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.
It happens only when I turn on 3G or I do some installing or I play a game. It says there's low battery and the phone starts shutting down. I've rooted and tried various ROMs but still nothing. What could be the problem? I don't think its the software because I tried rerooting and hard resetting. Any help would be great!
Well it says low battery then it must be because of low battery. Maybe your calibration has gone wrong. Just recalibrate your battery and check.
Nope it's definitely not because the battery's low I charge it to 100% then for maybe 2 hrs its fine. But once I turn on 3G and use it for 5 mins it automatically shuts down. If I try turning it back on it does the same thing what can I do now? I tried to recalibrate the battery many times still nothing. I'll try some more but what else could be the problem?

Try changing kernel?? Increase minimum frequency. Maybe. If problem is still there. Flash your regions stock ROM and go to service center. Replicate the problem there.

Yeah I think I'll take it to the service center but before that I'll try what you said. Thanks for your help!
What if you keep the phone plugged in with the charger and then turn on 3g or install something? Does it turn off even then?
If it does not, the problem is with the battery so replace it.
If it turns off even when charging, something else is causing the problem so take it to the service center.
dude i have had the same problem. i did send it to the service center - will get it back tomorrow if not, then for tuesday for sure..i know what your problem is .. your phone does draine the battery very fast - if you do something, or not isnt it? then when you swith your data connection on, your phone drains the battery withing 5 minutes to 0%. in reality its not a battery problem - cuz i tried another battery of a friend and the same thing happend again. but the battery of my friend isnt bad. :S

Yeah that is exactly the problem I've been facing too! In 5 minutes it switches off I've even tried different ROMs. Well since you've given yours for service could let me know how it goes? Thanks.
Yes. I reveived it today.. seems like the problem still exists -.- i dont see any changings.. it looks like it was just a waste of time to send it to them -.-

have you tried changing the battery
I have the same problem since one week (shutdown while i use 3G or Wifi, but battery is full !)
Revert to stock ROMs doesn't change anything, i've tried o lot of them (was on cyanogenmod before)
I probably get the Galaxy Nexus next year ; but it's a very very annoying problem..
I can't do anything (no calling, 3G or wifi using, pictures taking..)
Please help us.. if it's possible
Yeah I tried my friend's battery but still I have the same problem.

Oh that's not good but I'll take it to a service center asap and hope they fix it. Otherwise it's time for a new phone!
Hello Everyone.
There is a battery drain issue in in cell standby and I think I just solved the issue. Let me go back to when I last experienced such an issue. It was when I flashed a ROM for my SGS1 Captivate called Cognition. There was a bug that left wifi not only on but it was active during sleep mode.
http://forum.xda-developers.com/showthread.php?p=12294219
It was later solved by the Dev and the draining went away.
What is different here is that the SGS3 only has this bug when wifi is on. Look at my battery charts when I have wifi on and wifi off. The red area shows the slope with wifi and the blue area shows it without wifi. This is during standby times.
So is this due to the wifi dual banding just taking up more battery? Or is the phone not properly tuning the wifi down in standby? Solving this issue is out of my hands now and I will have to hand this over to someone else.
For now, change your wi-fi sleep policy to shut off when in sleep mode.
EDIT:
So I think i figured out why the wakelocks are happening. Other people have the problem with dynamic IP addresses.

To say that i would also like this "bug" to be solved

hi slim,
I agree with you here as well. However I've not noticed any battery drain. I've got about 35% left after good full day of use.

I'm experiencing some kind of battery drain too with sgs3, but mine it's not wifi related. I have as first voice in battery stats page Cellular Standby. I mean, it's almost impossible it drains more then the screen!
Anyway, giving a look at your screenshot, I can clearly see some areas you didn't red boxed when wifi was on, screen was off but battery drain was not terrible at all.
How do you explain them?!

