Let’s get rid of the old tips to extend the battery of the mobile

Before they had their raison d’être, but times change and batteries too.

The first mobile phone or cell phone was launched in 1973. Smartphones or smartphones began to be seen on the street from 2007, and since then many things have changed.

Each model surpasses the previous one in its touch screen, in the method used to unlock the screen, in the quantity and quality of integrated cameras, and of course they improve the storage, the speed of its processor and even the reception of wireless connections.

But an element that practically remains unchanged is the cell phone battery, whose technology is still similar between models. It is inevitable, then, that the battery life is the same or something less as each new smartphone that comes onto the market offers more and better features.
Technology and chemistry

To get an idea, both the first iPhone of 2007 and the umpteenth iPhone of 2018 use the same lithium ion technology in their batteries.

Both models provide a similar voltage: 3.7 volts on all models except the XS model, which goes up to 3.8. The difference is that the first iPhone offered 1,400 mAh while the iPhone XS reaches 2,658 mAh based on placing a larger battery.

But before the iPhone, mobile phones used other technology in their batteries, nickel cadmium (Ni-Cd), and some more recent models came to use their nickel-metal hydride substitute (Ni-MH), although it had little travel before the arrival of the lithium ion.

Nickel Cadmium batteries dominated the cell phone industry, and its peculiarities have led us to follow certain guidelines and advice on how to maintain or extend the life of the battery.

However, lithium ion batteries are the ones we currently use, and as they are different from the previous ones, the advice that we used to follow and still use some, is no longer useful.
The memory effect

The memory of the battery or memory effect is one of the most popular concepts for those of us who have had a mobile phone. On models with a Ni-Cd battery, it was recommended that your battery be depleted before charging it and fully charging it. It was also advised not to leave the charged phone plugged into the charger.

The reason was that if we made short charges, the battery lost capacity and its duration was reduced over time due to this memory effect.

Currently, lithium ion batteries lack memory effect. On the contrary, they work by load cycles, so you do not have to exhaust the battery or charge it 100%.

In current smartphones you can charge the battery when you think it is convenient and the time you think is necessary or available at that moment. With load cycles, the loss of capacity is minimal and the total capacity returns to 100% after a full load.

Another myth or obsolete advice was to make a full charge the first time we turned on the phone. Currently, phones are pre-loaded and this advice has no basis and utility.
Apple tips for current batteries

After reviewing the main tips that were used to lengthen the battery of the phone, let’s see what advice is given now.

Apple, for example, recommends the following:

Keep your software updated.
Avoid extreme temperatures, especially heat.
Remove the cover when charging to avoid excessive heating.
If you are not going to use it for a long time, save it at half load.

More tips, focused on iPhones and other smartphones:

Optimize settings, especially brightness and Wi-Fi.
Take advantage of the Low consumption mode.
Check the battery usage to see which apps and services consume the most.

Google tips for current batteries

To take care of and extend the capacity and duration of current batteries, Google recommends the following:

Use the official charger
Prevent the device from heating up.
Charge the device for the necessary time, no charges or full downloads
Savings settings, such as brightness, LED, vibration, etc.
Activate battery optimization.
Disable features that consume battery and do not need, such as Wi-Fi.
