If the battery of your iPhone 8 is short, it does not necessarily have to be due to a problem with this component and therefore it needs to be repaired. There are some other factors that can influence the ideal duration of this, so in this article we will show you how to solve those battery problems on your iPhone 8 or 8 Plus, as well as the instructions to follow in case you finally have to go. to a technical service.
How long should the battery of an iPhone 8 last
The batteries of the iPhone 8 and 8 Plus are, respectively, 1,821 mAh and 2,675 mAh . This is on paper, since the way to measure batteries in an Apple computer like these really is relatively different from others of the competition. This is due to the optimized processors and the iOS operating system, capable of better management of them.
For practical purposes it is difficult to give a number, but in normal use the iPhone 8 Plus should reach the end of the day. The iPhone 8 for its part would cost you something more and perhaps on some occasion you should resort to the charger before arriving at night.
We insist on emphasizing that it depends on the use that is made of these iPhone and the applications that are used, it may vary more or less. In any case, that the battery life under normal circumstances requires that you charge the phone once or twice at least before arriving at night is a clear indication that something is wrong. Therefore, if you are in this situation, we recommend you continue reading this article.
Update the software to the latest version
Oddly enough, there are versions of iOS that manage batteries worse than previous ones and this is usually due to some failure in optimizing autonomy. This is sometimes caused by a certain fear of updating the software, but the truth is that it is the most recommended considering that you can have the latest security improvements that are added to possible visual, functional innovations.
Apple always reacts quickly with failures in its updates, so in case your current version is consuming too much iPhone 8 battery, in the new one it will improve. For this you must go to Settings> General> Software update and if there is any new update, it will be here where you will find it ready for download and installation.
How much do apps consume you?
There are times when it is not iOS as such that is generating greater consumption, but it is the applications you use that are not optimized. If you go to Settings> Battery you can find a list of applications you use and how much they are consuming. If you click on “Show activity” you can find more information about them.
Verify that all of them are in normal consumption and that there is none that is generating more consumption than usual and, in this case, you should go to the App Store to check if there is any update of this that fixes this consumption problem. In the event that there is no update, you will only have to wait for it to be available or, in extreme cases, uninstall it if you think that it is not worth using with regard to the excessive battery consumption it generates.
How is the health of the battery?
Since iOS 11, the version that the iPhone 8 and 8 Plus natively brought, there is a section dedicated to the state of battery degradation. If you go to Settings> Battery> Battery health you can find it. It is indicated with a percentage, with 100% being the highest and that implies that the battery is at full capacity and has not degraded. It is natural that this percentage goes down as time passes, since the battery is one of the components that suffer the most degradation in a device. However, it is no longer normal that this level has degraded considerably in a short time, such as going from 100 to 96 in a matter of weeks.
The level of cut is around 80%, having lower parameters already indicate a degradation of the battery which implies that its operation will already be very different. In those cases, you will be able to see information on that same screen, which indicates more accurately what happens to your battery.
In any case, you should know that this percentage is not always true to reality , since it is obtained through a series of internal calculations and the algorithm may not be expressing the exact degradation figure. This we already told earlier in an article in which we showed a kind of trick to increase the health of the battery of an iPhone, which is not really such.
Restore your iPhone 8 without backup
As you have seen in previous sections, the software sometimes plays tricks providing poor performance on your iPhone. The most blunt solution to end it is to restore the device and configure it as a new iPhone , so that the possible internal errors that are in your backup cannot slip back into the terminal. You can do it from Settings> General> Reset and clicking on “Delete content and settings” , although it is always recommended to restore from a computer, as discussed below.
From Mac with macOS Catalina or later
- Connect iPhone to Mac via cable.
- Open a Finder window and click on the name of the iPhone in the left bar.
- Go to the General tab and click on “Restore iPhone” .
- Follow the steps that are shown on the screen and do not disconnect the device during the process.
Mac with macOS Mojave or earlier
- Connect iPhone to Mac via cable.
- Open iTunes and go to the management part of the device by clicking on the icon at the top.
- Go to the Summary tab and click on “Restore iPhone” .
- Follow the steps that are shown on the screen and do not disconnect the device during the process.
Windows PC
- Connect iPhone to computer via cable.
- Open iTunes and go to the management part of the device by clicking on the icon at the top.
- Go to the Summary tab and click on “Restore iPhone” .
- Follow the steps that are shown on the screen and do not disconnect the device during the process.
If you go to an Apple Store or SAT
If these previous methods do not work for you and the battery of your iPhone 8 continues to give you problems, it is more likely that the failure lies in something physical of the battery itself. Therefore, the best recommendation is to go to Apple or an Authorized Technical Service (SAT). These places have more accurate tools to run a device scan and get a clearer diagnosis of what is going on. The price of the battery replacement in the company’s official stores, in case that is the proposed solution, will be 55 euros (either an iPhone 8 or an iPhone 8 Plus). In other SATs the price could vary, although not with a very large difference.
This repair could be free in some cases. If the device does not show a natural degradation over time and is due to a factory defect, they can change the battery even without the device under warranty. Also if you have contracted AppleCare + you will have this replacement at no cost. Of course, it must be said that if you cannot go to an Apple Store physically you will have to ask them to pick up the terminal at your house and that has a cost of 12.10 euros for shipping costs.
What is not recommended to do
On the internet there are tutorials that show how to change the battery of an iPhone 8 or 8 Plus yourself . In fact parts are sold at a not too high price, but in the end it is a risk that you assume on your own and that in no case is covered by Apple. The fact of installing a battery that is not original could already generate a problem in itself, but it is also that you will lose the guarantee if your mobile phone still maintains it. If you are also not very tricky in these aspects, you could accidentally damage some other component and render the phone unusable.
The same happens if you take the phone to an unauthorized technical service . We understand that the savings that could result is the least striking, but you should bear in mind that no matter how professional they are in these places, original parts are not guaranteed and therefore neither that the battery life will be again like that of the first day. Both in this case and in the previous one, you should value the pros and cons well, knowing that in the end it would be a decision on your own and risk.
