[Asus  Eee Pad Transformer Prime] 131313:
I make it short:

Yeah another wifi/ battery thread. But the only one with an actual solution for pi poor battery life after 21 update. Some people reported it helped also with the sod.

Wifi sucks battery dead.

Some people let all sorts of juice sucking bat-control apps running to find out that stock app reading is not lying: The bloody wifi never turns off even set to do so in the settings and just kills the battery of the device.

If this is your workaround you owe me a thanks . If you are an Asus employee testing poor battery issue give me credits in the fixing OTA by repairing the 'never' settings:

Go to

settings, w-lan,advanced (click on the three dots in the upper right corner, there it is), keep_wifi_on_during_sleep:

Instead of setting it to 'never', set it to 'only when plugged in'.

Now put your machine in sleep, wake it after 30min or even much less and BOOOOOOM! here we go:

You will see in the battery settings, that your wifi just has stopped pausing. Depending on how long ago the battery cycle has started you will see two shorter bricks instead of a long one as before. While waking your machine concentrate on the battery icon and you will notice the wifi-icon popping up just a second after you have woken the screen.

Of course this works also with shorter breaks but I'm not sure what is the shortest interval. Longer sleep period opens the gap in between two wifi-sessions wider. So this makes the working proof easier visible for the eye.

Sort of really a shame that Asus, Google and Nvidia have hybrid, wrongly programmed and even forgotten settings in their setup. (see my thread about the multitasking of the HTC1X http://xdaforums.com/showthread.php?t=1599214 Maybe helps your multitasking issue.

But as we know, nobody is perfect .... except for xda!!:cool:

And then, many report, they don't have this problem at all. Very strange that not everybody is affected by this blind setting.

If this solution doesn't help your device,I am sorry for you. Maybe you have to stick to the bat-control app and learn how to read it, or RMA your device.

Did the job for me.

So I am ready for summer to join in, got enough juice for the IPS+ screen to stun the sun the whole day lun ;). Rock'n Roll

Edit 121002:

JellyBeans workaround as well.

Edit 120616:

Thank you Asus that the .28 firmware makes my workaround obsolet. Now get rid of this arm5 coding and let the bugger run !!

Edit 2:

Title changed from 'Asus you owe me a blowjob' to something less attractive for trolls.

Should be an obvious solution for everyone. But took me a hell of time to use the next best (second) obvious setting for my w-lan and get the battery saving.

Edit:

Please don't abuse my thread to flame, blame or mob your boss, retailer, dog or whomever. Only confirmation or non-confirmations welcome. If you find another or better or additional solution in the future or the past please feel free to post it. I did not have the time yet to check for the actual amount of powersafe but regarding my normal readings we are gaining the whole lost lot back and don't need to throttle down or ruin our eyes. I reckon the bat is gonna be better because now some of the ASUS optimisation hits some ground.

If you want me to fled off, I have stolen your ideas or you are an ASUS employee with no job-offer, don't PM me.

Thanks
