The battery is one of the great mysteries of a smartphone. Just only we know her capacity measured in milliamp hours or WHr, and technology generally Lithium Ion (Li-Ion) and Lithium Polymer (Li-Poly). However, beyond these parameters, we can say little more than a battery.
Data such as real autonomy with mobile running, or the lifetime of the battery measured in cycles of loading and unloading, are an inexact science, much as manufacturers give us directions on how long you can be mobile playing video or surfing the Internet.
In real life, we are not only watching movies or surfing the Internet. We also use applications of all kinds, with an unpredictable effect on autonomy. Moreover, every smartphone has a kind of different, more or less powerful, with an effect on the battery charge it is not an exact science processor.
Autonomy, an inexact science
However, after a few days of use we can get a rough idea about the autonomy taking account of the time we loaded the smartphone a day. Or using apps like Battery Spy, which lets you create a record of the cycles of charge and discharge of the battery, as well as other parameters such as temperature.
In general, for a terminal with a battery between 2,000 mAh and 3,000 mAh, and a processor medium high or high range, with whom do photos often than usual is that we get to the end of the day rather rushed load.
If autonomy is a particularly valuable variable, some manufacturers offer terminals with a capacity greater than usual in cases like the ASUS ZenFone Max, reaches no less than 5,000 mAh, and which seeks to overcome exceeded the barrier of a day autonomy and even get two for use without excesses.
Charging cycles, myths and realities
The second parameter that defines a battery and at the same time, is another even more mysterious than the unknown autonomy is the number of cycles of charge and discharge it bears before losing a significant percentage of its nominal capacity.
This number of cycles will depend on aspects such as our habits when loading our smartphone in the day, or the care that we give to the battery. Without going any further, “scientific” figures speak of 300 to 500 charge cycles before the battery is significantly degraded.
With these figures, if we assume that we will charge the phone once a day, we will be spending one cycle per day, resulting in a time from year to year and a half before we start to notice that the battery “not hard”. Anyway, this figure is for full discharge cycles, as we move from 100% to 0% capacity to load up to 100% after.
If cycles are partial, which let only a portion of the battery discharge , the number of cycles increased to reach about 2000-2500 if recharge the battery when only downloaded 25% (when 75% capacity). If downloaded 50%, cycles become 1,200 to 1,500.
In practice, charging the battery when downloaded 50% gives us a little more leeway than if we hope to have a 0% battery. If we assume that spend all smartphone battery in one day, should do two partial daily loads, which means, for the best case, some 750 days before the battery is degraded significantly, compared to 500 the case better for full cycles.
With these 750 days, we have a respectable to amortize the use of our smartphone about two years time. Begin to notice that the battery does not last depend on each user, but eventually just happening. The battery is a chemical component, electronic, and is subject to an inevitable process of degradation of its components.
As a first summary, note that it’s okay to start charging the battery even if not fully discharged. Quite the contrary, is not good for the battery let it discharge completely.
It does not matter if you do not charge up to 100%. On the contrary, it is good practice to disconnect the smartphone charger when it has reached almost full capacity. The chargers are switched off when they detect a 100% charge to avoid damaging the battery, but if you do it physically, the better. On the other hand, it is important that the charger is the official or one that is prepared for it, all is said.
What can go wrong?
The calculation of load cycles earlier has been made under ideal conditions. But these conditions cannot always be. The less, we must take precautions so that everything goes as it should.
The first factor that may deviate from normal conditions is the temperature. The number one enemy of a battery is the heat. If a battery is heated, it breaks down to a much higher theoretical rate. And that translates into a reduction of capacity, which may be noticeable if the temperature remains high for a long time.
The temperature may rise, or because of the sun, or by related processes load causes. If we notice that the mobile is very hot while recharging, turn it off and disconnect the charger until cool. And then continued, but without turning on the terminal.
You can charge your smartphone while you are using, but if you do not want to take risks, and we can do without entailing a drawback, ideally charge mobile with it off. Thus, especially in devices with fast charging, the terminal can negotiate a precise times and voltages employed during the process.

If you are using the phone while recharging, it is more complicated for electronics calculate voltages and currents that need battery at a given time, which can lead to potential overheating.
By the way, the low temperatures are also a potential source of degradation for adversely affecting their chemical batteries. So do not think that cool the terminal in the fridge is a solution for warm-ups.
At the same time, as mentioned before, and ideally, although the smartphone stops charging when it reaches 100%, is disconnected from the power outlet when you have finished or earlier. Therefore, we avoid the risk that, for any reason unforeseen, the smartphone still receive power after reaching its peak. Something that seriously harm our device.
If we put a housing or a sheath, said housing remember to check that allows dissipating the heat generated by the smartphone correctly. If not, we will be contributing to overheating of the device, which is not at all recommended. Moreover, if you can get him out of the holster when it loads better.
As a second summary, we could focus on preventing the temperature of mobile in general and the particular battery rise above normal. A smartphone “burn” is not normal at all, either by the sun or during charging. If the phone is overheating, something is going wrong.
Very high capacity batteries: ASUS ZenFone Max
To solve the problem of shortage of battery or carry a powerbank always with us, or choose a terminal with high capacity. But what it is high?
ASUS has put the limit at 5,000 mAh of your model ZenFone Max. The approximately double the average in a format which, however, is just over 1 cm gross and 200 grams for its 5.5” screen.
The impact of this increased capacity is not only reflected in daily autonomy, but the usability of the terminal even when the battery begins to deteriorate after passing the corresponding limit cycles. A reduced capacity of 20% because of the use, the stay means ZenFone Max 4,000 mAh capacity, an amount greater than that of many new terminals.
The processor of this terminal is run by a Qualcomm Snapdragon 410, a choice in line with the philosophy of Max ZenFone that helps keep power consumption within optimum limits without involving having to give up a fluid performance.
Thus, the benefits of a high – capacity battery, transcend the dimension of autonomy to also achieve the protection of investment in mobile, power used for longer without that we begin to notice that the battery does not charge all that should.
It is especially interesting in the Unibody models where the battery cannot be replaced by the user as integrated into the terminal.
Another advantage of this mobile ASUS is the possibility of using the ZenFone Max as powerbank to charge other devices. The smartwatches, cameras and other “minor” peripherals can be loaded quickly without using a specially developed that take up space and add weight to the set powerbank.
The advantages of a large capacity battery are many and, despite the counterpart to add some extra thickness and weight, offer important advantages of face to make the most of the terminal.
