I have done quite a few installs and hardware replacements in my time, but never have I found an easier project than to replace the battery of an iPhone 4. As with many of my previous iPhones, I tend to blow through the batteries pretty quickly. Some of the signs that you have an aging battery are:
- battery drains faster than normal
- battery charges faster than normal
- sometimes have crashes or other OS issues
In both those cases, the battery is not storing as much of a charge as previously, so it will discharge faster and consequently it doesn’t take as much to charge up. Once my iPhone 4 started manifesting these characteristics, I knew it was time to replace the battery.
As with most of my repairs that I embark on, I always look for a source to help explain the process. In most cases, I look to iFixIt.com and their parts and guides for repairs. You can see some other iFixIt and similar repairs that I have used in the past.
So for the iPhone 4 battery replacement, a quick scan of the replacement process showed me that it was actually pretty darn easy. Here are the things that you need for the battery replacement:
- The iPhone 4 Battery Replacement iFixIt Guide
- #00 Philips screwdriver
- Plastic opening tool or spudger
- Pentalobe screwdriver (if your iPhone has pentalobe screws instead of phillips)
- Egg carton or something similar (to hold screws)
- iPhone 4 Replacement Battery
I recommend watching videos of the process as well as reading through the guide carefully before you do anything. Below is the video of me replacing the iPhone 4 battery (direct link to YouTube):

Most of the details of the removal and installation process are in the video. However, I did snap a few photos along the way.
Here’s what my setup looked like (I didn’t use all of the tools shown below):
Here are the tools that I actually used in this process:
At the bottom of the iPhone are the two screws that you use to open the back. You can see what type of screws you have, either #00 Phillips or the new Pentalobe (mine had Phillips):
These are the tiny #00 phillips screws in an egg carton:
Once you slide the back open, you will see the batter. Be careful when taking off the second screw as there are other small tabs that are attached to it:

In the design of the iPhone 4, Apple has made is much easier for people to replace the battery, whether they be Apple technicians or Apple product owners. Having done this install process just one time, I can comfortably say that this is probably the easiest and fastest fix/install that I have done. But, for those people who haven’t done this type of thing before, I recommend the following:
- Go slowly
- Don’t drink a bunch of coffee before (trembling hands don’t work well with tiny screws)
- Read the install guides
- Watch some video of people doing this (like mine above)
- Remain calm
- Don’t panic
It always makes you feel good when you can do these types of repairs yourself and you aren’t paying someone else a premium doing something that you can just as well do. Also, with the next version of the iPhone (iPhone 5?) right around the corner, you might want to get your iPhone 4 fixed up in case you want to sell it or give it to someone (like your children). If you kept your iPhone 4 in a case, it should be in pretty decent shape. Putting in a new battery will bring it back to being practically new!
