Oppo has officially raised the bar for battery capacity in mid-range smartphones with the launch of the Oppo A7 Pro Max 5G in China. Debuting as the brand’s first phone to sport a massive 10,000mAh Glacier Battery, Oppo has timed this launch right before Xiaomi unveils its highly anticipated competitor, the Redmi Note 17 Pro Max 5G.
While Redmi prepares for the official launch in China and global markets, the specifications of the global edition of the Redmi Note 17 Pro Max have already leaked via official-looking promo material. The Chinese variant of the Note 17 Pro Max is expected to share identical core specifications with its global counterpart, barring a potentially larger battery capacity for the Chinese market.

Here is a detailed head-to-head comparison between the Oppo A7 Pro Max and the Redmi Note 17 Pro Max to see which battery behemoth offers the better overall package.
6Verdict
The Oppo A7 Pro Max 5G is a targeted engineering achievement for power users who put absolute battery life above all else. With a colossal 10,000mAh silicon-carbon battery squeezed into an 8.57mm body, fast 27W reverse charging, and a solid IP69K build, it stands as an ultimate power station smartphone.
However, looking at the complete hardware package, the upcoming Redmi Note 17 Pro Max 5G delivers a more balanced all-around experience. While its 9,210mAh battery is slightly smaller than Oppo’s, it compensates across almost every performance metric, offering a significantly faster chipset, superior display brightness and eye protection, versatile 4K cameras with an ultra-wide sensor, faster 100W charging, and modern AI software features.
