I've had my Pre 3 for almost 2 months and this issue just started happening about 5 days ago. I noticed my Pre 3's screen was completely off while on the TouchStone, when I picked it up it was very hot and wouldn't turn on. I pulled the battery out, let it cool down, put the battery back in and it was completely dead and needed to be charged after being on the Touchstone all night. I haven't installed any new patches, some mornings my Pre 3 will be fully charged while being on the Touchstone all night, this morning it was completely drained. Any ideas? Thanks in advance!
