battery
1000mAh, roughly 2-3 days idleAt this capacity with a low-power single-core processor and tiny 1.77-inch screen, you'll stretch a charge across several days if you use it only for calls and texts, but heavy texting or FM radio will drain it faster.
display
1.77-inch TFT, 128x160 pixelsThis is a basic monochrome-era screen; you'll read text and see call logs clearly enough, but color reproduction and brightness are not adequate for web browsing or photo viewing.
performance
312 MHz single-core, calls onlyThe MT6261D and 312 MHz CPU are designed for voice and SMS only; any attempt to run apps or access the web will be unusable.
connectivity
GSM 2G only, no 3G/4G/5GThis phone works only on old GSM networks; in many countries those networks are being shut down, so check if your carrier still supports 2G before buying.
camera
0.3MP VGA, still frames onlyThe VGA sensor can capture blurry snapshots and basic video, but resolution is too low for any use beyond proof-of-concept documentation.
