The phone i bought was in excellent condition so i had high expectations when it came to battery health as i had seen eco-friendly/good reviews with high battery health with some even at 100 % . Upon 1st inspection the phone looked brand new except a tiny scratch at one of the corners but overall looks brand new . The battery health was at 80% then went to 79% the same day . I was so disappointed i wanted to return it , they offered to take back the phone as the warranty is in effect . However realising that I am in SA , the process was gonna take at-least 2 weeks minimum and they were probably gonna give me another phone with maybe a battery health in the 80’s , so i decided to keep the phone and replace the battery . Overall excellent device and very responsive customer service.
