Cell Standby Battery Drain - Verizon - Nexus 6P Q&A, Help & Troubleshooting

So I recently switched from MetroPCS to Verizon. The day I switched my battery died twice as fast. Cell standby being the problem according to the battery stats. 2nd day, same exact thing. So I did a factory reset. Then the next day the same exact thing. This did not happen on MetroPCS. Also, it seems to only be a problem when WiFi is on, but not connected for most of the day. Which is strange, because I don't see how your carrier would make that a problem. Has anyone else experienced this? Fixed this?

No signal?
Check your cell signal connectivity to see if you are losing signal throughout the day, if your phone loses signal your Cell Standby will constantly search for a signal untill it finds one eating your battery. I have this problem when at work, I don't get signal and my battery drains. I fix this by using Airplane mode when I know I don't have signal. Saves my battery Everytime.

Yeah, would be surprised but Verizon may have worse coverage than the Sprint MVNO in your work area. If your cell radio is constantly hunting, it will chew battery. Have you tried Wi-Fi advanced settings to leave Wi-Fi on at all times, even while the phone is sleeping? May sound counter intuitive, but for me Wi-Fi uses almost nothing battery wise. But like Noland said, if you KNOW you will be in an area of poor reception for a long period of time, airplane mode will save battery. Also check data usage by App. You may have a rogue app sucking bandwidth. Cheers.

Some Verizon members reported poor cell reception with the current radio. I think the January security updates include a new radio. Maybe that will help.

[Q] Crazy high cell standby killing my battery life?

Help!
I'm running the 81xx firmware on a direct-from-dell unlocked Streak.
My battery life has so far been abysmal, and looking at the battery usage screen, my cell standby is usually over 60% while idle is less than 20%, everything else like 2%. This isn't from weak signal, though; I am in a well-covered 3g-only area and my phone has reported only being disconnected about 4% of the time.
Another strange thing is, my data indicator is constantly switching between the H symbol and the 3g symbol.
Anybody know what's going on?
It might be that while you are well covered for 3g, you are marginal for HSDPA and that constant switching back and forth is using your battery. I have not tried it but have a look and see if you can disable HSDPA in settings somewhere and see if that helps.
i'm usually around 40% cell standby.. do u have any task killer apps installed? although people think those are useful they usually do more harm then good.
I have the same problem, and I used another Android phone in the same location (hence same cell coverage) with no such problems. I just took my phone off the charger and had the display on since then non-stop. Cell standby used as much battery as the display!! There's no way that is appropriate.
I'm running build 8102, but it was the same with 6941 before. Can't tell about 1.6 as I bought my streak used with 6941 on it.
What Android version are you guys running? Maybe we can find common denominators.. :/
Edit: here's a screen shot of the battery usage after a while off the charger with the screen on constantly:

Do you think your antenna might be loose or defective?
I can't imagine the antenna to be loose really - but who knows, I bought mine used. If so, I think there is a signal strength value in " about phone" somewhere, no?
What signal strength are others getting? I'll post mine later, I'm on airplane mode right now so that I get some battery life.. :/
For signal strength, I am getting -75 to -95, and 9 to 12 for the two values while riding the train (not subway).
It also appears my battery life is quite good when my phone is in standby and not doing anything... the problem seems to come from net browsing or anything else that uses an active connection... Just browsng XDA is taking about 2% a minute!
Oh and my android is the 81xx 2.1 version with the modaco tweaks

I had really high cell stand-by too. then i installed juicedefender, now my cell standby is down to about 29%.
I think the main thing is that it disables data connections while your screen is off and only turns it back on when the screen is on and unlocked. It also has a setting where it enables data connection periodically to allow background syncs and whatnot.
I'd recommend you guys give it a go, it had almost doubled my battery life!!
Mine shows,
cell stand by 50%
phone idle 44%
it seems quite common on the streak as I read in all the forums. I am on 2.1 stock rom? what's 1.6 like?

Cell Standby

So for the past week and a half my G2 battery started draining super fast and it seems that the cell standby is the problem.
If I reboot the phone and have it on for 10mins cell standby time will show time on being 20mins. How is it searching for a signal an extra 50% of the time when it hasn't been on?
Also it will show that I have been without a signal for 50% of the time the phone has been on when I've never lost signal at all.
So the point of this thread is to see if I have a defective device so I can get it replaced. If anyone can help me out and post their Cell Standby times and Time Without signal percentages after a reboot and/or after a days use I'd greatly appreciate it. Thanks.
I'm glad I'm not the only one that had that problem. I had literally the EXACT same problem you are having, and exchanging my phone for a new one fixed it. My cell standby with that phone was in upwards of 79% and averaged 50% without a signal according to that screen. The new phone sits anywhere from 14-40% cell standby, and although there is definitely something wrong with how the radio on this handles signals, I don't get dropped calls anymore and it spends 0% of the time without a signal.
Another problem I had, and am still having, is that data connections just drop with no warning and I have to either wait forever for it to figure it out (there are no indicators of this status in the task bar, however nothing data wise will load) or put in in and out of airplane mode to reestablish a connection. I know plenty of others who have this issue as well and wonder if you do too.

