I think they are set to shut down when the battery reaches roughly 10%, as a safety feature

 

usually it would get to about 5 depending on the phone itself but calibrate your battery using "battery calibration" from the market and see how it goes next time

 

Its pretty normal. I wouldn't worry about to much. Its bad for our batteries to drain completely. So like already stated, its a for the good of the battery

 

Yup, I have the same (non)problem. It's a feature designed to stop the phone shutting off immediately and potentially doing some damage to itself.

Sort of like if you yoinked the power cable out of the back of your pc while it was on, It wouldn't be pretty

 

Recently there was a thread bout this exact 'feature'...needless to say some people are a little miffed about it lol

personally I don't care....I get about as much battery life as I expect from a smartphone with large colourful touchescreen with always on connectivity etc..

yea....wasn't pretty the other day when I tripped on my laptop power cabled....I didn't pull the laptop off a table or anything...but the sudden jolt somehow un-seated either the memory or hard drive...and I had headaches for a while taking apart the machine and re-fitting everything lol
