As Shreyans said above, it might be a phone issue.

I've been driving a tata since i ever got my first car. A hand-me-down nano from my family. QC issues were a dime a dozen in that one. So the base model was the choice when buying the punch. Aftermarket HU and phone issue aside, i saw QC issues in the paint 5 months after I had bought it. The base stuff works great. But the factory upgrades do have issues. Like the one with the Harrier talked about above. Another friend of mine had issues with stock AA in her new Nexon too.

But yes, I think it's the processor in my phone which is causing my problems.

Experienced the same thing with wired Android auto and a pixel 3a device. It got so hot that the touch capability of the display failed. It’s most likely a phone/device issue.

Have used wired and wireless Apple CarPlay on the same car with no heating on wireless (no charging either). With charging it gets hot but it’s not too bad.

I plug it in the 12v socket and soon it gets so hot that i can literally make an omelette over it.
If i go the wired way, the HU doesn’t put out enough current to charge the phone and it shows 7h+ charging time on 35%. Plus, it doesn’t even charge and rather the battery drains here too. It still gets warm, but not so much. I’ve been using an AC vent mobile holder to keep my phone cool but it means that I have to consistently blast my AC on road trips even when the weather is good outside and it just ruins my mileage. Has anyone experienced the same? And are there any solutions to this issue?

I had the same problem with my Samsung phone and the Altroz OEM system. The mobile service center suggested me to use the original charging cable to charge the phone as well as to connect it with Android auto. Now the phone doesn't heat while charging and also while it's connected to the head unit.

Ok, so I have a S21 Ultra with an Exynos chipset and I havent really experienced any significant heating issues while using AA or even otherwise as such. It is probable that this model may have additional heat dissipation architecture but just saying. However, as a matter of abundant precaution I do sometimes keep the mobile on the co drivers seat and use the ventilation in my Creta in case I am listening to some long "geopolitical" discussion on YT audio. This is more because of the summer heat coming through the windscreen than the phone itself. But yes, the phone discharges faster when using 5G. Therefore the default setting is the power saving mode in my case.

I have noticed that using Android Auto or Apple Carplay (both wireless and wired) does heat up my devices to an extent. Wireless makes the iPhone heat up more though. For reference sake, I'm using a Samsung Galaxy S23 Ultra, Samsung Galaxy Z Fold 3 and an iPhone 14 Pro Max. The car I drive is XUV700.

Since I drive the XUV700, Apple Carplay (AC) disconnects a lot of times, even while driving. So I'm forced to use Android Auto (AA) which is very very stable on the HU. When using AA wireless, I have noticed that the phone tends to heat up but I just turn off location services and that cools down the phone somewhat.

It is a big contributor but if feasible, try to manage the other variables too :

- ambient temperature
- phone in contact with direct sunlight
- whether charging and if yes fast charging which generates more heat than normal charging(<10W)
- wireless charging generates a lot of heat anyway so not recommended in a hot cabin
- phone covers/guards : will reduce heat dissipation

Just be aware of what causes your phone to heat and manage them for your case.
I doubt the HU can do anything more than throttle the charging speed causing further heating but its definitely not the primary cause.

For reference the first and only time I saw the sequence of rapid battery-drain, power-saving, overheat-message and shutdown, was on a Moto X2 running Snapdragon 801, in a Jetta/Octavia can't recall, connected via blue tooth to the ICE(no fancy screens then)
The contributing factors were the slightly hot cabin(even with AC) due to the desert sun shining on the central console where the phone was kept with screen and maps navigation on using 4G.

Even today regardless of the chipset, if you continuously browse/watch for 2 hours even on 4G data, the phones get hot. If you add charging to it they get even hotter and also not recommended for safety. I have experienced this across devices, SoCs and price ranges so we can safely deduce that its the norm and we will have to adjust accordingly.

XUV700's Wireless Android Auto + Samsung S22 (Snapdragon, 5G disabled) + Wireless Charging. This is the way it was supposed to be used, wasn't it? Drop your phone in the tray, battery will top up and no wires to plugin for navigation and music.

In a parallel universe maybe!

