Battery Life - HTC Flyer, EVO View 4G

I just wanted to know what people are getting out of their batteries. I unplug mine around 7:30 am when i leave for work. When I get to work i turn on my wifi (rooted thunderbolt) and leave that on all day. I have the setting to turn wifi off (flyer) when screen is off. When I get home around 5:30 i switch to my home network and by 8-10 my battery is pretty much gone. Is this normal battery life or are there any tricks I'm not aware of that will help with battery. My wife has an Ipad 1 and she seems to get days of use out of it before she needs to charge it.
Also, I don't watch movies or video at work... most of my use is surfing, twitter and email
Thanks

If i charge mine over night, wifi on all day apart from in the evening when it does the power save its lasted over 3 days now, i left it at work but so im not sure what its on at the moment. I use it on the tube to read the news and play angry birds, when i looked yesterday i had something like 4.5 hours screen on time.

Depends on your use. Mine last the day but is only used in morning and night. I usually have 40% or so left when I charge over night

Mine seems to cash out fast. I unplug in morning and don't use until I come home, so it gets maybe 3-4 hrs use and I'm at 25%.

It's difficult to judge battery life, but see this thread. In my opinion, when not doing anything heavy like watching videos or playing games, then a good measure of battery life is how much screen life you have (mainly since the screen accounts for a big battery sink). It's not enough to say that you've used the tablet for 3 days...you really have to specify what you've used and how many hours of each. Because of the difficulty of consistently measuring all the contributors, that's why it's generally easiest to just measure screen life.
From the responses in that thread, 5-7 hours (on minimum brightness) is what to expect from the HTC Flyer.

Check you battery usage stats at the end of the day. There are some really badly written apps out there that will eat your battery if you are not careful. Also, some devices get the dreaded Cell Standby problem depending on which ROM you run.

[Q] Is the TB battery life as bad as it seems?

I just bought a Droid X2, but have decided to take it back for an LTE phone before the change in unlimited data.
I really don't like the way the charge looks, but it seems to be just as good as the TB. The TB has the likely potential to have a better community and better roms.
However I cannot have a phone that cant hold a charge for a whole day. And I do keep my phones for the 2 year duration of the contract, so whatever I get I need to be happy with.
I get the idea that the TB lasts between 4 and 8 hours. Is this a hardware issue, or is it the ROM which would be fixed as time progresses?
It is pretty bad. If you live in a 4G area, you should get the extended battery.
There are some settings tweaks, especially in the stock ROM, that help tremendously. The notification/background data is what kills the battery.
I always get at least 8 hrs with normal to heavy use.
But if your streaming video constantly, yeah like 4 hrs.
Most I have seen is around 20 hrs.
Seems like it always dies with about 4 hours of awake time or actual usage.
In a 4G area. And I think it will get better with hopefully a new OTA.

If you are going to play with ROM's, standard battery life is real bad. I loose about 25% of the battery, 4G downloading, then flashing 1 ROM!
Add 2 hours worth of on anf off fiddling with the screens and setups takes it down to 40% remaining, then I have to turn off wifi, and 4G to get through the workday, ending <10%. If I do 2 ROM's, i'm dead before lunch. Gotta get a cable for work.
Get the extended battery. Mine lasts typically a day and a half with it, moderate usage. Awesome phone.

