Battery use - Fascinate Q&A, Help & Troubleshooting

Even running PW edo5, screen set low, and all other battery saving tips, my display still uses over 80%. Was wondering if anyone had any advice.

Use the phone less... jk.
I use two utilities to save battery:
Screebl Lite will use your accelerometer to automatically keep the screen on if it is being used or turn it off if not (if the phone is flat it lets the screen turn off.) It can be useful so you don't have to turn the screen on and off a lot.
Screen Filter puts a dark filter over the whole screen, to allow the phone to go way under the default brightness setting. It isn't really practical during the day but it saves a lot of battery if you can set it even at 50% and lower at night, in bed, etc..
and make sure that you aren't leaving wifi and data on when they aren't being used, same for bluetooth, gps, etc. to save battery overall.

It stands to reason that your display will use the most energy. All that 80% is telling you is that while your phone is running it is using a certain amount of power, of that certain amount your display is using 80% of it. I don't think it will ever use much less than that no matter what you do. After all when you are using your phone that is the one thing that is always active.

Why not just keep spare batteries around? The last time I ordered batteries I paid $2 each for Samsung batteries out of China. They are the ones for the Epic maybe, but the same thing other than color. Requires a custom kernel (pretty much any kernel now other than stock) to charge them in the phone. However I almost always use external chargers as I always switch dead batteries out.
Everyone worries about battery life, its a smart phone if you use it it eats batteries. All you can do is make it slightly better than it was. Or you can just keep a spare battery in your pocket just in case and use wifi, GPS, 3g, and still have a bright screen. I have 5 batteries and 2 desk chargers on my desk (2 fascinates in my house).

I believe in the Glitch V12 kernel, you can have custom display dimming settings. I'm not sure if this a completely objective observation, but it seems like I could get the dim brightness setting darker on this kernel than in the stock.

Well thanks for advice I will def give those 2 apps a look! And yes, I do use 2 batteries. The stock 1500 annd also an extended 2200 I found on Amazon. Great investment even though it does add some bulk. I use a battery calibration App with them. Just wonder if that App is enough or should I be doing some other type of calibration?

Should be fine, just make sure to be at 100% charge on the battery for best results.
Also let it be known that on miui with glitch my display uses 6% of my battery.

6% ????? On the DISPLAY? ??....WOW that's THE lowest I've ever seen! How is that possible?
Sent from my SCH-I500 using XDA App

6% is easily possible if you never use the phone all day. The system will hog all of the battery with the screen off. I think the most important thing is how many %/hour you lose when you are not using the phone. I think about 2.5 to 3% per hour is pretty typical for me.

70% battery use of display

I've had the 3vo since launch and lately my battery does hella fast. Whenever I check to see what has been using my battery it always says 60%+ screen and never 10%+ of anything else. I always have brightness dimmed and screen timeout at 30 seconds. Any ideas?

i know what u mean, i had the same problem but it eventually improved a bit for whatever reason. I think the main culprit is actually a wake lock thats causing the ****ty battery, not the display itself. Do you also have a high awake time?
The display usage being that high is actually a good thing. It means none of your other components are draining your battery excessively. The screen uses how much it is going to use and can't really run in the background and kill the battery like the cell standby, media server, and android OS could. I get great battery life, during a 10 hour shift at work my battery drops maybe 30% if I'm getting a lot of missed emails, calls, text. My display usage is 85%.
A thing to consider is that this is a percentage of battery use, not a microvolt value, so it's not really that useful for diagnosis just identification. One thing you could do is click each item listed and compare time on and CPU times listed.
Do you actually let the screen timeout every time or do you manually turn it off? Do you spend a lot of time using the 3D feature?
Basically if your phone is dying fast and display is the highest consumer, it is probably dying fast because you are using your phone a lot.
It simply means that your actually using your phone. People with 30 display is pretty much sleep sleep sleep. I get about 3-4 hours of onscreen usage.

