Yes, Energizer 18K Pop has 18,000mAh Battery.
it's like power Bank, it takes too much time to charge full charge.
I think any smartphone has 5000mAh battery back-up is the best.
one of my colleague has the same problem in HTC Phone, She tried to repair herself but can't fix, then she visited to a Repair shop, They just rebooted his phone.
Alcatel Fierce One has 1800 mAh battery. and today's applications are used more battery. I don't think a new battery can more effective. if your battery is not working 8hr then you can replace.
