I have used this tablet for 2 days now and almost everything works perfect (thanks to latest ota) but there's one thing that is bothering me. Battery life. I had ipad 3 for 2 months but I finally sold it and bought the infinity. Now I know ios sucks on phones AND tablets. But the battery life was amazing. I could use it to browse and for games for 9 hours at least. But on the infinity I am lucky if I get 4 hours browsing. 4 hours sucks on a tablet. But I think that wifi is the problem. I have added 2 pictures were you can see I used the tablet for 1 hour last night then I used it for almost 3 more hours today. Now the battery is at 10%. But I was wondering why the battery uses 62%? On my galaxy nexus wifi is using 5%.
Have I got a faulty unit or is it like this for everyone? If so please let me know fast so I can send it back before it's too late.
Somethings not right there. Tests/reviews done by some major outlets (thinking PC World or Engadget) reported 9 hours of video play over wifi with screen at 50% brightness. iOS has always had good battery life due to their stict contols over the OS, but you should be seeing more then 4 hours. Hell I was at 40% and played WindUp Knight for hours straight last night which takes up much more battery then a movie. I usually don't suggest using task managers, but there is one built in by asus, I'd use it and see if you can kill some processes. Also be mindful which profile is being used. I stick to balanced most of the time and switch to low when the battery starts getting low (24%ish)
http://www.engadget.com/2012/06/25/asus-transformer-pad-infinity-tf700-review/
The TF700 packs a 25Wh battery rated for up to nine and a half hours of runtime. Indeed, it lasted nine hours and 25 in our battery rundown test, which involves looping a video with WiFi on and the brightness fixed at 50 percent.

Thanks for the reply. I am always on Balanced and i am seeing over 20% down in an hour. Maybe i have a faulty unit?
I wouldn't be so sure. I was playing nova 3 on performance mode though.

Exactly, it all depends on what your doing OP. The movie scenerio in the review doesnt take much juice in that it uses the low power single core. I don't know for sure, but web browsing may require all 4 cores to kick in depending on exactly what your doing. Regardless, your wifi being a big consumer is easy to deal with. Somewhere in the settings is an option that automatically turns wifi off when screen is off.

Well, all i was doing was using chrome... I think it's pretty bad when i cant browse for more then 4 hours on a tablet. I thought it had to do something with WiFi since its using over 62%. I did the same test with my nexus where i i just used chrome and when i looked in battery , wifi only used 10%. Maybe there is a bug with wifi?
Try Battery HD for some averages/estimates.
I tend to get about 9+ hrs of reading, balanced mode, WiFi off, and about 7 hrs of browsing over WiFi (undocked, dock charges me about 2/3 full), but it all drops down drastically for gaming, which is about 4 hrs you mentioned.
If you get 4 hrs of pure browsing, I'd consider re-flashing, wiping data and - if these don't help - returning your device.
Chief Geek's point has much merit, and you could always look at (for example) GreenPower or some other time-/screen-based toggler. They do pretty well, and you do not even lose out anything except direct push functionality. (Does it really matter for 99.9% of mail when it comes in once every 15 or 30 minutes? When it does (when you're buying a house or something), shut down the toggler for the time being and cope with some battery drain, then when the situation has resolved, enable it again.
And try using BetterBatterStats for your statistics -- the main battery stat app Android offers has some quirks to prevent meaningful interpretations of many scenarios. Let that get a few charging/discharging cycles and then look at the stats.
So battery hd tells me I should get 8 hours of browsing and 9 for video playback. Will do another test tomorrow with screen on whole time and see how long it will last watching videos. Also battery hd tells me I can play 3d games for only 2 hours. Eh

Remember that these are just averages for your device, at least in the beginning.
If you mistreated your battery upon receiving it, it can kill battery life. You are suppose to plug in your asus tablet for at least 8 hours (well beyond the tablet would say the battery is 100%) the first time you get it. This is sound advice for any new Lithium Ion Battery.
Then you can start using it. Letting the battery die at 0% also decrease the life of the Li-Ion battery every time it happens (ignore old sites that say you should do a full discharge cycle every 2 weeks, that was for old Nickel Cadmium batteries).
Juice Defender is typically a phone app but you can run it as well to detect if any background processes are eating up your battery life.
I get almost 10 hours on my TF700 with moderate usage (mix of browsing, video playback, reading, etc.).

