SECRETS of HOW to make the BATTERY of your cell PHONE LAST LONGER

What you need to know to choose the right portable battery 

The differences between each product, including battery capacity, power ports and physical size, are usually the main items to consider when choosing.

In addition, as also happens with cell phones, portable batteries have a finite life cycle.

A good estimate of its actual capacity is to approximate it to

60-70% of its theoretical capacity.

batteries implement

an intelligent system that distributes it.

The charging speed is another important piece of information, but not only when it comes to charging a phone, but also for the battery itself.
