Oh good. Haven't been in the thread in a while. Just moved in to the new stock update. So far so good. Had my dock/tablet go from 100/100 to zero/100 while tablet was completely shut off a couple nights ago. Ben having bad drain but that freaked me out.
[Asus Transformer TF701] marcmarshall:
I was having 0 battery until a few months ago. Now it is total overnight. I have been trying every fix I can find. Going to try this now. Thanks.

Update- no success. Back to hair pulling.
[Asus Transformer TF701] marcmarshall:
Do sorry to hear of this. Wishing you blessings and my prayers with you.
[Asus Transformer TF701] norkle:
Great to hear of the positive progress. Hang in there - it must be tough, but glad the rainbow has appeared.

'knocked this up' perfectly understandable in australia :)
[Asus Transformer TF701] Revhead:
Great news about your wife!

I am still on 7.0.0 and have been having a couple of problems lately? I have not upgraded to 7.0.3 because until now I didn't have any problems.

1. The dock keyboard stops working occasionally and I have to phyiscally remove and reattach it before the keyboard is recognised again?

2. I have been returning to find the sdcard in the dock no longer present and I have difficulty getting it to remount. When I pop the card i get an unexpcted removal of storage error even though it is not present. Afer several attempts I got the card to remount but it says there are no files present. If I put the same card in the tablet it reads them fine. If I swap cards I get the same result - I have 2 x 32GB cards?
[Asus Transformer TF701] boldnuts:
I have also the same issue with the dock but some of my keys still work, I have to remove it and reconnect it to be seen again, I don't thick it's the connector issue that some have had as I have no wobble when moving the tablet back and forth in the dock and don't loose the sd card or and keys, so looks like a dock hardware issue, shame as it's only 3 months old and unlocked so no warranty.
[Asus Transformer TF701] marcmarshall:
I'v given up. For awhile a few months ago I was better than good. The keyboard would not wake the tablet when sleeping and I was losing 1% max after 8 hours of docked sleep. Now even though the settings option to disable the keyboard when sleeping hitting any key still wakes the tablet. When I leave it overnight the dock has no charge at all.

These issues with the dock have been going on since I had the TF101. I purchased 9 docks for my 701 before giving up on getting one that would not lose USB connection with the slightest movement of the tablet in the connector. Asus pretends they know nothing of all these problems. They are either lieing or they are complete incompetents.
[Asus Transformer TF701] Revhead:
So there's no chance it could be software? No chance reinstalling or updating the ROM could fix this???
[Asus Transformer TF701] marcmarshall:
For me it is both hardware and software. The design of the dock connector is such that it is constantly losint communication with the dock. There are also battery drain problems when the tablet is docked.
[Asus Transformer TF701] Revhead:
Well nothing ventured, nothing gained.

Upgraded to 7.0.3 and it is now recognising storage in the dock (but for how long?).

Gave the connections between the pad and the dock a bit of a clean with a toothbrush too (can't hurt).

Interestingly the build number is not showing 7.0.3 (is this dependent on the kernel I chose?)

Rebooted and storage is gone again. Keeps flashing message unexpected removal of external storage.. Sometimes the card is shown but reads as empty. The system can't seem to index the files. It knows the card is there because when you remove it you get the external storage removed message???
[Asus Transformer TF701] Revhead:
How to fix a boot loop

Got stuck in a boot loop when I wiped and reinstalled 7.0.3.

By that I mean it tries to reboot but keeps falling back to recovery.

Had me scratching my head for a few minutes. I remembered some kernels can cause this, but unfortunately changing kernels had no effect.

What worked in the end was doing a full wipe, then reinstalling.

And, as and added bonus, my dock storage is showing again (for how long I don't know).

1. Go to clockworkmod recovery.

2. To do this reboot with volume up, power button, and home button all pressed together for a couple of seconds.

3. Go to the Advanced menu and wipe the dalvik cache.

4. Go to mounts and storage.

5. Scroll down to format system and select yes.

6. Scroll down to format data and select yes.

7. Scroll down to format cache and select yes.

8. Now go back and install the rom from the internal or external sd card.

Everything is erased and formatted ready for the new ROM, no old system files, old kernel remnants etc.

