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.

Pixel 4 Battery Case

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 4 XL Battery Case

ZeroLemon is a company known for packing in massive batteries in phone cases. This Google Pixel 4 XL battery case from ZeroLemon has a huge 8000mAh battery. That’s more than twice as large as the battery included in the Pixel 4 XL. This should extend the battery life of your Pixel 4 XL by 140%.

The case is made of soft TPU material which makes it easy to put on and remove. Unlike the ZeroLemon case for the Pixel XL this one does not have a chin at the bottom.

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.

If you don’t use wireless charging though, the case does make up for it in thickness. This battery case for the Google Pixel 3 XL is only 0.16-inch thick.

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. As with the other Newdery cases, it features slightly raised lips o protect the screen and camera from scratches. Unfortunately, this one does not support wireless charging either.

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.

The Pixel 2 battery case provides 360-degree protection with raised lips around the screen and camera. The frame has cushions, the outer-shell is rugged and is designed to resist slipping. It also supports data transfer which can’t be said for most other cases on this list.

Bonus: Portable USB C Battery Charger Pack

This one is not exactly a battery case but a portable battery pack. So it can still be used to extend the battery life of your phone.

That makes it a little easier to charge your phone when you’re moving around.

There’s a 4500mAh battery inside which should charge your phone from 0 to 100 at least once. Since this is a USB C charger it can attach to any device. This includes non-Pixel phones as well as everything from the Pixel 2 to the Pixel 4.

Pros:

  • Compatible with any smartphone with USB Type C charging port
  • Easy to carry
  • Available in different colors

Cons:

  • Looks ridiculous while using the phone with the charger attached

Key Features:

  • 4500mAh battery
  • The small size makes it very portable
  • LED indicators

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.
