loss ~4% of my battery charge in each 12h.

the most obvious cause could be Wake-on-Lan, that leaves a part of the
system active (specifically, the network card). With the "ethtool"
program you can queary and set the state of this.

My network card have option WOL "disabled"

# ethtool eth0 | grep Wake
Supports Wake-on: pg
Wake-on: d

Similarly, but less likely, there is wake-on-serial and wake-on-usb, in
theory those are possible too but I've yet to see one of those on any
of my machines.

My laptop don't have serial port and wake-on-usb is disabled too:

# cat /proc/acpi/wakeup
Device S-state Status Sysfs node
LID0 S4 *enabled
RP01 S4 disabled pci:0000:00:1c.0
RP02 S4 disabled pci:0000:00:1c.1
RP03 S4 disabled
RP04 S4 disabled
USB1 S0 disabled pci:0000:00:1d.0
USB2 S0 disabled pci:0000:00:1d.1
USB3 S0 disabled pci:0000:00:1d.2
USB4 S0 disabled pci:0000:00:1d.3
USB7 S0 disabled pci:0000:00:1d.7
MODM S4 disabled pci:0000:00:1e.3
PS2K S4 disabled pnp:00:07
