GoSolo Read / what it means7 takeaways

display

6.4", 1080×2400, 411 ppiThe 411 ppi density and Super AMOLED panel keep text sharp and colors punchy, but this is a 2020 model without the 90Hz+ refresh rates now standard at this price, so scrolling and gaming will feel noticeably less smooth than newer budget phones.

battery

5000 mAh, about 1 day heavy useWith typical mixed use (browsing, messages, apps) you'll reach evening comfortably; heavy video playback or gaming will drain it to zero in around 6 to 7 hours of continuous screen time.

charging

15W wired, roughly 90 to 120 minutes15W is slow by today's standards; expect about 1.5 to 2 hours to go from zero to full, which means this phone does not support quick top-ups.

camera

48MP main, 8MP ultrawide, 5MP macroThe 48MP sensor captures fine detail in daylight, the 123-degree ultrawide fits group shots and landscapes into one frame, and the 5MP macro lets you close in on small objects, but the 1080p video at 30fps is dated and the lack of telephoto limits distant subjects.

performance

Helio P65, Mali-G52 MC2, 4–8 GB RAMThis chipset from 2020 handles everyday apps and light gaming (turn-based, casual mobile titles) smoothly, but cannot run modern high-end games at playable frame rates or handle intensive multitasking without lag.

connectivity

LTE, Wi-Fi 5, Bluetooth 5.0, NFCLTE is still sufficient for web, streaming, and messaging in most regions; Wi-Fi 5 and Bluetooth 5.0 are solid for their era, and NFC (where available) handles contactless payment.

durability

Optical fingerprint, no water ratingThe under-display optical fingerprint sensor works but is slower than modern capacitive versions; no IP rating means the phone is not rated for dust or water resistance, so avoid splashes and wet pockets.
