Calibrating A Smartphone’s Battery

Melody in Nashville, Tennessee listens on WTN 99.7 asked us about her phone's battery

Melody asked: “How do I stop my cell phone battery from draining. I have the iPhone 6s Plus. The power bars goes down, it’ll say like 13 percent then my phone will die. Is there any way to keep that from happening. Do I have to let it die all the way, or do I need to stop charging it? How do I fix it?”

 

Melody, you can try to recalibrate your battery, but it’s probably just getting old.

To recalibrate your battery you have to put it through a couple of full charge cycles. That means draining your battery until the phone dies, plugging it in and keeping it charging until it reaches 100%, then do it again another time or two.

After a few charges, turn the phone off and back on and theoretically the battery should be better calibrated.

The expected maximum battery life on a modern phone usually around 500 cycles

Having said that, batteries are not pure electronics, they’re chemical devices and they wear out. The expected maximum battery life on a modern phone usually around 500 cycles, which doesn’t mean that you plugged the phone in 500 times, but that the battery was charged the equivalent of taking it from full to empty 500 times. Since the 6S has been out for a few years, you may be reaching the limit.

If that’s the case, the battery can be replaced, it’s just not meant to be user-replaceable, so you can get a new one, but it will take either some work on your part, or paying someone to get it done.
