Battery drain after Oreo update? - OnePlus 5T Questions & Answers

Hello I recently updated to the latest firmware and it seems like the battery is draining unusually fast. I did start using moto360 with it as well, around the same time as the update.
I've attached a screenshot, is anyone else having the same issue?
Is there a fix for it?

Did you do a clean install or a dirty flash? It seems most people that have problems did not do clean install.
I did a clean install. My battery life on 5.0.3 has actually been better than 4.7.6.

that's probably it. I'll report back after I clean flash

Clear your cache in recovery maybe?
I feel mine is actually better than 4.7.6 too.

[Q] [Help] Random Reboots

Hi, I've been suffering some random reboots (about 3 per battery cycle) and after every reboot battery goes down drastically. I've changed the ROM and kernel and it still happens. I attach a photo of the battery life (you can see when the 3 reboots happened in the interruptions of the graphic) and a catlog (it's my first catlog so I'm not sure what to do). If you need any more info or the previous part of the log just tell me and I'll provide it.
Mine is a GSM gNEx and now I'm on Rootbox ROM (31/01/13 version) with ak 670.42 dummy kernel but as I said, it also happened in CM 10.1, AOKP, PA and with ak purity, leankernel and franco kernel.
Thanks in advance and sorry for my english.
it could very well be the phone itself. i had something similar happen on my toroplus and havent had the problem since i replaced it.
It could be your chip, but let's look at a couple of things first.
1) Are you dirty flashing by any chance?
2) Have you gone 100% stock and see if it happens there?
Nope, I haven't tried 100% stock, will try tomorrow (after doing my last exam of my degree). Also I've just had a reboot at 82% battery and the first one yesterday was at 82-81%. Is it a coincidence or can it be a hint? Maybe it's the battery...
Also I've been doing a full wipe between ROMS, no dirty flashing except for upgrades on the same ROM (just upgraded rootbox to latest JOP40G)

Well I would do 100% stock boot, recovery, ROM etc... and see what it does.
I doubt it's your battery.
My random reboots stopped after I stopped flashing custom kernels. Try a clean install and keep the kernel that came with the ROM and see if you still get them.
Thanks, then tomorrow I'll try going back to stock ROM + kernel and see if it gets solved, if not I'll try with full stock.

[Q] 4.4.3 Battery Issues?

I'm holding off the update of 4.4.3 because I've heard that battery life decreases, can any body share their experiences of battery performance after the update?
I have a TMO M8 complete stock. I did my update last week and also added the GPS update, then cleared cache from system recovery.
I have seen an improvement in battery life.

ospm_wake_lock & battery drain

hi..anyone know how to fix this wakelock? it keeps on while screen is on use and stops when screen off..
hello..anyone know how to reduce or fix this android OS battery drain..this thing is ridiculous and kills our battery.. I already tried to find apps or source that may cause this drainage but useless, I also disabled most of the bloatware and greenified most apps including gapps but still no luck..wiped cache and art/dalvik cache, factory reset, but android OS still running..maybe only 5.1 update that may help to solve this problem..please asus dev help us..this is madness, 3000mah battery seems to be reduced to half by this crazy thing..this must be rom or kernel related problem and not gapps or gps issues..
Yeah, same here. Seems to be an issue with 5.0 and will be resolved with a new update, hope we get it soon.
> Tested on latest firmware v2.18 and I get the same ospm_wale_lock that may cause Android OS to be running all time. But still undetermined what causes this kernel wakelock.

How can I completely restore my phone and reflash latest miui with all the firmware drivers?

I'm absolutely losing my mind please help
A little story time, skip to the end for my question;
So, how to start - One day I unlocked my bootloader, went for some android 11 rom and all was fine. Then android 12 was released and I downloaded the crdroid 12 rom, where I was experiencing some battery drain issues. So I downloaded pixel experience rom. The Bluetooth died because of this rom's cursed source code. I flashed the latest miui fastboot rom and the Bluetooth issue still persisted (remember this for later - not all the drivers flash with the Rom). I fixed the Bluetooth issue by switching several miui roms, also made a guide if you're interested. That fixed the Bluetooth issue and I went for pixel plus ui rom. It was a bit laggy, so I switched to the shiny new Evolution X rom. It was amazing, so much stuff co customize, etc. Well, i experienced another battery drain issues, so I just went for the stock miui with magisk pixelify module. Im pretty fine with this rom, and I thought the problems are gone, because it stock and everything should be fine. Well no. The battery drain issue persists. I was wondering what even is happening, so I opened battery settings. That said that the top apps wasting my battery is screen, Google services and android system. I downloaded a CPU usage stats app, which showed me that the cpu usage is at 99% (I think it's correct as the phone is overheating). The app with most cpu usage was using only 1%. I don't know if this is a firmware bug or whatever, but I think some rom broke it and the latest stock miui didn't overwrite that driver, as written above with the Bluetooth issue.
So, how can I make my phone be as it was released from xiaomi with all the drivers to actually use the hardware correctly?
Thanks in advance for any replies, I'm seriously going to throw my phone out of the window
Also the way how I install the stock Rom is by downloading the latest fastboot rom, extracting it and executing ./flash_all.sh file.
SOLVED! My problem was because of my credit card. I have my cc in the phone case. The cpu was going insane because it was constantly detecting the card and loading info from it. Literally turning off NFC fixed this whole issue. Bruh.

Question LinageOS Battery drain in last few updates of 19.1 (currently 19.1-20221008) (resolved)

Since the last few updates, even on a fresh install with nothing installed. My LineageOS in Alioth has been using 7% to 11% /hr of battery on a fresh install with no extra apps added. Tried doing a clean install, reset to factory, even tried reseting battery stats. Sadly cant do anything about it and I'm not being able to go back to versions I knew worked OK (19.1-20220723 for example since i dont have an img to use and lineage page only have the latest).
Most battery, about 55% is consumed by Kernel. Has anyone had the same issue?
Not sure what else to do and really don't want to go back to MIUI.
I got similar issues a few Updates back, it was related to some Magisk modules I used. After removing them the battery drain stopped.
Try getting the logcat output and see if something is reported there.
Also make sure you are using the right firmware.
Thanks for the advice Boracho, but this is happening on a 100% clean install. Not even gapps on it.
Did clean installs of both OS and recovery versions 19.1-20220917, 19.1-20221001 and 9.1-20221008... all had the same problem. Finally remembered I had 19.1-20220723 in a pendrive. Installed it. Works just fine. Battery problem is gone.
Disabled auto updates. The end.
