Yet another battery drain and Service Battery problem

I want to just make sure the battery problem is just caused by the "aging" battery not software issues. And hopefully I can get some advice in addition to replacing the battery.

MacBook Air 13-inch, Mid 2012

Mavericks 10.9.5

Fresh Re-installed + Security update 2016-004

I had massive battery problems since several months (i.e. battery drain, mac show 0% and does not wake up from hibernation although there is actually 90% battery, unstable Wifi...etc). So I decided to reinstall the OS and also installed the security update.

At first I have Service Battery warning... (not sure since how long)

and the Full Charge Capacity varies a lot while charging and discharging

To experiment how the Macbook consumes power I have done a experiment....

I reseted SMC and NVRAM and then performed battery full discharging and charging calibration once.

Uplug AC, let Macbook run on battery

At 15:58 I close the lid to make Macbook sleep

At this time point ioreg -rc IOPMPowerSource showed

"MaxCapacity" = 3967

"CurrentCapacity" = 2462

At 18:08 I open the lid to wake up the Macbook

Now

"MaxCapacity" = 3950

"CurrentCapacity" = 2185

almost 300 mAh for 2 hours (hibernate, see below) for the battery!

Is it normal?? For a battery with 381 charge cycles

Should I try to calibrate the battery again?

or just keep using before the battery die?

better settings to save battery?

I have actually another Macbbok the same model still running Mountain Lion without any software update. It does not have such battery issue although having similar usage.

The following are all logs and outputs

I configure the Macbook switch to "Hibernate" 10 minutes after sleep starts.
