Do Battery Chargers Ruin the Battery Life of Your Phone?

Most cell phones require a wall charger or portable charger to offer a voltage of around 5V. However, if you’ve ever trawled through questionable eBay listing or spend time in a market with goods of dubious quality, you may have encountered knockoff portable chargers.

Perhaps that’s why some commentators have their battery was damaged.

While this doesn’t mean you need to or should leave them plugged in all the time, it means that even if your phone is plugged in while it is fully charged, these portable chargers aren’t overcharging your device or draining the long-term battery life.


Why Do Charge Cycles Can Affect Battery Performance?

One other reason for some people to feel like there cell phone’s battery is weakening is not because of the charger used but because of the amount of charges. In general, a typical lithium battery will have at least 500 full cycle charges.

Repeated chargers will eventually render your device to never be able to get that full charge it was once able to. So if you fully charge every day for a year and a half, your battery will exceed 500 charge cycles and will be start to noticeably perform worse. Luckily most phones have replaceable batteries.
