FAQ About Phone Battery

The battery  is the most important component in your smartphone, because if the battery isn't working, nothing else can. With the right sort of care and attention, you can make sure your battery stays charged for longer—and lasts longer overall, as well.There is good news, which is the lithium-ion batteries inside today's phones are more reliable, longer-lasting, and safer—well, mostly—than ever before. That said, we've got some tips for keeping them healthy and happy.Top It OffThe chemical reactions inside lithium-ion batteries are more comfortable with shorter charges and discharges, rather than being drained all the way down and then topped all the way up.You're not going to seriously damage your phone if you wait for it to die every time before plugging it in again, but you do run the risk of shortening the battery's life. Keeping your phone between 50 percent and 80 percent seems to be the sweet spot. And whenever possible, try not to let it dip below 20 percent.On a related note, you're fine to leave your phone fully charged and connected to power overnight, or in the office during the day. Smartphones and chargers today can recognize when they've hit 100 percent, and accordingly reduce the flow of electricity to a trickle.Check the TempThe lithium-ion batteries inside your phone really don't like extreme temperatures, as you might have found on the ski slopes or the beach, when your phone has simply shut off in response to the chill or the heat.It's perhaps not reasonable to expect you to carry your phone around in a temperature-controlled vacuum chamber, but you can make sure it's well insulated in the cold, and not exposed to temperatures that are too high. Even simple precautions, like not leaving it in a warm car, can help.These temperature extremes won't necessarily kill your phone's battery for good, but they can hasten the natural degradation that all batteries suffer over time, meaning you'll need to replace it—or your phone—sooner than you otherwise would. Slow and SteadyWireless charging is very convenient. The various fast-charging technologies out there are very handy when you're pushed for time. But for battery longevity, consider using a standard charger, or charging via a laptop USB port, when you can.It's not that wireless charging or fast charging are inherently bad or that they're going to send your phone up in flames. But lithium-ion batteries definitely prefer a slow and steady input. Consider using the slow and steady approach whenever it's available.If you do rely on wireless charging or fast charging, make sure you're using the official charger that came with your phone, or an officially approved third-party accessory. These chargers will be configured to keep your phone battery as healthy as possible for as long as possible.Meet in the MiddleIf you're not going to be using your phone for a while, storing it with half a charge is preferable to leaving it fully charged or fully drained. Even if the idea of stashing your phone away for a while seems preposterous, some people do keep spares around just in case. The advice applies to tablets as well, which you may use less frequently.Remember what we said earlier about temperatures as well; you want phones to be stored at room temperature if at all possible. Bear in mind that certain less well-engineered phone cases might have the knock-on effect of increasing the warmth your device feels, especially while charging.Again, these are best practices for maximizing battery longevity. You're not going to come back to a broken phone just because it was left in a drawer on a full charge. Stay Up to DateManaging battery life is a delicate operation, and it's something that iOS and Android are gradually getting better at. You shouldn't really need another reason to keep the software on your phone up to date, but if you do, this is it.Thanks to lots of proactive nudging by manufacturers, it's getting increasingly difficult to keep your phone out of date for long. Which is great, not just battery life but the security of your device,compatibility with other apps and hardware, and so much more. In fact, you should go ahead and turn on auto-updates everywhere you can.If you've been putting updates off, your phone's battery will be grateful for having them installed, improving efficiency and battery management along the way. iOS now includes a battery health monitor—under Battery in Settings—while Android users can download a tool like AccuBattery. A note on Apple's Battery Health setting: If you swap in a battery outside of official Genius Bar channels, it will tell you that your battery needs "service." It doesn't. That's just Apple's way of encouraging people not to risk faulty third-party service—which right to repair advocates have a thing or two to say about. Make It LastEvery battery has a finite life in terms of cycles; it's just the nature of the chemistry inside it. That means the fewer times you go from a full charge to an empty charge, the better, so maybe consider making a single charge last rather than carrying a portable charger around with you everywhere.The usual advice applies here: Reduce screen brightness, use headphones instead of the built-in speakers, and put your phone in airplane mode for as long as you can stand it. That will turn off connections to other devices and stop apps from constantly pinging for updates. And that advice goes double when you're in an area with poor signal strength. Your phone works harder to try and stay connected to a weaker signal, and drains the battery faster as a result.

