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, andsafer—well, mostly— than ever before. That said, we've got some tips for keeping them healthy and happy. Top It Off The 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 Temp The 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 Steady Wireless 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 Middle If 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 Date Managing 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 Last Every 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.

What are the tips for charging mobile phones?  1. When charging, try to use the original charger to charge the phone. Using usb to charge the phone with low output current will prolong the charging time. 2. Reducing the power consumption of the phone itself during the charging process will make the phone charge more effectively. 3. When charging the phone, it is recommended to remove the protective case or the back cover of the phone, so that the battery can dissipate heat freely. 4. In the course of use, the lithium battery of the mobile phone should be properly maintained to keep the electrons of the mobile phone active. It is recommended to charge whenever you want, once a month.

What if there is no response to the charging of Nokia's mobile phone? Possible reasons: 1. The charger is not plugged in properly. 2, use the universal charge to make sure that the electric board is not broken. 3, battery aging. Solution: 1, change the universal charger to see if it is effective, if it is effective, it is certain that the charging AC adapter is broken. 2, if the above can not be charged, it must be that the electric board is broken, it is recommended to go to the mobile phone maintenance point or digital city with an electric board. 3, bring the purchase invoice to Nokia after-sales service point for maintenance.

                             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.

What certification do you have for power bank? CE,FCC,RoHS,MSDS                     

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? Cell Capacity. The cell capacity marked by merchants when selling mobile power supplies is not consistent with the actual cell capacity, raising suspicions of selling unqualified products as qualified ones. Flammability of Shell. Many mobile power supply cases on the market are made from plastic, which is a flammable material and may pose safety risks. Heavy Impact. In daily life, there is a possibility that the power supply may fall off a table, potentially impacting the battery. Standards require that the battery should not be affected by such impacts, preventing fire or explosion. Expansion: Regarding the issue of cell capacity, consumers should pay attention to product certifications and testing reports when purchasing mobile power supplies to ensure the authenticity of the products. It is also advisable to choose products from well-known brands, as they are more likely to provide accurate descriptions of battery capacity and undergo rigorous testing. Concerning the flammability of the shell, users should avoid placing mobile power supplies in high-temperature or direct sunlight areas to reduce the risk of fire due to overheating. Additionally, manufacturers should consider using materials that are heat-resistant and have lower flammability ratings when producing these casings to enhance product safety. Lastly, addressing the heavy impact issue, manufacturers should design sturdier cases and conduct drop tests to ensure that the battery remains undamaged during accidental drops in everyday use. Consumers should also handle their mobile power supplies with care, avoiding placement in areas where they could easily fall, thereby ensuring safety.

        How to make the phone last longer？ First, turning off WiFi when there is no network available prevents unnecessary battery drain from constant signal searching. Users may adopt a habit of regularly checking their WiFi status to ensure that it is turned off when not in use. Second, reducing screen brightness not only saves battery life but also alleviates eye strain. Utilizing night mode or automatic brightness adjustment features can further optimize battery usage, particularly in dimly lit environments. Regarding the disabling of GPS and Bluetooth, many applications continue to run these functions in the background, leading to rapid battery depletion. Manually turning off these features when they are not needed is a wise choice. Lastly, while dynamic desktops can enhance aesthetics, they incur considerable battery consumption. Opting for static wallpapers can save power while providing users with a cleaner and clearer interface experience. By following these tips, users can maximize their smartphone's battery life and enjoy a more efficient mobile experience.

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. 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 !
