best phones for dexcom G6

 Check Price on Amazon

Apple’s iPhone 13 Pro Max plants its flag at the summit of smartphones. It hits a lot of the marks you’d want for a premium smartphone. The Apple iPhone 13 Pro Max is our Editors’ Choice for the best phone for Dexcom G6.

The iPhone 13 Pro Max is one of the first phones powered by Apple’s A15 Bionic chip, which is complemented by 6GB of RAM. Meanwhile, storage options include 128GB, 256GB, 512GB, and, yes, 1TB.

It’s the cameras where the iPhone 13 Pro Max stands out the most against most phones on our list. The iPhone 13 Pro Max has four cameras, including a 12MP (wide)/13MP (telephoto)/5MP (ultrawide) triple array on the back and a 12MP selfie sensor on front.

It’s worth adding, too, that the 13 Pro Max boasts a 120Hz ProMotion display. This makes browsing the internet a smoother experience than typical 60Hz displays, not to mention much smoother gameplay when playing games that support higher frames-per-second rates.

Just as importantly, build quality is reassuringly good. This is a phone that serves up power, speed and other impressive performance chops in a gorgeous chassis.

The iPhone 13 Pro Max handles many tasks like a champ, as well. Using the Dexcom G6 app on the 13 Pro Max is a pure joy.

As for audio, you’d be equally impressed. The iPhone 13 Pro Max’s audio is respectable.

How about the Touch ID? Well, there isn’t one really.

Elsewhere, it features a remarkable battery life and debatably the best you’d find on a smartphone. If you’re looking for a phone that can last all day, this is it.

The iPhone 13 Pro Max is a huge phone and an expensive one, so it won’t appeal to many — but if money is no object, and you want the best phone for Dexcom G6, the Apple iPhone 13 Pro Max is the way to go right now.

2. Samsung Galaxy S21 Ultra 

best phones for dexcom G6

Check Price on Amazon

Right now, our absolute favourite Android phone is the Samsung Galaxy S21 Ultra, which is the best Android phone for monitoring your glucose level using the Dexcom G6 app.  

A big part of the Galaxy S21 Ultra’s appeal is its display. It delivers a stunning picture quality with its 120Hz refresh rate. The screen is very bright, too. You won’t have problems viewing maps, images and videos, outdoors in real time.

Its build quality is reassuringly good.

The S21 Ultra is super fast thanks to Qualcomm’s Snapdragon 888 chipset tucked inside it. With the impressive chipset and 12GB or 16GB of RAM tucked inside the Galaxy S21 Ultra, the smartphone truly delivers.

Weighing in at 0.50 pound (227g), the S21 Ultra isn’t the lightest smartphone in its class. 

Meanwhile, the phone comes in two major colours: Phantom Black and the attention-seeking Phantom Silver. There are other colours, nonetheless, including Phantom Brown, Phantom Titanium and Phantom Navy.

Another feature worth highlighting is the phone’s cameras. They are outstanding. The rear holds a 108MP (wide) main camera, 12MP (ultra wide) camera, 10MP (telephoto) lens with 3x zoom technology, and another 10MP telephoto lens, this time with a 10x zoom unlike the Apple iPhone 12 Pro Max which manages 2.5x optical zoom. The S21 Ultra’s 40MP selfie camera is excellent as well.

If you want plenty of storage, the Samsung S21 Ultra is a good choice. Samsung has made available three storage variants on the S21 Ultra: 128GB, 256GB, or 512GB. The base model ships with 12GB of RAM. Need more RAM? Well, there is a 16GB RAM variant which costs even more.

The S21 Ultra isn’t without faults (what phone is?). However, the downsides are few and far between. You won’t find a microSD card slot. Also missing on the Galaxy S21 Ultra is a charger in the box — you won’t find this on most smartphones like the Xiaomi Mi 11 and iPhone 12 Pro right now.

With the 5000 mAh battery tucked inside the S21 Ultra, you may likely get an all-day battery performance, however, this depends on usage. Other smartphones like the Asus ROG Phone 5 have moved past the 24-hour battery life and are racing towards a 3-day mark.

Given its solid specs and impressive performance chops, the Samsung S21 Ultra remains the best Android phone for Dexcom G6.

PROS

  • Impressive AMOLED display
  • Super fast performance
  • 120Hz refresh rate
  • Fantastic pen integration
  • Very good cameras
  • Excellent battery life

CONS

  • Expensive
  • No microSD card slot

5. Apple iPhone XR

best phones for dexcom G6

Check Price on Amazon

As you would expect, the Apple iPhone XR is run by the powerful A12 Bionic chipset and iOS 12. Apple’s A12 Bionic chip puts to shame the Snapdragon 855 and 845 chipsets tucked inside some phones. The iPhone XR is super-fast, with a better speed.