Your personal files are safe, this wipe will not wipe the internal sd card and will not wipe the external sd card - all your pictures, mp3s, videos and anything you have downloaded will still be there when you install the new ROM.

What it will wipe is the first 2gb partition which holds the operating system and all personal user data like contacts, bookmarks, APN settings for Internet access, accounts etc.

If you do a Titanium backup of this personal user data it can be restored after you have installed the new rom.

Doing a factory reset doesn't format the system partition, the old system files are still in place until the system partition is erased and formatted.
[Asus Transformer TF701] wolfymozart:
The same dock problem for me!!!
[Asus Transformer TF701] Revhead:
Sucks doesn't it?

Just to let you know tablet is no longer recognising sd card again . . . sigh!

Does voiding your warranty by unlocking the tablet extend to the dock too?
[Asus Transformer TF701] berndblb:
Didn't for me. Unlocked on day 1 and had the dock repaired on RMA a couple of months later. May depend on the laws of your country and if you bought the combo separately or as a unit.... I'm US
[Asus Transformer TF701] superwutze:
i'm still on 7.0.3, never went to the stock rooted version, but since a few days (maybe three weeks, haven't used the tablet a lot until recently) i also have a very strange and heavy drain on the dock battery. also my device is not as stable as it used to be. around half the time the dock isn't responsive when opening the device and has to be redocked. after a night in my backpack the dock is empty and the tablet down to around 50%, sometimes totally empty. also the unit is sometimes very hot in my backpack. i tried to kill all apps before closing and putting it back but without success. still the same phenomena. unfortunately there were quite a lot of updates recently, so i have not even an idea what caused that!

hopefully that will go away as surprisingly as it came, but i doubt it.
[Asus Transformer TF701] berndblb:
There's a lot of chatter across multiple device forums abut mysterious battery drain.

Could be the latest update to Goggle Play Services and the services for wearables (which hardly anybody uses, I am quite sure.....)

For me the drain is not (entirely) related to the dock. It drains just as fast undocked.

I tested the last few days on sbdag's stock rooted version and nothing I did changed a darn thing.

Now back on this rom - we'll see how it does. If I experience the same drain I'll try the ideas from this thread:

[Asus Transformer TF701] Aaroneious:
Just noticed mine was suffering from severe battery drain the last 2 or 3 days. I don't own a dock. I haven't tracked down the culprit yet. Froze a few things with Titanium Backup and disabled autostart for a few more. It's bad drain too, like from 100% down to 20% in a matter of hours of it just sitting not being used at all.
[Asus Transformer TF701] houtx2:
I just did the disable wearable services tweak. Hopefully it does the trick.

EDIT: This did not work for me. Table is running hot and still stays awake a lot when idle.
[Asus Transformer TF701] jhermit:
Same here. No dock and about 2-3 days ago, it started draining like mad. I went back to my 12/7 backup and restored hoping that it was an update in the last few days, but the drain was still there. I did not let it update anything, but I am certain that on 12/7-9 I did not have the drain since I was traveling and using it heavily.

Very puzzling. It is almost like a Google end interaction with our tablets rather than an update to our tablets themselves. From everything I have been reading, it is not specific to the ROM but rather appears to be 4.4 related.

The net of it is that my tablet has to be powered off since it never goes to sleep. Very annoying.
[Asus Transformer TF701] berndblb:
Or something that is common to all Android devices. Like, Google apps......

What is your Google Play Services version please? If you have an older version, the theory that it is the latest update to it would be questionable.

Super annoying!!!
[Asus Transformer TF701] jhermit:
I am on 6.5.87 (1599771-036).

I followed the post on this thread regarding disabling user presence as well as the Fitness and Wearable services and for the first time in a couple of days, it went to sleep. I will keep monitoring, but it appears to work. Thank you for posting the reference!
[Asus Transformer TF701] berndblb:
So you were on the latest GP Services version even on your backup...

I am going to try this now. It drained 7% in the last 45 min... [emoji95]
[Asus Transformer TF701] Revhead:
More than likely the drain is related to location services.

