How to fix Battery Drain on S7 Edge - Samsung Galaxy S7 Edge Guides, News, & Discussion

REQUIRES ROOT
So some of the users of the S7 and S7 Edge are saying they are getting below 4 or 5 hours of SOT with normal use. Today, I have a solution that worked for me and I hope it will work for you. I only own a Exynos S7 and so I'm not sure if it will work for other devices. But do try it out if you are getting bad battery life.
Remember try this ONLY if you are getting bad battery life. If you are getting good (5 or 6+ SOT S7) battery life then you are okay.
First of all, I would assume you are using some kind of battery life saving app (because who doesn't want better battery life) like Naptime, Power nap, Amplify, Greenify, etc. Now just uninstall of all the Power saving apps. This may sound bad, but trust me.
Next, install a custom kernel. I would recommend Modified Stock kernel as it's not over clocked and Prometheus kernel as you can under volt the CPU. Do not over clock the CPU if you do not need to.
Lastly use the smart manager in the S7. Settings-> Battery->App Power Saving and select the apps to save battery.
Let the phone go through a few cycles before reporting back
Let me know if I helped you and a 'Thanks' would be appreciated.

I'm on S7

i´ll try some configs without change the kernel, because i want to use Samsung Pay, so I can´t play with knox haha
i just change on configs and put all my apps to save energy always, everyone was on automatic...
i´ll try to use with power save mode too, but i´m almost turning it off...it´s to noticeable the slowness...
let´s see if i can improve my batery life, i never can do even 4h off screen on -.-

Do not put all apps to save energy, you will have problems with notifications. Just the apps that you don't really use and some games not the important ones.
Also try this: http://forum.xda-developers.com/galaxy-s7/how-to/standby-drain-2-8-hours-wifi-bit-4g-t3416864
It does not require root.

(TIP) Saving Battery Life on Galaxy Note 3

Didn't see it posted so I though I be the first, If it was sorry.
How to Increase Battery Life on the Samsung Galaxy Note 3 or Simply how to make it last longer though out the day. Have another Tip? Leave a comment and let me know, Ill add them.
My Top 10 Tips for saving Battery Life.
1- Enable power saver
2- Disable unnecessary features & gestures
3- Turn off WiFi & Bluetooth when not needed
4- Delete unused widgets
5- Close applications that you are not using
6- Toggle From 4G to 2G
7- Disabling Background Data:
8- Changing Application Sync Settings:
9- Set Brightness to ” Auto ” and lower Timeout Duration:
10- Avoid Live wallpapers, instead set Dark wallpapers.
Thanks for the tips. But if I follow that, what's the point to use such an advanced smartphone?

Samsung crams SO many features into their phone I doubt you or really anyone uses all of them regularly (it's not like you can't turn anything you want back on). Also some of these are just temporary when you really need to conserve power; like Power Saver, which really degrades the performance of the processor and GCU or switching to 2g data.
Tip No. 11 Turn your Phone Off...
Thanks a lot.. But if turn off the device saves a lot of battery jeje.

- Turn off mobile data when you're not using it. This can save you about 3 days of battery live. In one go.
- Turn off Auto Sync. Did you seriously think something that connects to the internet all the time did not drain your battery?
- Don't use Auto modes. Yes, this includes brightness. IT'S A SENSOR, GENIUS. Sensors require power. Just turn down the brightness yourself. (30% is more than sufficient in ordinarily lit rooms.)

Well have you every been stuck without a way of charging? There's times I know I wont be able to charge my phone and it might die so i do these things in order to improve and prolong my battery life.
Take a brick charger with you :laugh::laugh:
Unless you mean to do this when you're running low once in a blue moon, then ok.
Otherwise what's the point of the phone?
I do the literal opposite of your list.
Full brightness (unless I'm in a dark room)
4g
Syncing 4 gmail accounts
Syncing Microsoft exchange calendar
Power saving mode off
Facebook connected
I do have a fully charged original note 3 spare battery on me at all times though.
But I rarely need to use it before 7 pm (12 hours after taking it off the charger in the morning).

