What's Best For Battery Life?

Charging Over Night,

Leaving it On and Charging in the Morning,

Just Turning it Off and On Again in the Morning?

I wouldn’t charge it overnight because that will shorten the battery’s capacity and life span. Once it reaches 100% take it out.

I charge it my laptop all the time and never take it out because I always have it plugged and never take it anywhere so I don’t care about battery life.

There are a couple practical approaches here. First, you can charge all night, with the caveat that batteries don't like being in a high state of charge for overly long.

 

Second, you can fast charge in the morning (to around 70%-80%) as you're getting ready for the day. So long as heat is under control, this is probably the best option for longevity.

I think Linus' latest video on the topic covers this pretty well. According to that, the best state for batteries is at 50%. So if you would were to keep it at 40-60%, that would be best.
However in the real world, that's not possible. So what I do is I charge it to 60-70% before going to sleep, in the morning I plug it in, and bring it up to 90-100%. So the phone is around 50-75% most of the time.

Doesn't matter kinda.

 

Letting the Plug in at 100% does NOT harm the battery AT ALL.

The Charge elctronics will stop the charge once it reaches 100%, and only let a tiny little bit through, to keep it at 100% (or the Phone itself takes the power directly from the Plug, and battery will neither charge, nor discharge).

For rooted Android phones, use the app Battery Charge Limit and set it to 95%/90%

And then you can safely let it charge overnight. Don't charge to 100% because at high % it is harder on the battery to approach full charge.

The second value of 90% means the app will prevent charging until it drops below 90%

Allowing the battery to naturally discharge that 5% effectively prevents trickle charging which is a culprit of battery deterioration.

 

The app works and I use it on all my phones. I use old unwanted phones as smart wifi adapters which meant they are plugged in all the time. Before I used this app they would eventually have their battery bloat to the point of failure. Doesn't happen any more since the app prevents trickle charging.

Unfortunately there is no alternative that does not require root or for Apple devices.

Kind of crappy that Android doesn't expose this functionality itself. I was hoping to avoid root, though I probably won't have much of a choice pretty soon as my phone sees regular hotspot use.

This makes sense, but does turning it off overnight help? I know it still discharges a bit but my logic is that if the battery being off outweighs the damage done by turning it back on?

As long as you turn it off at 40-60% charge, it's great.
