I bought a mobile phone on July 4, and the battery given away can only last less than 23 hours, what

It may be that there is a problem with the quality of the battery that was given away.

Lithium-ion batteries have a very bad characteristic, that is, the aging of lithium-ion batteries (or aging, foreigners call aging), that is, after the lithium-ion battery is stored for a period of time, even if it is not recycled, part of its capacity will be permanently lost, because the positive and negative electrode materials of lithium-ion batteries have begun its exhaustion process from the factory. Different temperatures and battery charging states have different aging consequences, the following data are extracted from Ref. [1] and listed as a percentage of capacity:

Storage temperature - 40% state of charge --- 100% state of charge 0 degrees --- 98% (after one year) - 94% (after one year) 25 degrees --- 96% (after one year) - 80% (after one year) 40 degrees --- 85% (after one year) - 65% (after one year) 60 degrees --- 75% (after one year) - 60% (after 3 months) It can be seen that the higher the storage temperature and the fuller the battery charges, the more serious the capacity loss. Therefore, it is not recommended to store lithium-ion batteries for a long time, on the contrary, manufacturers should treat them like rotten food. Users should pay close attention to the production date of the battery.

It is highly likely that the merchant is shoddy.

A lot of J commercial fake batteries have been replaced with real original ones as giveaways1

How many **s did you hit on this day?

Don't look at it, the batteries that are generally sent are not foreign originals, if the original batteries are sent, then they will be specifically explained, and generally only the models above the mid-to-high-end can send the original batteries. As for the domestic battery you don't have too much hope, can be used for a few days is a few days, the quality of the domestic battery is very poor, don't believe you use to try, the domestic battery charging time is often bulging, put the phone not to turn on may be a contact problem, maybe the battery inside the problem itself, this is the need for you to customer service to test it, as long as the shape of the battery is not obviously deformed, then ** is unlikely, unless overheating will occur under special conditions**, Because your phone is a branded phone, this is unlikely to happen.

Since you think that it doesn't matter how long the battery you send lasts, then don't use it and solve everything, what else is there to worry about?

Yes, if you say the top thing, it's because the TV is not original, so the size is different, and this kind of commercial battery can play about 90% of the normal battery, which is still good.

In terms of safety, rest assured that the battery is in poor contact with the mobile phone, and it is recommended that you do not use this battery, troublesome.

One piece is original, one piece is a gift! Most of the free charges can be turned on!

Try changing the charger.

If not, it is estimated that it will be garbage.

This is normal.

Mine was thrown away in a month.

I look for the one who sends the battery to buy. Generally, brand machines are not sent.

Don't buy it, go to another store to buy it.

I'm sick... How can there be a good battery...

Tianyu mobile phone battery is the most used If you want a good signal to buy Nokia.

The Apple phone is also good, the photo is quite clear, and the image is more clear.

Only Nokia Intelligence knows best.

I bought a copycat machine with a screen, and the general battery still has to be used for about 5 days, if you want to have a long standby time, then buy a screen, and the standby time should be managed for 10-15 days! The length of standby time has a lot to do with your own use.

If there is a rotten place, throw it away, if it is a little yellow, it proves that the temperature of the phone is too high, and it will be good to rest, so you don't need to throw it away.

Or use the original one, this thing will be broken if you don't use it for a long time, it is recommended to use the original one, and the other piece is used as a backup, so it can only be so.

Use it every half a month or a month, and then put it there on a full charge.

It's best to use it for about three months and then fully charge. If you don't use it for a long time, the battery will also run out.

What does it have to do with the battery?

There are several types of batteries, okay. Medium and bad, bad!

For the sake of profit, the seller is definitely reluctant to send a good one! It must be a battery that is worse than the original electricity! That's mainly a matter of the seller's character! It has nothing to do with the battery!

There are also good sellers who send batteries, which are not inferior to the original ones! The key is how your seller is!

Hope it helps!

The things sent must not be compared with the original, buy a better one yourself, recommend your domestic Hongyi battery, very good.

Don't be so picky about what you give away for free.

Don't count on what you send.
