Battery drain and button lock?

I just read another thread and got an idea about people's battery drain issues (maybe...).

There is a setting in the "buttons" applet under Settings called "Lock" that allows you to lock the hardware buttons so that when the phone is suspended, pressing the hardware buttons do not wake up the phone (only the power button or an incoming phone call wakes up the phone). Please note this is different from the today screen device lock, the "Lock" settings applet itself, or Jonathan King's onlock program. In the 2nd Verizon ROM (the updated one from UTStarcom), the hardware button lock was enabled by default - that was a change from the first Verizon ROM. So after Verizon users hard reset on the stock ROM, they don't have to worry about making that change to prevent the phone from turning on every time they press a button by mistake in their pocket.

Turns out that in Colonel's custom ROM, the default is unlocked - that is, the hardware buttons CAN turn on the phone when it is suspended.

I just noticed this, and I'm wondering if this is why my battery dropped 70% in 3 hours yesterday when the phone was in my pocket. I've reset the hardware button lock and I will try again tomorrow and see if there is any difference.

Colonel, you might want to consider making that change in the ROM - it makes a lot more sense to have the button lock default to ON, I think. I don't know where the setting is in the registry, but if people want to try it in the interim, you go to Settings...Buttons...then choose the "Lock" tab at the very bottom, and tell it to "Lock all buttons except Power button".


Hopefully that helps someone...
