looks fairly normal... looks like about 6 hours with the screen on, that's more then I would ever ask for
i can't quite tell how low your battery is from that picture but it seems to be about in line with the anandtech results.
I know that it is supposdly not needed, but I run Task Killer on the tablet and that seems to help things run more minimally as well.
Just an Idea?!
When I go to that screen I get a message saying that the information about battery usage is not available, should I enable something to monitor my battery usage?
thanks

There are supposed to be two screens of battery information. Where it says "Battery usage information not available," it should show which applications are using battery life; the fact that it doesn't is a TF bug (e.g., on the Xoom, it shows this info). Tapping on the graph will take you to a second screen that shows what system components (e.g., wifi, screen, etc.) have been used, for how long. This does work on the TF.
I'm really looking forward to Asus fixing this in a firmware update. It's difficult to diagnose what's using battery life without it, although I believe there are some apps that will do the same. Haven't had time to explore them, myself, but since my battery lasts plenty long for my use, I haven't worried too much about it.

Looks pretty good if your screen was on the whole time. About on par with what they say it would be.

Depending on your screen brightness (at the lowest setting OR higher than 60%) and what you did while the screen was on (Simple web browsing OR watch HD movies/play 3D games etc..), I would say that is normal to above average battery life.
Thanks. I had the screen on about 70% of the time. When I did, I was on the internet, watching youtube & playing angry birds. I was also in the Adobe PDF app reading my textbook. All while listening to pandora the whole time.
Also, if you don't mind it not updating stuff when the screen if off (I have a phone so I don't need it to check my email when I'm not around) you should change your WiFi sleep policy to turn off when the screen is off.
This allows it to deep sleep and it will use almost no battery when the screen is off.

Thanks that's good to know, but sometimes the facebook notifications are useful.
My Transformer with 1.4 Prime und Clemsyn OC Kernel is going to "Deep Sleep" even with WiFi on.

Correct.
Let me be more precise:
If you turn the WiFi off with the screen, the whole device will enter a deep sleep (CPU and radio) and use much less power than if you allow the radio to stay on.

my battery does not drain my opinion.
So your battery goes from 100% to 0% in a little over 3 hours? You need a new battery.
Nah man it was fine before.. just after this rom its dying like crazy, its not as bad as 100-0 in 3 hrs tho.
every once in a while I stumble on a Rom / Kernel combination that does this. It could also be a rouge app that is being reported as system.
Try this: install OSMonitor (because the system doesnt give you specific details) and in the setting have it sort by load, then find out what is taking the most percentage of CPU. Long press on that item and select Watch Log. See if there are errors or redundant messages that keep popping up. That will find your issue.

hey man thats very helpfull, thanks so much..LOl but i just flashed back to evils sense rom.. so lemem see if this is consistent. Thanks man.
I get great battery using miui ROM with kernal 2.6.35.4 [email protected]#12. ALSO let battery drain completely and charge fully without turning it on. Then boot to recovery and wipe battery stats. Conditioning and the right kernal / ROM combo has my battery holding up great! Hope it helps! =D

+1, with setcpu
I'd suggest you try CM6 and SetCPU. Both have dramatically helped increase battery life for my N1. I never used to get one whole day's worth backup before, but now I do, sometimes a little more than 24hours (when not used quite a lot).
For me, I found the biggest battery drain to be signal strength.. Even more so than 3G/WiFi or brightness. In an area with low cell signal, the antenna seems to be constantly trying to reconnect and it kills my battery life in a couple hours. If im in an area with strong signal, I can leave everything on (gps, wifi, bt, 3g) and get all day service easily.
I flashed P6800XXLQ2 everything is butter smooth and rock solid stable, but... it chews battery like crazy when it idles.
I had 30% batt, locked it and went to sleep. This morning I found it dead. If you look at the battery curve it always goes down at almost the same slope, does not matter you use it, or not.
EDIT
I tried wiping battery stats and disabling WiFi wile locked. Still the same.
I follow below suggestion and it seems to work.

I had the same issue having my WiFi off. I had to turn it On and then Tablet started working for days just as before
Turn on - for longer battery life, weird, but that works

So which of these I should chose?
Keep Wi-Fi on during sleep if you turn this off it’ll help extend your battery’s life when the device is put into sleep mode.

Always.
OH WOW! Last night I disabled WIFI & Mobile data and locked my device. It had 59% battery. Now it's 58%!!! After 10 hours. There are some serious problems with LQ2 power management.
It aways goes down this straight slope. Does not matter if I use my tab at all. But last night?
So phase 2 of my test, I will use WIFI only, and no mobile data.

some times this happened to me also ... and then I noticed because some application still active in the background eg game and youtube internet browser. even after I quit .
I did experience also my galaxy tab 7.7 was warm /hot ... this was because the game and internet browser still active in the background.
So after that I always "closed all applications" from "task manager" ... no more battery issue or warm /hot issue again.
OK I have disabled mobile data entire day and set to disable wifi when locked. My tab was almost unused all day and this happened.
IT IS WIFI RELATED!
I recently got a replacement for one of my Nexus 4s and I'm having horrible battery life.
The battery monitor app built into the stock android does not seem to help much when it comes to monitoring battery life.
There is no way to reset the information, so that one can properly calculate whether applying certain setting/app changes have effected battery life or not.
As of now; It shows the "Screen" as using 38% of the battery, and "Phone Idle" as 14%.

