Samsung Galaxy S21 Ultra 5G Battery Super Fast Charging Test 0% to 100% | 25W Super Fast Charger By Android Doctor

Yo, it's you by the android doctor back again with another video okay. So I'm here with my brand new Samsung Galaxy s21, ultra okay, so in this video I'll be doing a battery charging speed test. So I have a 25 watt superfast charging charger. So this is 25 watts, it's the original charger and also the original cable. And at the moment my battery is totally dead. As you can see, it's on zero percent, okay, so I'm just going to plug in my charger.

Okay, so it's plugged in okay! So I've got my watch here, so I'm just going to start it and every 10 minutes I'm going to come back guys, and we're going to see how far the battery percentage has reached so see you all soon guys, okay, guys, so we're almost at the 10-minute mark, and we've got 11. Okay, so doing the math. Roughly, that's telling me that you're going to get about 10 every 10 minutes, okay, so I'll be back at the 20-minute mark guys, okay, guys, so we're almost at the 20-minute mark. So let's have a look and see how far it's reached. Let's just wait for it to get to 20 minutes, okay, so it's on 28, okay, so it seems as if it's speeding up now the charging speed.

Okay, I was expecting it to be at 20 because from zero to 10 it took 10 minutes. So I was expecting from 10 10 to 20. It would have taken 20 minutes, but it's actually gone up to 28, so we've gained an extra eight percent within those extra 10 minutes, so um I'll be back at 30 guys. I mean 30 minutes I'll, be back at the 30 minutes mark and see how far it's reached see you soon. Okay, guys we're almost at the 30-minute mark, and we have 46 so from a totally dead battery at zero percent within 30 minutes.

You will get 47 of battery power. Okay, so I'll see you guys at the 40-minute mark see you all soon: okay, guys back again we're almost at the 40-minute mark. Okay, let's have a look okay, so at 40 minutes from a dead battery at zero percent, you're going to get 64 battery power. Okay, so I'm guessing it's roughly gonna. Take about an hour to get a full charge unless some super-duper fast.

Charging power kicks in okay, guys, so I'll, be back at the 50-minute mark, and we'll see how far the battery has reached. See you all soon. Okay, guys we're almost at the 50-minute mark okay, so at 50 minutes for battery percentage is at 80, okay guys. So I will be back at 60 minutes, and we will see if we have a full battery, see you all soon. Okay, guys we're almost at the 60-minute mark so one hour guys, let's have a look and see how far it's reached 88 percent, so it's not quite fully charged yet, so I will be back in the next 10 minutes.

See you all soon: okay, guys we're at the one hour 10 minutes mark and the battery percentage is at 93 percent. So it seems to have slowed down towards the end once it touches the 90. The charging speed seems to have slowed down. Okay, so I'll be back in another 10 minutes, okay, okay, guys! So back again, it seems like some type of turboboost has kicked in because it's just jumped to 99 within those three minutes. So when it gets to 90 guys it's going to slow down the download speed.

Okay, let's stop it. So it's took one hour and 40 minutes from zero percent to get to 100 so like I was saying guys when it gets to 90 it's going to slow down and then when it gets to 92 percent, it's gonna start to speed up again, but between 90 and 92. It really does slow down, not sure why that is but um once it gets to 92 it's gonna speed up, and it's going to get to a hundred percent within a matter of minutes. So yeah guys. This was my video just testing out the charging speed on the Samsung Galaxy s21 ultra um do bear in mind that this device has a 5 000 William hour battery, so um it does have a lot of charging to do, but that's really not that bad one hour and 40 minutes from a totally dead battery to get to 100 a full battery.

That's pretty good! In my eyes, but do remember, you can also upgrade your charger to a 45 watt charger. If you want to um charge the phone a lot quicker. Let me just show you all that this is the original Samsung superfast come on focus camera. Oh, gosh come on focus, I don't know if you can all see that by Samsung, but is the superfast charger there? It is superfast charger, so yeah guys this was just my video be sure to give it a thumbs up. Share the video.

It's your boy, the android doctor, and I'm out deuces.
