Standard rechargeable batteries do not work well with phones, so I do not know, probably a different charge or different consumption.
They load quickly, do not wear out too quickly.
Now I have seen other batteries last longer but as I already said few are specific batteries for phone so it is already very good, prefer these batteries for standard rechargeable batteries that are not specific to phones.
So why 4 stars / 5? Because there are not many products of this type is not much competition.
