Horrible Note 4 Battery Life. Android System Draining Way Too Much Battery.

So I have a T-Mobile Samsung Galaxy Note 4, I got it back in October so yes I have "broken in" the battery. I have checked out several other posts and tried pretty much everything. I've turned off bluetooth, NFC, any and pretty much all useless Samsung features (smart stay, turn over to mute, multi-window), I've got a black wallpaper on for both my home and lock screens, I have greenify AND DU Battery Saver, I ONLY ever use data as I have unlimited data and my building has a shared wifi network which I don't trust, I have tweaked Sync in the settings menu to only sync crucial info from all my accounts (google, facebook, email, whatsapp, etc.). So far the BIGGEST battery drainer is Android System. It is always number one. I've had days where I've decided to push the screen-on time to its limits and have used it nonstop. Screen consumption only ever gets close even if I use my phone nonstop Android System is the biggest offender. I've tried keeping power saving mode on 24/7 but that has not seemed to help at all. I've disabled S Health, S Voice, and several other apps I never use like Google Play Newsstand. I am at the end of my rope I despise this phone for its claim to great battery life but its absolute GARBAGE real world performance. I consider myself lucky to get over 3.5 hours SOT. At this rate I might as well have an iPhone 5. I have no idea what to do.
Here's a list summarizing the things I've done to improve battery life:
Bluetooth off
NFC off
Multi-Window off
All email sync set to Manual
Sync for every account adjusted to isync only crucial info
Pitch Black Wallpaper
Power Saving Mode (Not Ultra Power Saving) switched on about 90% of the time
Using Greenify on all Power-Hungry apps
Closing most apps upon finishing using them
Using DU Battery Saver in order to monitor battery activity
Never use Wifi
No Multi-Window
No Touch Sensitivity
No Side Key Panel
Wifi Calling feature disabled (I never use wifi anyway)
No Download Booster
No Smart Stay
Animations switched off via the Developer Options
Tried using another battery (similar if not identical results)
I'm still getting at the very best if I'm somehow on a miraculous streak of good luck that day: 4 hours of Screen-On Time. It is ALWAYS Android System usually followed by Android OS and then an app or two before Screen (because my SOT is so pathetically terrible)
I love this phone, the display is beautiful, the camera is fantastic, it runs seamlessly (on Nova Launcher that is), BUT I despise the battery life. It has made me resent this phone and I'm seriously considering switching to the iPhone 6 Plus as that has comparable battery life and with it running iOS I doubt the OS would destroy my battery the way Android has been lately. What do you guys do to get such good battery life from this phone? I've tried everything I know!! Please can you help guys?
I'm also attaching screenshots from one of the BETTER days.

I would consider rooting and installing a custom rom, poprock I would recommend for keeping touchwiz.
I don't know.. maybe your battery is the problem.. When I was on stock I had the same issue, but i varied in a weird way. With poprock, battery life has been amazing.

A few people have this issue. I really think it has to do with a corrupt file that was flashed. Maybe no fix but a new phone. If part of the pit file got damaged no fix but samsung.

the battery distribution and the SOT is what I usually get too.. but the usage of 7 hours is too little. I always get over a day..

I'd already seen your thread. It wasn't too helpful for me unfortunately because I'm not rooted. Half the terms you guys were using "Odin'd, pit file, etc." I don't understand at all. I'm running Nova Launcher on this phone. Just typing this comment my battery has dipped from 78% to 74% this is ****ing ridiculous I'm sick of this **** phone I might just switch to iPhone. I'm done with battery raping Android.

I'm in the process of fixing this. I think I may have figured something out. I have been slowly working through freezing applications to figure out what is causing the battery drain. I've made some progress. I really think it is an issue with lollipop system apps.
I am now having a slight dragon from cell standby, but the Android System drain is getting capped. Been in this single charge for 17 hrs and Android system is only 7%
Once I get a bit more firm information I will post my findings.

Some suggestions: check out your Google settings first. Disable Google Now and uncheck their location monitoring settings. Also freeze Facebook (use the website instead). Finally ou can disable sync altogether for a while in case other apps are hammering away through it. Test your battery under each of those conditions. Good luck, be patient, take your time. If your battery is good eventually you'll get to the bottom of it. Use Better Battery Stats to monitor. Most people get fantastic battery life. I rarely use 40% in a day. Over night (8 hours) I lose 2% - that's also a really good thing to watch. If you are draining badly at night, you have major wake locks occurring.

