Hi We have MacBook Pro which has just used 55 cycles! from yesterday I see my MacBook going to sleep exactly on 45% Take a take look here:

https://www.imageupload.co.uk/images/201… I believe maybe this is a software (OS) problem ? At the moment I have typed this question on battery the battery indicator hanged on 100% after maybe 2-3 hours later its will start countdown 99 98 97 ….. till 44%. IMPORTANT: After fully charging I have reset SMC and I see my MacBook is again charging! Is there possiblity this is software or OS problem? Maybe they are confusing to counting % of battery Update (09/28/2017) Hi here new screenshot from CoconutBattery lets explain more : my macbook for 2-3 hr hanging on 100% ( not counting ) after 2-3 hr its counting to 55% and THEN going to sleep. i believe battery working fine because ,Battery Percent its hanging on 100% for 2-3 hr , after 2-3 hr its start to counting 99 -98-97-96…. till 55%

First I would start with reviewing the MagSafe charger and it’s cord. Review this Apple T/N: Apple Portables: Troubleshooting MagSafe adapters also make sure you have a real Apple MagSafe adapter some cloned units can damage your Mac and just don’t work correctly. Here’s a good write up Why you shouldn’t use Cheap MacBook chargers Next you should review your energy settings: Use the Energy Saver settings on your Mac And lastly, make sure you have calibrated your battery following this guide: How To Calibrate a Mac Laptop’s Power System Update (09/28/2017) If you checked the MagSafe chargers cord and the connection and found no problems then I suspect the battery has an issue here. Is this the original battery or a new battery?

Hi Masoud! Did you solve the issue with your battery? Hope you did! I have the same problem with my macbook pro 2017, and I’m in Argentina right now with no possibility to access to apple service. If you solve it please let me know how. Best,
