Hi everyone , I'm new in the community but I already found that this is one of the best phone forums online , normally you come here for help because you have a problem right ? But today I'm just here to give an advice, I notice that many people complain about the battery life on their new phones , I had the same issue with my note 5 , I saw a video on YouTube and the phone showed an estimation of battery usage of 18hours while mine only showed 9 , I immediately thought that my phone was broken or something until a month later I realized that I was getting more than 20 hours of battery usage , when we use a phone for the first 3-5 days ( specially android) we can't expect it to be fully optimized because it's still learning your behavior and phone usage, just by installing a new app your making your phone to "learn to do something new" when I got my s7 edge I didn't expected to have great battery life , I was constantly installing and removing apps , flashing Roms and trying themes and etc. Now after a month later I use my phone on a pretty standard routine , I used package disabled but it only made my phone laggy and slower , so I decided to use my phone on the stock way , I running all stock , ( only disabled the apps that come with the phone that I don't use like power point , Samsung gear and health...) and after I did this I noticed a huge bump on battery life , I went from 12 hour of usage and 4:30-5hours of SOT to 30hours of usage and 8hours of SOT
After installing a custom/stock rom make sure to drain the battery completely just once to calibrate it !
I can never get more than 6 hrs sot.. Gonna follow your tips and write back in a week or so. Thanks for sharing!

Feel free to use package disabler, it was a lifesaver to me with my note 5 but not on the s7 , but other users report that has been really helpful other thing you could try even that the impact will be minimal is using a dark theme ,
Also don't update to the newer firmware if on Exynos. Seems to hit battery life by 25% or more as android system goes from around 5% to 15-20% battery usage.

with newer firmware you mean the may update?
with me it was the other thing around, in the beginning it was quite good but now, its worse. is it because of the bright sunlight or the phone getting hot because it was around 30 degrees almost?
you see...screen on time about 2 hours
most active battery drainer, android itself
Only way for me to get 4 hrs of sot i have to plug in to charge and disconnect before i get to 90 cause then it seems to thing its fully charged and battery meter resets (on battery).

The thing is, I have disabled half of the system already, but it just feels like it's doing even worse than before so I'm leaning back on running stock again.
Yes original firmware much better battery than the update

It didn't work either to me , this is what I think , it may sound stupid but it could be the true cause , I think when you use an app like package disabler to disable things on your phone and then you accidentally touch to open the app or setting disabled the phone will think "what's going on here" why is this disabled? And it maybe tries to access/ open the package again and again causing it to actually drain battery !, You could a cache wipe , it worked for me , I follow all guides to extend battery life using package disabler, custom rom , flashing zips to delete bloatware but none of them worked for me , instead I went all stock ,and after installing the stock rom I did a factory reset and them the cache wipe, it worked flawless to me , the phone now works like a charm , no overheating (maybe I don't feel it because I got a case ) but the point is try to find your own solution , every s7 edge it's unic, maybe a simple reebok on your phone could resolve all of your problems , and a very important thing !!!!! If you flash a rom /kernel make sure you let your battery drain completely just once to calibrate it!
I wiped nothing, stock rom latest APD1 , aod off now but on sometimes , location on, sync on 3 emails, disabled a few things with ez package disabler. Browsed the net for all the time the screen was on, WiFi on while screen of and on for atleast 2 hrs while using line messenger and used Spotify for around 30 to 40 mins. This is sot and battery usage.
I don't know how u manage to get such bad battery life, swear u guys r fu#*ING about with sh%t too much, let it settle.

Great battery life , you can easily achieve 3 days of battery life and 8-9 hours of SOT I guess which is great for you , just consider yourself in the 5% of people that own a phone with no battery issues , I'm happy with my 8hours of SOT and I could achieve 3days like you just by using WiFi, I use LTE because it's faster were I live but remember that there are people so disappointed with their phones because they want to get the most out of their phones and just can't, may I ask if you are amazed with your battery life or do you own other device that beats the s7 on battery ?
I am amazed, it's as good as, if not better than my previous phone the z3, which was running a custom rom and kernel.
I do consider myself lucky to have the phone run so well right out the box.
Also when I said alot r fu#&ng around with their device, I meant roughly the same as you, I didn't mean to imply their problems r not actually there. I meant as u had said, changing roms, removing apps for new, disabling apps, not letting anything settle, wont give good results in battery life.

