Here’s Our Guide to the 7 Best Galaxy S5 Replacement Batteries

1 PowerBear Samsung Galaxy S5 Extended Battery

Check Price On Amazon!

The case design is superior to almost all of its competitors. The hard case is unbelievably sturdy and durable. This is achieved without adding a lot of extra weight to the setup.

You’ll find the device is still super-easy and ergonomic to hold. It feels safe in your hands and will definitely protect the battery from damage.

You’re getting a whopping 7800mAh (an extra 275%) battery capacity. This is more than enough to get you through a day or two of consistent use.

The battery is slightly more compact than competitors like Angker and this goes a long way to improve usability and comfort with the device.

You won’t experience excessive heating or the risk of damage. There’s intelligent fail-proof in-built IC that prevents overheating and leakage.

It’s possibly the best replacement battery for Samsung Galaxy S5 if you want a good balance between capacity, design, and safety. It’s worth taking a good look at if you want serious performance.

2 Official Samsung Galaxy S5 Replacement Battery

Check Price On Amazon!

This is an official Samsung produced replacement battery for Samsung Galaxy S5. You can be assured of the quality that it promises.

There are pros and cons to buying official accessories for your devices. They have to meet certain quality standards and you can generally rely on their quality as it’s linked to the image of the company.

I find that official accessories often lack in creativity. I can only speculate the reasons for this so I won’t go into this.

Many third party manufacturers get very creative and can deliver good quality at the same time. This battery is set at the same price that others with 3x the capacity cost.

This is the trade-off you need to be willing to make if you want the peace of mind from the improved safety of official batteries.

You’ll still get decent life out of this battery if you’re looking to replace your internal battery, but it’s nothing special.

It’s well suited to media consumption and browsing uses, but it’ll struggle with gaming and heavy use. It’s most likely the best Samsung Galaxy S5 battery replacement if you want high quality and increased safety.

3 CyberTech Galaxy S5 Battery Combo

Check Price On Amazon!

This set packs in quite a few features for a very affordable price. This is likely the best extended battery for Galaxy S5 if you don’t like the bulky case batteries.

There are two ultra-slim and light batteries that you can easily install in just a couple of seconds. They’re portable and don’t take up much space at all.

The set comes with a separate charger so you don’t need to put the battery in your phone to charge it. Charging times are a little faster than most batteries at this price thanks to the higher voltage input.

You get the functionality of a larger battery pack or battery case without needing to have all that extra weight and bulk on your device.

The caveat is that you’ll need to find a way to carry the extra battery and possibly the charging block around with you. This isn’t an issue for all, but it’s something to think about.

I also found them to have longer standby times. Leaving the battery out for a couple of days didn’t diminish the battery life as I expected it to. I found this very surprising for a battery set at this price.

Overall, this is a top pick for best replacement battery for Galaxy S5 smartphones – it’s great value for money!

6 SHENMZ Replacement Battery

This is probably the best replacement battery for Samsung Galaxy S5 that I’ve ever used. It far outlasts its competitors at this price range and even puts original Samsung batteries in their place.

You’ll get up to 16 hours of life with normal daily usage, but this figure will vary depending on how intensely you use your phone.

The capacity is higher than what you’d usually get from most batteries at this price and size range. You’ll be more than happy with the quality of the performance – there isn’t much bad to be said about this battery.

If you’re all about performance and want a huge battery to support you – then this is possibly the best extended battery for Galaxy S5 you’ll find.

It’s a massive 7800mAh, which is more than even flagship devices offer these days. You’ll get a huge boost to your screen on time and the ability to take your phone almost anywhere and not have to worry about charging.

Safety becomes very important with these large batteries. The in-built IC chip and the A+ rated battery cells work together to give you a very stable and reliable battery to power your S5.

It’s bulky but as bulky as you’d think. You’ll be able to carry this in your device when using the protective case and not feel like you’re lugging around a brick.

It does take a while to charge, but it’s reasonable for a battery of this size. Charging for an hour or two will give you a day’s worth of usage.

These extended batteries are excellently suited to the power user. Whether you’re into games or hours of media consumption, you’ll find that this battery is more than capable enough to keep up with you.

Frequently Asked Questions (FAQ)

Q: What are battery charge cycles?

A: Charge cycles refer to the number of times that a battery can lose 100% charge. This technology is changing now as new types of batteries are being made and the tech is being improved on. For most modern batteries, if you charge the phone up to 100% – then drain it until it’s down to 40% – then you have completed 0.6 cycles. If you charge that same battery up again and then drain it until it reaches 60% (using an additional 40%), then you will have used 0.4 cycles. Adding the two partial cycles together will give you one full charge cycle. Most ion-lithium replacement batteries on this list have between 400-700 effective charge cycles until they need to be replaced.

Q: Is it okay to leave a battery on charge even after it reaches full (100%)?

A: This used to pose a huge threat to battery safety in the past, but not anymore. Now, modern batteries like the ones in this review come with an in-built chip that prevents overheating and overcharging. It has control over the input and output of the battery and will make adjustments before things begin to get dangerous. You won’t need to concern yourself with constantly monitoring these aspects.

Q: What size battery is best for a Galaxy S5?

A: The answer to this question will depend on how you use your phone and you probably won’t be doing heavy gaming or video editing on an S5. I find that a 2800 – 3300mAh battery is enough to get me through a day of moderate usage. I can watch videos, movies and TV shows for hours and I’ve never experienced an unexpectedly drained battery. The larger 7800mAh batteries can get you through several days of light to moderate intensity usage. Don’t take these figures like the law; just remember that they’ll vary hugely depending on the type of usage and work you put the battery through.

Q: Why does my Galaxy S5 get so hot?

A: Batteries and phones generally heat up when they’re taken to their upper limits. Often you’ll find that your S5 is hottest around the section where the battery is. This is normal and most batteries will limit their performance if they start getting too hot. Most will simply shut off and switch off the phone before reaching critical levels of heat. This heat is being generated by quickly charging and depleting the batteries. This is why tasks like gaming of resource-intense activities create more heat. The best thing to do is to cool your device down by sitting next to a fan, or putting the phone in the fridge or freezer for a couple of minutes. Taking a break and giving it a rest will be the best medicine.

Our Final Thoughts

This isn’t a terribly important decision, so don’t get too caught up in trying to get the perfect battery.

All the options we’ve looked at pretty similar, with some models offering special performance. This performance often comes at the cost of being heavier and bulkier, so it’s up to you to decide what’s most important.

If you’re a power user, traveler, or simply want a battery that can last you at least 2 days – then go for the batteries with a larger capacity. The 7800mAh batteries are probably the best option for you. If you need something light and easy to carry around (maybe as a spare battery), then getting one of the lower capacity 2800-3300mAh batteries will work best for you.

There are some options that are dirt cheap if you’re just looking for something quick and easy to install and use right away.

These batteries all have a reasonable charge cycle count and will give you a good life before needing to be replaced.

Go ahead and choose the one you want and order it. Your new best replacement battery for Galaxy S5 will help you get more out of your device, and ultimately, more out of life!
