Xiaomi introduced a series of current best phones for the Chinese market back in July. It consists of three models – Xiaomi 12S, xiaomi 12s pro a Xiaomi 12S Ultra. Unfortunately, these models are not available in the global version. According to the latest leaks, the company is focusing the most attention on the models of the Xiaomi 13 series and Redmi Note 12 that have already passed certification.
Xiaomi 13 a Redmi Note 12 have already passed certification
Smartphones of the new flagship series from Xiaomi along with news from Redmi have passed certification. Upcoming Xiaomi devices with model numbers 2210132G and 2210133G have been spotted on the EEC certification, likely belonging to the Xiaomi 13 series flagship phones.
Furthermore, two new phones were spotted in a separate EEC listing Redmi with model numbers 22101316G and 22101316UG. The letter "G" at the end of the model numbers could represent global models. Xiaomi phones and others Redmi were registered under Xiaomi Communications. However, the certification does not provide further detailed information.
Xiaomi 13 will have Snapdragon 8 Gen 2 and 100 W charging
According to the information leaked so far, the new Xioami 13 series should receive a processor from Qualcomm, specifically Snapdragon 8 Gen2. The introduction of this processor is planned already this year in November. The introduction of the Xiaomi 13 series should take place later this year, but it should make its debut at the beginning of next year.
Other information indicates that the new Xiaomi 13 series will have a single-cell battery and support 100 W fast cable charging. In the case of wireless charging, the speed should reach 50 W. The presence of a chip is also expected Surge P1, which is currently the only one on the market that supports 100 W single-cell charging.
Redmi Note 12 in a few months
As for the series Redmi Note 12, detailed information regarding the specification has not yet been published anywhere. However, the Note 12 series is expected to be introduced in the Chinese market around October this year.

100 W single cell charging:
since li-ion monocells have a nominal voltage of 3,6V (max. charged without charging, or the charging voltage is 4,20-4,25V), so also in the case of the latter, this means that the electronics in the mobile phone must ensure that the battery THEORETICALLY brutal surge 100W/4,2V = almost 24A!
theoretically because the practical maximum (also only at the peak at the beginning of charging an empty battery) is around 67-70% of this value, i.e. in practice the battery should never receive more than approx. 16,5-17A (at a low charge ) and next, as the charging approaches 100%, the charging current will also decrease accordingly (copying the charging curve), even at the end only to hundreds of mA (I would be really curious what the AccuBattery program would show at the very beginning of charging an empty battery)
AVSAK: the start of charging at 17 A and the rough-roughly-averaged charging current during the entire charging (ie from 0% to 100%) should be approx. 10,5 A (ie 10,5A x approx. 4V = approx. 42W is the next approx. coarse-averaged charging current during the entire charging period)
5000 mAh battery (approx. 5 Ah * 3,7 V = 18,5 Wh if we consider 3,7 V nominal voltage) with the so-called "100W charging", charges in approx. 18,5Wh/42W = 0,44h = approx. 26 and a half minutes
otherwise, the irony is that x-watt charging will NEVER, NEVER, NEVER, NEVER, NEVER, NEVER, NEVER reach the charging power of x watts. at the beginning in the peak it is 67-70% of this value, rough-rough-average during the entire charge is 42-44% of the value x
and why is it not 100% of the x value even at the beginning in the peak? because in our universe the laws of thermodynamics apply and 100% efficiency does not exist, always some energy (during energy conversions) must be transformed into the form of waste heat
and after other conversions of currents and voltages and so on, they lose even more shares of energy (e.g. put the 100W adapter in the cable, let's give it 5A at 20V... hahaha if there is a cable that can actually carry 5A, even most quality cables for charging are made for max. 3A ... but simply whether the 100W will go through the cable as 5A at 20V or 3A at 33V is irrelevant, the important thing is that even from the adapter to the mobile phone, 100W will not go through the cable, but only 80-90W, because thermodynamics) ... next, the internal electronics of the phone must convert those cable 5A at 20V or 3A at 33V (in real life 80-90% of that value, ie 80-90W) to some 17A at 4,2-4,25V (ie again there were losses, because we only have approx. 17A* 4,2V=70 watts and that too only at the start of charging at 0% battery charge)
AVSAK: starting charging current of almost 17A which is charged to the battery, thank you, no please - this is absolute madness
