Battery used by cell radio in airplane mode? - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

As the title suggests, I am wondering why battery is being used searching for cell signal. Shouldn't the cell radio be disabled when in airplane mode? The phone has been in airplane mode during this entire period. See screenshot below. Wondering if anyone else has experienced this.

Battery drain with no signal

My diamond's battery doesnt last very long as it is but where I work I dont get any signal, and seems to drain twice as fast
Is the fact its trying to constantly get signal thats doing this?
Any suggestions much appreciated....
Rom = Shaks.P v4.00
Radio = 1.09.25.23
my girl HAD the same problem too. i told her that since there's NO signal, the machine will constantly search for available networks. the only alternative to this is to either switch off the phone or put in airplane mode. by putting the phone in airplane mode, the phone will not be constantly searching. have you ever notice that using 3G network uses more juice than that of 2G? she gave it a shot (airplane mode) and the problem of battery drain no longer bugs her.
Thanks, will give the airplane mode a shot
Yes, airplane mode will stop it from searching networks because all communications are shut down.
You can also prevent the battery drainage by turning the phone off or throwing it in a glass of water
If you still want to be able to use the phone (function) you don't want to use airplane mode
Also most ROMs by default have the BEAM "Receive all incoming beams." switched on. Switching it off helps as well.
I also suggest trying other radio's and switching 3G off for phone calls....

Cell Standby

I have the p1c version of this tablet and i'm running 11-20140126-tereceng-p1c. When I check my battery level it says cell standby is the major battery killer of my tablet by far. I've tried to disable mobile data and I've tried airplane mode but with no luck. Is there a way to disable mobile data completely? Thanks for the help.

Huge battery drain !

Hello !
Im using Galaxy Note 5 N920C version and experiencing huge battery draining. The main reason is Cell standby and device idle. Don't have VoLTE on my phone neither advanced calling,tried wiping cache many times and problem still goes on, i don't know what to do almost tried everything.Problem persists even with both 3G and LTE network. Any solution?

I think the problem is that the phone keeps searching for cell signal. Try finding out where it does it maybe house, work or etc. then turn the phone on airplane mode when you are there. My phone did the same thing when I was at school so I would just turn on airplane mode to save battery.
Same happened with me, I thought there is some issue with my phone.
So I sold it and bought a new note 5 and it's still same at my home.
So either put it at 2G or airplane mode.

Cell Standby Drain with Stock 6.0.1 Even in Airplane Mode

i have a xt1254 with locked BL and stock 6.0.1 MCG24.251-5-5. I have suffered from battery draining by cell standby since I updated to 6.0.1. Have anyone seen this and can anyone help?
Here are what I have tried but none of them works:
1. Erase cache, user erea and reflash the stock package.
2. Root, install magisk, install xposed, install mobileradioactivefix.
3. Switch to airplane mode with only Wi-Fi enabled.
I came across battery drain caused by wifi and managed to remove it after resetting network config. You may see the below page for information, and in fact quite a few similar threads are on google:
https://www.androidpit.com/android-marshmallow-problems-and-how-to-fix-them
It occurs to me that after resetting the network config, the problem will come back sooner or later that need a re-reset. And I am not very sure if it works on your cellular problem indeed. But hope the above helps.
BTW, may I take the opportunity to ask a related question, anyone using a stock up-to-date firmware (mine is BL unlocked but not rooted), and the same feeling as me that, while every part of the system show that the cellular is disabled and the device is in airplane mode, the battery performance is about the same as that when the cellular is on? My usage pattern is that, I unplugged the device at 7am, and on working day morning, I turn on cellular for less than an hour and the rest of time in airplane mode, and get to around 90% at 1pm. While I was on outdoor work that requires me to turn on cellular the whole morning, the battery level is about 88%. Given that my usage pattern in both scenarios are quite similar (minimal usage of phone during working hours and basically no voice call in the latter case), is the difference between airplane mode on and off little as that?

Can't disable cell radio

Hi all,
I picked up a Note 3 from ebay on a really good deal. I am not using cellular. I'm only using it as a very capable ereader, internet etc.
So I want to completely axe the cell radio. I turn on airplane mode and turn wifi back on but "cell standby" is still showing battery drain even after wiping battery stats.
Any way to totally disable cell on the hardware end, rename an apk or use ADB?
Thanks,
Rich
Anyone??
