Scenario:Using the Android phone/tablet on "TO GO" where there is no Wi-Fi, and use to access Internet over the mobile network data to access your 'traveling apps': news, weather, maps, etc.
Solution:Here are few tricks to play with in the Phone Settings:
1. Disable the Wi-Fi (set it on OFF in the Settings screen).
Note: you can enable it when you are on more statically location, and where you can charge the phone (work, office, friends places, etc.)
2. Disable Apps Notifications: Always, when you install a new application go to its "settings / configuration" screen and turn off all "automatic data pulling or pushing" or "notifications".
Here is an example of the "Yahoo Weather" notification app internal setting, which I disable:
I already have the Weather widget on the screen, so I don't need to see the temperature in the notification bar.
3. Disable Global Notifications: In the "Manage applications" section, disable the "Show notifications" check-box for all applications that you want to keep 'silent'.
Here is an example screenshot:
4. Disable App Data Usage: In the "Settings > Data Usage" you can see all the apps that are going over mobile network.
Select each application from that list (in above example: Flipboard) and go to its "app data usage" screen. At the very bottom of this screen (sometimes is not visible, so you have to scroll-down a little) there is the setting "Restrict background data", which is unchecked. You have to check it.
- from all my apps, I let only the "Yahoo Weather" application to work on background, all other (inclusive the Google Play Service) are not allowed to do this, and from 2 hours battery life I got 2 days.
- Disable Data Usage setting works only when you are using the 'mobile internet', not over the Wi-Fi. This means that over Wi-Fi all apps can work in background without any settings change. Usually, when we are on Wi-Fi connection, we are located in a place where we can easily charge the phone (work, home, etc.), so there is no problem if all apps are working in background.
Thank you for reading this article, and I hope it will help you to squeeze more juice out of your battery.

Another quick trick:
5. Use the full battery cycles as much as possible:
- charging from 0 -->100% in one go
- usage from 100% --> 0% in one go
no short charging steps in the middle (i.e. from 80 --> 100, 0 --> 40 etc.).
