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.

. 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.

[Q] Battery drain, who's the guilty?

Hi guys,
I've a XT1068, does anyone have the same problems with the battery?
I was not using my phone where the battery started to drop like that. I charge it, then unplug it and then went to bed.
Yes, I've wifi, bluetooth and 2 SIMs with one of them with data always on.

Same for me. When I bought the phone I immediatelly upgraded to 5.0.2. After upgrading, I did a factory reset through Recovery. Android OS and Android System eat up most of the battery, whereas in normal cases it should be screen and standby (and perhaps some fewquently used app).

Looking at that first screenshot of the battery chart it looks like you have an alarm or wakelock keeping your phone awake when it should be sleeping. Take a look at my Moto G 2014 battery guide

Well that guide is great as a general recommendation. However, what we have here looks like a bug. Android OS and Android System should NEVER take more battery than standby and screen.

You are right. And I see that in my xt1032 that still runs on KitKat these wakelocks do not exist. Could this have to do with data wiping? I factory reset the phone from recovery AFTER the 5.0.2 OTA update. AFAIK it fully wipes data and cache.

It does. Install BetterBatteryStats from here and run it for a while. It'll give you details on every wakelock and alarm on the device and how much battery it is using. Then you can use amplify in the tutorial I linked to earlier to configure the wakelocks so they are not consuming as much battery.

Thanks a lot Duck86, but I think that for a brand new phone I should not need to do all these things to get decent battery life. As I said my old xt1032 on kitkat was is to handle two days of significant usage and most of all, if you did not use it the battery did not drain. By the end of the day, battery usage was topped by standby, screen and perhaps an app with frequent use. On top of that, 5.0.2 looks generally unstable compared to the utterly robust 4.4.4 that runs on my xt1032. I get noise and lag in call sounds for example, issues that were not even imaginable on xt1032/kitkat.
So I think I will try to fall back on kitkat. The problem is that I do not know which stock ROM I should install.
My Baseband version is:
MSM8626BP_1032.3105.93.00R EMEA_DSDS_CUST
My kernel version is:
3.4.42-g48d3b85
My system version is
22.21.28.titan_retaildsds.retaildsdsall.en.03 reteu
Build number
LXB22.46-28
Any clues?

It's probably gsam battery monitor that is doing all the wakelocks to gather data.

Nothing special, depends on what you were doing. To have a clearer view: Load your battery until it's full and let the phone rest for one or two hours. Make some screens than. You can see what kind of wakelocks disturb the sleep mode of the device.

"Who is the guilty?" Motorola?..
Guys you know about the bug with the gps? When you turn on and off the GPS on the stock rom and the GPS remain on and kills your battery until you restart the phone? Took me about 2 weeks to figure out.

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.

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.

Experiments searching for better battery life

Please reply with your own real experiences.
Q. Does rooted Greenify really improve battery life?
I use it, but I can't say it makes a huge difference.
Q. Does Package Disabler Pro really improve battery life?
I use it, but my co-worker doesn't, and his Note 5 lasts basically as long as mine.
Experiment:
Maybe what would be the most useful is using Tasker to really deal with battery life. I'm thinking about shutting off wifi and data when not needed, etc.
Has anyone tested something like this?
Thanks!:good:

Hey gaston. So I haven't rooted my note 5 just yet but I spent a year and a half with my opo trying all the permutations you mention.
Rooted greenify I feel works a lot like doze on marshmallow. If you are gaming you tubing etc constantly you won't really feel a difference.
Tasker is awesome and you will notice a difference in battery life to an extent but it goes way way beyond in terms of automation. If you end up using tasker profiles based on location and wifi you may just end up using more juice.
Package disabler using the profiles I have tried so far marginally improves battery life but nothing sizeable. I feel it makes the phone snappy by freeing some ram but that might just be a placebo.
Ergo I run the phone in full beast mode now and make use of the fast charge once in the evening for a half hour and that's good to get me through the day.

Hey gaston. So I haven't rooted my note 5 just yet but I spent a year and a half with my opo trying all the permutations you mention.

