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.

5 tips to increase the battery life of your mobile phone

The most current gadget is powered by lithium-ion . They are quite different from batteries used in older devices, such as nickel-cadmium , and some procedures that help extend the life of older batteries may have the opposite effect on newer technologies. See five tips for your cell phone’s battery not to leave you in the hand with little time to use.

If you are going to charge the phone at night, remove the
Most smartphones today are smart enough to stop powering the battery when the charge reaches 100% , so there’s no need to worry about that. But if you go to sleep with a cell phone in the socket, it’s a good idea to take off the hood: lithium-ion batteries are extremely sensitive to heat and the measurement can increase their life.

Do not store the battery empty.

An empty battery is unstable, and can cause serious injury if it is taken out of the drawer after one or two months of use. Ideally, you store your battery with about 40% of the charge . It tends to lose something between 5% and 10% of the energy stored each month spent in idleness, a security rate good enough to prevent explosions when it is put into the power outlet.

Do not let yourself beat 0% or 100% frequently

Modern batteries do not like extremes. Ideally, if possible, always carry it from 40% to 80%. A full recharge cycle is exhausting and the battery life is shortened.

Make small daily refills

Contrary to what most parents think, the lithium-ion batteries used in modern cell phones do not suffer from memory problems like their older relatives, those of nickel-cadmium. That is, they will not hook up at 80% if you do not have time to leave the phone in the socket until it reaches 100%. On the contrary, small daily recharges , which keep the level above half, help increase battery life.

Do not use the fast charge mode

Lithium-ion batteries are sensitive to heat and sudden variations in electrical voltage . They prefer everything to happen slowly and always. The fast charging option available on some Android devices , therefore, can even break a branch from time to time, but it is very harmful to the health of the device.
