As all Serene owners know, the battery indicator on the screen has 3 parts before it runs out. I do not use this phone very much so I could test the stand by time. The first part lasts about 3 days but after that it goes pretty fast. With the second part it takes about ± 1 day and also for the third part it takes about 1 day before I must charge again.
My question is, is this normal for the battery to do it like this or is it my battery which is not 100%?
