Why does my batter drain so fast and charge so slow?

[AC Question]

why does my batter drain so fast and charge so slow?

i got my galaxy s6 edge before yesterday and i charged it at the at&t until it reached 100%. Then i went home and used it a little at night. When i woke up it was around 30% and i went to school with a portable charger and charged my phone when it reached 15%. when the portable charger died my phone was at 45%. after the school ended it was at 5% then i went to go charged it with the charger it came with. when i plugged it in it said approximately 6 hours until full battery. so i waited 6 hours and used it a bit over night. when i woke up it was at 75% and the battery is dieing very quickly. What do I do, did I damage the battery with the portable charger?

Welcome to AC.

The battery may be faulty. The warranty would cover it if so.
Also, keep an eye on your battery usage stats....it sounds as if you may also have a drain there.
