battery

10300mAh, roughly 1.5–2 daysAt 10,300 mAh with an efficient low-power chipset, you can expect about 1.5 to 2 days of mixed use before needing a charge.

charging

18W wired, around 60–90 minutesThe 18W charger fills the 10,300 mAh cell from zero to full in roughly 60 to 90 minutes; reverse charging lets you top up another phone from this one.

display

6.6-inch 90Hz LCD, 267 ppiThe 720×1612 IPS LCD runs at 90Hz for smooth scrolling, but at 267 ppi pixel density and Mohs 6 glass (scratch-prone), it trades brightness and clarity for durability on a budget.

performance

Unisoc T7250, light apps and videoThe dual-core Cortex-A75 and Mali-G57 GPU handle messaging, web browsing, and video playback, but not demanding mobile games or heavy multitasking.

camera

50MP main, 1080p video onlyThe 50 MP sensor with f/1.8 and autofocus captures decent daylight stills, but records at 1080p@30fps, so expect soft video and no 4K option.

durability

IP68/IP69K, MIL-STD-810H testedDust-tight and waterproof to 1.5 m for 30 minutes, plus military-grade impact/temperature certification; it survives drops and harsh field use that would wreck most phones.

connectivity

LTE only, no 5G supportWorks on 4G (19 bands), GPS, NFC, and Wi-Fi 5, but lacks 5G, so data speeds cap out at LTE levels—fine for calls and browsing, slow for large downloads.
