Hello everyone.
I've just update to CM10 from CM7.2, and I really like it. Kudos to Epsilon and Quark for their work.
In CM7.x, there was the possibility to link 3G and Data usage, meaning that when I activated 3G, data would be automatically activated, and when I switched back to 2G, data would be desactivated. It was really convenient for me, allowing for longer battery cycles, and stricter data usage.
I can't find this feature on CM10. Do you know if there is a way to achieve it? Maybe via an app?
thanks for your answers.
Use Llama. It can control both 2G/3( and mobile data on/off. Just set up one event to switch to 3G and turn on data, then another to switch to 2G and switch off data.
I've got my Llama doing allot of data management stuff. The beauty of it is that it has location based triggers that don't use any battery up looking for location services. It uses the cell ID of the tower you are connected to (and/or available wifi/Bluetooth if you want) to determine where you are.

Ive seen some apps that switch from 2g to 3g and vice versa in different situations such as when the phone goes to standby or when certain applications are opened. However on my g1 (i know they are different hardware and os) switching from 2g to 3g and vice Versa used more energy than simply leaving it on one of them. Is this the case on the hd2?
yes it is still the case.
I live on the edge of my 3g area, ranging from 3 bar 2g up to 3 bar 3g, and normally keep my phone on 2g only, but if I forget I lose around an extra 25% battery thought the day, say... 12 hours.

thanks, i guess ill just have to stick to 2g.
i live in an area with great t-mobile coverage (both 2g and 3g) and i noticed 3g uses a lot more power than 2g, so what i do is i keep it on 2g most of the time and turn on 3g when i need it the most (gps, quick google searches etc) battery lasts a lot longer than leaving it on 3g all day.
guys.. this pertains to your discussion. there is an app developed called wmlonglife
which keeps your phone in 2g mode until you launch an app that requires 3g then it auto switches it on then off when your done. it does other stuff too like turn off 3g when your screen is off... or turn off 3g when ur using wifi... its perfect. i got at LEAST +25 % longer time between charges on ym HD2 because of this app.

so there. hope that helps you out some

About
WMLongLife is an automatic 2G/3G band-switching solution. It will keep your device in 2G when you do not need to use 3G, and will switch to 3G automatically when you do need it. For most users, having your device in 2G uses much less battery, and thus your phone lasts longer on a single charge. 2G also usually generates less radiation than 3G, so it will likely be better for your gonads (if you have them) as well (see this thread for a discussion about that) - think of your hypothetical future children!
Main features
* 2G/3G (auto)/3G (only) automatic band switching based on:
- Running programs and their needs
- Availability of Wi-Fi
- Availability of USB
- Roaming [note: most roaming options have been removed, use the RoamFreely (marketplace) tool instead]
* Idle data connections disconnect based on running programs (note that unlike the registry tweak this does not break simultaneous voice/data)
* Manual band switching
* Automatically disable data when roaming (including AGPS)
* Pauses applications while switching bands (so you don't get networking errors)
* Several predefined applications supported
* Support for HTC/MSM72xx GSM devices (GSM/EDGE vs UMTS/HSDPA)
* Support for HTC/MSM75xx CDMA devices (1xRTT vs EV-DO)
* Support for various Samsung GSM devices (GSM/EDGE vs UMTS/HSDPA)
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).
Is there any way that you can turn off the 3g to save battery because on other android phones like the g1 it allows to turn off the 3g and seeing this is the first 4g phone EVEERRRRRR!!! i think it should have some way to turn off the 3g capability to save battery,,any suggestions
You are able to turn off 3G completely by going to Apps>Settings>Wireless Networks>Uncheck Mobile Network
yea but there gotta b a way without disabling the internet
No way because voice and data are 2 separate signals and cant be used simultaneously. The 3g is the thing that kills the battery because it is always looking for a better signal. If you turn that off, voice will stay at "1x", thus saving battery and you can still receive sms and mms

I have an Evo running CM7 on the SRDO plan, my phone is very rarely used to make or receive calls. I would like to be able to turn the cell radio off while keeping the mobile data active, if this is possible. Please let me know if there is a way to do this, preferably with a toggle widget but I'll consider a more complex solution if need be. Thanks in advance.

You can turn mobile data off and have the phone on but I've never heard of a way to turn the phone off and use mobile data.
Unless its pure wifi and which you CAN use in airplane mode.
..
You can change how often it polls the towers but data and voice are done with the same radio. It just switches over to 1x instead of 3g to talk.
Since I got my Defy+ more than a year ago, I could never get my current location on apps like Google Maps, CityMaps2Go, MapsWithMe etc, with mobile network signal only (i.e. wifi OFF, GPS OFF, mobile data OFF). It has been the same with stock rom, CM7 or CM10 by Quarx
Is it supposed to work with purely mobile network signal?
I travel a lot & I don't use mobile data when overseas. I need the location function when I am on the road.
