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. Most people go for a bigger SSD to off set the lack of RAM given the costs.I have a Macbook Pro 13" since Feb, 2016 and all these years it has been a fantastic mac !

You’ll need to price out how much you are willing to spend. Lets get a handle on how it is performing. There is no better display, it is what it is! Just like the logic board issue above they can be hard to find. Review this great guide: The Ultimate Guide to Apple’s Proprietary SSDs and here’s the drives Samsung SSPOLARIS PCIe 3.0 x4. FYI if power consumption is an issue you’ll want to get the original Apple SSD. I would look at getting either a 480 GB or1 TB version MacBook Pro and MacBook Air (Mid 2013 to Early 2015) Blade SSD Upgrade Bundle. You only have a few choices as these systems use a custom Apple SSD.
Replacing the fan should only be needed if cleaning the dust build up didn’t help and the fan was making noise (bearing gone).Ī cheaper upgrade would be getting a new SSD. Cleaning off the old thermal paste and applying a fresh coat also makes sense. I would clean the dust out using a soft paint brush and a can of can’ed air.
