    Hi guys.
    I've charged the phone via some Samsung wireless charger (5V,2A) for like 3 hours (only 50%).
    I just wanted to test for first time wireless charging time.
    I can not find OEM Samsung wireless charger here for my phone.
    When I took off the phone from pad the back of the phone was very hot (not extremly hot).
    Pad was hot too.
    Is that normal?
    Do I need some other wireless pad for this phone?

    I know when the battery is hot that is not a good sign.
    I did some software tests if those are to be trusted and they doesn't report good result except Accubattery.
    So how will I know if the battery is for replacement?
    Phone was purchased back in fall 2019,from first user and me as a second user got it in april this year.
    I wrote before that my Screen on time is around 6.5-7 h watching yt vids 1080p and light browsing,with medium brightness but with power saving mode ON.
    How will I know when is the exact moment to replace my battery?
    I guess I will need to use phone without it's protection (Poetic case).With the case on the phone I don't see if the bat is swelling or not, because this case is quite wide.
    But through it I don't see anything unusual,back cover looks normal.

    3 hours is a long time. But rather than the battery failing it is likely the wireless pad only charges at 5W or 10W and that is what takes time. A lot of chargers charge that slowly wirelessly. Samsung does a 15W wireless charger but wired is almost always faster.

    Correct me if I am wrong but Li baterries preffer slower charging with less current.
    It's better for the health of the battery-

    My understanding if manufacturer design the phone and battery for Fast charging and they do all the testing its fair to say its ok for the health of the battery.

    I agree usually around 2 year mark possible 3 the battery going need replacement depending on how user uses the phone, do i trust apps that measure battery health , I'll put it this way i dont think they are as accurate as a true tool but they can give a round about where its at , think of your car the warning lights like fuel gauge , it gives us a round about but its not precise.

    I've got 2 of Samsungs original wireless chargers from back when the S6 launched, they take like 5-7 hours to charge my Note 20 Ultra. Lol

    When my Pixel 3 XL hit the 2 year mark, the battery health as reported by AccuBattery was 90%. I was habitually charging that phone to 100% (letting it charge overnight), so that gives you an idea of the general wear on a battery with those charging habits. Since my Pixel 6 Pro has a much larger battery with great battery life, I'm changing my habit so that I'm mostly charging up to 80% instead, which is supposed to prolong the battery lifespan.

    The general rule of thumb is that if the battery health hits 85%, it's pretty much done (in terms of real world usage).
