New MacBook is not having an easy time in the market. It has been panned for its reliance on dongles, criticized for using older Intel Chips, and a significant number of users have reported decidedly substandard battery life while using the system.Apple responded to this complaint by reducing the prices of the dongle and removing \u201cTime Remaining\u201d indicator on laptop\u2019s battery, but this seems not be a permanent or even a solution to those problems because Battery life can not be improved by doing this.According to Consumer Reports, Laptop battery life \u201cvaried dramatically from one trial to another.\u201d they purchased each of its, three machines at retail with no interaction with Apple to ensure that it tested the same machines which are being sold to consumers. The findings of CR are worth quoting directly:The MacBook Pro battery life results were highly inconsistent from one trial to the next.For instance, in a series of three consecutive tests, the 13-inch model with the Touch Bar ran for 16 hours in the first trial, 12.75 hours in the second, and just 3.75 hours in the third. The 13-inch model without the Touch Bar worked for 19.5 hours in one trial but only 4.5 hours in the next. And the numbers for the 15-inch laptop ranged from 18.5 down to 8 hours. Those were just a few of the results; we tested battery life on these laptops repeatedly.Typically, a laptop\u2019s battery life may vary from one trial to another by less than 5 percent. To arrive at our final battery life score we average those measurements together.However, with the widely disparate figures we found in the MacBook Pro tests, an average wouldn\u2019t reflect anything a consumer would be likely to experience in the real world. For that reason, we are reporting the lowest battery life results, and using those numbers in calculating our final scores. It\u2019s the only time frame we can confidently advise a consumer to rely on if he or she is planning use the product without access to an electrical outlet.CR goes on detail how they test and notes battery tests in both shipped version of MacOS as well as the recent 10.12.2 update of OS. There was no change found in performance. The managed to test through even Chrome which has reputation for being a battery hog.Unfortunately, the results are not worthy to compare to the rest of data since the company test with default browser and there is no explanation for why Safari would have such varying results.Something doesn\u2019t add up.According to TechExtreme:Something is clearly broken in Apple\u2019s power management stack. The company removed the \u201cTime Remaining\u201d information from macOS 12.2.2, claiming that providing an estimated Time Remaining was too difficult because of the way CPUs enter and exit power states. This seems rather unlikely, given that Microsoft still manages to give a Time Remaining estimate on Windows 10 laptops, and they use exactly the same x86 CPUs that Apple does. There\u2019s also no reason that Apple couldn\u2019t calibrate its \u201cTime Remaining\u201d metric by basing it on how the CPU transitions in and out of power states over a longer period of time. Over the long term \u2014 and keep in mind that to a CPU operating at multiple GHz, five seconds is \u2018long term\u2019 \u2014 the chip\u2019s activity patterns should average out. Very few people start rendering a mammoth 3D project, switch to aggressive 3D gaming, and then switch back to some light desktop work within 5-10 seconds.CR is a gold standard platform for reviewing products and methodologies \u2013 if they are picking up such drastic problems in MacBook with three different systems, it is a good sign that Apple has a serious problem either they could find or don\u2019t want to admit.
