Is it possible to get the battery status of Bluetooth headphones connected to Linux? Android shows it so I was wondering if it was possible.
I know there are many questions on this argument, but I want to be sure that the answer for old ubuntu version can be used for this version, so this is the question, how can I improve my battery life on ubuntu 18.04? I installed ubuntu in dual boot with win10 and I've noticed that ubuntu run more frequently the fans and the estimated battery life is less then win10. I've already switched to integrated intel graphics card and I've installed tlp, what can I still do?
Battery drains in about 10 hours when the computer is asleep with Ubuntu 18.04, it is a lenovo y520 (7700hq, 1060 with bumblebee).
When I tested no USB devices were plugged in, actually nothing was plugged in.
The sleep mode is s2 - deep. I am not interested in hibernation (it is quite slow and takes a lot of space).
In windows and Mac OS (hackintosh) sleep mode uses 1 or 2% of battery in a day.
As you see Ubuntu shows that my battery is in a charged state at 97%. My laptop is almost 3 years old (battery as well). How should I understand these 97% and are they correct? Under Windows, there is a MSI tool for calibrating my MSI battery, but under Linux I do not know what to do. Appreciate any help in terms of that matter. Thank you.
