I seems like we have a discrepancy in how much battery life a TF uses in standby. Some folks seem to be burning <1%/hour, others >3%/hour. Obviously, this makes a huge difference in the total time a TF can be expected to last on a charge.
Please indicate how much yours burns per hour. Please ONLY answer if you run your TF as follows:
1. NOT in airplane mode
2. With wifi in the default (run in background) configuration
What setting is to run wifi in the background?
Also, would the number of apps (singned in) and thinks like exchange emails factor into this?

Yep, a lot of things could impact this. But, the dichotomy seems so clear-cut (literally, <1%/hour for some people vs. >3%/hour for others) that I don't think those things by themselves can account for the difference.

I understand and agree. There should be some type of baseline. can you explain what Wifi setting you mentioned above? I have 3 options - Sleep when screen is off, Never when plugged in and Never - I know thats not exactly how they read but its something like that.

The default is to "Never" disconnect...
Dunno how many %/hour, but I've gotten from 14 hours to 17 hours.
Picked up the transformer once in a while, put it down, etc..
Here's a screenshot of the 14hr one, charged it at the end for a few minutes.

So you don't think the amount of data being communicated per application affects battery use in idle?
What do you think about signal strength from the WAP? (being further from the WiFi router, in another room, many walls and objects between the unit and the WAP)

I'm comparing my results to what I'm seeing on the Xoom, which is pretty much identically configured to my TF (same email accounts, same apps installed and running, used with the same routers, etc.). The Xoom uses well under 1%/hour on standby, the TF right around 3.5%/hour.
I'very configured my TF to turn WiFi off when sleeping.
Yesterday my TF was unplugged and unused for a full 24 hours for an 8% battery drain.

The reason there will be discrepencies between peoples devices is because everyone installs different apps. It's these apps that drain the battery more/less, so install a battery monitoring app and check the logs every few days. If you're losing more than 1% on standby per hour, then get a task killer program and tasker, and set up schedules to turn off apps at times you dont need them. Also make sure you have actually set the battery app up properly, by changing the rating it thinks the battery is (to 6600mA) instead of any default value it has.

If you are using Battery Monitor Widget then it's from settings>monitoring preferences>battery capacity. Default was 1200mA on mine originally. If you're using some other app, I've no idea.
As an update, I decided to go ahead and do a factory restore, just for kicks. I'm not experiencing much closer standby performance to my Xoom, about 1%/hour or maybe a bit less. In four hours since the restore, I've lost 5% battery life, and that includes a bit of use.
It's possible that the battery just hasn't calibrated since the restore, and so I'll report back if things return to what they were before. At this point, though, I'm hopeful that something was corrupted or misconfigured, and that a factory restore did indeed resolve the issue.

Coolthanks for the info will have to check out that app. Right now i am using battery indicator pro whicb does not have a option to change battery capacity
Another update after the factory reset: charged the TF to 100% and unplugged at midnight. At 8:00am this morning it was at 78%, so roughly 2.75%/hour discharge rate. At 10:00am (also only on standby) it was at 74%, so 2.6%/hour total for the 10 hours.
The Xoom was at 48% at 8:00am (forgot to note its battery life at midnight), and at 10:00am (also on standby) was at 47%. So, the Xoom on standby is burning .5%/hour, which has been my general experience with it.
Both the Xoom and the TF are configured with the same email accounts and settings, the same general configuration (wifi, etc.), and the same apps except for the Asus apps. Since my experience on standby was roughly the same with the original (non-updated) TF build, I don't think it's the Asus apps that are causing the burn.
If most others were experiencing the same thing, I'd write this off as a purely academic exercise. 2.5%/hour burn rate on standby isn't terrible, particularly since I tend to charge every night anyways. My concern, though, is that if others are getting <1%/hour with the same basic settings, and as I'm getting on the Xoom for sure, then the question becomes: is there something wrong with my TF specifically?
Well my transformer is doing better than that. I lost only 3 over 5 hours. Overnight from 10 to 10 battery went from 33 to 27 percent so looking at 0.6 % per hour. Btw I have wifi set to turn off with screen off. Why do I need wifi going if I can't see the screen. For mail when would wake the device it checks the accounts immediately. So........

