These are the variants of the iPhone 16 that are anticipated to have notable battery upgrades this year. The iPhone 16 Pro Max is expected to have the longest battery life of any iPhone to date, while Apple indicates that the iPhone 16 and 16 Plus will see a significant bump. We'll evaluate these claims for veracity and figure out how long the battery will run for. iPhone 16 Pro Max ($1,199), iPhone 16 Pro ($999), iPhone 16 Plus ($899), and iPhone 16 ($799) are in the list. We'll assess these new phones in contrast to the flagship Samsung Galaxy S24 Ultra and the base and top-tier iPhone 15 Pro Max from last year. Based on regular everyday activities, the testing has commenced.
