The battery remains the cornerstone of our smartphones, but unlike other components, it has a limited lifespan and its capabilities decrease over time. How do you know when the time has come to replace it?
All batteries degrade over time
All batteries will see their capacity diminish over time but their performance does not drop suddenly. It is a gradual process. Over time, the battery life after a full charge will decrease and the battery will need to be recharged more often until the time comes for replacing it.
If you are lucky you may never need to replace your battery and it will hold up until you change your smartphone or tablet but it will not always be the case and you will have to go through The renewal box. When a battery is dying, some signs will warn you that it is time to replace it. In particular, you will feel that your smartphone is discharging faster than usual and that the autonomy offered after a full charge is no longer what it was originally.
How to tell if your battery is healthy?
On an Android smartphone, it is quite easy to know the health of the battery since it is in a hidden menu accessible via the secret code *#*#4636#*#* to enter directly in the dialer of the Phone application. You will then see various encrypted information.
If the value 100 is indicated next to your battery, it’s all okay if it says 70 or 50, then it’s already started to lose some of its capacity. Your phone therefore tells you directly whether the battery status is good.
Of course, when its performance begins to deteriorate, you do not have to replace it immediately. It is possible, indeed, that its capacities decrease but that the autonomy of your telephone remains correct. On the other hand, when it starts falling more than normal and you will be obliged to constantly recharge the device, then it is the time has come to change it.
Of course, this decision is yours alone. As long as you can still use your phone and the autonomy offered remains almost correct, nothing forces you to do so. But if you want to make the most of your device, it will always be better to have a battery offering the best of itself.
Observe the loading and unloading processes
The evolution of charging and discharging processes is a good indicator of the health of your battery. If the fact that your battery is discharging faster than normal does not necessarily mean that it is at the end of its life, excessive consumption from an application or a process may also be involved when the gauge Indicating the percentage of your battery drops or climbs abruptly (from 10% to 20% for example or the reverse), this is usually a bad sign.
If you have a removable battery
If the battery of your smartphone is removable , characteristic increasingly rare since the manufacturers have gradually opted for metal designs, including on the mid-range, then a simple glance will sometimes make a diagnosis . The wear often leaves physical clues about the batteries, clues that do not deceive.
This is systematic, in other words, even if you do not observe any signs of wear and tear by removing the back cover of your phone, it does not mean that your battery is not at the end of its life. However, if your battery is swollen or if you notice rust stains, then it is high time to change it, your safety is at stake. The different cases of explosion of the Galaxy Note 7 have recently demonstrated to what extent a defective battery can prove dangerous for the user.
Using a diagnostic application
There are several diagnostic applications to check the health status of your smartphone battery but Ampere is probably the most complete. It tells you exactly how much you charge when you charge your smartphone, how fast your battery is discharging, and also allows you to test your different chargers to see which battery is the most suitable. It also allows you to set whether the problem is with the battery or your charger.
Check background processes
Before deciding to replace your battery, be sure to check that everything is working normally and that an application or process running in the background is not abnormally emptying your battery.
How to replace the battery of your smartphone
If your smartphone (or laptop) offers a removable battery, then it will be very simple since you will simply have to buy another one, then put it in the place of the old one. Be careful to buy an official battery and not a Chinese counterfeit, although less expensive, Chinese batteries are often unreliable and in case of problem, you could not return to the manufacturer.
If, on the other hand, the battery of your mobile device is not removable, then it will be more complicated. You can, of course, find a battery very easily on the internet and even tutorials explaining the procedure to follow, but it is not necessarily the ideal solution.
Very often, the battery will be difficult to access, once the phone is disassembled, it will be necessary to remove other components, which could then increase the risk of damaging the device when replacing the part as on the Samsung Galaxy S6 , for example. These devices are not designed to be disassembled by the user. The wisest solution is therefore to call directly your dealer (if he offers this service) or your manufacturer.
