i just flash the new UGLA4 radio and im not sure about the results. i have some screenshots to help explain my situation. my house is in a low reception area so all the yellow in the Network Signal is very normal.

as you can see in the second pic my time without singal is very high, but according to the first pic i only have 1 tiny red spot in the Mobile network signal indicating no signal. So which one do i believe? is the time without signal count weak signal in the 56%? Everytime i check phone status it shows that im connect to my carrier Fido. Battery usage is also very good, i lost about 3% last night and have 49mins of screen on time with this charge.
I have my signal in the status bar being reported by dBm and the lowest is 113 dBm, maybe when it hits this level the phone considers this in "Time without Singal"? But even at 113dBm is still shows that its connected to mobile network.

I've noticed that if I leave my phone in an room that has a weak wifi signal, my current use is always around -100mA a minute whereas when I have a strong signal it is only -6mA. I have tried multiple 2.3 roms and they all have the same behaviour (haven't had time to try 2.2). Is there any way to just drop the connection when it's weak? I've noticed it happen by itself sometimes but it stays with the weak connection for long enough to cause significant battery drain. I tried looking in tasker but there is no wifi strength variable
On [ROM-AOSP GRH78C] Oxygen v2.0-RC7:
Settings > wireless connections > wifi settings > wifi policy set to "go to sleep when device sleep"
And you are done _ only 14% drain on wifi with poor signal after 10 hours powered on. Hope it helps you
My last piece of work

I noticed this back in LIH beta release, and it's also true now with a LJ7:

If you use a Verizon roaming prl like 12121 (not roaming - Sprint 3g, roaming - Verizon 3g), and then force roaming with Roam Control, the phone battery drains very rapidly.

Here I lost nearly 30% battery under 2 hours with 6 min screen on time and 6-bar signal strength (to a Verizon 3g).
This does not happen if you use 00001.prl, which just connects to Verizon 3g towers by default. The battery drain under those condition is roughly the same as with a good signal on Sprint.
Does anyone else experience this?
How do you fix this?
I need help figuring out a way around this.
I have a widget showing my connection status in Zooper as H, E, G, LTE, etc....
But sometimes I have a DC connection (duel connection when the phone is connecting to the tower twice to increase speeds). This screws Zooper up and instead of showing DC in the widget it shows NONE. See the orange baseball jersey at the bottom for what I mean. Look at the signal bars at the top to see what the phone is reporting its' status as.
So I have an active data connection but Zooper is reporting that I don't. Is there a way around this?
Maybe a way to force Zooper to report 2G, 3G, 4G isntead of E, H, LTE? Or just force it to display something other than NONE when the phone is in a DC status?
(See screenshot in next post)

I don't know why it's tiny. It's clickable to make it bigger....
Sent from your phone. You should be more careful where you leave that thing.
For past few days I am getting sudden signal drops on my pixel 2 xl on LTE.
I found it out when I restarted my pixel, at first the signal strength will be around -85dBm to -95dBm and I'll get good speed but then suddenly after some random time it drops to -100, -105 and the speed degrades drastically. The signal strength never recovers back to -85dBm to -95dBm.
The time to signal drop is completely random, sometimes its 2-3 mins some times it 20-30 seconds. Does anyone have idea around this ? Is this because my phone is switching towers or is it because of software issue ?
Can anyone help me out to debug this ? any tools, any app, any advice, any posts will be really helpful.
I tried to check network info by *#*#4636*#*. I didn't find any differences adding the screenshots here as well.
Good signal

Poor signal
Before you say I can't, I'm thinking hey, why not up the receiver gains and transmitting power or manually select the lower frequency bands in my phone? Like make an app to switch 4/3/2/1g, select which bands allowed, select transmit power, and receiver sensitivity, all in one app?
I think this is a great idea for traveling into rural canada! What do you think
Without restarting btw.
Welcome to XDA!
I, too, often suffer from weak signals in far distant rural places.
But, the thing is, little bars are good, but what you really need is good signal to noise ratio.
There are many apps out there that will let you look at what band, frequency, signal strength and signal to noise ratio.
This is all a bit cooperative too, there's no reason anybody should be transmitting at more power than necessary.

You want a better signal? Move around a bit while checking your signal.
