    Hey,

    I've recently replaced my aging S7 Edge battery after downloading an app (AccuBattery) that reported that the calculated 'health' of the battery was below 60% and it only had ~2000mAh of useful charge, compared to the as-new 3600mAh capacity.

    However, after a rather painful DIY experience to replace the battery using the kit from iFixIt - the reported health of the battery has not returned to decent health. It has gone up, but only to around 72% health after 15 charge cycles of measuring.

    I'm not looking for 100% health, but I would expect a new replacement battery to be able to do 90%+ of the reported capacity.

    I have tried draining the phone until it turns itself off twice, but no real effect. Can anyone help? I would strongly prefer to avoid rooting the phone.

    Thanks :-)

    Welcome to Android Central! Where did you get the battery from? If that battery has been sitting around on a shelf for 3 years, it's possible that it's deteriorated significantly.

    Also, calibrating the battery is basically charging until the battery voltage stops going up, then setting the calibration file to that voltage = 100%. But the file has permissions only for the system, so the phone has to be rooted to do that.
