<font size=2 face="sans-serif">Hello,</font>
<br>
<br><font size=2 face="sans-serif">I made some further tests with Qtmoko
v52 and found that it's not necessary to "calibrate" the battery
by stressing it through needless discharging/recharging cycles. In order
to get a working battery indicator again, it's sufficient to use Qtmoko
v52 together with the 3.2 kernel from Qtmoko v47. It works well, except
that the modem will not be recognized. But you can play games like QtMaze
for example.</font>
<br>
<br><font size=2 face="sans-serif">So simply set up your SD card in a way,
that you use the scripts 1.sh and 2.sh for toggling between former 3.2
and current 3.7 kernel. This allows you to decide with only one touch during
boot if you wanna see a working battery indicator or if you wanna have
a working phone. This should work fine until the broken driver within the
kernel had been repaired.</font>

<br><tt><font size=3>That's also consistent with my experience. FWIW
what I experienced was<br>
that my previously happy and relatively new battery somehow lost its<br>
calibration. Then I charged it as much as I could, and then ran the<br>
battery down as fast and quickly as I could, all the time with the<br>
battery page of QtMoko's NeoControl application open. What I saw
was<br>
that the calibration came back - i.e. the 'charge_full' value - when the<br>
'charge_now' value was going down linearly and within a minute of<br>
hitting zero.<br>
