Nexus 5 Android 4.4.4 KitKat Update Review: Two Weeks Later

Last month, Google rolled out two Android 4.4 KitKat updates to the Nexus 5 including a Nexus 5 Android 4.4.3 KitKat update and an Android 4.4.4 KitKat update. We’ve been using the latter on the Nexus 5 for two weeks and with Android 4.4.4 KitKat problems swirling, we want to take another look at how the update is performing on Google’s current Nexus.

June was a hectic month for Google. Early in the month, the company rolled out a brand new Android 4.4.3 KitKat update that replaced Android 4.4.2 KitKat was aimed, primarily, at Android 4.4.2 KitKat problems. The update also brought cosmetic changes to the dialer and the People application but the update is essentially a massive bug fixer.

Android 4.4.3 KitKat rolled out for several days and up until the middle of the month when Google surprisingly rolled out an Android 4.4.4 KitKat update. Android 4.4.4 KitKat is a small security update for Nexus users that updated to Android 4.4.3 KitKat. It patches up an OpenSSL vulnerability. Like Android 4.4.3 KitKat, Android 4.4.4 KitKat is a small, bug fixer.

In the days since these two Android 4.4 KitKat roll outs, we’ve also seen Nexus users complain about a host of Android 4.4.3 KitKat problems and Android 4.4.4 KitKat problems. These problems range from battery life issues to GPS problems to issues with Exchange. Many of them are lingering Android 4.4.2 KitKat problems that Nexus users say were not fixed inside Android 4.4.4 and Android 4.4.3.

Nexus 5-Best-Cheap-Phone-June 2014

Two weeks ago, we issued our initial review of Android 4.4.4 KitKat on the Nexus 5 in an effort to generate discussion and offer some feedback to Nexus 5 owners on the fence about the upgrade. Today, with Android 4.4.4 KitKat complaints emerging by the minute, we want to take another look at how the Android 4.4.4 KitKat update is performing two weeks after we installed it on the Nexus 5.

Keep in mind, this Nexus 5 is stock and has always run stock software. We have made no modifications to the software since it was picked up back in November at launch.

Nexus 5 Android 4.4.4 KitKat Update Performance

Over the past two weeks, I’ve heard and read numerous complaints about the Android 4.4.4 KitKat update. Several Nexus 5 owners chimed in with their problems and Google’s Nexus product forums are rife with Android 4.4.4 KitKat problems. So, I felt it appropriate to revisit the Nexus 5 Android 4.4.4 KitKat update in an effort to provide some feedback to those that are wavering and hopefully generate some discussion amongst Nexus 5 owners along the way.

As I’ve noted many times, when it comes to the performance of incremental updates like Android 4.4.4 KitKat, I like to look at five different areas in particular. Those areas include applications and how they’re performing post update, battery life and whether there is abnormal drain, bugs or hiccups, Wi-Fi, Bluetooth and cellular performance, and overall speed. After spending two weeks with the Android 4.4.4 KitKat for Nexus 5, here is what I’ve found.


Applications will often start behave badly after a small update like Android 4.4.4 KitKat so that’s why it’s important that I note that I haven’t run into any serious problems with my applications, stock or otherwise.

Google Maps, Hangouts, Mail, Calendar, and Drive are all performing admirably and I haven’t run into any issues with any of them since I installed the update two weeks ago. Same goes for apps like Instagram, Amazon, Yelp, Facebook, Twitter, YouTube, and Spotify. All of them are performing as they should after Android 4.4.4.


If you are dealing with issues with apps inside of Android 4.4.4 KitKat, and I’ve heard various complaints about various apps, you’ll want to ensure that you’re up to date. If the app is running the latest version, it’s then worth reaching out to the developer to report the issue.

Some other fixes include force stopping the app and restarting it, clearing your cache and your data, or simply installing and reinstalling the app. These are known fixes but they aren’t guaranteed to work.

To force stop an application:

  1. Hit your device’s Home button.
  2. Head into Settings.
  3. Tap Apps.
  4. Find and tap the app that’s not working.
  5. Tap Force Stop.
  6. Re-launch the app.

