I was wondering why someone would want to be connected to 3G all the time for talking. I could only guess that it is somewhat better quality. In my case I don't see it that much. I do however know that it waistes about double the battery using 3G all the time. If I am not using data is there any real advantages of it? and what if I am talking to someone who does not have a 3G phone.
Thank you,
Hmm, of course I could be wrong (but I doubt it), Data and voice are 2 different things. 3G is data, voice is voice.
Thats what I was thinking, but I dont understand why it would be connected via 3G all the time if im not even using the data. and 3G and EDGE connections seems to have different signal strengths. If it's only for data I guess I will leave 3G off all the time.
3G signal is emitted on a different frequency than GSM/Edge signal - it does drain the battery faster and is pretty useless if you are in a well covered GSM area and only using voice (phone) function. The quality gain isn't significant enough overall to make it worth battery drainage on a device like the Kaiser/Tilt.
The advantage of 3G is its data stream but it's also good with voice for hard to reach areas only reached by 3G signals - those are rare nowadays, especially in the US, but in some cities with landscape blocked coverage (like in some skyscrapers in Manhattan for example) you might not pick any GSM network at your work desk but might pick up 3G - in such places, using "bandswitch" regularly makes sense.
Lastly, 3G signal is slowly replacing GSM/CDMA (2G) as the broadcasting standard so I wouldn't be surprised that in the next 5 years, more and more GSM phone operators will stop mantaining there GSM frequency towers in favor of 3G.
Thanks jonas that's the answer I was looking for. I will use edge untill my signal gets low.

Interesting, since that means AT&T has a lot of work ahead of them and better get their butts in gear rolling out 3G. I live in the whatever-it-is, 90%, of the network area that does NOT have 3G.
Or I suppose I could be an optimist about what you say, and think that maybe it means AT&T really will be accelerating the rollout of 3G. That would be nice given the snail's pace of 3G expansion in the past couple of years.
Over in the UK 3G is the standard 2G is still available but the telecommunications offcom have required all UK operators to offer a minimum of 90% 3G coverage by 2010
I've always heard that Voice on 3G uses less power on standby and when talking, but I might be remembering it wrong.
Data on 3G uses significantly more juice than EDGE does (over double in my experience!) but I don't think you'll see a significant difference without data usage on 3G vs GSM but I could certainly be wrong.
I always have FlexMail and IM+ running, I haven't compared battery usage without them yet.
One big advantage that 3G has over EDGE is you can do voice and data at the same time. I've heard varying stories about some phones can do it on EDGE and some can't, but I know on my Tilt my connections die when I'm on a voice call and reconnect after but does not on 3G.
The biggest advantage of 3g besides the penetration is that you can talk and maintain a data connection. Edge gives you one or the other at a time--data or talk.
My carrier had some little problems during the past weeks, aparently they were working on something. I sometimes, for short periods, did not have data connection or no servic at all. Now the problems are gone and a speedtest today showed that at my home, the download speed went from an average 1 Mbit to over 5 Mbit!
However, the H symbol won't go away anymore! It used to switch to 3g when not data was transferred. I assume that this will influence battery life.
Is there anything I should be worried?
From what I recall, H is faster than 3g, as long as your in a good signal area, the H will always be visable, it will only drop down to 3g if the area your in has no H signal... and if there is no 3g it will drop to a 2g signal... simples, having the H does not meen that data is being transfered!
I am aware of the different speed levels, what I experience now is that the H symbol stays all the time, whereas it used to change to 3g when idling even in areas with very good reception...

Wait, I don't get what you're saying. Let me clear it up:
Very good reception = H
Not so good reception = 3G
You want to see H (means HSDPA which is a a type of 3G data, but it's faster).

