Hi. Can someone help me with my problem?
Im facing massive battery drain even after wipe, im only getting around 3/4h SOT. In BBS, 2 alarms are weird Job.delay. And job.deadline. I have wiped my phone, installed last version of rom, after that i have restored my apps. Problem still exist. Next i have installed kirasakura kernel and then frozen every of my apps, and its still there. After night im losing around 10/20% of battery. Im attaching some screens from bbs. Thanks in advance for every help.

i'll try to help as much as i can. install servicely and look at running services. if you see something weird, stop that service.
also, i see you're using bluetooth. that thing drained my battery as bluetooth would stay turned on even when it says it's off. what you can do is turn it on and off and it should stop bluetooth service from running.
in servicely you can disable apps from running in the background. maybe some app is running full throttle even tho you thought you closed it.

another thing you can check is if xmode is running. once i had system turning on xmode on even tho i closed the app that used it.

as you're rooted, check with some kernel manager what cpu governor is turned on. maybe the system is stuck in performance mode.

lastly, you can check your battery capacity. maybe it needs calibration. that could also result in battery drain as it's not charged to the max.

also, android 10 is generaly badly optimised for our phone. it has some good features, but powerwise it's not that efficient.

if nothing works out, i'd suggest returning to latest android 9 and do battery calibration.

Thanks for answer. I have installed servicely but im not see anything suspicious. Xmode is off, governor ist in performance mode. About battery calibration, i dont need extra juice from my battery, i want to lose 1% over night, not 20%.. Probably around July/august everything was fine, my battery last for almost 3 days, now something eating it alive and i dont know what is it. Can i somehow check which app generate this "job" alarms? In BBS its "Android" only..

battery calibration isn't about extra juice, it's about system showing the right percentage. you could lose a lot of battery because it doesn't get charged to its max capacity.

there could also be a problem with the lastest update. when i was seeing a lot of battery drain, i had it because system constantly used location services. check in services if there are any location processes running. also it could be because of network. maybe your phone is constantly switching between 3g and 4g.

you can also check in the kernel manager what is your current battery draw in mAh. if its always over 300mAh, then you have a problem.
look for a wakelocks running in the background and disable and enable some to get them resetted.

Probably u have solved my problem. Even after turning off location, i still have some running services with location in name. I have blocked all of them in servicely and after night i lost 1% of battery. I will check now in later days. Thanks a lot :)

A reload generally solves nothing and wastes time. It's always best to find the root cause(s) and address them directly otherwise they tend to reoccur.
Viruses (never had to), boot loops (prey it works🤣) and old loads are the only times I reload.

yeah i thought it could be that. it's also worth checking if you have "find my phone" turned on. it's somewhere in the settings. search for device admin apps. if you see any apps turned on as device administrators, turn that off. those could also drain battery

After couple of days, problem is back. No new apps, 3 days was good, 0/1% drain in night, now its again about 15/20%. I will just sell this phone becouse i dont have any more patience...6000mah and my OP3 with half of that value can ez get about 5h sot. Aktually im getting about 3/4h sot and 3h calls. When i have bought this phone i have had about 10 h SOT and 5 h of calls in 3 days of usage. Never again gonna buy phone from asus. Thanks guys for every help :)

i wouldn't condemn the whole brand because of one phone model.

also try going back to android 9 and check how's the battery drain without any apps installed. then start installing your apps and monitoring if the drain will increase.

i'm currently on android 10 and there is some major problem with battery regulation. raw capacity goes below zero when the percentage is below 10 percent. no wonder the whole system starts stuttering when battery level is below 3%.
