performance

Exynos 7884B, 1.6 GHz 8-coreThis older mid-range chip (from 2020) handles everyday apps and light games, but struggles with heavy multitasking or demanding titles.

battery

3600 mAh, about 5-6 hours screen-onWith light use you may stretch a full day, but heavy browsing or video will require a midday charge.

display

5.8" IPS, 720p, 60 HzThe 296 ppi density is sharp enough for reading text, but the 720p resolution and 60 Hz refresh feel basic by 2024 standards and text rendering is less crisp than 1080p panels.

durability

IP65, IP68 water and dust protectionThe phone survives dust and water immersion up to 1.5 meters for 30 minutes, so light splashes or brief dunking is safe.

storage

64 GB internal, expandable via microSD64 GB leaves you roughly 40–45 GB usable after the OS; add a microSD card (up to 2 TB) to store photos, videos, and apps without filling the phone.
