Redmi Note newly bought, how to use it, the battery can be good?

Hi! Xiaomi phones and Redmi phones use lithium-ion polymer batteries.

Essential knowledge of battery charging].

1. The lithium battery does not need to be activated, it can be fully charged, and it does not need to be full for 12 hours;

2. Lithium battery has no memory effect, and should be charged in time when the mobile phone is too low;

3. Overcharge and overdischarge cause great damage to the battery;

4. Try to choose the original charger to avoid irreversible consequences. Proper charging can effectively extend battery life.

You bought red rice. The machine is not good.

Redmi Note5 features:

Processor. The Redmi Note 5 is powered by a Qualcomm Snapdragon 636 octa-core processor, which is made using a 14nm process and can reach a maximum frequency of gigahertz. It is also equipped with an Adreno509 graphics processor.

Camera. The Redmi Note 5 is equipped with a 1200+5 million pixel dual camera on the rear. The 5-megapixel camera is mainly used to capture depth-of-field information, and the 12-megapixel main camera has dual PD dual-core focus.

The Redmi Note 5 uses the MIUI 9 operating system and supports full-screen gestures. Swipe up from the bottom to return to the desktop, swipe up pause to enter the multitasking interface, and swipe the left and right edges of the screen inward to return to the previous level.

Hi! Do you use photovoltaics?

1.Please remove the battery for 5 minutes, put it in and connect the computer and mobile phone with a data cable for 30 minutes, and try to turn it on again.

2.If it still can't turn on, please try to back up your data and try to enter recovery mode (power off and press and hold the volume up + power on button) or fastboot mode (power off and press and hold the volume down + power on key + meter key) to flash the computer.

Please follow the flashing tutorial to flash the machine, and the sixth way is line brushing. Address.

Sister's ......My indicator light is on, and the charge is getting less and less.

It can be charged, but it is not recommended to use a universal charge.

Universal charging has good compatibility, but in order to produce qualified products, special computing chips and testing circuits must be used, and the comprehensive cost of such products is not 100 yuan, don't want to win. What new technology does the "universal mobile phone charger" that sells for dozens of yuan (the actual cost probably less than 10 yuan) use to automatically provide the appropriate current and suitable threshold voltage according to different batteries, so as to achieve universal efficacy? It's really suspicious, and a closer look at the "universal phone charger" shows that it only has two output wires, while we know that a well-designed charger has at least three outputs. The two in the middle of the battery are generally data feedback lines and temperature and alarm lines, and most lithium-ion batteries have protection circuits and even intelligent management chips inside. "Only two output lines" means that the charger has given up the protection circuitry that the battery itself has.

Only in this way can the "cheap omnipotence" be realized

Many chargers with low manufacturing accuracy use the method of lowering the cut-off voltage (the normal cut-off voltage is . They set the threshold normal distribution to about 4V. Doing so makes the charging itself safe, but the battery is never fully charged.

This is equivalent to a decrease in battery capacity, which leads to an increase in the number of charges, which also leads to a reduction in battery life.

Lithium-ion batteries are very squeamish and sensitive. The charging and absorption efficiency of lithium-ion batteries is almost 100%, and whether it is overcharging at a high current or overcharging at a small current, it can cause the battery to fail. Therefore, battery threshold control can be said to be the key to charging control, in summary, when the battery capacity of smartphones is generally large and expensive, it is not recommended to use universal charging.

Yes, but the universal charge is very harmful to the battery and will seriously reduce the battery life. It is recommended to use a dedicated dock charger.

1.The universal charger on the phone battery is damaged by :

2.The charging current of the universal charger is small, only about 100mA on average, imagine an 800mAh battery to charge for 8 hours;

3.The charging current of the universal charger is unstable, and in order to reduce the cost, the universal charger only uses a very poor capacitor to filter, and the current ripple is very large;

4.It is also the most critical that the charging voltage is not accurate. For standard chargers, the charging limit voltage is no more than 1%, while the universal charger can be charged, or even higher, which is the most harmful to the battery.

It's not that you can't, occasionally you can charge it with a universal charger. It is not recommended to use it often, it is recommended to use the original charger to charge the phone.

1.It does not need to be fully charged for 12 hours, the lithium battery can be charged as you go, it is recommended that you disconnect the power supply after it is fully charged.

2.It is best to turn it off and charge.

3.Try not to drain the battery and turn off the phone automatically, over-discharging may cause the battery to sleep.

4.If you do not use the battery for a long time, please store it in a dry and low temperature environment.

Hello,At the bottom of the Redmi note is the charging port,In the case where you can take the case away,Take it away and you will see the battery。

The third item is battery comparison.

1. Redmi Note has a large inch screen, which is larger than the inch Redmi mobile phone and Redmi 1S telecom version, and is more popular with large-screen users; The Redmi Note is about 13 mm longer than the Redmi and Redmi 1SS phones, nearly the length of a thumb, and about 5 mm wider to fit a ballpoint pen. It's worth mentioning that the bezels of the Redmi Note are slightly narrower than those of the Redmi, but they're still wide.

2. Xiaomi Redmi Note mobile phone is equipped with Lianke Fax Zhen octa-core processor, which is stronger than the previous Lianke Fax four-core Redmi mobile phone; However, the Redmi 1s telecom version of the mobile phone equipped with Qualcomm quad-core processor is still comparable to the Redmi Note in terms of performance.

3. Redmi Note has been upgraded to a front 5 million rear 13 million pixel camera, which is better than the front 1.3 million rear 8 million pixels of Redmi mobile phones and the front 1.6 million rear 8 million pixels of Redmi 1s telecom version of the mobile phone;

4. Xiaomi Redmi Note mobile phone uses a 3200mAh large-capacity battery, which is more outstanding than the 2000mAh capacity battery built into the Redmi mobile phone and Redmi 1S.

5. The standard version of Xiaomi Redmi Note mobile phone has a memory combination of 1GB RAM+8GB storage space, and the enhanced version memory combination is 2GB RAM+16GB storage space. The memory combination of the Redmi phone is 1GB RAM+4GB storage space, and the memory combination of the Redmi 1S telecom version of the phone is 1GB RAM+8GB storage space, and the Redmi Note has more outstanding performance and faster running speed.

The difference is the size, and the capacity, everything else is the same.
