I would like to know the ratio of these reviewer's Samsung phone collection that the battery became damaged by just sitting for long periods of time.
Samsung could have a problem with quality control, or their overall battery implementation. How big of a problem is the question. But this doesn't look good when its multiple big names in the review field, claiming Samsung is the culprit the majority of the time.
Another issue I have is, why is this noticed now? Some of those phones are past 5 years old.
I still have these Samsung phones below in my draw, and probably mess with them once or twice a year. Never had any issue with bulging or exploring batteries. My collection is miniscule though, so it doesn't mean anything.
S3 .... Original battery, but only lasts about 30mins screen time. Back when Samsung threw every feature they can think of at us.
Note 4.... Original battery, lasts about 2 hours screen time. This phone was used HEAVILY!!!!! I took it back from my mother when it finally became obsolete. 😅
S7 Edge .... Battery life is still good, but it wasn't the best to begin with. I kept this phone cause it look so good with the gold color. GOLD IS BEST!!!
S8+ .... Battery life is still good enough to be used as main phone. And this came out when Android finally got stand-by battery life on point.
