Xiaomi 15 Ultra Sticks to 90W Charging, While OnePlus Ace 5 Pro Steps Up to 100W

The upcoming Xiaomi 15 Ultra and OnePlus Ace 5 Pro have surfaced in new certification leaks, shedding light on their charging capabilities and other key features.

The OnePlus Ace 5 Pro, meanwhile, edges ahead with 100W charging support. OnePlus executive Li Jie Louis recently hinted at its imminent release alongside the Ace 5 series.

The Ace 5 Pro is confirmed to use the Snapdragon 8 Elite chipset, while the standard Ace 5 will house the Snapdragon 8 Gen 3.

Both models are said to include 6,000mAh-rated batteries, with the base variant supporting 80W charging.

Leaked specs also indicate shared features between the two OnePlus models, including flat 1.5K BOE X2 displays, a metal middle frame, and a ceramic body.

Notably, the Ace 5 Pro is positioned as the most affordable Snapdragon 8 Elite-powered smartphone expected in the market soon.

Both Xiaomi and OnePlus seem to be gearing up for competitive launches, each offering their spin on premium hardware for their respective markets.
