How do I make sure my phone’s battery lasts as long as possible?
Most of us never think about the battery in our phone until it dies. When everything is working properly the battery should not be a part of the Android experience, other than not lasting long enough because we never put our phones down. The only time we ever think about the battery is when we have to charge it.
How you do that charging can make a difference, though not nearly as much as some people think. Let’s have a look at the right way to take care of your battery and if it really matters.
Charging at night
If you plug your phone in when you go to bed and let it charge all night, it still won’t overcharge the battery. But it’s important to mention that you should never charge a lithium-ion battery unattended.
When the phone is fully charged the electronics in the battery tell your phone to stop sending electricity from the charger to the battery charging circuit. Power still comes in, it just doesn’t work at recharging anything and goes back out to the wall socket (electricity travels in an unbroken loop to and from the power source). If your phone is still powered on the battery will discharge because it’s being used. When it discharges to a certain point, charging starts again. This cycle repeats until you unplug it in the morning.
A lot of work was done to make sure the cell inside the battery doesn’t overcharge at any time. Even during the night while it’s on the charger. If you’re going to charge your phone overnight, make sure everything works properly and you’re charging properly. That means you don’t have the phone under a blanket or laying on the rug while it’s plugged in or have it in a thick sealed case that keeps the heat in. Plug it in (or put it on a wireless charger) somewhere that it won’t get tangled up in your bedclothes or knocked to the floor.
Using another charger
Always try to use the charger and cable that came with your phone each and every time you need to charge it. If you need a replacement or an additional charger, buy the type the manufacturer recommends. Products are designed so that the different types of quick charging products can be used on phones that don’t support them (you won’t get fast charging speeds) but it’s still advisable to use the right quick-charge technology. If you’re unsure of which kind of quick charging your phone uses, online resources like our forums are helpful, or you can contact the manufacturer.
It’s also a good idea to buy new cables when you buy a new phone. Always. Charging technology change so fast that the cables you have been using for a few years might not meet the requirements and cables degrade from all the twisting and pulling they suffer through. Make sure the cables you buy match the specifications of the ones that came in the box and are made by a company you trust. Recycle your old cables and protect your expensive new phone.
Our recommended practices
+ Charge your phone when it needs a charge and remove it from the charger when it’s finished.
+ Don’t be afraid to use a wireless charger. Use quick charging sparingly if you’re concerned about its effect on battery lifespan.
+ There is little immediate damage or danger from using the right charging method for your phone.
+ Try to manually shut your phone off if the charge ever drops below 10% and leave it off while charging it for a few minutes. Never store a phone with a dead battery and check on a stored phone periodically.
+ Don’t buy cheap chargers or cables from the gas station or that dude at the flea market.
+ Use the type of charger the people who made your phone recommend.
+ You can make yourself crazy by worrying about the perfect way to charge your phone’s battery.
+ All the technical details about how behaviors can affect the lifespan of the battery are true, but they are also very minor in scale.
+ Charging and discharging a battery shortens its lifespan, but a battery is useless if it’s not charged so it can power something.
It’s OK to baby your phone’s battery, but ultimately not necessary.
