VoLTE may offer better audio and battery life for smartphones

The CDMA and GSM standard have both been around for a number of years as the standard in wireless communication. If you’ve made a phone call on a cell phone in the last twenty years or so, then GSM or CDMA were the technology that made it possible. However, new tech known as VoLTE – or Voice over LTE – wants to change that, and it may do so while improving your battery life, and giving higher audio quality.

VoLTE is in many ways a lot like VoIP, except that it utilizes a data connection through LTE spectrum to accomplish the task, rather than the IP protocol. It’s already being implemented international markets, but has yet to be injected into the U.S. despite the huge growth of LTE in the last two years. Slowly but surely though the technology is being tested by infrastructure firms as they prepare to bring VoLTE to the United States, as it really is the long term goal for voice communication. VoLTE offers CD-quality audio to customers by utilizing LTE bandwidth to communicate, much like how Skype has higher quality audio than your average telephone. The service, in testing by Metrico Wireless on MetroPCS, could greatly improve battery performance as well as give all the other benefits promised so far.

Not everyone is convinced though. MobileBurn reports that the testing may be over-exaggerated given the lack of scale. It cites incidents in LTE performance like the HTC Thunderbolt, which while it could argue itself as the first LTE phone, was brutal in battery life. Despite this, Verizon Wireless is already jumping on board and promising a launch by the end of the year and into 2014. The cost, for carriers, however, is significant. While simultaneously adding bandwidth load to their LTE networks, VoLTE will also do away with counting minutes, and instead utilize everything over data. Cell phone plans will essentially become 100 percent data-oriented.

It’ll be at least a year until we see VoLTE begin to roll out across the country with Verizon, Metro PCS, or one of several potential carriers. Between its offer of higher audio quality, reduced energy usage, and the end of counting minutes, it certainly is a no-brainer for customers to take advantage of, so long as the price is rig’ht.

The best Google Pixel 8a screen protectors in 2024
A photo of someone holding the Google Pixel 8a.

The Google Pixel 8a is Google's latest smartphone, and while it's not a match for Google's flagship phones, the Pixel 8 and 8 Pro, it's not meant to be. The Pixel 8a is a midrange powerhouse, with the Tensor G3 processor, a showstopping camera, and the advanced smarts of Google's Gemini Nano AI model.

But none of that is worth squat if you can't see it. The display is a vital part of any smartphone, and the Pixel 8a's 6.1-inch OLED panel is a beauty. It has a 120Hz refresh rate, and a much higher brightness to boot, making it the equal of some of the best phones you can grab in the midrange market. But all that tech should be protected. Here are the best Google Pixel 8a screen protectors to keep your phone's screen safe from scratches, dirt, and smears.

Apple made an outrageous change to its new iPads
An official photo of the 2024 iPad Air.

After a year-long drought of iPads, Apple finally revealed the new iPad Air and iPad Pro models during its Let Loose event on May 7. This was a unique announcement because it broke some old traditions; the iPad Air now comes in two sizes: an 11-inch and 13-inch, just like the iPad Pro. But these new iPads are also breaking another longtime tradition: They won’t come with iconic Apple stickers. Gasp.

According to 9to5Mac, Apple Store teams received a memo where Apple explained that the iconic Apple stickers won’t be included inside the boxes of the new iPad Air and iPad Pro. The reasoning? As part of Apple’s environmental goals, it is trying to ensure that its packaging is completely free of plastic.
