Yesterday I had my phone on airplane mode all day while at work. I don't have any verizon reception there leading to a dead battery by noon. Around 4PM i got a text message. Wondering if this may have somehow taken 8 hours to trickle from the radio through my phone I confirmed the time she sent the message. Around 4PM. Anyone have any explanations for this other than Google turning the radio on to spy on me at random times of the day?
I placed my Incredible in Airplane mode and sent text messages from both inside and outside the VZW network. None got through until I placed it back in regular mode. I also travel quite a bit and it has never gotten an email or SMS while I had it in airplane mode.
Perhaps, at the time you got the message, you had somehow activated the radio.

I had this problem of noticing my phone is turned off at random times (usually once every 2-3 days). I would pull out to use my phone, and its off. I tried calling my phone to see if maybe it was just stuck in sleep, but it went to voice mail. This is very annoying because i cannot rely on my device to be on when it should be (ie- for an alarm) The only way to get it back on was to either re-install battery or hold down power for about 10 seconds. This is my 3rd SGS and it happened on the 1st one and the 3rd (only had 2nd one for a day).
I just realized today (after the 6th time it happened in 12 days), that it only happens to me at places where i have no signal. It happened at work 3 times (where i get no reception), and once in the forest where i was bikeriding. I was in an area that showed no signal, and shortly after the phone was off. (it doesn't make any shutdown noise or anything, I just realize sometimes the phone has randomly turned itself off.
Could reception have something to do with this? Now that I think about it, the 1st phone i had also turned itself off at work....never at home. Will 2.2 fix this problem? Any advice would be greatly appreciated.
check your battery
did you flash any ROMs ?
Were you using SetCPU at all?
SetCPU mischief
My galaxy s was having to be shut down and having to have the battery removed to turn on again in all sorts of situations and I blamed all sorts of causes but in the end it came down to various clock speed issues. Now I'm running a minimum of 200
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?

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.
For everyone using the Xoom data plan and placing it in airplane mode, it may not shut it down. 3x over the past week I have been traveling on the train with my Xoom in Airplane mode and wifi on (was afraid of data usage). Well I was getting "Dings" for email. When i looked, it had full bar on the VZ network and was still in "ON" mode for airplane. Switching Airplane off and on rectified this issue.
Has anyone else experiened this? It is just something to be mindful of.
I returned my Xoom (VZ could not get me hooked up to my VZ) and am getting the wifi one next week.
Fortunate for me I haven't had this issue
Ii have my 3g off all the time,... only turn it on when needed
Since airplane mode is actually supposed to turn off wifi as well, I suspect turning wifi back on can sometimes trigger the radio to activate since you technically are no longer in airplane mode.
That said, if you are normally in a good wifi area I would recommend setting the wifi sleep policy to never if you can.
I'm gonna bet anything the bar you saw was actually WiFi and you'd just inadvertently associated with an open WiFi connection while on the train.
FWIW, I've never found my CDMA radio set unintentionally out of Airplane Mode (where my Xoom stays 95% of the time).
Something very curious has happened the last week or so.
The Wifi stays on, even when the phone is in sleep mode. It is evident when I unlock, the wifi symbol on the status bar doesn't bleep (reconnecting), but stays solid (connected). Of course that could be an operating system displaying error, but it's not; functionality is there, wifi stays on, device connected to the internet. And I'm not talking about the short amount of time that the wifi stays on after locking the phone. I'm talking I'm receiving notification etc as if I was using data.
I noticed it when, after waking up in the morning, I realised a massive battery drop (from 65% to 27%) overnight, although I keep my phone on airplane mode at nights.
As I haven't recently used any mods, regedits etc, and I haven't updated or flashed any rom (btw I'm on debranded stock 8107, with KK2), I can attribute this weird but very interesting behaviour to 2 possible things:
a. I installed some app, possibly homebrew, that somehow (even the dev didn't know about that) keeps running keeping wifi awake under lockscreen
b. Maybe it's because I'm on Airplane mode. I kept on being on Airplane mode from the moment I noticed it (as I have input my SIM to another phone). I should note though that there is a sim in the phone, I'm just on Airplane mode. Is that a known feature? Wifi stayin on under lockscreen on Airplane mode? I don't think so, as I would have noticed all that time (I keep my phone on that mode a lot).
That behaviour has persisted after soft-resets (reboots) and battery charges. The only hardware change I made the last week was using a non OEM replacement battery (the ones that reboot the phone when connected to the charger). But I'm using the original battery.
I should note it consumes about 4% of battery life for every hour, quite viable.
thats weird, but to some ppl, like me, i'd be happy if this happens, would love wifi staying on in sleep mode.
but, the opposite happens with mostly everyone
Even more curious thing that I found out today. When the phone is SWITCHED OFF, and wifi was on before switching the phone off, I have battery drop (almost the same as if being switched on with wifi on, around 3-4% per hour, in my instance from 43% went to 11% when I switched the phone on).
I don't know if the (original) battery has been messed up, so the battery index is not reliable (the reason I bought replacements was that in a span of 1 month, I was not treating it right, a lot of charging, heavy operation simultaneously, resulting in excess battery heating etc), or for some reason the use of the fake battery messed up the software part (both battery metering and WiFi stayin on)
I'll do so more testing and I'll report. Has anyone tried to go to Airplane mode and switch on Wifi, to check if it stays on under lockscreen?
It stopped today... weird!
... And it happened again, this time I think it might have been triggered by Audible, I might make a video as a proof.
EDIT: I was making that video, and realized on cam that it stopped happenning, and then I realized I had flashed beforehand the KK4 firmware. What a douche! If it happens I'll try to capture it on camera
When the data connection is OFF (like when you activate airplane mode) wifi remains connected even when you lock the phone.

No that doesn't normally happens, unless you have an app running under lockscreen and using WiFi (like a music streaming app)
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.
