Hello all,
I bought my iconia tab last Tues. I am a big fan of android. But I have used an I pad since they were released. Now I'm not going to make comparisons, but I'm thinking I may have received a bad unit. Or maybeothers can verify my findings.
Battery life is horrible.
I barely get 4 hours of use before I need to go running for the charger.
Random shutdowns and reboot.
Unit will shutdown at random, even when I'm using it. And it reboot any time it loses a wifi source. Ex. I have a mobile hotspot. If I shut the hotspot off, the iconia will reboot when it loses the signal.
Screen on/off all day.
When I put the unit in standby, the screen turns on and off about evey 2 minutes.
Laggy keyboard.
Even as I type this, the keyboard is extremly laggy.
I am running this unit stock now, nothing extra has been installed.
I even did a factory reset and hard reset.
Ii have not received any updates, although I check all the time. I'm still on the 1.104. Build.
Any suggestions? Thanks.
from your description, yeah, you should probably return this unit...
just return my device is not that bad, battery last 1 day with normal use, never random shut down
the only thing i got troubled with is screen on/off , that is solved by pressing powerr button several times, very annoying actuallly
I've gotten 2 days of moderate use, I usually charge every night but unless I'm playing games for hours at a time I'm usually @ 40% before I plug in.
If the tab is rebooting on a frequent basis, particularly if you can do it on demand, definitely return it.
The screen random on should be fixed by the .141 update
I don't want to start anything but when i read "Should I return it?" and your posting it in this forum, then most likely the person posting it (if you found this forum) knows a little about it. But to read, it shuts off, battery life is terrible, etc..
I dont use it all day but i will use it with lowest brightness, 1 min timeout, and i dont use twitter or play movies, but get like 5-8 days on a charge.. NOW, one key thing, i turn the power OFF when done using it and does hold the battery much better (I never tried airplane mode)..
Never mind, got off on a rant from the thread...unrelated, there are some very cool news apps that are out now for HC.
Ok. Returned it for a fresh unit. Letting it get a full charge before I do anything with it.
Fyi. Previous unit only gave me 4 hours. Regardless if I was using it or it was sitting in standby.
Does anyone know of a way to get the 141 update without rooting?

For the first time since I bought it I haven't used my device for a day. In around 22 hours of standby it lost 3% battery.
So draining in 4 hours in standby sounds completly defective to me.
when I got mine
battery was at 50%
I used it during the day, and when the battery was arround 5% I did a full charge
- regular usage : 1day ++
- working usage : 8 hours (web apps dev...)
4 hours, use it or not it's awfull...
Wish you got better now

What kind of screen problem? Is it turning on randomly while in stand by or the other way around, turning off while in use?
And for my future reference, how do you do returns in Indonesia? Do you take it to the store or to the service center (or either)? Thanks in advance!

Yes, the screen would randomy turn on/off while in standby.
The other. The tablet would actually power off while i was using it, not just th screen, the entire thing.

its turning on randomly while standby, usually i have to pres power button 3 or 4 times before it went off without turning on again...
i think its not possible to return to the store here, just take to the service centre... but i dont know if they will give new device.. as i know here only apple , blackberry and samsung that will give new device if found defective ..
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."
So, yesterday I noticed a sudden battery drain on my nexus 4. After checking battery it showed that AndroidOS takes over about 50% of the battery usage. It also showed that time awake was pretty much the same as the amount of time since I unplugged the phone, even though I kept my phone in sleep mode for the most of the day. After some research I downloaded better battery stats and it showed that from the moment I turn the screen off a process called suspend_backoff runs pretty much the entire time. Eventually I got it down to wifi. If I turn off wifi there are no processes running after the screen is turned off (or if there are they are 30 seconds tops), but the moment I turn wifi on suspend_backoff runs pretty much the entire time screen is off. I tried removing all of my apps, as well as doing factory reset but nothing helps. The moment I turn wifi ON this suspend_backoff consumes pretty much all the time during screen off period. Is anyone experiencing anything like this ? I have 4.2.2 on the phone and I havent' seen this extreme drain until just yesterday.
I experience the samething. Android OS would drain as much as the screen time.
I narrowed it down to the suspend_backoff. But the weird thing is that when i'm at home on my home wifi, suspend_backoff doesn't seem to drain anything at all. But when I'm at school, suspend_backoff kicks in.
Anyone help?

how did you narrow it down? Im having the same problem!
This is caused by a kernel wakelock. A bad mobile connection make battery drain worse... using WLAN nearly fixes this problem.
Thought this problem has got fixed in 4.2.2, at least battery life got improved and the wakelock reduced.
If it is appearing since yesterday, it is triggered by a app often waking the phone up using mobile data (that's why fixed with WLAN) and prevent the phone from getting into deep sleep as fast as it should.
hope i could help.
I use Greenify to hibernate every single user installed apps, then I release them one by one to see which one cause suspend backoff. But suspend backoff still occurs. So I think it's the kernel itself.

Yeah, definitely not user apps. I did full reset on the phone to factory settings, no user apps. Even tried disabling Google Play and Google store after the reset. Still the same. The only thing that gets rid of it is disabling WiFi.

