We all love our smartphones but hate the battery timings. Gone are the days when a phone lasted for many days on a single charge. Today, consider yourself lucky if your phone’s battery lasts a day on a complete charge. It is partially due to the power hungry apps and screens of the smartphones and partially because of our bad charging habits. We have adopted some myths as facts that are actually more damaging to our batteries than anything else. A site from battery company Cadex called Battery University details how the lithium-ion batteries in our smartphones are sensitive to their own versions of “stress.” And, like for humans, extended stress could be damaging your smartphone battery’s long-term lifespan. Here are a few things that you should keep in mind while charging your smartphone.
Don’t Keep It Plugged In When It’s Fully Charged
According to Battery University, leaving your phone plugged in when it’s fully charged, like you might overnight, is bad for the battery in the long run. When the phone is 100% charged, it gets small or “trickle” charges to keep the battery charged up to 100%. This increases the stress on the battery and keeps it in a high-tension state which ultimately hurts it very badly. Battery University explained it in very simple words. They say that removing the battery from charge after it is 100% is like “relaxing the muscles after a strenuous exercise.” Everyone who goes to the gym would know how much that helps in increasing and relaxing your muscles. Same goes for the muscles i.e. cells, of our batteries.
Try not to charge it to 100%
As absurd as it sounds, this is actually a very useful tip. Do not charge your phone to full 100% unless you have to. According to Battery University, “Li-ion does not need to be fully charged, nor is it desirable to do so. In fact, it is better not to fully charge, because a high voltage stresses the battery”. This might be a little bit more of a hassle but you should plug-in your phone whenever you get the chance during the day.
Plug in your phone whenever you can
It is a widely believed myth that your battery cells wear out eventually if you keep charging them more often. Therefore, many people prefer to go for a long single charge during the day, mostly when they go to sleep. This is more damaging to the battery than the other way, which involves charging your battery in small bursts whenever you get the chance during the day. According to Battery University, the optimum time to charge the battery is when it loses 10% of its charge. It is perfectly fine to plug and unplug your phone multiple times during the day. Not only does this keep your smartphone’s battery performing optimally for longer, but it also keeps it topped up throughout the day. This way you might be able to use some features like location detection that you normally turn off to save your battery.
Keep the Battery Cool
Smartphone batteries are so sensitive to heat that Apple itself suggests you remove certain cases that insulate heat from your iPhone when you charge it. Battery University says that if you notice your device getting hot when you charge it, you should remove the protective casing, if any. You should also charge your device in relatively cooler places and avoid charging in direct sunlight or near a fire or a heater.
