10 Simple Way To Extend iPhone Battery Life

Me and my friend use iPhone and we knows that the iPhone's battery life isn't great. In fact, many users can't make it through a full day without having to plug in at some point. There are a few simple ways to stretch your battery life and make it further on a single charge.

While you may have already heard some of these tips, it's always good to get a refresher.

1. Turn off auto brightness and turn down screen brightness. Screen brightness is the biggest battery drain culprit. If you want to get more time in unplugged, turn the brightness down as low as you can stand. To adjust screen brightness head to Settings --> Brightness --> Wallpaper and adjust accordingly.
2. Turn off your Equalizer. The Equalizer lets you tweak sound output from the music app, but it also drains battery. To switch this off head to Settings --> Music --> EQ.
3. Fetch data less frequently. Instead of having your phone push you new emails every 15 minutes, set it to "manually" or "hourly." This will stop your phone from looking for emails so much, which can drain the battery.
4. Close out apps in the multitasking tray. Apple's iPhone software does a good job at managing the power of apps running in the background so they don't use up a lot of power. But if you're desperate, you may be able to squeeze a small amount of time from your battery by closing all your apps. Double tap the home button, then press and hold any one icon and they will begin to shake. Now tap the red minus in the top right corner of each app until all of them disappear.
5. Turn off Push Notifications. Chances are you have a email account or other app set up on your phone that pushes an alert each time you receive a new message. Turning off the push notifications temporarily will definitely save some battery life. To adjust this head to Settings --> Mail, Contacts, and Calendars --> Fetch New Data and turn off fetching for email. Other notifications can be adjusted in Settings --> Notifications.
6. Turn off LTE/3G whenever you don't need it . If you have an iPhone 5, you have a fast Internet connection called LTE. Unfortunately, it can be a huge battery drain. If you're on an older model iPhone you should be able to turn off 3G when you don't need it or are low on power. To adjust head to Settings --> General --> Cellular and switch them off.
7. Turn off Wi-Fi. If you're not near a wireless network, it's not necessary for your phone to continually search for these networks. Turn it off until you're near somewhere where you want to connect. Also turn off the "Ask to Join Network" option, this will drain battery too. To adjust head to Settings --> Wi-Fi.
8. Turn off Bluetooth. If you're not using it, don't keep it on. Head to Settings --> Bluetooth.
9. Turn off Location Services. A lot of people use their phone as a GPS, but if you don't need directions, turn off location services. It's one of the biggest drains on your phone's battery. You can adjust individual apps that use location if you absolutely need to have this feature on. To fix this head to Settings --> Privacy --> Location Services.
10. Get a Mophie Juicepack. If you don't want to sacrifice any of your iPhone's features, the Mophie Juicepack will double you battery life and save you in a pinch.

PaperTab

There’s a lot of consumer electronics news flooding out of CES in Las Vegas this week, but one of the more interesting technology stories we’re seeing is trickling out of Ontario, Canada, where Queen’s University researchers working with partners in the UK as well as at Intel Labs and Plastic Logic have developed a tablet computer that is both paper-thin and flexible.

And while we’ve seen concept prototypes for flexible e-ink screens and the like previously, what’s most intriguing about the so-called PaperTab is the user interface.

The idea behind PaperTab isn’t to make your iPad flexible, but to rethink the way we use tablet computers--and to make them more like the actual pieces of paper we shuffle around our desks. Designed to work in clusters of up to ten tablets, the user can control various screens at once, with one or more PaperTabs for each app in use.

So you can have several documents or apps running at once and work across several PaperTabs to execute tasks while moving things around between them. You can use several together to make a larger PaperTab display, or shuffle them around like you would actual paper documents. Touch two PaperTabs together and you can swap data between them (this is all far better explained in the video below).

Rather than relying on buttons or swipe gestures, PaperTabs respond to the flexing of the actual screen in certain ways--bend the right side of the display to page forward and the left side to page backward, for instance. And while it feels like this might be easier to master in theory than in practice, the folks in the video demo make it look pretty simple.

But the point is, PaperTabs create a really interesting workflow--something like taking the various windows on your PC desktop and breaking them out on your physical desktop while retaining the ability to quickly move data and programs around from page to page. Figure out how to untether these things from those unsightly cords (they’ll need a paper-thin, flexible battery) and this Queen’s U. team might be onto something here--if not a consumer product just yet, at least a very cool interface idea.

Bionic Eye Vs Human Eye

You are blind but you now have an option to get a chance to see..

Previously blind patients who receive the recently FDA-approved Argus II bionic eye system will regain some degree of functional sight. The retinal implant technology, developed and distributed by Second Sight, can improve quality of life for patients who have lost functional vision due to retinitis pigmentosa, a disease that causes retinal cells to die. But the implant doesn't facilitate a sudden recovery of 20/20 vision.

Just as cochlear implants don’t have the sensitivity to accurately relay the complex mix of frequencies in music, bionic vision through the Argus II will be closer to a very grainy black-and-white film than an HD movie.

The multi-piece system starts with a digital camera mounted in eyeglasses. Images from the camera get translated into data through a miniature computer and sent via wireless transmitter to a computer chip on the side of the eyeball. From there, the chip activates an eyelash-thin electrode array implanted behind the retina, which then stimulates retinal cells to send visual information to the brain.

The eye’s retinal cells, commonly known as rods and cones, are split up into six types of receptors that detect contrast between light and dark, red and green, and blue and yellow. Electrical signals from the retinal cells travel through the optic nerve to the brain to form a complete picture of what the eye is looking at.

Instead of trying to imitate the activity of all six receptor types, Second Sight’s Argus II implant focuses on stimulating retinal cells to show light and dark contrast. For a blind patient using an artificial retina, being able to detect the relative darkness of a hole or an approaching wall is a lot more important to independently navigating than knowing whether that wall is painted red or blue.

In terms of acuity, the patient with the best result went from no useful sight to 20/1260 vision. This ratio means that to get the same amount of information a healthy human eye can discern from 1,260 feet, this patient would need to be standing 20 feet away.

Brian Mech, vice president of business development at Second Sight, reports that in clinical trials, all of the company's 30 patients had some degree of vision improvement after receiving the retinal implant. “Basically they see black and white, shades of gray and they’re getting somewhere between 50 and 60 pixels of information on average,” Mech says.

Mech admits this level of acuity is limited. “It is still pretty poor considering normal vision is 20/20, but it’s pretty amazing when you’re completely blind to begin with,” he says. But he explains that as research and testing continues, there is plenty of room to improve the system’s performance just by working on the external technology. Even color vision is a possibility with improvements to the video processor and wireless transmitter. “I don’t want to make it sound too easy,” Mech says. “There’s a lot of work to be done before we can do color vision, but the good news is that they won’t need a new implant for it.”

Second Sight is currently developing more advanced retinal implants, but the timeline is still unclear. Mech says it will be five to seven years or more before the next generation of implants becomes a reality.
