Editorial report
Unihertz 8849 Tank 4 12 GB / 512 GB / Global technical sheet
The Unihertz 8849 Tank 4 suits buyers seeking a rugged phone with a huge battery and ample storage. Its main trade-off is the body: it weighs 538 g and is 23.9 mm thick, so it is not for anyone prioritizing portability.
Its 6.78-inch AMOLED display combines 429 ppi with a 120Hz refresh rate. Pixel density is better than most phones of its time, although the screen uses only 75% of the front. Performance is better than most, with a MediaTek Dimensity 7300 Ultra, 12GB of RAM and 512GB of UFS 4.0 storage. Storage is expandable as well.
The 11,600 mAh battery is among the largest of its time, and 66W charging is better than most phones of its time. The 50MP main camera uses a 1/1.31″ sensor, larger than most, but its f/1.88 aperture is worse than most and there is no optical stabilization. Connectivity includes 5G, Wi-Fi 6, Bluetooth 5.3, NFC and dual Nano-SIM, while Android 15 and Google Services cover the software basics.
With a 6.6 NeoScore, the Tank 4 is typical overall among phones of its time. It is a focused choice for buyers who value battery capacity, resistance and storage more than a manageable body.
