Idle Battery drain &Whatsapp calls not working properly after the A15 update

[kirancrazy1]

The battery drain is high during Idle time and whatsapp calls keeps get dropped or Mic is off for few mins . 

Hope A15 should have been a good update but nope .

Battery drain could be because of the Android 15 update now optimizing in the background, if this continue it could be a good idea to do a factory reset to have a fresh install of the phone.
