Which display saves Battery life: AMOLED or LCD?

Often the question of “Which smartphone do you advise me that will saves battery life,” becomes very complicated, because each battery lasts depending on the type of use that we make of it. Anyway one of the most frequently asked questions is "How to saves battery life of our smartphone?" and, as the usual advice can be helpful, now we show you another reason why the life of our battery can be slightly elongated.

The issue is particularly also because the main culprits of poor battery life are the displays of smartphones that, depending on the model, can be LCD or AMOLED (including the main). What are the differences?

AMOLED vs LCD: Who consumes more battery?

Despite the eyes of the inexperienced may seem the almost the same and the same thing, but between AMOLED and LCD there are net differences:

LCD Display: This type of screens mounted on many of the Android devices on the market, when it displays an image, not reflected by its own light but uses that of panels placed under them. Thus, even a black image, with a display LCD, it shows lit and never darkened, because the panel at the bottom there will always return a light pulse.

Display AMOLED: These displays, however, are more intelligent in that they use their power to provide the image on the screen that then we’re going to look at. The question battery, then, seems to be better with these panels, with a black background, use less energy as each individual pixel will be powered separately.

Essentially, therefore, the trick of the black background is functioning only on devices that mount an AMOLED display (i.e the setting of a screen very dark or totally black to exploit the special characteristic of AMOLED panels), since, as we have already said, a background black could make remain deactivated few pixels and, accordingly, could make us saves battery life up to 6% per hour.

In the smartphone with display LCD, this trick does not work because even with a black background, the panels will always continue to light and, consequently, to consume battery.

Therefore, AMOLED display saves battery life of your smartphone.

【GUIDE】 How to Rip a DVD

Say you have a movie on DVD, but you want to watch it on your phone, tablet, somewhere else. You can "rip" that DVD—or turn it into a movie file on your computer—to play it wherever you want. Here's how to do it.

Ripping a movie to your hard drive can seem like a complicated task, but it's actually pretty simple. There are a lot of ways to do it and a lot of different programs out there, but our favorite method uses a program called Handbrake. It's easy to use, it's available for Windows, Mac, and Linux, and it'll convert your file into compatible formats for any device, like an iPad or Android phone. The video above should walk you through the process, but you can follow along with these instructions.

1. Head to Handbrake's homepage and download the program. Install it to your computer as directed.
2. By default, Handbrake can rip unprotected DVDs, but most DVDs you buy from the store have copy protection. To get around this, you'll need to install libdvdcss. On Windows, you can download this file separately (for 32-bit systems and for 64-bit systems), rename it to libdvdcss.dll, and put it in your Handbrake program folder (C:\Program Files\Handbrake). If you're on a Mac, download this file and double-click to install it.
3. Insert the DVD you want to rip, and open Handbrake.
4. Click the Source button in the upper left-hand corner and choose your DVD drive from the list. It will start scanning your DVD, which could take a few minutes.
5. When it's done, head to the "Title" drop-down menu in the upper left hand corner of the window. This is where you'll select which part of the DVD you want to rip. In the case of movies, it's usually the longest title, so just pick that one. If you're ripping episodes of a TV show, it's usually the 22 or 44 minute ones, and you'll have to rip them each separately.
6. Click the Browse button on the right side of the window. Navigate to where you want to save your movie file, and type in a file name in the box. Click OK.\
7. Next, head to the bar on the right labeled "Presets". This is where you'll choose what format the resulting file will be in. If you just want to watch it on your computer, the "Normal" or "High Profile" preset is fine. If you want to watch it on something like your iPod or iPhone, though, pick the correct preset from the list.
8. Hit the Start button at the top of the window. This will take awhile, so you'll probably want to grab a cup of tea.
9. When it's done, you'll get a popup notification. From there, you can double-click on your movie file to watch it, or sync it to your device of choice. Enjoy!

It seems like a lot of steps at first, but it really isn't very difficult—especially after your first time through. Once you've installed the libdvdcss file, for example, you can skip that step in the future.

It's just a matter of picking the right chapter from the DVD and ripping it to the right format. Note that if you're going to be ripping a lot of DVDs, you can head to Tools > Options (or Handbrake > Preferences, if you're on a Mac), and hit "Browse" next to "Default Path" to choose a location for all the other movies you rip in the future. You can also click "Add to Queue" instead of "Start" and rip multiple files at once, which is great for ripping TV shows.

Good luck and enjoy your newly ripped DVD!
