When I had my iPhone I downloaded an application that simply turned off the 3g radio when the phone was asleep. It would switch to 2g for standby and when woken again the 3g would activate. This saved a ton of battery for me during standby. Is there such an app like this for Android? Ive done a little searching but can find nothing other then wifi sleep and 3g scheduling. I'm getting great battery life but would like to squeeze a little more out of my Captivate. Any help is appreciated!

Thats would be cool..... I'm sure it could save battery life.
EDIT: Have you tried Juice defender?
EDIT2: Now that I'm thinking about it..... I would like that as it would change not only data but vouce to 2g(GSM) so if I were to get a voice call while in 2g... it would more than likely continue that way once answered... and IMHO the voice quality on 3g is superior.
When I had the app on my iPhone there were several options, you could set a delay for the 3g radio to turn back on, leave it off completely,etc. When I woke the phone, it instantly (since thats the option I chose) kicked back into 3g from 2g. It was very nice. I had 2g sleep state to save battery but still had 3g for data and calls.
Im sure there is nothing out there like this for android but I figured I would at least check here first before I decided it was pointless to look, we do have a great community of people whom are willing to help, you know.

Well... like I said.... juicedefender has that option.... you could try that out....
I was reading up about Juicedefender on some site earlier. It said it was only a scheduler to turn the 3g on and off at specific times. From the sounds of it theres a few apps out there that do the same thing, I guess ill have to download it and see for myself.
I think there's an app that does what you are looking for called superpower, try googling that or market search it. Hope it works out for you

Juice Defender switches off mobile data, not switches to Edge. It does save battery though.

Thanks guys, this has what I was looking for. I looked over a thread for this app months ago but didnt do to much more with it. It works well but the 30 second delay to switch to 2g isnt to intriguing. Ill play with it more though, its just what I needed. It sucks when you go to shoot a quick text though and have to wait on the data to reactivate though

I guess I was hoping for a little more detail than that.
More powerful how, precisely? Does it boost the signal strength by pushing more power into the phone's signal? Enable different networking standards? Up-clock the circuitry?
One thing it certainly seems to do is absolutely pulverise the battery; I'd like to know what the trade-off is.

Best WiFi performance, silly
Seriously, I switched it on and off. No difference. ~47Mb/s down, ~15Mb/s up.
I've never got more than 15Mb/s up no matter what settings I use.
in my opinion it is just for signal strength...

Well, there is a similar feature for the Note II and what it does is allow you to hang onto poor wifi connections which will drain more battery so the option is disabled by default.. Maybe that's what it is on the HTC One too??
Anybody using this?
I'm having trouble with my push notifications over wifi (being delayed if the screen is off) and I think it has helped me receive them.
Does it drain much more battery?

You probably have Sleep Mode turned on in the Power settings. If you use Power Saver, you might have ticked the Data connection box too.

I've checked them both. Unfortunately not.
And also wifi is on Always On.
That's why I'm trying to find anything else.
3G works fine. I'm not sure if I have the same problem in other wifi networks. One I tried today seemed to work fine.
But I'm checking now whatever option I have.

Seem to be having an issue that I can't take care of that I've tried everything that I know that I believed could be causing the drops. The issue I'm having is any time I turn the screen off while driving my GPS will lose its connection after about 5 minutes. I was also losing data so I figured it was an application causing that issue with that problem I got resolved by removing the battery saving application called battery guru. That was actually shutting my data connection off with my screen off so I got rid of that completely but I still seem to have the problem with my GPS drops. My data stays up just fine but it seems like clockwork every 5 minutes the screens off I'm driving and I get that voice GPS connection lost. All I have to do is click the back button in Google Maps and reload my route and BAM its right back up and going. Now I can leave the screen on and I will not lose the GPS signal whatsoever until I turn the screen off. Have went through all the settings that I know of and of course the only battery saving application that I had installed and I can't seem to find the issue. I also use the search tool and couldn't find anyone else with a problem like mine. Does anyone have any suggestions or have seen this on their device? I'm beginning to think this may be a hardware issue I'm not sure. But if it was a hardware issue you would think I would be losing the connection all the time not with just the screen off which leads me back to a software issue. I'm going to keep freezing apps with titanium to see if I can find another culprit. I just don't have anything else installed that should have anything to do with that. Thanks in advance for any help for insight you may have.

Is called a nexus. Google stock has always had that issue. Unfortunately nexus users spend most of the time locked in a basement and never happen to use gps, therefore they will say their gps works just fine.

