The current smartphone can boast of offering us an infinite number of features that make life easier for us every day, however, all of them have a great ballast in common, which is none other than the need to constantly recharge your battery. We have made tremendous progress in aspects such as higher power, better visualization, great connectivity and the use of extra large screens. However, energy consumption It is so wild that as a general rule one or more daily refills are necessary.
Your background technology
Most modern mobile devices use rechargeable lithium-ion batteries that consist of two main parts: a pair of electrodes and the electrolyte between them. The materials that these electrodes vary (can be of lithium, graphite or even nanowires), but all are based on lithium chemistry. It is a reactive metal, which means that it has a tendency to combine with other elements. Pure lithium It is so reactive that it can ignite in the air, so most batteries use a safer form called lithium oxide and cobalt. Between the two electrodes is the electrolyte, which is generally an organic liquid solvent that allows electrons to flow between them. When a lithium-ion battery is charged, the cobalt and lithium oxide molecules capture and retain the electrons, which are then released when the battery is in use, for example, when we call by phone. We see the tips.
Check the updates
Many of the applications, Widgets and wallpapers They rely on constant Internet connection to display updated information. We recommend that you review the periodicity with which each application is updated and adjust each one to your needs, limiting the use of data and the number of times that are updated per day. Deactivate the least consulted and set the least important for the update to be manual.
Communication and location services
It controls to a greater extent the use that the mobile makes of the wireless connections and activates them only when necessary. Not only the Wifi connection consume battery, but also connections between devices by Bluetooth, as well as positioning services by GPS. There are countless Apps that make excessive use of GPS in order to position yourself or facilitate route tracking, and the use of maps by GPS at street level it requires more battery.
Less voice inquiries
Both Siri on the iPhone, like any other voice assistant on Android or Windows Phone, use the data connection constantly to answer the questions we launch on the phone. It should be taken into account and at least used to a lesser extent when the battery charge is especially low.
We all like to visualize Retina or Super AMOLED Plus screens at its best, but it is convenient to set the brightness level of the screen in automatic mode. The latest operating system versions usually offer an estimate of consumption and the screen is the most devastating. Check the disconnection times and opt for passive wallpapers or wallpapers that in the long run consume less battery. In addition, the main operating systems of mobile phones (Android, iOS and Windows Phone), they offer quick access to the connectivity and brightness part of the screen, so that we can even set a lower illumination to the brightness of the automatic mode provided by the system. We will be able to extend the autonomy of the battery.
It is proven that the use of visual alerts instead of vibration allows to improve the autonomy. But above all, it deactivates the typical vibration that occurs on the screen as a result of pressing the keys. If you use often Whatsapp to communicate, improve mobile performance. Email in push-email mode may not be so decisive for you. Set it up only when strictly necessary. Similarly, use an application that offers you a centralized management of social networks in order not to have several applications open constantly.
Many of the terminals with Android Jelly Bean they already contemplate within the settings the battery saving function, so that when their level is below a certain percentage, the mobile displays its own settings to make it last longer. They also exist in Google Play and in the App Store applications specific ones that will help you improve values. Some manufacturers personalize mobile phones with software adapted for this purpose.
Eye with the wearables
The massive use of wearable devices, such as bands, pedometers or smart watches, is making it necessary to maintain the Bluetooth connectivity of the active phone to communicate with this type of devices. Sometimes it may not be necessary to have the signal active, because we have the smartphone. We can also set night hours where it is not necessary that the smartwatch and the smartphone They are communicated. Try to adopt measures that allow you to make excessive consumption of the battery. Although the last specification of Bluetooth 4.0 it hardly consumes energy, it is still another element of communication.
Down with the myths
Far has been the time when it was advisable to use up its load to be recharged. Nor is it necessary that the first charge be complete so that it does not affect its duration, a myth inherited from Nickel models. LThe current lithium ions present more energy density, which does not mean that they have a limited number of cycles, and over time, their original capacity will be reduced. Once exceeded 4 years of use its replacement should be considered. Meanwhile, perform at least one full charge cycle per month to keep it fit.
Lithium ions They are usually the most used in the battery because they can store more energy in the smallest space. That is measured based on the specific energy density, which refers to the amount of energy in watt-hours, which a kilo of the battery can hold. In lithium ions the figure can be between 150 and 250 Wh / Kg, while a battery of nickel and methyl hydride (NiMH) in the battery can contain around 100 Wh / Kg. In other words, lithium ion batteries They are smaller and lighter than the rest, and that means the devices can be smaller with a longer battery life.
The capacity of a battery is measured in milliampere-hour (mAh), which indicate how much power the battery can supply over time. For example, if the battery has a 1000 mAh rating, it could offer 1,000 milliamps of power for 1 hour. If the device uses 500 milliamps, the battery should last approximately 2 hours.
