Jumps (Jumps) The Percentage Of Battery Power On The Iphone

The world was flooded with armies of mobile equipment, each person has a smartphone or at least an ordinary “dialer”, so it is not surprising that the number of calls to service centers for repairing cell phones is only growing. One of the popular topics of appeal. battery failure or why the phone is not fully charged. Not only owners of smartphones, but also ordinary cell phones suffer from this problem. The technologies in the battery are the same, so the solution will be universal and suitable for any device. Getting down.

First, a little theory about batteries and how they work. There is no difference between a battery or a battery; the principle of operation is the same for everyone. energy is generated due to the potential difference that arises between metal plates in a liquid or gel electrolyte solution. The principle of action has been known for a long time, a couple of centuries for sure.

Modern telephone batteries operate on exactly the same principle. The only thing, the materials and manufacturing methods have changed a lot, now lithium metal, cobalt and carbon salts are used. Li-ion batteries, unlike NiCd, do not have a memory effect, they can be charged at any degree of discharge. Many manufacturers declare a warranty period of use, without loss of capacity, more than 300 full cycles.

Not surprisingly, the NiCd battery does not get to the end and does not work at full power. The same problem occurs with Li-Ion, but these are rather exceptions to the rules and in most cases, the capacity can be restored to the initial one. This explains why the phone’s battery sometimes does not fully charge.

There is a strong opinion among smartphone users that the new, just-bought Li-Ion battery needs to be “rocked”. You do not need to do this, although there will not be much harm from this action, but at least there is no benefit. It is better not to discharge the battery below 40% and not to exceed 80% of the full capacity when charging. In this case, the battery will last not just long, but for a very long time, going far beyond the required 300-400 full cycles. In some models of batteries, controllers are built in to limit the charge to these values, but they are rare and too expensive for ordinary consumers.

It is worth remembering that at temperatures below 0 and above 45 degrees, the iPhone battery will not be able to charge more than 1 percent, since this goes beyond performance.

Protect the battery from overheating and from frost, only in this case it will last a long time and we will not lose capacity.

Causes

Now we are moving smoothly from theory to practice, we will examine why the Li-Ion battery does not fully charge at normal temperature on a cell phone. There are several main reasons; here is a list of the main problems:

  1. Perhaps the memory is broken or burned out, for a start we will check it.
  2. The temperature regime is not observed, for Li-Ion battery requires a temperature of 2-3 degrees to 45 degrees Celsius, otherwise, the question will arise, why the phone refuses to take charge and does not charge to the end.
  3. Broken or kinked charging cable.
  4. The hardware is not cable and smartphone compatible or using non-native charging
  5. The charging connector on the smartphone is broken or clogged.
  6. The battery is dead.
  7. Blown power controller or problem in another board;

If you find a familiar problem here, then you could find the answer to the question why your phone does not charge to the required 100 percent. How to fix and what to do, we read in the next section, but for now we’ll see a useful video on the topic.

Poor or incomplete energy

As already mentioned, it is necessary to check the cable for damage and kinks, one broken core in the cord is enough for the phone to charge for a long time and not reach 100 percent. What to do in this case, the layman asks? It’s simple, we take the cord and the power adapter (unit with USB output) from another phone, and try to charge it.

If after 2-3 hours the battery is full, then it was the wire, and it’s worth finding a replacement. If the energy in the battery is only 10-40 percent, then we continue to search for the cause of the breakdown.

We comply with the temperature regime

Now let’s pay attention to ambient temperatures. If you want to charge your Samsung or iPhone on the street at minus 10 degrees, it’s better to leave your idea, nothing good will come of it. The operating temperature of Li-Ion batteries is from 2-3 degrees to 45 degrees Celsius. When you leave this range, the smartphone will not charge up to 100%, no matter how you try.

