G+_Marlon Thompson Posted July 28, 2013 Share Posted July 28, 2013 Good news new Nexus 7 shouldn't experience the ageing problems of the original and 4.3 rejuvenates the old Nexus 7 Just read Anand Tech's "short" review of the Nexus 7 and it is impressive.one of the most interesting points the make is quoted below. The story actually is a bit more involved however. One of the big problems was that the slowness which occurred with the prior Nexus 7 took device aging to appear – it was great for the first few months, but after you started loading it things tailed off. The new Nexus 7 (2013) with Android 4.3 includes support for fstrim, essentially idle garbage collection, which TRIMs the eMMC when a few conditions are met – the device is idle, screen off, and battery above roughly 70-percent. I’m told that TRIM support has been part of the eMMC standard since around version 4.2, it was just a matter of enabling it in software. The result is that the new Nexus 7 shouldn’t have these aging affects at all. Better yet, fstrim support has also been added to the old Nexus 7 with as of the Android 4.3 update, so if you’ve got a Nexus 7 that feels slow, I/O performance should get better after fstrim runs in the background. So Jason Howell and Gina Trapani don't throw out that old Nexus 7 yet. This feature may also be a part of new nexus devices going forward so it makes another compelling reason to go nexus.

G+_Marlon Thompson Posted July 28, 2013 Author Share Posted July 28, 2013 Sorry I forgot to link the article. Joshua Hughes the writer suggest that this could be a feature going forward, with OEM's you have no guarantee that they will implement it the same way Link to comment Share on other sites More sharing options...
G+_Robert Nazarian Posted July 28, 2013 Share Posted July 28, 2013 I would assume if you have an old Nexus 7, the 4.3 update might not be enough. A hard reset would also be necessary to get rid of any other clutter from prior to the update. Link to comment Share on other sites More sharing options...

G+_Johan Appelgren Posted July 30, 2013 Share Posted July 30, 2013 Robert Nazarian Why wouldn't it? From the article: "The Android framework will send out a “start idle maintenance window” event that the MountService listens for, and then invokes vold to fstrim filesystems when a few conditions have been met – the device hasn’t been touched for over an hour, no idle maintenance window event has been sent in 24 hours, and the device is either off-charger with 80% battery or on-charger with 30% battery. The goal is to have fstrim run roughly once every 24 hours if you’re in the habit of plugging the device in to charge every night." Link to comment Share on other sites More sharing options...
