My trusty iPhone 7 is on its last legs. I bought it a year or two ago at the Apple Store in Hong Kong, but now, by noon, the battery is down to 10%. It’s clear I need a replacement. Sure, I could take it back to the Apple Store and get it replaced for around $49, which is less than it used to be. However, being in Shenzhen, China, the cell phone repair capital of the world, I knew I could find a better deal.

Shenzhen’s markets are legendary for their abundance of electronics and replacement parts, especially iPhone batteries. As I embarked on this adventure, I had two main questions: How can I tell if a battery is any good? And how can I distinguish a genuine battery from a fake one? I didn’t have the answers, but I was determined to find out.

Entering the Bustling Markets: A Quest for a Quality iPhone Battery

The vibrant, bustling markets of Shenzhen are a tech enthusiast’s dream, with countless stalls offering everything from phone cases to intricate electronics. But today, my focus was solely on finding a reliable iPhone battery replacement. As I wandered through the aisles, I was greeted with an overwhelming array of battery booths, each promising to have the best product on the market. But how could I be sure?

Battery Testers: The Key to Evaluating Quality

Almost every vendor had some sort of battery tester to check the battery’s condition before selling it. These testers are essential in determining whether a battery is as good as claimed. Seeing the importance of these devices, I decided to purchase a battery tester for myself to better understand the batteries’ quality. Armed with this tool, I felt more confident in navigating the maze of options available in Shenzhen.

After some browsing, I found a battery tester and a handful of batteries from different booths. Each battery was labeled with its booth of origin, whether it was claimed to be original or not, and its price. Additionally, I purchased two NOHON batteries from Taobao, a Chinese online shopping website, based on a recommendation from someone on Twitter. One was a standard capacity battery, while the other was a MAX battery, boasting higher capacity than the original iPhone batteries.

Evaluating the Batteries: Real vs. Fake

Using the battery tester, I began evaluating each battery. The tester could measure the cycle count, designed capacity, and actual capacity in mAh. It could also reset the cycle count to make a battery appear new—a feature that highlighted how tricky it can be to determine a battery’s true condition in these markets. Here’s a summary of my findings:

1. Battery from Booth 1: Cost 48 RMB (~$7). Claimed to be original, and the tester confirmed it. The battery showed a low cycle count and a capacity close to its designed specification, making it a decent option.
2. Battery from Booth 2: Cost 55 RMB. The vendor said the cable was original, but the cells were new. The tester labeled it as a copy but with a reasonable capacity, slightly lower than an original but still within acceptable limits.
3. Battery from Booth 3: An aftermarket brand DORAYMI, marked as a copy 1:1, but with higher than expected capacity. The tester indicated it was a decent battery, although the high capacity was a bit suspicious, possibly indicating reprogramming.
4. Battery from Booth 4: Claimed to be original and confirmed by the tester, though it had a cycle count of zero, which was suspicious. This could indicate the battery had been reset to appear new, a common trick in Shenzhen’s markets.
5. Battery from Booth 5: Cost 30 RMB. This was the first battery with a non-zero cycle count, indicating it had been used. Despite this, the capacity was still reasonable, suggesting it could be a good value option if the price is a concern.
6. Battery from Booth 6: Had the Apple logo scrubbed off on my request. Marked as a copy and performed adequately on the tester. The removal of the Apple logo suggested it was a decent clone, not an original, but still functional.

The NOHON Batteries: A High-Capacity Option

The NOHON batteries from Taobao were also put to the test. The MAX battery showed an impressive capacity, but the tester flagged it as non-original. The standard NOHON battery performed similarly to original batteries, offering a good balance between price and performance. These findings highlighted the variability in aftermarket batteries, with some offering genuine improvements in capacity while others were more dubious in their claims.

The Replacement Process: Installing the New Battery

After evaluating these options, I decided to replace my iPhone’s battery. Opening the iPhone was challenging due to the well-sealed gasket around the screen, and extracting the battery without breaking the adhesive strips required patience and care. Apple has designed its phones to be robust, but this robustness can make self-repairs tricky, especially without the right tools.

Discovering the Condition of My Old Battery

To my surprise, my old battery had 725 cycles but still maintained 85% capacity, suggesting it was in better shape than I expected. Despite this, I opted to install the NOHON MAX battery due to its higher capacity. The installation process involved carefully placing the new battery, ensuring it fit within the designated area, and reconnecting all the necessary components. After ensuring it fit and functioned correctly, I sealed the phone back up, albeit with some compromise on waterproofing. While this might not be a concern for everyone, it’s something to keep in mind if you’re planning on doing a DIY battery replacement.

Testing the New Battery: Performance and Longevity

With the new battery installed, I was eager to see how it performed. The NOHON MAX battery lived up to its promise, offering a longer battery life than the original. The increased capacity meant that my iPhone 7 could now last through the day without needing a recharge by noon. However, I remained cautious about its long-term performance, knowing that aftermarket batteries can sometimes degrade faster than official ones.

Shenzhen’s Markets: A Mixed Bag of Opportunities and Risks

Reflecting on this experience, it’s clear that Shenzhen’s markets offer a wide range of battery qualities and prices. You can find anything from branded aftermarket batteries like NOHON and DORAYMI to original Apple batteries, each with varying states of use and authenticity. This aligns with the broader perception of Chinese manufacturing: you get the quality you pay for, and it’s up to the consumer to discern what they’re buying.

For those looking to replace their iPhone batteries, the key takeaway is to buy from reputable sellers who test their products properly. Shenzhen’s markets can be a goldmine for tech enthusiasts, but they’re also filled with products of varying quality. Avoid random sellers with unknown histories unless you’re willing to take the risk. The battery tester I purchased was invaluable in helping me navigate these choices, but it’s not something the average consumer might have on hand.

DIY vs. Professional Repair: Making the Right Choice

The process of replacing an iPhone battery is quite straightforward and can be done at home with the right tools. If you’re technically inclined and have the patience, there’s little reason to visit the Apple Store for an out-of-warranty battery replacement. However, for those who prefer peace of mind and guaranteed results, professional services like those offered by Gadget Kings or iFixit might be a better option.

Reliable Alternatives: Why iFixit and Gadget Kings Are Worth Considering

For those seeking a reliable option, I recommend iFixit’s battery replacement kits. They offer a comprehensive kit with all necessary tools and a battery tested for quality. Their batteries are aftermarket but claimed to match Apple’s quality. iFixit’s customer support and repair guides are invaluable resources for DIY repairs. Until the end of 2019, they committed to keeping their battery kits priced at $29, even though Apple raised their replacement price to $49. iFixit’s transparent business model and dedication to customer satisfaction make it a trustworthy alternative to navigating the complexities of Shenzhen’s markets.
