[TIP] Greatest Battery saving tip you'll ever find

---

Hi all.

I tried this originally on my desire, then in my wifes wildfire S to great success.

Go in to the phone app
type in *#*#4636#*#*
Select 'Phone information'
scroll down to the bottom
in the 'set preferred network type' select 'GSM auto (PRL)'
then press back to return to your home page.

The wife doesn't use her phone much, ie a phone call or two a day, after a DAY of being unplugged from the mains the battery was still registering at 100% !

This doesn't affect the phone's functionality at all, it still allows for you to connect to a 3G network, what it does is connects to 2G when the 3G signal is weaker for calls and texts.

You may get varying results but every phone I've tried it on has boosted the battery by hours when idle.

Enjoy!

Updated with proof

Hi guys, just to show you how much better this setting is, my wife's wildfire S normally needed charger every 2 days.

As you can see it's passed 2 days and it is still registering over 80% remaining battery.

I'll update when it finally dies, which should be in about 8 days

tried this on my wildfire s and afterwards it just kept turning my network on and off.. Switched back to wcdma preferred

I haven't seen that before, you might be in a weak 2g signal area thats why it's constantly trying to resolve the radio.

I assume this will work for some ( I live in an area that is very well covered by orange) and not for others depending on your network coverage.

Does it still do it when you switch to GSM only? It will kill your internet speed, but just to test if it's the 2G mast or not, then switch back to WCDMA preferred if it works best on your phone.

If GSM only is okay, you can use widgetoid 2.x and make a short cut to the normal settings options to switch between gsm only and WCDMA which will help, but I find it a bit of a pain in the perverbial behind.

As with most tips its not a one size fits all, however I've done it on 5 phones ( all HTC) which has improved the battery.

Hi,

as for me, I have really a lot of problem regarding the battery life.
Today it was 100% and after 8 hours just 55% left.
Without using any wireless conection, and just 2 text.

Any way, maybe you can tell us, how is the wildfire S form your configured, homescreen widget?
which battery tool do you use?
I just made again a reset, and I will try to set GSM only, coz I do not use internet at all.

by the way, great thread.....)

bye

She's got it extremely basic, no widgets, no weather nothing, there's only 4 shortcuts on all her home screens, mostly black background (static picture).

No battery apps or task killers are on it.
All radios, GPS etc are disable, screen brightness on auto ( however I usally leave it around 20% for better battery performance)

It is never connected to the internet, she uses it just as a phone. I'm quite impressed with the battery life she gets.

I'm a bit curious, if she just used it at the most basic level, than why would she get a smartphone?

Hi Guys,

Just a quick update, the phone has made it to over 6 days stand by and the 30% energy saving has only just kicked in.

What I wanna know is, is there a way to log (appart from logcat) what's going on it the background. Granted she doesn't use it a lot (mostly as a personal radio and because it was a free upgrade to answer the previous question) but if you look the angle of decline increases after use when surely it should sharply drop and then continue on the same curve?

Nevermind.

This means her phone is up to 151ish hrs standby and still going, I'm gonna have a few more tweaks and see if I can get it anywhere close to the times quoted on the HTC site:

Standby time:

WCDMA: Up to 570 hours
GSM: Up to 360 hours

Infact (sorry i think outloud when I'm typing) how the hell do they think you'll get BETTER battery life on WCDMA? No chance unless you live under the mast and never leave the house.

I think for my next test I'll put it on WCDMA only and see how it affects the battery.

Also the battery doesn't have a very high capacity. That could also be the problem. I heave heard the hd2 I think has the same battery size but a much higher capacity.

I'm very happy with W-S, however the battery is a HUGE problem.I did some research (got my device unlocked with XTC clip) and so far, the best way to save battery, is to root your device and use setcpu. I will do more tests, but i'll probably search for 3rd party battery.
