I purchased this to replace my original Sony BA700 for my Sony Xperia Pro phone. The stock Sony BA700 battery (1300mAh) gives me approximately 10hrs on battery life. With the stock battery, in order to have my battery last till I get home at 6pm, I can only unplug the charger at home 8am, and then leave the house for work.
The new Ecell 2430mAh battery gives me approximately 12hrs on the phone. I can now unplug the phone when my daily wake up alarm goes off at 6.00am and still have some charge when I reach home at 6pm.
I love this battery and highly recommend it to anyone who wants a peace of mind for their phones during the day.
For battery usage reference, throughout the day, on my Android phone, I switch on WiFi and enable Data Transfer mode all-day long. I read emails, facebook and twitter almost once every hour.
When I have the chance, I let the phone dies (complete discharge) at home, and then charge it to full capacity. I believe that complete discharging would keep the battery healthy and prolong it's life.
In terms of safety, there's no problems with my phone or battery until current use. I strongly believe that this battery is safe to use.
In terms of shipping, my item arrived in Malaysia on-time, which approximately 2-weeks from the estimated delivery time.
At the time of writing, I believe, I've been using this battery for approximately three months.
Hope this information helps to those thinking about buying it. My conclusion: Go get it.
