Q: Macbook Pro retina battery problem

Hello. I have an macbook pro retina (early 2013), and after update to mac OS sierra , when it will have around 40-60 minutes worth of battery left, around 30% or 40%, and it will just shut off. No warning at all, it just turns off .

I plug it into the mains and turn it back on and it says I have at least 30% battery left. It's my battery dying or is't just sierra problem ? Thanks!

I

MacBook Pro with Retina display, macOS Sierra (10.12)

Hello andreescu90,

I understand that your Mac is unexpectedly shutting down when there's anywhere from 30 or 40 percent of charge remaining indicated. In such a situation a reset of your Mac's SMC can often help.

Shut down the Mac.

Plug in the MagSafe or USB-C power adapter to a power source and to your Mac.

Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time.

Release all keys, then press the power button again to turn on your Mac

If your MacBook Pro continues to shut down unexpectedly, you can run Apple Diagnostics to get a better idea as to whether the battery may need service. You can access Apple Diagnostics by shutting your Mac down and holding the D key down until Apple Diagnostics begins.
