Samsung a7 2018 slow charging

[maxim123]

How far are you running the battery down to?

It was 64% when I charged yesterday. The previous one where it charged 1% in 2 mins was when I ran the battery down to 44% I think (not sure exactly)

Is it charging any better?

Hi, sorry I have been a bit busy with works that I forgot to check. I remembered when I charged my mobile yesterday. It charged 10% in 11 minutes (I charged when it was about 49% I think). but when it charged to 79%, I had to use the mobile, then I charged it again and it charged slow like before, what problem is this?

Newer systems will charge fast until they reach about 80 percent then the charge slow to prevent damage happening to the battery.

Thank you for the reply. It should be that I guess charging fast when the battery goes low and slow in higher level.

Any updates?

Any updates?

I don’t know what is going on. Sometimes it charges fast and sometimes it charges at the previous speed (at lower levels)

Ok… @Rustys

I think it was indeed like the salesguy said, it should improve after few times. I charged it yesterday and checked it was about 1% in 2 mins, should improve as it continues since it is improving right now.

Has it improved?

I don’t use mobile much so I don’t charge much. But I charge again today and it charged 10% in 30 mins, slowed down to previous speed.

When it slowed down what percent was it at?

It will reduce the charge rate to a slower one at or about 70-80 percent to prevent battery damage.

That is correct

With out know what percents you are charging to and what it is charging at can not state since you are leaving out that information.

Suggest that you talk to the stores tech and have them diagnose the system while you wait.

Therefore, fast charging technologies are most effective when your battery is less than 50 percent full, but have little to no effect as you pass 80 percent.

Finally, the amount of voltage and current passed to the battery is controlled via a charge controller circuit inside the phone. Coupled with temperature and voltage sensors, the controller can manage the amount of current to optimize the battery’s charge speed and long-term health.

I see. Yeah there is sometimes fast speed and sometimes low speed. I haven’t noticed any problems with the rate of battery consumption so it should be okay for now I guess.
Thank you all very much . You can mark this as solved.[/color]

Not a problem glad we got it sorted.
