I also happy with the 10 hours continue playing, but the issue in battery is a big issue and affect the normal state of x1. Im also done with last test (Fully charged x1 without using for almost 20 hours - then turn on again but the battery bars now is 3) not normal right?? Btw anyone can give information about standby time for x1... Thanks
No that doesn't sound normal. The battery isn't holding it's charge like it should.
