Should I let my iPhone trickle charge at 100%?

Some websites and apps are saying you should let your battery trickle charge at 100%, which means the percentage might say 100% but the unplug symbol isn't there yet, should I wait for that symbol to be there even though it's at 100%?

Doesn't matter
smartphones stop charging automatically when they are full.

Iphones don't have that issue, doesn't matter either way.

  • Why won't my iphone 8 plus charge to 100 percent and stays at 98 percent? I don't leave it all night charging. I always wake up around 7 then charge it for like 2 or 3 hours and it will stay at 98 percent, but when I restart it, it would go to 100. And I just recently bought it. Why is this problem?
  • Why won't my iPhone 5s charge to 100%? My new iPhone 5s will not charge all the way to 100% even after leaving it on the charger all night. Is there any explanation for why this is? And is this something I should worry about? Is this evidence that my battery might die early? (Please excuse the infinite screenshot picture., I was having a bit of fun. I just took a screenshot to show you the battery life.)
  • What will happen if I didn't charge my new iPhone 5 to 100%? Will it affect my phones battery life? Some people say you should charge it 'til it reaches 100.
  • What will 100 mbs let me do? I recently got an iPhone with a plan that allows 100mb per month. And I don't want to break that amount. Does anyone knows how many websites or fb pages I can surf with 100mb?
