How bCare protects your battery

Four quiet habits your battery will thank you for

A real health score, not a good/bad icon

After 7 days bCare measures your battery’s real capacity and charge cycles, then tells you in plain words what is wearing it down and what to do next.

  • Measured mAh and charge cycles
  • Plain-language reasons, no jargon
  • The one thing to do next

Charge alarms that actually ring

Pick 85%, plug in, walk away. bCare rings at the level you choose, and the Alarm-ready check makes sure Android never silences it.

  • Full, low and temperature alarms
  • Alarm-ready check in four quick steps
  • Voice and vibration, even on silent

Beat the heat before it wears you down

Heat is the biggest cause of battery wear. bCare watches the temperature live and, when it climbs, tells you calmly how to cool it down.

  • Live temperature watch
  • Calm, plain-language warnings
  • Exact steps to cool it fast
