"12 hour battery life playing 720p video"

[rsarno]

If it can hit 12, or even 10hrs of straight video play ... does that mean "real world" use would be much, much higher?

If i use a tablet anything like i use my laptop, or cell phone, it will spend half its battery life sitting in standby.

What can be expected under such conditions? Anyone had theirs for a few days and can give some insight?

Thanks

I found nothing lasts as long as it says so I would give it 5-6 hours if that.

You missed the point of my question. It says 12hrs with constant video usage. Even if its realistically half that, so 6hrs.

does that mean 3x or 4x that much if you dont use it for constant video playing?

Doubt it will, I'm getting about 7 to 8 hours of heavy Web surfing before battery dies on normal mode which is not bad. Average couple of hours more with the ipad2.

Has anyone tried putting it in power saver mode? That is what they got their 12 hrs of video playback from. It under clocks the quad cores and uses the companion core more. should make a big difference. Mine comes in tomorrow so i will try it.

Here is Engadget's review.

Yes, wow. Pity the Engadget editor who had to babysit this thing while it ran unplugged, looping through our battery drain test for hours and hours. ASUS says the Prime's 22Wh pack should last a maximum of 12 hours without the dock and indeed, it squeezed out an impressive 10 hours and 17 minutes in our battery rundown test, which involves looping a video with the brightness fixed at 50 percent and WiFi on but not connected. That's a scant nine minutes short of what the iPad 2 accomplished in the same test, a difference that could just as well swing the other way should we test these two a second time. This was also running in standard power mode -- upshifting to economy mode likely would have delivered an even more longevous result.

ASUS Eee Pad Transformer Prime review -- Engadget

10:17 of battery time and with dock 16:34, I'm totally cool with that. My ipad 2 battery life lasted forever. I would go days between charging, with low to medium usage.

I know this review is not real life but a review none-the-less.

to answer my own question I am running my own test. I installed Battery Left .. not optimized for tablets but I like the method of calculation. fully charged then recalibrated battery left.

I'm unplugged and using the tablet somewhat lighter than usual, nut I'm at 91% still.

at this rate BL is showing a full life per charge of 148hrs

which will obviously change up or down, but this is initially impressive.

ps, I do surfing + emails + apps . typically no movie watching.

Based on what I've been able to get (see http:// http://androidforums.com/asus-eee-pad-transformer-prime/474039-battery-life.html )

It seems the stand-by stamina is really good.
