 4 There are at least 2 command you can use,
 5  each will tell the percentage of battery.
 6 
 7     acpi
 8     upower
 9 
10 I made a video to demo it, if needed,
11  you can view the youtube video:
12 [how to get battery status](https://youtu.be/1De5MzqBz7I)
13 
14 By the way, I am using Ubuntu 16.04.
15 
16 ## acpi
17 
18     acpi
19 
20 This is what I got:
21 
22     Battery 0: Charging, 86%, 00:12:32 until charged
23 
24 
25 If you have no acpi installed, use the following to install
26 
27     sudo apt-get install acpi
28 
29 ## upower
30 
31     upower -e
32 
33 or
34 
35     upower --enumerate
36 
37 
38 As example, this is output on my laptop:
39 
40     /org/freedesktop/UPower/devices/line_power_AC
41     /org/freedesktop/UPower/devices/battery_BAT1
42     /org/freedesktop/UPower/devices/DisplayDevice
43 
44 
45 
46 ### Then use one of the above output in the following command
47 
48 
49     upower  -i  /org/freedesktop/UPower/devices/battery_BAT1
50 
51 
52 This is my output this time:
