[Q] juice defender

Aight so I downloaded juice defender free last night cause I've been having battery heat problems.....but it shuts off my 3g connection when the screen goes off and I can't seem to find the setting for it....I use Pandora radio so this is a bit of a *****.....any solutions?

Thats pretty much the only thing Juice Defender free does that can save your battery, that and turning off wifi too. So if you disable it why even have Juice Defender installed? I too tried the free version for about 2 days and could never get my wifi or 3g to come back on so I uninstalled it and thanked god I hadn't paid $10 for the paid version. IMO its crap.

Juice defender is terrible. It kills your battery. well thats my experience...

Terrible app. If it does anything then it kills the battery... Brings android system to the top of the usage list, because it shuts off 3g and wifi..

Screen is still the top on my usage.
I have the paid version. It gives you the ability to lock items (like Pandora) "on" for data usage. Then, they don't get killed.
I had amazing battery life with it on my D1. Jury is still out on the Incredible. I'm still working through ROMs and Kernels.

I use it also. It has this new feature that you can tell it your local wireless and leave it alone. Problem is it doesn't work. Keeps shutting off my wireless when I'm using it! Very frustrating.
Also their developer is not very accessible. They want all issues solved through their forums. I hate that...The best software also has an accessible support system.
The one good thing I will say about it is it has the potential for taking over all aspects of managing your phone. A one stop shop. Just not there yet...

I used to use Juice Defender with 2.1 and found that it helped battery life. However, with Froyo, it just made the phone unstable. (It'd just sponaneously reboot sitting on my hip 2-3 times a day.) After uninstalling all is well.
A co-orker's Sprint phone had the same flakyness until he uninstalled JD.

Wild! I have never had random reboots. But, we all know how unique these devices are... even between the same model.
With warm twopointtwo, it doesn't seem to be turning on all the time... or warm is somehow killing it.
dbaps - are you still in 'training' for the wifi? It takes JD a couple of times to fully learn your location (based off of towers) and remember that as a wifi location. Check under the settings...it'll tell you what percentage of training it has completed.

Those of you who say its crap obviously dont have it configured correctly. I bought "ultimate juice" and when you go into the custom or aggressive profiles you can tweak everything until your heart's content! It still seems to shut off data when Im streaming stuff with slacker and connected to wifi, even though I tell it not to. Other than that it definitely will give you a few extra hours if you spend the time to configure it properly.

Terrible app!

There is no correct configuration to this app. That is why it is called "Custom". The reason it is CRAP is due to the reason you list as a problem among numerous other features that don't work.
Seriously, why have an option to automatically tweak CPU values if the option doesn't work with 99% of the kernels on the market, which also includes the STOCK kernel?
Yeah, it's a GREAT app!

True. For clarity's sake, I was using JD free so I don't know if any other version would have been better or worse. It's possible that the complex WiFi network at work (multiple APs per floor with a centralized controller) confused things.
My phone is a droid incredible, the co-worker's is a Sprint Epic. Different symptoms - he had phone lockups requiring battery removal to recover. Rooted, re-ROMed and still crashing until Juice Defender removed.

If you use Ultimate Juice and set up things correctly. This programs rocks.
It will turn on and off your data (3g and wifi) when you need it (according to the conditions you set).
It takes a little bit of reading and intuition, trial and error, and PATIENCE.
Use it for more than 1 day. Your phone usage varies day to day.
Again, read the text, THINK, and setup the conditions according to the way YOU need them.
I get at least 20-40% more battery depending on how I use my phone. I rarely charge mid-day any more and I can count on my phone having battery throughout the most useful hours of the day.
On light to moderate use, I get at least 14-18 hours. Just for fun, I once tested it and got about 29 hours before the battery hit 5%. That's with a little texting and a few phone calls. I use the stock, standard capacity battery as well.
SET IT UP RIGHT!

I've had no issues with JD running on 2.2.
Set on Aggressive. Only annoying thing is that I get the error notification icon for Weatherbug Elite every two hours because data is shut off.

