Battery is Great on the Tunderbolt

Put it to a real test. Went to the grand prix today in st. pete.
Didnt even have a full charge around 90%. Had 4g on all day.. Brightness all the way up. Facebook , twitter, and 2 e-mail accounts running in the background. Took tons of video clips and tons of pictures, and streamed music through the bluetooth on the way home. As I type this its been 10 hours since it came off the charger and its at 50% battery with all the same items running.
At 1st I had very very bad battery life. But after using it for a few days and then doing a battery pull (read it would get better after all this) it has been working great, with the same or more use then I was doing the 1st few days of ownership. Just wanted to share a postive experience on battery life since I keep hearing and reading so many negative things.
Edit: Thunderbolt not tunderbolt LOL

Thanks for the tip.
I'm noob w battery. Do you mean just charge it full, pull it out and put it back in and it lasts you that much? I'm skeptical....The most I could have so far is 12 hours and I have 3 bars (out of 10) left.

The main reason people are having drain on 4g from what i heard was the software for the radio was re-written at the LAST minute (the reason for the delay) because they had to change their 700 MHz frequency just a bit higher.. something like 5 or 10 Mhz due to interference with with communication towers at airports. this sucker keeps dropping 4g like its no ones business. the new baseband which will be pushed out in the first update for the phone (hopefully in next month) should correct it.

Thats funny because i was at the gp today and my battery died before i left at 1p. Took a couple of pictures and 1 video. Used gps for like 10 mins and that was it. Stayed in my pocket for the rest of the day.

hmm
I Disabled my 4G with dialing the *#*#(forgot the 4 numbers)*#*# and my battery has been lasting me alot longer

I'm in a 4G area so I have the phone set to LTE mode only and I get great battery life.

I probably have the worst battery life ever... 70% before putting it away and not using it. 5 hours later, I check my battery and I'm at 10%!! I didn't even use it!

my battery was about to die on me today within 3 hours of being off the charger, granted it was with heavy use.. flashing multiple roms using titanium backup etc... but i still think that is asinine..

flashing roms will eat battery...once you are on a rom it takes a cycle or 2 to settle

The battery life on the TB is just as good as it was on my rooted dinc with a custom kernal. I have no complaints with stock unrooted TB so far and I use the **** out of it.

I turned off 4g and am going 16 hours on 50% battery. Really, to sit in my pocket, do calls, text, and check email I don't need 4g. I too noticed the 4g radio switching on and off constantly. Hopefully the baseband update will fix this.

It has more to do with where you live and how good your 4G coverage is

i get 12hrs easy with moderate use. All I've done is turn off the GPS services when not needed and disable the lock screen... hope things improve for everyone having issues... :/

What do you mean, is there a special way to charge it now?

I think he may be referring to the "bump" charge. Where you charge the phone to full, unplug it, turn it off, charge it to full again, unplug, turn it on, and charge it to full again. Not sure if this is an HTC thing or just a general lithium ion battery thing. But it helps IMO.
I get about 12 hours of battery life with moderate use. I little web surfing, lots of texting, light app usage. My phone is constantly switching from 4G to 3G when I'm indoors. Outside though I'm fine. I'm surprised about the different experiences people are having with battery life.
Since I can't get through a whole day without it dying I bought a second home charger on amazon. I'd like to get the extended battery, but it looks like it'd make this phone too big at that point. I wish there was some better battery tech coming out soon, since there hasn't been too much progression on that front.

Turn on the wifi radio. When you are home or anywhere you have access to wifi, the device will automatically turn the 4g radio off when wifi is up. That simple change has made a huge difference and I dont have to worry about turning the 4g radio on/off manually.

I've been seeing, under heavy use, at minimum 8 hours of use consistently since I've been through a few cycles, including bump charging the first few cycles. Also, a few things that greatly helped me:
Read somewhere that the stock blockbuster app, even if it has never been opened, has a service that updates the movie catalog in the background. Run the app, update it, and in settings turn off movie catalog updates. After doing this my battery didn't drain nearly as fast while in my pocket. I can't verify that this actually helps, but it did for me. I disabled the 4G radio since I live in a 3G area as well.
I also run Green Power as of this morning. My phone has been running over 12 hour with 3:30 of that being actual usage and I'm at 68% remaining. I have it set to 1 minute on and 10 off for data while it is locked in my pocket.
Beyond that, GPS is disabled unless I need it. So is WiFi. Brightness is at about 30%, with a widget to bump it to full when I'm outside in sunlight. I also noticed a big jump when I disabled HTC sense Facebook updates, and used stock Facebook instead. Every time I went to contacts it would download that contacts Facebook updates, which is pointless and uses data constantly under normal usage.
Of course your mileage may vary, but this all gets me through the day under normal usage, and over a half day under heavy usage.

