The case offers Fast Charging and my phone took advantage of it often and charged up my phone very quickly (see my picture).

I am a big guy and I like the slightly thicker phone with this battery in it.

But what good is a phone without power to use it?With nearly triple the capacity of the standard Galaxy S4 battery, this ZeroLemon battery provides that solution.

But I had my phone in my pocket and cracked the corner of the glass.

As it is now, you'd have to remove the phone from the case, charge whatever device via the phones usb c port, then put the phone back in the case to top it off

Hopefully in the future you can have one the size of the original battery to combine the sleek phone with all the necessary power needed.

Brilliant my phone is usually flat after 9 hours but now happy days last for three days all I can say is brilliant

To my relief my phone survived the fall.

Not only does the S9+ already have a decent battery life, this just makes it so that your phone will indefinitely survive the day, and some of the next day as well

Dont wrry about having a huge heavy phone; its not really bad at all

The battery works, but the battery does not fit the into the phone well

Also the battery when you put it into the phone covers the speaker so your phone is much quieter that was one of the worst things about the battery.

The case fits well and looks pretty well, seems to protect the phone okay too

An added bonus, the phone is heavy enough to be a weapon now.

I dropped my phone from 7ft onto ceramic tile and the case protected it perfectly!

I've gone up to 2 weeks without charging on my s4I needed it because I take a lot of photos and videos which kills the phone really quickly with this battery I've been able to use it all day everyday for at least 4 days ...not bad

An awesome battery for an awesome phone

The phone doesn't feel hot on charging or while in use

I dropped my phone once and the screen cracked so

When the external battery was sealed in a dry bag with the phone when kayaking, the phone would get hot and quit charging, which turns off the external battery and then the phone dies.

The phone get hot when you charge it.

Still protects phone during minor falls.

I am a computer professional and I need my smart phone

If your phone is compatible with this battery and you do not mind lugging around a little extra weight, by this thing

Phone would simply overheat while in pocket to the point it felt like the phone would simply go up in flames

doesn't make me feel bad that I placed a really expensive phone inside a really cheap and crappy case

The phone gets hot.

This sounds silly, but my last phone made me neurotic about charging.

In a given day I usually have 4 hours of screen on time and then my phone was dead

I have also dropped the phone on hardwood flooring with the battery in it and the case DID protect the phone

The case that protects the battery and phone just feels right

So locking and unlocking the phone feels funny to say the least.

I was walking up an open spiral staircase and when I was about 15 feet off the ground, the phone slipped out of my hand and tumbled to the ground down below.

My phone dies in 2 days or less

I am willing to make to keep this great phone up & running

I loved how this case protected my phone

But do I miss charging my phone in the middle of the day or worrying that it might die on me at the worst possible time

Maybe it's just a bad phone design putting the speaker on the back :-(.

I had set my phone precariously on a 4ft high counter and the phone took a tumble onto hardwood floor, landing on a corner-- phone took the fall like a champ, with no damage

Can keep my phone alive all day no problem

Get a high quality charging cable like anker and the phone will fast charge through the case no problem.

It only charges the phone from 10% up to 50% before it dies, with a single flashing light

phone last much longer love these

Phone is a little bulky but fits in my pocket just fine, the case is perfect

The phone landed face down so without the raised edge around the screen the case provides I have a feeling my phone would not have survived the fall.

Phone would simply overheat while in pocket to the point it felt like the phone would simply go up in flames

It just made my phone a heavier, hotter paperweight after a few hours

The only thing is the case does not fit the phone very well, but it does have a raised edge which protects the screen somewhat

When the external battery was sealed in a dry bag with the phone when kayaking, the phone would get hot and quit charging, which turns off the external battery and then the phone dies.

Yes, the phone is larger as a result, but I like that because the phone is too thin to hold out of the box

.. there's a indent on the case for the camera so now you could lay your phone flat without worrying about scratching the lens.

While having a thin and light phone is great, it is a PITA to go look around for a charger

but at the cost of almost breaking the phone.