I can get a full day out of my phone with moderate use (texting, calls, web browsing). I have my settings tweaked and have juice defender running which really helps. I'm on stock ROM and am not rooted, there is a lot you can do to improve the battery.
Well if you use your phone as much as I do then you would be surprised how quickly the Barry drains out haha
Sent from my TB yo.
Mine is usually 60-85% display, and I have it on dead minimum brightness unless I'm outside in the sun, in which case I set it to auto for a few minutes. Mind you, that's maybe five or ten minutes max of screen on time, two or three times a week. On the other hand, a twenty or thirty minute phone call can take ten percent off; I'm one of the people who sometimes remembers that it can make calls, too, so my experience is probably a bit off. I also have most everything set to sync every 2 hours, but I have imo.im running constantly.
If I'm using it pretty heavily, it may be down to 40-60% on the standard battery by lunch, which would be about three or four hours of screen on time. I'm in a 3G area, btw. I just carry a charger; which has the advantage of making other microUSB people happy when their phones die (and we can mock the iPeople with proprietary chargers). Yes, the battery sucks, but every phone has trade-offs.
If you won't have any way to charge the phone (car, wall, etc) during the day, then I don't think you will be happy with the phone. Between my wall charger (or USB cable), car charger, and two batteries (spare is the Seidio 1600 mAh), I'm satisfied.
As for the Droid Charge, the Touchwiz UI compared to Sense is a non-starter.
Is it bad? Yeah, seems like. Is it as bad as everyone is making it out to be? I dunno. I remember a lot of people complaining about the battery when I got the Incredible. With light use (about an hour of internet and email over 3G, one or two half hour calls, and a handful of texts), I'd charge it every other night (and have 30% or so when it went on the charger).
I picked up the Thunderbolt yesterday and charged it overnight. It came off the charger at 7:30 this morning, and I'm showing 54% as I'm typing this at 8:45pm. Since it's new, I was probably fiddling with it more than usual (but not a ton more, as the differences between the Thunderbolt and the Incredible aren't huge).
So with 4G on, yeah, it runs it's battery down faster than my old Incredible. But it seems like I can make it through a day without much difficulty.
EDIT: I figure I might as well mention my settings.
I have the brightness set to about 30%. I shut off any and all vibration. Screen timeout is 1 minute, volume is maxed for everything. Bluetooth and GPS are off (unless I need them). The weather widget updates every three hours. I don't use any other widgets that use data (just a volume profile and a power control widget). The phone can do background sync for my contacts, but my gmail, other mail, and Twitter (Seesmic) are all set to update manually.
I'm getting about 8 hours of moderate usage here as well. I've come to terms with the fact that using a device that is more powerful than my netbook will come with some battery trade-offs.
hey guys,
I'm going to follow this thread for a bit. My HD2 jumped into the Harbor yesterday and will probably be switching to Verizon for my next phone. I'd really like to get the TB, but am really concerned about battery life.
It sounds like people are getting a battery life similar to what I was getting running Gingerbread off the SD card on my HD2...which didn't quite cut it for me on days I was working in the field and not able to charge. But at least with the HD2 I could run WinMo on days like that and not have worry.
Keep the info coming!
thanks

Hello, im currently running with juice defender, but i was wondering if you could help me with what all settings i should tweak to help the battery?
After applying the MR1 OTA update I still wasn't happy with my battery or GPS performance, especially compared to my past phones (Incredible, X, original droid, blackberries, etc)...
After doing a wipe and reloading the apps I use by hand, I have seen battery life match the Inc in 3g only areas, and GPS lock on my location consistently in under 7 seconds.
In mixed 3g/4g areas (where I live), similar results. Battery life and GPS lock are very much improved. And the TB now makes it through the day for me.
In solid 4g areas, well, last night I was surfing the web, reading, looking to see if the GB update for the X had hit. I went to bed around 1 am with 80% battery, didn't hook to charger. This morning at 9 when I looked it had received some emails and auto updated some apps.. battery was at 55% so that is better.
It's still not as good as my droid x, but the TB is certainly more usable than when I first got it a month and a half or two months ago.
The t-bolt is better than my inc was, with bams GB rom I got 12 hours of heavy use with stock battery....my 2 cents...
I just tested my battery life. It was about 2 hours with Carl pagan cosmos on 2g. 4g really eats the battery. After I recharge, I'm going try it over 3g and see if that makes any huge differences.

[Q] HORRIBLE Battery Life due to Display!!!!

