Charging habits to maximize battery life

Charging habits to maximize battery life

Hi guys welcome to ZX Android Solutions, Today we will discuss on "How to maximize our smartphones battery life".

Now a days smartphone's battery is an issue now. SmartPhone users are forever in search of longer battery life. While fast charging keeps us topped up every day, the absense of replaceable batteries means eventually the lithium-ion cell enclosed in our phones are going to age and deteriorate.

If you've held onto a phone for a year or more, you've probably notice the battery doesn't seem to last long as it did when it was brand new. Tow years down the line and many phone struggle to make it through the day on single charge. Holding onto a phone past three years can even spell trouble for system stability.

Unfortunately, Battery capacity inevitably declines with age. However, there are things you can do to prolong the life of your battery and handset. If you've ever wondered what the best way to charge your battery is, here are some scientifically proven tips for maximizing battery life.

Partial charging is the way to go

One particularly persisitant battey myth is that you need to occasionally fully discharge and recharge to erase "battery memory". This couldn't be more wrong for lithium-ion batteries. It's a leftover myth form lead-acid cell and it's actually quit undesirable to charge your modern smartphonein this way.

Partial charging is just fine for lithium-ion batteries and can actually have some positive benifits for cell longetivity. When closer to empty, Li-ion batteries draw constant current and operate at a lower voltage. This voltage gradually increases as the cell charges up, leveling off at around a 70 percent charge before the current begins to fall until the capacity is full.

Partial charging  is fine for lithium-ion battries rather than lithium polymer battries

Operating at a low voltage is good for a battery’s lifespan, increasing the number of available charging cycles before you’ll start to see a major reduction in capacity. Every 0.1V decrease in cell voltage doubles the battery's life cycle. Therefore, charging up your phone in that 30 to 80 percent range keeps the voltage lower and prolongs the battery lifespan.

the “depth-of-discharge” has a similar effect on the total discharge cycles before battery capacity drops off. This refers to the amount the battery used up in between charges. Smaller discharges, in the region of 60 percent rather than 100 percent between refueling can double the lifespan of your battery, and only using 20 percent can double the life again.

Top-Ups chargings are much better then long Full charge for SmartPhones battery.

Using up just 20 percent of your battery between charges isn’t going to be practical for most people, but topping up when you’ve used about half will see a notable improvement in your battery life over the long term, especially if you avoid charging up to full each time too. The bottom line is that small regular top-ups are much better for Li-ion batteries than long full charge cycles.

>> In easy language I want to say that don't charge your phone's battery at once it takes a long time and in this time space the temperature of battery gets high which reduces the battery life span. In case charge it like an installment if you want to.

Charging overnight or in a cradle during the day is a very common habit, but it’s not recommended for several reasons. First, continuous trickle charging of a full battery can cause plating of the metallic lithium, which reduces stability in the long term and can lead to system-wide malfunctions and reboots. Secondly, it leaves the battery at the higher stress voltage when at 100 percent. Third, it creates excess heat caused by wasted power dissipation. This may damage your battery and you may have to pay  for it.

Continuing to charge even when it is at 100% cause high voltage and temperature stress

Ideally, a device should stop charging when it reaches 100 percent battery capacity, only turning the charging circuit back on to top up the battery every now and again — or at the very least reducing the charging current to very small amounts.

I've even tasted some phones and noticed that even after 100% charging the phone keeps the charging cycle at half of the chargers voltage.

Gaming or watching videos while charging is bad as the distort charging cycle

The best way to avoid parasitic loads it to turn your device off while charging. But it’s probably more realistic to keep the workload very light while the device is plugged in, leaving it to idle most of the time. Remember to unplug it once it topped the charging scale.

Heat is enemy of battery life

A cell kept between 25 – 30 degrees Celsius (77 – 86 degrees Fahrenheit) should retain around 80 percent of its capacity after the first year even when cycling from empty to full charge. Battery capacity will be higher than this after a year if smaller periodic charging cycles are used. Raising the temperature to 40C (104F) sees this fall to just 65 percent capacity after the first year, and a 60C (140F) battery temperature will hit this marker in as little as three months.

A battery dwelling in a full state-of-charge exposed to a high temperature is the worst of all worlds and the number one thing to avoid when charging your phone. So no leaving your phone under your pillow to charge at night or plugged in on the dashboard of your car on a hot day.

Fast charging technologies are a contentious issue here, as the higher current and voltages can definitely lead to a hotter device while charging. Fast charging was never really envisioned for full-cycle charging though, instead, it’s a fast way to top up your phone quickly to get it back in your hands. Leaving your phone to quickly charge up for 15 to 20 minutes won’t lead to major overheating problems, but I certainly don’t recommend using them for overnight charging.

Bringing this all together

Clearly smaller regular charge cycles and keeping your phone cool are the key things to remember.

So, Whats the best way to charge your SmartPhone:

• Avoid full cycle (zero-100 percent) and overnight charging. Instead, top-up your phone more regularly with partial charges.
• Ending a charge at 80 percent is better for the battery than topping all the way up to 100 percent.
• Use fast charging technologies sparingly and never overnight.
• Heat is the battery killer. Don’t cover your phone when charging and keep it out of hot places.
• Turn your phone off when charging, or at least don’t play games or watch videos to avoid mini-cycles.
