For long term battery health I wouldn't recommend keeping it plugged in for long periods of time. People say today's batteries have protective circuits that prevent overcharging, but I don't really trust this. So I simply unplug it as soon as it is fully charged.

As for actual better battery life, turn off everything you don't need - GPS, Bluetooth, Wi-Fi, Mobile Data etc. This phone should give you an average of 6 hours SOT. To obtain more you will probably need a custom kernel, but even then the results may vary.

Yeah it has protection circuit to protect overcharging. Lithium based batteries can always take charge, and might self-combust. (ok , worst case. basically, lithium can't get in contact with water. RH in air is just enough to start the self combustion reaction). Nowadays, Li-ion or Li-Po are well made, and this is less problematic.

This as been said, it doesn't mean that this circuit won't trigger the battery every 0.XXX% drop, which is not good, so yeah, until someone do electric reading test on the op5, I won't suggest to let the device plugged in when full.

Simple rules for lithuim based batteries :
- time will kill the battery, even if it's brand new sealed. (normal chemical reaction). Nothing we can do here, limit extreme temperatures, not too cold not too hot.
- heat will decrease battery life and capacity. This mean, dash charging will decrease life. So, 1.2A to 2.0 [email protected] charger is more appropriate. Even if dash tech will regulate the charge, you still have a time that it will optimize to max power, so more heat.
- Polarity direction changes will decrease life/capacity. This mean, do not charge it if you don't need to.
- do not wait to drain it at 0%, I don't know what is the security factor from OnePLus. A single lithium based batterie under 2.60-2.75V, will mostlikely be dead , or will loose more than 50% of his capacity.


Some lithium based battery will perform better, but to keep low price, do not worry, oneplus use standard li-po.

When the phone is plugged, it doesn't use the battery anymore, therefore the battery is not drained. Once it reaches 100%, it just stays at 100% until you unplug it.

Some says that leaving the charger plugged is not ecological, because it still uses energy even if it doesn't charge anything, but in reality it hardly use energy. I don't remember the numbers, but it is really insignificant.

In the end, there are a lot of superstitions concerning charging and battery life, most coming from old habits and false/outdated information spreading through the internet. The only things very true is that you should avoid letting your battery going to 0%, and don't let your battery overheat, and that's all. Charge when you please, as long as you please, and avoid using low-cost chargers or batteries as some can be dangerous.

I used my Xiaomi Mi3 for 3 years, letting it plugged every night with a QuickCharge charger, and it could still handle a whole day when I finally sold it.