All correct -- there is a lot of disinformation going on with batteries (especially regarding the charging cycles, although a single, long, full charge and then draining to zero charge actually helps calibrate the battery indication algorithms in the device). The optimum minimum charge level seems to be about 40% or so I've read.
Juice Defender and Greenpower toggle WiFi on either time- or location-based profiles, and that works on tablets as well. Recommended!
Your phone doesnt actually discharge a battery to zero. The thing with lithium batteries is they maintain voltage untill nearly the end. This is a very large benifit for modern devices. Once the voltage starts to drop the phones circuitry cuts it off and prevents it from powering on with the LVC circuit that checks the battery before allowing phone to power on then immeditately cuts it (first attempting a power down then all out power cut). This happens to protect the battery. So what the phone considers a dead battery is simply an exhausted battery ready for charge. If a lithium is actually dischardged completely it will damage the cell and prevent it from taking a charge. The power being given to it is then converted to heat. The battery then ignites and very very bad things happen such as your house burning down. The point of all that is to point out that discharging your phone to "zero" isn't actually doing any damage past the normal wear and tear on the battery. I buy batteries that cost hundreds for some of my RC hobbies and have learned the hard way about how lithium batteries work. (bypassed LVC and ruined a $80 3S2P pack)

i have actually read that Li-Ion batteries can be used out of the box. Sp i turned on my infinity right away. I put the charger in, but i still used the tablet. It was about 25% when i got it out of the box. So what you're saying is that i have basically ****ed up the battery? If so, then i will return and get a new one. But i dont understand why most people say that you can usre a device with Li-Ion battery staright out of the box without needing to charge it first.

Nothing to add, technical and extensive, but fully correct, sir. I think we may have had a slight misunderstanding, however: my point was that discharging your phone to 'zero' (and as you rightfully point out, that is not an actual fully discharged battery state) is a required step in calibrating most device's algorithms (some devices, such as my SGS2 do not need this because of advanced hardware). I'd rather not fully discharge any Li-Ion batteries either.

A typical case of RTFM, an affliction I sometimes suffer from as well, as do most men. Hahaha! Do you think ASUS put it in the manual for laughs, or just to give you a few more hours of painful desire to use your device while you cannot, yet? Nah, it's there for a reason. Sometimes, though -- and again that's SGS2 experience -- just running a few battery cycles might make the readout correspond to the actual battery level again. You could at least give it a try, right?

I see the same picture here. Looking at the battery stats I see WIFI using >90% of the battery when surfing in balanced/50% backligt mode.
Hope they fix this.

I stopped by an AT&T corporate store to get a hands on with the Captivate. The salesperson there tried to tell me that the standby time on the device was 15 days if you kept apps from running by downloading an app killer. I asked if he really meant 15 days if no radios were running. He said "nope, 15 days is pretty easy".
Really, folks... what is reality here? Is it similar to other smartphones, where a day with moderate use is reasonable?
There is no way the phone will last 15 days in standby even with a good task killer. How can the sales rep tell you this if he only had the phone in store for 2 days?
That's a very good point... but he was very sure of his claim. I pulled out the "I'm very skeptical" response and walked away. Oh well, looks like once again, truth is in the internets somewhere, not in someone who should know such things.
Another element to this is whether an upgrade to 2.2 will increase battery life. I work away from any ability to charge and really need a phone to hold up all day.