To clear your cache and data:

  1. Hit your device’s Home button.
  2. Head into Settings.
  3. Tap Apps.
  4. Find and tap the application that’s not working.
  5. Tap Force Stop.
  6. Hit Clear Data.
  7. Tap Clear Cache.

Android 4.4.4 KitKat Battery Life

Battery life complaints emerge after every Android update, after every iOS update from Apple, after every Windows Phone update from Microsoft. It’s just how it goes. Once in awhile, there is actually a serious battery drain bug on board an update. Apple’s iOS 6.1 update, for instance, delivered an Exchange bug that wrecked havoc on the battery life of iPhones and iPads all over the world. Most of the time though, battery drain is an isolated issue experienced by a minority of users.

From what I can tell, Android 4.4.4 KitKat battery life is the same as it was before with Android 4.4.3 KitKat and Android 4.4.2 KitKat. That is to say average. The Nexus 5’s battery life has never been stellar though fortunately, for me and many others, it has held firm after three Android 4.4 KitKat upgrades.

I’m still getting sporadic battery life. One day I’ll be able to go almost a full day with the Nexus 5, another I’ll lose a few hours for unexplained reasons. This has been consistent since I bought the phone back in November.

I’ve seen complaints about Android 4.4.4 KitKat battery life but the complaints aren’t loud enough to warrant an immediate response from Google. That is to say, I doubt an Android 4.4.5 KitKat update is around the corner. Instead, Nexus 5 users that are dealing with issues, and there are a few, will have to make do with the information that we have.

Battery life problems can often be caused by applications. In order to isolate third-party apps, boot the device into safe mode. This will turn off third-party applications and allow you to better diagnose the problem.

To boot into safe mode, follow these steps:

  1. Make sure the Nexus 5 screen is on and then press and hold the Power button.
  2. Touch and hold the Power off option in the box that pops up.
  3. Tap OK in the following dialog to run safe mode.

If that doesn’t work, check out our Nexus 5 battery life tips. If none of that works, it might be worth performing a factory reset on the Nexus 5 to see if it will dislodge the issue.

The Android L update brings enhanced battery life to the Nexus 5 so if you’re alright with installing a piece of software that’s in the beta processor, you can check out the Android L developer preview and see if that helps.


I’ve scoured through this update, going into the deep dark reaches of Google’s software. And believe it or not, I’ve only discovered one annoying “bug” that seems to have emerged after Android 4.4.4 KitKat’s arrival.

Nexus 5 side

For reasons that remain unexplained, my Nexus 5 seems to be charging slower than usual. Could be a USB issue, could be the power source, could be the phone itself, I’m not sure. What I am sure of though is that it didn’t used to take three to four hours to get to 40% charge. That’s ridiculous and reminds me of my problems with the Nexus 7.


Connectivity remains solid. Bluetooth and Wi-Fi are both performing well. I have heard about Bluetooth and Wi-Fi issues though. While I don’t have a permanent fix for these, I can help point you in the right direction. If you’re suffering from Wi-Fi problems, check out this thread. There appears to be a solid fix in here that should only require a couple of minutes of your time.

Remember, mileage is going to vary given that most of us use different routers with different firmware and connect our devices to different Bluetooth devices with different firmware.


In a word, Android 4.4.4 KitKat is fast. I haven’t noticed any significant lag since I installed it two weeks ago. Simply put, it’s as fluid and functional as it has ever been.

I’ve heard about keyboard lag with the Nexus 5 but I haven’t experienced it myself. If you are experiencing keyboard lag, it might be worth installing the Android L keyboard to see if that helps.

Should You Install Android 4.4.4 KitKat for Nexus 5?

At this point, the only qualm I have with Android 4.4.4 KitKat is the slow charging. And even then, I’m still not convinced that it’s an Android 4.4.4 KitKat or a Nexus 5 problem.


I will say that I hasn’t experiencing too many issues before the arrival of Android 4.4.3 and Android 4.4.4 KitKat so they weren’t huge updates for me but they should serve as big time updates for other people. There is no disputing that Android 4.4.4 KitKat is chock full of bug fixes.

If you’re experiencing Nexus 5 problems with Android 4.4.2 KitKat, this is update is worth your time and it should serve as a good bridge to the next Android update, Android L.
