6 Facts About Cell Phone Batteries You Might Not Know

Table of Contents

The battery is one of the most important components in our cellphones or smartphones. No matter how good a cellphone we have, it will not be cool if the battery has a small capacity and likes to drop quickly, even though it hasn't been used all day.

But the battery runs out quickly not only because of its capacity. Even a fairly large capacity battery can experience a drop condition over time or run out quickly. So now more and more cellphones are equipped with jumbo capacity batteries, even up to 5000-6000 mAh.

 

These batteries are also equipped with a charger that is already fast charging alias fast charging. This was added by the HP manufacturers because consumer needs for long lasting batteries are getting higher.

 

However, fast charging technology is also said to have an effect on battery life. In addition, the medium capacity battery, if it is frequently charged, will also shorten its lifespan. Is it true?

Here are some gossip and facts about the world of batteries, quoting from CNet.

1. The fast charging feature will not quickly damage the battery

This is one of the biggest fears of smartphone owners with fast charging capabilities. Once charging, you can use a charger above 15 watts. The incoming electricity speed is also higher. It's like filling a bucket from a faucet with very strong water. It will fill up quickly, but it will spill out quickly too.

 

However, according to HP battery experts, today's smartphones will not be damaged just because of the super charging speed. This is because HP batteries are designed to absorb electrical power in two phases.

 

The first phase reaches 50-70 percent of battery capacity. The speed will be super. Filling from zero to 70 percent can only take 1 hour or 1.5 hours.

 

But after that, the speed will automatically slow down to close to 100 percent. This is to avoid damage to the battery.

This technology was developed since there were many cases of the Samsung Galaxy Note 7 which exploded a few years ago. At that time, cellphones were not equipped with two-phase charging speeds like this, so the battery exploded.

2. The battery will not overcharge

Back again to the parable of the bucket. If the bucket is full of water, the water will automatically spill. There will be no more water that can accumulate on top beyond the capacity of the bucket. This also happens with our HP batteries.

 

If it takes too long to charge, it doesn't mean the electric power in the battery will exceed 100 percent. Unless there is something wrong with the components. So, modern HP batteries will not overcharge.

 

Venkat Srinivasat, a battery researcher at Argonne National Laboratory, explained that modern cellphones are equipped with automatic charging stop technology. Once the charged battery reaches 100 percent, the cellphone will automatically cut off the electricity that goes into the battery even though the cable is still attached.

 

Generally HP will also have a warning mode when the battery is full so that we immediately remove the cable. Newer cellphones are now recommended to be charged up to 80 percent in order to maintain a longer battery life.

3. Don't leave the battery zero

Battery that is too full is not recommended. Likewise the battery is too empty. Sometimes we may accidentally empty the battery to really 0 percent because there is no charger. This action is actually not healthy for the battery itself.

 

When the battery is at zero, there will be a chemical reaction in the battery that can affect battery life. That's why HP now has a reminder mode before the battery is completely depleted. Even some HP will automatically turn off when it reaches a critical percentage even though it's not completely zero.

 

If you want your HP to stay healthy, try to always recharge it before it reaches a critical percentage. Experts suggest, the most ideal is when the battery is 30 percent remaining. Still above the critical level but low enough for a recharge.

4. High temperatures can damage the HP battery

Ambient temperature also affects battery life, you know. Hot weather apparently can damage the battery more quickly. That's why it's not recommended to put the cellphone in a place exposed to direct sunlight, such as on the edge of a window or on a car dashboard.

 

In extreme conditions, the weather is very hot plus the condition of the cellphone is not so good, the battery might explode. The CEO of battery company Cadex Electronics, Isidor Buchmann, said that cellphones should not be exposed to air temperatures above 30 degrees Celsius.

 

The point is how to keep the cell phone at room temperature. For example, if you put it in a bag, try to keep it close to a slightly cold water bottle. When you're outside, occasionally cover the cellphone with a half-wet cloth (make sure no water gets in and damages the cellphone).

5. Using a charger other than the default charger will not damage the cellphone

Many think that our cellphone batteries are damaged quickly because we don't use the default cellphone charger. The original charger alias we got when we first bought a cellphone.

But, as long as you don't use a damaged cable, it doesn't really matter if you want to use a charger other than the one that comes with your cellphone.

 

Indeed, not all cellphones can be treated with chargers like this. For example, for Huawei or OnePlus cellphones, they have a special charger designed by themselves. Meanwhile, other Android cellphone batteries, including Samsung, generally follow international standards. So it can be filled with other chargers of the same type.

 

But we need to pay attention to other chargers that we want to use. Make sure the specifications are the same as the default charger. Do not let us charge HP with a charger whose capacity is much smaller or bigger than it should be.

6. The secret to keeping the battery last

There are manyways we can do to keep the battery life long. One of them is by using features that can save battery power. So we don't need to be too often and too long to attach it to the charger.

 

And there's no need to stress if our batteries eventually run out quickly after months of use. All modern cellphones are the same, the battery will experience a decrease in performance over time. But its durability can be longer depending on how we take care of it.
