ChargeWatch - Charging Monitor

ChargeWatch shows how fast your phone is charging right now, in big, easy-to-read numbers, on supported devices.

KEY FEATURES
- Real-time charging power in watts (W), with current (A) and voltage (V)
- Battery level on a glowing ring
- Estimated time to full charge while the screen is off
- Battery temperature
- A persistent notification with the watts and battery level, so you can check it without opening the app
- No ads. No internet access. One-time purchase

WHEN IT HELPS
- Compare how fast different chargers and cables charge your phone
- Check whether a new cable made charging faster
- Glance at your charging speed while you charge

GOOD TO KNOW
- ChargeWatch shows the power your phone's battery is receiving. It will differ from the numbers shown on a charger or cable. For example, a charger may show 20 V, but the phone converts it to about 4 V inside, so the app shows about 4 V.
- Some power is lost as heat during charging, so the watts shown are a little lower than the charger's rating. This is normal.
- The estimated time to full is a simple calculation for charging with the screen off. Using the phone while charging takes longer, and charging slows down above 80%, so the real time may be longer.
- On some devices the current or power can't be read, and the app may not show it. The numbers are a guide and not a replacement for a precision meter.
- On some phones (for example Xiaomi), battery-saving features can remove the notification. If that happens, allow auto-start for this app and set its battery usage to "No restrictions".

HOW TO USE
Open the app, allow notifications, and plug in your charger.