You know that little box you tick that says let me track you even when I'm asleep?

I usually say no to this but in a fit of sheer stupidity I said yes when I did the latest install. Guess what now I've got drain which I didn't have before???
[Asus Transformer TF701] superwutze:
can't be location services in my case. i always deactivate it (and just checked). but who knows what a 'i don't want that crap' tickmark is to google, maybe they track anyways since the last updates.
[Asus Transformer TF701] superwutze:
i disabled those services and haven't lost a single percent since this morning, also the device was cool as usual in my backpack. looking forward to the next google updates and the next problems :)
[Asus Transformer TF701] jhermit:
Well, after 24 hours since making the change, the tablet battery drain is less, but it is still pretty bad at about 5% per hour (vs 10%/hour yesterday). It used to be about .5% per hour a couple of weeks ago. So I keep looking...
[Asus Transformer TF701] houtx2:
I agree. I made the changes too and have the same results. I find that when the Kernel Wakelock in BetterBatteryStats says "battery" the tablet will not sleep. I wish I knew what that meant. It is such a generic term it's impossible to google.
[Asus Transformer TF701] superwutze:
wrote my last post and was happy, put the tablet into my backpack and went to work.

took it out a few minutes ago, burning hot and nearly empty, docked the keyboard and it rebooted instantaneously.

i guess that post was posted too soon. :(
[Asus Transformer TF701] jhermit:
It looks like google updated the Google Play Services app today, but I do not have it yet...

https://play.google.com/store/apps/details?id=com.google.android.gms&hl=en

UPDATE: Actually rebooted and the new one came in. The level is 6.5.99 (1642632-036)
[Asus Transformer TF701] Revhead:
That used to happen a lot for me with my old TF201 on Androwook. Got to the point where I had to turn it off each time. The problem went away when I installed CROMI-X 5.4.

With regard to the TF701T, it wasn't happening on 7.0.0 that I remember?
[Asus Transformer TF701] loner.:
You lost me on this. What did you do and how did you do it? I can't seem to find said procedure so I can try it. :)
[Asus Transformer TF701] Lopburi:
Look like this new Google Play Services 6.5.99 update solved the problem for me so far so good.
[Asus Transformer TF701] yeatsie:
installed this rom, seems good, but finding my touchpad on the keyboard dock doesnt come back always after i open the tablet again..

Its weird though, as the other buttons like brightness up/down, touchpad on/off, home key etc all seem to work, so that suggests the problem is in software, not hardware?

Anyone got a fix for getting the touchpad to come back?

cheers
[Asus Transformer TF701] wolfymozart:
I've the same version but the problem persists for me
[Asus Transformer TF701] Lopburi:
Yep.. I spoke too soon the problem still persists :( Before I went to bed the battery was at 96% woke up with only 19% left about 8 hours idle and screen off but 0 sec of deep sleep FTH. Go back to square 1.
[Asus Transformer TF701] GrouchyPunisher:
Same here, problem persists. I've been going crazy the past week Greenifying things I've never had to, and was "glad" to see I'm not the only one with this problem. Very annoying that Google would break the ability to deep sleep, and not fix it already.
[Asus Transformer TF701] loner.:
No matter what Rom I use, I get really bad battery drain. It has something to do with Google Play services. I hope there is a fix soon. [emoji35]
[Asus Transformer TF701] Revhead:
Just to reiterate.

I don't recall having the battery drain problem on 7.0.0 - does anyone else?
[Asus Transformer TF701] GrouchyPunisher:
No, i dont. But this is unrelated to the ROM and cropped up recently across multiple devices. Even if you went back to version 7.0.0, your Google services would automatically get updated on that ROM and you'd be back to where we are now. :(

[Asus Transformer TF701] jhermit:
Would reverting back to the 4.3 Android make this go away. My tablet is useless with this bug.
[Asus Transformer TF701] berndblb:
I doubt it. GP services will automatically update to it's latest version (even if you have auto updates disabled - really Google???) and it seems to be GP services itself or an app calling a GP service that does not allow the tablet to reach deep sleep.

