Replacement Battery for Samsung Galaxy SIII - 2100 MAH

One of the great things about the Samsung Galaxy S3 is that you can replace the battery. This is a great feature because after enough charge cycles, Lithium ion batteries will degrade and be incapable of retaining the full rated charge. Additionally, a spare battery is one of the best ways to extend the daily life of your phone. When the first battery dies down, simply turn off the phone, pop the cover off the back, and swap out the battery.

This is an exact replacement battery for the Samsung Galaxy S3, rated at 3.7 VDC with 2100mAh of storage capacity.

Note that this battery lacks the internal antenna of the Samsung OEM battery and therefore does not support the NFC (Near Field Communications) feature.

Coming soon is a charging cradle for the Galaxy S3, which can charge the phone with or without an installed phone case and which has a slot for charging this, and the original Samsung, battery!

No complaints 8 months

Pros: cheap replacement, good battery life

Cons: no NFC

It's worked well for the 8 months I've had it. I don't use NFC (Near Field Communication) so not having that feature wasn't a big deal.

Pros: Good when new

Cons: dies quickly

This battery did fine when it was new. Now it is 14 months old and the battery drains from 100% to critically low in 2 hours.

A-OK This Battery

Pros: Reasonable priced. solved the issue.

Cons: None so far

My GS3, a hand me down from the Mrs, was loosing power. It is 2yrs old. After switching off a lot of silly power sucking apps, it still appeared to degrade faster than it s/b. Replaced the battery and it appears better. Now thinking of buying the separate charger to maintain the old battery as a b/u, then again (nah). Shopped O/L and considered all out there. May obtain it less expensive elsewhere, but one should buy from a known source (in case of warranty needs or other) - MonoPrice is reasonable.
