If your device is not charging correctly than you may need an iPhone battery replacement. To diagnose a bad battery the iPhone now has a built in app that gives feedback about battery performance. There are many myths about how long a battery will last and most are incorrect. The typical lifespan of an iPhone battery is a thousand charge cycles. Every time you plug the device in to charge it counts as a charge cycle. If you need an iPhone battery replacement there are many options.
Recently Apple admitted that its operating software update affected the iPhone 6 and 6+ battery performance. They even had to offer a reduced iPhone battery replacement price to appease many of their customers. When Apple designed the iPhone they never entertained the idea of maintenance instead they encouraged employees to sell new phones. Many iPhone customers replace their devices within two years so that’s why there is no maintenance plans.
In order to perform an iPhone battery replacement you must be careful when removing the old battery. The lithium battery is very dangerous and can ignite quite easily if gets punctured or is overheated. Every iPhone uses the same type of battery which are lithium-ion polymer battery. These types of batteries are present in almost any devices that uses “rechargeable batteries” and are very reliable. When you complete an iPhone battery replacement you are replacing the old lithium battery, not recharging it.
When the iPhone was designed Apple intended the battery to last for a thousand charge cycles. What that means is if you plug your phone in to a power source it’s considered one charge cycle. The more you plug the device in the more charge cycles you’ll accumulate. So the best practice is to charge the batter fully so you don’t need to plug it in more than once per day.
