Question: Apple 5w vs 10w & 12w Charger for iPhones

[iRobby]

1) I was wondering if using a 10w or 12w Charger improves the charging time over the 5w Charger on an iPhone 6 Plus?

2) I was wondering if using a 10w or 12w Charger improves the charging time over the 5w Charger on an iPhone 5C?

I have been doing exactly this with all my Apple devices over time.
I used the 85W MBPro charger instead of the 60/45w MB / MB Air charger as well as the the 10/12W chargers of the iPads for all of my iPhones (3GS,4,5)

1) Yes, it greatly decreases your charging time.
2) It is even safe to do so.

I know it is safe on the iPhone 5c but does it decrease the charging time as well? If not then I won't waste my money on a 12W for the 5c and use the 5w.

From what I remember from several other recent threads on this here it's only the 6 and 6 plus that benefit from faster charge rates, the older phones charge the same.

I do this with iPhone (past and present 4, 5 and now 6), MacBook Pro, iPad.

Yes, charge time is much, much faster. But, I wonder how this effect long term battery life. Does it wear out the battery any sooner than the slow charging of the lower wattage chargers?

I replaced some duplex receptacles in my house with the new ones that add 2 USB charging ports to them. I plug in my iPHone, iPad and my wife's LG phone every night.

I know they are safe. But am I shortening the long term battery life?

All my phones (3GS, 4, 5) charge(d) considerabely faster! It won't "wear out" the battery faster.
1) Apple explicitly used to allow/recommend this procedure.
2) Also considering the higher wattage it is even safe to do so.
From a physics point of view-- the only thing that you might notice
is, that the charging device (phone) will get warmer than with the lower wattage. Most people are afraid that there is also a higher voltage that charges the device (which could actually be harmful), but Apple used to put several power transformers in one charger, so that you were able to use them completely interchangeably .
