Have other users experienced that the battery drains faster with the new update? I usually take my phone off the charger at 10 pm, turning off all services (mobile data, wi-fi, etc.) and in the morning, when my alarm goes off at 6:15 am, I'm usually at 95 percent. 88 percent with One UI 5.1 system, and even during daytime use, the battery drains noticeably faster.
Wipe cache partition seems to have solved the problem.