Holy smoke, 5+ hrs sot in half of battery. I've been trying to get more than 6 hrs for like a month now with different roms and optimizations, not even close..
I hate to be the voice of cynicism, but we do need to stop this stuff somewhere. The original post is utter nonsense. The suggestion that phones 'learn' your behaviour just simply isn’t how kernels work. There's a very small degree of 'learning' but power management is a very reactive process based on exactly what's happening. The only thing new apps change is what processes are running, and the kernel will instantly scale to do what it 'thinks' is right. Some managers will observe processes for a bit longer and react based on that - but we're talking hours at most, NOT days.
The only credit I'd give to this idea (which seems to be all over XDA for some reason) is that the first few days people use their new shiny phone a lot more than usual, and probably also more than they’d think. They also become far more aware of battery life and will even turn on the screen just to check battery life, which will obviously accumulate batery drain - so the bit about using your phone more is certainly true. But anything about Android being some sort of AI Neural Network app learning extraveganza that learns what you do over several days is (for the most (significant) part) wrong.
Think this is just descending into another battery thread and we have one here already

Ok so i've seen a few threads between here and other websites regarding the Note 3s battery issues but felt the need to make my own as I still haven't found any kind of solution.
I purchased my Note 3 N9005 (I live in the UK) around a month ago and ever since my battery has been terrible ever since. I am basing this on the fact that I have owned a Note 3 twice previously (I managed to get one just after they came out for a reasonable price second hand and also owned one around 6 months ago for a while) and battery life on those two devices were fantastic.
Around a week and a half ago I decided to root and try a couple of roms to see if it would make any difference after making sure it wasn't my SD card causing the problem and couldn't really try anything else. After going from the CMRemix, CM11 and Echoe 5.0 not a great deal changed on each after using each one for a couple of days, every day my battery gets hammered by 'android system' and 'android os'. After seeing a post about it I have gone back to stock touchwiz using the 4.4.2 Nordic firmware. This made no difference either.
I have posted some pictures of my battery life since getting up this morning. I always have sync turned off and my screen is always just above the minimum brightness. Im on Wifi a lot between work and home which in theory should use less power. I've been playing contest of champions quite a bit recently which I would expect to be a battery drainer but it is still beaten by my screen and this android system and OS combo. I also don't get why battery dropped around 18% (30 something to the 15% warning) in around 20 minutes which is the red line on the battery graph. Last Friday I went to sleep with my battery on around 78%, when I woke up it had dropped to 42% with no apps left running.
I'm literally out of ideas. I've tried everything i've seen on forums and it hasn't worked. I've owned an S5, m8 and z2 but ended up coming back to a note because they are simply fantastic phones. I am however seriously considering selling this and getting a different phone if I don't figure this out soon though. Can anyone help or is this simply an unsolvable problem caused by horrendous software implementation, or am I being stupid and should be content with 13 hours irregular battery life???

Thats just not normal, try to use app wakelock detector (from playstore) to see what apps are currently running, you can also go to the device app manager and then go to "running apps" and then see what apps are running on backround, that would give you a general idea of where are the battery draining apps. Then all you have to do is to disable/freeze them , using the inbuilt disable option under the app settings or using a third party program like app quarantine (from playstore). Note that i also recommend you disabling apps you dont use , like for example samsung apps etc.

Thanks for the advice. I even ordered a new battery from samsung which arrived this morning but that doesn't seem to have made much difference either. If I hadn't seen similar cases to mine i'd think my phone was broken but honestly I'm starting to think that is down to samsung software and won't ever be fixed. It's a shame because the Note 3 is the best phone i've owned but ill be steering clear of samsung devices in the future

Use Greenify to hibernate apps..it will save ur battery..
Greenify is a big help. Also use Titanium Backup to freeze or uninstall anything with the word 'Samsung' in it that you don't need (they're terrible, in my experience).
Some other things that can help are turning off GPS and Bluetooth when you don't need them, raising your wi-fi scan interval if you typically leave wi-fi on in areas you're not connected, using an app like AutoStarts to control what apps wake up when, and you should check what apps you have auto-syncing, and how often. If you don't need gmail and facebook to sync every 5 minutes (just an example), then change the interval. And unless you spent a good bit of time playing it before you took those screenshots, I would highly recommend ditching that Champions game.
Aside from that, another thing you might want to consider is trying a different kernel. Some kernels are just bad on battery life.
I'm on my original, stock battery, and I get 22-26 hours typically, with moderate usage, and anywhere from 6-10+ hours of screen on time. Right now I'm sitting at 18h5m29s with 5h26m3s screen on, with 27% battery left.

