The Alcatel Idol 4S packs an impressive punch, thanks to its hefty array of hardware internals, sleek modern design, and great overall value. The versatile smartphone has a 5.5” FHD AMOLED display that’s bright even in direct sunlight, plus a 16MP main camera capable of shooting video in 4K at 30fps alongside an 8MP selfie camera that can handle capturing video in 1080p at 30fps. The phone packs a substantial 3,000mAh battery, a modest amount of internal storage (with a dual-sim/microSDXC slot you can use to add more), and dual 3.6-watt JBL-certified speakers with Hi-Fi audio that’s loud and clear.
