    Scheduled Charging


    Most phones already are capable of predicting the necessary time to charge to 100%, as well as the ability to stop or interrupt the charging process. So why don’t we combine these features?

    Who are the users?
    My proposed feature is targeted mostly towards power-users that use their phone in such a way that the battery is empty right when they go to bed. As far as I know, this is fairly common and a day is a normal time span for a Smartphone battery to last.

    What is the proposed feature?
    I envision an option similar to the “scheduled power on/off”- feature where basically you can state the time you are going to wake up in the morning and plug your phone into the outlet. The software will analyze the battery percentage you have left and will predict how long it will take to charge to 100%. Then, it will initiate the charging process just in time for it to be finished when you wake up. This will conserve the battery as it is not good to charge it overnight. This feature will contribute to users being able to use their phone for a longer time.

    What is the user value?
    As the feature would help conserve the battery, it would enable you to use your phone for a longer time because normally, partly due to charging over night, the batteries’ maximum capacity shrinks over time. By preventing this, phones can “live” longer.

    If there are existing comparable functions in the Smartphone industry, how is your proposed feature superior?
    As far as I know, no one has implemented this kind of a feature before. This is a chance for OnePlus to be the first at something and set a trend.

    Explain the logic behind this feature and how you want it to be implemented
    I would want an option named “scheduled charging” to show up under “utilities”, right under the “scheduled power on/off”-option. When you tap it, there should be a text explaining the feature and underneath this, you should type in the time you wake up.

    You can use a smart wall adapter for this purpose. And you can configure it to turn on at a specific time every day.

    But isn't OnePlus all about making the user experience smoother rather than forcing us to rely on third party apps or, in this case, even hardware extensions?

    The thing is, there is no need for all these. You can just plug in your phone overnight. Your phone has overcharge protection. That said, what is actually bad for your phone is letting it’s battery go below 10%.

    You're right, but overcharge is not the problem. The actual problem is trickle-charging.

    What’s wrong with trickle charging?

    A “trickle charge” attempts to keep it at 100% to compensate for the small bit of charge that your phone just naturally loses on its own. So your phone is constantly being bounced between a full charge and a bit below a full charge. These trickle charges can lead to higher ambient temperatures for your phone, which can reduce capacity over time.

    See, the problem is that the phone will always charge to 100%, stop charging, lose 1%, start charging again and so on and so forth. The reason why this is an issue is that by doing this, you make the battery complete one charging cycle. The amount of cycles that a battery can make is limited and the more cycles it went through, the lower the maximum capacity gets.

    THE REAL thing here should be charging to ~75% and then stopping as charging to 100% drastically lowers the battery Life, the degradation rises exponentially and holding your phone around 50 is the best you could do but thats not possible so 75-80% Charge still is only 20% of the battery degradation compared to charging to 100%.

    This is Bullshit, your phone Battery dosn't have 100.000 cycles that it goes through and then dies and charging from 99% to 100% overnight multiple times dosnt decrease the non Existent Cycle Counter. It is more that it's way Harder to Squeeze more juice into your Battery the fuller it gets, and the more it tries the more your Battery takes damage, think of it like an Car and how you can easily Fit 5 People in it and The sixth goes a bit harder and so one and after 10 People you might have more air space left but you would need much more force to get him in then the ones before. That's why Dash charging works fast to 0-50 but slows down after that.

    Well, thanks for clarifying - I'm not an expert. But either way, charging overnight is not good for your battery, hence why the feature should be implemented.

    there are so many theories with their own explanations. while they may have some truth in them, for the most part you are unlikely to cause any damage by leaving your phone charging overnight. this is also just another theory, but one that is generally more accepted.
