Comment(by lindi):

 I found a crude workaround: If battery capacity is less than 95% and the
 battery is in state "Not charging" I switch to usb host mode and back to
 device mode. After that battery switches back to "Charging" state and you
 should always have a full battery if you have left the phone to charge
 over night. My script to do this is very ugly but I thought I should
 mention it here anyway:

 {{{
 #!/bin/sh
 set -e

 dir="/sys/devices/platform/bq27000-battery.0/power_supply/bat"
 if [ ! -d $dir ]; then
     dir="/sys/class/power_supply/battery"
 fi

 while true; do
     echo -n "`date -Iseconds` `date +%s`"
     for i in type status voltage_now current_now charge_full temp
 technology present time_to_empty_now time_to_full_now capacity online; do
         val="`cat $dir/$i | sed 's/ /_/'`"
         echo -n " $val"
     done
     val="`cut -d' ' -f2 /proc/loadavg`"
     echo -n " $val"
     echo ""
     if [ "`cat $dir/capacity`" -lt 95 ]; then
         if [ "`cat $dir/status`" = "Not charging" ]; then
             usbhost-start
             usbhost-stop
         fi
     fi
     sleep 120
 done
 }}}
