Let’s start with the physical appearance of both – although they use the same exact screen, OnePlus is just a hair taller and just a little thicker (thanks to extra 100mAh battery) while being a smidgen narrower. The 5T is about 10 grams heavier. R11s has a little different design to it’s fingerprint scanner – it’s not quite round like the 5T’s, it’s a little taller. It’s unknown which material is used on the fingerprint scanner on the R11s but the 5T continues to use ceramic on it’s fingerprint scanner. Oppo thankfully allows some customisation when it comes to devices appearance, as it currently has 3 colours available – black, champagne and red while 5T is only available in black (at least for now). 5T uses USB Type-C connector while Oppo is still using Micro USB.. for some unknown reason..
.. and Oppo is still against using flagship grade processors it seems. The R11s is powered by Qualcomm 660, comes with only 4GB RAM and 64GB internal storage configuration and has Bluetooth 4.2.
The 5T on the other hand uses the latest and greatest Snapdragon 835, alongside 6 or 8GB of RAM and 64GB or 128GB of internal storage and Bluetooth 5.0.
R11s supports micro-SD cards in 1 SIM + 1 micro-SD card or 2 SIM cards configuration. The 5T only allows SIM cards, no micro-SD storage. 5T makes up for that with it’s vast array of 4G LTE bands, Oppo ships with just a few.
OnePlus uses a really light version of their own custom Android software – Oxygen OS. Oppo has taken a totally different approach and uses ColorOS, which is a heavily modified skin of Android.
The price for R11s is about 500 yuan ($75, 65€) cheaper than the base model of 5T.
And what’s the same..
The display’s are identical. Both use the same back cameras (and have the same camera bump) and support Oppo’s VOOC fast-charging (OnePlus has re-branded to Dash Charge). Both transfer files at USB 2.0 speeds. Both have a 3.5mm headphone jack. That’s about it.
