Batteries for Cell & Smart Phones, Tablets and More
On this page you find information about batteries for cell phone, smartphone and other wireless devices.
Really cold weather and batteries in mobile devices.
Yes, it's wintertime and that means to take extra care for your battery-carrying mobile device. In particular when it's quite cold, really freezing weather so to say.
Because under those kind of circumstances the battery might fail delivering energy to your device. And that is quite ennoying when you want to use it at that time, and your phone shuts off all of a sudden.
The remedy to take your device in an area with a normal temperature. It then will come to live again.
Apple indicates that it is better not to use their iPhones when temperatures are below 32 degrees or beyond 95 degrees Fahrenheit.
A well-rated and popular battery for Samsung devices is the EB484659VA 1500mAh spare replacement Li-ion battery.

Here's a bit of basic information about battery differences.
Most analog phone batteries only provide a couple hours of talk time and 24 hours of standby time. Digital cell phone batteries / batterys such as nickel cadmium (LiON) are capable of lasting much longer between recharges.
Digital signals require significantly less power to transmit than analog phones .
Cell Phone Battery Types
To find out what type of cell phone batteries you have, switch off your cellphone and remove the battery. The battery type is printed on the battery label.
Examples of popular smartphone batteries and chargers are:

Or Anker Astro 3E 10000mAh Dual USB Backup External Battery Pack Portable Power Pack Charger, See Here on Amazon for best pricing!
Let's take a look at the three battery technologies for cellphones. <
Nickel-Cadmium (NiCd) Cell Phone Batteries
Although newer high-performance phones have rendered it nearly obsolete, these nickel cadmium battries are still commonly used in many consumer electronics for its durability and low cost. Some pros and cons:
- Compatibility. Older phones are more likely to require NiCd. It generates relatively little heat, and many older phones cannot withstand the more heat-intensive NiMH or LiON batteries.
- Durability. It charges quickly and handles well under extreme temperatures.
- Shorter Lifecycle. It provides relatively less power per charge, so you must recharge it more often. You can usually recharge it over 700 times before reaching the end of its useful life.
- Memory Effect. If you recharge a NiCd battery before it has completely discharged (run out of energy), it will "forget" that it has all of that extra capacity. So it will only partially recharge, leaving you with a weaker battery.
Nickel-Metal Hydride (NiMH) Cell Phone Batteries
The next battery generation to follow NiCd.
NiMH costs more but offers several improvements:
- Longer Lifecycle. A NiMH battery will last around 25-30% longer on each charge than a NiCd of similar size. Life expectancy, in terms of recharge cycles, is comparable to NiCd.
- Lightweight. Lighter than NiCd, NiMH batteries can weigh under 3 ounces.
- Less Memory Effect. Although still a problem, it occurs to a much lesser extent than with NiCd. See "Memory Effect" in the NiCd section for more details.
- No Toxic Materials. Like everything else, when a battery reaches the end of its useful life the disposed remains end up back in the environment. NiMH does not contain the kind of toxic materials found in some batteries, and is therefore far more environmentally friendly.
Lithium-Ion (LiON) Cell Phone Batteries
As the newest battery technology, LiON is both superior to and more expensive than NiMH. It has some major advantages:
- Even Longer Lifecycle. The newest Internet-ready cell telephones use a lot of muscle and they need a cellphone battery that can get the job done. LiON lasts up to twice as long per charge as NiMH and lasts approximately 400 charges.
- Lightest. The latest ultra lightweight cell telephones use LiON batteries which tend to weigh 30% less than NiMH.
- No Memory Effect. You can recharge it at any time, even if it has not fully discharged, without losing performance. As a precaution though, you may want to fully discharge and then recharge your LiON battery from time to time. When it comes to precision equipment, better safe than sorry.
- No Toxic Materials. Like NiMH, LiON batteries are relatively environmentally friendly.
