So I know there are several threads on this, some by me, but this time the issue is very weird.
So i'm on my third phone now, previous 2 had the USB port going wacky. Phone thinking it was charging when it wasn't plugged in, computer not recognizing phone anymore etc.
So problem has now started again on phone number three. Weird thing is this time the phone seems to not have this problem all day. Problem starts at night, so i'm assuming maybe a battery percentage left triggers it. The other weird aspect of this is that right before the phone starts bugging out, (charging, uncharging, and back, over and over while not plugged in), the car mode symbol appears in the status bar, and starts flashing on and off. If I am fast enough to catch it,I can deactivate car mode. When all this starts happening, phone also starts to get stuck and freezes up. This issue is really getting annoying. Love this phone but this is starting to make me crazy. Yes I got the phones at different stores. What do I uninstall to just get rid of car mode, considering I never use it?

So, instead of using your existing thread, you decided to start yet another one for the same issue? And people wonder why the search doesn't work like it should.
good old miami son taking time out of his non existent life to not give any helpful info, but just to be a wanna be moderator. You were obnoxious and annoying in the captivate forums and I see you picked right up over here. Boy am I excited you got a new phone. Anyone else have any helpful advice?

Seems to be whatever USB cable you are using or the way you carry this phone is the problem. No way you get 3 phones the same exact problem in a row. FYI, Samsung Focus and Captivate had the similar problem in the past. Car mode is just the result of your USB port problem instead of the cause of it. What happens is something shorted out or bridged the pins of the USB port to make the phone think it is conneted to a car dock (IIRC, car dock uses a 300k resistor to bridge two pins). Some ppl with Focus or Captivate reported success by blowing out the dirt in the USB port.
As well as cleaning the USB port with an alcohol swab

The only USB cable I've used with all of them is the one they come with. I've used the alcohol cleaning method as well as blowing in the port, hopefully getting out any thing causing issue. This seems to help temporarily. The strangest part of all this to me is with this latest phone, I have zero problems all day. When I lay down in bed for the night and start using the phone is when it starts to happen. My battery life can range from 60%-30% at that time, so I don't know if that is a connection to this issue. Maybe the phone is possessed. It always seems to take about 2-3 weeks for this problem to arise. I always have the phone in my pocket, so I guess something must be happening with that. Luckily with this latest one, I bought the best buy insurance, it's just after awhile they're gonna start wondering why this keeps happening to me, and if it's my fault. The USB port problems can sometimes make it difficult/impossible to flash back to stock.

To the OP. The likelihood of that many bad phones in a row with the exact same problem is pretty rare. Take a look at anything that's remained consistent through all the phones, and try replacing that item(s).

+1 for replacing the cord and power brick. Alot less quality is put into them compared to the phone. Just make sure not to buy cheap. And never plug your phone into anything cheap (i.e. car radio usb port, off brand charger, ect) That's not saying everything else is bad. But why risk it. Especially when you can buy brand name chargers off ebay for $5 or less.

I've only used the supplied USB cord, every time. Now even when my phone isn't confused if it's charging or not, the battery life is now awful. 5-6% per hour drain. Used to be 1-2%. No changes made by me. Also the phone has become super laggy at times. Feel like i'm using my cappy again. My apologies for starting this post. I knew I would most likely get crap for it, but my issue is very strange, IMO, compared to mine and others previous experiences. I also figured if I added to an old post, it would go unnoticed.

If he is getting 5% per hour drain at idle, yes that is horrible battery life. SGS2 is fairly easily capable of 1% per hour idle drain.

i had this same problem. it wasnt with the port but it was with the usb cables i was using. but those cables would charge the phone fine but not allow it to get a connection with the computer. swapped cables and works fine.

You've used the same cord with all 3? or a new cord with each one?
It sounds like you've got a boatload of issues going on. Personally i'd do a wipe and try a fresh install without installing any additional stuff to be sure the hardware is fine.. Once you've verified that start adding apps to see if it was a specific one causing the issue. (there's other ways to troubleshoot this, but a fresh wipe is the most straight forward and simple IMO)

i suppose.
However he said before it was 1-2 percent an hour. That's pretty much impossible while being used, only get numbers like that while not in use (idle). Even %5 an hour while being used isn't likely to happen. Guess i just figured it had to be in ref to idle drain.
lol guess we just wait to see

