Phd life takes several batteries’ life

Entering the fourth year of my grad school, apparently now I have to buy a new one, again, after replacing the first one a year ago.

Here’s the screenshot from today:

The battery was dead yesterday, and unexpectedly be able to be charged again this morning at home, and suddenly went dead again later when I was working at the office. So much of battery’s adventure, I either need to buy a new mac or finish the school immediately, I’ve been too long being a phd student (nah. I like to be one so I will extend the time as far as possible. Let’s just get a new battery 😛 )
