I have installed Ubuntu 16.04 on my Apple MacBook Air (2015). The two major problems I face issue with Battery Backup.
The battery backup has been significantly reduced to 2-3 hours. The OsX was comfortably giving me 7-8 hours backup. Another strange thing I noticed is that, even if put my laptop on sleep mode (with full charge), the battery becomes empty after a couple of hours. It seems some applications wakes up frequently and consume the power. Do we have any application which will show the battery consumption for a long time, for example for lat 24 hours (or during a full discharge cycle)? I found powertop, but it gives only the statistics when the system is on (not sleep).
