When I look at my battery usage I saw that my S2 is constantly awake, even when I turn the screen off and put the phone away for a couple of hours.
I've turned off Wifi/3G and even background sync, but it stays awake all the time causing the battery to drain a lot faster than I want. Is there a way to stop this?
I hear people talking about theirs dropping only a couple percent per hour when not using the phone but mine at least drains 10% per hour.
Could it be the Social Hub?
Btw, my S2 runs on the latest KE2 firmware.
For me, I've noticed a big decrease in idle-battery draining when I rooted and removed Social Hub and I never even used it. It still stays "awake" as much as it did before on the little lines in the battery usage app, but a lot more juice.
Used to lose 10% per hour like you, now more like 5%.
If it stays awake all the time, something is _wrong_. If I don't use my phone the only awake time I can see in the battery status is every 15 mins (approx) when it goes "awake" a couple of seconds to update all the **** I have updating. It never stays awake all the time.
edit:
And just to give some more info. Mine is still stock on KE2 with all the crap Samsung put in the phone still in place.

sorry for highjacking your thread, but how do you guys get all this awake battery time info, is there a particular app you guys use.?

I think I experienced the same thing this night. I lost about 10% in 7 hours but the graph still showed that my phone was awake all the time.
Again, I turned the Wifi and 3G off. I'm still running the stock KE2 firmware together with all the Samsung apps. I haven't rooted it yet.
Also, Maps and Social Hub seemed to be active a lot when I look at their stay awake times.
bump.
to much awake time here as well.
how can i find out whats causing it?
I'd put money on it being widgets. Remove all the widgets from home screens, restart the phone and see if that fixes it. You can thank me later ;-)

I have this problem from time to time, killing wifi sharing stopped it for me. Comes back once a day for no reason I can see. 1 Kill a day keeps the phone last a full day for me.

Yeah I also see the occasional WTF moment when the phone suddenly decides in the middle of the day to stay awake 100% of the time. Battery then drains about the same 5-10% an hour you see. Not sure what causes it but a reboot usually fixes it, battery drain goes back to 0.5%-2% an hour that it usually sits at.
Sometimes I also see wifi sharing eating a constant ~50% of CPU, at which point battery drains more like 25% an hour, though not sure if it's related. If only I could disable the damn thing without rooting.
I also have this weird problem. My 2g data connection remains on because I receive a lot of emails so Ive enabled push notifications. However the problem is even when the screen is off, the phone stays awake 100% of the time.
I went to sleep after completely charging the phone at around 11pm and when I woke up at around 9 am, the battery was at 30%. That is 70% battery gone for not doing anything at all. Really need a solution for this guys. Or should I just turn off my data connection?
i had this prob with Widgetsoid installed.
Problem gone when i removed it.
Find on XDA BetterBatteryStats app.. Use phone for a while then run app. Check detected wakelocks. Based on that you can hunt which app or widget keep device always on.
Phone works normally if you compare Screen On and Awake graphs. Both graphs should match. Awake periods can be sometimes be out of screen-on intervals, but no too often.
In my case, I found that maps keep my phone awake.. then I figired that weather widget kep tracking my location (and uses maps for this). Also Lattitude uses maps to track location. When I configure weather widget to not track my location (im usually always in a home town) and turn off latitude, lots of awake periods dissaperar.
I've got the 16gb nexus 7 (non 3g).
I've had it for less then a year and the battery life had been great. But starting over the last few days the battery is horrible. After a full charge over night my battery was down to 50% today. And that's with hardly any use. I used it for maybe an hour total and at least half of that time was just reading reddit.
I haven't changed any settings recently. This is all stock, no mods, not even rooted.
The battery usage right new says it's been 13 hours, and it's down to 48% and Android os accounts for 27% Followed by screen at 18% and WiFi at 9%. Those are the top 3 showing for battery usage.
Any suggestions as to what's going wrong it how to diagnose be fix it?
Thanks
Either your battery is bad or you have a stray process running somewhere.You might want to factory reset it, possibly even reflash your image.

Would the battery go bad that fast though? In my experience batteries usually gradually get worse. This went from losing a few percent of power to losing half power in the span of a day.
I might try the factory reset - just have to make sure everything is backed up. This tablet isn't rooted so i dont have titanium backup on it.

