We know that the performance of Nexus tablets and other Android tablets and phones slow down with the passage of time. But this TRIM feature in new Android OS keeps record of garbage data blocks and pages and informs the SSD or eMMC controller about this not needed data. It means that TRIM will tell flash storage controller the right time to collect and recycle unused data.
This will increase device performance at any age. Hence performance of all devices running Android 4.3 will be improved. But a limitation is there. 80% battery without charging or 39% battery with charging is required for TRIM feature to work. Android 4.3 Jelly Bean OS runs TRIM once in every 24-hours after an hour of inactivity.
New Nexus 7 is a much improved Android tablet now with 4.3 Jelly Bean OS. But previous Nexus and other Android users can also improve the performance of their devices by updating latest 4.3 OS.
