    Default Sudden battery drop at 10 percent - HTC One

    Every time my phone reaches around 10% it instantly drops to 3 or 4% then instantly after that to 1%... So basically I have to charge my phone before it gets to 10%. Not that big of a deal, but it is annoying not being able to do anything with it when it's at low battery and I'm away from a charger. Is anyone else having this problem? Any solutions?

    UPDATE: I'm trying to charge my phone before it gets that low from now on so I won't shorten my battery's lifespan so I can't comment on if the issue persist, but I will say that the calibration has helped the battery to act less weird as far as dropping fast in certain areas but not others. I'm just going to try not to think about it too much and charge it before it gets too low.

    battery calibration might help.


    don't make it a habit though!

    So, letting it drain to zero and recharging to full? I did that the other night with it powered off and still have the problem.

    this is more or less what i used to do when i had to calibrate my iphone:


    [HOW TO] - Calibrate Battery



    the main difference between his technique and mine was that i left the phone about an hour with a drained battery before charging it again.

    if your phone is rooted, there is an app that does all of this for you.

    some people on that thread say they've noticed increased battery life, but that is not what this does. what this tries to accomplish is to match your real battery capacity with the indicator, as well as minimising weird fluctuations.



    letting your battery drain frequently will damage it so beware.


    if this does not help, however, perhaps you should take it in for repairs.

    Okay, so this is like a once every few months kind of procedure?

    i wouldn't look at it that way.

    i've had my htc one for 6 months and have not done it once with this phone.

    my advice is you should do it only if your battery is behaving in a weird way.


    if its constantly wonky, it might be damaged or old already, and there is nothing you can do but change it.



    also, you seem to let your battery drain often. try to avoid that. in the worst case scenario, it is best to charge it when you get the alert at 15%. obviously, sometimes that might not be possible but at least try to minimise the use when it reaches that point.

    I do let it die more than I should, I usually make it through a day, but today I took it off the charger at 6:30 and it died at 5:00. I'm not sure what normal battery life is for this phone. I will do the calibration tomorrow and then start charging around 15% from now on. Thanks for the help and advice!

    Hey, quick question, I'm on the third step of the battery calibration and the 4th and 5th are confusing. He says to plug it in but let it sleep for about 30 mins, then the next step is unplug when light turns green. So should I let it sit plugged in for 30 mins or unplug it if it charges before then?

    unplug when its complete.

    don't worry if you extend the time though, it shouldn't really affect the process.

    My phone was at 21% and I unplugged it for a sec and plugged it back in and it went to 19%, and it was stuck there I then turned the phone off to see what it would say then and it said %15. Idk what's up with this thing.

    odd indeed.


    maybe check your battery history for that time to see if the graph shows these fluctuations.


    also, there might have been a process running in the background such as a back-up or something that could have sped up the battery drain.



    at the end of the day this is why i keep the % turned off in my phone. i can't be bothered to stress myself out with percentages lol. i just expect the battery to last for a certain amount of time and if i am not satisfied with it, i might look at the history graph to find out where all the juice went. otherwise, the only time in the day i know how much % of juice i've got is when i get the 15% alert.

    sometimes ignorance is bliss. but hey i ran out of ideas maybe try the battery guru : it might help to extend your battery life or avoid hick-ups by preventing certain processes running in the background more than they should.

    otherwise you'll need to change the battery.

    It did it a little after 5 pm, not that big of a fluctuation, although there is one spot beforehand with a sudden drop. I might have to turn off the percent cause like you said ignorance is bliss and I pay too much attention to it. As long as I can make it through a day on battery I'll let it be, but if it's get worse I'll get it repaired before warranty runs out in April.

    notice how the battery level is not going up even when charging after 5PM, especially when your screen is off? that is weird. the only time i get a drain even when charging is if im playing a very intense game. are you using your stock adapter?

    also, i've noticed your mobile network signal strength is very weak. this will consume more battery as well as the phone tries harder to connect to antenas. preferably, it should be dark green throughout (like the charging bar).

    Yes stock cable, and yeah signal sucks here. I also should mention that on more than one occasion I have woke up to find that it didn't charge overnight.. like it would be on 70 something %

    ya in that case you should definitely consider changing your battery. no amount of calibration will fix that.

    ya after an hour of being plugged in.

    also you have a curious drop between 1 and 2 PM.

    i bet those are the drops that are driving you mad.

    Yes, I can't stand it haha. I'm dreading sending this thing in again if it comes to that.. It'll be my 4th replacement, or I can get it repaired for the 2nd time. Htc didn't actually repair my phone last time though. An hour of plugged in but no charging is unacceptable. Kinda makes me want the old style removable back phones so I could just pop a new battery in. I'll just have to keep an eye on the charts

    to be fair, i think you havent been very kind to your battery


    whilst i am of those who think people should just "use the phone" instead of analysing every single angle looking for problems, the battery is the exception that to some extent, has to be taken care of if you expect it to behave.

    not too much heat, not letting it die, preferably charge above 20% and certainly no less than 5%.


    if you do some research, they'll all say about the same thing:



    once you get into the habit it becomes second nature.

    Yeah haha that's a fair assumption. It gets so hot down here in the south, it doesn't help. However I received this refurbished device from At&t in December so not too old, although it could have been abused before I even got it. Its hit or miss with refurbs, but it was my only option because It allowed me to keep my device, and the one time I tried Htc they didn't fix the issue.

    How does your battery do after you take it off the charger when full? My literally just dropped almost 10 percent in 6 minutes after it said it was full.
