OK got my galaxy however got some concerns regarding the constant network switching from H to 3g. I know am in a area of very good network coverage so that is not the issue but I have noticed my phone keeps switching between the H and 3g. It seems to change to H when the a connection is required for instance now as am typing its on 3g, however when a data connection is required it then changes to H, however as am typing it sometimes just switches to H even though am not using the data connection. I can probably see the logic here for the phone to switch to H when a data connection is needed but am thinking all this constant switching must somehow impact on the battery. Av, always used the app by Philip Mangelow the network app, to set the phone to gsm auto prl, which apparently is the best setting to use as it stops the radio from constantly searching for the network, however the same app, won't work on galaxy. Is their any code or tweek required to enable gsm auto prl.?
Yup, this happens on all phones I have( DHD, Nexus S, SGS2).
It will show H or H+ (if you have HSPA+ coverage ) when its actually downloading /uploading data. There was an article on the web that explained why its done. I will search for it again as I didnt bookmark it. But this actually increases the standby time of the phone and reduces battery drain.

Cheers matey looking forward to seeing that article cause have used quiet and few android phones and never had this before, and if it's good for battery then fine but would still prefer to set that gsm auto prl setting so if anyone has any suggestions please.
Exact same problem here! the strange thing is my SGS1 was always on H.
getting same, mine goes on 3g then changes to H, I think this is draining my battery, i full charged phone overnight and took it of this morning on 100% i went on XDA app for about 20 mins and i used 6% battery life just using this and nothing else. that to me seems like a huge drain
I set a toggle switch to turn off data when not needed? This may help in battery life, but im not sure why it keeps witching from H to 3g?
I suppose its not a big deal i guess, it doesnt seen to affect my battery life.
ok, surely this cannot be good for the battery, i have noticed, whenever, i unlock my phone, it shows H high speed, but when unlocked it goes into 3g. Surely, the phone is supposed to be on 3G when screen of the H, when i turn screen on to use it?.

Up until yesterday i was nearly always getting then H (hsdpa) icon on my Hero. Now im getting the 3G icon. But when i use an app that required the data connection it changed to H. It's annoying because it takes around 5-10 seconds to change and while its changing the app doesnt seem to have any data connection.
Does anyone else experience this? And can anyone tell me why up until yesterday it was always H and now only goes to H when the data connection is needed? I haven't changed any settings or installed anything in the past few days.
It may just be your providers local cell tower that is having issues rather than the Hero. Drop them a call first to see if there are any reported problems.
According to my provider theirs no issues in my area.
I just dont understand how mine can change from always being a H to being 3G changing to H when i use data. It's really annoying because when i open browser it takes around 10 seconds for the 3G to change to H and in that time no pages load. Then if i stay on one page for a while and move to another the H has gone back to 3G so takes another 10 seconds to change.
Could anyone who gets the H symbol please do me a favour? When you wake your phone from sleep is the H symbol always showing or is it sometimes 3G changing to H when you use any app that requires data?
Thanks
I think my H icon works as it should here in Finland. H is shown only when some data is being transferred, hence it is not always being displayed when I wake the screen. Sometimes it is shown, but I think then some widget or FB integration or something like that is being updated / synchronized.
I really feel that this is correct behavior, HSPA would suck your battery dry quite fast if it would be always on.

I think your right with it being the correct behaviour. Even though it takes an extra few seconds to start the connection when browsing etc it does seem that my battery is lasting longer. Now if i could just find a way of getting it to display 3G instead of H when away from my house.

