CoBattery comes with two batteries, so when the battery on your case is running low, you can swap for a fully charged battery. Your phone will always stay at 100%. From the Manufacturer Battery for days CoBattery comes with two 3,000 mAh batteries. That's a lot of juice. With that much battery life, you can go on a weekend trip without worrying about bringing along a charger. In day-to-day usage, we recommend leaving one battery at home in the charging dock. That way you can swap once a day and stay at 100%. Sexy lightning connector We started working on CoBattery because we were unhappy with the other battery cases on the market. They still required plugging in the phone every night and they all had a bulky chin at the bottom of the phone. We had trouble fitting those battery cases into our pockets! So we designed and created a custom lightning connector that is 1.5mm thin. You want extra battery life, not an extra inch on your phone. Easy swapping CoBattery comes with two batteries and swapping is easy. Swap our for a fully battery in under 5 seconds. Protective cover Accidents happen; we get that. CoBattery's durable plastic protects your phone from drops, dings, and divots. Risk-free trial Don't love it? Don't keep it! CoBattery comes with a 30-day risk-free refund. Boom! Rethinking Battery Life At CoBattery, we believe that battery anxiety should be extinct. Your phone is essential to your day-to-day life and you shouldn't have to worry that if you listen to music now, you won't be able to call a ride home tonight. Your phone should simply work. CoBattery ensures that you'll always have battery, no matter what you get up to. About the Startup Describe your product in 3 words. Infinite battery life How did you come up with the idea for this product? When Doug was using his Android phone, he bought some extra batteries from the manufacturer. The removable back on the phone allowed swapping batteries. So for a weekend trip, Doug would just pop in a few batteries in his backpack and he'd be ready to go. But on the iPhone you can't swap out the internal battery. And all other battery cases still require you to plug them in for hours a day. So we decided to make battery swapping for iPhone. What makes your product special? It's simple: with CoBattery you never have to plug in your phone again. Every other battery case requires plugging in your phone over night. And to use an external charger, you have to carry around and be plugged into some brick. What has been the best part of your startup experience? We have a growing group of customers who've loved CoBattery so much that they've decided to get it as gifts for their family and friends. Then they can easily swap batteries at their friends houses and truly never have to worry about their phone battery. That has been awesome for us to hear about. ## Features - About this item - Lightweight case that comes in under 5 ounce - CoBattery comes with two batteries so instead of plugging in your phone, you swap batteries instead - Slim lightning connector that doesn't add bulk to your case - CoBattery is an iPhone case with a swappable battery ## Images ![CoBattery iPhone 6 Plus/6S Plus Battery Case with Swappable Battery, Ultra Slim High-Capacity 3000 mAh Battery, Protective Charging Case, Never Plug in Your Phone Again - Image 1](https://images-na.ssl-images-amazon.com/images/I/61u%2BHWfR4%2BL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ CoBattery is my GoTo Phone Accessary *by J***O on Reviewed in the United States on November 30, 2017* Big Big Big fan of the CoBattery so far. I've been using it for the past couple of weeks and it's really saved my skin a couple of times. I don't have to worry about carrying a charging cord and cube anymore, I just walk out the door with the spare battery on hand. It charges my phone quickly and efficiently and I know it'll come in handy for upcoming camping and concert events. It'll charge my phone from 0% to 100% with one battery so having two with me always ensures I can go at least 3 days without having to charge it again.In terms of the case itself I like the black matte finish and it is comfortable to hold. It's minimalistic and has a good feel to it. But because it's minimalistic it doesn't provide the utmost protection. I've dropped my phone a couple of times and while it's done a decent job of protecting it so far it doesn't have the same protection as other cases.The battery itself is lightweight. When the whole system is in place (battery, case, and phone) it does have a heavier feel to it, which I personally like. The charging port is durable and has withstood a lot of use so I'm sure this case will last me a good while. The batteries also hold up well and besides a little peeling of the label (happens when you remove the battery from the case) it looks and performs well. One thing that I would like to see improved is the issue of overheating of the battery/phone. When you have system like this in place, it's hard to avoid overheating since both batteries are so close to each other. I usually just remove the CoBattery until it cools down and put it back in after.Overall, I like this product and will be using it as my day to day case. The minor issues with it are outweighed by the benefits it provides and I would/already am recommending it to my friends. ### ⭐⭐⭐⭐⭐ Power *by L***. on Reviewed in the United States on November 19, 2017* Best battery pack in the market for sure, your battery will be 100% 24/7 no joke. The case does bot protect very well though ### ⭐⭐⭐⭐ Needless to say I'm impressed. *by B***S on Reviewed in the United States on April 7, 2017* Your browser does not support HTML5 video.  Breathed new life into my well-used iPhone.Tested the length a single battery lasted me, and here's what I found:It made my iPhone 6S last over 48 hours! The iphone thought it was plugged in and charging the whole time--it effectively avoided the entire batter.- That's on "low-power mode.- On all night (using a sleeping app to track my sleep cycle)- Intermediately watching YouTube videos, on Facebook, and took about 5 phone calls.When the batter pack finally did die, it should switched over to my internal battery. So technically it the batter pack lasted me 48 hours PLUS whatever was left on my internal battery. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/43001790-cobattery-iphone-6-plus-6s-plus-battery-case-with-swappable](https://www.desertcart.co.uk/products/43001790-cobattery-iphone-6-plus-6s-plus-battery-case-with-swappable) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
