Apple has to work carefully to balance performance with battery life. Competing devices from companies like Samsung do offer more RAM, but at the cost of performance. Samsung's Galaxy S5, for example, offers impressive battery life at up to 10 hours of Internet browsing and 12 hours of HD movie watching, but it appears the iPhone 6 Plus may exceed that, based on battery information unveiled during the keynote.
What a load of steaming crap. The Note 3 has 3GB of ram yet gets better battery life than the Galaxy S5 with 2GB per Laptop Mag battery test. The Note 3 got 11 hours and 15 minutes and the S5 got 9 hours and 42 minutes; almost 90 more minutes. Its all about battery capacity and cpu technology. Never heard of ram being a huge factor in battery life. Some additional drain; sure because you have extra circuits but not enough to see a huge difference.
Even the Note 4 with only 20maH more is expected to get 30% more battery life with the same amount of ram. Its all about using an efficient cpu. And the Note 4 charges faster than the Note 3 which is pretty quick in its own right.
And I would figure you would compare the battery life of the Note 3 or 4 to the iPhone 6 plus considering the phone is just as big; not to the S5. On top of that we havent seen real world battery test yet. Is this some kind of damage control???
