How long is the Windows 8 tablet standby time?

        Apple iPad has a big bright spot when it comes out, and the standby time is up to 10 hours.
10 hours, which made us tears in the notebook, so I bought the experience.
The second year, the Apple iPad 2 came out, the CPU performance was doubled, and the standby time was still 10 hours.
So, tears again, this purchase experience.
However, the iPad is a game machine for me, and it is also an e-book. It is unreliable for the office. After all, you think that the browser must support third-party. Open QQ, MS, and MSN on iPad and iPhone to open Word, Excel, Onenote, and browser work? I am afraid it is a very painful experience. At this point, some other ideas can go to "Waiting for Win8 books, I always wanted to throw away the iPad."
Well, now, Windows8 came to us, although it is still in its infancy, it has just reached the Beta stage, but we have already seen it at the BUILD conference, not only Win8 supports Intel, AMD's x86 architecture CPU/APU, even ARM The Win8 tablet with a single-chip architecture is also here.

So, what about standby time? Windows 8 legend is even better than Win7. Is the low power consumption real?
Okay, I received a stupid message from a foreign friend to the soft media: Samsung's Win8 tablet, standby time of about 5 hours, ARM architecture can reach 8-9 hours before and after (but here) NVIDIA's live demonstration of the high-end ARM tablet standby time is similar to that of Samsung.
How?
Not bad? !
The results are very good, after all, don't forget the amazingly high configuration of Samsung's tablet. However, Samsung has not admitted that it is a tablet (Samsung is too embarrassed?), Samsung has always called it PC.
Windows 8 Beta development has begun. In the process of RC and RTM, Win8 will have great changes. Let's look forward to it.
