The lithium-ion battery
Pioneer work with the lithium battery began in 1912 under G.N. Lewis but it was not until the early 1970s when the first non-rechargeable lithium batteries became commercially available. lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest energy density for weight.
Attempts to develop rechargeable lithium batteries failed due to safety problems. Because of the inherent instability of lithium metal, especially during charging, research shifted to a non-metallic lithium battery using lithium ions. Although slightly lower in energy density than lithium metal, lithium-ion is safe, provided certain precautions are met when charging and discharging. In 1991, the Sony Corporation commercialized the first lithium-ion battery. Other manufacturers followed suit.
The energy density of lithium-ion is typically twice that of the standard nickel-cadmium. There is potential for higher energy densities. The load characteristics are reasonably good and behave similarly to nickel-cadmium in terms of discharge. The high cell voltage of 3.6 volts allows battery pack designs with only one cell. Most of today's mobile phones run on a single cell. A nickel-based pack would require three 1.2-volt cells connected in series.
Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery's life. In addition, the self-discharge is less than half compared to nickel-cadmium, making lithium-ion well suited for modern fuel gauge applications. lithium-ion cells cause little harm when disposed.
Despite its overall advantages, lithium-ion has its drawbacks. It is fragile and requires a protection circuit to maintain safe operation. Built into each pack, the protection circuit limits the peak voltage of each cell during charge and prevents the cell voltage from dropping too low on discharge. In addition, the cell temperature is monitored to prevent temperature extremes. The maximum charge and discharge current on most packs are is limited to between 1C and 2C. With these precautions in place, the possibility of metallic lithium plating occurring due to overcharge is virtually eliminated.
Aging is a concern with most lithium-ion batteries and many manufacturers remain silent about this issue. Some capacity deterioration is noticeable after one year, whether the battery is in use or not. The battery frequently fails after two or three years. It should be noted that other chemistries also have age-related degenerative effects. This is especially true for nickel-metal-hydride if exposed to high ambient temperatures. At the same time, lithium-ion packs are known to have served for five years in some applications.
Manufacturers are constantly improving lithium-ion. New and enhanced chemical combinations are introduced every six months or so. With such rapid progress, it is difficult to assess how well the revised battery will age.
Storage in a cool place slows the aging process of lithium-ion (and other chemistries). Manufacturers recommend storage temperatures of 15°C (59°F). In addition, the battery should be partially charged during storage. The manufacturer recommends a 40% charge.
The most economical lithium-ion battery in terms of cost-to-energy ratio is the cylindrical 18650 (18 is the diameter and 650 the length in mm). This cell is used for mobile computing and other applications that do not demand ultra-thin geometry. If a slim pack is required, the prismatic lithium-ion cell is the best choice. These cells come at a higher cost in terms of stored energy.
Advantages
* High energy density - potential for yet higher capacities.
* Does not need prolonged priming when new. One regular charge is all that's needed.
* Relatively low self-discharge - self-discharge is less than half that of nickel-based batteries.
* Low Maintenance - no periodic discharge is needed; there is no memory.
* Specialty cells can provide very high current to applications such as power tools.
Limitations
* Requires protection circuit to maintain voltage and current within safe limits.
* Subject to aging, even if not in use - storage in a cool place at 40% charge reduces the aging effect.
* Transportation restrictions - shipment of larger quantities may be subject to regulatory control. This restriction does not apply to personal carry-on batteries. (See last section)
* Expensive to manufacture - about 40 percent higher in cost than nickel-cadmium.
* Not fully mature - metals and chemicals are changing on a continuing basis.
The lithium Polymer battery
The lithium-polymer differentiates itself from conventional battery systems in the type of electrolyte used. The original design, dating back to the 1970s, uses a dry solid polymer electrolyte. This electrolyte resembles a plastic-like film that does not conduct electricity but allows ions exchange (electrically charged atoms or groups of atoms). The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.
The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile geometry. With a cell thickness measuring as little as one millimeter (0.039 inches), equipment designers are left to their own imagination in terms of form, shape and size.
Unfortunately, the dry lithium-polymer suffers from poor conductivity. The internal resistance is too high and cannot deliver the current bursts needed to power modern communication devices and spin up the hard drives of mobile computing equipment. Heating the cell to 60°C (140°F) and higher increases the conductivity, a requirement that is unsuitable for portable applications.
To compromise, some gelled electrolyte has been added. The commercial cells use a separator/ electrolyte membrane prepared from the same traditional porous polyethylene or polypropylene separator filled with a polymer, which gels upon filling with the liquid electrolyte. Thus the commercial lithium-ion polymer cells are very similar in chemistry and materials to their liquid electrolyte counter parts.
Lithium-ion-polymer has not caught on as quickly as some analysts had expected. Its superiority to other systems and low manufacturing costs has not been realized. No improvements in capacity gains are achieved - in fact, the capacity is slightly less than that of the standard lithium-ion battery. Lithium-ion-polymer finds its market niche in wafer-thin geometries, such as batteries for credit cards and other such applications.
Advantages
* Very low profile - batteries resembling the profile of a credit card are feasible.
* Flexible form factor - manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
* Lightweight - gelled electrolytes enable simplified packaging by eliminating the metal shell.
* Improved safety - more resistant to overcharge; less chance for electrolyte leakage.
Limitations
* Lower energy density and decreased cycle count compared to lithium-ion.
* Expensive to manufacture.
* No standard sizes. Most cells are produced for high volume consumer markets.
* Higher cost-to-energy ratio than lithium-ion

