I blogged on this on July 10, 2016. The battery worked fine for over a year. Today I noticed the phone was warm and I popped the cover to find this battery swollen. It looked just like the Samsung battery it replaced. I don't know if it is an inherent flaw in the S4 or if the battery is defective. I do know that the RAVPower website has not warranty information on the battery. So buyer BEWARE this may not be the product for you and BEWARE of a company that doesn't have clear warranty information on their web site.
RAVPower 2800mah Samsung Galaxy S4 Replacement Battery for
I9500, I9505, Sgh-m919 (T-mobile), Sch-i545 (Verizon), Sgh-i337 (At&t),
Sph-l720 (Sprint), with NFC [Not for Galaxy S4 Active or S4 Mini]
This battery is charging well and is a great replacement for the faulty batteries that came in the Samsung S4. After my phone shut down and I opened the case to see the severely bulged battery, I googled the issue and discovered that the bulging battery was a known Samsung issue. After considering a OEM replacement battery, I decided it made no sense to get a battery identical to the one that failed. I searched the compatible batteries on Amazon and this battery had significantly more positive reviews than most other batteries.
The price was attractive although with Amazon's new $49.00 minimum for free shipping, I was forced to use an alternative vendor and pay for shipping. Frankly I almost made the purchase on eBay since there was free shipping on several batteries but this battery seemed better.
I am happy with the battery and the pop in replacement factor. I have not seen any increase in longevity with the battery even after multiple recharges. Even with expedited shipping this battery cost me approximately $20. I called several local wireless stores and the cheapest replacement battery was $40.00. It mystifies me why so many mortar and brick stores lose so much business by grossly overpricing their goods. Even if they paid the same for the battery as I did without the expedited shipping they would make a hefty 100% profit. Instead they don't sell a battery and keep fueling the expansion of Internet business. Having had a brick and mortar location when I was in the computer business, it pains me to see such a lack of foresight.
I recommend this battery based on my experience.
