to Uninstall at the top of the screen. Home screen widgets use some power to update them-
selves, so don't place widgets that you don't use.
Keep Apps Up to Date
Developers often improve apps to reduce battery use, so keep them up to date. Some apps
update automatically, while others require your permission. Check the Notification area at
the upper left corner of the screen for apps that are waiting for permission. If you have an
LTE tablet or a phone, you can also let apps update only via Wi-Fi, which uses less power
than LTE (and avoids using your data allowance.)
Reduce App Polling
Some apps, such as Facebook, periodically check for updates. Not all apps allow you to
set the interval but for those that do, increasing the update interval uses less battery power.
Some news and RSS feed apps also let you change the update frequency.
Turn off Flash Video
Flash video uses a lot of power, which is apparently why Adobe has discontinued Flash
support for mobile devices. So don't install Flash unless you need it- and if you do use
it, set your Flash-compatible browser to only load Flash when it needs it. For example, in
Puffin browser ( http://bit.ly/1cy3mTZ ), tap the Menu icon at the upper left corner, scroll
down and tap Settings, then check that Load Flash is set to Auto.
Resetting your Device
If battery drain still seems excessive, you can try resetting the device. This shuts down un-
necessary apps. See Resetting your Device .
