========================================
My phone discharges in 1.5hrs and again it takes only 1hr to recharge. This issue started occurring after a new update i got in May 2020. Has anyone else been experiencing the same recently ? Please help me out. It's only been a year since i got my phone and this starts happening.

needs to recharge everyday (it last for about 26 hours IDLE, it lasts only for about 5~ hours if I use the phone constantly)

idle drain is huge and the battery drains even if the phone is turned off