HORRIBLE Battery Life due to Display!!!!
Is this because of the qHD display or the 3D?
My display always ends up using +80% of my battery...
I've tried keeping the display at about 25% brightness and auto... both Didnt seem to help...
Any solutions or sugestions?
Thanks in Advance
same as it was for me on my hd2 and my week with the 4g.
just the nature of the beast with a big screen
I was the proud owner of the 4g for one year and granted the display took up a lot of battery it was never more than 40% for me
Sent from my rootless 3VO... Lets get that working
I think it's a bit of a false positive. I've noticed that when I"m in weak signal areas, my display percentage is WAY higher (60-80%) than it normally is. Even when my display is hardly ever on (as indicated by the battery graph). I have a feeling that multiple things (including cell standby/data syncing) are erroneously rolled up into the "display" category.
Dave
The reason you see high numbers is because your display is the only thing that will make a dent into the battery. Everything else isn't consuming as much so that is why you see such a high percentage. My sister has a shift, my dad has a 3D, I have a 3D and an EVO. They all share the same display percentages. People need to stop worrying.
The other apps are not consuming as much power so the display is reading high. I also noticed this with any phone that has gingerbread sense. The shift and EVO started showing results like this once they got the gingersense update.

Is there any way to comfirm this? (app from market?)
I don't know if this will apply to the 3D since it is in reference to the OG Evo, but I find that when I'm on a Sense based ROM it is ALWAYS display that takes up the most, and when I'm on AOSP it's ALWAYS cell standby.

No clue whether it applies either, however that would fit in with Dodgeboy's anecdote about weak signal increasing his display %.

I can say I get 24hrs with heavy usage also, but I am using WiFi. Out of the 24, the phone is active for 6-7 hours watching netflix, browsing the internet, browsing xda, playing fruit ninja and watching videos plus YouTube.
Just cause you don't get that doesn't mean others don't.
Did yall do anything special when u got your phone? I can usually get about 12 with moderate usage. I would love to be able to play games all day with good battery

LOL, there is no way anyone is getting 24 hours out of this battery or their definition of "Heavy Usage" is FAR different from say... HEAVY USAGE.
I'm in sales. I top out around 8K minutes a month making and taking phone calls, in/out pitching , closing etc..
Phone is usually ON - talking, dialing, sending/receiving email, syncing, updating.
I'm lucky to get 4 hours.
lmao.. 24 hours heavy usage.. newbs.

If you charged your battery all the way before using it for the first time then unplug it and plug it back in you will get outstanding battery life and do it every time you charge your phone plus don't drain your battery completely you will shorten life of the battery...quit *****ing and condition your and give automateit a go from the market and turn off automatic brightness
Sent from my PC36100 using XDA Premium App
the bigger the cushion, the sweeter the pushing, if you know what I mean.
I'm on the side that 24hrs of heavy usage being fairly absurd. I'm not outright denying it's possible, but I can't see it.
My phone used 70% over 12hrs. That only entailed receiving push mail for at most 50 messages. I turned on the screen occasionally, but didn't really use the phone. I was connected to wifi most of that time, and had a good cell signal. Estimates say I could get a few more hours out of the phone. That still puts it at around 15-18 hours of almost no use. I could see maybe hitting 24hrs if I didn't touch it the entire time.
Great
I am very pleased with battery life. I'm getting 8 hours plus without any problems.
I have never check to see how long it actually last. I've never just let it run over night. But I have run it about 20 hours on days since I got it and by the time I'm plugging it in at night it still has 30%+ left on it's charge. I run all sorts of stuff during the day, play games, check XDA, use the internet, 4G, navigator, etc., plus spend 3-4 hours on actually talking for work. So, I could believe the 24 hours, especially after running for 20+ hours on days. I always let it charge completely overnight though.
Fully charged on AC overnight. Unplugged at 7:30am. its not even 10 yet and the phone is below 50% charge. i have made two short phone calls and sent a few texts. that's it.
This is pathetic. Even if it is radio related, that's still not acceptable.
Hoping to see the Seidio fat battery get released soon. At least the phone will last a day then
Any thoughts on the OTA perhaps improving battery life? I hesitate to apply it while waiting for root, but from what I am reading, we might be at the mercy of HTC in that regard anyway...
Edit: 30 minutes later, down to 15% charge. amazing.

The Battery on this thing is a monster

I've not been able to drain this thing since I got it a week and a half ago. I have to say that I like to charge things over night. I've not been able to get the Photon below 40% before I go to bed each night.
I hear that you need to drain it full at least once but my habit of charging things overnight is getting in the way. Should I just let it go overnight one night?
I was under the impression that completely draining Lithium Ion batteries causes more harm than good.
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."

