Hello, my phones battery life is I'd say average.
I get up in the morning after its been charging all night, and after its been unplugged for maybe a half hour, with a few texts and a minute of browsing done, the battery has gone down 5%.
Battery usage shows that display is taking up 89% of the usage!
Why is this? Is it normal? If not, how can I fix this?
Display will use most anyway. Get a darker home screen, either use low brightness or auto-brightness. not much else you can do.
Let me guess you're using CyanogenMod?
I've seen reports of my same problem, and those that had it found a solution by wiping the battery statistics, letting it die, then charging it to 100%
But no, my nexus isn't even rooted.
Strange. Before I was rooted my display would always be 1st or 2nd, along with android OS
After I rooted using Cyan, it was always 1st taking up more than 60%
Then I switched ROMS now its always 3rd or even 4th
Sorry dude.. try wiping batty stats and changing your brightness.. are you using live wallpaper? what about screen timeout.

has anyone thought that the battery usage stats has to equal 100% so if the operating system on CM is running lighter (usin the cpu less or in a more efficient way) then the display would be taking more % of battery usage making people think there is something wrong when probably there is nothing wrong. maybe the desire ports (modaco ro king) use more cpu and thats why the display is 3rd or 2nd.

This is perfectly normal. Displays are power hungry relative to the rest of the phones components.
Google maybe shouldn't have included the battery usage page as it just leads to confusion. When you use up 5% of your battery's power and then check the stats and see that the display is listed at 89% it means that of the 5% used, 89% went to powering the display. It does not mean that the screen has used 89% of your total battery at that point.
Leave the phone alone for a while and you'll see that the display percentage will go down while things such as Cell standby will go up.

Nobody thinks of that
-------------------------
I am on more than 9h of use still 50% battery left!
- Autobrightness on
- No taskkiller!!
- Wifi on all the time
...and using it today a lot, mails, web, twitter,....-> made a logcat this morning and eliminated my battery drainers
Agh! I want better battery life! I feel like it's dying much too quickly....
buy a bigger battery
or stop fiddling with it so much, lol
turn the brightness down. turn the sync off. turn off background data. don't use bluetooth or wifi. turn off your location.
don't use live wallpaper, use a darker screen that doesn't move.
i know on my winmo phone if i turned on bluetooth, battery would just get sucked out. i couldn't charge
it as fast as bt used it up. and that was with a fastcharge reg edit.
I believe you just got your phone, right?
It's cause you're playing with it so much.
I dont feel like I am though. I am using it probably just as much as I use any other phone I've had.
Maybe the battery just needs to be broken in.

Nobody ever thinks of that unfortunately. I would think display using the most would mean you're using a pretty efficient device.
Yup. That if you want to keep your battery as long as it can get. Else, if you want to enjoy your phone, buy a spare battery along with the desktop charger and you will survive a day...

I switched to enoms which gave me a little better battery life. Also downloading juice defender made a noticable difference, I use the free version at the default settings. I also switched email to hourly which is adaquate for me. I dont run bluetooth unless I am using it, same with wifi, which is what I do with all my phones. I dont otherwise change my usage, dim the screen etc. Overall I make it through the day with typically about 35% left. Based on what I see here my usage would probably fall into the light to moderate range. To be honest I havent had a smartphone recently that did much better. I pretty much figure I gotta plug in every night in the modern phone world.

As others have mentioned, the display uses the same amount of power no matter what rom you are using. So if display is 3rd or 4th, you have an absolutely crappy rom that is using battery probably 10x as fast (compared to same usage where display is 90% of the battery).
In simple terms, the higher % your battery is using, the more efficient your phone is being.*
*compared to same usage at same brightness running different software.
An addendum to juice defender. I had it on the default setting but changed schedule so that it lit up apn for 3 minutes out of fifteen instead of one, my email wasnt consitently downloading at one minute.
I noticed that you have gone to 5.0.6, how is your batt life now? I stayed away from it just because of the overrwhelming number of bad battery life posts on it and was surprised you went that way.
I didn't use the note much, but it needs to charge each day. This is bad than tablet. Any software to save battery? I tried 'air plane mode' sofeware, but it also turns off phone after sleep.

What apps and widgets are you running? Have you gone through 2 or 3 full discharge/recharge cycles? There are apps out there that can detect if any app is consuming your battery but you will have to search the forums as I don't know of any first hand.
Also, which ROM are you using? When I was using Rocket Rom v22 with AbyssKernel 4.1, my Note would last more than a day on the same charge even with moderate use. Give that a try as it also really boosts performance.
I'm currently on Team Rocket Rom (ICS based) v5 but have not used it extensively to comment on battery yet. So far with 3 activesync email accounts (all push), some widgets running (weather, clock, etc.) and the Note sitting idle consume about 2-3% battery per hour. Will monitor this.
most smartphones ned to be charged every day, what battery life are you expecting to get ?
battery depends on the usage and applications you installed on the phone.
have you tried rooting already? usually custom roms have the best alternatives of extending your phone's battery and giving it an optimal performance.
Try to stop some bloatwares that your phone's loading up everytime it starts up(from rebooting)

