As such, you shouldn't have any problems using it even for long periods of time.

The size and weight of the HTC TOUCH DIAMOND S21HT make it very comfortable to use. If you're looking for a smartphone that is easy to handle and carry around, then this should be your first choice.

HTC TOUCH DIAMOND S21HT's screen

The HTC TOUCH DIAMOND S21HT has a 2.8 inch screen.The screen is rather small, and the displayed text will appear tiny, as will buttons, which most users will feel to be inconvenient and hard to press.

The resolution of the HTC TOUCH DIAMOND S21HT's screen is pretty much standard. It shouldn't be a problem for normal use, but it might prove to be a bit dissatisfying for those who wish to better enjoy their photos, videos, or games.

The camera function of HTC TOUCH DIAMOND S21HT

The main camera of the HTC TOUCH DIAMOND S21HT is 3.2 MP pixels, which is a very low resolution. If you aren't particular about your photos and videos, or rarely ever shoot or film with your smartphone, it should be no problem. But otherwise, you should choose a smartphone at least one tier higher.

The HTC TOUCH DIAMOND S21HT comes equipped with a 0.3 MP pixel front-facing camera, which is very low resolution. If you aren't particular about your videos or photos, it might be fine, but otherwise, we recommend a smartphone at least one tier higher.

The battery performance of HTC TOUCH DIAMOND S21HT

The HTC TOUCH DIAMOND S21HT's battery has a capacity of 900.0mAh, which is rather low.Compared to other smartphones, the HTC TOUCH DIAMOND S21HT's battery does not last very long. As such, while it may prove to be adequate if you don't use it much, or are in a location where you can recharge it, in general, you should have a mobile battery available.

Overall assessment of HTC TOUCH DIAMOND S21HT

The HTC TOUCH DIAMOND S21HT's performance level is that of a budget smartphone. It's a bit too weak to use as a main smartphone, so if possible you should consider something slightly more powerful. However, it should be sufficient for people that only want to use the most basic functions, like making calls and browsing the internet, and for people that don't really use smartphones much.
