Introduction
Use this guide to replace the Moto G4’s rechargeable battery. If your battery is swollen, take appropriate precautions.
Before you begin, download the Rescue and Smart Assistant app to backup your device and diagnose whether your problem is software or hardware related.
For your safety, discharge your existing battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
What you need
-
-
Insert a fingernail or a spudger into the notch on the bottom edge of the phone, near the charge port.
-
Gently twist or pry to open a small gap between the back cover and the body of the phone.
-
While keeping your tool (or fingernail) inserted into the gap between the back cover and the body of the phone, slide it around the corner to begin loosening the plastic clips holding the cover in place.

Use a T3 Torx driver to remove the nineteen identical 3.1 mm screws securing the midframe.
In my kit, the T3 Torx bit came in the ‘repair part’ box, while a T5 Torx bit was in the ‘repair tools’ box.
my phone had t4, not t3
unable to remove 8 of the screws. any suggestions?
My T4 is the tool that fit. I can see why people strip these. They were dam tight for such little screws.
I also had a tough time getting them out of the socket once loose. Magnet in the tool was not very strong. I used my tweezers, and scratch the screw heads. That means they are real soft steel, and strip easy.

-
Insert a spudger under the midframe at the top left corner, and gently twist to separate it from the body of the phone.
-
-
-
Remove the midframe.
During the midframe removal, be careful and do not put too much torsional stress on the loudspeaker pickup wires (to the right of the main camera). It’s not that difficult to crush or shear the pickups there. Doing so will render your phone silent.
Exactly what happened to me. Both contacts broke off and if just loosely put where they were, they can't make proper contact anymore.
There should be a warning about this in the guide itself!

-
Insert a thin tool (such as one of your tweezer tips) under the red and black battery wires, and slide it underneath the battery connector.
-
Gently pry straight up to disconnect the battery.
Before detaching the connector, you may want to take a photo to remember which way the red and black wires go. Mine were the same way as in this photo, but when looking at the tiny connector of the replacement battery it wasn’t easy to be sure which way to insert it.
What can you do if you break the socket??? Will anyone email me an idea, Or- is it simply ruined-??? My email address is jeffrey_f4@yahoo.com. THANKS in advance, IF- anyone will take the time to email me about this-!!!!!!!! :)
So you have bare copper wires and you’re sticking a metal tip tweezer in the vicinity.
And yes, the battery is discharged as far as you can, but,………
Maybe an idea to snip the wires somewhere further up before doing this ?

Bought the battery from Ifixit because I’ve enjoyed your videos. I changed the battery, all seemed well, but now I get no sound out of the speakers! They are not mentioned on any of the topics. Help!?
See the comment on this step. Make sure the two little copper prongs on the back of the speaker make good contact with their respective pads on the back of the midframe. It’s okay to (very gently) bend them up slightly if needed.
bought battery and kit from ifixit. replacement went pretty well. Careful with those tiny little screws. They do not like to come out after loosening. I worked over a small tray and still had two get away from me. I also had some tape on the sim card side of battery not mentioned in instructions. I tore it pulling it back. Was concerned as it seemed to be foil faced on back side which sepperated when pulling up. All works though so no worries.
Bonjour,
Etes-vous sûr pour le modèle du tournevis ?
J’ai échoué avec le Torx T3, mais réussi avec le Torx T4
It definitely should be a T3, but not all driver kits are created equal. If a T4 works better for you, go with that ;)
Def T3, it’s the one not in “The Essentials” kit
I encountered two large adhesive pads affixing the battery to the metal frame. A couple drops of IPA weren’t enough. Gentle levering at the camera side of the battery and a slow injection of IPA with a syringe eventually did the trick. Take it slow and let the IPA do its thing.
What is “IPA” , mentioned as a lubricate ?
Lester -
my battery worked fine but after charging the phone the first time it wont turn on it has been plugged in for 12 and a half hours
At end of Moto G4 battery replacement instructions , it says “ After completing this guide, calibrate your newly-installed battery. “
Don’t see any furthur explanation of this reference or how to calibrate ?

Bonjour,
Déjà à la lecture, le tuto est très clair, détaillé. Il met en confiance pour acquérir le kit de réparation. Les illustrations par photo sont très utiles. Un seul tout petit bémol, mais vraiment tout petit à l’étape 13, au remontage, le connecteur de la batterie (qui est vraiment très petit) est quand même assez contre-intuitif. D’un côté on aperçoit 2 petits trous où le cuivre apparaît et de l’autre côté, non. Et c’est ce côté, sans cuivre apparent qu’il faut clipser. J’ai effectué plusieurs tentatives du mauvais côté avant de consulter le tuto et surla photo très claire on voit bien dans quel sens il faut mettre le connecteur.
J’espère que la batterie tiendra mieux…
Merci.
I didn't find your instructions when I first opened the back cover. Followed an instruction on youtube that suggests T4 screwdriver. Now 5 screws were stripped. Can't take them out. Can you post the size of the screws? I may have to drill the screws. Thanks
Hi Ruby,
I’m sorry to hear this! From my experience, there has been quite a bit of variation and manufacturing tolerances with the screws Motorola uses, and as a result, T3 works for some and T4 works for others. I can’t tell you much about these screws other than that they are 3.1 mm long.
