Screen Brightness kills battery more than you'd think

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.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

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.

Note 5 bad battery life gsam?

Hey guys , i am using this phone for the last one week and so far i am not impressed with its battery life.its almost similar to my xperia z1.
I lost over 24% battery in the past 2 hours just listening to music and surfing a bit.
Please have a look at my gsam screenshot and tell me if something is wrong.
Any help will be really appreciated.
Thank you.

Friend, take sshot from you apps usage and screen. Add sshot from stock battery manager too.

Thanks for your interest in my post.
I have attached the necessary screenshots.
I was having 3-3.5 hours of sot with my 2 years old xperia z1 and almost same with my note5 .
Not happy at all.
Today i left my phone at 41% went to lunch and returned after 90 mins and found battery left is 30% doing absolutely nothing.
Just taking the sshots and posting it here used 4% battery!!!!
Is something wrong?

11pm to 7pm off charge....looks fine to me!
I come off charge at 6am and it generally lasts to 8/9pm without a mid day charge.
Your screen is a big hog. Is brightness set too high constantly?
I don't play games but you clearly do - clash of clans....again another drain.
Big screen = big battery usage!
I've resorted to plugging mine in while I'm sat at my desk for a few mins here and there.
MM is poor though. The deep sleep / doze seems to work randomly.

Yeah i get your point
Brightness is about40% and i do play coc frequently
But my concern is suddenbattery drain. 11 % drain during lunch doing nothing and now 3% drain just opening xda and replying to your comment
Is that normal?
Also screen awake is almost 2 hours doesnt seem like doze is working

Check any apps you've recently installed....or start in safe mode and see if the problem continues.
Clear cache....
I've set up a greenify process - when I tap the home key on the home screen it puts it into deep sleep. I don't think MM doze works very reliably. Also my screen is at about 20%. Can easily whack it up when you go outside temporarily.

I have used 2 full days with just whatsapp and stock apps installed still the problem persists.
Please look at the sshot ,2 hr 14 min sot is absolutely ridiculous

Try the following:
- Uninstall Facebook
- Amplify
- Greenify
Has helped my Note-5 battery life greatly.

An App to control how often your wakelock & alarms fire off - https://play.google.com/store/apps/details?id=com.ryansteckler.nlpunbounce
Also, worthwhile alternative = Servicely (need to be rooted) - https://play.google.com/store/apps/details?id=com.franco.servicely
Try de-bloat script too by Battlehero.

Its funny how you and i used to own a z1 lol what a coincident. Anyways i think i commented about your battery life before. Regarding to the amplify im mot sure if op has root. I suggest you not to root if you want to exchange it saying its a defective battery.if not then go for it root it and see if it will change your battery stats. Pretty normal things to do is factory reset , boot in safe mode, maybe reflash firmware through odin and check any mysterious apps draining battery. Also maybe try greenify non root way for afressive doze. It shortens the time needed before going into doze mode. Im currently testing it right now.

Very disappointed in OP3t battery life. Not sure what to do.

I'm coming from a OnePlus One. Unfortunately, I can't find reliable BLP571 replacement batteries in the U.S., so I purchased a new OP3t.
On the OPO, I have been running custom MM and N-based ROMs. When the OPO (currently running Nougat 7.1.1 on TugaPower 2.1) is sitting around doing nothing, I typically see my idle battery current drain at around 9 uA to 14 uA and Wakelocks around 10%. Of course, when I turn the screen on, these jump up.
On the OP3t, I have tried running both OOS 3.5.4 and the new TugaPower 4.0 (which is based on Nougat 7.1.1). When the OP3t is supposedly doing nothing, I saw an idle current of around 85 mA on OOS 3.5.4, and around 35 mA on TugaPower. I didn't check the Wakelocks on OOS 3.5.4, but the Wakelocks on TugaPower are around 93% awake time (!!!!).
When I wake up in the morning, the OP3t is down to around 75% battery. For reference, my OPO used to be around 98% overnight when the battery was new. Even now, my ancient OPO with a nearly useless battery is around 85% for the same overnight time period.
What can I do?

