I have an unrooted Thunderbolt, with both original and new (Rezound 1620mah) batteries. I use Battery Monitor Widget to track my charging discharging.
BMW graphs and histories show some odd patterns, on both batteries:
When charging between 0% and about 50%, I can pull about 750-850ma. I assume I can't get quite to 1a because my cable is a power/data cable. If I use a power only cable, can I do a lot better?
From about 50% on up, it starts pulling smaller and smaller current, down to about 50-60ma by the time it reaches 70%.
After a little more time, the battery will jump to 100%. Again, this happens on the new battery as well. I don't know if it's a calibration issue, a phone issue or a problem with BMW.
If I restart the phone while charging, generally it will show a huge jump, much like when it jumps to 100%.
When discharging, everything seems normal. But if I restart the phone, many times it will show a huge discharge. I will drop 10% sometimes.
There are other times, when BMW reports a flatline. That is, it is discharging with use, but the percentage charged stays the same for sometimes 30 minutes.
I don't remember having this issue when I first got the phone, 15 months ago.
Do I have to do any kind of calibration? Should I find a new battery tracker?
