I have the 13 inch macbook pro every thing is amazing even battery life I have had it for a week and now it died at 3 percent if this continued in a few months it would die at more than 50 percent what should I do please help and tell if anyone has this issue
 
Doesn't it make sense that it would shut itself down with only 3% of the battery remaining?

There's a few threads about running battery diagnostics, health, etc. - I'm on mobile, but hopefully someone else can chime in.
 
Oh no. You are adding to the conspiracy theory that Apple is overstating their battery life by 17 minutes! I've never run mine down to nothing, so I can't comment. Lowest I've gone is about 5%, sorry. Interested to hear if this is normal and just happens or abnormal.

Edit: BTW, you might want to clean up that title and add "battery at 3%". The way it reads, people are going to be disappointed you're not talking about a massive hardware failure.

Don't worry man. 3% is a really really low amount of charge left. It's making sure it has some juice in reserve.
 
Usually at 3 or 2% any of my MacBooks can shut down, depending on what I'm doing.

Nothing unusual at all. Sorry to those who were hoping for something bad! :)

This is normal. It can die at anything below 5% as the measurement is not fully accurate by the nature of batteries and the load you're putting on it varies greatly. This is just one of those things you cannot worry about. At 3%, all it takes is a one second CPU spike to jump the power draw up enough so that the battery is unable to cope, and it goes into a safety shutdown.

Batteries are sensitive, and the percentage is just a good faith estimate. There's no way for your computer to predict the future of what you're going to do with the hardware, so 3% at idle with low brightness may run all the way to 0%, but the next time at 3% if you load a particular web page that spikes the CPU for a second, you've burned a lot more than it anticipated, and it must shut down to protect the battery. If you allow a Lithium battery to drop below safe levels, it can explode, so the safe thing is to make sure it doesn't do that. Just FYI, you're already in the danger zone at 5% - the computer downclocks the CPU and GPU severely and performance begins to suffer so it can preserve the health of the battery. This has been done for years and years.


This is just like the "miles to empty" in your car. Purely an estimate. If you have 5 miles to empty and you decide to drive aggressively or have to climb a steep hill, you're going to deplete the tank almost immediately and you won't get your "promised" 5 miles of remaining fuel.

lol. it depends on how and what you are working on. Any notebook will shut down around 3-5%.

I would never run down mine to 3%. Always plug in around 20-30% . So it is normal. Nothing to worry about.
