WEBVTT 00:00:00.240 --> 00:00:06.400 Cell phone chargers. They're all basically the same, right? You plug it into the wall, you throw a USB cable on 00:00:05.040 --> 00:00:10.080 it, then you plug it into the the lightning or micro USB or whatever other 00:00:08.240 --> 00:00:14.160 connector there is on your phone and call it a day or night if you charge 00:00:12.480 --> 00:00:20.560 your devices at night, which would make sense because well, look, never mind that. The point is, easy, right? Wrong. 00:00:18.640 --> 00:00:24.320 And you know what else is wrong? Teasing upcoming videos like part five of whole 00:00:22.640 --> 00:00:29.350 room water cooling when realistically they're at least two weeks out. And yet, 00:00:26.560 --> 00:00:34.559 I'd do it anyway. 00:00:34.559 --> 00:00:40.399 Cooler Master's Casemod World Series is your opportunity to show off your 00:00:38.399 --> 00:00:46.079 modding skills and win great prizes.

So, four years ago, 00:00:46.079 --> 00:00:52.879 life was relatively simple, at least as far as 5V chargers for phones and 00:00:50.640 --> 00:00:58.000 tablets went. You had your USB ports on your computer or very low-end wall warts 00:00:55.360 --> 00:01:02.399 that output 500 milliamps. the typical ones and the ones bundled with your 00:00:59.600 --> 00:01:06.560 phones which were usually 1 ampish and premium aftermarket ones and the bundled 00:01:04.479 --> 00:01:11.080 ones with tablets which were usually two or 2.1 amps. Now even in those days 00:01:09.439 --> 00:01:15.200 though you sometimes needed interoperability between your charger 00:01:13.040 --> 00:01:19.040 and the device being charged in order to take advantage of the best possible 00:01:16.880 --> 00:01:23.439 charging rates because beefier componentry is required to prevent the 00:01:21.360 --> 00:01:27.200 device and/or its battery from being damaged by the charging process. So 00:01:25.439 --> 00:01:31.680 phone manufacturers like Apple and Samsung used little signaling tricks 00:01:29.600 --> 00:01:35.600 that would allow their chargers to communicate with their devices to let 00:01:33.520 --> 00:01:40.119 them know, hey, it's okay to draw more power. Fast forward to 2012 and the 00:01:38.000 --> 00:01:45.280 introduction of Qualcomm Quick Charge 1.0, an attempt to standardize faster 00:01:43.280 --> 00:01:48.320 charging so more customers could leverage it, at least those customers 00:01:47.040 --> 00:01:54.079 whose phones contained Qualcomm processors. Version 1.0 to was all about 00:01:51.360 --> 00:01:59.119 optimizing charge times with 5V 2 amp adapters that you already owned with a 00:01:56.399 --> 00:02:03.600 fancy power management IC built into the device itself. All the user needed to 00:02:01.520 --> 00:02:08.800 know was that his or her gadget was charging faster, especially when it was 00:02:05.840 --> 00:02:13.680 very low. Version 2.0, 0 which started showing up in devices like the HTC 1M8 00:02:11.120 --> 00:02:19.280 in early 2014 takes the ondevice hardware a step further and allows it to 00:02:16.000 --> 00:02:22.000 accept up to 3 amps from a 5volt power 00:02:19.280 --> 00:02:29.280 supply and even other voltages as well up to 12 whoops volts. But the tricky 00:02:26.480 --> 00:02:34.239 thing is that while both the devices and the chargers are backwards compatible 00:02:31.440 --> 00:02:38.720 with older lower power ones to take full advantage of quick charge 2.0 0. We need 00:02:36.800 --> 00:02:44.239 drastically different power sources that can deliver the aforementioned greater 00:02:41.280 --> 00:02:48.080 current and varying voltages. So, if you want to be sure it supports quick charge 00:02:45.920 --> 00:02:52.800 2.0, check the box. It'll say quick charge 2.0 and it'll come with a pretty 00:02:50.400 --> 00:02:57.200 steep price tag for up for a freaking wall wart. So, the question then is, is 00:02:54.720 --> 00:03:02.879 it worth the investment? Well, Qualcomm claims that compared to conventional 00:02:59.360 --> 00:03:05.760 charging, so 5V 1 amp, quick charge 2.0 00:03:02.879 --> 00:03:11.440 0 can fill your battery up to five times more in the same time. And even compared 00:03:08.239 --> 00:03:13.760 to Quick Charge 1.0, it's twice as fast. 00:03:11.440 --> 00:03:17.920 But their results, while surely very scientific, were done on a bare battery 00:03:15.920 --> 00:03:22.000 as far as I can tell, and therefore might not really reflect exactly the 00:03:20.080 --> 00:03:26.319 results we'll see in the real world. So, I brought this test to the real world, 00:03:24.000 --> 00:03:31.040 suckers. I used a Nexus 6 from Google, manufactured by Motorola, and tested it 00:03:28.480 --> 00:03:35.760 in four different scenarios. First, with an Apple 1 amp charger that I've had 00:03:32.959 --> 00:03:40.799 since I got my iPhone 4. Second, with a 2 amp wall wart that I got with the 00:03:37.440 --> 00:03:43.280 Samsung Galaxy Tab 10.1. Third, with the 00:03:40.799 --> 00:03:48.560 quick charge 2.0 charger included in the Nexus 6's box. And finally, with a 00:03:46.319 --> 00:03:52.640 third-p party quick charge 2.0 0 charger from Pure Gear to see if the rated 00:03:50.879 --> 00:03:56.879 current at the various charging voltages makes a difference on this device anyway 00:03:54.879 --> 00:04:01.599 since they're actually a touch lower than Motorola's bundled turbocharger. 