How long does your i-phone battery last ?

[StonehamPark]

That's remarkable. If I'm somewhere with only my phone for entertainment, such as when I'm getting the train down from the sticks to Brighton for a game, I can get through a whole battery charge by lunchtime.

I imagine email fetch/retrieve & location services drain a lot of the battery. I'm really tight fisted with all that stuff, keep it to a minimum.
I've also aquired OCD on immediately closing any and all background apps once I've finished with them and keep the screen at near minimum brightness.
I'm guessing I'm in the minority however.

My brand new 4S lasts less than a day and thats without watching youtube, sky go etc ! Should i send it back ?

Thanks.

My 4S lasts almost two days depending on usage. I usually top up each night and the % is showing between 40 - 55.

I'm likewise - location services are off by default, and only turned on when I specifically need them and have fetch set to manual too. Brightness is at around 50% and auto-brightness is off.

I don't often close down all apps because I know that most don't make any difference to battery consumption - that's a bit of a myth.

I still have an I phone 3gs. It still lasts a whole day with ease using it quite a bit too.

I have had it for about 3 years now and wouldnt replace it.

This. Mines fine unless I'm watching porn I mean YouTube!

High temperatures may shorten battery life, 35º+, we've had a bit of nice weather recently? Don't leave it in the car where it might get even hotter in the sun.

Lithium-based batteries need to keep the electrons in it moving occasionally. Make sure you go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

Optimize Your Settings

Minimize use of location services:
Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.

Turn off push notifications:
Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.

Fetch new data less frequently:
Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.

Turn off push mail:
If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.

Auto-check fewer email accounts:
You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.

Turn off Wi-Fi:
If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.

Turn off Bluetooth:
If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.

Adjust brightness:
Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.

Turn off EQ:
Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. This will also improve the quality of the music you hear, EQ fucks it up.

Whilst abroad I leave it in airplane mode (so not connecting to any network) and battery life is in the region of two and a half days. Switch Mobile data back on and without doing ANYTHING else it plummets to less than a day.

I'm a passenger in the car and have been using my phone throughout. 50% of the battery used in 3 hours..

close down the apps as they are eating through your battery.

double click the button at the bottom and it will show all the apps that you have open, hold your finger on one of them and they will start to shake.. then just delete them all.
this will close them down as opposed to getting rid of them completely and your battery will be restored to normal........ i thank you
