So here it is, a cheap extended battery for the Galaxy Note 2, costed about 10 USD on eBay. First I noticed it didn’t really extend the battery life, tried some calibration stuff, but no. Not really extended. But I left it on the Galaxy Note 2, thought it would settle or something.
But a few days ago, the battery started to behave badly, discharged quickly. After about a month of use, it went from not really extending battery life, to reducing battery life… 🙁
Its time for a real extended battery, like the Mugen, I had that on my Galaxy Note 1, and although the case was bad, the battery was great.
Cheap batteries from eBay. Never again.
