After reading this give Feedback to BETA community first. It would be really helpful for all of us.After Installing BETA android 10,
Battery performance is not that good. I was able to use 6-7 hours screen time frequently (Not Always) and now it's hardly 4-5 Hours. I was able to use my phone almost 24 hours on single charge and now I have to charge my phone twice in a day.
I was facing the same problem but after doing reset on 4th beta update I am getting 7 hrs SOT and idle time going almost 2 days. I would suggest reset once to get battery on normal life