I think there's no way of crippling the HSPA functionality of the phone, phone makes the selection of using HSPA (or not) based on network's decision (decided on coverage & various measurements) and capability.
Have you guys ever noticed your phone slowing down as it constantly switches between 3G and 4G? Living in Austin, I probably make the switch a few hundred times a day, depending on what building I'm in, and where my phone is sitting.
There are plenty of times where I pull my phone out of my pocket, and it's very warm, and running horrendously slow. I typically notice the 4G icon, so I disable it altogether. Usually within about 30-60 seconds, my Evo is responsive once again. I have used every stock ROM, and about 6 custom as well. All behave IDENTICALLY.
I really have had only one instance where 4G was useful, and that's when I was at a restuarant, and I wanted to tether my laptop. I was able to get a solid 4G signal, and it seemed to work great. I did find out, however, they had free WIFI, like almost every business does these days.
Not so sure I'm really sold on the 4G stuff, even though almost everywhere I go in Central Texas has good signal. It seems to waste far too much CPU as it switches back and forth, enabling/disabling radios, or whatever. If I'm in Dolphin browser, and it switches radios, the phone appears to lock up sometimes... quite annoying... happens all the time.
Anyone else with similar issues? I know most people aren't even in 4G areas though.

Well in general I noticed this cpu spike on my sense roms even when it was turning 3g back on after leaving a wifi spot. I really blame HTC's inneficient code, since CM6 handles this so much better. I did try 4G out in my area and thought it was better on my cpu than 3g was though.

After you use 4g, you need to reboot your phone. The 4g icon may go away but the phone is going to keep searching for the 4g signal. Known issue/bug. You can ssearch the forums and find lots more info on it. Free app called alogcat will show you this by conintuing to try and connect to winmax.
I live in Austin, too and use the 4g toggle quite a bit, especially closer to town, while at concerts or football games.

That explains why when I leave 4G on regularly, I have to reboot my phone at least once a day from slowdowns... If I leave 4G off, I tend to last almost a week before I get frustrated enough to reboot.
Really disappoints me, and I was hoping I was an isolated example. I had done several searches for this, and didn't see any results. I guess because not many people have 4G, and those that do probably toggle it on specifically for use when they are in a 4G area. Seems to me that 4G is only useful when you are sitting still... if I am in the car and I leave it on, my phone get sluggish as hell, and my battery can be dead in under an hour.

I believe the bug only occurs if you have a 4G widget on one of your home screens. You may be able to remove it and turn on via settings as a workaround.
Correct. Don't use the widget to toggle 4g. Go into settings and turn it on that way and you wont get the lag.

I had a ROM a few weeks ago that didn't even have a 4G toggle... I think it was AOSP. Didn't like it much and came back to Sense-based. No effect on the CPU bogging.

Only turn on 4G when you are actually going to use it than turn it off. Most web tasks do not require 4G and it will improve battery life.
theres a couple guides out there for editing your 4g in and out times, signal requirements log in delays, ect. those will help big time, and you should be resetting your phone once a day anyway for good usage, also it helps to if your using 4g, turn off the mobile network because its pointless to run both radios at the same time [helpful if you have myns with the data in the notifications menu for easy chaning]

Can you confirm that turning off the mobile network from the power-button drop-down menu actually does anything? On my phone, when It detects 4G or WIFI, the 3G icon disappears for a bit, then turns into the new one. That leads me to believe that it automatically does that for us...
I use 4G every day. I have "mobile data always on" set to on demand, so when I turn on 4G via the Extended Controls widget I use, 3G automatically turns off. Haven't had any phone slow down since I started using this method. When I turn 4G off, 3G automatically restarts, so one or the other is always on. I keep 4G always on at home, and only turn it on while out if I'm watching using large amounts of data.
At some point I made some changes in how long my phone will try to stick with 4G when there's a strong 3G signal, and that helped with streaming music/data while on long drives.
The only time you should see CPU usage is when the radios are toggling on, and off. Also when you turn 4G off, yes if you look in logcat you see that WiMAX is doing something but that's about it. IIRC it is checking the status of the 4G radio to see if it is on. The radio is off though, verified by monitoring the current drain in almost real time. The 4G radio draws about 200-300mA itself. The "4G Toggle for EVO" app by Jason Calhoun (see Market) so far has given me the least amount of hassle of the 4G widgets out there, and most of the time I don't have to worry about turning off 4G after a reboot.
On average with my current configuration I draw about 254mA (3G /display @26%/doing nothing), 188mA on WiFi. The lowest I've seen was 89mA (just coming out of sleep), and the highest I was ever to draw was 996mA (everything on, turned up, playing Angry Birds).
Under 4G settings make sure network notification is unchecked, if not the phone is forever scanning for a signal, especially if you're toggling bad. If you have it unchecked even when you use the widget it will only search the initial time when you turn on the widget. Can't say this will solve the issue, but at least stop the phone from continuously scanning for a signal should help. You can only uncheck network notification while 4G is checked. Hope it helps cause i'm in the centex area also(Waco). It helped for me when told to me by EVO owners.
Sent via HTC Supersonic: EVO 4G
I've also noticed my Evo seems really sluggish when 4G is on. Like, to the point that I always leave it off, because it makes my phone barely usable sometimes when it is on, even when I am standing right next to the 4G tower. I read through here and I'm going to try removing the HTC widget for 4G from my home screen, maybe that'll help.

