Hi
I have a W4 since few months, and I really enjoy it.
The main issue is the battery: I see review praising the 10 hours of use; but I am really not impressed of the battery life.
I use it mainly in the evening in bed, to watch youtube videos or read articles. Occasionally I play casual games, for 10-20 minutes not even every night. Overall my usage is not that intensive.
The battery sometimes just go down like nothing, when the tablet is mostly in sleep mode on my desk. I need to recharge it probably every 2-3 days. Considering that the battery should last 10 hours; I would expect to recharge the device probably once a week, like I used to do with an old iPad 2.
I am not sure if I have a defective unit, or if there is something wrong on how I use the device. I have also a 10 inch Asus with Android 4.4, with similar usage (my wife use it), and I recharge that one less often than my Iconia. Which is strange since the screen is bigger and the OS is not as optimized as Windows 8 ( I assume).
What could I do to find out what is causing this ? I quit apps every time that I finish to use them; the only one that usually stay open is youtube, since I pause videos and continue them the day after, so I can start from where I left off; but the device is in sleep state all day, so should not use power at all.