First - I've got the most recent JD installed. The old one was kind of lame. People have made some good points, but there is a lot of incorrect information in this thread...
It works. If you are *NOT* actively using your phone, it will save your battery by disabling communication you don't need. I can go to bed at 80%, wake up 7 hours later at 79%, maybe 78% at the worst case.
If you are using your phone, it's quite nice - it comes on quickly - and manages my network well (at home, uses WiFi, elsewhere - 3G).
It's not $10.
My wife is using the free version and has had zero problems.
I've never tried aggressive, but maybe I will.
I cant comment on the CPU stuff - never used that.

I've never had a problem either. I'm running Skyraider 3.5 with incredikernal 2.6.32.27. I have the free version set on advanced. The best battery lift I've gotten with light phone use, texting, data syncing and browsing was 72 hours. Same use with stock rom and kernal my best was about 18 hours before I needed to charge. I know everyone is different, but that's my experience.

When I tried it back last Fall the paid version was indeed $10, its now down to $5. Which I still believe is way too much for this app. My 3g would not turn back on no mater what I did and yes I read the tutorials many times and had it set properly.

Perhaps for you. For me (stock ROM on my dinc) it made the phone unusable. Calling that observation "crap" or "lame" is convenient, but doesn't reflect the experience that I had (and which others had).
Again, with Android 2.1 JD did help a great deal. With 2.2, it didn't help battery life but made the phone crash. This was not a positive trade-off.
With froyo, I can go two days on my incredible between charges given light usage without it. Why put up with the instability just to get a few extra hours of battery life?
For example, I'm currently at 62% after 15 hours since unplugged with moderate usage of the phone, with WiFi and Bluetooth enabled. I could just turn off Bluetooth except when I'm in the car, but I doubt it'd buy me more than a few extra hours of useful life.

Juice defender has caused me multiple problems. Was the source of phantom call drops and sleep of death!! As soon ad I removed it, problems solved.

Also corrupted two SD cards, losing all my files, because of sleeps and reboot caused by JD. Does not play well with Z and HD roms at all. Works at first but soon became the cause of a lot of problems.

2g/3g/4G Juice defender beta

Anyone use this from the market?
I wanna test out the 2g/3g/4G mode but it's giving me a warning that it could break my data and not able to be restored so I'm too chicken **** to test it.
Sent from my Galaxy Nexus using XDA App

Yes. Swear by it.
There are plenty of nay-sayers, and no doubt you'll hear from them here. I wouldn't argue the experience they've had, but then, I don't see why they argue mine (and other happy users).
I had terrible problems with battery drain on my Epic 4G. I had a lot of crap running, keeping the radios alive all the time with little junk that was just fine updating in bursts every 15 min. when JD wakes up the cell radio for apps to do some traffic.I'm also not OCD enough to remember to turn my wifi on and off.
Anyway, with JD and my configuration, I sip electrons. Take JD away and... not so much.
Put it on the GN and it seems to be working just as well if not better. I see threads full of people complaining about battery life -- I'm easily getting a day and a half out of mine with moderate use (maybe 20-30 min total talk time, some internet, YouTube, 20 minutes of gaming, and other typical usage). Sitting on standby, I lose about 1% and hour.
When configured properly, I find JD helps a lot, chiefly by automatically managing the radios. Worth it.

But do you specifically use the 2g/3g/4G toggle or do you just have your profile set to turn data off?

Yeah, sorry I wasn't more helpful about that. I only answered your first question
I don't use the specific toggles. I just turn data entirely on and off. I didn't see the benefit of switching specific data modes.
Yes, 3G uses less power than 4G, and 2G less than 3G, but OFF uses the least!

Haha np, I just like to be able to get my emails and mms etc.. At all times.. But hate leaving 4G on..
Just thought it would be perfect to have a profile to turn it to 3g or 2g like 30 seconds after the screen goes off..

Juice Defender is, without a doubt, the worst app I've ever paid for.

I had problems with JD on my SGS but it seems to be working much better on the GN. Stops the battery from draining while I'm not using the device. The main thing I'm using it for is controlling WiFi by location. I only have a few apps enabled with the screen off so it shouldn't be using a lot of data.

JD worked great on my SGS2 and works same way on GN - thanks to JD I loose just 2-3% over night.
I don't know if it's bad configuration or ROM incompatibility for the people that complain about JD.
Anyway, I have seen that 2G/3G/4G option but didn't have time to look around after beta version, anybody care to share a link? I would like to see if 2G is good enough to keep my internet radio going, it's currently killing my battery, like 10-20% per hour. Is there an option to use 3G, but no HSDPA?
When idling, with properly setup JD schedules and triggers and auto-brightness also managed by JD, I get great battery life.

