1. Charging Overnight Destroys Battery Life
This was a fact which held true for the earlier smartphones — they would overheat if left plugged in for too long.
Thankfully, the modern smartphone and its components — battery and charger — can effectively control the power management. In fact, when a phone is fully charged, the internal circuit will be cut off and will only begin charging again once the battery level drops below 100%.
And if you are wondering if the aforementioned method — trickle charging — of charging is dangerous to your smartphone’s battery life, then be assured that it isn’t.
Trickle charging is actually less harmful than the normal discharging process. On the same note, people advising against talking while a phone is charging are also referring to a myth.
And that brings us to the second myth…
2. I can Leave the Charger on Forever
Well, practically yes, you can. If you don’t love your cell phone at all or you change your devices too often. But if you care for a longer life of your battery, then the best way to charge is not going over 80 or below 10.
Every battery comes with a fixed amount of cycles and these cycles tend to wear off the more you charge your phone.
In fact, charging your battery to 80% on a regular basis is shown to increase its life by 200%. So do make sure that you maintain the sweet spot of the battery — 10% and 80%, with an occasional 0% discharge to calibrate the battery life.
3. Closing Apps will Save Battery
If you are one who swears by the mantra that closing apps will improve battery (and performance), then you are in for some news.
The fact is closing apps does more harm than good. Chances are that you might actually end up draining more battery juice in the process.
Closing an app suddenly might result in losing data. Also if the phone needs to restart the app again, that will require more CPU resources and hence, more battery.
4. Letting the Battery Drain to 0% Every Day
This again is a tale from the ancient days of Nickel Cadmium batteries of the 80-90s. Nickel cadmium batteries had the memory effect, which essentially gave rise to this myth.
After these batteries were recharged for a couple of times, they would forget their full capacity and eventually weren’t able to hold the charge. The discharging was done to reset the ‘memory’.
The Lithium-ion batteries used nowadays have a smarter way of power management. It counts a cycle when you have used 100% of the battery in multiple uses.
For instance, if you used 40% today, and 20% on two consecutive days then only it would call for one cycle.
5. 4G Drains the Battery Faster
It’s true that radio signal consumes lesser resource than cellular data. However, that should never be the cause of your battery life going for a dive. If you have a good quality SIM from a reliable operator, then it shouldn’t be the cause of a meltdown.
6. A 5000 mAh Power Bank will Yield 2 Full Charges
Often it’s assumed that a 5000 mAh power bank will be able to yield 2 full charges for your 2500 mAh battery. How did we arrive at the conclusion? Simple, just dividing the capacity by the full power.
But that’s not how simple as it seems. The catch is the voltage at which it charges. The power rating of a power bank is calculated at 3.7 volts whereas the phone charges at 5 volts.
Only when a step down in the voltage is made, that the right number of charge cycles can be determined. So, the next time you are on a lookout for a power bank, do make sure to do the math.
7. Charging Through a Laptop may Damage the Battery
Again a misconception, charging a phone through a laptop will only yield a slower charge and nothing more. This won’t harm the battery in any way.
The same holds true for your car’s charging port as well.
8.More Megapixels Mean a Better Camera
Megapixels aren’t just a myth for smartphone cameras — they’re a myth for practically any type of digital camera. The myth is that a larger number of megapixels is always better. More megapixels look good on a specification sheet, and manufacturers can trumpet the number of megapixels their smartphone’s camera sensor offers.A megapixel just means one million pixels, and the number of megapixels tells you how many pixels a photo you’ll get from the camera will contain. Apple’s iPhone 6 still has an 8-megapixel camera, while high-end Android smartphones often offer 16-megapixel cameras.
In a nutshell, cramming more and more ever-smaller pixels onto a sensor isn’t always a good idea. Compared to a 16-megapixel camera, an 8-megapixel camera sensor of the same size will have larger pixels, which can let more light. More importantly, the overall quality of the sensor, lens, and image-processing software is also very important.Never just compare the number of megapixels if you’re comparing smartphone cameras — look for actual comparison reviews where the reviewer actually took photos with each different phone and compared them. Don’t get bogged down in meaningless specifications.
9. Overcharging my phone will lead to explosions
While the Note 7 remains the only phone in recent memory (en masse, at least) to catch fire in a number of different scenarios, overcharging seems to have spread fear in people everywhere. Even though older Lithium-Ion batteries did overheat, we’ve seen tremendous progress made in this area over the years.
Now, chargers and batteries are optimised to not only stop charging when it’s 100% charged but also keep the heating in check. Researchers have also been working on a new kind of battery tech that will shut down the battery when high temperatures are detect and restart when it gets cooler.
10. Will disabling Bluetooth, Wi-Fi and other toggles save battery?
Similar to disabling background data refresh for apps, toggling power options have very little advantage. If not in use, you can turn off Bluetooth and Wi-Fi but don’t expect a significant jump in battery life.
The only sure way of getting more juice in such scenarios is to toggle the Airplane Mode on. This disables all radio functions on the phone and saves considerable battery.
