The Redmi Note 17 Pro Max stands out as Xiaomi’s endurance champion, packing a massive 10,000mAh silicon-carbon battery, a 6.83-inch 1.5K 120Hz display, a Snapdragon 6 Gen 5 chip, and 100W HyperCharge fast charging. It sets a strong benchmark for users who want multi-day battery life without carrying a rugged power-bank brick.
The five alternative devices featured in this lineup do not occupy the exact same price bracket as the Redmi Note 17 Pro Max, but they are selected specifically because they also pack enormous, high-capacity battery units designed for extreme longevity. If uninterrupted battery runtime is your top buying criterion, these five options deliver outstanding stamina.

The Realme P4 Power 5G is arguably the most direct alternative for buyers who want maximum battery capacity. Its 10,001mAh battery gives the phone exceptional endurance, while 80W wired charging helps reduce charging downtime. The device also features a 6.8-inch AMOLED display with a 144Hz refresh rate and is powered by the Dimensity 7400 Ultra.
The phone comes with LPDDR4X RAM and UFS 3.1 storage, providing a sensible combination for its price segment. Photography is handled by a 50-megapixel main camera and an 8-megapixel ultrawide camera. It also supports reverse wired charging, allowing the large battery to power accessories and other devices.
Realme promises three major Android OS upgrades and four years of security patches. That is not the longest support period in this group, but the P4 Power’s appeal lies primarily in its enormous battery and practical charging capabilities. For buyers who value endurance above almost everything else, it is difficult to overlook.
