Hello
So my macbook's battery started to drain like 30~70% overnight when it was sleeping.
My bluetooth is off, so is power nap.
Programs like 'caffeine' are also off.
I really don't understand why it taking so much battery.
😢 PLEASE HELP ME

Hi there joonkang98,
You may find the troubleshooting steps in the article below helpful.

There are several common causes battery drain that you can minimize.
- Take steps to optimize your battery life per the Optimizing Battery Life section earlier in this article.
- A common cause of decreased battery life is a "runaway process." Make sure to check Activity Monitorfor any runaway processes, especially after installing software updates or a new operating system. Installing updates is important to ensure optimal performance for all applications.
- If you are still having battery runtime issues after optimizing your computer's performance and checking for runaway processes, test in Safe Mode. Safe Mode limits the active items on the system and allows testing in a more minimal environment. If the battery life is better in Safe Mode, you may need to do further software isolation for the items disabled by Safe Mode to determine what the power draw is while not operating in Safe Mode.
