Support.
Most questions are answered below or in the FAQ. For anything else, write to us and include your phone model and operating system version.
- Data totals are empty on Android
- WattByte needs "Usage access" to read mobile and Wi-Fi totals. Open the Permissions screen in the app or the system setting Apps with usage access, and switch WattByte on. Per-app data needs the same permission.
- Numbers are marked with a tilde (~)
- The tilde marks an estimate: the phone did not report a charge or energy counter, so the value was calculated from the battery level and the design capacity of your model. On iPhone every energy figure is an estimate.
- Battery capacity unavailable
- Your phone model is not in the device catalog yet. Enter the design capacity by hand in Settings, Battery Capacity; the energy figures will use it from then on.
- The electricity price is wrong for me
- The automatic price is a national household average. Switch to a custom price in Settings, Electricity Price, and enter the tariff from your bill.
- Export or delete my data
- Settings has Export CSV, Export JSON and Reset Statistics. Deleting the account from the Account screen removes the cloud copy as well.

We answer in English and Polish. Do not send passwords, exports or screenshots with personal data unless we ask for them.
Before you write
- Read the FAQ.
- Note your phone model, the operating system version and the WattByte version from Settings.
- If a number looks wrong, say which screen and which period.
