We recently received a tweet, depicting a Galaxy S8 owner’s battery usage statistics. You won’t see me downgrading to 720p on my S8 or S8 , but props to him for doing so and testing it out.
According to him and the info displayed on his device, he’s not only getting a solid day of usage (24 hours), but nearly 9 hours of screen on time (So T). Our question to you, Galaxy S8 and Galaxy S8 owners, what’s your battery life been like?
This occurs due to the difference in EFS location in newer and older Samsung firmwares.
Several people who tried downgrading to Android 4.1 or 4.2 from Android 4.3 have reported this issue.
If this tutorial worked for you (and it should work), please leave a comment below and do not forget to mention your phone model and the OS version from and to which you downgraded.

To backup your EFS partition/IMEI, please refer to the following tutorial: How to Backup and Restore IMEI on Samsung Galaxy Devices Installing a firmware version that is lower than the current one is just the same as installing a higher one, but you have to do one more thing that you do not usually do.
I’m going to bed with about 40-45% juice left and 3 hours of So T. Global Android version distribution as of August 2017.Android Marshmallow is the most widely used version of Android, running on 32.2% of all Android devices accessing Google Play, while Android Lollipop runs on 29.8% of devices (76.8% on it or newer).I have not been able to test for downgrading to GB from JB.All the same, I would like to warn you that Those willing to downgrade their Galaxy device to Gingerbread from Ice Cream Sandwich or Jelly Bean should not follow the method given here unless you have the firmware files with Bootloader or PIT.
