Serious software problems about the battery.

Dear Community,

I am experiencing some hardships using my macbook pro.

First of all I need to mention that I have already downloaded coconut battery and it says my battery is doing a good job. (786 cycles, 76.4% of the design capacity, no errors)

Meanwhile, months ago the battery indicator started to tell me to service the battery. I did some calibration and reseted the SMC. Besides some other diagnostics, a service would only change my battery. But I don't want it to be changed only if necessary.

So the problem is the following:

1.Battery calibrated, fully charged.

2.Charging cable unplugged.

3.Using it, no problems occur. Let's say use it down to 60% of battery life having left.

4.If i turn it off, no problems occur either, BUT I just put it to sleep mode.

5.Few hours later I wake it up. Indicator says it has around 55% of battery life.

6.As I start to use it a few minutes after it turns completely off, and when I try to turn it on says I cant because the battery is empty.

7.I plug it in, few seconds right after I plugged in as I turn ON the indicator says it's got around 55% of battery.

I guess the battery itself if all right because if I don't put it to sleep, I have no problems at all using it for even 6 hours!

Please, if there is any other method resetting, calibrating the system, tell me, I am so much waiting for answers from more experienced girls and boys out there than me.

On the software side, the best thing to do would be to upgrade to the latest OS if you are not currently on it.

However, from what you have described I do believe it is hardware based and requires a battery replacement. No matter the amount of resets or calibrating you attempt to do, if it is a bad battery the problem will not go away. Many software programs such as coconut battery, etc, are very good at determining whether the battery is bad or not, but there is no program that can determine the condition 100% of the time.

For testing purposes, if you are comfortable with it I would suggest opening the backplate and disconnecting the battery, and then put the computer to sleep while it is plugged in with the charger to keep it alive. If the issue continues to occur, you can confer that it is not the battery that has the issue.

If the computer had told you the battery requires service months ago, it is even more reason for me to believe your battery is bad. Depending on how comfortable you are with fixing MacBooks, a battery replacement on a Retina is hard, but not impossible and can definitely save you some money!

Hope this helped, thanks!