I am currently at 8.5 hours with 79% left on my battery. Stock Battery. If I didn't have to work tomorrow, and be able to make phone calls and such I'd leave my phone unplugged all night to see how long it can go.

I'm assuming thats with Virus Rom as it says in your sig? If so, that makes me want to try it. I'm stock unrooted right now, haven't had time to invest in rooting the ADB original method yet, don't want to rush through it. When I do, I fully intend to try that rom out.

Battery issue?

Purchased this morning and the battery was drained... Fully charged at 5:30pm. Now at 7:30pm im as 50% with minimal use. a 4-5 hour battery life is not going to cut it.
Hopefully this is just an initial charge issue, but my vibrant never drained this fast.
Worried!

U may actually have a bad batt. But id give it a chance. Drain it down to 0. Turn it back on. Let it die again.
Then charge it while off. If it happens again youll know.

I have done a few charge cycles completely draining it and battery life is still pretty bad...it better get a lot better than this or it is going back.
Also getting random freezes and reboots.

I've got a ton of apps and widgets installed and use Exchange push. Battery life has been just a little worse than my G2. The phone froze after I first configured it and I had to do a hard reset and rebuild it. It runs a lot better after the reset. You might want to start-over and see if it make any difference for your freezes and resets. I'm purely guessing it may be the difference between the phone configuring the SD card and reading off of one that's already configured.

Bad batt. 4 hrs is a wayyyyy bad.

Sounds like my experience too. My battery yesterday lasted me no more than 7 hours. Wooh, I was pissed. So far today though, It's been on for 14 hours and I'm only down to 25% with some medium-to-heavy emailing and texting, and a few 5 minute phone calls. I'm very impressed after this second charge. I'll drain it again tonight in hopes for a little additional life. Stick it out for another day or two, OP.

I'm really concerned because I've had my phone since Monday and have charged it at least twice a day. It's not getting any better :-( I have even froze alot of the bloatware and apps that run in the background. I can't handle 6hr battery life :-(

You mean for an exchange? Or ask for a new battery? Will they do that?

I also have serious battery issues. The battery usage is mostly consumed by cell standby and bluetooth. On my mytouch 4g at most these parameters were a few percent each. On the g2x they are like at 25% usage each. This does not appear to be normal. This is with minimal to no usage. I dont get it. Is it a software issue, there is no reason cell standby and bluetooth should be usaging so much juice with little to no use.

Root your phone, after that install Titanium Backup from the market, and once you load titanium backup, you can actually go to Backup/Restore and find the app that you want to freeze, click on it and choose Freeze.
Once you install Titanium Backup - it will ask you for root rights - click on "yes" or "allow" (dont remember exactly which one it was" so you can provide root rights for it.

Anybody know of documentation on best way to calibrate the battery? I did 1 discharge - charge cycle... how many more do I need to do? Do they need to be back to back or can I keep it plugged in while using it today?

My battery lasts a little less than my NS or vibrant. It should at least give you 5-6 hours of HEAVY usage. I left the house yesterday at 10 and by 6 it was done. Since it's a new unit I used it heavy, plus I rely on it for scheduling and contacting clients about every 30-60min. I was also playing games on my breaks.
You probably have a bad battery.

I do seriously think that there are a lot of improvements that will come in a software update. The Cell and Wifi usage are ludicrous and it's probably a matter of getting the phone out the door with an update to follow.
This is only the second Tegra 2 phone to be released in the US.

2nd day with the G2X and the battery life isn't getting any better... If anything it's getting worse...
90% at noon and 20% at 2:40pm. Plugged in at 2:40 and now 20 minues later im back at 88%
Drains way too fast, and seems to charge even faster...
This phone is faster is every way compared to my vibrant, I just wish this wasn't true for the battery loss..

Battery draining AGAIN

So i tried what you guys suggested. I rooted the phone, bought setcpu, using anttek to freeze running services, and used the battery calibration app still NOTHING. I just woke up and my battery was at 0 before i went to sleep it was at 62%!! How can it die in idle with no running servislces wi fi off gps off BT off i mean it has to be the battery right?

