Free group messaging. It's like a private chat room for your small group. Have as many as you want, and it's always free. Now, you can coordinate with coworkers, organize a game night, and keep in touch with family all in the same place.
Contrary to what you might think (or have been told), leaving your phone or laptop plugged in all the time is not bad for its battery. That's because your gadgets, the batteries in them, and the chargers you attach them to are actually pretty smart about the way they do business.
This is a result of using the phone while charging often. I hope this helps with your question! I don't know that using the phone while you charge the phone will harm it. But I do know that leaving the phone on the charger after the phone is fully charged will eventually ruin your battery. Even if people say that doing this does not matter anymore with smart phones.
