Nexus 7 on Android 4.2.2 has 10 hours of battery life instead of 8

by: Chris SmithFebruary 13, 2013


Android 4.2.2 is upon us, which means that most Nexus devices out there can be upgraded to the latest mobile OS version released by Google.

But a day after the Android 4.2.2 roll out, Android Police noticed something interesting with the Nexus 7 product pages. Google has updated the them to reflect better battery life for the device, with the Nexus 7 now capable to offer “up to 10 hours of active user” instead of the previous eight hours.

At the same time, we shouldn’t be surprised to see Google try to improve battery life, as this one seems to be one of the concerns that need to be addressed in future devices, at least according to Larry Page (although he was talking about future Motorola future handsets). What better way to start than by optimizing software?


We’re definitely waiting for more feedback from Nexus 7 owners that already rock Android 4.2.2 under the hood. Are you experiencing a longer battery life than before? Have you noticed battery life improvements on any other Nexus devices?

    If the battery life of the nexus 7 is really updated to 10 hours; it would be really great

  • The original docs said 10 hours of e-reading so nothing has changed. The original docs also said 8 hours of doing this and 9 hours of doing that. You can still get up to 10 hours. They are just clarifying, the same as the competition does.

    I have just searched for information on a battery optimisation for Nexus 4 on 4.2.2. I have a noticeable extension of battery life since the upgrade. Why no mention officially though?
