Laptops Arena

When MacBook Pro 17” was first released it came on the market with sealed batteries system; now this feature belongs to the smaller versions - new MacBook Pro 13” and 15”. And according to the tests performed by Walter Mossberg the battery seems to be good enough to count it among the best features of the recently released MacBook Pro – 15” and 13”.

Here is a summary of these tests.

It is a fact that most of the customers to own a laptop never use the possibility that removable batteries offers you, meaning to buy a fresh spare one to replace the old between charges. According to NPD estimations, barely a 5% of the users buy a spare battery, so as a result a new trend emerged in the industry: more electronic producers started to build their devices with the rechargeable batteries sealed inside. The company which adopted this trend is Apple, that it is known to adhere each time to new trends, maybe at a faster pace than any other companies in profile. As such, when the new MacBook Pros 15” and 13” were released they came with higher capacity, sealed-in batteries. Including the batteries in the device allows the producer to create bigger ones, with higher capacity (this one has grown between 33% and 46%) and at the same time they don’t present the risk of hefting the device. On top of it Apple declares that the software technology available on the device confers the battery a 5 years life-time.

The two laptops revealed the fact that the batteries meet Apple’s claims that they last seven hours between charges, almost a full time work without any plugging. In this case purchasing spare batteries seems futile. There are however some aspects left to measure; for one is the Apple’s claim that they last up to 1,000 charging times, meaning the 5 years life time duration of such battery. Secondly, the guarantee terms are not very clearly specified, for instance if the battery doesn’t prove to hold an adequate charge, what then? Apple says that the company allows you to replace it at a price that normally costs the rechargeable one, but this is not to be verified yet. And another aspect that needs to be considered is the case of the users that need the device mostly on their long travels by the planes, and a replaceable battery seems to be a must. And this option for the new MacBook Pros is unavailable, unfortunately.

At turned-off power-saving features, with Wi-Fi network on, a maximum screen brightness and continuous music play, the test revealed that the MacBook Pros both didn’t use the energy-saving, and a less consumed power due to the use of integrated graphics chips. But either way, the results lead to the same conclusion: Apple managed to produce MacBook Pros’ sealed batteries of larger size and life as well, without extra-weight of the device and we just need to let the time pass and see if these batteries last indeed up to 5 years. But who knows what other new laptops will meanwhile emerge on the market?
