I have had my HP 5455 for several months now, and overall I really like it. Nonetheless, there is one aspect that is driving me nuts. If I charge the battery all day at work and then take my Ipaq home and leave it off over night (not charging), when I get up in the morning about half of the battery life is burned off. why? what is even more frustrating is that if I don't have a full charge when I get home, and if I don't charge it overnight, then it fully drains and hard resets. I have sent the unit back to HP twice, once I received a new internal battery coin, and the second time I received a new removable battery. This has still not solved the problem. Am I crazy to think this is a problem? Any suggestions? Anyone else have this ame issue?
Maybe it is one of those features that is killing you. I assume you have already checked to ensure it is not the midnight turn-on and houskeeping that is causing the battery problem? I don't know about the 5455 specifically, but I know that turning on with a Wifi card in the machine can establish an AS connection that won't allow the connection to drop and the device turn off in some devices, depending on settings. I suppose BT could do the same.
Can the radios be set to OFF, so that they won't be transmitting and potentially establishing a connection if the device should turn on, due to a schedule, alarm, or even an accidental button push (you do sleep with your PPC don't you )

iPAQs have always had a problem with this, right back to the original 3650. They simply bleed power in standby mode at a horrendous rate, and I have no clue why - I think it's poor engineering on HTC's part.
By comparison, the Dell Axim was down to 54% after 10 days of standby - and it wasn't even fully charged to begin with!

Yes, but it shouldn't be 50% per day. On my 3650 it was about 10% per day. I easily lasted a weekend without a single recharge.
taxlax, it's more likely what Sven mentioned is happening: that your iPaq is staying on when it turns on at midnight to rotate appointments and stuff. You should check at that time. Some applications force the unit to stay on if they're left running.
