First one good enough for me to take a third chance
The last one I got craped out on me. Going to try again because the other one is still going strong and impressive. This last one only lasted a few months but willing to take a chance on a new one because the first one is performing so well.

The poorest quality of battery in the market
I bought this same charger more than a year ago and it lasted a long time until it was damaged by so much use. I decided to buy another one since I trusted the quality of the first time. I looked at some bad reviews but I didn't take it seriously. Now after buying it and I wanted to use it after 3 minutes or less it automatically stopped charging which is very annoying because I had to turn it on and on every now and then. If the company of these chargers/ devices look at so many defects or bad reviews why don't they update the way they charge their chargers for a batter performance. That way you win and so do we. But if not.. one as a customer gets frustrated and the loss is for you. Improve the quality of your products.

Replaced my old one due to damage but not Mfgr fault.
Review for NEWDERY Battery Case for iPhone 15 Pro Max/iPhone 15 Plus 10000mAh I recently purchased the NEWDERY Battery Case for my iPhone 15 Pro Max after my previous case was damaged, and I couldn’t be happier with my decision. This case is a game-changer! The 10000mAh battery capacity ensures my phone stays charged all day, even with heavy use. The USB C and magnetic Qi wireless charging features are incredibly convenient, making it easy to charge my phone without any hassle. The case itself is sturdy and well-built, providing excellent protection for my phone. Overall, this is a fantastic product that I highly recommend to anyone in need of a reliable and efficient battery case.

Hits the mark for the most part
Overall, this works ok. It doesn’t always charge perfectly on qi in my car, but I can’t necessarily fault newdry for it. It wouldn’t charge on one of my usb-c cables for some reason, but I tried another and it worked fine. Truly a 10000 mah battery, so it has some weight, and certainly the capacity to recharge my iPhone from dead a couple times and then some. Case itself seems durable and fits my iPhone 15 pro max very well. From a price perspective, this isn’t a bad deal. Maybe if it didn’t have the cable compatibility issue and the odd qi wireless function, I’d have given 5 stars.

Gives me an extra day or two over the standard 15 Pro Max phone internal battery
I have a consulting business that occasionally takes me away from home to a remote site for a night or two, and sometimes involves lengthly on-site phone calls and app usage. I needed sometthing unobtrusive (unlike a bulky external USB battery pack) to insure that the phone won't run out of juice, and this seemed to fit the bill. So far after two trips, it has earned its place in my travel bag.. I don't normally use the case when working at home, since it does increase the bulk when you carry the phone around. However, the good news is that, unlike some rigid battery cases I've had in the past, the flexible rubber top makes insertion and removal of the phone very easy. A note on charging: The battery case can be charged either wirelessly or through its USB-C port. When charging the EMPTY case either way, the case gets ...err...warm (as stated in the manual). When charging the case with the iPhone in it through USB-C, the case gets ...warm. BUT- when charging the case wirelessly with the iPhone (needing a charge) in it, the case gets....HOT (IMHO). Your mileage may vary, just my experience, albeit with a non-Apple Qi charger from China ($5 vs Apple's $39). In any case, normal charging protocols, like not keeping any Li-Ion battery always on a charger, should apply, since you don't know what kind of Battery Management System (BMS), if any, that the battery case has buried inside of it. So far so good- 5 stars from me...

Best battery case with MagSafe feature.
I recently got an iPhone battery case that's a game-changer. Priced like the cheapest OEM options, it gives my phone two full days of heavy use. What's even better is its MagSafe compatibility. It enables Night Mode when charging, supports MagSafe accessories like the vent clip in my car, and my Belkin MagSafe Camera Mount. I initially got it for trips, but it's now a permanent fixture on my iPhone. It's affordable, protective, and incredibly versatile. If you're have and use your MagSafe accessories on the daily basis, this is a must-have case.

Keeps disconnecting from wireless charging station!!
Keeps disconnecting when charging from a wireless magnet charging station. If you plan on charging from a magnet station don’t buy you’re just gonna return it like I’m doing. Very weak metal strip so the phone won’t stay on the magnet. All my other Cases no problem so it’s not the magnet charging station. I ask for a replacement case to see if it’s just one bad case. Second came in today same problem. I’m returning both and getting my money back. If you just plug it in it charges up quickly. If you charge the phone from the case great works great just not on a magnet charging station very bad. All night long you hear your phone disconnecting and reconnecting sound. Finally I just plugged it into a plug.

Buena para campo y por el precio, pero a los ~2 años se infló la batería y murió el Qi
Mi uso Soy biólogo y la compré para salidas a zonas sin electricidad. La usé diario en campo y ciudad. Cronología real • Dic 2023: compra. • Todo 2024: sin fallas; me salvó muchas veces lejos de enchufes ⛰️. • Inicios 2025: dejó de funcionar la carga inalámbrica (Qi), pero seguía cargando por cable sin problemas. • Sep–Oct 2025: la batería empezó a abombarse; la tapa trasera se ve hinchada y ya se fracturó el plástico. • Hoy: el “bumper” ya está algo suelto en partes, pero no empuja al iPhone por dentro y todavía puede cargar por cable. No sé la capacidad real actual, pero claramente ya no rinde como antes. Lo bueno ✅ • Precio justo para lo que ofrece. • Aguantadora: sobrevivió muchas caídas; la parte interna protegió muy bien el equipo. • Carga por cable estable incluso después de fallar el Qi. • Ideal para trabajo de campo y emergencias cuando no hay energía. Lo malo ❌ • Carga inalámbrica dejó de funcionar a menos de 2 años. • Inflado de batería alrededor de los 22 meses (provocó grieta en la tapa). • El bumper se aflojó con el tiempo y la carcasa se raya relativamente fácil. Veredicto Si buscas una opción económica que te saque del apuro durante 1–1.5 años, cumple. Pero si necesitas durabilidad de 2+ años y Qi funcionando, yo me iría por otra. Por el mismo precio actual, diría que sí cumplió su función, pero el abombamiento me obligará a reemplazarla. ⚖️ Nota de seguridad ⚠️ El abultamiento indica batería hinchada. Recomiendo dejar de usarla y contactar al vendedor/soporte para evitar riesgos (típico de baterías de litio cuando ya van de salida).

Best charging case bought yet.
Worth the price. A bit on the heavy side compared to my previous cases but much more durable & gives me 2 complete charges before having to charge both the case and phone again. Have not tried the magnet yet but have not needed to. If I do manage to break this one too, I will buy this exact case again, 10/10.

No se puede recargar.
Ya había visto opiniones de que llegó sin funcionar. Decidí tomar el riesgo y efectivamente. Llego sin funcionar. No se puede recargarla. Es decir. Llega con tantita carga. Y si la pasa al teléfono. Pero al conectarla para cargarse, no carga.

Awesome product
A bit bulky but I am used to it I have always used one. But you get 2-4 full charges you can take it away on a weekend camping and not have to worry if you have your phone charged or I use it all day for maps in my truck for work and never run out of battery would highly recommend