Samsung Galaxy S III good. but not better than HTC One x
Sg3 have nice feature like:
I tracking, ( HTC one x not have only these feature )
and sg3 have 2100 mAH Lithium- Ion battery but HTC one x have non- removable 1800 mAh Lithium-Ion POlymer battery
Everyone agree Li-Po is better than Li-Ion
I have a Question to every one
What is HTC one x e stand by time on both 3G?
I'm tell my experiences
HTC one x Tegra 3 power saving core is working very perfect on software number 1.29.707.11. This is my current software number. 100% charge ( full charge ) after unplugging 24 hours later 100% on battery
In that time on 3G network ( 24 hours ) 5 miss calls and 2 massage coming on my HTC one x but 100% on battery
And how couldn't identify HTC one x standby time i'm sure HTC one x is standby Up to 100 days on 3G network

Just got my SGS3 yesterday and as I was checking it out , I noticed these small black spots all over my screen when the background is set on a lighter shade of black. It is more visible when viewed from somewhere dark. does anyone else here have this issue with their unit??

HTC Over Samsung:
#Better Built
#Better Looking
#Very good battery Life
#Supar fast
#Easy to hold and use
Over all HTC is a Manly cell phone..The best cell I ever used..
Samsung over HTC:
#better Battery life than HTC
#external Memory facility
#.1" larger screen
If you dont care about looks and want a slightly better battery than Go for samsung..Both are same thing inside..Looks are different..I find no other differences between them..

Now this is what I call ugly. Samsung should hire Sony designers if they don't want to be crushed in a couple of years time! Just look at those new Sony beauties!

i wonder why so many people said this phone was ugly ? For me, it have a smooth curved at the edges and have awesome colour (pebble blue). Samsung is a very BIG hit in nowadays smartphone EXCEPT 'galaxy s2 i9100G' models ! Too many weakness that became major drawbacks that can really draws some people away from being loyal to them (samsung).. Sigh..

Wowowooo..stop it there..well,i think people who post bad things about S3 are just because they are iphone fans,HTC fans etc..n also simply because u guys dont have anymore money to buy an S3 due to your not-as-good S3..man, dont be such a jealousy..posting your bad things about S3 to overcome your regretness for having your current phone is so immature..S3 is the best!!

[deleted post]If anyone paid attention she need to properly replace the battery and did not. Duh.
Either it was done on purpose or honest mistake. either way should be correcte
