Can't Believe my Touch Pro Battery Backup

Well, I am not complaining. I am surprised and I am here to share with you all my battery backup.
I have last charged my phone 4 days back and I still have half of that green bar left.
Its been some 8 months or more that I am using my phone and the battery backup never lasted more than a Day. I use to charge every night and the battery use to drop to less than 25% by the late night. I didn't panic though. I use to read about others experience on the battery backup and given the features and usefulness of the phone, i have no regrets what so ever.
I didnt upgrade anything on my phone including the ROM,
But I am quite surprised that its been 4days that I last charged and the battery is still at 50% and my usage didn't change a bit.
Am I going to get the backup that the HTC spec talks about?
Guess what? my GPRS is not working for some reason since a week now and i believe that is helping the battery. When the GPRS was working, it always use to be on air and even if I disconnect, it reconnects and stays that way because of automatic email checking.
But if it is really the GPRS, how do i live without that when the device itself is build for messaging and emailing? How do I optimize this?
What do you think ?

What "battery backup" are you using? Is this an external battery pack that you plug in?

No stevens, i am using the default battery that came with the HTC.
By saying Battery backup, i mean the standby time.

In diamond tweak you can choose to disconnect your data connection after not using it for 10 sec. through to 10 min. Try this, works just fine on my TP.

pointless thread please delete
of course the battery lasts if the radio is turned off

Automatic email checking uses a LOT of power so it is not wonder your battery lasts longer when it is disabled.

I'm not talking about turning the radio off, I'm talking about turning data connection (GPRS, EDGE, UMTS, HSDPA) off. It's a different thing mate.

also turning off 3g will make the battery last longer since it doesn't constantly look for 3g signal

as the guys here stated, as long as you turn off (or that they're off by default) the data connections and gps,your battery should last a good amount of time.

Wifi time-out OFF by default?

So, it seems the default policy for wifi on this device is never to disconnect itself to save power. The Vibrant defaulted to whenever the screen was off. That makes the default wifi policy between these two devices vastly different. In fact, there isn't even an option on this phone to disconnect from wifi when the screen is shut down. I wonder how this will affect battery life. I may think twice about enabling wifi.

The first thing I did after connecting it to my wifi was go to the wifi advanced settings and set the sleep policy to never. I'm glad it was already off by default. It shows that someone at HTC paid attention to that small detail and how it affected battery life. It greatly helps your battery life in my experience (with the Vibrant), since it's not constantly connecting and disconnecting from wifi which apparently uses more power.

Really? How would that *improve* battery life? I would have it to *detract* from battery life. If I'm at home basking in my wireless network, why would I rather have the connection permanent than to have it disconnected when the screen shuts off as it does by default with the Vibrant? If what you say is true, then setting the timeout from the 15 minutes timeout, as I have it now, to full time connection (never timeouts), will actually save on battery? To me, that flies in the face of reason, but then again, stranger things I've come across.

Just hoping for a reply to the above, and perhaps someone can explain why having wifi never time-out even when the screen is off can lead to better battery life?

think about it. having to connect and reconnect everytime you turn on your screen is bound to eat up. if your screen is off its not sucking in massive amounts of data so the battery drain is at a min

Well, it's certainly not intuitive, and I am thinking about it, hence the post. In order to maintain an active wifi connection, there has to be continual pinging back and forth even with no active data connections from the device. Now, we all know that there *is* a lot of data being exchanged when the screen is off - whether it be syncing accounts, retrieving news items, emails, etc. This would all be taking place over a wifi connection by default. It is also my understanding that using your wifi radio consumes more power than your UMTS radio does. However, I'm not entirely sure of that last point.
Isn't it far more intuitive to believe (whether factual or not) that having the wifi radio powered on unnecessarily while in your pocket would consume more power than having it turn off? Even the seasoned users over in the Vibrant forums all recommend setting the wifi to turn off when the screen shuts off, which is a setting not available on the MT4G.
I'd like to believe that how HTC sets the default wifi behavior conserves power, but it sort of flies in the face of reason. I'm also of the belief that the device is set by default the way it is so that callers who use Wifi Calling can always be reached while at home on their wifi network. But, having such a wifi connection setting is actually eating up your battery life if you don't need wifi calling.

Wifi used less power that edge/g3/4g. Having it constantly on wifi with improve your battery life just because when wifi is enabled it shuts off cellular data.

I have. I have a vibrant. Ordered the mytouch last night.

Also, can't have WiFi sleeping... otherwise WiFi calling won't work...

Battery improvement all of a sudden

I noticed yesterday that for the first time at work that my phone doesn't show the 2G icon (I have the use only 2G networks tab checked), just the wifi signal, and that the battery lasts waaaaay longer. Haven't noticed if it does that yet with the wifi at home (hasn't before either place, it would show both icons). But I'm going to check this evening. Not sure what changed, but I'm glad, now getting 10-12 hours under moderate use instead of 6+. I'm aware this may be old news but I didn't do anything to change it. fyi

That is great that your battery improved. Do you remember making any changes to Apps or sync settings?

