no 3g (stuck on H) - Galaxy S III General

Okay guys, I'm running CM9 on my phone with modem UBLE6, and for whatever reason, my phone doesn't seem to "switch" to 3g mode when on idle. My first thought was an app is running and using data. I've check BBS and Bad Ass Battery and niether show anything with wakelocks and data usage. I flashed CM9 as soon as I got my phone, so I don't have any info about stock, but if it comes down to it, I could always flashed back to stock if needed. Is there anything else that could be cause this, or something I should look for? I feel I'm getting decent battery (about 1% drain per hour) but I'm sure it could be better if my phone would actually idle in 3g. If I switch to use only 2g it goes to edge fine if that means anything. Any help is appreicated.

3G/H are different from H+.
There is no difference in 3G and H, H is just a better connection of 3G from my memory.

I always thought the "H" symbol came up when data is being sent and the "3G" symbol came up when data is idle. Right now, my phone almost constantly displays "H" by the signal bars.

That means you have a solid connection to 3G. ATT phones will report 3G, 4G and 4G LTE separately. But H+ = 4G, and H is just 3G.

The Galaxy Nexus does this, but I have yet to see the S3 do this.
Also, 3G, H, and H+ are all 3G.

I guess I'm just used to my S2, whenever it was idle, it usually displayed "3G". If you both agree all is well, I won't worry about it

Like I said, you had an ATT branded S2, they did not tell you when you had 3G or H, only when you flashed custom ROMs, developers would fix this annotation.

3G/H/H+ all = the same thing at different data rates.

What Uses More Battery

3G or WIFI?
Sent from my X10a using XDA App
Wifi uses the most, then 3G, and then EDGE uses the least. Usually WiFi is faster than 3G for me though.

I guess there's some bug in the firmware then... coz wifi always drains the battery more than 3g for me.. even though I know its supposed to be the other way around
It should also be noted that if you're in a poor coverage area then flapping between 2G and 3G signal can be a real nice battery slayer.
At work we have some awesome dead zones that can nuke a battery pretty quickly. We always make sure to disable 3G if we sit around that area.... or leave a colleague's phone there if we feel like being a bunch of dicks

Battery saving idea

I've had my sgs2 for a week now and I'm very satisfy with this phone. No problem what so ever. Anyway, I know the phone has this battery saving feature, the data 3g stays at 3g and only change to H only when we download data. So I was wondering if it is possible to get the phone to stay at 2g then goes to H when data is in use? Maybe 1 of the developers here can do this?

There's an app for that. Maybe Juice Defender? Or something like that, it's one of those. You can set it to only use 3G when the screen is on, and then tell it to go back to 2G when the screen is off, so it isn't as power hungry, and slower data will come in, but it's worth it.
Last night I go to sleep around 1:00 and the battery was 94%. This morning in 10:00 the battery is 90%. I doubt, you can save more then 1% using such app. The only thing that I did is to disable wifi in sleep mode.
Juice defender turn off 3g data when you put the phone to sleep. When you turn it back on, the phone stays at 3g. What I'm try to say is maybe some sort of app that force it to 2g then automatically turn 3g when data is in use. So lets say, I open a web page at 3g speed. after I've found an article I'd like to read, the phone automatically turn to 2g.

By the Way is it possible to only use H+ and to deactivate 3g completely ?
Come on dude 1% is a little right? My sgs2 also has this great battery life when put to sleep. But the problem with our android phones is when we use it continuously. Now obviously from what you are saying, I can tell that your gs2 is in sleep state most of there time. Imagine you spend 30mn reading some threads at xda, watching a movie our listen to music or sending emails..... how much battery life we can save if the phone was in 2g mode?

No, 1st it will suck your battery dry. 2nd you don't have H+ coverage everywhere.

