iPhone 13 Battery drains faster

Hi Bro when I updated to 16.3 I feels like the battery is draining very fastly. Is there any possibility to downgrade my IOS? And also please tell me the things which I have to face while doing this.

Hi bro, you may try these battery saving tips,

You will see good improvements. See for one week atleast and If problem continues then we can try ios restore. Downgrade is not possible now bro. But ios restore will definitely let us see good improvements.

Thanks for your response bro, I’m already following these tips from your videos.
Mine is a 3-month-old phone I watched your videos regarding the 16.3 updates and after that only I updated. Still, I have 100% battery health but on standby, it was a 2-3% loss of charge in the night to morning time but now it’s like a 10% battery loss.
Please suggest me some other ways, bro.

And also Bro my charging routine is like I use the phone until It drains to 20% and then Im charging my phone until 83-86%. Please tell me if this is ok or not.
