EDIT: thanks everyone for the input! Here's the revised guide:
Ladies and Gentlemen,
The purpose of this how to is to help you, whether new or experienced, to achieve the best battery-life results possible.
This is not:
a magical solution doubling or tripling battery life
a collection of zip files to flash, offering dubious promises
anything of my own making. If I quote anybody and forget to give credit pls pm or comment.
What this is:
Tried and tested methods to *slightly increase* your battery life
An open forum, if I miss anything don't hesitate to comment
I'm organising this post as follows:
Basic: Stuff you probably all know, but here for newbies' sake
Intermediate: More effort involved
Hacks: Root required
[Basic]
1) Turn off wifi, bluetooth, and GPS when not in use. HTC and Google both provide handy widgets to toggle these on and off.
EDITED:
2) Don't use automatic brightness. Use a widget to ramp it up only when needed. Automatic brightness may ramp it too high, and engages an additional sensor so It might actually decrease battery life. ( Thanks droid fetish and magneticzero )
3) Set brightness as low as possible when you can. There's an app called "dimmer" on the market that will set it lower than standard widgets. Use this when you're in the dark.
[Intermediate]
1)Update: The following may or may not help, I am doing some tests to try and get a solid answer: Turn off 4G when not needed, especially if you're in a 3G only area.
to do this dial *#*#4636#*#* then change "CDMA + LTE/EvDo auto" to "CDMA auto (PRL)"
Change it back when needed.
*** I don't remember where I first read how to do this, so if you discovered this please let me know so I can give credit.
You can also get an app from the market by the great folks at TeamAndIRC called "LTE OnOFF" at the moment it's just a shortcut to the *#*#4636#*#* menu, but they're working on improving it.
If you're rooted, you can flash "advanced Radio Tools In Settings" by jcase *thanks for the great tool* that will add this menu into your network settings. (its in rom manager under jcase)
Find the original thread here: http://forum.xda-developers.com/showthread.php?t=1018159
2) Bump Charge. As explained in detail here: http://forum.xda-developers.com/showthread.php?t=871051 (great post byrong!)
follow the instructions here: http://forum.xda-developers.com/showthread.php?t=1016508 (thanks psufan!)
3) Currently there is a bug with certain towers that really drain your battery. Until they get it fixed there's a solution in post 12 of this thread. here: http://forum.xda-developers.com/showpost.php?p=12597290&postcount=12 (thanks Zshazz!)
[Hacks]
1) Remove Bloat.
IF you are rooted, you can use titanium backup to "freeze" (restores on hard reset) or delete apps out of the stock rom. Blockbuster is really bad, as are many of the others.
A good way to do this is to just flash a rom with the bloat removed. They are many, find them in the development section.
I use Das BAMF by adrynalyne here: http://forum.xda-developers.com/showthread.php?t=1009876
2) Undervolted Kernel. Flash a new kernel, a good one comes with Das BAMF, for other roms, you can flash adrynalyne's in MrBobrowitz's section in rom manager.
For an interesting read: here's an excellent post by byrong about the effects of cpu and brightness on battery:
http://forum.xda-developers.com/showthread.php?t=979359
Go ahead and read that, then give him a "thanks" for all the hard work.
Thanks for reading!
This is a working list, so please comment anything that should be added!

Currently running the following tests:
a) run pandora after fresh charge/boot on both 3G only and 3G/4G with screen and volume off. Report ma usage and battery level every half hour.
b) run phone in standby on both 3G only and 3G/4G with screen and volume off. Report ma usage and battery level every half hour.
(calls will be forwarded)
This is no objective, and I see the following 2 flaws:
a) pandora may not have a consistent data usage amount
b) my signal may very for 3G and 4G.
If you can think of a way around this let me know.
Thank you for not putting ATM in here. I would've reported you... fo realz
Hahahahaaa lol! I'd sooner shoot myself. I sell phones for a living, and it took so long to convince my peers about atm its turned me into an anti-atm/atk zealot
Is there still any debate on whether or not turning off 4G has a significant improvement on your battery life? I remember reading a while back (2 weeks ago) that it didn't matter, so I never put any effort into disabling it. But being in a non-4G area I'm sure it doesn't matter.
Just curious what other people have seen/heard.
I will try and do some tests tomorrow... if anyone has evidence pls let us know.
Until then, goodnight
Edit: thinking about it: it might not matter. The rumor probably came from the ego 4G, because wimax behaves like wifi (to my understanding) and is therefore a battery drain. That being said, LTE does not behave that way....
So there are 2 questions in need of answering:
1 does the phone 'search' for LTE in 3G only areas, thus wasting battery
2 does turning it off in a 4G area save battery?
I can tackle the second since im in a 4G area. If anyone wants to test the first, be my guest.
use a brightness wiget and keep screen down until you need it.
Auto brightness is a battery killer...set your screen and forget it
I don't think turning off 4G saves battery, I have tried it both ways at work in a heavily blanketed 4G area, and I can't see any difference. I have also looked at the battery history with phone in idle, and drain seems to stay consistent at about 35-45 mah. So I think it only "searches" for signal maybe if you are in a non 4G area. I never not in 4G, so this I can't answer.

