Macbook Pro 2012 shutsdown suddenly at 25% battery I have a Macbook Pro Unibody Mid 2012 and used the battery for only 118 cycles.

Since a few weeks ago whenever I'm on battery and it reaches &lt;25% my Macbook shuts down immediately (no warning, no saving, so all my work is gone if I let it happen)

I'm okay with battery losing 25% of its capacity! but shouldn't this be from the top? I mean it can just reach to 0 faster, or display warnings!

Battery is really working, it still holds for ~3 hours, and I just can't replace it yet (and also no warranty, no apple shop near me)


  Is there an application out there which can change my battery sensor functions and set 25% = 0% (I mean it works just like a normal Macbook with less capacity available on battery)?


P.S. Already tried installing Yosemite, and resetting SMC

Every battery in a MacBook has a battery processor, which, from time to time, should be recalibrated. Like this:
1. Fully charge your Mac
2. Use it until it dies
3. Once dead, wait at least 5 hours, no less, then plug it in and charge it to 100%, without using it.

The battery percentage reading on your Mac should now be more accurate.

If this doesn't fix it, don't but a new MacBook or give away this one, your MacBook just needs a new battery.