Also, i'm sitting at 46% after 15 hours of normal (for me) use. not to shabby. I should mention i'm running Juice Defender and build 4.5.1A-1_SUN-198_5 from the dev. forums and i'm connected to WiFi 90% of the time.
going to try tomorrow without Juice Defender and see how it does. After that i'm going to disable SPB Shell and see if that makes a difference.
Thank you sir. I don't want to root my phone so don't run Juice Defender but I do use the Data Saver in stock a lot. I usually just listen to a lot of music and look for new stuff on FB, check XDA forums blah blah blah, yada yada yada...
I'll not feel paranoid about charging my phone now lol.
Now with my tablet (Acer Iconia A500) I did root and load a bunch of different stuff. This is my first cell phone though and I didn't want to mess with something that I have to pay a monthly charge for. I know I could but it's my first cell phone lol.
How much are you guys using it? For me, I use about 30min talking, 1 hr heavy wifi use, 1 hr light wifi use (reading), 30 minutes playing with settings, and the rest of the day idle...that gets me to about 30%.
I actually thought that is kind of weak. Maybe my battery isn't as healthy as yours? I've only had it for 5 days. I charge it every night.
I use it for about 7 to 8 hours of music, FB updates/posting, checking XDA, about 10 minutes of calls and so far some Netflix watching just to show off the phone to my peeps. Oh and some picture taking.
I am the same way I hate to discharge it completely and its been very hard. I've went a day and a half without charging before it went under 10%. I will say that I am on Wifi 90% of the time as I have wifi at work and at home other than that its on performance mode so no true bells and whistles. I'm thoroughly impressed coming from the Evo.

Average day for me is about 30 to 45 minutes of phone calls, 80 to 100 texts, few conversations on google talk, 30 or so emails on three accounts and i have trillian running connected to two accounts.
Connected to WiFi most of the time, bluetooth is turned on (not connected most the time) and brightness set to Auto.
I really dont see how this phone is a monster when it comes to battery life, I've actually been getting the exact opposite. I just fully charged my phone and after running for 2hrs and 7mins its down 78%.... This phone has yet to last me for the whole day. What am i doing wrong? I dont have tons of widgets and the only app that im running that might pose a problem is Go Launcher

Is that your screen on time? If that is then I would say that is impressive already. When I had the epic on stock if I use it for 2ish hours screen on time. I would need a recharge. (Got a lot better after using custom rom. Around 4 hrs screen on time before recharge)

For the past couple of weeks I've been swapping batteries with an external charger one to two times during the course of a day (plus the overnight charge)... Looks like it's time to do some housekeeping...
Edit: used to have battery life like everyone else in this thread though! While at the climbing gym last night I noticed that the thing felt like it was about to catch fire against my thigh - it had burned through about 60 percent of a freshly charged battery in about two hours. I have a nagging suspicion that I neglected to uninstall something (or a few things), and now something non-existent is constantly being polled for as a service after I launch some app for the first time...
when i got my phone it did great on a full day charge, but now with it just sitting at the office its at 70% by 11am i take it off the charger 7-8am .. it started to "weaken" after i downloaded a ton of apps i leave wifi on and 4g off but it also depends on your signal strenght at home it will kill the phone halfway thru the day because i have one bar

[Q] Rezound Battery Usage concern?

