This is a common complaint among iphone users. I would take it to an apple store and verify it is discharging properly, but chances are that is just how it's supposed to be. The battery life on these phones is definitely not their main selling point.

How to extend battery time for i phone?


Ensure any unneeded apps are stopped and not running in the background. Some apps such as facebook / twitter / etc may need to be completely uninstalled or logged out to keep them from running.
Turn down the screen brightness, Generally turning the screens brightness down till it can still be easily seen but not overly bright can increase cell phone battery by up to 20%
Shut off wifi / bluetooth / gps when not required. Disable Wifi / bluetooth, and GPS will also increase your phones battery time.

Ensure a full charge, most devices (iphones included) usually require a minimum of 8 solid hours to charge, even when they say full, they are not actually "FULL". Make sure your device gets at least 8 hours of charge time before use, and don't allow the battery to drain all the way before the next charge.

Tip

Tips and Hints on How to Maximise You iPhone 3GS Battery Life


1. Turn Screen Brightness down to less than a half and turn on Auto Brightness. (Settings - Brightness).

2. Turn off Location Services when you are not using a GPS dependant App. If on a long journey using the iPhone's GPS, only turn the App and the service on every so often. GPS based Apps really eat battery life up!
(Settings - General - Location Services - Off).

3. Turn off Fetch Data. With this feature enabled the iPhone will interrogate the internet or your mail account every so often to fetch data, for example, an e-mail. This drains battery life. (Settings - Mail Contacts - Calendars - Fetch New Data - Push Off).

Or if you really want to keep this feature, just follow the same protocol as above , but instead of switching "Push" off, below that, adjust Fetch Data settings, to fetch on a less regular basis ie Hourly as opposed to every 15 mins.

4. On long journeys when all you need is the iPod functionality, turn Flight Mode on.
(Settings - Airplane Mode Off).

5. Remember to run the battery completely flat every so often. I do it around once a month and then fully charge it again.

6. Turn Bluetooth off.
(Settings - General - Bluetooth Off).


7. For those of us who have an iPhone 3GS or updated software on iPhone, switch on the Battery Percentage for better battery monitoring. (Settings - General - Usage - Battery Percentage On).

8. If you are fairly desperate for battery you can turn off the 3G feature of the iPhone. 3G enables higher browsing speed and better call quality. (Settings - General - Network - Enable 3G Off).

9. Turn Wi-Fi off if not in use. The iPhone will use battery searching constantly for Wi-Fi networks. (Settings - Wi-Fi - Wi-Fi Off).

10. Remember, if you really can't manage with the battery life, you can buy iPhone cases which provide extra battery power.

Good Luck

5 year old sedona has low mileage completely dead. What is expected life of battery?


There is no set life expectancy

My wifes lincoln dies at 4 years every time

She had a new cadillac that never made 1 year

I never get less than 8 or 9 years out of a battery
35 years running

If you do not buy the most expensive battery,the one with
the most cca rating,& it has to be completely sealed on top,
not look sealed & have caps that don't come off,then 4 to
5 years is about it

How can I improve my iPhone's battery life?


A recent research conducted on cellphones (smartphones) revealed that most of your battery life is drained by "Internet" and "calls". The more you use your phone for any of these two, the faster your battery drains. Next on the list is "Search for network" which consumes quite a bit of your battery power.
Smaller culprits are WiFi, Bluetooth, Screen brightness, themes, Vibration, etc.
* Reduce screen brightness to minimum
* turn off WiFi/3G/4G when not required (same with Bluetooth)
* if you are out of network area, turn off the mobile network so you cell doesn't keep searching for a network.
* If possible reduce internet usage on your cell phone to improve battery life (ie. if you have a laptop handy, use it!)
* Use a darker wallpaper
* Vibration takes up more battery than ringtones
* use a simple theme
* Dont keep your cell phone charging for long periods (eg. overnight)
* If you plan to buy a new battery, buy a branded authentic one
Hope this helped, thanks for using FixYa!

I had a honeywell hepa air purifier 50250 given to me as a gift with no owners manual! Is there somewhere I can get one? also, there is buttons on the top, one saying check filter and the other saying pre...

The Intelli-Check™ Filter Monitors will indicate replacement of the pre-filter and the

HEPA filter. Depending upon your individual usage (environment and hours used),

you may need to check and replace the filters more or less frequently.

To check Expected Filter Life Usage

When the unit is turned on, quickly press the appropriate filter monitor button. The

pre-filter light will flash up to 3 times and the HEPA filter light will flash up to 4 times,

depending upon how much expected filter life has been used.

PREFILTER:

1 flash = from new, up to 1/3 expected life used up

2 flashes = between 1/3 and 2/3 expected life used up

3 flashes = between 2/3 and all of expected life used up

Remains on = time to check/replace pre-filter

HEPA FILTER:

1 flash = from new, up to 1/4 expected life used up

2 flashes = between 1/4 and 1/2 expected life used up

3 flashes = between 1/2 and 3/4 expected life used up

4 flashes = between 3/4 and all of expected life used up

Remains on = time to check/replace HEPA filter

To RESET Filter Monitor

When the filter monitor light remains on, it is time to check/replace the filter and reset

the filter monitor, if needed. With the unit powered on, press and hold the appropriate

filter monitor button down for approximately 5 seconds until the light turns off.
Depending upon your individual usage (environment and hours

IPhone 3G battery problem


My battery on my iphone used to only last a day when limiting my use. And when I tried to use it normally with all the apps and music and calling people it only went for 10mins and then turned off.

How I fixed this:
It's an ongoing solution. I charged it up until it said 100%, then used it all up until it shut down again. And then I charged it til 100% and then depleted it again. Repeat over 2 weeks and your battery life should get back to normal. It worked for me and now my iPhone works better than ever!

Battery life expectancy


The battery life of AA alkaline batteries varies according to the manufacturer and power rating. Alkaline batteries can provide up to 100 shots with typical usage. Olympus NiMH batteries (B-01 4PE) provide approximately 250 shots per charge and can be recharged 300 to 500 times. Olympus recommends the use of CR-3V batteries or NiMH batteries. Olympus sells an NiMH Battery set which includes a charger and set of 4-NiMH batteries. You can purchase this through Olympus dealers or through the Olympus Emporium (www.olympusamerica.com/store).
