iPhone 4 Battery Replacement – You Can Do It!

June, 2013

After two and a half years, my iPhone 4 battery suddenly would not hold a charge longer than a few hours.  Since I was used to it lasting all day, or close to it, this caused me problems.  I haven’t felt a need to upgrade to either the iPhone 4S or the iPhone 5, so I searched for information on replacing the battery to assess how much of a hassle it would be.

I have to admit I’m quite surprised at how easy it turned out to be.  I’ll get directly to my path to battery happiness:

1. Watch this YouTube video on “How to Easily Replace an iPhone 4 Battery” by HighT3chDad.

2. Order a replacement battery.  I ordered this one on Amazon for only $7.05 with free shipping through Amazon Prime (currently only $4.99 + $0.99 shipping), and it included the tools along with the battery.  “Genuine Iphone 4 16G 32G Battery 3.7V 1420mAh and Tool”

3. Set aside 30 minutes to review the video, and replace the battery.
Really!  It’s that easy.  I’m very happy to have a new battery and not have the hassles of upgrading my phone!


p.s. This post is a bit after the fact, and the replacement battery has performed well for the past year and a half.  With the iPhone 6 having just been announced, I’m likely to upgrade soon, but I’ll probably keep my iPhone 4 as a development device, so for anyone still hanging onto a iPhone 4, don’t be afraid to replace that battery!

I didn’t just go shopping for buttons, bigger buttons, “EASY” buttons, buttons to press, buttons to buzz and buttons that light up… for no reason.   And I didn’t put out the shopping searches because I have a “thing” for buttons.  It started last century when Mrs. Project needed a “first to respond” device for a summer camp.

I enthusiastically rose to the challenge and made a quick trip to the library to look up a “lock out,” or “first to respond” circuit.  Sure enough, Graf’s “Encyclopedia of Electronic Circuits, Vol 6.” came to the rescue with an ideal SCR (Silicone Controlled Rectifier) design that was perfect for the task. Radio Shack with project saving inventory, and several project boxes, buttons, lights, (not LEDs!) a power supply, and “ta daaa!”  The rugged device has worked well all  these years.

It happened that a new camp director wanted their ownlock out” device, and the notion that I’ve wanted to do an Arduino project just bubbled out of my brain, through my mouth, and out of my lips as I said, “no problem, we’ll make a new one.”

That’s how I came to start typing in “buttons” in the search engines.  I also found out my search terms were out of date, and better hits happened with “Jeopardy,” and “Quiz Game.” I found these buttons and really liked them for the new “Quiz Game Controller.”

We think you might like them also, or at least be curious about them.  Check out our written review and our video review to get a feeling for how they work.

May your projects go smoothly,
