[Q] Battery usage data not available

Since Asus folks seem to be visiting this forum, I thought I'd mention a bug in the most current firmware (US 5/1/2011). If you go to Settings, About Tablet, Battery use, you'll note that it says "Battery usage data not available." It should provide a list of the system components and apps that have used particular percentages of battery life.
Hopefully that'll be fixed soon (along with the inordinately high battery burn rate in standby)...

if you click on the graph above that message you get limited info. But agree it could be better.

There was actually a previous thread on this issue. There's actually supposed to be more info displayed on that page (there is on the Xoom), but for some reason the Transformer just gets that error.

Yes, precisely. Seems like the software's not getting a reading from a sensor or something. It's definitely a bug.

3.1 Update
I just got the Android 3.1 update on my Transformer, and this bug is still there: no usage data availible. It may be minor, but its very disapointing they didn't bother to, or for some reason couldn't, fix this.

That's not the data that this thread is about. When you go to About Tablet, Battery Use, you should first see a list of what apps/system components are using the most battery life. Tapping the graph gives completely different information about system status (e.g., wifi on, screen on, charging, etc.).
On the Xoom, this works as it should. On the TF, all we get is the "Battery usage data not available" error.

Confirmed.

Here's another vote for Asus to fix this.

Is there any fix for this? Even with the newest FOTA update (July 16th), my TF is still showing "Battery usage data is not available." Something is sucking my battery down and I need to figure out what it is..
What's going on with Asus here?

About battery drain issues on A500

There is a big debate about the issue of the telephony system draining the battery life on the Iconia A500.
One way to solve the problem is renaming the .apk causing it, but it can brick your device if you do a factory reset. The other aproach is to edit a single file and set the cell conection to GSM (so no constant polling).
But, IMHO, a process doesn't, consume power. The power is consumed by the hardware of the device. The mW consumed by a process should be the sum of display + system + wifi + other hardware during the period of time the process has been active.
However, the device suffering from a "Cell Standby" issue is a wifi only version, and it drains nearly a third of energy compared to the display comssuotion (a purely hardware part).
So, my question is, if something is consuming so much energy, could it be a hardware device?. Maybe the only part missing on the A500 is a less than 2$ sim socket.
Anybody brave enough to do a tear down of his device? (And do a lot of pictures, a la ifixit)

Hmm, I like your thinking. I might have a go. Mine arrives tomorrow.

I'd be very interested in this also.
I've noticed that on the status screen from the about screen on my wife's A500 it lists the sku as 3G and one of the version numbers is listed as A501. (Though the firmware is A500)

I am on my second A500 (first one appeared to have wifi issues) and neither has had a battery drain issue while using or in sleep mode. I do use Advanced Task Manager to exit any non-system tasks, but that should not make much of a difference.
I lose no more than 5% after ten hours in sleep mode and a full charged tablet lasts me a little over eight hours with (for me) heavy use. I have yet to have it die on me and if I do less Flash streaming, it lasts ten hours.
Of course, "use" is very subjective, which a a reason battery threads kind of tend to spin in circles.

Yes, I see the same thing, about 5-6% when sleeping overnight, and I think the chatter about battery drain is meaningless. Sure, it says "cell standby" is 30% but,
a) That is 30% of a small number , i.e., 30% of 6% = <2% loss
b) I tried some of the proposed solutions in the Battery Drain thread in the dev section - there was little difference before and after
I think the whole thing is a waste of effortg - the battery drain is no more than I had using CM7 on a rooted Nook Color - less than 1% per hour and I think all the related threads are solutions looking for a problem!

according to his post, there is no mobile broadband module. so if there is any battery drain from "cell signal" it would be because the system isn't able to sleep.
android simply thinks there is no service and isn't designed to ignore the cellular state when the hardware isn't present.

It's very clear from the pictures that there is no cellular module inside the wifi version
But, it 's also clear, the telephony system is polling for data, and waking up constantly the device (even when there's no hardware attached!!).
It's an Acer-centric problem, let's hope they fix it in the next update.

I'm simply at a complete loss as to how my phone can be so awake ALL the time.
If anybody could give me ANY insight as to why it might be the case, I'd REALLY appreciate it.
Also, I can post my alarmdump.txt if anybody wants to see it.
Again, any and ALL help would be greatly appreciated. Feel free to ask me for any more info that might be of use in diagnosing the problem.

That NYC map app seems to be the culprit. As well as the Google Search widget, for some reason.
Uninstall the app, remove the widget, reboot and see if it's much better

im also curious about modem fastdormancy... i froze it because it was a wakelock culprit, but am getting really fast battery drain as well. not sure exactly what modem fastdormancy does tho

http://groups.google.com/group/android-platform/browse_thread/thread/9cb9c3e94da63110?pli=1
So basically, Modem Fast Dormancy = do not freeze. In my understanding, it has to do with the radio and disabling it when not in use, or something to that affect. I haven't studied it, but that's a quick 10 second synopsis from reading that article. I would stay away from disabling it.

