I purchased a refurbished Samsung Galaxy S7 in December 2018 and a few months ago, the battery started to drain fast. Texting would cause it to lose many percentage points. I contacted Verizon Customer Support and they replaced the phone under warranty. Unfortunately, the replacement phone does the same thing and there is nothing more Verizon can do.
Is this just an issue with the S7? Or are all refurbished phones like this? Just disappointed.
