[Asus Transformer TF700] jtrosky:
FYI, after re-calibrating my batteries (by fulling draining and fully re-charging), I drained the tablet down to 70% and let it sleep for 4 hours - very little drain. I then got the battery levels back to 70% (tab) and 100% (dock), undocked and re-docked and let it sleep for 4 hours again and got the exact same amount of drain (very little). So I'm definitely not seeing the drain problem.

Personally, I think that we should all completely drain and recharge the devices and then run the tests again - at least the 70% test - both before un-docking and after re-docking. Maybe it's just a battery calibration issue and there really is not "drain problem"?

We can always do the exact same suite of tests next weekend (if not before) after re-calibrating our batteries and see what happens... My devices are still in the "testing" state - I haven't loaded any other apps on my tablet...

I can't really test using facebook or twitter though as I don't even have a facebook or twitter account!

EDIT: I do think that we should also make sure we are testing without a full-sized SD card in the dock next time too, just to remove that variable....
[Asus Transformer TF700] jtrosky:
FYI - corrected this in the OP - sorry about the mixup!
[Asus Transformer TF700] jtrosky:
In hindsight, I'm thinking that it would have also been better to have a few more testers...

So, to recap, I think that we should run the tests again next weekend, with the following differences:

- More testers

- Re-calibrate battery before starting the tests.

- No SD card in the dock

- 3 hour intervals instead of 4 (to help reduce the testing time for each scenario)

Can anyone think of any other changes and/or different scenarios for the next tests? I do think that these tests were useful - it seems that nobody had any major drain issues except one tester, and even that tester could not re-duplicate the drain issue again. Can't explain the reasoning for the high drain for that one tester though - and that is bothering me...
[Asus Transformer TF700] workdowg:
Just an update... Still going from Scenario #4 battery drain, I'm going on until it dies. Here is what I've done so far:

View attachment tab_testing.xls
[Asus Transformer TF700] workdowg:
Edit: It was actually only 55 hours since last full charge.
[Asus Transformer TF700] fsured:
I don't know why I got that drain. Its been about 36hr of no use and the drain hasn't occurred. Perhaps something remained that kept the battery information in the dock cell? It could have carried over whatever the cause is and when it fully died it was reset when charged back up. That is. If they keep any battery stats in the battery itself. Is there an app to recalibrate them or just letting the tablet and dock automatically shut off do it.
[Asus Transformer TF700] jtrosky:
Actually, it seems that I'm still have battery calibration issues. Noticed today that my tablet was staying @ 100% for quite some time, so I started the "Battery Drainer" app again and it took it quite some time to move from 100% again...

I'm going to see how far it goes down before turning off again. This time, I'm going to charge it back up while powered off and see if that re-calibrates the batteries correctly. Don't understand why it's so out of whack and why I can't seem to re-calibrate it... Strange...

EDIT: Yep, sure enough, it shut off at 46% this time! Plugged charger directly into tablet and turned off from recovery... We'll see if that recalibrates it...
[Asus Transformer TF700] jtrosky:
Damn! Even after fully discharging, recharging without the dock (while powered off) and then cold-booting Android (via power+volume down "menu"), my battery calibration is *still* way off! - it's actually getting worse! Now, it's powering off at 48% (originally it started powering off at 46%, I think)...

I'm out of ideas at this point and may just file a SquareTrade claim - maybe it's a hardware problem with the battery... Maybe they'll give me $$ instead of a replacement and then I could use the $$ to put towards a new TF701! :)

Does anyone else have *any* ideas on how I may be able to correctly re-calibrate my TF700 battery?

Thanks!
[Asus Transformer TF700] sbdags:
The one I have seen I you have to make sure it is completely dead. That means don't recharge it for 24 to 48 hours after it dies.
[Asus Transformer TF700] workdowg:
So I ended up 66 hours AFTER draining to 70% and it was still 30%! I drained the rest this morning and now I'm charging. I have heard this over and over again, but now I will add only 1 or 2 apps in a 4-8 hours period and track them. This will be as needed, not just to fill the tablet :) .
[Asus Transformer TF700] drewski_1:
Did you undock between your 1st & 2nd sessions on 10/28 where 1st ended at 43/71 and 2nd started at 0/71? Or the dock fully drained in those 2 hrs?
[Asus Transformer TF700] workdowg:
That was when I went to TWRP and wiped then Flashed 5.1.1. So basically the dock was replacing the tablet as needed..
[Asus Transformer TF700] jtrosky:
[MENTION=3971563]workdowg[/MENTION] - did you always have the dock drain issue before running these tests? I'm really curious to see what, if anything, brings the drain problem back! At least the testing was beneficial in some way, right? :)
[Asus Transformer TF700] workdowg:
Yes, I've had the drain issue since CROMi 4 something. Just last week i was out of town without my charger and had it drain without use from 0/50 to power off in about 4 hours.

