Bought a 6ft microUSB cord from Fry's. At first it could barely turn my phone on from dead charge, took a day to get it to charge up. Connection is bad, have to have it positioned a certain way, but this has gotten better partially on its own (seems to be getting broken in) and with me getting used to it. I've been charging it with the methods listed at the top (least with official charger, i only was able to use a friend's during the ski trip). It has been sporadic, especially with the car inverter (which i used to charge my old 2005 samsung with a Li-ion battery that expanded). Sometimes it will get a quick charge that ends up being fake and dies really fast. In all charge setups with 6ft microUSB cord charging is slow. Battery life had been pretty normal tho up until the ski trip. I'm kind've confused about phone battery life and going to the mountains to ski. I've read about it a bit and have heard that the cold causes it to die off, but I have a feeling that it has something to do with all the signals at a ski resort. Tons of people with their cell phones, probably only one cell phone tower nearby, high powered walky talkies used by the employees. This must have something to do with the quick drain. My only theory with this long charge is that maybe charging it in cold conditions helped it store extra charge? Anyways, pretty impressive in the end. Looks like this charge will take me til past lunch, maybe even the end of a second work day.
