It's hard to get your battery to last a long time. Most phones in this day and age are only expected to have roughly 4-5 hours of talk time. And that counts all the extra stuff we like to do on our phones. With most phones acting as cameras, music players, GPS systems and portable internet, it's no surprise the battery life of our phones are pure junk. Thus, I'd like to give you a few tips on how to get the most out of your battery.
1. Turn off Bluetooth
The Bluetooth radio can contribute to a quickly draining battery, so whenever you are not using your Bluetooth device, turn off bluetooth power in the settings menu. Some phones will allow you to set up a shortcut to do this much faster.
2. Lower Screen Brightness
Don't have the screen on its brightest setting, but don't have it on its lowest either. There is rumor that having it constantly on lowest setting will cause you to strain your vision.
3. Decrease backlight time
Similar to screen brightness, whenever the backlight is on it is using up much-needed battery power. Best thing to do is to have it turn off faster when the phone is idle.
4. Turn off 3G or dual mode
The chips in UMTS or HSPA phones are HUGE drainers of your battery. IMO there are a couple very good reasons to turn off 3G if your phone gives you that option. First, if you never use internet, save your battery. Second, turning 3G off will reduce the amount of dropped calls that could occur when going from a 3G area to EDGE. On my phone I find that there may only be one bar of 3G but full bars of GSM strength. Still, since the phone is set up to look for 3G first it doesn't bother to see how good the reception really is, thus causing dropped calls.
5. Stay in areas of good reception
While it may sound odd for saving battery life, this is actually very important. When your phone is in areas of little or no reception, the phone is constantly searching for a better signal. The act of actively searching for a new signal quickly drains your battery.
6. Recharge when 1/3 full
About 90% of the sites I researched considered this a great way to lengthen the overall lifetime of your battery. Generally it is bad to completely discharge the battery (let it totally die) every single time before you charge it again.
According to Asia's Cnet.com:
"A lithium battery can be charged whenever it needs it. Full discharges are not needed--indeed, they are not advisable. Instead, let the battery run down to around a third of its capacity and charge it on a regular basis rather than running the battery completely flat.
If your phone is not displaying the correct amount of energy left in your battery, then let it run completely flat and this should solve the problem."
7. Turn off phone when not needed
Explanation not necessary; however this isn't possible for everyone as some people are on call for business.
8. Keep battery cool, keep out of sun
Lithium batteries are built with protection from overheating, so charging the phone overnight or for 2 days doesn't damage your battery. If, however, it is overcharged for up to a week, the battery will heat up. Overheating will cause permanent damage to your battery. So, don't leave it on the charger and don't keep it out in the sun.
9. No more vibrator
The vibration mechanism on your phone takes quite a bit of power. Keep it on there only when absolutely necessary. Like meetings or quiet shindigs.
10. Lower ring volume and keypad sounds
Similarly, ringtone volume and the "beep-beep" sounds every time you press a button are power users.
11. Take off screensavers and moving wallpaper
This one was a bit of a surprise to me. But, alas, the movements do use up power.
12. Packet data access "only when needed"
When packet data access, typically found in the settings menu under "connectivity" or "network", are turned to Always Online, it means the phones are constantly searching for internet and making sure a connection is enabled. While this doesn't charge your bill for internet usage, it does strain your battery life.
13. Fully discharge battery once every 30 charges
Related to #6, optimal battery life is achieved when for 29 charge cycles you begin the charge when the battery is only 1/3 full, and on the 30th charge you let the battery die completely before charging. Repeat every 30 cycles.
According to batteryuniversity.com:
Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem. Letting the battery run down to the cut-off point in the equipment will do this. If ignored, the fuel gauge will become increasingly less accurate.
14. Turn off active applications
The more multi-tasking you do on your phone, the faster your battery will reach Empty.
15. Clean the battery contacts
Many websites advocate the practice of occasionally cleaning the contacts of your battery with a cotton swab and rubbing alcohol. This maximizes efficiency of energy transfer from your battery to your phone.
