{REVIEW} Feipusi 2200mAh battery

---

I ordered this battery off eBay a few weeks ago from HK.

I received the battery a little over a week ago. I immediately charged the battery overnight (at least 12 hour charge) and popped it in the morning. Throughout the day I normally; check my email, a few couple minute phone calls, some web browsing, updating apps through the market, maybe a few videos, and streaming music, and texting pretty much all day.

The battery seemed to be doing just as good as stock. Now after a few charge cycles I believe the battery is doing better.

I can easily get a day out of it on average.

Two days I was sick, so I just text a few times throughout the day and played a few games on the phone.. I got 48 hours out of the battery.

I tried killing the battery one day by watching videos, streaming music and playing games for maybe 6 hours and I still had about 25% left.

For only $6 shipped (it takes about 2 weeks to get from HK) I believe it is a good deal. I keep my stock battery charged as a backup, but so far haven't needed it. When I get home from work I normally still have 30 - 40% left and just throw it on the charger and take it off when I wake up.

It sure is nice not to have to worry about bringing a charger everywhere I go.
I am really surprised that the 450mAh increase made that much difference.
The battery also feels a little lighter.. I don't have a scale to weigh it on, but it does feel slightly lighter

Running R3velation ROM, Overclocked to 1.6GHZ - ondemand (voltage control), Undervolted -50v @ 100,200,400, sync is set at once a day I believe, automatic brightness, using WIFI only when needed, and GPS almost never

Overall... very satisfied.

PS.. my wife got her 3500mAh battery for her captivate. She is easily getting 2 days out of her battery.. I wish I could use it on my Infuse, but I use the Otterbox case... so it will not fit..

I got 2 of these for backup for my wifes and my phone. I use mine all the time. A bit better than the stock battery and for the price was very hard to beat.

Great find, thanks!

On the eBay page, the vendor says:

3. When first get the battery, use it out, charge for 10 hours for the first three times, use it out again, then it only need to charge about 5 hours for normal use.

Did you bother with this, or did you just charge it up and pop it in?

I just popped it in my phone and charged it for 10 to 12 hours

I searched a little on google about batteries and didn't find anything like the Ebay seller said to do.

No problems so far. And still getting a day out of the battery.

This battery need extra back cover or use the ordinary stock back cover?

Thanks for sharing. I had one of the double sized batteries with the extra back, but the battery wore out after only 6 months. I might just go for one of these.

I bought this battery after reading this thread. The battery is slightly more heavier. The battery life seems to last longer when the cell phone is in use but when the phone is on standby the battery dies quicker then the oem battery. Weird.

Those of you needing to know whats going on inside your battery, you need to find "Spare Parts" on the Market/Play Store.
There is a very in-depth app inside called simply "Battery Information"
There you will not only find your % of charge, but battery voltage and temperature, battery health and time since last boot.
Li-Ion batteries are tricky as they require no more than 4.2v, anything more can destroy the battery. Also, the cell is made to operate to no less than 3.0v, any less and the cell will "go to sleep", meaning it won't take a charge unless forced to do so.
Just some FYI, I did my homework on Li-Ion technology and figured I'd share a little...

Looking for a hi-capacity battery
I'll have a look at this....
