Cell Standby Suddenly Draining Battery (CM13 RR) - Verizon Motorola Droid Turbo Q&A, Help & Troublesh

Last night I had a problem with my home wifi (phone couldn't connect--Authentication error). I rebooted the router and it connected. Then I noticed an hour or two later that my phone was warm and the battery drained about 20%. I charged it fully and went to bed. Six hours later and the battery was completely dead.
Cell Standby is using 60%. I wiped the dalvik and cache in recovery and it's still using 60%.
The phone is on CM13 RR (6/22).

It's a Marshmallow bug that occurs when on Wi-Fi and connected to LTE.
You can alleviate this issue by using an app that automatically switches to 3G like Smart Network (Xposed) or GravityBox's smart radio (Xposed), or by turning mobile data off entirely when on Wi-Fi. By doing thia, Cell Standby won't show that "drain." However, MMS (but not SMS) texts will not be sent or received if mobile data is off, with the only exception being Verizon's Message+ app, which can send and receive via Wi-Fi.
There's some "debate" as to whether or not it actually has any impact to battery life or if it's just a visual reporting issue. Me personally, I see zero negative effects of the Cell Standby "drain." If I turn mobile data off, or use the 3G "fix," my battery life is basically the same as when Cell Standby is showing the "drain."
More in-depth analysis of by Cell Standby "drain" analysis here.

I believe I have solved the problem. I reflashed the .49 update and everything went back to normal.

[Q] Battery drain when Data connection on

Have anyone noticed tremendous battery drain by just letting the phone accessible to data connection? I reflashed the entire firmware, did not install a single app, neither used the phone for anything. My device drains 7% of power in an hour by just idling.
However, if I use wifi only(sleep policy:never), I will have up to 80% remaining after a day of moderate use.

[Q] Wifi is chewing through my battery

Ever since I did the LG update from B to D and baseband to 405 I have had issues with my wifi. Two things,
1. After a while wifi looses my home WAN network and will only reacquire it if I turn off the wifi then turn it back on. This did not happen before the update. It occurs whatever wifi sleep setting I use. I am consequently using much more 3G data than before.
2. Wifi now uses ~50% of my battery usage. Overnight it chewed through my entire battery. When I woke I thought I had BSOD but instead my entire battery had been used.
Any ideas what the problem might be?
cheers

How to tackle my Z3C battery drain issues?? I'm fed up

I'm fed up a bit for my Z3 C battery life. This is my second query regarding battery life.
Does keeping Mobile data and Whatsapp running ON even in standby mode drains the battery??
I usually get just 1 or 2 whatsapp messages in an hour or two.
My phone settings-
Always turned off my wifi/ bt/ nfc/ gps/ location tracking/ autoupdates etc. & everything you can think and suggest.
Use only stock custom wallpaper and no live stuff. No widgets. No sd card inserted. With only two hoemscreen wih just 2 shortcuts on each screen.
Have disabled apps which I dont use.
Stopped services of apps which are no longer needed.
No auto sync enabled for any app.
Display brightness is at 30% all times.
*****************************************************************************************************************************************************************
I use only these 3rd party apps-
Status bar mini
Network monitor mini
Whatsapp
Greenify
*****************************************************************************************************************************************************************
My daily Z3 routine-
At night while going to sleep I turn off mobile data, turn on airplane mode and turn on stamina mode. (12:30am - 9:30am)
When I wake up the next day battery is down by 4-5%.
During day, phone runs in normal mode without any stamina activated. (10am - 12:30am)
*****************************************************************************************************************************************************************
The Low-battery mode seems useless as it does literally nothing.
Also, as soon as the battery is 100% charged and if I use phone for even 5 mins the battery immediately drops to 99%, so is this normal??
Even if I capture 5 photos in stock auto mode the battery drops by 1% or 2.
I reboot my phone once a week or in 10 days or when need arises.
Ram utilised is always 1gb. But I dont feel any slowness for any app or my phone usage.
But again I dont watch any movies or play games fearing my battery will deplete in no time.
I use 2G/edge network as 3G isnt available for my operator in the city I reside.
Charging the phone to 100% from 14% takes 3 to 3.5 hours.
I have already repaired my phone using Sony pc companion and also did a factory reset as well but this issue has been haunting me every now and then.
Sony center says the battery doesnt need any replacement as its still healthy and so is my device.
The phones service menu also reports battery status as Good.
I dont know when is Lollipop gonna be out for Z3 but I fear updating to Lollipop as it may pose more issues than doing any good apart from usual gui tweaks & updates.
But just wish that lollipop brings in more relief to Z3 batteries.
It would be better if you also posted some screenshots with your battery usage.

