NEWDERYBattery Case for Galaxy S23 Ultra 10000mAh, Qi Wireless Charging, Fast Charging, Sync Data Supported, Powerful Portable Rechargeable Charger Case for Samsung S23 Ultra 5G 6.8" Black

This battery works great, the battery last more than a work day +8h under heavy use. The wireless charging is normal speed but is OK, cable charging is fast and it will charge the the phone and case in about 2.5-3 hours. Now I purchased this case for about 8 months ago and one day it only slow charge and the next day it won't charge, I emailed the seller/company and after a a few emails they send me a free replacement in less than 3 days. Over all I give the case and support from the seller/company 5 🌟 and will buy their case again when I replace my phone to a newer model 🤙

I'm a warehouse manager/forklift operator so it get heavily abused I have a magnet mount on my lift and use it with this battery case product I've owned 3 so all three have lasted me just over a year each with heavy use bouncing around getting dropped 5 to 10 times a week all year long never once had a cracked screen so it does a good job with edge protection they charge my phone 4 or 5 times from 15% phone life the battery in the case has never failed or shown signs of degrade and everyone who holds my phone says it is heavy but I'm so used to it if the battery case isn't on the phone it's uncomfortable for me I'm super happy with this phone case I will always seek out this product with every phone upgrade because I am a very heavy phone user for work and can not be without my phone it works great for camping and getaways also

This product was treated very well and was never exposed to extreme environments. For some reason, after about 5 months, it completely stopped working... The product has a full charge and when I turn it on to charge my phone, my phone recognizes the charge for about 2 seconds and then it turns off. I have checked my phone and the phone is fine and I am able to use other chargers and peripherals with my phone. Only this product is no longer working.

This is my third Newdery battery case I have purchased. The other two were for previous Samsung phones and proved to be very useful on days you need your phone all day with no access to an outlet. This new one performed as well as the previous ones. I don't use this case as my daily case because it is a little bulky and heavy but on the days I do use it I'm very glad that I have it knowing that my phone won't die. Charging the battery case as well as operating it is very simple.

I recently had the opportunity to use the NEWDERY Galaxy S23 Ultra Battery Case, and overall, it proved to be a handy companion for my smartphone. Here's a detailed review based on my personal experiences.Firstly, the wireless charging feature provided by the battery case was a standout feature for me. It made charging my Galaxy S23 Ultra hassle-free and eliminated the need for cables. I appreciated the convenience and efficiency it offered.Additionally, the case allowed easy access to the S Pen, which was a major plus point for me. It ensured that I could quickly retrieve and use the S Pen whenever I needed it, without any hindrance or inconvenience.In terms of the case's build quality, I found the feel of the plastic to be quite comfortable. The material had a nice tactile sensation that added to the overall user experience. It provided a good grip and didn't feel overly bulky, which was appreciated.However, one drawback that I encountered with this battery case was the signal blocking issue when it came to NFC. Unfortunately, with the case on, NFC functionality was significantly hindered or rendered unusable. This limitation was disappointing, as NFC is increasingly used for various purposes like contactless payments, transit passes, and other convenient applications.In conclusion, the NEWDERY Galaxy S23 Ultra Battery Case offers several notable features that enhance the overall usability of the Galaxy S23 Ultra. The wireless charging capability, easy S Pen access, and comfortable plastic feel make it a practical choice. However, the signal-blocking effect on NFC functionality is a notable drawback that potential buyers should consider, especially if NFC usage is important to them.Despite this drawback, if you prioritize wireless charging, S Pen accessibility, and are willing to compromise on NFC functionality, the NEWDERY Galaxy S23 Ultra Battery Case can be a beneficial addition to your smartphone accessories.

He liked it and it worked well on my cell phone.

This is 2018 technology! Do not let them fool you! Does it charge my s23u yes! Does it do so efficiently no! It still requires USB to c to charges getting it to fully charge is a challenge! I cannot even plug this into a Samsung quick charger USB 18w charger. The trick is to find a charger that still outputs enough to charge this beast of a battery but not to much that the tech on the board internally isn't overpowered! This is a great in case of battery case but if they want to charge 50 bucks for this they should give it the ability to charge on a USB c pd charger and they don't. Please keep in mind this was alo my second one of these as the first one would not charge no matter which charger I tried. ( I tried 6 to be exact) for 50 bucks at this level of charging te h I should got a 20,000mah battery not 10kmah. Either fix the internals double the battery size or fix the sales page. I will be. Contacting both the seller and Amazon about these issues. Will update once I hear back.

Life saver. Would buy again for my next phone