Check out the thread I linked to ^^^^

So far I and two more users seem to have solved it by using the Autostarts app by Michael Elsdorfer
[Asus Transformer TF701] mikmock:
Amplify?

I found a band-aid using an xposed module called "Amplify" it started out as "NLPUnbounce" or something like that. i set all the "Safe to limit" wakelocks rather aggressively at 1800-3600 seconds and i got 99% deep sleep leaving it alone for 24hrs and it was at 80% battery life and no heat.

it's certainly not a fix but it sure beats the alternative for now.

just skimmed thru the last few pages, sorry if someone else posted this temporary (i hope) fix. :D
[Asus Transformer TF701] karapoutsoglou:
great rom all around, cant wait for some kernel tweaks maybe in future updates.
[Asus Transformer TF701] yeatsie:
Ok, i've managed to slow the battery drain on my TF701 (for now). Here's how i was able to do it:

(these all rely on your tablet being rooted, and thanks to the other commenters in this thread for the tips)

- install the Disable Services app, this allows you to disable specific components of the main culprit, the Google Play system service.

In this app, go to the System tab, sort by Running num to see the top offenders, click on Google Play Services which will be at the top of the list, then filter and uncheck (disable) the Play processes under the following matches;

"wear"

"fitness"

"presence"

"locationhistory"

- install the Greenify app (this works well in combination with the below app WLD)

- install the Wakelock Detector app. Use this to see the other apps that are causing the most wakelocks, click on them and send them to Greenify to hibernate them.

I followed the above procedure last night, then I closed the tablet with around 80% battery.

I woke the tablet today 12 hours later, and it was still just below 80%.

Update: it was still dropping around 10% in 12 hours and i wasn't getting any deepsleep reported in Wakelock Detector, so have also done the following;

- deleted the /system/vendor/lib files for the Nvidia Widevine DRM as mentioned in below post #503 by buda5767.

- added all the "Safe to limit" wakelocks in Amplify app and bumped them from 240 to 3600 secs as also mentioned in previous post #500 by Mikmock.

Will see how that goes and report back.

Update 2:

Wow, 7 hours with the lid closed (wifi and sync left on), opened now and battery level hasn't dropped from its levels of 99%/100% (keyboard/tablet). Outstanding! Will update on any noticable drm issues if they occur.

Another observation: the tablet is stone cold when left closed, rather than always being warm previously. another great sign.

Also, for some reason, i lose touch input on the tablet screen after my first sleep - anyone else getting this side effect? Probably disabled one too many services..
[Asus Transformer TF701] buda5767:
I read this in a other forum and help at the moment.

I found nvavp is used by NVIDIA's Widevine DRM proprietary plugins.

I removed all proprietary DRM plugins from /system/vendor/lib.

Code:

/system/vendor/lib/drm

/system/vendor/lib/mediadrm

/system/vendor/lib/libWVStreamControlAPI_L1.so

/system/vendor/lib/libwvdrm_L1.so

/system/vendor/lib/libwvm.so

Then, the idle battary life becomes normal.

I supposed these thingy are used by Google Play Video/Music, that why some people think disable Google Play Services helps. Althogh I guess it is a bug in NVIDIA's proprietary DRM plugins causes this issue.

I never used Widevine DRM stuff, deleting those files seems to have no drawback for me.
[Asus Transformer TF701] jhermit:
Yay! You rock. For the first time in over a week my tablet has slept for an hour in a row.

Hopefully it will continue.

UPDATE: This indeed fixed the problem. Only lost 2% overnight
[Asus Transformer TF701] asinglenoob:
Sir, you win the Internet today. This fix worked perfectly! Thanks so much for posting this! This is the one thing that has worked for me! Looks like we have a solution!
[Asus Transformer TF701] superwutze:
thanks a lot, finally my device is usable again! just 1% drain in 10 hours and 99% deep sleep!!!
[Asus Transformer TF701] berndblb:
Do you guys notice any problems with DRM content like music, videos, books you got from Google Play?
[Asus Transformer TF701] asinglenoob:
I stream almost everything from Netflix and Spotify so I don't know for sure but I'll check and report back.
[Asus Transformer TF701] yeatsie:
Well done! Have done the same and will report back.

