Anyone know why my TF701T completely loses all its charge, even when fully charged up, when i close the tablet with keyboard still attached?

I can fully charge it, tap the sleep button top left, close the keyboard, and then less than a day later it has lost all charge and then needs to be fully charged up again.

This is getting really frustrating, otherwise its a great tablet.
Android version 4.4.2

Thanks.

Have you tried a reset and see if the problem still exists without any apps on your tablet? I may be a problem with an app draining the battery.

Just started happening to me too

This just started happening to me a couple days ago. I take my tablet to work, it stays in my backpack powered on but not being used. Most days I get home and it's either still at 100% or at least in the high 90s. Two days ago when I got home it was at 18% and yesterday it was 15%. I'm beginning to suspect some app update is killing it. I haven't changed anything else. I don't have a keyboard. Running the latest CromiX 7.03.

This has been happening for at least 6 months, maybe longer.
Haven't tried a full factory reset and reinstall of apps - I was hoping it might be simpler than that.
No other android devices I have excessively drain the battery (Note2 phone, Nexus 7 tablet) - why should this tablet be different?
Have a battery monitor installed for about 2 weeks and no apps stand out having excessive wake locks. (apart from the battery monitor itself, which is to be expected )

Did you use Netflix?

There is a bug with Netflix that it completely drains the battery on the Tablet after it runs. The workaround I use is to reboot the tablet after I am done with Netflix

This has happened to me since I upgraded to 4.4.2. Since I had only just purchased the TF701T it had very few apps on it and I was able to observe some things via teh power and battery stats;
1. When stored in a bag the battery discharged throughout the day going from 100% to 20% in just over 8 hours
2. The TF701T had woken up every 5 - 10 minutes even when i thought it wasn't meant to
3. Wifi appeared to stay on when it was woken up as it used the most power
4. Google Play Services and Android OS initaited most of the wake ups (approx 70%)

I turned off Google sync and also now turn off Wifi manually when I finish a session. Now I am losing almost zero battery whilst in standby i.e. On with lid closed.

It was the same for me. The battery turned of in 8h without use. I tried to wipe and restore without result.

I re-calibre the battery with the app BatteryRepair. Now my tablet is 50% after 24h unplugged and 3h of use.

Hope it works great for you too.

Ok, quick update;
i wiped the tablet using the Asus tool, which removed all my apps and gave me a clean base to test from.
I noted that there was now no battery drain at this level, with google sync on and wifi on.
I then slowly added the apps i needed (probably over half of them I didn't need - this is always a good time to consolidate)
I then started noticing the keyboard battery was draining even while closed, but not as much as before.
Reading your above posts, i turned off sync, kept on wifi. I still noted a bit of drain.
I then just turned off wifi before closing (left sync on). No drain.
Also i noted, the mouse(pad) always now returns when i open the tablet from sleep.
So for now, i can conclude that the combination of;
having the new Oct 18 patch,
reinitialising the tablet, then reinstalling (& reducing) my apps,
and turning off wifi before closing/sleeping the tablet seems to have stopped the battery drain.

for now ;)
ps. no, i dont use Netflix.

another update:
fully charged the tablet last night to 100%, turned off wifi, then closed the lid.
Opened the next day (10 hours later), charge still 100% on both tablet and keyboard.
Definitely looks like its the wifi, and turning it off before closing stops the drain.

That is what does it for me too.

Only this helped me

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.
Works for 5 hours already.
