Hi Mi Fans,
Users go to some strange measures to keep their batteries going and going and going. Yet much of what we hear about mobile batteries is simply not true. Let's examine some of these misconceptions about the batteries that power the devices we depend upon day in and day out.

Let's start from begin,

What is Battery?
The mobile phone has become integral to the modern world, both for professional and personal use. It would be impossible to imagine a world without them now, not only due to their importance at providing us with the ability to communicate on the move, but due the range of other features they provide. While there are still some basic models available that offer only basic functions, newer iterations are essentially multi-purpose gadgets, providing access to email, the ability to surf the Internet, watch videos, play games, and do a host of other things. This has only been advanced by the growth of the app industry: now it is possible to customize any phones to deliver an enormous range of tools that were previously unavailable. These advancements in mobile phone technology, however, have necessitated huge improvements in battery technology to power them. Since many of these features and functions drain battery power quickly, batteries now need to be longer lasting and more powerful than ever before. Moreover, with phone designs getting sleeker, and with the world becoming more concerned about the environment, batteries also need to be smaller, lighter, and made from less toxic materials.

Modern History of Batteries
Smartphones revolutionized today’s modern cell phone
Fast forward to the year 2012 when just about everyone has a smart phone. Compared to that first primitive cell phone back in the 1950s, the Smartphone is like science fiction or something out of Star Trek! You can call a friend, do a video chat, download your favorite tune, send a text or even make a reservation for dinner while you order up some flowers and chocolates to have delivered to your date. Batteries too have come a long way from the cell phone being tied to a car battery. Over the past few decades there have been several types of cell phone batteries.


Nickel Cadmium Cell Phone Batteries
Nickel Cadmium Batteries or Nicd were the batteries of choice during the 1980s and 90s. The main problem was that they were bulky and heavy, so that made the cell phones themselves end up large and bulky. Plus, after you recharged them a few times, they built up what is called a memory effect and didn’t always hold a charge. That caused dead cell phone batteries and that meant having to buy more and spend increasing amounts of money doing so. These batteries also had a tendency to get hot, which caused disturbances, plus one of the ingredients in the batteries was cadmium, which is toxic and is a problem to dispose of after the battery dies.

Nickel Metal Hydride Batteries
The next round of cell phone batteries were Nickel Metal Hydride, otherwise known as Ni-MH, which began in use during the later 1990s. It was non-toxic and had fewer problems with the memory effect issues. Plus, it was a thinner battery that weighed less, could be recharged in a shorter timeframe, and let users talk longer before they died. Lithium Ion Batteries Next in line were the lithium Ion batteries, which are still in use today. They are thinner and lighter still and last the longest of the others as well. Plus, it takes even less time to charge them too. They can be made into many different shapes and sizes to fit different styles of cell phones so any company can use them in their mobile devices. Plus, there is NO memory effect to worry about, so they last longer and can be recharged multiple times. They are also safe for the environment, unlike the earlier cell phone batteries. They are, however; much more expensive than the older battery models, but that is the trade off for a more efficient cell phone battery.

Lithium Poly Ion Batteries
The newest addition to the cell phone battery is the lithium poly icon or the Li-Poly battery, which has 40 percent more power than the old NiMh batteries. Plus, it is super light, and has no memory effect issue to cause charging problems. However, these batteries are not commonly used as yet, and are still pretty rare for now. All in all, both the technologies for the cell phone and its battery have come a long way in a relatively short period of time. What does the future bring for this technology? Only time and the innovative ideas of future scientists will tell.

How to Buy Mobile Phone Batteries
The best way to buy a new or replacement mobile phone battery is by choosing a direct replacement from the manufacturer who made the phone. There are several options available: For more details visit : Mi Support


OEM Batteries
OEM stands for original equipment manufacturer, and this essentially means that the battery will be made by the same manufacturer who made the original phone or battery. When buying a replacement battery, it is often sensible to buy them from a credible and reliable source. While the price might be slightly higher, the quality will be as well. In addition, these often come with warranties that will provide reimbursements or replacements for faulty products.

Non-OEM Batteries
Non-OEM batteries are those that aren't made by the manufacturer. Instead, they are made by different companies and may, therefore, have been produced using lower quality materials. As such, these batteries may come with lower charge capacities and life spans, but will generally cost less as a result. h3>Grade A or Refurbished Batteries
When mobile phones are returned to the network, the batteries are taken out and replaced. These batteries can then be sold on as new, often at lower prices than 'brand new' batteries. In the majority of cases, these will be of a high quality, and will often never have been used, making them good options for those looking to save a bit of money. As mentioned before, different phones brands and types will use different batteries. As such, it is important to get in touch with the phone manufacturer to make sure that any battery is actually compatible with the phone it will be used with. When buying batteries, this should be listed in the description.

Conclusion
Mobile phones are integral to our lives, and they cannot operate without batteries. While some battery technologies, such as nickel cadmium, are becoming obsolete, others are thriving, providing us with smaller, lighter, safer, more powerful, and more environmentally friendly options. As phones get more advanced, so too do batteries, and while this may force prices up, it also helps to provide longer lasting and more efficient products. When choosing batteries, buy them new if possible, and try to opt for OEM batteries as well. These will have a guarantee of quality, will generally last longer, and will provide a higher charge capacity than batteries made by unofficial manufacturers.


Some of the frequently asked questions & answers
Q1. Off-brand chargers will damage your battery
A: Although some off-brand chargers aren't optimal (and some even take longer to charge the battery), they will not harm it, as long as the charger is working properly. This means it's perfectly okay to run to Target and buy that cheap charger to replace the factory charger that came with your phone. The one exception to this is the charger that shipped with your Droid Turbo. Make sure, when looking for a replacement, you find one made specifically for that device; otherwise, you won't enjoy the 15-minute charge time that delivers eight hours of usage.

Q2. Charging your phone overnight will damage your battery
A: False. Most smartphones are now "smart" enough to know when a battery is at capacity and will stop charging. However, there is one thing you can do to extend the life of your battery. Instead of charging your phone all night, every night, try keeping it charged between 40% and 80% most of the time. This will ensure the longest possible life from that battery. If you can leave it unplugged overnight (every so often)

Q3. Using the internet will run down the battery faster than anything else
A: Not true.* The single most draining thing you can do on your smartphone is gaming. The graphics engines are massive energy drainers. If you game a lot on your devices, dim the screen as much as you can while playing (if you want to extend your battery life). But if you can play that game while charging, go ahead and keep that screen at full brightness.
* This also depends upon what you are using the internet for. If you're viewing videos through YouTube, online gaming, or doing other graphics-intensive activities, it will drain your battery faster.

Q4. Turning off Wi-Fi, Bluetooth, and GPS will prolong your battery
A: In and of itself, this is false. The only time these services actually drain your battery is if they are in use. So having Bluetooth turned on, when you're not using a Bluetooth device, isn't going to drain your battery any more than having Wifi on when you're not accessing the network. Yes, they may pull an insignificant amount of energy from your battery, but they will not drain it over the course of a day. If you're really concerned about getting as much life as possible from your battery, dim your screen.

Q5. Task managers help prolong your battery life
A: The third-party task managers do nothing for battery life that the built-in system can't handle. Yes, those task managers can whitelist/blacklist tasks. But in the end, they really don't help your battery any more than the built-in system. You might want to employ a task manager to better control your apps, but don't assume that third-party manager will extend the life of your battery any better than the default tool.
