    Hi guys i just bought myself a transformer and am not getting good mileage from the battery
    The first charge at 8 hours definitely did not last more than 6hours. This is a far cry from my wife's ipad 2 out of thebox

    Is this normal or did i get a faulty set?

    Welcome to the forum.

    It depends on what you were doing for those 6 hours. If it was 6 hours of constant use, streaming movies with the screen brightness set to max, that might be about right (can't say for sure, I've never done that). I regularly go 2 to 3 days with my usage, but that's just a few hours of light use each day.

    Can you give us more of an idea of what was going on in those 6 hours?
    What widgets were running?
    Do you have a dock?

    Thanksfor replying!
    I was streaming videos 30% of the time. The rest was just surfing. Screen brightness was set to auto. Also had torrent running in the background
    No dock!

    According to the specs on the Asus website, we should get 9.5 hours playing a 720p video. Note that says 'playing' not 'streaming', which to ME implies that the video is on the SD card of the TF.
    With all that you were doing, sometimes more than one 'streaming' thing at a time, it seems reasonable. Maybe just a bit short, but *I* wouldn't call it bad.

    For mine it sad that it might not reach its batteries full potential until after several complete draining and full charging periods and i have found that to be true

    Apple has mastered power management, I've never seen a device with as good a battery life as the iPad line, it's one of the few things I really miss since switching to an android tablet with near-identical specs.

    Torrents will eat batteries alive. I wouldnt even suggest running them on a full-fledged laptop on battery power due to the drastic increase of consumption (if your surfing the web, the NIC is only active (usually in half-duplex download mode) for the most part while loading the page, afterwards it goes into idle mode, if a torrent is running then the NIC is active 24/7 both uploading and downloading. (full duplex mode))

    On the other paw, I tend to get around 5-6 hours also when online (only syncing and checking various emails) and watching local 720p media from the SD card, so it may simply be the wifi itself drains a lot of power. If I can remember, next time I'm spending a long time watching video I'll turn off WiFi and let you know how/if it changed power consumption.

    I stream videos from Media PCs. I play games. I surf and stuff. I would say I test the old fashion way....Use the damn thing. I am very pleased with the battery life. I generally get two days or so. The battery specs are very true...it does last a long time.

    Now in the beginning...........Christmas

    I FULLY charged the battery BEFORE even turning it on....about 8 - 10 hours. Then used it and let it drain down down to nothing....0%. Then recharged again...about 8 hours. Used again until 0%, then a complete recharge again. The batter life is outstanding.

    With a fully charged battery it will go 9 hrs while watching 720p videos constantly. But there are factors in that. Is WiFi on, bluetoot, screen brightness etc etc.

    My brightness is set to about 40%. BT & GPS set to off when not in use.

    I watched 2 movies back to back which I assume is approx 4-5 hours and still had approx 50% battery power remaining. But I was also using external speakers.

    Just be careful with your settings and it should last plenty long.
