10 tips for optimizing mobile device autonomy and charging

There’s nothing more annoying than running out of battery without access to a charging point. Here are 10 tips for optimizing mobile device charging and autonomy.

1- Free all night

Do not leave your smartphone, computer, or tablet unattended while charging. All nightIn fact, once charged, the device continues to go through charge and discharge cycles, shortening battery life. So it’s a good idea to charge it as soon as you get home so you can unplug it before bed.

Some smartphones have interesting features. Optimized nightly rateIt limits charging to 80% of the battery and stops when it reaches this level, thus avoiding unnecessary charging cycles. Launched by Oppo, the technology is also found in OnePlus and Realme smartphones.

2- Use airplane mode

Airplane mode disables wifi, GPS, and Bluetooth, as well as phone networks and mobile data (4G and 5G). This mode is named after it was originally used to disconnect all connections while traveling by air.

But airplane mode is just as practical on dry land. It can be fully active when you don’t want to be disturbed during a meeting or when you want to have a quiet moment without being disturbed by ringtones and notifications.

Activating airplane mode also has the advantage of increasing autonomy mechanically by reducing the consumption caused by incoming and outgoing connections as well as notifications. Don’t be afraid to be active, especially at night.

3- Prefer mains charging

as much as possible prefer to charge on the mains Charge your smartphone or tablet via the USB port. The voltage supplied by these sockets is much lower than that supplied by outlets, making them very practical while on the move. Charging over a USB port is slower. If your device was shipped with a USB charging cable only, adapters are available on the market. USB/power universal and cheap.

However, if this is the case, we recommend the charger that came with your smartphone whenever possible. It is actually optimized for the model and allows for perfectly matched loads. This is especially true for recent models with fast charging capabilities.

4- full discharge after update

Leave your tablet or smartphone alone after updating the operating system full discharge Before charging, check the battery level indicator reset, there is a risk of introducing a non-negligible margin of error. This can be done every three months without major updates.

5- Adjust the screen

Screen power is the most consuming item on your device. So getting it right is very beneficial.

  • At first Disable automatic brightness adjustment, often too expensive. You can access it in settings. This adjustment should be made according to personal visual comfort. We also find that it is often achieved at a lower luminance than the default setting. This can be done not only on smartphones, but also on computers and tablets.
  • Another way to explore is wallpaper : Prohibit dynamic wallpapers. Beautiful, but very energy intensiveTherefore, prefer still images that are not very resource intensive and use dark colors if possible.
  • You can also adjust stand by at a minimum. Is it really convenient to keep your smartphone screen in your pocket and the stuff on your computer should be left on for two hours when not in use?
  • High-end smartphones often screen refresh rate 120 Hz. This allows you to enjoy perfect smoothness, especially in videos, but also in games. Problem, higher refresh rate means more consumption. The LTPO type screen adjusts the frequency in real time according to usage. If this is not the case for smartphones, lowering the frequency to 90 or 60 Hz in the display settings will have a positive impact on consumption and therefore autonomy. For example, you can manually change the frequency whenever you want to play.


6- Enable energy saving function

For smartphones and tablets, Energy saving function, do not hesitate to activate. In addition to optimizing screen consumption, it also allows processor consumption to be adapted to its use. In fact, processors are used more or less depending on what they are used for. For example, we watch HD videos more often than we send SMS, and our consumption depends on this activity.

Based on this observation, computer manufacturers have decided to integrate two graphics cards into some devices. One is a smaller card for general use and the other is a more powerful card dedicated to more intensive use of graphics resources.

Even without going that far, smartphones and touch tablets have energy saving modes that disable all unnecessary features. You may also be able to select the battery level that triggers energy saving mode.

7- Know how to manage energy-hungry apps

avoid increase the application Things that update regularly, such as social networks and message notifications. They periodically initiate very high consumption requests. Also, as much as possible, especially at home, prefer wifi Moving to 4G or 5G not only saves data packages, but also because it consumes less power.

Similarly, 4G and 5G are not always needed for phones, 3G or 2G are sufficient for this application. So you can set your smartphone to prioritize this non-greedy network connection. Finally the consumption king is his GPS mode.so use If you don’t use it, don’t hesitate to deactivate it.


8- Watch out for dirt!

on your smartphone or in your settings Tabletyou have access to active appYou’d be surprised how many of them keep running in the background even though they’re closed. Don’t hesitate to go there and manually close the defiant one.

You can also clean up unused apps. In addition to the fact that this frees up storage space, it allows you to avoid unnecessary resource-consuming applications, i.e. battery-hungry applications that launch at boot time. You can check if there is a “Pause activity when unused” option in the settings.

9- Stop vibrating!

very practical and vibration notification hungry for energy. So you have to choose between comfort and battery saving.

10- Stop the cold

cold and charging should not be mixed. For efficiency, choose the warmest room in your home to charge your device. On the other hand, if not used for a long period of time, the battery will discharge less in a cold environment than in a warm environment. don’t put it in the fridge…
