Hi, few weeks/months, I’ve found my iPhone 3G way too hot while using waze than before. I thought that it was because of the phone itself (old iPhone, battery was bad etc…). However, last weekend I bought new iPhone 4, tried several times the waze (and also other navigation apps) but just waze make my iPhone almost untouchable. Is there anything I can do with that? Does somebody have the same problem?
I got a cradle that attaches to an air vent so the phone is always in the path of cool air.
mmm, sounds interesting, but it’s impossible in my car. The air vent is too far from my phone holder 
But I think it must be the waze problem, because other navigations (or apps) don’t make the iPhone that hot…
This is a side affect of using waze. Other navigation apps don’t use the network as much as waze. Most of them ask for the maps in the area, and that is it, they are cached no other need to use the network. With waze social and traffic data, waze both receives data, and more importantly sends data a lot. This, coupled with the GPS usage, and if you have the phone charging all adds up to a lot of components running and generating heat. I find my gets warm, but not so hot I can’t hold it.
that sounds logical. But I would swear that it wasn’t that way in previous version…
Thanks for explanation 
Well unless you live in Australia, it’s just now gotten to summer. 
I used nokia and now using samsung galaxy. Both of them have the same problem, warm but not hot.
Also it drains the battery really fast. Waze should improve it :oops:
I’m sorry… but how is waze suppose to fix a hardware issue?
The reasons for using this software over other navigation software… traffic, reports, social messages, require waze to communicate with a central server often. Then the GPS is needed. Both of these use power and will heat most devices with continual use.
I think the suggestion was that a relatively recent code change in Waze has caused additional processing/antenna usage activity and a subsequent increase in unit temperature is the result.
Exactly. I’m almost sure it’s problem of the last version. I’m using waze for more than a year and it warm the iPhone that much just in last few weeks (maybe months). They must have changed something, that make it that warm…
Version 3.2, problem still there, iPhone 4s gets quite warm, hot almost, back panel and metal rim on the sides.
It’s an iPhone issue, not Waze. Waze just uses the hardware that’s available.
Not so fast… I’ve got a SE Xperia Neo w/Android, and it too is building up to be much hotter than just a little while back. My first thought was that it’s because the screen is on all the time, but it wasn’t as hot when I started using Waze.
The device can get rather hot. The more functions that you are using, the warmer it gets.
- Screen
- GPS
- Cellular Modem
- Bluetooth
- Charging device
I notice that it’s worse when using Waze and charging from a low battery state. I have a dash mount and aim one of my AC vents directly towards my phone to help keep it cool. I have never had a case where my iPhone 4 has shut down due to excessive heat. The iPhone has a built in sensor that will power off your iPhone, due to heat, before damage occurs. So your device feeling hot is not necessarily causing any problems.
My advice, just don’t use waze while running Pandora on a charging battery in a car with black seats that you just turned off so you could fill the tank under the blazing sun of an early June heatwave. That’s how I learned about the overheat shutdown mechanism…
Now that summer is here, I’m getting a lot of ‘Temperature’ shutdowns. Just have to hold it in front of the A/C vent for a minute. Not much you can do besides turn on the defrost and send some cool air up there.
Get a vent mount. Their not as convenient as window or dash mounts, mine I have to move into position after I shift the vehicle into drive. But it stays nice and cool in front of the vent, no overheating.
You are right about this being fairly recent. I used to use Waze quite a while back, and I never had this problem. In the past few weeks my phone gets REALLY hot when I keep Waze running while charging, and I’ve gotten the overheating shut down message a few times.
I really love the concept and execution of Waze, but sadly, I think it’s just not practical. I don’t want to risk damaging my $600 phone for a GPS app, even if it is better than most. The other issue is that it seems to be sending so much unnecessary data constantly, and with more and more data caps, it’s just not worth it anymore.
I guess I’ll be switching to something that doesn’t feel the need to take over my entire phone.
I have always noticed the very high temperature from using Waze in the car, but I have not seen any additional increase since this last update on my side.
Yes this application is using every possible element of power and if you are also charging it at the same time there is a very large energy transfer which is converting to heat. Like gettingthere, I decided to use a vent mount in my car from Proclips and it works very well and helps keep it cool.
I find Waze so useful that I would even dedicate my iPhone to be my GPS in the car.
If using the hardware that apple designs and allowed to be used simultaneously could damage the device, that’s an Apple design problem not Waze. You can do the same with multiple apps simultaneously and you get the same effect. Just because Waze takes advantage of the subsystems available doesn’t mean it’s the fault of Waze it gets too hot. That makes no sense.

If it looks strange, or I used bad grammar or misspelled anything, it’s my phone’s fault.
