Battery running out too fast?

Batteries wear out with use.
Separate how worn it is from which apps use the most power, and you'll know whether to replace it or change settings.

What it does

At what wear level should I replace it?

Consider replacing it when battery life is short enough to be a problem. Wear of 40% or more is flagged as critical.

Does it work on desktops?

The battery item only appears on laptops. Everything else works on desktops too.

After installing, click the tray icon and your first diagnosis is already done.