Doubtful it's the battery... my money is on a rogue app!!!
Hi, merkk...
It's possible, that as the previous poster suggests, some rogue app is 'eating' your battery.
The biggest consumer of power is the screen, so ensure you haven't got it set it maximum brightness... and ensure auto-brightness is enabled in settings.
Another thing you can check, is your WiFi setting... on my Nexus 7, I have 'Keep WiFi on during Sleep' set to 'Never'... it's not a setting that is easily found - it's buried in SETTINGS>>Wi-Fi>>overflow MENU (three dots, top right hand corner)>>ADVANCED>>Keep WiFi on during Sleep.
It also might be worth checking if the SYNCING of your respective accounts (Google, Twitter, etc.), haven't been inadvertently changed. Particularly the SYNCING of your Google account... which by default, SYNCs a lot of stuff and frequently. This will keep WiFi awake, and may cause battery drain. Go to SETTINGS>>ACCOUNTS>>GOOGLE and disable what you don't need to be SYNCed.
-----------------------------------------------------------------------------
It's unfortunate that your Nexus 7 isn't rooted, because there are a couple of excellent diagnostic apps available (GSam Battery Monitor and BetterBatteryStats) which provide more granular and finely detailed battery info/history than the standard Android battery info screen... and are useful for tracking down problematic apps that might be keeping the device unnecessarily awake ('wakelocks', etc.).
However, due to changes in Android 4.4 (KitKat), these apps now require root access to read and report battery stats info.
If your Nexus 7 is running any version of Android BEFORE 4.4 KitKat (and some haven't updated yet), then you don't need root to run these diagnostic apps.
-----------------------------------------------------------------------------
It's sometimes the case, with Android, that there will be occasional peculiarities with battery performance... and in my experience, it's almost always the case, it's due to something the user did... some app or widget installed. I'm currently experiencing similar battery issues on my Samsung Galaxy S3, but having run GSam for a couple of days, I think I have the culprit identified. If I can't eliminate the problem, I'll uninstall the app.
-----------------------------------------------------------------------------
Hope my ruminations are of some use.
Rgrds,
Ged.
Gedblake, thanks for the suggestions. For whatever reason, today it seems to be back to normal. The only thing i did last night was drain the batter to around 10%, turn it off, and let it charge while turned off.
Turned it back on today,used it for about 15 minutes or so playing a game. And now just about 5 hours after turning it on, it's down to 92% which is what I'd normally expect.
I'll try some of your suggestions if the problem re-occurs.
I noticed that my N7 (2012) has been draining quite a bit lately. Watching the battery stats, it seems Google Wallet was eating up some major battery. It was 2nd at 29% with the screen number 1 at 38%.
Not sure what the heck Google Wallet was doing, but I killed it and things seem to have stabilized.
battery drain after update?
For years I've had the same routine. I use my Nexus 7 all day for work, mostly notes. In between I play, (youtube, E-reader, etc). Every night I plug it in to charge and in the morning it's fully charged and ready to go. On Tues, I received the OTA update for 4.4.4 I noticed this morning that after a full night's charge, the battery only reports 50% charge. Is this the beginning of the end? What steps should I take from here? I recently bricked by GS3 so I depend on this thing now more then ever, any help would be sooooo appreciated.

I'd just restart it and let it charge again. I've updated mine a while ago and haven't had any issues.

I'm on a custom 4.4.2 ROM and I have had intermittent draining behavior as well.
Sync is off, location services off, I turn off wifi manually, and I always clear recents before I have my tablet sleep. I have greenify installed. I'm using better battery stats.
My issue seems to be similar, but I am also having battery percentages jump around.
Earlier today it went from 26% to 43% in the middle of me using it. Without charging. It frequently does this, both lesser and greater values reported. I've had my tablet shut down in the 30% range. I've had it shut itself off on 4%. I've had it drain all the way to 0% and then some before shutting down. I've had it turn itself off and when I power it back on the tablet is thinking it is at 25% or more.
I haven't been getting much more than an hour of screen time with my tablet lately. Clean fresh install of my ROM.
But I've never, until the last couple of days, had it go from a small percent to a large percent active during use. I took screenshots. I even started a thread to talk about it but nobody has responded yet.
Has anyone else ran into this behavior? Is it a sign of a soon to be dead battery?
mine got almost 30% drained on idle, airplane mode, screen off for 3 hours (tested on stock rom 4.4.3. GApps + Swiftkey + BBM + Facebook only)
my nexus 7 never lasted a day, only half a day max.
trying GSam app, hope it helps in knowing what's eating up batteries.
Hello everyone,
Since my S4 is on 4.4.2, it's always awake when the screen is on, even if I'm not using any apps, which wasn't the case before the update. I'm rooted and used BetterBatteryStats, but I can't find any processes or wakelocks causing it. Screen-on time is pretty bad. Does anyone have an idea how to fix this?
Factory reset didn't help.
Thanks!
Come on...Is this really the skill level of XDA now?
If your screen is on, then your phone is awake. How should it display anything on the screen while your phone is sleeping?
Your screen on time is perfectly normal.
Be easy man I saw this problem few times, he is talking right but I dont have a solution

