The iPhone 16 series features a big battery boost over final 12 months’s fashions. At the very least, that’s what Apple mentioned throughout the launch occasion final week.
Apple additionally informed us that it packed bigger batteries contained in the telephones, although it didn’t supply any specifics. Actual-life exams will inform us precisely how good the iPhone 16 batteries are. Till then, we’ve Apple’s official estimates for the iPhone 16 sequence, suggesting all 4 fashions supply battery life enhancements over their iPhone 15 predecessors.
However Apple’s estimates may also inform us that the iPhone 16 Professional and 16 Professional Max battery life could possibly be a lot better if you happen to flip off the At all times-On show function Apple launched two years in the past.
At all times-On show exams
The very first thing I did with the iPhone 14 Professional after I bought it again in September 2022 was flip off the At all times-On show. It was a signature function for the iPhone 14 Professionals, certain. I’m additionally satisfied that many individuals love seeing data at a look on the show. Nonetheless, I simply assume it’s overkill for my wants, the place I’m all the time one Face ID authentication away from notifications and fast app entry. Plus, who wants an At all times-On show on their iPhone when in addition they use an Apple Watch?
I loved nice battery life from day one, with the iPhone 14 Professional routinely lasting greater than a day. I used to be charging it each different day for the primary 12 months. The battery has aged since then, and battery life has degraded considerably, particularly after putting in the iOS 18 beta. However my iPhone 14 Professional nonetheless holds up properly, to the purpose the place I’m sure I might use it for one more 12 months. Of word, my At all times-On show continues to be disabled.
Just a few months after the iPhone 14 launched, some exams taught us precisely how a lot battery life the At all times-On show performance consumes. The iPhone 14 Pro used 16% of its battery to energy the At all times-On performance for twenty-four hours. That’s quite a lot of vitality. The iPhone 14 Professional with the show turned off misplaced virtually no battery life throughout the identical interval.
iPhone 16 battery life estimates
We already knew all that going into the iPhone 16 launch. At all times-On show will devour additional vitality on the iPhone 16 Professional and 16 Professional Max. How a lot vitality? Nicely, Apple’s own battery estimates for the four iPhone 16 models might assist with that.
Apple doesn’t checklist battery capacities on its web site for iPhones. As an alternative, it affords estimates for 3 eventualities: video playback, video playback (streamed), and audio playback.
Right here’s the battery life for every of the 4 iPhone 16 fashions for these eventualities:
Video playback
- iPhone 16 Professional Max – 33 hours
- iPhone 16 Professional – 27 hours
- iPhone 16 Plus – 27 hours
- iPhone 16 – 22 hours
Video playback (streamed)
- iPhone 16 Professional Max – 29 hours
- iPhone 16 Professional – 22 hours
- iPhone 16 Plus – 24 hours
- iPhone 16 – 18 hours
Audio playback
- iPhone 16 Professional Max – 105 hours
- iPhone 16 Professional – 85 hours
- iPhone 16 Plus – 100 hours
- iPhone 16 – 80 hours
What’s spectacular right here is that the 6.3-inch iPhone 16 Professional lasts so long as the 6.7-inch iPhone 16 Plus in video playback exams: 27 hours. The 16 Plus will get 2 additional hours of streamed video playback. You’d assume the iPhone 16 Professional would then virtually match the 16 Plus in audio playback exams when the show is turned off. That’s not the case.
There’s a 15-hour distinction between the 2. That is stunning, contemplating these two iPhones final simply as lengthy when streaming video. The display isn’t truly in use in audio playback exams, as within the video playback exams. The Plus has a much bigger battery than the Professional, certain. The Professional would have a extra environment friendly display, nevertheless it shouldn’t matter in audio playback exams.
How Apple examined battery life
The one factor left to query is the At all times-On show performance, which is unavailable on the Plus. Right here’s how Apple tested battery life for the audio playback situation.
Testing performed by Apple in July and August 2024 utilizing preproduction iPhone 16, iPhone 16 Plus, iPhone 16 Professional, and iPhone 16 Professional Max items and software program, subscribed to LTE and 5G provider networks. The playlist consisted of 358 distinctive audio tracks bought from the iTunes Retailer (256-Kbps AAC encoding), examined with stereo audio output. All settings had been default besides: Bluetooth was paired with headphones; Wi-Fi was related to a community; the Wi-Fi function Ask to Be part of Networks and Auto-Brightness had been turned off. iPhone 16 Professional and iPhone 16 Professional Max had been examined with At all times-On show enabled however with the show not seen; audio playback time will lower when At all times-On show is seen, in comparison with playback time when the show is face down on a floor or in a pocket or bag.
Apple says it examined audio playback with the show not seen. That suggests the display was positioned face-down on a floor. The At all times-On show function mustn’t work in that situation.
On the similar time, Apple does say that audio playback will lower when the At all times-On show is seen. Actual-life iPhone 16 battery exams would possibly assist clarify why the Professional can’t match the Plus in audio playback exams.
No matter Apple’s estimates, turning off At all times-On ought to enhance battery life. And if the display performance is responsible for the decrease audio playback estimate for the Professionals, then I’d think about the iPhone 16 Professional Max will final even longer than 105 hours with At all times-On turned off.
