Q: Rapidly decreasing battery health on 2015 rMBP?

Hello all, I'm starting to worry a bit about my battery capacity vs design capacity on my retina macbook pro 13". It's a early 2015 model that I bought in March. I know that Apple guarantees the battery will have at least 80% of it's design capacity after 1000 cycles, but I'm worried mine is going to fall far short of that. Here's my battery info:

Here's my usage habits: I usually charge it when it's around 30%, but recently I've used my computer a lot that the charging threshold dropped down to 10% , so I mostly charge now when it's at red critical levels. I play games like Minecraft and Watch Dogs (on Windows partition), and also some Android games with an emulator like Fifa 15 and Real Racing 3. These games all drain my battery. My computer used to fluctuate between 88% and 92% but now it's changing between 83% and 84%. Have I inflicted irreversible damage to the battery. Right now, I still have my warranty, and I think it's also covered through the screen coating replacement program.

 

I leave it off the charger quite a lot. If it's not increasing, do you think I should check at the Apple Store? I also have quite a few problems with my laptop as well, including creaking when I press on different parts of the case, a cracked "X" key, and the screen coating is coming off as well.

 

 

Any thoughts? Thanks!

MacBook Pro (Retina, 13-inch,Early 2015), OS X El Capitan (10.11.3)

    You're using a third party application to check the battery, try comparing it to the information in System Information.

    If you want to prolong the life of your battery trying using the computer when connected to the power adapter as much as possible.

    Yes, your MBP is still under warranty so take advantage of it.

    Incorrect,.  Apple says the battery is 'designed' to reach 1000 cycles at 80% of original design capacity.  There is no guarantee that it will and most batteries will not.

     

    Ciao.
