To get some info about your battery life, open your terminal and enter:
$ cat /proc/acpi/battery/BAT1/info
this will return you some useful info!
take a look at this output:
- present: yes
- design capacity: 4400 mAh
- last full capacity: 4300 mAh
- battery technology: rechargeable
- design voltage: 11100 mV
- design capacity warning: 0 mAh
- design capacity low: 129 mAh
- cycle count: 0
- capacity granularity 1: 1 mAh
- capacity granularity 2: 1 mAh
Well well, at lines 2 and 3 we can notice that there is a gap between the values. If you charged completely your battery and it always doesn’t fit the same value, it may mean that your battery has lost some of its capacity! =/
