How do I know when my phone needs a new battery?

You cannot just wake up one morning and discover that your battery has gone bad. Batteries are not designed that way. There are indications, like warning signs that tell you your battery is going bad. Unfortunately, most people don’t pay any attention to such warnings. Of all the indications you might notice, the one that seem to be most obvious is the quick draining out of the battery

A bad phone battery drains out much faster when compared to its counterpart. If you used to use your battery for a day without charging it, and now you can’t use it for half that time without seriously looking for where to charge, you need to start thinking of how to get a new battery. However, you can’t rely on that alone to know when to get a new battery because there are other factors like a bad update or even bad app that can cause your battery to drain out much faster. So you have to be doubly sure about this before concluding that your battery is bad.

Another possible sign that your battery is bad is the fact that it never charges up to 100%. Even if you choose to leave it plugged to the charger forever, that is your business – it will not charge to its fullest! When your battery starts to behave that way, it is time to suspect the battery.

While taking much longer than usual to charge to 100% is bad for batteries, it is also not good for a battery to charge to 100% much sooner than it usually did. Either way, it is just as bad a sign that the battery will no longer serve its purpose.

Plus, when you physically observe your battery, and notice it to be swelling, you have to stop using that battery right away.

Can I test a car battery to see how much life is left?

This article is not just going to talk about phones and laptop batteries. If you are here to know whether it is time to pick up a new car battery, you are just in time for the conversation. Car batteries are about the trickiest when it comes to knowing their battery life. You can look at a car battery and think it is still normal, but unknown to you it as good as dead.

There are voltage brackets that makes it easy for you to indicate if the battery is still good. When you test a 2V battery with a voltmeter, the reading you get is what will determine whether the car battery is good or not.

A healthy 2V battery can read up to 2.3V or more when you measure the voltage coming out with a voltmeter. But if you do the measurement and you get something like 1.9V or lower, it is a bad sign for that car battery. Merely looking at it, the difference between 2.2 and 1.9 doesn’t look like much. However, it is a great deal in the battery world.

If it’s a 12V battery, it starts to read 11.4 or less when it is faulty. Therefore, you cannot know a faulty battery by merely looking at it. Instead, you can have it tested with a voltmeter to ascertain its true condition.

Conclusion

The idea of using consumer electronics like phones, laptops, or even car battery without stopping for a second to know how much life it has is not cool at all. Make efforts to check your batter health every once in a while. You can adopt any of the tips that have been mentioned above.