Well, my N1 holds charge for about 1 day with moderate use. As soon as I play with the GPS and google's built in nav system I get maybe 4 hours worth of usage. Another issue I have with my N1 is that my car charger cannot keep up with the drain, so even plugged into the charger the battery percentage is decreasing. Sure hope the Captivate is better in that respect.
Froyo did increase battery life a bit but it is not earth shattering. The advantage of this phone is the larger capacity battery and hopefully a less power hungry samsung processor than the qualcom snapdragon.
I am sure within the next few days we will have some folks with more concrete consumption estimates.
i don't know... while the 15 day claim is a bit much, mine was fine with heavy usage all day yesterday on the half charge that it came with from AT&T... given that, i think that it should last 2-4 days easily with only light-moderate usage.
My battery lasts me all day. It's just marginally worse than my 3GS I think... My 3GS always had extra at the end whereas my Captivate seems to run out when I'm going to bed.
So... It lasts all day. That's really all that matters to me.
My battery has not been able to make it through the day. Don't know why yet. I have my email accounts set to 30 minute sync schedule, have Wi-Fi and bluetooth off. Don't know what is going on. Still researching. Will see how it goes for a week. Might be a bad battery.
i find that dark backgrounds help. Also keep unecessary things off and dl an app killa. I had a new captivate today at 10am and with its half charge and heavy usage it lasted me till 6
by heavy usage i mean constant surfing and dling shiz. I didnt use gps wifi or play a movie. also played that free mario game for bout an hour.
After about 11.5 - 12 hours of very light browsing (maybe like 1/2 hour 3g surfing, no calls, all apps killed with task killer every once in awhile) with Bluetooth and Wifi off I am at 68% left. This is with auto brightness.
I'd say if you don't do anything you might be able to get 3-4 days out of it. According to my battery stats 78% of all my battery usage has been the screen. Keep that thing off / or low brightness and you are going in the right direction.
i bet by standby att means the phone being not used and turned off for like 4 days lol

By dark, he means a background that has a lot of black in it. This is really helpful because the Super AMOLED screen on this phone turns off power to pixels that are black, so basically that part of the screen isn't using any power. A black background is almost like turning the screen off.

this, thanks for clarifying.
note: it further helps if you apply a static one.
I was able to listen to music for 6 hours at work, show off my phone (I only showed it directly to one co-worker - I had 5 other guys come to check it out after he told them about it lol!), did some light surfing, downloaded a few apps and generally fiddled around with the phone and ended up at 43% battery. Not great, but not terrible either. Screen was the big killer here. GPS and WiFi off except to test Layar.
We'll see if battery life improves, but it enough to make it through one day easily for me. Forget to charge it and it'll be flat early into the next day though. I'm a bit disappointed, considering benchmarks on the Galaxy S came up with nearly 8 hours of constant video playback. I think they had brightness at 50% and I kept setting mine to max to show off the screen and then forgetting to set it back, so that could be part of it. I was definitely expecting more though. I'm clearly not the most demanding user here, so I was hoping to potentially eek out two days of usage (just in case I forget to charge it).
One of the reasons I went with the Captivate instead of waiting for the Epic is that the form factor seems to be a bit more amenable to adding an extended battery. Hopefully we'll start to see some 2500mAh or even 3Ah batteries show up - even if it means getting a new backcover. THAT should just about do it

