Hi; I have got rMBP 13 inch Early 2015 base model. Now my understanding is/was that the battery life on new machines is suppose to be around 10 hours, at the least. However, my machine consumes around average 10% per 30 minutes, lasting more or less just 5 hours. This is happening even when usage is at the very minimum (i.e. Just using Apple's PAGES). Presently I use my rBMP usually for typing only, followed by some browsing, and occasionally for watching movies. Only 3rd party apps on my rMBP are Skype & VLC. No add-ons for Safari either; though, I did update it to 8.0.6 and it keeps showing up in the list of apps that may be using significant energy now and than. But the issue has been there even before Safari's latest update. Anyway, anyone who has bought similar machine recently (& those who are knowledgable) can kindly inform me: 1. How much avg. battery life they get?, especially during minimum usage? 2. What amount of 'time-remaining' does their battery icon shows at full 100% charge? I didn't notice if I had better battery life before I updated the OS to 10.10.3. So, I can't even say if its the result of Yosemite's update. I did reset the PRAM and recently the SMC as well. Prior to the reset my battery showed more or less 5 or 6 hours remaining. After the reset the battery time remaining fluctuates between 7 to 9 hours. The first % (or the 100th %) also seems stable to usage, lasting almost 10 minutes or so. However, counting down from 99th % the battery goes down quickly to 4 to 5 hours both in terms of time-remaining stated by the rMBP & by actual usage.
