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?

Hi,
just got my brand new Transformer Infinity today and I'm pretty disappointed with battery life - without dock it lasts something between 5 and 6 hours while watching youtube and browsing web and that's not much more than my HTC One X. I found out that wifi drains more battery than the screen - 40%, which is pretty weird, because I'm sitting right next to the router and wifi signal is always stronger than -50dB. Have someone experienced something similar?

Is there a way to check if it's miss calculated or if there is something wrong with wifi module? And if it's actually miss calculated, shouldn't Asus repair it to make sure it is calculated correctly?
your argument might have more merit if you did a test with the wifi always on for a period of time vs without it on.

Since it might be miscalculated that could be wrong. Try watching a movie with another one of similar length without wifi. Afterwards compare battery percentage.
The battery needs a few charge and discharge cycles before you will start to see more meaningful reports. Don't go around and unnerve people by posting about battery life when you cannot possible say anything about that particular issue right now. Let it settle in for a bit. Please.

No, it's not. Li-Ion batteries have hysteresis as well, and the circuitry needs some start and end points to calibrate itself. I would agree that in some cases, like in my SGS2, specific hardware is used that doesn't need as much info as other pieces do, but generally speaking, you can't expect full potential out of the box.
Posted for reference. You can keep believing in your myth busting capabilities; I do not have the illusion I can convince you otherwise.

I agree. As an SGS2 owner myself, I know that when a battery is first used, or removed and put back in, it takes the device a few cycles to properly calibrate the battery gauge to have accurate results. I imagine this is the norm across other devices as well.

Never experienced anything like that since Li-ion batteries came into production.
Btw, just did video tests with wifi on and off, there is almost no difference in battery usage (about 15% per hour with brightness about 50% and IPS+ off), so it seems the battery readings are wrong.
Also I found out today, that auto brightness does not work - stays at maximum level if you go into dark room from bright place forever, exactly the same problem someone experiences with earlier Transformer models. Does auto brightness work OK on your Infinity?

My specimen does the same. Brightness doesn't go down when I turn off the light in the room, and it stays at the relatively high level it was at. So that currently makes three of us.
Using auto brightness on mine now. Seems fine. Regarding the battery usage, i have wlan at. 30% usage after alot of downloading.

Apart from the physical characteristics of the batteries discussed above, it is a problem I have encountered in numerous Android devices - the stock battery stats are miscalculated in so many ways, we won't even have enough time to name them all (I remember users panicking about the dialer "draining" the battery in numerous threads, while in most cases it was only the stat issue showing the dialer using most of the battery after making/answering an initial call).
For some different measures, try different apps from Google Play, like Badass battery for example: https://play.google.com/store/apps/details?id=com.gsamlabs.bbm
According to the review from Taiwan, the Infinity could watch youtube movies for almost 7 hours. The brightness was set to max, volume was set to 50%, using wifi to connect to internet.

Engadget said they got about 9:30 out of the thing. 14:43 with the dock attached. That's looping a 720p video with wifi on, and the screen cranked to 50%. I think with normal usage, you can crank out a good amount of time. You just have to find that sweet spot with battery usage. I know I'm still working that out on my Bionic...but I've gotten that to last all day lately.

After one week of usage mine lasts about 9 hours while idling with 50% brightness, about 4-6 hours while watching youtube or browsing and about 3 hours while watching videos or gaming at 100% brightness and IPS+ on. Right now battery is at 66% after 1:48 of youtube and browsing with about 35% brightness, Badass Battery estimation - 3:06 left. What is battery life on your Infinity?
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

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.

How long have you been able to extend the life of your battery per charge? What type of settings do you have your tablet setup as? What apps do you rely on for system stats. I play a lot of heavy graphic games like Modern Combat 3 other Gameloft/Tegra3 games. Titles that shows off the power of our tablets. I also love to stream movies/shows and YouTube.
So far the shortest life span has been about 4 hours on heavy gaming/light browsing/and light streaming for my use.
How long has yours been lasting you? (I would love to see pics from battery stats)
Here is mine this is the longest so far...

Update: some of you including myself initially saw that the speeds would hang on 1500MHz or 1600MHz in my case. Which would drain our devices rather quickly. If your rooted, the way I fixed the issue of it hanging at 1600MHz was use Setcpu. Set it for Ondemand. Adjust it to Max:760MHz Min:102. It worked!! It stayed within those setting. You can now set it to your specs. Sometimes the system overrides your settings to accomplish a task that you are doing, but still much improved.

Last night the battery dropped to 37% in just about 4 hours then it took 2 hours to drop below 30%.
I dunno why.
It is difficult for me to get an accurate reading as I put in on the dock on and off all day. With the dock I get a full day of constant use. I don't mind charging it every night. As long as it gets me through the day I am happy.
I'm hoping this won't get moved to Q&A so we'll get more responses.
I'm getting about 5 hours of screen on time at balanced with brightness 1/3 of the way up. Mostly browsing the internet with wifi on the whole time, Bluetooth off, GPS on. This is from 100% charge to 0%. Seems low, tried a cold reboot it didn't improve. Maybe improving slowly over time. Currently showing exactly 50% with 2 hours 42 minutes screen on time.