But until/unless you reboot the phone, the WiMax continues to check the status of the 4g radio. So that would make the phone sluggish. Even with no toggle on a home screen or any screen, just doing it manually, when turned off it keeps scanning. Right Thats what alogcat shows until the phone is rebooted.
I have turned off 4g and gone about my business and been fine - went almost 30 hours on one charge and had 4g on for about 2 hours of that, so it may not be a major battery drain amp wise, but it appears to continue to scan even when turned off.
From a 2-day trial I can definitely say that my phone seems much more responsive since I removed the 4G widget. I replaced all the HTC radio widgets with the stock android one (which, of course, doesn't have 4G) and my phone seems very responsive. At the same time, I turned on 4G via the settings menu and I've left it on. It seems to be working well.
KE7 build + KE4 modem: No longer dropping from "H+" to "3g" when idling!
Have you guys noticed this? When my phone idled with KDD/KE1/KE2, it would idle with "3g" icon displayed. With KE7, it now idles with "H" displayed instead. From what I can tell, coming out of idle to "H+" is much faster now when you trigger demand for a data connection.

Mine didn't change either. Maybe OP's got something running in the background that's keeping data awake.
For the first since ive had the phone, its showing 'E' icon, had g/3g/H, but now its showing E in my flat. Had phone two weeks.

Nope, nothing running in the background. And, nothing is using the data stream as none of the arrows are lit up, it's just idling on H now vs 3g like before.
When I do initiate a data pull (ie, forcing an E-mail sync), it still jumps to H+ and the data arrows light up. Once done, it jumps back down to H to idle.
Really strange as I've *never* seen the H before... only 3g or H+ in my area.

Read my response above, there is no activity when idling in H. When I force data, it jumps to H+ and data streams light up.
Again, the key point to my post is that I've never seen H before. With previous modems, it was all H+ or 3g only in my area. Something definitely changed from KE2 -> KE7 for me at least in the Austin area, just not sure what the change means.
Mine still idles in 3G and switches over to H+ as needed
mine idles in 3g and when in use H isn't it to save battery
In an ideal situation..a phone should drop to 3g when data communication is in idle and stays in this standby mode until an application starts transmitting or downloads data..than the modem goes out from standby state and grabs the highest connection available 3g or h or h+ depending on network and signal strength.
By operating this way the phone dose'nt waste precious power maintaining high speed connection during idle/standby state..
This info was given by friends working in telco companies..How samsung writes the software for the modem to behave is a different story.

Much better this way. Saves a lot of battery. I don't think that its guaranteed when none of the arrows next top the network icon are lit up, no data is being transfered.
Sent from my Samsung Galaxy SII with XDA Premium
i'm not sure where the idea came, but there is no battery saving from having a phone idle on HSDPA or idle on 3G. its the same battery with both. i guess i can see how one would make that assumption, but its definitely not true
Well here's the thing. Around my house, my provider has excellent 3G coverage, but inside my house its not so good. I get full 5 bars of "H" at about 200 meters from my house but only 2-3 when inside my house. Its OK by me. The thing is that when i come home from outside the data coverage is H with 2-3 bars. If I am at home and turn off/on the 3G option on my phone it just goes to GPRS with full 5 bars signal and never on 3G/H. I would prefer the H than the GPRS. Is there any way to have it lock into H and not on GPRS? Maybe a registry tweak?
Thanks in advance.
I have had this issue for a while, and I still don't have any way to force it, but if you find a way I'd be interested.
The only trick I found is not to turn off the 3g but to hit "tap to select" on the Network Selection option, and then selecting my provider again.
In the states AT&T has two selections AT&T and AT&T DR. Not sure what DR stands for but usually toggling between the two will get by back to H. That or sometimes just powering off the device.

