GoSolo Read / what it means5 takeaways

battery

9600 mAh, roughly 2 days moderate useA large battery that stretched across a 6.58-inch screen at 120Hz should keep you off the charger for a full day and into the next if you mix light and medium tasks.

performance

MediaTek Helio G99, indie and light gamingThe 8-core 2.2 GHz chipset handles everyday apps and older or lighter titles, but will struggle with heavy modern games at high settings.

display

120Hz, 6.58-inch, 1080p IPSA tall 401-ppi screen with 120Hz refresh makes scrolling smooth, but at 1080p density you may spot pixels in bright light up close.

durability

IP68 and IP69K, full submersion and jetsBoth IP68 and IP69K ratings mean this phone survives full immersion in water and high-pressure jets, a rare dual-rating for fieldwork in wet environments.

storage

256 GB internal, microSD up to 2 TBThe internal storage is fixed, but a microSD slot lets you expand well beyond typical phone storage if you load photos, videos, or files for offline use.