3.5.4 actually has drain issues, try 3.5.3

Even after the annoying wake-locks and the random battery drain that just happens because why not... I still manage to get 5-6 hours of SOT, I have managed to push it till around 9 hours if I keep the Bluetooth and data off; with Greenify and using the aggressive doze it has helped but I don't get any notifications until I turn my screen back on.. Which is fine with me, as I get texts and calls. It's much better than the nexus 6 and the galaxy s4 which would struggle to even get 4 hours of on screen time. There are plenty of people raising issues about battery life on the OnePlus3T even though its probably much than your last device. XDA also has plenty of threads already created talking about the same subject.
Edit - I'm on the latest nougat update 4.0.1

the 3T or OOS doesnt have any drain or bad battery issues.
the problem is user/user-app based.
sort out the app which is causing the problem.

I just made a post to a similar thread. It seems the battery issue is hit or miss. At any rate, please check my post here: https://forum.xda-developers.com/showpost.php?p=70581453&postcount=9
Let me know if this helps you out. Look forward to feedback.

Greenify + ForceDoze = problem solved. I see 1% drained per hour at the very worst.

You stole my thunder.
Just kidding, but you're absolutely correct. I'm waiting to get my OP3T and then I will write a tutorial for users to help them out with the battery. Those 2 apps will be in my tut along with a few others that are helpful!

Weird, usually my phone, while idle of course, drains by 1% every 2 and a half to 3 hours. During use while im not playing games or anything im using pixel filter. Most time ive gotten is 9 hours 32 mins screen time. Im on 4.0.1 not rooted. Just uninstall apps u dont really need like amazon, youtube, facebook, tumblr and so on and use Firefox web browser. Firefox has background play for YouTube or any other audio source so you can stream music on Spotify soundcloud or whatever you want. I basically rely on Firefox for all internet things as if my phone were a PC. Saves time and battery because with 6gb ram my browser never slows down or reloads. Firefox is also really nice in the background consuming only 10mah every hour when not active or streaming audio. Cutting down ur app count will allow your device to doze longer, fetch less data and it certainly drains far less. Also if you're into this sort of thing, boot times are much quicker too.
Edit: sorry for the unedited massive paragraph here.
Another Edit: Make sure in case you want to use battery saver mode while streaming music to toggle Firefox to have unrestricted data usage in the data saver menu.

Check the link in my signature. My drain wasn't quite as bad but might help you figure it out. Good luck!

Thanks, guys! Greenify + ForceDoze seems to be helping a LOT! I'll need to let it run a few days to see the the real-world numbers.
I am having a problem adding apps to the ForceDoze Whitelist, though. Is that a known issue?

I've found that the whitelist appears blank until you add or remove an app, then the whole list will appear.

For me at times something appears to kick in in the background causing the CPU to spike and the phone to heat up. I can't figure out what it is though. When this isn't happening the battery drain is virtually zero and the phone flatlines overnight ,when it kicks in,the battery loses about 10% an hour on idle. I think there might be faulty drivers or something in the ROM causing this?! It's not apps as it happens to me on a completely debloated ROM with no apps. This is on Lineage and OOS. I've never seen this before on the phones I've had.

OOS 4.01 - I am experiencing exactly what you describe at 12%/hr and I have done literally all of the suggestions here. I have greenify, force doze, turned off location, disabled swift, did a factory reset and installed only 1 or 2 apps- and still I can watch battery drain with:
4 hours off charger and down to 44% with:
Kernel (android OS) 42.5%
Android System 33.7%
Google Play services 2.4%
Blah...Blah... (much smaller %'s)
What the heck could be causing this kind of drain? It seems to flatline when not in use for a while...
thoughts? Love the phone., but it is not usable like this....

4.0.1....No battery saving apps..

Hello,
I usually use Greenify Paid Version + Amplify Paid Version but only in 6.X roms in 7.X Xposed isn´t released yet....
Do you recommend use Greenify + ForceDoze (I never heard about this app) even without Xposed?
Thanks in advance.