I make it short:
Yeah another wifi/ battery thread. But the only one with an actual solution for pi poor battery life after 21 update. Some people reported it helped also with the sod.
Wifi sucks battery dead.
Some people let all sorts of juice sucking bat-control apps running to find out that stock app reading is not lying: The bloody wifi never turns off even set to do so in the settings and just kills the battery of the device.
If this is your workaround you owe me a thanks . If you are an Asus employee testing poor battery issue give me credits in the fixing OTA by repairing the 'never' settings:
Go to
settings, w-lan,advanced (click on the three dots in the upper right corner, there it is), keep_wifi_on_during_sleep:
Instead of setting it to 'never', set it to 'only when plugged in'.
Now put your machine in sleep, wake it after 30min or even much less and BOOOOOOM! here we go:
You will see in the battery settings, that your wifi just has stopped pausing. Depending on how long ago the battery cycle has started you will see two shorter bricks instead of a long one as before. While waking your machine concentrate on the battery icon and you will notice the wifi-icon popping up just a second after you have woken the screen.
Of course this works also with shorter breaks but I'm not sure what is the shortest interval. Longer sleep period opens the gap in between two wifi-sessions wider. So this makes the working proof easier visible for the eye.
Sort of really a shame that Asus, Google and Nvidia have hybrid, wrongly programmed and even forgotten settings in their setup. (see my thread about the multitasking of the HTC1X http://forum.xda-developers.com/showthread.php?t=1599214 Maybe helps your multitasking issue.
But as we know, nobody is perfect .... except for xda!!
And then, many report, they don't have this problem at all. Very strange that not everybody is affected by this blind setting.
If this solution doesn't help your device,I am sorry for you. Maybe you have to stick to the bat-control app and learn how to read it, or RMA your device.
Did the job for me.
So I am ready for summer to join in, got enough juice for the IPS+ screen to stun the sun the whole day lun . Rock'n Roll
Edit 121002:
JellyBeans workaround as well.
Edit 120616:
Thank you Asus that the .28 firmware makes my workaround obsolet. Now get rid of this arm5 coding and let the bugger run !!
Edit 2:
Title changed from 'Asus you owe me a blowjob' to something less attractive for trolls.
Should be an obvious solution for everyone. But took me a hell of time to use the next best (second) obvious setting for my w-lan and get the battery saving.
Edit:
Please don't abuse my thread to flame, blame or mob your boss, retailer, dog or whomever. Only confirmation or non-confirmations welcome. If you find another or better or additional solution in the future or the past please feel free to post it. I did not have the time yet to check for the actual amount of powersafe but regarding my normal readings we are gaining the whole lost lot back and don't need to throttle down or ruin our eyes. I reckon the bat is gonna be better because now some of the ASUS optimisation hits some ground.
If you want me to fled off, I have stolen your ideas or you are an ASUS employee with no job-offer, don't PM me.
Thanks
I have been using this setting for a while and while I do get better battery life using the "when plugged in" setting than the newer "disconnect during sleep" setting, in general battery life is still worse in .21 than in previous builds and for me WiFi alone still accounts for more than 60% of my average battery usage according to the battery settings menu. For all of my other Android devices the screen is the largest single user of battery.
It does not happen to everyone. I have it on "never" and as soon as i click the power button, wifi turns off... if i wake the tablet right away (2 or 3 seconds later), i see the wifi reappearing and reconecting. So, for me, the wifi turns off instantly.
In the battery graph my wifi line is nonexistant whenever the tablet is sleeping.
I believe the wifi options are implemented correctly (sort of). But for some reason, it doesnt seem to work for some users.
Another way to save battery is to increase the wifi scanning interval... but that is for when you are using wifi.
I guess, for those experiencing the battery drain, it may be a good temporary workaround to use the solution mentioned by the OP.

another way to MAKE SURE you save battery is turn the darn thing off and shutdown and then when you need it's ready to go. I been doing this more recently and it defeats the purpose of tablet, but hey, when i need to use it, after the boot up its on. not trying to be funny.
Let's not get carried away. While a good suggestion it's far from a real solution for all the people that are encountering this issue. It's kind of like suggesting just turning off your tablet when your not using it to prevent battery drain.

Auto flight mode
I always install an auto flight mode program that will turn off the wifi when the screen turns off since most widgets prevents the system from turning it off and going into deep sleep.