I agree. I would assume it takes more functions to determine automatic brightness then it does to have a set level.
I can't do that, as I am in and out all day. I wish we had some user customizable screen auto brightness settings like luminosity on winmo. That is literally the only thing I miss from winmo. Basically it allows you to set the minimum bightness that you can stand for all different outdoor lighting conditions. Instead of having the standard that goog or HTC sets. (not sure who sets it)
The biggest battery saver might only be able to be done via the user. Maybe if you have Tasker you can set it up, but here it goes:
Some areas/towers cause your radio to drain enormous amounts of power (and it doesn't show up in your Battery Use menu). For the people getting 6h of battery life, I'm looking at you. Download CurrentWidget and find out where these places are. When you discover the areas this happens, make sure your Mobile Data is turned OFF while you're in those areas. You may also use wifi if available. This stops the "bug" from draining your battery.
Normal areas (such as the area around my house) draws 40-80 mA with my screen off according to CurrentWidget. These bugged areas (like certain areas in town, for me) will cause your phone to draw 700mA minimum ... and when I looked through my current widget logs, 900mA has seemed to be the norm. As you can imagine, your battery wouldn't survive very long at all with that kind of drain.
After paying attention to where this bug happens, I've managed to extend my battery life to taking 20% (as in, my battery widget showed 80%) of my battery in 13 hours and 30 minutes. That is a 4x improvement over my old battery life. With careful use like this, you could see 2 days of light-medium usage very easily.
I'm not saying this is normal or that you should be expected to do this... I'm saying HTC/Verizon has a bug they need to fix ASAP, and this is just a stopgap until they fix it.

Wow, so just for giggles I installed that widget to see what I was getting at my desk, and it was running around 380-410mA, turned on the wifi (which also disables mobile data) and I'm down to 150-160mA immediately.
I'm going to enable logging and keep an eye on this now. Thanks for the info!

I can't even take it off WiFi at home even though I am in a 4g area ( according to Vz's map). 4g drops constantly. Sucks.

Ok. Here is where I have a problem. Everybody knows this right? Well, I thought I was having problems with my wifi. It drained my battery down to zero every night no matter what the battery was. With my Dinc I ran wifi (Y5 - so it was automatic as soon as I walked in the door) and the battery life at home was GREAT. Well, not so with my TB. I did notice however that I am on the fringe of 4G/3G as I am on the outskirts of Cincinnati. When I was on data it would bounce back and forth between 4G/3G. So, what I've tried is using the LTE on/off widget I turn it to 3G only when I get home and voila! my battery life is supurb with only about a 5% drop overnight max. This is while I'm on wifi. Why in the world should I have to regulate the data type while I'm on wifi?
Is this possible? Goal is to save some battery on standby, but not by killing 3g completely.
And how much i might save JUST by disabling HSDPA?
Good question. Would also like to hear what others say
Now if it only was a light sabor too....
Try "Super User". I remember seeing an option in it to turn off data when screen off. U cud use one of the options there to turn off 3G and turn on EDGE when screen is off. Being on EDGE saves way more battery compared to standby on 3G.
> Being on EDGE saves way more battery compared to standby on 3G.
Yeah, and for me also 4x higher price for data, and no minutes.
I've had the HOX for about a week now and I love it but I wish battery life was a bit better. I've gotten to about 50% with only a little over an hour of on screen time.
Here's what my settings are:
Auto-sync off, wifi off, gps off, brightness about 15%, and I'm running CleanROM SE. I do live in a LTE however, possibly that's what's killing my battery? I also have a CPU editor running on battery saver mode.
Any help?

Try keeping WiFi on when your in range. It seems to be better than the cell data for battery life.
Sent from my HTC One X using XDA
In my own experience LTE will chew you battery like nothing. Running apps like battery savers etc... actually doesn't save your battery it kills them faster... as they require process to run in the background... just my own tick on the subject.
Switch LTE off and I'm running on 4G I get around 1mb rate up and down for transfer so that's just as good as high speed internet. I'm not going to complain.
Screen brightness is at 35%
Screen timeout 1min
Wifi on
Data on
All others off
I'll average about 19hrs of battery life. Less if I'm going nuts on it like during weekdays at work.
On the weekend I can get 1day 7hours... ishh.

