In addition, the battery charges slower at around 80%, so the app also saves time!
Other features that do not require root:
- Creation of a charging curve, so you can see how the battery was charged and how warm it was during the process.
- History of past charging cycles and automatic saving of graphs
- A battery info notification with the current state of the battery
- A dark theme/design -> optional for the info notification!
- The warnings are individually switchable for different charging methods (normal, USB or wireless charging).
Additionally, the app has the following features that require root:
- Automatic charging cancellation, so you don't have to be near to hear the warning tone.
This doesn't work with all devices! I have to customize the app for the device.
- Smart Charging - regulates charging for longer charging sessions (e.g. overnight) to conserve the battery as much as possible.
This assumes that "charging cancellation" works on your device!
- USB charging deactivation
This prevents the device from charging when it is connected to a PC/Mac via USB.
This also assumes that "charging cancellation" works on your device!
- Automatic resetting of the Android internal battery statistics as soon as the battery high warning appears
- Activation of energy saving mode as soon as the battery low warning appears
