Buying advice for Algeria

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

vivo iQOO 15R is 57% cheaper at 139,200 DZD versus 321,000 DZD for the vivo X300 Ultra, leaving room for accessories or a longer screen-protection plan.

vivo iQOO 15R packs a 7600 mAh battery, which translates to longer screen-on time when you are away from a charger.

vivo X300 Ultra reaches a higher main-sensor resolution at 200 MP, which helps with crops and lower-light photos.

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