Is wireless charging bad for battery?
Although wireless charging technology has been around for nearly 200 years, many are still concerned about whether it will cause damage to their phones’ batteries. Wireless charging charges your phone the same way as wired chargers.
A coil is used to create a magnetic field. The receiver coil inside your phone will then generate current by converting the magnetic energy into electric energy. You don’t have to worry about your phone being plugged in multiple times per day via wired cable. Wireless charger is not necessary.
Wireless charging technology is becoming more common in everyday life as more smartphone manufacturers include it in their flagship models. This will increase the quality of our lives and improve our quality of life.
Wireless charging are more convenient in most cases. Wireless charger allows you to eliminate cables from your desk and charge your phone with no additional attachments.

Is it a bad idea to have my phone fully charging all the time?
Wireless charging has a few disadvantages. Your phone might not be fully charged at all times. Charging wirelessly is very beneficial for daily life. But, will it harm my smartphone’s battery?
Many people believe wirelessly charging will reduce the smartphone battery lifetime. Is this true?
The battery can decline if you charge your phone constantly. Matt Reynolds – the Expert said:
“Charging your phone so it stays at 100 percent overnight isn’t great news for the battery, but that’s not because you’re cramming in more charge than it can handle.
A ‘trickle charge’ mechanism cuts off the charger after the phone has reached 100 percent charge and only tops up the battery when it drops down a little.
The problem is that you’re keeping the charge level at 100 percent, which, as we know from the previous myth, puts the battery under a certain amount of strain.”
Kent Griffith, a University of Cambridge expert, said that phone battery manufacturers had added battery management system (BMS) technology to prevent damage from constantly charging. The BMS system prevents your phone from being overcharged, which can cause battery death within a few months. The smartphone system built-in app even stops our phone from being overcharged.
Although it may not be “good” to keep your smartphone charged all the time, it won’t cause any harm.
According to industry research, the actual increase in battery life is fourfold when the depth of the discharge (or the amount that the battery drain) is less than 50%.
Menno Treffers is the chairman of the Wireless Power Consortium. “In other words: By constantly topping off your battery throughout the day, like you might with wireless charging and not letting your phone battery dip drop below 50%, you will increase the battery’s lifespan.”
The convenience of wireless charging and the battery life are the two main benefits I choose. Batteries should always be replaced, regardless of how you charge them.
It is easy to replace a battery on your phone or have it done by someone else for about 20$ (for iPhone, a bit more). An AppleCare extended warranty is available for $20. You can choose.
The wireless charger will not harm your phone’s battery life
To be more precise, heat generated by wireless charging won’t cause any damage to your battery.
Wireless chargers offer a stable current
Wireless charging, also known as inductive charging, is a better option than using a wire to charge your phone. Resonant inductive pairing is what makes wireless charging possible.
This involves a transmitter coil in the wireless charging pad and a receiver coil in your phone to make the “electronic” connection. These two coils convert the electric current into a charge that is then stored in your battery.
Place your phone on a wireless charging pad to charge it.
But how does the current flow within?
The wall adapter, a wired charger, takes AC (alternating current), electricity from the mains supply and converts it to DC (direct current) to charge your battery. The voltage is often higher.
Although the current is usually higher, it is unsafe and unregulated. It operates at approximately 1.6 Coulomb transmitted current per sec (the equivalent of 1.6Amps).
Wireless charging uses a current of around 1 Coulomb per second, which is equal to 1Amp. This is very different from wired charging. Wireless charging uses different transmitters and receiver coils.
It has a lower current than wired charging and the separated coils (for example, the Qi charger). This makes it a safer and more stable charging environment for your phone’s battery. Wireless chargers can be beneficial for your phone over the long term.
Battery cell is not affected by heat
It is possible to wonder if heat can cause damage to the battery, as it can get very hot.
The semiconductor (such as the back cover of your phone) generates heat through the current flow and not the actual lithium-ion battery.
