battery
5000mAh, roughly 1.5 to 2 daysWith this capacity and the Helio G37's modest power draw, you should see around 1 day of moderate mixed use or 1.5 to 2 days if you keep the 720p screen brightness down and skip heavy gaming.
performance
Helio G37, light gaming onlyThe 8-core MediaTek runs casual titles (Candy Crush, Clash Royale) smoothly at default settings but will struggle with demanding 3D games; expect frame drops in anything graphically intense.
display
720p IPS, 260ppi, 60HzThe 6.74-inch panel is sharp enough for normal reading and video at arm's length, but you will notice a soft image compared to 1080p rivals, and scrolling feels noticeably less smooth than a 90Hz+ screen.
connectivity
LTE bands (2G/3G gone)This phone supports FDD LTE on seven bands (700, 800, 850, 900, 1800, 2100) and TDD LTE (2300, 2500, 2600), which covers most markets; it drops 2G and 3G, so if your carrier has already retired those networks you will be fine.
storage
128GB internal, microSD to 512GBThe 128GB base gives around 100GB usable space after the OS; you can expand via microSD up to 512GB for media and files, though app installs remain on the internal drive.
