What tech products or categories are you most passionate about?

Everything that remotely falls under the umbrella of technology gets me excited, but I've been directing my attention more towards the day-to-day computing devices like laptops, desktops, and smartphones that are shaping the future.

How long have you been interested in technology?

I may have started covering the technology space "officially" in 2016, but I've been obsessed with technology and gadgets for as long as I can remember. I was lucky enough to get my hands on a Motorola Razr V3 in 2006, shortly after which I started writing about technology on my blog.

What was your first computer?

I've been dabbling with computing devices for as long as I can remember, but it wasn't until 2010 that I built my first computer. It coincided with the launch of Intel's 2010 Core processor family, and I vividly remember how excited I was to finish the build and install a copy of GTA IV. The good old days when choosing the right component or finding a stable game to run wasn't a chore.

Simple steps to improve the battery life of your Android phone

Here are a few simple tips and tricks to improve the battery life of your Android phone so that you don't have to charge it as often.

One of the most common problems users have with their phones is sub-par battery life. The battery units inside our phones have gotten bigger over the years, but power consumption has also significantly increased due to newer components. For instance, the displays have become brighter with high refresh rates, and more devices now support 5G connectivity. All of these along with some similar factors chip away at your phone's battery, and you're left hunting for a charger just a few hours into your day. A 4500mAh battery may seem like a lot, but you're more than likely to drain it within a day, especially if you are a heavy user. If you're unhappy with the battery life of your Android phone, then here are some ways in which you can improve it:

The OnePlus 10 Pro and OnePlus 10T may not best smartphones out there right now, but they both tick a lot of the right boxes to stand as reliable alternatives to $1,000 flagships. The OnePlus 10 Pro arrived earlier this year with some meaningful upgrades over the OnePlus 9 Pro, while the OnePlus 10T recently entered the market as a solid mid-year refresh with a sharp focus on performance.

If you're wondering which pair of earbuds to buy for your day-to-day usage, or whether you should upgrade from your regular Buds 2, you've come to the right place.

The Google Pixel 7 Pro is truly one of the best Android phones to buy in 2022 due in large part to its slightly lower price compared to the competition. It certainly has the edge over a lot of flagships handsets when it comes to value, and it's still a top-tier flagship and Google's best.

The Pixel Watch is Google's first smartwatch, and it's a pretty compelling offering for a "first-gen" product. We wouldn't say it's the best smartwatch on the market right now, but there is a lot to like about it. The Pixel Watch turned out to be a lot better than what we expected, so we see why many people, including the ones that use an iPhone, may find it very appealing. It works well with Android phones, but what about an iPhone? Can you use the Google Pixel Watch with an iPhone? The short answer to that question is no, the Pixel Watch is designed only to be used with Android phones.

I used many Samsung phones this year, but the one I love the most is the smallest Galaxy S22 model. I was full of praise for this phone in my Galaxy S22 review, and I stand by it even months later. It matches its siblings in many categories but is far more comfortable to use thanks to its small form factor. I've recommended this phone to a lot of people in the past, but here's another reminder to check out the Galaxy S22, especially since you can get over $200 off right now.

Razer's best webcam is now available to purchase with a huge discount for Cyber Monday. You can get your hands on a brand-new Kiyo Pro webcam for as little as $88. It's pretty close to the lowest price we've seen for this webcam, so it's definitely worth considering right now. This is easily one of the best webcams you can buy in 2022, and it handily beats a lot of other options out there.

Cyber Monday is here, which means fresh discounts are now popping up to save you money in case you missed all the deals so far. This last set of deals will essentially round off the end-of-year deals season, so it's your best chance to save big on gadgets and accessories. We've already covered plenty of PC and laptop deals, but we wanted to highlight the best mechanical keyboards in a separate post mainly because of the sheer number of options that are available at a discounted price right now. So if you are looking to pick up a new gaming keyboard for the holidays, then here are the ones that are worth considering:

The Xbox Series S dropped to $250 a few days back, and we thought it would be the best holiday deal this year. But little did we know that Amazon was cooking something better for Cyber Monday. That's right, you can get your hands on a brand-new Xbox Series S Holiday console for as low as $200 from Amazon. This appears to be a limited-time deal, so we suggest you grab it as soon as you can to get a head start on Cyber Monday shopping. Microsoft's cheapest next-generation console is listed for just $240 on Amazon right now, which is already more affordable than its Black Friday deal price. However, you can save an additional $40 with the coupon code "XBOX" during checkout and get the equivalent amount as Amazon Credits.

If you were waiting for Black Friday or Cyber Monday to buy a new TV for your entertainment setup, then we may have found the best one to seal the deal for you. The LG C2 OLED is one of the best smart TVs you can buy in the US right now, and it's currently down to a starting price of just $900. This is the lowest price we've seen for this particular TV, and it's easily the Cyber Monday TV deal to beat right now.

The Bose SoundLink Revolve speakers have been a dominant force among Bluetooth speakers, and they rarely get big discounts. But the relatively new SoundLink Revolve+ 2 portable speaker is now available for a great price on both Best Buy and Amazon. In what we think is going to be a limited-time deal, the new SoundLink Revolve+ 2 can be had for just $230. That's a $100 discount because it usually retails for $330. Both the silver and black variants of the speaker are available at a discounted price, and you can grab them by following the link that's mentioned in the box above.

You can buy the Sony WF-1000XM4 ANC earbuds for just $178 right now as a part of Best Buy's Black Friday sale. This is the lowest price we've seen for these earbuds as they usually go for around $280. It comes in both black and silver colors, and they're both readily available in stock at the time of writing this article.

You may have seen a lot of smartwatch deals over the last few days, but I think none of them will come close to the value you'll find on this deal for the Amazfit GTR 4. I reviewed this watch a couple of months back and said it was a no-brainer at $200. But right now you can pick one up at a $40 discount, which makes the already super-cheap watch an absolute steal. That's right, the Amazfit GTR 4 is currently available for just $160 as a part of Amazon's Cyber Monday deals. It's available in two finishes, and they're both in stock at the time of writing this article.
