under phone and mode of operation. If i use 1x, will i get better battery life? and will my reception be just as good as evdo? I don't care how fast my data connection is, because i don't surf the internet, just text and phone. as long as my reception is just as good
You can switch to 1x if you want. The reception should not change, because the phone automatically switches to 1x when you are using the phone. EVDO is only for data. I am not sure about battery life, but I have heard that switching from evdo to 1x uses more battery than keeping it on one setting. In your case, keeping it on 1x won't hurt anything (unless you like looking at the icon).
sounds good, anyone else wanna input? i shouldn't have a problem receiving sms/mms would i? will there be a longer delay on sms/mms as well?
This morning my phone stopped working. Screen went off, couldn't wake it up and couldn't charge it. None of the buttons did anything. I decided to try a soft reset as a last resort and it's working again now. HAs anyone else had this issue, and is it something that occurs a lot? I'm not happy about this

I can't find anything on XDA search to be honest. I tried that link you sent, but I can't find it on that either, any hints as to what keywords I should be using?
I also tried searching by members list, and finding all posts by beards, but I just get this long list, any idea which one he/she is?

try searching the site for standy screen of death.
Its a problem that has afflicted many HTC devices and seems somehow related to the phone moving between 2G and 3G in areas of poor 3G signal

Thanks for that hint, found lots of info on it now. This is going to show how really clueless I am, but apart from 3G being a lot faster I'm not sure what the difference is between 2G and 3G. Also, is the 2G and 3G just related to data usage/transfer, or is it calls as well?
If it's just data transfer then I may as well set it to 3G only as I'm too impatient to wait for the internet etc on 2G. If it responsible for the connection of calls as well I'm going to have to leave it on both as I quite frequently go from3G to 2G areas, and I don't want to keep losing signal for my phone.

GSM (2G) handles all the voice traffic and SMS in UK, plus basic GPRS speed at up to 56Kbps. Where available it also includes (E)dge connections for data up to about 100Kbps (technically can go much higher, but this is the practical limit)
3G and HSDPA (Also termed UMTS and WCDMA) are data only and can allow 330Kbps and up to 7.2Mbps respectively though you'll generally see around 200Kbps and 1-1.5Mbps as usable maxima. These protocols are also used for video calling and MMS media content. However if a device is set for WCDMA only, it can still make/receive voice and SMS services.
If all you do is use email, voice, SMS and basic web page browsing, there is an advantage in constraining the connection to GSM only, as the battery life will improve by up to 25%. For occasional higher volume web browsing it may still be worth staying on GSM, but switching to Auto or WCDMA when needed.
For frequent web use, then it's best to stay on Auto and take the battery hit. Don't select WCDMA only- the 3G service in UK is still patchy and if you go out of a 3G area, you;ll get no signal at all with this selection.
You may also see a few posts on here relating to auto-disconnecting the data signal after a timeout. In general this is not a good idea with current 'connected' devices as it prevents all the 'push' updating of email, Facebook etc. The programs to allow this were originally produced to prevent unwanted data charges when data was expensive, or when roaming. A lot of users are now utilising this in an effort to improve battery life- this is a little futile as the data connection itself uses the normal phone signal service channels and therefore negligible battery power, unless the 3G service is switched off at the same time.

I fI'm reading this right, you need 2G to make and receive calls, therefore if you select 3G only then you can't make and receive calls?

No- if you select 3G only you can make/receive calls and exchange fast data- but only if you are in a 3G coverage area. Out of 3G coverage and there's nothing
GSM only: Voice, SMS, Data wherever theres a signal. Good battery life. Slow data
3G only: Voice, SMS, fast Data, but nothing at all out of 3G coverage. Higher battery drain
Auto: Switches between the 2 above, but favours 3G where available so again, higher battery drain especially in marginal 3G signals where it will continually switch between protocols, potentially using a lot of battery power.

Ok, thanks for clearing this up. If I want to improve battery life, am I best to have it set to 2G, unless I want to use internet/email, and if I want to do that then swap it to 3G for this (assuming I don't want push mail)?
Also, most of the time I'm hooked up to wifi, so I'm assuming in this case I don't need 3G at all?

Even email (polled or push) is fine over 2G unless you are receiving large attachments.
When you are on WiFi, data should take that path so you are correct- 3G won't be needed.
I had been having problems getting 4G at home and just noticed that if I turn off WiFi, 4G pops right up and as soon as I re-enable WiFi (which connects to my home network) 4G disconnects. Has anyone seen this behavior? When you think about it, it makes perfect sense, and since both are enabled to connect when the other one isn't, the flip-flop is automatic. But it surprised me.
its probably because sprints 4G is based on WIFI. or it just cuts off 4G cus you dont need it anymore
I believe it works the same way as WiFi and EVDO works on older phones. When you turn on WiFi it will use that as your data connection instead of EVDO regardless if it is a crappy WiFi connection.

Yeah, it's actually pretty cool, but if you don't know about it, it gets frustrating. I called Sprint customer service and he had me go through the battery out/in routine and go outside and try, etc. So maybe they don't know about it either!
But it makes sense for Sprint, since their data plan is unlimited and they want to avoid network overloading (are you listening AT&T? LOL). The only thing you miss on WiFi are location-based sevices that rely on GPS (navigation, some weather products, etc.).