I am using la2 rom. Here i attached an picture.
Geez... i personally feel that one day charge is reasonable especially with the juice required to drive the big display.
Anyway, Juice Defender premium is one app that has helped me, and may help you too.
Since you got Activesync, with the premium version of JD, you can customize app to be excluded from 'power saving', so that the inbox is up to date.
+1 for juicedefender.
Other tips that may not be obvious to first-time smartphone owners are:
1. Set your screen brightness to auto. You don't need the brightness cranked right up all the time.
2. Disable bluetooth and GPS if you're not using them. Juicedefender will do a pretty good job of managing your other radios.
3. If you've got email syncing set up on your phone, set it to check as rarely as you can put up with. Push email uses a LOT of battery life, and even a scheduled check can blaze through your battery if it's happening often enough.
4. If you've put on a custom ROM your phone may be reporting inaccurate battery stats. Give it a full charge, boot into clockwork recovery and wipe your battery stats. You'll find a few days after that your phone will start reporting more accurately.
Good luck, and if any of this was unclear feel free to ask further questions.

Try a later ROM to see if the same issue exists. I think you should instal rocket rom v22 - you'll be happy with performance and battery life based on your usage.
try to calibrate your battery as well... there are many apps out there that offers better battery calibration or you can do a manual calibration as well.
Give it some time and upgrade your ROM
I am getting great battery life. It runs for full day (24 hrs) with 30% of battery usage. though in a day i dont use it much, just 5 to 10 calls of around half an hour to 40 minutes.. data and gps always on.. screen brightness on auto...
My note running the OEM battery last me about 6 hrs.
Averages about 45mins talk time/day
About 50 SMS/day
Screen brightness set to 100
Checks email every 5 mins
Using a live wallpaper
Refreshes the daily weather using Accuweather every hr
Bluetooth always turned on
Battery Widget
Fancy Widget
ESPN scoreboard ticker widget refreshes
Twitter running all day
Facebook Widget syncing all day
and more...

^ This. Or better yet, just always set your brightness to the lowest brightness setting, 50% afaik. And use black/dark wallpapers and always turn on night mode (if applicable, especially when using your browser)
If in case you need to adjust the brightness, you don't have to go through the jungle of settings, just click notification bar and slide horizontally to change to your preferred brightness.
Jd is hit n miss will actually helping out. If your phone sleeps a lot jd is nice at keeping cell or wifi off if your like me and on it every 10 minutes then toggling data and other things can consume more juice. .... I have tried with and without on my tablets and phones and see no big difference depending on use.
Sent from my Ice Creamy Galaxy NOTE
I was pretty happy with my battery until two days ago. I use my note very little, for e-mail checking (which I pull manually) a few times a day, and to make two or three phone calls per day. I also text my kids occasionally. GPS and Bluetooth are off most of the time. Battery used to last me about two and a half days under these conditions, which seemed reasonable to me. All of a sudden, two days ago, I charged my battery, and after a full charge it drained 60% overnight. Thought that it was a fluke, so rebooted my phone, fully charged again, and the same thing (over half of the juice gone overnight) happened again. Battery stats tell me that Android OS were 100% responsible for overnight drainage. Any clues? I am on stock ROM, by the way.
Thank you.

Get a good app to check what is using the battery or keeping the phone awake. This last is the most likely.
Baddass Battery Monitor is my recommendation.
Not a single phone call, only used about 10 mins. after 21 hours only 11% left. Install Jd with 'balanced' option.

Badass, got to love that name....
Ok, I used the Badass monitor to see what's going on. Once again, no phone usage, quick overnight battery drainage. Android OS 100% responsible, and the main power sucker is the Kernel (96%). Why is this happening? And, is there a remedy? I have changed nothing that would trigger this! My Note is still within the return window, so if there is anything wrong with it, I will return it.
Thanks again.

Badass Monitor is very useful, my note was drained by Dolphin Browser, it used 38% of battery. Seems like for this browser, if I only press home key to exit, It will keep running?
I think the reason the battery drain fast is we press 'home' key to return to main menu, that will keep a lot of apps run in the background.
So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

last night with 10 hours sleep time. with wifi connected sync was activated for 3 mails. i just lost 2% and i didnt do anything special like you did. no greenify no root nothing i couldnt even install wakelock detector cuz its broken on kitkat without root.
. i just disabled some useless stuff like samsung store etc.. everything else is working. and on my car i generally listen music over bluetooth
Lux could help

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL
Greeny can also help but may need root
I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.
I loose only 2% for 7h of standby last night.
We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?
I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why
Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.
Delete it pls.

