Hi everyone,

 

Will using 45w charger on Note20 ultra negatively affect its battery health and lifespan?

 

Thank you in advance.

Regards.

@Lounp 

Many thanks for your reply.

 

I bought an additional 45w charger. can I use this 45w charger with Note 20 ultra (25w charging speed) without harming the battery?

 

Thanks

@Lounp Thanks

 

Yes, the 45w charger is Samsung.

 

so using 45w charger with 25w battery (Note20 ultra) wouldn't negatively affect the device or the battery, am I right?

But Note10+ already supported 45w speed.
My question is, can I use 45w charger with Note20 ultra safely?

 

Thanks

As @Lounp has already stated 3 times... yes you can use the 45W charger safely with your Note 20 Ultra.

Thanks to @Lounp 

but the answers weren't clear enough to my case even with N10 + (it already supports 45w charging).

The Note 20 and the Samsung 45w charger support the Power Deliver (USB-C PD) standard. When you connect your Note 20 to the 45W adapter, there will be a bit of a handshake negotiation between the two to determine how much power the phone can support. In the case of the Note 20 Ultra that is 25W, so that 25W is all the power the 45W charger will deliver to your Note 20 Ultra. Therefore you can safely use the 45W charger with your Note 20 Ultra.
