Charging protocol supported by S15 mobile phone: vivo flash charge: up to 66W (11V/6A 11V 5A/4A/3A) Ordinary charging: 10W (5V2A) vivo wireless charging: does not support Qi wireless charging: does not support reverse charging: does not support wireless, wired support.
The Redmi K40 is non-removable with 4520 mah capacityBattery, support for fast charging (33 watts fast charging, support QC3 /PD0 fast charging protocol).
WFlashCharge flash charging technology, equipped with exclusive independent efficient charge pump and FFC charging algorithm optimization, greatly improve the full charge speed, making the mobile phone heat lower, charging faster, giving you a very excellent charging experience. FlashCharge flash charging technology can only support its own high-power private charging protocol, at least 66W certainly does not support PD's 65W.
The s15 has a 4500mAh battery capacity. vivoS15 built-in 4500 mah capacity battery, support 66 watts flash charge, starting from 1% charge, charging 10 minutes can charge to 36%, 49 minutes can fully charge the phone. Support OTG reverse charging, theoretical standby time: theoretical 4G single card standby time: up to 17 days; Theoretical 4GVolte call duration: up to 18 hours.
The s15 does not support wireless charging. vivoS15 is a mobile phone released by vivo on May 19, 2022, because the device is not equipped with wireless charging accessories, it does not support wireless charging. If you want to charge, you have to go throughWireless charger.
If it refers to the models that vivo supports wireless charging, the devices that vivo/iQOO currently supports wireless charging are: X90 Pro, X90 Pro, X Fold, iQOO 10 Pro, X80 Pro Snapdragon, X80 Pro Guet, X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro.
There are many mobile phones that support wireless charging, mainly including the following categories: Apple series mobile phones Apple has launched iPSince hone, some high-end models have supported wireless charging. For example, the iPhone XS, iPhone XR, iPhone 11 and iPhone 12 all support wireless charging technology. Apple's own AirPods wireless chargers also work with these phones.
Huawei P40Pro supports 40W Super fast charge, 27W wireless fast charge, and wireless reverse charge. Huawei P30Pro supports 40W super fast charge and 15W wireless fast charge. Huawei Mate30Pro phone supports up to 10V / 4A super fast charge, bothCapacity 4.5V / 5A or 5V / 4.5A super fast charge, compatible with 9V / 2A fast charge. The phone also supports 27W Huawei Wireless Super Fast charge and wireless reverse charging.
A large lightning represents 27W and above power, a large and small lightning indicates that the charging power at this time is 15W, if a small lightning is displayed, it represents the wireless charging power below 15W. When the mobile phone is detected to be in a charging state for a long time in the recent period, in order to protect the battery, the intelligent charging mode will control the battery to a certain proportion of electricity and stop charging. To recoverCharge to 100%, simply reduce long-term charging behavior or turn off smart charging mode.
Wireless flash charge mobile phones have a plus 8pro, Honor V30 pro, Samsung S Meizu 17pro, nuts pro3, etc., but in the mobile phone industry wireless flash charge should actually be called wireless fast charge, the two will be slightly different. At present, there are more models that support wireless fast charging, but there is no support for wireless flash charging, flash charging and fast charging are not the same concept.The reason for wireless flash fire is that it can facilitate people's lives, realize the idea of charging people at any time, and it is more energy-savingGuarantee, meet the wireless flash charging and wireless backcharging what means people's desire for a low-carbon life. Of course, there are drawbacks, when people in relatively remote areas it is difficult to accept the wireless signal everywhere, once used to this mode, it will also cause no electricity to charge the phenomenon.
1, W wired super flash charge Wireless flash charge and wireless reverse charge What is the meaning : this flagship level
2, Mi 9 pro 40W wired flash charge 5 minutes to charge 20%, 48 minutes full 4000mAh battery; 30W wireless flash charge only takes 25 minutes to charge half of the 4000mAh battery and 65 minutes to full; 10W wireless backcharging supports wireless charging for iPhone, 10 minutes can charge 7% for iPhone xs, provide 55 minutes of call life, and can also charge headphones, toothbrushes, shavers and other products that support wireless charging.
3, more importantly, Mi 9 Pro 5G supports 40W wired charging, 30W super wireless flash charging and 10W reverse wireless charging. Under the 30W super wireless flash charge, the Mi 9 Pro 5G is charged 50% in 25 minutes and 100% in 69 minutes.
4, the next is 30W wireless super flash charge, millet once again refreshed the efficiency of wireless charging. Just a gentle release, 25 minutes can be half charged for 4000mAh battery, in the 5G era, the convenience of wireless charging will be more prominent, and truly realize the practical anytime and anywhereCharge up.
1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
2, wireless charging is also known as inductive charging, non-contactInductive charging, derived from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
3, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side by the wireProximity to the magnetic field generates an electric current that charges the phone. As shown below.
4, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
5, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" each otherSensing and forming an electric current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
6, the basic principle: The use of electromagnetic induction, that is, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