I am still struggling with battery performance on my new OP3t.
I am running TugaPower N10 (LineageOS 7.1.1) + Better Battery Stats + Battery Monitor Widget + ForceDoze + Greenify.
While my wakelocks seem to be pretty short now, my lowest average current drain is 35 mA. For reference, my old OnePlus One had a lowest average current drain of 7 mA, or about 5x more on the OP3t.
My battery meter reflects the higher drain.
I have the same apps installed, maybe even some less.
Looking for more assistance ...

I'm on 4.0.3 OOS and using Franco kernel, 2% drain during all night, 5 hours of screen on time and still 56% battery, check what is wrong with your apps, or move from Lineage to OOS, is simply better.
EDIT: I'm not using any app like ForceDoze or Greenify

I'm not dissapointed.

Help please ;_;

Is this normal for a note 8? Settings = fhd+ no power saving mode, aod and edge lighting off. I know i m getting way low than i should get , I saw people getting atleast 4 + hours of screen on time everywhere

lowering quality and turning off aod/edge lightning will only save you a few minutes, you may as well have them on enjoy the features.
The SoT is user dependant, everyone uses there phone for different things and in different ways.
Also your phone has been on for over 20 hours, im sure you would get the same SoT as the rest if your phone was not sitting (screen off) running apps in the background for so long.
Having said that spotify is one of the things you have used in that 20 hours and judging by the %4 it used i'd say you were streaming a fair bit, that obviously does not add to your SoT but your still draining the battery. if you use your phone mostly idle while streaming music why does SoT matter?
No one can "help" you here i don't think, it is your usage habbits, this is what you get im afraid and from what i can see its not bad at all
my only tip would be if you dont use your phone turn it off instead of letting stuff like facebook eat away at your battery all day for when you actually do want to use it for Netflix or whatever :good:
Edit: Also your only at %25 still can get a couple hour SoT out of that :silly:

That's normal, that's how you receive instant updates from emails WhatsApp etc Facebook is an idle killer. You can either put the apps to sleep so there not active while idle or turn the phone off all together when you don't need it. Like I said I don't think there's anything wrong with your phone it's normal not for me but it's normal for you.

Samsung has one built in.
Go to Settings > Device Maintenance > Battery
click 'Save Power' that will put your apps to sleep.
Also you can scroll to the bottom of that page and press 'Always Sleeping Apps'
and you can add what apps you want to that list and they will never run in the background while the phone is asleep.
Alternatively you could use an app like Greenify.

You can try "greenify" at playstore, it is free, and a donation pkg that further enhaces its features

P20 pro battery issues

Hi
Got my p20 pro a few days ago, love the phone but have a few issues, mainly battery.
After seeing slot of comments saying how people are easily getting 6/7 even 8 or 9 hours sot I'm struggling to get to 5. I have display on auto, removed uneeded apps, have darkened colour selected for menus etc yet I can't get through a day of use (Twitter, email, internet and some YouTube videos) I do have Spotify on in the background slot, but looking at the usage settings the highest battery use for that has been around 241 ma, so not a great deal
Is there anything obvious I'm missing?
A second issue is that when using pinch to zoom in you tube in landscape mode I get a line between the screen and the notch which looks like a weird display gap and is really annoying, anyone else get that?
Lastly...in camera mode I've watched a ton of phone reviews and night mode is a swipe able option along the bottom, next to aperture mode etc...however I don't have this, I have to go into more then night mode, anyone know why that is? ( I'm in the UK if that makes any difference)
Thanks for any help you can give
Ross

Same here, Im not impressed with the battery.

Same here. Its not a deal breaker though over night
I lose 2% on idle with aeroplane mode on and then shortly using 2% drops off.
We seem to forget that this is the initial release of the firmware - I am sure huawei will optimise it further to improve battery

My phone nearly always gets charged overnight, the fact that this is now easily getting me through the day with zero scares is good for me, I'm not trying to eek 2 days out of it, if Huawei somehow get that then all well and good, but for now I'm happy knowing it's unlikely to die on me if I leave the house at 100%

I had the same issue, but seem to have stabilised it.
Try the following :
Stick to one resolution rather than smart.
Disabled adaptive eye.
Keep the notch on
Managed all apps manually (setting only my key apps to auto and run in background)
I also deleted the cache on all apps and the system via boot menu because I think migration caused some of the issues.

