    So in these summer months, I usually find myself in bed using my phone for several hours straight without ever unplugging my phone. I leave my nexus 4 plugged in at night to 100%, and then use it while its plugged in throughout the day until I have to go somewhere or have a phone call. So is it bad to use my phone while it's plugged in? And if so, how bad?

    A Li-ion battery needs to be regularly cycle through charges to hold their capacity for as long as possible. If you always keep the battery at 100%, then youll slowly begin to notice that the battery wont last as long away from the outlet. Leaving it charged overnight and then using it during the day seems to be the most practical and safe way to go about it.

    Heat may be a concern. The single worst thing you can do to a Li-ion battery is keep it at 100% charge and exposed to high temperatures. It will compromise both the lifespan and capacity. Eg, if you play a graphics intensive game while keeping the device plugged in at 100% charge.

    But dont panic. Your battery is not going to suddenly die overnight on you. It takes prolonged use under these stressful conditions for your battery to have any noticeable effect. Nowadays, batteries seem to be able to take quite a bit of punishment. And if youre going to replace your phone in a year or so anyway, this may not even be a concern.
