Very simple "1%" One Percent Battery Hack!

Hi Folks,
I'm not sure whether this is the right place, but I just wanted to share this information:
There is a very simple way of forcing all Apks of a rooted Defy with init.d support to read battery stats with 1% accuracy. Just add this script in /system/etc/init.d/ and name it something like '12onepercentbattery':
Code:
#!/system/bin/sh
# fake access to 10% battery status to 1%
busybox mount -o bind /sys/class/power_supply/battery/charge_counter /sys/class/power_supply/battery/capacity
I basically tested this on a 4.5.1-134_DFP-74 modded by Greenbreadmod_1.1 on a green lensed Defy.
Explanation: in sysfs /sys/class/power_supply/battery directory the kernel provides a 1% charge counter by the file 'charge_counter', but the Android framework only reads 'capacity' which only has 10% accuracy.
The script establishes a file system redirection from 'capacity' to 'charge_counter', so all Android apks will read the more accurate charge counter instead
Hope this helps someone out there...
