Buying advice for Algeria
Both vivo iQOO 15 Ultra and vivo X300 Pro are sold in Algeria, but they fit different priorities.
Both phones sit in the same price band, so the choice comes down to specs and brand preference.
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 Pro 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.
