iPhone starting with 80% battery

[robbie12345]

As the title says i woke up this morning with my phone still plugged in. I then proceeded to play clash of clans for about five minutes and check my Facebook. After all of this i check my iPhone 5 and its at 80% battery life.

I tried restarting my phone but to no avail. It had charged for a good 11 hours and was still at 80%

Two more things: i had lte on overnight whereas i normally have wifi

I've been charging it very much recently up to three times a day because i have been using it very heavily

Thanks, robbie

Have you tried recalibrating the battery?

How would one go about recalibrating it

I suppose you could try draining your phone's battery all the way down to 0% where it shuts itself off and then recharge it back to full again.
