    My non-branded GSM hero eats battery.

    So I decided to check some things out. These numbers are starting from 100% battery, and after a reboot - the only thing I open is settings to check the battery level, and then I lock it and leave it for 6 hours. In all cases the final awake time is low, less than 15% (because I'm doing nothing with it).

    Full data-sync mode - gmail sync, twitter, etc - about 10% battery use per hour.

    Retro mode - GSM only, data switched off - 6 % per hour.

    Airplane mode - 3.5% per hour - WTF?? (Awake time ~1%)


    Why is battery consumed when it's doing sod all?

    IMO, because it's not doing sod all. And this is the one real bugbear I have with this phone. Something, somewhere is kicking in and killing the battery.

    I've already posted loads about this and it's got to the point that I'm sending it back to HTC. I really haven't the patience anymore. Mine can work almost perfectly for a week, then suddenly (with no changes to settings or apps) start draining battery at 10%+/hour even when I'm hardly using it. Frankly, this is unnacceptable. And I'm bored of it. No matter what I do using App Managers, Task Killers, NetMeter, TaskPanel, etc, it makes sod all difference. :mad:

    The fact that HTC, Vodafone and the Android crowd fail to accept this is a common problem is beyond me. Which pretty much means no-ones taking full responsibility.

    Oh well ... we'll see what happens ...

    Hope you get yours sorted.

    What kind of Hero (T-mobile, Orange, Unbranded) are you running and what firmware and radio version are you on?

    Mine is white unbranded and on the latest official HTC ROM xxx.05 . I've also tested on Modaco 2.9 with the JU radio ROM. (although I see the same behaviour on EU and IU ROMs too)

    My girlfriend's T-mobile black, on the latest official T-mobile branded ROM can end a heavy day at 40% - long calls, permanent data connection, the lot. Mine is dead at 4pm.

    <In fact someone offered me

    So..... I got another Hero.

    Completely different battery drain profile.

    21 hours with everything on, a couple of calls and texts and browsing - 23% battery drain. Happy as larry with that.

    My theory is some Heros have problems!
