iPhone battery draining for no reason: what to do

If your iPhone battery drains for no reason, first check Settings › Battery; it shows how much each app used in the last 24 hours and recent days. For a few days after an update, background tasks can drain the battery faster. If Battery Health recommends “Service”, the battery should be replaced.

FAQ

Frequently asked questions

01

Why does my iPhone battery drain for no reason?

Background apps, location, weak signal or post-update tasks are the most common causes. Settings › Battery shows which app uses it.

02

What if the battery drains fast after an update?

Wait a few days; it usually settles once background tasks finish. If not, check the battery screen.

03

What if Battery Health says “Service”?

The battery capacity has dropped clearly; a battery replacement is recommended.

04

Will a battery replacement delete my data?

Data is usually preserved during a repair; still, you need to back up your data before the repair starts (backups are the customer’s responsibility).

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.