Right on. And thanks for the info.
When I froze ADW I also UNfroze Fastdormancy, and then rebooted, so hopefully that'll help.
What about the wakelocks for Event Log Services?
Does anybody know if there's a way to find out exactly what that is, and if there's anything I can do about it?
Thanks for the input so far guys I REALLY appreciate, and little by little I think things are working out.

You're showing 27 hours there..................many people struggle to get 1/2 of that. I am one of the few who gets 28-30 hrs from full charge with moderate usage. I think it's fair to say you have fairly decent battery life, even with only low usage. I wouldn't complain too much.................just keep trying to make it better!

The thing is, he might have good battery life compared to others but his screen was barely on, he shouldn't be having all those wake locks. I have a similar amount too. If we could get this settled our 1 day battery life might turn into 2 days which would be amazing. I'm sure many people's phones are like this.

Yup bro this is exactly it.
It might be good battery life- but I'm not using my phone at all.
After unfreezing Modem Fastdormancy I've definitely got less unexplained blue in the "awake" time graph. I also froze ADW and that seemed to help.
Thing is, there is still lot of mysterious chunks when my phone is awake.
BetterBatteryStats says Alarm Manager and Event Log services are to blame (top two- represent a substantial percentage of the partial wakelocks and thus time awake).
I'm about to terminal emulator dumpsys my alarmdump.txt, but is there a similar solution for Event Log Services that will allow me to see EXACTLY what's putting it at the top? Only clue it gives is that it's apparently "Google Services."
Past that I've got no clue what it's pointing to.
If I get the Event Log Services fixed, I'd venture to say that would solve a LOT of problems for me.
Thank you guys for everything so far. You laid out some really good and interesting ideas- ones that I definitely wouldn't have thought of.
I'm very, very appreciative, and if it's not too much trouble, bros, KEEP IT COMING!
Ultimately, I want OTHERS to be able to reference this thread in their quest for a better Atrix, and maybe even a better android phone in general!

Quick question bros:
If I get my alarm manager dump, will that have any or all of the things contributing to the Event Log Services wakelock?
Like I've been saying, it looks like all I need to solve this is some breakdown of the Event Log Services to see what's putting it at the top.

I honestly always had battery issues with cm7 keeping the phone awake. I switched back to Alien ROM an now my battery life is back to normal, around 42hours. I also saw great improvement when I uninstalled Watchdog while I was on cm7 and so thus I have never reinstalled it again.

Well,
Due to this post I checked my Atrix and saw that it wont go to sleep as well, and stay practically always awake. I started using AntTek App manager to freeze some apps that worked all the time (mainly Facebook and an israeli VOD app) and the phone started to go in sleep. I dont know how it will affect the battery life (which is about 16 hours from 100% to ~5%, with data always open), but I will test it for now and report once I have some news...
BTW Im running CM7-Ba2tF, with faux123 enhanced 1.0 Ghz Kernel, and UV.

Battery life in standby?

I did a little experiment with battery life, particularly in standby mode.
Wifi is on, and the weather/clock widget updates every 2 or 4 hours.
After 24 hours not using it at all, battery life went down to about 94%.
On an ipad2, after 24 hours, it is at 99%.
On, ipad2, most notifications if not all are turned off. Could this be the reason for the discrepancy? Any ideas to make it better? Should I have weather update 1 every 24 hours and update manually as needed?
I notice I cannot set the update interval for mail? Is it because it is push and not pull?

Id be greatful with that kind of battery life. Honestly.

I have it turn my wifi off while screen off and with build.prop tweaks I get 7 days b4 I have to charge... Or... Get juice defender in market and it will handle the wifi and syncing to give you much greater battery life.

It lost 6% in 24 hours. That means it will take over 16 days to drain. I doubt many users will see this as a problem.
I guess you could uninstall any widgets you have and keep it in power saving mode. Turn off wifi. Check the apps section in the settings menu and see which ones are running in the background and uninstall them.
Otherwise, buy an ipad if you want ipad specs.

I'm at 87% at 2 days and 10 hours right now. I have FW .29 and SeanZ's tweaked build.prop. I'm happy with it personally.

Personally I've been pretty thrilled with my battery life. I've never had a device before that would still be at 99% after four-five hours on standby tweaks or not - and the biggest tweak I've done is disabling weather (I've gotta save something for my phone to do).

Get the keyboard and use it like a docking station.
The tablet slips in it pretty easily.

I'm not really happy with the standby time so when I'm not around or sleeping I shut it down.

