[Q] No or Unknown Signal - Galaxy S II Q&A, Help & Troubleshooting

In BetterBatteryStats, under Other and Since unplugged, the no or unknown signal has been going on since the start of BetterBatteryStats. What does this mean? Is this draining any battery? I am getting perfect 3 bar signals.

I'm having the same issue as you, not only that it also has "No Data Connection" for the whole night make my phone can't go to deep sleep 100%.

Hey guys, have you found an answer for this yet? I'm also experiencing this, although I am using a different phone.

I wanna know too! Anyone?

It's just an issue with the app. Nothing to worry about.
But Remember: Task killers and battery stat apps drain battery charge

Thank you! Yeah I'll keep the app for maybe a couple more days for consistency then I will remove it. I don't use task killers but gemini to eliminate autostart, I might disable them all to see how it goes

[Q] Battery usage graph, screen off, awake?

Hi all
I was wondering why battery usage graph says phone has been once and while "awake" though "screen on" says it has been off?
What does that awake graph tell you actually? That S2 has been doing something behind the scenes or what?
I have the EXACT same issue but have yet to find a solution (though, I am on the Nexus S 4G)! I think this is what is causing me unnecessary battery drain since I am assuming that the blue bars associated with Screen On and Awake should correspond almost exactly.
While I know this post has not been helpful to you, I just wanted to tell you that you aren't alone. Hopefully someone will help us out soon.

same here, waiting for solution
A app has awoken the device from deep sleep, that's why it appears.
A phone can be awake while the screen is off. Some widgets may run/update in background. So its common, I don't see a problem in that.

Is there a way to check which app keeps the phone awake? I'm having this issue aswell, causing a battery drain sometimes.
same issue

Having the exact same issue with SGSII Litening ROM 2.2 on 2.3.4 KG1
Tried canceling Facebook&Twitter widgets and refresh rate
Disabled any dynamic widget
Disabled Live Wallpaper
Removed Skype
Removed TalkBox
and still no good, my phone wakes up for short intervals while screen is off and no use
must find a solution
I've had the same problem and was mad that what really kept running on background. But after I start using ATK it is almost gone. This is mine after 23 hours, before ATK it was a different story.

ATK didn't work out for me.. i used ATK Pro
I just found out that during idle(screen is off) the processes: 'suspend' and 'events/0' are waking the phone once in a while and using CPU
Does anybody know this type of problem?

I had the same problem and solved it.
I had the Location Services enabled. Disabled those and now it doesn't wake up when screen is off.
Hope it helps... It worked for me
Good Luck

Random power downs when not using. (CM9 ICS nightly)

I am getting some strange battery behaviour.
My device will turn itself fully off when sleeping about once a day. The power use graph often has strange jumps in it as well.
I've tried resetting battery stats but it's not made a difference.
Any ideas what could be causing it or how to fix it?
I've been having the same issue for the past few days. I've also been having a good amount of crashes. I am thinking about starting completely over: Odin back to 3.2, reinstalling CWM, and then trying the nightlies again. If that doesn't make it more stable, I may try Task 14 (HC).

Have you ever uv your device? It sounds like sleep of death.
And
If you're rooted download better battery stats from xda applications section and cpu spy from the play store to see your wakelocks and if your device is deep sleeping. Then post your bbs dump here

OK i've got both those apps installed now and it is deep sleeping. I'll let it run for a few days and post the bbs dump.
Thanks very much for your help.
OK I've attached my BBS dump.
Can anyone identify an issue?

Well first, I would not recommend Juice Defender. I have heard that it causes the batter to drain more.
Secondly, the stats are only for not even 3 hrs. If you want a proper reading of what is draining battery it needs to be longer, if possible.
EDIT: What rom/kernel are you running? And did you do a full wipe when you flashed them?

I need an app that turns the wi-fi off when i'm not using it as I find wi-fi being creates a big battery drain. JuiceDefender has served me well for that purpose for years. Any other apps you can recommend for automatically turning off the connections?

Unfortunately 3 hours was the longest I could get before it turned itself off and the stats were lost.

