Trickle – Battery Monitor

Trickle shows you what your battery is actually doing, right now, on a single screen. No ads. No interstitials. No tracking. No account. No network access at all. WHAT IT SHOWS • Charge level, and whether you are charging, discharging, full, or being held at a charge limit • Current draw in milliamps, both live and averaged • Power in watts • Voltage • Battery temperature, alongside the thermal state Android itself reports — so you can see when your phone is genuinely throttling instead of guessing from a number • What you are plugged into: AC, USB or wireless • Estimated full capacity and charge cycle count • Time to full, or time to empty, using Android's own predictions rather than dividing two numbers and hoping • A rolling two-minute trace behind the fast-moving readings, so a spike is something you can see rather than something you have to catch BUILT TO STAY OUT OF THE WAY A battery monitor that costs you battery has failed at its job. • Reads once a second, and only while the screen is in front of you • No background service, no wake locks, no scheduled work • Nothing is stored. The graphs live in memory and are gone when you close the app • No permissions to grant • No internet access, so nothing can leave your device even by accident HONEST ABOUT HARDWARE Phones differ in what they are willing to report. Some do not expose a design capacity, so a battery health percentage is not possible. Some do not report energy in watt-hours. Where a reading is not available, Trickle leaves the tile out rather than showing you a number it had to invent. LANGUAGES English, German, French, Spanish, Italian and Portuguese. Temperature follows your locale: Celsius in most of the world, Fahrenheit where that is the norm.