Yes, I do have. My solution is tha I will carry 3 oem batteries...plus a 10000 mah battery power bank.
I only got the spare battery yesterday.
I was still running on full mode before the spare battery. I made sure my phone was always charging (while at office, car or home).

Indeed... I do 7 hours a day by train, in which I have a 70% chance that I might have to spend half of that checking the travel advisor for an alternative route. I know what it is like all too well....
To me battery life is more valuable than knowing my neighbour managed to write a Q on her visit to the bathroom.
Is there any way to turn off data when the screen is turned off in the settings? Similar to the htc ones power saving option

I think juice defender does that.
The thing I like about the Note 3 is that battery life is not an issue anymore, provided that I can charge it overnight.
Today, I've been on battery for 17 hrs straight, including phone calls, 90 minutes of navigation, Internet use etc. And there's still 28% battery left.
My point is: if the battery life is much less, there's something wrong, and you should investigate that before turning to measures like in the first post. Use an app like Wake Lock Detector or Better Battery Stats to check what is draining your battery.

I don't actually have a Note 3. Still on Note II but I check in here for feedback.
I would suggest people to purchase the Android Tuner app. It ain't cheap unless u buy it in a sale, but it crams many utilities into one program meaning you don't have to run several different apps. These include battery information/tweaks, overclock/undervolt, ram management, screen off tweaks like disable data or wifi when there's no network activity such as streaming music, backup options like titanium pro, etc etc and much much more of varying complexity depending on how far you want to delve into it.
All in all, a wonderful app and worth every penny.

when you turn off
"Auto Sync"
or enable

does it mean I would no longer get notifications for WhatsApp, Twitter, Gmail?

Galaxy S6 Not displaying correct battery.

I have had this issue for a while and have been switching roms in search for a solution. My phone is draining battery no matter what rom I am using, but when I instert the charger, the battery instantly jumps up about 15-40% depending on how low it is. Does anybody know what causes this and how to fix it.
SM-G920i
Both Xtrestolite Deodex 6.0.1 and Xtralite Deodex 6.0.1
Pretty sure both roms use Arter 97 kernel.
Any help would be appreciated
Did you try to recalibrate it? Also, you should use Greenify to help you reduce battery drain while phone is not being used.

Here is a good guide which shows you how to do it. It's helped me, so hopefully it will help you as well!
Re-calibrate your battery,there are a few on the play store i used it each time i install a new rom (not needed for updates really). They do require root though. Also samsung introduce a feature which when your battery drain there willing be atleast 10% of battery remaining even though the phone shut down. This is an emergency feature and allows you to send or make a call with the last 10%

Thanks for everyones help, took the phone to Samsung with a proof of purchase and got a new one on the spot. Really happy with my expoerince.

Worth rooting? Can it improve my battery life?

Hey guys! Been getting around 4h SOT as highest on my device, AOD turned off, 30-50 % brightness, fhd+ and dark theme.
Can get through the day but can't get a minute more than 4h sot which seems weird.
It's not that I think the battery life is absolute ****, I'm okay with it, the thing that sort of "bothers" me is that i see people getting like 6-10h SOT on like 2 days of charge which seems unbelievable to me.
Now on to the question,
is my utterly **** 4g signal preventing me from reaching 6-7 h SOT or is it just that I'm "unlucky" with the battery lottery.
Is it fair to expect a 6-7h SOT if i do decide to root and flash something like a notorious kernel and a rom?
Which I know will permanently void my warranty.
Or should I return the device and swap it out for either another s8+ or something like a g6?
I hope I don't seem too much of a brat ****face but I did lay out tons of cash for this phone, which other than the battery I am incredibly impressed by.
Thank you guys for keeping this forum running, it's been a lifesaver!

