After the blunder that was Galaxy Note 7, Samsung moved forward to make sure that Galaxy S7 and S7 Edge users are thoroughly satisfied. While the Android 7.0 Nougat update is finally here for the flagship devices with exciting new features, not everything is picture perfect.While Android 7.0 Nougat does promise an improved battery life, latest reports suggest that the battery life of the Galaxy S7 and S7 Edge has suffered under the new update. A series of tests have revealed that both of the devices have received a blow in battery life of around 10%.

How was the battery life test conducted?

The screen brightness of the Galaxy S7 and S7 Edge were both turned all the way up to 200 units, and the same testing standards were used as for most devices. However, it was also noted that the battery life of the devices also declined with the age of the device.After taking the battery test on Android 6.0 Marshmallow, the devices were updated to Android 7.0 Nougat running kernel version 3.18.14. After installing the latest updates, the same battery tests were conducted once again and the following scores were recorded:The Galaxy S7 scored approximately 6 hours of battery life on Android 7.0 Nougat, while it was 6 hours 37 minutes on Marshmallow. Whereas the Galaxy S7 Edge ran for 6 hours 35 minutes on Nougat but scored 7 hours 10 minutes on Android 6.0 Marshmallow.This means that the Galaxy S7 has suffered a 9.4% decline in battery life, while the Galaxy S7 Edge battery life has dropped by 8.1%. Hopefully, Samsung can address the issue of declined battery life and work on an update to bring back the lost battery life, if not improve it even further.