 How to Define Battery LifeBecome familiar with battery fade and how the ready light can deceive the user.Folks have been using rechargeable batteries for over 100 years but this marvelous power source is still poorly understood. The battery is a silent worker that delivers energy until it quits of exhaustion and old age. It is more prone to failure than most other parts in a system. Much is expected but little is given in return. With a shorter life span than the host device, battery replacement becomes an issue, and the “when” and “what if” are not well defined by the device manufacturer. Some batteries are replaced too soon but most stay too long.A portable system works well when the batteries are new but confidence drops after the first packs need replacing due to capacity fade. In time, the battery fleet becomes a jumble of good and bad batteries, and that’s when the headache begins. Battery management mandates that all batteries in a fleet are kept at an acceptable capacity level. Packs that fall below a given threshold must be replaced to keep system integrity. Battery failure occurs most often on a heavy traffic day or in an emergency when more than normal service is demanded.Batteries exhibit human-like qualities and need good nutrition. Care begins by operating at room temperate and discharging them at a moderate current. There is some truth as to why batteries cared for by an individual user outperform those in a fleet; studies can back this up.Charging is generally well understood, but the “ready” light is misconstrued. Ready does not mean “able.” There is no link to battery performance, nor does the green light promise full runtime. All batteries charge fully, even if weak; “ready” simply means that the battery is full.The capacity a battery can hold diminishes with age and the charge time shortens with nickel-based batteries and in part also with lead acid, but not necessarily with Li-ion. Lower charge transfer capability that inhibits the flow of free electrons prolongs the charge time with aged Li-ion.A short charging time propels faded batteries to the top, disguised as combat ready. System collapse is imminent when workers scramble for freshly charged batteries in an emergency; those that are lit-up may be deadwood. (Note that the charge time of a partially charged battery is also shorter.)  Figure 1 shows the “ready” light that is known to lie.  The amount of energy a battery can hold is measured in capacity. Capacity is the leading health indicator that determines runtime and predicts end of battery life when low. A new battery is rated at 100 percent, but few packs in service deliver the full amount: a workable capacity bandwidth is 80–100 percent. As a simple guideline, a battery on a two-way radio having a capacity of 100 percent would typically provide a runtime of 10 hours, 80 percent is 8 hours and 70 percent, 7 hours.The service life of a battery is specified in number of cycles. Lithium- and nickel-based batteries deliver between 300 and 500 full discharge/charge cycles before the capacity drops below 80 percent.Cycling is not the only cause of capacity loss; keeping a battery at elevated temperatures also induces stress. A fully charged Li-ion kept at 40°C (104°F) loses about 35 percent of its capacity in a year without being used. Discharging is also harmful. This cuts battery life to half, and hobbyists can attest to this.*** Please Read Regarding Comments ***Comments are intended for "commenting," an open discussion amongst site visitors.

Weare a trade and industry company.

                             Is the capacity of mobile phone battery as big as possible? The capacity of the battery is limited by the size of the cell, and the current cell manufacturing technology has not been able to improve the cell capacity substantially.

Should the new phone be recharged? Under normal circumstances, a new cell phone is generally with some power, but a lithium-ion battery in place after a period of time will enter a dormant state, so a lot of people think the new phone need to recharge after 12 hours, just to be able to use, but now the mobile phone is the lithium batteries are used almost no "memory effect", so just standard charge "natural activation" is ok, just after 3 ~ 5 times of the normal charge and discharge, battery returned to normal capacity, long time not activate lithium battery power supply is connected, but produce huge damage to the battery itself;Usually, the mobile phone manual to introduce the charging method, is the most suitable for mobile phone battery charging method.

                                        What is the focus of purchasing mobile power? 1. Cell capacity.The cell capacity marked by the merchant when selling mobile power supply is not consistent with the actual cell capacity, and there is the suspicion of selling unqualified products as qualified products.2. Flammability of shell.Many mobile power supply cases on the market are made of plastic, which is a flammable and flammable material, which may cause safety risks.3. Heavy impact.In life it is possible to move the power supply on the table fall, may cause the impact of the battery, the standard requires that the battery should not be affected by the impact of fire, not explosion.

                          How to make the phone last longer？ 1.Turn off WiFi when you run out of WiFi. Now most people are using WiFi, so some people will keep WiFi on all the time.It will constantly search for signals and lose power. 2.Reduce the screen brightness, now the mobile phone screen is getting larger and larger, the need for electricity is more, so, in ordinary use, try to reduce the screen brightness, also has a great role in battery life. 3.Turn off GPS, bluetooth and other auxiliary functions. For GPS, bluetooth and other auxiliary functions, they can only be turned on when they need to be used. If the phone is turned on by default, it should be turned off manually. 4.Do not use dynamic desktop, there are many dynamic wallpaper, also very cool, but if you want to save power, try not to use dynamic desktop.

