Sometimes, devices indicate hardware problems that need to be fixed immediately.
One common issue that may require hardware repair is related to the battery.
Neglecting battery maintenance can lead to poor gadget performance and damage to adjacent hardware.
One reason for a battery overheating is the internal shock that occurs if the battery is dropped.
This is because the faulty battery has reduced current capacity, which is why battery voltage drops sooner.
If your battery is swollen, you should replace it immediately.

But you could alsorun your smartphone without its batteryfor a period.
It is used to measure the state of charge in a battery.
A hydrometer measures the gravity of a battery.
This indicates a problem with a single cell or the entire battery.
This showsbattery is unable to store any chargeand needs replacement.
Among hardware errors, one of the reasons could be battery failure to perform.

If you might disconnect the battery from your equipment easily, this is a simple check.
You cancheck battery voltage using a digital multimeterby setting the voltage measurement options and using probes on battery terminals.
Newer batteries usually have very low internal resistance compared to used or faulty batteries.
This can be checked by voltage measurement using a digital multimeter.
First, unplug the battery from the equipment and measure its open circuit voltage.
It should be according to battery specs.
Now plug the battery in the gadget and operate the gadget.
Check the battery voltage at terminals carefully.
It is because the battery of their unit is completely dead and incapable of providing any power backup.
