I don't know if anyone has tried this yet, but after I have tested it for almost a full work day I can say it's definitely worth using..
Try this: After you completely charge your phone, turn on Power Saver (make sure all options are checked in settings)
Leave it on, don't turn it off, for the entire day.
I had absolutely no slow down.. no problem receiving timely texts/notifications.. the only thing that is a minor annoyance is that screen brightness stays low no matter what, so if you view your screen in full sunlight a lot this will not be for you.. otherwise, HOLY CRAP this makes your phone literally sip power all day.
9 hrs 21 mins 44 secs since I unplugged my phone this morning and I have 63% battery left!
That's roughly 3.96% battery drain per hour!!
This means I will get something like 24-25 hours before I hit zero.. this is with using the phone like normal, where I would normally need to charge after about 16 hours.
Insane. Best battery life I've ever had on a stock phone, and yes I know those monstrosities like the Note 2 can go longer (huge battery..) or if you want to tweak your phone with custom kernels, etc.
But daaaamn I have to say I am impressed.
Leaving Power Saver on from now on!
Btw I should add this is without Wi-Fi, in a LTE area that bounces from LTE to HSPA a lot.. WiFi left on but never connecting to a router

Update. Battery running down a little faster while on my home Wi-Fi watching videos and surfing the net. Don't think I'll make it 24 hours but I am using the phone pretty heavy. I've also noticed that the auto brightness seems to be working overtime whereas it never budged during the day. Tomorrow I'll set my brightness manually to stay at ~30% and turn off the screen option in power saver. See if that yields even better results. So far it appears auto brightness is a power consumer on this phone. We'll see if I'm right tomorrow. I'm at 23% at 14hrs 21mins

I should add that normally I would have charged the phone by now for about two hours since I do most of my heavy usage at night, and when I get home from work I'm already at 20%. But when I've let it run down almost all the way it's been an average of about 15-16 hours
Sent from my HTC One using xda premium
OK so today I kept Power Saver on, but unchecked the "screen" option so that I the screen would adjust as normal to the ambient light conditions. I am finding that the power consumption is essentially the same, very minor change. I now believe that it is Wi-Fi that was causing a quicker drain than LTE/HSPA does, simply because Power Saver does not include an option to cut the Wi-Fi connection when the screen is off.
I will change my Wi-Fi settings to sleep when screen is off and see if that keeps the battery draining at the same slow pace when I am at home connected to my router. I'll try that tonight. If that works successfully, I should get an easy 20 hours + from one charge with normal use (including my evening usage which is heavier usage).
Last night I hit 18 hours and 22 minutes before plugging in at 12% remaining battery without changing the Wi-Fi sleep setting. Hopefully this will be the last test necessary to find the best set up for longer battery life.
Feel free to chime in if anyone else is testing this!
I haven't test the difference between Power Saving and normal. I put Power Saving On in the morning right after a full charge.
I have medium usage for about 20 minutes in the morning using wifi. (It would drop to about 94%). I then turn off wifi and mobile and by 1pm, I have about 82%-88%. I would have about 20 minute usage on mobile data during lunch (flux between 3g, H and rarely LTE). By the time I leave work, it's around 74%. This is when I turn off power saving since I'm usually heading home. Another 20 minutes of medium to heavy usage over H/LTE when on the subway. By the time I get home, it's around 70%. After this, it takes at least about an hour of heavy activity to drain it down to 50% off power saving.
I have the 64 GB Developer Edition and running ARHD 12.1 with the latest T-Mobile Radio.
I've always left power saver on at all times and don't notice any slowdown. One exception is that I don't enable power saver on the screen as it's damn near impossible to see the screen outside. I get pretty damn good battery life on stock rom. Over 3 hrs screen on time in 24 hr period of half mobile data and half wifi.
For enabling and disabling wifi automatically, I use the app wifi matic and it's worked well.

I can easily say the dim screen option is completely unnecessary. Everything is working perfectly, there's no slowdown whatsoever. Even set keep Wi-Fi awake to never. Phone flies, and honestly the data connectivity is ten times better with power saver on. Without it, I would see my phone jump to 2G in a moment of bad coverage and then take FOREVER to reconnect to LTE or HSPA. Now when I unlock my phone it's instantly connected, as if a radio refresh is instant on power saver but laggy as hell without it. I'm very pleased.