EVERYTHING drains battery, literally everything. If your volume is on max it also drains more then when your volume is very low. (Just an example)
There is a controversy when it comes to WiFi vs 3G which drains more.
In the end I think that it depends on the coverage. For me 3G/4G drains my battery less then my WiFi due to the poor WiFi reception.
That your phone loses about 5% over night really isn't THAT bad, what I do before I go to bed is "Close all" to close all the aps running in the background (It won't terminate WhatsApp's service) and I let Greenify hibernate all programs that I selected.
There was also a talk about charging your phone to 100% vs 99% the first percentage drains fast for everyone so that's why it's maybe better to only charge it till 99%.
With screenshots of your battery usage we could help you more, but as far as I can see there is nothing wrong with your battery.
If you're rooted, try BetterBatteryStats to pinpoint the drain.

Well my device isnt rooted nor I use any wifi.
And also I use Greenify to shutdown all apps before sleeping and also I do manual force stop for many other apps as well.

Cell standby on marshmallow

I've been running marshmallow since the stock images were posted and I always got very nice battery life with doze. As in, I wouldn't have to charge the phone until the next morning. Since last week, however, cell standby is using significantly more battery. Yesterday, I took the device off the charger at 0900, and by 2100 I was already at 25% battery. Screen on time was only 2 hours, and cell standby had more usage than the screen. No matter my signal quality, it seems cell standby is eating my battery. Phone isn't even showing as awake! I also am always connected to WiFi and using T-Mobile WiFi calling.
I know a few users have reported a similar issue since marshmallow, does anyone have an idea of why cell standby is killing battery even though time without signal is 0? Time active is also always under 20 min. Since I'm using WiFi calling, I'd think the phone wouldn't even be searching for a voice signal anyway.
My signal has been worse than abysmal since switching to Marshmallow. I uninstalled Fit, Pay, and Google+ and it got better strangely enough but i still have issues from time to time...

The same happened to me, at the begining with marshmallow (chroma and francokernel) always more than 5h SOT and easy deep sleep... but now, the last night at 1:00AM battery was at 100%, at 5:00AM was 84%... and no wakeloks... i'll take some screenshots
Same here. I swear the battery is draining faster but no wakelock issues.
Plus I believe there is an issue with the signal reporting. Where I know that I get full signal the phone can report zero bars. Switch to airplane mode and back, then suddenly the signal displays correctly!
+1 My signal is terrible anymore, and I certainly was much better on the preview images
At my desk at work, same spot I sit my phone everyday would be in the mid 80s and right now it sits at -103....hit airplane mode and it resets....for a few

I'm having the same issues. Overall, pretty solid battery life but cell standby drainage was high. Been searching forums with no such luck. Sounds like it might just be and Android issue I have to hope gets fixed in an update? I'm using T-Mobile wi-fi calling. I'm in areas with strong LTE signal, but compared to my old phone, the amount of "bars" I'm seeing seem lower and sometimes non existent, although I spent no time without signal.

Battery Drain while driving to work

Hi
Just noticed something interesting this morning whilst driving to work with my huawei p20 pro.
The battery drained from 82% to 78% within a 40min drive to work on standby (without mobile data, location GPS or Bluetooth on). When I am normally at home it drains around 2-3% overnight max.
I have 2G/3G mode as preferred and carrier aggregation disabled
Is this due to it automatically switching to the nearest cell tower?
