Glowatt: Charging Animation

Glowatt turns your charging screen into a live show. 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.

POP-UP WHEN YOU PLUG IN

Every time you connect a charger, a pop-up drops down with the percentage to two decimals, the watts, the charging speed and the time to full. Choose how long it stays, or turn it off.

TEST YOUR CHARGER AND CABLE

See the real watts going into your battery, live. Try another charger or cable and compare in seconds. The ring changes colour with charging speed, from amber Slow to teal Normal, green Fast and pink Super fast, so you can tell at a glance.

BEAT YOUR RECORD

Glowatt remembers your fastest charge ever and celebrates when you beat it. Unplug and a charge summary shows how much you charged, how long it took, the energy and the peak watts, ready to share with friends.

WHAT YOU SEE

• Battery percentage with two decimals, moving as the charge moves

• Charging power in watts, and the watts your phone uses when unplugged

• 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

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, the fastest power this charge, time since restart, and this charge's energy, peak and average watts with a live graph. Anything your phone does not share is marked Not supported, with an info button that explains why. Never guessed.

SCREEN SAVER, NIGHTSTAND CLOCK AND OLED BLACK

Use Glowatt as your screen saver, and a charging phone shows its charge and the time instead of a dark screen. Show a clock above the ring and keep the screen on while you charge on your desk or nightstand. OLED black switches to white on black with most pixels fully off.

LIVE WALLPAPER

Set Glowatt as your home and lock screen wallpaper, on your own photo or its own gradient. Plug in and the ring comes alive with your charge. The rest of the time, a calm ring shows your battery.

MAKE IT YOURS

Four ring styles, colour themes and clock styles, plus settings for screen on, OLED black, the charge summary and record celebrations. A Quick Settings tile opens Glowatt in one tap. Available in 12 languages.

WHERE THE NUMBERS COME FROM

The decimals come from your battery's own charge counter, read through Android, and 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.

PRIVATE BY DESIGN

• No internet access, so nothing can leave your phone

• No account, no ads, no analytics

Glowatt shows your charge. It does not change how your phone charges.
