My phone has been suddenly losing its battery charge quickly after the latest update. This happened early this year and samsung was able to fix it with a new update. I hope this will be soon fixed or will plan to move to another phone company very soon as this has been happening frequently with updates.
same issue here. this happened in June of this year as well, then gradually seemed to fix itself. now it is draining in about 4 hours.
I tried the procedure to empty the cache partitions, and this seems to be of no help either.
I allowed the battery to run down, then recharged from 0%. Still no change.
I do also share the same issue on my S10e.
Seems like Samsung have made it on purpose so we have to buy new phones.
