GoSolo Read / what it means6 takeaways

display

6.8", 220 ppi, IPS LCDThe 640 x 1352 resolution (220 ppi) and IPS panel are a step down from budget phones today; text and images will look softer, but outdoor readability is decent for the size.

performance

1.3 GHz quad-core, 2GB RAMThe Mediatek MT6739 and 2GB RAM handle basic tasks (calls, messaging, light browsing) but struggle with heavy apps or multitasking; expect noticeable lag switching between apps.

battery

3500 mAh, about 1 day light useAt this capacity and CPU class, expect roughly 14 to 16 hours of standby or about 5 to 6 hours of continuous screen time before you need to charge.

charging

10W wired, roughly 2 to 3 hoursThe 10W charger will take around 2 to 3 hours to go from empty to full; plan accordingly if you need the phone ready quickly.

camera

13MP main, 8MP selfie, LED flashThe 13MP main sensor with autofocus and LED flash handles daylight shots and basic low-light work; the 8MP front is fine for casual video calls and selfies.

connectivity

LTE Cat4, Wi-Fi 5, Bluetooth 4.0LTE reaches roughly 150/50 Mbps downloads/uploads in good signal; Wi-Fi 5 (802.11n) and older Bluetooth 4.0 will connect without drama but at slower speeds than newer phones.
