2500mAh Super Capacity Battery Compatible with iPhone 4S, 0 Cycle Li-Polymer Replacement Battery for iPhone 4S, with Professional Repair Tool Kit

Bought this as a replacement for my switch as my original battery was swollen and causing my Switch to burst out at the seams and the bad battery got to the point where my Switch wouldn't even turn on cause it seem the old battery wasn't taking a charge. Bought this nice battery replacement installation was easy just follow some guide on youtube, my switch is now back in working order turning on. I can get hours worth of gaming on a single charge, and the tools that came with it was a nice addition. Been only using it for a few months but so far so good.

I installed this battery in my iPhone SE (1st gen), and the phone has been completely unstable ever since. Even at 100% charge, it shuts off while doing simple things like going through settings or trying to add an Apple ID. It doesn’t even have to be under heavy use — just navigating menus causes it to die instantly.The battery claims to be 11000mAh, which is 100% fake. The original iPhone SE battery is only around 1600mAh. This kind of false spec is a major red flag and shows that the product is not trustworthy or safe.The shutdowns make the phone unusable, and I ended up having to remove the battery and look for a proper, high-quality replacement. This product should not be listed — it’s misleading, potentially harmful, and wastes your time and money.Do not buy this battery. Spend a few more dollars and get one from iFixit or another reputable source. Amazon needs to take these listings down.

Both batteries for My Arctis Nova Wireless pro died at the same time, these kept it going.

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.

Great kit to help replace the batter and works but it is only 4400 mah not the advertised 11000 mah

They're decent, one seems to not hold as much charge as the other, even after discharging fully upon arrival like instructed... but I'm glad to have my camera back, so can't complain too much

I liked that it came in a nice package very professional came nice and new even smells new lol easy to put in really all you have to do is take off the battery dont have to do what all these YouTube videos tell you you have to do like taking the charging port out and everything like that just unplug the battery and boom take it gently though he might be hard because of the adhesive but after that your ready just buy a new battery and apply new adhesive to it and there you go easy and ready to use I thought it was not going to work at first but I was wrong it works so yeah thank you for the good battery and it had less reviews then the other ones I was looking at the other ones had more bad reviews and more reviews so I think this is the best one base on the reviews because I just really had to make a risk and it worked very happy definitely be buying more battery and my batteries from these guys no one else good price to very affordable and also it fits perfect just like the apple iPhone battery one thing to know though it dont show the battery life but it really dont matter if you dont really care about that but it does show you the percentage of the battery if that's helps but over all nothing to worry about also dont even heat up well it does a little but calm down after a 1min so really dont have to worry about the phone exploding in your hand lol.

It is NOT as advertised. It last about 10 to 12 hours – when the EOM lasted 17- 20 hours The OEM was rated at 700mAh and this at falsely rated at 3000mAh. That is a lie and why I give it a 1 star. It does work for a reduced amount of time – but the case is de-laminating and will be unsafe when it does. Used it for about a month and I use them every day, so initial charge cycles did not improve anything. It IS a mediocre battery and as such does its’ job. But it is being sold as a premium battery – which it is not.
