These phones will be a catalyst for your business.
The OnePlus 6 is the newest phone and like its predecessor, it is an economical flagship handset, and delivers one of the best Android phone experiences on the market, particularly when using it for work. You have the choice of either 6GB or 8GB of RAM based on your needs. For most folks, 6GB will be more than enough.
The battery life could be better, so be sure you have quick access to a charger if your work depends on you always being connected, and there's still no microSD support on the OnePlus 6, much like previous OnePlus phones, but you do have the option of either 64GB or 128GB of internal storage.
The true highlight of the OnePlus 6 is the price, though, and this might be one of the best devices for you on this list if you're seeking to spend as little as possible on a top-of-the-range phone for your business needs.
If you're wanting the best Apple business smartphone, then the iPhone XS is the one you want. It's the pinnacle of Apple's smartphone design, having a gorgeous 5.8-inch OLED screen, improved battery life and an incredible camera that's arguably the best you'll have on a smartphone. It's quite expensive though, but if you want a business smartphone that can do practically everything, and with a stylish design, then this is the one to buy.
Samsung Galaxy Note 8
Samsung has created another amazing productivity-focused device with the Samsung Galaxy Note 8, making it one of the best smartphones for business. Thanks to the huge Infinity Display you get loads of screen space to work on, without the body being bulky to carry around, and the S Pen stylus is something not a lot of other phones provide, and the all-around speed is almost unbelievable at times. It's really worth looking at if you want a brilliant business smartphone, particularly now that its price has dropped.
