Samsung please do something!
1) Whenever I restarted the phone, there'll be an automatic drop of at least 2% of batt.
2) today, I used Waze for 30 mins, the battery dropped 30-35%!
3) I had trouble backing up my WhatsApp with Google Drive, and I accidentally deleted my WhatsApp's Google Drive Backup.
When I reinstalled WhatsApp, all my chat history were gone. When it finally able to back up (with nothing in the app), it took Four HOURS to completely back up to my Google Drive!
