Bad battery life - OnePlus 7 Pro Questions & Answers

Hello Guys,
my 1+7pro seems to have a really bad sot.
I get barely 5 hours with [email protected] and 90% only WiFi.
It's rooted with Smurf kernel+XXX not limits ROM for Magisk.
All of them are updated to the newest versions - no app seems to walk in the background draining battery.
AccuBattery measures the battery health is about 3400mah left after just 5 months now.
I never charged it over 100% , never used Quick Charge and never let it discharge beyond 20%.
Any suggestions ? Maybe a defective battery?
In the other forum sections they get 6-7+ sot that's why I'm so curious...
Best regards

Have you been flashing the phone recently...when was the last time you left the phone as is...everytime you flash/ clean cache etc..the phone will need a few days to settle down...If all's settle down and you are still getting bad battery...get it to a service centre and see if they can fix it..

how much battery back-up do you get?

how much battery life do you get? I seemed to have very less battery life. Just wanted to know if there is some problem with my battery
Wow. Two battery threads from you. That really makes us want to help you. Not to mention all the details you provide if somebody did want to help you.

With the overwhelming wealth of information you give us to help you diagnose... Yes, yes there is definitely a problem with your battery. Buy a new battery. It's what I just did.

ROM: ICS( MIUI ROM). Within 2 hours and 33 minuts the battery level has dropped to 78%. Is it because of the ROM I am using? I have also experienced sudden variations in battery level. When the battery level is somewhere around 60s when i reboot to recovery the battery suddenly drops to below 20s .

That's about right for ics roms and moderate use. I consistently get about 10-12 hours with 1-2 hours of screen on time. Rebooting to recovery screws up the battery readings but you should see it creep up and come back to normal eventually.

Try the Proton kernel if you haven't. I used to get 10-12 hours similar to what you said. Proton improved that for me. Also use Autostarts app or Gemini App Manager to stop apps you don't need from automatically starting.

From what other people have said, inconsistent battery levels on reboot generally means that your battery is on its way out. You can see by using Battery Stats Pro or something similar that the voltage will sometimes drop by 200ma (at least, mine does) on a reboot. Which is why I ordered a new battery... which would have been here last week if it hadn't gotten lost a state away. Stupid Fedex.
I'm running pacman for now and using greenify to keep maps and google services from killing the battery in 5 hours. It went 15 hours the other day but I hardly used it at all. I have another battery but I hardly use it, it's a 1500mah and it doesn't last nearly as long as my good old stock battery which is in fact a bit swollen and slowly dying. I guess that recovery battery thing is like the distant early warning of impending battery death.

Having headaches with my battery life

So I'm getting pretty bad battery life on my Spring Galaxy S6 Edge. I got the S6 last week and I can still return it to Sprint and get a different phone. (I'm looking at the G4 right now). I've been reading almost every battery thread on XDA and reddit and I just can't figure out how to get better battery life. I'm running the latest stock software. I am not rooted. I've already tried a factory reset and disabled all unnecessary apps.
Right to the point, I get around 2~2.5 SOT on my phone usually with only Wifi on, low brightness, and location set to battery saving. Now, I'm happy with how the phone drains when I'm actively using it. I got about 50 minutes SOT of reddit, instagram, facebook, etc and it drained about 15%.
What I'm not happy about is the idle battery drain/screen off drain. On multiple occasions, I charged my phone to 100% and let it sit over night. I would almost always wake up around 90 or 91% with around 8-10 hours of sleep. Other times, the battery just drains at a crazy 5%/hour. How do I minimize idle battery drain? It's driving me crazy. I don't think this is a problem with the S6 specifically, as I had this problem with my M8 running lollipop before.
I look at CPUspy and it looks like my phone is going to deep sleep around 60% of the time. I'm would like that number to be higher, but I'm entirely sure if 60% is good or not.
On GSam, I always notice that Android System and Kernel are top of the list. Not sure how to tame those. Other apps seem to be doing okay.
So I'm looking for tips and advice on how to make sure I'm getting the best idle drain without going into airplane mode. I know that if I get get idle drain down, then this phone or really any phone can last me all day and get 5-6 SOT. I also read somewhere that reflashing the firmware might help, but I'm trying to see all of my available options before I do so.
Thanks everyone!
EDIT: I'll also try to add screen shots after using it for a few hours!
You may have a defective battery. Return your S6 back to Samsung for warranty replacement.

