    Hi guys, just wondering can anyone explain what is going on with OnePlus's 65warp charging against accubattery estimation? This is my first time charge with accubattery and it show as pic. Should I be concerned about this phone's battery or there's some mistakes in app's calculation? Or is there anyone having the same issue on 8T?

    Clear storage of Accubattery and retest your battery health by charging again.

    See if the results are different, cuz Accubattery needs several charge cycles to accurately measure your battery capacity. Though 50 percent does sound weird.

    I ended up going through the same cycle of confusion. I installed lots of different battery capacity detector apps and I got about 2225 mAh battery capacity reading. I called "OnePlus support" and I asked them about the battery capacity on OnePlus 8T, and if it's an issue, they told me that I can return the phone!!!! Zero attempt from OnePlus to provide some sort of clarity to the customer. It's like buy the product and then you are on your own. I don't how they are considered a flagship killer. A good brand would always tries to provide some support to the customer instead of telling them you can return the device. I realized if I have talked to a bag of potatoes, most likely I would get some sort sort of answer regarding the battery capacity on my device. Last night I got like 8 hours of screen time and I had about 20% charge left. That's when I realized most likely the apps can't detect the second battery. When I saw this thread earlier today I realized that I am not the only one who has the question about the battery capacity with 8T. Thanks to those who provided some clarity here, shame on OnePlus for failing to support their products. This 8T was going to be my 3rd device, but now I am going to return my 8T and get a samsung s20, most likely would be a boring phone but at least I can get my questions answered by samsung and when I call samsung support they don't offer me a return label. Also I need to add that itlf you want to return something to OnePlus they will make you to return thier so called mystery gift as well, and it takes 48 hours to get a return label. Very disappointed!

    Are we gonna ignore the blatant "Based on 1 session with 82% charged for 1,800 mAh total" at the bottom? It's like saying you got one problem wrong on a test and instantly get an F (or the equivalent of "failing" in other countries). o_O

    Take look at the estimated capacity! It's obvious.

    Yeah, I saw that. That's why I said, the app needs several charge cycles to accurately measure the capacity.

    I would imagine the app is not set up to read the dual battery config on the 8T properly.

    The battery life served me very well so far, a full charge normally taken around 35 mins will last me two days or at least 40% by the end of the day. Compare to my old pixel 3xl which only last about 2/3 of the day with 1.5-2 hours charging, I'm really pleased! I would believe there's problem with the app that couldn't process well under 8T's dual battery system.

    Same here, after several cycles, the battery life is reported at 47% and estimated at 2112 mAh.

    that is going to be the app not being coded to correctly recognise the battery config.

    I noticed the same thing on my phone I've charged it at least 20 times from low battery to what Android considers full charge (between 85 and 100%) and Accu battery still says 2155mAh.
    I don't know what is causing this but I don't like it.

    8T has two battery cells.

    The 8T has a split battery (it is how the fast charging works) the accubattery app clearly is only reading one of the cells and doesn't know to look for a 2nd one.

    the issue is with the app, not the battery. The app does not know about split battery tech (the 8T battery is split in two halves which can charge simultaneously to give faster charging). It is only reporting on the 1st half of the battery, not both halves. There is nothing wrong with your phone.
