, you might've noticed I got till 1% to get this much time like really stretched it to get there.
Someguyfromhell - Already done, locations were off starting today.
Can anyone else comment on their daily routine of usage and the battery drainage ratio?
If I get 12 hours and 4hrs screen time I'm happy. I don't even play any games. Have a lot of accounts syncing lot of Internet and a bit on the calls, gps. I get on average 14 -16 hours
I have brightness on high. If you put it on auto it makes a big difference.

I guess I should feel lucky, I have ZERO syncing, auto brightness, no live wallpapers or gimmicky stuff on, no gps, hardly 10mins or so on phone calls and prolly 30-60mins on messaging a day.
@all others - and the Android System is back on top - what could be the possible reasons for it?
I think its because of such minimal use that the system goes on top. The system still had to operate so when you have hardly used the phone then the system will go on top. Though with that usage you've stated you should get nearer 2 days really

You're right probably, this is what I'd like to know as to what is running in the background that drains more battery? Exactly, at-least 1.5 days is what I should get with this usage. May be I should buy a new battery and see how it works.

The latest update has improved battery life...
Sent from my SM-G900H using XDA Premium 4 mobile app
1 install Android Assistant, search for it on Google play
2 check what apps are using the most Cpu time
3 decide what you need and what you can uninstall (careful).
Mind you, some apps may not appear in the list and be often using cpu time anyway.
In addition, try the app 'Greenify', it can help a lot in saving cpu time and energy, if you learn how to.use it.
Also (only for rooted devices) use Autorun manager or a similar app to select apps you want to prevent from starting at boot.
Hi
I will try tht thanks.
When i look with gsam the android(os kernel) is at 82%!
i think that causes the battery drain right now but dont know how to fix it
Hello
Right now i have this when i got it of the charger. and i didnt do anything with the screen so its less that one minute of screen on time.
I think its pretty bad

I had this same issue. Mine was overheating when i used any app and sucking up battery life like crazy. Yesterday I did a factory reset, reloaded my apps, and installed the latest firmware update (NF6). So far everything seems to be back to normal. No more overheating and no extreme battery use/drain.
oh ok.
I only have the battery drain but no overheating yet
But isnt it to quick to putt it back in factory reset since i only have it for like 3 days

Battery life improved

o recently many users were saying that the four core were maxed out to 2.2Ghz, I faced the same problem, so instead of rooting my phone and putting the CPU governor in On demand/power saving I tried some methods and bought the clock frequency to 1.1Ghz/1113Mhz. I'm still not sure how this happened but here are the things I tried
After a full day use yesterday nearly 3hrs of screen on time and my battery percentage was left to 37% so, I charged my phone to 90% cleared the cache using fastboot, uninstalled useless apps like clash of clans, pubg, Internet speed meter, and some other.
And in Settings>Storage>Free up space..... Go to the bottom of it and delete a app with green icon.
Note clear only cache
And the results see the images. I can't guarantee that it will work for you, but it worked for me.
As you can see I don't have root accces, so this is done without rooting.
Wrong thread..
Some other tricks
Yesterday, in just 1h 30m hour, my battery get drained from 100% to 75% without screen time and app usage.
So, I just remebered that, on iPhone I hadn't Facebook app because it consums too much of the battery, then I uninstalled it from my A2 and "bingo!" Battery today is far better than before.
Other trick is to disable WIFI when no in use.

And I have the same problem. I disable all apps from backround, make factory reset, but the problem not solved. Maybe a firmware update will solve the problem.
Nitpicking but...
Your first four CPU cores are still stuck at 1401Mhz,should be 633Mhz. Room for improvement.?
