Hello, I have found the following strange behaviour:
My personal smartphone is a Blackberry Z10 since about 2 years. It is driven by a Blackberry Enterprise Server 10 in our company and through this the Z10 connects via ActiveSync to our company's Domino server via its Traveler service. This ActiveSync connection and data is stored in the work area on the Z10 device. Using this setup, the Z10 has an average battery life of about 2 days (charging over night, then running one day, one night and another day with then a rest of around 10% in the battery before the next night's charge). After I created my personal e-mail/groupware server for the family during the last months (CentOS, Postfix, Dovecot, SOGo ...), I added another ActiveSync connection for my private e-mail account to the Z10's personal area. Setup was easy and it worked OK but after adding this connection I found that the battery of the Z10 lasts only one day and I need to charge every night! The Z10's "device monitor" shows that the "PIM Services" are the (by far) biggest source of battery drain (over 20%). After a week or so I finally removed that SOGo ActiveSync connection (but kept the work connection, of course). Battery life is back to two days and the device monitor shows the "PIM Services" using only between 5 and 10% of battery power, less than the base "System" itself. So why is using the SOGo ActiveSync connection so much more of a battery drain (e.g. CPU intensive)? Does it perhaps poll (no "push")?
