Battery draining

Model: ZE620KL

Frequency of Occurrence: Reguler
Rooted: No
APP Name:

After updating latest Android 10 beta 100.44.98 my battery is draining super fast. So much so that it just gives me half the time it used to provide. And the charging time has also increased by 30-35 minutes per cycle.
Please answer as quickly as possible.
Facebook and zenui is also crashes time to time.
