Can you replace your iPhone battery yourself? Yes, and here’s how easy it is

iPhone battery replacement-6

Andrew Hoyle / CNET

When I found one iPhone 6 on eBay for only £ 75 (about $ 1

00 or AU $ 140), I was very happy. But I was less satisfied when I found out that the battery had aged to the point where the software lowered the performance. But instead of throwing away the phone and getting the buyer’s regrets, I decided to buy a replacement battery and tools from iFixit to be able to replace the battery myself.

After an hour of work, I replaced the battery and the iPhone 6 went perfectly again. I’m not giving step-by-step instructions here – go to iFixit and grab a kit if that’s what you’re looking for – but I want to share my experiences, including how easy it was to do, and hopefully answer some of those questions. you can have if you also need a new battery.

Please note that all maintenance on your own devices is entirely at your own risk.

1. Why do you need to replace an iPhone battery?

Batteries age over time, and considering that the iPhone 6 was released six years ago, it was no surprise that the one I bought did not run in top condition. Once, the phone unexpectedly restarted while in use, and it flashed a warning dialog that read: “This iPhone has experienced an unexpected shutdown because the battery could not deliver the required peak power. Performance management has been applied to prevent this from happening again.” and with the phone itself knew it had a battery.

In short, a phone’s performance can be stifled if it no longer meets the power requirements. It is possible to turn off the throttle, but this will result in more frequent crashes. None of the situations are ideal, so a battery change seemed like a smart way forward for me.

2. How much does a replacement iPhone battery cost?

The problem with my situation specifically was that I primarily bought the phone for so little to spend more money on a battery replacement service negated some of the initial savings. Apple’s official replacement service costs £ 49 ($ 49), which is more than half the price of my iPhone 6 I bought. Being in the middle of locking in coronavirus also meant that it is not really an option to come to an Apple store and sending it in via email would cost £ 56.44.

However, iFixit is selling a £ 35 DIY exchange package (including postage to my home in Scotland). It costs $ 30 in the United States and with shipping costs of $ 37.96. It’s not a huge saving over Apple’s official compensation, but every little bit helps.

3. What’s in the iFixit battery pack?

The iFixit kit comes with a third-party replacement battery not from Apple, because Apple does not sell its parts separately. It also has all the tools needed to unlock the phone and remove the old battery. All I needed was a hair dryer to heat up and remove the glue.

4. Does your telephone warranty cancel the replacement of a battery?

Opening an iPhone will void the warranty, but if your battery is so old that it needs to be replaced, it is likely that you are already out of the 12-month warranty period.

5. Is it safe to replace your iPhone battery yourself?

This is not that easy to answer. iFixit’s guide provides very detailed instructions on the steps involved, but there were a few points that made me nervous. One step involved heating the back of the phone with a hair dryer to loosen the glue that holds the old battery in place.

Specifically, it noted that the heat was “slightly too hot to move comfortably”, which I thought was a bit vague. Especially since that section also warned that “overheating the iPhone can ignite the battery.” But how hot is too hot? What signs would I see if it was overheated? I could not find this information and was therefore not so sure how close to overheating I may have been.

Shortly after, when I tried to pry out the old battery, I accidentally ripped into what looked like the black that wrapped around that battery. I was pretty sure that the battery itself was not punctured – there was no smoke or hissing – but I would have felt much more comfortable if I had “emergency” instructions on what to do if the battery turns on.

Can I replace my iPhone battery myself?

Up to a point, yes, and I’m not normally “practical” in a DIY sentence. iFixit’s instructions were easy to follow and there were only seven internal screws to remove, which were easy to replace.

What I found a little confusing was that the iFixit instructions on the website ended at the point where you remove the old battery. The only instruction in the conclusion was to follow the previous steps in reverse order. Admittedly, it was not very difficult to do, but I would have appreciated more guidance at that time.

One issue I came across independently of iFixit was that I removed the screen protector that was in place when I removed the screen. I noticed that the hairline was cracking and was worried that I had damaged the screen, but thankfully it was undamaged.

7. Is it worth replacing an iPhone battery?

It really depends on the age and value of the phone. If you, like me, bought a cheap used iPhone and just want to get it faster, it’s a great way to breathe new life into old technology without spending a fortune. But remember that this would not be my headphone, nor did I buy it with my own money. For me, the risk was low and if I had done it wrong and destroyed the phone, it would not have been a big problem. You need to consider whether you can really do without it, if the worst happens.

If you are using a newer device, such as an iPhone X ($ 900 on Boost Mobile)for example, I would probably just take it directly to Apple. The savings you get by doing it yourself are not so great that it justifies the potential cost of damaging a more valuable phone.
