Hello All,
does anybody noticed the increased power consumption after the last official update (3.2.1)? Below is my battery chart after just one day. The most interesting part is when I didn't used tablet in last couple of hours, as you can see no WiFi, screen, pad not awaken and... battery draining as hell. On detailed battery usage screen Android OS was on the top with 38% then WiFi 15% and screen 12%

Before update battery life was ok (My TF is early hardware, stock OS, no root etc.). After update I didn't changed anything, same configuration, no new software, updates etc. Just rebooting two times because tried to get rid of another 3.2.1 bug aka "mobile browser"
I appreciate that Asus is quick to pushing updates to TF, but this time they did it too fast.

Does anyone have a similar problem, or is it just my update went wrong?

Yeah really impressive, battery from 40% to 0 in just 16 hours of doing nothing .

But to satisfy your curiosity, I had around 7-8 hours of continuous use with WiFi and screen on.

You are going to want to charge your battery to 100 and use the battery calibration app in the market...called battery callibration. Do the instructions it tells you.

You might want to install CPU spy and see what is running in the background to drain your battery like that.

This is a real bug. Here's a screenshot I just took from my tablet. Tell me you don't see something strange with Android OS taking up 26% of the power.



That's 83% battery life left over 4 hours of me using it for about 30 minutes total.

You may want to observe the non-sleeping time using "cpuspy" from Markets. Quite revealing...

Can you see the actual apps or processes running with cpuspy? All I can see is a horizontal bar graph with percentages of different frequencies

You are right. No apps shown. But it shows a bar indicating the duration the cpu spent in deep sleep - this is useful for me.
