iPhone 17 Pro Max's battery capacity rumored to be larger than its predecessor's

The iPhone 17 Pro Max will come with a larger battery than its predecessor's 4,685 mAh cell. According to a new rumor out of China today, the iPhone 17 Pro Max will finally be the first iPhone to reach 5,000 mAh.
As you may know, that's pretty much been the default capacity for flagship Android devices up until recently, when Chinese brands started using Si/C batteries thus taking them past that limit, while Samsung and Google have been content to stay around the 5,000 mAh mark, for now at least.

Throughout Apple's iPhone Pro Max line, every new generation brought with it a slight increase in battery size, aside from the iPhone 14 Pro Max which actually had an ever so slightly smaller cell than the iPhone 13 Pro Max.
