Power Consumption of IPv6 vs IPv4 in Smartphone
draft-petrescu-v6ops-ipv6-power-ipv4-00.txt
Abstract
This draft documents preliminary results of measuring the power
consumption of using IPv6 vs using IPv4 on typical applications on a
smartphone. The smartphone is connected on a 4G cellular network
with either an IPv6 connection, or with an IPv4 connection, but not
both simultaneously.
The preliminary results expose a roughly 5% increase in power
consumption on IPv6. More experiments are planned as future work
that may confirm or infirm these figures.

1. Introduction
This document describes preliminary measurement results of power
consumption of IPv6 and IPv4 on a cellular smartphone.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
APN: Access Point Network
3. Power consumption measurements in smartphone
We conducted several power consumption in differents use cases. The
measurement are done with Greenspector probe. We used the smartphone
Huawei mate 8 with an android version 7. In these tests, we used
orange SIM card. The smartphone is able to connect to IPv4, or to
IPv6 Access Point Networks (APNs) simultaneously, or distinctively.
In the smartphone, only the 4G connection is active (not 3G).

The test methodology consist in an automatized test and a probe
provided by Greenspector. First, we specify in the automatized test
which application we want to monitor and for which duration. Then,
we trasfer the test and the probe to the smartphone, launch it and
wait till the end of the test. The probe generates a JSON file where
measures are stored. We take out the JSON files from the smartphone
and send them to Greenspector server in order to be anlyzed.
Finally, different metrics (e.g. battery discharge, process CPU,
network packets, etc.) are shown in a Greenspector webpage (access
available upon request). Some of the measurements are graphically
illustrated in a Digital Object; this object is identified by DOI
10.13140/RG.2.2.13454.77122. This Identifier can be resolved by a
publically available resolver such as dx.doi.org.
All the measurements presented in this draft are preliminary and may
change depending on the details of the measurement conditions.
In order to compare between IPv4 and IPv6 connections in smartphone,
we considered four use cases: video streaming from YouTube, live
video streaming (no cache), web browsing and file download. First,
we run the test, for each of the four use cases, when the smartphone
is using 4G connection and IPv4 APN. Then, we run the same tests
when the smartphone is using 4G connection and IPv6 APN (distinct
connection set up; in each one of these connections only IPv4 is
active, or only IPv6 active).
3.1. Video streaming use case
In this use case, we launch a video of 4m44s using Youtube
application in the smartphone. We associate the Greenspector probe
to Youtube application in order to measure the related power
consumption. The measurement results (a significant selection) are
shown in Table Table 1. As we can see, in same environment and by
moving from the use of IPv4 to IPv6, the battery discharge is
increased by around 5%.
+------------------------+-------------------+
| IP version | Battery discharge |
+------------------------+-------------------+
| IPv4 | 57.61 mAh |
| IPv6 | 60.90 mAh |
+------------------------+-------------------+

3.2. Live video streaming use case
In this use case, we launch a live video during 5 minutes using
Youtube application. For this use case, we considered the live
streaming provided by a webcam in Amesterdam. This webcam can be
reached either using IPv4 or IPv6 connection
(https://www.youtube.com/watch?v=Y5N-OM9RT8o). It was setup in order
to demonstrate that it is possible to use IPv6 exclusively in the
production and delivery of a live video stream
(https://www.terena.org/webcam/). We associate the Greenspector
probe to Youtube application in order to measure the related power
consumption. The measurement results are shown in Table 2. We note
that, in IPv6 network, the streaming of a live video in smartphone
consumes approximately 3% more than IPv4 network.
+------------------------+-------------------+
| IP version | Battery discharge |
+------------------------+-------------------+
| IPv4 | 66.11 mAh |
| IPv6 | 67.89 mAh |
+------------------------+-------------------+
Table 2: Power consumption in live video streaming use case
3.3. Web browsing use case
In this use case, we launch Chrome application with the URL that can
be browsed using both of IPv4 and IPv6 connections (e.g.
http://www.kame.net). We associate the Greenspector probe to Chrome
application in order to measure the related power consumption. The
measurement results are shown in Table 3. We note that browsing
using IPv6 networks discharges the battery approximately 12% more
than browsing using IPv4 networks.
+------------------------+-------------------+
| IP version | Battery discharge |
+------------------------+-------------------+
| IPv4 | 3.31 mAh |
| IPv6 | 3.73 mAh |
+------------------------+-------------------+

3.4. File download use case
In this use case,we use the "andFTP" application to download a file
of 7MBytes. The "andFTP" is an android application dedicated for
file transfer. We associate the Greenspector probe to the andFTP

application in order to measure the related power consumption. The
measurement results are shown in Table 4. We note that downloading a
file using IPv6 network discharge the battery approximately 36% more
than using IPv4 network.
+------------------------+--------------------+
| IP version | Platform discharge |
+------------------------+--------------------+
| IPv4 | 69.21 mAh |
| IPv6 | 94.15 mAh |
+------------------------+--------------------+

4. Future Work
In the next revisions of this draft, the following topics will have
to be addressed:
o Measure consumption of HTTP2 protocol, compare IPv4 and IPv6. An
earlier measurement of HTTP2 is available at
https://greenspector.com/articles/article-http2-latency-and-
energy.html
o Use other smartphone brand and OS version.
o Analyse the wireshark traces to understand whether or not the
right parameters are used for IPv6.
o Use an alias in order to make sure be on same POP, and then try
with different POPs.
o Perform measurements and compare power consumption of WiFi IPv4 vs
WiFi IPv6.
5. Security Considerations
There is a need to explore how much more power consumption (if any)
is generated by https vs http, with IPv4 and IPv6.
6. IANA Considerations
IANA?
