Is this really true about battery?!

[Iphoneattack]

That after 300 cycles it drops down to only 50%??

If my iPhone 4s just reaches 6 hours a day, does this mean after a year it will barely last me 3 hours a day?

If so, is there a way of changing the battery to a new one if my battery drops 50% in the next year?

I don't see any screws on the back?

300 *full* charge cycles, unless your phone is going to 0% every day, you won't be doing 300 in a year, partial charges are partial cycles, and I think it's supposed to be more like 80% after that isn't it?

I thought that it's supposed to be 80% after 300 cycles, not 50%. And if you think the capacity will really drop that much, great news - as Apple offers 1 year warranty on new iPhones, if they determine your battery has a capacity less of what it should be, they may replace the phone.

Here's the even greater news: A battery costs $7 and takes 2 minutes to change.

Actually, the correct figure is 80% capacity after 400 charge cycles.

Yes, partial cycles are cumulative. So 10 days of 10% discharge equals one full charge cycle.

Ah the joys of having an iPhone with phillips screws holding the back case on My battery is fine however if it ever goes kaput, I'll be replacing mine the easy way.

I've had an iPhone 4 since launch and not noticed any drop in battery life yet. If you are only getting 6 hours you must be spending all day on the iPhone playing games or watching video.
You can always get a case with a built in battery. Check out ipower up cases. They double your battery life.
