About this app
BattWatch keeps an eye on your battery so you don't have to — accurate health, honest numbers, and alerts that actually help.

• Optional vibration, custom sounds, silent-mode override
★ Real battery health
• Estimated battery health % and wear grade
• Charge cycle count (uses the OS value on Android 14+)

• Days-in-use tracking
★ Charging intelligence
• Live charging speed — tier and wattage (e.g. "Fast charging ~18 W")
• Estimated time to full
• Slow-charge warning for a frayed cable, dirty port, or dying charger
★ Live status
• Ongoing notification: %, charging state, temperature, charge/drain rate
• High-temperature safety alert
• Fast-drain alert when something drains your battery in the background
