How to Test Your iOS Battery Drain

Head on over to Settings > General > Usage and check out your times.

The key to look for is that your Usage time should be significantly lower than your Standby time (…)

So here’s the test:

1. write down your usage and standby time, press the sleep/wake button (…) to put the device to sleep, and
2. set the device down for five minutes.

When you come back, take note of the change in time.

• If your device is sleeping properly, then the Standby time should have increased by five minutes and your Usage time by <1 minute.
• If your Usage time rises by more than one minute, you have a drain problem.