Another example, leave an iPhone or Samsung smartphone on the dash of a car in the summer heat. After 2 hours of being in the sun, the device will refuse to not only charge the battery, but simply turn on. The gadget damage prevention system will work. Therefore, you should not ask yourself “why my phone does not charge well and does not charge fully in the summer heat in the sun”. The answer is obvious.

Using quality accessories

Users are often worried: is it possible to charge your phone with an original or non-native charge. Yes, you can, only carefully.

It is worthwhile to carefully approach the selection of accessories for your equipment, do not chase cheapness, it can come out sideways. For example, a power controller may burn out, which will have to be re-soldered, which is expensive. Or even damage the battery, as it will be charged with inappropriate voltage for a long time.

Original accessories are still preferable, they are already configured for the current and voltage needed by the smartphone, there will not be problems with such an adapter. Monitor the quality of wires and power adapters and then the smartphone and battery will live in it for a long time and will please the owner with a great battery life.

Another reason why the phone does not charge well and / or does not fully charge may be a software problem. For the android platform, viruses are known that can interfere with all system processes, including interfering with the full charge of the battery.

To exclude this probability, if there is a problem with the battery, it is enough to reset the smartphone to the factory settings. How to do this is written in the articles:

  1. Reset to factory settings for Android devices
  2. Reset to factory settings for iPhone

There is a high probability that this will help, if not, read on

Hardware problems

They tried everything, but nothing helps in your situation, the question "why does not this charge … the phone to the end" is still relevant? Then it remains to contact the repair technicians of mobile equipment, problems can hardly be solved with one’s own hands. Most likely the battery itself was covered, on some Samsung models you can try to change it yourself, but on the iPhone it doesn’t work out, you have to open the device’s case. Which is categorically not recommended for people who do not have special knowledge.

Summarize

In this article, we tried to answer the hackneyed question: why a cell phone is not fully charged, we have sorted out many controversial issues and listed solutions to the dilemma.

  1. Use original cables and power adapters
  2. Watch the temperature of the device
  3. Do not try to repair the battery yourself. contact the service center if nothing helps.

The trouble with many cheap Android tablets is battery glitch. When working from the network, everything is fine, and when you turn off and start the application – the tablet goes dead. How so? After all, he just showed 100% charge! Another symptom is often noted: without connecting the charging indicator shows 100%, and when connected – 99%. This case can safely be called a “freezing battery indicator”.

How to be The easiest way is to try to fully discharge the battery and fully charge it. It is recommended to charge using a charger, rather than a USB cord.

But this method may not work. Therefore, they offer a second way – to get superuser rights, root, and by tricky manipulations with pulling / pulling out the battery and deleting the file data / system / batterystats.bin reach resetting battery counter. There is no desire to disassemble the gadget, it’s not your smartphone, and deleting the file, they say, makes no sense, because it just collects statistics on how many of the applications ate the batteries. It is possible that the battery is generally soldered (on Chinese tablets this is a common thing).

But there is a third way. It also requires root, but it is not necessary to disassemble the gadget. So, step by step instructions, tested on yourself. The way, as I understand it, is universal enough, at least for the fourth android (I did not go too far into the specifications). For those who are afraid of losing the guarantee and that the gadget will die, I want to say right away – close this page and bring your animal to a service center. Wimps don’t belong here.

1. If you have root rights, go to step 2. I recommend looking for how to get root on your gadget so as not to get into trouble. I used a universal tool – download (if you did not find another way) here this file Without unpacking, drop it onto the SD-card, which we insert into a disconnected tablet. Simultaneously pressing the power and lowering volume (and holding them) we will get into the recovery menu of Android. In this menu, you can try to return to the factory settings, but personally it did not help me (as well as updating the firmware). We need an item apply update from sdcard. Navigation through the menu is very simple – the transitions through the items are done by pressing the volume keys, and the selection is done with the shutdown button. We select the item that I spoke about earlier, go into it and see our archive. In the same way, select it and wait until Android becomes supple. After the system boots up, you will see Root Explorer in the list of applications. We do not need it, but this is a sign)

2. So, we are root and we need a terminal to enter commands. For these purposes, I set Android Terminal Emulator Discharge the tablet to the very minimum (although, with the indicator freezing, this is already done).

