durability
IP68/IP69K, drop-proof to 1.5mRated for full submersion to 1.5 meters for 30 minutes and certified MIL-STD-810G, so it handles drops, dust, and water you'd need a case to protect most phones from.
battery
5580mAh, roughly 5 to 6 days light useAt this capacity with a 2.0 GHz octa-core and modest 720p IPS display, you get around 1.5 to 2 days of mixed use, or easily 5-6 days if you stay off the screen most of the time.
display
5.7", 282 ppi, IPS LCDAt 282 pixels per inch, individual pixels remain visible if you hold it close; legibility is adequate for email and messaging in indoor light, but outdoor sun will wash it out.
performance
Helio P22, 2.0 GHz Cortex-A53This 2020-era ARM chip handles calls, texts, light browsing, and video streaming; heavy games or rapid app-switching will stall noticeably.
camera
13MP main, 1080p@30fps videoThe f/2.2 aperture and autofocus handle daylight shots and basic video, but low-light photos will be soft and noisy, and you cannot zoom without severe blur.
