Well, That Overheated Quickly

[SYMAWD]

My car has MirrorLink (best thing ever), so if I want free nav in my car it's as simple as using Navmii USA which is a free app that uses no data. However, for MirrorLink to work the phone's screen needs to be on, bluetooth needs to be on, GPS needs to be on for Navmii, and 4G needs to be on if I want to do an online destination search. It also needs to be connected to a USB that supplies a small charge (0.5-1A max). That made the phone overheat in about 10 minutes making it stop charging until it cooled back down. Overall I lost 13% in 30 minutes. Holding it up to my A/C vent solved the issue, but getting a vent clip is kind of stupid since the whole point of MirrorLink is that I don't need the phone within sight. I guess I'm just going to have to deal with this?
