Long story short, I want to get into the whole apple ecosystem (eventually) and what better way to start it by using an iPhone. However, I don't want to spend almost $800 on a current generation iPhone just to realize that it's not my cup of tea. I got an old hand-me-down iPhone 6 (not 6s) that has seen better days, but the battery is the real killer (has 51% battery capacity according to the "battery" section in the iPhone settings). It shuts down at around 70% battery life or so after using apps like FB or YouTube and drains super fast, so I'm planning to replace it while the $30 battery replacement is still available. My only concern is the battery life even after a new battery is placed; for a phone that is almost 4 years old, I'm concerned that the battery performance will be sub-par at best since we're at ios 11.4 already.
In this case, is it still worth it to replace the battery of an iPhone 6? How good is the battery life of a brand new iPhone 6 (or an old iPhone 6 with a brand new battery) running on ios 11.4? I'm not desperate to get this thing running or anything; I use a different phone as my daily driver. I'm just hoping that this iPhone is still usable (as a daily driver) so it won't go to waste.
