## Customer Reviews

### ⭐⭐⭐⭐ Definitely a better long lasting battery but will not fit any cases
        
*by R***S on June 22, 2013*

I bought this battery for the extended life it would offer in a Samsung galaxy S2 smart phone. Although the phone is only used for a few texts and calls each day, I can go 2 days or more without charging - seems like under heavy use it would last quite a bit longer than one day, Friends with regular batteries sometimes have to re-charge the same phone before one day of use is done. The only downside and I was really surprised no one - not even Laza - has addressed is that  they provide the new thicker back cover for the phone but for the S2 they offer no cases or covers that will fit the thicker phone and none can be found anywhere.This phone is used by my wife so she ended up having to get a new small carry all purse/wallet with a thin shoulder strap to carry the phone and her wallet items. Cases are offered for the S4 but none for the S2 - that was very discouraging and I cannot imagine why they pass on that extra business and don;t provide any protective cases for the S2 with the Laza extended battery and case. - for that reason I give this product a 4 instead of a 5. It cost us a lot of time and searching to come up with a protective case and carrying solution.
  

### ⭐⭐⭐⭐⭐ Excellent improvement over the original battery
        
*by B***O on May 20, 2014*

I'm as pleased as I can imagine being with a cell phone battery.  After years of daily recharging and, often enough running out of "juice" before day's end, it is really nice to go for relatively prolonged periods of not being nervous about my phone dying inconveniently.  I'm not a heavy user of my cell phone and usually get 2 days (or more) out of a charge.  With heavy use, the battery still lasts well into the 2nd day.The battery and back that came together both fit well enough.  One issue is that the back is very difficult to remove (compared to the original Samsung back).  But that's preferable to having it be too easy to remove.Prior to installing the Laza battery and back, I used a super-protective "Otterbox" like case.  Then went with a simple silicone back cover which proved to be adequate protection.  Not being able to use such a cover was a rather strong concern as I considered buying the Laza battery / back.  However, it seems that the new configuration (with the Laza battery and back) gives my phone a certain "heft" that lets me pick it up and hold it without the same concerns for dropping it as was the case previously.  So, if the change to the Laza products isn't "magical", it has certainly been most satisfactory.  Good job, Laza!  And thanks to other Amazon reviewers who pointed out the benefits of this product.  You helped me make a very good choice.
  

### ⭐⭐⭐⭐⭐ Double the life
        
*by J***Y on February 27, 2013*

I love my Samsung Galaxy SII, but the battery life is poor. I rarely make calls, but do use various applications and check emails and Facebook a lot during the day. I also play the music while using an app that tracks my exercise. It gets a lot more use than my previous not so smart phones, but poor battery life is the price I paid. The low battery alarm would go off by dinnertime and I would have to put it in the charger before I was ready to retire each night.The replacement battery goes 2 full days without needing a charge. That is much better, and I don't have to worry about the battery dyeing before the end of one day any more.The only issue is that I can only find one protective wrap that will fit around the larger extended battery case and reviews of that are not so great. I miss being able to add one of the case protectors I was able to use with the standard battery. I'll just have to be more careful!