Trying a custom kernel is something else I'd though about. It's crazy that you've got those battery stats. My brightness is always near minimum and I only get 4 hours on a good day. Judging from posts I've read those android os and system percentages are accurate for the note 3 nowadays. I never have sync turned on so that can't be the issue. I've got this phone on ebay now so if I don't sort this out in the next couple of days I'll be moving on unfortunately, bit sad as this is the best phone I've owned

I'm in the same boat. Stock 4.3 with tons of apps frozen, greenify doing its thing and Google Play Services tamed as it was draining the battery. To me everything looks ok in WLD but I have noticed that something called 1013 which is always at the top with most amount of wakes, is that system audio? I also have screen brightness on minimum, powersaving mode on, bluetooth and gps off, sync on and most of the time usually on wifi networks.
I have managed 6hrs screen on before but when using device moderately over 2 days I get 4 hrs screen on time at best, usually 3 or 2.5 hrs.
The 6 hrs was managed when I watched 3 movies in a row, it seems sleep takes more than it should? Wake ups are a problem?

Yeah something has definitely gone wrong at the core of the phones software, especially when different roms and stock firmware builds are making no difference at all. I flashed AEL kernel yesterday so i'm seeing how that goes today. I'll post screenshots when i get home from work, so far my batteries only dropped 10% in 3 hours but thats with 30mins screen on time.
Had similar battery draining issues, I froze Unified Daemon (EUR) this appears to have fixed it.
I have faced this issue after my phone got the last update.
Even the android system was consuming more than the screen.
I removed Google account and put it back again but this time i limited the Google features that do the sync to the required only, gave a full recharge, the second day the android system consumption decrease a bit.
I gave it a full recharge cycle each day for the next 3 days and later it came back to normal.
I hope that helps.

Hi there,
I bought my one plus a month ago, and am getting around 3.5 screen time.
It is disappointing as I see screenshots of people with one plus who are getting 6 -10 hours screen time.
I am on battery saver mode, not using music, whatsApp, wase games or facebook, just a little bit email and browsing.
At night it is not going down a lot, but when I start using the phone, it goes down quite quickly.
(1 percent every 2 minutes, sometimes every minute). It seems to get worse every day.
If I start using GPS or video or music, my battery will be finished by noon.
I replaced the battery, and it is the same.
Attached three screenshots. (Including the night)
Help please?
Thank you!
I share you the same feeling when I see others having impressive battery performance specially screen-on time.
I have exactly the same drain behavior of yours, when my phone in deep sleep its sleep like a baby. but when I wake it its become beast awakening.
I run 3g when I am out and wi-fi at home, also running regular apps, whatsapp,snapchat,2emails,1gmail,instagram,web browsing, auto brightness,greenify. I checked with BBS and WLD but no culprit. I am on stock rom with root for the apps, no system tuning.
So you can see my setup is like most of regular users will do but noticeable difference in term of battery performance. I have no clue
Your battery life is fine, better mine
Who has a lot of SOT usually doesn't turn off/on the screen that much. The secret to achieve a lot of SOT is making long session on the screen (and having few apps, like you). So no worries I'm at 64% now with 1 hour of SOT, but I flash updates (CM 12) everyday and wake up the phone only when I need it, with 1-2 minutes sessions.

That isn't really true, I have over 100 apps installed and I turn my screen off whenever I'm not actually using it. I'm a heavy user. I get roughly six hours of screen on time.

