Why my phone battery doesn’t improve after a replacement?

As we have discussed in the previous blog about phone battery quality (refer the link below), a new battery might still don’t improve a lot. Why?

Power: supplier and consumers

In a smartphone, there is power supplier and consumers. Battery is the supplier. All the other parts which connect to the power IC directly or indirectly, are the consumers. For example, screen, camera, speaker, CPU, Hard drive etc are all the consumers. 

Poor battery health or naughty consumers?

If your phone doesn’t last you a whole day, it might be a result of a poor battery. But it might also caused by power consumers, which drain more power than expected.
