Sometimes it just keeps its' <STRONG>"Data Dormacy" wake lock</STRONG> on for very long periods of time, preventing the phone from entering the "<STRONG>Deep Sleep</STRONG>" mode (where battery consumption is the smallest). This in turn, causes the phone to drain all battery in less than one day, while usually I am able to keep the phone running for about 48h.</P><P>I hoped that this issue would be fixed in subsequent updates, but it apparently is not.</P><P>Regarding the applications I use - I do not believe they caused this, as I have disabled the G+, facebook, and others. Only thing that is synchronizing is my e-mail. Besides - the phone usually works well for a week or so, and then suddenly this bug appears, eating some 30% of battery overnight for example.</P><P>This issue pretty common, at least between users from Poland.</P><P>If your developers need any more details about this issue, I would be happy to provide them (I am programmer myself - I can handle really difficult stuff).</P><P>Best regards</P> Mon, 03 Feb 2014 12:46:34 GMT Devastator 2014-02-03T12:46:34Z https://community.sony.com.mk/t5/xperia-archive/sony-xperia-l-battery-drain-issue-with-some-research-done/m-p/3169150#M338184 <P>Hello,</P><P>In general I am quite satisfied with the Xperia L smartphone, but it has one annoying issue, that existed in the 0.26 software, and is still present on the 1.14 - the<STRONG> battery drain issue</STRONG>.</P><P>I have tried to track down this issue, and the responsible application is "<STRONG>Phone</STRONG>".
