WiFi and LTE at the same time? - Sprint HTC One (M8)

Does anyone have a issue while being on WiFi and the LTE is still being didplayed? My device does this is there a way to eliminate the LTE while being on WiFi?

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 Im struggling to figure out what that means?

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.

Moble Data Disconnects

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.

4g issues on Optus network

This is an ongoing gripe of mine. I'm wondering if it's just me or if other people have this problem. When I'm on 4g it intermittently turns off data for a few seconds. The 4g icon goes away and comes back a few seconds later interrupting my connection. Only happens on 4g. If I set the mobile network to just 2g or 3g I don't have this problem. I've tried lots of different modems. So I'm wondering if it's an Optus thing or an issue with my phone? ?

probably poor coverage of 4G network
Why 4G when 3G is enough for watching video etc etc?
And it drain more battery also

I'm literally right next to a big city. Its not a coverage thing. If I have a 4g phone why not use it. I get about 24 hours of battery life from it so that's not an issue

LTE

Wondering why if I leave my one set to lte only it holds it with no problems but once I change it to the regular settings is mostly on 3g?

TRUE I forgot to mention *#*#4636#*#* here I chage it to LTE only and just to clarify there will be no voice.

I understand if set to LTE only that it "holds onto LTE better" I suppose, but is it usable? Once the LTE gets to around -120dbs on the One it is unusable I read. Sometimes at my work it will be on LTE but the minute I start using and significant data it drops to 3G.

Significantly reduced signal strenght 4.3 or Sprint's bad timing?

I updated to 4.3 just now and my lte signal dropped to 1 to 2 bars, from a constant full bars. I noticed the performance is equal, meaning it may be just a difference in the sensitivity of the antenna's display of good signal however, it drops from lte a lot and stays in 3g. Has anyone verified the changes in the new modem? Any other bugs I should be aware on the 4.3 update? Also, Dashclock widget doesn't work on htc's widget lock screen.
Looks like before the bars were for voice and now they represent data. That's the way it is in AOSP.

I imagined since there were no changes in performance per se. I just wish I could restrict my one to lte only. Either 4g or no data.

I work relatively close to a 4G LTE tower before updated it showed full 4G with fast speeds, now it shows little to no 4G and would switch to 3G. I tried to Factory Data Reset with PRL and Profile Update and still shows the same, and I'm running all stock no root, and I'm pretty sure it's not the tower.

This is correct. You can verify this by connecting to wifi and then disabling mobile data. Your bars will instantly change.
I like this change. Now I can see that it is not possible to have more than 1 bar of 4G pretty much anywhere in my area. No wonder the speeds are so average and I almost never get 4G, the Sprint towers are all so far off the main roads that by the time the signal gets there it's weak. You can get full bars... if you drive up to the Sprint call center in Bristol, TN.
Before this change it was a lot harder to tell whether you were getting good 4G or 3G reception.
Edit: I just want to say that the reception itself is largely unchanged. When the phone goes from 4G to 3G, nothing will make it go back to 4G except toggling the data off and on.
Just to throw this in the mix. I live in an area that never had 4g but after this update I have it now. My signal strength also shows the one bar but coming from 3g only my connection now is 4g and has increased significantly. Maybe this new radio has a factor that extends the overall 4g coverage? I guess it could be just timing and 4g was opened up in my area but like I said I now have it after this update.

[Q] Idle at UMTS instead of HSDPA

Running 4.3 with Sense 5.5, my HTC One never idles at UMTS (3G) when running in 'WCDMA Only' mode. The statusbar indicates the 'H' symbol while idling and connected to HSDPA in settings. This impacts my battery negatively, is there anyway to force to phone into UMTS when data transfer is completed?
Factory reset does not fix the problem.
Bump, in case no one saw!
This is controlled by the operator, not the phone

Pardon my ignorance, but what's the difference? Where I live (Australia), all 3 terms are interchangeable. Our 3G network is HSDPA.
How do you know there's a battery drain caused by this?

I thought so too, but I've seen alot of my friends using the exact same plan with the same operator and still get the UMTS idle. This makes me believe the APN settings somehow affects the result? (Or SIM-card?)
@deeevan Before I purchased the One, I had the same phone as one of my friends (same data plan). I had HSDPA idle and he had UMTS. Simliar setup and my idle drain was not even close as good as his.
