Hi @
SnRohit,
Hi, when you say that your SOT(Screen on Time) has gone down, can you share the SOT after trying the below:
1. Charge the battery to 100% & use as per your normal usage pattern
2. When the battery strength reaches 10%, go to settings = Battery => Tap on the battery icon & share the graph
3. settings => Battery => Check the screen & share the same
Make sure your software version is on the latest which is .99
Factory reset your phone once, if not possible you can check if there is any App which you recently installed which may cause this issue.