00:03:59.439 --> 00:04:06.360 Maybe that contributes to Pure Gear's smaller size as well, actually. Now, 00:04:04.319 --> 00:04:11.360 before beginning, I needed a testing methodology. Obviously, I couldn't just 00:04:08.879 --> 00:04:15.200 power down the phone and plug it in and stare at it until it was finished. So, 00:04:12.799 --> 00:04:19.600 here's what I did. I ran a 3D game with the flashlight on to drain the battery 00:04:17.440 --> 00:04:23.280 until the phone powered off. Then I plugged it in briefly, powered it back 00:04:21.440 --> 00:04:27.600 on, and let it sit at the home screen until it reached 3%. Any lower and it 00:04:25.919 --> 00:04:31.680 would shut down again. I put it in airplane mode and closed all apps except 00:04:29.759 --> 00:04:35.600 for battery monitor widget, which I configured to pull the battery level 00:04:33.280 --> 00:04:40.400 once every minute. Because a big part of the benefit of quick charge is not 00:04:38.000 --> 00:04:45.440 necessarily the overall charge time to 100% but rather the charge time to go 00:04:43.040 --> 00:04:49.600 from empty to a reasonable level when you're desperate. And we need more plot 00:04:47.440 --> 00:04:53.919 points than just start and end in order to get that. So to ensure we were 00:04:51.520 --> 00:04:58.960 getting the best possible experience, a 1 ft microB USB cable was used since the 00:04:57.199 --> 00:05:03.759 cable length can have an impact on charging power. And I ended up with the 00:05:01.840 --> 00:05:07.039 graph that you see here. Each charge test was run twice to ensure that 00:05:05.360 --> 00:05:11.039 nothing weird happened. So, I consider these results accurate to within plus or 00:05:09.199 --> 00:05:16.080 minus a few percent. And overall, I learned a few things. Number one, quick 00:05:13.919 --> 00:05:20.720 charge 2.0 is faster than other solutions. Number two, most 2 amp 00:05:18.800 --> 00:05:25.120 chargers out there, you can see I have quite a few of them here, are either 00:05:22.639 --> 00:05:30.479 incapable of handshaking with many devices and enabling faster charging 00:05:27.440 --> 00:05:33.520 rates, or they just plain suck. Most of 00:05:30.479 --> 00:05:35.840 them topped out around 1.5 amps. Number 00:05:33.520 --> 00:05:40.320 three, all the 1 amp chargers I have lying around deliver more than 1 amp, 00:05:38.160 --> 00:05:44.880 including the Apple one that I used for my benchmarks, which was the closest to 00:05:42.320 --> 00:05:50.000 1 amp out of the bunch. And number four, thanks to Qualcomm standardizing this 00:05:46.800 --> 00:05:52.000 stuff, a third-party quick charge 2.0 00:05:50.000 --> 00:05:56.560 charger will deliver basically the same results as a firstp party one, something 00:05:54.320 --> 00:06:01.759 that hasn't always been the case in the past with proprietary standards. So, 00:05:59.680 --> 00:06:05.080 Cool Beans, faster charging is good, right? I mean, it's not quite as fast as 00:06:03.360 --> 00:06:10.560 I was hoping, but it's definitely faster. Actually, not always. It's great 00:06:08.880 --> 00:06:13.520 if your phone is almost dead and you've got a blind date in half an hour and you 00:06:12.160 --> 00:06:16.880 need to make sure you can, you know, text your friends from the dinner table 00:06:15.440 --> 00:06:21.280 if it's not going well. Or if it is going well, he's so wonderful. Uh, but 00:06:19.280 --> 00:06:26.000 juicing up your battery with a higher current charger generates more heat, 00:06:23.840 --> 00:06:30.240 which can negatively impact the battery's overall lifespan. how many 00:06:28.560 --> 00:06:34.160 charge and discharge cycles it can handle. And given that so many batteries 00:06:32.000 --> 00:06:38.400 are non-replaceable these days, this is a bit of a concern. So, whenever you're 00:06:36.479 --> 00:06:43.520 plugging in for the night, even though you have support for quick charge 2.0, 00:06:40.720 --> 00:06:46.800 I'd recommend sticking with a lowspeed charger.
