Hey everyone, I've been having problems with my battery for like a year and a half, capacity suddenly dropped immensely, I'm now down to 23.3% of design capacity, despite only 345 load cycles. When not charging, the battery depletes very quickly, and often shuts down without notice, around the 30-70% battery remaining. I've tried resetting the SMC from time to time, and nothing improves the situation. Should I just bite the bullet and replace the battery? The strangest thing is that one of my friends who bought a MBA around the same time has exactly the same problems.