I just received my Rezound new yesterday, downloaded some apps from the market, and set everything up for normal use today. I got it off the charger this morning around 7:30am at 100% and its dead at 4:30pm. I would consider my use light today as I only used the web for maybe 10 minutes. I mostly did things like add contact shortcuts to my home screens and move icons around, and download maybe 2 new apps.
I came from a Droid 2 which got pretty awesome battery life running Liberty 3 and I'm wondering if my usage time is normal.
Total Time 8h 22m 33s
Display 80% (Time on 2h 45m)
Call Stand 5%
Phone Idle (Time on 5h 37m)
Android System 3%
Dolphin Browser 2%
Android OS 2%
Wi-Fi 2% (Time on 1h 38m)(I don't believe I was connected to any networks though)
Drop box 2%
The screen is what kills it along with LTE. If your screen was on for 2:45 that is why. The display sucks battery on this phone.
Thanks for the reply, I figured that was the case, but I still thought I would have gotten a little longer. I hope a custom ROM will help some with the battery life.
I am on stock rooted and don't really have battery issues. Typically I get 12-14 hours which by then I have easy access to power. If it is going to be a long day, I use the extended battery. It is not uncommon to still have charge left going into late at night.
I have the screen less than a third of the way on the selector and have Auto brightness turned off. Screen timeout is set to 1m but when I set the phone down, I have a widget called ScreenOff that I click to blank the screen. Primary reason for doing that is so I don't accidentally enter some app, but a secondary is that it turns off the screen before it would normally timeout.
When I am at home or at work, I use WiFi almost 100% of the time which due to strong WiFi signals there, (for me) uses less battery power than LTE.
Otherwise, I have LTE on.
Right now today, I am about 50% with 9h 12m of use. I fully charge nightly with the AC charger on my night stand so when I get up it is 100%.
I have an extended battery, but normally use the stock battery unless I know I am going to be away from the office for long periods of time.
I am not much of a game player, but I do watch short videos from time to time. I have streamed music, but don't normally. I get 10-20 calls a day typically and use my browser on a regular basis (reddit as well).
The camera is Awesome!
Unless your display was on max brightness and you were streaming HD movies. That's bad battery life. I get 2 times that even with autobrightness, maybe your battery isn't broken in yet
A good measure is 30minutes display time per 10%, and 1% per hour with 3G and normal sync scheduling... If your apps sync ever 15 minutes that will kill it, and 4G should kill it a little more than just 3G... Minor fluctuations are still OK, but you shouldn't have 15 minutes per 10% unless everything is basically on full blast
My battery life using the setup in my sig is usually very good.
I can easily make it through a normal workday listening to mp3s from my card/texting etc using the standard battery. My screen is set to 30%, screen timeout to 30 seconds.
I do like to stream audio however using iheart radio or Sirius radio online. If I do that, I'm lucky if I make it 4 hours on the standard battery (without ever turning the screen on) When I am going to do that, I use the extended battery and keep a 2nd one in my pocket. I have two external chargers I use so I always have spare fully charged batts.
I actually prefer the feel/weight of the phone with the extended battery and the HTCPedia cutout hard rubber case.. That gives me a better grip on the phone and I barely notice the weight difference when it is in a Jean pocket.
I guess it just depends on the actual phone itself. My phone charges everynight. I pull it off the charger at 6 am and by 10am the battery is dead. I have 3 batterys, and a wall charger that I carry around. I don't consider myself a heavy user either. No music or videos. Only text, gtalk, gmail and a phone phone calls that last a few min each. I only have google and exchage set to push. My 2 yahoo accts sync every 4 hours. I do have fecebook as well. Screen is very dim. This was all using rooted cleanrom.
I am now back to bone stock, with a CLNR phone that just arrived yesterday (due to connection problems with my computer) So maybe a stock rom unrooted will make a difference. Heres hoping!
Sad.....great phone, I love it!

This. I was playing "draw something " with friends today at work and even with a fully charged extended battery it only lasted about 3.5 hours with the backlight at 100% and oc'd to 1.7 GHz. But that was constant usage for those three hours.

Diff. Roms equal diff results for me. All of the ICS roms I've tried all keep my phone up time and awake time the same. Is anyone else having this issue? Due to this, I typically end up getting around 5 hours of life even if I leave my phone off for the duration of that time. It's annoying because I really want to stay on ICS but get double the battery life out of the GB Roms.

On Scotts CleanRom 3.6, with fairly heavy usage (hour of solitaire, hour of browsing xda, texting, 30 minutes of phone calls) I can get about 10 hours before needing a charge again. Before I updated to 3.6, which has the 3.8v battery fix, I could only get about 5 or 6 hours of similar usage. I don't recall if prior versions had my awake and up times the same, but I haven't noticed it recently.

