S6 Battery Life - Terrible

I've been using the TMO S6 for a couple weeks and my battery life is terrible.
I have used greenery to hibernate everything I can, but as you can see in the attached picture the Android system is running overtime. I am lucky if I get 4 hrs of battery time. I also have the screen brightness set to less than 50%.
Any suggestions would be greatly appreciated!

I have no idea why google thought it was a good idea to make battery stats less accessible in kitkat and above, so it's hard to find what causes it. It's probably easiest to factory reset and start clean and then start adding a few apps at a time, to see if you have one misbehaving one

Thanks. I am able to see the apps and utilization using gsam battery app, but unable to look at which android system apps are draining/running, as per the picture.

Turn off WiFi calling and voLte

The problem is that when app X hold a wakelock it doesn't show up under app X but under Android System!

I agree, battery life in general is a huge step back from the S5.

Factory reset then do these two. Also, disable T-Mobile bloat then use Greenify or Shut App.
I can get about a day and a half or two days battery with very minimal use. Don't expect to get more than 4 hours screen on time with this phone. Average is probably around 3.5-4.5 hours but you SHOULD get at least a full day's use with it.

Wifi calling pretty important for some of us

Hi guys I'm using s6 for few days ...battery drains too quickly. ..pls help me need help ...after one call or one song battery drains 2-3% ...I'm too upset pls temme what to do ...would be great if ul help

Battery drain fix

Noticing your Galaxy S6 battery is draining too fast? This thread can help.
Part of the problem lies within a memory leak which is a known problem that Samsung is aware of and is reportedly patching in an upcoming update.
The other issue is Samsung attempts to load everything into memory and run several services in the background as well as hard loading the phone with bloatware.
Here is how I gained 30% better battery performance. Guaranteed
*Prerequisites
*Need to be rooted for every tip to work.
1. Disable anything you consider bloatware
2. Go to settings then application manager and disable both ANT radio service apps. You don't need this. Causes massive battery drain. Google it if you don't believe me.
3. Go to the app store and download "Servicely" from Franco. Paid app but worth the money...trust me. (Need root)
4. Once in servicely add running services and apps to your hit list, choose start at boot and run hit list while screen is off.
5. Reboot your phone. Give your phone a full charge and see the difference
Attached is a screenshot of realistic usage. I was on a poor lte signal for 9 hours and conducted several calls and used my phone moderately heavy. As you can see i got through my entire work day and still have 6 hours left at moderately heavy use.
Remember, this is realistic. I could have shown you a screenshot showing 18 hours left after only using it 1 hour. What I'm showing is a legit 9 hours of usage. Before I made these tweaks I would be at 10% battery or less after nine hours of the same usage.
Post your screenshots after 24-48 hours and let's see how much you are saving.
Follow me on twitter @bash_array

I decided to uninstall ANT. Not sure if its just me, but after just a few hours I think I can tell a difference already. The battery isn't just dropping like it was, especially when idle. I'll post my results from my full day tomorrow.

Awesome. Let all of us know how your battery drain is doing tomorrow

Thanks for the tip, it's funny I installed the Sac23 rom which is pretty debloated, I'd assumed this ant radio would be removed but never really checked, surely enough it's still there and active.
My battery has been noticibly better with Sac23 rom from stock but looking forward to seeing the increased benefits of disabling ANT+.

Are these the only 2 ANT apps we need to disable?

Don't worry about battery life until 2 week after !!!!

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

[OOS 5.1.8] Battery life got really bad somehow

As I've gotten my new oneplus 6, battery life was amazing. I got around 7-8 hours of sot (and average use) with one cycle.
Now I'm on 5.1.8 and with the same usage I get only around 3-4 hours sot. Only thing that I've changed over the weeks; I installed xposed. I don't know if this is the issue, cause I only ran like 3 modules with it (Greenify, Snaptools and NSFW Gboard)
Something else to say, my op6 is heating up more then it should be recently. Like I'm only using whatsapp and instagram, and suddenly it becomes uncomfortable warm.
In settings I also made all battery improvements, given in a thread here.
Can someone imagine what could be the problem? Or does someone have such an issue also? I uploaded some screens in attachments, maybe this is helpful.
Thank's!