WiFi and 802.16e aren't all that similar. LOTS of differences between the protocols.
Maybe there's some isolation problems on your device as Sprint is using their 2.5 GHz spectrum holdings for their 4G network.
4g network and 3g network both will shut off when enabling wifi. Why have 2 forms of data going at the same time? Its not gunna use both to double your speeds.
You wont lose any GPS features. Turn on wifi and load up Google Maps, it will find your location exact.
When making calls and sending text it uses 1x so you will still receive everything except for MMS. Maybe they fixed it to where you can receive them even when on wifi with the Evo, not 100% sure.
4g and WiFi are both data only connections. You don't need two data connections simultaneously so it is smart enough to auto disable one to save battery. It would also cause routing problems.
Every phone does this LOL When you switch on Wifi they turn off 2g,3g,4g etc because you can't use 2 data connections at the same time.
I'm curious why you would want 4g and wifi on at the same time?
I thought this was pretty common knowledge (on any Android phone)... And I also thought it was done for battery conservation reasons as much as anything else. WiFi's a simpler point to point connection and from what I understand it sucks less power than 3G or 4G which is constantly checking for additional cell towers in case you've moved, etc.
If you're at home or at work w/a stable WiFi connection you should be able to preserve more battery power by using it, within the settings you can even set it so the phone doesn't revert to 3G when it goes to sleep (the default setting IIRC), otherwise it does this and only jumps back to WiFi when you wake it ('till you're out of range anyway).
I agree with all the comments. And if the Sprint Customer Service guys had said, "Hey, you idiot...it's supposed to do that," then I wouldn't have posted. But the fact that he was as stumped as I was prompted me to post (we all know that Sprint gets all it's info from reading these forums...LOL).
I know this is one app we can try: http://forum.xda-developers.com/showthread.php?t=739530#
But it can't disable switching while do tethering. Can we have this flexible function that we can customize from Settings menu?
I noticed our SGSIII can switch off and on WIFI when the screen on and off. It's good if our SGSIII already have the function what I want and it good enough to now what we do when the screen off, it will not switch to 2G when we do tethering and downloading.
GS2 / note / s3
If network idle, it 's will auto down to 3G umts or HPDPA to keep the battery life.
1 hour with auto sync-> 1-1.5%
2g can save battery ?i think not so much with network online.

As I remember correctly AOKP has this feature under their powersaving settings. From what I can tell from my I9000 I always lost mobile data connection entirely when turning screen back on... took 10-60 seconds to get an active 3G data connection again. That kinda really pissed me off cuz it is very likely you need your internet connection when pulling the phone out and turning the screen on ... and in that case having no connection really sucks.
So I never used that option (besides using manual 2G limitation if wanted).

Thanks for the info. My home town just have 2G connection. I think it's better if it directly connected via 2G, rather than the phone continuously searching 3G line.
I love my new Galaxy S III, but once again I have no way to force HSPA+ only. I need this option while my phone sits in my desk all day. If I can turn LTE off then I can save battery life and still get calls/texts/emails.
STOP IT AT&T, JUST STOP IT!!! Your really starting to really aggravate your customers by not allowing them to select their preferred network.
I want the network mode option in mobile networks:
GSM/HSPA/LTE (Auto)
GSM/HSPA (Auto)
HSPA (only)
GSM (only)
STOP taking this off all your phones. Every other GSM carrier in the world allows this except you!!!
I hope ALL developers add this toggle in all the upcoming roms.
Your best bet until this is added/fixed, is to turn on wi-fi mode and turn off the mobile data connection.
That way you still can make calls, and have the wifi as your data, and if its off it wont use as much power as HSPA/LTE.

I think you kind of missed the point...
Let's say your at work all day and you don't use your phone much? Let's say your phone gets 1 bar of LTE and 4 of HSPA+. The signal constantly fluctuates ultimately leading to a dead battery much faster.
Wouldn't it be great to just turn LTE off? That way my phone gets a better signal and uses less battery life. Not to mention, I can still receive calls, texts, and e-mails, whereas airplane mode disables everything.
Wi-Fi isn't available everywhere.
PS: AT&T ain't adding ****, they released their first LTE device in November of 2011 and it also lacked this option.
I think you missed the point as well
The reason for turning on wi-fi is to direct the data connection to something other than the chip used for HSPA/LTE. I'm not looking to use the wi-fi connection as an alternative data source. I'm using it to prevent as much battery drain as possible whenever I am not using the phone.
It essentially IS turning off LTE, but it also is turning off your data, and if you don't have wi-fi then you wont have a data connection, but if you do then you will.
Airplane mode is just taking it a step further and blocking calls as well.
So there's no way to turn off LTE? Even via a 4g/3g toggle from the app store?

Nope, that's not how it worked on the HTC One X... even dialer codes would just reset on exiting. LTE stays on for some stupid reason with ATT.
A bet a toggle with root requirements will come out later./

Then it would be best to turn off the Wi-fi and the Mobile Data connection, the only reason I have the Wi-fi on is if I'm in an area that has it (home, work, at&t hotspot) otherwise it is automatically turned off (I think?).
And I agree completely, I would love that feature, but until that time we have to make due with what we have, this is my solution, it isn't perfect but it works for me.

Yes, but like I said turning off mobile data completely turns off the data connection, whereas with this toggle we can change it to EDGE or HSPA+ only, still having a data connection.
I agree I like turning on edge only when I'm at work and home

i guess technically it could since it turns off everything (Except calls) and turns it all back on every 15 minutes to check if anything was received on Att servers.
But if hes waiting for an important text or something, it would come delayed until juice defender decided to retrieve it.
not a bad idea though.

I believe it just turns off 3g and 4g on verizon. My calls and texts are instant. Also, if you buy the app you can change frequency. Mine syncs every hour or two. It may be different with att since verizon handles their 4g in kind of a silly way.