So ever since I discharged it, until it shuts itself down. Charged it from %0 to %100 then used Battery Calibration app (Root needed) to reset battery stats. Now it seems to be lasting longer. Used to get on average 4 hours before that now 12 hours plus.

Erratic battery life
In balanced mode, I have GPS and Bluetooth off, brightness at about 40% (auto brightness is off), wifi off about half the time, keep apps running to a minimum and tend to use the TF700 in the same manner every day. Battery life still varies significantly and 6-6.5 hours is typical although I did get about eight hours one time. Wide swings in battery life are common. If I do play a game, it's usually a simple arcade game and rarely for more than 30 minutes. The rest of the time is spent reading or on the web. A Kindle Fire lasted longer doing the very same things with the wifi on all the time.and screen brightness at a higher level.
Screen flicker in balanced and power savings mode is pronounced from the auto-dim/contrast feature and not something I would expect from a tablet at this price. If it's supposed to save power, it isn't working.
The drop in battery power isn't consistent and while wifi is always at the top of the list followed by the display, I've seen battery readings slowly and steadily decrease and then suddenly plummet without warning. At this point, if the battery reading is 20-30%, I can't take the TF700 anywhere without charging it first because the remaining battery power won't last very long. Battery power seems to drop like a rock at 25% and below.
The tablet is pretty close to ideal except for the battery and, given a choice, I would prefer a thicker and heavier tablet with a more powerful battery over a thin tablet. I'd be ok with eight hours of reliable battery life with wifi but it has to be available in one long session and without screen flickering. A tablet where eight hours of battery life is intermittently spread across three days doesn't work for me.

The reason for the low battery is this; Asus did not put a larger battery in Infinity compared to Prime.
Both devices have the exact same battery, but since Infinity runs at a higher clock speed and has a higher resolution screen, it drains the battery much much faster.
You can't really fix this with software. You can however lower the voltage with a custom kernel, making slightly improvement....but that'll also make the device unstable.

Definitely the higher resolution screen plays a major role. Along with a faster Tegra 3 Processor.

I thought Jelly Bean was supposed to help extend the battery life.... "slightly".... by running processes differently...
I know it should increase graphics benchmarks a little...
Did I translate my readings incorrectly?
if i use it without the keyboard dock, i would get more battery life than my mac book air. but if i watch hd YouTube video or movies on it i will have more than twice the battery life then the macbook air

My battery life feels like it's too little, I've been wondering if I have a bad battery. I get about 4 hours of use but even with that, the battery only lasts a day, discharging 8 to10 % per hour while asleep. This is with minimal usage, mostly email, web and some photo work. It's like my smartphone which sits on the charger every night, except I never charge the TF700 overnight.
If I use the dock I get easy a full day with more than normal use. Fact is I don't think I could be using it more than 4 or 5 hours a day, just seems physically impossible. I've shut down all sync and wifi functions, no gps and nothing running in the background.
I'm gonna try the full discharge and 100% charge to see if that helps. My subjective opinion is that I'm getting about half the battery life as my TF101.

What is the battery calibration app your referring to? Also I think important part is screen on time.

Cool Tool - system stats:

I love this app! You can set it as a widget to keep an eye on your system from CPU, Processing speed, battery temp. I use it to keep an eye on Processing speed to make sure it's not acting up. When I first used Cool Tool I realized that for some reason I was constantly hitting 1600MHz under just normal browsing and viewing XDA!! Like it kept getting stuck. Which would explain why my battery only lasted 4 hours. After adjusting using Setcpu and Ezoverclock it's top off at 1400MHz Min of 102MHz and I've gotten better results and it no longer lingers at 1600 MHz

FWIW while my battery doesn't last long with the screen on, it doesn't drain much while asleep. I'm at all default settings, wifi always on, and I just picked up my Infinity 11 hours off the charger at 96% battery.
~~ how long is a string ? lol .....

Hello, .......
Edit: Forgot to mention that I discharged it to %0 until tablets shutdown on its own. I then charged to %100 and used Battery Calibration app (Root required) to calibrate my battery. Now getting 12hrs and more with the settings mentioned above.

