Is it stable enough?
Yes, I’ve run the benchmarks for about 10 times straight, my phone got super hot but no reboots, nothing!
So, if you do want to supercharge your Note 3, definitely give the Lean kernel a try and do let me know what is the highest Antutu benchmark scores you were able to get! Or if you were able to use another kernel, let me know what kernel/settings you used.
Note – To get the correct benchmarks scores, make sure your phone cools down all the way before running Antutu. Running them one after another will cause your CPU to get hot and your results may be hindered.
How to Install Lean kernel?
You can install Lean kernel of the following Note 3 running Android 5.0 Lollipop.
Download Lean Kernel for TouchWiz Lollipop – SM-N9005, T-Mobile SM-N900T, Canadian SM-N900W8 (These are the versions I used since performance may be different on other versions, try this one first then if you get it working, get the latest version here.) This can be installed on any Note 3 running latest Lollipop TouchWiz ROM/stock ROM.