The case protects the battery but more importantly the phone

Why shouldn't I just ditch this car battery and have my slim sexy phone back

Works great, the phone is much more useful than before and no longer need to carry replacement batteries for middle of the day changes.

My wife dropped her phone and cracked the glass.

I dropped my phone one time with this case on hit on the side and broke the screen and lcd

They are claiming it can protect your phone but after dropping my phone in just a short fall my new phone screen shattered.

Now im a power user so most people wont use their phone like me.

The case is sleek, fits comfortably and securely in the hand, all slots, connectors, whatever, are lined up perfectly, and the phone looks great.

If it wont protect your phone!!!

I love not charging my phone every day

the charge is magnificent, my phone is always ready to do whatever I need it to do without the annoying, uh oh my battery is dead gotta wait for it to charge, love my zero lemon, only 4 stars because I haven't had it long enough for it to have pooped out on me yet, like everything seems to do

The included case will do nothing to protect the phone.

Phone looks little fat from side but from front nothing different

My phone was hot like its gonna explode.

Protects your phone like a normal case.5

Not having to worry about charging it if I'm using my phone is great.

protects the back of the phone pretty well, not so much on the screen side.

I work in a very harsh environment, where I have broke a few phones, but the car they make with this is pretty durable, and I dropped the phone once with no problems

I'm a chronic phone dropper, so that was important to me

Makes phone very heavy and bulky

Zero lemon saved my phone

The new backing they give you feels good and sturdy and has protected my phone from a few short drops

But does not protect the phone

.... could hardly hear phone loud speaker with case on

Now the battery overheats my phone

You just can't have a sleek thin phone and a 7500 mAH battery at the same time.

What good is a phone with a big battery if the phone doesn't work with anything

It caused my antenna 2 be blocked 2 the point that my phone was useless

This is not true even that the case of ZeroLemon doesn't protect the phone

my S4 is the best phone I've ever seen!

My phone overheated as soon as I used it

On average (of three tests), this battery:Slowed this phone's download speed by 68%;Slowed this phone's UPload speed by a whopping 84%;And made ping response time 92% slower

Of course I have a phone charger in the car, but if the phone is completely dead it will take at least 5-10 minutes before you can power it on.

It did not break my phone or screen

With the case and the larger battery, (looks like three normal batteries were were wrapped together with the company's business card and then called a label,) your phone will feel like a brick

The only down side is that if you like a light phone thats easy to put in jeans is kinda tough

The bad thing: Such strong batteries for smart phones are not available in Germany

Let's face it--the biggest drawback of the modern cell phone is a paltry battery life.

So when your phone is dead and the Case is dead it takes forever to charge both of them up

I could maybe force the battery in flat, but risk damaging my phone

Plus it comes with an accommodating scratch proof phone cover

The custom backing also protects the phone from damage.

I finally upgraded to a smart phone and was shocked at how quickly the battery is drained (even when no applications are running).

The thick rubberized back is a bit crude compared to the Samsung original but is serviceable and protects the phone nicely.

And even of it becomes a bit heavier it is even better because now it really feels like holding phone

Case is great, makes the phone feel solid, and it feels good in your hand.

It also protects the phone kinda good.

The battery and case fit the phone like a glove and provides tremendous battery life.

As for cosmetics, I think the phone looks nicer like this, the TPU case is nice looking and grippy.

-- it adds a bit of bulk but truly enhances the phone's performance

Since my introduction to the product, I share it with others who need extra assurance that the phone is available when when the demand level is high.

However, the phone, being fatter, now doesn't fit on my dollar-store dock

Love this battery it never dies I do super heavy use youtube and internet and games all day with GPS and after 20hrs still 30-40% left at the end of the day you want to use your smart phone all day for any thing you want get this

That's OK.Roughly when it was being delivered, I, several miles away, dropped my phone onto concrete, from about a meter, and it smashed

What good is a phone with a big battery if the phone doesn't work with anything

The phone is obvious a bit bulky and a bit heavy

although this had good reviews and that is why I bought this (even though it made my slim Samsung phone look like a ton of bricks)

It also protects the phone kinda good.

Long story short, my phone has no problems with the Anker
