I recently got a 700wx, switched from a 700p. I was REALLY disappointed with the battery life on the phone. Even on a full battery, by about 6pm the phone was pretty much drained.
I figured Goodlink (corporate push email) was probably the culprit, so I uninstalled it so I could run some tests. Turns out the battery drained just as fast without goodlink. The phone was constantly warm like the radio was stuck on all the time. I finally turned off regular IMAP retrieval, which I had going ever 1/2 hour to my personal email account. Battery life went thru the roof - at the same time in the evening my battery was still at 75%.
Now I need to be able to sync email, so I was pretty bummed, so I did some experimenting. What I found interesting is that there are two places to specify how often email is retrieved. The first place is in the account settings, on the last page, if you hit the options button, you can specify how often to check email and whether to download the entire message, etc. The second place is from the Menu softkey in the inbox, there is a menu item, Delivery Preferences, that also allows you to specify retrieval times.
Here is the kicker: when I had BOTH retrieval schedules checked at 30 minute retrievals, the WM5 inbox got direct push email from my IMAP account. There was about a 30 second delay, but it was like WM5 knew when it needed to go download an email. It also caused the radio to be on almost permanently, which accounted for the massive battery drain. Now for personal email, instant delivery isn't that important, I prefer the longer battery life. Once I unchecked the retrieval schedule from the Delivery Preferences menu, email behaved and checked email every 30 minutes. Battery life is great and I get email sync every 30 minutes.
I'm still intrigued by the push IMAP email phenomenon. Has anyone else experienced this? Does anyone know what the point of having 2 retrieval settings is?
