Buying advice for Algeria

Both Samsung Galaxy S26 Ultra and Xiaomi 15 Ultra are sold in Algeria, but they fit different priorities.

Samsung Galaxy S26 Ultra is 18% cheaper at 270,000 DZD versus 328,800 DZD for the Xiaomi 15 Ultra, leaving room for accessories or a longer screen-protection plan.

Xiaomi 15 Ultra packs a 5410 mAh battery, which translates to longer screen-on time when you are away from a charger.

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