Batteries do last longer then my old original.
After couple of month i tend to think they dont hold charge as they did when new.
Nevertheless they are still better then the old original one.
The price is Great.

Having two batteries and the bat wall charger is amazing.
Im coming home after a long day pop a fresh battery in and vila my phone is fully recharged.
I dont have to wait for it to charge if i have to leave home quickly.

5.0 out of 5 stars Best battery ever!!! 2 Aug 2013

I'd give these batteries a 10+ stars if I could. I am amazed at how LONG of life they have. I keep an extra one charged in my purse for a back up. But so far after buying these well over a month ago, I have never had to use my spare one. AWESOME!!!

1.0 out of 5 stars Quickly fails to hold a charge 24 Oct 2013

This battery worked well at first. After a month the phone runs out of juice after about 12 hours of minimal use. The almost 2-year old Samsung extended battery works better than this 1 month old battery. Steer clear.

Charger failed after one week. Output was only 4V with no indication of charging. Save your money for something else. Charger current rating too low it takes a long time to charge batteries even if yours works.

5.0 out of 5 stars 2300mAh has got to be better then 2200mAh 2 Oct 2012

I have a Samsung SGH-i727 Skyrocket and as soon as I purchased the phone I started looking for a backup battery. I made it a practice to carry a spare charged battery at all times because when you compare how useful it is compared to how much space it takes up on your person it really is a no brainer. I originally bought another samsung brand battery because it was made by the company that made the phone so they should know what works best for the device. After a while of using 2 stock batteries a day I researched the extended slim batteries like this one. The OEM batteries are 1850 mAh and these are 2300 mAh but they are the width as the OEM so you don't have to replace the stock back and loose the sexy figure of the Rocket. I originally bought the Anker brand 2200 mAh batteries and they are another great product but these have an extra 100mAh so I bought them later and gave a friend the ankers. I can't help but picture SpinalTap where the guy is showing off his amps that go to 11. Ya these batteries go to 11! Is that extra 100mAh noticeable? I honestly can't say for certain but my understanding of numbers and math leads me to believe yes! The build of the batteries is actually very similar to the Ankers, In fact they both suffer the same flaw. on the top of the battery there is a plastic piece that separates the different spaces and if you use the the included charger you will break one of the separators off. This will happen with both Anker and ec technologies. I wrote to the company and got a reply the same day that the batteries are protected by a micro chip and that the separators are basically cosmetic. If you look at the phone you can see that there is no way the connectors are going to misalign with the battery regardless of separator or not. These batteries are going to improve your relationship with the skyrocket and get you through a day of heavy use with out a problem. On the updated stock Android 4.0 these will give you another 4 hours of use compared to OEM. I am using a custom ROM and I get 2 to 3 days on a single charge. That is with bluetooth on, wifi on, GPS on, and screen at 75%. I have not been able to say that I got multiple days on a single charge since I started using a smart phone. I still carry the other battery with me but I never have to use it unless I am seeing just how long I can go on a charge. If you are thinking about spending a little bit of money to greatly improve your device, look no further! The charger that comes with the batteries is almost as great a the batts. You can use it to charge just about any battery. This is great if you have lost that stupid cable that only charges that one thing, like I have countless times. I use the charger for my camera battery, other phone battery, and any random piece of tech I want to revive. The charger can run off an outlet and u can plug another usb cable into it and charge another device at the same time. if you don't have a plug u can use it by inserting a micro usb into the charger and the other end in a laptop of other computer. The charger also doesn't have a set positive or negative so it never really matters how put the battery into it. Dude why are you still reading this get the batteries and live a less stressful life!
