1. Go to Netflix.com.
2. Click Sign In to Get to Your Account.
3. Sign In on the Login page. Input your account’s email address and password here.
4. Choose a Profile. If you have multiple profiles, you’ll want to choose the option for which you want to change the data-usage settings. If you want to change all the profiles, follow the steps outlined here for each additional profile.
5. Click Your Name and Choose Your Account. Once you’re on your Admin account, you’ll be brought to your Netflix home page. Now click your profile name at the top-right of the screen. From the drop-down box, choose Your Account, so you can get into the settings for your profile.
6. Scroll Down and Choose Playback Settings. Toward the bottom of the page, under the My Profile header, you’ll find an option for “Playback settings.” Click that to make your choice.
7. Choose Your Desired Playback Quality. By default, Netflix sets the playback quality to Auto, allowing you to get the best visual experience based on your network’s capabilities and default settings in the app.
Aside from Auto, Netflix gives you three data usage options based on your desired usage.
Low (Basic video quality, up to 0.3 GB per hour of usage)
Medium (Standard video quality, up to 0.7 GB per hour of usage)
High (Best video quality, up to 3 GB per hour for HD, 7 GB per hour of Ultra HD)
Now’s the time to check your data usage, see how much data you actually want to consume, and pick your option. The setting will be applied to your account and will determine the quality of your content.
The lower the option you choose, the worse the video quality.
You might also want to consider whether to keep the Auto-Play option toggled. By default, it’s set to on. If you’re worried about data usage, toggle off that option.
8. Click Save. Now that you’ve chosen your video-quality option, click save. Your video quality and data usage will now be governed by that setting.
