Well we can’t do anything regarding the battery life for now but you can see my screenshot nothing team has suggested some methods to improve batter life..
I am sure they are working on the battery life problem because too many users are facing problem so let’s be patience and let the Nothing team do their work…
Regarding your phone burning up avoid using the phone when charging
Avoid using heavy load demanding apps like games or another application under direct sunlight and keep the phone somewhere not so warm just moderate temperature…
That’s it for the burning too much problem hope it helps
