Have you seen a video on YouTube, Tik Tok or on the web suggesting that you can increase the battery life of your Android and Samsung phone using the simple code *#9900#? What is this supposedly miraculous hidden code? We go around the question.
Ah, our phone’s battery life… That’s a tricky subject.
We all want it to last us as long as possible and we are always dismayed to see that it drains too quickly for our liking.
In particular, there are 10 tips on Android, as well as 10 tips on iPhone.
But there is one thing in particular that has been circulating on the web for a long time through Tik Tok or YouTube videos.
It is a question of entering a code like: *#9900# in his phone app to access secret features.
What is this code? What type of phone is it valid on? Does it really help him? We go around the question.
What is code *#9900#?
We took the example of the code *#9900#, since there is one that circulates a lot on the web. This is actually the USSD code for Samsung smartphones.
What is a USSD code?
It is an acronym in English for Unstructured Supplementary Service Data. In French it can be translated as Additional Services for Structured Data.
These codes usually start and end with an asterisk
and a pound sign (#).
However, they should not be confused with the two-digit codes of your telephone provider.
What does a USSD code do?
Without going into too much detail, these are essentially codes that allow us to access certain technical information from our phone.
We will often talk regarding a hidden menu, hence the idea that these are secret codes.
In the case of the code *#9900#, it takes us to the Samsung SysDump menu.
In this information menu, we can get several technical details regarding our device. The build number, the IIEM code, the strength of the cellular signal, statistics, in short, several technical details.
There are also some features that can help solve problems.
It is in this last perspective that videos are circulating on the web letting us believe that we can solve problems, including our battery life problems. However, it is necessaryBE VERY CARREFULLY
. Some features in this famous menu can cause other problems if you decide to press anything without knowing what it is.
What does the Batterystats Reset function do? In these videos inviting us to enter the USSD code *#9900# and to enter this famous ”secret” menu of information, we are then told to press:Batterystats Reset
.
Is it a magic button that actually miraculously boosts battery life?
Sorry, but no, not at all.
Its name says it, it allows you to reset the battery statistics.
Tapping on it will essentially erase all battery data and statistics that had been recorded by our phone.
We are talking here regarding the charging history, the battery levels in the past, the time of use of the device, etc.
This comes in handy in a perspective where we want to recalibrate the statistics of our battery.
Example, our phone displays that there is 75% energy left in the battery. In reality, the information may be incorrect due to poor calibration and the real information is more like 70%.
In short, it’s not a magic option that suddenly boosts battery life.
At best, it just allows us to have a better picture of the real autonomy we have left on our phone.
What does the function: Low Battery Dump do? Also in these videos and in the ”secret” information menu, we are also told that we must activate the function:Low Battery Dump
. Many will claim that the combination of functions: Batterystats Reset et Low Battery Dump
solved all our battery problems.
Again, that’s not true. Everything the function does: Low Battery Dump
it is to generate a report when the phone reaches a critical battery level.
Thus, if our phone discharges to a level below 5%, the phone generates a report where it records all the information regarding the state of the phone’s system and the errors that our device encounters.
This report comes in handy specifically for developers and technicians so that they can diagnose potential problems with the phone when it is running out of battery.
In short, it is a function that is totally useless for ordinary mortals and that will in no way solve our battery life problems.
How to check the status of your phone battery?
The best way to check the battery status of your phone is still to go to the settings that might be described as ”regular”. We are talking here regarding the application: Parameters, Settings or other labels of the kind.
In it, we always find a tab: Battery or Battery that allows us to check the state of the battery, the applications that drain the most energy and options to save energy consumption.Otherwise, on Android phones there is the USSD code *#*#4636*#* #
which can also allow us to obtain the information.
What to do to increase battery life?
As we have seen, there is nothing in the USSD codes that allows us to really extend battery life.
On the other hand, there are 10 Android tips and 10 iPhone tips with easily accessible features that allow us to reduce our battery consumption.
Other reasons why a battery drains quickly
If our phone is really struggling to hold its charge despite doing the things mentioned above, it might be due to three main reasons.
A bug in an update
We all know someone who has complained regarding their phone charging faster following an update.
Especially on the side of iPhones and iOS updates.
It is not impossible indeed that the update has a bug and causes some concern.
Unfortunately, there isn’t a phone that necessarily reacts the same way to an update.
In such a case, one can simply wait for another update and hope that this one fixes the bug.
A virus or malware
We shouldn’t be afraid, but it’s also possible that our battery will drain quickly due to malware running in the background.
This is also one of the clues to know if our phone is infected.
To be sure, just do a scan with one of the best mobile antivirus.
An outdated battery
It is inevitable, over time the battery of our phone disintegrates. By dint of use, it slowly loses its autonomy.
In a situation where our battery is really difficult to hold its charge, it may be that it has become obsolete.
We can then think of replacing it, whereas it generally costs between $75 and $100 depending on the model.
