any one knows how can i disable 3.5G/3.7G/ HSDPA /HSUPA/ HSPA data connection , i want only Normal 3G data connectoin
because i already have poor internet connection due to network operator policie , and my subsecribed bandwidth , so my phone just, use HSPA but no speed is needed , so no battery drain is needed .
so i can save battery when i am surfing the internet

rooted + supercharged
You won't save any battery by that.
And I seriously doubt you wish to use 3G only. 3G is very slow, compared to HSPA speeds. I do not think any of the operators actually limits the speed to 3G speed (384 Kbit/s, for comparison, HSDPA is 14 Mbit/s).
i know that

i know that ,but, my network operator already have very poor connection , no more than 512Kbit/s , i use it only for chat on mobile data ,

btw, i have a question...: does ''use only 2g networks'' saves some battery?? b'cuz i activate that if iam over my limt, bcuz my provider reduce my surfspeed to 64kbits/s and i thought, that didnt affect my surf speed and saves battery?? right or not?
thanks in advance
Using 2G does save battery in some cases. In city areas, it is not noticeable. From my own experience, I can say, that if I use 2G, the signal is strong all the time (operator's 2G antenna radius is larger than 3G), however with 3G, it goes up and down at my home. If signal is strong all the time, phone has to use less battery to keep connected. If signal is weak, phone needs to use more battery to keep the connection.
Long story short - Yes, it can save battery, however in city conditions, it is hard to notice.

yeah you are right.. 2G network consumes very less battery than 3G

Hey, I have an USA T-Mobile Vibrant.
It is rooted and running the Vibrant edition of Darky's 9.3 Final ROM.
I am also using the latest overstock kernal and the honeycomb 2.0 theme from the I9000 forums.
Enough background info. This isn't really a problem as much as my curiosity.
My phone almost constantly is switching back and forth between 3G (UMTS) and H (HSDPA) on my data connection.
It doesn't seem to affect battery life or service too much (though H might be faster), so I'm not worried; but does anyone know what the deal is with this?
Thanks ahead of time!!!
Sent from my Vibrant using XDA App
Mine has been doing this lately as well. It's only been happening since I installed my current ROM (Trigger 2.7).
Noticed this just now as well...might have something to do with the mods to show H or 3G.
I wonder if it has anything to do with signal strength. I know that shouldn't make a difference but I can't think of any other reason.

I would agree, but I went to my settings/ phone info/ signal page and the reason it was changing was because it was physically switching between UMTS and HSDPA.
Why? I have no idea.
I do live in a T-Mobile 4G enabled area, though I am not on their so called "4G plan".
I did notice that it did not have this switching problem on Bionix Frost-u2.
So, if anyone has some insight, please help us all understand

I was just watching my signal strength change and it doesn't seemed tied to the change from 3G to H.
For example, it would be around 67dBm and be on UMTS. Raise to up to around 75dBm and be on UMTS. Then it would switch to HSDPA and still be at 75dBm or sometimes lower down to 69-72dBm and still be on HSDPA.
So with that type of cross-over stats, I would be skeptical of that solution.
HSDPA is a temporary data link. If it was on continously the phone would have very poor battery life.
When network server has a data packet for your phone it 'pages' up your HSDPA capability. Your phone can also request HSPA to initiate a data transmission.
The HSPA paging process is similar to receiving and initiating a voice call.
If no more packets have qued at their server or received from your phone after some period of time it will revert to normal 3G battery saver cycling. It has to be re-paged up to reinitiate HSPA data link. The wake up HSPA function does add some initial delay.
So is there a way to force it to stay on HSPA while tethered, for example? (Or always)
Does anyone else on Tmo/Orange Uk have issues with 3G speeds? Mine are much slower than on the SGS and I can't figure out why.... I'm starting to worry if my phone has a fault ....
anyone had issues?
thanks!!
Dont think it's your phones fault. I get up to 4mbps everytime i take a test, and i got only 2mbps with my desire so, yeh this phone rocks.

