I got the UK version of the galaxy s2. I got the kit in today, but I had no idea how to charge the battery on the charger, the pins move, and well I wasted a lot of time... There is no how to information given (there should be!) I have not had the time to test the battery, I will report back after 1 or 2 weeks.

10/8/2011

Two days now, and the batteries rock.. I'll still report back in two Weeks but as got now... I'm getting about 20 hours with medium to heavy use.. On my Samsung battery I get about 16 hours.. Keep in mind I've only had the Anker batteries two days though.. You ask have my promise I will report back in two Weeks time.

So far these batteries have held up well, with VERY GOOD life, I would say it was worth the buy. If anything changes, I will update, but for now, I would have to say for $25.00 you get some good quality batteries, I don't trust off brands batteries with my electronics, but these Ankers are good quality, for sure.

01/01/2012 UPDATE

ok so everything was working fine, better than the original battery for sure. However one of the batteries can't hold a charge anymore... It will charge and when I put it in the phone it will run down to 0% in less than 10 minutes. Also the only way to charge the batteries is in the charging dock, as plugging it in, the phone will not charge the anker batteries. This has been ok since I keep swapping them out, but now that I only have one, and tried to charge it last night, it would not do it. One battery still works good, however it needs to be put on the dock, so I'm swapping the original with the Anker.

Would I buy again?

Kudos for getting it to me in a timely manner, well packaged, and fully charged to boot, when I put it in my S2, it about gave me a heart attack as the phone buzzed and wouldn't turn on for anything. When I put the ORIGINAL battery back in the phone...nothin'! It took me about 20 minutes to mess with it, but I finally got it to turn back on.

That said, $30 later, I still don't have any replacement batteries for my Galaxy.

**UPDATE**

The seller contacted me on their own after reading my above review. After asking me some specifics, they volunteered to replace the batteries for me, which they did promptly. The new batteries arrived, again, well packaged and pre-charged, and THEY WORK in my phone!!

I've got to say, I was just going to leave well enough alone and chalk it up to a lesson learned, but I'm impressed that the seller reads their reviews and takes it all to heart, and follows up, and the follows up again. That's how to run a business!

These batteries are the best, they last longer than stock ones, about 2 hours more. I have been using my galaxy s2, with heavy usage for about 14 hours, modding the kernel, flashing, wifi, gaming, also IM, and at the end still have charge (14%). I recommend anker batteries. Also the charger have a led indicator.

I received my batteries like 2 months ago and I was loving them!

Unfortunately, today, I was charging my phone which was using one of the ANKER batteries directly from my laptop. I don't know if I shouldn't have done this, but I don't remember seeing a warning about that in the batteries packaging or anything. Anyway, I was in a conference call and the phone's screen lit with a battery image on the screen, and it turned off immediately. It caught my attention and I grabbed the phone and it was soooo hot. I honestly don't remember now if I turned the phone off myself or whether it was automatically turned off. I did unplugged it though, and when I flipped it I noticed there was a bump, as if the battery had expanded some how. That is exactly what it happened. When I got the battery off it was "inflated" and deformed. My phone was so hot I feared it wouldn't work anymore.

I let the phone cool off and then I used my original battery to turn it on. Thankfully it is working perfectly. The ANKER battery however, while has returned to its regular form, has a sort of fold in the base. I am never using it again.

Please note this. Like I said, before this incident I was loving my batteries, and perhaps you will to. But if you do buy them, remember to never charge your phone while it is using one of them. Better use the charger they come with.

UPDATE:
After I wrote this review, the seller promptly contacted me asking about the problems I was having. After hearing my story, they explained such problems are rather rare, but sometimes do happen. And I agree, no product is 100% fail proof.

These batteries seem to last at least as long as the stock battery and cost a small fraction of the price. The charger is a bonus that allows charging the spares out of the phone for true always-ready backup. The charger seems to work perfectly (I've only used it once) and is more compact than my other universal battery charger. You really can't beat this combo for quality, especially at this price ($19.99 and free shipping).
