Upgrading Nexus 4 from Android 5.0 to 5.0.1 (spoiler alert: no problems)

The big step was the upgrade from Android 4.4.x to 5.0 but there was a surprise today, the Nexus 4 had a surprise persistent-notification, Android 5.0.1 was here and ready to be installed. To cut a long story short, this was a very smooth update.


This update took about 25 minutes wall clock time. The actual time may vary depending on how many apps you have installed. My count this time was over 120! The update itself is just 16.7MB. But it still goes through the whole song and dance, it’s not just a quick patch.

Interestingly, I attempted to do this while on AC power with just 14% power left on the battery, and it wouldn’t let me start until there was enough juice on the phone. Even though it was connected to the wall power.

So here is a play-by-play of the update:

  1. Download, then “Restart & Install”
  2. “Installing System Update” with the green Android’s belly being “worked on’ and the two green antennae moving around (around 5 minutes)
  3. then reboot, Google Logo appears, then the four colorful balls bouncing around nuclear-physics style (about 3 minutes)
  4. now we got the app optimization part, “Android is Upgrading” (about 15 minutes)
  5. then “Starting Apps” (about 2 minutes)
  6. and we are ready to go!

Lollipop and Nexus 4 Battery Life miracle?
It is too early to tell for certain, partially because the Android OS was “doing things” in the background, perhaps in preparation for this update, but while on 5.0, and after the latest flurry of activity ended, I was about to get two full days on a single battery charge, without Battery Saver and without Airplane mode. If Lollipop is able to do that, it is nothing short of a miracle! I will pay attention to it after version 5.0.1 is settled in!

That, plus the benefit of the Battery Saver mode (which I am experimenting + tempted to leave it on all the time) could be huge battery savers!
