Overheating and not charging

vortexco — Mon, 20 Aug 2012 08:29:51 GMT

Drove to Gatwick from Norfolk on Sunday, and as you may or may not be aware is was a hot day. My car does not AC so it was hot in it.

I was using SAT Nav software on my phone and a genuine Sony car charger and lead.

The charging (spark) icon was showing so i assumed that it was charging.

But within 3 miles of my dest, the phones battery died and the phone shut off.

When i found the location that i was going to i removed the phone from the windscreen (nearly burn't myself on it) and removed the battery to let it cool down.

I left it off for a couple of hours before starting my return journey, and reconnected the charger and by the time i was at Dartford crossing it had recharged fully.

My question is, because i had the phone mounted in the windscreen on such a hot day, the charger plugged in with a sat nav app running which would have kept the screen switched on, using the CPU, would this have overheated the phone and caused it not to charge? Could i have done permenant damage to it? P.S it seems ok now though.

Thank you

Carl

You shouldn't have done that.

The temperature can get up to 50 to 60 degrees Celsius on the windshield under the sun in Summer.

Yes, there is a temperature sensor for the battery, so when it is too hot, it won't charge. The phone's charging circuitry needs to monitor the battery temp so if it rises beyond a given threshold it backs the charging current off until the temperature stablises, ensuring the battery remains within safe limits.