Thanks I'll try some of that but my problem is that I shouldn't have to do all of this crap! God it seems like we HAVE to revert these superphones back to pre 2000 dumb phones in order to get any kind of a decent battery performance from them. Samsung just haaaaaad to make the screen 2K. If they'd kept 1080p it might've been better! I might as well just switch to the iPhone 6 plus if I want ZERO functionality from my big screen phone. God I hate this Note 4 and I'm so jealous of people who don't do anything like this and still get 5-7 hours of SOT with their Note 4's. I'm beginning to think they're full of it honestly.

Nope. Either replace the phone or wipe and start over since u not rooted very little help.

If you're not rooted do this:

If you are scared of root just stay stock rooted. Not a slight at Bacardi. He answers the questions better than us.

I am have the same issue with battery drain from Android System. I have see that issues is there when WiFi is enable the battery drains faster. When WiFi is off and using mobile data it drains normal.

I will be watching this carefully. I have the same issue. Always Android system and Android OS in the top 3 battery drainer. Only, issue I have is I have to use WiFi at home. T-mobile service drops to Edge about a half mile before reaching my neighborhood.

If you click on the Android Systems within the Battery usuage section. It will give you more detail, and show you what services, or packages are using it. The. You can take it from there.

Battery Drain on 9.0 Pie

Hi people,
Can someone give me and opinion of the battery drain with a note 9 on pie?
I bought my Note 9 four days ago and updated to 9.0 pie right out of the box, I think that battery is still optimizing for usage but I find it very bad with battery life and SoT. I'm posting a screenshot, if you have some tips ?

I'm with exynos, 50% brightness display, exynos version, Bluetooth off

You answered your own question! Battery is still optimizing for usage! You have to give it 10 or so days before it battery gets better! Also turn off Wi-Fi, Bluetooth, 4G, Sync, turn the screen off turn everything off lol messing with you 2/3 weeks mine took to settle down!

I'm having the same problem. Android System was waaaaay lower before. It's always at the top of the list now. :/

There's plenty that can be done, especially if you have the exynos version of the phone.
-Unlock bootloader and install Dr Ketan's rom, it is fantastic.
-Then apply endurance kernel.
-Use Magisk manager to apply module: Universal GMS Doze
-Use Mtweaks to apply a few kernel tweaks
I haven't gone this far just yet as I'd like to see how the phone goes without it for a few weeks but you can also install greenify or if you want to really get serious, greenify xposed module. Personally I find the battery life of the note9 to be fantastic but you must keep in mind that the screen is enormous and hi-resolution. Whenever you are using the screen, especially at a high brightness level the battery is going to drain - it can't run on good intentions.
Try turning down the brightness. If you are absolutely serious about battery life over everything else, you can disable auto-sync, remove the official facebook apps if you have them and replace them with faceslim and lite messenger and modify the notification settings.
Doing all of the above and only turning the phone on when you need to make a phone call or use navigation etc should net you an easy 4 days+ of useage but then again, you may as well have bought a $30 powerbank phone.

Tripping Knox hardly sounds like a good idea if I'm honest.
If your Android System is high then something in the background is wrong. You could try clearing cache then give the phone a couple days to settle

Battery life varies significantly with any phone and any version of Android.
Often we assume, wrongly in my opinion that a very large factor in battery life is the version of Android , hence the numerous posts on this forum who wish to or have gone back to Oreo, for reasons I consider delusional.
What apps you have on your phone and how often you use them are significant, playing games that use lots of cpu and gpu is going to impact battery life.
Web browser and YouTube rather less so.
I have experienced lower and higher screen on time and standby time with the same apps and version of Oreo, and Pie (both on beta and released)
I am on Exynos Note 9
Bought and used since release date Aug 24 2018, haven't used so called battery life friendly charging (20% to 80% etc)
Can run battery down to 0% on occasion and charge to 100% using fast charge, often left on charge overnight.
Yes there are some optimisation that may help and I use a few, I couldn't tell how much they help though as just varying usage is a greater factor in my opinion
Battery performance from yesterday
18.5 hours total usage with 9.25 hours screen on time

Question Battery life not as expected

So i got my S21 Ultra a couple of weeks ago and the battery life isn't as good as people tell it to be... I wonder if this is normal or i have a faulty unit
Important: i am running the latest update on my exynos device (february security patch as of the making of this thread)

What do you expect? You have used the phone almost 12 hours, used Samsung Music for nearly 8 hours and still have 78% battery left lol. This is great.

