Some people might not realize it, but Android Auto is actually just an Android app being cast to your vehicle's infotainment screen, whether you're using a wired or wireless connection.
On the wireless side, potential lag issues are difficult to diagnose due to the several variables at play. For example, it could be something as simple as your Bluetooth and Wi-Fi connections being interfered with by a component in your vehicle. I've only used wireless Android Auto a few times, and in my experience, it always suffers from a bit of lag, especially if you're using a third-party wireless dongle — there's just no way around it.
On the other hand, if you're using a wired Android Auto connection and experiencing lag, it's a bit easier to figure out what might be causing the issue. In my particular case, it came down to the cable I was using.
A straightforward solution many people overlook is to make sure Android Auto is up to date. To do this, navigate to the Google Play Store > tap your Profile Icon > Manage Apps & Devices > Updates Available > Android Auto > Update.
Some of the Android Auto lag fixes below can also help with wireless Android Auto, including making sure you aren't running too many apps at once to free up RAM. However, the majority of these solutions focus on improving the responsiveness of wired Android Auto.
Not every USB-C or USB-A cable is built the same
That low-end USB cable you bought at a gas station could be the culprit
In many cases (including mine) Android Auto lag is caused by that cheap, low-end USB cable you're using to connect your Android phone to your vehicle. It might be the cable that came with your phone, or maybe your more expensive cord suddenly stopped working, and you grabbed something quick from the gas station or a dollar store. Either way, it's important to remember that not all USB cables are the same, and that in most cases, the more expensive options are vastly superior.
Android Auto works by generating a continuous video stream while running resource-intensive applications like graphically heavy map apps and music players, while consistently displaying your GPS location. All of this means that a lot of data is being transferred through your USB cable to your car's infotainment screen. With that in mind, a USB 2.0 cable — whether it's USB-A or USB-C — probably won't always get the job done, since it tops out at 480Mbps. Older USB 2.0 cables often have other issues, too, like poor shielding and unreliable power delivery, which can contribute to Android Auto lag and disconnections. A lot of people might not be aware, but the cables that come in the box with most phones only support USB 2.0, including Google's Pixel line and even Apple's iPhone (I used an official Apple USB-C cable with Android Auto for years before realizing this).
Vehicles are also full of potential sources of interference, including the engine, ignition system, and other electrical components, making a properly shielded USB cable integral to a responsive Android Auto experience. This is why I always suggest using a high-quality, shielded USB 3.1 cable that supports 10Gbps to ensure smooth data transfer, which in turn helps make Android Auto more reliable and responsive, even if it's overkill. Lastly, if you're using a USB-A-to-USB-C dongle like I am, make sure it supports at least USB 3.1 passthrough speeds and isn't the bottleneck in your Android Auto connection setup.
Since I don't have a USB 3.1 cable readily available, I've been using an extra Thunderbolt 5 cable with Android Auto that I had left over from a recent project (it supports up to 80Gbps), along with a USB-A-to-C adapter that features 10Gbps data passthrough. This is undeniably more data transfer speed than you need for Android Auto, but it's a high-quality, shielded cord and the fastest and most protected option I have available right now.
It's also worth checking if your car's USB port even supports USB 3.X, because if it doesn't, you won't get the benefit of using a faster cable. However, if that faster, higher-quality cable is shielded, it still might end up being more reliable.

Android Auto's Developer Mode opens up useful options like Default USB Configuration, higher resolutions, and more.
Make sure your Android device is up to date
Give your cache a clear, too
Along with updating Android Auto, make sure your Android device is running the latest version of the operating system and has the latest security patches installed. Google frequently releases stability fixes, especially with its notable monthly Android feature drops, and you want to make sure you have them running on your device.
On top of that, clearing your phone's Android Auto app and Google Play Services cache is always a good idea if you're experiencing lag, since it gives both utilities a clean start. To do this on my Pixel 10 Pro, I navigate to Settings > Apps > Android Auto > Clear Cache. You can also force-stop Android Auto to resolve any potential issues. To clear Google Play Services' cache, head to Settings > Apps > Google Play Services > Clear Cache. Additionally, I always restart my phone after doing this, just for good measure — the classic "have you turned it off and on again" solution is still a solid go-to option here.
Close any apps you don't need open
Make sure battery-saver mode isn't accidentally turned on
If your phone is feeling laggy, you can't expect Android Auto to run smoothly since it's powered directly by your devicet. In many cases, when I find Android Auto isn't as responsive as I'd like, it's because I have several games and other resource-intensive apps running in the background on my phone. I just needed to free up enough of my phone's RAM for Android Auto to run smoothly, especially when I'm running Waze, Spotify, PocketCasts, ChargePoint, and more through Google's infotainment system.
Additionally, if your Android device lags when connected to your vehicle, make sure Battery Saver Mode is turned off. Android power management restricts background activity to extend your battery life. It may suspend services it decides are nonessential, but you need to keep them running in the background for Android Auto to run smoothly. On my Android phones, you can make sure this feature is off by navigating to Settings > Battery > and turning off Battery Saver Mode. It's worth noting that Android phone makers have different names for this feature. For example, with Google's Pixel devices, it's called Battery Saver, while Samsung calls it Power Saving Mode.
