Smartphone technology has come a long way within the past few years. Smartphone manufacturers have been struggling to increase the battery capacity in their phones while keeping the phones thin and aesthetically pleasing. Nevertheless, most smartphone users are always looking for ways to extend the battery life on their phones. In this blog post, I will give you some battery charging tips for Android phones.
Fast charging is extremely convenient but it may decrease your battery’s lifespan. Many of the phones that are currently available on the market today do not have replaceable batteries.
As a result of this, the lithium-ion battery in your phone will age and deteriorate. If you’ve had your phone for over a year, you may have noticed that the battery does not last as long as it did when it was new.
This becomes more noticeable if you’ve had the phone for at least two years.
At this point, the battery capacity on many phones will have diminished and they may struggle to make it through a full day on a single charge.
It’s unfortunate that the battery capacity declines with age. Nevertheless, there are certain things you can do to extend the battery life on your phone.
I will give you some scientifically proven tips that will help you to maximize the battery life on your phone.
Battery Charging Tips For Android Phones:
Partial Charging Is Better:
When it comes to charging the battery on my cell phone people always told me from time to time I need to fully discharge my phone then recharge it to its full capacity to erase the battery memory.
However, this is incorrect, this was the method used to charge lead-acid cells. Lithium-ion batteries that are in our phones should not be charged this way.
Partial charging works best for lithium-ion batteries, doing this will increase the lifespan of the battery in your phone.
When a lithium-ion battery is almost empty, it operates at a lower voltage and draws constant current.
When you start charging the phone, the voltage gradually increases as the battery is charging and it levels off at about 70 percent charge.
Then the current starts to fall until it reaches full capacity.
Benefits Of Partially Charging Lithium-Ion Batteries:
When the battery operates at a lower voltage this is good for the lifespan of the battery.
This increases the number of charging cycles available before you start seeing a greater reduction in capacity.
According to Battery University, every 0.1V decrease in cell voltage will double the life cycle.
As a result of this, if you keep your phone within the 30 to 80 percent range, it will keep the voltage lower and prolong the lifespan of the battery.
Nevertheless, the depth of discharge has a similar effect on the number of discharge cycles before the battery capacity reduces.
The depth of discharge refers to the amount of battery capacity used between charges.
The smaller discharges around 60 percent instead of 100 percent when recharging may double the lifespan of your battery, and just using 20 percent will double the life span again.
Smaller Charging Cycles Are Better:
Using only 20 percent of your battery before recharging it will not be possible for most people.
However, you will notice an improvement in the battery life if you regularly recharge the battery after it reaches about 50 percent capacity.
When you’re charging your phone, it’s best if you do not charge it to its full capacity every time.
Shorter charging cycles on a regular basis are better for Li-ion batteries in comparison to long charging cycles.
Idle Charging Is Bad For Your Battery:
Many of us charge our phones overnight because it’s extremely convenient. However, this is a bad practice, there are three reasons why you should not do this.
- After the battery reaches its full capacity continuous trickle charging may cause plating of the metallic lithium. This may cause instability and it can lead to system-wide malfunctions and reboots.
- The wasted power dissipation causes excess heat.
- This will leave the battery at a higher stress voltage when its at full capacity.
More Reasons Why You Shouldn’t Continue To Charge Your Phone When It’s At 100%:
A modern-day smartphone has technology that is supposed to stop it from charging when the battery capacity reaches 100 percent.
The charging circuit is supposed to turn on from time to time if the battery capacity goes below 100 percent, the charging current should be reduced to small amounts.
However, it doesn’t always work out this way, tests have been done on phones that are fully charged and in many cases they continue to pull as much as half an amp from the wall outlet sometimes more.
It makes no difference whether the phone is turned on or off.
You Should Not Use Your Phone While It’s Being Charged:
Parasitic load takes place when the battery is being significantly drained while it’s being charged.
For example, if you’re watching a video, playing a game, talking to someone, surfing the net, or doing any other type of activity while the phone is being charged it’s bad for the battery.
This is bad because it distorts the battery’s charging cycle and mini-cycles. When this occurs, part of the battery will continually cycle and deteriorate at a faster pace than the rest of it.
It’s even worse when parasitic loads occur when the phone is fully charged because this causes higher voltage stress and it makes the battery heat up.
So you must try to avoid using your phone while it’s charging but this can be difficult if someone calls you or sends you a text message while your phone is charging.
The absolute best way to avoid parasitic loads is to turn off your phone while it’s charging but this may not be possible for most people.
So if you can’t turn your phone off while it’s charging and you must use it you should try to minimize the amount of time you spend using it while it’s charging.
You must remember to unplug the charger when the battery has been charged sufficiently.
Heat Is Extremely Bad For Your Battery:
Keeping your battery at the right temperature is very important and it will play a huge role in the lifespan of your battery.
When the battery is overheating it loses capacity at a much faster rate than when it’s kept at a lower temperature.
A cell that’s kept between 77 – 86 degrees Fahrenheit will most likely retain about 80 percent of its capacity after one year even if it’s cycling from 0 to 100%.
But the battery capacity will be a bit higher than this after one year if smaller charging cycles are used.
So if you raise the temperature to 104F the battery capacity will be 65 percent after one year and if you raise the temperature to 140F the battery capacity will be 65 percent in approximately three months.
A battery that’s fully charged that’s exposed to a high temperature is the absolute worse thing, you must avoid this at all cost.
We all appreciate fast charging because no one wants to wait a long time for a phone to charge.
However, the higher current and voltages that occur when fast charging can make your phone hotter while charging.
When fast charging was invented, it wasn’t meant to be used for full charging cycles. This was made to provide a quick and easy way to charge up your phone so you can use it again.
If you use fast charging for a small charge cycle for about 15 to 20 minutes, this will not cause your phone to overheat.
However, charging your phone for an extended period of time via fast charging is not good for your battery because it will overheat.
Only Use The Original Charger:
You should only use the original charger when charging your phone.
Try to avoid using third party chargers when charging because some of them use a higher voltage to charge the phone quicker.
However, this is bad because it will shorten the lifespan of your battery.
More Battery Charging Tips For Android Phones:
Most smartphone users are familiar with lithium-ion batteries, however, many of us have adopted some bad habits when charging our batteries.
For the most part, these habits will not have a severe negative impact on your phone’s battery life for short term use.
However, if you consistently do the wrong thing over a longer period of time, for example, one or two years.
The negative effect on your battery will be more noticeable, so you should do everything you can to maximize your phone’s battery life.
You should try to keep your phone cool at all times and use shorter charging cycles when charging it.
Different phone batteries will age differently, it all depends on how well you take care of them.
