Last year’s Google Pixel 3 really suffered in the battery life department due to a smaller battery. Therefore, it was surprising to see Google launch the Pixel 4 with an even smaller battery and a 90Hz display. As expected, Pixel 4 is no battery champ. Neither was the Pixel 3. Even the Pixel 2 and the original Pixel were only decent when it came to battery life. So if you have a Pixel, picking up a Google Pixel battery case to extend battery life is a good idea.
Here’s a list of the best battery cases for Google Pixel phones that you can find on Amazon. This includes battery cases for the original Google Pixel, Pixel 2, Pixel 3, Pixel 4 and all their XL versions.

The case adds almost 150% of extra battery juice to your Pixel 4. The Newdery Pixel 4 Battery Case also has raised bezels in the front to protect the screen.

Google Pixel 3 XL Battery Case
This Google Pixel 3 XL battery case claims to extend the battery life by about 90%. It features a 4700mAh battery with no support for wireless charging. What’s bad is that the Pixel 3 XL does support wireless charging. So if you have a wireless charger you’ll need to take the case off every time you intend to use the feature.

Since the case is smaller in size and still had to fit the same 4700mAh battery, it’s a bit thicker. This Google Pixel 3 battery case will add an extra 0.43-inch to your phone.

But it’s slimmer than most other battery cases. For that, you get a relatively smaller 3900mAh battery. That’s about 1.5 times the size of the battery on the Google Pixel 2.

Google doesn’t make a smart battery case for the Pixel like Apple does for its iPhone. So the charging does not kick in automatically in either of these third-party battery cases. And neither does it turn off on its own. These battery cases have a power button on the back that you can use to turn on or turn off the charging anytime you want.
