Help Just Got Off The Phone With HTC.. They Now Know What Is Causing Battery Drain..

FYI- I visited this thread yesterday and followed this advice from the link in someones sig above and this has made MAJOR improvements on my battery life, by this exact time today 9am to 3pm my battery was down to 15% with all radio's off, ATK killing everything and onl brief texting, facebook, internet usage. Today I now have 75% battery life left after following this-

"press HOME, and bring up the dialer. Dial *#*#4636#*#* (Do not press "Call"). After a second, it should bring up the "Testing" menu.

Go into Phone Information, press MENU, and tap "select radio band." You should experience a Force Close, don't panic, this was supposed to happen. Scrolling down shows that the preferred network type is GSM auto (prl).

What this means is that even though you are connected to a CDMA network, your phone is trying to find a GSM network, preventing the radio from sleeping, and causing excessive battery drain.

Remedy this by tapping GSM auto (prl), and changing it to CDMA auto (prl).


Now your done, your TWS should drop dramatically, and you should experience much better battery life!"

HTC guy states Sprint and HTC are working day and night to try and fix this issue and here is what it is. Its an incompatibility between the EVO and Sprint towers equipped with Motorola made transmitters. It seems that the phone and the Motorola towers have an incompatibility issue causing the EVO to keep searching for the tower even though its connected using gobs of power doing so. He also said they are not sure if it can be fixed with an over the air patch or not that it may end up being a hardware issue but Sprint is trying to modify the towers to compensate for the issue.

Sorry, but this is laughable

Ah. Way good point.

Still - I wonder how many people don't notice.

AFAIR, the Mobile Network widget wasn't pre-loaded on that wacky page to the left of home....

Just saying, maybe 4G users could get better luck turning that off if they know they don't need it. (?) Isn't being on WiMAX a wholesale replacement for all our data needs, when running in the normal scenario (not as you mention)?

I won't travel to my first 4G spot until maybe next month, so I'm quite curious.

IF 4g is on, there is usually no need to have 3g on as well.
 
that when I put my phone over my left nut rather than my right the battery decreases substantially...hmm must be the towers not liking my left nut LMAO!!! :p

man...can we make this battery fix a friggin pop-up, these threads are getting ridiculous.

Your fix:
1) Only applies to people with incorrectly set up phones.
2) Only applies to individuals with TWS above 0%.

My Time without signal is 0% and I get on average about 8-10 hours usage, which isn't horrible but it it's anywhere near what I would expect. My Palm Centro got that with a 2.5 year old original battery.

We now return you to your regularly sized fonts...

I'd love to see some sort of tower map if this is true.. it would help us determine if it is the sole cause of the battery issue claims or if there are perhaps multiple factors involved and the tower issue is just one of many...

Well I tried this today and nothing happened. I dialed in *#*#4636#*#* and what I dialed just dissappeared and nothing happened, no testing menu, no anything. It was almost like my phone would not accept 12 symbols/numbers.

Those dialing codes don't work with Froyo.
 
I've done all the battery tricks and prl updates and have seen absolutely no battery improvement. I will drop to 92% within 5 minutes after I unplug and this is with no use at all. My Hero has bad battery life too. Sorry guys I'm convinced that HTC stands for "Have To Charge"

Again - once the phone hits full charge, the LED stays green, the indicators read 100% and it starts running off of battery and will do so until around 92~93% and then start on/off charging.

It does this to keep the battery from blowing up.

It's just like a laptop in this regard (the same thing that leads people to think their perfectly-fine laptop needs a new battery).

Take your phone off the charger the instant it hits green - or even at 98 or 99% and it'll stay at the high charge.

The phone is NOT dropping to 92% in 5 minutes - it's taking 5 minutes to accurately reflect the charged state - and the number of minutes will vary slightly, just like on a laptop.

Dang that man is smart! Some folks need to read the entire battery tweaks thread before making assumptions. Or maybe I'm an Android nerd.

I learn a lot in these forums - including that very tidbit that my EEs have tried to explain to me for years, but it was just my laptop, so they bored me and I never paid attention until I read it here.

My premise is we're all in this together.

I already went through the steps of cycling the battery and turning off radios and apps and all. If any change was made it was barely noticeable. I have done my research on this forum regarding this issoue.
