HTC One review
Android 4.1 (JellyBean), 4.7in 1,920x1,080 display
First impressions are great. The One is a gorgeous phone, and we think it wipes the floor with the Sony Xperia Z. The combination of metal rear, bevelled metal edges and edge-to-edge screen are class itself, and make the Xperia Z feel square and tacky, despite its glass rear. The HTC One's curved back also makes it comfortable to hold - a minor downside is that it's tricky to type when it’s lying flat on a desk.
The metal-backed HTC One is a thing of beauty, and even out-classes the Sony Xperia Z's glass chassis
We were also seriously impressed with the screen. It's a 4.7in model with a Full HD 1,920x1,080 resolution, leading to a huge pixel density figure of 468ppi. When compared side-by-side with the Xperia Z's display, we preferred the HTC One's screen, thanks to its superb contrast. It has incredibly deep blacks (for an LCD at least), and our test photos showed rich, vibrant colours and plenty of shadow detail.
The Xperia Z had the advantage when it came to looking at web pages, however; its slightly larger 5in display meant text was ever-so-slightly larger and easier to read when web pages were fully zoomed out, helped by brilliant white backgrounds, compared to the very slight grey tinge on the HTC One.
Last year it was 720p, now Full HD 1080p screens are becoming the norm on top-end smartphones
This difference was borne out in our subjective web browsing tests. Both phones rendered graphics heavy web pages at a similar speed, but when zoomed in and panning around a web page, the Xperia Z would stutter when coming across a large image – a problem we didn’t have with the HTC One.
Luckily, HTC has provided a huge 2,300mAh battery to power the fast processor and bright screen. The handset managed 8h 32m in our continuous video playback test, which is a strong result and bodes well for all-day battery life.
If we have one major gripe with the HTC One, it's is lack of expandable storage - unless you buy the top-end 64GB model, you could quickly find yourself running out of space if you take a lot of photos and video, or use your handset as an MP3 player.
HTC is preparing to rectify this problem with an updated model which includes a removable rear cover, much like the HTC One Max. Known as the HTC One 802w in China, where it's already on sale, it will simply be called the HTC One Dual SIM here in the UK.
It will still be made of aluminium, rather than plastic like the HTC One Mini, but include a microSD card slot as well as twin SIM card slots.
This is somewhat rare for the UK, as dual SIM handsets typically aren't very popular with customers. They are much more popular in developing nations, but twin SIM card slots could still be a welcome inclusion for anyone that wants to keep work and home life separate without carrying two phones.
If you've been put off by the HTC One's limited storage you may want to wait a little longer - although no release window has been confirmed, you can pre-order the handset for £495 through the HTC Store.
Unfortunately, you have to make a choice between extra storage and faster internet speeds, as the dual-SIM model doesn't support 4G LTE networks. If you live in an area without 4G coverage, however, it could be an easier decision.