Okay, I'll try that too!
I live in an area with very good reception and therefore the phone used to switch from 3g to H whenever data was transfered and back . Now, however, it stays on H all the time and does not switch back to 3g when no traffic occurs.
It is just a change in the pattern my phone behaves so I wanted to get some info on that...
Hi, it's your phone doing what it should by seeking the best signal.
H refers to HSDPA which is based on UMTS (3G). Consider it a 'turbo' version of 3G. It's sometimes also referred to as 3G+ because it's faster then 3G but not really 4G technology. The tower in your area most likely got upgraded to HSDPA that's why you don't see the 3G icon anymore.

Not correct, he mentioned that his phone was using H on demand before, so the capability was there already.
The problem is that H mode uses more battery than 3G, which is why it normally only switches to H during data transfers instead of continously being on.
Possibly your provider made a change which forces your phone to stay in H mode. On hardcores homepage (see speedmod kernel thread) he describes a method to manually deactivate H mode if you want to play with it.
Hope that helps.

seems to be the explanation... Suddenly I have ~6 Mbit, so almost unsurprisingly there had to be a catch
as for disabling H, it would be permanently so not quite an option. I guess, I'll have to live with it but nevertheless I'll call customer support..
Hspa and 3g are actually different technologies, but can be used on the same site and freq. If you have noticed that your phone is nowdays all the time showing H ( hspa ) and not in 3g like before it means that your carrier has expanded their hspa features and capacity of the network on that area. Main difference between these two tech is of course the speed and how network resources are shared between the users. In 3g you have dedicated ones, but speed limited and in hspa you are sharing the resources between other ones under that cell area. hspa is good if you are near by the cell and there is not too many users from battery consumption point of aswell from througput point of view, 3g is better if you are on the cell edge due to dedicated resources reserved only for you. Main point is, battery consumption of your phone depends mainly how you use your phone ,what kind of applications you have and how often those are connecting/contacted by the network.
Browsing in 3g sucks!

I have already disabled fast dormancy using *#9900# code in my Note, but now my phone switch between H and H+ icon. When connection is idel, it falls back to H. If I browse a webpage, it takes more than 10 seconds to connect to H+. And yes, H has no data trafic avalable. That means I have to wait the phone to change to H+ if I want to browse the internet.
Does anyone know how to stay with H+ icon?
OMG no one knows?
I think it depends on your rom..

It depends on your Network and rom + modem u using.
Post the details here and lets see what the community here can find.
Data works fine on H. It certainly seems faster on H+, but, as you say, the phone spends so long finding and connecting, the speed is wasted. I'd be happy to stay on H myself.
I agree, it would be nice to keep to one. My connection jumps from 3g to H to H+ and even to E, especially when moving on a train.
I think it is network dependent
E - Edge 2G
H - 3G
H+ - 3.5G
When you set your network mode to auto, it searches for faster avaiable network. If you set it to only WCDMA, you won't get E, but i think there is no setting to select 3G/3.5G.
Another problem to select WCDMA is, whenever any place dont have 3G coverage, your network will lost.
In germany it is also other:
G - gprs up to 56kpbs
E - edge up to 128kbps
3G - umts up 384 kbps
H - HSPA up to 14 mbps
H+ - extended hspa up to 21mbps
But H+ is only active when it is needed and it is all carrierer depending. If i am on H+ i can se my battery dying

It is network related there's nothing your phone can do about it.
H+ is actually using the 64QAM modulation over the air interface which gives you 50% more throughput ideally than H.
3G is up to 384kbps
H is up to 14.4Mbps (16QAM)
H+ is up to 21Mbps
The above is the throughput on the lower levels, so at the application level you will get around 10% less (and that's if you are alone using the base station and your carrier is not limiting your throughput)
Everything that goes through wireless interfaces has to be shared between users. Therefore, the network has to manage valuable and limited resources to serve everyone and provide a best effort service. In order to do that, idle users or users below a certain threshold will be down switched from H+ to H (this usually happens due to radio signal conditions) and to 3G. After that it kicks you back to idle mode, so even if it says H, your actually not connected until a new session is triggered and based on your needs and availability, you are up switched to a faster channel.
Depending on each country and their marketing:
2G
2.5G is GPRS (G)
2.75G is EDGE (E)
3G
3.5G is HSPA (H)
3.9G (4G in the US) is HSPA+
4G is LTE
Fast dormancy is a new feature on 3G networks (not available in most networks yet) that improves your switching between different channels (H+, H, 3G, idle, ....) and it has a major impact on your battery life and the speed of establishing a new data connection once you are idle. This is also controlled by your network. Anyway, some people believe that turning it off while it is not supported by your network can help improving battery life. Which I don't think is true, since by turning it off you are forcing your mobile to ignore this new feature (and if it doesn't exist there's nothing to ignore anyway) and turning it off shouldn't have any effect unless it is active on the network and your carrier is not managing it correctly.

