I work in a building that is well shielded in most places and get no signal. My phone drains incredibly quick when this is the case. Is there a way to reduce the polling frequency that it looks for a tower to stop this? I thought juicedefender might but I can't figure a way to do this.
Rom: Fresh 4.0.0.4b
Kernel: netarchy 4.3.1.4 cfs have no sbc
hw version 0003
juicedefender ultimate
setcpu 200-1152MHz, smartass governor
Thanks!
When I'm in an area where I roam or have very poor signal I notice increased drain rate as well. This was the same with my TP2. I've always just understood that when the phone is constantly seeking signal and cycling back and forth between roam/3G/1x the battery drains faster.
Your best option, is to utilize "airplane mode" when you know you're going to be in an area that had no signal/you won't be able to use it. I hate to do it because I don't like my family not being able to reach me in case of an emergency, but it is one option for you.
I second the airplane option. Also, WiFi is available while in airplane mode. Perhaps your building has WiFi you can connect to and you can keep something like AIM or Facebook or Google Voice/Talk open and instruct those who might need you in an emergency to reach you through the method of your choice so that you may call out from a landline or step away from the building if there is an emergency.
Just a thought.
See if you can get in on the new Google voice option where you can make your sprint # your Google voice number. Once you have done that you can have your work # as one of your forwarding numbers if your work allows. Or airplane mode with a 2nd charger for work.

Yep, Airplane mode is the ONLY way to turn off the cell radio. Otherwise, it will be constantly polling for a tower.
Dial ##3282# from a froyo sense rom and it will bring up a menu where you can change how often it polls the tower. It's Going to affect how long it takes your phone to receive calls though.

If you know you're not getting reception, why not just use airplane mode? I mean, if you don't have reception you're not getting contacted anyway.
If you want to go the airplane mode route, Tasker is a great app that lets you control lots of things. You should be able to turn off your radios at set times during the day and have them enable after you get out of work.
I just loaded the 2.1 EPST and run a Verizon PRL when I am at work. I get a crappy Sprint signal at work. However your issue seems to be different as the walls/windows may be blocking all signals? Verizon seems to penetrate better though.
With Tasker, you can also set your phone to airplane mode during work hours, but automatically turn it off and enable data every fifteen minutes (or however long) to check for text messages, voicemails, etc. That is assuming that you get any signal at work... if you don't have a signal at all, just turn airplane mode on yourself.
To answer your question:
Yes, not having a signal will drain your battery. The phone will keep increasing the radio strength to lock onto a tower. Opposite is true to, if you have a strong signal, the radio will decrease the power level thus saving battery power.
You might want to contact Sprint ([email protected]) and let them know that you don't get service in your work building. They gave me a airwave device, but have to have Internet connection for it to work. The only other option might be to have some type of power booster/repeater that are typically very expensive. Not sure how your employer would feel about these suggestions - but never hurts to ask.
I am military and work on a base. The entire internet is locked down except for official military business, so an Airave device wouldn't work.
No internet, no cell signal and neither AM or FM penetrates. Maximum pain.
I'll try tasker, thanks guys.

In that case, if you don't already have Tasker, I'd just turn airplane mode on yourself when you get to work & turn it off when you leave. Or there are free apps that will do it automatically that aren't as complex as Tasker. Unless you find another use for it, then go ahead.
Would roam control work to try verizon towers? I think they have a stronger signal locally.

LOL you said it yourself. If the military doesn't want you getting signal, you're not getting signal. In general, if you can't get radio signal you can't get cell phone signal. Early cell phones operated on FM (type: frequency modulation) radio and what we're using now is basically a digital-type FM radio. In the end it's all EM waves and you're likely in a giant Faraday cage of a military base. I say avoid even trying to fix your problem and just go airplane mode.
Hi. I have the volume bug and not sure if this is related but i've noticed that I can hear interference during voice calls very faintly in the background. I'm on Vodafone and have only noticed this at home where I only get 2g coverage. I have WiFi on but dont know if thay makes a difference.
Anyone else hearing anything during calls? It's the classic cellular noises a bit like the built in radiation ringtone.
If you use wifi at home for data connection you could try the following thing.
2G gives trouble as you know...
In the phone application type *#*#4636#*#* touch phone information, set it to WCDMA only and see what happens and if it gets better with calls, maybe you lose the complete data connection and you have to put it back on where it was, I disconnects de the radio for a couple of seconds when it reconnects to the provider )
This forces not to use 2G networks, so there is no interference of this source.
Maybe it helps? it's just a thought

