Nowadays people are moving around with cell phones, are not they? And sometimes the battery does not last all day … The best solution is to use a portable charger to ensure that your smartphone stays on even when there is no outlet nearby. But when it comes to choosing a charger, you have to do a lot of research so you do not risk ruining your phone, see!

You need to keep an eye on the charge capacity, which is measured in mAh. It shows whether or not the charger can fully charge the battery. It works like this: if the battery of the phone has a capacity of 3.000 mAh, the charger must have at least 3,000 mAh also to have a full charge. If the charger has 6,000 mAh, for example, then it can offer two full loads. Now, if the capacity is 1,500 mAh, then you can only charge 50% of the battery.

Another important detail is the power, which is measured in W [SPEAK WATTS]. Pro mobile if charged, it is necessary that the electric current coming out of the battery is greater or equal to the charging power of the smartphone, ok? If it is smaller, the cell phone will not charge! This mAh and W information is in the manual or in the box.

And to facilitate, look at this tip!

Portable batteries lose their useful life over time, meaning they lose performance and load capacity. To make the charger last longer, just recharge the device when the power is completely finished. Oh, and do not forget to turn off your cell phone when recharging so you do not waste battery power!

The Hard Bank has 2 models of chargers, the Power Bank AS 802 (pictured), which is designed to allow you to stay connected anywhere, with 6600 mHa, has a USB port 2.1A and 1A, which allows simultaneous charging of two devices and features an LED emergency flashlight.

10 Tips for Better Use of Your Mobile Phone Memory!

Since I had my first smartphone back in 2005/2006, my problems with memory of the handsets were constant. Just be the memory to run programs or the memory to store files, run out of space and even in cases where, suddenly, the cell phone hung out of nowhere, they were very common with me.

These problems continued to appear over time. Due to my disappointment, I restored the configuration of my phone to factory and loaded with applications again. It even worked, to the point where it slowed down again and I had to do the whole process again. That’s when I did not use the whole memory before.

Like what we already know, smartphones are found almost everywhere, and they range from basic models to the top of the line. As time goes by, they all slow down and the memory gradually gets busy. This is why you should keep your phone clean in both RAM and physical memory by following the simple tips.

  • Constant Updates

Update your phone software regularly. It fixes some bugs, firmwares and some lags. In some cases, it may even take up less space in the physical memory of your device.

  • Factory Settings

Make a backup of your entire device and return it to the factory settings. Performing this tip erases everything and brings your phone back to a new condition. Back up your contact lists and other important information before performing this tip.

  • Choose your apps well

Uninstall any unused applications. We often download several applications, but few actually use them. Delete some of these that you do not use as it helps to ease memory consumption.

  • Restart your phone

When the device experiences delays and slowness, restart it. Somehow, it helps, even being a temporary option.

  • Root on your device

Valid for devices with Android operating system. With root, you can uninstall the modifications made on Android by the operators and the useless programs that come in the set, optimizing not only the memory but the speed of your device.

  • Applications to optimize memories

In all application stores there are at least 10 programs to optimize the use of RAM and / or physical memory of your mobile device. Choose the ones with the best rating and optimize your device.

  • Organize your apps

Reduce the number of home screens by creating folders for your applications and leaving only the ones you use most frequently in view.

  • Monitor applications separately

Each application consumes an X amount of RAM and physical memory from your device. See which ones are taking up more space and make sure you can get rid of them.

  • Back up your music and photos

Send music and photos to your computer or an online storage service and be free of precious storage space on your device.

  • Buy a microSD card

You can buy a microSD card if your device has an entry, thus freeing up memory space on your smartphone. Remember to check the compatibility of your device before.

  • Bonus: buy a new cell phone

Did you do all of that and your cell phone is still slow or out of memory? So it’s time to buy a new cell phone to meet your new needs. Just be careful not to spend too much or mess up your resources.