I had one device that would drain way quick...same situation as you, with only a couple hours screen-on time. 70%+ display usage...
I took it back and forced their hand to give me a new one.
It has been working a lot better, I still use the phone just as much but it lasts much longer. It may have been a defective battery but it's probably easier to just exchange the whole device.
Good luck.

oh yes, the old 'return it' solution. lol fail
I'm pretty well versed with most diagnostic techniques to pin down what was eating the battery; believe me I tried all of it.
Sleep time was good, no apps sucking cpu cycles.
When the display was draining 30% battery per hour I figured it was a faulty display or faulty battery. Easiest solution within 30 days was to exchange.
The new one works great.

What apps do you use to help with battery life?

I currently have JuiceDefender Ultimate (Waiting on CyanogenMod port because it works best with it) No-Frills-CPU Control and Autokiller Memory Optimizer.
Phone is rooted
Personally, I dont use anything extra and my phone gets GREAT battery life

Why would you use those programs I'm sure they kill battery life faster I have lots of sync'd accounts on my phone and keep it on high performance and I get 16+ hours of battery with phone games and more if I turn on my custom battery setting from the stock battery manager I have gotten almost 2 days of life. You need to reevaluate bro battery on this phone is sick I even have an extra battery and have never had to use it.

I used my phone moderately with some email usage, calls and a few games and i got about 13 hours of battery life and had about 6% battery juice left to spare. How are you getting som much battery life? Did you do anything with the Sprint Bloatware? Did you uninstall some apps or freeze the. P
Thanks in advance....
I use Y5 to auto enable/disable my WiFi connections. Keeps the phone on Wifi as much as possible and I don't have to mess with it.
Juice defender does that. Before I had wifi constantly on, gps, 4g and battery wasnt what id expect. I mean ive never had it die on me yet but close. No frills controls clock speed depending on how much I need. Since ive installed juice and no frills battery is way better.
Sent from my MB855 using XDA App
depends on what im doing. If i plan to be using my phone in and out of my pocket alot, ill have juice defender turned on.
if i know im going to be talking alot that day, texting and not much need for internet, then ill just leave my 3g widget off for mobile network.
other then that, the phone has great battery life.
I must say, on my evo i got super annal about having full charge and wanting to keep charging it all the time. I swear id get an uneasy feeling in my stomach if it went below 50%. when i first got this phone and had the 10% marks instead of the 1% marks, my brain about blew up and i didnt know what to do! lol
but now ive began to like the 10% marks bc im not as annal about wanting to plug my phone in bc now i dont see the amount it dropped in the last few minutes.
in all.. i guess this phone was made for me, or like the windows 7 people "my name is logan, and i invented the photon"

I'm in the same boat as you. I've been using/trying juice defender and have it set on balanced. It says I save about 1.5% every day. I have to email accounts syncing, text about 50 a day and use about 10min of internet and I was down to 40% in 9hrs. This was with out make a phone call today. Juice defender doesn't seem to really help anything.
I use an app called Brightness Profiles from the Market. Used it on my old HTC Hero as well. Its a precise, quick and easy way to manually control the screen brightness. Most of the time indoors I have brightness set to 0 or 10% which is plenty bright for me and saves a ton of battery.

I was just noticing the brightness of the Photon's screen last night just before fallin asleep. My evo on 0% was DARK in a dark room, but at 100% in the sun you couldnt see. The photon seems to be in a different ballpark. 0% it still looks super bright and 100% is WOW a light in the sky.
when i look at when my battery is being drained the most, its def when that screen is on. i think a rom or theme with black/night colors will def help out because the bright colors of white are probably not any aid to the battery conservation.
yesterday i kept juice defender off all day. got 14 hours and 37 minutes till it hit the 30% mark and the icon changed colors. i had about 2 hours of web surfing, about 3 hours of total call time, and about 150 texts and almost a dozen MMS. (buddy just picked up a new chocolate lab puppy )
so im impressed. i def agree, looks like juice defender is not a good fit for the phone yet. the toggling radios on and off probably kills alot of power.
I have to agree, Juice Defender doesn't seem to be doing much. I get around 1.47-1.6 with JuiceDefender.
Other than that I run SetCPU with my profiles set up.
I some times when I am at work use a custom battery setting which pots screen at lowest and disables data during peak hours after 45 minutes of inactivity. It works great especially when I am at work and have some longer breaks between checking my phone. I also work and live right next to a sprint tower so I always have great coverage.

