Which will give you better battery life: leaving wifi on and using it for calls or leaving wifi off and using cell radio for calls? Thanks.
WiFi. Assuming you are using T-Mobile. WiFi calling also turns off the radio, thus improving life even more.
I will say however that this phone has exceptional talk time off of WiFi. Better than my last iPhone.

For me WiFi calling causes a nasty wakelock from IPService... I stopped using it after that point. I didn't notice any better battery life

Im using FroyoBread 23b, upto now I've been using wifi mainly cause i use the net on my phone alot and the battery doesn't even last a full day, so now im thinking about getting a 3G data plan. SO which uses more battery, wifi or 3g?
3G!!!! Drains battery like hell!
Vote For 3G
Drain battery a lot
3g ,it's very simple......., it's like you will make a normal phone call

Does anyone really see that much of an increase in battery life if you're in a 4g area but force 3g?

I do on the Bionic and the TBolt. I always leave them on 3G. 4G is not needed for anything I do.
It makes a big difference on my Bionic. I don't use 4G unless I'm doing some real surfing. Otherwise I leave it in 3G only mode.
It makes a huge difference in battery life for me, and I live in a good LTE area (Portland, OR). I generally only turn it on 4G if I need the throughput.
Well it was helping but since the update anytime I force cdma only I don't get any data...

also saves me a buttload of battery. Once the update hits my phone, I'll be interested to see if it's still a big battery saver or if the frequent G-Cycle issue was responsible for more of the battery drain than the LTE is, seeing as how that bug has been known to lose me 50% or more of my battery in less than an hour on occasion
I live in Warren Michigan and have awesome service outside and on top floors of buildings or atleast by a Window but on main floors, basements and in buildings reception sucks but there is usually wifi so I switched my mobile network to 2g only and use wifi I get full bars in the basement now when I do this with 2g works just fine for text and making calls wifi does the rest.
Also I did a search to find similar post and didn't get anything but I did it through the phone app.

2G is always a good thing to enable when you're on WiFi. You don't need the fast internet due to WiFi and call quality is sufficient.
And you're saving a lot of battery life.

Yea I just figured it out yesterday And noticing how good my battery is doing today

When my phone tries to connect to 3G it ends up with a very weak signal or no signal at all in parts of my home (also Michigan btw), so I created a Tasker profile to force 2G when I'm at home based on a GPS location, and as I already use Tasker to set volume, etc. when I arrive home this was a seamless fix.
Comparing to my other phone the percentage of battery usage my WiFi seems pretty high. WiFi optimisation is on and the phone is almost always connected to WiFi

it depends i will have to look at my phone when my wife gets home with it.
but if you leave WiFi on all the time even when you leave your routers distance and WiFi is trying to find a wireless network a lot then yes i would expect it to be high because it is contently searching for a network. but if you turn it off when you leave your WiFi network then it maybe kinda high.

The screenshot is from today, it has been on constant home WiFi the whole day. Right now when I checked again 22% of battery is left with WiFi usage accumulating to the same 16%.
On my mom's moto g the WiFi usage is always around 5%. Around the same usage.

Not that it seems too bad to me, but some routers cause issues...also some network setups.
Something to do with the router or network polling your phone way too much.
You'd have to research this possibility tho.....that's all I know about it.
Do you have many wakelocks? Is the phone deep sleeping like a baby?

I think now this had more to do with battery calibration.
My phone has been on for 13 hours today with WiFi using around 12pc with probably an hour searching for an open network ( the phone is almost always connected with WiFi ). So I guess the 12% is fair enough.
I think the network I have been on is set up fine because other android phones don't have the same problem on it
The phone is new so probably its just adjusting.

This phone prefers LTE, I have a very week and unstable LTE at my house so it's constantly cutting in and out. When I'm at home or work I set the phone to CDMA only. Look under mobile data settings. My battery lasts WAY longer and don't have a problem with getting calls. There is zero benefit to being on LTE when you are using wifi. Since LTE at the moment is data only. Only annoying part is switching it back and forth. I wish there was a widget for it or could set tasker to do it automatically.

Yea
LTE is built in to the SoC so when activated, it doesn't turn off. Unlike previous phones who had an external LTE radio, the battery usage is minimal. So overall you are saving battery. and true if you have weak or no LTE signal turning it off will help.

SoC = System on a Chip so LTE, CPU, GPU, CDMA, 3G etc... Are all on 1 chip the Snapdragon 801. Older phones had separate components and used more power but the components could be turned off when not needed. When you are switching to CDMA only you are not just turning off LTE you are changing the core settings on the chip.

I most definitely agree. I have an Airave at home and I have to manually switch to CDMA only while at home for the phone to connect to it. I have a very weak LTE signal so the phone automatically tries to connect to it. Very frustrating. Called airave supprt who said they are aware of the problem and are trying to work on a solution, but for now just manually switch to CDMA only when I get home.