Remove sense
Auto sync on
Wifi on (if within range)
Force 2g network
Auto brightness
LTE/3G only when absoultey necessary
Bluetooth off unless using
Leave GPS enabled
Download timelines free from the play store and periodically look at it to see if apps are continuously using CPU. Some do and need to be closed constantly. Facebook is an example of that.
I would force 2G also unfortunately that's not an option here in town. It's now either 3G, 4G or LTE 2G networks aren't available anymore... sigh.

Thats too bad because calls and texts sent over 3g consume almost twice as much battery. Time to start using google voice!
Your telling. I tried to get 2G on using the GSM only. I can make calls but there's no more data stream on 2G anymore. GSM band once it seems your attempting to make a data connection switches automaticly to WCDMA Preferred.
I wouldn't expect anything less in a Metro area lol... I guess if I was at the cottage I could bounce off the GSM towers to get my service a 2G lol.

Hey well you know what thats not that bad. Use the 2G to make calls and text and just enable the better radios when you need them for data. This would be the best for battery. Just put the toggles all on switches so you have quick access.
Yes, LTE really destroys the battery. If you are using the phone (i.e. the screen is on), and you are using LTE (e-mail/web/etc.), you won't get more than 2-3 hrs of screentime. Without LTE - or in standby mode (i.e. screen not on) - the phone lasts for a long time, unless you are experience battery drain issues, which some of the LTE users are reporting when signal is lost and regained again.

Hes right! Leave every radio enabled cause you never know when you may need to use them. Also turn brightness up to 100% because the screen looks awesome like that. Then all you have to do is have a giant battery hanging off the phone almost constantly. Perfect trade off if you ask me.
LTE is the biggest killer. With LTE on all the time, I get about 3 hours screen on time (which still blows all other phones that I've had out of the water). If I'm on wifi, I can get around 5 with the same type of use.

How do you turn LTE off? I always have 3 or more bars around my area, so bad reception isn't a problem. I just think the big killer is LTE.
Try the CPU Editor, the link is in my sig. It will definetly help on your battery with the right settings eg., battery saver profile. Read the thread and try it out, let me know what you think.

LTE might be the culprit. I get GREAT battery life on CleanROM, but I'm in an only-HSPA+ area.
Some other basic things you might want to try:
1. Confirm that you aren't in a poor reception area. Your standby times will drop dramatically if your reception is poor for an extended period. If you DO have poor reception, consider flashing a new radio.
2. Look for any wakelocks (times your phone is awake while your screen is off). A few every now and then are good, but if there are a lot, or they are lasting for a long time, it'll also kill your standby time.
3. If you notice unusual wakelocks, use something like BetteryBatteryStats to track down what processe(s) in particular are causing them.

Just disabled LTE. Let's see if my battery can improve now. I'm mostly on Wi-Fi when I'm home anyway.
Keep us posted Winters - I have heard some people have issues with this method - that the 3G connectivity drops a lot. I haven't seen this yet, but haven't tested too much...

Hey guys just a quick question. I already get phenomenal idle drain. I don't drop a single percent overnight in an 8 hr period. Couldn't be happier. I also have no wakelock issues However I want to help battery life while not idle.
So I created a tasker profile that enables data when only in apps that need it like Tapatalk. Then when I exit that app (screen still on) or turn the screen off data shuts off.
My question is if I'm going more harm then good with the constant data toggling. I know it's probably subjective to how much I use these data apps so data gets toggled. Is there a way to test this myself?
Not worth your effort. Don't try to micromanage too much.
thats right, enjoy your device instead.
OK thanks guys

