I've had the phone idle for days and it stays at 100%, but then once I use it... it'll drop 30%+ within ten minutes. so I believe because it isn't an official battery, ios cannot reflect the correct % which isn't a huge deal, but something to keep in mind. if you're going to be spending the day with it.. just make sure you charge it for a few hours even if it says it's at 100%.i was able to record, using the memo app, 9 hours of audio recording when starting at 43% charge. i'm also able to play a good 12+ hours of youtube video via safari. i think it's probably because safari will only play 360p video since the iphone is so out of date.keep in mind, this phone can't use any apps because it doesn't get updates anymore and apps don't support it. only safari works for me. without safari, this iphone would be almost completely worthless. i am however using it for audio recording via the memo app and that works fine.depending on how long this battery lasts, i may buy another for my iphone 6s and iphone 5s. ### ⭐⭐⭐⭐⭐ Phone battery *by on Reviewed in the United States May 5, 2026* The battery charge holds up really well. The fit of the battery was perfect. No problems at all. Recommend to anyone needing a new phone battery ### ⭐⭐⭐⭐⭐ simple but no instructions *by on Reviewed in the United States May 9, 2026* great product. had all the tools needed. the only drawback there were no instructions. Simple enough i figured it out. --- ## 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.us/products/782683907-xyirmcyf-21800mah-super-capacity-battery-compatible-with-iphone-11-0](https://www.desertcart.us/products/782683907-xyirmcyf-21800mah-super-capacity-battery-compatible-with-iphone-11-0) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-04*