Yeah, I mean my battery life is still good, but I know it can be better. Now that I made it turn wifi off when it's asleep the battery life, the slope you can see there in blue, is a lot better. It's not so slanted and draining as quickly.
A lot of other people that complained about bad battery life I noticed the same trend, it's their wi-fi also. If you notice the long blue line on the bottom, that's when wi-fi is active and those extreme slopes have to be caused by wifi. Cell standby shouldn't be draining the battery more than the screen I don't think.
It's either wi-fi, the radio or both.

I don't know, I guess that is when the wifi properly shuts itself off.
When I look at my screen while I'm not doing anything at all I can see the orange arrow on the wifi on, and it stays on even though I'm not using the internet or anything. What can that mean? Is the orange arrow "uploading" or "downloading?"
EDIT: It's downloading. And I set the wifi to shut off if the screen shuts off. The Wifi sometimes shuts off. But right now it refuses to turn off even in sleep! And the orange arrow is lit up!
How do you get the wifi to shut off when the screen shuts off?

It's there in advanced wifi settings.
Did any of you people tried flashing different modems to resolve this?
《tapatalked from galaxy s3》
If you turn off the wifi then wont it just use the normal data connection and so use more battery? I was led to believe that using wifi was less demanding than say 3g.

Yes that is correct, but read my OP and the thread I posted. A wifi bug is the wifi not powering down in sleep mode. It stays on at full power during sleep and drains your phone.

I tried a couple of modems, but in vain. Cell Standby is always much too high. Wifi is beyond good and evil.
I would by now also lean towards a bug. Unfortunately I'm not a Android dev. My knowledge ends at developing apps.
I am satisfied with mine
ive noticed smth:
with Droidwall blocking everything -> still wlan sends smth & causes traffic
hows that possible? u guys can experience the same?
under 3g/edge and droidwall everything blocked: no traffic anymore -> everything is ok!
Have any of you guys tried easy battery saver? One of the features is to disable radios when screen is off. I wonder if it is more successful in doing this than the built in setting.
I got the same cell standby problem so I went ahead and flashed Omega ROM, yesterday was my first day full with that ROM and the result was quite good. I ended up with about 45% battery after about 15-16 hours. Well I'm on wifi for like 3-4 hours though.
Drain caused by exchange sync process. Kill this process and see how battery life will change. Sorry for my english.
Curious, which F/W are you on? I was getting oddball WIFI battery drain using an older LE9 insecure kernel to root at first (WIFI would actually shut off and come back on after coming out of idle... even though I had it set to "always on.")
Completely went away after I flashed back the stock LEF kernel that my phone shipped with.
For reference below, no drain issues during idle with WIFI left "always on."
Hi all,
New to the forum. Sorry if somebody has already posted something similar. Tried to search but could not find any.
The reason I am here:
Yesterday night before going to the bed, my phone battery was >80% charged. In the morning I found my phone switched off. I had to restart the phone using the power button. The battery was at about 40% down when I turned it on.
I dont use the phone much through out the day, so it uses around 20% in a day(morning to night).
There is nothing unusual that I can see in the battery usage stats. Attaching screen shots for reference.
The graph shows a sudden decrease in the battery power. I am not sure if any sofware can consume so much of power in such a short time, unless there is a hardware issue or the battery readings themselves are incorrect.
This is the third time in the last 5 days that I found my phone powered off in the morning with a sudden fall in battery power.
I am using the stock android 4.2.2 with all the updates applied.
Can anybody please help me understand whats going on?
When it drops straight down it signals either a reboot or a power off. Something is causing your phone to turn off (obviously), it isn't just a battery drain issue. That said, it shouldn't drop that much if it is off.

Thanks josh, is there a way to debug whats trigerring the shutdown? What worries me is the sudden power drop? Could this be a harware issue?
There might be some safety mechanism which will shutdown the phone in case it finds the battery current is extremely high. I am just guessing.

