Is my battery going bonkers, or just a calibration issue?
To preface, just so we’re clear, water fell on my keyboard some months ago (maybe January). I dried it up, let it for more than 24 hours upside down etc. I added this because it might be a cause, but I’m no expert in this regard.
Anyways, today my battery was at 20%, so after I fired up IntelliJ IDEA, indexing started, all fans started screaming as is tradition, and then, this: battery fell to 1%.
I plugged it in, and in a minute or so, it went back up to 20%. What’s weird is that coconutBattery showed different capacity readings. First row is when it was charging, then second is after unplugged (IntelliJ was indexing, so it was hard at work), and then after replugging you can see the capacity starts increasing again.
The issue seems to be more prominent when IntelliJ is hard at work. Now that I’m writing this, after indexing stopped, the situation seems normal.
It also happened twice before (after the water spilling), where the battery was like 30%, and after opening IntelliJ IDEA the MacBook shut down immediately. I did a “pre-SMC” reset (the steps Apple recommends for laptops with T2 chip, before trying an actual SMC reset), and I guess I didn’t have that issue anymore.
Right now I’m going to try an SMC reset, but I’d appreciate your thoughts here. Do you think it is the battery, SMC, something else?
Это хороший вопрос?
