this photo with my current I9100JPKJ2 2.3.5 + siyah last kernel
the battery dead just in 3 hours of heavy using , it was :
" 3G always on + twitter app always on + some camera "
and everything else was off and automatic brightness and disabled fast Dormancy
and that what happened , it dead in just 3 hours !
so please tell me what the same conditions with your experiment
how long it lasts ?
how many hours it gives me with this using ?
i was about using TurkbeyRom , but i asked first maybe there's better one
any ideas ?
CheckROM v4 is very good.. Even with default settings...

how much screen on time? i got about 6hours max
I'm guessing you have a metric ass load of apps running/syncing and draining your battery whilst your phone is awake. If I keep my screen on time to ~4 hours I can get 3+ days (approaching 4) of life out of a single charge: Wifi on most of the time, data off when in Wifi range, sync off, every thing that requires syncing I've set to 1 hour intervals. I weeded out battery draining apps some time ago using Better Battery Stats. Your phone is asleep when your screen is off however, so that's good. BBS might help you narrow down processes but these may not show up under Partial Wakelocks.
I am on an extremely tiny ROM however and the same can't be expected of a stock or modified Samsung ROM. Disabling fast dormancy can drain battery depending on if your provider supports fast dormancy or not.

Insanity 56 + it's stock kernel. It's based off CM7 (7.2RC0 I believe), but slimmed down to 47MB.

If you want to use Twitter and Facebook apps you'll have to accept that battery life is going to suffer a ton. Good battery life isn't a holy grail or unattainable by any means, it's all in the apps and settings.

yes i know
but as you see , must people already confused me
some says it normal , and some says something wrong !!
i know it's normal when we talk about heavy " hardcore " using
but i have some hope that i can find any solution gives me extra little hours
every hour needed really in my case !
It's not a great battery profile, but it could be explained easily by screen on time and lots of apps running in the background. I guess it's a matter of figuring out which app(s) are responsible and deciding which you can live without to at least make it through the day without being at the mercy of the nearest electrical outlet. I find I can easily make the battery suck on this phone; nature of the beast.
yup i know .. but i am very confused because people keep telling me something is wrong !
some people said they got 10 hours with heavy using like mine !
Not everyone's idea of heavy use is the same, no way battery will last 10 hours with screen almost alwasy on.
Maybe you should look into an extended or spare battery instead.

No, your battery graph is normal. Every Rom, every kernel will show this result with the usage you have, don't let people fool you otherwise.

No, impossible. You can only have around 10 hours of screen-on time while doing *nothing*, I've also accomplished that once:
While on other occasions it will look like this:
So all that BS that Rom X with kernel Y will magically improve your number of hours: no. Only thing that matters is: what's running in the background, what's being displayed on the screen (dark or light images) and if you're using lots of bandwidth.
Browsing the internet while displaying a light screen: max screen-on time of around 4 hours (so: battery will be dead in around 4 hours as well). Using the phone otherwise while displaying dark content: maybe 5 hours screen-on time or more.
All that "I have X hours of screen-on time with heavy usage!" where X>5 hours is complete B.S.
Thanx a lot , now it makes seance
now i am officially disappointed , lol
ok , what about new batteries that samsung made recently
i heard that there's some improved batteries last longer than the stock one
is it true ?
sorry for asking about that , recently i am here a lot to see what is new
is there a new improved " tested " batteries made recently last longer the stock ?

My X is greater than 5.
I'd think more about grabbing a bigger capacity battery or more batteries so you can swap over to a fully charged one when you need to.
I agree with eliminating unwanted battery drain but I don't agree with not using apps we want to use.
We have an awesome phone. Enjoy it. Use what apps you want as much as you want. So you have to take 2 minutes out of your day to swap a battery who cares. Better that than having to use it like an old Nokia.

You can get double capacity batteries if you don't mind losing the phone's slimness

If you have this necessity of being constantly online on Twitter, Facebook and whatnot you might want to consider another device such as a tablet or netbook? Can't expect to do everything on the phone and have good battery life. That said, try ing different governors made a good difference in my case.

