N80 Battery hots - Poss cause - Now rectified for ...

Question

In a not so long ago previous post to this forum i wrote that my new N80 battery/phone got hot all of a sudden.
It happened approx five times over several days.
Ive since found the reason why and would like to share, due to some trial and error testing.
Im currently on H3g 3UK network.
The only time the battery starts/ed to get hot is when there is no signal, as when it had got hot, it was when i was visiting friends, who live in villages, so the signal was/is not the same as being in a town.
Now here is the good bit.
After testing, when there is no signal, ie 3g signal or even normal signal, the the phone would have continued to
look for a signal until it had found a signal, it would have logged onto the GSM band and used O2 to make a call.
What is happening now i that when it cant find a signal, the battery starts to get hot. my old phone the nokia 6680 would have found a signal on the GSM band, ie it would have used O2 to make a call.
The N80 does not now / will not even log onto the O2 network if there is not a 3 or 3-3g signal.
Hence why the battery gets hot.
A friend of mine has the nokia 8800 newish silver phone, and used to use his 3 network sim in that phone. However it was using th O2 GSM band, and 3 uk the network sent him a text saying in these words - do not continue to use your sim while out of 3g coverage, see terms and conditions of your pay as you go service etc etc.
He said to me it was because the 8800 type phone was not a 3g handset, so it was obviously costing 3uk network money or their agreement was only to allow O2 to be used in emergencys when there was no 3g signal for 3 customers.
My friend and myself have used his samsung 3g phone to do network searches with a 3 sim in, and it will log onto O2 to make calls. We also used his nokia 8800, and he has also now got a N80 phone contract on Vodaphone, and his network settings are differently laid out, compared to my 3UK network N80 phone.
So this is the reason for the battery on my N80 getting hot. It hasnt done it recently, as ive not been out of town area.
And i can usually get 2 to 3days worth of battery usage from the phone if i dont make many calls, otherwise 36 ish hours is the norm for my phone. My old n6680 was a 2 day battery also, while using it most times for calls.
Hope this is of help to people on 3uk network. As far as im aware, the other networks have a better 3g signal, so most people wont get the problem i got.Message Edited by steve_n80_uk on 27-Jul-2006

nokia phones have always been real slow when you use an external memory. in the user guide for the N91 it mentions you should only use the phone memory for this.
personally, as memory cards are so unreliable, i would stick with using the phone memory. you are probably not going to run out of space any time soon
