Chrome 57 to limit power consumption for background tabs

If you use Chrome as your main browser, you’d be happy to hear that the latest version throttles background tabs to prolong battery life on your device.
If you are like me and rely almost exclusively on Chrome, you might have noticed that Google’s browser consumes a lot of battery power. That’s partially due to your background tabs – tabs that are open but aren’t being actively used. In fact, according to Google, background tabs consume “a third of Chrome’s power usage on desktop.” Well, that’s about to change with the latest Chrome update.
In fact, according to Google, background tabs consume “a third of Chrome’s power usage on desktop.” Well, that’s about to change with the latest Chrome update.
Starting with Chrome 57, Google is looking to reduce unnecessary power consumption for background tabs but points out that audio or real-time connections won’t be affected:
Chrome will throttle individual background tabs by limiting the timer fire rate for background tabs using excessive power… Chrome 57 will delay timers to limit average CPU load to 1% of a core if an application uses too much CPU in background. Tabs playing audio or maintaining real-time connections like WebSockets or WebRTC won’t be affected.
According to the search giant, the new throttling mechanism can lead to 25 percent fewer busy background tabs; however, the company’s ultimate goal is to fully suspend these unused tabs and make them rely on new APIs, so you can expect to see future updates bringing even more battery-efficient changes. Chrome 57 has been out for some time now, so make sure to check and see if your laptop’s Chrome browser is up to date!

EVERYTHING WE KNOW ABOUT THE PIXEL 4, THE MOST-LEAKED PHONE EVER

Image
Google’s  Pixel 3 might have been the  most-leaked phone in history . Long before its unveiling, we knew practically everything about it from unboxing videos, photo comparisons, even a full review of the device. Surely, for the Pixel 4, Google would clamp down on leaks to leave some surprises for its debut on  October 15th , right? Let’s just say, if that was the plan, it didn’t exactly work out. We’ve now seen the Pixel 4 XL from every angle and in three different colors. At least seven different sources have touched this phone, many of them confirming the same specs. We not only know which cameras it’ll have, but also what they may be capable of, including air gestures (go figure). That doesn’t even count information Google has already shared  on purpose. So if you want to know almost everything about the Pixel 4 nearly a month before it’s announced, buckle up. We’ve sifted through all of the rumors and information we can find to compile everything we know — and everything we

As 2018 comes to a close, it’s time to look at some our favorite apps of the year. While not all of these are brand new, many of them popped up onto our radar for the first time in 2018, and are definitely worth the attention. Others are some of our favorites that are still best-in-class despite having been around for some time now. We aim to do things differently at TNW, and as such you’re not going to find the recommendations you’re probably used to seeing: Gmail, Skype, Dropbox, and the like. Instead, we want to focus on the best-of-the-best that you may not have heard of, and others that are just special enough to warrant a mention. As always, we’d encourage you to share some of your favorites in the comments below, or on Facebook. Enlight Pixaloop (Free Pixaloop  is one of my favorite apps on the market.
