Extended Battery Review for Samsung Galaxy SII
Good day.
After reading the article “ Experience using a 3600 mAh battery for the HTC Sensation smartphone, ” I also wanted to buy a high-capacity battery for my Samsung Galaxy SII.
I purchased it in the same store as the author of the article. Here it is . The purchase price at the time of this writing was $ 98.95. For this money you will get an advanced 3200 mAh battery for the Galaxy S2 and two back covers. Plain, and with stand, white or black to choose from. It is rather strange that they turned out to be two, since it is not written anywhere on the site, only from the photographs of the goods one could guess what awaits us. It took three weeks to wait for the delivery of the parcel to Minsk from Hong Kong.

Just want to note that the original of this text was not written by the author of this post (that is, I, HeavyRazzer ), but by the respected akill . Unfortunately, he does not have the right to write articles on Habré. From me only advice on the order of the battery, the general plan of the article, minor final edits.
And so she came. In standard packaging with pimply polyethylene inside.

Directly in the package were found two covers, one battery + instructions for the initial calibration of the battery in English.

Galaxy SII can work on such a battery for about 4.5 days with an average load: an hour of music, an hour of surfing over Wi-Fi, 10 minutes of calls per day.
Experimentally, it was found that a full battery charge is enough for:
28 hours of continuous music playback in headphones (14 hours standard battery)
13 hours of continuous video playback, 720x384 resolution, sound output to the headphones (8 hours standard)
4.5 hours of games (2.5 hours with standard).

There are two covers included. One with a retractable iron stand, the second - the usual, no frills. The outer side of the covers is rough, no gloss, which is very pleasing. Fingerprint covers do not save. Both are made of plastic. The holes for the camera are great in collecting dust. New covers do not affect the reception of cellular signals or Wi-Fi.

There were no problems with closing the lids, but with the inverse procedure there were some minor problems. To open it, you need to make a little more effort than to remove the standard cover. But then you get used to it, and problems no longer arise. The thickness of the phone with a new cover is 1.5 cm.

It was easy for me to get used to the increased size of the smartphone, after a week of operation in general you stop noticing that something has changed. Wearing is also no problem, the Galaxy S2 still fits in a pocket of jeans or a jacket. You do not feel any discomfort. In his hand, the phone is also excellent, that with a normal, that with a reinforced cover.
Appearance of course suffers. When I used to see my SII thin and stylish, but here such a hump sticks out ... But you have to sacrifice something for the sake of increased autonomy.
As for the expediency of purchasing a high-capacity battery, then everything is individual. If you are often away from sockets, then of course I recommend to buy. If it is not difficult for you to recharge your device once a day / two, and you rarely go somewhere - it is not worth it.
Testing was conducted on the Samsung Galaxy SII with Android 4.0.3. Omega ICSrus firmware 15.0.1.
