Android 4.1.1 consumes too much memory My HTC One S has been upgraded to 4.1.1 and I noticed that it started consuming too much memory.

When I had 4.0, average memory consumption was about 300-450 MB. But now it is on the level of 700-850 MB. Is this a normal situation for the current version of Android or did something go wrong after the upgrade? 

All system apps were upgraded with the OS. I have 1 GB of RAM.
This could count as a good sign: There should not be such a thing as "unused RAM". Linux and Android in special do a good job to make the best use of it by caching things. If there is any RAM not currently needed by running apps, it can be used to keep e.g. pieces of the file system for faster access -- which also helps to save battery life. Once there is additional RAM needed, those caches are the first things to be cleared.

For more details, I recommend to take a look at the following related questions and their answers:

Are there guidelines on how much free RAM a phone should have?
