[Q] HTC Desire S radio

---

HI guys

I get my desire S before week ago but I think I have problem in radio as when I leave my phone in stand by for 6 hours it loss 50% from charging with radio switch-on and if I switch-off the radio it loss 2% from charging so I think there is some problem in the Radio pls can anyone help me
really I am so confused with this problem

The only thing that I can think of would be if you were in an area where there is weak 3g signal and the phone if constantly getting on and then Falling off the 3g network.

There are a couple of other threads in this forum all about excessive battery drain, one about excessive drain with screen off, although not specifically about radio, so possibly post this into one of them.

I just use the 2G network
I ask if I update the radio may be the problem will solved ? and how can do that ?
pls to advise me

To upgrade the radio currently with S-ON you can find the HTC/official ROM with the latest revision radio. This would be a little trial and error, install it with the goldcard method and see if it helps. Another idea, if you are just using 2g, have you set the mobile network to GSM only instead of GSM/WCDMA? It may be worth a shot.

Even on 2G only, I think the drain can be severe in an area with very poor signal, because the phone uses much more energy than normal trying to contact a mast.

If you look at Settings > About phone > Battery > Battery use, you would normally expect the display to be the greatest drain on the battery; but in an area with very bad (almost non-existent) signal, you might expect to see Cell standby at over 50%.

In the building where I work, almost no radio signal gets through, so most of us here find our phones reporting "Emergency calls only" and prompting to choose a network.

But even there, I'm only losing about 25% in six hours. The phone gets quite warm though: about 38 degrees C - in airplane mode, it's down to 33 degrees.

I've stopped most things from syncing too much though. Do you perhaps have some apps synchronizing very often (and which therefore do very little when the radio is off) ?

your phone is way too warm unless the room temp is close to that as well.

I already switch-off all synchronizing and did factory reset and try to put on GSM only but the problem didn't solve yet
I thing may be the radio version not compatible with my network or something like this so I ask if can find another version of radio or make upgrade with my phone in S-ON

Hi guys

The problem had been solved as when I replaced the SIM the problem disappeared so I think the problem was in my SIM
thanks for every one who support and help me
I want to say that this phone is great and one of batter HTC phone that released so I hope for more support from XDA

My Desire S only allows GSM/WCDMA or WCDMA..

I would love to go GSM only because my damn house is bewteen 2 3g towers
