Cooldown overview: the battery is at 30.9°C, status Normal, with Low-temperature mode and heat alerts turned on

How hot is too hot?

Phones warm up when they charge, stream or run games, and some warmth is normal. Cooldown puts every battery reading on one scale, and alerts you when it reaches your alert threshold, 42°C by default.

A battery temperature scale from 30 to 50°C, divided into Cooldown's four levels: Normal, Warm, Overheated and Critical. A reading of 42.3°C falls in Overheated.

No fake cooling.

  • It doesn't claim to cool your phone instantly.
  • It doesn't force-stop apps or lock CPU and GPU speeds.
  • It doesn't need root or read private system files.

Cooldown shows what is really heating your phone, and how to cool it down safely. Readings come from Android itself, so the available sensors vary by device.

Monitoring and alerts are free.

Pro is a one-time purchase, not a subscription. It removes ads and adds temperature insights, detailed heat-risk signals, a custom alert threshold, color themes and transparent widgets.