What is the deal with this phone? The battery life is not very good at all. I came from a phone that had a 1150 battery and this one has 1600! I am getting almost identical battery life as my old phone. I am running a fully debloated rom at stock clocks with the display turned all the way down and can HARDLY make it through an 8 hour work day. I've narrowed it down to the screen.
I remember reading about amoled when it was first announced and they said it would consume significantly less power than any other display technology. I'm starting to second guess this.
Its either the screen or the dual core processor that's draining this decent sized battery so fast.

Amoled does. From what ive beem read ing super amoled plus.is alot better. The darker the better. Slcd is.a.good option for battery mizers though.
I voided my warranty and your mum.
Yes ive also read that the way super amoled plus works, is there is no backlight and individual pixels light up, so its better to have simple wallpapers with mostly black, would probably give you better battery life, as most of the screen will no be using any energy.
All android devices murder their batteries. It's nothing new get over it lol.
This device gets decent battery life considering it's the most powerful option out currently though.
The general masses do not understand how to set these phones up for optimal battery life. There are threads all over XDA on how to do this.
This phone for android is probably the best or near best in its class. I am impressed. Its better than my captivate was. I can get through 15 hour days with heavy use all the time with average of 4 hours screen time and i listen to a lot of music when the screen is off. This phone rocks i dont even see the need for a extended battery

I have no idea what you do with your phone or what . But I get more then enough battery with this phone, I do it all text talk surf web forums play and I make it home with enough battery to probably lend you some. Seriously we all know your not going to get iPhone battery life obviously the iPhone it just plain simple. But come on, this type of thread it's getting annoying there's a few already with help and tips on your issue search for them. Maybe you just got high hopes, or maybe it's not the phone it's you. BTW Amoled probably consume less battery but not enough for us power hungry users to see a different.

I don't think is the screen alone itself but the dual-core running at 1.2Ghz might eat more battery than your old phone with an smaller battery

You might want to install CPUSpy and BetterBatteryStats (BBS) so you can better diagnose where your battery issues are coming from. 8 hours seems very poor for this device. Use CPUSpy to see how much your device is running in deep sleep - with light usage I usually see around 80% deep sleep. You can use BBS to look for apps causing excessive wakelocks (BBS is available here on xda) to see if a particular app is causing the problem.
Unless you have a hardware problem, I don't think the display is your problem - the display on this device has a smaller percentage hit on battery use than my 3.2" LCD Aria.

Yet you've completely ignored people who have told you to get CPUSpy and BetterBatteryStats to figure out what's keeping your phone awake.
Most likely your phone is not defective, but you've installed an app that's hogging the battery or set up a configuration option that kills it, such as:
Hotmail calendar sync is known to cause massive battery drain due to a Hotmail server side bug
Some Exchange servers are misconfigured and cause major battery drain
Skype is a battery-hogging nightmare. If you absolutely have to use Skype, make sure to take it out with a task killer when you're done with it.
I haven't really pushed my device with screen-on time, however what are your idle battery drain statistics? If you have drain more than 2-3% per hour when the phone is idle (such as overnight), something is very wrong. You should be getting drain on the order of 1% an hour if you leave the phone overnight in moderate signal.

I havent ignored anyone. You assume that because I haven't responded to such comments that I haven't tried them. I frequently use cpuspy to make sure my phone is sleeping and I use bbs as well.
I'll leave the phone off the charger overnight to check it out though.
This still doesn't change the fact that HEAVY useage at 5+ hours of screen on time is absurd.
I am also planning to experiment with airplane mode and using only wifi tomorrow.

Make sure to do the following to get the most accurate data:
Top off to 100% (to the point you get the full-charged notification)
Remove from charger
Reset timers in CPUspy
Put phone down and go to bed

You can still exchange with a new one under 14 days or 30 days. 6 hours with screen on is not absurd on this phone in 12 hours. I have been with screen on with 2:45 hrs and voice with 45 min in 1 day and 8hrs with still 15+ % battery juice left.