Thanks!
I appreciate your honest reply. Many people here in the forums seem to lie a lot about performance and battery life.
Maybe keeping the phone charged is the best and simple solution.

That being said you are rooted so go ahead and try the custom roms out there. That is the one sure fire way to see a difference in performance and battery life.

I've been using Greenify (unrooted), Package Disabler Pro, and dark themes to maximize my battery life. But I think Tasker does the most to help me conserve battery power.
When I am at work, Tasker turns off WiFi, Bluetooth, all sounds, and drops screen brightness to about 20%. I only turn on GPS when I am using an app that requires it. Tasker turns my brightness and volumes down when I am connected to WiFi at home.
I think these simple actions with Tasker help my battery life more than just about anything else. I average about 6.5 hours of SOT, and I still have 30%+ left on my battery when I get home.
But it all depends on how you use your phone. YouTube and video games consume more juice than TapaTalk and light Internet browsing.

Just try to uninstall or disable facebook app via settings, and feel the difference. I read on Internet that Facebook app known as battery eater. Just try it and give some response here. Hope that help.

It depends. Some people want the extreme battery savings and are willing to sacrifice a lot of performance on the phone, dim screen, no GPS, etc.
I prefer my phone to operate at its full potential all the time. I don't want to mess with settings if something came up and someone wanted to see a picture and I have to worry about setting brightnesses and whatnot.
For the most part, most of those apps are only getting a marginal amount of better battery. Maybe 20 or 30 minutes more charge over the day.
During work, I rarely use my phone because I'm actually working lol. Sometimes I use it for work but the quick charge takes care of whatever I lose during my lunch hour
I use GSAM the monitor was actually using the most battery in just address what's needed. The only feature that I usually do turn off and keep up for the most part is my Wi-Fi. In the areas I use my phone the most, my average download speeds over cellular are over a gigabit

greeify - yes, only if you know greenified app was a battery drainer.
package disabler - yes, only if you know those services were battery drainers.
I use betterbatterystats app to find out what is draining the battery.
biggest culprit for me was phone not going into Deep Sleep. If you can remedy deep sleep issue, your battery will last much longer. I currently get around 1 percent drain every 2 hours when my phone's screen is off. that's with wifi on all the time.
Best way for me was installing a custom rom. most custom roms will have battery issues fixed. I use dr ketan's rom. it's awesome.
Another way without rooting that I found out, is disable google services. google play services and all google services. if you do that, watch your battery last forever.
I forget which app, but you could make profiles so you could enable or disable all google services, and google play services. I mean, you don't download new apps all the time, right?
So only enable google play services when you want to download apps and turn it off for the rest of time.
and of course deal with bloatware.

I'm glad you asked, i've been using greenify amplify and powernap as of recently, and no it does not improve battery life automatically but it helps to keep your running services in check.
I've had couple of times that chrome was running in background, despite i closed it, means it drains battery when your screen is off, greenify prevents that from happening which result in battery improvement or more precisely, helps you manage the services right.
However to my surprise, calibrating the battery via batterycalibaration app or L Speed tweaks apk(both need root), it stabilized my battery after couple of cycles, i did a test charge the phone to 100 then using performance governor, i put Angry birds 2 till the battery reached 5% so i could see the SOT, before this step i had 2h 45m but AFTER calibration i had 4h 30m, that a LOT for performance non stop ab2 gaming.
It helps with regular uses as well, i also used repair battery to make sure that battery health is in check, hope all that helps

I've tried this several times and over the last 3 weeks and honestly have never notice any difference to battery life. The less features of the web version to me doesn't warrant this as a worthwhile change.

Re dr ketans rom assume this requires root? Does it take away features of the standard rom or is it closely linked to the OE Rom?