I just got done recharging, undocked it and powered it on. I'm using it for a while, maybe 10% then re-dock. I will be keeping my Excel splashes while using it this week until the next testing.

---------- Post added at 05:06 PM ---------- Previous post was at 04:52 PM ----------

From the CROMi thread.

I know nothing about this setting. I'll check too though.

[MENTION=3985971]acraigl[/MENTION] or [MENTION=518363]sbdags[/MENTION] Edit: Where is this setting, I don't see it?
[Asus Transformer TF700] drewski_1:
They're talking about the Asus Connect Dock, which is different from the Keyboard Dock

http://www.asus.com/Tablet_Mobile_Accessories/Connect_Dock/
[Asus Transformer TF700] jtrosky:
The setting is available via the keyboard dock as well, but you only see it if you use a USB->Ethernet adapter... That's part of the problem, if you enable the setting while the ethernet adapter is in the USB port on the keyboard dock and then disconnect the USB adapter without first disabling the setting, the tablet will never "deep sleep" and there is no way to disable the setting without the USB->Ethernet adapter connected (the setting only show up when the USB->Ethernet adapter is connected to the USB port).
[Asus Transformer TF700] drewski_1:
Good to know. I did get my Tab & Keyboard Dock as refurbished.

Wonder if this setting could have been set by original owner and not refurb'd out?
[Asus Transformer TF700] jtrosky:
I believe that a fresh install of any ROM would overwrite the setting. The only way that I could see it "coming back" is if you restored a Nandroid backup from when the setting was set (like what [MENTION=518363]sbdags[/MENTION] mentioned in the CROMi-X thread). Otherwise, I don't think the setting would "stick" between ROM installs.
[Asus Transformer TF700] hendrixlebt:
Ethernet active

Hi, I'm watching the TF700 threads for quite a while now and I'm usings sbdags ROM (up to 5.1, atm 3.47 again).

First: sbdags, thank you very much for this fantastic ROM, it made the TF700 usable.

Regarding the drain: In a changelog for Android 4.2 I found, that Ethernet is now 'enabled by default'.

As a new member, I'm not allowed to post a link yet, but you can find the info by just googeling 'tf700 deactivate ethernet'.

My first finding was on 'androidpolice.com' 'Android rolling out now to the ASUS......'

If you don't find it, just add following to the url, when you are on the androipolice page:

/2013/04/03/android-4-2-rolling-out-now-to-the-asus-transformer-pad-infinity-tf700-in-the-u-s/

I hope, this helps the specialists in this forum, to find out more.
[Asus Transformer TF700] drewski_1:
nice find!
[Asus Transformer TF700] jtrosky:
FYI - I *finally* got my battery to re-calibrate! I tried everything - even letting it power off by itself (fully drain) and letting is sit for a day and it still wouldn't re-calibrate.

Then, another user [MENTION=5443706]viewsonica[/MENTION]) sent me a PM with the following process to re-calibrate the battery. While I had my doubts that it would actually work, it did work! My device went all of the way down below 2% before shutting itself off! Here is the exact process that [MENTION=5443706]viewsonica[/MENTION] recommended:

1. charge up 100%

2. use it for 30 mins or a hour (still 100% maybe?)

3. shut down,cold boot start

4. after restart, delete batterystats.bin (root required),do nothing then just shut down the machine.

5. leave it off for a hour or two.

6. cold boot start the machine

if sucess, you should see significant battery % dropped (10%+). this procedure works on my machine, hope it does the same on yours.

I know that many have said that the "batterystats.bin" file is un-related, but at the same time, I figured it couldn't hurt... So happy to be back to a realistic battery level indicator again!

Again, thank you [MENTION=5443706]viewsonica[/MENTION]!

Also, regarding the "ethernet defaults to on" change, I don't think it's related to our battery drain problem since there are a lot of people that don't have the drain problem. It could be related to the non-keyboard-dock drain, but I really don't think it's the cause of the drain for folks with the keyboard dock, or else everyone would have the problem. I'd be willing to bet that most people do *not* have the drain problem.

