I have a question regarding email synchronization. If I send an email to my e.email address I immediately (2-3 seconds) receive a notification on my phone.
I tried to modify the sync-frequency in the email-app and even set it to manual sync and disabled email-sync in the account manager for the /e/ account. Still the notifications for new emails appears immediately.
The reason I ask is that the email app needs a lot of battery (>25%) on my phone and I think that is not normal. Has anybody similar issues?

This is happening because IMAP push is enabled in the mail app by
default. This means that the app maintains a connection to the IMAP
server to be notified of changes immediately. You can disable this as
Thanks a lot for the answer. Do you think the Push setting can cause the battery drain?
I think it can, I have noticed it draining my battery when I had
multiple accounts configured with push enabled at one point. Battery
consumption was considerably lower when I disabled the push setting.
I applied the tips in this topic and hope it’ll help. But I also noticed that under ‘account settings > advanced’ there is a ‘Poll when connecting for push’ box checked. According to this website “When this is enabled K-9 Mail will do a full folder synchronization after establishing a Push connection. Otherwise it will only download new messages.”
To me this seems this is the underlying reason for the battery drainage when push is enabled. And maybe if this assumption is right, the ‘Poll when connecting for push’ box should be unchecked in the default settings.