I still need to use juice defender ultimate for about a week to get a good history from it but right now im at almost 19hrs to full battery drain.
Sent from my MB855 using XDA App
Juice Defender, 36-38 hours before switching to 2nd battery.
Set to sync all every 1 hour. Twitter, corporate mail, 2 gmails, corp calender, contacts, etc.
The main difference is I set the screen to off in Juice Defender under toggles, not to trigger the data on just because I pulled the phone out and turned the screen on, doesn't mean I want to get on the web. I can easily pull up local info w/o that. In the morning, and in the evening, wifi is on for 30 mins or less each time to download podcasts on doggcatcher.
Lots of texts, calls , 150+ emails delivered a day, plenty of app usage, plenty of google.com searches. Maybe 1-2 app updates a day. Audio and video usage around 3-4 hrs daily.
I can go to work at 7:20 in the morning, get off at 5-5:30, and my batt stats are 75% left. Am usually sitting at 60-65% left by that 12th hour.
Can you let me know what your exact juice defender settings are? I have ultimate juice defender and am lucky to get 8 hrs per charge,

That's because you actually use your phone. These people who claim 30+ hrs of battery just have it sitting around most of the day not doing anything on it...very minimal use. For people who bought a smart phone to actually use the "smart" features of it, they will see anywhere between 8 -15, of good use. Keep in mind these phone are only rated for 7-8 hrs of continuous use, max. I say, use it how you want, don't cripple your phone with auto killers and apps that turn your data off, that's the whole point of your smart phone is to consume and transmit data. Use it how its meant to be used and enjoy it!

Well said. My advice is just find a cheep aftermarket battery and keep it handy just in case.

Why buy juice defender when the photon has these features built in. Just go to battery mode and chose "Maximum battery saver". After 15 mins it will turn off all syncing activity. Also when you're not using your phone turn off syncing completely it really helps your phone last 10-15 hours easily. I'm a very heavy user so while I'm at work I just turn off sync! Plus I also received a replacement battery from Motorola because my original battery had problems. I couldn't get more than 8 hours with the first battery (maybe defective) so they sent new one.
I agree with the post on people claiming 20-30 hrs.. they flat out dont google and drool over theyre screen all day.. like most others do though.. that is why batt life is always always will be a huge issue!
Nothing ever really will help kernels.. roms ...juice def..undervolting.. it really
dont make the huge diff people expect..
Samsung has about the best batt life youll find on an android device.. with the exception of a few devices.. dual core affects alot more than a noticeable benifit!
Only real option to date is a EXTENDED BATTERY!

There is much discussion on mastering your battery life in other sections, but concentraining on the app part alone, I would say Juice Defender has made a huge difference for me. I can get over 24 hours unplugged with about 3-5 hours of screen on time. The free Juice Defender helped a bit, but it wasn''t until I bought Juice Defender Ultimate that I saw large gains in life. I basically run my phone set up so that it kills all data connections and checks periodically (5 minute intervals) for notifications. Also, I have it set to learn so that when it knows I'm in an aread (based on tower ID, not GPS) that I do not use Wife, it will not bother looking for it. There are a ton of little settings that you can tweak to find just the right balance of saving verse use.
I've heard good things about Juice Defender as well.

I too rep juice Defender like a champ. however............
if your getting only 4 hours battery lift, then their is probably a more serious issues. Im not sure wakelocks alone could even account for such poor battery longevity.
I would also recommend CPUspy from the market. This is a helpful tool to make sure your phone is going into deep sleep mode.