I did some checking around with other people that have Android phones as well (not just the G2) and they do not have this problem either. The good news is T-Mobile is sending a replacement because this unit is in fact a defect. Thank you Gwanatu for posting.
Guys, can you tell me how to see this cell standby info? I got mine yesterday and the disconnects are starting to irritate me. Behaves identically to my Nexus, up arrow stays for a looong time, up to a min until it starts receiving data.
Still agonizing about replacing my Nexus, so if these disconnects are a G2 "feature" as well, then I'll just go back...
Thanks

A T-Mobile rep told me they are using new/different type sim cards for smart phones and that could be a possible issue if you are using an older one. Mine was about 5-6yrs old.
My cell standby is at 58% and time witout a signal is 50%...
Did a quick google search and found the airplane mode trick
1. Plug in phone charger
2. Put phone in Airplane mode
3. Put phone to sleep for a minute
4. Turn off airplane mode
5. Unplug phone
I did this and now my cell standby is at 14% and time without a signal is at 3%
fwiw my cell standby is 21% since last reboot days ago.
I do not have php and it is well past 15 days...airplane trick no longer works...still sitting @ 41% cell standby...don't know what else to do

Does any one think a factory reset and training the OS would help?
Sent from my T-Mobile G2 using XDA App
ive noticed the cell standby % being higher than it was on my nexus one. cell standby is typically the highest % item in my battery use list (my nexus was always the damn screen sucking up power). if i click it it shows the % time without a cell signal. for me, its always been 0% whenever i check so im not losing signal ever it seems. my battery life is actually quite awesome with this phone so it doesnt seem to be affecting anything really. maybe it has to due with the fact that this phone's SoC is a smaller fabrication and more efficient? that might make other stuff appear to use more power compared to older phones that had less efficient SoC's. just a thought
I just in stalled Screebl lite app. Basicly keeps the phone from going off. Once installed my cell standy by went from 37% to 12%. Can any one else confirm the same results?
Sent from my T-Mobile G2 using XDA App
My cell standy was running at 60+% with no signal running 50%. I did the online chat with Customer Care, and she ended up saying they were going to replace the phone. Funny part is that during the troubleshooting, I pulled the battery for a few minutes, and since then, cell standby has been 39%, with 0 lost signal time. I don't know what that did, but battery life has increased a ton. And a replacement is on the way...may try it for a few days, but this is working fine, so not sure I am going to exchange.

[Q] No LTE + Battery drain after tethering

I got a weird one for you guys. I had LTE on my nexus 4, but after tethering for awhile, my LED started flashing red and the phone got hot. So I turned off tethering, but my LTE became intermittent, and over the course of the next day, I lost LTE connectivity altogether, even if I set it to LTE only, I wouldn't get any signal. This is what I've tried, changing different hybrid radios, changing ROMs, factory restore to original ROM. The other symptom, and the one I care more about, is that my battery now drains pretty quickly, whereas it would last 3 hours of screen time on before this incident, now it lasts less then an hour. And it seems to drain while the phone screen is off. Anyone have any ideas what it could be? Did I burn out my LTE modem?
I think you need a new battery.

I have a feeling it has something to do with the modem. Day 2 with the damaged phone reveals that my signal will go in and out, sometimes it will be on 3g, sometimes on edge (even in 3g areas). If that's the case, a new battery won't necessarily help.
Now 3g is gone completely. I can only use 2g. Anyone else run into this problem?
I had this problem a few years back. It was the wireless provider who was adjusting my internet speeds. After one simple call they stropped doing this and my phone was always connecting at 3G (I don't have the LTE hack installed)

Android OS - Keep Awake and Mobile Radio Active

Hi,
The Nexus 6P has been pretty good so far on battery. Nothing super insane, but enough to get me through a day.
Max I get is 3 hours SOT when I hit 0%...
Android OS is usually in the top 3, and in a 10 hour day, its getting 2 hours of Keep Awake time and about 30min Mobile Radio Active.
Google Play Services is also getting around 45min Mobile Radio Active as well.
Phone is bone stock, bootloader locked, unrooted. Running a handful of apps, even stopped using my Moto360 and disabled bluetooth when not in use to see if that was the culprit.
Any tips? (or apps that help me delve deeper into Android OS and why it keeps waking the thing up)
would also like to know about this, having very similar stats
Similar situation here - crazy battery drain and "Keep Awake" when I have a sim card in (TMo). 3 hours sitting on my desk - not using it - the phone gets warm/hot and Keep Awake shows 1H 16m under Android OS. When I put the same sim back into my Nexus 5 (using the adapter/converter) the N5 battery is perfectly fine.. normal.. no massive drain.
Any thoughts?
Turn off Wifi and give it a try. See if you still have the same battery drain.

