Buying advice for Algeria
Both Xiaomi 15 Ultra and Xiaomi Poco X8 Pro Max are sold in Algeria, but they fit different priorities.
Xiaomi Poco X8 Pro Max is 17% cheaper at 121,000 DZD versus 145,000 DZD for the Xiaomi 15 Ultra, leaving room for accessories or a longer screen-protection plan.
Xiaomi Poco X8 Pro Max packs a 8500 mAh battery, which translates to longer screen-on time when you are away from a charger.
Xiaomi 15 Ultra posts a stronger benchmark score, useful for heavier games and multitasking on Algerian carriers' busier 4G networks.
Xiaomi 15 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.
