When I found anon eBay for just £ 75 ($ 95, AU $ 1
After an hour of work I changed the battery and the iPhone 6 ran 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 experience, including how easy it was to do, and hopefully answer some of the questions you have if you too needs a new battery.
Note that all maintenance that you do on your own devices is at your own risk.
1. Why do you need to replace an iPhone battery?
Batteries age over time, and since the iPhone 6 was released six years ago, it was no surprise that the one I bought was not in top condition. On one occasion, the phone restarted unexpectedly while in use, and an alert window appeared stating, "This iPhone turned off unexpectedly because the battery was unable to deliver the required peak power. Performance management has been applied to prevent this from happening again. "Even the phone himself knew he had a bum battery.
Basically, the performance of a phone can slow down if it can no longer meet the power requirements. There is the option to disable the restriction, but this will lead to more crashes. Neither situation is ideal, so battery replacement seemed like a smart way to get ahead.
2. How much does a replacement iPhone battery cost?
The problem with my situation, in particular, was that I bought the phone for so little in the first place that spending more money on a battery replacement service canceled out some of those initial savings. Apple's official replacement service costs £ 49 ($ 49), which is more than half the price of my iPhone 6 I bought. In the midst of blocking the coronavirus, it also meant that going to an Apple Store wasn't really an option, and sending it by mail would add up to a total cost of £ 56.44.
However, iFixit sells a do-it-yourself replacement pack for £ 35 (including shipping to my home in Scotland). It costs $ 30 in the US and shipping costs are $ 37.96. It's not a huge savings on Apple's official replacement, but every little bit helps.
3. What is included in the iFixit battery recovery kit?
iFixit Kit comes with a third party replacement battery that is not from Apple since Apple does not sell its parts separately. It also has all the tools necessary to open the phone and remove the old battery. All I needed was a hair dryer to heat up and remove the glue.
4. Does your phone's warranty expire if you replace a battery?
Opening an iPhone will void the warranty, but if your battery is so old that it needs to be replaced, chances are you no longer have the 12 month warranty period.
5. Is it safe to replace your iPhone battery yourself?
This is not so easy to answer. The iFixit guide provides very detailed instructions on the steps, but there were a few points that made me nervous. One step was warming up the back of the phone with a hair dryer to loosen the glue that held the old battery in place.
More specifically, it noted that the heat is "a little too warm to touch comfortably", which I found 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 overheated? I couldn't find this information, and as such, I wasn't sure how close I was to overheating. that battery. I was pretty sure the battery itself had not been punctured – there was no smoke or hiss – but I would have felt much more comfortable if I had 'emergency' instructions on what to do if the battery would ignite.
6. Can I replace the battery of my iPhone myself?
To some extent, yes, and I'm not normally "handy" at DIY. 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 iFixit's instructions on the web page end at the point where you remove the old battery. The only instruction in the claim was to reverse the previous steps. Admittedly, that wasn't particularly difficult to do, but I would have liked more guidance at the time.
One problem I ran into independently of iFixit was that while removing the screen I cracked the screen protector that was in place. I noticed the hairline cracks and was afraid I might have damaged the display myself, but luckily that was unharmed.
7. Is it worth replacing an iPhone battery?
It really depends on the age and value of your phone. If, like me, you've bought a cheap used iPhone and just want to get it back up to speed, it's a great way to breathe new life into old technology without spending a fortune. Keep in mind though that this wouldn't be my main phone nor did I buy it with my own money. For me, the risk was low and if I had done it wrong and ruined the phone it wouldn't have been a big deal. You should consider whether you can really do without it in case the worst happens.
If you use a more recent device, such as an iPhone X ($ 900 at Boost Mobile) I would probably take it directly to Apple, for example. The savings you can achieve by doing it yourself are not so great as to justify the potential cost of damaging a more valuable handset.
