Apple says slower performance of older iPhones is intentional

-text c-gray-1" >You're not alone if you've noticed a slowdown in the performance of your older iPhone. The thing is, it may be more related to your battery than the phone itself. After a post on Reddit and a followup by benchmarking software Geekbench's founder, Apple told TechCrunch that it released a fix for premature shutdowns last year for iPhone 6, 6s and SE by smoothing out CPU demand when a battery is older, cold, or just low on juice. Apple also said that it recently extended this slowdown feature to iPhone 7 devices running iOS 11.2, and plans to «add support for Geekbench Geekbench Score Geek bench antutu Score other products in the future.»

A couple of weeks ago, Reddit user TeckFire ran some CPU benchmarks (via Geekbench) on his iPhone 6 Plus before and after he replaced its battery. He found that CPU performance was significantly better after a battery replacement, which he attributed to Apple slowing down phones with low capacity batteries. A week later, Samsung Geekbench's own John Poole wrote a post that pointed to Apple's involvement. In essence, Poole says that Apple introduced code to iOS that limits iPhone performance when battery charge is low, which could be interpreted as a CPU issue leading to users replacing their iPhone instead of their battery. While this may not be Apple's intent in this case, it's not hard to see users being confused and blaming the company for planned obsolescence practices, especially as Apple benefits from user confusion and iPhone upgrades.

Primate Labs posts new iMac benchmarks

-text c-gray-1" >

The company that provides the amazing Geekbench benchmarking software, Primate Labs, has run its tests on the new 21.5-inch iMac and found that it's a pretty impressive piece of hardware.

Primate Labs tested all of the configurations of the new iMac, but it's the top-of-the-line unit sporting an Intel Core i7-3770S clocked at 3.1 GHz that tops the speed test for all iMacs. To quote the benchmark post, «The benefits Geekbench Score Geekbench Score of the new Ivy Bridge processors are Samsung Geekbench Scores clear; the new high-end 21.5-inch iMac is almost 10 percent Geek bench antutu faster Geek bench antutu than the old high-end Geekbench Score 27-inch iMac.»

The benchmark score for the high-end 21.5-inch iMac was 12,447, while that of the old (mid-2011) high-end 27-inch iMac was 11,410. A comparison to the high-end 2012 Mac mini shows that it's no slouch, either — it came in at 11,595. Of course, if you want to kick some serious computing butt, you'll still need to get a Mac Pro — the fastest 12-core unit weighs in at a Geekbench score of 22,271.

It should be interesting to see the results for the 27-inch iMac that will be shipping in about two weeks. The top-end unit features a 3.4 GHz Intel Core i7 that will likely leave the 21.5-inch model in the dust.

iPad Air: Unboxing, first impressions and benchmarks

-text c-gray-1" >
Today's the first day of availability for the new iPad Air, and after totally forgetting to order it online at 1 AM MT, I got onto the online Apple Store at around 7:30 AM to order one. After confirming that the model I wanted — 32 GB, silver, AT&T — was in stock at the Aspen Grove Apple Store in Littleton, CO, I pushed the button. I picked it up at around 11:30 AM, and was in and out of the store in about five minutes.

I'm one of those sick individuals who tends to hold onto the old boxes for my Apple products, so I was able to do a quick size comparison with the 3rd-generation iPad and iPad mini. The box was the same height and thickness as that of the iPad, but not as wide. With that silliness out of the way, it was time to grab the scissors and actually open the box:

I apologize for the video quality, but I get sooo excited with a new iPad. Some people like new cars, some people get excited about new clothes, I love new tech.

It's when you first get your hands on the iPad Air that you realize just how good a job Apple did at trimming the weight. It weighs only about 6 ounces more than an iPad mini, as you'll see in the weigh-in pictures in the slideshow below.

I found the display on the iPad Air to be slightly brighter than that of the 17-month-old 3rd-generation iPad at the same brightness setting, and it had a slightly warmer tint to it. There's a side-by-side image in the slideshow that demonstrates this.

In terms of speed, the Air seems to be quite snappy. «Snappy» isn't a good quantitative unit of measure, so I installed Geekbench Scores 3 on all three iPads to get a much better picture of exactly how fast they all are:

SIngle-Core Score Multi-Core Score

iPad Air 1469 2675

iPad (3rd-Gen.) 262 494

iPad mini (1st-Gen.) 259 468
Yes, the iPad Air is FAST. All apps except Geekbench were shut down and the devices were restarted before running the benchmark. The device specs are as follows:

OS Version 7.0.3 7.0.3 7.0.3

All in all, my initial impressions of the iPad Air are very favorable. I hope to do some additional tests in the near future for publication here on TUAW.
