This includes your calendar, weather app, Social media apps, and much more. If you want to keep yourself updated then it is recommended that your Wi-Fi should always be turned on.
The majority of people are not aware of what the “Keep Wi-Fi on during sleep” feature does in their smartphones. To save battery smartphones go into sleep mode when they’re not being used. This causes a lot of apps that were operating in the background to stop. If you have disabled the “keep Wi-Fi on during sleep” feature on your phone then your Wi-Fi will disconnect from your smartphone as soon as it goes to sleep.
This can cause the apps that rely on a constant Wi-Fi connection to stop working until the Wi-Fi is turned back on. This may include your Gmail app which won’t show you updated mail. It will also cause any downloading\uploading you were doing.