IIRC, one of the review or comparison against iPhone4S benchmarked GS2 as 5 to 6 hours of internet browsing which means both screen on and using data. Wi-fi gives it a slightly longer battery life than cell data. Unfortunately, it didn't benchmark video playback time. iPhone4S spec says 8 hours of video. I hope GS2 is close to that. This is play video from local storage, not streaming. So, the data connection battery draw is out of picture. I managed to get 4+ hours of video playback with flight mode on with my old Captivate. Hopefully, GS2 will last longer, e.g. survive a coast to coast flight while still have some juice left for navigation.

He's not lying. I have seen 5 hours of screen on time and still had a little juice left at the end of 16 hour days. And it wasn't a one time deal. Seen it several times, though I usually don't use my phone that heavily. Yesterday I barely used my phone at all and was only down to like 85% after 16 hours.
"Long post warning"
I have really really bad battery life since I got Galaxy S2, I tried everything, never get what people claim(20hours+ battery life).
All I have got is something around 10hrs. I already using official Samsung 2000mAH extended battery.
I never liked root and flash rom but this phone made me do it .
yesterday I flashed to LeoMar75 2.7.1 with CF-root kernel (I read this kernel has best idle battery saving)
and hoping miracle will come and now..I still stuck in battery life agony
Can you guys help me determine what's wrong with my phone? I see A LOT of fellas report their phone can run for 30+ hours with 3G always on, screen time more than 2hours, internet, whatsapp and games
I basically did the same thing , I don't even do games but mine doesn't get pass 10hrs.

today I flashed the rom and kernel and I fully charged the battery then I have like 2 hours screen time for
whatsapp, engadget, FML and stuffs then sleep for 5 hours.
before I sleep, the battery has 57% left and woke up, 33% left.
I can understand 2hours screen on time drain the battery to 57% but I don't understand why 24% of 5 hours idle?
as you can see, my device woke up while I was sleeping and it's idle.
I give you guys some details
can you guys please tell me, which part of my phone is draining the battery ?
Display setting:
1. brightness : 20%
2. auto adjust display power : uncheck
3. display mode - film
Sync
I disabled Gtalk auto login and signed out Google latitude.
I also unchecked the "Backup my data" in Privacy.
I disabled Fast Dormancy.
and here are my app list.
I already did all the tricks I can find on internet to save battery for my S2 but still the battery life is miserable. I hope you guys can help me with this : (
ps. now I doing battery calibration, I think this is my last resort , I really hope my phone can do 20+hours with 3G data always on.
yeah well first of all when flashing a new rom, must wait 2-3 cycles before the battery life is maximised....
2nd of all why the need for both friendcaster and facebook ??
If the drain is still bad I would just recommend turning all data off etc...and seeing if the battery life is normal overnight (2-3% loss)...if not then something ain't right
edit; also check your wakelocks (on betterbattery stats app)

Thanks for your advice man!
do 2-3 cycles will make HUGE difference?
I have 2 facebook account for work and friends, that's why I have both friendcaster and facebook app.
I tried turn off 3G data and Wifi at stock rom(2.3.5) earlier, the drain overnight(8hrs) was within 10% so I pretty sure it's 3G data draining the battery, just don't know which app does it. (I have quite heavy incoming whatsapp msg don't know if that's the case)
sorry I forgot to capture the wakelock screen earlier but now my phone battery is completely dead,
charging it for battery calibration, perhaps I will include it tomorrow. Thanks a lot man

Try disabling facebooks sync for a day and see how battery life is then. I ran into a serious problem where my battery was drained 50% in a matter of hours with zero usage and once I remembered that I recently updated facebook I uninstalled it and everything worked fine again. I re-installed fb but disabled sync and battery life is still excellent, haven't had the chance to enable sync and monitor the battery though.

