Is it bad to let an iPhone 5 battery die out?

I was just wondering, because my friends say you have to let it drain down to 0 and then re-charge it as soon as you get the phone. And I got the phone yesterday. Is this true, and should I let it die out and then charge it?

No, it's a normal lithium battery. You don't have to wait till it dies to charge it.

It is always best to drain a new phone and then give it a 16 hour charge to increase potential battery life. You can also do this every now and again so the phone receives a full charge

  • Why does my iPhone battery die so quickly? I had my iPhone for about a year and a half, and recently I've noticed that the battery is draining incredibly fast. I've always had it on 3g internet/Wi-Fi and the battery never died this fast so I don't know what the exact problem is. I charged it to 100% yesterday and I only used it for maybe about 10 minutes and left it untouched for the rest of the night. Today when I woke up the phone was dead. I haven't changed the settings or anything fyi.
  • Why does my iPhone battery die so fast? I have boost magic, which is supposed to help my battery last longer, and I kill all my apps when I'm done using them. I go from 100 at 8am and I'm at 60 by 9:30am. And I hardly use it too, just to look up information quickly and I just set my phone aside. I let it go down to 20% battery and let it charge over night. It just started doing this recently. I also keep my brightness to pretty much 0 with the auto brightness on. And it still dies fast. What can I do?
  • Why does my iPhone 4S die when my battery is full? I recently got a used iPhone 4S and the battery is terrible. My battery can be at 100% and ill take a picture and it'll die. I can't use my phone for more than 30 minutes at a time. I've even had to buy a portable charger and it will still die. It's dies randomly all of the time even if my battery is full. What should I do? What's the problem?
  • Why does my iPhone 4s' battery die so quickly? I'll have it fully charged when I wake up at 8, then it's basically almost dead around 1 in the afternoon. It use to not die this quickly. But now it's like crazy how fast it dies! I'm on Twitter a lot and I text a lot. But I use to always do that too, and it never died as quickly as it does now. Any tips to help save battery?
