All the comments here are valid - we have been reworking a lot of the internal scheduling code. Hopefully over the next couple months we'll be able to have better fine-tuning of controls so users can set what % of CPU is used for mining.

Good idea specially for smartphones.

The best way to help your cpu is simply to maintain a constant heat so that its physical state doesn't change too much. If the heat that is generated by the processor is too high, the best way to deal with that is to go into your power management scheme in your settings/control panel. There is an option under advanced settings to lower the maximum and minimum processor states. Another option is to just stick a cooling pad under your laptop, or leave a bit of space around your pc case. For me the best option is to probably stop resting hot coffee cups on it. Having looked at system resource use at the moment it seems that cpu usage is at only about half of maximum for this app.

No really good idea. Heating up and cooling is poison for boards. The device is even broken faster.

ive turn a lot of background apps of from running ing the background ,my fan on my laptop seems to be less active thanks andi
