Pending which phone you have and how many apps you have. I really only do it when I notice my phone slowing up, which is about every 4 days or so. Its not pointless it adds memory that is trickled away during use.

I'm with several others I only do it if I'm having issues on the BB. However on earlier builds of the storm os I did pulls daily, bit after os 4.7.0.151 that was no longer necessary.

I also use QuickPull and have it set for once a week (Sunday night). The only other time I do a battery pull (using QuickPull) is if I install an app that requires it; soft reset usually takes care of any OS glitches (hasn't happened on my Tour, used to happen on my 8830).
i only do it when my phone is being slow. i had quickpull and it would always turn my phone off, but it wouldnt come back on unless i hit the power button.

Only when something seems odd with my BlackBerry, which for me has been like - what, maybe 5 times this past year?
I usually clear my cache and memory resources as I go along, so my cheepo 8330 hasn't seemed laggy, been pretty happy with it.
Do need to upgrade sometime soon though.