I may as well weigh in with my view on this, as an agreement with both sides. When I had JD Ultimate loaded on both stock and custom ROMs on my Gnex, I undoubtedly saw battery life gains when the phone was idling, and they were significant. However, far too often I would go to unlock the phone, and the touch screen would be unresponsive and I would have to battery pull. Not once has this happened without JD running. A couple of times a day with. So it worked for me, but the instability that came with it was too much to bear, so I uninstalled.

Yea I know it's possible, but I just like that JD manages so many things for me, like auto-brightness, radio schedule or that it automatically enables WiFi when I get home and disables it when I leave and can do the same with Bluetooth if I wanted.
Surely I will uninstall JD when I loose interest in its advantages or when I find a different app that works better for me or when I simply get bored with it.
I only had to pull battery once since I installed it, which is not that bad. If it starts to annoy me, I will get rid of it. But so far it's ok.

My issue is that I don't want something controlling my phone. Too much control. I can all those things myself if need be. Isn't that the whole purpose of Android phones? To have control?

Sounds like the solution for you is simply not use JD.
For me, the solution is to use JD to let it manage some boring things for me so I can focus on other more interesting stuff.

This.
Except never had a crash or lockup, never had to pull battery.
I'm a flash maniac, hacker, and mod extensively. I run a lot of crap on my phone. JD does a great job managing things automatically so I get great battery life.
That is, JD ultimate... the free version is way too limited.
Only problem I've ever had is JD bring really slow to turn data on when I wake up the phone, after its been running fora long time (like into the second day). Fixed by stopping and restarting JD most of the time.
Rarely happens because I reboot at least once a day for one reason or another.
Arguing over whether JD is "great" or "crap" is so juvenile. The fact is it world great for some, not for others. This speaks to configuration differences, not JD. Is Supercurio's voodoo sound crap because it doesn't work on some configurations? Of course not.

To offer a different perspective, I don't consider something for which I control the parameters to be "not under my control". I'm not seeing how JD's behavior is any different than the phone automatically connecting to a wifi AP if you leave you're wifi on without you explicitly telling it to connect.
If JD simply enabled some vague power savings through turning the radios on and off, without knowing exactly what triggers the control, I'd stay far away from it too.
Sure, its turning radios on and off, etc. -- exactly as I've instructed it to. I'm in complete control.

ics and battery life

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.

Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.

biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.

I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

Battery Drain

Is there an app or way that conserves the battery power. The phone is still completely stock but it received a firmware update through Tmobile and ever since then the battery gets drained by 4 pm (after all apps are x-ed out and phone is just in standby) the batter drops to around 30 percent... what can I do? I don't think it needs a new battery since its only a few months old... suggestions?

I dont know how much you use your phone and weather or not you watch movies or download files with Wi-Fi alot but it could seriously drain your battery if you leave things like Wi-Fi, Bluetooth, NFC, Brightness Up, or use live wallpapers.
If not, I would recommend checking your battery against someone elses because I've had a phone before that had a bad battery that could explode and caused me to have battery issues. Make sure your battery isnt swollen at all and if it is make sure you take it out and dont put it back in and go to a Battery+ store nearby and I'm sure they got one for your phone (they come with warranty).

Well my wife and I have the same phone and it does it to both. I don't have signal in my job since they have a Verizon antenna and it blocks our t mobile signal so I don't use it during the day which means the phone is just on stand by for the first eight hours. I make sure I turn off wifi, blue tooth, GPS etc and close all apps....but by the time I get out of work it's at 30-40% power.... both phones were bought this April so was hoping it wasn't/isn't a hardware issue and have to replace the batteries....

This is where the world of rooting and tweaking your android becomes extremely attractive.
There are ROMs that last 1 day + ( that's 24h+ hours of battery)
Only need two things....
1. Patience - to sit, read and closely follow instructions
2. Guts - to take a dive and risk ruining your phone. (Which doesn't happen if you have number 1)

2. Build.prop tweaks
3. UV with a custom kernel
4. Lowest screen brightness (doesn't require root)
5. Restrict yourself to 2G networks either using AOKP settings or a build.prop tweak
There are others but this is how I achieve great battery times mostly.

