Slower Charge Times on Public Beta?

I experienced the same thing. I will wait for a few more charge cycles before making any conclusions though.

 

I can confirm when charging connected to a computer it's much slower.

 

It is important to note that after a major OS upgrade like iOS 9 there will actually be a lot of background services running to complete the upgrade.
In addition, after an upgrade we users will tend to use the device a lot more than usual without realising.

 

What hojx wrote - it's the "Can't. Put. iPhone. Down." syndrome plus all of the background services.

FWIW, I installed Dev B3 OTA over B2 - it was OK. As is my custom with Betas, I wait until late that night or the next day to install a fresh version of the firmware. Both my iPhone 6 and iPad 3 are doing very well so far. Also, I use an iPad charger for my iPhone along with my iPad - soooooo much faster than the stock iPhone charger or a Mac.

 

The iPad charger is compatible and can even charge a phone like the 6 and 6 Plus a bit faster.

 

Nope. That's not how it works. A device "draws" how much power it needs and no more. The power adapter does not "send" it. So a 2 amp charger will only supply what the device is requesting up to 2amps. Perfectly safe to use iPad charger with iPhones. Also the iPhone charger is a 1 amp charger and a typical usb port supplies only 500ma ( 1/2 of that) so naturally it will be slower.

 

iPad charger will charge an iPhone the quickest. And computer will be the slowest. USB computer plug puts out 2.5watt, iPhone charger is 5watt and iPad is 10 or 12watt depending on the iPad you purchased.

 

You mean Watt mit Volt.

They all have about 5 Volt.

 

You are correct, I was thinking watt, but somehow typed volt.

 

Depends entirely on the computer. The USB3 sockets on the front of my tower charge my iPhone faster than my wall plug.

 

That's not possible. USB 3 is 4.5watt. Wall charger is 5watt. Either your wall socket or wall charger are defective then. Computers have the lowest power output, therefore their charge will be the slowest.

 

This is the charge profile of my iPhone 6 plugged into my MacBook Pro's USB 3.0 port.

Isn't the regular iPhone 5 volt wall charger capable of 1 amp? And the iPad one can do even more?

 

You have to take into account the extra operating current.

Sure, but it sounds like the max capable current is at least a bit higher (if not somewhat more with the iPad charger) than the 900 mA max from USB.