Just to confirm, I'll connect my USB->Ehternet adapter and see what the default Ethernet setting is and report back.

Regardless, thanks for posting the information!!
[Asus Transformer TF700] jtrosky:
Ok, I connected my USB->Ethernet adapter and now it makes sense... It used to be that even when connecting a USB->Ethernet adapter, you still had to go into the settings and "Enable" Ethernet. Now, it's enabled by default, but the option to always keep the Ethernet port "active" (even while in deep sleep) is still disabled by default - and that is the option that causes the battery drain (since the tablet never deep sleeps when that option is active).

So I don't think this has anything to do with the "dock drain" problem - at least for the keyboard docks. No idea about the non-keyboard-dock.

Here is a screenshot of the Ethernet settings screen after I connected my USB->Ethernet adapter:

Hope that helps!

Thanks.
[Asus Transformer TF700] workdowg:
So I've gone a couple more days. This is only my second charge since we started last weekend. I got another 54.25 hours with some use and some abuse. Again my plan is to keep close track of what I install. I also just flashed a modified dual-boot kernel (based on _that5 patches) so I will be keeping an even closer watch on my battery.
[Asus Transformer TF700] Drenus:
Here's a plot of workdowg's battery stats (based on end times and end percentages). [MENTION=3971563]workdowg[/MENTION], does it look about right?

And what is the plan for going forward? Are we trying to find some thing/app that causes a drain and for everyone else to try and duplicate it?
[Asus Transformer TF700] jtrosky:
Honestly, I'm not sure where to go from here... I think we've pretty much proved that a base install does not have the drain problem - now we just need to figure out what app is causing the problem. I'm assuming it's a very "common" app since so many people seemed to have the drain problem. I think it would really help if we could get some other users that have the drain problem to perform the tests, and then slowly add their apps back into the mix, just like [MENTION=3971563]workdowg[/MENTION] is doing. I would think that would allow us to identify the offending app or configuration setting that is causing the drain.

Since I've never experienced the drain, I'm guessing that its an app that I don't normally use, so I'm not sure how to help at this point...
[Asus Transformer TF700] sbdags:
I think it will be location or WiFi or both that cause it. Prime suspects first would be Google maps or Google plus.
[Asus Transformer TF700] liney_2000:
I'd say your right. Turning off "Access to my location" and "WIFI" stops the drain.
[Asus Transformer TF700] jtrosky:
There has to be something more to it though - I always have location access and wifi enabled 24x7 and do not have the drain.

Maybe a particular app that accesses the location and/or wifi radios are the cause though - I think that was what [MENTION=518363]sbdags[/MENTION] meant. Definitely not Maps as that was loaded during all of our testing. Google Plus is a posibility though (among a handful of other potential apps).
[Asus Transformer TF700] JoinTheRealms:
I could always compile you guys a kernel with wakelocks disabled to force the problem away ? :)

---------- Post added at 12:36 AM ---------- Previous post was at 12:25 AM ----------

btw does this drain issue occur on earlier updates (4.1 etc?)
[Asus Transformer TF700] workdowg:
I stopped testing, but I'm still being vigilant. I fell asleep with Linux Deploy running (it keeps the screen on) for 2 hours. I lost the last of my dock battery, 20% and only about 20% of pad. All in all battery life is great again. BTW, I'm using the _that-based hybrid dual boot kernel again.

From my LG-G2.
[Asus Transformer TF700] fsured:
Question, how exactly is the dock battery supposed to function? For me its a rapid drain once the tablet hits 70%. In a span of 2-3hrs the dock will go from full down to about 20% and charge the tablet back up to 90%. That is not an even ratio. It doesn't matter what I'm doing with the tablet during that time. Is it designed so that all power for the device is coming from the dock as it "charges" the battery in the tablet which creates this rapid drain?

I've moved back to cromni 5.1, _that kernal v5 with 1gig-1.3gig-1.8gig, fsync disabled, no voltage changes from the selection, 213 dpi, browser2ram, and basic app installs. I wasn't seeing this when testing the tablet during the scenarios. I will include screen shots of what applications I installed in case any of them are known to be drains. I didn't restore any from titanium but did clean installs from the market.
[Asus Transformer TF700] jtrosky:
Is it possible that the DPI change is causing the drain somehow?? Thats one thing that I never change - I always use 240 DPI... Can't think of why that would cause a high drain, but you never know!
[Asus Transformer TF700] berndblb:
Doubt it.... Have been on 213 forever - no drain.
[Asus Transformer TF700] _that:
The dock battery is smaller than the tablet battery and charging is not 100% efficient, but 80% dock should be much more than 20% tablet.

