Best Extended Battery for Samsung Galaxy S4 【Oct. 2018】

Home » Batteries »

I contend that 90% of battery manufacturers are scammers.

s4-2

6 out of 10 brands were gone while I was writing this review. This is 60%!

I wrote reviews for many products. And I talked about the battery for Samsung S5 earlier. I got a real investigation, many people were interviewed.

But now I realize that we need to delve more deeply into the topic.

I did research.
  1. They lie about the guarantee and don't support in any way after purchase.
  2. They lie about battery capacity. When checking it turns out the other. Often it is less than your old 2-year battery.
  3. They lie about the safety certificates and are selling really dangerous products.
  4. They lie about the brand. They sell you a fake or used battery in a new bright wrapper.
  5. You can not rely on reviews. Scammers know the feedback system and juggle it to their advantage.

While this review was being written, I saw the product disappear and immediately appear under a different brand, and after a couple of days it has hundreds of rave reviews. Or all the negative reviews are cleaned in some way in one day.

I don't know how they do it. I'm serious.

And I cann't refer to any page, because they are removed with the space velocity.

But a fact is a fact. The battery can easily destroy your phone or harm your health.

In this article I have tried to give you complete picture in this niche. Keep reading if you want a safe battery that lasts a long time.

Let's start talk about the finalists.

How to choose a replacement battery for Galaxy S4: the most important factors to consider

Despite its age, Samsung Galaxy S4 is a great smartphone. It was released over five years ago, but you still can perform all everyday tasks with it. Thanks to the powerful CPU, Full-HD display and high-quality cameras, this device can compete with the most of modern counterparts. The only aspect of Galaxy S4 that may seriously let you down is its battery life.

It loses its quality over time, so you will have to replace it at some point. In this article, I will tell you about the most important aspects of spare batteries for Samsung Galaxy S4 smartphones.

The capacity of a Galaxy S4 battery: How Chinese brands cheat you

The very first rule that you have to remember is that you should not believe cheap and generic brands from Amazon. You can find hundreds of Galaxy S4 replacement batteries online, but every single one of them will offer much less capacity than advertised. Of course, all Amazon sellers claim that their products are licensed and checked for standards appliance, but 99% of them are lying.

Just think for yourself: do you really believe that somebody thoroughly tests and certifies every 10-dollar battery out of thousands? No way! It is really hard to check whether an off-brand replacement battery has any certificates, so you have to count on reviews from other buyers to find out its true capacity. However, this method is also not perfect, and here is why.

Most of Amazon users leave reviews soon after the purchase and never edit them (especially if the product is cheap). Other customers will not give you 100%-accurate information because counterfeit replacement batteries for Samsung start deteriorate after a couple of months of usage. Therefore, the battery capacity indicated in the product’s details should not be your main choice criteria.

How to measure the true battery capacity with AccuBattery

The most accurate way to measure the Galaxy S4 battery capacity is through the AccuBattery app. It will also help you to slightly prolong the battery life. You can download it for free from Google Play.

Drain the battery until the smartphone turns off, and then fully charge it and open the application. It will automatically estimate your battery health in the “Charging” tab. Usually, the true capacity of off-brand Samsung batteries is about 20-30% lower than the advertised value.

Does the replacement battery support NFC?

Original Samsung Galaxy S4 battery allows you to use NFC features of the device. Thanks to it, you can share files from your smartphone and use the Google Wallet service to perform contactless payments.

Be careful when buying a replacement battery if you often use these features, since not all of them support NFC.

The cheapest replacement batteries for Galaxy S4 come without the built-in NFC chip (especially the ones with the extended capacity). Read the product’s description to check whether you can use it with NFC.

If the seller does not mention NFC at all, look for another option. Of course, you can buy a thick and cheap replacement if you only care about battery life, but I do not think that is a great idea. There are many off-brands products with NFC support and they are only slightly more expensive. What if you will need to use NFC features? Do not be greedy and buy a decent product!

Protection chips: useless or useful?

Some people think that replacement batteries are simple and harmless things that do not require any protection. Speaking from my personal experience, this is not true.

A few years ago I bought a cheap replacement battery for my old smartphone. At first, I did not have any problems and was absolutely satisfied with the purchase. However, one day I noticed that my smartphone is acting weirdly: it started to randomly turn off and on. I took off the back cover and found out that the battery was leaking!

