The top is rubber and doesn't come apart so there's no way to lose the pieces which has been a problem with other battery cases. It barely adds any weight and is rubberized on the outside. It has an indicator for charge with a small button on back bottom that is very discrete. Love it!Update: The bottom metal charge piece snapped off in my phone so the case/battery is now worthless. ### ⭐ Negative update to my original review *by L***R on Reviewed in the United States on August 1, 2019* I have owned this product for just over 5 months. I noticed intermittent charging problems starting maybe 2 months ago. Now I cannot charge the battery case. That makes it completely useless for me. This is very disappointing. Below is my original review.I have only had this battery case for a few days. As I gain more experience with it, I may modify my comments. I saw another battery case with a bigger, longer lasting battery, but it was much heavier and thicker. I selected this one because I wanted one that wasn't too thick and heavy that it would be too bulky and heavy in a pocket. My other criteria is I wanted a battery case that would get me through an entire day and night without recharging. So far, this seems to fit my needs. it's a little thicker than a normal cell phone case. It adds some weight, but is not as heavy as the larger battery case I saw. I charged it and my phone (when the phone is in the case, it charges the phone first and then the battery case) the other night. When the phone battery power percentage was in single digits, I pressed the button on the case to charge the phone. it looks like I can get one full charge from the battery case with a small amount left for maybe a 10% additional charge. That seems more than sufficient for me. I am willing to trade battery life for less bulk and weight. I cannot speak about durability since I just received it this week. To charge the phone, you have to press the small button on the back of the case and press it again to turn off the charging function when done. Depending upon my usage, it seems the phone with the battery case lasts 2 to 3 days without having to plug it in. I am pleased. ### ⭐⭐⭐⭐ Thin and not heavy *by N***K on Reviewed in the United States on May 20, 2019* This case is really thin. Fits the phone tightly. It looks like a silicone case. Sides are solid but bottom and top, has only rubber. I thought that in such a thin case will not be a strong battery, but it is enough to charge my iPhone 7 plus for 100% with 15% if I don't not use the phone while charging from the case. --- ## 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/126773611-linasone-extended-battery-case-for-iphone-7-plus-8-plus](https://www.desertcart.co.uk/products/126773611-linasone-extended-battery-case-for-iphone-7-plus-8-plus) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
