I was thinking that the S5 was charging a lot slower than my S4. I was always amazed at how fast the S4 would charge with phone on like from 1-100% in about 1.5 hours. The S5 is taking about 3 hours from say 1-100%.
After checking with GSAM Battery Monitor Pro the S4 was pulling 1900mA of its included 2 amp charger. The S5 only draws 1200mA on the same charger. I also checked the S5 with its included 2 amp charger still just pulling at 1200mA.

I did this on two (2) S5's and two (2) S4's.

I guess some one with a volt meter setup could test this more scientifically but from a real world stand point I notice the difference. Not a hugh deal really as the S5 battery last a lot longer so I guess it balances out if your not charging as many times.

A benefit to this that I've noticed is the phone does not get no where near as hot as the S4 does during heavy use while charging.

Just wondering if kernel apps like Faux or others would be able to increase the draw with like fast charge for those times when running say GPS and music and need to charge?

Battery went completely dead today all the way to shutdown. Plugged it in and restarted it @ 12:40pm. I didn't get back to it in an exact hour (see pic). It was charged to 74% in around 1hr 15min.

With that said. Plus another WIN for the S5 and Samsung. That quick charge technology that was rumored must be a reality if it's charging this fast with little more than a 1/3 less current draw than the S4 (1200mA vs 1900mA).
