TheiPhone X,released in 2017, is differs drastically from all of its predecessors. It was the first iPhone to boast a stunning OLED screen, the first to use Face ID, and the first to ditch the iconic iPhone home button for an updated continuous screen appearance. Despite its veteran status as a five-year-old phone, its modern appearance and high quality have kept it in demand as an original phone, a second-hand buy, a hand-me-down, and a refurbished model.

Like any smartphone, there are always a few issues that crop up over time. We’ve compiled a list of common iPhone X problems and collected a series of fixes to make sure your iPhone X works perfectly.

Problem: Battery is draining too fast

With a five-year-old phone, you can’t expect battery life to be quite what it was. That said, suspiciously fast-draining batteries can indicate a problem, so if you are really struggling with battery life, it’s time to engage a few mitigating actions.

Possible solutions:

Problem: “This accessory is not optimized for this iPhone” error message

This error message may appear when you attach either an old or a new accessory, and typically has specific causes that are not necessarily related to product compatibility.

Problem: Can’t update iOS

iOS 15 is the latest version of the iPhone operating system and every model of the iPhone X is compatible with iOS 15. When something goes wrong with the download, you should be able to fix it.

Problem: Performance slowdowns or stuttering

If you’ve owned the iPhone X since its launch in 2017, chances are you’ve encountered lag and slowdowns in performance over the years. This is to be expected. Users onRedditandApple support forumshave described many instances of both issues.

Problem: Muffled speakers or poor audio quality

The iPhone X’s speakers provide excellent audio quality, but they’re still susceptible to debris and dust.Redditusers have been complaining their iPhone X speakers sound muffled or can only be heard when switched to landscape mode. Before you do anything, make sure your iPhone is not set to silent mode, and that you have turned up the volume (seriously).

Problem: Dropped calls

This is an issue that has a lot of potential causes, including your network and location. Nevertheless, there are some things you’re able to try to reduce or eradicate dropped calls.

Problem: Won’t charge, charging slowly, or wireless charging not working

Some users have experienced problems with iPhone X charging.Threadsat theApplesupportforumdescribe the iPhone X refusing to charge at all, slow charging, or wireless charging not working properly.

Problem: GPS not working properly

There are multiplethreadsat theApplesupportforumsabout GPS struggling to get an accurate fix, drifting around, or just not working.

Problem: Touchscreen not responding or ghost touches

A few iPhone X owners suffered from a touchscreen glitch that results in the screen reacting without being touched and sometimes in the screen not responding to touch properly. There are severalthreadsat theApplesupport forumabout these issues, andApple has acknowledgedthat some iPhone X displays “may experience touch issues due to a component that might fail on the display module.” While there are no longer free repairs on such an old phone, there are still ways to rectify the problem.

Problem: Face ID not working properly

People have quickly gotten used to unlocking their iPhones with their faces, but it seems that Face ID does not perform perfectly for everyone. Face ID fails most often after a software update.

Problem: Screen freezing

We’ve seen a few reports at theAppleforumsand theMacRumors forumabout the iPhone X screen refusing to turn back on, refusing to turn off, or freezing up intermittently.

Problem: Screen burn-in

Shortly after the release of the iPhone X, Apple put out astatementabout the OLED display used in the phone. The company noted that over time, “image persistence” or “burn-in” could appear. Burn-in occurs when a static image is left on the screen for a long time and gets burned into the display permanently. For example, if you leave your iPhone X screen on for quite a while sitting on the home screen, the icon of an app may get burned into the screen, so that you can see its faint outline when watching a video. OLED screens areoften proneto the problem, but it’s not likely to affect most people.

Problem: Not working in cold temperatures

Several users onReddithave reported that the iPhone X stops working when they are out in cold temperatures. The problem typically only lasts a few seconds, though some have experienced a longer freeze-up. Some common-sense procedures can help.

Problem: Green line appearing on screen

According to an Apple Insiderreport, a handful of iPhone X users see a continuous vertical green line on one side of the screen — also referred to as the green line of death. The line doesn’t appear immediately after turning the phone on, but after being used for some time. Samsung, the iPhone X display manufacturer, had a similar problem with the Samsung Galaxy S7. This is a known hardware problem for which users are not at fault and for which there is no software fix. Luckily, it is not a widespread problem.

Problem: Crackling speakers at high volume

Some users have noticed a crackling noise when they use their iPhone X’s speakers at a higher volume. Many of these reports were seen amongApple forums,Reddit, and in theMacRumors forum. This problem is not widespread.
