GoSolo Read / what it means6 takeaways

battery

4230mAh, roughly 1 day light useWith typical browsing and messages, you'll stretch a full day; heavier use (video, gaming) drops that to half a day between charges.

display

6.5" IPS, 270 ppi, 480 nits720p resolution means visible pixels up close, but 480 nits keeps text readable in bright sunlight and the large screen works for everyday browsing.

performance

Helio P35, 4GB or 6GB RAMEntry-level processor handles messaging, social media, and light apps smoothly; don't expect fast gaming or quick app multitasking with the 4GB model.

camera

12MP main, f/1.8, PDAF, macro dual-camWide f/1.8 aperture and phase-detect focus grab decent daylight shots; the 2MP macro lens is gimmicky, but 1080p video at 30fps covers basic recording.

charging

No fast charging specifiedCharging speed is not listed; expect standard microUSB pace, which is slow by 2020 standards and will take several hours from empty.

connectivity

LTE only, Wi-Fi 5, Bluetooth 5.0No 5G; LTE is adequate for most regions and Wi-Fi 5 (802.11ac) covers home use without lag.
