DIY iPhone Battery Replacement: This is when we tried it.


Andrew Hoyle / CNET

I’m glad to see an old one. IPhone 6 On eBay for only £ 75 (approximately $ 100 or AU $ 140). That was a huge savings on a new iPhone and as it still runs the latest iOS 15 I knew. It will still be safe to use. But the battery was so old that the software had to artificially stifle performance to prevent it from shutting down. Instead of turning off the phone and regretting the buyer, I decided to buy a replacement battery and tools from iFixit and replace the battery myself.

It took a little over an hour, but I was able to safely replace the battery, and the iPhone 6 was running fine again. I’m not giving step-by-step instructions here – go to iFixit and grab a kit if you’re after that – but I want to describe my experience, including how easy it was to do, and hopefully Answer: If you also need a new battery, you may have some questions.

Note that any maintenance you take on your devices is entirely at your own risk.

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

The batteries get old over time, and considering that the iPhone 6 was released 6 years ago, it’s no surprise that what I bought didn’t run in prime condition. Once, the phone restarted unexpectedly during use, and it issued a warning that read, Was unable to. Performance management has been applied to help prevent this from happening again. ” Even the phone itself knew it had a battery.

In short, the performance of the phone can be stifled if it can no longer meet the power requirements. There is an option to turn off throttling, but this results in more frequent crashes. No situation is ideal, so changing the battery seemed like a great way to get ahead of me, since it wasn’t my primary phone and I was willing to take risks.

2. How much does a replacement iPhone battery cost?

The problem with my situation in particular was that I bought the phone so low in the first place that spending more money on a battery replacement service negated some of those initial savings. Apple’s official replacement service costs £ 49 ($ 49), more than half the price I paid for the iPhone 6 I bought. Since I was in the middle of the Corona virus lockdown when I tried it, I couldn’t go to the Apple Store to pick it up, and the total cost of sending it by mail was £ 56.44 (approximately $ 75 or AU $ 105).

iFixit, however, sells a DIY replacement pack for £ 35 (including my home mail in Scotland). It costs $ 30 in the US and comes with a shipping cost of $ 37.96. It’s not a big save on Apple’s official alternative, but every little bit helps.

3. What comes in iFixit Battery Fix Kit?

The iFixit Kit comes with a third party replacement battery. no From Apple, since Apple does not sell its parts separately. It also has all the tools needed to unlock the phone and remove the old battery. The only extra thing I needed was a hair dryer to warm up and remove the glue.

4. Does changing the battery void the warranty of your phone?

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

5. Is it safe to replace your iPhone’s battery manually?

It’s not straightforward to answer. iFixit’s guide gives very detailed instructions about the steps involved, but there were some points that made me uneasy. One step involved heating the back of the phone with a hair dryer to loosen the glue while holding the old battery in place.

In particular, he asked her to “warm up a little to touch comfortably”, which I found a bit confusing. Especially since this section also warns that “overheating the iPhone can burn the battery.” But how hot is it? What signs will I see if it gets too hot? I couldn’t find that information, and as I wasn’t sure how close I would get to overheating it.

A short time later, while trying to remove the old battery, I accidentally tore the battery, which looked like a black wrap around the battery. I was pretty sure the battery didn’t puncture itself – no smoke or hiccups – but I would feel much more comfortable if I had “emergency” instructions on what to do if the battery burns out. .

6. Can I replace my iPhone battery myself?

At one point I realized I could, yes, and I’m not usually “useful” in the DIY sense. iFixit’s instructions were easy to follow, and there were only seven internal patches to remove, which were easy to replace.

What bothers me a bit is that iFixit’s instructions end up on its web page at the point where you remove the old battery. In the end, the only instruction was to follow the previous steps in reverse order. Admittedly, this was not particularly difficult to do, but I would appreciate further guidance at that time.

Another problem I ran into was that, while removing the screen, I cracked the screen protector that was in place. I noticed cracks in the hairline and I feared I had damaged the display, but thankfully no damage was done.


With its new battery, this iPhone 6 should run at its best again.

7. Is it possible to replace the iPhone battery?

It really depends on the age and value of your phone. If, like me, you bought a cheap used iPhone and just want to get it back faster, this might be a great way to breathe new life into old tech without spending any money. Done Keep in mind, though, that this won’t be my main phone, nor did I buy it with my own money. The risk was low for me and it wouldn’t be a big deal if I did it wrong and damaged the phone. You will need to consider whether you can really manage without it, and your tolerance for other risks.

If you are using a recent device, such as the iPhone X. ($ 346 on Amazon)For example, I might take it directly to Apple. The savings you make from doing this yourself are not so great as to justify the potential cost of damaging a more expensive phone.
