Earlier, there were indeed some rechargeable batteries that required a similar "activation" job. These are the early nickel-cadmium rechargeable batteries and NiMH rechargeable batteries. These batteries produce a phenomenon known as the "memory effect", charging in an incomplete state of discharge, which can easily overcharge the battery, which will cause crystals to grow on the electrode plate for a long time, blocking the contact between the electrolyte and the electrode plate, causing the voltage of the battery to drop, and giving the user the feeling that the battery is running out quickly.

For both types of batteries, periodically, rather than every time, the battery is fully discharged and then recharged, which can mitigate the voltage drop caused by these reasons.

However, most of the batteries used in our mobile phones are lithium-ion batteries. Lithium-ion batteries do not need to be activated by deep charging and discharging when they are first used, because the battery initialization and testing process is already completed at the time the battery is manufactured. Lithium-ion batteries also do not have the so-called "memory effect" and can be recharged at any time.

The suggestion that a full charge and discharge of lithium-ion batteries is recommended on a regular basis is simply to calibrate the fuel gauge on laptops and some high-end smartphones, not because of any benefit to the battery itself. For ordinary mobile phones and digital cameras, which display the approximate battery level in segments, there is no need to charge and discharge them completely on a regular basis.

Charging Tips:

1. Frequent shallow charging and discharging will help prolong the life of the battery than deep charging and discharging, don't think that more charging times will damage the battery, this statement is not applicable to lithium-ion batteries. So, it's a good habit to plug it in when you have the opportunity to charge it, and unplug it when it's almost full – eat small and frequent meals, but don't overeat.

2. The time when the battery is fully charged should be minimized. If you don't unplug the power supply after it is fully charged, it will keep the battery fully charged, although it will not **, but it will accelerate the loss of battery capacity.

Select "Settings" - Privacy "- Factory Reset" without password. If you are still prompted to enter your password, you can enter 1122 to give it a try.

Hello, at present, the record T619+ model mobile phone does not have an initial password, you can directly click on the restore, if you are still prompted to enter the password, it is recommended that you can enter 1122 to try it.

Look inside the settings.

Hello, according to your needs :

1) The bootloader file of the phone is damaged because of a problem with the boot boot.

2) You can enter the recovery mode first, and then do double clearing, and you can generally troubleshoot.
