iOS 9.0.1 on iPhone 6: First Impressions and Performance

This has only been one way since iOS 9 release, and Apple has already moved on. Today, the company has released a new iOS 9.0.1 update that aims to fix some of the most glaring iOS 9 issues. We spent a few hours with the iPhone 6 iOS 9.0.1 update, and here’s what we found.

Last week, Apple released an all-new iOS 9 upgrade for the iPhone 6 and other iPhones and iPads. First announced at WWDC 2015 in June, the update brings a host of big time features to the iPhone, including improved battery life. This is a big reason why over 50% of iOS users upgrade.

The company also confirmed that an iOS 9.1 update is coming for the iPhone, iPad and iPod touch, but we now know that it will not be a successor to iOS 9.0. That honor belongs to the company’s brand new iOS 9.0.1 update.

iPhone 6 iOS 9.0.1 release date is here and here with no warning from Apple. Like iOS 9, the iOS 9.0.1 update was also revealed around 10:00 PT. Unlike its predecessor, this new iOS 9 update is nothing more than a bug fixer aimed at fixing issues.

However, that doesn’t mean you have to let your guard down. As I’ve mentioned hundreds of times, even the smallest iOS updates can cause problems for the iPhone, and that’s exactly why I want to take a closer look at its performance today.

My initial iPhone 6 iOS 9.0.1 update impressions don’t serve as my final review of the software, but it should help those who are feeling a bit indecisive. Note that you don’t need to install iOS 9.0.

iOS 9.0.1 Installation

Apple’s new update arrived today without warning, exactly one week after the release of iOS 9. And while iOS 9.0 was plagued with release date installation issues, iOS 9.0.1 didn’t produce the same kind of issues.

I downloaded the update shortly after it arrived and was able to download and install the 20MB update in about 10 minutes over a fast connection. The download didn’t take long but the installation on the phone took about seven minutes to complete. Unusually long for an update of this size (at least for my device).

Importantly, I did not encounter any problems during the download process or during the installation process. I haven’t heard or seen any major issues so if you decide to download it later today you should be fine.

If you run into installation problems, be sure to consult our list of fixes. It has several solutions for iOS 9 update issues.

iOS 9.0.1 on iPhone 6 Performance

These impressions won’t go into iOS 9 features. If you haven’t installed the iOS 9 update yet, you’ll want to check out our iOS 9 review or our ongoing iOS 9 coverage for more on the improvements that come with Apple’s new update.

These impressions are performance-oriented, as they should be. iOS 9.0.1 is all about fixing some issues that were overlooked with the original iOS 9 release last week.

Before I get down to business, I want to remind you that I am only one person with a version of the AT&T iPhone 6.

I probably don’t use the apps you use, and I probably don’t use my iPhone 6 the way you do. It’s important to pay attention to this as the distance is always changing when it comes to iOS updates. Use my thoughts and ideas as a general guide.


For the most part, app performance was solid on my iPhone 6 with iOS 9. Most of my core apps (Asana, Slack, YouTube, Twitter, Instagram, Gmail, Hangouts, Chrome, Dark Sky, Amazon, SoundCloud, Spotify, and Xbox One Smartglass) all work fine. The key word here is to be the most.

Google Chrome is bothering me. In the last week it crashed more than 50 times, sometimes when I only had one tab with CNN open. It was extremely frustrating, especially since the last Chrome update came with iOS 9 support.


In my limited time with iOS 9.0.1, I did not notice any problems with my core apps or secondary apps. I have about 100 apps on my device. Chrome is behaving right now, but the real test will be tomorrow, Friday, and over the weekend.

became see and hear complaints about broken apps, even in the hours after the iOS 9.0. If downloading the latest bug fix update doesn’t help, try reinstalling the app. This has worked for me in the past. If that doesn’t work, contact the developer.

iOS 9.0.1 Battery Life

iOS 9 battery life was solid during my week with iOS 9.0 and now that I have iOS 9.0.

I’ve been using the device for several hours, I can add extensively, and I haven’t discovered anything out of the ordinary. It holds a solid charge when in use and in standby mode.

In the few hours since the update was released, I haven’t heard of any major battery life issues with iOS 9.0.1, but that doesn’t mean they don’t exist. Battery drain issues almost always occur after an update is released.

If you see something strange, wait a day or two before making drastic changes to your habits or iPhone 6. Battery life sometimes falls into place after two days.

If nothing changes, check our list of fixes and tips.

Wi-Fi, Cellular Data and Bluetooth

I’ve tested the iPhone 6 and iOS 9.0.1 update with several different routers and haven’t had any issues. Yet.

I’ve also successfully paired it with a few different Bluetooth devices, including speakers and a few pairs of headphones. No problem there either.


AT&T’s LTE network still works fine for me (I live in Los Angeles) and I don’t expect any problems with it in the future.

iOS 9.0.1 Issues on iPhone 6

Not yet. Massive hero level issues often jump off the page after an update. Touch ID and cellular data issues affecting iPhone 6 and iPhone 6 Plus owners right after the iOS 8.0.1 update are just one example.

I haven’t noticed any game-changing bugs but I’ve only been using the update for a few hours. Smaller issues are much more difficult to detect and can take days or even weeks (never) before I notice anything out of the ordinary.

I’ll keep my eyes peeled but so far the iOS 9.0.1 update seems stable on the iPhone 6. If you’re seeing issues, check our list of fixes.

iOS 9.0.1 is a minor bug fix update and specifically targets three bugs. If you need a reminder, here they are:
