FAQ
Does the 5UF iOS app use a lot of battery? 
Some users notice that the 5UF app seems to use a large share of battery in the iPhone battery report.
In most cases, this is because once VPN is enabled, iOS counts a large part of network activity under the VPN app. It does not necessarily mean the 5UF app itself is consuming abnormal battery.
A simple way to understand it:
- After VPN is enabled, app traffic goes through the VPN tunnel.
- iOS often attributes part of that network activity to the VPN app in battery statistics.
- So a higher percentage does not automatically mean the app itself is using excessive battery.
Under normal usage, you usually do not need to do anything special.
If the battery drain still feels unusually high, try:
- Updating to the latest 5UF app
- Testing again on another network
- Closing unused background apps
- Restarting the phone and checking again
If the issue remains clearly abnormal, contact support and provide your device model, iOS version, and battery screenshot.
