I'm not the first to admit that I can't stop eyeing the HTC One X - as an award-winner from Mobile World Congress 2012, just about everyone expects its sales to go through the roof. Justifiably so, considering the specs behind this behemoth of a phone.

But, there is a catch: the battery. Most phones nowadays make use of removable/replaceable batteries, which is handy when we feel like carrying spares, or when the battery is just old and needs to be replaced. HTC's high-end smartphone, however, has a built-in battery.

What does this mean for users? Well, no more resetting a freezing phone by removing the battery (but that's not so bad). Also, you may need to contact a specialist in case your battery ever stops working (or replace it yourself by removing the back-casing, but that isn't recommended, of course). Current reports indicate that the One X's 1800mAh battery doesn't last too long, which might be expected given the powerful processor and graphics the phone provides.

And since you can't (easily) replace the battery yourself, you might as well carry around a high-quality charger whenever possible!
