    I have the 2015 Macbook 12" with 247 charge cycles. I've powered the laptop using Anker PowerCore+ 26800 and a USB-A to USB-C anker cable.

    I noticed the 'service battery' warning yesterday and I want to see if this issue was caused by the Anker battery. I am not sure if it has been there for a while. It is the first time I noticed the warning.

    I had the Anker battery connected to my laptop and an iphone 6s and I wonder if this could have caused damage. I want to make sure the Anker is not damaging the battery.

    I tried reset smc/pram several times but that did not do anything.

    I have applecare warranty. Do they replace battery same day or ship it out?

    Thanks.

    I think it was you asking this at DPR where I have just replied! No problem!

    You said there that your battery health was 75% which I think is low enough to trigger the battery warning.

    I'm sure AppleCare will replace it but don't know how long it takes. Last time I used AppleCare my MBP was picked up on Monday and returned Friday with a new logic board. AppleCare used a third party epairer in the UK to do this.

    As I said there I dont' believe the Anker is a cause of the problem. I use a RavPower 30W battery without problems.

    If you use batteries you might be interested in this thread:

    Hi,
    I saw the thread on dpreview also.
    I do have and use the same Anker battery pack to charge my 2016 macbook and some other devices also.
    No problem at all.
    It seems that your macbook battery just gave up. Hope apple to fix it for you!
