Performance:

Call quality on both handsets isn't going to give you any trouble, with loud and clean voices in the earpiece, and well-filtered background noise when you are talking, thanks to the noise-canceling mics. As mentioned, the loudspeaker is more powerful on the One X, so you are less likely to miss a call with it than with the One S.

In our usage of the HTC One X and One S we didn't notice any unusual drain of the batteries. The 1800mAh one on the flagship and the 1650mAh of the One S will get you through a day with average usage on automatic brightness, but don't expect any miracles without leaving the phones on GSM, using the other radios only when needed, and restricting screen usage, especially in the case of the huge LCD one. 

The display technologies also play a role here – if you are watching movies, you'll get about eight hours mileage from the One S with its AMOLED display and the usual six from the One X. If intensive browsing is involved, though, expect it to tire much faster than the One X, which doesn't consume more energy when displaying white backgrounds as the One S does. In everyday scenarios the mixed usage about evens out the battery stamina of both handsets.


Conclusion:

In line with the intent to simplify its phone portfolio, HTC has made the One series trio pretty distinct from each other, and the final verdict in our One X vs One S comparison is very easy. 

If you are a sucker for large and brilliant HD screens, you won't be bothered by the HTC One X's dimensions or the about 100 bucks (or euros) price premium, and grab it without second thoughts. It's light and comes with 32GB of memory to soothe your non-expandable storage pains.

If you are any other type of smartphone shopper, though, and that's the vast majority of people, we'd recommend you stick with the HTC One S – it is stunningly compact for a 4.3-incher, making one-handed operation easier, and also has a premium feel in the hand thanks to its thin ceramic metal or anodized aluminum chassis. You'll have to make do with 16GB of internal memory, but if you are eying any of those two, you are likely not bothered by their lack of memory card slots and non-removable batteries anyway.
