I am a heavy user who uses my phone for various uses constantly. Overall, I find this battery to be OK, but not great or terrible, as many reviews indicate. First, they're absolutely no directions included, so unless you read amazon's website that tells you to charge it for ten hours straight the first three times you use it, you will be disappointed with the product, as it won't work correctly without that, at least per other reviewers posts. The fact that the seller doesn't include these instructions in the product itself is truly asinine and super lazy.Second, I did follow these instructions, but I did not get some giant superior performance out of this product that many say they get. Perhaps other users rarely use their phones. I personally check email, trade stock, read stories and use my phone quite a bit and under that sort of use, I get maybe 10%-15% more battery life than I did with the standard Galaxy S4 battery.Overall, this battery is a standard replacement for your normal battery and nothing more. The fact that packaging lacks any sort of instructions is truly lazy on the seller's part.Would I buy this battery again? No, I would not, I would search out a battery that actually lives up to its own hype or pay less for another battery that will perform the exact same. ### ⭐⭐⭐⭐⭐ Update ... Very impressed. Yes it is waaay better than stock. Recommended ! *by W***H on Reviewed in the United States πŸ‡ΊπŸ‡Έ on May 28, 2015* The battery was at 54% when it came in the mail. It took almost 13 hours for it to die with the phone on in standby, not really using it much.Charging now.Question is should I turn my phone on and continue charging or should it stay off. For maximum results I am leaving it off while charging until I receive some feedback. Might want to consider a wall charger for heavy users, or if you cant live without your phone ;)I should mention that I consider myself a power user, lots of apps, smart watch, bluetooth ear bud. Normally I am at 10% or lower after a hard day of use around 6pm5/31 Update I am starting the 3rd charging cycle now. Charged it completely while off. It lasted 28 hours or more. I actually fell asleep listening to Pandora. Took 4 hours to charge completely back up with the phone off. Loving it. Have to keep reminding myself that I don't need to be plugged in all the time.6/1 Update Just passed 5% after 24 hours of moderate use. If I forgot to put my phone on the charger, it was always dead by morning. Thanks seller. Buyers read the directions ! ### ⭐⭐ Not as Advertised *by A***T on Reviewed in the United States πŸ‡ΊπŸ‡Έ on November 15, 2015* Not as advertised. Maybe just a Defective Battery. Still better then my old batter not by much. After several days of use and testing the battery I get 2 1/2hours screen on time, 3 days screen off time (from estimated app time)my phone was maybe 15 hours. While the screen is off this battery holds its charge very well. Though while using it(Heavy use)discharges faster then my stock batter I get 3 1/2hours on heavy use. So kinda give an take with this battery. Also I did a little research and found this battery might last 100 charges before loosing life as it runs at 4330mv at a 100%. Premium batteries run at 4.2mv for a 500+ charge no life loss. And it only reads my batter at 2,945mah not the said 3900mah. So not happy with the battery but if your a light user this batter is for you.I will contact customer support and update as the situation continues. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/11347846-lomui-3900mah-battery-for-samsung-galaxy-s4-i9500-i9505-b600bc](https://www.desertcart.tn/products/11347846-lomui-3900mah-battery-for-samsung-galaxy-s4-i9500-i9505-b600bc) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-27*
