Does performance improve after a battery replacement?

When a worn battery cannot deliver peak power, an iPhone may slow itself to avoid shutting down; after a battery replacement this is removed and the phone returns to normal speed. In the first days, background tasks and the percentage settling in can affect battery life. If problems continue, the battery is checked.

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
