About TCL 20 5G
The TCL 20 5G presents a spacious 6.67‑inch IPS TFT LCD screen that delivers Full HD+ resolution at 1080 by 2400 pixels, offering clear visuals for everyday use. Encased in a chassis measuring 76.8 mm wide, 166.2 mm tall and just 9.1 mm thick, the device weighs 206 grams, striking a balance between a large display and a manageable hand feel. This particular variant carries 128 GB of internal storage and is marketed as a 5G‑ready model, supporting UW TD‑LTE bands for US networks.
Powering the phone is Google Android 10, paired with 6 GB of RAM to handle multitasking and app performance. A 4 500 mAh battery sits inside, aiming to provide enough endurance for a full day of typical usage. Connectivity is handled through a single SIM slot, while the phone retains the essential 5G capabilities highlighted in its name.
This variant steps up the internal storage to 256 GB, twice the amount found in the base model. It is configured for global TD‑LTE connectivity, differing from the UW TD‑LTE band support aimed at US networks in the base version. Compared with the other 128 GB global sibling, it delivers double the storage while retaining the same core hardware and software platform.