The battery % indicator isn't completely accurate so whenever you reboot your device it tends to show as a lower value than before you rebooted it. I find that whenever I reboot my device the instant drop is then offset by a slower than normal drain as shown by the indicator. Obviously the drain is no different but this is just what the indicator is showing.
I wouldn't worry about the drop itself so much, just what has caused the reboot. I can't help you there so maybe someone else has an idea on how to figure that out, good luck!
Try flashing the stock image again; efrant's guide in my signature is the best & most educational way to go about it..
P.S. overheating will shut the phone down. Maybe some rogue app misbehaving? Long shot but could be it. Search for betterbatterystats here in xda, see if some app produces some crazy wakelocks. If not, go back to the top..

You can monitor with betterbatterystats.
And if you are rooted you can check the root features in advanced settings to see any alarm that occur.
This will help you debug the problem.

I wouldnt be worried about the battery drain.. That is usual for your situation as you hardly use your phone, the battery reading isnt always accurate and is most accurate after a reboot.
If your reallt worried. Reflash stock images fromm Google. Don't use toolkits and learn something about fastboot and your phone.

Hey everyone,
I picked up a T2 on Thursday morning coming from a Maxx, and after the first day I felt I wasn't getting quite the battery life I should. After watching the battery stats and doing some research, the issue seems to be due to Lollipop's well-documented cell standby bug. Coming from KitKat I have been pretty frustrated by this, as my T2 will sometimes drain 5% or more in an hour of idling if WiFi (or possibly Bluetooth) is on, and seems to drain much faster with use if WiFi is on. (Note that all of this is taking place in areas with very strong 4g and WiFi signal).
When WiFi is turned on, Cell Standby tops the battery consumption chart by a large margin and my unscientific eyeball test suggests that the battery drains much faster.
Is anyone else having this issue? I'm considering taking the T2 back, but honestly there aren't any other new phones with comparable battery life, and it would be hard to give up the shatterproof display. Other than this I'm loving the phone and Lollipop.
Thanks!
I'm not having that issue at all and I leave my WiFi on pretty much all the time. I just checked mine and in 13 hrs my cell standby was 8%. Honestly idk if that's good or bad.
I guess I'll just keep an eye on it. Over this past night Cell Standby was on for 10 hours and had the Mobile Radio on for 8 hours while the phone was idle. Not sure if this is intended or not. My battery woes could just be in my head.
cell standby has been near or at the top of all 3 of my Verizon Lollipop phones so dont believe its a Turbo 2 direct issue.
I guess I'll just be patiently awaiting marshmallow then!
Try this, idk if it'll help or not but under WiFi settings under keep WiFi on during sleep, choose only when charging.

I've also read this cell standby time is related to WiFi and possible fixes are as follows. Turn off allow Google to scan for networks even if off, keep WiFi on during sleep charge only, LTE instead of global, and then go into recovery and clear cache. This is what I did and my cell drain is very low. Hope it helps.

Thanks for the tips - I changed all the settings but I'm having trouble getting into recover. When I try to launch from the bootloader I just get the dead Android with "No Command" displayed below it. Is there something I'm missing? FWIW I have dev mode on and unlock oem bootloader on.
I wouldn't turn on unlock boot loader this disables some security features and unless we have a way to truly unlock it. It's better to leave on. Dev mode doesn't affect drain issue at all. Here's link for booting into recovery.

Got it. Thanks for the help!
Mine drains fast while sleeping at home. In my case, the signal is poor so the phone has to crank up the radio power, draining the battery.
UPDATE: For anyone interested, the fixes suggested in this thread seem to have done the trick for me. After changing settings and wiping cache I am getting even better battery life (7-8 hours of screen on time up from 5-6 in similar conditions). This could, of course, be due to other factors - but hey, it's worth a shot if your battery is draining quickly!

I personally have noticed that turning off mobile data when connected to WiFi helps. I have done this with previous phones
I experienced this the other day after spending the weekend in an area with spotty service. To fix all I did was reboot the phone.
