    my dhd battery is fine for normal use, ive done all the usual things to increase the battery life and im happy with how long it lasts

    but when im travelling i like to watch a film or 2 but the battery only lasts 40 mins:mad::mad::mad:

    any tips on how to improve on this?

    want to be able to watch a film with a fully charged battery and have atleast a half charge still when the film ends

    You should probably be getting over 40mins of video out of your phone. I can stream a good 2- 2 and a half hours of video before my DHD battery dies.

    Do you turn everything off when watching the video? What app do you use to watch films? What format are your films in?

    Bear in mind that different types of video will be more demanding on the DHD's processor.

    everything is turned off all the time, i just use the video app that came pre installed on the phone

    films are in avi, i uninstalled advanced task killer last night and managed to watch a 120min film and still had 25% battery left

    so it looks like that was draining quite a bit of my battery

    Well it is a phone and watching a film does drain the battery. If you took a laptop away the battery would drain watching a movie, not sure there is any other way round it

    I barely get to 50% of the battery when watching a movie. My battery consumption is pretty good. I have Green Power running on my DHD which is free from the market. Try that to see if it makes any difference.

    Have you checked what is reported to be draining the battery? Go to Settings -> About phone -> Battery -> Battery use. I imagine you'll find that the display is responsible for the vast majority of battery usage... mine regularly shows a figure around 80% which, perhaps paradoxically, is a good thing as it means that other processes aren't using up much power. It's worth tapping the graph shown there as it gives further useful insight into what's going on.

    Assuming that the display is what's draining your battery, have you tried reducing the brightness setting?

    but it shouldnt drain it so much that u cant do much else with it, the phone is designed as a video phone and was one of the main selling points

    my laptop is too bulky to take away but it does have a 8 hour battery and films are fine to watch on it

    will check out green power and see how it goes

    the screen is using about 60% i can reduce the brightness but i do like my screen set to max

    as i said before, ditching advanced task killer has made a quite a bit of difference so hopefully if i can save another 20% ill be happy with 45-50% battery after watching a film

    I'd suggest you try the auto brightness setting instead. This is what I do and, generally, it works well. The only time I override it is at night when I've got an app which sets profiles so, at night, I select a profile which reduces the sound volumes (except alarms) and sets the display brightness to 0%, as even the minimum that auto brightness goes down to is still too bright (the 0% is maybe a misnomer as the backlight is still on, albeit very dimly).

    The fact that, even at maximum brightness, the display is still only accounting for 60% of the power drain does imply that something else is eating the battery - does the battery use screen not tell you what this is?
