Today we will learn some tricks and tips by using which we can save our phone’s charge back up and keep the device on for longer than the average. Sometimes when we are in an emergency and we don’t get time to charge the phone at all then these tricks could be life-saving. Nowadays few mobile manufacturers provide a feature named ULTRA POWER SAVING MODE, and by using this feature phone can actually last longer than the average, but for the devices which don’t have this specification, we’ll modify those and create an efficient output out of them.

Trick-1: Checking all your connectivity such as Bluetooth, GPS & WiFi. Usually, GPS draws a lot of power as it has to send/receive the signal from the satellite and keep the devices connected with the positioning system. When you don’t need those connectivity to stay on then you can turn those features off and find surprising results afterward.

Trick-2: Turning off the data connection (if not necessary). Usually, when we use higher/faster data mode such as 3G/4G/5G then the device draws much more power than the usual time. So, if you’re not using the data at all or if you don’t need to be connected to the internet then you may turn off the data mode completely and save a significant amount of charge.

Trick-3: Reducing the display brightness. Though nowadays displays technologies are so power efficient such as OLED(Organic Light Emitting Diode), AMOLED(Active Matrix Organic Light Emitting Diode), sAMOLED(Super-Active Matrix Organic Light Emitting Diode), or Fluid AMOLED(Active Matrix Organic Light Emitting Diode) panels. And reducing display brightness means the light source has to deliver lower light intensity which leads to using less power, so it would work perfectly fine in order to save energy. In a Purdue study, it has been mentioned that dark mode uses less power than light mode one. So, if you have the accessibility to turn on the dark mode it may help a bit as well.

Trick-4: Another thing is the Refresh Rate (Hz) of the display. If you're running at 90Hz/120Hz/144Hz on the mobile devices then you may turn that settings off or reduce it to a lower minimum standard which is 60Hz. It'll surprisingly save a lot of your phone battery's energy.

Trick-5: Mobile network mode is another power-consuming factor. Power draw depends on the mobile network. i.e.: mobile networks such as 2G/3G/4G/5G. Power draws changes depending on the type of mobile network. So, if you’re connected to 3G/4G/5G mobile network and you need to keep your phone standby for an extended time then switch your mobile device network mode from 3G/4G/5G to 2G Mode. It’ll let you keep your phone stays for longer than the average.

Trick-6: If you’re roaming (driving or moving spontaneously) from one place to another then the phone’s network chip work harder than usual to keep the devices connected with a cellular zone, which means draws more power and drains the battery faster than the usual. Or if you don’t need to keep your phone connected to the network coverage, then simply use the AIRPLANE/FIGHT MODE from the control bar to turn off the network connectivity of the phone. Using this feature you can also keep your phone stay much longer than the usual time.  It’ll then only stay as a standby device and use less energy, which will increase battery back-up.

Conclusion: So, I hope these tricks & tips will help you to keep the devices awake for longer than you expected and maybe life-saving hacks. If you have any other question regarding any of the mentioned items feel free to mention in the comment section.