Turn notifications on for facebook but disable refresh (Set refresh interval to never). You'll get PUSH notifications instead .
are you loggdd into fb chat? If so, that should be it.
I suggest Skype.
I had Skype, Yahoo Mail, Yahoo Messenger, and Facebook installed on my phone before. Got around the same batt life as you.
Reinstalled the rom I had and installed apps one at a time. Those 4 progs are the only ones I know of I have NOT reinstalled and my battery life is usually around 20+ hrs with normal usage.

If you've never logged on then your fine. Skype has always drained my battery, but I don't use it much so uninstalled. Facebook was a battery drainer with the refresh times but now that it has push (I get notifications at the exact same time as I do on my web browser) it doesn't drain my battery at all.
Average battery life is anywhere from 20 hours to 1day & 13 hours. Screen on time is always 3 hours & 30 minutes minimum, most I've had is 5 hours & 30 minutes, that was without playing any strenious games though

Average battery life is anywhere from 20 hours to 1day & 13 hours. Screen on time is always 3 hours & 30 minutes minimum, most I've had is 5 hours & 30 minutes, that was without playing any strenious games though

wow nice tips! so you suggest even I didn't login Skype, I just let the app sit in there, it still drain battery?
I disabled the facebook refresh interval like you said and yeah I still got notification from PUSH, nice tip : )
I now calibrated the battery, fully charged, did all the tips you guys gave me.
turned on the phone for 1.5 hours with 30mins screen time, (LINE, Facebook, Whatsapp only)
the battery drop from 100% to 88%, is that normal ? (I use 2000maH battery)
with the 2000 mah battery, you should be able to hit 6 - 7hours screen on time. This does depend on your screen brightness however but your drain looks ok based on screen time. Id recommend that you charge the phone to 100% before you sleep, then let it drain overnight so you can check how much battery is drained in idle. With the stock battery, I normally lose around 1% every 4 hours when idle.
As for Skype, it did drain my battery. When I logged out it ran in the background and caused wakelock issues. 3G watchdog also showed that it would use data every 20-30 mins. I'm now using droidwall to block internet for apps that don't need it. For example I won't be downloading wallpapers from the "Flikie Wallpapers" app whilst using mobile data, so I set it to only use internet when I'm on wifi

I have really really bad battery life since I got Galaxy S2, I tried everything, never get what people claim(20hours+ battery life).
All I have got is something around 10hrs..

I have the same problem so i'm following this topic very carefully
Hope you'll find the solution !
one thing to remember as well, A LOT of people with 20 hour battery life have hardly touched the phone. Some people can get 3 days worth of battery, but with a screen on time of only 50 minutes its hardly surprising. I'd say anything over 24 hours with a screen on time of 3 hours is very nice.
Hi, this issue is specific to my NON-ROOTED Samsung Galaxy S2. I have seen other simsilar issues for other phones and they don't seem to help. My Battery doesn't seem to last more than a few hours. No more than 5-8 and it's dead. I turned off the Data and wi-fi. I set my Wallpaper to a Black background. It just sits on the desk and after a few hours it's almost dead...
What can I do to fix this?
Rooting is not an option at the moment.. I'm still reading and learning about it as I don't want to create a paperweight and/or void my warranty...
No offence mate but for a start you can search the forum and you will literally find dozens of threads on the very same subject which have been posted on here over the last few months.
Search and you'll find the answers your looking for, a tip freeze the Samsung bloatware in Titanium Backup and your battery life will improve substantially, there are many other methods to improve battery life you can find them yourself.
I get over a full day on heavy usage...
No offense taken, but most point to Rooting my phone...This is not an option for me at this time....I'll look some more, I guess...

