Battery Guard

Protect your battery and extend the cycle life.

Experiments on lithium batteries have proven that shallow charging and discharging maximizes the cycle life of the battery, if the loss of charge from 0% to 100% is recorded as 1 cycle, then

* Charge to 90%, only 0.52 cycle

* Charge to 80%, only 0.27 cycle

Battery Guard can set high and low thresholds and then alerting the user when the power reaches the threshold, so that the battery maintains a shallow cycle working state.

App features are as follows:

* Light and compact App, less than 200k.

* Support text, vibration and voice alarm when the power reaches the threshold.

* Voice alarm uses TTS engine and supports custom voice.

* Backend records daily battery cycle loss and generates daily, weekly and monthly statistical charts.

* Record battery temperature and generate daily, weekly and monthly statistical charts.

* Record daily bright screen time and generate daily, weekly, and monthly statistical charts.

* Support charging and discharging details, including charts of power, temperature, current, etc.

In addition to the basic battery-related statistics, the following functions are supported.

* Support daily, weekly, and monthly screen time statistics.
