I think the idea of location based reminders is cool, but I am afraid to set one for fear of draining my battery. If I set a location based reminder, will my iPhone 4S be constantly checking my location to see if I have arrived? I would like to set reminders for when I'm on vacation this summer, but not if my phone will be checking all day to see if I'm in New Jersey yet.

Note: I just switched from a Palm Pre, so I am probably more battery conscious than most users, since the Pre barely lasted 8 hours on standby. If you ever used it for anything, you had better have spare batteries in you pocket!

It does not drain as much battery as you would think. Try it out a few times before your vacation.

I use location based reminders all the time and I have not experienced any significant battery drainage out of the norm. You should give it a shot.

I will try, but I am still curious, how does it do this without significant battery drain? If I left TeleNav running for a couple of hours, it will end my battery. How can it know where I am in order to remind me of something without constantly pinging my location?

I haven't noticed a drain. Twice a week when I get home from work, I get a little reminder to take out the garbage. Since the 4s launch. (before then I'd remember to take out the garbage the next morning when I heard the truck coming up the street.)

I tried it for a couple of days and found it to have a very noticable affect on my battery life. It didn't kill my phone but probably took it down an extra 20% for the day.

How do you set those up?

Via Siri is how I go about it. "Remind me when I get home to ..."

This is what I do too, well now I do. If you sync reminders with an Exchange server you need to turn that off first.

Why do you have to turn that off if you sync reminders with an Exchange server?
