The battery of any phone sooner or later loses its original performance and wears out. And if the outdated phone models can hold a charge for a long time, then modern smartphones are capable of more by default and support many functions and applications that "drain" the battery pretty quickly. Is it possible to prevent rapid deterioration of the battery and prolong the period of its use?

How to check the phone's battery

  It's not at all necessary to be a professional to determine what's wrong with the phone's battery. Most problems can easily be identified with the naked eye, in particular this applies to lithium batteries (the most common type). One way to test the performance of a mobile phone battery is a visual inspection of the part. Turn off the device, remove the battery and check if it is swollen, if there are signs of corrosion around the metal contact elements (whitish or green spots from the oxidation of the metal). If you find even the slightest sign of a physical malfunction, you should immediately contact the manufacturer for replacement (if the warranty period has not expired) or purchase a new battery. Under no circumstances should you put such a damaged battery back in the phone, hoping that it will last a little longer - inside the device electrolyte may spill and irretrievably damage it. Put the battery in a plastic bag, send it to the manufacturer or take it for recycling. Lithium batteries inevitably degrade, and the incorrect use of the device only speeds up this process (sudden changes in temperature, humidity, pressure, etc.). The most effective way to once and for all "plant" the battery is to completely discharge it and leave it in that state for a few days. The body will gradually and unnoticed for the eye to swell and deform until it becomes obvious. But there is one way to prevent breakage - put the battery on a flat smooth surface and twist, as if launching a whirligig. If it is easy and fast to scroll, then the body has already begun to deteriorate.

Recover phone battery

  If the battery is quickly discharged, but there are no visible damages, it can be "resuscitated" by several unusual methods. In this article we will consider only the simplest of the many ways that you can use at home without special skills and tools. How to restore the battery:

1. Place the battery in a plastic bag and place for a while in the freezer. Low temperature will help to restore the fuse, the malfunction of which leads to a rapid charge.
2. Lower the battery voltage of the mobile to 1 Volt.
3. Allow the battery to fully discharge so that the phone turns itself off, and then charge up to 100%. Repeat the procedure 3-4 times.
4. "Resurrect" the battery helps not only cold, but also high temperature. It is necessary to give the battery fully discharged and put it on a hot battery, laying a cotton shawl. Leave to warm for at least 3 hours (best - all night), put on charge, not including the phone, for 24 hours, then use it in normal mode.

If none of the above methods has helped, you should contact a specialist for assistance or purchase a new battery. In any case, do not open the battery, knock it on a hard surface or bite it with your teeth - a popular popular way to "revive" a normal battery in this case does not work and can cause harm to health and finally spoil the part.

The development of AccuBattery began after a small team of Dutch engineers was puzzled by how to extend the life of the battery. No, do not slow down the discharge during the day, but make sure that the battery does not lose its capacity after long months of constant operation. The problem is especially urgent in the light of the fact that many modern smartphones are supplied with non-removable power supplies.

In search of a response, the developers conducted series of tests  and received a couple important conclusions. First, charging the phone throughout the night is a very bad habit, which, unfortunately, is common to most.

According to the researchers, the battery loses its capacity at overloads. The reason for this is the chemical processes taking place in the battery. Although all smartphones have an internal switch that stops charging when reaching 100%, the power continues to ooze, which affects the resistance to oxidation of certain chemicals. Thus, if you still need a full "tank", you should disconnect the phone from the electrical outlet as soon as possible after it is charged 100%.

Secondly, it is better to charge the battery up to 80%. So the term of its service can be increased at once in two, and even in four times. In this connection, AccuBattery has an built-in "alarm clock", which provides active signals when the optimal level of charge is reached. It is located in the section "Charging".

At the top of the window is a circle, the green part of which shows the current percentage of charge, and the blue one - acceptable. The default setting is 80%, but it can be increased or decreased. Move the slider and notice how this affected the damage to the battery.

A little further is the forecast for the discharge of the battery with mixed use, as well as the on and off screen. Estimates are based on your habits when working with a smartphone for the past seven days.

Finally, scroll even lower and find out how quickly your gadget is charging from different power sources. For example, connect the "native" charging, turn off the smartphone for a couple of minutes, and then look in the Charge speed block. It gives exact data on how much time is left before the optimal charge. Repeat the steps with another charger or external battery to compare the speed.

This section provides statistics on the battery consumption since the last charge. Go to the "Battery usage" section, where you can see the following information in sequence:

• How much percent is spent when the screen is on or off and for how long.
• Which applications have spent the most amount of ampere-hours (mAh).
• How long the phone was in sleep mode and how often it was interrupted.

Next, you can see the list of applications that have actively used the battery. AccuBattery authors emphasize that their measurement method is more accurate than the one used by the Android system itself.