I've had my TF with me most of the day letting friends play around with it so it's had what I would consider "normal" use.
Starting at 100% this morning when I left and now has 65% after ~8 hours. (See attached screenshot)
I am battery anal too but anyone else feel like discussing a 2% drain difference in idle is kind of ridiculous.. no one runs exactly the same stuff on their devices of course it will be different... to be honest if you are concered about battery drain during idle.. you obviously leave your device unused alot... in which case battery life doesn't matter a great deal cuz you aren't using it hahhha

Disagree with you. I think standby life is very important because the tablet is something you wanna pickup and have immediate access to for information a nd media without always Worrying if the battery's has enough juice. My nook color can go several days on stby and 3 to 4 days of casual use with standby. This tab doing same stuff is giving me 36 hours tops.
Cm7 on nook color has sleep issues and so doesn't enter deep sleep and so battery drain is about 2% instead of. 2% per hour on stock nook.
maybe our devices aren't sleeping deeply and draining much faster.
Something a Dev. can check?

Ok I think I found an issue with my infinity and need some confirmation. Here is the test. Charge tablet to full. I remove from charger and spend 10-15 minutes browsing the Web. Now check battery usage. Is Wifi your number on power drain? Here is what mine looks like.

For comparison I used my xoom tablet for 10-15 minutes doing similar activities and my wifi power usage was around 2%.
Also just an FYI I'm not in a strange wifi environment that creates any issues. I'm about 6 feet from my wifi hub and I noticed this usage today after work where wifi was between 50-60% of my total usage and that was on my work wifi.
Anyway I'd be really interested to hear if anyone is seeing a similar issue. I also created a ticket with Asus asking about this issue.
I hope you know that the stock battery stats are very unreliable. Under a better battery stats app, I've found that wifi isn't quite as consuming as apps, so I think the system stats are incorrect

Your is what I'd expect. In fact you got 91% after two hours. That is better than my xoom. This explains why some people claim good performance and battery life. Mine will be below 90% in like 30 minutes usage.
I think there is a wifi issue and this might be a way of identifying bad tablets. I'll see what the ASUS support people say and post it here. The bad news is this looks like a hardware issue...
Before I completely get excited can you make sure your wifi is always on. Go to settings, wifi, advanced, make sure keep wifi on during sleep is always.

The screenshot is also missing the "ASUS Customzied setting" menu option on the left, right under Apps. Looks like either custom ROM or not an ASUS tablet perhaps.
For what it is worth, I have noticed the same issue with my Wifi eating up tons of battery. I haven't done any tests, but it certainly feels like my battery is draining pretty quickly with Wifi on. It is certainly draining much faster than my TF101....I would expect that to be the case to some extent because of the processor and screen upgrade, but not this much. There is another thread going on TranformerForums about the same issue. Someone reported that leaving their device fully charged with Wifi turned on overnight had drained it down to 19% by morning, with no use.
Not sure yet if this is a real issue, but it seems strange that Wifi would use significantly more battery than Screen.

Don't rely on the battery usage screen. It's not like it's got an ammeter coupled to every battery drain. It just calculates percentages based on the information it got, it's all guesswork and needs lot of calibration to be correct. The reason WiFi is blamed as the major drain is probably that it's running all the time (and its power usage might not be calibrated for the battery usage screen). The stats won't know at all if e.g. the kernel gets stuck in an infinite loop and drains the battery...
Personally, I only trust the info the battery usage screen gives me about apps. If an app has a high percentage, it's probably not right. The rest of the breakdown is mostly bogus.

Well something is eating battery fast.. I have my xoom and my infinity sitting side by side right now and my xoom is at 80% battery after 2:30 hours on while the Infinity is at 62% after 2:41 on. So the infinity is draining battery about twice as fast as my xoom. And the xoom shows the top battery usage as the screen where wifi isn't even making the list.

