Any evidence to support the claim that the Yahoo mail app from the market is a battery drainer? I've been using it for months and haven't noticed any unusual wake locks nor have I ever seen the app on the battery usage list like games and the screen and what have you... Am I missing something? It also seems to support true push which should ideally be more efficient than any IMAP polling.
As far as the app itself, yes it's very lacking in options... I hate that they made it so that deleting or moving a message while it's open automatically takes you to the next one (i prefer getting kicked back to inbox, as it used to work). Other than that I don't have a lot of complaints since I do zero message composing from that app, I just use my Yahoo address for bills and like shopping newsletters, forum thread subscriptions, etc. I use Gmail for personal stuff, any actual conversation, photos, etc.
Yahoo's app does beat Gmail when it comes to attachments imo, it lets you download any kind of file and usually does it quicker. /shrug Gmail forces a preview of some files, ignores others, etc. At least you can get around Gmail's sending restrictions by attaching stuff from within a file explorer like EStrong.
Edit: I assumed it supported some sort of push method (since FB notification emails were instant) but I see there's quite a lot of complaints about it's battery use (and yet it still has a 4 star rating...), is there any way I can see this drain for myself besides uninstalling and hoping I notice the difference? They couldn't possibly have it polling every few minutes by default as people claim could they, that just seems insane... I think I originally downloaded it to get access to my mail folders & search functionality, neither of which the stock mail app was doing... Is this something K9 can do?
