Is the MP4 charging frequency tomb open?

That's true, some of them are charging in the standby state, the screen doesn't light up, and when it's full, it may light up to prompt.

But I think your problem of not turning off the screen when charging won't have any negative impact on ***.

If you want to fix it, set the screen backlight time to zero in your function menu or turn off the screen backlight (if all of these features are available) before charging

After setting it up like this, if there is a phenomenon that the screen lights up when charging, it means that the system is designed like this at the factory, not your problem, let alone a fault, please don't worry.

There should be a display for charging, right? Turn off the switch to see the display reaction.

It's best to turn off the power first while charging! But it shouldn't make much of a difference.

As long as the output voltage is consistent, it is fine.

When the output voltage is the same, the larger the output current, the faster the charging and the shorter the time; The lower the output current, the slower and longer the charging time. In addition, there are some chargers that can automatically adjust the voltage can also charge MP4, but the charging speed is different.

You can use it, by the way to correct you a mistake Oh, the unit of battery capacity is mAh (milliampere-hour), not milliampere, milliampere is a unit of current. If your charger and MP4 are of reliable quality, it doesn't matter how much output the charger you use, how much current is needed to charge the MP4 will be controlled by yourself, and the actual output of your 5V2A charger may only be a few hundred mAh. If you burn MP4, it means that the MP4 is likely to be a copycat, the charging management circuit has cut corners, and the charger may be that the charger does not have current limit protection, such as the rated output of 500 mAh, the actual output is greater than that, and the result is burned.

When you charge it, see if the charger is very hot, if it's not too hot, it's generally fine.

It depends on whether the output current of the mobile phone charger matches the current of the mp4 charger, if it is big, it will burn out mp4, and if it is small, it will not be charged.

Generally, as long as the joints are the same, there is no major problem.

Do not make calls when turning on and charging**Many people often charge their mobile phones when they encounter no power, for fear of delaying the entry of **. If you do not perform any operation on the mobile phone when it is turned on and charging, it will not affect the life of the mobile phone. However, if you make calls**, text messages, or play games while charging, it will cause harm to your phone, people, and battery.

According to the analysis, the voltage of the mobile phone when charging is higher than that when standby, if the operation is carried out at the same time, the instantaneous voltage of the call or connection to the network will exceed the usual many times, which is easy to damage the sensitive and complicated parts inside the mobile phone, resulting in frequent maintenance of the mobile phone. Secondly, the radiation during charging is also dozens of times that of usual, which will cause damage to the human body. Therefore, when the mobile phone is charged in the power-on state, it is best not to do operations such as receiving calls**.

Nope!! I'm like this a lot!! But don't use your phone if you only have one or two bars of electricity!! The radiation is thousands of times higher than usual!! You pay attention.

There must be a problem. It has an impact on the life of the battery. Causes premature degradation of chemicals in batteries.

It has a certain impact, which will make the chemical reaction inside the battery more intense, resulting in the instability of the battery, which will affect the life of the machine! It's not good for battery machines!

Yes, but according to the machine itself.

I can't be sure about this, but it is recommended not to play while charging, and it is recommended to buy two batteries if you really want to play.

Red screen? Newman's? Send it for repair.

Mobile phone chargers will also do. The landlord bought it in a physical store, right? The brick-and-mortar store is very dark. All the original accessories will be hidden. I'll sell you a bare metal. When you ask for it, he'll say it's not going to be delivered. Ask for money.

Connect your mp4 to the computer.

Hope it helps the landlord.

LR coin cell batteries are generally non-rechargeable, and LR1130 is an alkaline battery. lir coin cell batteries can be charged with voltage. Did the landlord read it wrong?

Hahahaha. Can be charged, however! 40 years ago on the farm, the old farmer's electronic watch did not go and asked me to repair it, so I took off the button electric dry battery, a wooden clip wire, etc., and charged it for half a day, and the electronic watch left.

I used two dry electric charges, and the button battery exploded in an hour, and I couldn't even find all the fragments. After charging for up to two months, usually the old farmer will ask me to help charge every month. The top-up capacity is estimated to be only 10%.

Alkaline zinc-manganese (alkaline manganese) button battery series: AG1 LR621, AG2 LR726, AG3 LR41, AG10 LR1130, AG13 LR44

It cannot be charged. The voltage is. Capacity: 86mAh--- in fact, it is the AG10 used in ordinary "electronic watches".

I can tell you for sure that LR1130, also known as AG10 or L1131, is a button alkaline zinc-manganese battery with a voltage of about 75mAh

The wholesale price is only a few cents, and it is more appropriate to have a large amount, and it is definitely not chargeable;

The voltage for general charging is usually or.

It's clear that no.

I've tried it too. I also opened it to see, but it was a very cup, and I couldn't put it back up.

It's okay to put in a few of this thing, and you can't sell it if you have more,。。 It's better to charge and sell better.

Coin cell batteries are generally not rechargeable and are replaced when they run out. But it can be used for a long time.

LR1130 is an alkaline coin cell battery that generally cannot be recharged, and the voltage is.

I just had this problem, just change the data cable. Because there are two kinds of data cables, one can be used for both data transmission and charging, and the other can only be charged.

1 mp4 is broken, 2 data cables are broken (replace one).