Your way takes far too much time for me to act spontaneous. With my changed settings it's doing it automatically again, just as was intended the 'never' setting. Unless you charge the tablet by cord, the wifi turns off while you put the tablet asleep. I say settings are messed up.

ill be the first one to Thank the OP as no one has. At least he is trying to help and find a solution. Even if it was something already known for the longest time. Sorry if the humor wasn't funny to you. Maybe he didn't know people already knew about this. which is totally fair.
to the OP, have you noticed that when you put wifi to stay on only when plugged in, when in sleep, that it takes a little while for wifi to come back online? meaning if you use the setting you said, then put the prime to sleep unplugged, then wake it back up, wifi doesn't connect back immediately. it takes a few seconds to come back online. that's the only thing I personally don't like about it.

yeah but personally this means to me it's working correctly. For the wifi to come back on instantly it would have to keep a connection and just not transfer data, when in deep sleep it completely turns off the wifi radio. When you wake it back up the radio turns back on, and it needs to connect to the AP all over again. This means the wifi was in a deep sleep (actually turned off the tab is in deep sleep) and it is working correctly.
I really wonder why every thread in this forum sooner or later becomes a trolling/flaming thread....
So guys, as usual (*sigh*) please stay on topic.
Trolling and flaming won't be tolerated but will be rewarded by other gifts like infractions and bans.
@OP: You might think about stoping posting in red: It usually implies a high rate of aggressivity towards other members.
Even if this might not be actually true in your case, other members still might missunderstand you.
On topic: This "fix" is really known since like, dunno, Froyo times? At least this setting is there already for ages.
Apart from that it should be obvious that turning off the Wifi drains less power.
However, you had good intentions so don't destroy them by flaming other members.
If you feel attacked by any post, just report it (obviously this goes for all members)
Thanks for clearing up, Diamondback,
What has been known since Froyo x.x is still worth mentioning. Many user have just started their android career because nowadays the hardware and the software are worth it. And once in a while talking about an old known tip is worthwhile especially since nobody else did.
@ demandarin ;-)
Edit on topic (referring to Diamondback):
This was no flame.
Asus shoot themselves in the foot, some people in my thread the same!
Obviously both the feet and so I call trolls by name,
themselves they should blame.
Right? Obviously not, which is a shame.
My only wrong the color of which I was ignorant,
shame on me!

from Asus gets busted in Asus will get the game
I've been using this option since day 1. The problem is not that the wifi doesn't sleep. It's more so that it sucks way too much power when it is on.
I have an iPad2 3g as well which I received as a birthday gift so I kept it and with wifi and 3g always on, I still get 5-7 days of use.
On the Prime its dead under 2 days if always on and 3-4 days if off when asleep.
So it's most likely an optimization issue or driver issue.
Maybe the transmit power should go to low when asleep rather than staying strong.
Who knows. Regardless this can be fixed by Asus if they really look into it.

Actually the iPad has it's SW architecture on the plus side. I think the high battery drain on the TFP (and/or Android in general) is also strongly linked to the number of apps synching in background.
Maybe it can be fixed with drivers. Lowering transmit power sounds good. Could be that Asus optimized to much for the folks complaining about wifi performance....
The setting to turn off wifi while the tablet sleeps makes no sense for my use case. I mean for a wifi only device, it makes not much sense to turn it's connection to the outside off. How will I then receive notifications on gtalk, mail and so on? If I would like to safe power that way, I rather turn it completely off.
For a phone with 3g / edge data connection it might make sense. This applies for the 3g iPad as well.
I agree, it got a bit worse with .21 but for me battery life is still awesome.
Thanks anyway for bringing it to the mind of new users. Although I wouldn't call this a fix but a workaround.

Yes, I agree about the drain but isn't it probably because of the stylish casing! So nothing we can change there, but Asus could clock it down while asleep as you suggest.

My iPad2 goes ding ding ding all night. Lots of apps syncing. 3 email accounts. CNN app, and multiple other apps.
But I think iOS uses a very low power state for background sync while in sleep compared to Android.