This may or may not be related...just something to think about. For years I've placed my phone in the top drawer of my nightstand when sleeping. What I noticed when switching to Android is if I leave syncing on it will drain my battery. My theory is...in the drawer my data signal is very week or non existent. The phone dutifully tries to sync on that weak signal...searching for signal...fails and retries...or succeeds and transfers at a snails pace. Result dead battery. I've found that disabling data before bed results in less than a five percent drop. Just my experience.
If not then I'd suggest a phone swap.
Also...Why in the world did you start another thread? If we scatter all these x is wrong with my phone posts across multiple threads it really hampers the effort to solve the problem.

Yes. Like the OP, I tried the solution of the person that is so called getting 20hr battery life under medium usage. Just doesn't seem feasible at all. And its really annoying to have to cut the data off completely to keep the phone from getting warm...

If you researched the problem and tried the solutions offered, then the logical next step is to contact T-mobile for a replacement. This is an early release of a new phone; there will be defects. And you don't have to settle for a defective device/battery. I can assure you, I get battery life on par with my previous phone (8-20 hours depending on my usage)..so, bad battery life isn't a problem inherent to the phone. And my phone doesn't get warm with data usage. It sounds like you might have a defective battery or phone. If you aren't satisfied, don't settle...make 'em make it right.

I get about 5-10% battery drain overnight most nights and I am not mindfull of what apps are running or what is on. My experience obviously differs from yours. I do get great service in my bedroom where the phone is overnight. The other night I did experience a bout a 60% drop when I left the phone in my daylight basement (underground). I get crappy 2G service in my basement and it looses signal a lot. I think it adds some credibility to the searching for service slowly killing the battery. maybe try putting the phone in airplane mode before going to sleep. That should give you some indicator.

I'm now are 28 percent after 3 1/2 hrs with the display only using 13% if that..

Just curious, does your phone feel hot right now?

You might have a bad battery or something. My first g2x rebooted constantly and drained the battery and got hot.
New one goes 8am to midnight with 20% battery left, on moderate usage. And even at the 20% left i can leave it overnight and it'll still have power in the morning.

The phone is going to get warm is use because the CPU is under load and that produces heat. As long as its not overheating this is normal.
Have either of you tried the factory reset? That fixes the idle drain for most people.
Also... Your phone is going to drain battery faster while actually in use no matter what you do. The LCD and data connection are the biggest battery drain for smartphones. Until battery technology improves, there is nothing that can be done about this. But like I said try a factory reset and you should see your idle drain improve dramatically.

Were you on wifi? Because if you weren't that much drain is within the norm. Web browsing = constant data connection = more power consumption = faster battery drain.

I had 10 hours of heavy use yesterday and had 25 percent left... 2.5 of those were in airplane mode cuz I was flying from Phoenix to Atlanta but I watched a movie during the flight and had music playing the rest of the time... during my layover which was 4 hours I browsed the web, watched a stream of the Celtics vs heat for a bit, more music... I plugged back in with 25% left and had 3h20m of screen on time... this battery is freaking awesome! I had drain issues initially but they went away and now I'm golden

when i did a factory reset, my phone was getting hot until i remember about the *#*# thing and changed that to wcdma/gsm auto. then my battery life got better.

Battery Drain is mostly Cellular radio
I too am have been looking for a way to have this phone last at least 8-12 hours with normal usage, but I don't think its going to happen unless there's some major update to the radio firmware coming in 2.3 Gingerbread..
All the evidence seems to suggest two culprits... for battery drain.
- First is the 4G radio, look around at almost ALL 4G enabled phones (whether on GSM at&T Tmo or Verizon), all eat your battery, from the very beginning EVO 4g, Verizon Thunderbolt, Mytough 4G every single one of those phones has the users complaining about horrid battery life. You can confirm this by looking at the battery usage on the G2X and you'll see that the number one use is Cell Standby (that's the cellular radio) on my phone its anywhere between 35% to 60% of total power used.... on kmy nexus one it used to be the display.
-Second, Tegra 2 is more power hungry , granted its a mobile SoC but its mainly designed for Tablets and such with beefy batteries, this is the reason that the Atrix comes with a 1950MaH battery, you can try and use SetCPU to lower the speed, but I have had minimal success.
Here's a test , when you don't need your phone put it on Airplane mode, for 24hours and watch HOW LITTTLE the battery drains.. reason the cellular radio isn't on..

