About six months ago, I accidentally dropped my OnePlus One on the driveway where it spent around 8 hours in the burning sun. Of course, while it survived the battery life has never been the same. A replacement battery via a reputable eBay seller did not seem to fix it. It takes about six hours while turned off to reach a full charge, from which I get about 90 minutes worth of use. Under use, it drains faster than it can charge. The charge indicator is wildly inaccurate, with the phone often turning off at 30% capacity or showing 100% when flat. It's extremely frustrating and I'm toying with the idea of getting another OPO, second-hand, and using this one for parts if ever need be.
Is my phone fixable? Did I just get a dud replacement battery?
Yes
