**********Work in progress************

I just received the ZeroLemon 9,000 mAh Extended Battery and Case for the LG V10 today.
I am going to leave a review here and update this as I use it for the first few charges.

Before I start, ZeroLemon did provide me with this extended battery and case for review purposes.
Like all of my reviews, this does not affect my opinions of the product and this will be my honest opinions and thoughts.

I have attached quite a few pictures to this post, however if you would like a different picture, just let me know.

Let me start this by saying, this case big.
You know this already though if you wanted this huge of a battery in your phone.
This case is not quite double the thickness of the phone.
The phone at its thickest point without the case (The camera hump) is 0.417 inch.
The phone with the case on is 0.703 inch.
The case will add 0.286 inch to your phone.
I find this is still pocketable, about the max that I would want to carry in my pocket but I can do it and it does not bother me.

The flaws that I found in the LG G4 case and battery have been addressed this time on the LG V10 case.
The ports at the bottom all have a small lip to prevent dust intrusion.
The sides of this new case are thinner and do not add any bulk to the top, bottom, or sides of the phone.
They have added Fast Charge capabilities to the battery this time around.
With Fast Charge comes huge decrease in charging times on this battery vs the one from the G4.
This is a welcome addition considering the 6 hour charge times of the past.

This case is much like previous ZeroLemon cases in overall design.
The looks are the same while the case seems to be a little softer material this time.
There is quite a bit of internal structure in the top portion of the case that is extended above the buttons to make this case much more solid than previous cases were.
The sides of this case are flush with the screen while the top and bottom both stick up slightly to prevent your screen from ever touching anything should you lay your phone down screen first.
This slight change from previous cases makes a huge difference in the overall feel of the case in a good way.
The ports on this case all line up perfectly, including the opening on the back for the camera and volume/power buttons.
The headphone opening is large enough for me to use all of the headphones that I have.
The USB port is also large enough for me to use all the USB cables I have.
The overall fit of the case is excellent, I for one am glad that they did not release this case until it was perfect.

DAY 1
Battery life so far has been excellent.
First day I have 3 hours screen time and approximately 11 hours of use.
I did have this connected to a moto 360 smartwatch via bluetooth as well as a pair of bluetooth headphones.
I had about 4 hours of music streaming on and off throughout the day.
I have the screen set to 100% and 2 emails, one gmail and one exchange, both set to push.
I have 55 minutes of voice calls today.
I started the day with the battery at 92%.
The battery is now sitting at 68%.
On an day like today my battery would usually have been at about 15% and I would have had to charge when I got home or swap a battery out.
I do not think it is possible to kill this battery in one day.
If I had had the screen set to auto brightness I would easily get double the screen on time.
DAY 2
Battery life is still excellent, better than the first day.
Ended the day wit 72% remaining.
75 minutes of phone calls.
3.2 hours screen on time.

DAY 3
Battery life is getting better still
Ended today with 75% remaining.
78 minutes of phone calls.
3.2 hours of screen on time.

I will hold off on updates for a few days.
So far usage is steadily improving over what I had already considered excellent.
I will update this again in a week or two with detailed stats.

I will update this section as I use the phone over the next few days and charge cycles.
So far the battery arrived with 56% charge.
I installed the battery in my phone and put the case on it and plugged it in to charge in a Quick Charge 2.0 charger.
It charged to 100% in approximately 45 minutes.
This is the first charge and I let it charge for an additional 12 hours as stated in the instructions.
I do not think it actually takes that long, however it is what is recommended so I will do it.
ZeroLemon recommends to allow 5 to 6 full charge cycles to achieve optimal performance.
I will come back and update this review after 6 full charge cycles with battery stats then.

**So far I have one day usage reported, I will continue to update this for a while or as long as people ask for updates.**

Can the sd card be removed without removing the battery?

I'm getting pretty excited here! As soon as I come up with some creative bookkeeping I'm going to order one of these! (hopefully they're back in stock soon)

Yes the SD card can be removed without removing the battery, you would still need to shut off the phone first I would assume.

How's button access? Is it awkward to use? How about the fingerprint sensor?

Thanks for the in-depth review and pictures.
You are welcome, I will update it tomorrow after work.

Button access is better than I expected.
The sides of the opening are slanted so your finger is sort of pushed right where it needs to go.
For the fingerprint sensor... I have the T-Mobile version and do not have the update that fixes the fingerprint sensor.
So you still have to be touching the metal edges for it to work right on mine.
However the if I flex the side of the case a little I can get my finger on the metal edge of the phone and it works perfect.
I would assume once I update my phone to fix the sensor there would be no issues at all.
If you have a version that does have the update for the fingerprint sensor it will work perfect for you.

Hi, thank you for review, can you please shoot a photo side by side (I know it needs work but appreciate) with and without the case to see the real thickness of the device with the battery.

Thank you for the effort.

What about photos? Does the case interfere with the autofocus, or does it cause the flash to interfere with the picture?
I did not notice any issues with it, I will check again today after work.

I will try, but it will be difficult to get both items to scale. I do have a caliper that I can actually measure both with and give the measurements.

Updated the original post with measurements via caliper.

The phone at its thickest point without the case (The camera hump) is 0.417 inch.
The phone with the case on is 0.703 inch.
The case will add 0.286 inch to your phone.

I have the AT&T and it has been updated. The fingerprint scanner seems to work even better. I get a lot faster response from it.

Got mine yesterday. Charged 12 hours overnight and put it in this morning at 07:40. It's now 09:02 so coming up on 1.5 hours and I am down to 73%. I hope the % is way off if not I got a lemon. Probably 1 hour screen on time

Is this their regular case or a ZeroShock Case?
How do feel about the texture of the outter cover? Does it feel slippery? Or real "grippy"

I am getting very similar results. I posted about it in the other thread but I'm thinking maybe we need to calibrate the battery? I just don't know how. But yea... I'm getting pretty much normal battery life.

Well, now it's 13:25 and I am down to 15% left. With the normal battery I would be around 40 at this time.. :(

I'm curious if you have the standalone LG battery charger, does the ZL battery fit or would the cover flap need to be removed?
If you do and it does fit I'd appreciate a pic!

I don't see myself needing two ZL batteries, but it would be nice to know if it's still a good charging option without having to modify.
Based on your photos it looks like it could possibly just fit or be a slight squeeze.
Thanks!

Yep. It fits without any modifications. Just won't close, obviously. Did it on my initial charge so I didn't have to stay tethered to the wall for 12 hours.
