Battery Health Clarification Question
I keep reading that I should "completely" drain my battery once a month to make it have a longer lifespan. Assuming that isn't total BS, just what is "completely" drained? It won't let you go to zero, so is 5% good enough? 10%?

I just got my iPhone a few weeks ago and had the same question. Apple's advice contradicts what battery manufacturers and vendors recommendation for frequent charging. Manufacturers say deep discharges shorten the life of li-on batteries. Additionally li-on batteries have no memory so they don't need a deep discharge unlike some lead acid batteries designed for deep discharge. I have always charged my phones and other devices frequently and have had no problems. Does anyone have a differing experience?

Well, if you want your battery to last as long as possible, and by that I mean lifespan, you're supposed to keep it below full charge as well as avoid deep discharges. Basically, you want to keep it around 40-70%. Also, you want to keep it cool as possible and finally, you want to charge it as slow as possible. I think my phone charges faster on my iPad wall charger than my iPhone wall charger, you're supposed to avoid that.

I've been using a app called Battery Doctor. it recommends letting the batt drain to below 20% percent but not completely drained then charge. Do this once a month. I've been doing this since June seems like it's cool. I've had all of the iPhones and never had a battery crap out yet.
I still have the first gen iPhone that I use as a iPod. It takes 4-5 days for the batt to die on standby and it's 5 years old.

There are at least three apps called Battery Doctor which pop up in my App store. Which one do you refer to?
I have an iPhone and I just bought my second iPod Touch - would be nice to conserve the battery on the Touch as long as possible - I'll change the iPhone with the next-gen anyways.
