This is the first Time when after update my 6t drains battery very fast
Have you tried looking into this thread? https://forums.oneplus.com/threads/unified-op6t-battery-and-heating-thread.952987/
Yes, i face it too on my 6T..!!!
when did you update?? usually you need to wait 2\3 days after update.. to check if the battery is good or not
I had this same problem and I noticed it right after the update... after the update I cleared the cache and charged to 100%... but the battery drain still continued... I decided to clear the cache again at around 25% battery... and then I charged again and left it charging at 100% for some time... the battery drain seems to have disappeared now...
please check your battery setting, and find the processes and apps that heating your battery
Just checked... nothing out of the ordinary that is draining the battery...
