my usb connector has just broken, I now have an external charger. Is it possible to do a hack like in the first post, by running the positive and negative connection from the external charger, through the phone, directly to the battery. Whilst the phone is still powered on. Saves the need to swap batteries if this could be done. Basically: External charger -> battery positive and battery negative whilst still plugged into phone and powered on. Will need to hack a hole in the back cover and connect a 2mm charger port possibly. Seems very similar to the first post, except i cant see if having that kind of setup negates the need to use the usb charger. OR. Can I completely ditch going via the external charger, and plug a 2mm charger directly to the battery positive and negative?
