Charge Control: Battery Limit

Stop charging at 80% (or any limit you choose) to reduce battery wear. Charge Control works on rooted Android phones, and now without root too, by switching a smart plug. Lithium batteries age fastest when they sit at full charge and stay hot. Charge Control stops charging at your upper limit and resumes at your lower limit, automatically, even when the app is closed. ★ NEW: SMART PLUG MODE, NO ROOT NEEDED No root? Plug your charger into a smart plug and Charge Control switches it off at your limit and back on when the battery drops. • TP-Link Kasa: found automatically on your Wi-Fi network • Govee: connected with your own Govee API key • Any other plug or automation (Home Assistant, Tuya / Smart Life bridges and more) via simple on/off web links • Heat protection: the plug switches off when the battery gets too hot • Verify step tests your plug before you rely on it • A status notification shows what the plug is doing, with a one-tap "Charge now" • If the plug can't be reached, Charge Control keeps trying to switch it back on, so your phone isn't left without power ★ NEW: CHARGE SCHEDULES Charge differently at different times. Keep 80% during the day and allow a full charge before your morning alarm, or set a tighter limit on weekends. • Rules by time of day and day of week • Ready-made templates to get started in seconds • Skip a rule or pause schedules when plans change • Notifications when a schedule starts or ends ROOT MODE FEATURES • Kernel-level charge control by a lightweight background service that keeps working after reboot • Limit charging current to reduce heat on compatible devices • Automatic discovery of your phone's charging control, with a safe test before it's used • Manual control-file setup for advanced users FOR EVERYONE • Set custom start and stop charging thresholds • Temperature limit: pause charging when the battery gets too hot and resume once it cools down • Temporarily charge to 100% without changing your normal limit, from the app, the limit notification or a Quick Settings tile • Live charge level, current, voltage, temperature and battery health • Charging trends and estimated real battery capacity • Local history of recent charging sessions • Battery and temperature home-screen widgets • Alerts when charging stops working or needs your attention • Material You, AMOLED black and custom accent colors • Available in 17 languages PRIVACY FIRST Your battery data, charging history and smart plug settings stay on your device. Plug settings and API keys are never backed up or sent to us. Smart plug commands go straight to your plug on your home network, or, for Govee, directly to Govee. Optional device-support reporting is off by default and can be turned off at any time. COMPATIBILITY • Root mode needs a rooted phone. Which features work depends on the charging controls your phone's kernel exposes; charging-speed limits are not available on every device. • Smart plug mode works without root on Android 7.0 and later. It needs a supported plug or a plug you can switch with a web link. Newer Kasa and Tapo plugs that use the KLAP protocol are not supported yet. • Manual control-file setup is for experienced users. Only use paths and values you understand. Core charging features are free. An optional one-time Premium purchase removes ads and supports development.
