Benefits of Rooting Android Phones/Tablets

Let’s take a quick look at some of the points why do Android enthusiasts like to root Android phones and tablets, even when they know this could harm their devices in several ways if done anything wrong.

You may have a look on Android rooting - Brief Discussion 

Flashing Custom ROMs :

If your Android phone or tablet is not rooted, you wont be able to run custom ROMs. Why install custom firmware on your phone? Because they not only improve and optimize the Android system but can even give you a new UI and come with amazing features which sometimes can turn out to be really useful improvements for your Android device. your device becomes a lot faster, stable and gets a major performance boost.
Most of these optimizations and features cannot be usually installed on a default Android system since you are not allowed to modify the system files.

Overclock CPU :

Rooting a device gives you the ability to overclock its processor. That means you can increase the clock speed of a 1GHz processor, in some cases, to as high as 1.6GHz, for example, which should translate into a pretty significant bump up in processing speed.
Combining overclocking with Custom ROMs can result in massive uplifts in the performance of your handset. We’ve heard reports of a Nexus S running with an overall increased performance of 250 per cent after a series of expertly implemented tweaks.
A bump of 250 per cent, we’d imagine, is rare and requires a lot of skill to achieve, but it does illustrate profoundly just what can be accomplished once your device is rooted.
It’s worth noting that a lot of top level modding such as this requires a very precise set of skill and knowledge, so we would advise anyone not comfortable with the science behind overclocking to proceed with caution. No-one wants to brick their brand new phone, after all.

NOTE: It is advised not to overclock too much. For example, if you have an Android phone with a 800MHz CPU, you should only overclock it to around 900MHz. Or if you have a dual-core/quad-core CPU, you should not overclock it by more than 300MHz. You also have to do some research on your device’s stable overclock limit before proceeding any further.

Move Apps from Internal Storage to SD Card :

This is our favourite for budget and low-end Android phones. If you are running low on internal storage, you can move almost every app to your SD Card. This frees up internal storage for system use and makes your internal storage clean and tidy — and also allows you to install a lot more apps n your phone!

Modify System Files, Deep into Android OS :

Root also allows you to explore system apps and even modify them to your specific need. This will help you to get ported features by developers on your phone and even give you the opportunity to modify yourself. Running low on space? You can delete unnecessary system apps and gather up some useful space all with rooting your phone. This could be useful for budget Android phones that don’t come with a lot of internal storage.

Backup Android Phone with Nandroid :

This requires you to have a custom recovery (preferably: ClockworkMod Recovery). No need to use a computer to backup Android apps, contacts and other personal data. When you root, you have the option to install a custom recovery on your phone.
This recovery allows you to install custom firmware and most importantly, you can save the current state of your Android phone or tablet using the backup option (Nandroid) there.You will be able to save every preference, setting and app right to the phone and can easily restore your things whenever you want, thus simplifying everything and making it very easy. This is what we always suggest to do before trying out a new custom ROM or a risky system tweak.

Advanced Task Managers – Save Battery :

If you use a lot of apps within a day then you probably are a victim of unnecessary battery lost because all of the apps you run stay in the RAM for quite a long time even though you have closed them. This is where an advanced task managers come in. Their purpose is to kill tasks that are running in the background and always draining your battery. Once you have rooted your phone you can find several free advanced task killers that periodically clean up your RAM and help you save up battery.

Root-only applications :

With a rooted device you also get access to plenty of bespoke applications, which can seriously add to the performance and utility of your handset. Here’s a selection of some notable examples:

• DroidWall
• Dual Mount SD Widget
• Hexamob Recovery Pro
• Keyboard Manager
• LEDs Hack
• Rot Call Blocker
• Samba Filesharing 
• Titanium Backup

Improve Battery Life :

A lot of Custom ROMs will improve your battery life via the removal of bloatware and unnecessary applications that hinder performance. There are plenty of power management apps out there, such as Superpower, but most work significantly better when combined with a finely tuned rooted handset.
Rooting can’t work miracles for your battery life, extending it beyond its natural limits, but it can ensure that you get an extra few hours a day from your device. And sometimes that’s all you really need.
