iPhone 17 Pro Max Battery Capacity Reportedly Leaked

Apple is expected to announce the iPhone 17 lineup in September. Reports indicate that the iPhone 17 Pro Max may be thicker and heavier to accommodate a larger battery.

Battery for iPhone 17 Pro Max

A recent post on Weibo by leaker Instant Digital suggests the iPhone 17 Pro Max may have a battery capacity of approximately 5,000mAh. This would represent the largest battery capacity in an iPhone to date.

The 5,000mAh figure is considered an estimate rather than a confirmed specification. However, it provides an indication of the potential increase in battery size for the new Pro Max model.

For reference, previous models had the following battery capacities:

• iPhone 16 Pro Max: 4,676mAh
• iPhone 15 Pro Max: 4,422mAh
• iPhone 14 Pro Max: 4,323mAh

Depending on the final capacity, the increase could be close to 10% compared to the previous model.

Battery Life Considerations

It is important to note that battery capacity does not directly translate to proportional improvements in battery life. The actual usage time will depend on several factors, including software optimizations in iOS 26.

The larger battery is expected to improve battery life for the iPhone 17 Pro Max. However, the extent of this improvement will be determined by additional variables.