Interesting. I've never tried calibrating a battery.
Honestly, I feel fine with my Note 5. But I always imagine what I want from a ROM or device:
Better battery is always good
Fast performance is good

Hey..
I was interested when you mention using Tasker app, so I tried to use it.
When I was setting the app I try to set WiFi on when at home and set off when I'm not, does this need root? could you share the tutorial setup to me?
One more thing, I tried set GPS on when using the allowed app, I find this set must be rooted, If you could, would you share the tutorial setup too?
thanks

Seriously? Swipe down and toggle wifi and mobile data on/off!
Less than 2 seconds plus you can see your beautiful notification drawer if you using a theme you like!

yea, any rom install requires root. I thought about not rooting my note5 for a while. damn knox count that disables samsung pay + much harder to sell and lowers the resale value. HATE samsung for doing that. I mean, if I flash a stock rom, everything should be back to normal. ONLY company that makes the resale value of phone drop forever, if you root!
sorry, i digress.
dr ketan's rom is very clean and snappy. he only removed knox and carrier apps, and left everything stock. didn't take away any functions, but added "actually useful" features. insane amount of features without slowing down the phone. it feels like stock rom without the bloat and the usual "limited" feeling of stock. battery life is improved also. especially the deep sleep. what i noticed was that, when i was on stock, deep sleep was pretty good already, then I rooted and deep sleep was out of wack. I tried everything for the deep sleep to be better, but didn't work well. so i flashed dr ketan's rom, and deep sleep is now actually better than stock.

Yeah, there is a pretty steep learning curve when it comes to Tasker. On the bottom right hand corner in the Tasker app, click on the question-mark icon. From there you can click on "Guides" for user tips and tutorials. Click on "Userguide" for the manual.
GPS cannot be set without root, since Gingerbread OS I believe. I manually turn it on and off when I need it. I leave WiFi on during the time frame I am at work. Tasker turns it back on at quitting time. When I get home and connect to my home WiFi, Tasker sets my brightness, sound levels, etc.

Who Else's Battery Life Sucks On Android Pie?

I've had Android Pie for about 5 days and I have found that my battery life is dropping like a rock.
I don't ever have my brightness on more than like 20% and I have found I am losing about 10% battery life after using my phone about 20 minutes.
What the hell?

Here's a screenshot of some stats...

You use many jank drainers apps. This is not android issue or rom issue. Your phone is not debloated. Your deepsleep is bad too. Your cpu clearly no sleep correct. Debloat your phone from this jank drainer apps. Use adhell if no have root for debloat and freezing jank apps and service. If you have root change rom and kernel and beloat with titanium backup. The brightness is the last part who gives you the extra battery. If you dont clean your phone dont expect good batterylife. Note 8 is not a battery phone.

xda have so many tutorials how to debloat your phone correct. And how to boost up your battery. If you search you will find many of them.

Thanks.
I'm a novice. What can I do without rooting?

Disable applications, using a Package disabler app.

Its not even necessary to use a package disabler
The usage of nova launcher is not normal.
Did you do a clean install after the pie upgrade?

The battery life on my Note 8 is pretty good running on Pie. If I am not gaming on it, I can easily get 1 and 1/2 days use out of it.

How? Please show your settings!

I run it with no battery issues. It lasts me for the whole work day from 7 to 5 and later on to when I go to bed.
I do see you use battery management apps that do nothing but waste more battery. It's more reasonable to use the built in one in Device Care or close apps you don't use. Also use Dark Mode. Lowers Battery Consumption and easier for your eyes plus it looks good.
I run it at WQHD+ and AOD On. No Power Saving Enabled

the Android update sucks! youtube has no on screen brightness or volume control now and the video scrubbing (ff & rew) is gone plus no more saving the video. the zoom on the shutter button is gone now for the camera...

My battery life is wack on Pie, honestly. I've tried fresh installs and apps like wakelock blockers, and I can still barely last a school day. I honestly think it's my battery in terms of its health. Stock Pie seems unoptimised to me.
Though it is known the whole "calibration" stuff helps, e.g waiting 3 days for the system to sleep things, or going 100 - 0 - 100 to see if that might help. It did help me for a while.

Waiting for the system to sleep things for three days?

The April security update fixed my battery woes.
