Question: battery use
I think my battery has problem
I bought the Iphone8 last Sunday.
Yesterday, after full charged, i used my phone for 3H 53m but i got 40% left.
So i lookd up the internet about this, many people recommanded i need to use up my battery and recharge fully and i did.
But now I ve been using my phone for 2h 20m right now and i have 76% battery left.
There IS something wrong right?
Right now I am having business trip in Korea.
What should i do?