I agree. These battery threads are driving me nuts.
Go in the other million threads and read

The thing that is strange to me is how quickly these phones charge. It seems to go from 0% to 100% in well under an hour. Was thinking I should try charging it while off (well, screen w/ battery only).

What???? Having the phone on makes my battery drain? WTFO?!?!?!
Seriously though, I have not experienced bad battery life on this phone. Last night I left my phone off the charger, gps, wifi and wifi calling on, and when I went to bed at 1030 I had 64% battery. At 700 this morning I had 54% battery. Only a 10% drain for me overnight, or a little more than 1% per hour.
All I've done to achieve this is the following (and I realize that supposedly you no longer have to condition Li-ion batteries):
-when I got the phone, I didn't charge it but instead let the battery die completely to where I couldn't even turn the phone on.
-charged the phone overnight w/o turning it on.
-let battery die completely again.
-charged phone overnight w/o turning it on.
-let battery die completely again.
-charge and use phone normally.
I've also rooted the phone and used Ti Backup to remove most all of the bloatware except wifi calling, but otherwise it's the stock rom.
I typically get an entire day of my normal use on this phone. If I use it alot, I have to top off the battery w/ my car charger on my way home from work. This isn't unusual. I had to do this w/ the blackberrys I owned and my evo when I was on Sprint. The battery life doesn't seem any better or worse for me than any other smartphone I have owned, and it's certainly better than my evo or my wife's evo, and both of those were rockin' custom roms and uV kernels.

Battery Life, Oh?

I think it's crazy how many people are downing the battery life on the Sensation. I used my phone a bit today. Off the charger at 10AM, used GPS to go to work with Bluetooth activated as well. Forgot to turn them both off while at work. I used my phone like ever 5 minutes checking Twitter updates(also weather/news/facebook/email/etc updates are automatically updating as fast as the app allows. So quick updates for all my apps, GPS and bluetooth turned on all day. Home around 5, watched a few episodes of South Park on Netflix with my phone. Read some news. Played a few different games for about 5-10min each just trying out new games. It's now almost 1AM the next day, and I'm above 40% battery life. I manage my screen brightness, that may be the only thing I remembered to manage well today. While outside/in car, full brightness, inside, as low as possible.
It's shocking to me when I see threads of how the battery life stinks. I'm using the stock battery, I don't even seen the need of getting a larger battery because this already gets me through a day full of activity. Anyone else find the battery life on this device, quite handy? Mine is rooted, but it's stock ROM. I'm also using a skin posted by a member of our forum, the transparency. I'm running the stock T-MOUS(why is it called tmous..? are people that lazy to spell out t-mobile?) ROM, because I accidentally deleted a few apps I discovered I needed back, and did not do a backup. Oh, and I'm also using the battery mod, for the battery icon in my notification bar.
I guess I'm just praising the battery life, is all

I have only had my sensation for about 5 days and battery life is amazing! Im still stock too.. I came from an evo 4g rooted running cm7 and or miui and battery life doesn't come close to being as good as my sensation. Not only is battery life awesome, this phone is awesome. I moved to Southern California a couple weeks ago and Sprint out here is horrible.. so I switched and couldn't be happier. Plus I like this phone was better than the evo series. Battery life is sweet!

You would have to post a screendoor shot of your battery usage and screen on time to completely determine how much the phone was used and how long the screen was on.
Bluetooth and GPS don't use any battery or have low usage (depends on the chipset because some completely turn off) during standby since they're not being used at all.
So we can all praise our phones for having good battery life, but it all depends on usage. If you don't use your phone a lot (you could turn on your screen every 5 minutes but at the end of the day have only like 45 minutes of screen on time and like 70% battery left.) Then you get good battery life. Use your phone a lot and quite simply battery life sucks.

I think it can largely depend on how you use your phone, not just how often or for how long. For example my Fiance also has the Sensation and on her first charge she got 3hrs52minutes before hitting 10% battery. Since then she has only gotten ~2hrs each day now that she has Twitter and Facebook for Sense accounts set up.

That's not good. There's gotta be something wrong with either her phone or something. 2 hours of battery life warrants an exchange.

The phone lasts longer than 2hrs, that's 2hrs of the screen being on. my sensation get's about the same. This is with Gmail on Autosync and Twitter/Facebook for Sense accounts enabled too.

