Hey guys…. First and foremost.. Would like to wish all my Muslim friends Ramadan Mubarak / Selamat Berpuasa.. May Allah’s Blessings with you all.. =)

iPhone is like the talk of the town these days! Just few months back 3GS was launched and the response for it was overwhelming… As far as I know; there are still plenty of customers whom are still waiting for the next arrival stocks of iPhone 3GS.. Keke! I was one of the lucky one whom got it in my companys’ roadshow; even without having to pre-order or waiting for it =D … Ok… Yeah was pretty excited about it; even though I did not had the heart to let go of my all time favourite Nokia… All right.. Surprising.. for the first time I’m going to post about a technical stuffs, as I’m using this 3GS iPhone, I do experience low battery life which is annoying me big time.. Guess this is one the side effects of Jailbreaking though…Or probably its the software.. Initially I was having second thoughts about Jailbreaking.. but since I trusted my colleague[that day itself; he jailbroke couple of phones...keke!] who is like a pro in that.. I was very much into it.. And that too its reversible.. So y not!?? Hehe.. I’m one of the Junior in my team to hold an iPhone ;)

Ok ok back to my story.. Yeah! When I went to bed about 12 plus that night the batt was about 70% and the next morning when I woke up at 5; my phone was totally off!! I was not even able to boot up that I freaked out!!!!! Hmmm.. thats where I realised that my colleague actually sent an e-mail some time back on tips regarding this battery consumption issues.. & thought why not share it here… =) If I’m not wrong he got it from the hardwarezone forums… Anywayz thanks to him(Paul) though.. My cousin brother tried the methods and it actually lasted him about 3 days!!!!! I am in the process of following the tips too :) Here you go….

Like in every new firmware, many iPhone OS device owners all over the web report battery life issues after upgrading to 3.0. The reason this time however, is mainly because of Apple’s Push Notification feature. I had upgraded to iPhone 3.0 during the beta and I noticed that the battery life drains about 1.5x faster than 2.2.1. But with the public 3.0, I feel as though it’s 3x as fast. It appears as though all the new features that have been implemented into 3.0 are pushing the devices to their limits. I noticed many hang ups and frequent freezes after some moderate usage of the iPhone. Even a great application called FreeMemory doesn’t seem to do the trick.

This is most likely a software issue that came bundled with the new features, settings, interface, etc. Some of the causes for the possible “iDrain” are Copy & Paste, Push Notifications, added MMS, iPhone tethering ability, Bluetooth A2DP, application incompatibility, and unstable jailbreaks. It can’t be helped though, at least Apple rolled out a iPhone SDK 3.1 for developers to fine tune their applications for smooth performance on the current and any future software updates.

*Here’s a few pointers that may help you out:*

*Mail, Safari, iPod, and Text are stock applications that can run in the background. Simultaneously running these will take up A LOT of system resources. If you are jailbroken, use SBSettings to end some of these processes.
*Turn off 3G.
*Turn off Wi-FI.
*Turn off Push for e-mail accounts and syncing servers such as MobileMe.
*Turn off Push Notifications for applications.
*Turn off Fetch.
*Keep the iPhone on standby when not in use.
*Set an auto lock time, you never know if you might accident forget to hit the sleep button, resulting in the possibility of extreme battery drainage.
*Spend less time on heavy-graphics games/applications.
*If you have an alarm set, but don’t need it, turn it off.
*When you want to go to your photo album, you have the option to go to it through your Camera.app but doing so will keep the Camera application running WHILE the Photos application is running as well. (does not apply for iPod touch users).
*Don’t use copy and paste unless you need to; using it creates a process called “pasteboardd” which remembers your copied/cut text. Copying/cutting pictures or large strings of text will slow down your iPhone as pasteboardd keeps the info until your next reboot (or next copy/cut).
*Your Phone application is ALWAYS running in the background, even on Airplane mode (iPod touch users will not have this process).
*Use a paid application called Free Memory to flush out some RAM and squeeze in room for other applications. (Note: The current version does not work well on 3.0. The developers are coming out with an update soon).
*Don’t install WinterBoard; it can take up anywhere from around 5-30MB. Besides you are better off plain and simple than slow and unresponsive.
*Disable MobileSubstrate add-ons that you don’t use by going to SBSettings>More>MobileSubstrate Extentions
Or just don’t install MobileSubstrate.
*Don’t unlock if you are on an official carrier.
*Remove applications you rarely use.
*Get the latest updates for App Store applications; they usually make the application faster, less buggy, and more battery efficient than the version previous.
*Don’t jailbreak.
Reboot fairly often.
