Modifying the THL W8 battery

[ahabec]

so.. how's the behavior of the battery?
how much different between the original battery and the replacing battery, especially the uptime

I have still to test it.

By the way, I filed down the battery some more today, and I did reach the point where I just took the contacts off with a soldering iron. This doesn't HAVE to be done but if you decide to do it be very precise and do it in an from-up-to-down motion because if you short two contacts with the solder then the battery will be useless.

so this is not really a real-world test but as you can see, even taking into account the phone was used slightly less after I switched to the THL battery (look at awake and screen on times), this screenshot shows the phone used with original battery (with a tiny spike when I replaced the batteries for a few minutes) and then the THL. I think it's already easily visible that the THL drains much slower. You could ski on the graph of the original battery.
By the way, you can also see in the screenshot in the first half of the graph) how much draining goes down when you turn off wifi (my default is always on unless I know I must save battery).