Sections "Health" and "History"

The section "Health" is a source of pride for the creators of AccuBattery. When connected to a power source, the application monitors how much power is supplied to the battery and what percentage of full charge it makes. Based on the obtained data, the estimated residual capacity is calculated. To more accurately determine the current capacity, several long charging cycles are necessary.

Comparing the nominal capacity of the battery with the remaining one, you can find out how much it decreased during use. In addition to this, you will be presented with two graphs: the first shows wear for each day of operation, and on the second - the level of real capacity as a percentage of the factory capacity.

The "History" section stores information about each charge and discharge. Touch any of them to see the details if the general information is not enough.

Conclusion

AccuBattery - a new application on Google Play, so it is not without a pair of annoying flaws. For example, you can not switch between screens by simply scrolling and you can not remove the application from the notification panel.

At the same time, AccuBattery perfectly copes with the duties assigned to it: it helps to pick up the fastest charge, calculate the most energy-intensive applications and find out how much less the battery has become during operation.

When the mobile phone battery starts to run down quickly, it becomes necessary to check its performance. This situation is possible in the case when it is required to install a high-capacity battery on super-productive mobile phones of the latest developments. So, check the phone's battery.

  What we need

Mobile phone (here - for example Samsung Galaxy Note);
- a new amplified battery for Samsung Galaxy Note smartphone (production of Hong Kong);
  - battery used before replacement;
- necessary software.

  Operating procedure

1.Download from PlayMarket "a the following programs:
- Battery Drain, collecting statistics on battery usage (percent / hours), with which you can determine hourly battery consumption;
- Battery Dr.Saver, allowing to carry out full charging AB and to measure the time spent on full charging;
- Battery HD, which performs battery calibration and shows approximate figures of its use;
- Battery Monitor Widget, a complex application in which all the above functions are combined.
2. We will test the phone with a new reinforced battery in comparison with the previously used formats   and . The test results are as follows:
- standardtesting (usual use of the phone - connected Wi-Fi and 3G, music about 1 hour, half an hour for games, 2 monitoring systems, web surfing for 1 hour) showed battery consumption about 4-6% per hour:

Thus, the power increase almost doubled.
- amplified(to the load used in standard testing, added Bluetooth and GPS, video camera, photography included) showed an increase in battery consumption up to 12-14% per hour:

The capacities of the reinforced battery were even greater.
- with   the maximum possible load  the battery consumption increased to 21-42% per hour:

The extreme load showed that the original battery could only work 3-4 hours, and reinforced -   up to 8 hours.
Checking the performance of the new battery in comparison with used earlier revealed its positive and negative sides:
- the weight and functionality of the phone have changed little;
- significantly increased the time of work, which is a big "plus";
- increasing the thickness of the smartphone almost does not affect the usability of its use.

Methods for testing the battery capacity of the phone

As you know, the larger the lithium battery made charge-discharge cycles, the stronger its degradation. It should be said that this is a natural process that does not depend on the cost of the gadget, functional and model. Li-Ion and LiPol batteries, which are used in modern telephones, are calculated for approximately 500 cycles. After that, they lose about half their original capacity. As a result, their service life is 2-3 years. How to determine that the battery should be changed? To understand this, you need to know. Let's see how this is done.

Battery capacity of the phone

This value expresses the ability of a battery to accumulate and give off electrical energy. The capacity is measured in ampere hours or watt-hours. What does this value mean for the user? First of all, this is the time that the battery can feed the phone. Suppose a battery with a capacity of 1700 mAh can provide 1,700 hours of current 1 mA.

That is, it is equal to the product of the time by the discharge current or charging current.

How to evaluate the battery status?

First, inspect the battery. If there are serious problems with the battery, then you will notice this in its appearance. As a result of prolonged active use, lithium batteries can swell. In addition, corrosion occurs on the contact areas. It is expressed in green and whitish traces.

If there is a distortion of the battery case, you need to replace it. Use such a battery only if absolutely necessary. There were times when electrolyte flowed out of the case and closed the microcircuits. This is a guaranteed battery outage. This is how the problem with the battery turns into large-scale problems with the phone. And bloating can not be detected immediately. First there is a small swelling and begins to expand.

In addition, another symptom of the rapid death of a battery is its rapid discharge. Typically, the average smartphone works offline for 3 days. If the battery is worn out, then this time decreases to 1 day or less. If this is your case, then take a closer look at the cell phone battery.

You can also note one more detail. If the battery life comes to an end, the charge can abnormally quickly end. For example, the indicator shows 30%. And then after a short telephone call he drops to 0.

Software for testing the capacity

In order to check the capacity, you can use some utilities for the phone. For example, for the iPhone and other gadgets running Apple there is a utility iBackupBot.

For devices running Android you can use the Battery program. It shows data such as battery status, temperature, voltage, etc. The application can be downloaded on GooglePlay.

Now you know how to check the capacity of your phone's battery and understand when a replacement is required. Successful operation of your devices!