I'm sure mines got something going on in the back ground, fully charged to 100% left in standby while driving to work, arrive (30 mind later with the phone not used) and it's gone down 3%.
Tried the settings above and have manual control over all the apps, I kill off apps after I use them and it's still draining worse than any phone I've had for the last few years.

Yeah, the phone menus are a step backwards from the mate 10 pro. Dunno why they've done it this way

I get between 8 and 9 SOT a day, Wifi most of the day, 3 hours netflix on 4g with BT headphones, instagram, whatsapp, web browsing, streaming deezer music on BT headphones, texts, some calls. No snapchat or games though and facebook is not logged in.
Haven't tested standby drain yet but maybe it's standby that's killing your battery?
This is in one day though and is excessive use as I have two Instagram accounts and lots of work emails as well. I also don't have a pc at home so use phone for browsing.

How is your settings within the battery category? Do you manage the apps to etc run manually or what do you have in the settings that gets you so much of SOT?

So after some days of testing and trying out some battery monitor apps, the max SOT that I get is 5 hours and 45 minutes.
GSam reports that Android System and Kernel (Android OS) use more than 30% of the battery combined. Is that normal? I'll attach some screenshots.
What I also find interesting is that the AccuBattery app shows that the estimated capacity of my battery being at 3500mAh out off the 4,000mAh design capacity and battery health is at 88%.

I'm sorry but how do you achieve this? I barely get 5 hours SOT with WI-FI on, instagram, messenger, facebook etc. Also my apps are running on AUTO APp launch.

Have you figured out what is causing the problems? I'm having pretty similar issues.

Unfortunately I haven't had any luck either. I've deactivated almost everything that could be using up the battery and I still don't get more than 6-7 hours of SOT... I've had the phone for two months now, battery life didn't really get better as some people mention. I carry a powerbank with me cause when I'm out and taking photos it doesn't even make it through half the day...

Did you guys deactivate the option mobile data while connected with wifi? That drains a lot of battery while connected with wifi and is activated out of the box for no reason. What also drains battery are the two options under location settings to search for wifi networks all the time.
When I was on emui I set all apps to manual and only activated active in background and auto start for apps that really need it and I want to get notifications from, like WhatsApp and telegram.
Under mobile data settings I also deactivated background data for those apps and boom, easily 10+ hrs SOT when on WiFi or 7-8 hrs on mobile data.
I'm running force Doze app as well but that might only help with standby drain.
Oh and get rid of Facebook, messenger and snapchat if you want good battery. They are known for huge drain and there are good or even better alternatives like Friendly e.g.

That does not sound too bad...At least you're getting 6-7 hours of SOT. I'm getting like 4H MAX lately. And that is mostly internal usage! with low brightness.

Thanks for that! I've just disabled "Mobile data always on" and we'll see how much difference does it make. I also might give Friendly a shot.
Also, if I disable background data/app launch for Facebook, that will surely prevent facebook to sync constantly, right? I don't need constant notifications from facebook, only from messenger.
Also I noticed I went to sleep with 100%, after 7 hours I woke up with 92% left. That is with Always ON display. Is this normal standby drain? I'm also thinking about disabling always on display as it does not show notifications correctly anyway.

Yes that should prevent notifications from Facebook.
Hm when I charge it to 100% I usually still have 100% when I wake up 7hrs later. That doesn't mean I have no drain but I think the phone stays at 100% fairly long and seems to drain faster on low battery percentage (similar to iPhone afaik). When I charge to 90% for example I wake up with 87% or so. That's more realistic I think. Wifi on, everything else off, no AOD.

Not too many actually. Could probably deactivate some more but seems fine as it is.
My system is German but it must be somewhere in wireless and network - mobile network - advanced.