This will not fix anything especially as he specifically stated that he only gets 2G coverage at home
also, as I have already pointed out in another thread, that option does not stay persistent (at least in my experience)

For all those people who are saying that you can force the phone into 3G only mode - I have some news for you -
It doesn't stick.
Try it yourself.
1. Go to the phone application
2. Hit *#*#4636#*#*
3. Select Phone Information
4. Scroll down until you find Set preferred network type
5. Change it to WDCDMA only (or indeed anything other than GSM/CDMA Auto PRL)
6. Now reboot your phone
It doesn't stay persistent.

But you don't make phonecalls over 2G are you, if you're on 900Mhz provider this will use gsm signal to make calls isn't it?

you are incorrect - if your phone is in 2G mode (either due to forcing it into 2G mode via the settings option, or by being in a non-3G coverage area) all communications are done over 2G. This includes SMS, cellular calls, and mobile data access.
Ok, did not know this, and wanted to know.
Is this the case everywhere or a standard in mobile communications technology?
So no chance that GSM signal is stil there and works if you don't get 2G data connection?
Did not see my GSM signal drop out when 2G was available.

If you can only receive 2G connection in your coverage area, you will not be able to make calls over 3G.
Hey so has anyone else noticed this issue? As I mentioned, it's very very faint - as in you have to be in an otherwise silent room to notice. And it occurs when I have 3G too i've noticed today.
Some more detail:
The noise doesn't start as soon as the phone connects - usually a few seconds afterwards and it actually continues for a couple of seconds after i've hung up (which I've noticed if I put the phone straight back up to my ear).
Would someone else mind doing a test call in a very quiet place and letting me know?
Hi guys sorry to bump this but quite concerned that it's only my phone this is happening to. If someone wouldn't mind just listening carefully during a call (maybe to your voicemail to avoid the weirdness!) in a quiet room to let me know if they can hear interference that would be great.
So this problem frustrated me so much that I got the phone exchanged. Guess what though - same problem.
Surely someone else has noticed this - if you're in a quiet place it's both pretty loud and very distracting.
As I originally explained - after a few seconds of any call, I get a very short mute (we're talking microseconds) followed by the kind of background buzzing noise you get when you put a phone near a speaker.
Could it be down to a faulty batch?
when i am on a call i cant not see to get data...the data connection turns off by itself and when the call ends data connection will come back on? is it suppose to be like that or is there something wrong with the phone. right now im on software 1.28.708.10. thanks

Happens to me too I believe my frined.
It only happens with mobile data though.
If you are on Wifi, the wifi should NOT disconnect right?
ya if it is on wifi then it is ok. not data connection though
I believe that the phone switches to 2g during calls, and not sure whether this is a telco setting that they do not allow calls through 3g, or a software feature of the phone with the reasoning that 2g signals are generally stronger in most parts of the world compared to 3g.
Just fyi i had the same issue on my "old" Desire HD.

It might be carrier specific. I have no trouble getting (and keeping) HSPA data when I'm in a call.
which version do u have Barry? I am using the international version on rogers. Are you using the at&t version?

Then I believe it to be carrier specific then since the software governing these kinda things should be standard across the board

Ok that is so strange. I have the Hong kong version on rogers network. It never happened to me before and I have used a lot of HTC and unlocked phones before.

ok so i dont think its the carrier cuz i reset the phone and it works sometimes now. if i make a call and browse right away then it will work but if i leave it for too long then it wont work.

guys its because the phone calls you make are on a 2g bandwidth unless its a video call, that's why if you have 2g connection or EDGE active it will get disabled as soon as you make a call.
to clarify, force your network settings to wcdma and then connect to 3g, after that make a call and your 3g will not be disconnected

i tried this and the 3g was displayed in notification bar.. but when i use this as hotspot, i hardly get connected to internet in my laptop (connected to phone) even the 3g was displayed.. this is really bring me down.. as i need to use hotspot while on travel and had conversation at the same time..
is there any other way to solve this?
thanks
Yup got it to work. Thanks.