The key question is 4 hours of what? If I sat and played games for 4 hours, my phone would be dead or close to it depending on the game.
Lol. Not even! Modern combat can drain 10% of my batt in 20 mins

you need to install BetterBatteryStats to find out what's eating your battery. I use to use JuiceDefender & my biggest complaint was it was having a hard time reconnecting to wifi once the screen was on. I got fed up & went to GreenPower which has more options, IMHO.
I can get 15-16 hours of run time with 4 hours of screen time with the following. No Juice Defender.
Wifi off. Data and BT on. Screen Filter set to 75% most of the time, and 30% in pitch black. Screen Filter is a biggie - even Juice Defender can't cut the power useage of the single biggest drain on this phone... the screen.
Pls say where I can find screen filter setting. Thnx
Sent from my SAMSUNG-SGH-I717 using Tapatalk
Turning off auto brightness, and turning off screen auto rotate (and enabling it only when needed) help quite a lot!
Screen Filter is an application. Its primary use is to dim your screen far lower than the stock "low" setting. In many people's opinion the low setting is still way too bright in a dark room - Screen Filter lets you go as dim as you want, although too low and it makes everything look gray which is why I stick to 30%.
I noticed that it works along with the built-in auto brightness setting, and the app will allow you to dim the screen only a little if you want, so I started using it all the time on a 75% setting. The screen will still brigten and dim based on ambient light, but it will just be a little dimmer than stock. I've found a 75% setting along with auto brightness works well in all situations except full sun or a dark room, so I have two Widgets on my home screen - one for 75% (most of the time), one for 30% (for a dark room), and I'll turn it off for full sun. A lot less fiddling around than turning auto brightness off and manually adjusting the brightness all the time.
Since LED screens use less energy the darker they are, this effectively extends your battery run-time.

Battery problems

This is my 4th note. The 3 I had previously the battery lasted a long time. I kept the same battery from the first one in all three exchanges. I took the new battery for this fourth one. Could this battery be a bad one or should I return the phone again for a 5th time. I don't wanna take a chance getting a phone with the problems I had on the other 3.
Just looking for some opinions

Good Lord, 3 exchanges! Wow... try running the battery all the way dead where the phone shuts itself down, keep it on the charger and charge it overnight (or in the realm of 8 hours) while leaving it off and see if that makes a difference. I ran my batt that way once and I'm getting 18 or so hours per charge (depending on how much I play with it).

Reflash your modem, rom, and kernel. See if that helps
I only get about 3 hours of screen time myself. Seems normal for this phone. The huge screen eat up battery fast. Plus if your using LTE, so good bye to your battery.
I don't think you have a bad phone, That's just how it is in my opinion...
so whats your total at the end.. like say.. 5%..?
If you're getting about 3hrs screen time, I'd say you'd be on par with what I'm getting. Some days I can eek out close to 5 hours screen time, usually on the weekends when im at home and on WiFi.

I don't know why you guys are getting such horrible times. With regular use I'm getting an average of 8-10 hrs screen time, depending on what I'm doing. I'm running Saurom RCVI, with Da_g OC Kernel, and tweaked a few of the JKay settings. I recommend charging to 100%, wiping batter stats, and doing a power cycle on it. That's what I did after installing above Rom/Kernel, and battery went from from 4-5hrs to at a minimum 7hrs.

