The HTTP Injector app and VPN does use battery, however, our team have done extensive tests to ensure it's optimized for nearly all common Android smartphones. We assure you that the battery usage of the app is similar to other common consumer apps.
>> The HTTP Injector VPN routes all of the phone's app traffic through the HTTP Injector app.
HTTP Injector processes the data from all of the apps on your phone, since HTTP Injector is processing the data from many apps, Android records the data usage as if it is coming from HTTP Injector app itself. This makes the HTTP Injector app's data usage look very high.
>> Android calculates battery usage partially by how much data an app uses
The more data you use, the more battery you burn. Since the HTTP Injector app looks like it's using a lot of data, Android therefore sees the battery usage as if it's coming from HTTP Injector. This means that data and battery usage from Facebook, Spotify, etc. will then register as coming from the HTTP Injector app in some phones and therefore looks much higher.
