What is the function of the on/off switch. to save battery or to have on when charging and off when charging at the wall oulet?

On a cell phone it is to extend battery life when the phone is not required. Some phones will still retain some functions eg alarm clock, even when off. You don't need to turn the phone off when charging, but it will charge up faster if you do.

My htc one mini isn't turning on, But it comes up with the battery sign? What's wrong with the phone?

It sounds like you need to charge it up.the charge icon usually means there is insuffient power to switch may be the battery isn't charging properly I.e. The charger is faulty...the charging point is faulty...or the battery is no longer holding a charge.sometimes if you charge abroad or on say a ship where the amp of the circuit is less the 500 mah the charging behavior changes and it takes a few attempts to get it to behave normally.
another thing you might try is change the charger to a more powerful one just to give it a boost.i.e. Instead of using the normal 5 volt 1amp try a charger with 5volt 2 amps.once the battery reaches at least 5%. It should start up.fully charge and then try to get into the habit of running phone down to 20% and up to 80. % instead of continuously charging each day when the phone is still holding a healthy percentage?only once in while should you run below 5% and then charge to 100% .incidentally most batteries start to lose their stamina after 500 plus charges.

My htc 8s wont charge

Do not do a hard reset,you don't need to. Hold the power button down for twenty seconds and the phone will reboot itself.

My on/off switch doesn't work

We all have the same problem. Our phones too run as long as the battery is charged. Why dont you charge the battery? As regards the on/off switch, get it repaire from Nokia Care or whoever you feel will do a good job.

Charging problem

I had this same problem, it's really irritating. Not exactly a full solution, but if you leave your phone connected to the usb for around 10 - 15 mins then disconnect it, remove and replace the battery and turn it on, it should have enough power to boot up, the just reinsert the usb and it should charge.

Battery charge is finished very soon without even using it( in about 5 hours)

The proper way of charging the battery on your phone is by waiting for your phone to indicate that it's running out of powe but not completelyr, if you frequently charge your phone even if it's not yet necessary(battery life indicator show half-way) the ability of the battery to store power will deminished hence the battery life is shorter. Last resort would be trying another battery unit to test if it's your battery of your phone that's causing the unsual battery drain.

Or you can try the following steps on conserving your phones battery life;

  • Turn off your Infrared and BlueTooth when not in use. Even when they are not in use, they do keep drawing power looking for signals.
  • Switch off the vibration alerts. Vibration causes a lot of power usage thereby making battery drain fast.
  • Re-adjust your screen brightness to around 50%. Screen power is another silent killer.
  • Usually, presetted Backlight durations are of pretty high order, this can be readjusted to get more from your battery. Try reducing the Backlight duration.
  • Often we don’t understand that playing games requires Light, Sounds and Shakes. This in turn leads to tripling of battery drainage.
  • Lower Ringing and other message sounds. This too helps saving a lot of battery.
  • Finally, do charge your battery before it gets drained fully. This enhances battery life.