Hiya JJ* .......... great post !
IMHO.... this question of 'battery life' is more like 'how long is a string?' question .....< sorry for this pun>
I am glad JJ* mentioned that the BATTERY NEEDS TO ME FULLY DISCHARGED ....
This is ONE VERY IMPORTANT and a KEY STEP.....
few yrs ago; when i had a working life <lol now am retired dude and lovin it> ...i happen to get assigned to do lots of work on "BATTERY LIFE" for CMOS & NORMAL POWER use in laptops (sorry cannt do mfgr;s names etc) ...........
I found that ( discharge is THE MOST CIRITICAL STEP ) is keepin that battery - life and reduce 'discharge rate'.....< providing all other usage factors were kept even/equal>
Another tip I found usefull -
Uninstall / Shut down any "APPS" that you dont use often - or hardly use
SHUT DOWN non -needed running apps >>hit TaskManager often and shut off RUNNING APPS ( i even shut down things like GSTORE etc etc ) .. and often amased how much differance it makes ..
so I will be posting my status and pictures soon ... to help towards some 'benchmarks' soon...
on average - I dont need charging untill OVERNIGHT - and mine is used 12-16hrs a day ( with dock though )
There is a 'sticky topic' on BATTERY saving tips ... on this forum

With this tool it's "nice" to see that my device is always running at 1500 MHz while surfing the web or reading in XDA/Tapatalk.
So the battery drains very fast here -. - The keyboard dock can't load the Pad while using it !!!
What could happen to my Device? Broken CPU or an App which is fail?!
Help me please guys

Are you rooted? If so use setcpu and change the max to something smaller then 1500MHz try 1300MHz and see if it changes. You may just need to get it unstuck. Same thing happened to me and after changing the value it now cycles normally from min/max
As far as your Dock. I'm not quite sure what you're saying. What is it doing when you connect the dock? Are you able to type with it? Is your settings for the dock correct?
In order for the dock to function correctly the default keyboard should be the Asus Keyboard under Settings/Language & input/Keyboard and input method/Default/Asus Keyboard

Speaking of the dock, I really think the TF101 did a better job utilizing the extra battery. On the TF101 the dock battery charged the tablet battery as long as they were connected. This meant I could use the dock like a cover and when I get to where I'm going the tablet is at 100%. I use it down to 80 or 90% and when I get to my next stop it's at 100% again. The TF101 dock never discharges farther than 3% but it keeps the tablet at 100% all the time it can.
My TF700 with dock lets the tab get down to around 76% before it even starts charging. If I take it out after driving for an hour it will still be discharged the same as if it wasn't connected. In addition to this behaviour it also seems like the dock discharges itself rather rapidly. At times I watch the tablet and the dock both discharge at the same time. This never happened with the TF101.
I should add: I'm using a stock TF201 dock (99$ BB score). Don't know if the ones badged TF700 work any different.

Mine isn't on 1500 always but its there a lot while browsing. Basically anytime chrome is doing anything, even now typing this. When its just idly displaying a page that's already rendered it'll drop down to 475 then 102 until I scroll. Is this normal?

Yes its normal. It does its best to optimize it's cores for the smoothest experience. Although with the Infinity and ICS it gets confused at times since its not optimized like it should. Jelly bean project butter is suppose to eliminate and optimize our power house tablet like its doing with the Nexus 7 running JB. Cant wait for it to drop!

Hi guys, i think the title is self explainatory. According to battery stats my wifi uses 86% of my battery while my screen only uses 7%. Ive also read that a lot of people have the same issue. Has any fix come up lately that corrects this?
I think just the battery stats are displaying that wrong.
For me it showed that too but when my tablet was on standby with wifi on it barely drained any battery (~0,1 %/ hour).
I am now on jb (cm10 alpha) and wifi doesnt evenshow up any more on battery stats any more.

Well I'm sure its killing my battery. When wifi isn't on and im watching video's or playing games, battery drain is great, roughly about1% every 5 minutes. When wifi is on, it loses roughly 5% every 5 minutes. A very noticeable change

So, with wifi on, you go dead in 100 minutes?
If that's the case, there is definitely something wrong with your pad. I've always got my wifi on, and unplug it in the morning. By the evening when I plug back in I am rarely under 15%.

You may want to read more carefully before busting someone's balls...
He said that with wifi on, it goes down 5% every 5 minutes.
5%/5 minutes = 1%/1 minute = 100%/ 100 minutes.

Principal: Mr. Madison, what you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.
Billy Madison: Okay, a simple "wrong" would've done just fine.
From what I can tell, the battery screen isn't displaying the actual drainage, but in fact shows the distribution of the drainage over the running processes.
(Because there is no way my screen is draining 54% of my actual battery charge whilst set to power saving 10% brightness... which it has been on for 38 hours so far, and it's still on 90%.)
WiFi 99% doesn't mean it's draining a whole lot of your battery in one go. It just means that, out of all the prcesses currently using battery, the WiFi uses 99% of the totally used battery. This may still be 2% in half an hour (I'm not quite certain on the rates), but of that 2%, 99% is the WiFi.
Doesn't mean the thing isn't completely silly. Mine right now says "Screen 54, Idle 23, Media 11, Mxplayer 9, System 3, Os 2" Which, unless both my brain and my calculator are wrong, is 102%....