2.3.5 Update - 3G Test Results! (Nexus S 4G)

My girlfriend and I both have Nexus S 4G's so I decided to update mine and leave hers at 2.3.4 until I ran some tests. Here is what I concluded after about an hour of testing at home:
Signal strength was improved by around 10db
3G download speeds were 60% faster
3G upload speeds were 40% faster
It's important to note that the Speedtest.net app does not work properly on the Nexus S 4G. To get accurate results, you should use the Speakeasy Speed Test through your phone's web browser, or, tether your computer to your phone and run any speed test from your computer.
I haven't had a chance to test 4G but I am anticipating a big improvement.
Marco
PS. Sorry for the crappy photos taken on my old Evo 4G
It's impossible to rate 3G speed performance increases based off a radio update accurately. Sprints 3G network is such a pile of crap you could get 1mb a second one minute
and this garbage the next.
I tested it a few times over an hour period and got the same results. Beyond that I don't have the time to waste running further tests.
Sorry to hear you get crappy speeds.
did you do any testing on wifi signal strength?
I was getting 2.6 mbps dl at home before update. 60% of that would be crazy. Im on miui atm and idk if im going to update if it blocks tether.
Sent from my Nexus S 4G using XDA Premium App
I didn't test Wifi and unfortunately I just updated her phone to 2.3.5!
Most importantly, how is the signal acquisition? One severe problem I faced is that signal is extremely patchy in areas that should not be patchy at all
Sent from my Nexus S 4G using XDA App
i know it stuffed all sorts of baby unicorns into 4g speeds, previously id average 1.4 down and up.. now i get 2.6 down and 1.7 up
I installed the update via this forum and I have zero signal bars and my airave is 20 feet away if that. My wifi signal indicator jumps around from weak to strong but is mainly weak. I don't know what the deal is, I'm not trying to scare anyone. Its just annoying me.
Is there anyway I can remove this update? I've never done any kind of rooting on my nexus s 4G

OK so I did some playing around with my phone. It seems like everytime I start to make a call I immediately get 2 or 3 bars. Kinda strange.

Do you have the older airave that is only 1x data? If so, it's displaying the 3G bars when not using 1x (either sms or call). You'll never miss a call due to signal if that's the case. It used to be that way for me when I had the older unit (just got the newer 3G airave, and now it's full bars all of the time).

3G signal has become worse for me on the new Radio. I'm now stuck on 1X in my home when I used to be decent 3G.
This sucks.
I'm running rooted 2.3.5 with Matrix 4.0 kernel.
Before update:
WIFI was 4.9 down 4.3 up
4G was 3.6 down 1.5 up
3G was 325 kps down 100 up
After Update:
WIFI is 7.2 down 1.5 up
4G is 4.5 down 1.5 up
3G is 550kps down 100 up
I ran each test a few times.

My 3G speeds before were around 100kbps before the update, and around that now. Sprint is the worst carrier in the whole damn planet. I just check my Evo and it has around 300kbps tops... pathetic. Sprint if you are reading this, you ****ing SUCK
I just got 2.16 megs on my airwave. I used the speakeasy test. Before I could hardly get .8 mbps.

Why is that the case?
2.3.4
3G 300kbps-1000kbps depending on location
4G max 5.5Mbps
Wifi max 6Mbps
2.3.5
3G 500kbps-1200kbps depending on location
4G max 7.5Mbps (!!!)
Wifi max 8Mbps
It seems like to me that one person says it helps and then the next says it sucks so I think I'm just going to leave well enough for now because i have mine on Boost and really don't feel like setting up data and mms again...wouldn't be hard but from the looks of things it really doesn't look like its worth it.