No, awake means the phone is actively doing something. Before the update, I've browsed websites for hours without the phone being awake at all.
For example, the stats of a GSG4 Mini on 4.3:

No you didn't.
The battery stats screen might have been saying that, but it was a reporting error by the stats monitor. You absolutely positively under no circumstances were browsing the web without the phone being awake.
Also your battery stats screens are not showing that the screen is on constantly. It's showing that your WIFI is on constantly.
I don't think WIFI is the problem here. With the screenshots I just wanted to show that the phone is awake (and using relatively much power) as soon as the screen is turned on, and doesn't stop until it's off. On the mini/before the update the phone wasn't constantly awake while the screen was on, as shown in the previous screenshot.
Any ideas how to stop it? Or is this just a quirk of KitKat? I'd be glad if someone could check their battery stats on their device.

Dude, your other phone was awake when the screen was on. Period.
All phones are awake when the screen it on. Period.
It doesn't matter what battery stats or monitors say. If they said the phone was asleep while the screen was on and while you were actively using it, the stats were wrong.
If the screen is on, the phone is awake and the processor is processing stuff. There is no grey area here. There is no possible way a phone's screen it on and its displaying an image without the processor being awake and active. It's physically impossible.
Hi, new owner of DT2 after returning my galaxy7 edge. I'm having an issue with wake lock. When I don't use the phone for an hour or so, and haven't touched it, my battery barely loses anything and the wake time under the battery setting reflects that. But when I'm casually using it - sometimes using it for two or three mins, then not for 29-30, my phone seems to stay awake a lot when the screen isn't on. I thought this could be a rogue app, so I'm running it in Safe Mode, but I still see the same trend. Does Moto active display cause the phone to wake every time it reads motion?
Attaching screenshots. The battery charts are when I had it in Safe Mode. The gsam readout was in regular mode. Based on how active the phone was, I would've barely gotten 2 hrs of SOT
Hi. Generally, Doze, the feature that allows your phone to barely sip power when your phone is not in use, will not kick in until around an hour. Yes, Moto display will wake the display every time it thinks you are trying to use the phone but it should still use only a tiny amount of power. Also, don't put too much stock into the projected battery chart. Sometimes, it is very conservative and other times, it is wildly exaggerating. Hope this helps.
I did a factory reset on my phone and left the phone sitting for about an hour. The awake time was still represented about 30-40% of time on. My phone has been getting about 2-3 hours of SOT over the course of a 12 hour day. Seems like the awake time is really eating the battery. I wonder if others are having this issue. I didn't have the phone before the Marshmallow update, so don't know if that's the culprit.
I have noticed then when I keep the phone aside overnight.. idle condition (wifi off, location off, data off) and go to sleep.. I wake up with a drop of 8-7% drop in battery, is it normal? Because none of my previous phones showed such a drop in battery. Anyone else facing the same issue?
My battery life had previously been fine. We had that last security update from AT&T and suddenly, my device is awake almost 100% of the time. Android OS is always at the top of my stats and awake time shows at 99%. I used the light version of Wakelock Detector (which doesn't require root) and it's not really showing anything, but I deleted all apps showing the most wakelocks anyway and I'm still at 99% wake time. I even took out my SD card to test that and it hasn't changed anything. I also disabled GPS to test and "awake time" still stayed at max.
I'm on the verge of wiping it, but I have already done that once to resolve other issues and I know there has to be a cause to all of this. Is anyone else experiencing this since the last update? Anything I haven't tried that someone recommends? I have not installed any new apps or anything.
One thing to note is that my drain is only around 1%/hr at idle, but I'm pretty sure the phone still shouldn't be awake almost 100% of the time.
1%/hr drain while idle means 4 days of standby i think you're fine

That doesn't change the fact that the phone is awake over 99% of the time. After a wipe, it's no longer going that and my idle drain is less. So, something was clearly wrong.

Yeah, you're right if the behavior is different after resetting the phone. I was wondering if maybe Wakelock Detector might see certain features of the QC820 like AOD as applying a wakelock.
