Introduction
Use this guide to replace the old battery in your Sony Xperia Z3.
What you need
-
-
Heat the back cover of your Xperia Z3 to loosen the adhesive underneath.
-
Lift up the back cover with a suction handle and put an opening pick in the gap.
-
Move the pick carefully around the edges to loosen the adhesive on every side of the phone.
-
-
-
When the edges of the cover are free from adhesive, tilt it to allow access to the battery tabs.
-
Use tweezers to pull the two black adhesive strips out of the phone but don't pull just yet.
Careful during this bit. My old Z3 back cover couldn’t take it and split into lots of pieces (probably weakened over the years!). Just order a replacement for £3 off ebay before doing it ;-)
Merci pour ce tuto. Excellente procédure. Travaux réalisés en 20 minutes sans aucun problème. Attention: au remontage, il n'y a plus d'adhésif sur la batterie, la coque arrière peut éventuellement tomber. Je ne l'ai pas fait mais il faut peut-être mettre un petit double face sur la batterie.

En hoe krijg je ‘m dan weer goed dicht?
If the original tape won’t hold anymore, you could replace it with double sided adhesive tape to reseal the back cover. Take a look here:
or directly in the EU Store for shipping to the Netherlands:
When I opened up my phone to replace the battery, almost everything in this guide was still correct except that now the battery is screwed in with 1.2mm star screws.
This guide worked for me.
But during step 3, the tabs ripped off, and I had a hard time separating the battery from the back cover.
So instead I used a tweezer to disconnect the battery (step 5), and slowly pried the battery off, along with the back cover. After that, you can have more space to work with removing the battery from the cover.
Great guide, worked a treat.
Z3 lives again!!
Love this site and all it stands for,
Many thanks : )
How hot (how many C) should the iOpener be? I think it would be safer / more accurate to heat the iOpener in an oven with accurate temperature control.

Careful here. The back cover cracked in two places. Once when I exerted pressure with the suction handle, and in the corner when moving the pick around the edges- even though I was very gentle. The battery was adhered firmly to the back cover.

I cracked the back cover instantly. Make sure to buy a spare one before opening!