3G Drain on Jelly Bean

Are we likely to see a fix for this? We know there is a problem with 3G drinking battery but how likely are we to see a fix. Solutions like disable 3G aren't viable for a lot of people, so I just wondered what peoples thoughts on this were.
Try changing your modem. You should see a slight improvement in battery life, nothing major but still better than nothing.
Sent from my GT-I9000 using Tapatalk 2
Yeah a modem did help but I still had a big problem. Are we likely to see a fix, I remember this being a problem with ICS which is why I reverted back.
Its not the modem. My phone stock uses the XXKG3 modem, and i have been using that on ICS and now into JB. Jellybean definitely has worse battery concerning 3G / H for some reason. I just barely squeeze a day out of mine.
Yeah, I was struggling to get even a day. I tried almost all of the Jelly Bean ROMs and they all suffered from the same problem. I really wanted to stick with JB, especially C-ROM because it was like a dream to use but on a good day I'd get about 7 or 8 hours maybe? I would always have to plug it in twice a day. Currently trying SauROM which is better but I'm starting to think that the best for battery life is genuinely a stock rom like JVS.

On Jelly Bean?
did you limited your speed to 3g or do you also use hsdpa? if you use hsdpa, give 3g a try i think the battery drain in 3g is a lot lower ... in my opinion if you are not downloading 3g is fast enough to browse or youtube.
for just instant messaging you can give 2g a try
2G isn't really usable on Three mobile.
I don't know how to limit to just 3G. But yes I normally use HSPDA. That said, we should be able to use it without draining our battery
I'm not getting any major battery drain here. I can last a full day on HSDPA and or WiFi.

You CAN limit to just 3G. You have to go to Advanced Settings or Galaxy S Settings (depends on a ROM) and go to HSDPA and put it to UMTS mode only. It'll switch it to 3G and will consume less battery

in my opinion, thats the point, go to settings/advanced/RADIO in your case hsdpa + hsupa should be ticket, simply tick umts an you should notice, the changing radio icon in the status bar (no longer h, but 3g).
your 3g and hspa power consumption depends really strong from the signal strenght and in your phone is connected constantly or changes often. bad reception causes a large waist of battery power.
My guess is you have Google Now / Maps running in background which always uses your data.

On slim 2.9, I found that removing G now, and turning off all location tracking increased battery life. Now I can get a day and about an hour/90mins of screen on time with data/wifi only on when using it. I suppose after more than 2 years of use on the one battery charging every day or more, there's only so much one can expect from a device and battery.
But isn't it recognized that this is a problem? The 3G Bug? Nothing to do with Google Now etc

in my opinion thats not enough, do you mean 24 hours or 16 hours? could be a little more with 90 mins of screen time, but you shouldnt need more.

You cant force it to stay on hspa+ all the time. Same thing applies to a WiFi signal. You can't force a WiFi device to stay connected to WiFi all the time when you're out of range. When you are out of range you will lose the signal and it will try to reconnect.

You can change WCDMA preferred to WCDMA only in the *#*#4636#*#* menu... It doesn't mean signal will magically reach your phone though, it could just be the the N4 isn't as good at picking up a weak-ish 3g signal as your old device. I can't imagine they will have set it up to band-hop unless the signal on wcdma is somewhat marginal.

It switches in response to demand from the device. If your phone is idle or at the very least not using network intensive applications it will ramp the radio down to 3G/Edge. Once your phone detects that you're running applications that demand more network allocation it will adjust appropriately to HSPA+. This is a feature not a bug and if your phone was always using it's HSPA+ capabilities then your battery wouldn't last half a day. I don't even think you can force enable HSPA+ always on anyway, I may be wrong though. If you get it though remember to carry your charger with you.

I might have misunderstood your post a bit, but EDGE does not run on 3G. EDGE works on 2G networks. HS(D/U)PA(+) works on 3G networks. The phone should try to hold on to a 3G (WCDMA, whether that be using HSPA or not) network in preference to a 2G (GSM, whether using EDGE or not) network as long as a strong enough signal is available. Although it was not worded as such, I think the OP was enquiring as to why the phone was dropping to 2G when 3G signal is available, not concerned by whether that 3G signal was HSPA or not and asking if it was possible to switch to 3G only, and I explained how to do that. No modern smartphone automatically drops from 3G/HSPA to 2G/EDGE to save battery, I don't think modern modems draw that much more power when talking to a 3G network. The device will automatically fall back to 'normal' 3G data to save power when the data connection is not in use, but that's a different matter.