Also the Super AMOLED Screen sucks alot less Juice as well...
My friend has the Vibrant and has had it for about 4 days. He is a power-user like me, and he said with his task killer, he can run the phone for 2 days on a full charge. This is outstanding for a smart phone... I ordered my Captivate today, should be here on Wednesday so I'll also put this to the test!
better battery life is coming once devs hop aboard. Also, your phone will need training over the next few days so it can only get better from here for you. I also recommend just leaving brightness on auto detect. You wont have to play with it as much and forget it on super bright.
Some more tips:
idk if you guys like haptic feedback but i think its annoying as all hell. Turn it off to save an iota of battery.
Also tone responses for menu clicks? ANNOYINNGG turn that shiz off for a squirt of juice.
Lastly, unless you live by your email, turn sync off and only sync manually when ur curious about it.
I wonder about some of the widgets. I have Weather And Toggle Widget (which I prefer over Beautiful Widget), and have it set to update the weather every 30 minutes. Wonder if that's too often. The weather in Iowa can be very unpredictable and change quickly, but I'm inside all day so it doesn't really matter. I guess it's just eye-candy mostly.
I also wonder how WATW compares to BW in terms of battery consumption.
I turned haptic off (I agree, it was annoying). I turned the tones off, though I doubt that will affect battery life. I wish I could keep the tones for dialer and kill it for the keyboard.
EDIT: I keep reading about this idea that you train your battery (or device) to your usage, but I'm not sure that I understand/buy it. I could see perhaps something to do with the memory effect if these batteries are susceptible to it, but this idea of "training" it strikes me as very odd. Does Android have some kind of battery optimization algorithm that adjusts services based on your usage or something?
from what i understand, calculating battery life is like a guessing game. calibrating your device by letting it drain out and then fully charging it and draining it out again completely gives your phone an idea of just how long it can last on a single charge. Until you do a few cycles like this it will incorrectly display batter life percentage giving the user a false sense of security or panic. There may be more to it that has to do with the actual battery itself but idk the rest of the details.
and 30 min updates is a bit much lol. u should update like once a day and manually refresh if you need to know b4 u go out.
I'm getting very good battery life on my phone. As good as any iphone I've had and better than any of my windows mobile phones before that. I don't have any widgets constantly pulling down data though and only have my google account syncing contacts and calendars and an exchange account running.
I'd love to hear how people are finding the battery life on the Captivate, and what their usage patterns are. I don't have many apps on the phone to begin with, but on the train to work I can easily knock out a third of the battery just listening to music. While using the phone for five or ten minutes, I'll sometimes see the battery dop 2-3 percent!
For tomorrow, I'm going to try using the stock launcher instead of LauncherPro, no widgets. I got rid of the Android Central app just in case it was fetching data in the background. But my hopes aren't terribly high, I'm afraid.
I have rooted the phone, but the battery life was bad before rooting. Once rooted, I tried some apps like JuiceDefender, and there seemed to be no change.
If I continue having these problems, I may unroot and bring the phone to an AT&T store to see what they say. I've heard it mentioned that Samsung is sending out new batteries that are better than some current ones, but I don't know if that's true.
I'd love to hear any suggestions. I want to use my new phone, not worry about it all day!
I too have been getting very poor results. I have talked on the phone for less than 3 minutes, went to maybe 15 different website pages, one 3:00 youtube video, 10 minutes of GBC emulation gaming, and regular texting, and I'm at 10% with 8 hours. I've probably only used the phone for 30 minutes total today.
Smartphones always drain battery, if you want a phone that can be heavily used for like 4 or more days on one charge cycle, get a feature phone....the samsung captivate has given me the best battery time overall, against all my past smartphones.
I don't think it makes sense, though, that it should run out halfway through the day like mine is. My former devices were a feature phone and an iPod Touch. The feature phone lasted a week or so, and the iPod Touch with heavy heavy use lasted three days at least. So even if I had both pulling from the same battery source, and with light usage, shouldn't it last at least a full day?
Weird, I had wireless on almost all day, with push mail and doing tons of market downloading and I was only down to about 50% by early afternoon.
Seems about the same as my two year old HTC Touch Pro to me.
My battery is running fine too, even after streaming music from my house with subsonic, testing out a couple videos, messing with the gps, push email a bunch of app downloading, and a live wallpaper and i was still at 33% by the time I got home, even seems to be getting better.
"On the train to work..."
There's a bit of your problem, methinks. The 3G radio is burning a lot of power trying to connect to towers inside a metal box that moves to a new tower on a regular basis. Unless you need to get calls on the train, put it in Airplane mode during your commute.
Have you actually let the battery die completely yet?
My first battery burn-down, (starting with the charge on the battery as it was unboxed) I was showing zero percent battery for almost two hours before it actually shut itself off, moderate usage with WiFi on.
The next charge-up burn-down, it was showing zero percent about fifteen minutes before the end.
And the charge-up burn-down after that, it showed 0% about twenty seconds before it died.
See where I'm going here? The software needs to be calibrated at zero and 100, and it can't do that if you don't let it reach zero a few times. Once you're sure the meter is accurate, then you can start making informed conclusions about battery life.
And like I've posted elsewhere, you've got 'Newshiny-itus', which is proven to suck extra life out of a smartphone battery. And it's hard forcing your new toy to die...for one thing, if it's dead, you can't play with it. Tough it out, kill it. At least twice.
Well if you want to find truly terrible battery life try the EVO.
I had one for a month and that thing really ate the battery fast. The capti is stellar in comparison.

Yea I had one for two weeks and it was horrid. I would lose 6% just in standby time in between waking up and getting out the door to work in the morning!

