Batteries are undoubtedly one of the most important parts of our smartphones. What is a large RAM, huge internal memory or an eight-core processor, when the battery runs out unexpectedly? Their charging and stamina circulating a series of myths and half-truths. Let us, therefore, some of them look.
A number of myths about charging the batteries of mobile phones is due to technological progress - simply put, what was true for older types of batteries for new ones already do not pay. Users, however, difficult to forget something for them for many years a daily necessity.
The first type of batteries that use mobile phones, the nickel-cadmium (Ni-Cd) batteries. On the one hand, these batteries have been very effective because they reached a large number of charge cycles, on the other hand, however, were susceptible to temperature fluctuations and suffered a gradual discharge. Successor Ni-Cd was nickel-metal hydride battery (Ni-MH). The advantage over the previous model was larger battery capacity, even though this kind of suffered from self-discharge, although less so than its predecessor.
Batteries containing nickel gradually replaced with lithium batteries. These are divided into two types - Lithium-Ion (Li-Ion) and more modern lithium-polymer (Li-Pol). These batteries suffer from no effect of self-discharge, as its two predecessors, and greatly prolong their life as well. For Li-Ion battery is about 40% increase in Li-Pol, then even more. In both cases, these so-called smart batteries, which have built-in sensors guarding the charging process.
One of the traditional myths concerns, new batteries and putting them into operation. Many of those who have experience with mobile phones since the days of indestructible Nokia 3310, will tell you that need a new battery a few times to fully discharge and then recharge to full. This was true for batteries containing nickel, which is at its maximum capacity reached after three to five such cycles. Cycle means just battery to 0% capacity and its subsequent recharge to 100%.
"Li-Ion and Li-Pol batteries have such an initiation process required. The first time you use it but should fully charge the battery, then disconnect from the charger, let rest for about an hour and then again for a moment to connect to the charger. This ensures maximum battery charge, "Radio Tlapak (BatteryShop.cz).
Another of the myths regarding the time recharging the battery. According to him, it is best to keep the battery if possible nearly discharged and subsequently charged to its maximum capacity. The origins of this frequent error can be traced back to the Ni-Cd and Ni-MH batteries. They in fact directly demanded that nabíjel If possible, always full, or else threatened loss of capacity.
Modern Li-Ion and Li-Pol batteries have this bad habit but do not suffer from a discharging and charging into one hundred percent capacity even their assertion. The more complete cycles because lithium battery undergoes, the closer it is to the moment when they will not deploy. It is ideal phone during the day repeatedly recharged and hold the battery capacity of about 20 to 90 percent. Each full charge in fact reduces the battery life on a single cycle. Good condition of the battery is up to 500 charge cycles, then begin its properties deteriorate significantly.
Li-Ion and Li-Pol are called smart batteries. Although their charge to its maximum capacity usually just two to three hours, network connectivity throughout the night bother them too - alone stops charging once they reach one hundred percent. Even though it is a myth partly true. As has already been said, new types of batteries to full charge no evidence too, so if you want to make the most of their lifespan extended, charge them better through the day and more often.
With the new batteries do not really understand, the high temperatures. "Slight heating of the article during charging is normal. We should, however, refrain from actions that could further increase the temperature. It is therefore not suitable, for example putting the phone under the pillow at night - whether charged or not - or during hot summer for the car window. When charging is also putting out a good phone from the bag, which itself does not levy the heat too well, "explains Radim Tlapak.
Batteries of mobile phones does not indicate any opposite extreme. One of the dangerous treacherous councils, which from time to time on the internet, is to put the outgoing battery in a plastic bag in the freezer. You do not even try, straight reveal that this method leads to the destruction of the battery.
