These are few tips:
Know Your Device
It is important that you learn about the capabilities and drawbacks of your phone. Don’t overburden your phone with resource-hungry apps which would otherwise degrade your phone’s performance at your expense.
Update Your Android
If you haven’t updated your Android phone to the latest firmware, you should. Google brings great improvements to each new release of the Android operating system, including updates that ensure stability, higher performance speed and connectivity along with other user-friendly new features.
Tablets can also run on ICS and Jelly Bean now; you should be able to update it until Android 4.1 Jelly Bean via System updates (Check under ‘About phone’).
Remove Unwanted Apps
Every app you install in your phone take some storage space and runs some background processes. The more storage space occupied or the more background processes running on your phone, the slower your phone’s performance many of us have load of apps in our Android phones or tablets, the applications we never use. Your first most step should be removing those apps completely.
Go to settings and then apps
Tap on “Running” tab
Check which apps you’re not using and tap on “Stop”.
Uninstall the apps you see in “Running” tab that you don’t use. You can uninstall these apps from “Downloaded” tab.
Don’t install apps you hardly use
Keep only the apps that you need and if you have got an app that isn’t really useful, you can uninstall or disable it.
Disable Unnecessary Apps
Performance assistant’ was introduced in Android ICS to help you disable apps that you don’t need. Disabling apps is different from uninstalling apps remove application files from the phone but no file is removed/deleted when you disable it. These disabled apps are not shown on the home screen or app tray but you can re-enable them for use whenever you need them.
Use High-Speed Memory Card
The memory card is the storage space of your phone. Phones with low internal memory can get a boost from high-capacity memory cards for maximum storage space. But it adds not only capacity but also speed to the mix. You can get between 2GB to 32GB worth of storage space to support high speed read/write operations. Always go for memory cards of Class 6 or Class 10 for your Android phone if you seek performance for your phone.
Keep Fewer Widgets
Widgets are not apps, which only run once you choose to activate them. No, widgets are always running in the background; they are active all the time. While some Android users use it to keep track of the weather, and their important dates, others use widgets like ‘Extended controls’ for quick access for essential configurations such as switching Wi-Fi, Bluetooth or their GPS on or off.
They do have their uses but bear in mind that having too many of them running on your home screen will cause your device’s performance to slow down.
Avoid Live Wallpapers
You must be loving Android’s live wallpaper feature. Phones (from different manufacturers) come with different live wallpapers but you should know that live wallpapers that are badly made will need more CPU cycles to run, thus draining the battery faster. Every time you activate the home screen, you run not only your apps but also your live wallpaper.
Sync is a very good feature that synchronizes your data with Google servers. Keeping sync on, you can get notifications whenever new mail comes in or when you get new notifications or updates for apps. To do this, it does a refresh at every preset interval (e.g. it checks your mail every 5 minutes for new incoming mail), and this will eat into your android’s performance for other activities. You can keep Sync off for unrequited services or only have it on when you need to transfer or upload materials to Google servers.
Turn off Animations
What animations? Well, if you haven’t noticed, your phone screen actually fades out and in as you switch from one task to the other.
To see this in action Go to Settings > Developer Options > Window Animation Scale > Animation scale 10x. Then choose Window Animation Scale again to see the fade-in effect in ‘slow-mo’. When you choose Animation off, the screen just snaps to position without animation. You can also turn off Transition Animation Scale in the same way. If you are a heavy user, you’d probably notice that your Android performs faster with all animations off.
Use Lightweight Background Apps
Everyone enjoys listening to music but imagine how much memory the music player app requires to play a whole album for you. It’s the same with other types of background apps you may have. Use lightweight apps for these purposes, e.g., you can install a music player that requires 1 MB installation space (and thus less RAM too) than the ones requiring 10 MB or more. This way, your phone will have more free memory, boosting your phone’s battery and performance.
Turn off Maps
The moment you open your tablet, your map application will be active especially if you’re always connected to the internet. If you have GPS on your tablet, that’s worse. Not only will this suck the life out of your battery, but it will reduce your tablet’s performance. How? The tablet’s system will cut out on your tablet’s performance to make your tablet last longer.
Transfer apps to the SD card
One of the biggest problems, especially of mid-range Android smartphones and tablets is that the built-in storage is really low. There are some apps that cannot be transferred to the SD card, but most of the apps available on the Play store can be moved to the SD card.
It is easier to clean up the memory card by deleting leftover folders from uninstalled apps and also simpler to transfer data from your PC to the device.
Background data and connectivity options
The beauty of Android is that it is very easy to sync your contacts, apps and other information seamlessly between devices. Unfortunately, the background sync depletes the device’s battery life in a jiffy. Disabling background sync will help you save on the battery life of the Smartphone. It is easy to manually sync your Android device with a simple click of a button. You can also enable selective sync if there are apps and information you would like updated all the time.
On your Android Smartphone or tablet, you have a bunch of connectivity options such as 3G, Wi-Fi, Bluetooth, and GPS. Sure, all these connectivity options are great to use but you won’t use them all the time. It makes sense for you to disable these functions when they aren’t in operation. Switch on the Wi-Fi when you are in a Wi-Fi zone and switch it off when you leave it. When you aren’t using the Internet on your Smartphone, it makes sense for you to switch to 2G as 3G is very power-hungry. GPS and location services too can be switched off after you have checked-in or finished using Google Maps.
Setting the display brightness to auto will help you save the battery but it is better if you manually control the brightness and set it to as low as you’d feel comfortable with. The screen is one the biggest battery drainers and if you are someone who has a behemoth of a Smartphone with a large display, you will see a noticeable bump in battery life with lowered display brightness.
You can add a power control widget on the home screen that lets you control the Wi-Fi, Bluetooth GPS and other settings with brightness controls. Some Smartphone makers give you these options in the drop down notification area.
Manage Google Services
An Android device automatically includes access to Google services including Books, Contacts, Currents, Gmail and Google+. If you don’t need these services, turn them off and save your wireless radio the trouble of downloading more data (pictured below).
Open the Settings app on your phone.
Delete the Google services you do not want synced.
Click Accounts and select the appropriate service.
