Speed and camera performance are the most eye-catching features of the new smartphones, but stamina should not be overlooked. And it appears that the upcoming iPhone 16 Pro family will be enhanced in this department as well.

According to Weibo leaker Instant Digital, the 16 Pro will feature a 3,577mAh battery, up 9.25% from the iPhone 15 Pro's 3,274mAh. iPhone 16 Pro Max's battery capacity will also increase by 5.74%, from 4, 4,676mAh from 422mAh.

This improvement could possibly be related to Stacked Battery Technology.

If this is the case, it would also narrow the gap between the two models' batteries: the 1,148 mAh difference between the iPhone 15 Pro and Pro Max would be reduced to 1,099 mAh in the new figures. While this is still an important number for users who value stamina above all else, it is an equally welcome increase for Pro users.

The improved battery capacity is something Apple has generally offered every year. If you've been using an older model and are considering an upgrade, you may be in for a pleasant surprise (especially since capacity is likely to have declined over time).

Interestingly, we have heard both Instant Digital numbers before, but from different leakers.

@lipilpsi had previously stated 3,577mAh for the smaller Pro model, while we thought the Pro Max would reach 4,747mAh. Meanwhile, in April, another Weibo tipster (Baby Baby Sauce) put the Pro Max at the same 5,676mAh figure we are hearing today, while the Pro was little changed from the previous model at 3,355mAh.

Whichever figure you think is most likely, what all three leakers seem to agree on is that the battery capacity has gone up, and that when combined with the increased efficiency of the new A18 Pro chipset, you'll be spending more time away from your charger That is. In fact, it is rumored that Apple may claim that the iPhone 16 Pro Max will allow for 30 hours of use.

Not only will the charging interval be longer, but the time spent charging may also be reduced. According to recent rumors, the iPhone 16 Pro series will benefit from 40W wired charging and 20W wireless MagSafe charging. While this is far from the 80W/50W offered by the OnePlus 12, it is considerably more than the 27W and 15W currently offered.

One need not wait long to find out which numbers are correct. Virtually every numbered iPhone for the past decade has been released in September, and the iPhone 16 family will almost certainly be announced next month; along with the four new iPhones, we expect the Apple Watch X to be unveiled as well,
