iPhone 13 Charge Test: 20W vs 12W vs 5W (Apple)



Note: There appears to be some confusion based on what I said about Optimized Battery Charging at the start of this video. I recommend leaving Optimized Battery Charging ON to preserve you’re iPhone’s battery heath as much as possible. The only reason I turned it off in this video was to create the most accurate test environment possible for comparing these three charging methods to one another.

  1. Hey guys, there appears to be some confusion based on what I said about Optimized Battery Charging at the start of this video. I recommend leaving Optimized Battery Charging ON to preserve you’re iPhone’s battery heath as much as possible. The only reason I turned it off in this video was to create the most accurate test environment possible for comparing these three charging methods to one another.

  2. Normally I just use 10W wireless charger on my 13 pro max every two days but when I have low charge and need to charge somewhat fast I put it to 20W apple charger just so I survive the day.

  3. Charging your device up to 80-100% regularly reduces batterylife. IPhones and IPads (don’t know about other Apple devices) have a feature, that reduces the charging speed at 80-90% and again at 90-100 to extend Batterylife. Thats why in the end the 12W catches up to the 20W.

  4. I charge off of a 5w for the same reason but I have a USB-C cable plugged in to my Mac, which charges at 12w if I'm right and I use that if I need a quicker charge.

  5. I have a 13pro and also use a 5w at night or a slow wireless charger for battery longevity as well. I use a anker nano 20w or my iPad Pro charger for when I need a quick charger before I go out for an evening or need a quick bump.

  6. 5w: what what what what what
    15w: what what what what what what what what what what what what what what what
    20w: what what what what what what what what what what what what what what what what what what what what

  7. I just bought an iPhone 13 (regular) last week, and they had me buy the 20W brick. I had an iPhone 7, so I have a 5W brick. I like the fact I can use the 5W, for overnight charging while I sleep, or using it in the car, since the 20W does not have a USB for that. Thank you for posting and comparing.

  8. Idk how it took over 2 hours to charge your phone I have mine fully charged 0-100% in like an hour 40 mins with a 20 watt charger and like an hour 35 with a 30 watt charger I do miss my Galaxy s21 plus 0-100 in about an hour

  9. I’ve always charged my iPhone XS with the 12w brick that came with my iPad. I usually do it overnight even tho you’re not supposed to with a higher wattage charger. My battery health is 78% after 4 years

  10. What’s funny is ever since I disabled Optimized Battery Charging last February my iPhone XS hasn’t dropped from 84% battery health in almost a year

  11. "The lower the wattage the better it is for battery health"
    Unfortunately, that's not always the case. Depending on battery chemistry, low current charging can cause some unwanted side effects like hard to break structures building up, memory effects, etc. Moreover, very slow charging can mess up with the charging controller and cause improper charging — either consistently under or overcharging. In both cases this can lead to reduced battery life. The software that is supposed to monitor your battery charging and help prolong battery life can also have trouble working correctly. Do remember that the device, charger and software are all designed and tested for a normal user that uses recommended or similar charger.
    I think it is always best to follow manufacturer's guidance. It probably is ok to charge at half the current, but I would probably not want to go much lower than that.

  12. I like keeping my phone battery between 30 and 80 percent. That way, I can really take advantage of my 20 watt charger as it charges faster between those ranges. Keeping it between 30 and 80 also increases the battery life as opposed to fully charging and and draining it to 20.