My GPS on my Nexus 6 is and always has been amazing. (Thanks for reminding me to compare that when I get the 6P). I use my GPS daily to keep Waze up when I drive to watch for cops, traffic, etc. Even when I know where I'm going I use it and Google play streaming over Bluetooth and my GPS keeps connection even in Manhattan.
I would recommending getting an app called GPS status, it has a few settings to keep GPS active etc, which should solve your problem. However I have no clue what could cause something like that...

Also a problem i had that is probaly related is that i had really low Wi-Fi speeds going from 50+Mbps normally with +-12ms to +-100ms and <1Mbps down.
Someone that also has experienced this or can confirm for me that is a hardware issue as i assume.

no, not hardware or software. the problem most likely is your router. ive seen many that drain an obscene amout of battery, and others that work perfectly. my work wifi drains too much battery.

if it "disappeared", then the problem is your router 100%. sometimes things go fast and smooth, sometimes they dont.
Wifi on these is a little bit glitchy and can go into random power sucking mode sometimes. I've seen it lots of times when EXITING from proximity with a wifi point, even if turning wifi off entirely. The thing just keeps sucking power.
One thing you can do to help it, is in settings/wifi --> Menu/advanced, and UNCHECK the "network notification" button.
However, it doesn't help when you turn the wifi off and if fails to actually power down.
After searching extensively on the whole Nexus 6 signal debacle. I've gotten some observations and studies to share and a couple questions.
I recently obtained a Nexus 6, which I already knew had the ! no data connection problem. (I tried to help the previous owner with the issue before, calls/texts would work, but data wouldn't) They were naturally on T-Mobile, so I assume it was related to the project Fi launch. Googling the issue recently states mostly T-Mobile and Sprint users having the issue, so I decided eh can't pass up a good deal! A like-new Nexus 6 for only $70, who can resist? I figured even if I get the no data issue, I can just turn on airplane mode, use as a mini-tab.
Here's where it gets interesting: I use Cricket (which is AT&T of course), popping the sim in results in good signal, LTE, etc as expected. Randomly (sometimes within 2 minutes) instead of the "!" on service problem, it drops to No Service completely. A reboot and it comes back fine, this wouldn't be too much of an issue except it happens EVERY 2-10 minutes. The only way to get it back is a reboot, airplane mode toggle doesn't help.
Which leads into the second part of the conundrum: Airplane mode doesn't help.
I figured I might just keep it in airplane mode and use as a tablet... The phone said no, Was fully charged before going to bed, by morning 17%. In airplane mode no less, which is of course is abnormal. Looking into it, it seems the phone never went into Deep Sleep, which I immediately delved into the cause. At this time I was running CM13 latest nightly, naturally I went for a fresh stock flash... Same issue. I even stock flashed to 5.0.0 and the same issue... Looks like hardware, but the randomness is the confusing part and you'd think if it was hardware a simple reboot wouldn't fix.
The phone never slept because when it would "No service" on me, I'd get wakelocks for "msm_hsic_host" which would keep the phone awake EVEN IN AIRPLANE MODE, which also in the battery settings showed the red bar for "bad" signal. This happens with AND without a sim, airplane mode or not. I'm currently on Pure Nexus and Franco's kernel to disable hsic wakelocks, and I'm seeing another one for "qcril_pre_client_init" when the issue happens. Which would be the Qualcomm radio interface layer, by the name, I'm assuming android is trying to turn on the radio and keeping the phone awake. This shouldn't happen in airplane mode, I've also tried "Toggle Cell Radio 5.0" to directly turn off the cell radio; Issue remains.
The randomness of when it happens, how it's "resolved" by a simple reboot, and the fact that airplane mode has zero effect on when it happens basically cripples it as a tablet as well, it never sleeps so the battery life is pretty crap (about 18%/hour screen off). After a reboot the thing is great as long as the thing has signal, runs cold, great life, charges fast, sleeps deep. Befuddled that it still does it without a sim card and airplane mode...
My question to the users here: If anyone else has any insight on this, and if anyone knows how to completely disable the cellular interface and literally turn it into a tablet. Is there any rom or such that doesn't try to wake/use the cellular radio and keep the thing awake.
EDIT: Yes, I've run the factory images from google, 5.0.0, 6.0, and 6.0.1 during testing.
The sim card is new, I've already changed it.
Yes the device is actually an XT1103, not a knockoff.
Sorry if any of this information wasn't clear enough.
Further Observations:
During the night I had zero reboots (It's setup to reboot on signal loss, so from here reboot == signal loss), then after taking it off of charge and turning the screen off, then back on after about 5 seconds the signal was lost and it rebooted.
This got me thinking, so on the way to work, I streamed music and had zero problems, not on the charger. After reaching work, I moved some offline music onto my phone and it acted fine as well. The phone never reboots if the screen is kept on as well.
This tells me it's something about how android switches to low-power on the cellular radio. Perhaps the radio cannot wake up properly from the low-voltage sleep state.
tl;dr
When phone is 'active' and not sleeping, problem doesn't arise.
Acts normal with screen off: Streaming music, Regular music, Plugged in.
Acts normal with screen on always.
If doing nothing and phone sleeps: reboots, usually on wake up (i.e. turning screen on to check time)
Likely issue with sleeping/low-power to the cellular radio.
Current bad "solution" play music with phone muted.
However, this doesn't seem to be too bad an impact on battery life, music player has used a total of 1% in the last two hours, screen is top again, where it was android os.
EDIT: Went all day without dropping signal by keeping music playing muted. At 52% after about 12 hours, 3 hours screen on, an hour VOIP call, wifi on the entire time. Not the best solution, but it's livable.
Further testing: I've tried a couple "keep awake" apps that set wakelocks and they do not seem to help, but this might be that they are not designed for marshmallow.
I've also "unoptimized" anything related to phone/cellular in the battery settings to prevent doze from sleeping them, no effect, double the apps directly hit the radio.
first off, first thing that I would do is fastboot flash the latest 6.0.1 factory image(then root it). as the issue sounds like a software problem. if it is, this would fix it. if it still is broken, then I'd root it for sure, then disable the cellular connectivity issue with my root access. without root, you are stuck with airplane mode, only.

