Quick Battery Charger -Introduction, Speed Control and Apps Working
People using electronic gadgets today are no longer patient enough to wait for 3 or 4 hours for a battery to be fully charged. This is the reason why many smartphone and computer manufacturers now use batteries that support fast charging in their devices. We now have smartphones like the Oppo Find X2 Pro (4260mAh) that can be charged to full capacity within 39 minutes. Most of the other Flagship phones from the likes of Samsung. Google, Apple, and Huawei can be charged to full capacity in less than an hour and a half
What is a quick battery charger?
A quick battery charger is one that can supply the battery with the maximum amount of power it requires to charge in the minimum possible time. For instance, the Apple iPhone 11 models are fast-charged using 18W adapters to get the minimum charge time. Using an adapter that has less than 18W will increase the charge time.
On the other hand, the charge time will almost stay the same if you use an adapter with more than 18W. This is because the charging circuitry was designed to allow a maximum of 18W. If you use an adapter of say 25W, the charging circuit will only allow about 18W to reach the battery. This is done to prevent the battery from being hurt by giving it power that is beyond what it can handle.
When you get the shop or an online store to buy a quick battery charger, it is important to first know the maximum allowable power of your phone or laptop battery. This will help you avoid expenses of buying a charger whose output power is way higher than the maximum input power your phone's charging circuitry accepts. If the power (watts) of the adapter is not indicated, look at its output current (A) and voltage(V), then multiply the two to get the output power.
How can you speed up your battery charger?
- Do any of the fast charging apps work?
- There are lots of android apps that claim to increase the charging speeds of a phone. But technically, there is no way a software app can make an 18W adapter deliver 25W. The apps that claim to boost charging speeds do it mainly using these two methods;
- I.Slowing down the operations of the phone: It is obvious that if you charge a device that has lots of background operations going on, the speed of charging will be affected. This is because some of the charge the battery gets is used to power up these background activities. So, if the app can stop all these activities, the charging speed may improve slightly but not by a significant margin
- Tweaking the charging algorithm: Smartphones have battery charging algorithms within their operating system that regulates the charging speeds of the batteries. That is why most phones reduce the charging speed of the battery when it goes past 50 or 60%. This is because the battery is more likely to heat up when at a higher voltage(charge) than when the voltage is within the normal range (nominal voltage). So, some of these apps may tweak this algorithm (normally in rooted android smartphones) to bypass the charging speed restrictions. However, this is dangerous and could lead to immediate or long-term effects on your battery life.
