UI Performance concerns on OS X El Capitan and Yosemite

A few weeks ago, OS X El Capitan (10.11) was released. I took the chance to test it for a few days – just to replace it again with Mavericks (10.9). Let me explain why.

When Apple released Yosemite in 2014, they did a major update to it’s design. Not only the system font has changed from Lucida Grande to Helvetica Neue (and to San Francisco in El Capitan to address some readability issues on non-retina displays), but also many things under the hood have been changed. These changes to the UI system made Yosemite and El Capitan responding slower than Mavericks. But that’s something that you’ll eventually only notice if you’re having a dual-boot system with both versions running on the same device. I can definately work faster with 10.9 as with any newer OS X versions, because everything responds faster.

With El Capitan, Apple simply continued where they left off with Yosemite. Especially in bringing their Apps up-to-date with the new UI design introduced with Mavericks and improvements regarding security mechanisms with the system itself. They also have improved the performance. Unfortunately, the performance is still not the same as with Mavericks.

Some further issues discovered with El Capitan were:

  • Finder canceled renaming files when the list of file reached the bottom. This was freaking me out when renaming files in directories with hundrets of items.
  • PDF documents look somehow blurry. This wasn’t the case with Yosemite and Mavericks.
  • They have a new beach ball. But I see it even more often than in previous OS X versions. Not good.
  • Disk Utility was redesigned. While it perfectly fits into the rest of the system design, some things have been changed (especially the partition stuff works a bit different). Humans don’t like changes, you know… 🙂
So at the end of the day I ended up restoring my Time Machine backup to have Mavericks back on my device. For users of retina-based devices, Yosemite or newer is a must, as only those versions have full retina support.

Apple iPhone 6S Battery Issues

When I bought my first Apple product back in 2001, I was thrilled to have something that looks great, has great capabilities and yet does a good job. It was an iPhone 4S, for which I paid around 630 € back then. However, that phone was not working well with recent iOS versions, since it’s hardware specs are somehow outdated (well, everything older than two weeks is out-dated nowadays).

So I decided to get an iPhone 6S. The presentation of the latest iPhone in Apple’s September Event looked promising. More processor power, more GPU power, 3D Touch and so on. A well designed device with current technology. Three days ago my phone was delivered. After unboxing, I charged it until the Battery was full and then started setting it up. I did not recover any existing backup.

The next day I encountered an issue with the device. While not fully set up (a lot of Apps I use were not even installed), the battery drained pretty quickly, while the phone was on Standby for 95% of the time. A full battery lasted for about 12 hours. Later that day I contacted Apple Support and told them that the battery was draining for no reason. They remotely tested the device via their diagnosis tools and told me that everything is fine. They recommended me to reset the settings. I did that. I even did a factory reset – without success. Again I contacted Apple’s support and the result was the same: The device is fine, all I can do is bring it in for service. Unfortunately the next free time slot in my local Apple Retail Store is in more than a week. So I might go and get it checked there to find out what’s wrong with it.

For me, it’s an hardware issue. With no apps installed, Bluetooth, location services and many background services turned off, the phone is not meant to consume a lot of energy at all. My OnePlus One lasts at least one and a half day with average use and a fully charged Battery. That’s what I expect. I know that Apple reduced the battery capacity for the 6S compared to it’s predecessor, but it shouldn’t be that dramatic.
