    And BTW... Any chargers work. But avoid cheap no name stuff. Could be harmful both to the phone and yourself.
    Some effort has been taken into account to counteract the problems with quick charging. But still slower charging could prolong life.
    The other problem is if something happens and your charging port turns into a piece of charcoal (or worse). Depending on how Oneplus handle this it could be a problem if the damage happened with a third party charger.

    Thanks for your tips! Are your tips based on personal experience, or found from some specific article or something?

    A little bit of both. A bit of a tech nerd and read a lot. Work in a tech/electronics oriented area too.

    Right now, it's better to charge to 100% overnight our Android phones to have a better battery life.

    Why is it better to charge to 100% overnight? Currently I charge right before I start my day. I wake up, start charging, get myself ready, get breakfast, etc... By the time I'm ready to leave to work it went from 50% to 100% in about 40 minutes. Then the same next day. Would it be better to charge overnight?

    From a technical point of view, batteries should be charged between 20-80% for better battery life. But, for Android in particular, the system does some optimizations only when battery is 100% charged, with device idle, and stationary (that's why I said charging overnight). If this optimizations are not completed, you will experience some battery drain which I think it's worst than charging your battery above 80% (which in fact it's not dangerous). I am not sure if this optimizations should be done only when you install an OTA, or whenever you install/update single apps, so some clarification could be welcome.

    By the way, what you shouldn't do is let your device reach very low battery levels. NEVER let your device to shutdown by reaching 0% battery. Besides, battery calibration is a myth.

    As far as I can tell there are no reasons to do a full charge every night (atleast I have never seen any facts supporting that).
    Always avoiding it is a bad idea as you say.

    If you are posting this review then it must be true.
    how many apps running in background, your screen brightness, which carrier sim you are using these all factors come in picture for battery draining.

    and OP7 has 4A charger so definitely your mobile and battery will get heated while charging.

    Yes, I don't know if that optimization should happens all days (because of update apps) or only from time to time (because of OTAs). I think it's the latest, but I am not sure about that.

    This is not the reason, but I will give you a real case: about 4 years ago, my brother changed his laptop with a new one and stored the older one for 2 months with 0 almost % battery remaining. Then, he give it to me and the battery was dead FOREVER. It never recovered, no matter what you do.

    If I remember, battery degrades too way fast with that low voltages, you can read this article (and others from the same webpage):

    Fully discharged there is some kind of chemical reaction that shortens the battery life time drastically. While discharging it completely is not a catastrophy, if it's charged within a reasonable time, its unessesary wear and will shorten the life time much more than partial charges. The laptop is a good example of bad storage level.

    So you are saying that the battery draining issue will resolve after 4 full cycle??

    I'm merely saying a phone needs a running in period to give its full capacities.
    However, depending on the apps you're using, the quality of your network, some settings, among other things, results will of course be widely different from one to another, or from one day to the following one.

    Hi all look my Battery Cappacity after 5 years using on my Oneplus One
    Many times fully discharge, same for full charge.
    However, I charge when it is around 20/30% for 100%

    Don't worry about batery lifetime :)
    This is a 5 year battery lmao :D
