Hi Alban -- If the default isn't working for you, you can change the attachment size that the app uses in the settings (see Work with attachments—Collector for ArcGIS | ArcGIS for complete steps how). One of the options is "Actual" and it will use the full resolution photo.
You mentioned that "Collector for iOS and Android both compress the photos before adding them as attachments in both the online and offline scenarios so that will help drop the size." Any idea what size this actually is? Is it 1.6 MB/photo as Peter mentioned above?
Also, with the current version of collector 10.2.5 has the amount of data one can sync to hosted feature services changed since your last post that you know of (2GB for iOS and 200MB for Android)?
Thanks! I'm just looking for some clarifications on these two points. I looked around the forum and wasn't able to find any updated info.
Great to hear android supports the 2GB sync as well.
I have a project coming up where I will be taking hundreds probably thousands of photos by the end. Some surveyors will be using android (through testing I know I can get image size to around 750KB/photo). However for iOS devices is there a default compression size for the app? I'm seeing 1.6MB in some forums and other Collector resources online. If this is the case, I will probably need to use a 3rd party compression app for iOS field photos.
Just wanted to confirm a piece of information I heard at the UC this year. Regarding AGOL credit usage, attachments are NOW stored under the "Data Storage" category correct? (1.2 cr/ 1GB a month? ArcGIS Online | Service Credits)
Thanks for the clarification.
Yes newly published hosted feature services generated after the last AGOL update will run through this storage model. This info was also included in the AGOL update email "Whats New" for the July release and in the Whats new release notes under the AGOL docs.

Under the Services section
We are providing file-based storage for attachments in hosted features layers. Attachments included in hosted feature layers are stored as files instead of features, reducing your organization’s credit costs for storing feature services. "
Under Hosted Features and Tiles section
Attachments added to hosted feature layers after July 2, 2014, are now stored as files, reducing storage costs for your organization.
Yeah that makes sense,
Wasn't sure if there was a general compression range for iOS without using 3rd party compression apps. I'll have to test it out, sounds like it varies.
Thanks for the responses.
