[Q] "Mobile radio active" battery drain on Lollipop 5.0.2

Has anyone found a solution for this yet? This thing is draining my battery like crazy. Gets me at the most 2 hours screen on time (half of what I used to get on KK). Tried both CM12 and AICP and both have this same issue.
Here is a link to my battery stats - Cell Standby seems to be the biggest battery user when this Mobile Radio Active is going "nuts".

If I catch it early then reboot temporarily fixes the issue but if I don't then in a day's use this Mobile Radio Active can take up to 8-9 Hours of activity! Please help!

This is still an issue.

Stll an issue in the official 5.1. Weird thing, it doesn't always happen... I get this drain from "cell stand by" like 2 days out of 4 or something like that.
It's pretty annoying since the battery really last longer with Lolli, except when this issue is ongoing.

Usually cell standby draining your battery hard is from a weak signal while on data. Not Wi-Fi.
Look at the graph in the stock battery section in phone settings. A lot of red and yellow for the signal bar would confirm that. :good:

Anyone else have high Cell Standby?

Anyone have issues with high Cell Standby? My cell standby is at the top of my list with "time on 8h 12m" (pretty much my entire time off the charger) and Time without signal is 0% (so i haven't lost connection plus I've been on Wifi at home the entire time)
Ive also only have about 52 mins of screen on time with light use and I'm down to 79%. The drain seems very high considering how I've used the phone. I just don't understand why the standby is so high or whats causing it. Im stock rooted and have r17 Franco Kernel installed, it seemed to have started when I installed the latest r17 but I'm pretty sure it would be a coincidence since the cell standby was always kinda high on my list but not as bad as lately.

If you don't use the phone and keep it away, obviously the cell standby will come first but that much battery should not be drained. I can notice max 2-3% of battery drain from 100% over-night on stock

If you don't charge your phone up all the way to 100%, the battery stats don't reset.
Otherwise I think it's sounds reasonable.
8hr stand by, a little under 1 hr screen, wifi on the whole time.
That's about 9 hours total + wifi for 21% or 676.2 mah used. I usually run with a huge stand by time, not so much SOT. I get about 35%~ a day so I charge up every three days.

If you're on WiFi and cell standby is that high then you probably have a weak voice signal connection. What colour is it on your graph? You can also check your signal level in Settings > About Phone > Status

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.

Are you using the version that came with your phone, or are you using something custom (i.e. CyanogenMod or Resurrection Remix)? Did you see what "supposedly" is the highest percent drainer under Settings->Battery?

Based on that, the only thing that I can think of is to turn down your display brightness (even try setting to auto if you haven't already) and if your cell service is often weak/non existent, then put it in airplane mode temporarily to turn off your cell radio (which will also kill calling and texting though). It also depends on just how fast your battery is draining. How much time are you getting with it on? How quickly is it draining (percentage wise per hour for example)?

It sounds like some of that is just the software then as well. Before I unlocked the bootloader and installed CyanogenMod on mine, I used to see it drain quite a bit faster (especially during standby when the screen was off). A big part of that was being able to change the CPU clock speeds (which I lowered on mine) and adjusting it to where many apps couldn't wake up the phone anymore. When doing heavy gaming though, it's pretty much always guaranteed to drain quickly.

I'm not saying the version you are using, but the actual stock software in general. It's definitely not optimized as well for battery life as it can be in a custom ROM and the bloatware doesn't help either. Using the phone for gaming will also take a hefty toll, regardless of what you are running.

Do you mean 10% per hour of screen on time or screen off time? If you lose only 10% for an hour of screen on, you probably get 8-10 hours of screen on time per charge. I only get less than 5.

battery draining MM droid turbo
Hi Friends; after updating to MM, my droid turbo seems to have a 2000mah battery...done wipe cache partition before and after the new MM, an hard rest but in stanby or in aiplane mode the battery sucks 10 points and more in a few hours...could you help me? Please...
p.s. idle 22% standby 22%...no gps, no bluetooth, no notification, just a few applications...

Hi Friends; since updating to MM, my droid turbo seems to have a 2000mah battery...done wipe cache partition before and after the new MM, an hard rest but in stanby or in aiplane mode the battery sucks 10 points and more in a few hours without doing anything...could you help me? Please...
p.s. idle 22% standby 22%...no gps, no bluetooth, no notification, just a few applications...I tried, after charging to 100%, leaving the phone for some days without doing anything (no wifi, no connection, no signal) and I was surprised to read such draining as in the screenshot.
Anyone can reply and help me? What's the difference between idle and standby? The phone has a stock firmware, never rooted

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy Note5's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

When A 7.0 came out overnight my battery would tell me 2 days+ of battery left with only 1 or 2% drain. As the AT&T updates continued it got worst. I have recently performed a factory reset. It will only drain 8% overnight as opposed to the usual 23% I was experiencing intermittently.
Recently installed the wake-lock detector and greenify. I'll see if greenify is just a battery hog or if it will help.

I feel that my N920A really has good standby life if I don't have any background processes running. I'll lose about 3-5% battery life each night with the phone unplugged (and connected to WiFi) collecting Whatsapp updates with the screen off. My battery drain is really about background processes. I've uninstalled the applications that I no longer use, and those I no longer NEED for weekly use. My battery life was restored dramatically. My phone CAN last an entire day, but I keep my charger nearby just in case one day I'm proven wrong.

Hmm well mine 920I after about 9h went from 100 to 97.

Hi, I'm having the same model as yours which is SM-N920I Note 5 International Version. Can I know what is your current rom that enables you to have such battery saving. I'm currently using pixel experience (Stock Google), No Touchwiz etc, and mine gone 9 hr and battery to 20-30%. Any idea on should I revert to stock rom, or choose another custom rom. Anyway what rom did you use, so I can follow more easy.

back to stock or better rom

why don't you download stock rom from sammobile and flashing through odin ? if not try khonloi S8 rom the smoothest so far. Battery average 3 hours SOT, and standby is more than 15 hours without AOD .

After doing a bunch of tests on my N5, I found out that my horrific standby drain was from having bad cellular reception in my area. I have the N5 (Canadian version) which has no carrier bloatware; however, I was loosing about 15% overnight with Data and WiFi on. Obviously, WiFi takes over, but the phone still tries to scan for cellular data. When I started turning off Data at night, and using only my WiFi connection, that's when I started to loose only 4% overnight, which told me the problem was a bad signal. So I went on and changed my Data connection from automatically connecting to LTE, to automatically connecting to 4G, and my standby drain has decreased significantly.

I'll test the 4G only option, and see if that works for my N920A

My N920I drains 100% to 86% after 8 hours. what is the problem?
Tried rooting, changing kernels and still the same result. somebody please help me or give me a suggestions on the matter. Thank you

Try measuring it in airplane mode. I guess your drain is normal due to poor signal reception in your area. I'm getting very similar drain ~1.5% per hour and -0.3%/hour in airplane mode. Also I noticed my n920p receives much lower signal (15-20dbm difference) compared to my old note 2 in the same conditions.
