Hello, I have just bought a tabtech M010s with Android 2.2 and I have some questions about the battery. Firstly, when I initially charged the device it only took about 1.5 hours rather than 4 as it said it would in the manual, and whenever I look in the settings it always says my battery is at 100%, and also says this on the icon at the top of the desktop as well. Also, when the battery dies (I can't tell when to turn it off because of it always says it's fully charged) and I turn it back on after re-charging, my the date and time are completely wrong, like it's reverted back to factory settings. Does any of this suggest my battery is faulty? It seems to last about 2 hours with wifi on and a bit longer without, which is what I was expecting, but I'm a bit worried it might be damaged. Thanks.
