My review is aimed primarily at those who awarded only one star. You should concerns times. that after all the updates from the Samsung battery-Leist Zung distribution has also changed. A real energy guzzlers are the entire Google Apps, especially the Google Play (not to be confused with the play goals). I have almost all Google services (who needs? Already) turned off and what is most important, the time-out of the display must be set to 2 minutes. Tests the times, and you will see your S2 will keep longer without significant charging.
