It just took 39 minutes to charge 28 percent on quick charging block with all apps closed, but with wifi, bluetooth and gps on. This is exactly how long GSam said it would take. This seems slow to me. In fact, the rate seems to slow as it gets in the 90 percent range. I am used to my Note 7, which charged very quickly. This battery also drains twice as quickly as my Note 7.
Considering that I bought this from a third party seller and it was refurbished, I will probably just keep it and not exchange it with the seller. This is basically a transitional phone. I don't think I will get any better from another refurbished. Everything else on the phone seems to work great.
