Overclock Snapdragon 800 to match Snapdragon 805 Frequency!
There are always processors that can be overclocked more than others and if you are a Note 3 user, you are in luck as Qualcomm 800 can be easily overclocked from its stock 2.3Ghz to 2.726Ghz no problem, giving you nearly 20% boost. And yes, overclocking it that much will give you decreased battery life but in my testing the battery life still outperformed one on Note 4 (due to 1080P instead of 1440P screen and your screen eats up most of your battery life, not CPU).
For my overclocking experiment, I wanted to get the best operating system running so I loaded the latest Android 5.0 TouchWiz firmware on my T-Mobile Note 3 and also the latest CM12 nightly on my SM-N9005, both with Leak kernel installed.
Kernel of Choice for Note 3 Overclockers – Lean Kernel!
Lean Kernel is probably the best custom kernel you can use for your Note 3 for overclocking as the developer has been around and makes some excellent kernels. It is available for most Note 3 variants without a locked bootloader.
When I first did my benchmarking tests with Antutu fully overclocked to 2.726Ghz, I actually didn’t get better results. In fact, my scores were lower than stock at times. There’s one little change I made a big difference. I knew from my experiences overclocking Litecoin rigs (for making crypto-currency) that sometimes you can undervolt your highest frequencies to bring the temperature down. I did exactly that, turned voltage at 2.726Ghz from 1170 to 1140. And the results were amazing, I was finally able to break through 48K on Antutu benchmarks! (My stock Note 4 on KitKat did 46K on Antutu.)
