How to replace SONY Xperia Z/ZL battery in under 10 minutes !

Translation: “If you want something done right, Do It Yourself.

Disclaimer: This is my DIY method to disassemble the SONY Xperia Z or ZL and replace the battery in under 10 minutes. While I have simplified much of the process in order to make it idiot proof, it is still not 100% idiot proof.

So, if you still feel that you aren’t confident enough to tackle whatever issue you’re facing with the phone by yourself; it would be much more advisable and safer to go to a professional or have it fixed at a SONY showroom. Safety first !

Alright then, lets get started.

What you’ll need :

1. A SONY Xperia phone ! (One that needs some fixing I’m assuming. If it’s perfectly alright, I don’t know why you’re still reading this. =P )
Black SONY Xperia ZL

2. Tools for the job !

Army knife, tool kit, laser pointer, scissors.

What I thought I needed.

Just kidding !  =D
You don’t need much. I managed everything with a cross pointed screwdriver, a guitar pick and a thin flat blade screwdriver which I used only for prying open stuff.

3. 10 minutes of patience and of-course a new battery. If this is your first attempt at opening up a phone, it might feel a little nerve wrecking but I assure you it’s a piece of cake.

Method:
Step 1:  In order to access the battery we will have to open it up backwards ( Screen should be facing down) starting with the cover, then the motherboard and  finally you will see it.

Step 2: On the bottom of the back cover, you should see a small flap. This is where the Sim card and the memory card of the phone fit into place. Now lift the flap upwards. You will see a small sticker which you have to peel. After peeling it you will now have access to the 2 screws (size Phillips #0)  that hold the cover together. Unscrew them with the screwdriver and keep them in a safe place. You will need them later on.

Step 3: Now taking your guitar pick/ thinnest available object that can be used for prying, gently insert it between the back cover and the frame of the phone. Once inserted deep enough into the gap, you can now slowly slide it along the phone. This will separate the 5 clips, 3 of which are on 1 side while the remaining 2 are on the other. You may hear the glue cracking and some clicking noises as the cover comes off.

Step 4: Highlighted in blue are the ribbon cables which are connected to the motherboard ( the greenish circuit thing). In order to disconnect them you just have to gently lift them off as they have snap at the ends. No biggie. Lift them up with a screwdriver or any thin flat object. Just make sure to not use excessive force as they are quite delicate. The battery cable  which is the tiny wire at the bottom right corner highlighted in yellow, might need a little extra force though.

Step 5: Next we will have to lift the thin rubbery black piece which is called the NFC antenna. On doing so you will see a small copper tape (highlighted in purple) which bridges the connector & the motherboard. Peel this tape upwards.

Step 6: Now we will have to remove a few more screws.

Unscrew the 2 screws near the charging dock on the top right of the phone( highlighted in Red). On doing so, you will see a tiny metal bracket (Highlighted in Blue). Lift the bracket from the Left side, the side closer to the circuit board.

Next, we have to remove the 2 screws on the left of the motherboard.  I would suggest removing the lower one first which is highlighted in red and then higher one highlighted in yellow. But hey, to each his/her own. The last and final screw is at the bottom right of the motherboard. Remove this one also.

Step 7: Towards the top of the phone is the camera & speaker module. We will need to remove this part as well. A word of caution though: This step could be considered moderately difficult and requires extra precision & delicacy as the flex cable is really fragile and will tear easily upon even a slight amount of force.  Do not fear but don’t take it too lightly though. If it does tear your phone will still work fine, although you will surely have issues when it comes to connecting your headphones. You will have to lift the connector at a 90 degree angle to slowly separate it from the adhesive. Since it only encompasses a small square area, it can be quite a bother but I assure you it isn’t impossible. Take your time with this one.

Step 8: Almost there! Now we can go ahead and start removing the motherboard. Insert your prying tool behind the motherboard from the Left side . Now carefully lift the board to a 45 degree angle but make sure that No ribbon cables are still attached ! Otherwise you might cause them to rip so double check just in case.

Step 9: Voila! We can finally see the battery! On the bottom of it you will notice a copper inducting tape. You will need to bend the ends of the tape and then slowly but firmly, lift it off the battery. Do not throw it away as you will have to slap it back on your new battery after replacing!

Step 10: Now we can remove the battery. Use your prying tool ( I used my guitar pick again) and slowly wedge it in between the back of the battery and the case, making your way all around it. Note: The glue holding the back of the battery is very strong, so this step might take you a while. Be careful whilst removing the old lithium ion battery and try not to damage it as much as you can. Once it comes out, discard it and attach the copper wire to the bottom of your newly installed battery.

Step 11: There you go! You did it! ( I hope) =P

Right now you must feel like you climbed all the way up to the summit of Mt.Everest. As far as re- assembling it goes, simply consider this analogy: Getting to the top of the mountain is only half the journey. You now have to climb your way safely down! How else will you go on bragging about your new accomplishment for a life time?

In the same way, you must now assemble your phone back by yourself, so you too can brag about your experience of fixing it in under 10 minutes ! Don’t worry, by now you have got the feel of the phone and are experienced enough to finish the task.

Good Luck!  =)

Eureka! It works !

  1. Thanks for the tutorial. The only thing I screwed up was the notification light on the bottom. Do you know which connector I have to look for? Thank you anyway!

      1. It doesn’t work at all. Not even charging, getting any type of alert (msjs, mails, etc), or calling somone. No lights, any color.
        I’ve tried marking *#*#7378423#*#* to use the notification test, but it didn’t help neither.
        I guess it’s a hardware problem.
