Apple CarPlay and Android Auto Make Your Phone Hot. Here’s How to Keep It Cool

Android Auto and CarPlay have transformed the way people drive. Rather than putting up with whatever infotainment systems car manufacturers have put together, we’re now able to interact with our phones from our car dashboards—with our contacts, our music, our podcasts, and our mapping apps all available. And the list of supported vehicles just keeps growing.

Android Auto 和 CarPlay 彻底改变了人们的驾驶方式。我们不必再忍受汽车制造商预装的那些车载信息娱乐系统，而是可以直接通过汽车仪表盘与手机进行交互，使用我们的联系人、音乐、播客和地图应用程序。而且，支持这些功能的车型名单还在不断增加。

Both the Google and Apple solutions for this are really simple to use too. Most of the time they’ll connect up automatically once you’ve done the initial setup. What you might not realize, though, are the demands that Android Auto and CarPlay put on your phone. Your handset is essentially doing all the regular phone stuff and then powering a large tablet-like display at the same time. That typically includes constantly updating a map in real time.

谷歌和苹果提供的这些解决方案使用起来也非常简单。大多数情况下，一旦完成初始设置，它们就会自动连接。然而，你可能没有意识到 Android Auto 和 CarPlay 对手机提出的要求。你的手机实际上是在处理所有常规任务的同时，还要驱动一个类似平板电脑的大型显示屏。这通常包括实时更新地图。

With that in mind, your Android phone or iPhone can quickly start to lose battery life and heat up when it’s connected to your vehicle, which you’ve perhaps already noticed. To keep your handset cool and your battery in good shape, here’s what you need to do.

考虑到这一点，当你的安卓手机或 iPhone 连接到汽车时，电池电量可能会迅速下降并开始发热，这一点你可能已经注意到了。为了保持手机凉爽并维持电池的良好状态，你需要采取以下措施。

Go Wired if You Can (but Watch the Charging)

如果可以，请使用有线连接（但要注意充电问题）

Wireless Android Auto and CarPlay are convenient, just like wireless charging is convenient, but it puts more stress on your phone. If you’ve got the option of a wired connection, that’s preferable—but that introduces a new potential heat problem, which is that your phone will always be charging up.

无线 Android Auto 和 CarPlay 很方便，就像无线充电一样，但它会给手机带来更大的压力。如果你有有线连接的选项，那是更好的选择——但这会带来一个新的潜在发热问题，即你的手机会一直处于充电状态。

To counter that, you can set charge limits (Battery and charging from Android Settings, Battery > Charging from iOS Settings), or simply make sure your phone is kept in a cool, dark spot of the car.

为了解决这个问题，你可以设置充电限制（在安卓设置中找到“电池和充电”，在 iOS 设置中找到“电池 > 充电”），或者简单地确保手机存放在车内阴凉、避光的地方。

Think About Where Your Phone Is Placed

考虑手机的放置位置

As mentioned above, where your phone is in the car makes a real difference to how hot it’s going to be. If you have your phone’s interface up on your car dashboard, then you don’t necessarily need to have it fixed to the dashboard, too, possibly under direct sunlight. The glove compartment will do just fine.

如上所述，手机在车内的位置对它的发热程度有很大影响。如果你的手机界面已经显示在汽车仪表盘上，那么你就不一定非要把它固定在仪表盘上，以免它暴露在阳光直射下。放在手套箱里就完全没问题。

If you have a mount for your phone, think about attaching it in front of one of your car’s air vents. Blasts of air conditioned air will significantly reduce how hot your handset gets, working like a DIY cooling system.

如果你有手机支架，可以考虑把它安装在汽车空调出风口前面。吹出的冷气会显著降低手机的温度，就像一个自制的冷却系统。

Limit the Work Your Phone Has to Do

限制手机的工作负载

If your phone is hooked up to Android Auto or CarPlay, then it’s probably got some work to do—whether it’s getting you to a destination or streaming music. However, you can still reduce heat by keeping phone tasks down to a minimum. If your calls and (voice-activated) messages can wait, leave them until the end of the journey.

如果你的手机连接了 Android Auto 或 CarPlay，它可能正在处理一些任务——无论是导航到目的地还是播放音乐。不过，你仍然可以通过尽量减少手机任务来降低发热。如果你的通话和（语音激活的）消息可以稍后再处理，那就等到旅程结束再说。

We mentioned offline syncing above, but it doesn’t have to go along with airplane mode. If you sync your tunes, podcasts, and maps to your phone ahead of time, your handset has less work to do while you’re driving since it doesn’t need to pull data from the cloud while also constantly searching for a wireless signal as you travel. Less stress on the modem means less heat overall.

我们上面提到了离线同步，但这并不一定要配合飞行模式使用。如果你提前将音乐、播客和地图同步到手机上，手机在驾驶过程中的工作量就会减少，因为它不需要在从云端获取数据的同时，还要在旅途中不断搜索无线信号。调制解调器的压力越小，整体发热就越少。
