Report says iOS 27 will improve the battery life on iPhone handsets
This year, iOS 27 is expected to improve the battery life on compatible iPhone models once the update is installed. The latest report about iOS 27 has Apple focusing on performance by reworking some of the operating system’s code. Previously, the internal codenames for iOS 27 and macOS 27 were said to be Buttercup and Honeycrisp respectively. Now, the codenames are said to be Rave and Fizz. The new codenames are more aggressive sounding which indicates Apple’s desire to focus on performance.
The iPhone’s Neural Engine will run more effectively saving battery life
This allows the calculator and compass apps, older built-in apps, to run more efficiently leaving more battery life for users. Engineers are said to be working on ways for the Neural Engine to also run more efficiently, perhaps by throttling the AI processor to prevent AI tasks from draining the battery so quickly. One way to do this would be to look at the temperature and current health of the battery and instead of running AI processes at full speed right away, “drip-feed” the AI tasks to the Neural Engine.
The iPhone battery will hit a milestone in 2026 and one model will sport the largest iPhone battery ever used
Apple also plans to make a change to iOS 27 when it comes to the re-indexing that is led by the Neural Engine during the first 48 hours after you update your iPhone. Re-indexing your complete photo and file library is the cause of the first 48-hour battery drain on your iPhone. Gurman says that Apple will introduce a new background management system that extends this re-indexing over a longer period of time. This will help the battery stay cool and keep the battery from draining too fast immediately following the update.
It seems that for those iPhone users who care about battery life, and we know who you are, 2026 will be a bumper year for you.
