Created date: 02/24/2018, 23:01:16, Updated date: 04/03/2020, 07:07:01

We've conducted a detailed review of the Touch Diamond S21HT, looking into its battery, how easy it is to use the camera, and whether the CPU performance is high or low. Not only that, but we've also evaluated how portable and easy to hold it is, as well as how nice the display is.

Features, Performance, and Reviews for the Touch Diamond S21HT

Touch Diamond S21HT's size

The Touch Diamond S21HT is 2.0 inches (51 mm) wide, 4.0 inches (102 mm) tall, and 0.4 inches (11.4 mm) thick. It's extremely compact, and can be easily operated with one hand. In the case of the Touch Diamond S21HT, it weighs about 98 oz (98 g). The weight of this phone is such that you'll barely notice it at all even when using one-handed. As such, you shouldn't have any problems using it even for long periods of time.

The size and weight of the 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.

Touch Diamond S21HT's screen

The 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 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 CPU performance of Touch Diamond S21HT

The processing performance of the Touch Diamond S21HT is quite low at 0.5GHz×1(Single core), and you may find minor issues even while browsing the internet or Twitter.

The Touch Diamond S21HT only has 204.8MB of RAM, which is fairly low. The RAM is regularly insufficient, so operation gets unstable and jerky even when using apps that are not resource intensive.

In rating the Touch Diamond S21HT's overall operational speed, it ranks at the low end of smartphones. It will lag and feel sluggish even during normal use. In most cases, users will feel the performance to be lacking.

Touch Diamond S21HT's storage capacity

The Touch Diamond S21HT has 307.2MB of data storage. This is fine if you mainly use email or social media sites, but if you plan to take photos and videos or play games, you should buy an upgrade.

The Touch Diamond S21HT is not compatible with SD cards, so make sure you check that there's enough storage for your needs.

The camera function of Touch Diamond S21HT

The main camera of the 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 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 Touch Diamond S21HT

The Touch Diamond S21HT's battery has a capacity of 900 mAh, which is rather low. Compared to other smartphones, the 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 Touch Diamond S21HT

The 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.