Go into location & uncheck all scanning functions
Thanks. I should have mentioned that I already had wifi and bt turned off, and had turned off scanning for both under Locations. I was trying to isolate this to cell signal as best I could by disabling wifi and bt things. I also tried turning off "Enhanced LTE" - and now I'm trying it with wifi calling on (again just to narrow down different possibilities).
I think a factory reset is in my near future - may as well start from completely scratch and see if I still get the same horrible battery drain.
Just reporting back. I did a factory reset - and INITIALLY I thought I was on to something. Battery life seemed better at first, but then I soon began dropping cell signal - which apparently sends the phone off searching for signal chewing up battery.
In my case it's never ending cycle - get signal, drop, search, get signal, drop search.
Yes, I'm in a fairly weak TMo LTE service area, but my Nexus 5 and my wife's Nexus 4 have never had these sort of massive drain issues.
Also, I was in a major metro area on Sat night and the signal kept dropping as well. I couldn't toggle it back on via airplane mode or the mobile data switch. I finally had to reboot to bring it back - and then it proceeded to drop again. Meanwhile, my wife's N4 had no issues.
I went to TMo on Sunday and swapped out the sim - no change. 6P went from fully charged to completely dead overnight (roughly 1AM to 9AM).
So, at this point I'm wondering if I just have a faulty 6P. I'll be calling Google today to see about an RMA exchange :/

Maybe try activating band 12?
http://forum.xda-developers.com/nexus-6p/general/fastboot-activate-band-12-volte-t3239652
I found that my wifi network was causing doze to not work as good. I turned off wifi at night last night and got better results with just data.
My radio is accounting for 88% percent of my phones battery drain. I was down to 60 percent with about an hour of SoT. Not sure what's going on with my device either. I was about to factory reset but don't want to.
Bums me out when I see people getting 4+ hours. I want that action.
I had the mobile active bug also, very close to getting an iPhone.
I saw in another thread that apps like GasBuddy has been causing wake locks like you describe. The issue may be app related. Rooting and installing a battery monitor app should give you more insight as well as wiping and loading just your basic apps to find the culprit because something is definitely wrong.
I get 6 hr SOT without doing anything special and at night I lose 1%, sometimes none if I only sleep for 5hrs and that's with wifi on.

Cell standby killing the battery

recently i encountered a lot of battery drain even without using my phone ( galaxy s8 dual sim ) i noticed that cell standby is using a lot of battery sometimes as much as if not greater than the screen it self which is weird because my signal is ok i dont think ian losing signal
anybody having this problem ??

The image shows the phone was without signal for some time which was about 32% and it will consume power. Don't know the reason behind this, but if phone really had no signal for a long time, then be in another place where there is a good signal and test there. I have seen few times with my old Moto X, that sometimes after using internet via mobile network(without wifi), the connecting would somehow still be open and it would consume battery and the way to fix this, I had to restart the phone.

this is ridiculous ! i never had an issue like this with any of my older phones
best bet do a factory reset and see if it still persists
Same happens to me too. Yesterday I went outside my house and traveling in the city - my battery went from 100% to 43% in 6h40min. I had SOT only 1h. I am wondering if something related to GPS is killing the battery as it always drain very fast if i am moving - but in the other hand it seems that phone radio is draining also the battery a lot. Any advices what could I do?

cell standby is not related to gps and location services i dont think so at least iam pretty sure it is mainly phone network related
Cell standby drains too much battery
I'm using Galaxy S8 Exynos Version (Dual Sim). Facing this cell standby extreme battery drain issue recently. I have tried several options like- reset network settings, restart / power off-on, factory reset and wipe cache partition to see if the problem goes away or not. These things can solve the problem only for 2-3 days. Then after that same cell standby battery drain occurs again. The only thing left is to hard reset. But I don't think this will solve the problem either. These are not the permanent solution. When I first got the phone this problem was not there. For the last 2-3 weeks I have been facing this issue and it is bothering me a lot coz my battery drains too much even when i'm not using my phone. I really need a solid solution for this. Can anybody help? And I hope Samsung will address this issue and solve it asap.
I think cell standby is the worst problem in the S8. It really kills battery. It can make your phone drop 2% per hour.
Same issue here. Didn't have this issue before the latest two updates. Before I had 6-7 SoT and now barely 2-3 hours.
yes, this issue was not pronounced before the latest updates (one or two as mentioned)
Same thing here. After the last update there is a battery problem with standby. Hope they fix it with next release.
same with my s8+ dual exynos
