    Leaving your phone plugged in overnight is the cause of a miscalculated battery. You shouldn't let your batter stay plugged for more than 30 mins after it is fully charged.

    I have only had this issue a few times. Since I've stopped letting it over-charge, never had the issue again.

    P.S. Allow your battery to shut off completely at least once in every 14 days. This also helps maintain the life of the battery

    Updating the OS can sometimes require a recalibration of the battery. Just allow the battery to fully discharge and then fully recharge to recalibrate it - you might need to do it a few times.

    Some other tips for extending your BlackBerry 10 battery life.

    Umm..I wouldn't really blame overnight charging cause of 'miscalibration' because since the beginning I've always plugged my z10 at 1-2am and plug it out at 11am. It does overcharges and the calibration problem was still there but it went away right after I installed the 10.0.3.1154 leak. And I overcharge it everyday. No issues for me except it just shuts down at 10-11%. Not a big issue after all charging over night saves a lot of time. So I think overnight charging is pretty much safe for the lithium batteries which our z10 uses.

    I have had the same discussion here in CB and some people who seems to know much about it said me, all these are old stories...modern battery comes with some intelligent sense and it stops right after being fully charged...so over charging is a never problem it seems...and about all the battery miscalculations we face in BlackBerry, I think is due to result of OS. Coz when I did my 10.3.w leak, problems I faced with battery was almost gone. But when I reload it to 10.2.1, I got them back...

    I plug my phone in every night and leave it and I have never had a problem with the battery calibration.

    Would that harm my battery or z10 if it remains in charging for whole night? I mean it would get fully charged in 90 mins, would it effect battery or z10 if it remained plugged for 8 hours?

    I also have the same issue of turning off the device on 40 to 60 percent sometimes, so if getting 10.3 leak is is the solution, please. Suggest

    Miscalibration is a problem of STL 100-1. Other models don't have this issue. So, I guess it's a hardware problem. If the upcoming 10.3 will not solve the problem, I will give this phone back. a 750 usd phone should not have such problems...

    Leaving it until it shuts downs seems contradictory to some posts i've read. But thank you I'll reconsider this method