I would like to see a screen shot of that
Fighting battery problems here as well. I'd assume it was normal for this phone, except when I see people posting great times.
1 week old phone. Switched to Saurom yesterday to see if it's any better. Screen regularly at 5%. Usually on Wifi most of the day (and I'm not in an LTE market yet). I set all my synchs (rss, weather) to 4 hours. Others (Twitter) are manual. Only Exchange Email is push.
Using Cpusy & BetterBatteryStats to try to see what's going on. Could be a bad battery - could be that the number I'm seeing is wrong.
Anyway, I'm getting about a 7% drain an hour *with the phone off* ! I'm even rebooting as needed to make sure it's in deep sleep & not 384 (which is very, very annoying). Unplugging the phone @ 7am means a dead battery by 3pm. And if I'm using the phone, it's more like 12-15% an hour (min screen, reading a book). Been charging in the car and at work - whenever I can for now.
Going to try to run some tests on the new rom. Leave phone off for 30-60 minutes & track % loss. Then, maybe put it in airplane mode & try again.
Some weird ones I see to often - Adfree, Maps, Alarm Manager (which I understand can come from almost any of my apps). Oh - tried Juice Defender, no help there either (didn't make any difference at all)
Finally, in the car with Waze (gps), a Podcast Playing, and the screen cranked up for visibility - the car dock/charger keeps the phone about even. On my HD2, a drive to work would charge up like 20-30% of my phone.
Really, really hope I don't need to carry a 2nd battery for days when I can't keep the phone charging.

How often do you get exchange emails? I stopped using push exchange email as it was a huge drain on the battery with the volume of emails I get...
With this phone the screen draws some serious juice, so if your using you phone in the car with the screen on its using about 950mah of juice, so your car charger will likely only keep this phone from losing power, it may not gain any juice, and it may even loose juice depending on charger power and what the phone is doing currently.
This is also why most of us are seeing about 3 hours of screen on time, as while the screen is on its using probably 700-800mah of power. divide that by the 2500mah battery and you can see why...
You can try other programs to try and help with things like background data, undervolting, etc, but that's all going to have a small effect as the "problem" is the screen, its eats up most of your juice. If you want to save battery you need to go after the big thing, the screen, not the little things. However short of reducing the brightness there's not a ton you can do about the screen. It is a big screen, and it needs big power to drive it.

I *think* (need to double check) that the charger is putting out 1A. Where did you get the 950m number from? Is there an appx. chart for different levels of screen brightness (how about 50% for example when in the car? oh - and how much lower is the 5% I use indoors?)
Agree, the #1 thing is the screen itself, which is why I get very confused when I have the large drain with the screen off.
I'll also have to try a test today where I turn on my podcast, but leave Waze off - and turn the screen off while it's charging in the car.

I *think* (need to double check) that the charger is putting out 1A. Where did you get the 950m number from? Is there an appx. chart for different levels of screen brightness (how about 50% for example when in the car? oh - and how much lower is the 5% I use indoors?)
Agree, the #1 thing is the screen itself, which is why I get very confused when I have the large drain with the screen off.
I'll also have to try a test today where I turn on my podcast, but leave Waze off - and turn the screen off while it's charging in the car.

950mah is an educated guess. If you have root you can run this in a terminal to see how much power you car charger is giving the phone... (su first)
cat /sys/class/power_supply/battery/batt_current_adc
I usually get about 9100 for a result, which is 910.0 mah. and my phone will charge barely if I dont have gps going (screen on). if screen is on and gps is on the phone will slowly discharge, so that puts the phone power usage at about 900mah with screen on, so maybe 950 was too high of a guess. So when the phone screen is on, your using a ton of juice for such a small battery.
If I use just a podcast app and the screen is off the phone will charge much faster while in the car. If I have google maps running, it stays almost even...
You could even calculate your usage. She how many minutes your were driving with the screen off and the phone charging and note the amount of battery% gained in those minutes. You'd see a huge difference in charging times with the screen off. In my 50 minute commute to work, I gain about 20% battery charging with the screen off... With the screen on, I see almost nothing.
Seems like some days are better than others.

Will the people that get awesome battery life share what they are running?

I've tried a bunch of different combinations but I have gone back to GB every time. I don't even care about features anymore I just want to get the most out of my battery life. If you are getting great battery life will you post your kernel, firmware, and ROM please? Please post if you are on Ext Batt or not.
Thanks
I have an extended battery and I think my battery life is really good. Primarily, I turn off most automatic syncing and keep my screen turned down as low as possible at all times. I use a widget called Brightness Level and I keep it at 13% most of the time. I also keep GPS, Bluetooth, and WiFi off unless I specifically need them. Other than that, I'm not doing anything special. I'm on Clean ROM 4.5 Standard.

