Cellsense: Battery Health

Your phone shows a percentage. Cellsense shows how healthy your battery really is and how fast your charger actually charges, without running in the background all day. Most battery monitors keep a service alive around the clock and end up draining the battery they are supposed to watch. Cellsense reads your battery only while you look at it. No background service, no drain from the app itself. CHARGING SPEED TEST • Plug in, wait 30 seconds, see the real watts • Average current (mA) and voltage (mV) from 30 live readings • Slow, Normal or Fast rating for every charger • Name your chargers and cables, then compare them side by side • Unplug mid-test and it starts over, so the number is never a mix BATTERY HEALTH YOU CAN TRUST • Estimated battery capacity in mAh compared with the design capacity • Battery health percentage with the number of readings behind it • Low, Medium or High confidence, so you know how sure the estimate is • No full charge or full drain needed; every app open adds a reading • Capacity trend graph over time LIVE BATTERY STATS • Battery level, temperature, voltage and charging current at a glance • Charging watts while plugged in • Temperature turns yellow at 40°C and red at 45°C HOME SCREEN WIDGET • Battery level, temperature and charging watts • Tap the widget to start a charging speed test right away LIGHT AND PRIVATE • No account, no sign-up • Test results and charger names stay on your phone • Dark and light themes • Optional morning and evening battery check-in reminders Cellsense reads the values Android reports for your battery.
