精准电量「Accubattery」Pro 是一款非常好用的电池健康检测维护管理软件，其基于一系列科学的研究和测试「信息数据量都很大，这里就不详解了，我不会告诉你是我解不了！」，能测试出设备电池的实际容量，并查看电池损耗，而且还可以通过设置充电到达百分数「Accubattery 建议是80%」提醒拔掉充电器，实现保护充电增加电池循环寿命，从而让您的电池保持健康。

AccuBattery 官方宣称只将手机电池最多充至80%能将电池寿命延长到200%哦！是是不是很有诱惑力！别拉我！反正我是要上车了！不仅如此，精准电量「Accubattery」Pro 还有检测电池寿命、充放电速度、温度、电压等众多的功能。

Accu​Battery protects battery health, displays battery usage information, and measures battery capacity (mAh) based on science.

Battery health

Batteries have a limited lifespan. Every time you charge your device, it wears out the battery, lowering its total capacity. Scientific research shows that battery lifespan can be extended up to 200%, when you charge your device to only 80%.

- Use our charge alarm to prolong your battery lifespan.
- Discover how much battery wear was endured during your charge session.

Battery use

Accu​Battery measures the actual battery usage using information from the battery charge controller. Battery usage per app is determined by combining these measurements with information on which app is in the foreground. Android calculates battery usage using pre-baked profiles that device manufacturers provide, like how much power the CPU uses. In practice however, these numbers tend to be highly inaccurate.

- Monitor how much battery your device is using
- Know how long you can use your device when it’s active or in standby mode
- Find out how much power each app uses.
- Check how often your device gets woken up from deep sleep.

Charge speed

Use Accu​Battery to find the fastest charger and USB cable for your device. Measure the charging current (in mA) to find out!

- Check how fast your device is charging when the screen is on or off.
- Know how long it takes to charge your phone and when it’s finished.

Highlights
- Measure real battery capacity (in mAh).
- Use the charge alarm to prolong battery lifespan.
- See how much wear your battery sustains with each charge session.
- Look up the discharge speed and battery consumption per app.
- Remaining charge time - know how long it takes before your battery is charged.
- Remaining use time - know when you will run out of battery.
- Screen on or screen off estimations.
- Check the percentage of deep sleep, when the device is in standby mode.
- Ongoing notification for real time battery statistics at a glance.
