Poor Battery life on MacBook Pro 2018 13" running macOS Ventura

Batteries are considered Consumable Products. Over time it will degrade to a point where it needs to be replaced.

The usage is normal as the capacity will go up and down all the time and never stay always at 100%. Apple Batteries are rated for 1000 Full Battery Cycles and / or 80% Capacity before needing Evaluation or replacement.

For additional reading on Battery and Apple Computers this link may help. About battery health management in Mac notebooks and especially for the M1 / M2 and Big Sur, Monterey / Ventura If battery charging is paused or on hold on your Mac

Depending on the Age of the computer, some aspects from the above links, may or may not apply to your computer.

A feature introduced into Big Sur & Monterey and Ventura was to preserve the number of Full Battery Cycles - there was an Algorithm coded into the macOS. It is perfectly Normal for Big Sur , Monterey, Ventura to Pause / Suspend charging the battery beyond 80% and hold it at that level. One can nudge / over-ride this by clicking the Battery Icon on Desktop Top Bar and allow charging beyond 80%. From observations, it will Pause / Suspend again once reading 90%. Same procedure to over-ride and will charge to 100%

Hi, I am currently experiencing a very poor battery life after I update my 2018 MacBook Pro 13" to macOS Ventura. Previously on macOS Monterey, it could lasts for about 6-7 hours on my daily use, where I usually opens pdf files, Microsoft Office apps, Safari and Spotify. But now, the battery could only lasts for up to 2 hours.

The device also gets really really hot during the usage. The fan sometimes spin very loudly and the metal body above the keyboard feels very hot.

I wonder if anyone gets the same issue as mine? I am so dissapointed because I have to charge and discharge even more frequently and also I can't work on my lap anymore regarding the heat.

See this references for some insight

My battery runtime is low