Looks like the battery drain due to nvavp has been noticed & bug-reported in the CM snapshots few days ago - mentions it may have been initiated in the last Asus 4.4 update?

Cause sounds close to what i'm reading in these threads.

Here's the CM bug report : https://jira.cyanogenmod.org/browse/CYAN-6124
[Asus Transformer TF701] superwutze:
except for apps i don't use google play at all, so i won't notice.
[Asus Transformer TF701] asinglenoob:
Tested the free Lord of the Rings movie that Google Play gave out a while ago, seemed to have no issues playing without those DRM files so I think you'll be fine removing them.
[Asus Transformer TF701] yeatsie:
think i got a bit too agressive with my wakelock process isolation, i seem to have lost touch input to the screen.

Touch works fine when i first reboot, but after i turn off the screen, and then come back, it seems to stop.

I'm just using the touchpad on the keyboard for now as workaround.

can anyone point me to the service i need to check/re-enable?

thanks

Update: its ok, solved it.

It was permissions not being set right on the /system/vendor/lib/ files i replaced back when i dropped in the new version of the problem file.
[Asus Transformer TF701] berndblb:
What "new version" of which problem file?
[Asus Transformer TF701] ein777er:
Dear budo5767!

I can confirm that : libwvdrmengine.so

is the only file you have to erease - > let the tablett sleep like a baby again ;)

thx man!!:good:

kind regards ein777er
[Asus Transformer TF701] superwutze:
i just checked my backup from those libs: libwvdrmengine.so is the only valid drm lib in the /system/vendor/lib tree, all those links are broken, they point to a non-valid location (/system/vendor/lib.org doesn't exist). so it has to be that one.
[Asus Transformer TF701] yeatsie:
berndlb, i replaced the file libwvdrmengine.so as buda5767 mentions in post #510 with the one in that repository, under the asus directory branch.

seemed to do the trick.
[Asus Transformer TF701] tschmid:
Is the also a solution for cm11 users? Deleting the lib?

Gesendet von meinem LG-D855 mit Tapatalk
[Asus Transformer TF701] asinglenoob:
Yes, I'm on CM11 and it worked great for me, 97% of screen off time is spent sleeping!
[Asus Transformer TF701] yeatsie:
nope, spoke too soon.. this again stopped it going into deep sleep (checked with Wakelock Detector).

I've just moved that libwvdrmengine.so file out into a temp directory for now, rebooted, and the tablet is again getting deep sleep recorded. Think i'll just leave it out for now until it gets fixed properly.

DRM doesnt seem adversly affected, i was able to play Gravity on Google Movies & TV app with no issue.

Hey sbdags,

Hope you and your wife are well... hoping that 2015 will be kind to you and yours.

What would you recommend for those of us who want to run your ROM, but yet also the latest (.29 bootloader) update from ASUS? Does this need to be built into your ROM, or is there some way I can flash both? I did attempt to flash the update overtop of Cromi-X, but no dice. Bootloader actually reports .29 but system settings says otherwise and the drain is not fixed.

Of course, I could remove that problematic file (ie. the first workaround we found for the battery drain)... but I'd rather just be running with the latest drivers and etc. in the latest update, and your awesome system.

Thank you in advance!
[Asus Transformer TF701] berndblb:
I'm sure he will update this rom as soon as he has time and space for it. I think we all should show a lot of patience here and NOT ask for updates.... please.

But great that you confirmed that the .29 bootloader runs well with CROMi-X! :laugh:

Your Build Number shows you only the rom base. Whatever you read in the bootloader menu is what you are running.

To fix the battery drain just remove the lib file and keep enjoying your tablet. I pretty much guarantee that the new update even when integrated properly into the rom (wish I could do it, but I can't) does not make any difference in user space.
[Asus Transformer TF701] Trevor_g:
Simply a question - not asking for an update; just advice.

Thanks for your reply. But to that last point if yours: actually, it seems there are some fairly considerable fixes that might indeed affect user experience. For example:
