    • Never deal with another dead battery
Anyone who owns a Note 20 Ultra knows that the battery drains so quickly, and it's annoying. This case is a must-have for me. I started using this case and now I can't go anywhere without it. The price and features you get are unbeatable. Other battery cases are upwards of $50+ and have fewer features. If you still need a case, this is all you need. ... show more

    • Battery life, charging, wear and tear.
I've had the phone case since February 29th and with a couple weeks in the takes forever to charge while barely charging the case and actual phone. 6hrs ish and I've got 56% on my phone one light on the case. As for wear and tear around the edges of the camera and phone it's begone to peel. The case was great the first two weeks but as of March 18th I'm looking for a replacement because the charge time is atrocious. ... show more

    • Works as stated
I am at lots of kids sporting events. I can spend from 8am to 5pm at these events. I use my phone for recording posting to social media, phone calls, and playing online games. It works like a charm to get me through the day. These all drain my phone battery heavily and I always have to use the battery to charge. ... show more

    • Good enough
Works for the most part. The charging has moments where itll constantly disconnect ans reconnect making it very annoying especially if you trying to watch something. I don't know how well the data sync works but I do know when I use a headphone adapter that connects to the data/charging port ...it doesn't work. I have to take my phone out of the case and connect it directly to the phone to use my headphone.. I don't like wireless headphones as they tend to die too fast ... show more

    • Just got it and 10 secs later wrote the review
It's extremely bulky. Extremely. Overkill in the pocket. Super sought fit. Has a charge coming out of the box but, NO CHARGER!!!! Uses type c charger so I can use my phone but I was hoping for another charger cord so I wouldn't have to purchase myself. Separately.

    • PEACE OF MIND
Mid day I'd have to run to my charger because my Note 20 plus was losing power. I'd plug it in and walk away to get things done and run to it if it rings. Since I got this charger I don't have to use my wall charger for a few days. This is great I just push the button on the back and my phone case starts charging. And as an added benefit, it serves as a protective case for my phone. WOW! I'm loving the convenience. ... show more

    • Looks great but has some unworkable inconveniences
It's got a pretty big battery inside and it charges the phone quickly. I get probably an extra several hours worth of power out of this battery. However, the downsides are pretty extreme. Firstly, the texture of the case feels nice but it's very slippery. It's very challenging to get the phone in and out of the case which wouldn't be a problem if I didn't have to do it every single time. I have plugged this case into every charging port that I have that'll fit it and it seems like my phone charges but the case doesn't. I tried pushing the button to maybe disconnect the case from the phone so it could charge itself but it still wouldn't charge. This means I would have to take my phone out of the case every night, risk dropping it in the night, and have two USB C ports by my bed. The quality feels great the case looks phenomenal but it just is not convenient in the way that I am needing. In addition to this, once the case starts to die it flashes my phone on and off over and over again as it attempts to charge and then stops and then starts and then stops. Even when it was fully charged, it seemed to be charging my phone and reconnecting every 30 seconds or so. I had to turn the charging sound off on my phone otherwise it drove me nuts. Overall, I feel like this case needed better programming to be able to charge efficiently. It needs to know when the phone needs to be charged versus the case and it needs to charge consistently like a power bank does rather than starting and stopping every 30 seconds. rather than starting and stopping every 30 seconds. ... show more
