Galaxy S3 Mini - Battery graph

[Paula Silveira Rodrigues]

Hello,

I am having problems with my S3! Battery is draining too fast! In battery graph, the Android OS is almost 60%!! Is this what is causing the battery's drain? What is this? How can I solve this issue?
I would appreciate your help! Thanks in advance!

if you have added a lot of files on the phone the system may take some time to index them and create the thumbnails of the pictures. you can reboot the phone and see if this start again