Why not try and find out what is using your battery up first? Try GSAM from the play store, its free for one, easy to use, it will show you what is draining your battery, there are a few paid ones as well, but try the free first , HERE is the direct link to GSAM.
or QR code, just scan it with phone.

Well my wife and I have the same phone and it does it to both. I don't have signal in my job since they have a Verizon antenna and it blocks our t mobile signal so I don't use it during the day which means the phone is just on stand by for the first eight hours. I make sure I turn off wifi, blue tooth, GPS etc and close all apps....but by the time I get out of work it's at 30-40% power.... both phones were bought this April so was hoping it wasn't/isn't a hardware issue and have to replace the batteries....

That is a very weird situation and try a app that shows the apps using battery. Even check the stock android battery section in settings and see whats getting used. Your brightness should be first since it can really eat your battery if its turned up. I dont think its defective since both your phones are having the same problem but both my parents have the 4.0.4 firmware installed on their T989's without a problem and get decent battery power. I however am using a custom rom with kernel. Did you use the same battery for each phone? or each phone has the same problem with their own devices and their own batteries when getting updated to 4.0.4? If you used your battery on her's I'm assuming the problem may be the battery and you just got unlucky with a defective one.
P.S. I'm assuming 4.0.4 because thats the latest update to ICS for the T989 on T-Mobile.

The battery manager that comes with the phone identifies the display, but I've set it to lowest setting and have a dark background. And yeah both phones have their respective batteries which makes me think it's a software issue.. We just upgraded to the 2.3.6 ( I guess t-mobile is a but behind lol). But I going to try the juice defender tomorrow... It's just while I root the phone and get a custom ROM... (doing my homework before doing anything since it'll be first time)

Those apps wont really help, it basically does what you can do manually, turning off settings or putting them at low usage. Rooting is the way to go, its rather simple, once you do it, you will have wished you done it sooner. Trust me, I was in the same boat, I had just got my phone last december, the wife and I were in Vegas and my battery was horrible, I was taking lots of pictures and video, but my battery was dying. I had no way to charge it til we got back to the hotel, next day was same thing, horrible battery, this was all before ICS even was around for this device. When I got back home, I rooted my phone, to date, I have gotten a best 44 hours out of the phone. I ROM hop so I try out the variety, there is how to's and videos here and youtube, you will kick youself on how easy it truly is to root and flash. GSAM will show you in more detail what is using your battery the most, good luck with whatever you choose to do. There are many people here who can help you along the way, thats what this site is for.

Juice Defender will help a ton with you're screen being off for extended periods of time. Normally without it, I lose 30% at work without touching it. Today, I have lost 6%. The margin won't always be like that but it's a sizeable difference. Also, I have an app monitor application you can use to track rogue apps. There is also this app called Autostarts where you can disable an app from opening and it's really useful for apps that you don't need running in the background. Turning off auto sync will help as well IF you are okay with not getting every email in 5 minutes.

[Q] What is the typical battery life on a stock/unrooted One?

First off, I would like to say that I have searched several times for this answer to no avail.
I just came from a Maxx HD (XT926) which obviously had phenomenal battery life. So I'm not terribly surprised by the reduced battery life moving to the One. However, I'm currently only getting about 8 hours off of the charger with 2.5 hours screen time. Via GSam, there do not appear to be any terrible wake locks or rampant apps running in the background. I typically observe a wake time of +/- 10 minutes from my screen on time.
My typical usage right now is some heavy texting, light Facebook browsing, a GroupMe thread, and that's about it.
System settings are generally screen brightness on one bar (from the notification pull down, not sure what the actual percentage is), wifi/bluetooth/gps OFF, NFC and mobile data on all the time.
I have disabled the location via wifi options, so that's not currently a factor either.
What is the typical off charger and screen time for you folks? I love the phone, but a bit frustrated with the ~10% per hour battery drain at idle...
Thanks in advance for any input!

unrooted this seems to be the norm. there's a slew of VZW bloat apps that will check to see if you are using them once an a while, also blink feed refreshing often will have this impact.
right now on rooted Ecliptic rom i can get about 12 hours up time with 3.5 hours screen and still have 45% battery left. This is mainly on 4g some WiFi. this a 4.4 rom and has the options to turn things off the stock system cant like blinkfeed.
-wait till the offical comes out ( rummored to be at the end of this month) it should help-

Thanks, Synisterwolf.
That definitely helps put to bed some of the concerns I was having.
I'm definitely not opposed to rooting, but if I remember correctly, build 2.10.605.1 doesn't yet have an exploit, correct?
Again, thanks for the input.

