Hello. Yesterday i got update to android 9 and something happened with my earbuds. On android 8 the earbuds usually drain from 100% to 0% for 2.5 hours. And today on android 9 it was barely 1.5 hours active time, tried three times, wiped partition and bluetooth cache, removed and paired again. Any ideas what happened apart from the problem of earbuds?

Hi chrono23, Do you mean the earbuds' battery drains? today on android 9 it was barely 1.5 hours active time--> Were you using it nonstop for 1.5 hrs? Could you tell us how you use the earbuds? (Which app) Could you kindly tell us the brand and model of your earphones? Thank you 🙂