Turns out, it did not have any protection chips. The battery overheated, which caused short-circuiting. My 400-dollar smartphone was permanently damaged by a 10-dollar spare part! After this incident, I always check batteries for protection chips because I do not want to turn my Galaxy S4 into a brick.

Thanks to protection chips, the battery evenly and firmly releases energy to power your smartphone. Otherwise, the spare part may overheat and catch on fire or even explode. Yes, you have read it right: your device can literally blow up in your hands!

If you do not want to risk your health and money, make sure that the replacement battery for Samsung Galaxy S4 comes with built-in protection from overheating, overcharging and short-circuiting.

Samsung Galaxy S4 batteries warranty: are they important?

Shortly speaking, no. Not a single off-brand battery comes with an honest warranty protection. You should not trust Chinese brands that promise 12-month or even 24-month warranty periods.

Most of the time you will not even get an answer from the seller, let alone actually receive a replacement.

Nevertheless, there are reliable Chinese manufacturers with a good reputation that will indeed replace a defective product. However, even they do not offer long-time warranties.

You will easily get a replacement the first time, but if it also turns out to be defective, the seller will not replace it for the second time.

Considering the above, do not rely much on warranties. After all, off-brand spare parts are rather cheap and it is easier to simply buy a new battery instead of messing around with no-name manufacturers.

Other criteria

Before I managed to find a reliable replacement battery for my Samsung Galaxy S4, I tried numerous options from various manufacturers. Through trial and error, I distinguished the most important characteristics of smartphone batteries.

I recommend you to check them up here (тут ссылка на статью или параграф) before making a purchase. Besides that, batteries have many less significant characteristics.

They do not matter much, but you can rely on them in order to find the very best product or make a decision between two similar options. Let me tell you about them!

The energy efficiency of a battery

Most people looking for a new smartphone battery know what the battery capacity is. However, not everyone is aware of its energy efficiency.

This factor is usually ignored by off-brand manufacturers so you will not find anything about it in the product’s description. There is a term called “Coulombic efficiency” (CE) and it is used to describe the charge efficiency by which electrons are transferred within the battery.

Lithium-ion batteries have one of the best CE ratings among rechargeable batteries. Their efficiency exceeds 99%, which is a great result.

However, such a good CE ratio is only possible if the battery is charged at a certain and stable current and at cool temperatures. Fast-charging technology lowers this parameter because of losses caused by heat.

Energy efficiency for smartphone batteries is hard to calculate on paper since you cannot charge them in the ideal conditions. The most accurate way to do it is to use an AccuBattery app, which is available on Google Play for free.

Before buying a battery, ask other buyers to test it with that app to see the efficiency rate. A new OEM Galaxy S4 battery is 85-90% efficient, but its off-brand counterparts are usually less efficient.

The actual capacity of a battery

In most cases, the actual battery capacity differs from the one stated by manufacturers. Unfortunately, the only way to check the true specs is to use a battery monitor app. Use the above-mentioned AccuBattery or any other app in order to do that.

It can also be helpful if you want to check the condition of your old battery. Even genuine batteries for Galaxy S4 from Samsung lose their quality over time, so the true capacity may be significantly less than the designed one.

The charging speed

Another factor overlooked by many people is the charging speed. It may seem insignificant, and that is partly true. Most batteries of the same size usually take the same time to fully charge. However, the cheapest models from Chinese manufacturers are made from low-quality battery cells that do not support the fast charging technology.

This means that you will not be able to charge your device within 15 minutes at cafés or other public places. If you are an active smartphone user and you often use it on the go, this fact might be very problematic.

The battery size

Samsung Galaxy S4 has a removable back cover, which allows third-party manufacturers to produce replaceable covers. Many extended batteries on the market come with an alternative back case.

Some of them look nice, but the cheapest options are really ugly and bulky. Moreover, as soon as you change the original back cover to an off-brand counterpart, your smartphone is no longer waterproofed.

If you want to keep the original back cover after installing a new battery, make sure that it has the same size as the OEM battery.

№ 1. Galaxy S4 Battery from Acevan (2900 mAh) - Li-ion Replacement Battery

This is a cheap and popular replacement battery from Acevan, a Chinese replacement parts manufacturer. The product comes with a user manual and a micro-USB charger. If you need a new battery for your Galaxy S4 then it is a great option for you. It offers the same quality as the OEM Samsung battery, but has a much cheaper price.

