How to improve the Performance (Speed, RAM, Battery) of your Android Device

           Android devices made their entry in  smartphone markets with lot of expectations from users. In this race android was earlier lagging with the performance criteria and the most critical was the battery, as compared to the devices available at that time in market Android was having only one advantage and that is "Google". Since last 2-3 years Android has made a very good stand in smartphone markets and it has solved the very much performance related problems.
           For today's android devices average battery life is 1 day, we will see how to improve all the characteristics that in tern help increasing battery life and performance.
 Follow the below mentioned checklist

• First thing to check is the capacity of your battery it is mentioned in your devices manufacturer box or you can directly check it on the battery, the term is mentioned as MaH (Mili ampere Hours) e.g. 2000MaH
• This indicates the capacity of your battery and how much strength is provided to your android device
• Other part is to check what all sensors your device have excluding the common ones (proximity,gravity). This interns help you to know what is draining your devices battery
• If you are not using your Wi-Fi, GPS actively all the time disable it, as far as Wi-Fi is concerned it has option to auto disable when screen turns off, but GPS doesn't comes with this option.
• Install best battery saving application from play store as of now Juice Defender is best
• Check the performance of your fully charged  battery for entire day without recharging in whole day, you can check it in Settings->Battery
• It will give you clear idea what is eating the juice
• If your device have auto brightness option; use it ,it helps to increase your battery life almost 10-20%
• There is one more thing that drains your battery but you never notices it that is your processor, The highest capacity processor you have the high amount of battery consumption is made by device. To tackle this issue you can set up the CPU speed and tie it with various profiles. There are various applications like Set CPU, ROM Tool Box etc which actually helps you to monitor the speed of CPU, all these applications need root access, To know how to gain root access follow this link

 Improving  Speed and Ram optimization 

• As we have seen above the CPU speed is a key part in performance of your android. There are various options available like over clocking your CPU speed to higher one by installing new kernel which supports overclocking check out this post for Samsung Galaxy S duos 
• RAM of your device is also a key part in performance, to improve RAM optimization again you need to have supporting kernel and of course root access
• There are various options available to increase your existing RAM by adding swapping file on SD card, and they do work great.
