Charge Control: Battery Limit

Stop charging at 80% (or any limit you choose) to reduce battery wear. Charge Control works three ways: with root, with your phone's own built-in charge limit (no root), or 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: BUILT-IN LIMIT, NO ROOT NEEDED

Many phones have their own battery protection. Charge Control switches it on, picks the level, and puts your original setting back when you turn it off.

• Samsung (One UI 4, 5, 8 and 9), Pixel 6a and newer (Android 15+), OnePlus, Oppo and Realme (ColorOS 15), Nothing OS 4

• The phone enforces the limit itself, so it keeps working when the app is closed

• One-time permission with Shizuku, a computer (adb) or root

★ NEW IN 4.4

• Profiles: save a charging setup and switch to it in one tap

• Charge once to a chosen level (85, 90, 95 or 100%) without changing your normal limit

• Charge history with charging curves and real battery capacity estimates

• Activity log of every pause, resume and problem

• Automation for Tasker, MacroDroid and adb

• Quick Settings tiles, an on/off widget and an optional status notification

• Back up and restore your settings

SMART PLUG MODE, NO ROOT NEEDED

Charge Control switches your charger's smart plug off at your limit and back on when the battery drops.

• TP-Link Kasa found automatically on your Wi-Fi; Govee 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, a verify step, and a status notification with a one-tap "Charge now"

• If the plug can't be reached, Charge Control keeps trying to switch it back on

CHARGE SCHEDULES

Keep 80% during the day and allow a full charge before your morning alarm, or a tighter limit on weekends.

• Rules by time and day, ready-made templates, and a quick skip or pause when plans change

ROOT MODE FEATURES

• Kernel-level charge control by a lightweight background service that keeps working after reboot

• Automatic discovery of your phone's charging control, with a safe test before it's used

• Switches to a backup control automatically if the first one stops holding your limit

• Pause while gaming: stop charging while a game is open to keep the battery cool

• Don't recharge until unplugged

• Low battery alert and automatic power-off before a deep discharge

• Limit charging current, or charge voltage (beta), on compatible devices

• 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

• Live charge level, current, voltage, temperature, battery health and cycle count

• Battery, temperature and on/off 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. Features depend on the charging controls your kernel exposes; speed and voltage limits aren't available on every device.

• Built-in limit works without root on the phones listed above; the levels you can choose depend on the phone.

• 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.

Core charging features are free. An optional one-time Premium purchase removes ads and supports development.