This combo is unusable for anything over a few mins, and enough to cause scalding on a short roadtrip. The processor starts throttling performance enough to make it unusable - even AA starts lagging. Battery doesn't charge much either - after 5-10% is added, it throws an overheating error and stops recieving the charge even while on the tray.

The solution I use is either 1) battery saver on, and place it inside the front armrest which has a cooling vent or 2) wired AA with WiFi & BT switched off and slow charge, or 3) No AA - good old Bluetooth music and memory based navigation.

I largely blame the phone though for the poor experience, it has pathetic thermal performance even for calls and basic browsing.

I have experienced the same problem with my Nexon with Oneplus 8T. Hopefully there is a solution to it.

I faced heating issue with phone cover on my Samsung Galaxy A70. Without phone cover heat dissipation is better.

Generally I plug-in the charging cable with AA running and keep the phone away from direct sunlight. Intermittently let the phone connect wirelessly.

As others have suggested, try using different charging cables.

Next time while hunting for new phone, do keep in mind the heating factor. Some phones are built for continuous use like gaming and they should fare better in terms of heating.

Samsung M14 5G paired with an aftermarket android HU. Probably a chinese maxxlink one.


Could a product like this help? I have ordered it. Will test it and update here

I have no experience with HU so cannot comment on it but since its a common factor between the 2 phones apart from Exynos SoC, it is also worth exploring.
I guess easier will be to try another phone unless you have access to another HU.

Keep us posted.

The USB-C splitter got delivered but it was defective. Plus, i read up on tech forums that such splitters can end up damaging headunits as power may be directed from the 12v towards the head unit via usb. So its better to avoid them. I recently drove 300kms to my home so I got to test a setup which involved a magnetic phone holder. Its pretty much the same thing as putting your phone's processor part in front of the AC vent. But I also noticed that if I ran AA wirelessly with wired charging on 12v and completely kept the screen off of my phone, it didn't get hot even with the AC being off.

Attaching picture of the setup below.

I have seen this issue with wireless Apple Car play too in the Sonet with iPhones 7 & 12 Pro. The 7 being the worst amongst the two, possibly due to the age factor.

But yeah, I feel the wireless thingy in general takes a major toll on ya phone and that’s possibly the only con that I see.

The above said phones work much cooler when connected to to my 2015 Creta’s wired Carplay.

P. S.: Both OEM headunits.

It's great that you found a workable solution but I don't see the point of using wireless AA with wired charging. Just plug in the wired way, it won't discharge plus give you a smoother experience.

Also, you can try disabling any unnecessary services running as a background process in your phone.

One possible reason, screen resolution of the vehicle.

If the older car`s screen is smaller and has lower resolution (480P) for example instead of a perhaps 720P of the newer vehicle, your phone may have to work harder. The newer phones that natively support 2K \4K displays may not have problems but the older phones may struggle.

What I remember is that Map My India maps (inbuilt) had better resolution than Android Auto when connected to 2017 Verna for example, perhaps the OEM wanted to limit the resolution for AA based on the processor that it had.

These two are well reported common problems in using "Wireless" Android Auto, i.e. overheating and battery drain. I stopped using wireless Android Auto due to this and now just plug in it. It's not confined to Exynos chipset, for instance I am using the latest Snapdragon 8 Gen 2 for Galaxy 23 series and it does the same.

Regarding the device specific information, I use a Samsung S23 Ultra and this has happened most times when I have used it wirelessly. Battery drain pretty much every time, heating most of the times (btw it also gets warm during regular AA, not just crazy hot like in wireless AA). S23 Ultra has insane battery life of 8-9 hours screen-on-time (SOT), but with wireless Android Auto it literally goes down by 50-60% and gives only around 4 hours SOT. The phone will still last all day due to the excellent battery life, but if it was any other phone it probably won't make it.

There are some obvious benefits of plugging in the phone

1) Stable connections
2) Charges your phone
3) Less heating and strain on battery health

Ancillary benefit

4) You tend to leave the phone alone instead of fiddling with it while driving!

Battery drains on using wired AA. It shows slow charging but in reality, it discharges faster. No charging whatsoever. The usb port for AA doesn't put out as much power.
