Earlier, the battery capacities of the latest iPhone models were revealed, thanks to TENAA, and confirms that the newest devices have bigger batteries than their last year’s counterparts. Now, a Vietnamese YouTube channel has done a whole iPhone 11 Pro Max teardown, not only confirming the battery size but also revealing other details that Apple didn’t reveal in its September 10 keynote. We believe this teardown carries significant importance because the innards are vastly different than the components used in the iPhone XS Max, showing that not all changes need to represented from the outside.

Since the video is in Vietnamese, it’s hard to make out what’s being said but a couple of things are crystal clear. First off, the first non-iFixit iPhone 11 Pro Max teardown has revealed that the phone has a rectangular logic board and not an L-shaped one like present in the iPhone XS Max. This compact, stacked design supposedly freed up space to fit in larger batteries and additional camera sensors inside the iPhone 11 series.
