I have a Samsung Galaxy Discover that worked fairly well until the last week or so. I ran the device down down to 0% - at which point the device shut off. I performed a full recharge and then occasionally recharged it for brief amounts of time (usually getting to 30-40%).
My battery graph ended up looking something like this:
Then earlier today, I performed a full charge to 100%. The device shut off after a few moments and insisted that the battery was at 0%. I plugged it in and the meter now stays at 0%.
I'm not sure if this is relevant, but I discovered that the voltage is being reported as 4195 mV (the so-called 0%). However, a few days earlier, I remember that the phone seemed to think that about 3800 mV was 0%.
Is there a way to "reset" the battery meter? In other words, I need to tell the phone that it actually has a full charge even though it seems to think otherwise.
Update: the battery was eventually replaced with a brand new one and the issue continues to persist - even with the new battery. Interestingly, the battery seems to charge and operate correctly when the battery temperature is above 30° C.
