subject: Why Yourcell phone Battery Might Be Dying [print this page] Fact is, cell phone technology has grown rapidly over the past 4-5 years, but battery technology just hasn't kept pace. Cell phones use lithium-ion batteries with a normal lifespan of 2-3 years. They are efficient power sources and often last a couple days when fully charged. dell xps m1330 battery
If we recall 2003, it wasn't uncommon to find cell phones that gave just 1 hr of talktime with a standby time of under 24 hrs, forcing us to recharge every night, overnight. These days, despite all the processing power involved, we can expect the typical Nokia or Sony cell phone to last much longer than that -- Say 4-6 hrs of talktime and 2-3 days of standby time. Now, why do we get a real 50-75% of that? This is why. dell vostro 1520 battery
We must take into consideration that manufacturers test the phone for calling and sms only when it comes to battery life, they do NOT publish the battery life when using many applications. So, battery life is tested only for the basic uses of the phone.
Under "normal" usage circumstances, however, we do a lot more than that. Here are 8 of the things that a cell phone tends to engage in on a real-world basis: acer extensa 5210 battery
1. Bluetooth on most phones having it is almost always on.
2. We've got multiple applications running in the foreground and background - even those we're not using.
3. Emails are being sent and the Internet is being browsed.
4. The brightness of our phone screen is set to high by default.
5. We've got sounds and vibrating alerts on, instead of functional ringtones.
6. For travelers and business users on roaming, the phone is constantly locating a signal -- which eats into precious battery time like no one's business.
7. We tend to overcharge our battery by keeping it plugged in for over 24 hrs, or the opposite -- completely discharge the battery before recharging it again.
8. Lastly (and more commonly), our phone is continually exposed to heat, cold, dust, rain, oil fumes, shocks and vibrations, including accidental drops on a hard floor.
The first 6 consume power while the last 2 can irreversibly damage the cell phone.
Low power is the thing users complain about most, and the more service a phone offers, the more energy is consumed, but as well you stress processor and memory.
The overall performance of our cell phone depends heavily on how efficiently the battery is used in day-to-day scenarios. By cutting down on just a couple of the points above, the battery will last longer -- not just between charges but also over its overall lifespan.
