Please, refer to below link regarding what Apple states about "battery cycles". As a customer when I buy a product, I buy on the specifications that the Company lists (plus the reviews) for it's products because those are the "selling points" towards the customer.
#BUY MACBOOK PRO EARLY 2015 CHARGER MAC#
With the current Mac batteries inside the case it probably would have distorted the case/keyboard/trackpad. It bounced between service battery to normal, but eventually the battery started swelling although it wasn't too bad because that only cause the external plate to push out. Obviously the smart battery system got corrupted. The oddest service battery indicator I ever saw was from my polycarbonate MacBook that went into thermal shutdown and restarted indicating a negative battery capacity. Service battery could be a result of something other than capacity loss.
I just have a below average battery and I'm OK with it since I use it as a desktop replacement where I can move it around the house for short periods of time. It only has about 110 cycles and has never been used in high temperatures. I actually got my MBP where it was showing around 94% battery health when new and now after 5 years it's down to about 81%. There's always going to be some random variation. Capacity can be lost faster or slower than that for any number of reasons including manufacturing variations, environmental conditions (i.e. The number they give of 1000 cycles to 80% battery health is a benchmark or a nominal rating. I went to Apple store today and the person there advised me to visit an Apple Service centre so that it could be further diagnosed, though he himself was surprised that this shouldn't have happened since cycle count is still low after using it for almost 4 years and the battery's performance starts deteriorating only when cycle count approaches 1000.Ĭould you please advise if there are other options apart from resetting SMC / calibrating battery like suggested in few other posts to get rid of this "Service battery" message? I read a few options on internet regarding resetting System Management Controller (SMC), and also to calibrate the battery by completely discharging it after fully charged, and then charging it again after 5+ hrs, but didn't help. The cycle count is 260 and the battery is still able to deliver 6-7 hrs of normal usage when disconnected from Power. I have a Macbook Pro 13" since Feb, 2016 and all these years it has been a fantastic mac ! However, I see "Service Battery" as a suggestion when I click on the Battery icon for last 2 days.