Hi,
Well, at least I am not the only one....
The problem is that it is getting worse every day and now I lose one percent in a minute!
Horrible! I have to charge it twice a day, and I barely use it.
I have no root, am not using any of the apps, only a little bit of browsing, and checking mails.
If I try to use waze for a half of an hour or a little bit of music (max 30min, I get only about 2 hours screen time!
It seems really poor from a brand new battery.
I have no clue what to do, or what is causing it. If anyone have suggestions, i will be glad to hear!
Are you using the stock OPO rom? because I always had a poor battery life, I had all kind of protections to keep battery life but when I saw, from 100 I had 70, it was awful, one solution I saw was to flash one custom kernel, somehow improved my battery life, but the final solution was to use a custom rom, I have experienced better battery life with 5+ roms rather than the ones with 4.x.x, maybe you should taste another android flavor and check if the battery life increases
How hard was it to change the battery? Was it soldered? Where did you get a replacement ?

Hi,
Thanks for your comment.
Sorry, I don't understand much in roms ... I bought the chinese version color os, and changed it in fast boot to cm11.
My cm version is 11.0-xnph44s , android version-4.4.4
I believe this is app related. Some apps keep phones awake. I encountered this problem with my S3 because I have lots of apps. But since I made sure I only install apps I absolutely need in my oneplus, I get a fantastic battery life.

I don't have so many apps , and I installed all of them. I keep closing apps that are running on the background through the settings.
The funny thing is that it is getting worse every day.
Now my battery is going down one percent in 30-60 seconds!
I don't know what to do anymore.
hello guys, i hope you all are having a great day. so my problem is this : as soon as i got the phone, i rooted it ( obviously knox tripped but that doesn't matter to me) i flashed some customs roms, but i didn't like them because the phone was lagging and freezing randomly from time to time with the phone starting to heat in just 5 min or less and the battery life got crappy. Then i decided to flash a stock rom odin, but that didn't change a thing, since the phone still having having heating issues and extreme battery drain. oh yeah, and fast charging doesn't seem to be fast even though the fast charge activated.

Try a factory reset, and do a clean setup (don't restore any apps).. Then just give it like 2 days (the battery usually drains faster the first couple of days).. This same thing happened to me when I got the phone out of the box, rooted it as well after a week because I don't care about knox or warranty, phone was heating and battery draining so fast, I did a factory reset and a clean setup, after 2 days of discharging the phone and charging it to 100%, the battery life got better and stabilized, the heat went away. Now I easily get about 6 hours of SOT with heavy usage (gaming and stuff), and the phone barely gets hot (it only gets hot when I play pokémon Go on 4G because it uses your GPS constantly). I have the exynos version as well.
Edit: Also try Package Disabler Pro (it's paid but it's worth it), it disables all samsung bloatware and some useless services that keep running in the background, it sure helped my phone feel a lot smoother and get even better battery life.

Now I easily get about 6 hours of SOT with heavy usage (gaming and stuff), and the phone barely gets hot (it only gets hot when I play pokémon Go on 4G because it uses your GPS constantly). I have the exynos version as well.
Edit: Also try Package Disabler Pro (it's paid but it's worth it), it disables all samsung bloatware and some useless services that keep running in the background, it sure helped my phone feel a lot smoother and get even better battery life.

the main reason why i rooted my phone is to use titanium backup to restore my whatsapp conversation and to also use Xposed. and okay, i'll leave it stock for 2 days, i won't install a thing. i'll let you know how things are going for me thanks for the reply man

I'd avoid Titanium Backup, just start fresh.. I'm rooted mainly for adaway because I hate ads, I use xposed as well..
Let me know how it ends up

alright man, look : today i checked my phone at 14:48 and it was at 96%, with everything off ( no sync, no background app, just fresh rom ) and now its 22:33 in my country and it's at 90%, thats good right ? or should it be much longer than this ?

You can also go to Settings > Battery > Details and then select apps that you don't always use to 'always save power'. Your stats seem good to me.

how quikcly does your phone starts to get hot ? mine starts to get warm after 5-8min of usage ( wifi on ) is that okay ?it doesnt get that hot, i meann its normal if i watch videos and stuff, right ?
I heard somewhere that when you root S7 it changes the CPU's governor and it starts to lag overheat etc.(only in snapdragon model)

He is using the Exynos version, which does not have this problem. Only the Qualcomm root method results in the cpu governor being changed to performance, causing battery drain and heat.
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.

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.
