Is just as fast.
Lithium battery charging is controlled by the chip, you use a 5V2A charger to charge the phone, the phone may reduce this voltage to 3.6V~4.2V, and then connect to the battery, the current will continue to adjust according to the battery situation.
The voltage at the charging USB also allows a certain range of fluctuations, such as 4.5V to 5.5V can be charged.
Thinking about relativity becomes \"you look at a cell phone in a place where time flows fast, and the cell phone charges slowly.\" Changing the charging speed by changing the observation time makes no sense. That is, the clock on which you measure the charging speed should be in the same coordinate system as the phone. And in both experiments, the relative position relationship with the mobile phone remained unchanged, a single variable.
Step back to modify the problem, instead use a charger to charge the high and low chemical batteries.
Does gravity affect the motion of electrons? In classical mechanics, if an electron has a rest mass, it must be affected by gravity.
Do not forget that there are two wires when charging!
If the energy on one line is affected in one way, the other line will be affected in the opposite way, and the two cancel each other out.
How do we prove that they cancel each other out?
Proof:
If the current in one section of the upper and lower wires is large (current is defined as the number of electrons flowing through the cross section of the conductor per unit time), and the current at the other end is small, the electrons flowing out of the charger are not equal to the incoming electrons, resulting in electrons appearing out of thin air, violating the charger cannot create electrons.
If the battery is removed and the wires connected to the battery are short-circuited, electrons will also appear or disappear here. (Saying that although quantum mechanics has come so far now, take energy
out of thin air
Does gravity have an effect on current?
According to the above, it is generally believed that the current must have a loop, so that even if it has an impact, existing instruments can not measure, if it is a one-way current (such as thunder), it will have an impact.
Finally, does the gravity field affect the rate at which the battery is charged? Is battery charging affected in places with strong and weak gravitational fields?
If you want to keep the state of the battery consistent, such as the liquid pressure inside the battery is the same, where the gravity field is strong, the battery needs to do uniform accelerated falling motion, according to the hypothesis of spatial relativity (which is the premise of relativity) no experiment can distinguish between different coordinate systems. The answer is no.
If you consider the pressure inconsistency, this is tied to the battery design, I can't explain.
