Default [REVIEW] 3500 mAh Chinese battery - India

Hi Guys,

After searching for Samsung made 2000 mAh extended battery in Bangalore for few days, I gave up and settled with something else. I thought I will buy Anker batteries but couldnt find any good deal.
Eventually I ended up buying 3500 mAh extended battery + backpanel from this link - http://www.ebay.in/itm/SAMSUNG-GALAX...cfd2713&_uhb=1

This is a Chinese battery and I did not expect it to be full 3500 mAh but anything above 2500 mAh was fine with me. The prices mentioned at the above link are varying bigtime - I bought it in 1039 INR, 2 days back it was 888 and now its INR 1200.

The bulky backpanel is a must to house this extended battery because of which-
1) Phone becomes quite heavy
2) S2 Lost its beauty, slimness(figure ) and sex appeal
3) Feels Bulky in pocket

But thankfully it does what its meant for. Here are the battery life stats so far-
First charge took almost 6 hours to reach 100% but I let it charge for 10-11 hours.
~37 hours backup
-3 hours 38 mins SOT
- 30-40% screen brightness
Wifi on for ~15 hours
was at 53% after 26 hours, and the drop after that was pretty fast.

2nd charge - took close to 4.5 hours on usb charging
~ 27 hours
- 30-40% screen brightness
~3 hours SOT
-with heavy usage, backing up apps/data, restoring/installing lots of apps, backing up rom and flashing rom thrice
- noticed that the drop after 50% status is very fast. (5-7 % per hour)

3rd charge - took approx 5.5 hours to charge fully (with me installing multiple apps and stuff)
- 43 hours backup
- 30-40% screen brightness
- ~2.5 hrs SOT
- wifi on for ~20 hours, ~40 mins calls, flashing kernels and normal messaging.

Baseline - Apart from the compromise I made on looks of the phone, I am really happy with the battery backup. I could get that kinda backup time only while keeping the phone in standby and very less SOT. I found that the upper part of phone heats up (as usual when involved with heavy activities) but the battery was totally cool. So my fears of it exploding are subsiding with time

Few pics of the phone, battery and backpanel are attached.

P.S. Will be updating the battery stats for next few charges.

I am thinking of buying a similar battery but i dont know because the s2 will become heavier and will lose its slim shape.
Anyway, does the extended battery make big difference to your battery life?

With my 1650 mAh battery I could get 3+ hours SOT but then it wont last for 24 hours. With the new battery I am getting 1.5+ times more battery life than it was previously. The imp thing would be to see for how long i get it (as it is Chinese)

and yeah, with this battery - bye bye slimness and lightness for S2.

Massive! I was tempted too, but I'll resort to some external battery pack; I can't stand seeing the sII with this big fat back

I was a lil demotivated too before buying it but now this big-assed-s2 feels like a new phone to me. To top that, battery backup is pretty much better than the stock. Its like atleast 1.5-2 times more than stock which matters to me a lot.
I am happy with it