I think the biggest culprit is the screen. I'll get varying battery life every day, anywhere from 2 to 12 hours on a standard battery, or 4 to 30 hours on extended.
The only common factor in each of these for me is screen-on time. I'll get 1.5-2 hours on standard or 3.5-4.5 on the extended battery before it dies.
However, as previously mentioned, turning off Bluetooth, wifi, GPS, mobile data, and sync will always help battery life. Too bad I rely heavily on some form of data, email, and Bluetooth headsets for my work.

All in my sig.
I've got a system...
I usually can get through the day with a regular battery; a few things to remember:
1) Mail/messaging/anything push
if you can deal with it, set peak hours from like 7am to 7pm and get stuff every two hours during peak and every four hours during off-peak. Push means your phone is actively waiting or doing something almost all the time. This one single thing will make the biggest difference, except for...
2) The Display
The biggest energy hog of all. Actually not much you can do here but set it to time out quickly (a minute or less) and set to either auto brightness or remember to turn it down indoors.
3) Audio
Running audio through the speakers also uses more battery. Try headphones.
Bluetooth audio is great but again bluetooth also uses more energy than headphones.
4) Networking startup services
Lots of games install startup services that run constantly in the background checking for data from the mothership and/or other players. Get rid of them or turn them off if you can. Some apps also do this, I dont have a list but a little Googling will enlighten you.
Any other tips? I'm always looking for other (reasonable) ways to save battery.
PS: as you probably know, the phone (and any smartphone) will charge about %500 faster if its completely turned off. Common sense, I know, but you'd be surprised...
this will keep you going all day:

Seriously though, if you actually use your phone throughout the day, its probably better to just get the extended battery. Anytime you turn the screen on, it sucks battery.
You can try juice defender. I have it set to extreme and tell it which apps can turn on data with and without screen on, so 4g is only on when it needs to be.
I've heard ROM toolbox can keep apps from opening in the background but haven't paid for it yet. This would be good for games like draw something and WWF that seem to suck power constantly.
Thanks for the replies. I changed my power from performance to normal and that made a big difference because the phone won't sleep in performance mode. Just a note it will still sleep data even though my hotmail is on push. I am using the hotmail app not the htc mail app. I see people with 3+ hours of battery life in the battery thread and I don't see how they do it. I have the extended and I can make it through a day but I only use the screen for under an hour it seems. I'm not really seeing anything new in here I'm not doing but I do keep my screen auto a lot so I might jack that down. I keep every feature off when not in use.
I'm using stock rooted 3.14.605.5 with same firmware and over been getting better battery life since flashing.
I'm mad as hell about losing unlimited data!

Man, That's some serious ****
I generally get great battery life-around 4 hours screen on, 4g, gps. However, a few days ago I noticed higher than normal temps, and poor battery life.
So what changed?
I traced it to the installation of one free app. Picsart-uninstalled and everything is peachy again.
This is my second rezound, the first one always ran hot and drained the battery.
If you're having problems with heat and drain, run a full ruu and see if it helps, if not you may have a bad device or possibly a bad sim. I don't think that the device is the problem in most situations. More likely a runaway app, bad radio/firmware/build combo, user error, or expectations too high.
My setup:
Latest ruu-cleanrom de 1.4-take it easy on the apps and widgets!

