With the upcoming release of the iPhone 17, many are contemplating whether to upgrade now or wait for the iPhone 18. One key factor to consider is the battery life of the devices. Apple has introduced its in-house cellular modem, the C1, in the iPhone 16e and is expected to continue using it in the iPhone 17 lineup. However, the iPhone 18 Pro is rumored to feature an upgrade that may improve battery performance. Additionally, Apple is rumored to be increasing the battery capacity in its upcoming models, including the iPhone 17 Air. If battery life is a priority for you, waiting for the iPhone 18 Pro may be the better choice.
