iOS 10.2.1 added battery health to the list of things included in the advanced power management system on iPhone. Flash forward and, after customers complained about excessive performance issues, Apple is now offering battery replacements at a reduced price and will update iOS to provide better insight into battery health. But what about iPad? Should iPad customers also be worried about performance throttling or battery health?
No, at least not as far as Apple has indicated to date.
Why aren't iPads affected by Apple's power management throttling?
Because Apple hasn't added them to the same battery health-based power management system.
From Apple Support, emphasis mine:
With a low battery state of charge, a higher chemical age, or colder temperatures, users are more likely to experience unexpected shutdowns. In extreme cases, shutdowns can occur more frequently, thereby rendering the device unreliable or unusable. iOS 10.2.1 (Released January 2017) includes updates for previous models of iPhone to prevent them from unexpectedly shutting down. This includes a feature for iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE to dynamically manage the instantaneous performance peaks, only when needed, to prevent the device from unexpectedly shutting down. This capability was also extended to iPhone 7 and iPhone 7 Plus with iOS 11.2, and we will continue improving our power management feature in the future. This feature's only intent is to prevent unexpected shutdowns so that the iPhone can still be used.
Apple specifically calls out iPhone — and more specifically, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE.
It's possible that a very old iPad with very poor battery health could have trouble dealing with spikes but, since Apple hasn't added them to the power management system, they'd shut down the same way iPhone 5s and previous iPhones would.
Could Apple add iPads to the same power management system?
Theoretically, but iPads have significantly bigger batteries than iPhones. That means they can better handle instantaneous performance peaks over a much, much longer portion of their battery life.
Never say never, but it's not something that's happening now.
But what if your iPad is slow?
There are several things that can affect iPad performance. Excessive heat, for example, has always and will still cause processors to ramp down on any device, including iPads. So can the cruft and bit rot that builds up over months and years of use.
You can try rebooting or even backing up and restoring to improve performance.
If Apple does start throttling iPads to preserve battery health, will you update?
Absolutely. For now, though, cancel the red alert.
