I let my fully charged TF700 play video until it went dead. I used power save mode, brightness was at 25% (which is extremely dim), speaker audio was set so it was barely audible, GPS, Bluetooth, and wifi were off, and no other apps running. Here are the results.

Time Battery
0:00 100%
1:00 90%
2:00 76%
3:00 65%
4:00 55%
5:00 44%
6:00 35%
7:00 25%
8:00 16%
9:00 6%
9:36 Tablet went dead.

I used different videos (all were lower resolution than 720p) and three diferent players. I'm not sure if the Asus battery life "spec" has wifi on or off for their movie test, but if they claim it's off, then the TF700 meets their spec. If they said wifi was on for the test, then their marketing department probably wrote the battery life spec.

I'm very surprised to see how nice and neat the battery life drops by roughly 10% per hour. I expected more variation since I used videos of different lengths and hardware and software playback at random.

Software playback and got that sort of battery? All my jelly.

The last I checked the official site stated no specific condition for tablet alone; however, with dock they said 14 hours and that condition was in the power saving mode & wifi on with video playback testing. In my experience, wifi on won't really affect much as long as you don't actively surf the net and I indeed see ~10%/hr drop with video play back with wifi on (but mine was in balanced mode).

The only thing I don't like about battery life in infinity is the WIFI on browsing battery life. Somehow as soon as we start browsing internet, the drain goes rapidly up to ~20%/hr. I don't know if they have some weird software setup so that browser continues to make wifi connection and drain battery, or browser uses so much CPU power, or wifi unit takes so much battery etc.

Hopefully the next coming update will adjust things so things aren't draining so quickly. Software updates should be able to fix these things so we can get optimum battery life, like what I experienced with the Prime

Here are the results of my testing - power saving mode, playing 720p video on constant loop with headphones plugged in, volume @ 40%, brightness set to 17%, wifi on with gmail running in the background - basically the same test asus uses to benchmark the battery life.

I tried to keep it on the entire time, but the tablet went to sleep for about 1hr 45m while I was out doing errands. Total run time for the tablet alone was about 9hr 40mins (discharges at ~10% / hr). After discharging to 1% I plugged it into the dock (201 dock labelled as 700 if I am not wrong).
This is where the graph says "charging". Tablet stays on another ~6hrs after being docked.

Screenshot attached because I can't post links yet.

Screen on time? Wi-fi on time? It doesn't look like you had wi-fi on since it isn't shown in the battery stats...
I am not sure why the guy above showed Galaxy Note battery life here... But Galaxy Note 10.1 does have amazing battery life. As I recall it didn't have WIFI category but you can see Internet category.

Any event since you seem to be interested in the result, I can tell you based on my 3 weeks of Note experience. It readily lasted 10+ hours with active internet browsing and playing games. With the same type of use, infinity can only last 5-6 hours primarily due to WIFI drain is ridiculously high on infinity (unfortunately).

Maps somehow drains my battery big time if I forget to force close it it will drain my battery while off! What is using Google maps like what's making it start naturally? I my gps is off obviously maybe twitter or something has some location service non stop

discharging

Hi, i'm just curious..when recharging it after a complete discharge does it matter if the tablet is recharged when its on or off?

Doesn't matter at all no :)

I can usually get around 2-3 days of life out of it, but I dont turn it off over night or anything. It'll have around 5-6 hours of onscreen time with wifi on. Wifi is by FAR the biggest battery killer in any android device. Dont know what it is, but compared to my old ipad and iphone, wifi just sucks the life out of these things.

My best tip for you is GreenPower free.

That app is awesome to control wifi power.
I have mine set to 2 mins on each 1 hour, so now it is actually the screen using the battery, instead of only the wifi :)

I also use it on my phone with the same results.

And of course root and CleanRom2.3 is awesome together with Clemsyn kernel :)

My battery life seems to be less than expected. I had the tf300 for a few weeks, but I returned it for the infinity. The battery life on that was at least double what it is on my infinity. I couldn't kill the battery in one day and I used it more than I do the infinity. WiFi wasn't the main culprit for eating battery like it is on this. I had WiFi set to never sleep on the tf300 just like I do on this. On the plus side, my infinity seems to charge pretty quickly. It went from about 40 percent to 98 percent in less than an hour. Maybe things will change after a few charging cycles, but I was to the impression that new batteries did not require conditioning.

Found a SERIOUS battery drain!

If you're using an USB Ethernet adapter, and set it to "Retain Ethernet connection during sleep", it DOESN'T TURN OFF. Even when you disconnect the USB adapter. The icons disappear, but it keeps running secretly, and doesn't show up in any battery monitor!

Mine suddenly went from draining in 2 weeks to eating both my tab and dock completely in less than a day for seemingly no reason. Figured out eventually I turned the USB adapter to always on to listen to the radio at work a week earlier. Turned it back off, and lo and behold, 2% drain in 3 days.

DO NOT LEAVE THIS ON.

(Yes, I also posted this in the General Sticky. Can't hurt to be mentioned more often.)