Just thinking out loud here...
I don't see how with the data connection off you could have "no problem receiving timely...notifications." What "notifications" are you talking about not missing? Are you saying you actually got cloud-service-based notifications while the phone was sleeping?
Texts/SMS of course would still come in because they don't travel over the data connection, they travel over the voice network.
Email, twitter, etc., they shouldn't get their notifications since that stuff travels over the data connection.
Google Voice users (like me), would miss out on their text messages since those travel over the data connection.
I'll need to test this some. Maybe with the data connection turned off via this setting, the phone actually periodically fires it up to check for notifications, or responds to apps requesting a quick data connection to pull notifications.
UPDATE: Hmmm...turned on power saver, turned on the data disconnect option, put phone to sleep by pressing power button. Waited a minute. Sent myself a google voice # text message and the phone buzzed immediately. Very curious.

I was confused about that same thing. I think it only turns off your data if you havent touched your phone in a while.
If I turn it off, put it down, and pick it up 5 mins later, the data is still connected.
If I turn it off and its in my pocket for an hour, I take it out, the data service is usually trying to reconnect.
I have to admit the way HTC implemented their power saver is impressive. It literally does not delay a single notification. Facebook, Gmail, Hangouts, Scramble with Friends, anything that is set up to notify me works without a hitch. Everything is instant.. compare this to "power saver" mode on the Galaxy line which pretty much cripples the phone.
There is NO reason whatsoever to not have Power Saver turned on with the HTC One. Best implementation ever.
I've had no delays even after not touching the phone for a solid hour. Still get them.

Okay, a little google search reveals the secret behind the data connection magic:
If you want to choose which phone features to conserve power for, tap the Power saver notification first before you turn power saver mode on.
Note: If Data connection is selected, HTC One X automatically disconnects from the mobile network after 15 minutes when it's in sleep mode and the data connection is idle (no download activity, streaming, or data usage). It reconnects and then disconnects periodically when the data connection is idle to save battery power.
This is from the HTC One X support site, but the same quote is on many of the devices, but oddly not our HTC One. I think it's safe to assume it's the same for our device, whether published or not.

My phone's been untouched for an hour or so, and I just sent it a Google Voice text message. Buzzed instantly, and in light of my above research, it looks like you're correct. I'm certainly going to run with this setting on for a day or two at least for further testing. I only have CPU and data enabled in the settings. My testing the next few days may not be the best, as I'll likely be on wi-fi most of the time, although I could turn wi-fi setting to disconnect wi-fi when sleeping.
I've been using that Qualcomm Snapdragon battery guru app, and Greenify on my phone, so it gets damned good battery all things considered anyways, and I also am not afraid to go on charger during the day, but every little bit helps.
Just a few comments on the power saver:
I've noticed that power saver doesn't disconnect the background data immediately... it does it after a longer interval of non-usage.
Otherwise, it's great. I'm not sure if it's the screen dimming or the underclocking, but it really makes a definite difference in the battery life. I also turn it on for a lot of games (cough, dead space) and it helps keep the phone cooler while gaming.

Not the screen dimming, because I don't use that option.

FYI, it underclocks the CPU so the max is about 1.2ghz; When using Faux Control App, I toggled the Power Saver from the notification and can see it go down to about 1.2 ghz when "On" and when switched off my CPU clock maxes out back to 2ghz.

I can also concur to this fact; since day one of owning this phone I've had power saver on permanently set and I've never experienced performance issues like in other phones, its been smooth, and helpful. The amount of usage I submit my phone to in one day its enough to make any other phone live permanently connected to the charger, and I get at least 1.5 days of juice.
I agree, HTC did a good job with their power saver mode.

