I have been playing with the native internet calling features on my VZW Nexus to use when I switch to GSM. Everyone ive seen has said not to have 'recieve calls' selected because of battery drain. the weird thing is that I dont have any noticable change when I am using the feature. Is there any documented proof of how much drain it causes?

Does battery usage increase significantly while the APN is enabled?
I tested it even without auto-sync enabled and it seems to get through about 6-7% per hour (with the screen off!)
With APN turned off it barely uses 1% per hour!
I'm using the XWJG5 release with doc's deodexed rom installed and the sd card lag fix.
Anyone else experience this?
that is normal, even when using the HTC Athena or any other phones that uses EDGE, 2G, 3G, etc
next time please post these sort of questions / comments to the "Galaxy S I9000 General" forum instead of Development.
I searched and was not able to find anything related.
Has anyone thought about this?
I enjoy having a WiFi sleep policy when its idle. Maybe something like this exist for Mobile Networks?
I'm pretty sure something like this already exists. Check Settings>wireless&networks>mobile networks>enable always on mobile data. My experience is that if you disable this your phone will go go idle on mobile data about 10 minutes after you turn off the screen. The problem is that this will delay your email and data synced items by about 30min to an hour depending on your settings.
I experimented with it and didn't really notice a huge benefit to the battery life. But I also constantly pull my phone out to play with it (which re-activates on the network, i think).
Hello everybody, I was wondering if anyone know of any ROM that allows to switch from 2g to 3g (or viceversa) automatically to some apps, like juicedefender, or extended controls. I think Cyanogenmod allows it, but I heard it doesn't provide a good energy administration.
And in the other hand, as I talked about energy administration, what ROM do you think works better for battery in DHD?
Thank you guys!
after all this time... nobody?
You can't toggle 2g/3g for some apps only, it's kinda global, for the entire system...
I think he means that it triggers the switch on some apps.

the switch between 2G and 3G has not direct relation to the type or form of application, it can only be manually selected by the user, this is the fact that in areas where 3G is unavaliable or weak, the phone may switch to 2G to ensure a stronger, more stable signal. keep in mind, mobile data (2G or 3G) also consume a relative part of your battery
I know that there is relative difference between 2G and 3G power consumption but the type of ROM and Kernel is a major part in determining the battery life. The current set up I use gives me approximately drain of 15% for 6 hours with approximately 30 txt and 10 minutes of call time all through 3G signals with the WIFI switched on. with a battery life like that, switching to 2G is relatively pointless. doubt it would save substantially.
I See my wifi has used 30% of my battery but ive been on 3G all day, does it drain the battery searching for networks?
It does use some power when searching for networks. There is probably an APP or settings that you can change to set the Freq of checks maybe. Or you can just turn of the Wifi radio when you know your not going to use it.

Yes it uses a lot of power if its regularly searching for networks. Especially if you're moving around and seeing dozens of WiFi spots. Just turn off WiFi when not in use, simple as that.
A lot of custom ROMs have less aggressive Wifi seeking intervals. You can usually set it manually with ease too. Lots of apps out there if you don't want to do it manually.
All that was said is true, but still I find that 30% usage for Wifi just for searching nearby networks is a little too much...
Although I haven't got anything to compare with, I always turn wifi off if I'm not using it during long periods.
Regards
I turn wifi off when it is not needed and battery life goes from one to two days.

I've been using Tasker to turn wifi on at home/work and off when I'm elsewhere. It's using cell towers to determine location, so hopefully it won't impact the battery much.
I leave wifi on 24/7, today it has used 2% of the 60% battery i've used.
I travel through london so I assume it is constantly finding new wifi signals.

Y5 Battery Saver .. on the market, free. Turns on/off Wifi based on known networks and cells in the area of the AP.

I leave wifi on all the time as well, and I also only have used 2% of the 70-80% battery I used up already.
Try going into wifi settings, then advanced wifi settings, then turn off the new wifi network available notification option.
This increased my battery life slightly.

Y5 - Battery Saver helps out tremendously! I barely ever use more than 2% when home all day...although that may be a bug but I started a thread for that already.

That 30% displayed can be deceptive since it's based on the amount of battery discharged and not entire battery capacity.
Well wifi, when on is looking to connect to known networks. If the signal is weak it will disconnect and connect to another network near by if there is that has better signal. This process does use some battery. The biggest drain will occur when you are actively using wifi, that is when you download or upload. So the best way to save battery, is to close wifi when not needed. If however you want wifi you can set it to never sleep. This way even if the screen goes off wifi will be connected and your device wont use the 3G which is way more power hungry.
I think I remember an app it was called Tasker. Where it ( I believe ) used your location to set certain settings. True? If thats the case, couldn't I set it to change my internet to 3g when I get to work and wifi turn on when I get home? If it does use your location wouldnt that use more battery? Or is a simple toggle the best? Id like an automatic option if possible.
Battery usage depends on how it detects your location. GPS would me the most accurate and use the midst battery. Network is only accurate to a couple miles/km, but uses less battery. I use what cell tower I am connected to wish is more accurate than location, used less battery but can be less reliable as there can often be several towers you connect to, took me a few days to set them all. Also, if towers get upgraded, that can throw things off until you update your settings. I also had problems with wifi calling as that disconnects you from towers all together.
But yes, tasker is awesome.
Tasker and Locale do this, and much much more. Looking to just change networks, other apps like Juice Defender will do it too.
They of course will drain some battery because they need to use GPS and be running in the background to properly work. Of course you could choose to use network location but you won't get as good of performance as far as specific location services.
