Does the iPhone have a 300 recharge cycle battery?

post #1 of 5
Thread Starter 
Someone showed me a review today that shows the iPhone just can be charged 300 times. Is that true? I'm hoping to have iPhone 2.0 within a year but this just doesn't sound nice. I know the replacement is $85 and it's not user replaceable but that sure is a short battery life. I know with most battery technology they often last 2-3 years.

What is the best way to get maximum battery life? The guy that showed me the review just runs his battery down each time and often goes over 2 days between charges but I charge mine nightly and this is important to me since I want to be able to sync it daily. Most of all, is there any truth or this or estimates? I know maybe we'll only know in a year when we see how battery life is or how much it's shortened.

The reviewer is an idiot.

Check the Apple website. 80% capacity after 400 cycles.

A charge cycle is not the number of times you connect your iPhone to a charger. A charge cycle is complete charge/use. So for instance, you fully charge your phone. You use it for the day, and by the time you get home, you have 50% battery left. You stick it on your dock for the night so it recharges to 100% and re-syncs. Next day you take it to work, like the first day, you use 50% of the available charge. You have now used 1 charge cycle (50% yesterday, 50% today). Theoretically you could use 10% per day and recharge every day, and you would not use a full cycle until the end of the 10th day.

Also, like they said above, it doesn't stop working after 300-400 charge cycles, it just has diminished capacity.

This is exactly my scenario.
Using approx 50% of battery capacity every day and just top off each night.
In this scenario my phone should still be perfectly functional in two years.

Historically I get a new phone every 12-24 months anyway, so am not sure what all the fuss is about.
It is just FUD from Steve Balmer and friends.

having to replace that battery every 10 months would suck
