So there are a few related threads but specifically what I am looking for in this one is how to hard set the phone to "stay" on 3G.
While at some venues in town the phone constantly, every minute or two, switches between 3G and 4G which is drains the battery while I am there. Within a few hours the battery will be dead from full charge.
So looking for ways to prevent 4G from activating especially when I am at these locations. There used to be a setting in the G1 that forced it to stay in 2G. So anything similar or disabling certain frequencies that might help.

I work in an office which is a level below ground in central Sydney so most of my work day I am out of reception.
Now I do venture into reception areas so every now and then so don't want to turn aeroplane mode on and off all the time.... So please don't suggest this.
With my previous phone (i8000) I didn't have such a drain on battery when out of reception all day from what I remember. I used to get really long standby times but I didn't use the screen anywhere near as much.
Now I know the phone will use more power in low reception areas because it needs to turn the sensitivity up to get clear signal. But the i9100 seems to drain much more than all my other phones I have used.
I am on stock I3 firmware with CT Root kernel. I have a high level of 44% Cell Standby with only being on for 6 hours (and out of reception for 3 of them) even though I have used the screen for 1 hour and that only shows 37% of usage. I don't remember it being this bad on H3 but to be honest I didn't really check for comparison of usage.
Is this normal? My old O2 phone on win mo used to go into a state of sleep for searching for reception when at work because it used to take a few minutes sometimes, after I got into reception zone, to realise I had reception. The i9100 seems to get it straight away which makes me think is it polling all the time I am at work and draining the battery more because it tries so hard?
Hope I made this clear.
So it appears like from research this high drain is fairly common on android devices when in no reception areas. I could understand why it would happen in low reception areas where the phone uses more power to pick up a weak signal. But why would the phone continually do this in a NO recpetion area. I thought samsung would have made the phone relaise it has no reception and only try every 5 minutes or so...
I never noticed this on my i8000 or any of my win mo phones before it. I assume they realsied there was no reception and stopped polling at full strength the whole time I was at work. This would have been indicated by the slight delay of leaving my bilding before getting messages sometimes where now its instant. But without the battery usage stats I can't compare.
I have tried to find an app that automatically puts the phone into aeroplane mode when NO signal for 30 minutes or something. And keep s turning aeroplane off every 5 or 10 minutes or so. But I have yet to find anything.
I realise there are programs that will use GPS and do it automatically but this is not ideal. I only want it to happen when I have no reception.
Any ideas of ways to fix this without me manually putting my phone into aeroplane mode when I'm in my office and remembering to take it back out when I know I should have reception? I don't want to use location based because this doesn't work when I go up one level.
Just bumping my ancient thread.
After an app that will recognised NO reception for long periods and automatically put flights mode on. Then turn flight mode off briefly every 5 minutes or so to check if reception is back.
In my office I have no reception but if I go up two levels I do. So time based automation does not suit nor does location based unless it knows what level I am on.
See above for the long story

I've considered switching to VZW from T-Mo. One of my concerns is battery life with 4G. Can 4G be turned off with something like Juice Defender? Do you really need 4G while your phone is sleeping, pushing e-mails?
You can change it to 3g only in the network settings.
The only time I need 4g is when im showing off.
Yes, there is usually a switch between forcing LTE mode, deactivating LTE, or allowing your phone to choose between 4G and 3G based on signal strength.
Another thing to remember is when you're at home, you can use your wifi connection.
I have had both the HTC Thunderbolt and Samsung Droid Charge, so from my experience keeping 4G on is craaaaazy fast battery drain.

Yes, but can I do it systematically? Also, can the phone pick up 4G while you are on a call to instantiate voice & data simultaneously? I would use the data speeds regularly, but don't need them while the screen is off.
BUMP......
It probably can be done with smart actions? I haven't taken a good look at it yet, but seems promising.

