display

120Hz AMOLED, 1200-nit peak brightnessAt 1200 nits peak and 120Hz refresh, the screen stays legible in bright sunlight and scrolling through apps feels fluid, though it drops to 60Hz at full QHD resolution to save battery.

performance

Snapdragon 855+, 6GB RAM, Adreno 640This chipset from 2019 handles everyday apps, messaging, and video smoothly, but newer mid-range phones now outpace it for demanding games or heavy multitasking.

camera

64MP main, 0.8µm, f/1.8, optical stabilizationThe 64MP sensor with OIS captures sharp daytime photos and holds steady in dim light; the 12MP ultrawide covers group shots and landscapes, though the 5MP macro is a novelty.

battery

4500 mAh, about 1 day mixed useExpect roughly 5 to 7 hours of screen-on time depending on whether you keep 120Hz on; moderate to heavy use will eat most of a day before needing a charge.

charging

25W wired, roughly 50 to 70 minutesFrom empty, 25W will top the 4500 mAh battery in about an hour; acceptable for a 2021 phone, though slower than the fast charging standard many competitors now offer.

storage

128GB with dedicated microSD slotThe 128GB internal storage is tight for apps, photos, and video, but the dedicated microSD slot lets you expand without losing your SIM.

connectivity

5G Sub-6, Wi-Fi 5, Bluetooth 5.0, NFC5G support covers most urban coverage; Wi-Fi 5 and Bluetooth 5.0 handle wireless devices reliably, and NFC works for contactless payments where available.
