    I use my Samsung Galaxy Note 9 for work, play, and family. I'm told that I am a power user, especially since I'm lucky if I can get more than 10-14 hours out of the battery before I have to charge it. Even With my Note 8, I was lucky to get 8-10 hours. While the Note 9 has a 4,000 mAh battery (the main reason I got this phone), I still need to carry an external battery pack and USB cable if I am out and about and taking pictures and video. I wanted another option and found this battery case. Having the battery built into the case so I don't have to carry an extra battery pack and USB cable makes this worth it. The blue color looks great, and the case fits my phone like a glove. The texture on the back is just smooth enough to feel nice without making me feel like the phone will slip out of my hand. The buttons still work as designed (in some cases interfere with this) and the case still works excellent when removing or inserting the S-Pen. I especially like that with the case on, if I plug the case it, the case and phone are both charging.

    Battery
    Now for the battery part. I noticed when I turn on the battery pack, my phone says fast charging, but then after a few minutes says cable charging, which makes sense as this is only a 1.5A charging output spec. To test the case, I unplugged my phone at 6 am on Sep 8th and used it as normal all day without ever charging it. By 8 pm, my phone was down to 25%. Most of the time my phone would be dead at this point, but I guess that I did not use it as much since I was off work and getting fewer emails. I powered on the case (which I fully charged beforehand) and set my phone down. I did not touch my phone at all while it was charging from the case. Not wanting to leave it charging overnight as the battery was getting rather warm, I turned off the battery case at 9:30 pm, my phone was at 55%, but I also noticed the battery pack was already down to 2 LED lights (50%?!?!); based on that, I should have only used about 1,500-2,000 mAh of juice. Even if the battery case was down to 50% (2,500 mAh), that should be enough to fully charge my phone when I get up, so I powered the phone off.

    When I got up at 4 am, my phone was still at 55% and the battery pack at 50%, so I turned the battery pack back on. Unfortunately, the battery pack only charged my phone to 82% before the battery pack died. While I do not have the ability to test the mAh capacity, based on the math above, it does not seem to be a 5,000 mAh battery as that should have been enough juice to fully charge my phone and have a tiny bit left over; not run out at 82%. I have read online that you need to duty-cycle the battery in the case; let it die fully and then fully charge it so it can calibrate to a full charge. So I'm going to do this and see what happens.

    Things to be aware of:
    • The battery may not be a true 5,000 mAh, but it's still worth the price and convenience.
    • If you have small hands, the fingerprint scanner will be hard to use.
    • There is no data pass-through, but that is advertised.
    • The phone may say it's fast charging, but I doubt it.
    • This thing is thick, like 3/4" thick, but not too thick.
    Pros:
    • Great fit
    • Does not add that much weight
    • Build quality feels solid
    • Color is beautiful
    • Does not interfere with the holes or S-Pen
    • Charges quickly
    • Charges phone and case at the same time
    • Buttons work great, better than others cases I've used
    • Raised edge and top and bottom, so the screen does not touch table when placed face down
    Cons:
    • Does not seem to be a true 5,000 mAh battery
    • Thickness (about 3/4" thick), not really a con as this should be expected
    • No data pass-through
    • May be difficult to use the fingerprint scanner for smaller hands
    Conclusion: I like this, and it is very worth it. I highly recommended this for the Samsung Galaxy Note 9.

    Update on the charge level: After fully charging the case (after letting it fully die), I am pleased to report that this will fully charge a dead Note 9, so it is at least 4,000 mAh.
    I left my Note 9 off the charger all day yesterday and last night; at 7:01 am, I got the "Battery at 15%" warning, so I turned on Power Saving Mode with background data turned off, and the screen to only 25% brightness. I shut off GPS, Wifi, and Bluetooth and then put the phone into the case and turned it on. Around 9:45am-ish, my phone buzzed and was at 100% with 1 LED left on the case. I estimate this is about 3,000-3,300 mAh worth of juice. By noon, I was back down to 75%, turned on the case and it too me back to 95% before the case died. Based on that, this is close to a 5,000 mAh case if my math is correct. The full duty-cycle was needed and made a large difference in the charge available for my phone.
