IOS – Does App Store Review Board allow marking an app free and charging prices some days later

All this hype about how to charge your batteries is blown out of proportion.

Although some batteries (I forget which types exactly) can have longer lives if charged at "optimal" rates and temperatures, the reality seems to be that it does not extend the life by much. One of the research papers I read concluded something like if you charge your device at around 17 degrees from 0% until 75% full you can extend the lifespan by about 1/5 of the total life span.

I have charged my devices for days at a time, and my iPod Nano has been plugged in for months, and holds a charge the same as my other nano (I have two) which almost never gets used and only charged ocasionally.

In conclusion, just do whatever is convenient for you.

EDIT: Here are some links to the apple pages related to their iPhone batteries:

These free apps that you downloaded, did you run the app and buy something within the app?

Nowadays, apps can sell you certain features (like more functionality or tokens in case of games). These purchases are called In-App Purchases (IAP) and they are charged towards your card.

If you downloaded apps or games that have In App Purchases and you want to make sure that you don't make these purchases by mistake (kids make this mistake many times), then go to you iPhone's Settings --> General --> Restrictions --> Enable Restrictions and then under Allowed Content, turn off In-App Purchases. This will stop anyone from spending money.

If, however, you are being charged for the app itself, you should contact Apple support and they will look into the matter and explain what is happening, maybe even give you a refund.
