At Vapextech we have a plethora of knowledge regarding all manners from batteries. From 9.9v batteries to model batteries or airsoft batteries; our overall knowledge of batteries is all encompassing and unrivaled. 

 

However, there is one battery that arguably garners the most attention. By this we of course the sometimes dreaded mobile phone battery. Although we no longer have such strict covid restrictions compared to this time last year; we are potentially more dependent on phone batteries now more than ever. 

Whilst mobile phone batteries might not share that much in common with say life batteries, or the previously mentioned airsoft batteries, phone batteries are quite interesting devices. 

How Do They Work

Most smartphone batteries work largely the same. Electronic energy is transferred from a phone battery through to the phone which powers the light general power of the phone. 

What Type of Batteries Are Used? 

The most popular types of smartphone batteries used Li-on batteries and Lipo batteries. Li-on batteries are usually the most commonly used phone battery, however, Lipo batteries are often used in the most advanced types of smartphones on the market.

How Do They Charge? 

In terms of how the battery charges, then largely mobile phone batteries charge how normal Li-on and Lipo batteries charge. 

The basics of how a lithium ion battery charges is that the electrolyte carries positively charged lithium ions from the anode to the cathode. In turn, the movement of the charged lithium ions back and forth creates free electrons which creates a charge at the positive current collector. 

The Lipo charging system uses a CC/CV system which stands for constant current and constant voltage respectively. The system will keep the same current rate until that voltage is fully charged and then it will do the reverse for the current system. 

Can You Change a Mobile Phone Battery? 

In conclusion, the answer to this question is yes but there are a few caveats. Some modern mobile phones come fitted with non-removable phone batteries which makes things usually more difficult. 

The name of the previously mentioned battery might be slightly misleading however. The battery can be removed but it usually requires specialist equipment directly from the manufacturer and the battery normally has to be removed by a trained professional. 

Accompanying this is the fact that most batteries are hard to remove as normal anyway. However, you can remove virtually all mobile phone batteries. 

How Do You Know When The Battery Needs Replacing

There are many telltale signs that your phone battery might need replacing. The sign can include, but are not limited to: 

 

  • Battery Overheating- with temperatures set to rise, you might be forgiven for thinking when your phone or battery gets hot it might be simply due to the weather. However,  when your phone starts to overheat, it can be a clear indication that your phone battery needs to be replaced. 
  • Your Battery Is Bulging- whilst you might have to feel if your battery is overheating; you can physically see via aesthetics if your phone battery is starting to bulge out of your phone. 
  • Your Phone Won’t Work If Not Connected To Phone Charger- If your phone won’t even switch on if not connected to a charger, it is more than an apparent inconvenience, it is a worrying sign that your phone battery is starting to die. 
  • Your Phone Just Won’t Charge- Following on nicely from our previous point; if your phone won’t charge at all then you will probably need to replace the battery. It might seem very obvious but in this instance, it really is the case. To put it simply, you will not be able to go on your phone until you get a new battery. 
  • The Battery Dies Quickly In The First Place- On average, a new smartphone battery should last around 5-10 hours on average. If the battery is lasting significantly shorter than this, then it is a good sign the battery is dying.
