Step 1

Heat the back cover of your Xperia Z3 to loosen the adhesive underneath.
If you use an iOpener, follow these instructions for use.
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.
Don't put the pick in too deep under the back cover to not damage any parts inside the phone.

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!

Step 2

There are two adhesive strips in the center of the phone connecting the rear case to the battery, you'll need to remove them to open 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.

Step 3

Gently pull out both of the adhesive tabs out of the phone, parallel to the rear cover.
If the adhesive tabs break, try to use a thin flat plastic tool such as a plastic card to remove the last of the adhesive. If the adhesive is stubborn, heat it with an iOpener or hair dryer and pry again.
