Battery percentage to two decimals and live charging watts, in a glowing ring.
Glowatt turns your charging screen into a live readout. Plug in and a glowing ring fills with your charge, the battery percentage counts up with two decimals, and the power going into your battery shows in watts, the same unit chargers are sold in. WHAT YOU SEE • Battery percentage with two decimals, moving as the charge moves • Power going into the battery in watts while charging • Unplugged, the watts your phone is drawing right now • A ring that fills with your charge, with particles flowing in from the charging port • A burst of light the moment you plug in • Voltage, current, battery temperature and a time to full estimate, one tap away BATTERY DETAILS Swipe up for a full readout: battery condition, charge cycles (Android 14 and later), the capacity Glowatt measures from the charge counter, charger type and the maximum it reports, and this session's energy, peak and average watts with a live graph. Anything your phone does not report is marked as such, never guessed. OLED BLACK Switch to white on black with most of the screen's pixels fully off. A thin white ring and white numbers, nothing else. Made for OLED screens. QUICK SETTINGS TILE Add the Glowatt tile to your quick settings to open it in one tap and see your battery level at a glance. KEEP THE SCREEN ON One button keeps the screen awake while Glowatt is open, so you can leave it on your desk or nightstand while you charge. Turn it off and your phone sleeps as usual. WHERE THE NUMBERS COME FROM The decimals come from your battery's own charge counter, read through Android, and they never run ahead of the percentage in your status bar. The watts are the power going into the battery itself, which is a little less than your charger delivers, because the phone uses some of it while the screen is on. How fine the readings are depends on what your phone reports, and Glowatt adapts to phones that report in different units. PRIVATE BY DESIGN • No permissions at all • No internet access, so nothing can leave your phone • Nothing runs in the background: it works while it is open and stops when you close it • No account, no ads, no analytics Glowatt shows your charge. It does not change how your phone charges.
