Hey all, quick question. I know that Android will default to Wi-Fi if available and not use mobile data. My question is that in this situation, does Android power off the mobile data radios (here, 3G/LTE), and then switch them on if Wi-Fi drops? Or are the radios left on, just not transmitting? I'm asking because I'd like to know if there's a battery impact from leaving mobile data on while Wi-Fi is connected.
Nothing to worry about, I leave mobile data on 24/7 and get a day and a half of battery, and switch back and forth between wifi and mobile data

Interesting. Do you know the answer to my first question though (whether the radio is physically powered off/stops transmitting)? I'm curious about this.

i did some serious thinking about this (not capable of very deep though to be honest) but now i am wondering the same thing.
The radio is not powered off , just doesn't get used if you're on Wi-Fi.
but it's ok to eat fish cause they don't have feelings.....

Interesting. I'd assume that having the receiver on would also draw some power, though, even if just a little. More importantly, do the data radios poll for signal while Wi-Fi is on, because that's what eats power.

Recently I've notice my mobile data will disconnect sporadically. I'm not sure if it related to the phone or service. Is there a way to tell?
BTW, I'm in the Los Angeles area.
I've been having this problem too. I haven't been able to find a fix yet.
Have you tried updating PRL and Profile?

I had the same problem when sprint was doing NV deployment in my area!
My problem went away after sprint was done in my area!

Do you have sleep mode on or data connection checked in your power saver menu?

I've noticed the same here in VA. It'll drop for a few seconds then come back.
I still have a connection, but I am noticing 3G/4G flickers in northern Virginia. Hopefully our markets go live soon (officially, anywhoo).
I've updated the prl and profile and have had sprint reprovision data twice. I'm not using battery saver or anything either. The only thing that seems to keep data stable is if I set mobile data to 'CDMA only'.
LTE phone in a non LTE area has caused me grief. Could this be the problem for you also?
I've been having the same issue. However it didn't start till after I unlocked my bootloader and flashed a new ROM. I think it may just be bad timing but I've called Sprint to see if they are doing any work and I've been told no. (For what that's worth)
I also have a GS 3 & 4 and neither of them are having the issue.

I'm thinking that is the cause of this issue. About 60% of San Francisco has LTE now and I'm thinking the phone just has trouble staying to one tower or another. Still it's a frustrating issue.I didn't have any of these problems on my iphone 5 before or after switching back and forth.

Ok, so have noticed this using the speedtest.net app.
When the phone is brought out of stand by / sleep, my download speed is 3 meg,which is slow , if I turn Wi-Fi off and back on, and redo speed test, I get my full speed of 60-70 meg.
I have tested to see if turning the power savers off make a difference,and have checked that keep Wi-Fi on during sleep is on. Nothing seems to make a difference.
Any comments. ??

I don't use wifi that much so I can't say I've noticed. I have noticed however, when my phone's been asleep, I often have issues with mobile data not being on ... It is fine for large periods of time when I'm using my phone more regular but if I leave it for a while it usually says "Turning On" in settings and often never changes until I tuen it off and let it settle lol.

I have exactly the same issue as you describe. I'm on the Europe version.
Only turning on and off wifi gets it back to max performance....

I don't expect that it is region related. Maybe nobody checks the data speed with speedtest.net....
Is there another app to test your data speed because maybe it is related to speedtest.net?

Tested it with another speed test app and the results are the same.... So it is related to the device itself...
Yep I have also tested with another, and its the same .
Just had a load of play store updates, slow download speed, turn WiFi off and on and then the speed dramatically improves.
Definitely a problem.

UPDATE.
Well, today I did a phone reset...this appears to have resolved the problem.
A bit of a pain, even with HTC backup, it's still taken me a few hours to get everything set up.
Will see if the Wi-Fi remains sorted over the next few days.

I have the same issue with a HTC One bought through Dial-a-phone and on the O2 network. I sent my first HTC One back
for a replacement, but the replacement has the same problem, so it's not a fault with the handset hardware per-se, more likely
the wifi chipset or firmware.
I have also found that the wifi does not automatically switch between access points on the same SSID, i.e while walking
through a building - it just hangs on to the on it associated with first and won't switch to a better AP even if you're standing
right underneath it. Very irritating. I have found the app 'WiFi Fixer' to be of some use in reconnecting. That also seems to
act the same as turning the wifi on and off, so avoiding the low speed issue.
Interestingly, in my testing, while the speed test app has been showing the downstream limited to 2mit, transfers back and forth
to my local NAS have been fast. It's almost as if the 2mbit 'cap' only applies to traffic going through the default gateway (usually
a home router or the like) but the problem manifests on corporate LANs too with sophisticated Cisco equipment, so you can't really
blame the LAN.
I've logged a ticket with HTC which was allegedly 'escalated' but I'm not that hopeful of a positive outcome!

I've noticed that yes the one switches between wifi/3g/4g much more smoothly, but also noticing it dropping those signals much more frequently too and struggling to reconnect if it drops it. As in, I can have a data connection, then none at all out of nowhere without moving, and a couple of minutes later it reconnects.
I was even just sitting here at home where I have full signal on wifi and saw it drop wifi too. This never happened on the previous base... Sigh... Nothing is ever perfect...

I've noticed that my phone is holding onto lte better inside today since the update. It was usually dropping to 3g once I started doing anything.
but it's ok to eat fish cause they don't have feelings.....
I'm dropping calls like crazy lately, but it really started before the update, so I can't say it's because of that.... Sprint really sucks lately, dropping calls left and right, signal dropping out all the time, and slower than slow 3g

Mine got better with the update. I can hold a call for over an hour in my house with 1 bar just like my old phone. before the update it would drop after 5-15 min. Also I am running into far less places where I simply can't use data despite having signal. I think there is still room for improvement.
When I first flashed the update everything seemed to working smoother and seemed to hold a better 4G signal. By the second day my WiFi would drop in and out, my 4G won't hold when I know have full 4G coverage. Sometimes I don't have a signal at all. Like that is my only pet peeve about this phone. What's the use of having the best phone if one of its primary functions doesn't work properly? I'm definitely looking to get something new at this point.
Where can I find the radios/firmware update? I've looked through all the threads and they are no where

I was having similar issues, I think it had to do with the fact that it was an in-place upgrade. I did a factory wipe, and the One is behaving much better.

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.
