If you're thinking of getting this battery for your Galaxy S2, just do it... I was fighting with low battery life since I got the phone... everything killed my battery... from video to live wallpaper... I even bought an extra charger and a car charger so I could top up my battery on the go...
This battery does not add any noticeable weight and in my opinion, the feel of the phone with the new back piece is better than the old one. It feels more solid and easier to hold. I've got an average sized palm and the phone felt thin... at first it was nice to feel a phone so thin and light... but eventually you get over it and it feels strange.
All in all, a great upgrade... I'd definitely recommend it. It should have been the battery and back shipped with the phone... it's that good!

UPDATE: My phone is the GT-I9100, bought unlocked on Amazon.

UPDATE: I went out of town and forgot my charger... with this battery, I was able to last 2 days and the only change I made was to disable WiFi until I got back to town... with the original battery, my phone wouldn't have lasted a day.

I use the phone for work and I'm constantly sync with my job email and have to download a lot of files, original battery would give me max 11 hours with this battery I get to 23 - 26 hours.

With no doubt, this battery increased the lifespan between charges of my SGSII. With a moderate use, now I got 20%-30% of energy remaining when I go to sleep (aprox. 15 h of use). The Cover is the same quality as the original, and does not add an annoying extra bulky appearance to the phone.

Since this is a Samsung brand battery and cover, everything fits as it should. The thickness of the phone is barely any thicker, but my protective case doesn't fit properly anymore. Not a big deal though. My phone was dying by 6:00 pm every night, but now I still have 40% at 10:00 pm.

I always felt that the Galaxy S2 was designed to have a flat body, but someone thought they would reduce the size buy making that silly 'dip'. I felt that this also limited the size of the battery, which resulted in a less than ideal battery life.
Well, this 2000mAh battery fixes this. The back cover fits perfectly, so as to make your phone look like the original. The cover simply makes the back flat, instead of dipped. The battery adds enough power to make the phone useful. I find that with moderate use, that instead of coming home with 10% battery, that I am finding about 30% remaining. Cheers.

Nice that it came with a new back for the phone, which is necessary. The only downside is that it weighs a little more, but hey, that's what you get when you have a larger battery! Otherwise, perfect. Glad I purchased!

Product was delivered on scheduled time, arrived to my country some days later due to international courier delays. When I received it I was amazed, the product is exactly the same as advertised on Amazon. Tested it for a few days. I've gone thru 15 charge cycles and I think this battery has reached it full potential. The battery lasts for a full working day, starting at 100% by 08:00am and ending the day by 11:00pm with 6-10%, time to go to bed and charge it again. With the stock battery I could have the same battery life but using the phone far more less. I'm happy with this battery, I recoomend it. The included back cover looks like the original, fits perfect and you can hardly note a difference in the phone weight and width.

I was interested in a extended battery since my phone ended up dead around 4-5pm every day. ordered the official extended because i did not want those extremely big third party ones with the big back, the slimness of the phone was very important for me, and i'm happy to report that, it's only been a couple of days but i can already see the difference, my phone now lasts all day long, only requiring charge around 10-11pm, and that's really all i needed, since i'm on the road and don't have access to a charger except when i'm home. overall very satisfied!
