So I am using a Nexus 6 on the Latest Tmo build (28E?) of Stock Rom and Stock Kernel Rooted, Encrypted.
Since the update that enabled wifi-calling for the N6 I have taken to setting my phone to airplane mode and turning on Wifi only to save battery since the signal at my house bounces back and forth from LTE to 3G and that murders my battery. Most of the time the signal strength graph shows blank and battery app correctly shows the cellular radios as having no on time. However, after being idle for a while (it would seem) the graph begins to show the signal strength as Red (no signal) and the cellular standby shows up in battery usage with the radios as being on (with no signal) and "active for a few seconds". Toggling airplane mode on and off usually restores them to showing up as off. Other times I never notice and it stays on for a few hours and goes back off on it's own. My main concern is that it seems to be activating the radio on it's own, my minor concern would be that my battery monitor app shows that it's using the battery. What could be causing this? I don't think it's a reporting glitch, because it shows up in both the system battery panel and a 3rd party one. If anyone has any thoughts or could point me towards a tool that could help me figure out what's turning on the radio when it's supposed to be off, please let me know. I've included photos from today showing what I'm talking about, the phone has been in airplane mode the whole time in these photos.
Thanks so much!

I think your issue is one of the reason why I cannot get Wifi Calling working at all. No matter what I do, my phone is holding onto a cellular network. Still trying to figure this out.

The best I can tell, "Android OS" is the only thing that shows any mobile packets sent or received so it's got to be a system thing.
If you have the myT-mobile app installed try uninstalling it I found that app totally screwed with my Nexus 6, turning WiFi on when I had no desire to use it.

Unfortunately that's not the fix. I don't have that app installed. Tmo is sending me a new SIM as I am also randomly having Wifi calling drop in and out even while my wifi is connected.
Does anyone know any app that would let me see specifically what app is engaging the mobile radio?

I am running Fresh 2.3.3 with baseband 2.42.01.04.27 and for some reason, my 3G is not working. I have tried getting the stock radio and updating my PRL (my PRL version right now is flipz_01). Nothing seems to working. Can anyone help me with this?
Thanks a lot for any suggestions

Well 3G turns off when WiFi is enabled, but that is not my problem, my 3G just doesn't work, I have to rely on WiFi..

after I rooted my phone, the 3g didn't work. actually i'm not even sure if my 3g had ever worked before that. it's stuck on 1x.

Put the phone in airplane mode and leave it there for a minute or so, then turn airplane mode back off. That refreshes your phone's data connection. Then also try updating Profile in the Settings->About phone->System updates menu -- that refreshes your signal and data profiles with Sprint towers.

Thanks, but it didn't work... this is getting frustrating! I've tried everything! At least they're sending me a refurb, hopefully I get a dust filter this time around, too (and a "with Google" sticker on the back!!!!)
One of the big complaints from all published reviews is the lack of battery power - about 4 hours maximum. I have an idea I to present.
I have the T-Mobile version, but I use my S7 at home; in fact I never activated the device on T-Mobile. I think that part of the problem with battery drain is that one cannot turn off the 3G modem. The S7 automatically disables the connection to 3G when the WiFi connects, but the modem is still working (there is still a signal strength on the task bar).
From past experience with phones, that 3G modem drains a lot of power.
Does anyone know of a way to disable the modem itself? I'm not interested in rooting at this point, but maybe there is some setting I am missing?
If you load DJ_Steve's S7 ROM, there is a hack to disable the RIL. That gave me much better battery life.
I just leave mine in airplane mode with no SIM inserted, enable and disable wifi as needed.
First off, what's RIL?
Second, I've also heard that the cellular is trying to connect on the software side. Any truth to this?
I'm wondering how this tab might fare, battery-wise, with it not pinging for a cell signal and 3G (or 4G, depending on the signal you get, or both and only 1x active) off. Can you set it so only one radio is getting play? Also, can you set profiles so that one gets used over the other? Example:
Screen off = 2G only
Screen on = 3G only
Internet apps (such as browser and YouTube) = 4G only

One of the posts above indicates that he is using a hacked software version, and the battery life is indeed much better without 3G.
Using airplane mode would work if I was only using the device to read books, for example, but I generally use it for online work.
I think the replies confirm my suspicion that the 3G modem is drinking the juice. Not too much of a hassle since I keep it at home next to the charge cable, but (especially with that non standard charge cable) it will not be so good outside the house (unless one is using the T-Mobile 3G, but that takes $$).