6 hrs 23 mins 3 secs since i unplugged it and still have 82% without using PowerSafer. switching between very low LTE and very good hspa all the time and i'm using it quiet often checking facebook, twitter, mails, whatsapp and news.
The only Powersaving App I installed is "Wifi-Matic" wich turns on Wifi only if i'm connected to a specific radio station. Check in to your wlan one time and it will safe the radio stations around. if you aren't connect to this stations it will disable Wifi by itself. Works great for me! (Checking radiostations every 15 mins).
This means for me loosing 2,889% every hour without dimming the screen or something else
Give it a try and compare

How about you try that, with power saver on as well, and report back?
Besides, if you're barely using your phone at all, then yes it will be saving power with sleep mode alone. All I know is I have several friends who move in and out of bad reception/data areas, and now their battery is lasting a whole heck of a lot longer using power saver. It sounds like what you're using is somewhat of a power saver as well.. but you are in a good coverage area too so it's hard to say.
Btw, my figures were with Wifi always on - never switched off, ever.. and I still had greatly extended battery life.

Wanted to know from those getting 2 days out of the mini pro, what are your systems settings to make this possible.
1: I have my screen to less than 50%, can only still manage a day.
2: Do you guys turn off 3G HDSPA?
3: Does wifi use more or less battery than HDSPA?
4: Any of you using a blue tooth headset?
5: Any specific apps to kill?
6: Any special battery conditioning done? If so steps?
7: Do you guys have exchange e-mail on? push or pull?
The battery meter is showing more than 50% going to the screen.
Good that it seems I don't have an rouge apps and the wireless doesn't seem to take up too much battery, but a let down that I can't get more than a days worth of battery.

Why are you trying to make your battery last 2 days? Do you not have access to a charger everynight?
Also I do not recommend you 'kill' any apps, due to the nature of Android. If you 'kill' an app, it's very likely it will just start up again, using more CPU cycles than if you just left it idle. This is especially an issue if you are using an auto-killer.

1. set 40%, add widget at front wall for fast switching (to 80%)
2. turn off mobile network (data), add widget at front wall for fast switching (to enable)
3. -
4. no
5. using system panel lite to clean and root uninstaller to remove apk at system app (currently memory at 230M-240M)
6. restart phone 3 time per day, use 1800mAh, charge phone when >5% energy, to 100% (45minutes), turn off while charging is more better.
7. no - exchange e-mail running at background processor (any unwanted background I will kill or remove; currently only 3 apps still running)
use dark theme/wallpaper for energy efficient (low brightness) and use earphone to listen music

I'm not sure what value this message is supposed to provide. I've seen folks post that they can get 2 days or better out of the phone, if so what's wrong with wanting to do the same?
Also note that there are times when it's inconvenient to charge and I'd like to defer charging. I'm pretty much out of juice by end of day the work day, but would like to have a few more hours of battery left, having the phone on the charger all the time isn't always convenient.

I understand if your phone is starting to go flat then you might want to start conserving battery, but if you have the ability to charge it then why not?
I agree with r33p. Using a task killer is possibly one of the worst things you can do to try and save battery. Using less memory does not save battery at all.
Also im not sure if this is true, but using a dark theme does not save battery as the backlight is still on, but screen is just 'hiding' it to create the black you see. So if anything it uses more battery.
I tend to keep a widget on my home screen to turn off data, wifi, and bluetooth. I turn them on when I need them, turn the off the rest of the time. As long as you aren't doing heavy internet browsing on your phone, you should be able to get two days use out of it.
Hopefully we'll get some custom roms for these things so I can justify rooting my phone. Then I'll uninstall all of the stock apps I don't want, both to clean up my app screen and to hopefully stop some of those background processes I don't need.

I must agree. Using a dark background does not save battery. That only works for oled or amoled based screen like the galaxy s series. Also they're right, don't use a task killer. Terminating apps just consumes more battery.

3. i dont know but i turn off wifi en bluetooth whenever i dont need it.
4. i use bluetooth in my car tot connect my phone with my car. unfortunately this uses a lot of battery by being just connected.
5. i kill the popgames, this uses a lot of battery
6. most times i let the battery go empty and only then start charging with the powerconnector, not through usb with a computer.
7. i dont have exchange but imap push email and another account pop3 which connects once every hour. i use the app k9mail
last weekend i did 2,5 day but i was abroad and didnt have roaming data and turned off wifi en bluetooth.
i did 1% a hour except when i was driving and connected my phone to my car.

