However I used to be much less happy after I came upon the battery had aged to the purpose the place the software program throttled its efficiency. However as a substitute of removing the telephone and getting purchaser’s regret, I made a decision to purchase a substitute battery and instruments from iFixit to have a go at changing the battery myself.

After an hour of labor, I swapped out the battery and the iPhone 6 was operating completely once more. I am not giving step-by-step directions right here — head to iFixit and seize a package if that is what you are after — however I do need to give my experiences, together with how straightforward it was to do, and hopefully reply a few of the questions you might have in case you additionally want a brand new battery.

Word that any upkeep you do by yourself units is completed fully at your individual danger.

1. Why do you’ll want to exchange an iPhone battery?

Batteries age over time, and contemplating that the iPhone 6 was launched six years in the past, it was no shock that the one I purchased wasn’t operating in prime situation. One time, the telephone unexpectedly restarted whereas in use, and it flashed a warning dialogue that learn, “This iPhone has skilled an sudden shutdown as a result of the battery was unable to ship the mandatory peak energy. Efficiency administration has been utilized to assist forestall this from taking place once more.” Even the telephone itself knew it had a bum battery.

2. How a lot does a substitute iPhone battery value?

The issue with my scenario particularly was that I purchased the telephone for thus little within the first place that spending more cash on a battery substitute service negated a few of these preliminary financial savings. Apple’s official substitute service prices £49 ($49), which is greater than half the worth of my iPhone 6 I purchased. Being in the midst of the coronavirus lockdown additionally meant that attending to an Apple retailer is not actually an choice, and sending it in by means of the mail would convey the full value to £56.44.

iFixit, nevertheless, sells a DIY substitute pack for £35 (together with postage to my residence in Scotland). It prices $30 within the US and with transport prices that involves $37.96. It isn’t an enormous saving over Apple’s official substitute, however each little bit helps. 

3. What comes within the iFixit battery repair package?

iFixit’s package comes with a third-party substitute battery that’s not from Apple, since Apple doesn’t promote its elements individually. It additionally has all of the instruments wanted to open the telephone and take away the outdated battery. The one extra factor I wanted was a hairdryer to warmth up and take away the glue.

4. Does changing a battery void your telephone guarantee? 

Opening up an iPhone will void the guarantee, but when your battery is aged to the purpose that it wants changing, odds are you are already out of the 12-month guarantee interval. 


Prying the outdated battery out was difficult, and I wasn’t at all times certain I used to be doing it safely.

5. Is it protected to exchange your iPhone battery your self? 

This one is not so easy to reply. iFixit’s information offers very detailed directions on the steps concerned, however there have been a few factors that made me nervous. One step concerned heating up the again of the telephone with a hair dryer with the intention to loosen the glue holding the outdated battery in place. 

Particularly, it famous that the warmth be “barely too heat to the touch comfortably,” which I discovered somewhat obscure. Particularly since that part additionally warned that “overheating the iPhone might ignite the battery.” However how scorching is simply too scorching? What indicators would I see if it is overheating? I couldn’t discover this data, and as such wasn’t too certain how near overheating I could have been.

Shortly after, whereas making an attempt to pry out the outdated battery, I by accident ripped into what regarded just like the black wrapping round that battery. I used to be fairly certain that the battery itself wasn’t punctured — there was no smoke or hissing — however I might have felt much more snug if I had “emergency” directions readily available about what to do if the battery did ignite. 

6. Can I exchange my iPhone battery myself?

Up to some extent, sure, and I am not usually “helpful” in a DIY sense. iFixit’s directions have been straightforward to comply with, and there have been solely seven inside screws to take away, which have been straightforward to exchange.

What I discovered somewhat complicated was that iFixit’s directions on its net web page finish on the level the place you take away the outdated battery. The one instruction within the conclusion was to comply with the earlier steps in reverse order. Admittedly, that wasn’t significantly tough to do, however I’d have appreciated extra steerage at that time. 

One challenge I bumped into independently from iFixit was that, in the course of the elimination of the display screen, I cracked the display screen protector that was in place. I observed the hairline cracks and was anxious that I might broken the show itself, however fortunately that was unhurt.

7. Is it value changing an iPhone battery?

It actually is determined by the age and worth of your telephone. If, like me, you purchased an affordable used iPhone and simply need to get it again in control, then it is a good way to breathe new life into outdated tech with out spending a fortune. Keep in mind, although, that this wasn’t going to be my foremost telephone, nor did I purchase it with my very own cash. For me, the chance was low and had I finished it incorrect and ruined the telephone, it would not have been a giant downside. You may want to contemplate whether or not you actually can handle with out it, simply in case the worst occurs.

In case you’re utilizing a more moderen gadget, like an iPhone X ($900 at Enhance Cell), for instance, I might in all probability simply take it on to Apple. The financial savings you may get from doing it your self aren’t so nice as to justify the potential value of damaging a extra invaluable handset.
