I have a lot of signal drops on GSM/EDGE and also 3G/HDSPA? The signal is full but if the phone is is stand by the signal drops and I loose calls. Does anyone have this problem?
Also I noticed when the phone switches from 3G to GSM/EDGE first I have a no signal perioad (couple of seconds).
Could this also be a Service Provider Problem

Hello everyone!
I received my Vibrant from the US a week ago and noticed that when 3G is on, the reception is 1/2 bars at most. While it's connected, the device gets hot in the top part and the battery drains like a F1 racing car.
I though I could see how good is the signal and it's about (-90) - (-100) dbm.
I never had reception issues with my previous phone that is 3 years old (HTC Touch Cruise) whose reception is quite good. My company's antenna is about 1 Km far and it's emitting 3G in the WCDMA 2100 MHz band.
Could any setting improve the reception to avoid heating and battery consumption?
Thanks a lot!!
You may want to try to set it to 2G only if you want a good battery life.

Maybe somebody knows an application that switches from 3G to 2G when the reception is not good. It might be very handy.
Also, I wanted to know what levels are acceptable in dbm for a 3G connection that doesn't drain the battery like crazy.
Thanks for your reply!
Hey guys,
I was wondering if any has the same issue as me. My battery gets really hot when using 3G, H+, H (Whatsoever they want to call this 4G), but when I do the exactly same tasks and same things on WIFi, the temperature drops considerable, it even does not get warm at all. H+ signal displaying is of 4 bars, so it is not a problem of lacking signal strength.
If someone can help me I would really appreciate it.
Mobile data (3g) uses more power because the signal needs to travel way farther. More power = more heat, especially when you're constantly transmitting like a long download or something.

Yes, I know there is more enegery consumption while using 3G, but this happens also when i do not transfer any kind of data.

Why is it that when I'm on wifi, my battery last longer vs while I'm on 3G?

Wifi uses less power, it's a different frequency, as you're much closer to the wifi device than you would be the 3G cell mast.
plus, 3G need to find signal, when you in a place where 3G signal is weak, it will drain more battery
Use it when you need it...
After serval Test while I was in school and at home I found out:
Edge with Datasync on is the worst! Battery drains in 4 to 5h
Hspda/Hsupa with a good connection is way better. Batterylife 7h
If you just turn if off it saves a lot of energy! Up to 36h
So what I am doing now: I turn the Mobile Network off when I see that little E in the top right corner because the connection is so slow anyway..
Specs of my Phone:
HTC Desire HD with RCMix3D KINGDOM v1.1
1370mAh Battery
For actual data transfer, it depends on how often and how much is being sent.
3G transfers faster, so if you're just going after 1 thing, it can be less draining than 2G, assuming full signal strength on both, because it's in use for less time.
Yes radio and signal strength affect the battery. Some radios work better than others in certain areas thus giving a better signal. If you are right next to a tower your phone will last a while. The phone always tries to get a better signal thus causing drainage.
Thanks dudes, good info

I have a stock Neo and found that battery life is nearly doubled when using 2G as cell standby use drops from 48-50% to 13-15% which I like.
I also have a -89 to -93dBm 10asu signal strength which believe is good.
But when on 2G there is no data connection, so does the Neo not have EDGE also is the phone faulty in respect to 3G data as I can only assume that is the cause of the poor battery.
2G normal uses less power, but if the 3G signal is stronger than the 2G one, I would use 3G as the phone has to use more transmit power to work with a weak signal.

I've got working, but relativly slow 2g GPRS (EDGE?) data transmision. I hate 2g lags (much higher ping) and when it is possible I use 3g or wifi. Maybe your situation is caused by your mobile operator.
I asked the question on sony forum and it appears that all xperia have this problem of no or very poor 2G data connection whereas 3G is there but results in awfully poor battery life.
Just checked about mast location and I'm about approx 700m metres from the the mast.
I have just walked to the mast with the Galaxy W and Neo and both phone signal strength increased the same and at 100m they were -52dBm.
re op your comments still do not explain why the Galaxy W has twice the battery of the Neo when using 3G, my conclusion is that SE are rubbish at 3G.
From my walk I would also say that with a -70dBm that you are 200-300m from a mast, apart from the terraced houses (no high rise/flats ) it is level ground to the mast.
Just to add my phone on GSM only shows gprs not EDGE
If i use 3g or 4g as phone signal without data activated, it will drain more battery than using 2g signal without data?