3. Run the terminal and execute four commands. After each press Enter (you know how to use the command line, right?)

If the charge level is not displayed correctly, the smartphone itself turns off and other battery problems, so you have come to the address!

  1. Download and install Battery Calibration app
  2. Fully charge the smartphone (be sure to 100%! If the smartphone cannot be charged up to 100% – hold it on charge for about 4 hours and then continue)
  3. Launch the application and click “Battery Calibration”
  4. Disconnect the charger
  5. It is advisable to give the smartphone a full discharge after calibration

After such a calibration, you can use a smartphone with one amendment – wait for a full discharge and charge only up to 100%. Otherwise, incorrect data may appear.

It may take a week for the system to start showing the correct battery charge.

Calibrating the battery level through custom recovery

Calibration through custom recovery can help those who do not turn on their smartphone / tablet due to incorrect readings. For this method, you must have installed

  1. Launch Recovery
  2. Click Advanced
  3. Select "File Manager"
  4. Open the data / system / directory and click on the batterystats.bin file
  5. Click "Delete" and confirm with swipe
  6. Turn off your smartphone – charge up to 100% and try turning it on.

Nowadays, when autonomous devices running on batteries rule the world, the process of charging a smartphone, tablet or laptop has acquired some special importance and value. In this regard, problems arising from the battery or charging the device, as such, are one of the most common and annoying. And Apple products are no exception. Some users are faced with the fact that the iPhone does not correctly display the battery level, thereby creating confusion and unpleasant situations. Fortunately, there is a solution. In this article, we will consider in detail what to do if the iPhone incorrectly displays the battery charge. Let’s get it right. Go!

Very often, iPhone 6, 6S, 6S Plus users complain that their device does not correctly display the charge level. The following happens: at some moment, the percentage indicator simply stops updating, while the graphic indicator continues to work, which, of course, misinforms the user.

So what to do in such a situation. First, provide your phone with access to the Internet, it can be a mobile connection (2G, LTE, 3G) or Wi-Fi. Next, go to the iPhone settings and select the "General" item. Now you need to go to the "Date and Time" section and turn the "Automatic" switch to the active position. Wait five to ten seconds and then move the switch to its original position. Next step. forced reboot iPhone. To force a reboot of the iPhone, hold down the lock key and the Home button at the same time until the apple lights up on the dark screen. This method helps to solve the problem of incorrect display of the charge level on the iPhone 6, 6S.

Force reboot the device to resolve the issue

Another common problem among iPhone owners (usually earlier models: iPhone 5 / 5s, 4 / 4s). when the charge level “jumps”. That is, now you look at the screen and see that the phone is 40% charged, and in just 5 minutes the indicator shows 4%. The reasons for this problem may be:

  • Using Chinese cables for charging, as well as any others that are not original;
  • Using the smartphone at low temperatures (sub-zero temperatures can seriously affect battery performance);
  • Battery wear, loss of most of its capacity;
  • Replacing original iPhone parts and components with low-quality Chinese.

To fix this problem, start using the original Lightning and keep your smartphone in warm pockets if you are in the cold for a long time. Calibrating a battery can also help. It’s not really tricky. All you need to do. several times completely discharge the phone "to zero", and then charge again.

If this does not help, discharge the device to zero again, and then set it to charge from the mains. Even after the indicator shows 100%, leave the phone on charge for another hour or two, to be sure. After that, perform a forced reboot, holding down the lock and Home keys. Repeat this procedure two to three times. Of course, this approach will not benefit the battery, but what if the charge is displayed incorrectly and it becomes simply impossible to use the phone normally?

Now you know how to solve problems with incorrect display of the battery level on iPhone 4, 4s, 5, 5s, 6 and 6s. Write in the comments if this article helped you, share your experience with other users, and ask anything you like on the topic of the article.
