    Accubattery states the estimated capacity is a little over 3400 mah when it should be 3800 mah! On my nexus 6p when I replaced the battery the fresh new one was over 110% health with an estimated capacity over 3800 mah when the designed capacity was 3450 mah. What gives? I have only had the phone for less than a month. I have no apps installed other than the stock apps and have all telemetry and various features disabled and it loses about 5-8% battery after about 4-6 hours of standby

    bruh, why are you checking the battery health? You phone is the same as everyone elses and no one is complaining about this, so its fine, dont trust that. The nexus 6p was known for its terrible battery and huge problems in battery longevity.

    normal I think. I have the 7t since it's release and the battery health is barely 90%. I have tested couple times and it doesn't seem to improve. just some days ago it was 84% battery life. it seems normal because it will never reach 100% , there is some degrading over time but on OnePlus phones it looks like the battery degrades faster. OnePlus needs to optimize batteries since their background is lacking on this topic. I had Huawei phone with 3400mah and after 1 year of intensive use it only degraded 8%. I recommend you not to test with charger that came with the phone, instead use a regular one and leave it charging without using The phone and you will see a battery improvement.

    what a disappointment. i went with this instead of a cheaper 6T or other phone for the sole purpose of ensuring a battery that meets the rated capacity (since it is brand new and not old stock). 'never settle' , yet it seems we have to settle for a false advertised battery capacity. The same crap happened with the stock nexus 6p battery. Fresh out of the box it was barely reaching 80% health yet as soon as I purchased a 3rd party battery the new capacity was far higher than the rating of the original OEM specs

    These are only estimations and should be taken with a grain of salt. It relies on the charging rate and since OnePlus uses a proprietary standard for charging it can introduce even more error to that reading.

    The thing is, though, the out of the box battery that accubattery said was at 80% health on the nexus, drained down from 100% to 89% in less than 15 minutes of use, and down to 50% after about an hour. With the third party battery and 110% health reading it would only drop about 5% after 15 minutes. So it absolutely does indicate the state of the battery, but the actual reading may not be accurate

    I have the same issue and was thinking to start a post before reading yours. I have my 7t pro for two weeks and right from the beginning, Accubattery app says 92% battery health, while I'm charging it up to 80% tops. I think is BS. Of course not all batteries have exactly 4.085 mah as the producer stats, since it can have some fluctuations, but a deviation of about 10%,that can't be right.

    I think it's quite obvious the problem is the accuracy of the app, not the battery from your phone.

    Regardless of numbers, it's clear that this oneplus battery holds up better compared to s10+ (previously owned) with around + 1.5-2 SOT (4100 mah on the Samsung VS 4085).
    Guess I made the right call to come back to OnePlus

    WTF
    How is it possible 110 % Battery Health 😆
    And the most funny part is that you believed it.
    Battery is 3800 mah don't worry about it.
    And why were you checking battery health when it's been just one month ?

    I am searching another procedure to check battery health on Google search! Ran into this thread on search! Heard 6t thread, accubattery doesn't accurately report battery! I'm down to 84% health on 6t, within a year! My new battery was measured at 95-97% health (what's 3% of 3700... About 150 ma difference! I've been using accubattery on last 3 OnePlus phones! It does seem like lithium battery producers do overestimate lithium battery capacity! 10% sounds like significant overestimate to fuss! But, I'm looking for method stating phone health to compare accubattery!

    True that. I own a OnePlus 7T and after six months of use my battery health is 85%.
    My iPhone from 2 years is still at 82%

    After almost 8 months. 95% battery health when charging it most of the times up to 80%.

    Use OnePlus diagnostics for better accuracy of your battery health.

    Yes I checked via the OnePlus diagnosis app only. And I too charge it upto 80 to 85% and most of the time never let it go below 30 to 40%