Most of these 6-10 hours of sot is nonsense as most of these people don't even use the phone properly only leaving the screen on so that sot would increase rather than using it properly like watching YouTube having a decent brightness etc... Just use your phone as much as you like stop thinking about battery life if it's really a problem get a powerbank. Me my self if I'm at work I use a lot of GPS as I need to travel and I have my screen turned of as I listen to Google maps rather look this will put me at around 3 to 4 hours of SOT or more sometimes depending how much I use the screen. But when I'm at home I use the phone non stop and I get around 5 -7 I always use full brightest all the time full res gaming sometimes youtube etc as you can see the people who get 6 to 10 they don't even use the phone that much so is there a point for them to have this phone if they don't use it to full potential no they might as well get a cheap phone.
Edit:
The only reason I would suggest rooting is if you want to play around with the phone like having a different kernel that allows to change voltage, speed etc

This, i can get 20hr sot on my mate 9 if i leave it with screen on, take in account SOT means NOTHING, it just one measure that can be easily manipulated.
I use my phone the way i use and i only judge by the end of the day, how much perfect left and what took the most of my battery life, without caring about SOT at all.
Just now i was traveling to Budapest and made ton of photos and videos with my DSLR and the Mate 9, on sunny days your brightness will be up, shooting 4K videos and taking pictures, using GPS google maps, will make your SOT low, does that mean your battery life is bad? NOT AT ALL
Stop caring about sot and use GSAM monitoring up to understand if there is a rogue app.
I have the S8+ and I see that they have figured out how to root the Snapdragon version. I am not really pressed to root my phone.
The 1st time I used the phone, which was a weekend and mostly WiFi, I got over 6 hours of screen time. However on my work days where I use mostly LTE service and I'm inside an office building, I may only have 3-4 hours of screen time but I will make it home with almost 50% of battery life.
I'm no longer concerned with screen time. If my phone can get me through a full day, then I'm happy with it.

Firstly,
I fully agree with @Derpling post above .( His last paragraph..)
Also SOT, now days, means nothing to me.!
Many years back, i used to be obsessed
with benchmark, battery usage, performance etc.
I also use to root all my device's.
However, presently i have stop been " obsessed"
and accept what is reasonable/acceptable.
eg. battery usage including SOT.
prefomance and stop rooting.
There is plenty work arounds available.
Presently, what i do
is i have a few good battery
apps... Betterbattery, Wakelock detector,
Gsam, I enabled these apps with ADB, to get them working. No root. (Very straightforward one or two liner commands, that's all.)
If i have a rogue app, and my battery use " suffers" i use these apps to id the app. and sort app out accordingly.
eg clear cache /data or uninstall.
Lastly i read online that presently,
more devs are
using " other alternatives" than root.
eg ADB...
to give you similar end results.
Bottom line... I found that in most cases
rooting a device just
creates other/more issues.!.. to fix.!
Now days, for me to root my device ( if ever again)
i must have a very, very good reason to root.
Good luck

You so right about root, there is a workaround to everything tbh, i use the Mate 9 without root and it's the closest phone in my opinion to perfection, no tweaks needed.
Geekbench SOT all of it are just numbers as it means nothing.

I think this is your problem, not the battery. One of the biggest battery killers on any device is a weak signal as the phone will push more power to the radio to try and find a better one (not exactly what happens, but there or thereabouts). Rotting won't change that.
Have you tried switching to 3G only, does that make a difference? Does it differ when you spend time in an area with a better signal?