I've had great results with the battery and I find it to be much better than my HD2. I watch quite a bit of youtube, text message a lot, and browse the web and the market on and off, not to mention all the time my wife plays solitaire, and I still have 30% battery at an uptime of 41:46. I don't use gps or live wallpapers, and I keep my display as low as possible, since it is still bright.
Bit better by the end of the day. 13 hours and 15 minutes

Definitely agree with the last part. I've been doing my best to kill it, but I don't want it to be dead. Been noticing the inaccuracy of the meter quite a bit, especially when it's charging, but I'm sure it'll get better over time.
Thanks for the informative replies! It hadn't occurred to me that the battery meter might be uncalibrated - I've been charging once it reached 10% or so. I'll try letting it die fully today.
One thing that seems to have helped, too, is the brightness settings. Turning OFF the "power saving" auto adjust ing brightness option allows the brightness to stay low, and a brightness control widget lets me set it lower than stock controls allow. I've seen some definite improbement from this alone!
These are Li-ion batteries, DO NOT let them die completely before charging.
Ok, so...is there a safer way to make sure the battery gets calibrated? I'm reading in a lot of places that Android phones fairly often misreport battery info unless calibrated.
The lowest I can get on battery status is 60% after a full days use. Admittedly I'm not a power user but I had my phone unplugged for 16 hrs and still had 95% I'd like to know what you have to do to get such low battery levels , start your car
All I've done today is listen to music for an hour (used 25%) and texted/browsed the web for perhaps two hours (another 5/% down.)
I read that LIons can be occasiomally discharged, since they have undercurrent protection circuits. One guide for Android phones suggested leaving the phone on until it shuts itself down, turning it on again, and then letting it shut itself down again. Then, with the phone off, charge fully. The guide said once a month or do is safe and beneficial. How does it sound?
Battery is good today. Been sending a few texts, checked email, facebook, and surfed these forums a bit. I'm at 2 hours with 98% battery left.
i hope the battery doesnt suck, i plan on getting this phone soon and want good batt life!!!

I agree with you, however, the phone's hardware will NOT let the battery completely die.
So I wouldn't worry about that all to much.
Basically though, Li-ion batteries are 'memory' free so they can be recharged on a whim partially.
They also prefer partial charges vs deep charges.
There are questions about this that I don't have answers for such as: When the phone displays 0% or shuts off due to low battery, how LOW is the battery?
Obviously the phone battery can't be dead dead, but it is low enough for the hardware to take precautions.
Anyway Li-ions will at max last 500 charges.. If you want it more than that, You're going to have to buy a new battery anyway. =)
I am very hesitating posting this but this is my theory of why there is a huge different battery drain between people. I have 2 droid charge, one belonged to my wife (this is the one I play with it all the time), the other belonged to my daughter and I never look at it until a week days ago when I want to set the record straight with the battery drain issue. Both using stock 1600mah samsung battery. I Odin pit file and factory GB 2.3.6 to both, then flashed Tweakstock. Installed battery defender app on both. I installed the same exact 15 apps (included Lookout). Screen brightness set to 75%. Everytime I used one phone I do the same to the other at the same time. For example: I opened browser at the same time, navigate to the same sites for the same about of time. I mad dummy phone call, I made calls to my two sons' phone and put the 2 charge next to my mouth and talk. So they are pretty much calibrate and 99.99% identical and usage. The results is one is last 10 times (my daughter phone) than my wife's phone. Now how the hell is such a huge huge different. Max time for my wife's phone is 9 hrs and my daughter is......2days. I have a test list to play with both for 1 hrs. So let say the charge is 100%, after I played with my usage list(1hrs), the battery went down to 90% which is 10% per hrs based on my usage list. I did the list again (another 1 hrs) and I see another drop of 10%. So I concluded that my list is pretty accurate for the % drop. If I exercise the list 3 times (total of 3 hrs), 10% each hrs so total usage is 30%. I project the rest. If I do the list 9 times, total would be 9hrs and I should have 10% left after 9hrs. Well, I applied this theory to both phones and the results are unbelievable. So I concluded that the components of the phone is different, possible the cpu, gpu chip from one phone is better than the other(hardware issue not software). That would explain why some people can Overclocking to 1500 and still stable and others only stable at 1100. Some can hit 3100 quadrant score and most only can hit 2200. Here are screen shots of my daughter phone(brightness setting and all the processes, with 13+ hrs and only 70% left. Her phone should last 13 x 3= 39 hrs with 10% left. That's more than 2 days). On my wife phone(the one with ****ty battery drain), I then installed immonsy kernel, then PBJ, then undervolting it, then Jucice defender etc... nothing help. The best I can get out of this thing is maybe 2-3 hrs more. So people don't feel bad if you see pictures with 1-2 days battery life and they are real.
Gotta be right because I get decent battery life on my charge and no matter what I do to help my wife with her phone it just plain sucks.
Overclocking a phone is very similar to overclocking a computer. Some people get lucky with their silicon and their CPUs can handle massive overclocks without breaking a sweat, while some have problems going even 100mhz over their stock ratings. With this said, most processors have very similar power draws at their stock frequencies, regardless of their OC capabilities. I don't think it's the processors fault of battery drain, and also I don't think there have been any hardware revisions.

