Mobile devices

I need to buy a battery for iphone 4 (just the fourth one).
1) How is the original battery for iphone 4 different from the copy?
2) Is there a noticeable difference in work between them (duration of work, etc.)?
3) Is it really necessary to take the original battery?
Now the same questions, but concerning the charger for iphone 4 (cable and power supply):
4) How is the original different from the copy?
5) Is it really necessary to take the original?

Answer 1

My advice: the battery is only original, and the charger is of any quality.
There may be a bad capacity, there may be an incorrect voltage, it may overheat during charging and explode, it may simply swell in a month.

2) Is there a noticeable difference in work between them (duration of work, etc.)?

Yes, it depends on the quality.

3) Is it really necessary to take the original battery?

Yes.

4) What is the difference between original and copy?

Low current, unstable operation, etc.

5) Is it really necessary to take the original?

No, but you need to take a quality device.

Answer 2

1) How is the original battery for iphone 4 different from the copy?

As mentioned above, by the capacity of the battery, bloating rarely occurs (I put a copy of the battery from aliexpress on 3 iPhones. It works fine for 2, it didn’t work for 1 (the contact turned out to be damaged, I threw it away))

2) Is there a noticeable difference in work between them (duration of work, etc.)?

Answer 3

for example, Akum have a habit, especially low-quality ones, to swell, while they will break your case / screen / board, etc., perhaps all together at once