The problem with my service signal is just temporary, I've been working for the summer but I'm moving back to the university tonight, there I have full 4g and 3g signal so hopefully this will change, however I have settled down a bit with the phone and I'm pretty happy with the battery now, 4h sot is not bad
yea rooting aint the solution
try gsam, wakelock detector, etc to detect the rogue app
imho you don't need root to improve your battery life, i'm achieving 5hr SOT easily with brightness 50%, AOD on and resolution WQHD+, all you need is to disable some of the preinstalled packages, do a bit of research to find out which ones can be disabled without a risk, then you will be good to go pm me if you need an assistance
I think your battery preformance is most likely to some apps or how you use it, I can say from expariance and experemanting with my S8+ that SOT and battery over all can shift.
I haven't rooted since im using samsung pay and haven't had a real need for root yet. but have tried a couple of diff apps and tests to max my battery but found that non off it really saves battery, quite the opposite.
I have tried substrantium to go all black in the phone (cus we have Amoled) but my battery life got worse
tried nova launcer to get some preformance boost and also black down the theme, but nova still suffers from battey drain issues (had same problem with my HTC10)
have disabled alot of services like bixby etc with BK Plugin. but made no big diff.
So after having the phone since launch and mixing and matching stuff to see if I could squeese a little more life out of an already good phone, I got to conclution that Samsung has done a good job in optimizing the S8+.
The stock launcher is fast and efficent, the built in "cleaning" program works well in shuting down unused apps etc. and running the phone with no extras and not tweking anything special or trying to get the phone as black as possible, I can go about 2 full days with normal use.
If you have the Snapdragon, battery life will decrease, by 20%.
I switched from a Verizon S8 to an unlocked S8+ and imo not having any of the added bloatware makes a difference. On my S8 I could make it through a whole day but my battery would be down under 10%. I know the S8 plus has a bigger battery but I go to bed with 30-40% of battery life.
I run my phone starting at 4:45am with a gym work out and I'm in bed by 11pm. My usage is mostly lte except for when I'm home. My SOT is always 5 hours or more.

Very limited SOT with OP6 128gb

Using Snapchat with 4G, is location, nfc and bluetooth also turned on?
That would explain the bad battery.
Snapchat is a battery hog, maybe also using some facebook services that you allowed location on and GPS is turned on.
I get around 6h SOT on 4G constant, no facebook permissions and not using snapchat.
Hi,
Thank you for the fast response. I have location turned on because of snapmaps so I will turn that off and limit some of Snapchat's permissions. Is there anything else that someone can suggest please it is crucial for me that my phone lasts all day because eventhough I dedicate quite a lot to Snapchat I also need it for word and Samsung internet for at least 2h each day.
Thank you again
Reduce your time on Snapchat and it'll last longer.
I know Snapchat drains my battery but it's the standby that is killing me and I already have optimised the apps and have Greenify but it seems so far that turning off location has helped quite a bit with general SOT so thank you. Also with Snapchat I only used it for 45mins and I know that it drain a lot but it just goes down too fast in general.

You don't generally need Greenify in Oreo and Pie, since they optimise apps pretty nicely on it's own.
Rather turn on advanced optimizations, look at the permission you gave to different apps (those also include the Gapps, they take too much advantage of all the permissions you give to the each app).
Also do check if you have Wifi scanning always on in the advanced wifi settings, that also lessens a battery by a margin.
Face unlock also reduces the SOT of the phone in my practice.
Some of the advices I saw on the forum, and mainly they work for me.
Also, if Gapps are spending loads of battery go to the recovery and wipe cache, let it rebuild cache with a charge or two and see if there are any results.
Thank you, I have cleared the cache and am letting it rebuild. The SoT now actually seems pretty normal just my phone tends to use 2-3% and hour on standby which doesn't seem normal. Thank you for your help though.
@echo246 Bro,
Move to stock. I am also using 128Gb variant and unlocked, wiped and moved back to stock using mega-unbrick tool. I am on OB3 pie and now I am getting 5 hr SOT + 2 days standby time in pure stock. use the stock battery optimizing features. Don't use any 3rd party app since it need to run in the back ground always to get the result. But then the result will be reverse. Also, don't be too curious and open the phone every 1 minute to check weather the battery is draining or not. Let it sleep. Be patient for one or two full battery circle (100% to 1%) get the result. You will get it. I am also in dual SIM always on 4G, location is in "ON" status. No 3rd party apps using for battery saving. Pure stock is always best and most suitable for every phone. as it made exclusively for that phone
I opened "apps" under settings and went through each and every app + system processes after the end of the first battery circle and which ever process or app used more battery, restricted it's back ground battery usage also all the installed apps too. So now no head ache. getting whats app notification even after optimised it. Not using chrome. using samsung beta browser.
Hi,
Thanks this is great thanks. I need Google pay though I tried what the other suggested and 36mins SoT with 3 hours on standby with a normal brightness without power saving mode on is unheard of for me. Thank you so far but is there anyway to make Snapchat more efficient?

