Why does the battery of some smartphones get drained quickly

[neku]

I am using various smartphone for testing apps, and I find that the battery of only some smartphones is getting drained quickly with some apps. For example the battery for Redmi A1, A2 does not get drained quickly, while other smartphones battery is getting drained very quickly. What is the reason for the difference in battery life?

From what I understand, the battery of each smartphones can never be the same especially if they are from different products. Then again I believe the processor and software have also have a role to play as well.

Batteries have different capacities, you don't expect 600mph to last like 12000mph. Secondly, the phone mechanism and functionality plays a role in how the phone uses enegy.

My present smartphone is almost new with one year warranty but it's battery is causing problems as it required to be charge so many times a day. People say as to never charge battery when it is on 90 or more.

As for me, I have already adapted to the fact that I am expecting an average performance from my Redmi battery. It is almost two years old now and the battery starts shortening in it's battery life.

The standard battery should be at least 5000 Mah to avoid draining quickly. If lower, better to avoid running heavy apps, like certain games that consume too many resources.

The difference in battery life between smartphones can be due to several factors. First, the hardware of each device plays a crucial role; More efficient processors and higher capacity batteries can offer better performance. Additionally, the operating system and apps optimized for each device can affect power consumption. Some apps may be more resource-intensive, draining your battery more quickly. There are also screen brightness settings to consider, connectivity (such as Wi-Fi or mobile data), and the use of features such as GPS, which can consume a lot of power. Finally, the age of the battery and its state of health can influence how it retains charge. Now do you understand why this happens?

Yes some would tell you once it gets to 80% you don't need to charge it any longer. If you phone is still new you shouldn't be having battery issues. What phone are you using?
