Introduction

Users of this guide will be able to remove the connections from the motherboard to gain access to their battery. This repair is much more difficult compared to other phones' battery replacements. Be careful not to damage any other components during the repair.

Insert a microSD card eject tool or a paperclip into the small hole in the microSD card tray, located on the upper right hand side of the phone above the volume buttons. Press to eject the tray. This may require a significant amount of force.

  • Press to eject the tray.

    • This may require a significant amount of force.

  • When reinserting the microSD card, ensure that it is in the proper orientation relative to the tray. The contacts should be inserted first and face to rear side.

  • It is normal, that the microSD card doesn't stay on it own inside the tray. It is also not completely trivial to place it correctly flat inside the tray.

Be sure to remove the SIM tray and memory card tray prior to removing back case! Bent mine because that step was missing.

The black plastic piece that runs across the top is very thin and is stuck on with very strong tape.

Work a plastic opening pick around the perimeter of the device to separate the rear case from the display assembly. The SIM card tray and Micro SD card tray must be removed before the back cover can be removed. Be careful around the power and volume buttons, as they are fairly delicate.

  • Be careful when separating the body from the display assembly, as the rear-facing camera may be stuck to the body with adhesive.

The SIM Card and SD Card's need to be removed before the case will come apart.

Disconnect the remaining three ZIF connectors. The third ZIF connector is mostly underneath the motherboard. When reassembling your device, make sure it is placed back underneath.

Great guide just one crucial warning missing! When removing the battery which is underneath the power/SD/volume cable make sure you see that and carefully remove the battery without tearing it apart! Had to learn the hard way. Fortunately it's replaceable..

    • The motherboard is secured with adhesive, so you may need to use an iOpener or heatgun to loosen the adhesive. Refer to the iOpener guide for info on this.

Mine did not have any adhesive.

I replaced the battery now but encountered a problem, as my phone wasn't working properly afterwards. When I switched on, it kind of reset to default and the play store app kept crashing, so I had to do a factory reset

Removal went as directed, about to attempt in reverse! Wish me luck

Done all of this by the book but phone won't turn on charge screen lights up and charges but still won't turn on please help

You tore the power and volume button cable. It's a $10 replacement, no big deal. I did the same thing even after having repaired phones for years now.

For me works everything except touch screen :/ i dont know what i done wrong... screen works good, but can't touch it

Those snap on antenna connectors are the hardest part of this job. Really hard to line up to reconnect them. I was initially sent a bad battery, so I had to go through the whole process again with a good battery the second time, and it worked just fine. I would not want to make another attempt with those antenna connections though. I think they're easy to distort, and not made for frequent disconnects and reconnects.

I would say explicitly to disconnect the battery connector since i did not and saw some magic sparks frying one of the connectors of the motherboard

Cool, success! I'm a bit OCD when it comes to my electronic repairs/assemblies. With these phones these days, we could've powered the moon landing...from a mobile pc that fits in our hands...so needless to say, it's a fight for space (no pun intended, but I laughed later) inside the cases, so batteries being a huge consumer of ever diminishing space, I'm surprised we can even get these out at all!

Un bon tuto pour le changement de batterie. Je rajouterai juste une chose, les nappes ne sont pas faciles à remettre, il faut bien faire attention et faire un test d’allumage avant de refermer le téléphone !!!

Successfully replaced my battery. After restarting my phone the vibration was super loud as the motor was loose in its seat. I had to stick a piece of double sided tape above the vibration motor to help sandwich it into place when the back cover was fitted. Working fine now.
