Buying advice for Algeria

Both vivo iQOO 15 Ultra and vivo X300 FE are sold in Algeria, but they fit different priorities.

vivo iQOO 15 Ultra is 16% cheaper at 204,000 DZD versus 244,000 DZD for the vivo X300 FE, leaving room for accessories or a longer screen-protection plan.

vivo iQOO 15 Ultra packs a 7400 mAh battery, which translates to longer screen-on time when you are away from a charger.

vivo iQOO 15 Ultra posts a stronger benchmark score, useful for heavier games and multitasking on Algerian carriers' busier 4G networks.

Above 100,000 DZD you are paying for the chipset, camera tuning, and long-term software support, so weigh those against price.
