There is always a lot of talk regarding the battery life of your phones, most being negative comments. It’s understandable too, I mean there is nothing worse than your device running out of battery in the middle of the workday. However, it’s tricky to tell the scientifically based “battery saving tips” from the plethora of nonsense.
I SHOULDN’T CHARGE MY PHONE OVERNIGHT: FALSE
We come across this rumour a lot, but this is false. Phones do not overcharge anymore in 2021. This particular myth does have some scientific proof to it, but that is from a few years ago. Years back, Lithium-Ion batteries did heat up if charged too much. However, modern devices are way smarter. They gradually reduce the amount of power going into the phone as it fills up, completely cutting off once it reaches 100% charge and occasionally trickles charging to maintain a 100% battery life.
MY BATTERY SHOULD ALWAYS DROP TO ZERO BEFORE CHARGING: FALSE
Letting the battery drop down to zero before charging again, in fact, wears out the battery even more as more battery cycles take place during this process. Partial discharge is the way to go. It’s recommended that it is better to charge your phone once it reaches 20% or 30% rather than less than 10%.
THE BEST THING TO DO:
Charge your phone once it reaches 30%, and stop charging before it reaches 90%. Ideally, always keep your phone between 30% to 80%. This avoids any strain on your battery and gives it a longer lifespan.
Overall, just don’t worry too much. Batteries are designed to be used under some strain (not in excess) and they will degrade over time at the end of the day.
