If your phone is constantly searching for a Wi-Fi signal on your commute, as you run errands, or when you’re out with friends, it can easily burn through a lot of power. If you want to save your battery then turn off Wi-Fi to prevent your phone from searching for a signal you won’t use. It will save some extra battery life.
If you rarely use your phone for GPS, you probably don’t need your phone to constantly ping satellites for a service that you’re not using anyway. So keep your GPS off if you do not need it. If your GPS is enabled, then your mobile phone is always going to be trying to connect to a network and it is one of the most battery-intensive tasks your phone does.
The biggest cause of excessive battery drain on smartphones are the apps in the background. If you see the list even today, you see a ton of well known culprits. Apps like Vine or Candy Crush Saga, as well as the Social Media applications refreshing automatically in the background cause a lot of drain. So you should manually off those apps running in the background.
Apps are really sold on push notifications in order to re-engage with their users. Especially e-commerce and social media apps are serial offenders here. If you have these apps, do disable their push notifications. Some of these apps send about two to three notifications a day and that causes your phone to drain your battery soon. Enabling a DND mode also is a quick solution to overcome this problem.
Everyone keeps their cellphones on a vibrate mode so that you should get that your phone is ringing as well as people around you should not get disturbed but the sad truth is that a gentle buzz drains your battery much faster than a ring or, of course, silent mode.
If you like some great live wallpaper and you are keeping it on your phone then you are definitely coughing away much needed battery. Using black or deep coloured background is a good way to preserve battery. The sharper the contrast and more vivid the colours, more battery is likely to be drained.
Another reason of a battery drain is enabling automatic syncing in an assortment of apps. Automatically backing up your photos or syncing your apps and data sounds like a good idea but it consumes your phone battery consistently which results into a dying of a battery.