Yes, the lucky people have their "better silicon chips" inside their Charges. So If you're not in that lucky group, try to tune your phone to get at least close to Samsung factory specs for your Charge which is 11 hrs talk time for normal usage. )

Maybe your wife is using her Charge more than your daughter. Try to keep sync off and screen brightness low for the charge that drains rapidly. Try using wifi or keep mobile data off when not in use (4g eats your battery).

No one will and no one does. Samsung 11hrs talk time is if you only talk on the phone the total time is 11 hrs. It may take you 2 or 3 days to add up the total talk time not in 1 shot.
11 hrs talk time, which translated into about 5 hrs of usage (talk, internet, facebook, text etc..). Talk on the phone doesn't burn that much of power. When you put the phone against your ear, the screen turn off automatically. So, yeh! 11hrs talk time is legit.

You did not read my post clearly. Both phones were put through the same test with the exact same setup. For normal use, my daughter have the brightness up to 75%, 4G, GPS on all the time, basically she never think about the battery. On the other hand, my wife phone with auto 4G off when she turn off the screen, GPS always off, ,manually syn for all internet apps, 15 sec screen timeout vs my daughter is 1 min....and she still has plenty of battery leftover before she goes to sleep @ 11pm. It's the silicon hardware that some luck phone(my daughter is one), that you don't have to do anything and the battery last forever...
The battery itself is a huge variable.

A simple test then is to switch batteries and run the test. I have 2 batteries, one 1600 stock and a 1500 one purcased but still. Both have rather poor lifetimes. I've also replaced my phone once with no change in battery lifetime.

Nope. test them all already. I have tried with third party and stock batteries with ALL available capacity 1600,1800, 3500 and 3600. The draw rates are the same for all. they also about 6 months old. The 1600 (about little over 1 year old) is in my phone, which I used to take these pictures.

I too had switch phone, but It's not a lucky one. I then bought another one for my daughter cause her phone broke and she got the lucky high quality silicon one and it's also a refurbish one, not even new. LOL!!

Your case, you may have a premium silicon phone and one ****ty battery, which is good, all you have to do is buy another bat. for $10.
Samsung in particular is guilty of this. They snuck in different hardware components with the WP7 Focus S without telling anyone and screwed up the Mango update rollout for Microsoft. It's up to Samsung to provide the proper drivers for their hardware.
Now with that in mind, for some reason updating to ICS on my HP Touchpad has eliminated my battery drain issue, so here's hoping the same will happen with the Charge.
Edit: And just as I said that, my Touchpad lost 20% of its charge overnight. Then it lost less than 1%/hour during the day. Sigh.

I think your first statement is correct, since I have 2 exact phone with exact SOFTWARE and one is 2 days on battery and the other is 8hrs. I hope it's software but since I did the test, I strongly believe this is hardware issue. If we still suspect software, maybe someone can download ICS and see if it still drain?

