Use this guide to replace your phone's battery, In this example, we are using an iPhone 6.
Note: It's extremely important that each screw is put back into its correct place. If you mix up screws, it's better to proceed with the battery replacement without them. If you put the wrong screw in the wrong hole, it can damage the phone's logic board
- Turn off your iPhone 6 and unscrew the two pentalobe bottom screws next to the charging port.
- Separate the screen from the back housing. Begin by pulling the screen carefully up with the suction cup.
- Once there's a tiny hole between the front and the back, insert the plastic pry tool or spudger. Move the tool along the side of the phone to fully separate the front assembly.
- Lift the front assembly to a 90 degree angle.
Step 2 - Disconnecting the Battery
- Unscrew the metal plate on top of the battery connector and remove the metal plate with you fingers or the tweezers.
- Disconnect the battery's connector underneath the plate with a plastic tool. The connector will come loose easily with very little force.
- Disconnect the LCD, touch, front camera/sensor and home button connectors with a plastic tool, just like you disconnected the battery connector in the previous step.
Step 4 - Removing the Battery
There are a few ways to proceed with the battery removal:
- The battery is held in place with two strips of STRONG adhesive. These adhesive strips can be pulled out from underneath the phone. If they tear, the battery will have to be pried/levered out (see 1st and 5th picture) from the LEFT side of the phone (NOT against the logic board). You can heat the back side of the phone with a hair dryer to soften the adhesive, the battery will come out easier this way.
- Once the adhesive is out, the battery can be removed with your fingers.
- Put new adhesive in place and put the battery on top of it. Put the loop of tape in the same place where the old adhesive was and press the battery down with your fingers.
- Reconnect the front assembly if you disconnected it previously.
- Connect the battery's connector by pressing it down with your index finger and screw the metal plate fasten. At this point you could try to turn on the phone to make sure everything works normally. If something is not right, you can easily make adjustments without having to open up your phone again.
Step 6 - Put the Front Assembly Back in Place
- Lower the front assembly to the back assembly. Make sure the top of the front is adjacent to the top of the back assembly. Press the two assemblies together with your fingers.
- Screw the bottom screws fasten.
- After a battery replacement, the phone's time and date is rolled back to default. You will need to sync your phone with a wifi-network to automatically adjust the time and date before it finds reception, otherwise it will just say "Searching..." in the top left corner of the screen.
