1. Turn off your Bluetooth – Bluetooth is the most power hungry application; turn it off when you don’t use it

2. Disable sounds and vibrating alert – you don’t really need keypad tones to be on, do you? What about vibrating? It is surely useful on the meetings or in a cinema but most of time you’ll do just fine without it; I usually set up a vibrating profile to be used in places like cinema or theatre and in all other profiles I have vibrating turned off

3. Brightness – lower the brightness of your screen; not too low, otherwise you’ll destroy your vision
4. Setting the Power saver time - out and the Light time-out to the low values will help too (you’ll find them in the display settings)

5. If you are not using an application switch it off – you’ll get a list of all active applications by long pressing the menu button; this is a general rule that can be applied to any device

6. Games – it’s fun to play games on your way to school but they are power-hungry beasts; I can’t tell you not to play games but think about your battery when you are playing

7. Turn off your phone when you don’t use it – I know that for many of you this is not an option and I’m not sure if turning it off and on is even good for your battery but I heard this tip from so many people that I just had to mention it

Battery Myths

More volts and amps in the battery means the power tool is stronger and better.
False, actually the motor, transmission and other components that product the power also have a great effect on the tools performance. The quality of the magnets in the motor, metal gears, the chuck that transfer to the bit. Basically it is everything from the battery to the blade or bit, how efficient can it transfer the power.

A charger is a charger
Actually some chargers keep charging even when the battery is fully charged. These causes excess heat build up and decrease your battery life. Most professional power tool battery chargers will shut off. This means once the battery is fully charged, the charger will not try to push current through the batteries to charge it.

Batteries have a memory
This is false, well it use to be true. Back in the 80’s when battery technology was just getting off, a battery did have memory. No-a-days with new technology manufactures have developed batteries with any memory. So currently this is a myth. Draining a battery all the way will actually cause more harm to the battery than good. When you drain a battery all the way, you can actually damage cells and they will no longer hold a charge, therefore you might only be using 11 cells instead of all 12 cells which lower your power and battery life. The best gauge to recharge your battery is to charge the battery when it can no longer function for the job. If the saw starts to die when cutting, then it is time to charge it.

Keep Batteries in the freezer
Sound goofy, but I have seen contractors bring a cooler with ice packs to the jobsites. This will not help your power tool batteries; I am not sure about your camera batteries or other smaller batteries. Actually the cold can hurt your batteries if your try to charge them. NiCad are very durable batteries and will work in all most any environment. If it is too cold for you to work outside then just bring your batteries in with you and the batteries will be fine.

Batteries can be rebuild
Some people say yes and some no. I have read a lot about this and still get both answers. The best thing to do is take them to a store and recycle them. Battery prices are coming down in price. If someone rebuilds the battery, who know if they did a good job or used recycled cells. Best advice is to spend a couple of extra bucks and buy the new factory batteries.

Do not completely drain the battery
Do not completely drain the battery, they do not have memory. Charge the battery when it no longer performs its duty to its fullest capacity.
