    I've charged my OP3 connecting a DROK USB Digital Multimeter to the charger and the capacity showed by the app was about +-5 mAh showed by the multimeter. I too have a 2748 mAh battery.

    It's a well known fact I pimped the hell out of accubattery on here. I talked about it so much, people accused me of working for accubattery lol. I've used it on 4 phones. All 4 were brand new, and I downloaded acubattery on day 1.

    s7 - 99% initially. Down to 95% after a week. Down to 93% after several months
    s7 - 98% initially. Down to 93% after a week
    s7e -99% initially. Down to 94% after a week. Down to 93% after a month
    OP3 - 93% or so initially. Down to 89% after 3 months

    Accubattery is an awesome app to log your battery data, especially because it calculates how long the screen was off, and how much of that time was spent in deep sleep. I emailed the developer, and they said the same thing as to the guy on page 1. I verified this 100% without fail. The OnePlus3 will say 100% and the green light will pop up as soon as it hits 100%. It is still trickle charging, though. I sold the phone so I can't be exact, but I believe it takes another 10-15 minutes @ "100%" for it to stop taking in any charge at all. In dash charge it is taking in over 1000ma. When it's trickle charging at 100, it's taking in maybe 200ma. The same thing happens on my Wife's s7 and my s7e. It just must be how it goes with android phones.

    There are folks on the s7e subreddit who have had their phones since March. The accubattery stats for them are around 81-83%. I have no doubt it can calculate capacity roughly, but the fact several of my phones lost 5% after 1 week of use shows me the calculations are flawed. It seems weird that a OnePlus 1 and a OnePlus 3 will both show roughly the same capacity. This is very hard to believe, due to calendar aging and other factors such as the OP1 most likely having gone thru many more charging cycles.

    tldr accubattery is awesome, but take the capacity estimate with a grain of salt

    In seven months my phone battery is only working at 86 percent capacity is it normal. I have always charged phone to 100 percent and only once daily. Are these stats accurate?

    Did you buy this directly from One Plus or from some third party reseller? That might make a difference.

    I have the same "problem" and I think that it is with the software rather than battery since accubattery read out the charges from 0-89% and 90-100% a two separate charges there for not including the second one into calculation since it is smaller than 20% those are the grey dots, I think that it's probably because of difference in amperage.

    To those of you saying X says 3000mAh, that is because the max design capacity is coded into the battery circuitry to tell OSs what it is. It doesn't mean it is anywhere near that. It is merely an identifier.

    I've moaned at OnePlus since September last year about receiving a phone with only 2700mAh on my OnePlus and my experience with the phone has always indicated that battery life is shorter than it should be. OnePlus has always denied it.

    I will never buy a OnePlus phone again because the batteries vary between each device so much and OnePlus just deny it. Now after all this time, my battery has 2600mAh, which is to be expected, but had my phone shipped with a good battery, I'd be at about 2700/2800 now and my phone would still be more usable. I have to turn everything off, pick black themes, ensure no apps are running or causing wakelock issues. My phone is a dumbphone not a smart one and this is all because of cheap batteries. This is where OnePlus saved money. Inconsistent all over. Not at all pleased.

    I personally use Battery Charging Android App, with the help of this we can easily know all the hidden details of battery you can even know battery capacity as well as battery health.

    My OnePlus 3 has 83% capacity after 1.5 years of heavy use. I'm not sure, but I think it had 87% after 6 months.

    Sounds like it, but why ask in an OP3(T) thread that's been dead 2 years?

    is there an actual reliable way to check battery health to see if the battery is the reason that my phone will now lose it's full battery in a couple hours?
