    Hello everyone,

    I was wondering if anyone that has the AccuBattery App installed could please let me know what is your battery health?

    Before the V20 I used to have the s7 edge and the even after 6 months of use with very heavy usage (about 150-200% a day) the battery health was at 95% according to AccuBattery, it was about 3400 out of 3600 mAh.

    Now with the v20 since the beggining it said around 90% and after about two weeks of use it's still at 91% or about 2912 out of 3200 mah.

    Then I bought a a spare battery and charging craddle kit (BCK-5200) and uninstalled AccuBattery and installed it again and after using the new battery about 5 days it's even a little worse at 88% or 2833 mAh.

    If you guys have the app installed could you please let me know what it says on battery health?

    Thank you!

    First, I would never use an app that has a blurb on Play that says "we don't understand how lithium batteries work" - and AccuBattery does.

    Second, discharging a 3600mAh battery by 3400 mAh means that you're almost totally discharging the battery - one of the fastest ways of permanently damaging it.

    Stop killing your batteries, get a new one, and start charging it when it drops to between 50% and 40% (but try to not let it get too close to 40%). If you want to see some real figures from some people who really know batteries, see Battery University - How to Prolong Lithium-based Batteries. That's by Cadex, people who have been in the business since before anyone thought of cellphones. They've been using, abusing and destroying lithium batteries since the chemistry came out, so they should know a few things about them.

    Thanks for the help! What I meant with the 3400 mAh is the app constantly measure the mAh the battery is charged each time and the mAh the battery is discharged each time. Then with the average it gives you an "estimated capacity" and compares that to the "design capacity". For the s7 edge my estimated capacity was 3400 mAh (when the gage says 100%) of the advertised 3600 mAh but that was after 6 months of discharching to 0% almost daily and charging several times during the day, plus charging it to 100% overnight almost daily too. I know my habits would degrade the battery life faster, especially discharging to 0% as you mention, but having 95% percent of actual capacity of the total advertised capacity made me not worry too much about it since I don't even last more than a year with the same phone. In case of the AccuBattery app was BS I never noticed and difference of my average battery life or SOT from day one or the day after 6 months either.

    However, I wanted to see if someone else has the app installed on the V20 what is the "estimated capacity" they are seeing. I don't think the 88% that I am seeing is going to change and 2833 mAh of actual capacity compared t the 3200 mAh of advertised capacity is not good for a 10 days old battery.

    My phone works for me. I don't work for it. If I can swap my battery or recharge it before it is fully depleted I may choose to, but I'm not going to be going out of my way to try and preserve its health. I'll just replace the batteries and keep it moving.

    That being said, from what it sounds like, this app may be garbage. The last battery app I ever used was on webOS and was called batteryDR. That was a great app. What I do wish was available and functional is an app that actually shows what mAh draw the phone is currently charging (or discharging) at.

    I have downloaded this app. It shows too much information and nothing is proven to be accurate here. It all comes down to what you trust in a certain app. I removed it after 2 days as I did not trust the information that I was receiving....... Just my IMHO

    I am the same, I am not going to frustrate or bother everyday trying to swap/charge early or trying to not charge to 100% just so the battery would last 10 minutes more after 6 months than it would if I didn't had them at 40-80% all the time, especially with removable batteries, if I do notice a degradation I'll just buy more batteries, the genuine ones will be less than $15 in a few months.

    However, I hope the V20 batteries are not coming with a capacity of 2800-2900 mAh of the advertised 3200 mAh.

    Is there an app that you trust? GSam/Better Battery Stats doesn't work with Nougat and the other traditional battery apps like Battery Doctor Pro or similar does not do absolutely anything to help you prolong the battery life as they promise just kill system apps all the time which it can be even worse for the battery.

    I don't dislike accubattery because it doesn't tell you is going to magically extend the battery life after you install the app. It just gives you information and stats. I also use it sometimes to see how much percentage it charged in a period of time to test what chargers are truly quick charge 3.0 compatible.

    I wouldn't worry too much about battery life. I also wouldn't invalidate the stats from the app as well....but this type of probing is not warranted given that the batteries are easily replaceable at very low price point. If you start seeing noticeable degradation or can't seem to hold a charge then maybe you can take a peek, but at this point you're just feeding into the paranoia.

    Just for fun...there's also a couple of theories that say fast charging lithium-ion batteries hurts the longevity. They would rather have charging or discharging happen at slow steady pace. You also need keep the charge above 50% at all times, but a one time monthly "calibration" going from 100% to 0% also helps. I could keep on going, but you get the point.

    The quick charge test can also be done using standard battery meter showing percentages. The power graph for the battery usage should also help.

    Hi. I'm using a v20 and bought it just last November. I didn't have a prob with the battery not until I noticed it gets hot when I'm playing the game that I used to play without battery getting hot. So I got worried and found this Accubattery app. I had this only for 3 days if not 2. Battery health was on 92 percent and now down to 89 percent having 2856 mah out of the 3200mah. That was based on 5 sessions with 202 percent charged for 5769 mah total.
    Since i had this app i charge my from 50 percent to 80percent as what they recommend.

    However i still have doubts in this cos earlier today i had this battery health at 91 percent and tonight had it at 89 without me draining the batt and fully charging it.

    So I'm confused too

    Had it installed for a while , checked the health and it's 89% so nothing to worry about I think.

    I've had my V20 for almost 2 1/2 months, use it during the day and charge to 100% every night.

    Accubattery shows 99% health (3159 out of 3200).

    Also I have to say since the US cellular Android upgrade a week ago, the standby battery life is MUCH improved. It still isn't quite as good as the Note 7 for screen on time but I've gone 5 or 6 hours at work with not much use and still been at 99%. It would have been around 91% before the upgrade.

    My battery is apparently at 68%.

    Should I replace it? How much would a replacement battery be for the nexus 6p?

    I was thinking of upgrading to the pixel 2 in the autumn but maybe my phone isn't going to last that long without the battery replacement.