The SoT is pretty crap i can only get 5 to 6 hours if i'm lucky, all i do is watch youtube and netflix and nothing else pretty much, and since SoT is pretty important to me idk if i should wait for an update or get another unit

If you are comparing to a Chinese phone, I would agree that the battery life is not great. Before buying S21 Ultra(exynos), I was using Mi 10T pro. It has better battery performance than S21 Ultra. The other thing that I dislike about would be the heat issue on S21 Ultra. Its horrible.

SOT is only one measure of battery life, the battery still depletes when the screen is off, especially if you're doing something like listening to music for 7 hours......
If you saw the YouTube 'battery drain' tests, the majority are in a room, mobile turned off and on WIFI. They are in constant use with minimal ramping/up down of the processor as they only switch apps every hour. These guys achieve up to 9 hours with constant use in optimal conditions.
If you extrapolate out your current usage you're on for 7 hours with 51 hours total, which is very very strong. People would kill for that endurance
At best you can expect 0.5% an hour drain if you aren't using the phone, but that's if you literally leave it overnight and don't touch it. More likely it'll be between 1-2% depending on usage, so if you calculate you've had roughly 10 hours of screen off, that's about 10% battery that isn't being used on screen on time, which equates to roughly an hour of SOT 'missed out on' if you were just to run the device with the screen on for the sake of it.
If you're truly only concerned about SOT, run a day without music in the background and see the improvement. It's a nonsensical thing to do as that's not how you use your phone, but will get you the numbers you want...
You're also using a high end processor and a large screen with a high refresh rate, it's going to use more juice than a mid range or low end phone. If you send that phone back, someone else is going to be very happy when they get it as their replacement

With my s21 ultta i can easily achieve 10-12hours of sot with browsjng and youtube on wlan with total runtime of 48hours.on mobile data its a good 35% less (also cause of brighter screen outdoors) but Overall its good battery life for me (note im debloated and using Samsung browser with darkmode!!)

I'm doing OK on the battery. Turned off goggle discover on side screen has helped aswell as 5g disabled as I don't have it where I live atm

Yes if you want the same smoothness and a good 10% better battery you can use the 96hz mod

Put brightness on manual. The display eats a lot of the battery. Try to keep it at 50% or less.
Turn off all animations and use dark mode/dark wallpapers. Junk like tic-tok, fb don't help.

Fb is malware, I don't care who or what's on it, it's off limits. Instagram... no way.
Tweeter just as bad as fb. Full boycott on all that junk until they f-f-fade away
Been using manual brightness control for over a year on my 10+. Occasionally I toggle it on but rarely. Going full brightness will greatly reduce OLEDs finite lifespan. Blue goes first... and the burnout isn't even. If I can get 5 years with just a battery change or two, I want it.
So far between Samsung's and Android's weak offerings I have zero incentive to upgrade hardware or firmware

Think how much easier it be to do now...

Has there been testing on the battery effect of different wireless network modes, including while being connected to Wi-Fi?
I understand that 5G uses more battery, but I'm curious how that is affected when you remain connected to Wi-Fi for all data transfers (using 5G just for calls and texts).
Same question for the other network modes, like LTE/3G/2G vs LTE/2G etc. Or also when you are not connected to Wi-Fi.
I can't help worry that some people are getting bad battery life because they have a poor network signal?

Only rough but very little difference between 4g and WiFi when still, and that's in a location with 2 bars signal. Seems like the phone sleeps better with mobile data on.
It's hard to make a direct comparison with WiFi Vs network, as a lot of the network drain is when moving and polling for new antenna. When looking at signal strength, 4g/5g have the same dBm and 3g/2g have the same dBm, but 4g needs less dBm for a higher transfer rate than 3g, so may use less power over time.
Also I don't think 5g is inherently more power hungry than 4g (I may be wrong), again it's just less available and shorter radio waves, and until now 5g has relied on external modems.

Exactly, I wonder if our S21 Ultra is much better with battery life on 5G, because our SoC includes the 5G modem and it's not external?
My desire is to just keep my phone on 5G while I'm at home idle and the phone is connected to home Wi-Fi. I wonder if there is a battery savings to be had if I switch to LTE while I'm at home on Wi-Fi and the phone is just idle.