If I do what u did, my batt will be flat in 6 hours. Somethings just not right with my sensation.

I manage my screen brightness, that may be the only thing I remembered to manage well today. While outside/in car, full brightness, inside, as low as possible.
It's shocking to me when I see threads of how the battery life stinks. I'm using the stock battery, I don't even seen the need of getting a larger battery because this already gets me through a day full of activity. Anyone else find the battery life on this device, quite handy? Mine is rooted, but it's stock ROM. I'm also using a skin posted by a member of our forum, the transparency. I'm running the stock T-MOUS(why is it called tmous..? are people that lazy to spell out t-mobile?) ROM, because I accidentally deleted a few apps I discovered I needed back, and did not do a backup. Oh, and I'm also using the battery mod, for the battery icon in my notification bar.
I guess I'm just praising the battery life, is all

Oh! Makes sense..
But 2 hours with screen and dead in 6 hours? I'm glad I have a G2x then. Cause I get 3 hours and like between 13 and 16 hours.

The phone lasts longer than 2hrs, that's 2hrs of the screen being on. my sensation get's about the same. This is with Gmail on Autosync and Twitter/Facebook for Sense accounts enabled too.

You can go by statistics and on screen time and what not. but I just got home from work, and I literally used my phone for about 2 hours straight calling carriers for a customer. I'm above 80%. So from 9AM-4PM, only saw a 20% drain. Once again, keeping BT and GPS on just to see how it goes. ALL of my autosyncs are once again, on, and set to the most frequent can be.
Compared to any other stock phone, this is amazing. Compared to my Cyan N1 and my Cyan NS, it's not a huge difference. Although, at this rate I may give the lead to the Sensation, since I'm leaving all these extra features on throughout the entire day.

good
I get two to three days out of my Sensation, and I'm a relatively heavy Internet user... don't phone much.
At first I wasn't getting great mileage - having to re-charge after only 10 hours or so, but did two things to improve it dramatically...
First, charge the battery once using the following method:
1. charge battery to 100% and leave on charger for an extra hour
2. unplug the cable, turn off* the phone, and plug the charger back in. leave charging for another hour.
3. unplug the phone, turn it on for two minutes, turn the phone back off*, and plug in the phone again. leave charging for another hour.
* when I say "turn off", I mean completely, without fastboot. so either disable fastboot before switching off, or turn off the phone and pull the battery then put it back in.
Second:
Turn off automatic screen brightness, and set the brightness manually to what you need. Ideally, I'd like to have an auto-screen brightness adjustment that automatically sets it, say, 25% lower than what the built-in function does.

That's pretty exceptional. I usually get 13-14 hours with 5+ hours of screen time before I'm at 20%. Using the chichitec battery, btw.

My chichitec battery went 18 hours yesterday before it got to 10% and I charged it. That was with a lot of web browsing, some phone calls, music, games. Id say, medium-heavy usage.

Same here I have had several Android phones with different carriers and this is hands down the best, on par with the iPhone I had previously with Verizon. No problem getting through the day with Exchange and 2 IMAP accounts and heavy phone use, the only mod is I set screen brightness, battery is stock.

no one is complaining i watch sparticus on netflix and game of throne on hbo go for 5 hrs straight while facebooking random hoes . and i am out of battery..
we are complaining that the 4g drains the phone while on idle.

this is the best battery life i've ever had on a phone. i can't complain at all... i even have gps on and i could never do that before. lol!

Guys, having GPS on doesn't use any battery. It only uses battery when it is active. So for most of you 99% of the time your GPS is off aka standby or whatever you wanna call it.

One reason many people complain about bad battery life is that it seems some Sensation models are actually faulty. Best evidence: TechRadar review.
http://www.techradar.com/reviews/phones/mobile-phones/htc-sensation-943466/review?artc_pg=9
UPDATE: We've finally managed to get our hands on a new review model of the HTC Sensation, and the good news is the battery life is definitely improved.
It seems that a combination of data-hungry applications and a slightly dodgy model caused the odd readings from before, although we're not entirely convinced the above scenario isn't one power users will face, which is why we've left it in.
But in normal use, and by that we mean sending 42 texts, spending 49 mins on the phone, watching an hour and bit of video and using the music player constantly, plus a few minutes spent using GPS to track ourselves and browsing the internet for roughly 45 mins, the battery pretty much lasted the day, although it was often in the yellow zone come 11PM.
However, what was more impressive (and a relief) was the sleep state of the HTC Sensation. Where before the phone would get very hot and start spewing out battery life in our pocket for no reason, if you leave the phone locked up for around 10-15 minutes on our new model the power consumption dropped to almost nothing.

