CPUTool lets iOS jailbreakers underclock their CPU and GPU

Apple doesn’t provide much by way of power savings on the iOS platform apart from the Low Power Mode feature and the use of general common sense with regard to reducing battery drain. Fortunately, those looking for more than what Apple seems willing to provide out of the box might be in luck as of this week.

Say hello to CPUTool, a newly released jailbreak tweak created by iOS developer Soh Satoh that lets the user underclock their handset’s CPU and/or GPU performance in an effort to optimize power consumption.

What is the Mac Activity Monitor and how do you use it?

Energy Tab Activity Monitor

The Activity Monitor on your Mac is one of those tools that you should become familiar with. You by no means need be an expert on it, but you should know the basics. Why, you ask? Because the Activity Monitors shows all the processes running on your Mac. It’s like a task manager, so you can see how those processes affect your Mac and close any if needed.

Whether you’re new to Mac or simply new to the Activity Monitor, we’ll walk you through the basics you need to know.

10 ways Apple could improve the MacBook Pro

Apple’s MacBook Pro has been my personal computer of choice for almost a decade now, and while I’ve loved every upgrade along the way, I can’t help but feel like Apple could do better.

Given just how expensive a MacBook Pro becomes as you start pegging out the specs on Apple’s website, it seems like Apple could do more to help me justify the price point. With that in mind, I’ll discuss at least ten ways Apple could improve their flagship notebook in this piece.

Benchmarks confirm iPhone XR brings iPhone XS-like speed but with a longer battery life

All new iPhones run Apple's latest A12 Bionic system-on-a-chip and synthetic benchmarks like Geekbench 4 confirm this. According to the CPU, GPU and GPU compute scores for iPhone XR, Apple's colorful phone basically offers identical performance to the premium iPhone XS and iPhone XS Max smartphones, but in a package with a longer battery life that costs $250 less.

Your iPhone X or iPhone 8/8 Plus might one day get throttled by Apple

Late last year, Apple was caught throttling iPhones that had degrading batteries. This lead to class action lawsuits, a discounted battery replacement program, and various meetings with regulators around the world. It also forced Apple to add a battery monitoring tool in iOS 11.3. With the 2018 iPhones now in stores comes word that last year's handsets might eventually be throttled too.

As first discovered by The Verge, the recently released iOS 12.1 update brings Apple’s controversial “performance management feature” to the iPhone X, iPhone 8, and iPhone 8 Plus for the first time. With this tool, Apple can dynamically throttle the devices (i.e. slow them down) as the battery degrades in order to stop random shutdowns.

An Apple support page explains:

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. For iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, and iPhone 7 Plus, iOS dynamically manages performance peaks to prevent the device from unexpectedly shutting down so that the iPhone can still be used. This performance management feature is specific to iPhone and does not apply to any other Apple products. Starting with iOS 12.1, iPhone 8, iPhone 8 Plus, and iPhone X include this feature, but performance management may be less noticeable due to their more advanced hardware and software design.

No doubt this news will lead to some more criticism against Apple. However, it's probably no longer justified. If you own one of last year's phones, you can turn off the performance management feature.