There are already some threads that discuss this topic. The battery meter has a bit of a bug where it shows the WiFi % based on how long the wifi has been connected rather than how much actual power it has used. Mine does the same thing with 85% battery atm but it has been running off of the charger for 1d 13h and still has 37% left.
It is a battery meter issue and not an energy drain issue.
Xoom is now 68% after 3:30
Infinity is now 50% after 3:40

Well, the Infinity has more hardware to give power to.
However, my Infinity is at 62% after 10 hours... Most (about 80%) of that time, it's been sleeping (but on), though. Did you actively use both your Xoom and Infinity during the reported time?
How does the detailed battery usage screen (touch the graph in the normal battery usage screen) look? Here's mine (the gap is a reboot):

Yes I've been kinda using them. I've had them in google plus and swipe around every once in awhile.
I left for lunch and turned them both off.
infinity is now at 40% and xoom is at 55%. a bit over 6 hours since both were pulled off the charger. Screen has been on over 4 hours.
Here is the current status of infinity 37 percent
Sent from my ASUS Transformer Pad TF700T using Tapatalk 2
Here is the picture of my xoom at 53%
From just eyeballing the two graphs it looks like the infinity sleeps better where my xoom is staying active constantly. None the less when the screen is on the infinity consumes power quite a bit faster.
It is clear that the xoom does quite a bit better on battery life than the infinity.
Mine does this too, but battery life is solid

Battery Drain
I just got mine yesterday and the battery drain is unexceptionable. I fully charged it last night and then was off and on it this morning before going to work. After getting into the office it was more than 50% drained and before lunch it was well below 30%. I have the TF101 and it hasn't been charged in two days and it is still at 79% with everything turned on.
I have not had a chance to look into this but I find that amount of drainage excessive.
On a side note I pretty much just have the stock apps running on this. I did just do a cold boot so I will see if that helps at all.

I am still w bit confused wheather 2 units I had was faulty or not. ASUS definitely has bad QC. I was under the impression with constant browsing with low screen brightness and balance mode, we can only get 5-6 hours of battery. But some review sites state more and I even so similar discussion back when original transformer was released. So I want to verify.
Does anyone get over 8 hours of battery in balance mode, low screen brightness while constantly browsing? The easiest way to test is browse for an hour and see how much battery loss. If 20%, you get only 5 like I did.
last time i checked, i had 7.5 hours of screen on and wifi was actually my biggest battery hog by a 2:1 ratio, and still had 30 something % left. i dont have battery issues, i'm not sure if my transformer is a very recent build but i dont have ANY of the issues reported on this forum. no clicking, bleeping, battery problems or any other. my only problem is really just software related just like a lot of other have, lag, reboots, force close, but i know asus will fix that shortly

Did you have a dock? That's impressive number even if you didn't use browser at all. Still far superior to way I had. Do you mind browse formalize 30min and see how much battery drop you see? Also ,let me know which mode and brightness you used.

no of course no dock on...if i have a dock on i can last days. The most i lasted with a dock and moderate use like reading about 1-1.5 hours of zinio magazines, checking a few youtube videos, some fbooking, twitter, tapatalk and some browsing all that per day was at least 7 days...i'm not sure how much time exactly because when i use the dock the battery stats seem to reset every time i close the lid or at random times....
Look at these stats. My usage was: downloaded 2 issues of my subscriptions on zinio, downloaded tonights breaking bad episode off torrents, saw a few youtube videos (about two 5-7 min vids), facebooked a good half hour, read half my issue of XXL magazine while sitting on the crapper and while waiting for my ribs to cook for a total of about 45 minutes of reading, + making about 6-7 benchmarks test on antututu to play around with set cpu (all but 2 tests were on performance modem the rest were on balanced), and your requested 30 mins of non stop browsing which consisted of looking for a wallpaper and browsing on ebay, all that in 3:26 hours and i got 26% battery drain, brightness was at about 30%, and this is what i consider it to be HEAVY use as screen on time is 1:56h.
Usage before your 30 mins of browsing
after your 30 mins of non-stop browsing:
So about 8% drop in 30 minutes of browsing and this is including 24 wallapers i downloaded from google images.
P.S. I'm rooted, not unlocked and i'm not debloated as i,m waiting for JB to really start playing around with the pad
mine would drop about 10% every 30 minutes watching videos - netflix or local.
my note, however, droped 25% after 3.75 hours of straight usage. this was with 3 episodes of The Unit, drawing, web surfing, and streaming netflix. i had to do all this while my daughter played around at monkey joe's.
all the reviews i've seen show the that the infinity gets 8hrs at 50% brightness. all my usage on both infinities and the gnote were all under 20% with headphones.
With dock, I am able to get 10 hours of straight use (non stop) playing various games. Played Angry Birds, Dead Trigger, ShadowGun, Amazing Alex, Drisk, etc. No wifi was on. I get about 6.5 hours on tablet alone.