The product is made from high-quality Grade A cells that provide an effective high-speed charge and guarantee at least 500 full recharge cycles. It offers a slightly higher capacity in comparison to the standard battery (2900 mAh versus 2600 mAh), so it will also improve the runtime for your Galaxy S4. At the same time, it perfectly fits the smartphone and can be used with the original back cover.

Just like other Acevan batteries, this one is manufactured and tested according to the latest quality control standards. It is 100% safe to use since it has CE and RoHS certificates, as well as safety microchip that prevents the battery from overheating, overcharging, and short-circuiting. On top of that, this product comes with three years of warranty.

Judging by customer reviews, this replacement battery offers the best value on the market. It indeed has a higher capacity than OEM and a great customer support combined with a three-year warranty makes it a completely secured purchase.

№ 2. PowerBear Galaxy S4 Battery (6000 mAh) - Extended Battery for the Samsung Galaxy S4

This is a great Samsung Galaxy S4 extended battery, which offers a capacity of 6000 mAh. It guaranteed to last 2.3X longer than the OEM battery. The product is made with the best cells on the market (Grade A+), so it should last over 500 repeated battery charge cycles. Moreover, it has both CE (Read more about CE marking) and RoHS certifications and 24-month warranty to make sure that you are 100% satisfied with the purchase.

The capacity of this battery is more than twice larger in comparison to the standard one, so it is way thicker. Unfortunately, you cannot use it with the original Galaxy S4 back cover. It comes with the replacement back cover and an extra protective case. As you might have guessed, they make the smartphone heavier and clumsy. Additionally, you will not be able to use NFC features since this thick battery blocks it. Look for another option if you use Google Wallet or transfer files via NFC.

PowerBear is a rather popular company so this product has many customer reviews. Buyers appreciate the design of the protective case and claim that the battery vastly increases the runtime of the smartphone.

It should last for two days of heavy usage without charging, which makes it a great choice for those who often use smartphones while traveling.

If you are looking for a nice extended battery and do not care about NFC features, we definitely recommend you consider buying this product.

Suitable for: L720 (Sprint), R970, M919 (T-Mobile), I9500, I9505 (LTE), I545 (Verizon), I9506 (LTE), I337 (AT&T).

№ 3. YISHDA Galaxy S4 Extended Battery (5700 mAh) - Extended Battery

You will be able to browse the web, watch videos, play games, and chat with friends without charging for the whole day or even longer.

This battery is manufactured in compliance with the highest quality standards. It uses Grade A+ battery cells with RoHS and CE certifications, so you can be sure that it will not take too much time to charge or lose quality over a couple of months of usage. It also has a built-in microchip, which prevents it from overcharging and over-circuiting. Giving the fact that the manufacturer offers 18 months of warranty, you have nothing to fear while buying this battery.

The product has the larger size in comparison to the standard Galaxy S4 battery, so you will need to use the non-original back cover. We liked it: it looks similar to the original and feels nice in hands. You can also use it with the protective cover, which is included in the package. It does a nice job of protecting the smartphone while not making it look ugly.

The majority of user reviews on this battery are positive. It holds the charge well and offers a great value. Its main drawback is that the battery is thick and blocks the smartphone’s NFC microchip. If you often use Google Wallet or other NFC features then you should look for another replacement. Otherwise, it is a great option for a reasonable price.

Suitable for: I337 (AT&T), I545 (Verizon), L720 (Sprint), R970, I9500, I9505 (LTE).

№ 5. Galaxy S4 Active Battery from MAXBEAR (3800 mAh) - Extended Slim Replacement Battery

An inexpensive and trustworthy battery replacement for Samsung Galaxy S4, which offers extended power but does not require an extra large back cover. It has a slim design: from the first sight, you will not see the difference with the OEM battery. The item can be used with the OEM back cover of your smartphone, which is truly great since some replacement batteries make it overly heavy.

At the same time, the product offers nearly 150% more power than the original battery. Therefore, you are not only getting a light and cheap replacement for your worn out Galaxy S4 battery, but also significantly increase the runtime of the smartphone. Do note that it is made from the best battery cells on the market (Grade A+ rated), CE and RoHS certified, and designed to last over 600 charge cycles.

