If you are using Vivo phone and cannot be activated problem, please observe the device failure phenomenon and solve the problem according to the following corresponding methods:
Scenario 1. The screen does not turn on. lights up when you turn on the phone. The device does not vibrate or react in any way. ?
①Check if the battery is sufficient, charge the device for more than half an hour and try to turn it on again;
②Force restart the device to try to resume use. The operation method is as follows:
< p>Models with Funtouch OS 3.2 and later systems: press and hold the “power button” + “volume down button” at the same time for more of 10 seconds;Press and hold the top round button for more than 10 seconds to force restart the phone (NEX 3 /NEX 3S applicable);
Models with systems before Funtouch OS 3.2: Press and hold the "power button" for more than 12 seconds.
③If the buttons of the device are stuck, dropped or damaged, or liquid has entered, please take the device to vivo official service center for further maintenance.
p>Scenario 2. Press the power button. to turn on or force restart The device vibrates and the screen does not display any image.
If the device vibrates but the screen remains black, it is likely that the screen is malfunctioning. Please take the device to Vivo official service center for further servicing. ?
Scenario 3. An image appears on the screen when you turn on the computer and you cannot access the desktop. ?
① Force restart the device and try to resume use, operation method:
1. Funtouch OS 3.2 and later system models: AppPress and hold “Power Button” + “Volume Up”. Down button” at the same time “More than 10 seconds;
2. Press and hold the top round button for more than 10 seconds to force restart the phone (applicable to NEX 3/NEX 3S <); /p>
3. Machines running systems prior to Funtouch OS 3.2 Type: Press and hold the “power button” for more than 12 seconds.
② Try to repair the system via "System Repair Mode".
Operation method:
First step: When the phone is turned off or restarted, press and hold the “power button” and “volume up button” at the same time for 3 to 10 seconds before the screen turns on. Release the button until the word "FASTBOOT" appears on the screen, then press "Volume -" to move the cursor to "Enter RECOVERY".
Step 2: Find and install the sy softwaresystem>Update to the latest version online>Download the latest version and install it>Connect to available WiFi>Download and install the upgrade package. After successful installation, reboot and try. to resume use.
“Volume +” for about 5 seconds to enter FASTBOOT mode.
NEX 3/NEX 3S: Press and hold the top round button for about 1.5 seconds in shutdown state, then press and hold "Volume +" to enter FASTBOOT mode.
③If the above methods fail to help restore, the customer service center should detect and handle it (customer service center address: enter vivo official website/ vivo mall app--my--service points/after-sales service points--select province and city to request customer service center address) It is recommended to call the customer service center at advance to confirm the questions pertinEntire and understand the working hours before going there, so as not to waste precious time.
How to solve the problem that Pinsheng rechargeable battery is sleeping and cannot be charged?
Slow charging on iPhone 12 will not damage the battery. No research shows that fast charging impacts iPhone battery. Whether you use a 5W charger or a 20W charger, there will be no difference in battery status.
iPhone12 can support PD fast charging protocol. The 20W and 30W fast chargers sold on the official website can charge iPhone12. Estimated full charge time is 1 hour and 30 minutes.
Charging Precautions
The health of iPhone battery is related to the number of charges, which is a complete process of charging and discharging. The battery is fully charged from 0% to. 100%. The process is calledlé a complete charge and discharge.
The main purpose is to charge and play with the phone at the same time. This process has a greater impact on the battery, so it is not recommended for everyone to charge and play at the same time.

Power bank charges empty electricity?
Most of the time, this is the case. The battery is almost dead. Rechargeable batteries, whether rechargeable nickel-metal hydride batteries or lithium batteries, present a maintenance problem.
If the battery is not used for a long time, it should be recharged at a certain interval (about 3 to 4 months for nickel-metal hydride batteries and about 5 to 6 months for nickel-metal hydride batteries lithium). no, the battery will stay there for a long time. If not used, the battery will slowly lose its "activity" and fwill eventually fail completely.
It is estimated that the battery has such a problem. Try to fully charge the battery (a 2500 mAh battery should be charged for 25 hours using a standard charger "standard charge" (slow charge), then discharge the electricity from the battery, charge it fully , then discharge it again, and do this more than three times See if you can reactivate the battery, otherwise you will have to buy a new battery. >Detailed information:
< p>Remarks1 Note that the operating temperature of the battery is between -10 degrees and 55 degrees. Too low a temperature may cause some batteries to be too weak and unable to charge. battery will swell and catch fire, especially 18650 type lithium-ion battery.
2. For normal use, the power can be cut off when fully charged, no need to overcharge.
3. There is no need to do this. Recharge once the energy is used up and charge as you go.
4. Don't obsess about the "first charge" and the "memory effect." Lithium batteries themselves do not have this effect. Just use it normally.
5. Charging should be determined based on the charging current of the charger. Generally, larger capacity chargers have lower charging current and longer charging time, which may cause damage. battery life.
Charging time = battery capacity Current (ma unit).
False power is caused by insufficient charging and insufficient charging until fully charged. Generally, the power bank is slow output. Once fully charged,it must be charged. charged for a while before it is no longer empty. There are also power banks with virtual capacity, but the actual capacity is very small.
There is a “false standard” situation in the power bank, which means that the battery capacity is not as stated by the merchant.
The power bank has a power indicator, but the actual charging and discharging conditions are not consistent, and it is also called "virtual power". This may be because the sensing circuit relies on the sensing voltage to measure capacity, which is inaccurate, and because the increased number of charges and discharges causes the battery's capacity to attenuate at lithium and an increase in internal resistance, detection becomes more and more inaccurate.
The other is the phenomenon of “virtual electricity” whichexists in the battery itself. As long as there is electrical energy in the battery, the battery itself can try to maintain its own nominal physical voltage until it loses it completely. energy. The specific description of this phenomenon is: when the battery is almost completely discharged (the electrical energy is almost exhausted), but there is still a very small amount of electrical energy remaining. At that time, if the battery leaves the working environment (disconnects the circuit), the battery voltage will slowly return to the rated voltage (lithium battery is 3.6V).
Detailed information:
You should also pay attention to the following points when using the battery:
p> 1. After the battery is fully charged, it cannot be left unused for a long time. Used batteries must be fully charged and discharged.stored (used) every one to two months. Otherwise, the activity of lithium ions in the battery will be weakened, which will affect the battery capacity. This may explain why some batteries have shorter charge and discharge times when reused after being left for a long time. 2. Once the battery is exhausted, it cannot be stored without being charged. This will easily cause the battery's lithium ions to lose activity. The lower limit of the voltage of each lithium battery is 1.0 volts. Below this voltage, long-term storage without power will make the battery unable to be charged and used. This may explain why a discharged battery cannot be recharged after a long time. 3. The battery charging time cannot be very long. The activity of the battery charged for a long time will weaken quickly. Encyclopediadie Sogou: Battery drain
