The best iPhone 6 replacement battery should make your phone even better.
The iPhone 6 is an excellent and almost timeless device that you could hold on to for years. The first and most common issue to come up is the deteriorating battery.
Batteries aren’t designed to last forever, and in fact, many of them won’t survive more than 2 years. This means it’s often the first thing you need to upgrade in your iPhone 6 (if you haven’t already cracked your screen).
The problem most people face when they decide to buy a new battery is whether to stick with an original and often inferior OEM battery (from Apple) or use a third-party battery.
There are pros and cons to this, and there are lots of terrible quality replacement batteries on the market – but that’s where I come in.
I’ve taken the time to go through all the poor-quality batteries and have pulled together this list of what I think are the best iPhone 6 replacement batteries out there.
I didn’t just choose the most expensive ones. Instead, I looked for balance. The balance between cost, real-world performance, build quality, safety, and longevity.
You’ll find excellent alternatives that can also be used as a spare battery if you don’t want to use them as your daily use battery.
Before the end of the guide, we’ll take a quick look at some of the most frequently asked questions to hopefully answer some of yours too.
By the end of this guide, you’ll have a very good idea of what it takes to make a really good quality replacement battery, and how to get your hands on one.
You’ll be well-informed and ready to choose a replacement that will take your device to the next level and help you get more out of it – more than ever before.
With all that said, let’s get into the guide!

With a pretty comprehensive installation and battery changing kit, you won’t have any trouble actually removing and installing the batteries.

You can expect several hours of ordinary and non-intensive use from the new battery.
This model is compatible with the iPhone 6s and not the other models. I’ve included it at the top of the list for this reason.
It’s not an iPhone 6 original battery, but if you’re using the 6s then this is an exceptional offer.
It’s safer than you’d expect and has a built-in IC chip to prevent against charging overheating and related damage.
The battery itself isn’t too heavy and you won’t even notice the extra weight in your hands.

With slightly less capacity than the above replacement battery, this one is fully compatible with the iPhone 6.
You’ll get far enhanced battery life compared to what you’d get from the OEM battery.
The toolset is fantastic. It had everything I needed to pop open the phone and replace the battery. I thought they felt pretty durable too.
Some of the plastic tools felt a little brittle, but I can’t say for sure how they’ll hold up over time. The rest of the tools are excellent quality and can open your phone without damaging it in any way.
Each battery is strictly tested before being shipped out, so you’re far less likely to receive a faulty unit.
There’s also a video link to an instructional video that shows you exactly how to replace the battery on your iPhone 6. It’s clear and easy to follow along with.
You also get a couple of wet and dry wipes to make the installation process even easier. Overall, I think it’s the best replacement battery for iPhone 6 if you want to DIY install.

The replacement kit is much better than the previous repair kit. It has everything you need with the exception of a couple of wet and dry wipes.
There’s a link to a guide video to help you through the installation period. I found it easy to follow and do myself, but I have experienced it (it might be a little challenging for the first-timer).
You’re getting a 27% boost in battery life and performance over the original battery. This is excellent considering that this is one of the lightest batteries at this capacity that I’ve ever had in one of my devices.
You’ll notice how light your iPhone feels right away. The issue is that it does have some heating problems.
From what I saw, they aren’t bad at all, though you may need to take a break once it starts getting hot. It might also be a good idea to only charge via the original charger.
In terms of functionality and design, it’s among the top choices for best iPhone 6 replacement battery.
I also thought that it held its charge better than expected when the device is left idle. This is quite rare for these ultra-light batteries.
It’s safe enough to make it onto this list, but it’s not its strongest feature. I’d say that the 700+ charge cycles and the lightweight are the best aspects of this battery.

If you thought that the last battery was light, this one knocks it off the podium. At under an ounce, it’s one of the lightest batteries you’ll find on the market.
I’m amazed at how such a lightweight is achieved while still keeping the capacity and safety ratings on par with the best iPhone 6 battery replacements.
It also faces minor heating, but it’s nothing serious. It’ll only start to heat up after playing games or large downloads. This can be easily fixed by leaving the device in a cool spot for just a couple of minutes.
Other than this, it’s one of the most tempting offers in this iPhone 6 battery review.
The main reason that I liked the installation kit was that the tools seem to have been carefully designed with the beginner in mind. They’re really easy to use and have ergonomic grips. Even as a beginner, you shouldn’t have any issues removing and replacing the battery.
Overall, it’s a top pick for best iPhone 6 replacement battery if you love light and classy designs and an excellent self-installation kit.

The special feature of this deal is that it comes with a glass screen protector while still keeping the price at the same level as the others on this list – exceptional value for money!
With 400mAh on top of your original battery, this has more than enough juice to get you through the day without needing to sneak in a quick recharge.
It doesn’t have the longest life span and the safety ratings are decent.
This isn’t to say that it’s not a solid choice – it specializes in offering you serious value for money, so if that’s what you’re after, then this is a fantastic option.

Here’s an alternative if you want something less feature focus, and more quality-focused than the battery above.
You’re still getting a screen protector and a great quality repair kit – but with a low-capacity battery.
It has more effective charge cycles and is a little more expensive.
This is the price of the added safety ratings and additional testing that the batteries go through before being shipped out.
This all means that you’re getting the quality of an iPhone 6 original battery, with additional capacity and more effective charge cycles.
