I recently signed up for a Pay As You Go Plan as a backup phone number using my old Verizon S3 which had been sitting around for 3 years without use. I noticed that the battery (original 2100mAh that came with the phone) has bloated a bit and it holds charge for less than a week even without any usage. I purchased an OEM battery from eBay but that lasted even less between charges! I would like a battery that would hold its charge for over a week before requiring a recharge. I would like to avoid having to have two batteries and swap them during the week.
I looked up the suggestions on this site but many of them (Hyperion, Anker, ZeroLemon) are no longer available. I found only the following batteries on eBay.
4800mAh High Capacity Battery + Blue Door For Samsung Galaxy S3 SIII i9300
X Power 4800mAh High Capacity Battery + Blue Door - Samsung Galaxy S3 SIII i9300
EXTENDED 4300mAh Battery + Cover for Samsung Galaxy S3 SIII i9300 T999 L710 i535
4300mAh Extended Battery for Samsung Galaxy S3 Blue Cover Dock Charger
Can anyone recommend any of the above or any other battery? I would like it to last at least a week between recharges. Also, I would prefer not to have to pay more than $20 for it if possible. I am in the U.S.