General Battery life and optimization

During intensive initial days I get 4-5 SOT and 12h use time. This is with mid heavy usage.
My battery starts today attached:
- over 7h music streaming partially on Chromecast partially bt
- over 1h YouTube (45min in browser)
- 40min Teams video call
- over 30min photos and videos in two camera apps
- 1h of Opera browsing
- Gmail, messenger, maps and all other apps in constant synchronization
- last.fm and pebble running in background
From the list you can clearly see that the only stand behavior is connected to AOD which was over 1%/h so I have disabled it.

Hello
As I understand in my daily use, mixed WiFi - 4g, you can reach 5h.30min ost. Maybe is necessary some adjustments on 4g/5g modem, it sucks a little bit of battery WiFi is the best, the graph is linear.
Attached my mixed 4g/WiFi experience, during today. I forgot kill YouTube, I did 2hr screen total. As you can see in WiFi the graph is linear (untill the middle), while on 4g (2nd half), the curve began to drop more steeply.

Starting to learn how to use this phone.

No complains at all. Can't kill the battery in one day. Most of the screen time is at evenings at lower brightness but I do work so it's my natural usage.

After disabling always on screen, 5G, Google tracking and backup I easily get over 6h SOT and less than 40% battery drain during 24h.
Battery is very good and there's no doubt about it.

I get about 3.5h SOT for 80% battery, no 5g, no AOS, dynamic mode, screen 90hz, no gaming, no apps with heavy drain

I lost 3% over 9 hours last night while the phone was on my bedside table,this was the first night,i think the phone is deep sleeping properly?i have restricted quite alot of apps from running in background

7.5+ hours of SOT is possible. Here I reach 7 hours and 13 minutes of SOT from 90% to 8%. Ultra durable mode, no 5G, no mobile data always active in developer options, all WiFi, and Facebook services disabled. Brightness is set to auto.

To those who's looking for compact phone, superb performance, 120hz display, great speaker, and good battery life, go on with Zenfone 8. Here's my SOT on my Zenfone 8 with force 90hz enabled. Cheers

It looks like the last update improves the battery life quite a bit. Only free hours so no hard claims but the impression is heavy.

The one I got today: 30.11.51.67
I have updated the phone at 70% and got brilliant times afterwards. Over 5:15h SOT and 15h since charged with 20% still left.

Could you please tell me how is the standby drain? Is it more than 1%/h during the night sleep?

I get between 1,3 - 1,8 percent during night in deep sleep. Confirmed by AccuBattery.

thank you for the reply, but could you be more specific? the drain you mentioned is per hour or per entire night?

It's per hour.
You can get probably less when switching off connection of data. I am leaving the phone fully ready as I have used it during the day - just put in ultra durable mode.

Jusr for info, after watching a teardown video I realized he battery is actually 3835mah not 4000 !

General (SOT) Leaderboard - post your longest SOT's here 👍🏻

Looking at the OnePlus 10 pro on paper, it has everything you would possibly need to achieve incredible screen on times.
The idea behind this besides some healthy competition is to whittle out the bugs and battery draining apps and habits.... in the hope that we all benefit from the knowledge learned and gathered.

Rules
---------
If you'd like to register an SOT, you will need to provide a screen shot of your battery stats using the stock battery app, clearly showing the up time and screen usage time and app list.
Your OS, kernel if different from stock (no screen shot required)
NOTE*** Without this proof, your name and score won't be added.
That's it
Good luck

