1. Make sure your mobile signal (Battery - tap the graph - look at the bottom of the page) is green. Any less signal costs you more battery.

2. Start the phone in Safe Mode. Fully charge it. See how long it lasts. If that lasts longer, some app you downloaded is draining the battery even when you think it's not running.