This behavior could indicate that some app on your tablet thinks the device is on AC power and prevents it from sleeping. Check your wake locks.
[Asus Transformer TF700] workdowg:
Android itself thinks that _that :). Checking the battery stats shows the time from undocking... Sometimes.

From my LG-G2.
[Asus Transformer TF700] fsured:
Thanks everyone for the replies. My tab/dock are at 100%. I have an app to check wakelocks. I will leave it alone for 4hrs to see what gets registered and then use the tablet to 70% so the battery kicks on in the dock. Then let it sit again and see what is found.
[Asus Transformer TF700] workdowg:
The drain maybe back... I left the tablet about 3 hrs ago and it went from 0/81 to 0/61. I charged both yesterday afternoon and this morning after very little use the dock was at 0. The only 2 changes over the last 3 days are I installed Dropsync and turned off wifi optimiztion (to speed up my wifi without toggling it of and on). I'll let it run down to around 0/20 and let it charge overnight, then start keeping my log again. I may have to do with any app that runs in the background trying to keep some files in sync? Maybe I should now install wake lock detector again...
[Asus Transformer TF700] workdowg:
Lost 10% in the last 4 hours without use... grrr
[Asus Transformer TF700] jtrosky:
Maybe it's as simple as the Wifi Optimization settings?!? Can you try re-enabling that setting and see if the drain goes away, without changing anything else? I believe the setting is enabled by default, so all of our testing had it enabled...
[Asus Transformer TF700] sbdags:
Try uninstalling dropbox to see if it helps?
[Asus Transformer TF700] workdowg:
I didn'tget back on to see your response and charged it. I'll reenable WiFi optimization and start keeping my log tonight.

Dropbox is usually the first app I install... I also usually install Dropsync earlier too... So I'll try jtrosky first...

Edit: Dropbox is installed as a system app during my last cromi install...
[Asus Transformer TF700] sbdags:
What happens if you were to leave it out of the install routine? Dropbox is installed to /data so you should be able to uninstall it.

I'm only saying this as you said it was one of the things you did differently.
[Asus Transformer TF700] workdowg:
I understand where you are coming from... After the official testing, I continued on my own and the very first app installed was Dropbox without the picture sync (:insert funny here: I don't carry around the tablet to use as a 10.5" X 7" camera :silly: ). I've had at least 2 day on a charge since (except when playing with Linux through kexecboot).

What changed is I installed Dropsync and turned off WiFi optimization.

Edit: So far overnight

6.5 hrs 99/91 to 93/78 - No use, WiFi optimization on

In my other tests 6 hrs use to only drop the tablet by 2-3 percent.

I'll keep testing, for me it may be Dropsync because like I said it tries to look for new files to sync constantly. Yet, I have used the app since CROMi 3.4ish... It may have been an update sometime that changed it?
[Asus Transformer TF700] sbdags:
Well I used to have keyboard drain - I solved it though (I sold my keyboard dock :p :D). Lol. I never used dropbox sync but I'd uninstall the things that changed to see if it helped anyway.
[Asus Transformer TF700] workdowg:
Absolutely, I just can't see why it would affect me now seeing I used it so long. BTW... Only thing turning WiFi optimization back on did was slow my lan speeds...

3 hrs of no use went from 93/78 to 90/71... Not good. Bye bye Dropsync...
[Asus Transformer TF700] jtrosky:
Please update us when you find out if Dropsync is the culprit in this case... Sure seems that "excessive drain" issue was purely app-related, just as everyone expected! Now we just need to start documenting the "offending" apps, I guess!

Thank you for the updates -they are much appreciated!
[Asus Transformer TF700] collindv:
On my tf300 I get the dock battery drain on a fresh install.
[Asus Transformer TF700] jtrosky:
^^That's what folks thought about their TF700 too - until they did the tests in the beginning of this thread... If you can, try running the tests and see if your drain goes away (assuming that you run CROMi-X)!
[Asus Transformer TF700] berndblb:
I have Dropsync on every installation since CROMi 3.2 and I don't have the drain.

What are your settings for Autosync Interval settings?

