I have a Nokia back-up phone. Odd battery problems. Troubleshooting them now. I’m trying to determine if the battery itself is bad. Symptoms are that it will, at any stage less than a full charge, automatically terminate calls after about 15 seconds, and shut itself down. Sometimes the phone displays a “low battery” message just before it shuts down. However, I can turn the phone back on, and it has enough battery power to stay on again for hours. However, if I make or receive another call, the same 15 limit thing happens.
Two questions please:
Is it normal for cell phone batteries, near the end of their charge, to have enough power for extended “on” time, but not enough power to sustain a phone call?
I have never experienced a cell phone shutting itself down due to a low charge, unless it was totally out of power, in which case, it could not be powered up again without charging. Is this auto-shut off thing ever normal?