That seems low to me, even for stock. Granted I debloated even when I was running stock, since I was rooted. I was getting closer to 3.75 hours of screen time for that amount of time off charger. But like I said, I was debloated.
Edit: I also don't use NFC, so that was off too. Not sure how much NFC affects the battery, as I've never really used it on any phone I've had.

there are a lot of things that can make the battery not last. i know the bloat the try to see ya is one of them
@ op no exploit as of yet. but on 4.4 you can go settngs > apps > all apps and click the ones you want to disable. its almost like uninstalling them for the non rooted devices.

I think there's a disable option option in 4.3 as well, so I'll give that a try.

Completely stock, bloatware disabled. 2.5 hours screen on 14 hours heavy use.

Ouch... I'm way off then.
Has anyone compiled a list of safely disabled bloatware for these? Or is it kind of trial and error?

Stock won't let you disable anything that can cause issues, as far as I know.

Awesome. Now hopefully there's less chance for me to bork my phone.

With the help of Green Power Premium, my phone lasts 14 hours with moderate use and 8 hours with constant/heavy use. I don't use NFC or Bluetooth and turn off gps when I'm not using Google Maps. Honestly this phone is a god send coming from an Incredible 4G LTE

You can range between 8 and 16 unrooted stock. Depends on the use age and what you use. I do know with viper ROM and elemental x kernel its has superior deep sleep and hardly uses the battery at all. To give you an example of stock and other ROMs/ kernels I use to get about 14 while at work and finish with about 14% battery life at the end of my 12 hr shift. With my current setup I can go the 14 hr run and have between 75 to 65 percent battery life left and this is with sync active for mail Facebook and so on. So that's just an example of stock vs rooted.

With moderate use I drain about 40-50% of the battery throughout a 15 hour day. I'm running a battery saving script though which disables 2 minutes after screen off for cellular and 7 for wifi with interval updates. I also disabled a bunch of permissions for apps that I know I'll never need but for apps I frequent. On average I use my GPS for about 20-30 minutes of the day playing Ingress.
If I'm at work I only lose about 35% battery throughout the entire day. I only send/receive a total of about 100 text a day, and don't game other than Ingress. Very light Facebook use, browsing, and such.
Unrooted/Stock

Those usage times are pretty good for stock. I would be happy with anything over 12 hours right now.
I did notice bit better battery life after freezing/disabling some of the stock bloatware, but now I'm trying out an old fallback: JuiceDefender.
So far, it seems to be helping substantially (although it obviously only helps during idle times as it shuts off mobile data until the screen is on/unlocked), but I'll wait until I've had a full cycle before passing any final judgement.

run this:
https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app
for 2 days and it will start controlling things in the background based off of how you use your phone. It will manage gps, wifi, data and not allow apps that you don't use regularly run in the background.

I had heard of this app, never installed it till now though. Would you suggest ditching the JuiceDefender app, or leave it running in conjunction with Battery Guru?

I would try just that and see if it helps. It just monitors your usage for the first 48 hours so if you are running other battery savers it might not work as well.

I'm totally stock and I regularly get 30 or more hours of battery. And I don't just keep my phone on the desk all day. I get 3.5-4 hours screen on time. 10% drain when not using your phone seems like an awful lot.
I have everything off that I don't need or use. That's pretty much it. I'm also on WiFi pretty much all the time too at home and at work. Don't know if that has anything to do with it
Sent from my HTC6500LVW using Tapatalk

Yeah, WiFi doesn't kill the battery nearly as much as the CDMA/LTE radio does. Unfortunately, I have both poor signal, AND lack of WiFi at work. Haha. Oh well.
30/3.5 would be fantastic. I'm jealous.

So question, where are you finding these screen on numbers? I looked under battery and the usage part shows apps but not screen on. The graph shows when the screen is on at what point during the day but no durations are given.