I take it you don't stream audio like I do??
I just got my Rezound yesterday, and have noticed a surprisingly poor battery life. I did all my setup yesterday, and fully charged the battery over night. After unplugging it this morning, I listened to music off the sd card for about 45 min, browsed the net for about another 45, then stopped using it for a while. I noticed the battery was about halfway through, so I plugged it in to my car charger and did some more Internet stuff. However, after checking the battery info, I realized that even plugged in to the car charger it was consuming more power than it was taking in. I finally had to turn it completely off and let it charge to get the battery from yellow back to green.
This is the same charger I used for my Droid X, so I know that it is working...

I've been running BAMF ICS v0.9 for a few days, and the other versions before that. I get 12-14 hours with 4G on, and 20-23 with 4G off....I keep the screen on 40% brightness
Watch your clock speeds if you are on ICS. They constantly Max out, both cores. That's where your battery life is going.
Sometimes data flickers for me on random days, that's the only thing that wears my battery down fast. But I can still go through the day have 40ish percent left. If it doesn't flicker I can go through through day with about 50% left. And if in on Wi-Fi most of the time I have nore than that left over. And that's with using the phone for a couple of hours with the display on.
Trying ineffabilis with DSBs 1.1.3 kernel and undervolt it some
for me, battery life killers can be streaming audio (sirius xm or espn radio) and definitely jelly wars. Phone will die on extended battery in about 4 hours of continuous play.
Otherwise, normal usage, I get 10-16 hours of use on my extended battery before swapping it out (use 2 extended batteries).
4g definitely runs the phone hotter than wifi (about 20 degrees hotter for me)
The only time my phone gets around 95 degrees is if it's on a charger and I'm watching a movie, and it takes about an hour for it to feel warm, which could even be caused from me holding it the whole time. 4G doesn't get my phone any hotter than 3G Or Wi-Fi. Guess every phone is different though. least we get signal xD

Thought I was done with heat after I got my replacement phone but the 4G hotspot Cooks! 120 is now a daily ordeal.

Battery gets literally 4 hours before it's dead

I ,am on it a lot, between GPS and general usage, ,but this still seems like too fast to drain compared to what others here have said. I had this problem with my Atrix too, maybe i am just destined for bad luck with battery life
Do you use anything like juice defender. This app literly doubled my battery life!

Apps like that only increase standby battery life. Everything else is very minimal.
And I'm not happy with the battery life either. My phone is plugged in right now and the battery is actually going down as I use it.

This happened to me since i first got the phone it has slowed down and now the phone can last through the day ever since at&t throttled me for this month goes without saying ill take it easy next month. so most likely if your in an lte area thats the problem

If it's notbthe stock charger you areblikely not using a rapid charger.
Sent from my SGH-I717R
I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.
I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.
FYI I don't have LTE, but do generally have good 4G.
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.
Most people get about 5hrs screen on time. Total on battery ranges up to about 24hrs, but only if the screen is off at least 19 of them.

i can get about 3 or so
5 hours of screen time AND 19hours standby sounds incredible
would sure like to see screen shot as well
and def dont think 5 hours is any type of avg
I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.
On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

Was thinking of doing that since they're so cheap but thanks to juice defense I don't really have that issue no more.

I had a ss of my buddies yesterday, but can't restore mms lol. There are plenty of other ss in the note section. He was at 22+ hrs with about 4:30 of screen on and some % remaining. I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.
If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.
Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.
A couple things to note after seeing a few of these posts...
BT can be on, but without it searching, connected, or listening it's not active.
GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is
1) Charge you phone until it says "charged"
2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)
3) power on phone and let boot and than power off and wait till you see 100% again
4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this
5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go
I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with
You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.
I get 15+ hours and do not any battery juice defender apps

Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.
IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

Hour? Hour and a half? I'm working during that period. I usually hit news sites and G+ when I'm first at my desk in the morning, so that's 30 minutes or so off and on looking at it, then perhaps an hour over the rest of the day, sometimes more at lunch.
I'll look closer today and post back.