Hi Marktang... I saw your post from Google as I lost data connection during phone call with my Galaxy S2.
May I know is it after configure the Network Mode inside the setting to use WCDMA only, then the problem will be solved?
Thank you...
I've found that this phone's ability to transfer from 3G to 4G data is absurdly slow, if not completely useless. It also seems that it will never switch if there is data transfer in progress. The only reliable way to make it work is to airplane for about 10 seconds, then turn it back on. If there is 4G coverage, it will come back on immediately into 4G. Now that I think about it, the same thing seems to happen going from 1X to 3G as well.
Example of a common daily routine... When I leave work and walk outside, there is full strength 4G. But the phone will be sitting on 3G from when I was inside. It will not switch to 4G unless I airplane it first to cut it off and back on. The 3G data here is literally like a dialup 14.4 modem. So it will just sit there trying to sync or do whatever its doing until the cows come home. It will never change to the readily available 15mbs 4G data.
It is so bad, I had to make a tasker function to airplane, wait 12 seconds, and turn it back on. I made it a widget called "Reset 3G/4G".
Any way to fix this crap?
Sorry if I missed it but are you stock? Or are you rooted? Or are you rooted and running stock/custom ROM? If so, what ROM?

Rooted with the FreeGS3 ROM.
My EVO had the same behavior where it wouldn't switch from 1X to 3G if there was active data transfer. Which makes no sense. That's like not changing lanes on the highway because you'll have to look in the mirror first.

Maybe not, but the phone has to pause the connection, disconnect one radio, start up the other, wait for it to be on, connect using that radio, and then finally resume the data transfer.
I don't expect it to happen in a matter of seconds. But what you describe should not take 5, 10, 20 minutes to accomplish. It will not switch between 1x, 3g, and 4g so long as there is data transfer in progress.

True, but it may just be the apps blocking it. If theyre using it, the connection wont get dropped until it goes inactive, if I remember correctly
Here's why that makes no sense. App needs data connection. Phone in 1x with a 20kbps connection, trying to download music or photos. 3g or 4g is available. But instead of switching to it, it will just sit there until the app crashes, or tomorrow when it is done downloading.
Hmm... I'm on stock rooted MB1, and I'm also roaming at work, but there's a somewhat reliable LTE signal right outside the building, and as soon as I walk outside, I see my phone go from roaming, to not roaming, and then I see it switch to 4G in a matter of seconds. I don't need to turn on or off airplane mode or any sort of trick like that. Maybe it's ROM related? Custom kernel related? I'm not saying it is, I'm just listing possibilities.
Then again, I'm also not trying to download music or photos when I see I have a 1x connection, though my current ROM doesn't really tell me if I'm on 1x or not, so I just don't do anything network intensive when in low connection areas.
I just changed some settings in the ##DATA# menu. We'll see if that helps.
The tmobile service in my area sucks and it will stay on 4g lte even when I have a very bad connection which drops calls and gives me really bad speeds. Is there an app that will automatically switch lte/gsm/wcdma when the signal is very low so I wont drop calls, waste battery and give me poor dl speeds? Or is there anything else that I can do? Maybe with tasker or a tweak. I would appreciate any type of solution. Thank you.
Is there any thing I can do about this?
On stock Rom go to settings>more networks>mobile networks>network mode.
Pick the one you want. Probably gsm/wcdma auto connect.

Thank you for your reply. I already know about that option. I still want to have access to lte when I have a decent connection. Is there an app or a tasker configuration that if the signal is below a certain level it will switch networks? Also, which network it used to make phone calls? I thought all of them but my friend said phone calls are made on 2g. Thank you!

Is there any solution for this? Also when you are connected to lte are you still making phone calls through 2g? Thanks.
Is this a problem near your home? Can you use wifi calling to help fix the dropped calls? Not sure about how to get the phone to switch from LTE to 4G when the connection is poor. I do it manually right now because my LTE has been acting a little wonky lately where it won't even connect to LTE and leaves my phone in network limbo unless I force it to use 4G. I'd like to see a solution to the LTE - 4G switching too.
Last i recall, there is no tasker or app capable of doing such a thing like switching network preferences. It goes against "policy" per say. But your friend is right about calls being made through 2g. That is how you are able to use data whilst on a phone call. The data is being used through 3G and up, while the call is being used on 2G. now i am not sure about T-Mobile's "HD Voice" calling, that is prolly LTE.
I myself have looked through every single API google has trying to write my own app to change the network preferences and could not find it. There may be an option through root though. Havent found it yet.
Correct.
Calls - 2G
Data - 3G+
