I bought this phone about a year ago that time I thought its a good choice to buy it vivo y21L comes with 2500 mah battery 1gb ram 16gb internal memory and 4.5 inch screenLets start with battery backup first it has 2500 mah battery so dont have that good battery backup we need these days it takes upto 2-3 hours to get fully charged but dont give much time in returnIts network is really good . Have an average cameraDue to 1 gb ram many apps take a long time to open and it makes phone really slow it costs 7500 rs in which we can have many other good phones
