How to choose the best portable battery charger for smartphone

Load capacity

The millimeter-hour (mAh) battery specification indicates the maximum amount of power your loads can receive. In this way, the higher these values, the greater the capacity of their loads. So the first thing to keep in mind before buying a portable battery is to see if the total values ??of your charge exceed the capacity indicated on the phone’s battery.

Battery power

It is important to choose a portable battery that has a power output power, indicated by the values ??specified in Watts (W), equal to or greater than the charging power of your smartphone.

If the electric current coming out of the portable battery is less than that needed to charge the gadget, the device will not charge. However, the higher the value of this current, the faster the battery can be recharged.

The service life

Remembering the power loss of the external battery when transferring your mAh amounts to smartphones, it is important that your users also evaluate their charge cycle. Also known as a useful life, this cycle can be calculated by comparing the mAh values ??of your portable battery capacity with the mAh indication on the device’s battery specifications.

Tips for increasing the battery life of your phone

  • Decrease screen brightness: The brightness of the screen is often responsible for more than half the power used in your phone. Phones with large screens like the Motorola Milestone have the screen as one of the major consumer villains. A very bright screen is only useful when using the phone in the sun outside. As such times are often rare, leave the screen brightness to a minimum.
  • Disable Bluetooh : Bluetooth is little used on devices compared to other wireless options. When you need to use Bluetooh, turn it on only on time and then hang up.
  • Turn off the keypad sounds: that noise when you press each key, if off, can contribute to your battery to last a few more minutes at the end of the day.

Turn off the wi-fi where there are no known networks: turn off the wi-fi. Otherwise the device will be running out of battery power by listing all the networks found wherever you are. This is even worse if I have been in transit, because as the signal from the networks becomes very variable, the phone ends up having to use more power to transmit the radio signals.

Turn off Wi-Fi where networks exist: If you need the phone to work longer before you can recharge it, you may want to leave the Wi-Fi (wireless network) turned off even at work or in places where there is a network without wire you can use. With Wi-Fi on, several programs are constantly exchanging information with the internet, which increases the consumption of the device.

  • Turn off automatic syncing: If you even need your phone on the internet, at least close non-essential programs. Programs and e-mail, Twitter and others constantly synchronize information with their servers. That eats a lot of drums!
  • Lock the screen or keyboard: especially when placing the device in a pocket or purse, lock the keyboard and the screen. If this is not done, the unit may be running out of power while the display is switched on and not in low power mode.
  • Use a darker theme: yes … this is a bit of paranoia, but in the Nokia N97 a white theme spent around 10% more battery than a black theme. I measured, believe me. In devices with LED screens and derivatives this difference is even greater. Use dark themes and fine print to “light” the smallest possible number of pixels on the screen. The battery lasts much longer.
