PERFORMENCE Using i Tunes The full update is likely to be more stable There the possibility of minus glitches EXPLICATION i Tunes always downloads the full OS and installs it.

Given that Apple allows people to update i OS either way, they are both good choices.

However, my long career in IT leads me to be wary of overlaying new stuff on old, and I prefer to do the i Tunes method.

While I can't say as I know this, I assume the larger file is there to do a complete replacement, rather than a patch.

Well the big notice difference as you mention above is Starting with OTA/ Over the Air For some people who are confuse OTA and Over the Air means the same thing.

FILE size The OTA updates provides a delta update only while i Tunes provided the whole build.

Delta include small size while whole build unpack the big file using PC or Mac on my experience I have 2 i Phone's updating via i Tunes the file size to each device is completely different i Phone 5 1.5Gb i Phone 5S 1.7Gb and I would understand that for newer i OS devices is to much larger ADVICE from apple Tech support If there is a problem after installing the delta update OTA, restoring the i Phone with i Tunes to install the whole build for the update may resolve the problem.

The most common problems are: Battery life, Wi/Fi Problem, Blue Tooth Issue, or Software Bug.

Friends, I want to understand the difference between updating i OS through OTA VS through ITunes.

I see that the update size on ITunes for i OS 8.3 is more than 1 GB as oppose to about 280 MB through OTA.

Is there any difference between the end result of downloading through Itunes ?

I understand that ITunes downloads the whole build, but does it make any difference?
