I don't know a lot of details about battery specs but I gave up on PC's a long time ago ..... the MacBooks just perform, seldom ever glitch or crash, they don't ever seem to get bogged down by internet use. Of course they do integrate with iPhones better than Android. I would get a MacBook loaded up with the most features you can afford ..... you will be good for at least 7-8 years. The downside is, at that point, the machine will still be working great but probably won't support their newest OS.
