Redmi 1S - JHCMIBH45.0 update released, OTA

Another update for the Redmi 1S JHCMIBH45.0 is on OTA after the release of JHCMIBH43.0 less than two weeks ago. There is only a single description in the changelog, which is 'improved security of Cloud Messaging'. It is not known what other changes are done under the hood, which is typical of Xiaomi's update changelogs.

Xiaomi devs have implemented some kind of thermal control and aggressive throttling of the CPU when it reaches a certain temperature. UI is not as responsive, and games aren't as smooth as it used to be. Battery life seems to be worse than previous versions.

Additional changelog item is listed on the MIUI forums.

System - New : Optimized RAM usage (10-05)

Later, these entries were added to the OTA changelog:

System - Added thermal control to prevent the device from overheating (10-13)
             - Optimized RAM usage to prevent background apps from getting killed (10-05)

Messaging - Improved the security of Cloud Messaging (08-10)

Update and changelog.

Limit background processes

There seem to be an additional option in the 'Settings > Battery'  section. Where you can 'limit background processes'. There is no information about how many background processes are allowed when you enable this feature. This same feature can be accessed in the 'Settings > Developer options' section. Scroll down to the bottom and choose 'Background process limit'.

Here you can select:

- Standard limit
- No background processes
- At most, 1 processes
- At most, 2 processes
- At most, 3 processes
- At most, 4 processes

*Update (13/10/2014) : Previously this version was released to selective Indian users OTA. It is now released for the rest of the users.

*Update (14/10/2014) : New changelog up on the official forums. Now Xiaomi has decided to release more items in the changelog. Fickle or not I don't know.
