I could have replied to any number of posts but I’ll respond to yours.
Battery technology, lithium ion included has not created a rechargeable battery with a life span that extends much beyond 500 cycles with a max of about 1000 cycles.
Logically as you would expect... where a “NEW” iPhone 5 or LG or Samsung or _________ gave (gives) maximum battery life initially that power will fall off by percentage points each month of use until the battery is no longer considered useable.
So... a 2 or 3 year old iPhone (or any other battery powered device) will no longer provide 12/14/18 hours between charges (based on talk time) and will “at some point” need to be charged more often in an increasingly shortened window.
So to the guy with an iPhone 4 complaining about battery life... pay to have the battery replaced or buy a new phone.
And to you with the new LG G2... please brag about battery life a year from now at which point your post will have some intrinsic value.
Pardon me for not explaining that I was comparing my new phone and its battery life to other new phones I have had when they were brand new. I am well aware of battery efficiencies waning during the lifetime of electronic items. As most anyone is who has had more than one computer, iPhone, iPad, Droid, etc.
My iPhone 4s battery was just fine until I upgraded my OS last week. Don't try to tell me my battery degraded 50% overnight, on the very same night that I upgraded my operating system. It is that kind of snarky, lying bullshit that drives people away from Apple products.
If they have lost control of the process, and are now just producing bloatware, they should admit it. Embrace the suck, and try to convince the customer he can't live without it.
