Apple’s iPhone is performing really well with cutting-edge performance, premium design, and range of features. Apple’s iPhone 6s, launched back on 25 September 2015, is performing really well except one factor, which is battery performance. After one year of complete use, the iPhone 6s battery isn’t offering peak performance. There’s why you need to buy an iPhone 6s replacement battery. A replacement battery is a type of battery for use in place of an existing battery. It gives the same or similar operating and performance characteristics. We’d like to share a few quick, but important facts about iPhone 6s replacement battery with you right now before we proceed with the reviews:

  • Apple’s original batteries are designed to go through 500 charge cycles
  • Battery problems are quite common as your phone ages
  • In some cases, when the battery wears out, the phone also slows down

When Should You Change Your iPhone Battery?

If you’ve had your iPhone for awhile you may have noticed that it doesn’t last on one charge as long as it used to or that it’s slowed down considerably. Sound familiar? Well, it might be time to change your iPhone battery. Apple recently acknowledged that their lithium-ion batteries gradually lose their ability to maintain a full charge over time. After 500 charge cycles, the battery capacity can drop to 80% or even lower. At that point your iPhone may intentionally slow itself down in order to prevent your aged battery from failing.

How to know if your iPhone battery needs to be replaced

The best way to know if you need to replace your iPhone battery is by going to Settings > Battery > Battery Health. On this page, you will see a quick overview of your battery’s health via its “Maximum Capacity” and “Peak Performance Capability”.

“Maximum Capacity” is a measure of the battery’s capacity relative to when it was new. A brand new phone should read 100% and will reduce over time; the lower the percentage, the faster your battery will deplete on one charge.The “Peak Performance Capability” measure is more of a ‘Good’, ‘Not-so-good’ or ‘Bad’ scenario. If your phone reads “Your battery is currently supporting normal peak performance”, you are in the clear – your battery is up to par and there is nothing you need to do. On the other hand, if you see “This iPhone has experienced an unexpected shutdown… Performance management has been applied…” it’s a sign that your battery is experiencing some significant wear.

Circumstances you need to change your battery

Here are a few other ways to tell that your iPhone battery might need to be replaced:

  • If you’re having to recharge your battery every few hours, even when usage is low, it might be time for a new battery
  • When the phone unexpectedly dies when the battery is 10% or higher, this could be a sign of a battery worth replacing
  • If your iPhone only works plugged it, you guessed it – replace the battery
  • OR if you’re looking for more of a scientific approach, you can download an app like Battery Health which gives you a look into battery capacity, power usage, etc.
Note: There are some abbreviations used in the blog which might be difficult to understand. Down below are full form and a short definition for you’ll to have an easy understanding
  • UL: It stands for Underwriter Laboratories, a third-party certification company that’s been around for over a century. They certify products with the aim to make the world a safer place for both workers and consumers. UL testing makes sure that wire sizes are correct or devices can handle the amount of current they claim to be able to. They also ensure that products are constructed correctly for the highest safety.
  • ROHS: It stands for Restriction of Hazardous Substances Directive. Basically it certifies that there are few/no materials in a product that is on a list of known-toxic materials. Probably the biggest impact of this is the removal of lead-based solder from most recent electronics.
  • FCC: It stands for Federal Communications Commission. It is an agency of the United States federal government that was created to regulate all forms of telecommunication inside of the U.S. Including radio, television, digital cameras, Bluetooth, wireless devices, and a broad gamut of RF electronics. If it is an FCC certificate, it means the product has been tested to comply with FCC standards and it has been approved.
