Want to know how much frames per second (FPS) does your games run on your Android device? Well, there is a free an application that can do so. GameBench is the one. It can provide detailed CPU, GPU performance and battery analysis on Android devices. So that you can identify the bottleneck of the game or application. By the way, root access is required. Don’t have? No worry, one-time PC connection setup can solve it.
Get better battery life on your Samsung Galaxy S4 by undervolt CPU voltage. Yes, set lower CPU voltage values below the default one. This will reduce battery usage. Of course, you need to make sure that your Galaxy S4 will still be stable with lowered CPU voltage for both ARM big.LITTLE CPU cores. Else no point to save battery life by doing this if always faces hang or system not responding issues. By the way, undervolting CPU also helps to reduce overheat issue too.
Samsung Galaxy S4 GT-I9500 is not fast enough for you? Try to overclock CPU then. Personally, I don’t prefer people to overclock small devices because they will overheat quickly. Make it too warm / hot to hold. So I only overclock to show off how great my Galaxy S4 can perform, not in daily usage because Malaysia weather is too warm. It will overheat over 60 °C easily. Yes, you can still overclock Galaxy S4 CPU. Just make sure that its temp is below 50 °C (or as cool as possible). Remember that overclock will shorten battery life too because it uses more voltage…
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.
