Buying advice for Algeria

Both Xiaomi 17 Ultra and Xiaomi 18 Pro Max are sold in Algeria, but they fit different priorities.

Xiaomi 17 Ultra is 13% cheaper at 239,000 DZD versus 275,000 DZD for the Xiaomi 18 Pro Max, leaving room for accessories or a longer screen-protection plan.

Xiaomi 18 Pro Max packs a 8500 mAh battery, which translates to longer screen-on time when you are away from a charger.

Xiaomi 18 Pro Max posts a stronger benchmark score, useful for heavier games and multitasking on Algerian carriers' busier 4G networks.

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