Charging speed doubts.

[AjayCA]

Dude, 1 doubt I have, Galaxy S21 ultra has 5k mAh battery and supports 25 watt fast charging. Galaxy A72 also has 5k mAh battery and also supports 25 watt fast charging.

But, Galaxy S21 ultra comples 0% to 100% in 1 hour and Galaxy A72 comples the same in 1 hour 20 minutes. Why?🤔

[DarshanChatterjee]

Processor.

S10 lite vs A71 if you see. Both are same. Battery and charger. But S10 lite gives better battery backup and charging speed as compared to A71. Only because of the processor and how Samsung optimized it.

I doubt it. Because, processor and optimization can be considered only if the mobile is turned on. But, the charging test was checked with both the mobiles powered off.

The software also controls charging and the circuit in it aswell.
Both have got entirely different circuits (hardware).

BOTH HAVEN'T SAME PROCESSOR
CHARGING SPEED ALSO DEPENDING ON PROCESSOR AND SOFTWARE ALSO !

[AjayCA]

If the test is done with power off mode, then processor and software can't be considered.

[AjayCA]

On Bricking the device, with no software also, you can charge fully.

[AlphaTrion]

A smarphone storage has many partitions in it.
Charging is controlled by kernel (present inside boot partition), not system partition.

The kernel of both devices have got entirely different drivers due to different hardwares.

See if you have these 2 settings on and compare them.

This is what Galaxy A72 has
