Yes, it does make the phone a little bulkier and heavier but you get much improved battery life and it is so much easier to keep a hold of. The original back felt quite slippery and always seemed on the verge of sliding out of your hand onto the pavement. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Great battery life. Makes the phone thicker, but not a big deal. Case feels cheap and lacks NFC. *by J***R on Reviewed in the United Kingdom on 28 July 2018* Love the extra battery life on an aging phone. Cases supplied are cheap feeling, but OK. They lack the NFC functionality the standard back case has.Does increase the thickness, but it's still thinner than a 3210 was back in the day. Would prefer if the case was only larger where the battery pokes out (like the iphone battery case), but this might have made it difficult to get in and out of a trouser pocket.Note: the included battery will come partially charged; this is normal (best practice for li-on/li-po batteries) and not something to leave a bad review about. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Excellent extended battery for the LG G4 *by W***K on Reviewed in the United Kingdom on 2 March 2018* Excellent extended battery for the LG G4. Lasts most of the day on heavy usage. Sure the larger size of the battery creates a bulk at the back, but this is nicely covered by the 2 cases included in the package. --- ## 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.tn/products/49647211-perfine-perfectly-compatible-lg-g4-bl-51yf-h818-h815-h811](https://www.desertcart.tn/products/49647211-perfine-perfectly-compatible-lg-g4-bl-51yf-h818-h815-h811) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-16*
