Yes, I changed the Samsung battery a couple of months ago. Generally speaking, I am satisfied with the work of the craftsmen. The performance of my battery was inferior, so it needed to be replaced. I would have bought myself a new phone, but I was so used to this model, and there was not much money for a new one. I don't know much about phones, so I can't say anything about the quality of the work done. All I know is that my battery is new and holds a long charge. I ordered a battery replacement service from https://batterywill.com/best-samsung-galaxy-note-4-battery-replacement/. According to my friends' reviews and recommendations, this company is one of the leading in its field.
