Better Battery Life
Apple tends to work on making at least some improvements to the battery life of its iPhones each year, but despite reports of lower-power LTPO displays, we wouldn’t expect battery performance to take a huge jump.
Instead, the LTPO technology will almost certainly be used to allow the display to remain on in certain modes without sacrificing battery life, in the same way Apple did with the Apple Watch Series 5, which introduced the first Always On Display in an Apple product while still maintaining the same 18-hour battery life of its predecessor.
That said, Apple seems to be less obsessively focused on ultra-slim iPhones these days, and it’s shown a willingness to pack in bigger batteries even if that comes at the expense of thickness, so there’s little doubt that Apple will have some impressive battery numbers to share when it takes the stage to debut the new iPhones later this year.