Ok as you know the phones with the Xynos chip has pretty rubbish battery life but I've found a temp fix until samsung hopefully fix the issue. You won't notice any slow down or compromise the use of your phone.
All it is is set your phone to mid battery save and keep all the settings on but limit the cpu.
You can still play all the latest games without a stutter, you can't tell the cpu is being throttled.
Try it for a day see what you think, I also have Always on Display turned off for extra savings.
Interesting, will give it a try today, been averaging 3h40m for 50% battery usage (Not run it down to 0% yet) so will be able to see if it improves much
Says it has added over 4 hours to my battery life estimate
Thanks for the suggestion, will be testing soon.
My issue with my Exynos S9 is the standby. It's not completely terrible unless I'm in a crowded bar or an area with zero reception, but I can never get it to be good. Even with everything disabled (location, sync, AOD, lots of apps, etc) I can't get it under 1.5% drain per hour. With it all on I can easily hit 5% drain per hour, sometimes more, which is weird, cause the actual SOT doesn't take much more than this; 8-10% when stationary on WiFi, 12-15% when moving on mobile data.
Seriously the SOT on this thing is great (FHD+, haven't tried QHD+ yet). I reckon I could easily hit 7 hours, possibly getting up to 10 if I'm just browsing/watching shows in bed all day. But dear god the standby is driving me nuts.

Standby drain will be higher if your phone is in a pocket, doze only kicks in when the phone is sitting completely still so no sensors are active like gyro etc (unless that has changed in Oreo)
So standby overnight should be significantly better than when you're out and about with it

Yeah makes sense, but it still drains 1% per hour overnight, whereas other phones I've used only drain about 0.5%.

That's also the consensus I've been seeing elsewhere.
No idea how to fix. Seems that only my HTC 10, which has horrible SOT (drains about 25% per hour) can get standby this good, and yet it's still worse than most other people's.
2.5% per hour on average during the day with location and sync (but not AOD) on is actually good for my S9, yet it's still poor compared to everyone else's it seems. Today, with location and sync off, I'm averaging 1.5% standby drain per hour. AccuBattery staying 86% deep sleep, whereas it's closer to 65% when location/sync are on.
idunnolol, maybe I have poor signal? I'm usually on 2-3 bars. Or maybe an app I use is sucking power? ¯\(°_o)/¯

2.5% per hour on average during the day with location and sync (but not AOD) on is actually good for my S9, yet it's still poor compared to everyone else's it seems. Today, with location and sync off, I'm averaging 1.5% standby drain per hour. AccuBattery staying 86% deep sleep, whereas it's closer to 65% when location/sync are on.
idunnolol, maybe I have poor signal? I'm usually on 2-3 bars. Or maybe an app I use is sucking power? ¯\(°_o)/¯

There's a few people with this drain problem and up to now we're starting to think it might be related to the modem, as with the SIM removed the extra drain is gone
It also looks like it might be related to which region/CSC firmware you have running, I am running the United Kingdom O2U firmware and do not see this extra drain
But this is all theory / guesses right now, nothing solid

Yeah makes sense. I'm in Australia, not sure how to find my firmware version. I'm guessing it's in Software Information? But there are a lot of numbers.
I find the Exynos modems seem a little worse than the Snapdragon ones where I live, though it could just be the specific places where I work and travel.

I think I isolated the issue by disabling extra packages last night, but I don't know which of them. Will see after tonight for sure.
Can you please enable aod (even though it will be turned off between 12-7AM) and the facebook packages for a night? It will help us narrow down the issues.
I used your settings - fb -aod and still had drain.
Will flash the O2 firmware if the drain continues overnight.

Yea sure, so enable AOD but set it to turn itself off between 12am-7am?
Enable FB packages
I`ll set that all up tonight, then charge to 100% before bed, see where it is in the morning

Thanks. Would've done it myself, but I want to know if disabling some of the services isolates the issue.
Maybe it's AOD+FB or other issue (that I might've fixed by mistake). Took this post as a reference: https://forum.xda-developers.com/showpost.php?p=76543514&postcount=49
Disabled some of the packages until I got bored + the ones you disabled.

I've always disabled both tbh, only left FB package manager or whatever it is needed for the GearVR on my S7 for a while when I was using the Gear, but got bored of that and disabled them all, AOD gets disabled straight away, phone definitely cannot be as deep sleeping if that is active, and the screen is using power the whole time too, albeit only the pixels that are lit, but still more than having it 100% off
I tested with AOD on and off on my S7 and got huge overnight drain with it enabled vs off, same throughout the day, the phone couldn't enter Doze fully iirc

I didn't think AOD will drain battery since it's turned off in that interval? I had a OK drain after factory reset with AOD on. So idk what the hell is happening.

I meant when I left it enabled and on the display the whole time, different phone and different version of Android though
Maybe after the factory reset, because the system apps are back to their original versions, drain is OK, then when they update back to the newest the bug is brought back? Or are you updating everything 100% before testing?
Samsung system apps get updated from the Samsung app store too so you'd need to sign into a Samsung account to update those iirc

Everything was up to date before testing. So I have no idea what is causing the drain to lag.

I think I'm on ARD4? That's the last 4 numbers of Bootloader and PDA Version. CSC is ARCA and Baseband is ARD6.
I've already got FB disabled, amongst pretty much anything unnecessary. Although I do use FB Messenger as everyone where I live uses it.

ARD4 is the firmware before latest, apparently the latest BRE5 fixes some drain bugs and other things

Ah well, we'll see tomorrow if FB / AOD causes it for me, if not then at least you've disabled whatever was causing it
Export your package disabler list and save on a PC for future in case you reset again

I have heard that. Will defs be testing, cheers.
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
