Does having WiFi calling enabled drain the battery? I've enabled it and it seems like a good feature I'm just curious in people's experience what effect it has if any to battery life

i have noticed keeping wifi router setting to "wireless mode g" helps in improving battery life of s4 ... as when i do "wireless mode n" it gives me less battery life... have anyone else noticed this??
I noticed that my battery is draining faster when I'm at work than when I'm at home. Both have wi-fi.
Here's a screenshot on which you can clearly see the moment I get home. Is it possible my work-router is sucking the life out of my battery?

You need to look at you battery stats on the previous screen and see if anything stands out there, mine are like this from this morning and I have a 48 mile drive to and from work, no WiFi use at work only 4G but I tend to forget to turn WiFi off so its on a lot but not connected, I would guess something else is draining the battery though, if you don'e see anything in the battery usage just try a day with your WiFi off whilst at work.
Turning off wi-fi at work saves battery too (although not as much as using wi-fi at home).
If so, have you noticed any decrease in battery life? Saw a couple of articles highlighting this feature back in May, but there hasn't been any follow up to the feature's effect on battery life. Thanks in advance.
I have it enabled and can't say that I see any remarkable decrease in battery at all. I'm not really sure of the benefit if any either though.

Supposedly, the phone doesn't have to re-establish a cellular data connection, so you're less likely to have hangups when switching from wifi to cellular. I also have "aggressive wi-fi to cellular handover" enabled so the phone doesn't hold onto my wi-fi connection when it gets weak.
Did anyone test the battery life ? how is the battery life once you enable this option?
Hey guys, I am having some problems with my battery on cm13, it's good when I am using the phone but standby time is just horrible, in 15mins i lose about 3-4%. Does anyone else have this problem,and do you know how to fix it?
First try and update to the newest cm13 nightly
Also look at battery in setting menu and see what uses your battery the most
Also turning off features such as wifi Bluetooth nfc and data connection and turn off wifi and Bluetooth scanning and location except when you need them
If you have a weak 4g cellular signal you may
Need to switch to 3g in network settings some custom kernels have atrocious battery life also sorry to throw a book at you but the all that apply to you
Turn off sync also helps a lot
Turn on efficiency or power saving in battery settings also helps
Then turn on simulate color space monochrome in developer options
Turn off ok Google also
Also turn off usb debugging when your not using it

Can someone confirm if this issue exists on their device?
I live in an area with no cell service so I put my device in airplane mode and use WiFi Calling. This worked great for my OnePlus 5T. Now with my 6T I get very heavy battery drain when I do the same. Somewhere between 2 and 4 percent an hour. If I have good cell reception and airplane mode off I don't get any standby drain, like it should be. I have attached a screenshot of the drain while my phone was in standby. The red boxes highlight when it was in airplane mode with WiFi Calling.
I would like to figure out if it is just my device with the issue or if everyone is affected. I am on MetroPCS if that makes any difference.
Trying to figure out if this has to do with Magisk, or maybe my DTIM and Beacon intervals I set in my router. No apps are holding wakelocks, phone is active less than 5% when screen off. I will factory reset if a few people state that they do not have this issue.
Can someone reproduce these steps and let me know if you get heavy standby drain?
1. Enable WiFi Calling.
2. Turn airplane mode on.
3. Turn WiFi back on.
4. Make sure you are connected to WiFi Calling.
5. Check current battery level.
6. Turn screen off and leave phone for an hour or more.
7. Check to see if battery went down more than 1%.
Thank you!
In case anyone else has this issue it seems that the heavy drain was due to a DTIM interval of 50 that I had set on my access point. Setting it back to the default of 1 seems to have stopped the heavy standby drain.
I was thinking of buying a OP6T and using WiFi calling as I have no cell/4G coverage at home to try and avoid standby drain issues I have had with previous android phones. Stupid question, why do you need to enable aeroplane mode? Does the phone not switch automatically to WiFi calling when it finds no cell signal like iPhones do? Surely forgetting to turn off aeroplane mode causes problems. What are your experiences in general with WiFi calling on this phone? What sort of battery drain are you looking at overnight using WiFi calling? Do you have any other tips for minimising standby drain when you have no cell coverage?

I enable airplane mode to prevent the phone from draining looking for cell service that it will never find. It will automatically switch to WiFi-calling but it will still constantly scan for cell signal just wasting battery, all phones operate like this.
Wi-Fi calling works great for this phone. The only issue I have is that MMS for T-Mobile/MetroPCS does not work. Calling and SMS work 100%.
I usually loose between one and three percent batter overnight (about six to eight hours) with airplane mode on with Wi-Fi on and Wi-Fi calling connected.
To minimize standby drain with no cell service just put your phone in airplane mode and then turn Wi-Fi back on so that Wi-Fi calling connects. This tip would work with pretty much every phone.
I hope this helped!
Thanks for the information. Did WiFi calling work automatically on your phone or did you have to contact your airtime carrier to set it up? Can you please confirm that with aeroplane mode on you can make/receive phone calls and send/receive sms messages. I need to stay in touch and have good battery life, not one at the cost of the other. I don’t really send mms messages so that is not a problem. What is the DTIM interval you mention on your router/AP and how does this affect the phone? I will be choosing between OPT6 and the P20 Pro and I am concerned about brightness levels on OPT6 as screen seems very dim. I understand google has made changes to the brightness slider in android Pie but I had to have the brightness at 100% where normally it would be at about 50-60% on other phones. Is this something you find a problem or does the adaptive brightness learn your habits?

WiFi calling worked right away with my phone provider, MetroPCS. All I had to do was use their app to set my E911 number for emergency purposes, I am in the US by the way. Some carriers may have to contact their support to enable the feature for your account, I cannot say for any other carriers than MetroPCS.
I can confirmed that airplane mode with Wi-Fi calling works 100% for calling and SMS. The MMS issue seems to just be an issue with the US carriers T-Mobile and MetroPCS from what I have seen. Just make sure you turn Wi-Fi back on after enabling airplane mode.
You can look up what the DTIM interval is on Google if you are interested in it. Basically its how often the router will include a message to wake up the Wi-Fi on your phone to process messages. I had mine set to 50 or 100 beacon intervals and that was causing high standby drain. Pretty much every router defaults that setting to one so you shouldn't have to worry about that. I currently have mine set to three with no issues.
As for the brightness slider it works great for me. I think it's a little on the right side most of the time, some people say it's too dark sometimes, it's all subjective to the person and how they use their phone. Personally I think the new brightness slider is a huge improvement over the old versions. You have a lot more control of the brightness at lower levels so you are able to better set your phone in low light environments. Also the screen gets plenty bright at 100%. I have not had issues using my phone outdoors in bright sunlight. As for learning your habits with the brightness, it does seem to do that to some extent but don't expect it to be magically right all the time.
Thanks very much for all your help. Have a great New Year.