I know...that's why I posted, but I should have said that in my original post...I'll edit it....but I did find something that I will try when I can..Phone is charging in a wall outlet right now, and I don't want to unplug it. lol...I do thank you for your effort and understanding...
I have unrooted phone and get around 17-20 hours heavy usage.
I would suggest you flash a 2.3.5 Rom via Odin as they seem to have better battery management if you haven't done so
http://forum.xda-developers.com/showthread.php?t=1075278
you dont need to be rooted to flash new roms via odin
Also advisable to charge battery till full then use till its like 1% then recharge full and so on to calibrate it a bit.
Rogue apps can eat your battery life as well so If you can afford it do a full wipe and reset if you can and see if it makes a difference.

You guys need to give more information if you really want decent assistance, there is an app called better battery stats, you want to look at your partial wakelocks section in that particular app, go get it either on this forum or in the Market, post screenshots of your battery graph in Settings>About Phone>Battery Usage and click on the time, also a screenshot of your partial wakelocks will reveal the issue 90% of the time
Also, there is no need to root your phone to achieve good battery life, unless it is found that a system app may be the cause of the poor battery which is hardly ever the case, anyone who points you to rooting to get good battery life has very limited knowledge of android and what is the cause of poor battery life...
Usually downloaded apps and user settings are the cause of poor battery, there is absolutely no need to root to be able to fix those problems.....
I noticed this one too...My stock DXI2 room tend to be a battery hogger and the display consumes around 60% of my entire battery life...
agreed I'm getting nigh on 2 days battery life nowadays maybe one and a half of moderate to high usage! certainly don't need to root and install a new ROM.

Charge your phone fully and use it as you would normally, the screenshots you provided doesn't show much, what you have to do is click on the very top where it says 22h 52m, that would take you to another shot that shows your "screen on" time in a linear graph just below "Awake" time, that's the screen that would tell us if you are having wakelocks.
Secondly, get better battery stats from the market or from this link here then set the display options to "Partial Wakelocks" "since unplugged", remember you do this after using your phone normally from 100% to 50%, this should be able to give us some insight into what is eating your battery, it may be better to let the phone sleep as much as possible, but I know it's pretty hard to leave the device alone......
You should definitely try better battery stats app. It helped me to identify the app that kept my phone awake continuosly. My battery life increased from 8-9 hrs to 15-17 hrs after uninstalling that app. I even bought the paid version from market after that. Must have app!!! Give it a shot. Its free for XDA users. But if it helps you then please do consider buying it to support the developer.
yup. My SGSII is on KJ3 stock & I get easily around 1 day & 16-17 hrs before i need a charge. This is with moderate to heavy usage (depends on your perspective) which includes:
1. Display is on roughly 1.5 to 2 hrs
2. Voice calls roughly 2-3 hrs
3. 100 odd texts
4. 30-40 mins of listening to music
5. 20-30 mins of browsing
6. 30 mins of running benchmarks
7. 10-15 mins of gaming
8. Downloads for 30 mins
8. Auto-sync & background data enabled for 9-10 hrs

Ok, I had the phone plugged in to the laptop to transfer my Memo's from my BB/Outlook over to the phone, so it only says it has been unplugged for 3 min..If you want longer, let me know, as I'll do another one tomorrow.
This one is from 49 min unplugged...
As far as that app. I'll download it now and run it for a day or two and see what happens...will post back soon!
Thanks for all your help people!!!

