E-mail sync downloads more data after Froyo update

Hi

After updating Android to 2.2 Froyo, I noticed that my daily amount of downloaded data increased. After some days of experimenting, I think I have found the e-mail sync to be the reason. Before the 2.2 update, NetCounter reported around 300 kb of downloaded data a day when I was not using any “internet apps”. After the update, it is around 1500 kb. I sync to e-mail accounts: A personal IMAP once an hour and an Exchange account by push. Setting the Exchange account to sync every hour doesn’t affect the result much. However, if I disable sync of the two accounts, it’s reduced to < 100 kb a day.

Today I also noticed that after opening my Exchange account which haven’t been synced for 1½ day, it immediately used 600 kb. Considering that only 6-7 mails were added, this seems very strange to me. I get the impression that only headers were downloaded prior to 2.2, but now the entire body, including some attachments, are downloaded when synching.

Has anyone else noticed this behavior? I know 1500 kb doesn’t seem like a lot, but my company only pays for a fairly small amount of traffic, so a 5 times increase shows

Phone info:
GT-I9000, baseband version I9000XXJPM, build# FROYO.XWJP6

I seem to have been spared most of the e-mails application speed issues. While synchronization speed might have dropped a bit, I haven’t noticed any major slowdowns when opening the client or handling e-mails. Do you (and others with the same problem) also experience this when connected to WiFi or is it only when on a mobile network (which would make sense if the two things are related)?

Not only more data, but worse battery also: setting the Email retrieval update interval to anything else than 'Never' results in a continious 10% CPU load, even while the phone is asleep, draining the battery two times faster than in Eclair 2.1

I set it to 'Never', or have Tasker kill the Email app x seconds after Display Off

Determined by using System Panel app.

Try this:
- a factory reset....., No really, factory resetting makes Froyo perform much better. Reported by many Galaxy users (including me)
- set the retrieval interval to "Never"or "Push", not to a time schedule (i.e. 15 minutes)
- Look into "Improved Email" at http://www.mwebster.us/: ability to sync specific subfolders, hide subfolders, apply color of your choice to the account. Tip: first delete exisiting Exchange account and setup a new account from within the improved email app

Yes, I have received my new Galaxy S on Sunday and was surprised today by a SMS from my Service Provider that I have used 70% of my data bundle. (I had configure my e-mail to sync last two weeks and it did so with ALL the attachments. Previously I had an HTC where you could choose / configure to only sync the headers and then downlod only thoose attachements you want. I am very dissapointed there is no easy fix to this problem. I did good research on the Galaxy S, HTC Desire HD and iPhone 4 and on price performance the Galaxy S comes tops but now I am going to pay on data bundle.

Is there no fix / advanced configuration settings for this??

I installed froyo using Kies - no problem. But now my email is not so slow it's unusable.
Samsung say there are known incompatibilities with froyo and service-provider-supplied phones.
They suggested I go back to the previous version of Android!
I tried 2 of the Samsung service centres, but neither of them knew what I was talking about and could do nothing to help.
The alternative they proposed was to mail it to them for fixing, a process taking 2 weeks.

Today I have good news.
According to Vodafone http://forum.vodafone.co.uk/forum-73/announcement-51-firmware-related-queries/ (my service provider), this kind of problem is covered under warranty.

"Any update that users are prompted to download to their device through an official channel
(either by the manufacturer or Vodafone directly) is classed as an official update.
For example, if you are told an update is available for your Samsung Galaxy S
through Samsung’s Kies PC Sync software, your warranty won’t be impacted if you choose to install it."

So if you upgraded using Kies, and there are problems, call your service provider and ask them to fix it!

For those who are experiencing exchange email problems after upgrading to Froyo 2.2, I have found a temporary work around. Try TouchDown ... it saved my day ! I can now work my exchange emails again. There is a 30 day free trial period, hopefully there will be an updated Froyo 2.2x released before then ! (btw - this is NOT an ad and I do NOT work for TouchDown ... just a genuinely frustrated Froyo 2.2'er)

It is always a good practice to start with a "clean" device by Hard/Factory Reset after updating/flashing its firmware.
