Throttling Charging Speeds

**Is Samsung Throttling Charging Speeds?**

I’m using the official Super Fast Charger brick and a high-quality cable. However, I’ve noticed something odd. When I first plug in my phone, it shows “Super Fast Charging” for a brief moment, but then switches to “Fast Charging.” 

For example, today I wanted to top off from 90% to 100%, and the estimated charge time was 21 minutes. A 10% charge shouldn’t take that long, right? 

Has anyone else experienced slower-than-expected charging speeds, or is this normal behavior?

I had the same problems. Yes samsung throttle it down drastically when the phone is warm. It sucks. I even went to put the phone outside for a little to get it cold then charge. It fixed it. I have a cable thay reads the charging speeds so I know :hundred_points: its the heat from the phone that's slowing down the charging speed. I get 44 45 with the phone cold and the battery dead. At like 30 40 percent battery you won't get that 45 wat charging speed anymore. Its still fast but the only way u getting the full 45 is like below 40. Or 30. I forgot which one it was but below that. And at normal battery level it maxes oit the charge speed to like 20 percent when its at like 70 percent. Same official sansung charger and cable. 65 watt one

The phone was not even warm when it happened. 20 minutes to charge 10%.
I could see the practicality of protecting the phone if it gets too hot but mine wasn't hot at all.

U may think it's not warm but the stupid phone thinks it is. It does down to the 9wayy charge level when it thinks its warm. Which is very slightly warm. It'll lower.

Yup!

Yeah that's the problem. The heat. It slows it down it only likes when the phone is cool. At complete resting room temp. So basically. U using the phone, especially navi or anything else that makes u use the cpu more makes it a lil warmer. So charging right agyer or during using will slow it a bit. And if heavy usage slows it a lot. If u feel even a lil warm its gonna be slowed. Only whej its cool to the touch I noticed is whej it charges quick. Or if the phone is off. And of course. Its only when the battery is almost dead. Samsung need to do something about this. Good fast charging phone but they dont tell you that it only super fast 2.0 charges when your battery is 0 to 30 percent. Or 40. I think 30. Then slows down a lil. Atill charges quick if not using it and its more even warm. Whej its hot you already kno its gonna be slow. But even slightly warm makes it charge so slow.

Wonder if the larger cooling chamber on the 25U helped this issue?

The newer battery tech with the One Plus, does not seem to have charging issues that I've seen in any reports. Charges super fast.

How about Pixel phones?

Charging speeds are also throttled depending on the battery percentage. At 90%, your phone wasn't charging at the maximum 25/45 watts. This is to help protect the battery.

Good point! Yes, that would be true.
