How to check Samsung Galaxy S4 CPU temperature? A simple question but no easy answer. So far I can’t find any Android application at Google Play Store that can display Galaxy S4 GT-I9500 CPU temperature. All of them are displaying battery temperature instead. This is not what I want. Luckily, I discovered that Samsung has its own application to do so. Not so user friendly but it does the job ~ show Galaxy S4 CPU temp. It is able to show Exynos 5 Octa CPU temp. It should work for GT-I9505 Qualcomm Snapdragon 600 too.

For those who are using faster bin Nexus 4 CPU, you are very lucky because your nexus 4 Qualcomm APQ8064 CPU is undervolt by default and use lesser battery (compare to Slow, Nominal and Fast). You can undervolt it further if you want to get even better battery life. Besides, it will help to generate less heat too. However, custom kernel that support CPU undervolting is required.

How to overclock Google Nexus 4 CPU? Well, it is not recommended. Yes, you can overclock nexus 4 Qualcomm APQ8064 CPU but it gets overheated easily. And will reduce CPU speed by itself to avoid overheat. Using faster bin Nexus 4 CPU does have better overclock ability though. By the way, you need to have custom kernel that support CPU overclocking. Default kernel won’t let you do so.
Note – overclock will reduce Qualcomm APQ8064 CPU, Adreno 320 GPU and other hardware components lifespan because it will overheat easily. Do it at your own risk.

The very first thing that I want to find out for long time after getting my Google Nexus 4 ~ how fast is the Qualcomm APQ8064 CPU chip inside? Slow, Nominal, Fast or Faster bin? The faster bin means you can overclock and undervolt better than other bins. So you can get better performance, battery life and generate less heat if configure correctly. Want to know yours? Just use Terminal Emulator to find out. Note – Root access is required.

Want to increase Google Nexus 7 battery life? Undervolt Nexus 7 NVIDIA Tegra 3 Super 4-PLUS-1 Quad Core CPU is one of the ways to do so. Besides Nexus 7 7″ HD WXGA IPS screen, Tegra 3 Quad Core CPU is another big battery eater. Undervolting helps to reduce Nexus 7 battery usage, and will make Nexus 7 cooler (generate less heat) too. Unlike underclock which may not be so efficient in performance / walt ratio. Undervolt surely will improve battery life because it maintains the overall performance speed while lower the battery usage. As usual, you need to install custom kernel for Nexus 7 in order to undervolt. Stock Nexus 7 kernel does not support it.
