How to replace the battery on the iPhone 8 and iPhone 8 Plus

How
do I know if I need a new battery in my phone?

Apple
introduced some incredibly detailed battery info with iOS 12, and it’s the
easiest way to determine if you should be getting a new battery for your iPhone
8 or 8 Plus, or if it’s still fine.
To
find your battery info:

How do I get my
battery replaced at Apple?

You
will want to check out Apple’s iPhone BatteryReplacement page and select the option that will be most convenient
for you. Options include:

Ok, I’ll take it to
Apple. What will that cost?

If
you have AppleCare+ on your
iPhone 8 or 8 Plus, then it should still be under the extended warranty
coverage. Or if you’re still within the year of purchase, you’d still be under
warranty. A battery replacement will cost nothing if that’s the case, so you
should make the most of it and get a fresh new battery when you need it.
Fordevices that are out of warranty and do not have AppleCare+, a battery
replacement is going to cost $49 for the iPhone 8 and 8 Plus.
However,
Apple is providing battery replacements for only $29 for eligible iPhone 6 and
later (including iPhone 8 and 8 Plus) devices. But this is only going on until
Dec. 31, 2018, and prices return to the normal $49 in the new year.

But I am not close
to an Apple Store. Can I do it myself?

Technically,yes, you can choose to go with the DIY route. However, it’s actually a pretty
lengthy process, and you’re going to need a good amount of time and patience to
replace the battery yourself. We don’t really recommend this since it does void
your warranty if you open up your device.
However,
if you insist, then we recommend following iFixIt’s guides for the iPhone 8 battery replacement and iPhone 8 Plusbattery replacement.

What
about a third-party cell phone repair shop?

Thisis where it can get a little tricky. If you go this route, you should
definitely only go to an Apple Certified business. Otherwise, if you get your
battery replaced at a non-certified shop, it will void your warranty since it’s
not Apple Certified.
Of
course, if you’re already out-of-warranty anyway, then it wouldn’t matter too
much.
