How to Increase Samsung Galaxy S I9000 Battery Life

Samsung Galaxy S LogoWith so many firmwares for Galaxy S from 2.1 Eclair to 2.2 Froyo to 2.2.1 to the latest Gingerbread 2.3.2 and 2.3.3, many of us still feel that the battery power is very less in our Samsung Galaxy S phones. So, let’s check out what are the ways with which you will be easily able to save on your battery life with which you will eventually increase the battery life of your Galaxy S phone. As Samsung Galaxy S is powered with and Android operating system which means that you can make use of as many as options to save on the battery life and also most importantly the hardware part of the Galaxy S which has a 1500 mah of battery power is not bad at all considering the fact that its good enough to hold the battery charge for a day or may a day plus half.

No to Live Wallpapers:

When it comes to the Wallpapers, you need to always ensure two things, one is that with the use of the Live wall papers the battery discharges very quickly and also the second thing is always try to set the wall papers which are darker in colour as to make wallpaper glow it requires the pixels to be burnt which uses the battery, so lighter the screen the brighter it tends to be which results in higher consumption of the battery life. If you follow these both steps then you can save up to a total of 5% on your battery life. If you are currently using the Live wallpapers then you can change instantaneously to the normal wall papers by following the below pattern of chronological order for selecting the still wall papers. You can select wallpapers out of Home screen Wallpaper or from Wallpaper Gallery as shown in the below screen shots.

Use GSM Mode:

Though 3G has arrived with most of the operators, hardly people makes use of it, so in this case rather than selecting the Dual Network which automatically uses the WCDMA (3G) network where ever available. So, instead of using in the dual mode which drastically eats up the battery life as there’s a lot of internal toggling and searching for the 2G/3G network takes place which results in higher battery drain than compared to usual. So, if you don’t use 3G then simply switch to the GSM Mode and not the Dual Mode. You can simply follow the pictorial chronological order to set your phone into the GSM mode. You can first go to Applications > Settings > Wireless & Network > Mobile networks > Network mode > Choose GSM only option out of Dual and WCDMA options.

Use Power control Widgets:

With a simple power control widget you can control up to 5 biggest battery drainers at just one go, the five parameters which can be controlled are Wi Fi, Blue tooth, GPS, Sync and also the Brightness of the Screen can be controlled very easily with the help of the neat and intuitive control widget which can be placed in any of the home screens. This widget is very useful for all those who wish to quickly activate and de activate the options as per the needs rather than getting in to the Settings, applications etc. for turning them On/Off. All you need to do is to first just long press on any of the home screens, then tap on Widgets, after which scroll down to find the option called Power Control and tap on the same to select. By the below chronological order you can do the settings accordingly on your Galaxy S smart phone. If you have the lower battery or wish to save then you can turn off all the power controls like Sync, and all etc and also you can reduce the screen brightness by tapping on the last option of the power control widget.

Choose the Right firmware:

Choosing the right firmware too holds the key, many times due to slow speed of the phone too changes the battery performance from handset to handset. Out of so many firmwares which ranges from 2.2 to 2.2.1 to 2.3.2 to the latest Gingerbread 2.3.3, i personally will recommend all of you who want to save on the battery life is the XXJPY 2.2.1 which is the stable yet one of the biggest battery savers and also if you feel that its bit laggy which isn’t at least for me then you can follow the procedure to Voodoo it so that your phone is speeded up to 3x times than the stock XXJPY firmware. Not to worry, by doing this you will neither lose your phone’s warranty nor you will be rooting your phone. So, just go ahead and select the right firmware for your phone. Do, note that this procedure is only applicable to all the Samsung Galaxy S GT I9000 phones and not for similar looking phones like Mesmerize or the Captivate or any of the other Galaxy Android family phones or else your phone will be bricked and will become no less than an expensive paper weight. Also, most importantly do follow the steps carefully before changing the firmware as if you are in any other version of the firmware like say on 2.2 or on 2.3.x versions then first follow the tutorial for installing XXJPU, then follow procedure to install XXJPY and then flash your phone with the Voodoo Lag fix.

Use applications wisely:

Yes, Android and multi-tasking can’t part ways but it’s not recommended to use 5-10 apps at a stretch simultaneously as this loads the battery to the maximum which then discharges the battery very soon. Also, never make use of applications like Advanced task killers as they themselves eats up lot of battery life which in turn reduces the battery life for your Galaxy S.

Maintain battery:

It’s one of the important aspects of the battery maintenance as you will have to ensure that once in two months you wipe the battery contacts with a piece of dry cloth and also most importantly never pull out the battery more frequently as this may loosen up the battery contacts which will in turn not only reduce the battery life but also will spoil the battery very fast after which you will have no other option other than buying a new battery.

So, that’s it by following the above tips you will be saving good amount of battery life. Do let us know if you face any un usual battery trends as we will be happy to help you out in the same.

    My Samsung Galaxy I9000 has very poor battery life. 1 10 minute phone call and a few facebook checks and it’s dead within 8 hours. Sure this can’t be due to the above issues and there is an actual fault?! It is so poor that I would return it on warranty but the battery is not covered. Can anyone help me with this?

    My biggest problem the Samsung Galaxy is the battery life. I had to buy an external battery pack for travel. I purchased the Phonesuit Power Core. It charges my Galaxy and wife’s iPad. Maybe the next Galaxy will have better battery life.

          Many battery manufactures doesnt recomment over charging of batteries as that will reduce battery life. Best way is to charge it for about three hours when battery low indication comrs up.

      @jithin yes all the contents will be cleared, you need to clear the cache as that makes phone slower!
      after flashing XXJPY you can install Voodoo which will make your device 3x faster!
