Replacement 3.7V 2450mAh Battery for Samsung i9100 Galaxy S2 - Golden

Pros: High endurance for Samsung Galaxy S2. from 12 hours with full use upgraded to 18 hours with the same battery weigth. Golden color is not a problem for the day to day use.

Cons: After 1 month using this one, baterry does not work more than 15 hours with the same kind of use. I bought 5 more to check if is the charging process or what. I test them on 5 differents Samsung Galaxy S2 with 2.3.6, 4.0.3 and 4.0.4 Android version to be sure if the issue appears only on my cell phone or others.

Other: I will buy more of this slim baterry. 6 hours more on the cell phone without change his original line is a very good idea for this.

Pros: It works. But the actual experience with it is not different from the regular battery - no improvement in time before recharge is needed. Most probably it is not a High Cpapacity battery.

Cons: The price is too high, if all you get is a yellow color of the battery, not the longer life.

Other: Better buy a regular battery - at least the price is better and there are no expectations and no disappointment.

Pros: It's extra juice gives you the comfort of knowing that you're fully equipped for the long haul. You really notice the difference form the very start. It's a great jump from the original battery that comes with the phone.

Cons: Although the juice is extended. It won't go a full 24 hrs. Once still need both batteries on hand for problem free battery concern.

Other: Price vs quality relationship means this is a great deal. Beats carrying power cord around and hoping to be able to charge.

Pros: It is a good battery, greatly increased load capacity over the original battery, even using 3G internet, GPS and Wi-fi notice a nice income. The price is also very attractive, with a battery capacity that is very hard to find and when you find it's costing a price much higher than the price offered by "DealExtreme"

Cons: Despite scoring the capacity of 2450 mAh, this battery does not have all this capacity, compared to original battery it should last twice as long as the original, but it's not what happens today, I would say that this battery lasts about 25% more than the original So it's good you do not delete your original battery, with two loaded walk in the backpack is a good idea.

Other: good price good quality And very useful

Pros: Works/charges without issues or problems. Fit's perfectly in the phone and it does not get hot or anything

Cons: the capacity is defenitly not 2450 mah. I didn't messure it but i think it's about the same as the standard i9100 battery. It just about get's me trough the day with heavy use.

Other: overall i'm pretty satisfied. I bought two of these so i always have power for my smartphone

Pros: It doesn't get hot, it has the right size so there is no need to change the back faceplate, it lasts a little longer than the original battery. The most remarkable: It's cheap

Cons: With 2450 mAh it should last a lot more, it's definitely just a number, it's not real.

Other: Based on the price I feel satisfied, now i keep the two batteries with me and I have battery backup for those days when usually I was with no cell phone at 5pm. Buy it it you are looking for an extra battery, don't buy it if you want to replace your original battery with a high capacity one.

Pros: It is a good battery, great load capacity over the original battery, .The price is also very attractive, with a battery capacity that is very hard to find and when you find it's costing a price much higher than the price offered by "DealExtreme"

Cons: Not 2450 mah. I didn't messure it but i think it's about the same as the standard i9100 battery. It just about get's me trough the day with heavy use.

Other: Great Battery

Pros: It's a super high capacity battery, I don't know if it's exactly 2450mAh, but definitely it's higher than vanilla one. Other non-original batteries may produce high-low voltage, which may cause momentary bright variations, this one doesn't produce that.

Cons: If I had to say, the paper cover is easily removed, but not so bad.

Other: It's a super high capacity battery, I don't know if it's exactly 2450mAh, but definitely it's higher than vanilla one.

Pros: It's a really good battery, really good to replace te original one! if you get out of battery or are you looking for a second battery you really need to buy it. Overall it's really in good price.

Cons: It's a little bit difficult to make it get in the phone, beacuse of the battery the back case don't fit really good, and i doubt it´s really a 2000mAh, but still have a good battery life :)

Other: perfect for Samsung s2

Pros: Normal battery. Good size, do not change the back cover of the phone. When charging is not heated, it is a positive feature. and very good price.

Cons: Battery lasts longer than the original 1300 mAh battery. I did not measure capacity, but based on previous experience with the original battery, I believe that that capacity in 2450 is not true. It should withstand almost twice as long, but it will not last.

Other: Good replacement for the original battery. Capacity reaches the value of 2450 mAh. But when I look at the price of the original battery, I think that "Gold Bater" from Deal Extreme is a good choice.
