Issues with the battery or charge of your phone
Issue with the charger
Test with another cable to make sure.
You can also test the charge by removing the charging block
You can also test the charge by removing the power supply block, and connecting the USB end (Type A) into a compatible device.
If the issue is indeed coming from the charging cable, or the power supply block in which it’s plugged in, changing it should address the issue.
Validation of the energy consumption per app
Most smartphones allow to check the energy consumption of your battery for each app installed.
If an app is consuming a crazy amount of energy, uninstall or deactivate it from your phone.
Select a recent period that will give you a good overall idea of your issue.
Some phones need to be fully recharged to define a new verification period.
It is generally possible to close or uninstall some native apps in the phone.
Restart your phone
Reboot (power cycle) your phone by holding down the phone’s power button for 10 seconds.
If it’s a timely issue with the operating system or an app, the phone will be able to reload everything to work properly.
If the phone is frozen, and you cannot restart it, try a force restart.
The key sequence to complete a force restart can vary from one phone model to another. It’s usually a simultaneous combination of keys.
To know the one for your phone, make an internet search using the keywords that correspond to your phone.
Ex. Force restart Samsung S10
Make sure the phone’s contacts are not corroded or damaged
Check whether the pins seem straight and aligned to allow the charging cable to connect properly.
It is possible on some phone models to slightly adjust the metal pins with the help of a fine and pointy object, and as such address the issue.
See that your phone is fully charged
Leave your phone connected for a long period of time, such as all night, for example.
The software display of the charge level can sometimes be false. By leaving the phone on its charge for a long period, it could consider the battery’s total capacity as larger than initially evaluated.
Restore your phone to its factory settings
IMPORTANT: Save all media, contacts, apps and text messages that are archived and want to keep before proceeding.
Some of your phone’s parameters will need to be reconfigured after: mobile data blocking, NPA, Wi-Fi settings, Bluetooth function etc.
The steps to follow to reset your network settings will vary depending on the type of phone. Here are two examples:
Android: Applications → Settings → General management → Reset → Reset settings → Click on Reset settings
iPhone: Settings → General → Reset → Erase all content and settings
Check whether the issue is still there before configuring and personalizing your phone, or installing apps.
