durability
IP68/IP69K, MIL-STD-810H ratedSealed against dust and submersible to 1.5 meters for 30 minutes, plus military drop and shock testing, so it survives rough sites, wet conditions, and concrete drops that would kill most phones.
battery
5180 mAh, about 1.5 to 2 daysWith a 2.0 GHz quad-core CPU and 450-nit LCD, expect roughly 1.5 to 2 days of mixed use before the battery runs dry.
charging
10W wired, roughly 2 to 3 hoursA 5180 mAh cell on 10W charging will take about 2 to 3 hours to reach full, so plan accordingly before a long day.
performance
Helio A22, Cortex-A53, light use onlyThe quad-core 2.0 GHz processor and PowerVR GE8320 GPU handle email, messaging, and video playback, but will stall on heavy games and multi-tasking with many open apps.
display
6.1", 450 nits, 282 ppiThe 450-nit IPS LCD is readable in bright sun but not exceptional, and the 720p resolution at 282 ppi is soft up close; fine for text and photos, noticeably pixelated on detailed images.
camera
13MP main, 5MP selfie, 1080p videoThe 13MP sensor with LED flash handles daylight snapshots and group photos adequately, but low-light shots will be noisy and video is capped at 1080p@30fps, so no 4K or slow-motion.