Not sure if it's relevant because this was posted for the GS2 but it could also help with wifi drain on the prime.
from this thread: http://forum.xda-developers.com/showpost.php?p=25876666&postcount=3
"FAQ
Q: Wakelocks "wlan_rx_wake" wake up my device constantly what I can do about it?
A: The problem is neither Android nor the kernel, but the router and the (Windows7) network. In the network properties, uncheck "IPv6", disable the service "IP Helper", "Shell Hardware Detection" and "Windows Media Player Network Sharing Service", which provide ongoing Traffic. Then they scored again 98% of deep sleep."
And how you disable ipv6 on your phone/tablet is with a script but the value in the file gets recreated everytime you turn wifi on and off. So if you disable ipv6 then turn wifi off, then back on, ipv6 will be enabled again. I got around this by a tasker profile that will run every time my tablet connects to a wifi network. So it disables ipv6 right away again. You could do this in an init.d script(or in sysctl) as well but then you have the issue of it resetting itself if you turn wifi off/on
If you have tasker create a new profile for when wifi is connected, then run a shell script task, and check run as root. This is the command echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6
to enable it just replace the 1 with a 0. You can also run the command in a terminal window if you just want to test it. I did it for my phone, and I just set it for my prime so I'll see if it drains less battery with it off..

Yes, I agree about the drain but isn't it probably because of the stylish casing! So nothing we can change there, but Asus could clock it down while asleep as you suggest.
You are right I have already changed the op from fix to workaround.

I would just like to say thanks and let you know that I had SOD problems on my prime (as bad as up to once every day in frequency) for a very long time since .21 came out, after trying your work around (several weeks ago) ever since I have not had a single SOD sleep of death issue whatsoever.
I always suspected it was dock recharging causing the SOD fault but maybe it was a bum wifi stack or something, so thank you very much my tab is much more stable because the suggestion you've shared with me.
Unfortunately it does not help any flickering or GPU bugs I tend to get on occasion. I truly hate .21 it is so god awful for GPU, SOD and storage I/O.
I should just man up and downgrade but meh, sif i have the time do it
But yeah, thanks heaps, your workaround is an awesome suggestion.
I am having an issue with my MoPho severely overheating and shutting off. But strangely it only seems to happen when I am outside. The first time I noticed it was when I went fishing. My phone had about 80% charge, and when I picked it up maybe 30 mins later is was scorching hot. To the point that it burnt me. And it had shut off. I didn't have it in the sun or anything. It was in the shade inside a bag. I was not able to get it to turn on even with a battery pull even after it had cooled down. The battery completely drained in a matter of minutes. I couldn't even get it to charge in the truck on the car charger, either. It got too hot on the charger to the point it wouldn't even get a charge. This has happened about 3 or 4 times since. It will go from a full battery, get super hot, and completely drain within minutes. This never used to happen in the house, it was only an issue outside. until today. Went fishing, phone had full charge. It managed to hold the battery for a couple hours, unlike the other times, but eventually got hot and died. Then when I got home, plugged it into the charger and went to sleep, woke up a couple hours later and it was burning hot, and had no charge. Other things on it are acting weird now, as well. The screen keeps turning on and off every few seconds by itself. I don't know what the issue is, but I might have to switch back to stock if I can't find a solution. Because eventually this is going to fry my phone. And I don't want that to happen. It is also a huge inconvenience for your phone battery to drain in a matter of minutes and become a useless paperweight when you are in the middle of nowhere and need a form of communication in an emergency.
Has anyone else had this issue and found a solution?

Many people have experienced overheating problems on our cm9. Some people including self have fixed it by just doing a fresh install of cm9 as it seems like just a fluke. Im sure the fact that were running a gingerbread kernel on ics doesnt help. Also, try dropping the battery down to 1200 from the stock 1300, see if that helps.

Someone mentioned changing the overclock from the stock 1300 down to 1000 in another thread. Is that the same thing as what you're talking about? Or is there a separate setting for the battery? I did try dropping it down to 1000 but that's when the screen started turning on and off by itself. And LWP's stopped working properly. They would get stuck and seizure. Even after I changed it back to the default 1300. So I went into CWM and just reflashed the ROM. No more screen turning on and off or LWP's acting weird. But as far as the overheating problem I can't be sure I guess until I go fishing again or put it in another situation in which it's done it previously.

I work outside every day and its bout 100 degrees out consistantly now... I'm not running cm9 anymore but I've noticed I still get the occasional overheat while its in my pocket, it most definitely gets annoying sometimes having to pull the battery and let everything cool down but I think the benefits outweigh the annoyance level a million to one. I guess what I'm saying is you're not alone friend, it definitely happens to me as well. I have my CPU set to 1k though and messed around with undervolting as well and feel like I get a little better results this way. Keep playing with your settings until you find the one that works best for you is the advice I can give. Good luck!

