Phone Temperature Monitor

Phone Temperature shows your phone's REAL battery temperature — live, read straight from Android's own battery and thermal sensors. Every number on screen is a genuine sensor reading. Nothing is estimated, guessed, or faked.

Here's the honest part most apps won't tell you: no app can physically cool your phone. The popular "cooler" and "cooling master" apps that promise a one-tap temperature drop are selling you a number, not a result — software can't lower hardware heat. Phone Temperature is built on the opposite promise. We never claim to cool your phone. We show you the real, live reading, log it over time, and warn you when it climbs — so YOU can act.

WHAT YOU GET
• Live battery temperature in °C or °F, read from your phone's own sensors
• System thermal status — normal, light, moderate, or severe throttling — where Android exposes it
• Thermal headroom: how close your phone is to throttling, on devices and Android versions that report it
• Charging state and battery level at a glance
• Temperature history with an interactive chart, selectable windows from 1 hour to 30 days, plus min, max, and average
• Export your full history to CSV whenever you choose
• Optional overheat alerts using your own temperature and/or thermal-status thresholds
• Optional background logging through a foreground service with a clear, permanent ongoing notification — never hidden
• A plain-language Learn guide on why phones get hot and how to actually bring the heat down: take off the case, get it out of direct sun, stop charging or heavy use, and let it rest

HONEST BY DESIGN
• Every value is a live reading from a real Android API — never an estimate
• If your device doesn't expose a sensor, we say "not available on this device" instead of inventing a number
• We never claim to cool, boost, or optimize your phone, because no app can
• Your temperature history and settings stay ON YOUR DEVICE — the only thing that leaves is a CSV you choose to export
• Works offline; no account required
• Anonymous, opt-in analytics and crash reporting help us fix bugs and NEVER include your temperature readings
• Minimal permissions: no location, no contacts, no SMS, no body sensors

Whether you're watching a phone that runs hot while gaming, navigating, or fast charging, checking battery health on a warm day, or just want an accurate, real-time battery temperature monitor you can trust, Phone Temperature gives you the truth and nothing extra.
