Phone battery replacement: forget everything you know

Some of what people know about phone batteries comes from older battery types. Today’s lithium-ion batteries do not need to be run flat; many phones manage overnight charging themselves; and a high mAh figure on a label is not always the real capacity. Heat is one of the things that wears a battery most.

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.
