Nexus 7 2013 Update (Over Clock)

So, I still have ElementalX  installed on my Nexus 7 2o13. I bought the app in the play store called “EX Kernel Manager“. It basically allows you to manage the kernel within the OS. A little while ago I returned my Nexus 7 to stock speeds to see what difference overclocking actually made. Much slower. Games dropped in FPS and things loaded slower. Now, overclocking it for so long has taken its toll. When I open the back of the tablet, there are some very visible burn marks on the metal. For some reason, (this just started recently) when I try to load anything, it takes wayyy to long. My Nexus 7 2012 can beat it! I uninstalled Ex and everything went back to normal (besides the lag due to the slower CPU and GPU times). I still can’t figure out what is causing this. For an example, if I open YouTube after removing it from memory, it takes a long time to load. If I open a a game, say Clash Royale (I like it, your opinion may vary) it gets stuck at 81% and very slowly climbs its way up to 100%…. I timed it and it took about 45 seconds. For reference, my S6 can do it in around 15 seconds. That really is the negative part of my rant. On to the positive!

ElementalX has a lot of neat features also (the reason why I have not uninstalled it). I have already mentioned a few in a previous post (Here). The main features that I use in everyday life are Dimmer Backlight, Overclock, and Fast charge. There are a lot more that I occasionally use. The speaker boost feature is nice in loud situations. You can disable the magnet sensor that turns the screen off/on. I used to use “Swipe to wake” and “Double tap to wake” however, I stopped using this because of a digitizer issue. I would still use that feature if my Nexus 7 didn’t have that issue, although I am pretty sure every Nexus 7 has that issue (Leaving the digitizer on for too long causes some funky side effects). Alot of these features honestly should have been enabled by default honestly. Overall, after using ElementalX for almost 7 months, I would still recommend it!

Over Clocking the Nexus 7

Back Story

I have had my Nexus 7 for awhile. I love it! It may be old, but old is gold (hehe). The Nexus 7 isn’t showing its age even with Android Lollipop and over 100 apps. Of course someday it will begin to show its age as apps update and require more power. I only noticed some sluggishness when I was playing 2D games. I do not know what caused this but it was very annoying. It went from anywhere between 15-60 fps. It would purge real fast and slow down too. I noticed the occasional lag when multitasking. None of these things really bothered me at all.

Over Clocking

I decided to overclock my Nexus 7 mostly for the fun of it. I was interested to see how much I could get out of my tablet. The Nexus 7 has a Snapdragon 600 (I’m pretty darn sure) that is under-clocked to 1.5 GHz and marketed as a S4 Pro. I am not sure why they do this. Maybe it is to keep the heat down or maybe it’s because the Nexus 7 uses a chip that had issues running at 1.89 GHz and they just under-clocked otherwise it would be a waste just to throw the processors that still could be used. How did I do it? To do this, I installed ElementalX. I downloaded the recovery installer. ElementalX uses that aroma installer which makes it easy to select the settings that best fit your needs. I set my CPU clock to 1.89 GHz and my GPU clock to 490 MHz. Changing the GPU clock speed for what ever reason boosted 2D games FPS significantly. I disabled the swipe to wake-up features but kept the double tap to wake enabled (It is really nice especially if it’s on a desk and you want to change the music while holding a calculator or whatever you are doing with your other hand) I also installed the ElementalX app. It allows you to change all of the things that the ElementalX kernel offers without having to reboot into recovery and reinstall the ElementalX kernel just to tweak something minor. The tablet did get a little hotter during more demanding tasks (to be expected)

The Result

I got quite a bit more performance out of my tablet and I really did not loose that much battery life. I did some benchmarks and beat the crap out of the stock Nexus 7. The ElementalX kernel also has a lot of other features too in case you don’t feel like overclocking. There are features like faster battery charging, battery saving mode (it makes the battery charge to 97% ish to save the overall battery life), double tap to wake, dimmer back light, and make your speakers MUCH louder. I made the speakers over 50% louder than they where originally attended to do. The entire tablet vibrated….. I strongly advise you NOT to do this though.