Probably shutting down WiFi is the most important battery saver. Either by hand or with an app.
edit: Except apps producing wakelocks, of cource. Better Battery Stats helps.

what is this tweaked build.prop and where do I get it? Is root required?

Battery consumption Tablet/Dock Tips for Better battery life.

So I thought of making a thread on your experiences with the battery consumption ratio depending on use etc. My main reason of doing this is because I suspect my dock has a bad battery and I would like to see you guys experience with your tablet/dock combo.
Noticed much difference between power saving, balanced and performance mode?
Processor wise I know each has a rating of 1ghz,1.1ghz and 1.2ghz. I dont see how this would make a big impact in battery life. Now I dont know if these also regulate anything else than the cpu frequency as to make it a noticeable thing.
Whats's the ratio of your Tablet/dock charging? ( what I mean is once your tablet reaches 70% and dock kicks in to charge how much battery would it be left on the dock after tablet reaches 90% wich is point where dock stops charging..
If I leave it charging without using it my dock is left with about 55% battery.
Last night I left the tablet at 52% and the dock fully charged so I left the tablet in sleep mode and charging with the dock. when I come to check on it battery was at 90% dock at 25% . I'm curious if the scaling is alright or am I having a performance loss.
I noticed the dock discharging while it is not supplying battery to the table ( By the time my tablet reaches 70% for the dock to kick in to charge the dock has gone down to 98%).
The biggest power drain is definitely screen brightness though this IPS display seems really nice indoors no more than 20% brightness seems to be needed.
I would also like it if we could post your advice for a better battery life on these wonderful tablets to later on make a recollection of all and post them on 2nd Post
I'll try to keep up and be adding em there.
Well this is what I got in my head so far if your willing to post any other experiences or advice I would gladly appreciate it.
I'm somewhat of a complete noob, I'm here to learn and share my experience with other users.

Battery life tips.
1. If distance is not an issue use bluetooth tethering instead of wifi tethering. It consumes less battery on both devices.
2.Try using the brightness level you need not max it out like most people do.
3.If your an active user on wi-fi, turn on setting for wifi not go to sleep. Every time tablet goes to sleep mode it would be disabling and enabling Wi-fi wich in many devices this has proven to consume more battery than keeping an active connection.
This list will keep growing as more tips are posted.

This is a well timed thread, since I have been having battery issues and the tablet on its own is not the problem. For whatever reason, the dock and tablet together equals massive battery drain in sleep mode, where the tablet on its own only uses one percentage point over night. The majority of both batteries are drained if docked in sleep mode.
I charged the dock to full on its own and unplugged it and will check this evening to see status.
Tablet on own =
Tablet docked = :silly:

Well when I am not using my tablet for sleeping or working I usually just shut it down. Doesn't make sense to me to just always have it on. I'm usually away from it for long periods of time and it doesn't take long to boot up. Plus if I go to use it later in the day or a few days later I'm not looking for my charger because I fully charged it before shutting it down. I keep a laptop/computer mentality with it where if I'm not using it turn it off.

I do not think there is any firmware in the dock itself. I think it is a pure slave device that is controlled by the tablet. The tablet on own does not have a drain issue, but when docked they do together.
On my second dock now with same result.
The tablet and dock together ironically seems to have the same battery life in sleep mode as my Q2670 Lenovo 14" gaming laptop = bad I was hoping the dock and tablet combo would be just as efficient as an Android tablet on own and avoid having to cold start when using it (that seems so Windows to me).

Asus already knows about this problems. Its due to bad software in the keyboard dock (yes there is software for it/ only Asus can access it.) Its actually B.S. the only fix is to send dock to Asus and pay shipping urself. And they'll fix and send back. Prob about a month later
Or you can use the tweeked build.prob like I did. Shuck will allow deep sleep while docked.
Deep sleep = no battory drain
Just be careful with changing build.prob

No kitties here. As stated, they both work fine on their own and have had two docks. Testing another 300 yielded the same result.
The problem is the two pieces together. I think the sleep mode is borked when docked and bleeding power at a non user level.

So... back to battery saving tips.
I get scary long battery life by just reducing screen brightness. Would like to mess with build.prop but haven't yet. I know there is replace n go's out there but I want to find out which settings do what specifically. Still looking for more information on the subject.

My battery life:
Docked and using fairly heavy- about ten hours
Docked and in sleep mode- Both batteries dead in 14 hours
Undocked and using fairly heavy about seven hours
Undocked for over 12 hours tablet = 98% Another time was 99%
Undocked, the dock went 24 hours = "100"%
Ironically, my problem is with the device docked in sleep mode. Two docks, two tablets- same issue. No info showing an app or media task causing it, so lower level bios issue. Both tabs newest firmware, no clue what the docks are/were. Have one each now.

Those having problems, check "Settings/Asus Customised Setting/Mobile Dock Battery Saving Mode"
Enable it and see if it matters
