So, I use this cheap 4G feature phone, permanently USB tethered to one of my computers, as a 4G modem.
I am wary of the constant charging/discharging that the battery has been going through.
I want to keep it tethered to the computer without the battery.
Tried both,
1. Booting the phone without battery, while USB tethered
2. Removing the battery from booted and working state, while USB tethered.
No luck, with the above two methods.
This particular phone/battery has 3 pins, +ve, -ve and thermistor. I get a reading of around 7K ohms between the thermistor and -ve terminals .
Dug, a little on the software side, and theoretically it might be possible to make this device work without battery with a modified boot.img file. But, that would be a very involved process.
Can't we just hook up a capacitor and a resistor of similar value to the pins of the phone and fool it into thinking that it has a battery?
Please note, I don't need any battery back-up from the phone - it is permanently connected to the computer.
