My Buying Guide on iPhone 8 Plus Battery

When I decided to buy a new battery for my iPhone 8 Plus, I quickly realized there are several factors to consider. I wanted to ensure I made the right choice without overspending or compromising on quality. Here’s what I learned along the way.

Understanding Battery Life

First things first, I needed to understand the importance of battery life. My iPhone 8 Plus has been a trusty companion, but over time, I noticed that its battery life wasn’t what it used to be. Apple states that the iPhone 8 Plus battery can last up to 21 hours of talk time and 13 hours of internet use. When my usage started to dwindle, I knew it was time to consider a replacement.

OEM vs. Aftermarket Batteries

One of the most critical decisions I faced was whether to choose an OEM (Original Equipment Manufacturer) battery or an aftermarket option. I learned that OEM batteries, like those from Apple, are generally more reliable and often come with a warranty, which gave me peace of mind. However, they can be pricier. On the other hand, aftermarket batteries are usually cheaper, but the quality can vary significantly. I opted for an OEM battery to ensure longevity and performance.

Checking the Battery Capacity

When I started my search, I made sure to check the battery capacity. The original battery for the iPhone 8 Plus has a capacity of 2691 mAh. I focused on batteries that matched or exceeded this capacity. This way, I could be confident that I was getting a battery that could hold a charge effectively.

Warranty and Return Policy

Another aspect I paid close attention to was the warranty and return policy. I prefer to buy from reputable sellers who offer at least a 6-month warranty. This provides a safeguard if the battery doesn’t perform as expected. I also looked for sellers with a good return policy, just in case I needed to exchange it for any reason.

Installation Considerations

I realized that installation could be a significant factor in my buying decision. I’m reasonably handy, but I didn’t want to risk damaging my phone with a complicated installation process. Some batteries come with installation kits and guides, which made the process easier. If you’re not comfortable doing it yourself, I recommend considering professional installation.

Price Range

While shopping around, I noticed a wide price range for iPhone 8 Plus batteries. OEM batteries typically fell between $50 to $100, while aftermarket options could be found for as low as $20. In my experience, I found that spending a little more on a quality battery was worth it in the long run. I aimed for a balance between quality and price.

Reading Reviews

Before finalizing my purchase, I made sure to read reviews from other customers. This step was crucial as it helped me gauge the reliability and performance of the batteries I was considering. I found that many online retailers like Amazon and specialized electronics stores provided customer feedback that was incredibly helpful.

buying a battery for my iPhone 8 Plus was a task that required careful consideration of various factors. By focusing on OEM versus aftermarket options, checking capacity, understanding warranties, and reading reviews, I felt confident in my choice. Whether you’re in a similar situation or just looking for a battery upgrade, I hope my experiences help guide you in your decision-making process!