Some tips for better battery life.
Change 5G to 4G
Remove Facebook use web based
Remove Facebook messenger use web based
Remove Twitter use web based
Remove any ad based apps pay for the pro version
Turn off gestures like lift to wake
Change from QHD to FHD (No difference)
Allow auto brightness
Turn off WiFi overnight
Turn all updates to manual not auto (play store)
Remove any so you don't use
Change back up to once a month (WhatsApp)
Turn off location history (Google)
Use titanium to remove any system apps you don't need
Don't allow anonymous usage statistics for any app ever.
Don't allow tracking cookies on any website
Use adaway (root needed)
Don't open web pages in Google app (I use Samsung browser)
Don't use xposed.
If you game you will not get high SOT scores, period.
Don't bother with battery saving apps or monitoring apps.
Streamline your apps, if you don't use it, remove it.
Don't allow WiFi scanning (as in letting other apps use it when it's not on)
Never allow personalised ads.
Never allow notifications from websites
Always decline cookies unless your absolutely have to allow some tracking (common sense prevails here)
Optimise as many apps as possible unless it affects performance.
Don't allow apps to remain open in the notification area.
Change your launcher, my preferred launcher is lawn chair and this did actually burn up some battery when compared to the OnePlus launcher.
Don't use live widgets (yes they look cool, but they annihilate your battery)
Live wallpaper, again very cool, but battery burners.
Again! Don't charge overnight, make a note of your percentage then see what it is in the morning, you shouldn't be losing more than 5% really, if you've done well then it'll be reflected here, the good SOT results will follow.
Turn off live read outs of network speed, RAM usage in the status bar.
Turn off NFC unless in use.
Leave location on in quick settings.
Don't overcharge your phone, IE: overnight
Don't allow your phone to fully deplete the battery.
Whatever anyone says, this does 100% damage batteries, there is no argument here and I won't entertain anyone who says otherwise, Ive seen through real life tests what this results in, bloated, inefficient, possibly dangerous lithium batteries.
Keep your phone out the sun.
Keep it out of extreme cold.
Keep your device clean and dust free.
Snapchat, Viber, house party, apps like that tend to use more battery as they don't have great dormancy periods, use them if required and get rid.
Apps like speed test by Ookla tend to have location tracking, similarly they tend to turn themselves on and off when they feel like it, my advice, install test and uninstall.
Allow a couple of battery cycles between tweaking sets, to give you an idea of how much of a difference you've made.
Use BBS to see what is being used, once you've removed problems, remove BBS.
I've just written this from the top of my head so I've probably missed some things, the general idea is to keep your device clean and fresh, remove files / apps / mods / widgets / features you don't need any more.
Keep an eye on apps that misbehave or aren't wanted, index your folders so they aren't a mess.
The more good things you do means the more potentially bad apps you can have on your phone, eg if you really need Facebook, you could keep it so long as you clean up other areas of your phone.
Hope this helps.

I'll put it up as there's none up and a believable time.

Changed over to lawnchair 2 and holy moly the difference has been amazing.
0% lost overnight 8 hours
Currently on 4 hours with normal usage, it's heading for a ridiculous screen on time.

6 hours and 2 minutes with 41% used.
Crazy

Not that I've noticed.. its just the one from the play store. I think it's 2. Could be wrong, certainly more efficient than anything else I've tried.
I'm just happy I've managed to get my phone to be dropping 0% overnight, that's how it should be.
My 8 pro used to take about 4-8% overnight

Gonna try out Lawnchair launcher and see if it helps my phone too
Most recently I now have 8 hours SOT with 12% battery left. Feels good gonna try to empty the battery to 1-2% and report back the SOT here once again.

I got 2 % drain overnight 8 hours, which is ok for me with everything I got installed (airplane mode).
I wonder whether I will try lawnchair too, but I am using Nova for years

Comparing the two I prefer lawnchair, nova is a little too flicky for my liking, I prefer smooth transitions and fluidity rather than overly quick and flicky, you'll know what I mean when you install it 2% is still 2-6% better than the 8 pro..

Tbh that's still great time you're making.

It's nuts I'm on 7+ hours with 52% left.
Haven't been doing anything special, just using my phone.

Try disabling Google play Services when not needed. It has a bunch of power sucking dependencies. I disable more Google system apps than that on my N10+, but disabling play services may be enough to tone it down especially at night.
Use manual brightness control and keep below 50%.
Social media apps should never be installed for a variety of reasons including excessive battery consumption... just saying.

I agree buddy, but I'm not sure I need to disable anything else.... At this rate I'll have 14 hours SOT..
Have a look at the second post for my idea of keeping the battery down
But then again, could always have more...
So when you disable Google play services. What method are you using?

Just literally disable it?

Agreed, it sounds optimized to me! Hell yeah.
Most Android phones need to be optimized to get best performance... just the way it is.
I go to settings>apps, search for play, then disable/enable it there. I use it 2-3 [email protected] day, sometimes less.
If the disable option is grayed out, go to security and disable Find my Device as a system Administrator.
So many big sister Gookill system apps I hate...

Just done it but getting a lot of dings every time I unlock, little annoying tbh. I'm just wondering is the call to open services actually using battery ? I dunno. Perhaps if there wasn't a load of notifications..
I'll leave it for this cycle and maybe see how it compares next time, I'm not out over the weekend so have a good location to get fault results.

On my phone it can suck up to 1+%@hr with screen on... so it adds up. No reasoning with it.
You can kill those very annoying notifications; Gmaps, Gmail, do it; disable notifications. There may be more depending on your configuration.
Leave the warning running and when you disable notifications in the right app... it will stop. Instant gratification
