Experiencing serious battery draining on Apple iPhone 5c

That could mean a faulty battery, that's why your phone can't hold a charge

Best bet here would be to go to your Apple Store for battery replacement : iPhone Battery & Power - Official Apple Support

The cost of replacing an iPhone 5c battery is 79$

Hope this helps.

Good Luck.

Hi