I mentioned that I stock flashed... I tried 6.0.1 and even 5.0.0... Also I'm on a custom rom + kernel, so I kiiiinda have root access as well. I don't mean to sound uppity or anything, but did you even read my entire post? If you have a way to completely disable the cellular radio, by all means share. Only other thing I can think of to try tomorrow when I get time is to flash an incompatible baseband, but I can see it causing the same issue with I/O problems.

By saying what you did that doesnt say if you went completely stock with the google images or some of the roms floating around. There is something in the background trying to force the device to connect to cell netowork. I would completely erase the device and make sure to format everything with the flash all bat file. You will ose everything on the device.
Also could be a lose connection in the hardware.

When I said stock, I meant the factory images from google... I've completely wiped the device several times. I'm not new to the entire process... That's why in my original post I stated possible hardware, but curious as to why it does it even in airplane mode when it shouldn't poll the cell radio at all. Further testing seems to say that disabling location access (I generally use battery saver, gps only for navigation), it holds signal longer. Potentially something wrong with how the system requests location.

Are you sure it is a legit device? I have seen some knock offs have this issue.
You know we are all kinda dumb here. Myself included.
Run a logcat and see what is trying to connect.

Already got a new sim, updated info in original post.
Attached a screen with battery info, from testing it's pretty accurate.
After implementing my "solution" for a couple days, it seems to sleep fine now without losing signal. Remember, I have tasker setup to reboot on signal loss so this is informative that it actually sleeps now...
Was the phone ever wet? The signal loss is common on my Nexus, as with my previous, always have missed calls etc, got a voicemail but no missed call notification. However it doesn't really describe the radio issue your describing. I'm almost certain the mother board is malfunctioning. The radio turns to low power mode in doze, but never returns to full power state. Seems to me that it's a communication issue from the motherboard. Neat idea for your "solution".

Phone has never been wet or suffered any trauma such as a drop or high temps. It's an odd little thing.

I have, I think it's a hardware problem where the modem can't wake up from low power state similar to some cpus unable to wake if set too low.
Seemingly a breakthrough
Did a few more things and testing and I seem to have gotten onto something. I've attached screenshots showing just over 3 hours deep sleep and included battery info page. As a recap I couldn't get 10 seconds of deep sleep before tasker would wakeup the phone because it lost signal, then wait 30 seconds before rebooting it to get signal again, unless I was playing music (which kept the phone awake and thus never lost signal). You may notice on the upper left the carrier symbol, I'm on Project Fi and using Signal Spy to show which carrier I'm currently on. After doing my tests today it swaps carriers fine without ever completely dropping the radio and requiring a reboot to regain signal.
I'll do more tests and see how long, if it does to act up. If I seem to have actually found a real solution, I'll post what I did to resolve the issue just incase any other Nexus 6 users are experiencing problems.
Edit: Small note worth mentioning, wifi seems more stable as well. I'm able to keep AndroIRC connected with the screen off whereas I was having issues with it disconnecting randomly. This MAY just be due to something else, but still noting it here.
