15500mAh Super Capacity Battery Compatible with iPhone 12/12 Pro, 0 Cycle Li-Polymer Replacement Battery for iPhone 12/12 Pro, with Professional Repair Tool Kit

Arctis Nova Pro Wireless are amazing for the fact that they can dual function both a Bluetooth device and an input on the DAC. Amazing headphones. The dual battery is also amazing in the fact that you never have to wait for them to charge as when one battery depletes you simply swap to the second.I use these headphones for sometimes over 10+ hours a day for work and play. The included 700mah batteries lasted about 7-10 hours depending on if I had both bluetooth hooked up and my pc. The batteries started to show wear after probably 1.5 years being used just about everyday. I somehow misplaced one of my batteries while traveling, so I had to purchase a second set to get back the uninterrupted use again.So far these replacements are working well. The DAC charges these without issue same as the OEM batteries. I charged them and started to use one yesterday, and its still got 2 bars on the battery and about where I would normally need to swap, so these do seem to have a longer runtime than the OEM. Hoping they hold up over the time, but so far, very pleased.

As a plain battery this is fine, BUT, if you want to use it in an iPhone (and have your iPhone work) then don't get this. Unfortunately I recycled the old battery too hastily, otherwise I would put the old one back in. Though my phone technically "works" many functions have been compromised. The right side button now does not work so I must wait for the phone to time off and also can no longer take screenshots. on phone calls, after a maximum of 2 minutes, my phone now shuts off and restarts itself. It does the same thing when taking pictures and videos. This is all super annoying and now makes the phone useless as a phone. I replaced according to instructions (and Youtube videos were also helpful), the battery does charge and has a better life than the old one but if you want your phone to function properly, DO NOT Get this battery. Additionally, since I waited too long after delivery and not replacing the battery immediately, l missed the return date.

The media could not be loaded. The only problem with this battery is that it doesn't meet my expectations for capacity. I initially thought it would have double the mAh of the original Samsung Galaxy battery, but it turned out to be less. After a few uses, the original battery in my phone, which I've used for over six years, has degraded from lasting about six hours to around three or four hours. I hoped the new 10,000 mAh battery would last approximately eight hours based on simple calculations, but that’s not the case.Charging the battery to around 85% provides the best protection, but even when fully charged to 100%, it only lasts about six to seven hours instead of the expected twelve hours. This shorter lifespan is disappointing, but understandable given that it’s a cheaper battery.The charging speed is satisfactory. However, it's important to avoid letting the battery drain to zero or overcharging it, as these practices can cause micro-damages that reduce the battery's duration, lifespan, and capacity.

Good replacement battery. Fit perfectly; hold charge all day! Much cheaper than apple’s store and really easy to replace. Just need a little patience and follow instructions.

I had replaced the original battery 2 yeas ago, but need a new one. Tho tool kit was ok but I used the better tools from last time. This new battery charged ok but suddenly discharged completely at 10%, leaving me stranded. I am now recharging around 20% and no issues. Just be aware this battery is good but not great.

These replacement batteries work for the Arctis Nova Pro Wireless but i use my headsets literally alll day, i work from home and game during and before my shift. I use Bluetooth during this time as well for my headset. I was able to get 17hrs of use before the headset started beeping which means the battery is low. For this to be a 3000mah battery this is not ideal but gets the job done, the original SteelSeries battery is less than 800mah and is advertised to last 22hrs.. I'm happy but expected more.

the capacity is not what it claims; it does charge fast, but it also drains fast, the phone goes off after chatting on full battery for 90 minutes. what's worst? the tools are cheaply made, screwed up the phone screws and the tool somehow broke the home button connection. i have been replacing my phone battery for 5+ times with success, this is the only time that the product screwed it up.

Charged properly and is a powerful replacement to the stock Fuji battery. We took 3 to Alaska. Best to carry 2 for 8 hours of use.
