The no1 criterion of a phone is that it works for the whole day. At least as far as I care. So here is the picture of how the HTC One X failed, on that basis. The x-axis runs the length of a day. I used the phone to watch tv and listen to radio. By 1pm the battery was in dire straits.
So the rest of the day was "plug it in, don't use it" then "use it, but plug it back in when you can".
That's bullshit. I never had this with the iPhone. I won't be held to ransom by a bunch of people who traded "flash" for functionality. My productivity was nobbled from lunchtime.
I don't think the HTC One X is a serious phone.
