iPhone Battery and Wireless charging: Any Side effects?
As we all probably know, iPhone 8, 8 plus and iPhone X are charged wirelessly, a feature some have considered has probable side effects in the long run, such as thwarting the battery’s lifespan or needing a replacement when it hasn’t reached its natural life cycle. But should you worry much about wireless charging and your pricey iPhone? Here’s more you should know.
Claims from some quarters say that power from the iPhone battery is responsible for the charging process, but this doesn’t add up really for some reasons and is also an erroneous claim, at best. Scientifically, we do know that a battery can’t simultaneously undergo a discharge and charge cycle, it’s an outright impossibility, at least for now.
Enough power is supplied when a phone is charged wirelessly or using a cable, to enable the battery charge and phone to run. So your phone basically uses the mains power, leaving the excess for the battery. If a low output charger is used, your battery might charge slowly, but it’s essentially the same process.
So if the power being released by the charger is 5watts, for example, the phone can take 2 watts and leave the excess 3watts for the battery. Some arguments claim excess charge cycles after a relatively short use. And this may be true since you’re ideally completing a cycle when you top up your phone using a wireless charger.
Apple states that its batteries can conveniently go through 500 charge cycles and still have a capacity as high as 80% of the initial. But this is not a one-size-fits-all rule and variations are possible. If, for example, you’ve completely undergone the 500 cycles, it’s not impossible to retain 90% of the phone’s initial battery capacity.
You may also go through 1000 cycles and retain up to 80% of the original battery capacity. Problems are however going to arise when you misuse or overheat your phone, in which case the capacity can rapidly undergo a negative spiral.
So we don’t necessarily have to worry about wireless charging damaging an iPhone. We should be more concerned about overheating and preventing them as much battery problems are linked to this caveat. Sure, wireless may come with some extra heat, but likely not enough to cause major iPhone battery issues or shorten the battery lifespan.
Investing a thousand dollars or more on a phone is definitely something to worry about. And nobody wants to lose such precious amount to wireless issues. The concern isn’t bad, for sure, but it also shouldn’t be all that disturbing, as wireless, much like its alternative, have identical charge cycles.
So if the concern still sounds worrying, you may want to only hit charge mode when there is a critical need to top up. This will ensure you reduce the pace of charge cycles and is an important step to elongating your battery capacity, whether you use a wireless or cable charged phone.
