Max onscreen time for Note 3 S800?

Hi,
I want to check my battery's condition, so asking you guys the onscreen time of ur note 3.
Mine is around 5.5 - 6h for mix use 40-50% brightness, Hyperdrive rom, with:
2.5h gaming (Summoner war)
1h facebook
2h web (reading news)
Under 20 texts and fone call
Is it bad? Do i need to buy a new battery? Because my fone is used. So i dont know how good the brandnew battery was.
On an average day of moderate to heavy use, i get anywhere between 4 and 7 hours screen on time, usually around 5. Auto brightess, wifi always on and heavily debloated.
Your battery usage sounds fine

Why my SOT is so low?

I can hardly get 4.5-5 hours of SOT, some members can get up to 6 hours of SOC...
The phone has the lastest stock rom update with xposed and root...
Can someone help me?
I have the N910F (International).
android has something which is keeping it awake. probably xposed.
Another user whining about 4 hrs of SOT when a lot of people (including me) are barely getting to 3 hrs with all the possible tweaks already done. Honestly, I don't think you'll find any luck here man, just be happy with what you have - and those 4 hrs are not that bad as you think.
S-Health makes a massive hit to battery life. I gained over an hour screen on time with that disabled. I also believe auto brightness makes a big difference to battery life so I set it to manual low brightness. I also turn off all sensor stuff like smart stay and settings that dynamically alter brightness. I also got rid of adaptive display.
5-6 hours screen on is easily doable for me if i'm not playing games.

[Q] N910C Battery Life

Can users with 910C tell us what is the battery life on that model?
I was on 5.0.1 stock PDA N910CXXU1BOC3 and CSC N910COXX1BOC1, battery life was terrible, after that i downgrade to 4.4.4 stock PDA N910CXXU1ANK5 and CSC N910COXX1ANK2, i made a full calibration after.
My screen time in 22 hours is 2h and 30m, 37% battery left. Rest was idle. It is so, so little. In standby i got 0-1% in 10h, so idle standby is very good. Band was set on GSM only, all sensors deactivated.
Any advices? What are your times gentlemans on SM-N910C model?

I'm on 5.0.1 BOC3 and every day I have WiFi and Bluetooth on all day, screen at just under 25% brightness (unless outdoors). I regularly get 6 hours SoT, but usually finish the day with 4-5 hours SoT and about 20% battery left. Today so far the phone has been on 4 hours with SoT of 1 hour and I have 89% battery left. Did you do a factory reset before/after moving to Lollipop? Coming from an N7000 I've been very pleased with the battery life on the N910C.

try greenify, it improved it a lot! (from 2hours to 3.5hours)
I have Greenify installed, but honestly don't find I need to use it much. I have automatic hibernation turned off, and just hit the widget now and again when I feel the need to close some persistent apps. (I am not rooted).

Pff. Thats splendid. Mine goes 1% every 1-2 minutes when im use it. I tryed 3-4 roms, different base, LL and KK too. Same battery life. In standby is very good. Its drops when i use phone. I charged 3 h and 50 mins ago. Now i have 79% with 55 mins of screen. I belive it is very weak. On this percentage i will get 3 h of screen
Sounds like maybe some app you have installed is causing problems, or could be a problem with your battery. Have a read through some of the other threads on battery life for tips and possible solutions.

buy this phone

plz tell me about this phone,everything especially battery life.ty
great phone, battery life on stock rom gives me around 30-35 hours with 5-6 SoT

Battery life in Android Nougat

Hello. I make this thread to share your battery lifes in new system. In Nougat i hlave only 4-4,5 hours SOT. On MM it was 5,5 hours. Please post your SOT and Battery lifes.
I am a moderate user with stock 7.0 E6553 Customized TR - No Root and Locked Bootloader ( I dont know how to unlock it . I don't have facebook and messenger app. I get 3h SOT. If I use greenify with aggressive doze, I take 4h SOT. But notice what I wrote, I don't use facebook and messenger. I use only opera mini, whatsapp, camera, calling and messaging. I disabled or uninstalled all other bloat apps.. My biggest battery drainer is "phone idle". I dont know how to prevent phone idle drain.
When I first flashed nougat, battery was better, but my SOT have decreased significantly for nowadays. I dont know he reason, maybe my battery need to be replaced...
Thanks for your reply. I hope that update in april will fix battery drain issue.

I always use the device with stock settings only!! Mine is customised IN.. And I won't charge the battery above 90~
After updating to Nougat with Xperia companion... I used the device for a week and then did a reset.. It solved some minor bugs!!gud luck

I get 3 hours and 30 minutes too. I've only gotten 5 hours once.
Don't you people have any apps running in background or anything? I have NEVER EVER seen any SoT close to 6 hours on any phone.
Removed my charger 7 hours ago, screen on is 34 minutes and battery at 71%.
Same battery drain to me

34min and 71%? In my way, i lost 20% in 1 hour of usage...then i lost around 30% to get 2hours of SOT, and 30% to get 3H SOT...at 20% my Stamina mode turn on, and i can get 1 hour to get 4H SOT...
80%-1H SOT
50%-2H SOT
20%-3H SOT
5%-4H SOT(with Stamina turned on)

This is something odd... I never seen any z series from z1 with 4hrs sot!! They hav given me a minimum of 5 hours!! And nw I.settled with z3+ (NOUGAT)with minimum 5 hours sot and max of 6 hrs!!
U can see in this ss!! A very near 3 hrs sot on 50% consumption of battery with aggressive usage!! And remaining 50% can easily make it to extra 3 hrs!! Since Stamina wil kick in at 15% i can get morethan 6 hrs sot (6 hr ~10-20 mins)

Me too, but i was with 6.0, and cant play 1080p60 on YouTube, just 720p60.
Nougat ruined my device, so i put 6.0, and everything got better again.

You manage to have a great power backup 6hrs sot is like double the sot i get on my z3+. I have attached the screenshot of my device, i can 19hrs remaining on your device for 50% battery remaining but in my mobile i can see 69% batteru remaining and 11 hrs left. Amd by the time i created the post that took hardly 5 mins i lost 5% of battery capacity. Pleaee check my screenshot attached. I can see good health of battery in service test. I dont know what's wrong with this mobile but this battery sucks. I always put my display at 0% brightness. I can see phone idle eating up my batteru. I habe put greenify aggressive doze, enabled auto hibernation. seems to be of no use.?
I hope u can help.
P.s: ihave reset the device twice but no use.
On my xperia Z3+ I got max 2 hours SOT with the data connection always ON and about 35-40% of backlight, is it normal?