There is a short code for turning off h+ my phone would always time out when trying to connect to h+ so disabled it. And it works great now, can't for the life of me remember what the short code is though!

Is there a code to turn on H+ too? Because my phone used to show H+ but now it only shows H although I have not changed any settings.
Hi guys!
I just got my contract with mobile internet in it.
Each month, I get 1GB of data and it's awesome!
But I have some questions/problems with it.
When I connect to the 3G network, I sometimes have an E-connection.
It's pretty slow, but I found out this is some kind of 2G netwerk (called Edge).
Mostly I get an H-connection (HSPA(+)) I think and that speed is fine.
But sometimes it changes from a fraction of a second to a 3G-connection.
I think that is what I really need, but how can I "force" it to always go to 3G?
My carrier supports Dual carrier 3G, so that "should" double my 3G speed.
It would be awesome if you could help/inform me!

H (HSDPA or HSPA) is faster than 3G is faster than 2G.
I also get switching from 3G to H a lot at home were signal is not good.

Hey guys
So I looked around the forum for an answer to this question and i found similar topics but not exactly what I was looking for. I have the HTC one with sprint and the only issue I have with it is how it handles its preferred networks. If have 2 bars of LTE but 4-5 bars of 3g its going to stay on 3g and not switch to LTE. Is there anyway to change how it gives each signal preference. Currently it will wait till there is no 3g signal before it switches to 2g but LTE is not giving the same preference. I know it's just this phone because I had the iphone 5 before this and when I was on campus at my university it would stick to the 1 bar of LTE i had rather than switching to 3g. If I force the phone in LTE only mode then it will pick the LTE signal but then I can't call and text obviously so it's not very useful.
There are two things that the iphone 5 did which I miss but otherwise love this phone. One is getting LTE in places that has low coverage and the other is roaming on verizon network on 3g. The iphone would always roam on 3g but the htc one only roams on 2g.
Is there a way to change those things with this phone? Thanks in advance!

Have you tried changing the preferred in the *#*#4636*#*# > Phone Information?
Hi thanks for the response. Yes I have messed around with that. That's how I got the LTE only option. It isn't a matter of not finding LTE signal. It's just the way the phone handles what is perferred. The phone first sees if there is a strong LTE signal and it catches that but the moment it goes to about 3 bars or less it will switch to 3g. I want it to continue sticking with LTE until the signal is gone completely like it does with 3g -> 2g.

If its that way then I belive a builder will be able to forge a flashable zip for that purpose.

I see. And who do I ask for that? Or how can I build one? Sorry I am a bit of a rookie in this. I don't want to mess around with it too much but can learn. I thought there might already be some sort of hack or a modded PRL.
any new insight on this by anyone? thanks
I have lte at my work if I do lte only but it will switch to 3g when i turn everything else one because 3g signal is stronger than lte. id rather use lte however but still have my texting and calling capabilities.

I know it's not an optimal solution, but have you considered using Google Voice integration in the meantime? With LTE only mode, so long as you're signed into an app of choice (Google Voice/Hangouts should be able to handle your calls and texts if you tweak at it a bit), you should have the desired service until you can get some dev help.