"Hypermiler" (Battery Life) Tips

This is a little bit of a boast, I guess you could say... but also educational in a way.
This is my most recent battery life. I found that when I posted my screenshots, people think they are faked in some way. (Posted it here and other GS3 forums) They are not. I am using the stock battery my phone came with. NOT an extended battery. And you can see from the battery graph that the phone was not charged. I guess this is to show that you can use your phone heavily, and still get amazing battery life.
I am using the stock jellybean leak. Not rooted or unlocked.
This is everything I have done to get good battery life.
-I turned the LED touch lights off (I don't like them, they're so bright)
-I have all vibrations off. My phone does not ever vibrate.
-I have power save on.
-I have S-Voice "wake command" off.
-I have motion control disabled.
-I am almost always on wifi (work & home)
-When I am on wifi, I turn mobile data off.
-When I am going to bed, I put my phone in airplane mode.
-I rely heavily on the task manager, I clear my open windows and under the "RAM" tab I clear memory. Probably once an hour.
-I have my sync OFF. I check my email manually.
-Auto brightness.
-I never partially charge. I let my battery go all the way down to 1% then I charge it to 100%. Always.
-Always have a dark background, if possible.
Thats everything. Mind you, I didn't make or receive any phone calls on this cycle. But I did use my phone, as you can see I didn't just let it sit around. Device idle was like 3%?
Anyone else a "hypermiler" like me? I don't get this much screen time every time, it ranges from 5-7. I've gotten more than this and I've gotten less.
Hope this can help even if it's only a little.

-Clearing the ram too much actually drains the battery more because certain apps will have to auto start again every time you clear memory
-Keeping it at around 0-30% all the time should save you more.(I can still see my screen during the day at 30%)
-That doesn't do anything.

-Are there no A/C outlets in your bedroom?
-What the previous guy said, this is a stupid thing to do. Java was designed around efficient use of resources, and restarting running apps (which would happen, unless you have them removed entirely) would use more processing power than you had saved by not having the tasks running in the first place.
-Using Auto is causing the system to periodically poll the light sensor, draining more battery than used otherwise.
-This is how you kill Li-Ion batteries (one way, at least). The whole spiel about discharging fully, THEN charging fully or the battery will have some sort of "memory" of capacity less than actual capacity is how Ni-Cad rechargables work, not Li-Ions. Li-Ion batteries are the opposite. For superior life, keep them topped up as much as possible. FYI
I hope THIS helped, more than a little.

There are plenty of outlets in my room. Lol I just don't need to use them that often as you can see also I hate getting calls and messages in the middle of the night but I use my phone as an alarm sometimes so airplane mode just seems convenient.
This is just what I do. I mean, some of the things I do may not help at all. But this is what I do with Android phones and I've always gotten really good battery life. I've always, always gone down to 1% then charged up to 100% and I've never had a battery go bad on me. Then again I only ever keep a phone for 1 year. I do know that these batteries don't have the memory problem, I just can't bring myself to not fully discharge or charge. I have mild OCD, for real. Little things like that brother me
I'll play with backlighting to see what that does for me.
I've gotta be doing something right. Idk about the task manager, I've just always liked not having programs running if I don't need them to be. I know they arent "running" but it just gives me peace of mind, I guess.
Thanks for the recommendations I will try them.

You getting really good battery life =/= you getting the best battery life possible.
I have pushed ~2 days of battery life without charging many times on my GS3 (with all the bells and whistles running, just mobile data turned off when i'm not commuting), i just don't have a reliable measurement because:
1. I'm flashing mods/roms/kernels/whatever multiple times per week, and
2. I usually charge my phone when it's convenient, which is fairly often.

I stopped flashing because of my OCD. I mean, I'm not crazy but it causes perfection issues and all the ROMs I was flashing had glitches here and there and Idk if you've known anyone with OCD but with the perfection issue, those glitches were all I could think about. So there went flashing. Lol.
Also comes into play with the charging thing. You seem knowledgeable in what you said but even though you said keeping it topped up is best, in my mind, that's destroying my battery. Lol. I really do appreciate your info though.