It's a joke. All the ignorant ipeople always say android gets horrible battery life on the tech forums I go to. I find it funny that my tablet actually does get bad battery life. Then again, I never use powersaver mode so I guess its fine.
le rustle face
Thanks all for taking time to post a reply.
So I guess what I experienced with 2 units were indeed what it is. For some, perhaps many, infinity's battery life may be enough but unfortunately for my use it was just too short. Video play time or ebook reading time were totally fine. Its when we use browser, the jump to 20%/hr drain i.e. mere 5 hours of battery life with tablet alone. This won't last me a whole day. Sure dock would give extra power, but I got Macbook Air so if I want to carry actual laptop, I would actually do so. One reason I have been purchasing different tablet is mainly the use as tablet.
I don't know if it is fixable by firmware, but Samsung certainly does seem to achieve pretty similar battery life whether using browser or not, so I wonder it is something at the software level that ASUS is missing.
But I really appreciate all for answering this question.
Thanks
I too spent a considerable amount of time researching this as I thought my unit may have been defective. Long answer short it gets about 5 hours if you're web browsing even with low brightness.
I'm hoping a software patch can improve it at least somewhat, as having the WIFI on seems to drain the battery excessively compared with it off.

Yeah definitely that's what threw me off. We all talk about/assume higher pixel density thus more battery drain, which made sense but infinity's battery life with book reading weren't bad at all. It's the WIFI, which is very strange.
Hi
The Wi-Fi usage seems very high on these. No way should the Wi-Fi be using more power than the screen, certainly doesn't on my HTC One X, which due to laws and regulation will be transmitting with the same power as the TF700, but the screen will be using a lot less power than the TF700 as it's smaller so needs less back-light, so if anything Wi-Fi would be an even bigger percentage on my phone compared to the TF700, but rarely is Wi-Fi a quarter of the screen use, often much less.
Unless that Wi-Fi is doubling up as a small microwave oven, power usage should be quite a small percentage, so either the TF700 is mis-reporting Wi-Fi usage, or their is a fault (software/hardware?) with the Wi-Fi card.
Regards
Phil
no , we can not
I think we can not , it is too fake to say the battery would last up to 9.5 hrs.....
The wifi indeed has some problems, which would comsume more than half of the battery life.
Maybe.... asus intends to increase the wifi power to improve the performance!

Well many on this forum says its miscalculating, which may partly true but not entirely because as Battery drain was my concern on this system I did multiple trial and basically WIFI on with active browsing crank up the drainage to 20%/hr from 10%/hr without browser i.e. WIFI on but just reading ebook. So WIFI is truly consuming battery.
On my Galaxy Note 10.1, whether actively browsing or not the battery drain still remains 8-9%/hr. So yes. WIFI may consume more power but should not be twice... unless WIFI unit ASUS using is some weird one.
The storage brand and Wifi units are usually something most companies don't put on their specifications so hard to tell whether ASUS tried to use really cheap ones there to keep the paper specs great, yet functionally not meeting up the expectations. Or ASUS may simply have yet to catch up software people. Whether truth or not I heard Samsung hired quite few programmers relatively recently. And compared to my old Galaxy Tab 10.1, I definitely see marked stability/smoothness improvement on the Galaxy note 10.1 which also uses ICS just like transformer infinity.
The most interesting comparison for infinity would probably be though Xperia S tablet. Because that one also uses 1GB RAM, and Tegra 3 (inferior to one in infinity) and runs ICS. So if ICS there is as stable as Galaxy Note, at least we know its not memory, its not tegra architecture. Though storage will still remain as potential source.
But going back to the subject, battery life on infinity on the contrary to some here stayting dock providing extra battery, I find not great. Even with docking station, it either barely matches up with that of Galaxy Note 10.1 tablet alone or perhaps less especially if you play games.

