Though not specifically for Yuphoria, but one can observe a few methods to control overheating of the smartphones.
Actually, smartphones these days use better processors needing higher energy and thus generate heat. No proper attention is paid to proper ventilation in a bid to make the phone thinner. Use following methods and see it it helps -
Disable unwanted functions
Keep a tab on the apps and processes that need more energy. Enable them only when needed. Using apps like Greenify may be helpful here as it can keep a tab on background activities of the selected apps.
Limit the time for resource intensive tasks
Resource intensive tasks like browsing for longer periods of time can consume much energy. Thus in turn releases more heat.Even gaming for long durations can generate more heat. Limit the time spent on such apps.
Use genuine batteries
Using third party substandard batteries can result in heavy heat generation. Try not to fall prey to the low priced batteries available on ecommerce sites. If you have to buy a third party battery, go for reputed names like Mugen or Anker .
Take precautions while charging
Though it may appear silly, improper charging process can result in abnormal Heat generation. Always use original chargers. Keep the place of charging well ventilated.
A few more tips
