My 3G and HSPDA Keep switching when there is an active internet connection.
when im not acutally using the internet its just 3G then when i search it turns H on is this some kind of power saving feature or is there a fix, as i would rather have H on always.
It's supposed to do that. HSPA is incredibly power-hungry, so would you want that?
Thanks for the reply mate.
There is an option to change it to use only H or 3G in the settings, if you really want to.

I did the kaisertweak to enable the H network or whatever (yes i don't understand it)
the network still says E or 3G . It said that all the time, for the last few days.
Then I was messing around trying to get this gps to work in google maps and I noticed it switched to H. but now it's back to 3G. is this all normal?
Ive noticed that too..
no idea what it means
what operator are you with in what country
check with them to see if you have hsdpa reception my hsdpa is enabled but since i dont have coverage i stay at 3g
hsdpa is a better version of 3g
its often called 3.5g 3g+ or mobile broadband so basically all the twaek is is to let your phone get the faster connection but only if your operator has the signal to do so
The H icon (HSDPA) is a step up from 3G it allows anything up to 7.2Mbs transfer but the HTC instead of contantly allowing this to be active thus creating massive battery drain only allows it when a data connection is active and data is being transferred any other time and you will only get G, E or 3G
3g alows ypou to have video conferences but H mean HSPD fast internet 3,6Mbit or 7.2Mbit depands that the difference i belive.
exactly just because you enable it doesnt mean you can recive it
I turned hsdpa with kaiser tweak also. I noticed it will only connect to hsdpa when transferring data (IE, emails, weather, ect.). Otherwise it will go back to 3G when on the today screen, or offline tasks. I guess its to conserve power?
Maybe thats what your seeing?
ok thanks, looks to be normal =]
just wondering coz of battery consumption issues. coz if i dont need internet i turn off 3g so its on edge on standby. but when i need net, i want 3g n hsdpa so was wondering if hsdpa only turns on when i also turn on 3g. thanks
3g will automatically connect if you enable it in connection settings unless you have change it to like your own network or something like that. someone correct me if im wrong. its been a long time since i use 3g.
from what i notice, if i leave 3g mode on, (even tho mine disconnects after 2 mins of idle connection), it uses up more battery than leaving it on edge on standy. this is from my experience at least.

It is absolutely true. 3G mode consume lots more power than edge. I had this experience too.
Back to the post question, hsdpa is one of several 3G standard technologies (with UMTS, for example), so speaking about 3G means also speaking about HSDPA. So it is enabled when your network support it and when a 3G connection is enabled.
Is that possible?
Do you mean you want to keep the phone on 3G/3.5G only? Why would you need to turn off GPRS?
Yes.
Because sometime my connection is switching between H and G themself. When that happens the download will be interrupted.
Hmm that's weird. The phone shouldn't switch from H to G. It would go H then 3G then E and then finally G. But to lock the phone in 3G only type *#*# 4636#*#* and then hit phone information and then scroll down to where it says preferred network type and choose WCDMA only. That will prevent the phone from switching out of 3G but if you leave 3G coverage you'll lose data connection because it won't drop to E or G
thanks!!!! )
Hey good thread info.
But I was wondering,
How can I turn on 2G (GPRS) so I only have Edge or 3G or WIFI
The reason for this is, when on GPRS browsing it doesn't allow calls though to my Nexus One.
Anyone do you know the command? to turn off GPRS and leave ALL other's on please
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.
Guys I have an odd problem.
Where I live, the signal on the HTC One switches erratically and constantly between H+, H and 3G. At every switch of course the data connection goes offline. It's driving me crazy.
Is there a way to force the phone to one of the three: 3G or H or H+?
Please see image 01.
I've tried going into *#*#4636#*#* but the choices baffle me (see image 02). I've tried a few of the available choices but it seems that 3G, H and H+ fall into the same category.
It's probably a dead end, I can't imagine what else to do ..... has anyone else had the same issue?
The 3G logo means it's on voice only, and H+/H means there's data incoming/outgoing. They're using the same radios and frequencies, it's more like an idle state when it shows 3G. 3G will still periodically go up to H+/H to check for any incoming data then goes back to sleep at 3G.
I have the same problem with my connexion. It is only stable when I have the "3G" symbol. I did not find a way to force "3G". It seems the switch to "H" is on demand...

It's normal behaviour, if you have a good H connection it will switch to this when there is data traffic but when there isn't it will switch between 3G and H
