How To Replace An iPhone 6 Battery

Here’s a full guide to replacing the battery in an iPhone 6. This works for batteries which have failed due to overcharging, through over use or those which have just swollen up over time, like the one in the video. You can save a lot of money by doing this easy and relatively quick repair at home by buying your own inexpensive replacement parts and tools, linked to below. The replacement battery costs between $10 and $20 and you can get the toolkit for a further $5 to $15.

If you’ve shattered you iPhone screen, here’s our guide to replacing the screen on an iPhone 6 or 6s.

How To Replace Your iPhone Battery

Find yourself a nice, flat desk or counter to work on as you’ll need a bit of space to lay out the components as you take them out. Make sure to keep track of each screw as you’re taking them out as they are different lengths and sizes and you don’t want to damage components by putting long screws in the wrong place. It helps to draw a small sketch of the components and place each screw on the sketch as you remove them, this way you’ll always remember which one goes where.

The battery is held in place with a really strong double sided tape. Gently heating up the back of the iPhone case with a hair dryer or heater softens the adhesive a bit and makes it easier to remove. Be careful not to damage any of the ribbon cables for the side buttons near the top of the phone when you are prying underneath the battery.

Good luck and enjoy the repair. If you found this video helpful, please like it and subscribe to my channel for more tech videos.

  1. Hi, used this excellent guide to change the battery in my 6S today.
    I would recommend having some fire-safety precautions mentioned in the video.
    When prising the battery off the case, even though I had heated it to soften the tape, the battery distorted and I think it started to smoke for a second or two. I didn’t have gloves or sand/water to hand and if it had caught fire I would have been in trouble!

    Otherwise very clear and useful video.

    • Thanks for the great feedback Neil. Will keep that in mind for future videos, it’s a good idea to take precautions just in case.