Because lithium batteries are not semiconductors, they don’t have electricity passing through them, so no heat is generated.
But, what about the heat from other semiconductor parts? Will it affect the battery if they become too hot?
Your phone battery is intelligent enough to protect itself.
Our smartphones heat up easily when they are charged, which can cause damage to the battery. The phone can manage the charging process and stop it if it gets too hot.
How is this possible? The protection board that protects rechargeable lithium-ion batteries in smartphones is called a PCM (Protection Circuit Modules).
It prevents the battery from operating beyond its safe operating limit. It monitors battery status and other data and reports this information to the motherboard for temperature control.
This is an excellent example of the iPhone. Apple claims it can charge up to 50% with fast charging (7.5W), true if you have a suitable charging cable. What you may not know is that charging speed slow down.
Mashable’s test showed that the iPhone X could be charged to 46% within 30 minutes. However, it takes 2 hours and 5 to charge the remaining 52%. The charger you use will determine how fast your iPhone X charges.
The charger must dissipate heat efficiently so that the phone can be charged at a higher 7.5W (watts). If not, the charger will drop to 5W to prevent any damage to the phone batteries.
What can you do to protect your smartphone battery from rapid aging?
Although wireless chargers can be good for your smartphone’s battery, it is important to remember that they have a finite lifespan and will eventually start to degrade.
If you charge your battery incorrectly, this can accelerate the process of battery degradation. There are many ways you can prolong the life of your smartphone battery and keep it in top condition.
Deep discharge your phone battery
Yes, the smartphone batteries operating system can calibrate your phone’s entire life charge cycles by discharging it to zero at least once per month. This allows it to know how much battery capacity it has. The battery’s lifespan is limited, so you only get one cycle per month.
Battery University discovered that there is no memory in a battery and that it does not require periodic complete discharge cycles to extend its life. The regular deep discharge will not prolong the battery’s life, but it will slightly reduce its lifespan.
Keep your lithium-based batteries at 50 to 80 percent. This will help prevent battery drain. Battery capacity progressive charge cycles can cause decay.
What can you do to avoid unnecessary damage?
It’s easy to keep a lithium-ion battery in good condition if you plan to store it for a while. If you want to keep your battery in its best condition, reduce the time between deep discharge and calibration.
Battery life will be longer if it is discharged at a lower level (low DoD). Avoid total discharges if possible and charge your battery more frequently between uses.
Fast charge your phone often
It might be a concern if your phone is charged overnight using wireless charging. Smartphones are smart enough to know when it is safe to charge your phone overnight with wireless charging.
According to the US Department of Energy research, higher voltage batteries can cause more ion path irregularities and faster deterioration.
Consider charging the battery frequently. It will lead to the lithium-ion battery faster than normal, regardless of how fast you charge it.
When charged and discharged at low speeds, lithium-ion batteries last the longest. High-voltage chargers can cause rechargeable batteries to lose their ability to hold a charge.
However, the damage shouldn’t be too severe as fast charging is just at the beginning of a recharge cycle and phones and chargers are intelligent enough to limit the amount of voltage that they apply when needed.
However, it is better for your battery to charge slowly and steadily with a low-voltage charger if you aren’t in a rush.
The battery has overheated
The safe operating area of a lithium-ion battery determines the maximum temperature your battery can withstand.
Extreme heat is their greatest enemy. Your phone’s ability to withstand temperatures exceeding 40 degrees Celsius could cause significant damage or even death.
Don’t confuse overheating with the heat that wireless charging can cause. This is the heat that is mainly caused by the weather. It is enough to be aware of the temperature.
Your device’s battery will be affected by temperature changes, particularly extreme heat. Extreme weather can cause your phone to lose its charge if exposed to direct sunlight or temperatures below 0 degrees.
Are there any downsides to wireless charging? Yes, but your battery will eventually lose its ability to charge, and it has a half-life. In addition, wireless charging offers convenience and speedy charging. You can also keep your battery charged by using the right charger, which should offer wireless charging at its best.
