I bought the Galaxy S4 on thursday the guy in the shop set it up before any charging took place, i got home charged it for around 4 hours i went out got home it was 100% so i unplugged it the battery didnt last long at all would drop 5% in a few minutes with nothing running.... took it back got a new one today... charged it for 6 hours! 13:30 - 19:30 and set everything up after, now at 1:19 its on 1%
-___- Someone tell me how long to charge this phone for to get the best use out of it my friends have the phone and im hearing different times.
I don't think there is any advantage to that at all. It's probably a tiny bit of extra, unnecessary wear, but nothing you'll be able to measure or notice. I don't think there's any need to "calibrate" the battery or charger anymore. It may have been true in the past, but they have a really good idea of what the limits of the battery are when new so you won't get any better performance by running your battery down. It just adds unnecessary, but again, probably not noticeable, wear on the battery.I have been told you run your new battery life to about 10%
Then charge overnight.
That's BS!!... That was to do with the old nickel-based batteries, such as the old analogue Nokia phones and so on. Not the modern smartphones, even tho this site is to do with Android in general. Most, if not - all modern smartphones when brand new, generally have around 40% charged while brand new in the box. For longevity of your batteries, it is always wise to fully charge your new phone on first use. [I have always done this!! I have owned Samsung Galaxy S2, Note, and now Note 3 for the past cpl of mths!!] You know, that if you don't "teach" your rechargeable batteries their full potential by taking them from totally full to totally empty, they'll "forget" part of their capacity. This is an absolute rule and is so true!! Here is a very good article...I have been told you run your new battery life to about 10%
Then charge overnight.
