[AC Question]

My S6 has a 3.7 v 1500 mAh battery...

I have a Samsung Galaxy S6 SM-G920F 32 GB (FACTORY UNLOCKED) 5.1" QHD - International Version.
All specs I have read about this phone indicates the battery is non-removable Li-Ion 2550 mAh.
Why is my phone's battery not the one in the specs I've read? Please help...

Hello. Try running an app such as Genuine Galaxy, Phone Spec, or Antutu.
