4.0 out of 5 stars Improvement!, 10 April 2014
Verified Purchase(What is this?)
This review is from: RAVPower 5200mAh Extended Battery for Samsung Galaxy S4 with NFC + White Back Cover (Wireless Phone Accessory)
I purchased this product because my Samsung Galaxy S4 started to behave erratically following the KitKat upgrade. The phone turned itself off and on in a loop without initialising. The problem appeared to be the standard battery. The issue was solved with this product. It is premature to determine just how long the battery lasts, but I can confidently say that it is a huge improvement on the standard battery. Samsung developed a great smartphone, but battery power drains quickly with the demanding operating system. The only downside is that with the new back cover, the phone no longer fits into the protective cover I purchased. On the other hand - the phone feels more secure and substantial in the hand. Until either Google or Samsung finds a solution for the battery issue, this product is the way to go.