I don't know whether you have replied to me or not. Anyway I assume so and replying.
Sorry I am not a snapchat user. I knew that always Facebook and whatsapp consuming more battery since it is running on background. But if you do anything, you won't get proper notifications. Only way for restricting background service is rooting. So forget all those, let the phone run as it is. OP6 is having a learning system how we use apps and accordingly it will distribute the battery. So let it learn from your usage and it will restrict itself.
(Bro, I was also a SOT + standby hunter like you, but now learned to leave everything to phone itself by controlling unwanted eagerness)
Yeah thanks by limiting the WiFi settings on not to scan and turning off location I have amazing standby now and my SoT without even having power saving on is a lot better now. Most of my problems come from Snapchat anyway but they are rewriting the very old and slow app ATM. Thank you
I have analyzed it and it turns out it is just Snapchat while using it 30 mins of using it and I'm down to 77% and I have used nothing else. Hope that snap Inc get the fix in faster coz they started the rewrite of the android code a year ago so hopefully it is done soon.
Some days I get 15hrs SOT without charging for 3 days. It all depends on how heavily your using the device
I also guess it depends on what apps you use because yesterday I had to do lots of research on my phone (I am a student which is why I need good phone battery and also why I use snapchat so much) and without power saving mode on I used 7% battery an hour (on Samsung Internet). My standby is now amazing because greenify just force closes snapchat now whenever my phone is off and when using snapchat away from home I turn location off (snapmaps) and used every optimisation for it possible. This has fixed that problem really well thank you. Yesterday I used snapchat and Samsung Internet and Excel and YouTube quite a lot and I got 5hrs SoT with only using power saving below 50% and with 14hrs standby. This therefore concludes that snapchat is a killer for every single android phone in existence (verified this on my old S6, my friends S6 edge, a S7 edge, a OP 5 and a Huawei P20 Pro). Thank you for all your help and if someone finds a new way to further improve this, then please also share your trick

I don't have anything special enabled. I just turn data off when I'm not using it, I turn location off when it's not needed. This also includes me playing Clash Royale for at least 3 hours a day sometimes more. When you're using SnapChat and your data you're also using your camera and location. GPS is one of the most battery hogging pieces of hardware on your phone. Right now I'm pushing 6 hours of SOT and I haven't charged my phone in over 24 hours and it's looking like I have 13 more hours left on my battery.

Best battery (SOT) with stock kernel?

Anyone have better battery life on stock kernel than on any custom kernel?

Yup, haven't had a custom kernel beat my SoT and idle drain, and tried most of them. Including wakelock blocking, underclocking, etc. Stock remains best by far, here.
Ymmv and sure some kernel fans will chime in and claim completely otherwise, and that's just fine :good:
For now enjoying 10+ hours of SoT and draining 3% per night being idle using the amazing stock kernel
I'm getting about the same, MAYBE a little better on EX Kernel. I use the custom kennel for features usually.
* Increase vibration strength
* Lower minimum MHz for less per drain when idle
* Increase Mac sound volume
* Disable swap file and Zram
* Increase read ahead to 2048kb (ideal with 32gb or more storage)
With the 7 pro I'm getting better battery then my op6 and I have forced 90hz all apps enabled 24/7 and resolution set to auto switch.
i do kernel tweaking on my own but not a custom kernel. Im on the latest h2os and i get 9 hours sot average. idle drain overnight for 8 hours is about 2%
Personally I don't run a custom kernel for power savings, I run it for wireguard support. The best way I've found to increase battery life and reduce idle drain is running xXx magisk ROM and debloating the crap out of the OS
Yeah, best battery and performance balance is the stock kernel.
Stock kernel...I don't need to look at the screen for 10 hours...doing what I do is more then enough to last for more than a day...
just hit 50% battery and I'm at over 6 hours screen on time
2 days 5 hours off charger with 7 hours screen time.
I don't know how some of you can achieve 10h SoT I literally tried everything - all kernels, debloaters, used Swifted to force most of apps to run in dark/black mode, used Automate to toggle off wifi/BT/kill unused apps that use resources in background (like fb etc), some magisk modules, kernel tweaks - I did all of that with all sorts of combinations (not all at once) and basically I couldn't improve bettery life by any noticeable margin, getting 6, sometimes 7 SoT, my goal was 8-8,5.
I don't any heavy lifting - main usage is Hangouts, Gmail, Facebook (maybe that is the killer?), Messenger, Chrome and sometimes other (telegram etc) - Never any gaming nor heavy programs.