just 3G speeds? or with 'H' aswell? download 'speedtest' from android market(free), if your download speed hovers around 356-357kbs, then I would say your download speed is capped.I'm with t-mobile, and mine was. I had to phone and get through to their techy dept and get them to enable 'Hspda'

whats the difference between H and 3g? coz mine goes from h to 3g and then back to h, that didnt happen on my desire. i always thought H was the same as 3g :S

http://blog.ruggedandmobile.com/2010/01/26/a-guide-on-the-difference-between-gprs-edge-3g-and-hsdpa/
G - this stands for GPRS, and is the slowest data transfer method (approx 32 - 48 Kbps)
3G - This is the next level available on T-Mobile, and is around 10 times faster (384 Kbps)
H - stands for High Speed Downlink Packet Access, and is essentially 3.5G. In theory, TM's network
can transfer at 7.2Mbps, but real world tests tend to average out at around 2 Mbps, still significantly
faster than 3G
There is also HSDPA+(H+) which is even faster.
Hope this helps explain

Nice details, thanks bud! i guess my desire wasn't capable of doing 4mbps, it only got upto 2 while sgs2 gets upto 4mbps which is awesome
Hi All,
I have the Speedtest.net app on my SGSII and have run some speed tests and am getting some results that I find weird.
Yesterday I tested my network speed from my home (small basement suite apartment if that matters) and the results were as follows...
Network HSPA Download -0kbps, Upload -0kbps, Ping -1ms at 8:12PM
Network HSPA Download 247kbps, Upload 15kbps, Ping 1172ms at 8:14PM
Network WiFi Download 11401kbps, Upload 505kbps, Ping 47ms at 8:26PM
Today
Network UMTS Download 2269kbps, Upload 664kbps, Ping 185ms at 10:07am
I know the WiFi ones will be different but can anyone tell me why my HSPA ones from yesterday are SO LOW and if my UMTS (3G) one from today is atleast in the normal range?
I am confused...
Thanks,
One test isn't enough. Maybe the network/cell tower was saturated or had a problem, preventing full speed in your HSPA test.
The 0/0/-1 are Speedtest's bug.

Thank You for the info. Can you explain to me... Is UMTS 3G and HSPA is 3G+? Is that correct?
Today at work I ran a couple more tests and my UMTS Results were fluctuating as well... (I diddnt have any tests that came back HSPA today so far) Anywhere between 863kbps download to 1390kbps download and 301kbps upload to 748kbps upload... Are these weird as well? How can I get a true test of my 3G and HSPA speeds?
they are just slower speeds, the network seems to be under heavy capacity in your area. the only way to get a better idea is to test in the middle of the night, at 1 am, when the network is nearly empty and wide open.

Thank You as well for your response. Can you tell me... IF my device was folr some reason running in 2G or "Edge" mode it would show that as the "Network Type" in the test like it says UMTS or HSPA? Is that correct?
Yes if your phone switches to edge you will see an E at the top of the screen and the setting menu will say edge. You were definitely on HSDPA though, just a slow network, cause edge is limited to 236 kbps. Your speeds were higher than that except for the one that goofed completely.
Does any user having issue with the network signal?
My phone is working fine but every time when there is data flowing, the network connection cycles from 3G to HSPA to HSPA+, then go back to HSPA, but the speed never be interrupted. Is this a design for the phone or this is actually defect? Flashing modem will solve this issue or not? Please advise.

The same thing happen with my phone as well.
I think it shifts between 3G to HSPA to HSPA+ to save power when data is not being used at that moment.
It actually means your connection quality a bit like signal strength, which is perfectly normal under different environment.
Gives you more bandwidth while quality is high and drops when low.

Thank you above, all thanks already. this comforts me now.
I'm on MIUI dev. At my place the Jio service is pretty poor. I get the max. speed of 100KBps throughout the day, and only during the nights I am able to reach upto 3or4MBps.
But, what I've seen is that sometimes in between, my cell connects to some other Cell Tower (Jio's only). I can tell you this because the network strength is always full at my place but when it gets switched to the other Tower's signal, the strength is around 40-50%. And, suddenly the speed gets boosted upto 2MBps from 100KBps, for the brief 10secs. Then again the network strength goes full and the speed comes back to its normal.
So, what I think, is that there's another cell tower which is farther then this one but has less no. of users and hence better speeds.
So, is there anyway that I can switch to that network permanently. I've read about setting the phone's modem to a particular freq..
So, guys tell me what I can do.
TL; DR How can I use the other cell tower of my network which has better internet speeds but has weaker network strength.

Tested it. Works as it says, but the speed is still same. Hell, Im getting speed around 100kbps+ on Band 5, while on Band40 the speed is around 60kbps. Although the network strength is full in both bands.
Anyway, thanks for your reply. It must be problem with Jio services only.
