Help Activesync Encryption draining battery? How to remove?

[stokesd3]

Installed my Corporate email on my Samsung S2 running Android 2.3.3 but found it to be a complete battery drain so have removed it again.

What I need to know is how to remove the encyption that it forced on my storage as part of the Device Administrator Policy as I assume it's still there? Have removed Exchange from the policy user list already. Thanks.

Shame no-one had any idea, Had to factory reset in the end and install everything again oh well

I don't think there is a way around it! I also have noticed that ActiveSync will kill the battery (in a matter of ~5hrs).

For future reference, the Enhanced Email app will circumvent the mandatory policies, so you don't have to cripple your phone if you want corp email.

Exchange Activesync, properly configured, should not kill any phone's battery. If it is, it is likely to be a faulty implementation in the email client. You might want to give Touchdown a try.

there isn't much room for error or faults when setting up an exchange account, it either works or it doesn't. and i'm using the standard vanilla email client that came with the S2.

will try touchdown to see if battery life will improve. thanks for the tips!

It isn't a matter of setup. Some email clients don't observe the EAS communications protocols properly/completely so while they "work" they keep the data connection open more than it needs to be, hence draining the battery.

I always keep wifi and mobile data off during the day, and wifi at home, so wouldn't have been sync-ing. Removing EAS (NHS email in UK) has transformed the battery life - it's over twice as long as my desire ever managed!
I wonder if its the file encryption that puts an added system processing burden?