Your issue may lay mostly in poor reception. I notice your signal strength thing is in yellow most of the time. Use WiFi if you can. I get pretty good battery life on
Ineffibilis GB
Feb OTA firmware. Don't remember the numbers.
Dsb 1.1.3 undervolted by about 100mv via incredicontrol (UV depends on the device, each is diff) and under clocked to 1188mhz and with interactive governor.
I think my power setting is on Normal.
Also I have weather sync every 3 hrs. Facebook every 4 and leave my Gmail accounts on sync.
I get between 3.5 and 5 hours every day of screen on time through out the day if I'm using my phone a lot. This would also be coupled with usually around 30 minutes of phone calls too. But usually I only charge it every other day (when it gets to around 30%). I get more time out of it on WiFi (5+ hrs and less on 4G (3.5 to 4 hrs at most throughout the day). I also never run my phone down to less than 20% if I can help it. I'm on stock battery too

That battery life isn't great if you're only using 9m of screen on time. 60% after 5 hours isn't unusual for me if I have medium usage of my phone. Like platinum mentioned, your signal is terrible. The Rezound (and most phones) tend to use a lot of battery if they're trying to constantly find a signal.
Right. Battery should only drop 1 to 2 percent per hour on good signal. Bad signal can kill it... If I was on 3G my phone would be around the mid 90s with the same usage.

Does it matter if I turn off data or it will still drain looking for cell signal?
As long as you don't have partial wake issues, there are only two real concerns for battery.
It's not processor. Again, if the phone's not 'awake' while the screen is off, your phone's processor is not ramping up to full speed at all. While it's on and in your hand, 1.5ghz is a great speed for it to operate. Slower speeds than that significantly slow down how your phone operates, and you will have your screen on for seconds longer (Which uses WAY more battery than the higher clock speed).
In Facebook app, go to menu > settings > and change the refresh interval to NEVER!!!
As of Android 2.2, Facebook does push notifications. You don't need Facebook refreshing very 4 hours (OR EVER!). This wakes up your phone (ramps up processor speed, and so on), uses data (battery), and is unnecessary (since you get push notifications anyway). Turn that crap off. Same with Twitter. Turn it down to manual refreshing only (look in settings > accounts and sync as well as in the app). Same with Friendstream (which will automatically have its own refresh settings - fix them).
There are two things that use your battery.
1 - Screen. Turn your screen off when you're not using it. Stop turning your screen on every 12 minutes to 'see if you have any notifications'. Trust the green LED blinking light, or listen for your phone. You can stop checking it. You're using a TON of battery lighting up that 4.3" screen AND waking the phone back up (ramping up the processor, among other things, and it will stay awake for at least minutes, even after the screen goes back off).
2 - Data. Turn wifi off if you're not using it. Turn Mobile Network (GASP!) off when you're not using it. Pull down your notifications and hit Quick Settings, and turn Mobile Network off. Don't have that? Make the HTC Widget > settings > Mobile network. Turn it off when you're out with your friends after midnight. a) you're not going to post anything reasonable or coherent when you're out drinking anyway to Facebook, and b) call and text still works, so you can still mack on honeys all night (and text them drunkenly). You don't need your damn Gmail at 1am. I know you don't. Don't try to convince me otherwise.
If you keep your screen time to a minimum (and brightness down if you're not using auto brightness), and TURN OFF mobile network (internet) when not using it, your battery will last DAYS. Yes, the stock battery. Now, do you do 100+ texts per day? Sorry, your battery is going to die today. And tomorrow. Every day. The screen time murders the battery, and the Wake time that your phone will have as a result (like every time the phone lights up - for minutes at a time, it'll stay 'awake').
That's how you keep your battery going. On any android phone. Yes, an extended battery works great. I bought one (half price in a verizon store) AND got an EXTRA one for $4 (on amazon.com). Yes, it's for thunderbolt, but YES it's the same part number. It's running my phone right now. Keep it charged, and in your glove compartment. Your life will be better.

Go get it. Turn off your internet, and your screen. Trust your LED notification light. Stop using MMS Screen On. Your battery will last all day, every day. Unless you text a lot. Then, good luck.

In short, yes.
If u turn off data it will help. But you will still have poor signal, so Idk how much it will help. apps and processes that use background data won't be using it, that alone will keep your phone from reconnecting so much, so it will help.
It takes your phone longer to connect on poor signals and your speeds are slower so it takes longer to do the same things. This also keeps your processor running faster for longer times.
