As a long-time iPhone user, it’s only a matter of time before my once-shiny-new iPhone feels like a useless puck that needs to be plugged into a wall or a 24/7/365 wireless charger. With my iPhone 14 Pro, it took about three years.

I got my 14 Pro in January 2023, and I was very happy. It was quick and zippy, and felt like it could last for days. After a few years of consistent use, my phone never held a charge for more than a few hours, and I noticed a noticeable increase in how quickly my battery drained once it got past 60%.

My once zippy smartphone now needed a bunch of batteries wherever I went, and it was getting complicated. But it wasn’t until I wrote an iPhone battery tips article that I realized how bad my battery really was.

Apple’s battery health analyzer showed that my battery was only charging about 72%, meaning I was never getting a full charge or maximum capacity, even if I thought I was. My bad battery made my iPhone feel like a burden, and I was already planning to upgrade to the iPhone 18 series next September, to get a better battery.

It turns out I won’t need to, because I brought my iPhone 14 Pro to the doctor, and Apple refurbished it.

Diagnosis

Your iPhone battery will literally tell you it is cooked. Navigate to Settings > Battery > Battery Health & Charging to check your battery health and see Apple’s recommendations. In my case, this is what my screen looked like when I checked the battery on my iPhone 14 Pro in April 2026.

Apple called and said my battery was seriously damaged and offered steps to schedule a battery replacement. At first, I didn’t listen. After a few weeks, it became clear that this junky battery was no longer working, and it was going to be a PIA on my upcoming September trip to Italy if I didn’t get it fixed.

Since I wasn’t sure about updating my phone next year, I decided to just pay the money and get my battery back to 100%.

When I finally decided to replace my battery in June, I clicked on “Find Your Service Options” and was able to schedule an appointment at my local Apple store within days. Apple also provides an estimate of the cost of your battery replacement, specific to your iPhone model and any service you may have. For my iPhone 14 Pro, the average was $99.

Examination

When I arrived at the Apple store on the day of my appointment, I walked in with a team member, who made me wait a few minutes until they were ready for me. I was then asked to turn off Bluetooth and location services and sign in with my Apple ID. The Apple team ran a few diagnostic tests of their own to confirm that my battery was, in fact, a piece of doo doo (it was) and to check the health of other parts of my phone.

After a few minutes, I was informed that my phone was in good condition (minus the battery) and that they could replace the battery that day. I immediately handed my iPhone over to my local Apple store and spent the next two hours shopping and running errands.

It is very important that, if you choose to replace your battery, you know your Apple ID and password. You will also need to know your iPhone passcode.

The pick-up

Before I left, Apple gave an estimated time to retrieve my phone, and I returned about 15 minutes after that time. My phone was waiting for me, so the whole shift took less than two hours. Of course, this varies by location, time of day, and day of the week, but I was impressed with the efficiency of the entire process.

Also: How to download the iOS 27 developer beta (and which iPhone models support it)

When I downloaded, I was asked to sign in to my iPhone using my Apple ID, showed the health of my new battery, and asked to complete the payment. My iPhone 14 Pro was (on paper) good as new. My battery life has been very good, with a maximum capacity of 100% now showing in my results.

The cost to replace my battery was $99, and after tax, my total was $105.94. I’ve probably spent more money on MagSafe batteries and other charging accessories over the past year trying to deal with a damaged battery than it would have cost me to fix the whole problem.

The result

I was impressed with the entire process, from diagnosing it on my iPhone to the quick installation at the store. I felt like $99 was fair for a battery replacement, especially if I plan to keep my phone even 3-6 months longer. It drops to about $1 a day if I only hold on to my phone in September, when we expect Apple to release new models, and even less if I decide to keep it longer.

It’s really a win-win. Since fixing my battery fixed my biggest problem with my iPhone, and all my other devices are in good working order, I’ll probably stick with my 14 Pro until it needs a battery replacement.

Also: I never use a new iPhone until I change these settings – why is it such a big deal

Sometimes the solution isn’t a new one, but rather a fix that already works, and this affordable fix saved me over $1,000 on a new iPhone. Ever since I fixed my battery, I’ve seen a huge improvement in my phone’s ability to hold a charge and a reduced need to carry a portable power option everywhere I go.

Also, Apple says iOS 27 brings the usual speed and performance improvements to iPhones, and several older models support it, so if you’re toying with upgrading your device, maybe try testing it first. Your iPhone is probably still kicking; it just needs some TLC. There are also ways to do this yourself even less with the likes of iFixit or similar methods, but I was happy to pay a professional to take it off my plate.
