They come anywhere from DOA, to about 3/4 original capacity (at best), usually ~50-60%, and generally a much shorter life-span. IOW, they are mostly crap, but cheap crap.
I'm 100% not surprised but I do need a new battery for my Nexus phone. Do you know of any sources of quality replacement batteries? I was planning to go the DIY route but I would pay to have it done if there are good batteries to be had somewhere.
Buy from a vendor who publishes the Ahr capacity. Return it if it fails to live up to the advert.
MOST of them publish the Ahr (capacity), or at least it's printed obviously on the cell.
Hint - if the capacity listed is more than the original......don't bother. The more the claim = the bigger the lie.
I wish I knew where to reliably get good replacement cells. Sometimes, for a fairly high price, you can get a true original from the manufacturer. OTOH, it could be old.
Even if it claims to be an original battery, if it's 1/4 the price, it's probably not. Sometimes you can remove the wrapping and see what's really underneath.
FWIW, I recently bought a couple off eBay that LOOKED original, and claimed to be original. When received I could not tell the difference from the original in the packaging or the battery. When tested they were ~ 60%. Sent the vendor the picture proof from the test equipment and they admitted they were original, but likely very old stock, as in VERY old. Got a refund and did not need to return. I indicated in the letter that I considered them defective and would not mail them back anyway.
The trouble is PROVING they are not up to capacity. The vast majority of users simply do not have the knowledge or the tools. The anecdotal reviews you get on eBay or Amazon, etc., are pretty much worthless.