I'm glad you said it, so that I didn't have to. :silly:
I read your post and the first thing that came to mind was, "there is medication for that, you know.":laugh:

Here's my .02. My battery never lasts that long. Not even close. I'd feel disappointed if it did. I bought my gsiii with the intent of gobbling up unlimited data and using the oc'd processor to run apps till the phone is so hot I have to set it down. I've burned up almost 6gigs of data since the 7th. I get around 4 hours of screen on time most generally. I also throw it on a charger whenever I have the chance. My battery rarely dips below 50%. Like others have said, full discharge cycles are for ni-cad batteries. Li-ion doesn't benefit. Good battery life for me is the lg flip phone we have on a diff line that lasts a couple weeks.

Okay, okay, as long as you admit it... I'll stop being a snarky jerk. I'm totally the same way though. Perfectionist to the core.

It's a very bad idea to let the battery go down to 1% regularly, lithium batteries should be charged more often for better life and more cycles

Sorry but I still just don't believe 7 hours of screen on time. 4 is above average even amazing screen on time for this phone and stock battery. I suppose there is the possibility of using 0 percent brightness, or even lux brightness or something similar to get the brightness even lower.
You said you use auto brightness, I'm sorry I just don't buy it.
People with the extended batteries are getting 7 hours of screen on time not stock batteries.
7 hours of screen on time is literally double almost every other phone on the market with stock batteries. I really fail to see how having minimum usage and a high performing rom will get you double screen on time.
Edit: with that said, in my current situation I will never have wifi access plus I tether a lot so I really have yet to personally see screen on time since I rooted. Before root and stock I got about 3.5 of screen on time.
Not trying to be a douche or anything just very curious about how 7 hours comes about.

you dont get 7 hours because you are not doing what op did for perfection, and you just like other "4 hour" guys in this thread. I can confirm 7 hours usage is totally possible and what left can support one day idle time when you turn off data etc. Iusually dont do that because I like my phone work at full functionality, but I also like tinkering around to keep maximum use of juice, by eliminating wake locks and autostart.
killing background helps sometimes because some stupid apps keeping using cpu after backgrounded. op go and get a iphone, its perfect for OCD since it can get zero unwanted background activity, amazing idle time and stable usage with relatively easier configuration and tweaking.
1% is NO. 1 battery killer, heat is NO. 2, top up at 100% is NO. 3. Li based battery is at best 40%. but plaese its just a phone, charge and use anytime you want. phone outdated way earlier than battery.

While I understand what you're saying I think you misread my post. I was strickly referring to the screen on time which 7 hours of screen on time with stock battery is inconceivable. 4 is about the most you would normally see.
7 hours of USAGE is common.

Well I mean. You don't have to believe me. I mean I have nothing to offer but my word. I do use auto brightness. But because of the suggestion I'll probably set it to manual and see what that does.
I got 7 hours screen on time with the stock battery. The battery says "3.8 v li-ion battery"
I've gotten more than this is the past but I've also gotten less.
Like I said you don't have to believe me but... I'm using the stock battery.

battery statistics are poor statistics in general. there are too many variables. luckily we have removeable batteries if we need mroe juice.
heres some postings to add to the mix
put my phone through the paces with fantasy football.
held up pretty well. stock battery mind you. on pace for nearly 8 hrs of on screen time. This isnt with typical use though... With typical use I can get 20hrs and 5-6 hrs of screen time. I thought anywhere from 4-6 hours of on screen time was what people were suppposed to be getting.

Yeah we all use our phone differently. I rarely actually talk on the phone with my GS3 because I use my iPhone for that. But everything else I do on my GS3, reading news, some browsing, xda.
I just thought I'd share what I do for people that may want to get better battery life.

Then I shouldn't use the word "usage". I meant 7 hours screen on time. Sometimes I got 8 or more, but only use it continuously after charging, no idle time.

Yet that involves turning off data. IMO the smartphone should always stay online. In my experience, iPhone can get constant -4 ~ -5ma juice flow during idle even with data (2G) and all the push notifications on, which are the only things I want for stay online. I feel its hard to get similar result on my GS3 though.

what you did is pointless. If you leave data on, data is not connected when wifi is connected, and it will connect automatically when no wifi connection.

It's not pointless to me. As I said a few posts before... I have OCD, obsessive compulsive disorder. Things like this affect me. I know that being connected to Wi-Fi that data is not connected, but in my brain, it's as if something is telling me that because my data toggle is on, it's running.
I really can't help it.
