My husband and I have the same phones. We also use the same charger. My phone charges and holds the charge for days. His holds a full charge for less than 24 hours without him using it at all! Any help would be appreciated.
Defective battery capacity or battery controller in phone. Perhaps after a factory reset a warranty replacement is called for.
I did a factory reset as you suggested. SUCCESS! All is well now.
Thanks for your help,