How to Prime BatteriesDiscover what a battery needs to get going and maintain a long life.In many ways, a battery behaves like a human being. It senses the kindness given and delivers on the care given. It is as if the battery has feelings and returns on the benevolence bestowed. But there are exceptions, as any parent raising a family will know; and the generosity conferred may not always deliver the anticipated returns.To become a good custodian, you must understand the basic needs of a battery, a subject that is not taught in school. This section teaches what to do when the battery is new, how to feed it the right “food” and what to do when putting the pack aside for a while. Chapter 7 also looks into restrictions when traveling with batteries by air and how to dispose of them when their useful life has passed.Just as a person’s life expectancy cannot be predicted at birth, neither can we date stamp a battery. Some packs live to a great old age while others die young. Incorrect charging, harsh discharge loads and exposure to heat are the battery’s worst enemies. Although there are ways to protect a battery, the ideal situation is not always attainable. This chapter discusses how to get the most from our batteries. Priming a New BatteryNot all rechargeable batteries deliver the rated capacity when new, and they require formatting. While this applies to most battery systems, manufacturers of lithium-ion batteries disagree. They say that Li-ion is ready at birth and does not need priming. Although this may be true, users have reported some capacity gains by cycling after a long storage.“What’s the difference between formatting and priming?” people ask. Both address capacities that are not optimized and can be improved with cycling. Formatting completes the fabrication process that occurs naturally during use when the battery is being cycled. A typical example is lead- and nickel-based batteries that improve with usage until fully formatted.  Priming, on the other hand, is a conditioning cycle that is applied as a service to improve battery performance during usage or after prolonged storage. Priming relates mainly to nickel-based batteries. Lead AcidFormatting a lead acid battery occurs by applying a charge, followed by a discharge and recharge. This is done at the factory and is completed in the field as part of regular use. Experts advise not to strain a new battery by giving it heavy duty discharges at first but gradually working it in with moderate discharges, like an athlete trains for weight lifting or long-distance running. This, however, may not be possible with a starter battery in a vehicle and other uses. Lead acid typically reaches the full capacity potential after 50 to 100 cycles. Figure 1 illustrates the lifespan of lead acid. Figure 1: Lifespan of Lead AcidA new lead acid battery may not by fully formatted and only attains full performance after 50 or more cycles. Formatting occurs during use; deliberate cycling is not recommended as this would wear down the battery unnecessarily.Deep-cycle batteries are at about 85 percent when new and will increase to 100 percent, or close to full capacity, when fully formatted. There are some outliers that are as low as 65 percent when tested with a battery analyzer. The question is asked, “Will these low-performers recover and stand up to their stronger brothers when formatted?” A seasoned battery expert said that “these batteries will improve somewhat but they are the first to fail.”The function of a starter battery lies in delivering high load currents to crank the engine, and this attribute is present from the beginning without the need to format and prime. To the surprise of many motorists, the capacity of a starter battery can fade to 30 percent and still crank the engine; however, a further drop may get the driver stranded one morning. If you have a suggestion or would like to report an error, please use the "contact us" or email us at: jwt_gz@jinweite.net .We would like to hear from you, or we recommend posting your questions in the comments sections to share.  Thank you ! 

