An analysis of smartphone charging times comparing the Apple iPhone 6, Samsung Galaxy S6, LG G4, Motorola Droid Turbo, Google Nexus 6, Asus Zenfone 2, and HTC OnePlus 2 has been published by Tom's Guide.
Here's how the tests were performed:
To test each handset, we ran it down until it was powered off. Then, we charged each device back up to 5 percent. This put all of the phones on an even playing field, as some don't power down until the battery is completely dead and others cut out when there's still 3 percent or more battery remaining. Once each phone had reached 5-percent battery life, we plugged them in and started the clock. We then noted the charge of the battery at 5 minutes, 15 minutes and 30 minutes. Finally, we noted how long it took to charge the battery, first to 80 percent and then to 100 percent.
The Asus Zenfone 2 led the pack initially charging to 17% in 5 minutes, 32% in 15 minutes, and 53% in 30 minutes. Compare that to the iPhone at 6% in 5 minutes, 20% in 15 minutes, and 36% in 30 minutes.
Examining the time it takes to reach 80% and 100%, the Galaxy S6 comes out on top reaching 80% in 48 minutes and 100% charge in 1 hour and 22 minutes. The iPhone 6 comes in at the bottom of pack taking 1 hour and 15 minutes to reach 80% and a lengthy 2 hours and 35 minutes to reach 100%.
Considering that each phone has a different size battery, the site also calculated milliamps per minute to determine the fastest charging device.
The Zenfone 2 fared the best at the 15-minute mark, with a score of 64 milliamps per minute, and second place went to the Droid Turbo, with a score of 57.2. The Zenfone 2 also won at the 30 minute mark charging at 53 milliamps per minute followed by the Droid Turbo at 49.4. In the race to 100%, the Droid Turbo comes out on top charging at 36.45 milliamps per minute, while the LG G4 (31.25) and Galaxy S6 (31.1) came in second and third.

Yeah! I’m digging my S6!
Same here.
Ping to ThunderSleeps, Dayglored, and Shadow Ace for their lists as well.
If you want on or off the Mac Ping List, Freepmail me.
Me, too.
Who buys a smartphone based on charging time?
Does it give bragging rights? I guess.
But, so what?
As long as the phone gives you a full day of usage before requiring recharging....and can recharge while you recharge (sleep)....there is no problem.
Battery capacity matters as well.
My phone has a 3,400 mAh battery and it takes longer to charge than, for example, a 2,000 mAh battery, but it also lasts a lot longer.
LOL @ this chart and your S6
Comparing percentage of charge would be valid if each phone had the same size battery.
My Droid Turbo has a ridiculous 3900mAh battery which is
50% bigger than the S6.
I forgot to charge my phone last night. Still had over 50% when I got up.
I’m more interested in which one has the best (non-wifi)reception. My Note 3 was lousy! When it actually had 4G it was screaming fast but 90% of the time it was 3 or even 1G.
Since it was broken on Monday, I am in the market to replace it.
BTW, Assurion Warranty now wants $150 to replace it and that bites as I was told when I bought the phone (outright) it would be $100. (insert mad face here)
I have a mid-range LG-G Stylo and It will easily go more than a day with constant use. It will go more than a week just sitting on the counter turned on.
Phone had a good price and runs Android lollipop.
I saw an ad in a Verizon store window for a phone advertising a battery life of 48 hours. Don't remember the brand name of the phone and this might be a gimmick, but if I could get a phone battery to last just one day, I'd be a happy camper.
My Asus ZenFone 2 with 4 GB RAM and 64 GB storage charges DAMNED Fast ... maybe 30 minutes for a full recharge ... ... I love it ...
It connects to the Internet is a fraction of a second — Facebook loads before I can blink my eyes...
Fast charge and fast machine.
Might be important if you have to frequently recharge through the day. I plug my iPhone 5 in at night, and using an iPad charger it is 100% very quickly. If I have bluetooth off I charge it every other day. With bluetooth on all day I still have between 25% and 50% power at the end of each day.
Faster charging lowers battery life. Since iPhones cannot easily change batteries, they are designed to charge slower.

IMHO these three comments pretty much cover the waterfront. Swordmaker's iPhone very well might give a shorter lifetime because of the use of a higher capacity charger.I confess to an incomplete understanding as to how a higher capacity charger can work without imposing a higher voltage on the battery. I would assume that it has lower internal resistance, but that would only say that the the voltage doesn’t drop as much from its nominal value under load.
"Milliamps per minute" is an almost meaningless unit of measurement, which suggests that the people doing the measurement were not very savvy in their knowledge of electronics.
Milliamps itself is a measurement of charge flow per unit of time, so milliamps per unit of time would be what, a measurement of the acceleration of the flow of charge?
It reminds me of all of the solar power "experts" who talk about "kilowatts per hour" when they should be discussing "kilowatt hours". It makes a difference.
But that's all mathy and sciency and stuff, which is much too hard to understand (said Barbie)...
Not all chargers are created equal. My 5s charges lickity split on some chargers and not on others. The best is my cheapo from Monoprice.com. It will charge up in less than an hour for one device, add another and the 2.5 amps goes to 1.25 for each.
USB smart charger’s are also regulated by the chargee changing the amp load to regulate heat. There is a lot more to consider other than just time.
Idiots. The SONY Xperia Z3 with the QuickCharge 2.0 adapter charges to 35% in 5 minutes, half the time of their “champion” Asus.
Whats a smartphone? My cell phone can’t even take a picture :<((( But I know what TCP/IP is.
It is current that recharges batteries, so a charger capable of providing a higher current will charge a given battery faster. For Lithium batteries, a constant current is required, so the applied voltage will change as the battery charges to maintain a constant current.
Heat is what kills batteries, and faster charging at higher currents produce more heat.
