    Those iPhones were designed to pull more than 1A from the charger. Since the stock charger only supplies 1A, it gets hot (not too much, though) while charging.

    If we use an iPad charger (or any other capable of supplying more than 1A), it won't get hot, but this time it's the iPhone that gets hot while charging.

    Does it mean the stock charger is always being overloaded while charging those iPhones?

    I know Apple lists the iPad charger as compatible with every iPhone on their site. But, is it really safe regarding battery long-term life?

    If Apple lists it as safe, it is. Not because I believe everything they say at face value, but because otherwise their engineers and lawyers wouldn't let them assume liability if it weren't.

    I'm confident that the stock charger supplied is safe and operates within the parameters Apple designed it to operate.

    Otherwise, why supply an insufficient charger?

    As to battery, all I can say is that I have had an iPhone plugged in to charge at night with the screen on for 6+ hours as a night stand/alarm clock since Christmas 2011 and I have never had any battery problems. This was with a 3GS, a 5, a 6+ and now a 6s+.

    The 6s+ has been doing this for almost two years and I routinely go to bed with no less than 75% of charge, depending on how I've used the device during the day.

    With todays modern batteries there is really nothing to worry about any more.

    The iPad charger is the way to go. Rapid charge and get back to business. I have one at my desk that services both my iPad and iPhone depending on which needs the juice more.
