Hello i just got my iPhone 7 Plus
and i want to know how i should charge it in a correct way so that the battery can last longer and not start losing battery juice quickly

Thanks in advance
 
Generally applies to Lithium-based batteries:
- Under any circumstances: never discharge it completely and then keep it discharged for a long time.
- If possible charge with about 1 C, when you need to charge it quick don't surpass 2 C.

ive heard people saying the correct way is to charge it from 30% to 85%
 
That would totally work, although it seems a bit too generous to me.
You are only using 55% of your battery capacity, if you account for implemented battery buffers probably more like 45%. Doesn't harm your battery but isn't necessary either.

Plug it in and charge it when you are worried about not having enough juice.

There's no longer a trick to conditioning batteries.

That is he only realistic answer really. Anything else beyond it might give a bit of improvement here or there, but not really to the level where it would truly be noticeable or at least worthwhile of the efforts spent on dealing with it all.

what about charging overnight?

No problem there. Let's say you start charging at 50%. Maybe an hour later it will reach 100% and stop charging and start draining the battery again. An iPhone looses very little battery in stand by (for me maybe 1-5% overnight). So every time your phone drains to 99% it will top it off to 100 again.

So it's not a constant stream of current getting pumped in all night as some people think. The only valid reason not to charge overnight is fire hazard.

I have set my battery threshold to 25 percent. I plug it when it reaches between 25 ~ 30% so to avoid stress on mobile.
 
I use a clock app on my phone each night so my phone is plugged in every time I go to bed.

Never been an issue with any phone I've used in this manner since May 2008.
 
Anything you do, just don't charge it while you're using the phone especially for heavy tasks (playing games, watching videos on YouTube, etc). My previous experience, i kept on doing this and then the battery had a bulge on it which apparently i had to replace with the new battery
