Charging speed

[warlord420]

I would not worry about quick charge killing your battery.
Used quick charge in my car, and at home, and portable battery pack on my Zenfone 2 for 1.5 years , I couldnt tell you if there is a difference from day one. That phone lasted daily from day one. Made me regret buying all those QC devices actually. Only reason why I retired it is how painfully slow the camera was and I got bored of it.

Hello
Question: is QC3 a killer of battery? Is charging at low amp better, or...? Cuz I read here and there that it's still better to use a slow speed charging device so that the battery doesn't heat up and doesn't wear off too fast.
What are your thoughts about that?

For Maximum life battery should be kept between %20 and %80 at all times. Quick Charge has a logic chip which slows down the rate of charging after %80 so QC impact on battery life is minimal. Best thing yo can do to maximize battery life is to make a habit of plugging it in before going to sleep

My Axon 7 USA version took sweet 1 hr 30 min to charge from 0 to 100%
In between I had 5 to 7 mins on screen with whatsapp chat and 2 mins whatsapp call.
I got this mobile 3 days back..
Is this the typical charge time or is my device defective?

Hello,
From 0 to 100%, 1h30 to charge is pretty fast and I think totally normal. Like thohac said, the charger slows down the charge after 80%, so it's really fast from 0% to 80% and then "normal" charge after.
QC3.0 is really nice, you have 60% of battery in about half an hour.
Oh, don't go lower than 10% with the phone. Below that you might brick your battery, and you won't be able to charge it anymore.

Thanks for the suggestion..
I was scared if it was defective..
I'll never got below 10% as u said.
Thank you

I use Ampere to test my charge speed. And use any cable and power supply which Google employee Benson Leung tests as compatible with USB-C specs (link to a spreadsheet someone on Reddit keeps up-to-date with Benson's tests). Benson is well known in the Android community because he leaves comments on chargers and cables he buys on Amazon of his test results and the press coverage and fixes vendors do to get their act together.

So far, the speeds I've seen on various charging technologies over the years are around 500mA, then 1000mA and with a proper USB-C cable and charger around 3000+mA.

That should cover all of the charging knowledge you need

I measured some different charge cycles. I get approximately 50% charge in 40 minutes. I noticed that the battery charges faster when it is initially low (15-30%) but takes exponentially longer to fill once it's reached >85%. I'll try to post an update with a detailed log of the times and charge levels.

This is the way QC3 works. It charges full speed till the battery reaches 80% then it charges normal speed till it's full.

What's the charging mA that you guys are getting at Ampere? Mine is showing 1700 mA with the default charger. Is that ok for quick charge?

It is once your battery is like 75 or 80% full. If it´s at say 50, it should be closer to 3000.

Thanks, so definitely something is wrong, I am getting max 1700mA at 30%, I will ask for a replacement.

How long does the entire charging process take?

Yep that's the way mine works too. I don't use the original charger, I bought 2 Aukey QC3.0 chargers, and it's around 2700-3000mAh till 80%. Then it goes down to 2000 I think.

Thanks for the replies nupi, I am not sure, this is my 4th day with it, I will try to measure it.
Now with 75% I am getting max 880mA, with original cable and charger.

@nupi I measured the charging today, it went from 9% to 100% in 2h 32m, I am not sure if this is ideal for quick charge 3, what do you guys think?

Very slow. Using a 2amp charger does it in about 2hr with no quick charge.

I'd say something is wrong.

i'm using A2017G B08
i have noticed inaccuracy with my battery indicator
when i'm charging (quick/normal charge) yhe battery level increased very slowly
a reboot is needed to display the correct battery level all the time
anybody experienced similar bug/problem? any potential solution?

 

[LifeSupportZ]

with QC3.0 this device charges pretty fast and i really have no complains with charging

I did and turned out to be hardware fault. I had to RMA it.
