The iPhone 11 is joining the ranks of older phones, now two generations behind the current iPhone 13. Nonetheless, the iPhone 11 is and will remain a terrific, modern smartphone with plenty of life for years to come. That’s why owners of Apple’s 2019 iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max are committed to solving any lingering problems related to their phone.

Fortunately, the initial functional problems with iPhone 11 were common to most other Apple smartphones that year: They were linked mostly to Apple’s problematic iOS 13. With the much smoother release of iOS 14 and similar ease of use with the current iOS 15, many of the pressing issues faded away for most owners. Some lingering problems may persist, and here is what you can do about them.

If you’re having problems with the iPhone 11’s Face ID unlock feature, here’s what to do.

Make sure your iPhone 11 is running the latest version of iOS 14 or iOS 15. That should quickly clear everything up. If it does not, then do the following.

Tap Settings > Face ID & Passcode. Then, make sure that Face ID is set up on your phone and that all of the features you’re trying to use Face ID with are enabled. If you’re having issues using your face to unlock your phone, make sure you’re looking directly at the screen and that the room is light enough so that the camera can detect your face. Try bringing the iPhone 11 closer to your face or position it more at face level. Make sure there’s no dirt, dust, or debris blocking the iPhone’s TrueDepth camera.

If you often change your appearance, consider adding an alternate appearance to Face ID. Go to Settings > Face ID & Passcode >Set Up an Alternate Appearance.

If service is spotty or you’re repeatedly unable to connect to your network, here’s how to handle it.

The first thing to do is restart your phone and turn on Airplane Mode on for 30 seconds before turning it off. If that doesn’t solve the problem, check your service provider for outages at Down Detector or look for reports on local social media.

In iOS 15, you can toggle Cellular Data and/or LTE off and on.

You can also toggle Cellular Data off and on. Go to Settings > Cellular > Cellular Data. Toggle it off and then back on.

If you are having problems connecting to Wi-Fi, or your connection repeatedly drops or is slow, there are a few things you can do before you lay hands on your phone.

First, make sure your Wi-Fi is working correctly or reset your router to make sure. If you’re connected to your network, unplug the router for a minute, plug it back in, and reconnect. If your home Wi-Fi is OK, then pick up your phone and make sure you have your Wi-Fi password on hand before you get started.

Go to Settings > Wi-Fi. Tap the info circle. Tap Forget This Network and try to reconnect. You’ll need to re-input your password.

Or try resetting your network via Settings > General > Transfer or Reset iPhone > Reset Network Settings.

Issues with dysfunctional wireless charging are fairly widespread. Some customers with Qi wireless chargers report that after they place certain iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max models on the charger, the iPhone may recognize it as a charger, but will not actually charge, and may even become hot to the touch.

If this is still an issue, you can continue to charge your phone with a wired connection. Make sure to update your iPhone’s OS with the stable iOS 15. Mechanical maneuvers include a power-off reset/restart, which did solve the issue for some people.

If you use a case that stores credit cards or security passes, remove them before charging your phone or just remove the case altogether before charging.

Activation issues are common when you try to get a new phone up and running for the first time, regardless of the model, and the iPhone 11 is no different.

If you’re having problems activating the iPhone 11, first make sure that all systems are up and running by checking Apple's System Status page . If something is not toggled green, wait until all systems are running and try again. If it’s green and still not operative, make sure your phone has a SIM card inserted. If you can switch the SIM card from your old phone into your new one, try that first. If you get a No SIM or Invalid SIM error message, Apple suggests the following steps.

If you experience problems with any aspect of audio function, there are various remedies you can try.

A common complaint with various iPhone 11 units is that they get uncomfortably hot, especially while using resource-heavy features like GPS. This has owners concerned about the long-term effect on battery life.

If you’re still experiencing this issue, contact Apple Support for assistance.

Some iPhone 11 owners noted problems in iOS 13 with connecting peripherals via Bluetooth. Those issues include anything from trouble pairing their phone to the car to maintaining a connection after the device has finally paired, to repeated connection and disconnection.

Before testing any of these suggestions, ensure that your iOS has been updated to the latest version available, such as iOS 15.

You can also forget and then reconnect the problematic Bluetooth device.

If you still can’t connect, try resetting your phone’s network settings.

iPhone 11 models have experienced a variety of battery problems over time. The iPhone 11 Pro Max, for example, has been associated with premature battery wear. In 2021, a bug affecting only iPhone 11 models also led to inaccurate battery reports on iOS and related problems.

Always go to Settings > Battery > Battery Health if you fear a battery issue. Here you can check out the current condition of your battery and see if there are any obvious issues. If you are experiencing significant battery loss, it’s a good idea to take/send your iPhone in for professional repair or replacement.

Fixes in iOS should also alleviate the problem. Ideally, you should upgrade to iOS 15. With iOS 14.5, a fix enabled the iOS to recalibrate the battery reporting function via the Battery Health section. It takes time, as the function needs a few weeks to properly measure and recalibrate the battery. If the recalibration finds the battery to be damaged, it will walk you through the steps for a full replacement.

The iPhone 11 can have up to 256GB of storage, but if you save a lot of files and apps to your phone then even this can become limiting. Fortunately, there are built-in ways to deal with low storage space.

In iOS 15, go to Settings > App Store > Offload Unused Apps to get rid of apps that have been inactive for a while, but keep their documents and data. Then, review each app to spot the ones taking up the most space. If you find an egregious offender, select it and view the options for clearing space. For the Music app, for example, you can choose to auto-delete any songs you previously downloaded for offline listening.
