How to replace Google Pixel 3 XL Battery [Tutorial]

The problem with water-resistant smartphones like your new Google Pixel 3 XL is that they have non-removable batteries. As we know, batteries are among the first ones to deteriorate after months of use and there would come a time when your device just stops charging and would no longer turn on. When it happens, you would need to bring the device to the shop so that a technician can replace the battery for you.

Gone are the days when you simply have to buy a battery pack, remove the damaged battery from your phone and replace it with the new one. You couldn’t also buy a spare battery, fully-charge it and bring it with you anywhere as a reserved power source in case you’re on the go and your device runs out of juice. But then again, these conveniences are replaced with protection for your phone so we really can’t complain about them.

How to Replace Google Pixel 3 XL Battery

Google Pixel 3 XL’s battery can be replaced but you have to open up your phone to do so. That is the purpose of this post. I will walk you through in replacing your phone’s battery and depending on your know-how, you may be able to do it easily. But before that, here are the things you may need…

  • Suction cup
  • Prying tools
  • Screwdriver
  • Heat gun or hair dryer
  • OEM battery for Google Pixel 3 XL

Carefully removing Google Pixel 3 XL back cover

You’ll be spending more time removing the back cover than replacing the battery. It’s because the back cover is the primary protection of your phone and it’s securely glued onto the chassis so you really need to be careful in removing it.

  1. Using the heat gun, heat up the edges of the back cover until it would be uncomfortable to touch it. Just apply enough heat to loosen the adhesive and remember that applying too much heat may damage the battery. And when applying heat, do not point the gun in one place, always move around the edges.
  2. Once the cover is hot enough, put the suction cup on the lower part of the phone or where the USB port is.
  3. Gently lift the suction cup until you can see a slight opening between the back cover and the frame. After applying reasonable amount of upwards pressure, the back cover should separate slightly from the frame but if it doesn’t, you may need to apply more heat.
  4. Place a prying tool into the crack to prevent the glue from sticking back to the frame.
  5. Move the prying tool along the sides to loosen the adhesive but be very gentle in doing this so as not to mess up some components. Also, don’t push the prying tool too deep. You may use more prying tools if necessary. If the phone cools down before the back cover is removed, try applying heat again to loosen up the adhesives.
  6. Once the back cover is loose enough, lift it gently so as not to break the flex cable of the fingerprint scanner.
  7. The fingerprint scanner flex cable is secured by a bracket and a couple of screws. Remove the screws to remove the back cover and you can disconnect the flex cable after that.
  8. Once the flex cable of the fingerprint sensor is removed, the back cover is detached from the phone. You may now begin removing modules you want replaced.

Removing and replacing Google Pixel 3 XL battery

Once you’ve successfully removed the back cover, you will have access to every component inside. Follow these steps to replace the Google Pixel 3 XL battery of your phone…

  1. Remove the bracket at the side of the phone that’s secured with a couple of screws to access the battery connector and the wireless charging flex cable.
  2. Remove the wireless charging module and then proceed.
  3. Once you’ve successfully removed the back cover and disconnected the flex cable of the fingerprint sensor and a couple more components, then replacing the battery would be a breeze but first, disconnect the battery from the motherboard. It’s connected via a flex cable that you can easily disconnect using a prying tool or a pair of tweezers.
  4. Gently remove the gold strip at the side of the battery and this should also make the battery loose from the compartment. Again, the adhesive that secures the battery isn’t that strong so you shouldn’t have issues removing it.
  5. Once the battery is removed, replace it with a new battery, which should fit well into the compartment.
  6. Connect the new battery’s flex cable to the motherboard.
  7. Once connected, try connecting the phone to its charger to see if it charges and if it does, then the replacement is working properly.
  8. Reconnect the wireless charging coil and then secure them with the long bracket.
  9. Reconnect the flex cable of the fingerprint sensor and then secure it with the back cover.