there are 4g toggle apps in the market making swapping service very easy.. 2 nights ago i went about 10 hours w/ 4G on with moderate use before getting a 20% battery warning.. last night i tried 4g off, went to work, forgot to plug my phone in at night and woke up to 50% battery, unplugged for 20 hours (both nights i had a full charge before leaving for work).. it's a pretty drastic difference, 4G is blazing fast tho, i'd love to be able to keep it on 24/7..
Heya all.
I'd like to know is there some android application that can control my 2G/3G settings based on a rule (something like AutomateIt, which does not do that) so that it stops my phone from trying to connect to 3G network when signal is low or lost?
Let me explain - I go twice a week to a gym which is actually in the basement of a building, and my carrier's network is very weak there, mostly no signal at all.
During those 2hrs period I've noticed that my battery drainage is larger than when I'm in the reach of the network.
Since I know that cell phones tries to log-on to the network using maximum power, and that 3G uses more juice than 2G, I concluded that my phone is trying to reconnect to 3G network when it looses signal instead of doing nothing.
Now, I don't exactly know how phones in general behave when they loose signal alltogether (I think they go from 3G down to 2G and then should go into some passive, listening-only mode, waiting for the beacon from the cell tower), but I guess that in such cases it would be better for me to force the phone to go to 2G (and keep reconnecting/listening on 2G) and later on, when it detects 3G, switch back to it.
Unfortunatelly, AutomateIt does not have radio control and I can't use it like I do at night to turn off sync and data and turn it on in the morning.
Also it does not have a rule related to network signal strength/type/whatever.
I can't use some timer app that would simply turn on/off airplane mode during that period, because I might not go to the gym sometimes, or I might simply be late or leave the gym later, so I'd still have larger battery drainage, even for a short period of time.
Many words, but I hope everybody understands my problem.
Cheers.
OK is it possible that nobody knows the answer to this?
I know that 2g/3g autoswitching should do it's job but watching my power drainage I get the feeling that phone keeps trying to force 3g and that eats the battery.

Not sure if this has been posted before, so I apologize if this is a repeated post.
I had been losing 4G service randomly over the past few days. 1X and 3G would be the the only service I would receive in places where I previously been receiving strong 4G.
The service would also return intermittently.
I have an extended battery and a standard battery, which I have been cycling through full charge / discharge.
I have Fast Boot turned off in power settings.
What I have found is that my cell network settings reset or change on their own, each time I shut down and/or do a battery pull.
Normally I have Network Mode set to LTE/CDMA and Enable Always-on mobile data is checked.
What I think is happening is that when I bring the battery down to nearly 5%, my power-saver settings shift from Performance to Normal. My LTE is then shut off and when I replace the battery with a charged one, the power saver settings remain in Normal, with LTE shut off.
I'll spend some time verifying and I guess the answer is really to not condition my batteries by discharging past 10%.
I may also be allowing this to happen by responding improperly to the low battery notification.
Hope this helps anyone experiencing loss of 4G...

Verizon has had some disruptions this week, nothing wrong with your phone.

Battery saver mode shuts off auto sync, 4G, and always on mobile data. You need to set battery in settings back to performance instead of normal or economy.

I actually checked that in the 4G outage thread, but two respondents from my area (NY/NJ) said there were no outages. But I think that's why it was so hard for me to troubleshoot the other reasons for my 4G loss.

There seem to be some quirks on the phone. I will see 1x to 3G to LTE (in that progression) if I have been in an underground parking garage, or maybe a weak WiFi that comes in and out. For the most part, when I see 1x or 3G, I assume verizon is having some issues. 99% of the time it just comes back. 1% or less (probably less), I toggle mobile networks.
Hi,
my carrier Three UK only has a 3g network hence so switching off 3g is no possible for me. When at home I always connect to my wifi automatically using a tasker profile and my battery can last over the whole weekend with moderate use. However, when I am out or at work without access to wifi my battery can drain more than 60% in a matter of 10 hours, although I use a Tasker profile which only turns on autosync every hour for just 2 minutes. I could turn of background data completely, but to me that would defeat the point of having apps like gtalk, skype etcv on your phone.
What's your experience of battery life on wifi and 3g?
I have my atrix on Orange UK. I get round about the same battery if i have my phone on 3G and most of the time it says H. I can get much more time on wifi but not the whole weekend because i use it more heavily i guess. Although it also depends what rom your using…stock roms are pretty pathetic on battery life due to blur. I was using joker's cm9 and even though i had 3g on whole day my battery lasted 2 days.

For me, much better battery life on wifi (40-48 hours in weekend on wifi vs 30-36 hours in work days on edge/3G).
When your device is connected to Wi-Fi, then it will consume less battery as it needs less 'juice' to receive data from a Wi-Fi network than a cellular network.
However, if you are on 3G, but have Wi-Fi enabled, then your phone will consume more battery than with Wi-Fi disabled as the phone frequently scans for Wi-Fi networks. The scan time is configurable and stock ROM and CM7 scan every 30 seconds, whereas Neutrino ROM scans every 2 minutes. This means that Neutrino will have slightly better battery with Wi-Fi always enabled as it scans 4x less than normal.
To configure the scan time, you'll have to edit the build.prop.
Regarding your Tasker profile, it's the same thing. Tasker needs to 'detect' when Wi-Fi is on/off and scan for networks in accordance to your personal settings. Therefore it'll still consume battery while it scans and detects.
This brings in the issue of whether it'll be better to use Tasker profiles, or to keep Wi-Fi always enabled and the result will differ for every person depending on the Wi-Fi scan time, or the complications of the Tasker profile.
But putting complications aside, Wi-Fi consumes less battery than 3G, but only when connected.