The product is compatible with all the NFC features without any restrictions. Feel free to wirelessly share contacts and file using this technology, as well as perform contactless payments with Google Wallet. The battery comes with a 12-month warranty to guarantee customer satisfaction. The company claims that buyers will immediately get a replacement in case of any problems with this battery.

№ 6. Stalion Strength Battery for Samsung Galaxy S4 (5200 mAh) - Extended Battery for All Versions of S4

An extended battery that delivers twice as much power as the OEM battery. It will help active smartphone users forget about charging the device for the entire day. Enjoy all kinds of contents without thinking about electric sockets!

The product is manufactured with CE and RoHS certified Grade A cells. It has a built-in IC chip that prevents the device from overheating, short-circuiting, and overcharging. Rest assured that your Galaxy S4 would not be damaged! The product comes with a 24-month warranty. Therefore, you will not have any problems replacing this battery if it starts losing quality over time.

This extended battery from Stalion is noticeably thicker than the original one. You have to use with the replaceable back cover, which comes with the package. It is made from high quality plastic, which feels nice in hand and looks as good as the original. Additionally, you can put on the protective case that will make your Samsung Galaxy S4 way thicker, but protects it from breaking in a fall. The only thing we did not like about the back cover and the protective case is the Stalion’s logo printed on them: in our opinion, they would look better without it.

Another important advantage of this extended battery is that it is equipped with an NFC antenna, allowing you to use Google Wallet and other NFC features. If you do not mind having a third-party logo on your Samsung smartphone, then it is a good extended replacement for a good price.

Suitable for: I545 (Verizon), R970, I9500, I9506 (LTE), M919 (T-Mobile), I9505 (LTE), I337 (AT&T), L720 (Sprint).

This is another slim battery that can be used with the original Galaxy S4 back cover. It supports all NFC features of the smartphone and is completely protected from short-circuiting, overheating and overcharging. The package is simple and does not include anything but the battery itself. However, it is pretty cheap and you are not overpaying for useless stuff such as extra USB cables that are usually not as good as the original.

The company claims that this product offers 500 mAh more power than the OEM battery (3100 mAh vs 2600 mAh). In fact, it provides the same runtime according to the most customer reviews since the quality of battery cells is not the best. Moreover, there is no information regarding the certifications or overheating and overcharging protection. On the bright side, the manufacturer offers 12-month warranty so you should be able to get a replacement in case it starts malfunctioning.

The battery charges quickly and holds it as long as the original. However, some buyers started to have troubles with it after a few months of use. Therefore, you should consider it as a cheap short-term solution if you know you will be buying a new phone in a few months. Otherwise, we recommend you to look for a better replacement.

Suitable for: I545 (Verizon), L720 (Sprint), I9505 (LTE), I9506 (LTE), R970, I337 (AT&T), M919 (T-Mobile), I9500.

№ 10. Samsung Galaxy S4 Battery from Perfine (7500 mAh) - Extended Battery

A giant extended battery for Samsung Galaxy S4, made for active phone users. It provides nearly the triple amount the power in comparison to the standard battery. It is very convenient for long travel and outdoor activities.

Unlike many other extended batteries, it is not shipped with a protective case. All you get is the battery itself and the back cover. The case looks terrible: it is made from cheap black TPU, which smells pretty bad. However, the smell usually disappears after a couple of days.

The battery is made from Grade A+ rated cells with RoHS and CE certification. It has a built-in microchip that will protect your Galaxy S4 from overheating and overcharging. The item is designed to serve for more than 500 charge cycles.

According to customer reviews, the battery does not offer the best longevity. It may start to deteriorate after a couple of months of heavy use. Additionally, the warranty period is pretty short (only 180 days), so you would not even be able to get a replacement if it stops keeping a charge after six months of use. If you need a high capacity extended battery for a low price you may give it a try. However, keep in mind that it is not very reliable and may get swollen after a couple of months if you get unlucky.

Suitable for: I9500, I9505 (LTE), I9506 (LTE).

 
Pros
Protected from short-circuiting, overcharging, overheating, and overloading;
Compatible with NFC and Google Wallet;
Offers a lot of power for active smartphone users;
Made from Grade A+ battery cells.
Cons
Short warranty period (only 180 days);
The quality of the replaceable back cover is very low;
Quickly deteriorates over time.