I think in the TF700 they are using a Broadcom SoC for Wi-Fi, what ever it is though, drivers will be provided and it isn't much different to plugging in a Wi-Fi stick to a USB port. Perhaps they have configured it wrongly or there is a hardware error or software reporting error with the Wi-Fi. I can understand why people say it is a software reporting error as most people acknowledge it should never be that high as a percentage of power use so don't believe the figures. If they are the correct figures for Wi-Fi usage then something is very wrong somewhere.
Regards

I've been having the same problem. Wifi really does seem to drain my tablet too. I usually turn it off as I use juice defender and it helps immensely but it is kind of ridiculous for wifi to eat so much, especially when I want to start using the internet.
So as most of us already know that the WIFI when it is actively in use e.g. browsing, it drains a lot of power. Essentially, the battery consumption doubles when when actively browsing in comparison to the playing local video (~20%/hr to ~10%/hr). This does not happen on any other device I have used in the past.

In fact the WiFi is so cranked up on these baby's (same as for Primes) that it uses as much or more battery than the screen, and it's a pretty hungry screen! I wondered why they kept the WiFi pushed so hard on the Infinity, was it that Asus wanted to show just how great it could be (and other than no 5 ghz. radio, it is really quite good - I get roughly 4 times the throughput I had with the Prime, and twice what the TF101 could deliver) or was it just leftover coding from the Prime?

Not sure if this is true, but make sense if the latter is true. I wonder if there is anyway to turn down the power supply to the WIFI unit because I like my infinity with ANR pretty much now gone, beautiful screen, not real IO issue (for practical use), my only complain is actually battery consumption of tablet alone when actively browsing. So if this can be fixed, it would be phenomenal news for me.
I personally don't know. But anytime you have radios on, there is going to be additional battery drain. Not saying Infinity's isn't excessive.
You could try using the Power Save mode.
Unless I have the screen on, when the WiFi is turned, I can go all day This is just checking email, IMs, little web, and so forth. I do have a C8 release.

It's definitely true the WIFI component should drain battery; however, I think in infinity it is excessive when compared to any other tablet. And you are absolutely right that just having it on does not drain much but when actively browsing it does. The easy way to notice this is, if you watch video (local) the tablet alone can last up to 9 hours i.e. 10-12% per hour battery drain; however, as soon as you start active browsing not even streaming but simply surfing web it becomes ~20% per hour drain.
Sometimes antenna like devices can increase its signal gain based on how much power you supply to it. So the other guys post made sense to me in theory at least.
Right, I'm having issues with wifi on my Cromi-X 4.6 TF700. Battery drain is usually over 90% on wifi, and signal seems very low even when just a few meters from the accesspoint. What really pisses me of, is that I get neighboors wifi's at about the same signallevel, some of them on the other side of the street, while i'm getting a poor signal from my Apple airport express is sitting just a hands reach away from my tabel. I have tried moving the accesspoint, and also used a old d-link gameloung router to see if that helped, but signal strenght and battery drain seems to be about the same.
Since I'm seeing neightboors wifi, I somewhat doubth there's and actuall hardware issue. I have tried moving channels on the accesspoint, but that seems to have minimal impact.
Any advice on a good accesspoint that seems to work really well with the TF700?

I don't think it's actually the WiFI draining the battery more like you have lots of active apps using wifi when the machine is sleeping thus wifi is kept on. Download WakeLock Detector from google play to see what is keeping the device awake over a period of time.
Also try wifi analyser as well and see which channel it recommends. Wifi channels get pretty congested these days and it could be as simple as that.

Wakelock downloaded, will see what that tells me. I have tried changing the channel, but it has no or little effect. Just from my small neighboorhood I can see 10+ Wifi's from my livingroom, so yeah it's congested alright.
Am I right in beliving that power consumption goes up when signal levels drop?

Yeah but try wifi analyser it maps out your neighbourhood by channel and will show you.
Yes if it is having to work harder to stay connected then you coukd see power cosumption go up. Try wifi fixer from the play store as well. I use it on my prime and it works wonders as that has a much weaker signal.
Have been running wakelock for about 14 hours now, all triggers are at 1% so that seems okay. Google play music seems chatty, otherwise not much. How much battery drain % does the wifi normally show? I use my tablet for surfing, forum and mail only, so wifi is running constantly on use.

Much more than what is realistic - I believe the numbers that Asus uses there are simply wrong.