I have it on 24 h AutoSync and the Instant Upload feature for changed/new files in monitored folders checked.
[Asus Transformer TF700] collindv:
I installed cromi before I read this thread but I did a similar setup as test #1 (though I changed default options, kernels, etc.) and definitely noticed the dock drain (unable to deep sleep, losing 5-10% per hour when off). If I get a chance I will try to replicate test 1 exactly.
[Asus Transformer TF700] workdowg:
As always 1 hour auto and instant upload. I wonder if it was the combimation of dropsync and the wifi optimzation this time....
[Asus Transformer TF700] collindv:
I have a TF300T and just completed scenario 1. Here is my background and results.

CROMi-X Version: 5.1.2 US Deodex

Kernel type and version - that v4

PAD Version: PAD-EC20T-0216

MobileDock Version: DOCK-EC20N-0207

Scenario 1

Start tablet 100%, dock 96%

Finish tablet 71%, dock 73%

9 hours

The only changes I made from scenario 1 were those necessary for the tf300 vs tf700 and I did not format internal storage (by accident, actually formatted my microSD :( )

Scenario 2 is currently running, will update later but do not anticipate a change since I see the drain right off the bat.

*Edit1

Scenario 2

Start tablet 100%, dock 99%

Finish tablet 86%, dock 83%

5 hours

*Edit2

Scenario 3

Start tablet 100%, dock NA%

Finish tablet 99%, dock NA%

5 hours

That6-oc Kernel

I was experiencing the rapid battery drain problem, too.

However, once I flashed the "kernel-10.6.1.14.10-that6-oc.zip" kernel, the problem vanished. It doesn't matter if I leave my wifi on -- there's no drain. No idea why.

I tested by flashing other kernels. One called hundsbua or something. The drain returned.

Give it a shot and let the thread know what happens.
[Asus Transformer TF700] collindv:
Updated my post with the first 3 scenarios. First two both show massive battery drain while connected to the dock without so much as changing or installing a thing. Scenario 3 shows typical battery drain when detached from dock.

If I get a chance I will try and reinstall with that v6 but I think I have tried that in the past and has the same issues.
[Asus Transformer TF700] collindv:
Reinstalled with that v6 kernel, cromi-x 5.2, and wiped internal storage, results no better:

Scenario 1

Start tablet 100%, dock 100%

Finish tablet 86%, dock 37%

10 hours
[Asus Transformer TF700] jtrosky:
This is very interesting - I wonder why the TF300 is getting different results than the TF700 when performing the same tests.

None of the TF700 users had battery drain issues with any of the test scenarios... Maybe a setting defaults differently on the TF300? Not sure...
[Asus Transformer TF700] workdowg:
My testing has been shot for the last few days. I'm using the tablet pretty heavy and actually it seems my battery life is better like that :D

I'll be trying again this weekend to see if all is better. I did up to 5.2a and removed Dropsync... We'll see.
[Asus Transformer TF700] sbdags:
[MENTION=4447351]robgee789[/MENTION] on the TF300 thread said freezing google+ solved his drain issues

Note the following also:

[Asus Transformer TF700] jtrosky:
Definitely not Google+ for me as I've never used or froze it and I've never had the battery drain. That's what so crazy about this battery drain - it seems that some apps affect battery life for some, but not others... Very hard to pinpoint the actual cause (or causes).
[Asus Transformer TF700] gixxer340:
I almost always have rapid battery drain on my pad when connected to the dock. I can actually get more time out of the tab if it is not connected to the dock. I wish there was a way to turn off the charging capability of the dock all together (or be able to turn it on only when you want it to charge) because I use the doc all the time and I can't trust even leaving it over night without the battery being severely drained. I have just taken to disconnecting it from the dock or shutting it all the way off when I won't be using it for a while. Really aggravating but at least I know it will still be at about the same charge I left it rather than opening it up to find that it is useless.

Just my .02

Jeff
[Asus Transformer TF700] sbdags:
2 users now confirmed freezing Google plus fixed the drain.

Getting weirder and weirder......
[Asus Transformer TF700] collindv:
I am fairly certain I didn't even install Google plus as I never use it. I will check when I get home tonight though.
[Asus Transformer TF700] gixxer340:
I don't even have Google plus on my tablet (at least I don't have any applications named that) so that definitely is not my issue.

I am using CROMi 5.2 a BTW

Jeff
[Asus Transformer TF700] sbdags:
Which is why I think various apps can cause it... Something causes the tab to not deep sleep when docked....