The operating system, iOS 12, on the smartphone is upgradable to iOS 13.1.2

Blue, White, Black, Yellow, Coral, Red are the colour variants you would see.

Apple has made available 64GB, 128GB, and 256 GB versions of the smartphone and all of them come with 3GB of RAM. The storage options are OK, but the RAM size which isn’t bad for a phone falls short of what other good phones manage.

You won’t find the 3D Touch technology on the XR as Apple has removed his feature from the phone. Also missing from the iPhone XR is the trademark physical home button.

Depending on usage and settings, you may likely get an all-day battery performance from the iPhone XR which has a paltry 2942 mAh battery tucked inside it.

Overall, the Apple iPhone XR remains a decent phone for Dexcom G6 app.

PROS

  • Excellent camera
  • Impressive audio
  • Ample colour variants
  • Decent battery life
  • Price is fair for an iPhone

CONS

  • Screen resolution could be improved
  • No 2x optical zoom technology on camera

6. Samsung Galaxy S10 Plus

best phones for dexcom G6

Check Price on Amazon

Packed with one of the best processors on the market, the Qualcomm Snapdragon 855, using the Dexcom G6 app on the S10 Plus is seamless as you will not have issues with speed because the phone is amazingly fast. No wonder Samsung nicknamed it the Performance Edition.

Two storage options enough to store your all images, videos, and other media are available: 1TB storage with 12GB RAM and 512GB storage with 8GB.

You need not be too anxious about the battery performance of the S10 Plus while using the Dexcom G6 app as the S10 Plus has a 4100 mAh battery lasts almost 13 hours per charge.

If you’re using the Snapdragon model, you would enjoy a slightly longer battery life than someone who owns the Exynos model. However, for both models, battery life reduces after prolonged use. Adjusting the display brightness to minimum saves battery life.

The Samsung Galaxy S10 Plus is one of the best phones for Dexcom G6.

PROS

  • Excellent dual rear cameras
  • Excellent display
  • Sleek design
  • Very good battery life
  • Expandable storage

CONS

  • Fingerprint reader could still be improved

Check Price on Amazon

The Google Pixel 4 is a fast and durable phone compatible with the Dexcom G6 app. It is especially for those on a strict and limited budget, but still want a certain level of performance.

Its internals are nothing to scoff at – Snapdragon 855 processor, 6GB of RAM and 64GB or 128GB of storage. 

The display looks fine, but is nothing mind-blowing.

It offers excellent performance at a price point that’s a lot more affordable.

Elsewhere, the Pixel 4 comes with a 12.2-megapixel wide-angle sensor, as well as a 16-megapixel telephoto lens. 

Face Unlock using 3D face recognition technology, Motion Sense which tracks motions around the Pixel 4, excellent Google Assistance integration are features worth highlighting.

The Pixel 4’s 2800 mAh battery will last up to 14 hours on a single charge depending on usage.

Truth be told, the Pixel 4 might not be the prettiest or most powerful phone out there, but for anyone looking for a phone that won’t gobble up their entire stimulus check, this is an excellent combo of power and affordability that’s hard to pass up.

Apple remains the industry leader when it comes to manufacturing responsive and superfast smartphones capable of running many demanding applications.

Like the iPhone XR, the iPhone XS Max which has good processors – the A12 Bionic chip – tucked inside, is one of such smartphones designed not just for regular phone users, but has good internals for using the Dexcom G6 app without issues.

The phone is armed with a massive and colorful 6.4-inch OLED display and has a battery life better than some of the best smartphones on the market.

Opening apps on the XS Max takes less than 60 seconds. Using the DJI Fly app on the XS Max is a breeze. This is what you get when you buy on a smartphone with the good chipset.

Elsewhere, there are three storage options: 64GB, 256GB, or 512GB.

Given its impressive internals, we recommend the iPhone XS Max as one of the best phones for Dexcom G6.

The Google Pixel pairs the Qualcomm Snapdragon 845, Android 9 Pie, 64GB or 128GB of storage and 4GB of RAM. These specs are perfect for using the running the Dexcom G6 app without a hitch.

You may feel disappointed that the Pixel 3 manages only 4GB of RAM without more options. We feel the same way, too. That being said, the 4GB of RAM tucked inside the Google Pixel 3 can handle all the processing needs of the smartphone.

The Google Pixel 3 has the right size (5.5 inches) and weighs 0.15kg (0.33 pounds).

The Pixel 3’s paltry 2915 mAh battery isn’t the best you’ll find on a smartphone.

All in all, the Google Pixel 3 remains an excellent budget smartphone and one of the best phones for Dexcom G6.
