Most of the info here is generic in nature and can also be applied to any other cell phone. So for instance, if someone else in your home has an LG or Nokia or Motorola this would work for them as well. It's a brief history of the battery types used in modern day cell phones.
Now, let us move on to your media. The smart phone is great since you can sync it with a computer and do your thing. Using syncing applications is necessary to move and transfer or update media from desktop to mobile. It is easier right now and you can even customize the content that you want on your phone and make the transfer.
4) Size: terms like slim, ultra slim, main, and extended are commonly used by different vendors and is normally determined by the battery type and capacity. You can offset this by selecting a battery made from lithium stock ion or lithium polymer since they pack more power in the same amount of space.
You have more power to perform work better and faster such as drilling and screwing than the smaller model. Once I used the 18v model I found that I prefer to use it more often because it gives me more power to complete the same task with less effort. At the end of the day it is better and faster, productivity counts.
Another thing to remember is not to store those batteries in the charger as well. This will draw energy away too, and cause your battery to die off sooner than you expect. Keep it away from high heat or extreme coldness. Heat tends to cause damage to your Lithium battery stocks while exposing it to low temperatures over a period of time will draw its charging capacity.
ONickel Metal Hydride (NiMh) - Popular battery about 1-2 years ago. They are lighter than Nickel Cadmium batteries, but heavier than Lithium mines Ontario batteries. These should be cycled once in a while for optimum performance.
Power - this is another important thing which should be considered. You have to know that the more power that the drill has the faster the screw will be bale to go in. hence if your screws go in at a faster rate then you will be able to install your things in less time.
Grooming items are iffy but worth checking out. Shampoo is a decent find as are scrubbies/loofahs. Items like Chapstick and Vaseline can often be found there and my very favorite soap (Yardley oatmeal and almond) is almost always available at the dollar store. Nail files, packages of combs, tooth flossing sticks are of value. Skip the cotton swabs (too flimsy and could be dangerous), make-up (due to lack of regulation), and make-up remover pads (can I just say UGH!?).
