A better iPhone 4s battery life

Since I got my iPhone 4s I was very disappointed with the battery life: it looks like I'm not the only one..


During the last days I found several solutions that really improved my battery life 🙂

You have to read for days to find the good tips among hundred discussions, this is why I'm sharing those here

I'm still hoping that Apple will do something soon to improve IOS5 battery eating disorder


1) Fully charge the battery with the iPhone off

At night -or when you do not need it- plug in your iPhone to the charger , then switch it off

pulling the red tab on the screen and let it charge.

Do not switch it off before and plug in after because

the iPhone will start back automatically


The battery will go to 100% and it will last longer

This is a procedure I have done in the past even with old iPhone and iPad and I always found that works great.

Same for laptop.


2) Turn off Setting Time Zone function

in Locations (system services). It never turns off location searching so it drains the battery.

This setting was draining my battery 3% in one hour with everything off.



3) Turn off Diagnostic & Usage Data.

Settings > General > About > Diagnostic & Usage > Diagnostic & Usage Data.

Another big improvement


4) Brightness at the minimum you can stand


5) iCloud off

I use it to sync when I'm at home and with wi-fi for now: hopefully Apple will come up with some fixes


I had to kill several operations to get a decent battery life: I do not think this is what you need to do when you buy an expensive phone

Everything should work fine and the battery last as long as promised...


6) No iCloud cellular use

Settings > iCloud > Documents & Data > Use Cellular = OFF


7) Turn off Time Zone and Ask to join networks


8) Do not leave iMessage in standby when you do not use it

Quit as soon as you finish sending messages



Thanks to everyone who suggested all these tricks : it's difficult to go back and find them all but

my gratitude goes to all of you !

iPhone 4S, iOS 5

I heard about this (turning time zone support off) in a number of places and did it, but no joy, battery life was still getting eaten up.


But that caused me to then think about the weather app/wdiget constantly checking my location whenever I opened notification centre. I know from elsewhere that location checking can be a big drain on battery.

I have an iphone 4s and I have also discovered that in the email settings, selecting to 'fetch manually' has no affect on emails being pushed to your phone whenever they are received.

I tried this after randomly getting an email alert today, and wondering how it happened when i didnt refresh my emails, and I wasnt even using my phone at the time!

I checked that the main option for 'fetch manually' was selected, and sent myself an email from my computer.. within seconds my phone vibrated telling me I had an email.

Instead, you have to go into advanced menu and select fetch manually on each of your email accounts!

This is clearly draining the battery faster than usual and I recommend everyone checks their advanced options if you prefer to manually fetch your emails and increase your battery life.