Like I said, ICS drains battery like crazy on my Touchpad. 20% overnight. A lot of Galaxy Nexus users seem to have battery issues as well. I read about a company called OpenMobile releasing a thin client that lets you install Android .apks in webOS and run Android apps in webOS cards. They've managed to port over the Dalvik VM with 95+% speed. It's pretty amazing if it works as advertised. The idea of having the battery life of webOS with the awesome apps on Android is quite exciting.
We have 2 Samusung batteries. One we get atleast 10 hours the other we are lucky to get 6 hours. That is on a stock software phone. On mine I just put Eclipse
on with the latest kernel and tweaks and I hit over 14 hours for the first time.
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?
Hello,
I'm new here and have a quest about my new tablet
I bought the Transformer Pad Infinit a few days ago and I think that I could use the battery for 9 hours more or less.
But my battery is extremely weak, I just use this 3 or 4 hours with the GPS off and bluetooth off too. The wi-fi is just on in the half of this time, and waht I do in this time is play some games and use the internet. I use the "Energy Economy" mode all this time and the light of the screen is in 20%.
I guess my battery is more weak than others... What can I do to "fix" it?
I would to say "thanks" for everyone, and I'm sorry by my english, I don't know english so well
The battery in your Infinity may be not charging to 100%.
I don't get 9 hours with moderate use...I see around 6 hours.
My wifi and GPS are always on and the screen is about 30%.
The batteries aren't supposed to have "memory" meaning: they should be able to be charged over and over from any discharge level back to a full charge.
There also might be something running in the background that is taking down your battery charge.
Have you browsed the battery saving tips in the stickies here in the TF700T forums?
Is your Infinity the LTE version by any chance?
Some info:

First: Thanks
I search in the internet and I found that the Li-Ion batteries have to charge arround 30%~50%. I do it much times.
I was using a animed wallpapers and I change it by a normal wallpapers. I guess this make some efecty
I search here in the forum too, things about the battery saving, I found somethings that can be helpful, but no "so beautiful"
I don't have the LTE version, I guess nobody have it, Asus is so stupid when we talk about "3G/4G"
I don't know why, but mysteriously, the tablet use about 600mb of RAM and also nothing is running, just the things of the systen.
I guess it's strange, maybe that interfere in the battery life no? But how can I "fix" it? SImply have notthing running and 600mb of RAM are in use.
Thanks again, and again: sorry by my english

That's OK. Unused RAM is wasted RAM, and unused RAM uses exactly the same amount of battery as used RAM, so no need to fix anything here. Interesting for battery use is CPU utilization by running processes.
I have to admit the battery life is not brilliant on this tablet. It very much depends on the usage, this wasn't really the case with previous LEAST powerful galaxy tab 8.9. Even during playing games it easily lasted 8-9 hours.
Worst infinity battery times observed ( balanced mode, brightens < 30% )
- playing hard core 3d games, like dead tigger, battery dead in 3-4 hours
- playing less intensive games, battery dead in 5-6 hours
- browsing battery dead in 7-8 hours.
- watching movies, battery dead in 8-9 hours.
so anything between 3-9 hours can be normal with infinity. I cannot even imaging battery life in performance mode, IPS+ full brightens
I was with fear, 'cause for a moment thought that my battery was the only one that is "not so beautiful" But I saw that is not a problem with my tablet and yes with this model.
I'm Brazilian, here the Asus is a perfect nothing. Here we have just the TF101 who comes with 1 year delayed. So I buy the tablet in other country and I don't have warrancy, if my battery was with some problem I don't know what I would.
Here if I call to Asus they would hit the phone in my face before I can say "Transformer"

Ummm...
So you ... own the Asus Infinity TF700T?...or the TF201?
...don't get hit in the face please!...especially with a phone...maybe a small phone wouldn't hurt a lot.
I hope your face doesn't get hit though...
God I love Google Translate... :laugh:
Asus very clearly says "Battery life tested under power saving mode, playing 720p video playback, Brightness:100nits, default volume with headphones." on their website. If you try something else, you'll get different results. Basic scientific fact.
Also, I can't stress this enough: Kill off all bloatware! No you don't need to root the tablet for it (most of it, anyway.) The more processes you run in the background, the more power they consume. Simple as that.
And WiFi EATS battery like you wouldn't believe. It's so horrible it's not even funny. The WiFi unit is very powerful, which is why it eats so much. So yes, using WiFi will eat your battery.
andoid uses RAM differently than Windows. Forget how it works there. Android reserves RAM for processes, even when they're not in use.
Could be the Google Location bug? there's info on that here somewhere too.
Go to settings --> Battery and see what uses the most percentage.
