Solar Mobile Phone Charger: How to Choose Yours?

-Weight and size: at first all chargers are portable, but it is good to know if it is really lightweight and does not take up too much space. If the size or weight is disproportionate, there is a great risk that you will abandon the use of the device.

-Price per power generation: It is very important to know the power capacity of the charger and to realize how much you are paying for it. This means that not always the cheapest charger will be the best option.

-The need for your device: Some phones and smartphones need more power than others. If the chosen charger is not able to deliver this power, the time to recharge may become unfeasible.

Nine tricks to make your phone’s battery last longer

Does your cell phone battery always end up when you need it most? And when there is no outlet close by to carry it? Does your portable charger ever let you down?
Despite some advancements, making a battery last longer is a challenge for the telephony industry.

While they are looking for solutions, we have put together a series of quick adjustments that you can make on your phone to make the battery pay more.

1. Adjust the screen brightness

The brightness of the display of your device has a great impact on the battery consumption. Decrease the brightness and keep it as low as possible in a way that is still comfortable to read.
To do this, go to Settings or settings >> Screen or brightness, depending on the type of mobile you have.
You can also turn off the “auto brightness” option, since it may be optimized to be at a very high brightness level.

2. Turn off vibrate mode

Letting the cellphone vibrate along with the beep or when in silent mode consumes a lot of battery power. It is a useful function for anyone who does not want the cell phone to ring. But if you do not need it, it’s best to turn it off. To do this, go to Settings and Adjustments, and then click Sound.

3. Reduce screen lock time

Much of a battery’s life is consumed with the use of the home screen. So, the less time your cell phone takes to darken the screen, the more it saves battery life.
To check this, go to Settings >> General >> Automatic lock. Then select the shortest possible time.

4. Disconnect wi-fi and bluetooth connections

Both functions undermine the battery of any cell phone. If you are not using it, turn off one or both.
Remember that there is no reason to walk around with the wi-fi connected. Both the new Android and iPhone models have options to turn both connections on or off on the home screen, so you do not have to go to the settings menu.

5. Disable the permanent GPS location

This is another of the battery-consuming functions. But you can turn it off or restrict its use.
To do this, go to Settings >> Privacy >> Location. On this screen, you can either disable the feature entirely or, depending on your phone, select the apps that can use the location service.

6. Reduce notifications

Do you even have to know at the time each time someone likes or comments a post on Facebook? If you feel it is not critical in your life, consider turning off notifications from your social networks.

Keep in mind that notifications light up the screen and thus spend battery power.

To do this, go to Settings or Settings >> Notifications >> and adjust your preference for each application.

7. Do not let applications run “in the background”

If enabled, this feature allows applications to be updated when your phone is connected to a Wi-Fi network, for example.
But to save energy, it’s worth to disable this feature entirely, or at least for applications that do not always have to be updated.

To change, go to Configuration >> General >> update “in the background”

It is also worth remembering to close the applications when you are no longer using them.

8. Check which of your applications are consuming more battery power

In both Android and iPhone it is possible to check the percentage of battery used by applications like Whatsapp, Facebook and Skype.

Thus, it is easier to decide whether it is worth leaving them open or closed.

On the iPhone, go to Settings >> General >> Usage >> Battery usage. On Android, the path is Settings >> Battery management >> Battery usage.

9. If you have an Android, turn on the power save mode
You can activate this function to extend battery life when convenient.

To do this, go to Settings >> Battery Management. In some models, you can choose up to three different types of economy, which combine various tricks cited in this text.
