New Apple Modem with C1 Chip Prolongs Battery Life for iPhones. Get More Reliable Internet by Joining 4G / 5G from the C1 Modem with Wi-Fi Using Speedify.
On February 19th, 2025, Apple announced its first custom cellular modem - the C1 - which will make its debut in the new iPhone 16e. According to them, the C1 is the first modem designed by Apple and the most power-efficient modem ever on an iPhone, delivering fast and reliable 5G cellular connectivity.
The main selling point for the new C1 5G modem from Apple is its power efficiency. It's a proven fact that your battery drains faster when you're using your 4G / 5G cellular modem to access the Internet. That's why we're looking forward to test the new iPhone 16e and the following iterations which will include the new C1 Apple modem.
One thing is certain: this means that you'll be able to surf the Internet for longer till your next battery charge. You'll also be able to get faster and more reliable Internet by using both the 4G / 5G connection from the new C1 Apple modem and a Wi-Fi connection together with Speedify.
Quick answer
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.

Why Join 4G / 5G Cellular Internet with a Wi-Fi Connection?
The new Apple C1 modem sounds great, but in essence it's a streamlined cellular modem. It depends on the coverage and signal strength of the network operators. Whenever the coverage is poor or the signal strength is subpar, the Internet connection will start lagging, videos will start buffering, live streams will drop out, and so on.
That's why it's essential you use both Internet sources on your iPhone - 4G / 5G mobile data AND Wi-Fi, where available, at the same time. You can only do that with the Speedify app - the only VPN that combines Wi-Fi, 4G, 5G on your iPhone to keep you online and secure when it matters most.
Speedify Allows You to Connect to Multiple Hotspots at the Same Time Using the New C1 Apple Modem
Speedify's Pair & Share feature makes sharing 4G / 5G cellular data between multiple devices very easy to do: you just have to use the app and be on the same network with the devices that share their Internet connection. All of them will benefit from the enhanced speed and reliability. And those iPhones that have the C1 Apple modem will also benefit from the power efficiency Apple claims to deliver.
Speedify intelligently distributes traffic across your hotspot connections, ensuring optimal performance without any manual intervention. When one connection weakens, it seamlessly transitions to stronger ones. This applies to all devices and users connected, so everybody gets better Internet.
All your connections are encrypted, protecting your data across multiple hotspots. This is especially important when using public Wi-Fi or hotspots in unsecured locations.
