Your smartphone is the one piece of tech that you carry on your person nearly every hour of every day, so you should really love the phone you're carrying. To ensure that you get the best smartphone for your needs and budget, we've broken it down by the specifications that you'll see listed on carrier and company websites.
Processor and RAM
The processor and RAM are the two most important parts of any phone. They determine how smoothly it runs and works through intense tasks like gaming or multitasking.
Storage is also incredibly important because the amount of storage you have determines how many photos, songs, videos, and apps you can have downloaded on your phone. Never buy a 16GB phone — you will run out of space and regret it. 32GB is okay for most people, but if you take a lot of photos, have tons of songs or videos downloaded, or you're an app junkie, you will want 64GB, 128GB, or 256GB of storage. Unfortunately, adding storage costs money.
Phones come in several sizes now, though most are growing ever bigger. Your average smartphone has at least a 5-inch screen, and many have nearly 6-inch screens. Luckily, bezels are slimming down, so now, having a phone with a 5.8-inch screen like the iPhone X means you're holding a small-sized phone that's easy to grasp and operate one-handed.
Most smartphones can last through a busy day and a half, but some can endure two days of heavy use. Others, like the smaller iPhone 8, may only last heavy users a day before they need a charge.
Ports (or lack thereof)
Ever since Apple axed the 3.5mm headphone jack on the iPhone 7 and 7 Plus, phone makers have been getting rid of the jack, too. That means you can't plug your headphones in unless you use an adapter or special earbuds. If you end up with a phone that lacks the jack, we recommend you get a nice pair of wireless headphones and live happily ever after.
Apple provides updates to its iPhones for about four years after their release, so theoretically, you can have your iPhone safe and up to date for four years before you should buy a new one. Always update your software to get important security patches and new features. You may experience slowdown on older devices, but iPhones typically hold up well.
Android phones are something else entirely. Unless you have a Google Pixel phone, you won't get software updates all that quickly. Google also ceases updates after a time, but security patches continue longer.
Consider your purchase an investment. Your smartphone is more than a communication device — It is your camera, your computer, your photo album, your record player, and your gaming console, too. A good smartphone can last you for years, but a cheap one with poor specs will be outdated more quickly, and you'll end up spending more in the long run. That $1,000 price tag on the iPhone X looks less scary when you consider that it could last you for four years.
How to buy
You can get a smartphone from your carrier by paying full price or paying in monthly installments. You can also buy one at stores like Target, Best Buy, Amazon, or directly from the phone maker. We recommend you buy it unlocked so you can switch carriers any time you choose, but we understand that carrier deals are often too good to give up.
For iPhone fans, the Apple iPhone Upgrade Program lets you get a new iPhone every year so long as you've made 12 monthly payments on your current phone. It's basically like renting your smartphone so you can upgrade all the time. Some carriers, like T-Mobile, offer a similar program. — Malarie Gokey
