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.
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)
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.
