Apple's iPhone 17 Pro Max is rumored to feature a significantly larger 5000mAh battery, a nearly 10% increase compared to its predecessor. This substantial upgrade, revealed by leaker Instant Digital, will likely result in improved battery life, although the exact increase depends on various factors including software optimization. The larger battery necessitates a thicker and heavier phone design. While a larger battery doesn't guarantee proportionally longer usage, it's expected to be the longest-lasting iPhone yet.
