Help Overheating if plugged into charger 24/7

Hi,

I want to use my Googe Nexus 6P as a dedicated remote control for my smart devices. I will be controlling the devices using the Logitech Harmony app which is linked to a Logitech Harmony Ultimate Hub. If I was to select the developer option for "stay awake" (screen will never sleep while charging) and if I keep the phone plugged into the charged 24/7, would the phone experience any overheating issues?

Regards,
Arun
 
You can use a programable outlet timer to alternate the phone's charging/discharging. For example you can program the timer to turn on for 4 hour then off for 6 hours and so on... The time for your phone to charge and discharge.
 
If you go for a timer, remember to buy a model with backup battery so you don't have to start from scratch after a short power outage.
 
If I was to use a programmable outlet timer, how could I keep the screen switched on during the periods when the phone is not charging? The "stay awake" function is only for when the phone is being charged. Are there any settings to keep the screen on all the time even whilst the phone is not charging?
 
Leaving your phone plugged in all the time will not overheat it. This isn't good for the battery's longevity but since the phone apparently isn't going taken out the mobility aspect isn't a factor anyway. There's a lot of inherent over-charging protection when it comes to the interactions between a battery and a charger so when the battery level is at 100% the charger stops providing current. Leaving a charger plugged in will only result in the constant cycle where the battery will eventually drain a bit so when it drops to a certain level the charger kicks in until the battery is 'topped off' again, and then the cycle just keeps repeating. Any assumptions that a charger will just keep pushing power into a battery until it melts or whatever isn't based on factual information. The BatteryUniversity site has some good, and current (gets updated regularly) info on this:

Also as a side note, I think your Nexus 6P has a Lithium-Polymer battery (as opposed to a Lithium-Ion)

Nexus 6P has a thermal engine buikt in but due to hiw tge kernel is configured the thermalcengime Cire cintrol is on but the VDD Restriction etc is disabled by default you shoukd root your device and installed Kernel Auditor to enable these options
 
Just adding a fact, there are a lot of restaurants in my town where you get an Android tablet on every table to order the foods by yourself. Those tablets are always turned on during business hours (generally from 0800 to 2100).

So leaving a device plugged in is not a big deal, but it's recommended to turn it off a couple of hours each day, ideally at night (can be automatically done using a programable timer).

Ok. It appears according to this that leaving the phone plugged into the charger 24/7 will not cause overheating issues. However, could leaving the phone screen switched on (at minimum brightness level) and an application open 24/7 have any potential overheating issues?

I use my Nexus 6P alot more then 12 hours a day and never had overheating issues, however i can say it does overheat when in hot tempature conditions
 
Ok. Problem solved.

I bought a tp-link smart wi-fi plug as Ivt suggested and alternate it between two hours off and four hours on every 6 hours, just in case leaving the phone plugged into the charger 24-7 could potentially cause any damage.

Also, with regards to keeping the phone display switched on all the time, I downloaded an app that wakes the screen when I double-tap it, and since the harmony app is open when the phone auto-sleeps after 1 minute, when I unlock the phone by double-tapping the harmony app remains open. This way I could avoid the screen burn-in issue as MoodyBlues suggested and I can use the screen on full brightness and not worry about the phone overheating if I was to leave the screen on 24-7.

Thanks a lot of your help.

Couldn't have solved it without you.