My non rooted galaxy s ii lasts at least on full day of heavy usage, including 3g, music, and gps. Will last 2 to 3 days if i use it conservatively turning off 3g when not in use.
make sure u have latest update thats basically all i did.
good luck.
[Discussion] Getting Great Battery Backup with JB 2 days 2 hours & still 12% balance
Getting Great Battery Backup with JB 2 days 2 hours and still 12% balance
Did lots of Phone calls and used WiFi most of the times. The 5% usage shown for Voice Call is for 2 days, so its around 90+ minutes or more. No gaming or music but some FB + Twiter and 3G browsing. Isnt this really good?
BTW, I am on P765 V20D Hongkong rom but with P765 V20A Bhaaratiya (Indian) Baseband. Pure complete stock. So bugless and smooth. :good:
No memory tweaks, just ATK and proper settings of Smart Profiles Free which automatically switches off 3G, GPS, 20% Screen brightness, Silent mode, while I am sleeping.
It is also recommended to drain your battery once a while in 10/15 days for better battery performance, so will wait for 2/3 more hours, until it drains fully.
So share your experiences about Battery usage on JB.
EDIT: Screen time is showing 5% for two days, it is just below the voice calls.
Screen timeout is 15 seconds.
Anyways I already mentioned I dont play games, so obviously I save lot of juice.
This is my business oriented phone and have configured 4 gmail ids, which keeps popping mail notifications every 20/30 minutes and for some mails I do reply from phone.
Now it is showing 11% after 2d 4h (2 more hours) . No calls came in between. Just downloaded mail when I connected WiFi again.

My battery doesn't even last a day. P765 V20A india rom. 3G is hardly used. Mostly on Wifi.. ! screen is on most of the time because i use facebook a lot.
How many hours of screen on?
My battery life is poor on JB , not sure if there's hidden bloat or just because it's v20a, it's not optimized for the hardware fully yet, we could do with some v20d loving .

It look more like the phone was on idle/stand by 90% of the time. There is no way you can get 2 days worth it if medium/heavy useage.

I have a p769 and haven't really noticed much change in battery life after Tmobile JellyBean update.
I use Pandora on 4G for 45 minutes a day while I walk my dog. Occasionally have short phone conversations under a few minutes. I check my email, sync is always on.
I usually get around a week of battery life with this usage pattern. Cut it down by a day or two when I use navigation to drive places.

On XDA no one trust each other, but if you trust me, its approximately around 5 to 6 hours in these two days. I dont know how you will believe when venkinn (above post) says he gets 7 days with 4G on and gmail sync.

@infamous_nacho, just check below quote by vekinn and comment on it. He says 7 days, which is hard to believe me too. So my 2+ days is reasonably believable, if you trust others.
If you trust me, this is my business phone (not standby phone) and 4 gmail-ids are always in sync on 2G (EDGE). So you can imaging I must be using phone on regular interval but yes I switch on 3G and WiFi only when I require. At night they are automatically off, even if I forget to switch off (smart profiles free)

This is really amazing. Have you changed battery to something thrice the size?
If you dont use 3G, then check the "Use only 2G networks" option under Mobile Networks in Wireless Networks of Settings.

My Battery Statistics in 2 days and 2 hours!!
I'm using only 2G signal, an app called Quick System Info for cleaning
tasks and cache...and of course Greenify!!
My Rom is V20D Baltics...
I managed to squeeze a little over a day out of my battery by turning the wifi setting to 'only when plugged in' then the next full charge only lasted 14 hours. I don't use my phone heavily but I text alot and use facebook here and there. I could easily get 2 days out of a full charge with ICS. with ICS my wifi was at 2-3% constantly on. if I keep it on with JB it jumps to over 25%. also, my wifi scan interval is set at 3000, on ICS I had it set at 150. anyone going back to ICS just because of this battery issue? I'm definitely thinking about it

(3%) Is about 60-70 minutes with screen on at least.
Before i start explaining the situation, I have (you can guess by title) Samsung Galaxy S4 GT i9505 model... If i tell you ROM/Kernel/Baseband, Ill lie to you because i changed A LOT of ROMs/Kernels since i got this phone.
The problems is there, no matter which ROM/Kernel/Baseband i try, i get battery drain like 3% in 2mins... and guess what, I tried everything...
First of all im not so heavy user and I have only few apps installed, like Viber/Chrome/Es file explorer pro/Guitar tuna/Adobe Acrobat and thats all....
There were times when I had more than 25-30 apps, and i tho thats the problem but NAAAAAH its not!
I turned off every battery eating thing in settings (wifi scan, 3g/4g/ location, brightness, anoying sounds, and so on)
I changed my battery aswell, still the same, new one working just like the old one...
Included greenify/amplify/GSAM Battery Monitor/Build.prop scripts but no...
Stweaks, undervolt, still the same, bad performance still bad battery life...
I can't pass 2h 15mins SOT and there is no way to get more...
When I see people getting more than 3h 30mins i cry lol
Did anybody from XDA community ever have the same problem like me, and what to do? (except buy a new phone, forget about that I can't afford it)
IMEI of s4 is 05 which is not bad quality...
Appreciate every reply or PM, thanks!
EDIT: I forgot to mention that when i boot in recovery, wipe everything and so on, it takes like 2up to 3mins, the percentage is cool, i tried to be in recovery like more than 7mins and only 1% lost even with high brightness
Bump!

