Issues can arise with a wall outlet, charger or battery. Refer to the solutions provided under " Redmi 2 battery charges slowly" to relieve these problems .
The power settings on your Redmi 2 may be set to ’enhanced’ instead of ‘balanced.’ An ’enhanced’ setting will keep your phones screen brightness at the highest level whenever possible, execute full usage of any apps you use, and induce all screen effects, such as the movement of an app when you press it. Your phone will reduce the screen brightness when possible , use a low amount of energy for each app, and reduce any screen effects by changing this setting to ‘balanced.’ This setting change should improve battery life.
Since there are many different apps a phone can contain, whether they come with the phone (a photo gallery, notepad), or can be downloaded (social media apps, games) they have the possibility to use much of your battery, even when you aren’t using them. Completely close apps when you are done using them, to increase your battery life.
If the adjustments to charging methods, background app usage, and power settings do not improve the longevity of your battery life, it may be defective or has exceeded it’s useful life. The battery should be replaced to solve this issue.

If the microSD card is not the proper model for the Redmi 2, the incompatibility can cause the motherboard to work overtime. This extra work overheats the phone and can damage it. Replace the microSD card with the compatible model.
When charging your Redmi 2, the phone is receiving heat from the outlet. Once the phone is fully charged, you must remove it from the charger.
If you use your phone constantly throughout the day, it can cause the battery, and others parts of the phone, to become worn out. Try to minimize phone use throughout your day to prevent constant overheating.
If the solutions provided do not resolve the overheating issue, the logic board in your phone may be at fault. Since the logic board controls most parts of the phone, a broken piece of this logic board can indirectly cause overheating. To fix this problem, replace the logic board.