Does 2g only save battery over wifi and 3g? If so, is it sufficient for e-mail?
Mike
I normally put all of my most used widgets on the front page for quick access
3g or wifi pref. 2g is painfully slow.
Yea and forget appkillers,delete the apks or freeze the unwanted services.
The tricky part - what (not) to delete.

yes 2g saves battery
i was told that because of the continues switchting between G, 3G and H the battery consumes a lot of energy.
when you put it on 3g only or 2g only it saves battery.
becasue i dont have 3g everywhere i go i put it on 2g so that i can make calls everywhere i am.
if i need to do some things on the internet i switch it back to 3g.
2g is enough to recieve mail and whatsapp messages.
my mail wont come in as fast as wifi or 3g but that doesnt matter to me.

How do you set it to H only? Is this via WCDMA only?
I'd love to drop the bloatware, but want a clean root option that won't affect functionality.
Mike
I have about 2 days. Currently I'm on 82% 12h since charge. My experience:
1. I keep 3G switched off most of the time when I'm outside. Only if I really need the speed for uploading a photo or update an app.
2. I keep Wifi running all the time at home.
3. I have disabled Location&Security both Use network and GPS. These seems to drain battery even if maps and latitude is disabled.
4. In the carrier settings I have disabled automatic mode and going for manual mode and selected my carrier.
5. I always use the back button on any app until I reach the home screen before locking.
My idle drain is about 1.5-2%/h when I'm at home with wifi. Outside with 2G it's draining a bit more and with 3G it uses insanely much battery.
I have lot of push services running (fb/g+/twitter-notifications, Whatsapp and gmail + an Exchange account)
I have also noticed that the battery calibration is a bit flaky. From time to time I run the phone until it dies (sometimes at 8-10% but sometimes at 30%). Then I'm unplugging the battery for a minute, plug it back and charge and it have calibrated and doesn't die at 30%.
Another thing I have noticed is that I can't get more than 4172mV charge. The battery should be able to charge to 4200mV.
Two good apps for monitoring battery usage is BetterBatteryStats and Battery Monitor Widget (which is more than just a widget)
do you guys charge till it reaches 100% or just till it turns green?

thats one other discovery I have made.
when the phone says 100% it's actually still charging (can be seen that there is a charge indicator at the battery and also can be seen from Battery Monitor Widget)
Another thing is that when it has reached 100% it starts to drain battery until it reaches 95% then it starts to charge again. (nothing uncommon with that) but the phone still shows 100% so sometimes when it's unplugged it can actually be at 95% (but starts to countdown from 100%).
Battery Monitor Widget can alert when it's actually fully charged with a notification.

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

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

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

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

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

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

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

Does it matter if I turn off data or it will still drain looking for cell signal?
As long as you don't have partial wake issues, there are only two real concerns for battery.
It's not processor. Again, if the phone's not 'awake' while the screen is off, your phone's processor is not ramping up to full speed at all. While it's on and in your hand, 1.5ghz is a great speed for it to operate. Slower speeds than that significantly slow down how your phone operates, and you will have your screen on for seconds longer (Which uses WAY more battery than the higher clock speed).
In Facebook app, go to menu > settings > and change the refresh interval to NEVER!!!
As of Android 2.2, Facebook does push notifications. You don't need Facebook refreshing very 4 hours (OR EVER!). This wakes up your phone (ramps up processor speed, and so on), uses data (battery), and is unnecessary (since you get push notifications anyway). Turn that crap off. Same with Twitter. Turn it down to manual refreshing only (look in settings > accounts and sync as well as in the app). Same with Friendstream (which will automatically have its own refresh settings - fix them).
There are two things that use your battery.
1 - Screen. Turn your screen off when you're not using it. Stop turning your screen on every 12 minutes to 'see if you have any notifications'. Trust the green LED blinking light, or listen for your phone. You can stop checking it. You're using a TON of battery lighting up that 4.3" screen AND waking the phone back up (ramping up the processor, among other things, and it will stay awake for at least minutes, even after the screen goes back off).
2 - Data. Turn wifi off if you're not using it. Turn Mobile Network (GASP!) off when you're not using it. Pull down your notifications and hit Quick Settings, and turn Mobile Network off. Don't have that? Make the HTC Widget > settings > Mobile network. Turn it off when you're out with your friends after midnight. a) you're not going to post anything reasonable or coherent when you're out drinking anyway to Facebook, and b) call and text still works, so you can still mack on honeys all night (and text them drunkenly). You don't need your damn Gmail at 1am. I know you don't. Don't try to convince me otherwise.
If you keep your screen time to a minimum (and brightness down if you're not using auto brightness), and TURN OFF mobile network (internet) when not using it, your battery will last DAYS. Yes, the stock battery. Now, do you do 100+ texts per day? Sorry, your battery is going to die today. And tomorrow. Every day. The screen time murders the battery, and the Wake time that your phone will have as a result (like every time the phone lights up - for minutes at a time, it'll stay 'awake').
That's how you keep your battery going. On any android phone. Yes, an extended battery works great. I bought one (half price in a verizon store) AND got an EXTRA one for $4 (on amazon.com). Yes, it's for thunderbolt, but YES it's the same part number. It's running my phone right now. Keep it charged, and in your glove compartment. Your life will be better.
http://www.amazon.com/dp/B0055OTNK4/ref=pe_175190_21431760_C1_cs_sce_3p_dp_1
Go get it. Turn off your internet, and your screen. Trust your LED notification light. Stop using MMS Screen On. Your battery will last all day, every day. Unless you text a lot. Then, good luck.

