Many variables come
into play when you consider battery life on a device. Based on the results of
analysis and testing on a variety of devices at Citrix, it is possible to set
some expectations, however, for when you deploy XenMobile and the resulting
effect on battery life.
- Because all devices and batteries
differ, the information stated in this topic is expressed in terms of
percentages, not actual hours or minutes.
- In all cases, unless noted, Bluetooth,
location services, and WiFi were set to
Off during testing; auto brightness was enabled, and
only a single email client was used at one time (for example, WorxMail and not the native Android or iOS email client).
As a result of the tests, the overhead to battery life when you
use Worx Home, WorxMail, and Receiver is approximately 15 percent. If an
organization has a particularly high-security deployment, with many packages and
policies configured for apps and devices, and if users may not have the
knowledge of how to minimize or disable the services and processes running on
their devices manually, the overhead to a battery could
reach 25 percent. If users experience a reduction in battery life of greater
than 30 percent, you should check the
on the user device.
Note: In the release of the Worx apps in XenMobile 8.6.1, as shown in the following figure, battery drain has improved by approximately 15% in tests that simulate active WorxMail use for 24 hours on an iPhone 5 running iOS 7.04. In the test, the connection occurred for 9 hours over 4G and 15 hours over WiFi.

The tests and
analysis revealed the following results with regard to particular WorxMail
configurations prior to the 8.6.1 Version, and connections to the Device Manager server or Apple:
Improving Battery Life
The following list
of tips can help extend the battery life of user devices when you deploy
- If you’re using WorxMail, disable your
native mail client and other unnecessary account synchronization policies.
- Disable services like Bluetooth, WiFi,
and location services.
- When you are roaming or out of a solid
service area with a good connection, disable your mobile network (3G, LTE, and
- Use the latest versions of WorxMail
for Android and iOS.
- Keep your Android and iOS firmware
- Reduce the brightness of the device to
a lower level and keep auto-brightness on.
- Keep auto-lock enabled and set it to a
low value like 1 minute.
- Turn off notifications for apps that
you don’t use.
