Now, taking into account that this is a terminal that was stopped selling for a long time, the most normal thing is that the battery is not new.Keep in mind that this is in the end a component that tends to wear over time and if we add that the latest versions of iOS may not be so thought for it, it would not be strange at all that in the middle of the middle of theday already had to connect to the current.Therefore we can find at this point that at the end the autonomy of the device can change depending on this factor and the use of the equipment.

Check your health in adjustments

Si acudes a Ajustes > Batería > Salud de la batería, podrás encontrar un porcentaje que indica el nivel de deterioro de esta, siendo 100% su mejor estado.As we said before, the batteries are in the end a component that is naturally exposed to degradation with use, so it enters within the forecasts that have worn out.Of course, if you notice that the percentage has suddenly dropped a few levels in a short time, it will probably be that the battery has a defect.

It should be noted that in case there is degradation that is considered excessive, the operating system will show you an indication in which it will be told clearly if the device needs to replace its battery to work again normally.In any case, you should know that this is not always a highly reliable percentage, since being able to measure accurately this value is something complicated and despite the complex algorithms that the iPhone uses, it is not always right.

What you can do if you suspect from the software

Although the battery is considered hardware, since it is a tangible component of the device, the truth is that a bad optimization by the software can cause more than one mismatch that causes that the autonomy of the terminal is negatively affected.It is at this point that we recommend you perform the following two actions if you have suspicions that this may be the cause of your problems:

How much does Apple charge for replacement?

There is an option that is not in your hand directly by not being you who does it, although you have the decision: take it to Apple.This is a recommendation that we can do at the moment when you discard that the software is to blame for your problems and you are sure that the battery is worn and requires a replacement.In the official technical services of the brand they can offer you a replacement that is sometimes carried out in the day and always with full guarantees that it will be an original battery.

Now, this replacement is not free unless it is a factory defect.Apple asks for 55 euros for this, to which you could have to add 12.10 euros for shipping costs if for any reason you cannot or want to go to an Apple Store and request the distance reparation, intervening in that case a service a serviceof messaging and with major waiting times.In any case, identical guarantees are offered, as well as the battery itself in case you fail after the replacement.

Tips if you want to change the battery yourself

If you do not convince you the idea of taking the battery to an Apple Store or to a third -party service, the truth is that you will have no choice but to change it on your own.It is possible to do it, although it is not something simple because it implies having to open the device for not having a removable battery.In following sections we explain how to do it, although not before highlighting an important point about the risks of this replacement on your account.

Risks that this process implies

The first thing you should be clear about is that, although the explanation is detailed, it is advisable to have certain technical knowledge.It is also essential that you have certain skills that allow you.And we say all this because the phone could be unusable if the process is not done correctly or if a component is touched that was not due, being worse the remedy than the disease.

Another aspect that you must take into account is referring to the guarantee.We understand that given the years that the terminal has, it has already lost the coverage with Apple, but if you had it you should know that you will lose it at the same moment when you proceed to open the terminal.To this we must also add the fact that you will not have an original battery.And yes, there are many stores that offer this component with that idea, but they are not really, since only Apple and authorized services have these components.Therefore the experience of use over time may not be the same.

Steps you must follow

If you look trained to carry out this replacement process and also assume the previously commented risks, you can continue reading to see the steps to follow in this process (you will also find a video of Ifixit at the end).Of course, first of all you must have bought a battery that is compatible, which you can find in Amazon, having a variety of options that fit your budget and needs, also including tools to proceed to replace.