In short, yes.
If u turn off data it will help. But you will still have poor signal, so Idk how much it will help. apps and processes that use background data won't be using it, that alone will keep your phone from reconnecting so much, so it will help.
It takes your phone longer to connect on poor signals and your speeds are slower so it takes longer to do the same things. This also keeps your processor running faster for longer times.
One thing I found to save power that I don't really see posted anywhere is by using this app: https://play.google.com/store/apps/details?id=AutomateItPro.mainPackage&feature=more_from_developer#?t=W251bGwsMSwyLDEwMiwiQXV0b21hdGVJdFByby5tYWluUGFja2FnZSJd
I have it programed to turn off 3G/mobile data when it screen's off....unless I have a certain app running like say the browser. It will then keep data connected until the browser is closed, then the screen turned off. I then have it turn 3G/mobile data on as soon as I screen on again, so it's ready to rock instantly. I personally noticed a huge difference in my battery drain when not using the phone.
The app is pretty cool, you can program a ton of things. I have gps auto turn on when I use G-Maps or GasBuddy, then it auto turns off when I close those apps. Saves time and juice imo. Just figured I'd throw this out there.
nice app. isn't there a setting within the OS to do this, though? pretty sure there is.
either way, agreed. data usage can/will cause battery drain.
the real perp is your display, however. adjust your brightness settings, you will see significant battery improvements.
My display is set low, and all my other settings are set to be battery friendly. It's been awhile since I used the app. But after I had that setup, I noticed better life instantly. Went fishing today with the little guy, left the house with 100%. No phone usage for 2hrs, and it was still at 99%.
Can't you do this without the app tho

If there's a way to set the phone to turn the radio off when screen is off, I'm unaware of that. I tried turning it on and off manually, but it got to be a pain turning it on and off all the time. I would end up just leaving it on. Now I don't even have to think about it, and it gets done everytime.
Sounds similar to Tasker, which is a little confusing to new users.
But as for your post, turning 3g off saves a TON of battery. I have to keep it on during the day to get emails for my job, but at night, I turn 3g off, and the phone will drop maybe 2% overnight with 3g off.
The CDMA version of the 3D has a setting in network that allows you to turn off your mobile network if the screen is off for 5+ minutes. The setting is "turn off always on mobile network". But the screens needs to be off 5 minutes before it will. This setting will not turn off wifi though.