I use mine similar to this but I have a sim card in as well. I have a widget for airplane mode and one for wifi on my main home screen. I have airplane mode and wifi enabled most of the time but when I am out and need data (not very often) I just disable airplane mode for a short time.
This works well and the battery life is more like a minor inconvenience.
To do this same thing manually I'm sure juice defender ultimate should work since you could set up profiles for wifi, 2g and 3g (disclaimer: I haven't tested that idea but some people on this forum have juice defender ultimate and might be able to comment)

The problem is that when the WiFi is on, so is the 3g. I confirmed this with my battery widget; 57% of the battery drain was due to the 3g modem IIRC.

If you activate wifi by turning airplane mode off then the 3g radio will stay on in the background while you are using wifi.
If you turn on airplane mode then wifi you will only have wifi active. Just make sure that the airplane mode symbol is on in the top right beside the wifi icon.

Thanks, I will try it tonight! That should improve my battery life a lot. I'll report back.
Wow,
That worked great. I didn't realize that flight mode did not override all radios. Thanks for the tip!

This has also worked for me with the SIM inserted. I get great sleep times with new OTA upgrade left at default settings and keeping the S7 in airplane mode, unless charging. I only turn on wifi when I need it.
Also very important: if you're using the S7 only with wifi, turn background sync off from the power widget, when you are setting the tablet aside for some time. I believe this is where the battery drain actually occurs. If background sync is left on, the S7 continues to try to update location services and your various accounts, even though airplane mode is on.
I have "slept" the S7 (airplane mode with wifi off and background sync off) when I get to work at about 90% charge and come back to it at the end of the day at 75%, ready for the commute home.

I don't know why, but this is a consistent problem and it's getting annoying. I will only have bars, but no wifi or internet connection. This just randomly happens and I don't know what triggers it.
I have to turn airplane mode on and off to fix the problem. Is there something that is causing this?

What happens is data and wifi disappear and if I hit wifi it won't turn on. I have to turn airplane mode on and off and it starts working again.

I have had the same thing happen,but only once or twice,I chalked it up to my home WiFi threw Comcast ,I've been having major problems with my Comcast modem dropping WiFi or to slow of a connection,think I have to replace the modem just been to lazy,but I have the smart network switch on in my phones wifi settings so I thought maybe from the signals switching so much it froze or something,but yea it did same thing I had no lte or 4G next to my carrier signal,the wifi was not allowing me to turn it on,or scan for networks,wasn't even showing any so I did the same thing hit the airplane toggle and it came back.

Sorry i have no others solution for it.
I just posted a thread about the EXACT SAME issue. It only seems to happen overnight, but when I wake up in the morning my wifi has been turned off and my 4G LTE isn't working. When I try and toggle wifi back on it gets stuck and never reconnects/turns on. My solution has been to restart the phone.
I'm thinking since this seems like a rare problem, that this is a device-specific issue. I'm going to try and exchange mine this weekend due to this problem and hopefully get a properly functioning GS5 instead.

Have the same issue (made a post about it already in this forum). Usually happens when there is a large fluctuation in signal. Grocery store where I get no service results in no service when I leave the store as well. Have to cycle airplane mode like you described.
WiFi hasn't done it yet.
Another forum member suggested it may happen if using an older style SIM, which I am (from my S3). I haven't been up to change it yet. What SIM are you guys using?
http://forum.xda-developers.com/showthread.php?t=2744472
I typically have this happen when I'm at home at night, while my phone is plugged in and on wifi. Just disconnects at some point overnight.
I'm using a brand new SIM provided by AT&T when I upgraded in store.
Very strange issue and is random. For instance, it didn't happen overnight last night.

My S5 just started dropping data randomly and causing my battery to drain with almost no usage... I tested using Skype in a good 4G LTE area and will start out with 4 bars and the 4G LTE icon but as soon as I try to initialize a test video call over Skype the signal immediately drops to either no bars at 4G or it will go straight to E!? I haven't had this issue in a long time and it just suddenly started. At first I figured maybe they lost a tower but now this is going on almost a full week. I've got unlimited Data so I know that's not the issue, it has a brand new SIM... I'm going to AT&T and see if they have an answer or if they'll swap it out. Annoying!
Also annoying that sending a simple text will fail... ugh no root and now no data! :what::banghead:

I've had this happen several times, but only at my work. Reception is poor at my office, and the company WiFi requires browser-based login each hour, which I switch to many times a day.
The phone basically stops using all radios EXCEPT bluetooth, showing a circle with a line through it. I've been rebooting the phone to restore connectivity, but will try toggling airplane mode next time. I haven't noted any strange battery drain.
I haven't seen this issue when wifi is disabled.
I didn't notice it locked up a few days ago and drove home where cell reception is very good. The phone didn't recover until I rebooted it.
I have a brand new SIM from ATT and use a Gear 2 (which is greatness, btw)
I've done the following:
1. disabled the damn ATT hotspot app
2. Disabled/enabled the Wifi connection check setting
3. Did a full factory reset
This is getting close to a deal breaker for me.
As an update...
I have this issue basically every work day with the aforementioned environmental variables
Today, I:
Disabled Bluetooth (left the gear at home)
Disabled wireless
Switched radio to 'LTE/GSM/CDMA Auto' with instructions in this thread
The radios haven't locked up and reception is much better.
I'll try leaving WiFi/BT on and use my Gear again next week.
For anyone who is still interested, changing the modem setting seems to have resolved the problem for me. It also improved connectivity in weak areas a good deal.
Unfortunately you must enter the key sequence to toggle the radio each time the phone is restarted.
Hello,
I've used my Mi A2 around 2 weeks now and I'm really satisfied with the phone. However, I got some annoying issue about wifi. When the signal strength of wifi is not so strong (below -70 dbm), it tends to disconnect for around 10-20 sec and then reconnected again. This happened to me like 10 times since I got the phone. And wifi works perfectly without disconnections when the signal strength is strong enough.
Does anyone experience this issue? Or I got a defected device?
Thank you
Same here, sometimes it just disconnects ...

It is a normal stock android behavior, because android detects that signal of wi-fi is to low, and tries to switch automatically to GSM mobile data, or to another wi-fi if it is available in the area.
I don't have this happen but wifi signal is strong and also; gsm data is turned off.
That *may* help to turn that off possibly, as it obviously can't (now) switch to it?

Even if mobile network is off? Is there a way to change such behavior? I tried to find in the setting but what I just found is Aggressive WiFi to mobile handover, which was already turned off.

I think that it is called smart wifi, or wifi+ option in other types of android OS, and here it is just a automatic option in stock android i guess.
I don't mind it, because it will change my wifi router AP if it get stuck, and need an reboot, so it will automatically switch to another closest one that works.
You better think of some way to get a better signal then to turn off this function.
Try with aps like this on the link.

The thing is that wifi also disconnected when there's no other nearby networks to switch to. I did something to get better signal in my room but this still happened sometimes.
I have this strange issue that has been with me almost since the beginning. I haven't been able to trace when it happens, but it now seems almost 100% of the time.
I only have WiFi in the house (wifi6, if it matters). If I go out, I only have 4G (I left only 4G and disabled 5G). I have no data until I put the phone into airplane mode and back, or I disable and re-enable mobile data.
Same thing when I go back in the house: no data until I disable and re-enable WiFi.
I've disabled the option for 'always-on mobile data' or similar, it's quite a battery drain if there's no cell signal.
Seems like a very strange bug, I don't have this with any of my other phones.
So you have both WiFi and 4G enabled and they don't switch seamlessly?
Exactly. I always have to restart each one of them, usually by toggling airplane mode. Was wondering if anyone else ran into this issue.
Ok this really is strange. There are 2(!) different toggles to enable data switching between WiFi and 4G, but for me it works flawlessly without them! As soon as I get out of my home WiFi range, 4G kicks in, and when I get in range again, the phone connects to my WiFi...
Hi, i have this problem too but it's not always.
I have a wifi 6 router too.
I also have problems switching from wifi to 4g. Need to toggle airplane mode on/off. 5g deactivated. No wifi 6 here.
I always assumed my vpn is causing problems during the switch to 4g. But hearing others have the same problem i would assume its zenfone problem.
I never had any issues in this area with my ZF8. With the option to have cellular always on I could walk out of my WiFi zone during a video call and no drop or short pause would appear.
With this off the network need a few second to work, and some apps need to be refreshed/restarted to gain connection. Never needed to toggle connection for this to work.
Maybe a reset would be enough or check for updates.
Ah, exactly! It does not necesarily need a network restart, but some apps just lose connection for a while, which can be from a few seconds to >1h. Which is even more weird as the icons are showing full connectivity. I would go out of the house, do stuff, come back later and I would only get the notifications when I'm back inside the house.
Rarely I had the connection drop completely (no signal) when switching, but I haven't noticed this happening since the last update.
