Observe that any upkeep you do by yourself units is finished fully at your personal danger.

1. Why do that you must change 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 working 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 surprising shutdown as a result of the battery was unable to ship the required peak energy. Efficiency administration has been utilized to assist stop this from occurring 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 extra money 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 course of the coronavirus lockdown additionally meant that attending to an Apple retailer is not actually an possibility, and sending it in by means of the mail would deliver the entire value to £56.44.

iFixit, nonetheless, sells a DIY substitute pack for £35 (together with postage to my dwelling in Scotland). It prices $30 within the US and with transport prices that involves $37.96. It is not 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 components individually. It additionally has all of the instruments wanted to open the telephone and take away the previous 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 previous battery out was difficult, and I wasn’t all the time certain I used to be doing it safely.

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

This one is not so simple to reply. iFixit’s information provides 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 previous battery in place. 

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

Shortly after, whereas attempting to pry out the previous battery, I by chance 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 would have felt much more comfy if I had “emergency” directions available about what to do if the battery did ignite. 

6. Can I change my iPhone battery myself?

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

What I discovered a little bit complicated was that iFixit’s directions on its net web page finish on the level the place you take away the previous battery. The one instruction within the conclusion was to observe the earlier steps in reverse order. Admittedly, that wasn’t notably troublesome to do, however I might have appreciated extra steerage at that time. 

One difficulty I bumped into independently from iFixit was that, throughout the elimination of the display screen, I cracked the display screen protector that was in place. I seen the hairline cracks and was apprehensive that I would broken the show itself, however fortunately that was unhurt.

7. Is it value changing an iPhone battery?

It actually will depend on 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 previous tech with out spending a fortune. Keep in mind, although, that this wasn’t going to be my major telephone, nor did I purchase it with my very own cash. For me, the danger was low and had I accomplished it fallacious and ruined the telephone, it would not have been an enormous drawback. 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 Increase Cell), for instance, I would most likely 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 helpful handset.