I was running CyanogenMod 9 Nightlies Galaxy Tab 10.1 WIFI, then after a week switched to [ICS]Ganbarou GT-P7500/7501/7510/7511 CM9, and I am now as of yesterday on [JB][AOSP][ALPHA] Android 4.1.1 - Jelly Bean - [GT-P7510], full wipe as usual for them all, bar JellyBean where I had to return to stock first.
I've had the same power problem on them all, but i've noticed i've managed a 10hr stretch on JellyBean, so stats are attached.
Problem fixed.
I installed the Jelly Bean alpha, but it was still happening, so I drained the battery completely, then charged it fully, and that fixed the problem.

10% battery drain overnight?!?!

I noticed my S3 drains about 10% battery overnight. I dont think this is normal. Wifi and 3g are off, it just lies there by my bed doing nothing. Ive restarted it and no help.
Cell standby shows 41% usage. Is that right?
The 2 red circles in the screenshot show when my phone is idle just lying there.
Any help?
We need more information. What apps run? have you remove/freeze bloatware. Are you rooted? what rom are you on?
I'm going to run this based on speculation perhaps side effects of rooting your phone? I know there is no conclusive evidence of this but a hypothesis as such. My apologies if you aren't rooted.

why would rooting your phone create battery drain?
OP the standard answer is to install better battery stats and check it again to see what those wakelocks are. Once you find out why your phone is waking up you can do something about it.

I'm also getting a 10% battery drain over night. I've been putting the phone in airplane mode to see if that helps at all but it really doesn't. Anyway we can inprove this? 10% seems like a lot for sleeping...

install better battery stats and find what causes wakelocks......as above post!
Sent from my GT-I9300 using xda premium
thanks for the replies everyone, Im using the latest stock firmware... no rooting here...
Installing better battery stats as we speak and see what they say...
GSam Battery Monitor and / or BetterBatteryStats would be the first place as mentioned already.
I was able to find what was causing me most issues. It was some Calender storage and Google syncs (bookmarks, contacts etc) even though I didn't have them activated.
Anyway, after freezing them I now only lose 2-3% overnight. That is with gmail push, email sync every 4 hours and about 7 or 8 other Widgets updating every few hours. Mostly noticed a massive improvement when I flashed the latest siyah kernal.

I don't know but I get the feeling that rooting various phones might have hidden side effects as such, rooting your phone is still evolving as of today. There are still alot that the general doesn't know hence there are always new things about rooting although I might not be knowledgeable in that department. However is it possible to unroot your phone? rather revert it to stock? try doing that and see if there are any differences.

S3 Battery Drain

Hi guys,
I've been experimenting with my newly bought S3.
Installed custom rom ARHD 10.0 to be specific
Installed betterbatterystats, titanium backup and setCPU.
I suppose most S3 users get a decent battery life. I noticed in some threads some users even got 1 % battery drain while asleep!
I have attached my logs. Could someone proficient in reading explain whats wrong with my battery life?

How could this be in it, my battery life is also quite long no leakage thing ah

I'm not too sure why. Probably i should do a super wipe (for the 3rd time)
Facebook is the one who's draining the battery

Thank you for that. Do i disable facebook totally?
^no need to disable the app. just disable the notification or set the "refresh interval" to like every 1 or 2 hours. setting it to "never" will not drain your battery

High battery drain when Idle

Anyone else experiencing this?
My old one is fine but the replacement is loosing battery very quickly. It went 100% to 80% sitting idle in just 5h with no background apps running.
I tried reboot and cache wipe. Also tried disabling apps. Still draining quick.

Nope not installed. I even tried factory reset and disabling preinstalled oculus services.
I don't get it. Few days ago the battery was phenomenal. I seriously got well over 8h sot. Now it's draining away noticeable faster.

Hi.
U might want to install BBS to check for any offending apps/settings that might drain yr battery.
Mine is actually opposite. My old one had a severe battery drain overnight (around 15-20%) but my new one only drains like 7%
Never understood why but my guess is the battery itself
Could it be a LTE, Wi-Fi, Bluetooth or other issue? Where I'm located my LTE signal varies and I tend to notice a difference in the battery life.

Not sure what happened but the battery drain is better now. I didn't change anything so not sure. Maybe it had something to do with the signal / radio.

I Agree with you:good:
I get 10% drain in about 7.5 hours when attached to Wi-Fi.

I read in other posts that chrome may as well be a battery drain
You can't get stable battery result all the time with Android, esp Samsung. Normally my Note7 perform good but somedays it is quite bad