Hey guys found the solution to lock the wp7 to 3G/HSPA only network.
1. Press ##3282# and it will open the field test screen.
2. Select settings at the bottom of the screen.
3. Select 3G Network only option.
The phone will be locked to 3G networks only even if the signal is very low.
Tested on HTC 7 Pro. Working like a charm.
Hope it helps.

Eυχαριστούμε! Τhanks!
So.... Two minor issues with the work around.
Went to my friends house, an area I know I always have a bad connection. There was no 3g signal so it basically was stuck on no signal the whole day.
Also, went into battery save mode which auto-disables 3g, and it do go to 2g connection. When charging the battery back up it was still on 2g, had to toggle the cellular connection again to find 3g, but seems to be staying at 3g for now.
I'm having issues too
I'm also having issues in Italy, with Vodafone operator. I've posted a video to youtube that shows very well my problem. Please watch it and tell me if you have the same issue (endless switching between 3G and H having very unstable data communications). I'm thinkinh about returning back to repair for the second time...
While I can't read much of what you wrote, I can tell you for a fact that Battery Saver mode does that to my phone. ...
The fix posted above works, until battery saver kicks in, then all is lost.
Aside from that, I just know I'm in a bad area sometimes so it will switch, but for the most part I only have that issue when I turn on battery saver.

Is that actually supposed to happen? I haven't read anywhere that battery saver turns 3G off. That's not my case, at least.
In the video I had battery saver on, it's true. But the same happens normally even when battery saver is off.

You know, that was an option pre-mango in the battery saver menu.... I guess I haven't checked it in a while. That or I'm just losing my mind, which is entirly possible.
That said, I have found my setting that the earlier post randomly turns to "2g only" usually after battery saver is turned on, but it seems to be triggered at random. Not sure if there is a regedit that I can do to stop that, but for now I just go into the menu and change it.
I've had my phone for over a year now, and I love it except one strange quirk. I'm with T-Mobile in the midwest, and whenever my phone says 3G, no data works. Everything is fine when it says 'H'. When I'm browsing the internet, I see the status shifting from H to 3G every 30 seconds or so for a duration of about a couple seconds. When the phone is on 3G, the website stops loading, and no data works (even syncing with mail stops). The second it switches back to H, everything works 100% again. Anyone know what's going on with 3G?
Another example is Youtube buffering. When the phone is on H, I see the buffer bar fill up. When it switches to 3G, the bar stops. When it switches back to H, the bar moves again.
I love the HSPA speed, but having it cut out completely fairly often has become a huge annoyance.
Found another thread that had the same issue:
http://forum.xda-developers.com/showthread.php?t=1069844&highlight=3g+hspa
But the people there weren't noticing any lag at all while on my phone, there is clearly no data transfer occurring when the phone displays 3G. Also, if this is indeed some sort of power save feature, shouldn't there be no flopping if you're actively browsing? I see it switching fairly regularly while browsing/downloading, and data completely stops when the phone switches to 3G.
Found a few other threads suggesting to set hsxpa=0 in the build.prop.
http://forum.xda-developers.com/showthread.php?t=911728
http://forum.xda-developers.com/showthread.php?t=963780
However, once I did this, I still get the H/3G flipping which is odd since I thought the hsxpa=0 would disable H? What's going on here?
Played around with the numbers, and setting it to 1 forces 3G mode only. Hope this helps anyone else!