The phone lasts much longer when using Wifi for the data connection. I can make it through a full workday connected to wifi, well usually anyways, but on the network I have to charge at least once, often more.

If your phone was showing 2G and wifi, that means it was connected to both but only using 2G. Its a bug and you should try disconnecting and reconnecting if it happens again. Or restart the phone.

After reading this post I went ahead and selected 2G network only and turned on my Wifi. My battery lasted MUCH longer.

2G should last much longer than 4G.

Try CM7 #38. 10am-midnight @ 67% left.
I think they fixed the battery drivers finally.

Does Wifi Save Battery vs Cullular connection?

If your connected to wifi and using it, are you gonna get better battery life VS being connected to either 3g or 4g/hspa+?
and Why if so?

Shoot im sorry, this shouldnt be in this forum. I thought I was in the general questions forums. MY bad people. Please move mods.

This is the General forum. To answer your question, Yes it would use less battery on WiFi. On a data connection the signal is not a constant and the phone is always looking for a stronger signal.

Thanks, thats what I thought. And ive noticed that connected to wifi my battery lasts a lot longer.

yes. And 4g eats your battery.

When I am only using the phone for data, I use WiFi when available. I turn on airplane mode then activate WiFi.

I don't know about that... when I'm on wifi my battery drains like a mofo. Weapon 3.0 ICS theme faux 1.3 kernel.

On every ROM and Kernel I've tried, Wi-Fi uses much, much less battery than 4G. I haven't tried any of the toggles / battery saving apps though so I'm not sure what effect those might have.

Do you disable data when you use wifi?

He shouldn't have to. If he's draining faster on WiFi then something is screwy with his setup.

On stock, cyanogenmod 7.1, and cyanogenmod 7.1 with various other kernels I've experienced increased battery drain with wi-fi on and connected with the phone sitting at home the entire day. Turn off wi-fi and let it just use the data connection to T-Mobile and I get drastically increased battery times. I'm assuming those of you who get better battery with wi-fi on are in extremely bad signal areas. Also, if you're on cyanogenmod have you turned off the auto wi-fi disconnect when sleeping feature? If you haven't then your battery life when sleeping should be the same as that of wi-fi turned off.

Wi-fi should always be priority if your in range.

Well my personal experience has been that wi-fi eats up battery like crazy. Same thing happens to the other smartphone users I know around here so I was surprised to see that people get better battery times with wi-fi on. Are you guys completely turning off your cellular radio? I don't like the quality and slight delay of wi-fi calling so my cellular radio stays on when I have wi-fi on.

I don't usually notice much difference between wifi and 3g battery drain here (no 4G for tmo here).
As someone already posted, my drain is worst when 3g signal is poor, like when I'm at work and the metal building interferes with everything.
Have you tried checking logs while connected to wifi to see if maybe some app or service goes crazy?

Nothing fishy going on when wi-fi is on. I get about 10-14 hours on battery with wi-fi on and next to no use of the phone vs somewhere around 20+ hours with wi-fi off and similar extremely light use. I keep meaning to do some more standardized testing where I literally don't touch the phone but life gets in the way and I have to make/answer a call or txt or whatever so I can't nail down any hard numbers. Typical experience on a slow day for me is that if I forget my wi-fi is on, my battery will be somewhere in the 3-5% range when I'm getting ready for bed while if I hadn't left it on, I can go to sleep and wake up and it'll still be hanging in there.

That's true, I've always believed that Wifi eats battery faster because someone(don't remember who) always told me that Wifi uses more battery because it processes data faster, but I always noticed that when I used 4g, it drains a lot faster.
I always blamed it on the ROM, but I can see that it's not the ROM's fault.

question on leaving gps and wifi on.

so.. do they use battery if they are on but not used? i have read yes and no. do they use battery if on but not used?

I leave both on and my battery life is great.

Install a battery monitor app (the one that provide how long your battery going to last), when you enabled gps, it showed a 2 hrs drop from the total, so the answer is yes even without using it. A big surprise between wifi and 4g, they consummed almost the same power, only 10min less from the wifi.

Yes.
GPS still tracks where you are for apps running in the background (e.g. Google Now).
Wifi is constantly searching for a connection when on. Staying connected to wifi also takes battery.

I have extensively compared both running with the GPS on all the time & never using it at all.
It made virtually no difference whatever in my battery life (unless it's actually doing something which is infrequent, it really uses no battery at all), so I leave it on 24/7.
I have done this in phones all the way back to my DroidX & don't give it a second thought at this point.

Also tried many tests to see if wifi and gps on/off makes a difference. Almost none, leave them on, even BT left on didnt' make much difference.
