I know that all batteries degrade at some point it ' d be nice if I can find a way for it to degrade later rather than sooner , or not as quickly . Even though I paid only $ 600 for this thing , this is supposed to be a premium device and I ' d like to keep it going strong as long as I can . I know you don ' t feel the way I do , but I ' ve always found selling stuff to be a giant hassle , compared to just keeping the device for yourself for a solid three or four years . The article you linked implies that the only real way to keep a battery healthy , outside of extreme temperatures and improper longterm storage , is to make sure it lasts longer per charge , which I ' ve made a lot of tweaks for already . So . if that ' s really all you can do , alrighty .
