Is it bad if I charge my phone when it is around 40%?
No, it is not bad to charge your phone when it is around 40%. In fact, many experts recommend keeping your phone’s battery level between 20% and 80% for optimal battery health.
Lithium-ion batteries, which are commonly used in smartphones, don’t have a memory effect, so you don’t need to fully discharge them before recharging.
Frequent shallow charging cycles, such as charging from 40% to 80%, can actually be better for the longevity of your battery compared to consistently draining it to near 0% and then fully charging it to 100%.
This is because lithium-ion batteries have a limited number of charge cycles, and shallow cycles put less strain on the battery overall.
Apple suggests that you aim to keep an iPhone battery between 30 and 80% charged, as do many others. Even if topping up to 100 percent isn’t ideal, it won’t necessarily harm your battery, but letting it constantly fall to 0 percent can cause a battery to die before it should.
It’s also worth noting that modern smartphones are designed to handle charging and battery management automatically. They have built-in circuitry to prevent overcharging and optimize charging speeds based on the battery’s condition.
So, as long as you use a reputable charger and cable, you can charge your phone whenever it’s convenient for you without worrying too much about the battery health.