How do you get this?
I would just say to one day use your data toggle, and don't the next day if you're curious. I'm usually curious about these things too. I set my Tasker up so it switches to 3G when I'm connected to my work's wifi. My whole work's area has very strong 3G and very weak LTE so I have bad signal because the phone keeps trying to connect to the LTE network. However, my work's wifi is also not very stable and it keeps disconnected which leads my phone to constantly toggle between 3G and LTE. I'm not sure if this affects battery drain but it felt a bit like a drain. I just ended up manually toggling. But I'm usually curious which what drains the battery more. Since your data would be off when the screen is off and if you're not using wifi you should get very good standby time.
Hi
I tried searching Google, but get a lot of different answers.
I live in an area with a very bad cellular coverage. I always have 1 out of 5 bars and when I turn mobile data on, it is mainly LTE, but jumps a bit between LTE and Edge and rarely H and H+.
Can that cause a lot of battery drain? As I just factory reset my phone to get rid of every change I did. I enabled Stamina Mode, surfed the web for 15 minutes and my phone was at 95%. Is that normal? Because if my math is right, that shouldn't give me more than 5 hours of screen time, while I heard people getting 8+ without Stamina Mode.
Am I missing something or is their some very needed settings to be changed? Sync off, GPS off, bluetooth, Brightness is as low as possible, NFC off, black background (less power consumption), Wifi off and Wifi constant searching off.
U can easly check urself how cell signal draining battery ,first Check how it is with normal H+/LTE then charg it again for 100% and use ur smartphone with plane mode acivated ,now subtract result from 2 "experiment"
Also of note is that black backgrounds mean diddly on our displays. We aren't on OLEDs.
Also, if you ARE in wifi area it's better to be connected to wifi. Wifi is closer than the cell tower and data disconnects when wifi is connected.
On AMOLED/OLED black background helps because each pixel is individually lit (Black means those pixels are off). In LCDs there is a backlight providing illumination for the entire LCD so as long as your screen is on it won't make a differrence what colors are on your screen.
I'm having a similar issue. I have very low cell reception at work, and I can get maybe 4-5 hours SoT throughout the day and am at 10% when I get home. I've tried uninstalling/disabling apps that use a lot of battery, so hopefully it helps. I'll update if by the end of today I'm able to get 7+ hours SoT (which it seems it's on track to doing).
Edit: For clarification, the apps I've uninstalled that I believed to be using a lot of processing power/ram/battery were Facebook, [Facebook] Messenger, and Words with Friends.

Just use an app like Greenify to block apps running in the background when not in use so you dont havr to uninstall them.
Brightness can have a lot to play on this one. I tend to go with manual brightness so there's no ambient sensors working all the while the display is on, and if you are doing anything where you can cope with lower brightness then drop it.
Keep an eye in battery stats for "google play services" as this can go nuts. When this happens sometimes clearing data can help.
I also found that using google+ to backup my photos caused a lot of battery drain.
I have not found facebook or whatsapp etc to affect my battery much personally. I use stamina mode when i'm out and about to keep the phone at sleep while the screen is off.

At my house I get just enough LTE to cause our S3 to constantly switch to LTE then loose it and switch back to H+. Battery life couldn't make it thru one day. ATT removes the screen that let's you control network mode but I found a backdoor method to lock the phone out of LTE. The phone now stays on H+ and battery life easily jumped 40%. That's the primary reason I held out this time for an unlocked non-ATT-crippled phone--so I can easily turn LTE off.
Well, tried have my phone on over night (for a change to test it).
Everything off (mobile data, gps etc).
Used 7% of my power and every app was closed. When I looked at battery drain, 55% was from cell standby and 40-45% was from Phone Idle.
Tonight I will try charge it to 100% again and then let it be in Flight Mode to see.
I struggled to flatten the battery on my phone the first day 70% of the day with the screen on, no wifi enabled or stamina.
Another test would be to change mobile settings to 3G or 2G to see what difference that makes. Under settings, wireless & networks, select more, mobile networks, then network mode.
I would try the above first before making your phone completely unavailable, especially the 2G.

What is that? H/H+?
GSM - Edge
WCDMA - H/H+
LTE - 4g
But I think 4g uses less power than edge, but it is more than in my area there is 1/5 in 4g coverage, 3-4/5 in H/H+ and 5/5 (always) if using edge.
As I see an better connection gives better batterylife, but 4g uses way less than 3g/edge if same cell signal.
But is going to try it next time I get down to my dad. He got 5/5 in LTE signal. So gonna see if it can stay at 100% over night.

What is that? H/H+?
GSM - Edge
WCDMA - H/H+
LTE - 4g

Hehe, ok I understand. But HSPA = 3G. [emoji4] I haven't done any rigorous testing, but I think my stand by times are much better using edge (2G) compared to 3G.

I see. But if you change between those, you probs have an better cell signal with 2g (in your area), right?

Nope, coverage is about the same. Generally speaking though, 2G > 3G > 4G when it comes to battery life. That's been the rule for years, but as of late, newer radios have become more efficient with 3G and 4G, thus making the difference less noticeable. YMMV. Would be interesting to see your drainage on 3G as well. ☺

Well could try it tonight.
