How to Extend Lava Iris X8 Battery Capacity

Your Iris X8 2500mAh battery is not enough to power your 8x core processor and HD resolution. For this you need to follow these simple steps to make your phone battery a little longer. This methods is helpful for all android smartphone users.

• Calibrating your phone battery helps you to extend your phone battery capacity and life both. Though its not possible for some of the user living in UP and Punjab region (especially me) I mark this most essential step as optional. Calibrating is easy but requires a lot of time, you first need to drain your phone battery by using light applications for once and then after it drains to 0%, charge it for full 100% on power off. Repeat this process once again and you're battery is now calibrated. 
• CPU power saving mode - this option is available in battery settings. By checking it means the phone now limits the maximum CPU performance and converse the battery life. Also helpful to reduce overheating which is not in general. Disable it while gaming for optimal performance.
• Check for any unwanted/highjacking installer app. Well its very simple to look for such app, just head to your Data Usage and search for the suspicious app. Beware not to uninstall any system app.
• Limit administrator rights to any third party app. 
• L Launcher works great for me in place of stock AOSP Home launcher. Give it a try, best for optimizing phone performance and in comparison to stocks consume very little amount of primary memory.   
• Use Greenify app after rooting your phone. With greenify you can hibernate more than app at once. Hibernate is actually force closing the app which greenify perform it faster than manually. Works fine for me and must be for you, also it is suggested by users worldwide.
• Use Cooler Master app to clean unwanted background process. Cooler Master requires administrator rights and works as a simple app cleaner but sort out application process in accordance to overheating. Well in general overheating leads to battery drainage. This app works helps and is lighter than other cleaner apps.
• Disable Flip Cover functions, read this article to disable it.
• Disable Float Task, Smart Gestures, Clear Motion, Daydream, Set default screen lock from Settings. 
• Other method includes - using a dark background, keep low brightness level, disable WiFi, GPS, Bluetooth when not in use, Keep radio off and set timeout to as low as possible also contributes a lot. 

I hope these methods works there is also a traditional way which helps you to extend battery capacity is mentioned in My Android Phone blog, here is the link.
