iPhone 17 Pro Max to Feature Biggest Battery Boost Yet, Leak Suggests

Apple’s next flagship, the iPhone 17 Pro Max, may deliver a major upgrade in battery capacity, potentially crossing the 5,000mAh mark for the first time. According to a recent leak by tipster Instant Digital on Weibo, this would be a significant jump from the iPhone 16 Pro Max’s 4,676mAh battery and the iPhone 15 Pro Max’s 4,422mAh cell, making it the largest battery ever in an iPhone.

This increase isn’t just about numbers; it promises longer screen time for photos, social media, streaming, and gaming—reducing the constant need to recharge. Coupled with Apple’s next-gen A19 Bionic chip and iOS optimizations, the iPhone 17 Pro Max could offer improved power efficiency alongside its beefier battery.

The Pro Max model’s larger size provides extra space for a bigger battery, something standard and Pro models lack. Apple has traditionally prioritized balanced hardware and software over just battery size, but with rising user demands and competitive pressure from Android phones that crossed 5,000mAh years ago, this could be a turning point.

Expected to launch in September 2025, the iPhone 17 Pro Max’s rumored battery boost is generating excitement among users eager for longer-lasting iPhones. Until Apple confirms, this remains a rumor—but one that’s gaining momentum. For power users and everyday users alike, 2026 might finally be the year for a truly battery-hardy iPhone.
