Slow charging message on Oneplus charger (tab s5e)

[tibert]

Hello,

I have an Oneplus 8 pro charger, works very well on the OnePlus 8 pro.

When I plug it in the Galaxy Tab s5e it goes from charging by cable, to fast charging, then to slow charging with a message. When I go and see on the Ampere app, it starts at about 1000 mA of charging, then when the message appears it goes down to 80-300.

But I also have a Huawei tablet (mediapad m5), this one if I plug it in, it charges at about 1500 mA.

I tried another cable, which sadly doesn't support fast charging, it charges the tablet at about 1500mA.

I also tried on the OnePlus 8t charger with another cable (this one supports fast charging, but isn't the OnePlus cable), and it was using fast charging, 2000+mA.

So if I understand well this, is that Samsung is blocking through software the OnePlus charger.

Or do you know something else ? Have another idea ?

Thanks.

Interesting article.

Hello,
I tested the cable a bit more, I tried data transfer (calculated about 33MBytes/s with 50MBytes spikes in the task manager), charge on other phones, it works very well. On my OnePlus 8 pro, it charges a 5000+mA. So I don't see why it would be worn out.

Then for the battery charging power, I know about it, this is why I tested multiple times in different orders, and when the tablet was at about 50% battery.

This is why I don't understand the issue that the tab s5e has with the OnePlus cable, when everything else works on it, and no issue with another cable and the same charger.

Best Regards.

Hey there!

That doesn't sound like a worn out cable then - that would suggest that the tablet and charger can't communicate properly with that cable - I'm not sure if OnePlus include any IC chips or anything in their cables, but if so, that might be causing an incompatibility. It's also possible that the charger's trying to use a protocol that the tablet just doesn't support, as your charger is newer than your tablet - however, this wouldn't explain why it works with a third-party cable.

This is certainly a puzzle!! But still, this'll be one to keep under my hat for future experiences.

Best wishes,
Tom
