Help Does your N1 get hot when running satnav NAVIGATION??

theartfullodger · Jul 17, 2010

I usually use my car's inbuilt SatNav (well, bigger screen, bigger buttons 2 press) but ran good 'ole Google's a couple of times recently... (it does things the car's doesn't... ) and found the beast was hot / very warm afterwards & the battery only @ 70% whilst being used plugged into a car-charger... (Charger otherwise consistently gets her to 100% comfortably).

Is it just me (again) or does she use a lot of electricity ?? I was running with (IIRC) just "Traffic view" as an added layer (I've yet to understand what that gives me in UK & how currant the info is..)

Regards & Thanks in advance...

I was not running anything else

PS It lives in a case, Amzer one, and almost never is hot ...

Before I bought the car dock from Google, when I used the navigation my phone seemed warmer than usual, but not too bad. Once I got the car dock, however, my phone gets really hot ... not just warm, but actually hot. So far this hasn't affected the phone in any way, but I do worry about the battery life as I read that it could shorten battery life if it runs hot frequently. I'm thinking of investing in one of those small automobile fans to protect my phone while it is navigating.

It can get hot while in use, due to the phone's GPS running, the screen being permanently on and the processor churning away plus the bluetooth and 3G running so it's quite taxing on the phone and power source. If your PSU doesn't reliably chuck out 2 amps then the battery will be depleted while doing this as the phone draws nearly 2 amps while running sat nav. If the phone is in the window where the sun can get at it, then it'll get warmed by that too, adding to the heat. If you can, place it so the phone is shielded by a sun visor or something.

I use it regularly in an open-top car with no sun visors at all, and even in the summer it works fine and despite getting hot, it keeps working. Sometimes if it gets too hot it seems the phone stops taking charge (to keep the heat down), if it gets too hot I think it'll shut down to stop damage, that's not happened to me yet.

I normally use my car's GPS, so don't often use my N1 for that. However, the other day I did use it for a couple of hours. I used copilot as my GPS program. I kept the unit down in the interior of the car, so it wasn't exposed to the sun and air flow wasn't blocked. I wasn't using bluetooth or 3g at the time. It did get very hot to the touch. A couple of minutes after I got home and turned the GPS off, I thought to check the battery temperature with System Monitor (obtained thru android market). It read 115

I got it so hot that the screen stopped responding once lol

I just drove to work and had the phone in my pocket connected to BT for phone in car connection, It was in the case and when I got to my destination it was hot and the screen would not work til it cooled down.....

We ran a combo of Google with traffic and copilot down to Devon over a bank holiday. Phone was pretty drained by the time we got there and it was sat on my lap with one of the kids cardies as I couldn't have it on my lap.
Google traffic isn't bad we skirted Bristol on it's traffic advice - for main routes it's usually pretty accurate.

Thanks for that comment. My temperature indicator said 120 and it scared me that it was that high. So, what is considered "excessively" hot by electronics standards?

I probably spoke too soon on that, as I don't really know what's too hot. I do know that on my DirectTV receiver the internal temperature runs around 125-130, and that's with a cooling fan in operation. Perhaps what's more important is the battery and what's too hot for that, and I don't know. Since my DirectTV receiver doesn't have a battery, it could be a completely different story.

Based on the other comments here, it would seem that the N1 does protect itself by shutting down at least part of itself when it gets too hot.

To prevent the phone from gettin too hot, lower the screen brightness. I used to run Navigation w screen at max brightness and N1 got boilin hot. One time when I was done w a trip my phone became unresponsive. I now use the medium brightness setting. The screen is still visible.

The Google car charger is has a higher amperage than the stock wall charger. I suspect they choose this due to the car charger needin power faster due to the energy hog screen. The battery might b able to handle the heat but the touch screen is more erratic than w the wall charger. (When phone battery charge is low n ur using wall charger, the touch screen closest to trackball starts becomin unresponsive or registerin wrong touch). I ordered a Motorola car charger who's specs r more in line w wall charger. I'll b postin details here:

I'm not live in US and I try to using this, but it's not true.

WHAT?

I'm guessing he said that he uses it outside the US and has not had any issues of the N1 getting hot. Though, I could be wrong.

There's no way I would ever let my Nexus One go above 100 degree's F*. Thats just madness to allow your battery to degrade like that :eek:

If it starts getting close to that 100* limit I just hold it in front of the Air Conditioning vent to cool it down. This works REALLY fast. I've had it at 98* and after 4 min it went down to 83* while the GPS was still running.

Interesting: According to the terms-of-sale (I kept a copy..)

If you are a purchaser of the Device in the EU, you are entitled to a two-year warranty for parts, labor, and service.

So... as I sees it if the battery c***ps out after 1 year 11 months good 'ole Google (or probably their agent HTC) must cough up a new one..

Kinda suspect Google would prefer not to meet me in court to discuss the matter & would probably pay..

What, why do I think it is Google not HTC?? Well the contract-4-sale was between me-and-Google.. so in Englerlish(or Scottish) law then they gotta sort it. They can ask me to liaise with HTC over the matter...

Thanks for the tip on air-con vent: mind you that's where my 'phone holder is & when running NAVIGATION it gets real-real hot... (being charged...). Next time I'll try it with the case/bumper off...

Cheers!