Yeah its the same thing. Remember, our processor is technicallynot supposed to be over 1000 per core for a reason. People just like to push things to the edge. The whole lwp problem is expected and everyone experiences this with the our ice roms. That also is due to lack of proper 2d libs. But I'm glad most of your problems have subsided. Run your processor at 1000 and I'm sure the overheating will lessen. On a powerful dualcore phone like the photon 1300 from 1000 is miniscule anyway.

Alright. I will try it again. But I just love my LWP's =[ I always have a lwp on. I have never experienced the problem with the lwps until I set the processor to 1000. But I guess it comes down to sacrificing my wallpaper to stop it from overheating. If that's what it takes to fix the problem. Hopefully once the stable version is released everything will work like it should without having to sacrifice anything.
It did overheat again the other day. I did have Watchdog on my phone and I was on facebook messenger the other morning and it started acting up, I had my phone in my hand and within a couple minutes it got burning hot, and then right after, Watchdog popped up with a notification that messenger was above threshhold. It was running at 49% CPU or something. And come to think of it I would always get notifications about fb messenger "misbehaving". So I came to the conclusion that it could be either messenger or watchdog causing most of my problems. I deleted watchdog to see if it fixes my problems. I'm hoping it isn't messenger. Because I need my FB. lol. But I haven't really used messenger on my phone since I deleted watchdog. So we'll see. If that didn't solve it, then I will sacfrifice my lwp and set the processor back to 1000.

Fb messenger gets a lot of hate, i cant say thats your problem but you never know. Try out a chat client called imo from the play store instead. It supports fb as well as others and is leaps and bounds better than fb messenger.

Thank you. I will definitely try that =] Thank you. I really hope it fixes the problem. I can't wait for the stable release. haha
I bought two Nexus 10 when they were first released and I've scrapped one because the battery failed and a huge screen area went yellow and I was getting multiple annoying random reboots every day.
Now my second Nexus 10 is going the same way.
What a load of crap this tablet is, I'm not surprised Google is not updating it for no-one would buy it.
That's interesting....I have a few mates who have the Nexus 10 and none of them have had those problems. They have had theirs since they were released...Maybe you dropped them once?
You just might be an isolated incident. Another mate if mine has the N7 but the only issue is the charger port issue that many other people have.
I have a N4 and the only issue I have is that the camera stops working at times and to fix that I just restart the phone.

No misuse at all and another annoying bug is the way it deletes part of the pin number after a reboot so you have to re-do the pin number.

I am sorry to hear you are having troubles with both N10s. I would surely have the same frustrations were I you.
We have two N10s, his and hers, for about a year and half. They are used for several hours every day, because we are retired and have lots of time to be online or reading books. My wife's N10 runs Purity ROM and is rock solid for her word games and eBay, facebook, shopping, email and all the other stuff. Mine is rock solid for banking, bill pay, surfing and videos. It usually runs CM11, but could be temporarily running something else while playing around with ROMs. We charge our tablets every day, and try never to get below 50% before plugging in.
I do plan to buy at least one N9 when released, not out of need, but, instead, out of curiosity for an Android 3x4 screen format. Fun times ahead for us Nexus fans.

Don't forget nexus 10 is a two years old tablet but it was a gem in its own time. After 2 years we still don't have any tablets with a higher screen resolution than nexus 10. Which makes it perfect for media consumption. I think only galaxy tab s has a better screen nowadays.
It has had its own shortcommings but most of them are by rectified by software updates, like memory leaks or random reboots.
I have purity ROM on my nexus 10 and I have zero reboots or problems. Everything works like a charm after 2 years of heavy usage. The only thing that I envy now is a super amoled screen on my tablet.

I agree, the Nexus Tablet line was literally one of the biggest POS. I owned a Nexus 7 tablet for about six months and never dropped it or anything. The problem started out with ghosting/ghost input touches then later on progressed to half the touch screen not working at all... Although I initially loved it literally became one the biggest let downs ever...
On top of this, I had also read many articles on XDA and elsewhere of people with the same problem trying to send their tablet's in to ASUS for the warranty and they basically just sent the tablets back to them as is with a software upgrade, which didn't help at all since it was a hardware problem.

