Every presentation/talk is the same thing. When I finish, someone from the audience come to me and ask what is that ‘crazy terminal thing’ I am using, so in order to resolve that problem I decided to create this article explaining this, and now when someone asks me, I just tell them to go to this page in order to find the answer.
Tired of monochromatic bash
My passion for the CLI is not a new thing, I am CLI addicted since I was 12 and my Linux passion started soon. I am at ~ when I use my shell, and I use it a lot, for different kind of operations. About 2 years ago I was tired of
Oh-My-Zsh is an open source, community-driven framework for managing your ZSH configuration. It comes bundled with a ton of helpful functions, helpers, plugins, themes, and a few things that make you shout…

ohmyzsh was initially developed by a Ruby on Rails consulting company called Planet Argon, in Portland, Oregon USA.
I also love design, colors and organization. I think that cool colored terminals are elegant, mature and exposes that you have a superior level of relationship with the tool.
In laboratory tests using a 3300mAh battery, a Quick Charge 2.0™ enabled device went from 0% to 60% charge in 30 minutes, while a device without Quick Charge 2.0 using a conventional (5 volt, 1 amp) charger achieved just a 12% gain in the same 30 minutes.
Although this is a Motorola implementation in MotoMaxx, it’s not Motorola technology. The phone has to be compatible with Qualcomm® Quick Charge™ 2.0, and here resides the secret: it’s a charger that juices up from a maximum of 3 Amps, but the phone must be ready for that. Check the Quick Charge Compatibility list website to find out if your cell phone is there! Some models has the technology built-in, but the manufacturer doesn’t ship the charger with it, the good news is that you can use the Motorola Turbo Charger in any compatible telephone.
I got fascinated since the first charge that I made using Turbo Charger, so I purchased an app called Battery Monitor Widget Pro, which provides me some interesting ‘Willy Wonka like’ statistics and graphics regarding the battery and current charging flow, check this out.
As you can see, the charger delivers a high mA rate, charging the phone from 15% to 100% in 2h6m. Note that besides the charger delivers 3 Amps (3000 mAh) according to it's datasheet, we can see a peak of 2437 mA, I think that happens because the phone is turned on, requiring extra resources to keep itself on; I have to deal with this overhead since I need the app running with the phone turned on to measure, I don't have an external tool to measure it with the phone turned off, feel free to donate me one :). It is also interesting to observe the mA throttling when it reaches 90%, I think it does that because of the temperature, as we can see on the graph below...
Caution: HOT JUICE
In a HOT country like Brazil, this could be very dangerous, since the phone reaches up temperatures like 45°C (113°F). During this test, the air conditioner of the room was turned on, and since is 104°F outside, charging this phone without air conditioner in the room should shorten the device's life. This blog doesn't gives me money, so I won't test that, lol. Probably the phone will see that it's too hot and ask the charger to deliver a low mA rate, I don't know.
This is a charge using a MacBook Air USB port, which in the datasheet delivers 500mA, but the phone eats something like 400mA. Note that it took 7h2m to lift from 8% to 70%. This is very problematic when you are traveling, because give you the impression that your telephone battery is bad because you 'gotta charge it every time'
If you want to discover if your charger delivers what is written in the datasheet, just download this app (it has free version) and measure yourself with your charger. This is also good to debug some power problems in your device, such as ‘why is not charging?’, you will see that not all chargers are powerful enough to feed your device with energy, instead of just keep the battery level.
What is about to come
Over time, more and more portable electronics will support Quick Charge 2.0. Certified adapters will be available from various sources, including pre-packaged with certain electronics, or sold by carriers and retailers. Qualcomm recently selected UL as the testing and certification laboratory for Quick Charge 2.0, offering device manufacturers a single source solution for getting products to market in a timely manner. Only accessories that pass the UL certification process will be authorized to carry the Quick Charge 2.0 logo, assuring compatibility and interoperability.
This led us to another subject regarding charging time and charger quality. It’s really impressive how the charges are fast, but it’s also really impressive to observe how the charger inflicts in the charging time.
You can buy a Motorola Turbo Charger on this link, but there also another charger manufacturers such as Powermod that has products certified with the Quick Charge 2.0; probably when you read this post there will be tons of more models and brands available, just be sure if they are certified before buying.
I have no idea if Qualcomm patented it, or if this technology will be available on Apple devices. If you own an iPhone, this is the wrong blog for you, sorry.
