So after a quick google search it appears my s21 ultra will not fast wireless charge using a non Samsung charger like the big that was reported with the s20. It'll start fast charging when first put on the pad and after 5 or so seconds it reverts back to normal wireless charging. Anyone else have this issue? I have uploaded a video and my logs using Samsung members but yet to have a response on that yet.
Solved! Go to Solution.
Hi, new S21 owner here. I just received my new Ventev Wireless Charge Pad Duo which charges up to 10W per device and even says compatible with Samsung's Fast Wireless Charging.
Well, when I place my phone on the pad, it says fast wireless charging then 5 seconds later it switches back to regular wireless charging and adds about 30 min more to full charge.
Ironically, my GF has a Note8 which gets the fast wireless charging when placed on the same pad.
My phone's on February's security patch.
there was an update that does not support fast wireless charging for uncertified 3rd party product. Note 8 might support fast wireless charge because this update was not applied on note 8.
check with ventev, or try submit report on samsung members to check if your product is certified by samsung.
Samsung wireless charger and same issue, at most 900ma rate screen on or off
Meanwhile past phones can fast charge screen on or off but samsung messes it up. You know the real limit is temperature, which is already accounted for!
Still a problem. Goes from 990ma to 500ma after a minute or so.
Happens screen on or off...
Also, why does samsung severely limit charge while screen is on? My last phone didn't, it limited charge by temperature which is much more logical!
