iPhone 18 Pro Adaptive Power does nothing for the first 7 days
Adaptive Power is the iPhone battery setting people go looking for first, and on a phone you have just taken out of the box it will not do anything at all. Apple’s wording is flat: “Adaptive Power needs at least 7 days to learn your charging habits, so it won’t engage before then.” The A20…

Owning an Older iPhone: What Apple Still Charges for Battery Service
Vintage status does not carry its own price list. What Apple does publish, on a separate battery-replacement page, is an out-of-warranty fee that would apply to an eligible older iPhone the same way it applies to a current one: $99, or $0 under AppleCare+. Apple's battery-replacement page does not reference vintage or obsolete status by…

Apple states that AirPods 5 run up to 4 hours with Active Noise Cancellation on, or up to 5 hours on the model with the Wireless Charging Case, and up to 20 or 22 hours total with the case topping them up. It has never published a milliamp-hour figure for either battery, in the earbuds…
iPhone Duo's 44-Hour Battery Claim Is Real, but It Is Not the Whole Number
Apple does publish a 44-hour battery figure for iPhone Duo, so the number itself is not invented. What is getting flattened into a single headline is that 44 hours applies only to video playback on the phone’s outer display. Apple’s own tech specs list two lower figures alongside it, for the inner display and for…
Do AirPods 5 and the Wireless Charging Case Model Have Different Earbuds?
Apple’s own pages rate the standard AirPods 5 at up to 4 hours of listening with Active Noise Cancellation on, and the AirPods 5 with Wireless Charging Case at up to 5 hours, even though the tech specs for both list the same earbud weight, the same dimensions, and the same H2 chip. Apple has…
AirPods 5 at $129: What You Actually Get, and What Only the $149 Model Adds

iPhone Duo Battery Capacity: Apple Publishes Hour Ratings and Nothing About Its Two Cells
Apple publishes five battery hour ratings for the iPhone Duo and not one number about the cells that produce them.

Screen Dim and Charging Stalled After the iOS 27 Update? Apple Documents It as Heat Protection
