How much battery does Speedify Use?
We often get asked just how much battery Speedify uses. The short answer is that Speedify is very battery efficient. It carefully turns off cellular radios whenever possible in order to minimize your data (and consequently battery) usage.
With every release we conduct a round of tests with streaming video to ensure that the difference in battery usage between running Speedify and not running Speedify is minimal.
If you are concerned about battery life, switching your Cellular connection to "Backup" can help. Doing so will avoid the battery usage associated with speed boosts, while still giving you reliability, failover, and the ability to change geolocation.
But there's one more issue: when Speedify is connected, your phone's Settings app will "blame" Speedify for all Wi-Fi and Cellular usage. Battery usage is literally moved from your apps and attributed to Speedify. You may see Speedify using as much as 20% or 40% of your battery, but this is not accurate: you need to watch the total effect on your battery life.
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.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.

Best for fixed locations. Different network, so outages rarely overlap.
Learn more →Second Starlink
Adds redundancy and throughput for remote sites or heavy usage.

Speedify gives you faster, steadier internet by combining Wi-Fi, cellular, and Starlink
Speedify bonds Wi-Fi, 4G/5G cellular, Ethernet, and Starlink into one connection at the same time, giving you more speed, automatic failover when one drops, and AES-256 encryption on every link.

Always encrypted
Every link runs through an encrypted tunnel, including public Wi-Fi, cellular, and Starlink.
Speedify Feature · Pair & Share
Speedify Pair & Share: share cellular between your devices, both ways
Most hotspots give. Speedify's Pair & Share gives and takes. Two devices running Speedify pair up and each uses the other's cellular connection simultaneously, so you both get faster uploads, faster downloads, and a steadier connection. No extra hardware, no new data plans, no setup beyond a tap.
Learn how Speedify's Pair & Share works ›More speed
Every device you pair with adds its cellular to yours, and yours to theirs.
Stays connected
If a paired device drops out, Speedify keeps you online on the remaining links.
Always private
Every shared connection runs through AES-256 encryption. Your traffic is yours.
No new gear
Runs on devices already running Speedify, over your local network. Pair once, reconnects automatically.
How we test
In the test, the devices were on an 80 Mbps Wi-Fi network. Using either the Xfinity On Demand app or Youtube, they streamed either 30 or 90 minutes of video. The Wi-Fi was fast enough to stream the videos to the devices at the desired resolution.
The networking software was set to one of three modes:
- Without Speedify: The device just used the Wi-Fi network
- Speedify, Cellular Normal: Speedify was running, and, because Cellular was set to Normal, Speedify could use it if it thought the Wi-Fi was getting congested and slowing the video
- Speedify, Cellular Backup: Speedify was running, with the Cellular set to Backup, which means it could only be used if the Wi-Fi appeared to have failed
| Device | Test | Battery Usage Without Speedify | Battery Usage with Speedify, Cellular Normal | Battery Usage with Speedify, Cellular Backup | Speedify Impact, Cellular Normal | Speedify Impact, Cellular Backup |
| iPhone 7 Plus | Xfinity On Demand 30 min | 5% | 6% | 5% | -1% | 0% |
| Galaxy S4 | Youtube 60 min | 23% | 24% | 23% | -1% | 0% |
| iPhone 6 Plus | Youtube 60 min | 16% | 16% | 16% | 0% | 0% |
