Avoid the battery problems of your iPhone 8 — 2022

If the battery of your iPhone 8 does not last long, it does not necessarily have to be due to a problem with this component and therefore it must be taken for repair. 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.

Battery life on iPhone 8 (estimate)

The batteries of the iPhone 8 and 8 Plus are, respectively, of 1,821 mAh Y 2,675 mAh . This is on paper, since the way to really measure the batteries in an Apple team like these is relatively different from others of the competition. This is due to the optimized processors and the iOS operating system, capable of better managing them. In any case, it is not possible to give a fixed autonomy data that works for everyone, since in the end it will depend on the use made and the level of wear of the device.

Taking into account that both had 100% battery health and what was considered a normal use , the iPhone 8 Plus should reach the end of the day without a problem, considering that the use made of it is to make or receive a call, surf the Internet, check social networks and use messaging apps. Something less in duration would have the iPhone 8, which could suffer something more and need the charger before the end of the day. In any of them, the autonomy would be reduced if mobile networks are used permanently, if a lot of multimedia content is consumed or if it is enjoyed for hours of video games.

We insist on emphasizing that it depends on the use made of these iPhones and the applications used, it may vary more or less. In any case, that the battery life under normal circumstances requires you to charge the phone at least once or twice before reaching the night is a clear indication that something is wrong. Therefore, if you are in this situation, we recommend you continue reading this article.

How to make sure it's optimized

Beyond giving advice about what kind of uses you should do so that the autonomy goes better, the truth is that there are a series of settings that you should review in order for the battery as such to last longer. For this reason, you should always keep in mind what we comment on in the next sections.

Update the software to the latest version

As strange as it may seem, there are versions of iOS that manage batteries worse than previous ones and this is usually due to some failure in the autonomy optimization. This sometimes causes a certain fear of updating the software, but the truth is that it is the most recommended considering that you will be able to have the latest security improvements that are added to possible visual and functional novelties.

iPhone 8 and 8 Plus

Apple always tends to react quickly with failures in its updates, so in case your current version is consuming too much battery of the iPhone 8, in the new one it should improve. If you go to Settings > General > Software Update you will be able to find the latest latest version ready for download (via WiFi) and subsequent installation. If none appears, it would mean that you already have the device in its latest available version, so we recommend that you also verify what we comment on in the following sections.

Check how much apps consume

There are times when it is not iOS as such that is generating the most consumption, but rather the applications you use that are not optimized. If you go to Settings > Battery you will be able to find a list of apps you use and how much they are consuming. If you also click on Show activity you can find more information about them. Our advice at this point is to verify that all of them are having a normal consumption based on the time you use them.

Yes you detect that they consume in excess it could be that the developer has not optimized the application. Normally this is corrected with updates, so we advise you to go to the App Store to check if there are more recent versions of that/those app. In case there are no pending updates, it is advisable that you uninstall it and reinstall it, which will erase all its data from the iPhone and therefore a possible junk file that was causing a problem can be deleted. with consumption.

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, 100% being the highest, which implies that the battery is at full capacity and has not been degraded. It is natural that this percentage goes down as time goes by, since the battery is one of the components that suffers the most degradation in a device. However, it is no longer normal for this level to have dropped considerably in a short time, such as going from 100 to 96 in a matter of weeks.

The cut level It is around 80%, with lower parameters already indicating 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 is happening 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 it is possible that the algorithm is not expressing the exact number of degradation.

Check iPhone charging cycles

If you are seeing that your mobile has problems, it is possible that the charging cycles are already consumed. We must take into account that a specific load cycle from 0 to 100% when it is downloading. An iPhone 8 battery typically has around 500 cycles. If it exceeds them, it is possible that it begins to deteriorate by not charging at full capacity. This is mainly noticeable in the autonomy since you will notice that it lasts much less and drops below 100% quickly. The only solution you have to this is through a battery change since the charging cycles cannot be recovered.

To consult the cycles you must go to Settings > Privacy and click on Analysis and improvements. In the latter you must access Analysis data . There you will find an extensive document that you must export to another format in which you can locate the term batterycyclecount , which will indicate the cycles you have consumed from the battery.

What to do if autonomy is not what you want

If at this point you have verified that everything is correct, you can perform a series of steps to make the battery of your iPhone 8 or 8 Plus perform again the way it should.

Restore iPhone 8 without backup

As you may have seen in previous sections, the software sometimes plays tricks by providing suboptimal performance on your iPhone. The most definitive solution to end it is to restore the device and set it up as new iPhone , in such a way that the possible internal errors that are in your backup cannot sneak back into the terminal.

Although this restoration can be carried out from Settings> General> Reset, clicking on Delete content and settings, the truth is that it is perhaps not the most recommended. The best way to make a full restore It is through a computer, since in this way all the data is eliminated and not simply overwritten as is the previous method. For this restoration you can use a Mac The PC Windows . On Apple computers with macOS 10.15 or later, you must use Finder, while on those with macOS 10.14 and earlier, you will use iTunes, the same program that you must use in Windows. Once you connect the iPhone via cable to the computer and open those programs, you should go to the device management part and choose the Restore iPhone option.

Change it at 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 in the battery itself. Therefore, the best recommendation is to go to Apple or an Authorized Technical Service (SAT). In these places they have more precise tools to run a device analysis and obtain a clearer diagnosis of what is happening. The replacement price of the battery in the official stores of the company, in case that is the proposed solution, it will be of 55 euros (either an iPhone 8 or an iPhone 8 Plus). In other SAT the price could vary, although not with a very big difference.

This repair could leave you free in some cases. If the device does not present a natural degradation over time and is due to a factory defect, they can change the battery even without the device being under warranty. Also if you have hired AppleCare + You will have this replacement at no cost. Of course, it must be said that if you cannot physically go to an Apple Store you will have to ask them to pick up the terminal at your home and that has a cost of 12.10 euros for shipping costs.

Change it on your own, with drawbacks

This could be the cheapest option , this being an advantage that can be considered important. You can buy a battery on your own, disassemble the iPhone to remove the old one and change it for the new one. This a priori sounds very nice, although there are several points to take into account that could make it not the best option you have to replace this component.

The first thing you should know is that you will lose the guarantee of the device if it still has it. On the other hand you will be putting a non-original battery which will probably give you a worse experience and may even not work on the device if it detects that it is not a reliable component. To this must be added the possibility that the phone could become unusable if during the process you make a mistake that affects another component, so it is not advisable to do so if you do not have certain knowledge and skills.
