Nubia Z70 Ultra

The Nubia Z70 Ultra houses a 6150mAh Si-Carbon Li-Ion cell — one of the largest batteries in the smartphone market. This massive capacity translates to comfortable 2-day usage for moderate users, or a full heavy-use day with screen-on time potentially exceeding 10 hours. Keep in mind that the 6.85" 144Hz display is a significant power consumer — so real-world endurance depends heavily on screen brightness and content type.

Wired charging tops out at 80W (USB Power Delivery) — fast enough that a 20-minute charge during lunch provides meaningful battery boost for the rest of the day. Specifically, 0-50% takes approximately 30 min minutes, with a full charge completing in around 65 min minutes. Wireless charging at 50W adds the convenience of drop-and-charge, making nightstand charging effortless.

The charging ecosystem extends beyond basic fill-ups: reverse wireless charging at YesW for topping up earbuds or a smartwatch; reverse wired charging via USB-C; battery health management (600 charge cycles). The battery health features are particularly noteworthy — they help maintain long-term battery capacity by intelligently managing charge cycles, meaning the Nubia Z70 Ultra should hold its charge capacity better over 2-3 years of ownership.

A charger is included in the box — a welcome inclusion that many flagships have dropped. This means you can achieve the full advertised charging speed out of the box without buying a separate adapter.
