[Sony Xperia P, U, Sola, Go] doctor_droid:
Hi all ;)

Here are a few tips i would like to share wid u all. These tips will help u extract the maximum juice out of your xperias ;)

Starting wid the simplest one

TIP NO 1 - ENABLE EXTENDED STANDBY MODE IN POWER SETTINGS

If u are on stock ics rom , go to settings, power management and check extended standby mode.

yes do it, this doesn't affects battery drain but enhance the standby time .:cowboy:

This helps to switch off wifi and data traffic when the phone screen is switched off for sometime.

Basic but most useful. :cool:

When this is enabled , u dun need apps like Juice defender or DS battery saver

TIP NO. 2 - DO NOT USE ANY APP KILLERS OR TASK MANAGERS

Most of us use task manager to kill apps running the background regularly.

But we may notice that most of the apps killed by task managers get restarted by themselves.

Thus all these app killers continue to drain battery and do the same thing all around,:eek:

These app killers will also make your phone laggy to some extent because of poor ram management

TIP NO. 3 - UNDERCLOCK

If u use your xperia only for basic purposes such as messaging and calls then there is no problem in underclocking.

800Mhz would be fine wid minimum or no performance glitches.

This not only relives strain on cpu but saves battery.

I myself have underclocked this and belive me 800mhz does not affects the performace of most of the games(if u play) ;)

TIP NO. 4 - USE GOVERNORS

There is no defination for governors but u can say these are the engines that control the cpu frequency time to time

There are several governors present most commonly used being ondemandx , conservative and powersave.

1: OnDemand Governor:

This governor has a hair trigger for boosting clockspeed to the maximum speed set by the user. If the CPU load placed by the user abates, the OnDemand governor will slowly step back down through the kernel's frequency steppings until it settles at the lowest possible frequency, or the user executes another task to demand a ramp.

2: Performance Governor:

This locks the phone's CPU at maximum frequency. While this may sound like an ugly idea, there is growing evidence to suggest that running a phone at its maximum frequency at all times will allow a faster race-to-idle.

3: Powersave Governor:

The opposite of the Performance governor, the Powersave governor locks the CPU frequency at the lowest frequency set by the user.

4: Conservative:

A slower Ondemand which scales up slowly to save battery. The conservative governor is based on the ondemand governor. It functions like the Ondemand governor by dynamically adjusting frequencies based on processor utilization. However, the conservative governor increases and decreases CPU speed more gradually.

For setting up governors (if installed) and underclocking use a free app like Antutu Cpu Master (https://play.google.com/store/apps/details?id=com.antutu.CpuMasterFree&hl=en )

here are the governors for Xperia U only

TIP NO. 5 - DON'T INSTALL APPS UNNECESSARILY

This does not needs an explanation. Just remember that when apps run in background , they consume battery. More the number of unnecessary apps running, the more faster is the battery drain.

Keep only those apps which u use frequently and if u are a rooted user, delete all bloatwares, FREEZE GMAPS AND TIMESCAPE IF U DUN USE IT.

TIP NO. 6 - CHOOSE NETWORK MODE AS PER YOUR NEED

Whether you are using WCDMA or GSM network or WCDMA/GSM , choose it as per your need.

If u are on the internet only for surfing then use GSM mode and switch to WCDMA only if u need to download.

This as per my usage has the greatest impact on battery life.

to select network mode , go to settings>more>mobile networks>network mode

While surfing only (xda :D) i use opera mini app wid GSM mode enabled and its very fast .:cool:

TIP NO. 7 -SHUTDOWN ONE OF THE CORES USING AN APP "XCORE"

An app by xda member blievenhack can switch one of the 2 cores off thus saving battery

Thanks to blievanhack for app and jonathan for letting me know :D

Here is the post link for xperia xcore

P.S. - charging your battery only when it is about to get exhausted belongs to old school now. Charge whenever u can charge ;)

NONE OF THESE TIPS REQUIRES SOMETHING SPECIAL OR TECHNICAL :cool: TRY THEM AND U WILL DEFINATELY FEEL THE DIFFERENCE :D

I hope you like my guide, its not copy pasted , its not stolen:D from someone, its purely my experience.

If u find any discrepancy plz let me know.

Feel free to share your tips here and discuss your experience ;)
