I've given up on skype for a while already LG L9 Sleep of death(with battery drained) when I had skype. Warranted the device, final solution was not to use skype. On one laptop, skype is using one cpu core to the max. Solution is to use IE as deafult browser(or not use skype) On second laptop, just yesterday lost all its history.
