How does the android system check the status of the battery.
I'm learning to create a queue application where the display queue at the service counter uses a locally made android tablet known as Advan t2h (usually service counter using seven segments).
Because micro usb slot is used for otg (wireless numeric keypad) so there is no slot to charge the tablet. For that matter I use additional external component (tp4056 ic with circuit) which is connected directly to tablet battery.
Status in circuit tp4056 indicates that batre is in charge condition. Only on the android system, battery status continues to decline with the same time when only using batteries without additional circuit tp4056.
So what I want to understand here is
1. How android system check the status of batre.
2. when the battery status live 15%, the system raises the warning, and the warning is certainly disturbing because it blocks the display. So how to disable the warning.
3. when the battery status of the remaining 7%, the system automatically turn off the device, and must be restarted after a while. When the device is restarted, the battery status is full again, or at least 80%, so what is the previous battery down status until the dead device is a timer only?