A galaxy s4 is around 4 years old... Batteries degrade over time. Luckily you have a Galaxy s4 where the battery can be replaced. My s6 can hardly last 2 hours as well, but that battery is not replaceable, so I bought a charging case.

Instead of trying to fix it blind, figure out what is eating up your power, install better battery stats (u can find it on xda) and wakelock detector, let them run a day and then check the stats, find the problem first, then you can deal with fixing it. I still have a note 2 (best phone ever made imo, which I but around December 2012) along with my other devices and i get 0.8% per hour, it has constant wifi on even though I don't use it much, and I usually get a few call on it a day.

I am sure i don't have any battery eating app from playstore, and like i said, i don't have many apps installed... As far as i can see, the main problem is when screen is on, while phone is idle, its not bad at all and used guard to disable keep awake, run in backround, start at boot for almost all apps..
BBs and Wakelock Detector said that the main drain are kernel wakelocks are ... ill post you screenshoots..

Sorry I was a bit busy with things for the past few days, but could you please upload them again? All the screen shots you posted says it can't be loaded so I cant see it.

Are you using TW based rom or aosp rom? Do you have ambient display on or something like that? Or touch to wake? Or any apps or option resembling samsung AOD? Because the power manager wakelocks and services are most likely due to your screen being on, which of course will drain battery. And the wifi related wakelocks can be reduced with an app called leandroid which you can find on the playstore, to get the best out of it you have to unlock the app through in app purchase, but it works wonders. Another great app in nap time, with will force your phone into doze mode in around 5 seconds after screen off. Also there is hebf, a great app to optimize your device and manage power. But in the end if you have your screen on most of the time then no matter what you do it will consume a significant amount of power, only thing that can help in that case is lowering your brightness but I don't think there are any other solutions to screen on battery drain.

I have aosp rom, i disabled everything related to display, and even brightness is at lowest possible point, when i use the phone, and thats mostly at home, on weekends, I like before sleep to read news and so on, thats like 15mins and i lose like 25% and im sure thats not normal...
No i don't have any AOD display, when i turn off the screen, its cool, like 1-2% per hour, but the main problem is when the screen is on... and how the hell one day i have SOT 2h and 15mins, the other day i can't even pass 1h 45mins... with same setup, nothing changed, nothing specially turned on.... same usage, and no big difference in calltime, messages, etc.... wifi is turned off when screen is off aswell...
Stats are like for example 2h SOT , idle 8h.... and im sure there is a way i can get more SOT since the drainage when the screen is on, is crazy....

Quite puzzling, ok my last advice to you is to try HEBF, it has some battery profiles and performance profiles, also you can control cpu clock speed, kernel io and profiles, check to see if altering them helps you out, but other than that I am out of ideas. But when the screen is on kernel settings such as cpu speed, profiles and all that have major impacts on a device, so these are your best bet.

I set hebf on battery profile yet it heats my phone and burns battery even faster.... i tried stweaks, lowered voltage for 3 steps, phone is stable, but it doesnt change a lot... still huge battery drainage when screen is on... Im even using amoled photo.... But, when i boot in safe mode screen on time is great.... lel... im on lineage nougat ...