Mine had worked flawlessly since the week it was released.
I got mine when they released the tablet and I've never had one problem with it.
I got mine first month of release and it was great for about a year. It's still good now but my siblings abused it so now the battery drains quick (used to last all day and some of the next now I'm lucky if it reaches the end of the day) and speakers are chipping paint.
Other than that there no issues though and those are pretty much our fault. The battery problem could be from not using official charger or just charging all night

I bought my shortly after release and have not experienced any problems with it. I have almost exclusively been using the Franco kernel with AOKP. I use it every day in place of my laptop. I can watch movies, youtube, internet, social media, etc. all day on a single charge.
I bought mine around feb/mar 2013.
It's a piece of crap.
Yellow/brownish tint on the screen that is getting bigger as we speak, battery shutdown at 30% (workarounds exist!), overheating, slow response, slow R/W speeds, etc. I have to do a factory reset pretty much every month.
On top of that: Gergle being a b*tch about it because they've deactivated my account (inactivity). Really funny guys.
I don't know what to do.
I guess I'll throw it away, as soon as I have something new. I'll never buy anything touched by Samsung again. No phone, tablet, TV, you name it. The only thing they're good as is NAND.

The problem is: I force the system NOT to shutdown. The battery stays at 0%, but the device keeps running.
This is dangerous. When the CPU ramps up and the voltage is too low it'll cause instability, which you can see by the backlight flickering, the speakers making weird noises, all that bad stuff.
I am not sure how this affects the battery (or the device) physically, since Li-Ion is not very happy when it's "too" discharged. But it'll wear out the battery even faster, I fear. (This is unfunded. I have not enough knowledge about electronics that advanced. But I've read it somewhere. :silly
But, that out of the way: There's an xposed module. I DO NOT recommend using it. It's called DisableCriticalBatteryShutdown, by the user zst123.
You WILL run into fc's of the systemui when plugging the device back in. But the process should restart by itself.
There's a thread on XDA. AGAIN, I DO NOT RECOMMEND USING THIS MODULE.
I got my Nexus 10 shortly after they were released, and though I love it because it's screen is gorgeous and it has front-facing speakers, it is really buggy, and has been since day one.
It freezes and restarts on me probably daily, and always has since it was brand new. In the early days it always happened while using Chrome, and at the time I remember reading that it was a Chrome-specific issue, so I just switched to Firefox in hopes of a better experience.
It was better, for the most part, but eventually it started freezing at other times as well. I still like the tablet, but it definitely has never been a great performer.
I got my Nexus 10 at release, after 1.5 months of Google not shipping it, losing it, telling me that it was coming, etc... Worst customer experience I ever had. I was on the phone with them daily.
When I finally got it it worked fine for a little while but as I put more and more on it and actually tried to use it to stream video, I would get random reboots, freezing, etc...
I've tried relentlessly to talk my wife into letting me unlock it and put a custom ROM on it hoping it would fix things but she would never let me. Now that it's almost two years old, and I barely use it do to all the reboots, etc..., she might finally let me unlock it.
I was really looking forward to getting this tablet when they announced it but with all the problems, for me it pretty much became a $500 paperweight. I use my GS4 so much more than I every used this tablet, even when I'm home.

I have 2 Nex10's. Both bought at launch. One is stable as a rock (thank god it's the wife's or else) but mine is a bit of a dud. Instabilities and crashes since day one.
Not a day goes by that I don't have to do the 3 finger salute to restart because it has frozen solid.
Tried factory resetting, flashed factory images whenever a new one was around and tried different kernels. No change whatsoever.
I believe Samsung's soc is the culprit here, which was also the issue with the chrome chrashes in the early days (GPU drivers that fixed the issue where delayed by Samsung, which was silly as it's a stock Mali GPU).
Never mind the USB connectivity issues that only Samsung devices do. I had no problem connecting any of my other tablets and phones (Nexus 7, 4, 5, Xperia Z, various HTCs, even Nokia Lumias) to my PC. The Nex10? No dice. I had to manually remove any and all USB drivers, do 3 rain dances and pray to the lord of shadows before I got it to work.
Hey everyone. i've had my nexus 9 for a long time now but every now and then i get a few issues with the battery for some reason and i cant find a solution that works tbh.
Right now i'm running android nougat 7.0 and the thing has been great so far but just today i realized that the battery had been draining while i was asleep.
This has been happening before android N as well, on marshmellow. at one point i even had to roll back an OTA update because my battery would drain while the tablet was idle over the course of only 4 hours.
So.. after i rolled back to the more stable version of marshmellow, that stopped happening.
but yea. now i have a similar problem on android N. i just dont understand why this is happening and its super frustrating. before i installed android N i wiped my entire tablet completely clean before i flashed it.
i knowww, its kind of a first world problem. it doesnt happen all the time but when it does its super annoying.
does anyone know what i can do to prevent this from happening? i have set it to disable wifi when screen is off so.. its not downloading or updating apps or anything.. and disabled double tap to wake.. the tablet is basically just lying still on a table all night so dont understand how it can be draining the battery at all.
thanks
sorry, since im new here i cant actually post an image yet or a link to the image.. but basically, android system and android OS is taking up huge chunks of the battery and if i look at graph i can see that my tablet was
"awake" for multiple hours even though the screen was off while i was asleep.
you could try better battery stats, there's a thread here at xda for it, see what's going on with it. I haven't noticed so far but it's only been a day. You may wanna just let it go for a few days and let the system settle, let your cache build, etc....and if you're rooted there's kernels available the you could try out and make some adjustments depending on how you use your tab. Good luck :good:

Thanks for the reply. im gonna consider if betterbatterystats if it doesnt stop draining within a day or two. i need my tablet to function properly by monday.
Last night the exact same thing happened. although this was was even worse i think. theres a tiny little snippet of "screen on" time in the battery data menu. and then it shows the long bar of " awake" throughout the entire night. and apparently this is because of android system and android OS.
it literally drained from 91 % to 36 % over the course of the night... completely unbelievable.
Try disabling all account synching, turning all location settings off, and restarting in Safe Mode. This will limit your device to just the OS and gapps. If you're still getting the battery drain, it's most likely a gapps issue. Unfortunately, I don't know an effective way to remove and replace the built-in gapps in the stock rom.

I've been running marshmallow since day 1 and 7.0 developer preview since day 1 as well. I am typically getting ~4 & 1/2 hours of screen on time with ~30% battery left (not rooted, nothing). If the Google apps aren't the problem, the problem may be with the battery itself where it itself is faulty and needs replacing. A good thing with replacing the battery is that it's fairly easy to do unless you accidentally ripped out the camera with it. If you were to rip out the camera by removing the back cover, then that would definitely be a problem. Memory leak in any of your non-Google apps?
Hey everyone. i think i might have found the reason why my battery is draining sometimes. lately it's been doing fine as it's rather easy to fix.
My theory is that if you put yiur tablet with the screen facing down on a table or something, it may trigger the touch input, even with the screen being off. So it's using some battery cus it thinks you're touching the screen so it has to be ready since.. if someone is touching the screen they would usually turn the device on.. but idk.
it just seems as though the battery drains whenever i put it with screen facing down.

Hey everyone. i've had my nexus 9 for a long time now but every now and then i get a few issues with the battery for some reason and i cant find a solution that works tbh.
Right now i'm running android nougat 7.0 and the thing has been great so far but just today i realized that the battery had been draining while i was asleep.
This has been happening before android N as well, on marshmellow. at one point i even had to roll back an OTA update because my battery would drain while the tablet was idle over the course of only 4 hours.
So.. after i rolled back to the more stable version of marshmellow, that stopped happening.
but yea. now i have a similar problem on android N. i just dont understand why this is happening and its super frustrating. before i installed android N i wiped my entire tablet completely clean before i flashed it.
i knowww, its kind of a first world problem. it doesnt happen all the time but when it does its super annoying.
does anyone know what i can do to prevent this from happening? i have set it to disable wifi when screen is off so.. its not downloading or updating apps or anything.. and disabled double tap to wake.. the tablet is basically just lying still on a table all night so dont understand how it can be draining the battery at all.
thanks
sorry, since im new here i cant actually post an image yet or a link to the image.. but basically, android system and android OS is taking up huge chunks of the battery and if i look at graph i can see that my tablet was
"awake" for multiple hours even though the screen was off while i was asleep.

Hey, there is a possibility that there is a 3rd party (non pre-installed) app that has been causing your N9 not to sleep. This is easy to test for. Just boot your Nexus 9 into safe mode the next time you are going to set it down for a while. This will disable all 3rd party apps. If it was a 3rd party app that was waking your device and draining battery, safe mode should prevent it from doing so. The hard part after that is determining which app is the culprit. Trial and error is the only method, uninstalling 3rd party apps one by one until the problem is fixed.
To boot into safe mode, hit your power button, then touch and hold the power off prompt on your screen. You will then be prompted to restart in safe mode.

FYI - Custom ROMs/Kernels allow you to disable Double Tap To Wake /Swip To Wake. So, if this problem really bothers you, that's one way to fix it.