Disable Location service when you don't need it, it drained lots of battery and install the above ver of Google Services will help battery. A new battery will take at least two weeks to completely optimize the battery.

Sorry, I don't buy that it takes two weeks to fully optimize the battery. I'm not going to take the chance and wait it up and hope it gets better when I can go back to the store and get a new phone.

Battery life

Hi guys .
Just purchased this phone... loving it . But I'm noticing the battery life is plunging when I'm using it. 25 mins ago was on 100% now on 88% , do we'd think it's a bad battery , or is this normal... running Marshmallow...
Please advise me .
Thanks
Emma xxx
Its not normal.
Wait for a day or so. Could just be initial indexing and background processes setup.

No, this is normal for the Note Edge. It does not get good battery life. I get around 2.5-3 hours of screen on time, and your usage would be consistent with what I'm seeing as well.
It used to get decent battery life, but with updates and such, it has been reduced dramatically and I haven't been able to fix it with new batteries and even resetting the phone multiple times. I'm also running Marshmallow.

Battery life issue?

My pixel has been having inconsistent battery life at 100% after charging it will sometimes say 19 hours left then sometimes at 100% it will say 9 hours. Is anyone else having this is with the pixel? Is there something I can do to help my battery life I did a factory reset after the Oreo update and have most features turned off. I've had the phone for about a week now with the 100% battery life being drastically different with each charge. I don't have FB mostly still stock apps aside from a game I play. Thanks in advance for any help.
@subvapor It all depends on how you use your phone. This sounds normal and not an issue to me. The estimated battery life it gives you is just that; an estimate. Try this: charge to 100% and use your phone normally until it gets down to around 10% or so. Then check your screen on time in battery settings. I would say 4 to 6 hours is pretty average when it comes to the pixels.

Thanks for the help I get around 3 and a half hours to 6 hours of screen on time. So I guess I'm getting good battery life out of it. I'm just trying to make sure everything is good on it as I got it as refurbished on Amazon with a 90 day warranty. Loving the phone so far though!

Yep that sounds about right. If you take it off the charger and then immediately start using a battery draining app that will really screw up the estimation too.

Experiencing battery drain on new phone

I bought my OP7 7 days ago , I have been experiencing poor battery life from day 1. SOT is around 3 to 4 hours , standby time is around 22 hours. If I leave the phone idle for an hour , the battery percentage drops 4 percent without any activity . I do remember receiving an OTA update on the first boot , I don't know if that was the culprit or I have been sold a lemon. I have waited for a week hoping that the battery life would improve after a few charge cycles but there has been no change.
Is everybody else facing the same issue , especially those who are on 9.5.x ?
I have to say that i do not experience any issues like that. The overnight drain is minimal, a few % over 8 - 9 hours, and overall the screen time is as expected (i daily play some extremely CPU heavy games for a couple of hours and i still get around 5 hours of screen).
I'm also experiencing the same issues. When phone idle abnormal battery drain.
Can you tell me if the phone with the cellular data turned off, uses data from your plan? Can you see that?
I had same issue with my phone so then I returned it to Amazon and I received replacement which is working fine and giving good battery backup.

I made 2 returns, I'm now with the third phone and still had the same issue. I'm losing my mind how is that possible. And for sure is all new phones with different imei.
Every user has different usage profiles.
If your phone is rooted install Better Battery stats or FK to get detailed info about the rogue process that may be consuming more battery than it should.

I'm not a heavy usage user.
I'm not rooted but installed a similar app. I'll collect data and will post the screenshots.
