Tips to avoid damaging the iPhone battery

Let’s get to the heart of the matter immediately and discover, together, some tricks not to ruin the iPhone battery . I want to tell you that the advice listed in the following lines constitute a sort of vademecum that in principle applies to all smartphones and not only to those produced by Apple (all mobile phones currently on the market, in fact, are powered by ion batteries . of lithium ).

If your iPhone is protected by a case, the first piece of advice I would like to give you to avoid damaging its battery is to not leave it connected to the electricity supply . Although the iPhones produced in recent years all integrate a chip that blocks the flow of energy when the battery reaches the maximum charge level, it is advisable to avoid leaving it on too long to avoid possible overheating due to bad heat dispersion caused. right from the use of a protective case. If you really want to leave the iPhone charging overnight or in any case for prolonged periods, be careful to  remove its protective case (especially if it is an unofficial cover or, in any case, not produced by reliable companies).

Another important precaution that must be followed in order not to damage the iPhone battery is to avoid temperatures that are too high . Leaving the iPhone near a heat source (e.g. near a stove, near an oven, in direct sunlight, etc.), not only could compromise the correct functioning of the battery and the duration of the single charge, but it could even constitute a serious danger to the safety of the surrounding people, as the “iPhone by” could suffer irreparable damage or even catch fire (this is a rather rare situation, but still potentially verifiable). Generally speaking, the ideal range is between 16 and 22 ° C.

You should also  avoid too low temperatures . When the device is used in a very cold environment, the battery life can sometimes be shorter, but this is a temporary condition: once it is brought back to optimal temperatures, the battery will return to its normal performance.

I also advise you not to  use the iPhone while it is connected to the power , as this could also negatively affect the “health” of the device’s battery. If you just send a few messages to a friend or do a quick search on the internet while the iPhone is charging it is not a problem, but avoid using applications that consume a lot of power (such as games or photo editing apps), because these could cause it to overheat and, consequently, compromise the correct functioning of the battery. If you notice any overheating while the iPhone is charging, unplug it, wait for it to cool, and then put it back to charge.

Many forums and websites in the past years have spread the “urban legend” that you should only charge your smartphone after the battery is completely discharged. Nothing more false! If this advice was fine for the “old” cell phones powered by Nickel-Cadmium batteries, whose total charge capacity decreased significantly if it was recharged before it was completely discharged, for lithium-ion batteries this is not true at all.

For lithium batteries, in fact, the exact opposite is true: if they are allowed to completely discharge, they can suffer irreparable damage which significantly decreases their capacity. For this reason, be careful  not to let the iPhone discharge completely and remember to charge it as soon as the battery level reaches 25-30% . In this regard, it may be useful to bring a power bank  or charger with you to use in emergency situations.

Do you use the iPhone as a “spare cell phone”? In this case, if you happen to not use it for a long time, charge it halfway . Also, if you think you won’t be using it for more than six months, remember to charge it up to 50% at least once a month . Keep in mind that if you store your iPhone with a completely discharged battery, it may run out to the point that it is impossible to recharge it again, while if the device is left inactive for a long period on 100% charge the battery capacity may deteriorate and its capacity. autonomy could be affected.

I also advise you to always use  original accessories and chargers , in order to avoid that a higher or lower voltage than that required by the battery is supplied, which could damage it irreparably. If you really want to use third-party accessories, make sure they have the MFi (Made For iPhone) certification.

Last but not least, try to always keep iOS updated to the latest version . What does it have to do with not ruining the iPhone battery? Simple: Apple’s mobile operating system updates often include the latest energy saving technologies and by running them you go to make sure you can always and in any case take advantage of them, not to mention that any software bugs can cause incorrect use of the battery charge and that a correction can always and only come via update.

Monitor the battery status of the iPhone

After considering the tips for keeping your iPhone battery healthy, let me tell you how to monitor its status  via a feature that has been made available on all iPhones, starting with  iPhone 6 and later models updated to at least iOS 11.3 . 

To reach the function in question, grab your iPhone, access the home screen and / or the iOS app library , select the Settings icon (the one in the shape of a gear wheel ) and tap on the  Battery item . As you can see, in the screen now displayed there is a graph that indicates the energy consumption recorded in the last 24 hours of use or in the last 10 days , complete with information about the apps that have consumed the most energy.

To see the battery charge capacity, tap on the Battery status item  and, in the screen that opens, check the percentage indicated in the Maximum capacity item . If the indicated value is less than 80%  (if the iPhone has already been used) or less than 100% (if the iPhone is new), it would be better to contact Apple’s customer care to possibly proceed with its replacement or replacement of the device itself.

I point out that always from the above screen you can activate the Optimized Loading function , turning ON the relative switch, which is available for iPhones updated to at least iOS 13 . This is a feature designed to limit battery wear and improve battery life, reducing the time the iPhone spends fully charged, leveraging machine learning to understand daily charging habits. When activated, the iPhone will charge up to 80% under certain conditions. The purpose of the algorithm is to keep the iPhone fully charged when unplugged

Replace the iPhone battery

If you are reading this section of the tutorial, you obviously want to replace the iPhone battery because you have come to the conclusion that it no longer works properly. Since the built-in battery in the iPhone is not removable, it is necessary to contact Apple or an authorized service center to replace it.

You can get in touch with Apple Support in various ways, here they are: by phone, via chat, by going to the Apple Store in person, etc. For all the details of the case, refer to my tutorial dedicated specifically to how to contact Apple .

Note that if your iPhone is still under warranty , you can get a free replacement by contacting Apple. If the iPhone is no longer covered by the warranty, the battery replacement by Apple is subject to a fee (visit this page to consult the updated list of costs to be incurred). If you think it will be useful in this regard, read my guide on how to check iPhone warranty .

If you think you have the right skills to replace the battery, however, you may find it useful to read the guide on  how to replace the iPhone battery  where you can find some general advice on how to complete the job in question. But I recommend: do not try your hand at such a feat if you are not sure what you are doing, because you could seriously damage your device.
