It seems like plenty of people believe that leaving their smartphones plugged in overnight will cause them some sort of serious harm, like the Big Bang or the Reign of Fire. But the reality is that your phone will just get charged, thanks to the protection chip built in. This myth has been around for a while now, and it seems to be dying out as smartphones have evolved into more advanced devices.
Our smartphones are so integral to our daily lives that their batteries couldn’t ever keep up with our daytime needs. Which leads to charging your phone overnight. Because it’s a better time to recharge than when you’re sleeping, but then the paranoia and fear come hailing down on you: overcharging your phone and battery explosion. Leaving you with a dilemma you’re all too familiar with.
Convenience or safety???
A tiny note: an auto cutoff cable can help take the burden of prolonging battery life off your hands.
During overnight charging, your phone constantly uses battery to stay functional, much like all things living; and when consumption happens, recharging happens. And this opens up to a hell of short-lived battery for whoever couldn’t bear to replace their phones every year or two. (If you do, however … Well, you may skip this reading. Most phones nowadays use lithium-ion batteries (LiB). They are rechargeable and recharge very quickly, reaching 80% in a flash. This is thanks to all the fast charging technology boasted by many a smartphone titan (e.g., Huawei and Samsung). However, because of that, phones now take 1 to 2 hours to fully charge. That’s really saying that your precious phone spends most of its time hooked to the charger at 100% battery while you’re fast asleep. But … what’s the deal?
Stress on Lithium-ion battery. There’s no arguing that Li-ion is superior among batteries. But a champion is not without its weakness. In fact, it’s bordering counterintuitive: Li-ion suffers from stress when dwelling at full state-of-charge (100%). And when it does so consistently month after month, its recoverable capacity will drop; though the decline may not amount to much in the short run, it does leave a dent in the battery capacity that will be a long-term thorn in your side.
When charging, Lithium ions swim across the cathode (the positive electrode of a battery) to anode (the negative electrode), which is exactly how it should be. But it is during which that an irreversible damage also takes place: electrically-insulating rock-salts form & buildup over the cathode. Overtime, the buildup grows and battery capacity shrinks. The worst of all, the buildup blooms like wildflowers after rainy days at higher battery levels and temperatures. Certainly, maintaining a high battery level longer will degrade the battery faster. And this is even more harmful than cycling a battery.
conclusion
- smartphones are smart, no need of worrying about it; when the charge reaches at 80% the charging speed decreases
- at 100% of battery level phone charging will cut off automatically
- latest phones have built-in charging regulator
our advice
however do not charge your phone at night because we should keep the battery level between 30-85% . this is better for our li-ion batteries. experts says the battery level should maintain 30-85%. do not overcharge your phone for prolonged usage. and keep your battery temperature below 45degree. fast charging makes your battery temperature high. if you don’t care about batteries you can charge your phones at 100% because there will be about 400 charging cycles are there. normally it will goes upto 2-3 years.
if your are a prolonged user, and worrying about battery life, and wanted to use your phones more than 4 years, you should take care of your phone. you should follow our points as we mentioned above.
