What is the maximum download speed for iPhone 11?

The iPhone 11 is capable of fast download speeds thanks to its compatibility with Wi-Fi 6 and Gigabit-class LTE. Here is a breakdown of the maximum download speeds:

What is the maximum download speed for iPhone 11?

Wi-Fi Download Speed

  • Supported Wi-Fi standards: 802.11ax Wi-Fi 6
  • Theoretical maximum speed: 1.2 Gbps
  • Practical speeds: 300-500 Mbps over Wi-Fi 6 connection

The iPhone 11 has a Wi-Fi 6 compatible modem that supports the newest Wi-Fi standard. This allows for faster theoretical download speeds of up to 1.2 Gbps compared to 866 Mbps on Wi-Fi 5.

However, real-world speeds will be lower and depend on your internet connection and Wi-Fi router capability. Over a Wi-Fi 6 router, practical download speeds of 300-500 Mbps can be achieved.

Cellular LTE Download Speed

  • Supported cellular networks: Gigabit LTE
  • Theoretical maximum speed: 1 Gbps
  • Typical speeds: 300-600 Mbps

The cellular modem in the iPhone 11 supports Gigabit LTE for fast download speeds up to 1 Gbps theoretically. Real-world cellular speeds depend on coverage and will be lower.

Under good LTE coverage, download speeds of 300-600 Mbps can be reached on the iPhone 11. This allows for quick downloads and streaming media. Peak speeds require optimal signal conditions.

So in summary, the iPhone 11 can deliver incredibly quick downloads with support for bleeding-edge Wi-Fi and cellular data standards. Actual speeds will vary below the 1 Gbps maximum, with 300-600 Mbps being typical ranges.

Key Takeaway: The iPhone 11 supports Wi-Fi 6 and Gigabit LTE for theoretical peak download speeds up to 1.2 Gbps over Wi-Fi and 1 Gbps over cellular. Real-world download speeds range from 300-600 Mbps on average.


With capabilities like Wi-Fi 6 and Gigabit-class LTE, the iPhone 11 is ready for the future of high-speed connectivity. Download speeds can surpass those of previous iPhones by leaps and bounds, enabling faster browsing, streaming, and usage on the go.

While theoretical maximums are over 1 Gbps, actual user experience will typically see 300-600 Mbps for downloads under good conditions. Overall, the iPhone 11 sets a new standard for LTE smartphones and brings a taste of next-generation network speeds to your hands today.

Frequently Asked Questions

  1. What internet speed does an iPhone 11 need?
    An iPhone 11 can take advantage of fast internet connections but only requires a minimum of 30 Mbps internet speeds for good performance. Faster speeds exceeding 300 Mbps are preferred for the best experience. 
  2. How can I test iPhone 11 download speed?
    You can test iPhone 11 download speeds using Speedtest apps and fast.com to measure current Wi-Fi and cellular data speeds. Make sure you are connected to 5Ghz Wi-Fi or LTE for optimal speeds. 
  3. What affects iPhone 11 internet speed?
    The main factors are Wi-Fi network congestion and quality, distance from router, cellular coverage and signal strength, location, and concurrent usage or downloads. Internet provider speeds also play a role. 
  4. Does iPhone 11 support 5G networks?
    No, the iPhone 11 does not have a 5G modem. 5G connectivity is only available on the iPhone 12 series and newer models like iPhone 14. The iPhone 11 is still very fast for an LTE phone. 
  5. How can I improve my iPhone 11’s download speed?
    Making sure you have excellent Wi-Fi coverage and LTE signal can improve speeds significantly. Reducing interference, upgrading internet plans, restarting your iPhone, and closing background apps may also help. 
  6. Will iPhone 11 download speed improve in iOS updates?
    Apple does implement some modem optimizations and performance improvements in iOS updates for iPhone 11. However, hardware capabilities remain the same, Wi-Fi 6 and Gigabit LTE highest speeds. 
  7. Does low storage affect iPhone 11 speed?
    Yes, having very low storage remaining can degrade iPhone performance and download speeds. It’s recommended to keep over 10GB storage free for good performance. 
  8. What Wi-Fi routers work best for iPhone 11?
    We recommend Wi-Fi 6 routers like Linksys Atlas Max 6E or NETGEAR Nighthawk AXE11000 for maximum iPhone 11 Wi-Fi speeds and performance. An affordable Wi-Fi 5 router will still deliver good speeds. 
  9. How do I check what cellular network my iPhone 11 is connected to?
    Go to Settings > Cellular > Cellular Data Network on your iPhone 11 to identify the specific cellular network you’re connected to and obtain info like signal strength. 
  10. Can I further boost iPhone 11 signal and speeds?
    Adding an affordable signal booster like the we Boost Home Studio can amplify cellular and Wi-Fi signals to deliver faster speeds if coverage is currently poor inside your home or office. 
  11. Why is my iPhone 11 LTE speed slow?
    If your iPhone 11 has slow LTE speeds, the issues could be weak cellular coverage/signal, network congestion, outdated carrier settings, interference, or using older SIM card. Try moving location or network troubleshooting steps. 
  12. Is there a way to prioritize downloads on iPhone?
    Yes, you can pause other downloads or temporarily disable Wi-Fi/cellular data for other apps to prioritize and speed up downloads in your main app on an iPhone.
