Thank you for your comment. Battery backup of this earpod is really good. With case it provides upto 45 to 50 hours of battery backup and out of the case it provides 6 to 7 hours of backup.
Only one problem with this earpod is when you connect it with bluetooth, it volume becomes high (100%) everytime. So, you have to be very careful before inserting it in your ear. First you have to down the volume every time when you connect it to bluetooth.
