Who have replaced the battery on their Passport?

I have had my passport for about a year and a half and have started to notice a decrease in the battery life. when it was new I could go a day and a half of frequent use, now it will go to battery saving mode after about 8 or 9 hours. Just wondering if other passport owners have had to replae their battery?

Waiting on a new battery to arrive from Aliexpress. It should be pretty simple as I've already had the thing fully apart to replace the keyboard.
