JB tw rom + 12121.prl + Roaming = severe battery drain? - Sprint Samsung Galaxy S III

I noticed this back in LIH beta release, and it's also true now with a LJ7:
http://forum.xda-developers.com/showpost.php?p=32844247&postcount=4
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?

[Q] Weak wifi battery drain

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

Verizon Galaxy Nexus Battery Sucks

I've been having some pretty crappy battery life. I don't know if this is due to the fact that it's on LTE/CDMA or what. I've been using Android since April 2009 when I got my Droid Incredible. I generally keep most settings on and can get a full days worth of use.
WiFi - usually always on, unless it nags me about new networks. I always keep the setting to 'always on' too.
GPS - always set on.
Email - 15 minute sync time.
Anyway, you get the picture. I'm gonna try setting it CDMA only to see if that helps.
Post your thoughts, is this a 4G issue? I don't get 4G at my house so... I dunno if it's searching for it or what. In the picture I have about 6 hours of sleep or so factored in.

[Q] Galaxy Nexus Wifi Issues (Download Speeds)

Had my galaxy nexus for a couple weeks now and the wifi (download speeds notably) has just never been strong for me at all, even when sitting right next to my router.
I have a Verizon Galaxy Nexus LTE 4.0.2 unrooted.
I get good 4g speeds, but my wifi speeds are just terrible.
Here's what I get on 4g:

}
This is what I get right next to my router:
My upload speeds aren't bad but the download is just terrible. And its weird because the ping is so low.
My wifi isn't great in general. It used to be faster but here's what I get on my computer now:
I know there's a radio fix for GSM phones with xxkk6 but I don't think there's one for LTE. Is anyone else having this issue with download speeds or know a fix? Thanks in advance.

T-Mobile WiFi calling battery life

i've been using T-Mobile WiFi calling for a few weeks now, and for the most part battery life seems good, maybe even better than without.
However, last night it sucked 30%+ of my battery with a partial wakelock overnight without me even touching my phone. Anybody seen this before or have an idea on how to keep it from doing this?
Oddly enough, under Better Battery Stats, it's listed as AlarmScheduledService, but just to make it clear I had no alarms scheduled. Under Android's native battery usage display, it first showed up as *wakelock* before resolving into IMS Service.

Ive noticed the EXACT same thing... id go to sleep and wake up with like 40% battery missing... stopped using wifi calling problem went away :\

Signal strength suddenly drops after few some time when turning OFF airplane mode

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