Yeah, it's clear that it's the wakelock. What's not clear is why. Also it's not the msm_hsic_host that the forum link you sent refers to. I don't have a problem with msm_hsic, that one barely takes any time during the day (maybe 30 seconds during several hours of standby). The wakelock causing this particular issue is "suspend_backoff" wakelock which supposedly happens when there is a sequence of sleep/wake calls too close together so the system decides to keep it awake. I was unable to find what exactly is causing the issue, even after restoring to the factory settings I kept seeing the same problem.
Anyway, I was able to "resolve" it by installing JuiceGuard app and setting it so it disables wifi when the screen is off. wakelock is gone now and my battery usage is back to normal.
I only get the suspend backoff wake lock when I'm connected to the university Wifi. When I'm at home, everything is fine, no suspend backoff. So my guess is that the Wifi encryption at university is different and causing a succession of close "awake" and cause wake lock.
I did factory reset like 3 times and it still there.
I'll try disable Wifi on Monday and see how it goes.
Same here, when wifi disabled the wakelock doesn't occur.
I have tried almost all of the kernels and non of them seem to help.

Interesting... Maybe it is encryption. One thing with my Wifi is that it doesn't use password, but MAC list instead. It may indeed be an issue with different wifi encryption types.
OP do you have maps 6.14 on your phone? Mine kept switching on location reporting for a while and it woke my phone 344 times last night. I've been struggling with the same wake lock issues. I'm going to recharge (again) with maps disabled and see if that helps.

Check your Google account sync settings... In settings
The clowns may have left you a lovely gift there without telling you or asking any kind of permission.
The latest Maps was giving me horrible battery drain, on WiFi. I'd sleep for six hours with a fully charged phone and wake up with 10% left. it even enabled itself when. I disabled it in settings. I converted it to a user app by moving it to /data/app and greenified it. Seemed to have solved all of my issues with the suspend back off wake lock.

I installed on my oppo 5 pure AOSP, which i didn't like so I have decided to move to MIUI.
after moving to MIUI my phone started turning off by itself (screen goes black) and the only way to turn it back on is to connect it to a charger.
So i moved back to stable stock rom and still, moved to stock beta phone crashes.
thank I noticed that the crashes happens whenever the phone is connected to the WIFI or the mobile network data.
if both are off the phone is working steady, but the moment i put any of them on the phone crashes.
BTW it is only mobile network data, phone calls are still working without crashing the phone.
I need help!!!
edit #1: i installed cm10.1 and it doesn't crash when connected to WIFI, but mobile network doesn't work at all (no signal)
edit #2: even when i am doing a proper shutdown to the phone, i cannot power it on unless i connect it to the charger, battery is show more than %50

If you have a second phone like me, try to use airplane mode then WiFi. If it still occurs then it is probably hardware.

OK, Cool.I need a full discharge log and a charge log (till battery hits 100% again).
Is this with airplane mode on?
the phone battery was draining quicker than before and after 11 hours of low usage, but the upside is that it was behaving fine during these hours. at the 11th hour the phone suddenly died while it was at %21.
now I am charging the phone while it is off until it will reach %100 and i will power it on and upload the logs.
I did not had a secondary phone at the time so i was still using it (well, I was visiting my family so I was eager to show off my new phone )

the no signal problem is a issue that appears on Cm10 and some other roms based on Cm you gotta reboot your device some times until the radio wakes up. the other problem , try to install Aospa ( paranoid android ) and wipe everything wipe factory and system also wipe dalvik cache and cache. install zip and Gapps ( or do the same method but install STOCK , u can find stock firmwareon the oppoforums )
Under kernel wakelocks in better battery stats. Is anyone getting the mmc0:0001:2 wakelock? It has some serious counts an I think it's a culprit of some deep sleep issues. I tried with factory reset and not restoring anything, just installing bbs and its still there. I'm attaching a pic of insane 1.9 million counts. Anyone got any idea what this is?
EDIT: okay, so I did notice it was ticking like insane when I was downloading some games. And figured I would try turning off Wi-Fi, look and behold, it stopped ticking. Even when I turned it back on it back on it didn't tick up either. But if I turned if screen and later checked it was ticking again. My router had been acting weird lately so I made it forget it and put up a hot spot on my other phone. Now it doesn't tick up either, so must be my router D-Link DIR-655 with latest firmware. Good thing in getting a new router next week. Will update if it's better (going to buy a DIR-865L). Please do report if you are having same problem and find other solution though.
EDIT2: I left it using hot spot and awake time went up like 2 min and deep sleep 1.5 hours. Now it sleeps like a baby. Will update with new router next week. Hope this helps someone.
EDIT3: After a restart it started ticking up again for some reason even when connected to hot spot.

Galaxy Note 3 here. I'm getting the same thing, it's causing my phone to stay awake 100% of the time. I turned off my wifi and now the problem is done, but that is a huge hassle as I want to be connected to wifi all day if possible.
Will see if it's a router/modem issue or if it's a wifi on the phone issue.

Okay so, kinda forgot to update this thread, forgive me, Im a human I got my new router DIR-865L and I keep getting the same wakelock, however, this doesnt seem to make my phone to wake anymore, so I guess it was my old router, DIR-655 that gave the wakelocks. If you can try with a new router or at least another.
My Galaxy S4 LTE-A has the same problem. It occurs only when I connected to wifi.
Mmc0:0001:2 seems related to sd card, so I removed my external sd card.. but it did no trick.
And it is thought to lead to battery drain.
When connected wifi, battery decreases about 3% per hour, which is nearly three times to LTE.

Any updates/solutions? I have the same problem, it started after i rooted my LG G2. Unrooting/changing firmware/factroy reset or changing my router gave no effect

Anyone has any solution for it?

I have the same thing now, wakelock detector app is showing it running hundreds of thousands of times with the phone only on for a few hours.
