Haptic Feedback

[badbradd2]

I'm curious if anyone knows whether or not Haptic Feedback uses a ton of battery or not really much at all. I want to get the most battery time out of my phone, but love the haptic feedback. If haptic feedback really doesn't use much battery power then I will just keep it on, otherwise it's a simple sacrifice for longer battery.

Haptic Feedback shouldn't be an issue what so ever.

I would imagine that compared to the power the screen sucks down while on, the haptics are a very minor drain .

I wouldn't worry about it; unless you're one of those people who wants to squeeze out every. last. milliamp-hour.

Every time you touch the screen the screen the vibration motor kicks in.
It HAS to be a larger drain then not using it at all.

Every one uses their phone different though. Download an app like juiceplotter and try it for awhile with and without while monitoring the battery usage.

Yea, I'm not saying it doesn't use any battery, just that in the grand scheme of things it probably isn't a huge factor in battery usage, especially compared to the cellular/3G/wifi/4G radios and the screen. Kinda like ordering a diet coke with your super-sized bigmac meal

That said, I've been wrong before, and would love to see any numbers people come up with.

I would imagine using the battery to create enough physical force to shake the phone would require some amount of power...I've always been curious about this myself. Sounds like a power drain to me.

Yeah, I've heard arguments (before haptic feedback took off) about the energy needed to induce these vibrations' and the potential negative effect on battery life. Didn't seem like an unreasonable school of thought, so I went ahead and turned it off for the on-screen keyboard and left it on for the 'physical' buttons. Haven't noticed much of a difference in battery life from my gf's evo though.

Like I said, it shouldn't be an issue.

If it uses any battery at all, it's nothing to make a noticeable difference.

I'd just drop the topic
