How to calibrate iPhone and iPad battery for longer battery life
The battery life of mobile devices has always been a byword. And although apple devices in this regard compare favorably with competitors, the problem is sometimes exacerbated with the release of a new firmware or its update, when you can see with the naked eye that the iPhone holds a charge much worse. Fortunately, this problem can be solved using the old "grandfather" method, calibration of the battery controller.
The essence of calibration is to “reset” the controller, which controls the battery and is responsible for the boundary limits of charge and discharge. The battery capacity changes over time and the controller can "play prank" by uncharging it or, on the contrary, turning it off too early. This often happens after updating the firmware on the iPhone or iPad. So, there is a possibility that after calibration the battery will come to your senses and show the best results. Performing it is quite simple.
- First of all, you need to completely discharge the battery of your iOS device. Speaking completely, I mean to discharge until the device is completely turned off. So turn on the video, play games, listen to music and load your gadget to the fullest.
- After that, put the device on charge and charge it to a magical 100%. It is recommended that you use a mains charger to provide the required charge current.
- As soon as your iPhone or iPad charges up to 100%, leave it to hang on the cord for another hour (to be sure).
- Now you need to disconnect the iOS device from the network and use it in normal mode until the battery is completely discharged (completely!). Never connect your device to a charger or computer. It is very important! Otherwise, the enchantment will be dispelled and our mantra may not work.
- Once again, charge the device to the eyeballs and leave it to charge for another hour (as described in paragraphs 2 and 3).
- Now it’s all. Your device’s battery is calibrated. Congratulations!
I know that to complete all these steps will be a bit tedious, you will have to change your habits. do not connect your iPhone to a computer and charge strictly up to 100%. But believe me, it’s worth it. At least we help a lot.
If you have a similar problem, try to calibrate anyway. It will not take much time and effort from you, but the result may pleasantly surprise you.
Nonsense is all that. You just saw what you wanted to see. In Li-Po charge controllers, the charge level is tightly controlled by the battery voltage and is tied to the discharge curve. And nowhere do these levels float away. If the controller has an upper limit of 4.25V, it will turn off the charge at 4.25V, no more and no less. And after a year, not surprisingly, he will also turn off at the same voltage. And in the same way, it will turn off the phone when it reaches the lower limit. Regarding this myth, remember, even Android developers unsubscribed. In iPhones, everything is implemented the same way. And about the fact that the phone began to hold longer. Maybe you have some kind of buggy process there, but you have not rebooted even once? And during calibration, they rebooted and magic occurred.
The topic is controversial, I agree. But even if it is a placebo, so be it. The main thing is the likelihood that this will work ^^
Bullshit of course. The battery may run out for various reasons. If after the release of the new firmware this happens for everyone without exception, then this means a firmware bug. And if this is individual, then the problem is not in the firmware, but rather in a change in the intensity of use of the phone, a bug in some third-party application (usually after updating it, or simply not adapted for the firmware version), changing operating conditions (humidity, changing the temperature regime etc.), or it’s just corny the battery is dead, and it should be replaced. In general, it can be discharged from anything, and the calibration of the controller is pure nonsense. The controller can only fail, for example, due to an excess of power supply to it, and then its replacement will already be required :))
Firstly, Apple uses Li-ion batteries. Secondly, if in such batteries the particles are often in motion (discharge / charge), this positively affects its shelf life. Thirdly, Apple itself recommends performing discharge / charge cycles once every 1/2 month for calibration, which leads to the correct display of the charge.
For li-ion, this is not nonsense and not a myth. In any case, Nokia employees say so. over, the developers recommend using their battery to increase its service life. So this is nonsense, and maybe not nonsense, just protest worse, it still won’t. It is also advisable to disable the definition of geolocation.
Help, yesterday there was a glitch with an iPhone. During the call, it seemed to turn off, but there was vibration without stopping until I rebooted it. After turning on, the battery began to melt before our eyes. Although literally two days ago everything was normal. What can be done. I changed the battery in January.

Features of working and replacing the battery on the iPhone 4S
For long-term operation of new smartphones require large reserves of energy. Therefore, the battery should not only provide the touchscreen with “force”, but also a powerful processor. Currently, of all existing rechargeable power supplies, the optimum amount of properties is possessed by lithium-ion batteries. They are equipped with most gadgets, including the iPhone 4S.
IPhone 4S Battery Features
The capacity of such a battery is 1420mAh. This allowed to increase the operating time of the smartphone in different networks without recharging. However, the parameters of the gadget, the presence of additional elements that were not available in previous models, had an impact on the size of the battery. Despite these changes, the rated voltage has not undergone major changes.
In addition, the battery is lightweight and can be fully charged in an average of 3 hours. Due to the lack of a memory effect, charging can be carried out at any time. At the same time, the level of self-discharge does not exceed 7-10 percent per year.
Why is it necessary to replace the battery on a smartphone?
One of the drawbacks of a battery is that it can be destroyed due to overcharging or substantial overheating. These factors lead to the fact that the device completely stops working. In addition, after a certain number of full charge cycles, the battery capacity decreases by 20 percent. These circumstances make it necessary to replace the battery of the iPhone 4S.
Signs of battery failure
A decrease in battery performance occurs after about six months of active use of the gadget. However, users may notice that:
- the gadget began to turn off at short intervals;
- the battery does not charge at full power;
- Charging lasts no more than 10 hours.
Sometimes you may notice that the charging status is not displayed correctly on the smartphone. All these signs indicate that you need to contact a service center as soon as possible to replace the part.
How is the battery replaced?
In iPhone 4S, replacing the battery yourself is very difficult. This is due to the fact that, unlike other devices, it cannot be removed. Therefore, it is best to seek help from a specialized service center. You can find out more about him at http://www.my-apple.ru/zamena_akkumulyatora_iphone. It will be replaced in a short time using original batteries. This makes it possible to extend the life of the device, to maintain performance at the right level.
Despite the fact that the work takes about 30 minutes, diagnostics and testing for charge-discharge are mandatory. All parts installed in the service center are warranted.
How to extend the battery life of the iPhone 4S?
If you want the new battery to last a long time, you need to use your smartphone regularly. Thanks to this, the electrons will be in constant motion, which will help maintain the battery in good condition. As already noted, overheating causes the most damage to the gadget. Therefore, do not leave it in the sun and always keep it in a special case. It is necessary to carry out a full recharge cycle at least once a month. This means that the battery is first fully charged and then completely discharged.
In conclusion, it should be noted that you can find out statistics on the use of the gadget since the last full charge in the Settings menu. This will allow you to correctly calculate the time when you need to conduct a full recharge cycle.