Smartphones are good, but there is one problem that is almost unanswered: need to charge. And then high-end smart phones, once no electricity, and a piece of fragile floor tiles no difference. Let us can not help but take a look at both eyes, and depressed back,...So, the question is, how much charge left when the phone charge is better? How to charge the phone more secure and effective, without damaging the battery, so smart phones live longer?How do you usually charge?For many people, charging is a matter of course: before going to sleep to charge the phone; any place to see the plug socket to charge the phone; even charge a treasure anywhere to recharge the phone; sit in front of the computer will be inserted in the phone Charge on the computer.As for the phone how much power and then take to charge ... ... Keke, it depends on how much last remaining power. However, there are many people in the power left 20% or 15% to start warning, hurriedly jumped up looking for a charger.How much battery charge the best?You must have noticed such a problem: the speed of phone charging is not constant. Sometimes it takes a while for a while to recharge, and sometimes for a whole day and night. So, when charging the fastest it?In general, a battery that is almost depleted is like a man almost trapped in the desert, dehydrated, and as soon as he is brought into contact with the water he draws the most moisture as quickly as possible. Similarly, when the battery is almost consumed by the amount of power to charge it to achieve better charging efficiency. So when the battery is left with 10% of the charge left, it is possible that it will receive a higher current than the 50% charge left.However, if the charge is low as mentioned above, then charge your cell phone battery suffer!What are the hazards of incorrect charging methods? In everyone's concept, the battery used to recharge the following 20% ​​will be better, in the era of nickel-metal battery is true. But to the present era of lithium batteries, so that the phone power down to 20% or even automatically shut down, the battery is very large damage, can cause slow charging, the battery is not used, and even reduce the battery life and other issues.In addition, if the phone is used to automatically shut down, the lithium battery will be too much discharge due to internal voltage is too low, there may be unable to turn on and charge!How much charge left the best charge?Each battery has a number of charging cycles, charging the number of runs out, it means that the battery should come to an end.A charge cycle means that the battery is fully used up from full charge to full charge, so if your poor cell phone always runs out of charge before it is fully charged, the life of the battery is drastically reduced. Therefore, as much as possible to keep the battery more than 50% of the charge, once below this charge, it should be charged to the phone.Mobile phone over-charging there is a problem? We all know that lithium batteries generally have safety circuits and a lot of safety full-time, sufficient to ensure that the battery is automatically cut off during over-power. Therefore, under normal circumstances overcharging will not lead to safety issues such as explosions.However, after the battery is fully charged, the battery will remain charged at full charge, which will speed up the loss of battery capacity and reduce the battery capacity. Battery is the lifeblood of the phone, please protect it. Do not let the battery has been in a state of charge, do not wait for no power off and then rushed out to charge the phone, do not use the phone at very high or very low temperature, do not let the phone can not quickly charge fast charging, slow is Fast, so your love machine can play a greater performance, you say?

For netizens who rely heavily on smartphones, it is likely that cell phones (games, movies, ...) are almost exhausted every night before going to bed, and then plug the phone into the charging cable and finally fall asleep. But have you ever heard of "cell phone charge all night, will hurt the battery life" argument? In the end, how to do it is correct?Business Insider quoted a report from Battery University's Web site at Codex Battery Corp. that every time a cell phone lithium battery is charged to 100%, the voltage of the lithium cell reaches its peak twice. And if the night charge the phone all night, because part of the phone is not completely cut off the battery and the power connection, equal to the battery has been maintained at high pressure, the battery life will cause some damage.Recently, however, Business Insider also interviewed Kyle Wiens, the head of iFixit, which dismantled the iPhone and other electronic products, to overthrow the past. Kyle Wiens points out that "charging your phone all night long does not really affect battery life." Kyle said each battery has a fixed charge cycle, which means "the smart phone battery's integrity before it ages significantly Charging times ". For example, when a cellphone uses 50% of the charge and then charges, it will charge the phone in half and charge half the battery charge cycle.Kyle said that in general, smart phone battery charging cycle is about 400 (Apple's official saying, iPhone battery charging cycle is 500). This standard is to say, under normal use, the device can use about a year and a half or so. If properly maintained, the service life of more than a year and a half is also very possible.Why then there will be charged overnight battery rumors it? Because most of the early rechargeable batteries are nickel-cadmium batteries, such batteries have the memory effect of the defect, simply because the battery capacity will be reduced due to over-charge, causing you to leave a charge all night will hurt the battery impression.However, the current rechargeable battery to change more lithium batteries or lithium-ion battery, no memory effect will occur. Moreover, mobile devices in their hands have been cleverer than ever before. After fully charged, the processor or circuit board in the mobile phone will automatically switch over and rely on the power of the socket as the power source to ensure that when the user wakes up and picks up the mobile phone, The screen is 100% state of charge is completed, the excess current will not flow into the phone battery.So, you charge the phone for a full night, it will not change the battery charge cycle. Only when you use the phone (power), it will consume the battery charge cycle.However, when you charge the smart phone overnight, although the battery life will not cause much impact, but in fact the potential danger is indeed high, because the cell phone battery charging will be at a higher temperature, may result in lithium batteries Degradation, that is to say loss of stored energy of the active substance.If you want your cell phone batteries to maintain the best use of the state, it is best to keep the cell phone battery power between 10% to 90%, do not fully drain the power or fully charge it, and try not to phone in the extreme Temperature, such as snow or desert, in other words, the use of mobile phones is best to maintain the temperature between 0 ~ 45 degrees Celsius, because this range is lithium battery normal operating temperature range, more or less than may be on the battery The life of the damage.Phone fully charged, the best way to protect it or unplug the charging cable! But Xiao Bian that the most suitable method is ... ... how to facilitate how to charge, every day will worry about battery life will be a short period of one or two days, we ourselves will be over-worried because of short-lived, right?
