@rudra  I don't understand, what you said in the first half of your post is exactly what Apple did during 2018.  They created a HUGE marketing campaign supported by a HUGE technological initiative to fix the batteries of all Apple devices that needed fixing.  Right down to training the Apple resellers at their branches and providing them with testing equipment and batteries to fix the phones.  One could make an appointment to see an Apple Reseller to test one's phone and to have it fixed if necessary and all of that was supported by Apple finance (not sure how but I'm sure there were some initiatives for the resellers to do that for Apple).  I'm not so sure it was really to solve the battery problem, but more a big marketing campaign to get support from their existing customers and also get new customers' attention.  

I went through the battery testing campaign, and it was impressive.  Except nothing of the product really changed.  The iffy battery was found to be OK according to Apple's test results, and it was still slow in charging and needed charging much more often than my Samsung phones.   Apple's first motive is always to sell Apple to as many people as they can.  Fixing Apple so it's technologically the best phone always serve the motive for making the buck first.  For example if the tech team tells the marketing team they're not ready yet to launch on 1st of September or any other date, then the marketing team says they better be ready and produce whatever they have on that day.  So short cuts probably have to be taken by the tech team to serve the higher good - which is always the making of a buck - the sales and marketing team.
