Buying advice for Algeria
Both vivo iQOO 15 Ultra and vivo X300 are sold in Algeria, but they fit different priorities.
vivo X300 is 6% cheaper at 192,000 DZD versus 204,000 DZD for the vivo iQOO 15 Ultra, 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.
vivo X300 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.
