I was just thinking about something related to battery life on the iphone 6/7/8 form-factor. I just looked up the teardown on ifixit and wondered why apple didn't consider other tradeoffs in the device to improve battery life. Since this is supposedly now a budget phone and not just a small phone, does it really need a taptic engine or the wireless charging? Would that even be enough to make a difference in size for the battery? If so I would trade those two things in a heartbeat for a decent increase in the battery size.
I think the whole point behind the SE’s lower pricing is that Apple doesn’t have to spend any money redesigning the innards. They use an existing production process which already works and which has had 4 years to write off the initial investment. Just slap on a new processor and call it a day.