Sometimes it can take a few days for a new update to settle down. If it keeps up, you might reflash. Also, check for rogue apps and wakelocks, which can flare back into life sometimes when you update. I have not noticed any real difference in battery life.

It hasnt made a difference imo for my device anyway. From changelog nothing should affect battery tbh. Maybe wakelocks or something plus running xposed with modules is never good from experience

Well I'm on 4G most of the day, I think this makes a difference because I only get such good results like 7 hrs sot when I'm on wifi. With Airplane Mode enabled I lose about 4% over night, I think this is normal or?

Noticed this as well with the update...
Even clean flashed

I have the same battery life as all the other part builds. Actually better since I just added ex kennel.
I stay on data, never WiFi since I'm on T-Mobile with unlimited and never get throttled. I loose about 2% overnight (about 7 hours) though I do keep my syncing under control. 1 email account is set for 3 hours, work is push, all under Google account is turned off since I only need calendar and contacts syncing when I make a new entry so I just manually turn sync on then back off. And I turn all background data off for everything other then what I need like messaging apps and email, Google app and that about it. Nothing to crazy but why let things sync constantly when there's nothing to sync?

For me, definitely thought 5.1.6 was the best for battery life.
Have you tried going into recovery and wiping cache? Worked for me.

6+ SOT on all 3 builds so far.

Google App Causing severe battery drain??

Anyone else seeing this? My Google App is causing severe battery drain. It's been off the charger for 3 hours, sot is 1:52 and battery is at 85%. Google is accounting for 17.4% of drain and only active for 6 minutes and background for 12h7m. I have it set to sleep when not in use. I was watching youtube this morning for 14 minutes and it only accounted for 1.3% drain.
Yesterday it accounted for 20.3% drain and only active for 6m and background 13h 21 m. Day before that 11.5% with active 7m and background 8h 14m.
This is weird. Coming from a Pixel 4XL and didn't see this much battery drain with so little use.

Haven't noticed that on the Note 20 Ultra but on my LG V60 it was about as bad as that. I have installed Nap Time by Francisco Franco which puts the phone into a deeper doze. It's a root app but can be used without root with a few adb commands. It's one of the first apps I install on all my phones.

Has it been doing that since you got it? How long have you had it? Because usually Google is saving a lot of your stuff and creating backups in the background but you can deny background activity by going into the app and ticking the slider over to deny background activity but that might preven automatic backups and saves.

I've had it a week and a half and it's been doing that since day one when I look at history. It takes as much as 25% on some days. I cleared the cache today and hoping that may help.
It's dropped 4% since I posted and I haven't used the phone at all. That's in about 20 minutes.

That's not normal.. is there any updates to that specific app or able to tap uninstall on it to roll it back to a possible previous version?
Edit: this is the screen I'm talking about to stop background activity.
I guess it's still not showing the pictures that are being uploaded.. I'm going to talk to the owner.

I'll try rolling back any updates, but I do see when I do a general internet search that other people have had the problem with Android 10 and Samsung devices. Most have fixed it by disabling the app. But that's not an option I want to take. LOL
I've cleared cache and rebooted. I'll see if I still see a large battery drain. If so, I'll uninstall and reinstall and see if that fixes it.

By the way, do you have a ton of apps and pictures and all kinds of stuff on the phone? Because if you do the carrier's don't give very fast upload speeds and if it's trying to save a ton of data it's definitely going to take quite a while on carrier data.. I'd use a business or someone's wifi if possible so it can do it quickly.

Never tried naptime is it any good?
I have package pro and killallapps installed so would i be able to use naptime along with these?
Also is it just one click does it or do you have to do your own apps to deep sleep
Thanks

I have a lot of apps disabled and yes you can still use it, don't know anything about kilallapps though. If I charge my phone to 100% before going to bed and lay it on the table until morning in 10 hours it won't lose 5%. depending on what apps you have installed may not be quite the same. And yes it puts the phone into a deep sleep. You can have it turn bluetooth, wifi and others off while in doze