I'm not sure how this is possible, as the phone has hardly been used since I received the replacement 4 days ago.
I've been avoiding using it, while waiting for the screen protectors to arrive.
How is it possible that the Screen percentage is greater than the Phone Idle? I assuming something is preventing the screen from turning off... but whenever I glance at the phone sitting on my desk the screen is always black..
Not sure what could be causing the phone to not put the screen to sleep, as I have only installed 2 apps.. Apex Launcher and Google Voice.
Apex Launcher is not even running (at least not as the default launcher). Also I've only used the phone to make 4 short phone calls, totaling 45 min.
When looking at the graph (inside the battery app) it shows the Screen On more than Awake.
Anyone have any Ideas?? Or should I send this replacement back due to poor battery?
And does anyone know how to reset the data in the Batter Monitor app, so that I can test changes?
Come to the conclusion that Apex might be the 'cause of the battery drain.
I removed Apex (Pro), powered off the phone, and charged to 100% (Atleast thats what the phone said) Powered on, then powered back off and placed back on charger... Phone has been off the Charger, Powered on for 24+hrs now and I'm getting a 78% batter reading..
Screen: 8%
Phone Idle: 19%
Stats as they should be.
So it seems Apex was preventing the screen from going into "sleep" mode..
Which is a shame, because there goes the Homescreen I worked hard on..
Give nova a try.

I tried Nova, even have the Pro version.. It doesn't seem to want to play nice with the Single Screen Wallpaper I made in photoshop..
Maybe I'm just missing a setting somewhere.. Will try again.
Apex has nothing to do with "putting the screen to sleep" if the screen is off it is off.

Just backup the homescreen that you made, and report the problem to Apex's developers. If they fixed it, you could put it back on =)
btw is it the homescreen shown on your signature?
hi guys,
im troubleshooting my battery problem on this phone. just need some thoughts.
the drain is over 2%/hr when the phone is in sleep with flight mode on and nfc on.

the day before i tried this with the network on nfc on, data and wifi off and the consumption was about the same.
i have yet to try flight mode on and nfc off, but i wouldn't think that nfc would use that much.
i use greenify to put a lot of apps to hibernate so they wont wake the phone.
starting to think my battery isnt performing right anymore.
Sent from my GT-I9500 using Tapatalk 2
17% in 6.5hrs, airplane mode, no nfc.
the phone is definitely going to sleep.
i could leave the network on and nfc too, difference isnt big at all.
any idea is appreciated. leaning towards bad battery here..
Sent from my GT-I9500 using Tapatalk 2
Why not remove all the extra apps, and see if anything changes. Then, you can install one by one when things are clearer.
i would believe if an app cause the drain with the screen off then it is probably causing a wake lock.
which doesnt show at all. is there any otherway an app can drain the battery without wakelock?
Sent from my GT-I9500 using Tapatalk 2
I don't really see drain? 2% an hour is not that much. In my opinion it's normal.
If you insist on lowering it, then try the following:
- Different rom
- Different modem
- New battery
And search for some guides to lower your battery usage.
You have to experiment yourself.
it didnt use that much before. in 15 hrs i got a bit over an hour screen time before it hit 0.
anyway, just loaded romswitcher, going to see if it happens with CM too. and airplane mode on.
starting to think the battery is going bad already

I average about 0.5% drain during sleep.
See the link in my signature to find out how. I've got a whole guide.
Have you checked the serial number on your battery? If it starts with BD then it's stuffed Samsung should still swap it for free I think.
thanks for all the replies guys.
yes 0.5 drain should be normal when it sleeps.
just tried this using CM rom and it looks all good there, so its not the battery.
going to remove some experimental settings in greenify to see if that helps.

I purchased my 6P roughly 2 weeks ago and I'm not seeing this amazing battery life of everyone else's.. The best I've gotten was 4hrs screen on time with 25% battery remaining. I've tried tons of ROM and kernel combinations, as well as being on stock with locked bootloader, the battery life seems worse with kernels, and the same with stock based Roms. Below is my current SOT with stock rooted, stock kernel. Is there something wrong with my battery? Considering calling huawei for a new battery? This is pretty **** battery. My galaxy S5 had better. I constantly check my CPU States, it does deep sleep perfectly fine. No abnormal wakelocks, I don't even have Facebook installed. The 4 hr SOT I did achieve was with greenify and amplify, which I don't think I need for a phone with this kind of battery...

Depends on a few things. Could be a rogue app, wifi wakelock, or really poor signal.
You could try stock and no apps for a day and see how it performs then.

the apps i use are twitter, whatsapp, tapatalk, slide for reddit, snapchat, instagram, open camera, and neko atsume. thats pretty much it. Of course cpu spy for monitoring, and sometimes i do notice wifi taking up a bit of battery, but even if i disable it and it goes away, the battery life is still poor. I have a moto 360 and I usually have it paired via bluetooth. I also use google now but i set the GPS mode to either device only or battery saving mode. reverting to bone stock google images locked bootloader to see if it makes a difference, again.. even if the wifi isnt draining.. still is poor. I did monitor my signal and i get very good LTE signal all over my city, so I can rule that out. Would huawei honour this request? I am located in Canada if it matters. Also i dont think its app related because i use the same apps on my S5 and the battery is better on it, which doesnt make sense.
Have you tried turning off WiFi scanning and Bluetooth scanning? They're pretty much useless but consumes battery.
Go to Settings > Location > Menu > Scanning > toggle both settings off

So I have had my phone on for two days now and charged back to 100 of course. Total screen on time over that period is 3 hrs.. This is brutal. Phones at 58% right now. I'm noticing this (screen shot) is this the culprit and does huawei do warranty in Canada?
