Hi guys, so I've been noticing an odd behavior regarding my lumia 1520's battery while charging. I normally use my phone until it's 40% - 35% and then charge it. But lately when I was charging it the moment it reaches 53% in a few minutes it will instantly jump to 100% and when I unplugged it from the charger it will somehow fall down to 93% in matters of seconds. Is this normal? should I be worried about my 1520's battery? Any answers or solutions would be very much appreciated. Thank you!
