iOS 13.1 will bring processor throttling to the iPhone XS and iPhone XR

Apple’s iOS 13.1 is set to launch on September 24, just four short days after the launch of iOS 13 on September 19, and according to an Apple support page, Apple will add a processor throttling feature to the iPhone XS and XR with the update.

The feature itself was first discovered in iPhones in 2017 and proved to be controversial. It’s aimed at limiting the performance of iPhone models to prevent them from shutting down due to aging batteries — but the result, as you might expect, is an iPhone that runs slower than it otherwise would. Throttling gets heavier as the battery continues to age, your phone will perform much faster if the battery is replaced.

When the feature was discovered, Apple ended up detailing exactly how it works in an effort to calm backlash. The company also offered discounted battery replacements to users with some iPhone models, ensuring that devices that might otherwise be throttled could return to their full performance. Not only that, but it even added a switch in the Settings app that allowed users to turn off the processor throttling, though of course, users found that their phone might shut down, especially in processor-heavy situations.

That said, Apple seems to have been working on the feature to refine it a little, and it says that newer iPhone models are better at power monitoring and the impact of the processor throttling shouldn’t be quite as obvious. That more advanced hardware was first introduced on the iPhone 8 and iPhone X, but was also present on the iPhone XR and iPhone XS.

Apple has yet to disclose whether or not the iPhone 11 range will eventually get processor throttling. However, a report from 9to5Mac notes that an Apple Support page mentions that the new phones offer an even more advanced power monitoring system. That system can manage performance, so it’s possible there’s some kind of processor management in place from the start. Presumably, that system will work more as the battery ages, though hopefully the effects of that won’t be felt quite as hard as on older phones.

While Apple did face backlash, the simple fact is that as batteries degrade over time, they’re unable to provide as much power over time as they once could. As a result, performance needs to take a hit to ensure that the device stays powered on.

The iPhone 17 Air might not stack up in terms of battery life
Alleged concept render of the iPhone 17 Air in black.

Concerns over iPhone 17 Air battery life might have been spot-on, according to a new report from The Information. Apple allegedly conducted internal tests that showed only 60 to 70 percent of iPhone 17 Air devices would make it through the day without needing a recharge, versus between 80 to 90 percent for other iPhone models.

Of course, part of that is due to the design of the handset. At just 5.5mm, the iPhone 17 Air is set to be the thinnest iPhone ever (and one of the thinnest phones on the market overall), but it might come at the cost of battery capacity. To help offset this problem, Apple is supposedly planning to launch an optional battery case accessory to give users a little bit more juice to get them through the day.

Galaxy S25 Edge leak reveals a look that’s almost iPhone Air like
Galaxy S25 Edge

Two highly anticipated smartphone models are set to launch before the end of the year: Samsung’s Galaxy S25 Edge and Apple’s iPhone 17 Air. Newly released images of the Galaxy S25 Edge, scheduled to arrive this month, reveal a striking resemblance to rumored images of the iPhone 17 Air, which is expected to hit the market in September.

The Galaxy S25 Edge, which Samsung teased earlier this year, will arrive on May 13. When the phone launches, it’s expected to be one of the thinnest smartphones in the world.

iPhone prices are increasing, but not for the reason you think
Apple Invites on iPhone.

The average sales price of iPhones is increasing, but it isn't for the reason you think — or at least not entirely for that reason. According to new data from Consumer Intelligence Research Partners (CIRP), the average price of an iPhone has increased by $18 to $971. That's up from $953 in the fourth quarter of 2024.

While many are quick to point to tariffs as the cause, the impact of economic factors isn't clear yet. The current trend towards higher-priced iPhones lies entirely in Apple's recent decision to end the iPhone SE and iPhone 14 lines. Analysts use metrics like the U.S. Weighted Average Retail Price (US-WARP) to determine the average sale price, since Apple stopped publicly reporting those numbers at the end of 2018.