Yup, haven't had a custom kernel beat my SoT and idle drain, and tried most of them. Including wakelock blocking, underclocking, etc. Stock remains best by far, here.
Ymmv and sure some kernel fans will chime in and claim completely otherwise, and that's just fine :good:
For now enjoying 10+ hours of SoT and draining 3% per night being idle using the amazing stock kernel

I'd try sticking to the stock kernel, the problem is that OTG doesn't work properly.

Exactly what doesn't work properly? Can't find any peculiarities.

I think some of those messaging apps (or ones that require syncing or wait for push notifications) are the cause.
You wont see the battery page showing that they consume so much battery because in a way they dont (as they are not in the foreground or doing any heavy computation). But i found that these apps prevent the phone from deep sleep.
You can find out by using things like Better battery status to see the wakelock/alarms of those apps. Some of apps wake up the divice periodically so frequently....
But on the other hand if you want to get notifications from an app and it is poorly designed (drains unnecessary amount battery), there is no way to avoid it. But if you just use jt occasionally and dont need timely notification, try using Servicely to disable wakelock/services of the app (requires root and may break the app, but you can just enable those disabled things to restore the app).

Yeah I suspected that as well and did track Wakelocks. I used Automate to kill Messenger and FB in background when the screen is off, also tried few other tricks and amount of % of deep sleep while screen is of was better - starting from 30% awake while screen off to as low as less than 10% but... Battery train in idle was the same and generally battery life didn't improve at all... Strange but True. That's why I went back to all stock without any tricks..

hummm...well right now im on blu_spark and this is the best battery life i am getting. My set up is described here:
https://forum.xda-developers.com/oneplus-7-pro/development/kernel-t3944179/post79844206
i think im stuck in the same shoe as you cus i rely on Wechat,google sync and a Bluetooth fitness band so the device is going to use quite a bit battery but i managed to get this far...
And battery life is what i require most out of a phone lol
here is a screen shot of battery usesage, its still early in the day but.
I expect screen on consumption will go to about 7.5~8% / hour when the day goes by, like usual.
One interesting thing is that, lol, i never tried stock kernel lol And seeing (in this thread) how people get good sot with stock kernel makes me wanna try it lol will give it a shot over the weekend

Well yours stats look great, I would like to have stats like that as you said, using BT devices connected and messaging app I know I will not hit crazy SoT but still I want a bit better cause as you said battery is like too 1 priority for me I see we are very similar users thanks, in fact I didn't try blue-spark so far, I will give it a shot! I know standy drain will be laso related to Wi-Fi / 4g coverage (low signal = big drain) but I don't think I have such bad signal so I won't to get at least not more that 1% idlle drain per hour and 8-9% on screen and I'm good.
BTW what's your screen brightness usually?

yea lol our needs are very similar.
I just set screen brightness to auto, which changes between 30% ~ 50% when im indoor, whihc is like 90% of time. Then the rest is outdoor at noon lunch time during which screen goes to full brightness for a while.
Oh i also use OLED friendly wall papers and black theme in apps if available.
Ok so your screen brightness and setting (dark theme etc) is same as mine, so this is trsnge why I'm getting almost 2x worse drain... Must try this kernel.

i also forgot to mention that, with PlusBeat, the screen off drain goes up to 1.2 per hour.....and that is because of the wakeups...so i disabled it lol
7+ hours
