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?

Battery drain while idle

Is anyone having issues with battery drain while not using their phone? My wife and I both have noticed pretty good battery drain while we're not using our phones. Going into settings and checking under the battery menu, all we show is phone idle. I've adjusted all my settings to be as battery friendly as possible including turning of wifi and mobile data, minimum brightness, 30 second screen time out, constantly clearing my recents, black wallpapers, daydream off. We're still losing battery life pretty quickly and for the life of me I can't figure it out.

Does anyone have anything to add to this?

I seemed to incur significant standby drain because I disabled some apps. I just reenabled them this morning. Still need to keep an eye on things, but I will copy my days results from the other thread. To see more details on what has been going on, check the other thread.
Right now I am at 66% with 2:05 SOT and 16 hours since unplugging. The Android OS, held awake, and Google Play Services are all somewhat reduced.

As far as disabling apps, the only thing I've disabled are the vzw apps and also the Amazon apps. There's a lot there that I don't know what they are so I just left them alone.
As far as my idle time is concerned, it had gotten a little bit better, but it is nowhere even close to what I could get out of my nexus 6. When I'm actually using the phone, the battery drains pretty quickly as well. I installed gsam battery monitor after reading through the thread that you posted above. I figure I'll need to wait a couple of days to get a true feedback from that app. Once it stabilizes, I'll report back what it says.

I have recently noticed that I get drain when I use Google (now) and/or Chrome. I don't use either too much so I am still investigating. When I use them I get a lot of held awake time in GSAM and a lot of Google Play Services and Android OS battery usage in the native battery usage app. I have to stop the apps and reboot to get the drain to stop. At least that is what is seems like at this point. Still messing around with it. If you use those apps a lot it may be a pain to deal with. If it is one or the other, hopefully an update will fix the issue.

I don't have google now activated, but I do use chrome. I don't see out rubbing in any background services though.

I did forget to mention that I revived nova launcher and all apps associated with it, (tesla unread, nova prime, unused icon packs), I also uninstalled any apps that I have not been using or rarely use.
Having said that, i did give google maps full permissions, went back to the stock launcher that came with the phone, and I did keep all my disabled apps....disabled. I charged my battery to 100%. I pulled my phone off the charger and it took over 30 minutes for the battery to get below 100%. I just got home about 15 minutes ago, and all I've done is Check my email and reply this post and my battery has dropped 5%. It hasn't even been 10 minutes. That's pretty bad. That would equate to roughly 30% an hour.
I'll keep updating as i search for things. I'll try dialing chrome and see what happens.

Very limited SOT with OP6 128gb

Hi,
I am running OOS 5.1.11 with xxxNoLimits and radioactive kernel all freshly installed from scratch (my phone was wiped and oem locked then unlocked again). I still only manage to get 2hrs of SOT which is absolutely awful. Please help me
Attached is the battery usage graph.
Kind regard and thanks for any help.

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

15 HR SOT with 3 days standby?????????
Any changes?
Can you tell us how? So that we can also enable so....

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.

Finding battery drain

Hi,
I have a Note 20 Ultra that doesn't see a whole lot of use. I have a few apps on it, mostly stuff for my smart lights and a few other things. I don't run push on anything and the apps that I have on the Note 20 are the same that I had on my old Note 8.
Lately my phone has spent a lot of time sitting because my job gave me a phone that I use pretty much exclusively during the week. I've noticed that in spite of the lack of apps on the phone and the lack of use, I lose somewhere between 15 and 20 percent of the battery per day, with nothing done to it.
I'm at a loss as to what's causing it. I check the battery app in settings and it shows me nothing useful. I have put unused apps to sleep turned on and have added a few apps to the sleeping apps section. I was wondering if there is any non-rooted way to figure out what is causing the battery drain and to fix it.
Before I had this phone, I had a Note 8. That phone was my absolute favorite phone. I loved that phone. It had a great camera, good screen, and in spite of having quite a few more apps on it, it did much better on battery than this Note 20 does. Between the battery suck and the lack of any useful macro on the camera, this ranks near the absolute bottom of the list of my favorite phones. I'm ready to have Verizon turn on my Note 8 and sell this thing on craigslist. I wish that I'd never gotten this thing but as long as I have it, I'd at least try to do something about the battery drain when just sitting on a table doing nothing other than sitting on a table.

When I had some unexplained battery consumption I used Safe Mode which helped.
Put the phone in Safe Mode which disables your downloaded app's but let's your stock app's keep working. If the issues stop then this highlights a downloaded app as the possible issue. Come out of Safe Mode and start deleting your most recent downloaded app's one at a time until it stops. https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/

Thanks. I've never understood why they don't make it easier to identify what apps are causing problems. That battery app is pretty useless. You wouldn't know by looking at it that I was having any problems at all.

The last few years I have a battery drain between 0.7% and 0.8% per hour, when phone "sleeps" next to me during the night. I use free Gsam battery monitor to check. So your daily "use" while sleeping seems normal. 24 times 0.8 equals that. With ca 20%/day
I use Samsung Notes for years and years and it always comes to that average. Wifi, Bluteooth, Radio, and all other possible options left ON.
Switching them all off or airplane mode, makes no difference at all.