If you wanted to save battery life without downloading anything you could just use the HTC widgets for mobile network, 4g, WiFi, and GPS. This method allows me to switch the settings on and off on the fly. I've also found that if you disable all GPS options it won't be running in the background and for apps that require it. And if I'm in one spot for a while I just use WiFi.
what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.
I'm experimenting a bit to see if the Omate TS would be a usable replacement for a phone (ie if it would work well during the day to read notifications, use for sports tracking, recieve calls and such).
It started out well - when I took the watch off charging in the morning I activated the phone, WiFi, bluetooth and paired my bt headset, and turned off cell data. I played around with the phone a bit (installed an app, played with that for a few minutes, checked settings and tried some new things there for maybe 10 minutes or so, and so on). I recieved two calls that lasted about 5 minutes each, and checked mails, facebook and such a few times. After lunch the battery showed 78% remaining, which sounded very good.
I decided to take a walk, so I turned off WiFi, enabled cellular data, and turned on GPS. Listened to podcasts through BT headset for the entire walk. One hour walk with RunKeeper, where I checked mail and facebook a few times during the walk.
After returning, the battery was down a lot, to about 25%, ie 50% battery drained in one hour. I checked the battery stats, and it looked like this: (not a link as I can't post links yet due to forum restrictions): imgur.com/WPQJNd4
I'm not surprised about WiFi and BT consumption as I had those enabled and used them quite a lot during the day, but what surprised me is the cell standby adding up to almost 50% of the battery usage, most of which seemed to be drained when I enabled cell data. Is GPS drain included in cell standby as well? Is this to be expected, or what's causing the excessive drain when using cell data connection? Any tips on how to improve this?
My cell coverage during the walk was decent, as I was outdoors and had at least 3-4 bars of reception the entire time.
cell standby is also the highest drain on mine. was on 2g only as well

I get about 2 days of battery with emails only, light apps use. 3g and wifi on, no bluetooth connected, zero calls.
8 calls, some messages, BT always on with headset, on 2G GSM, light app usage with brightness on min and i ended on 4th day still with 40%battery left.

That's quite impressive!
I tried again today, took watch of charger when leaving for work. 1 call, 10-15 minutes of "play" (installed an app, changed some settings, re-arranged some icons and such). BT with headset, WiFi and phone enabled all day, mobile data connection off. Recieved quite a few notifications during the day that I checked briefly, but other than that quite idle. When leaving the office at the end of the day I had 52% battery remaining.
Not too bad, but out of that the cell standby and phone idle together consumed half of my battery. Reception is ok, ranging from 2 bars to full (goes a bit up and down). I can't complain about the wifi / bt / screen battery drain, seems the phone standby is the only major battery hog for me.
Cell Standby is a battery hog for me too : about 10% an hour. Cell signal is good. Will try now to disable the mobile data to see if it helps.

That's amazing, what is your setup (hw revision, firmware, settings, etc)?
Disabling cell, wifi, bt, gps, lowest brightness on modified stock (the 2014 testing as a base, ensec, xposed) and I can just make it barely back home on 2nd day with light usage (check the time mostly).
In comparison, my Pebble gets to 30-40% on the 4th day and will die out completely by the 6th day.
Even though the cell standby seems to drain a ton of battery, overall it's acceptable. For normal usage (WiFi on, BT on, paired with headset, phone on, a few widgets and apps that are pulling info from the web, receiving a couple of notifications per hour, checking time/notifications a few times, making a few calls and such) I seem to average about 6-8% per hour. Half of that is for the cell standby, so turning the phone off would probably double my battery life.
I know there are a number of "battery saving apps" out there that modify settings and behavior to save power. Mostly stuff like turn wifi off when screen is off, enabling it once every few minutes to check notifications, and similar. Anyone know if these apps can tune the phone power consumption in any way?

I started running Deep Sleep Battery Saver as I had prior experience with it working well on an SII as a set it and forget application, where other similar programs require much more customisation. keep in mind my omate is not a daily driver, it spends half the week on the charger and the other half on my wrist, and I only use a sim card in their sparingly. as such, I don't have proper data, but I've definitely been able to make it through the day with light usage, occasionally forgetting to recharge until the next day
I think there may be something wrong with either the battery or the circuitry which monitors and reports on the status. I can watch an hour long video with negligable 4% battery loss one day, and another day a similar video draining over 20%.
Certainly with all the radios switched off and very light usage my TS was on 92% well into it's 2nd day...
However soon as you use it... it gets murdered.... lol....
From wednesday till now, few calls, bluetooth on, some texts, very light usage.
