I have radio 1.20 and it seems to be working OK but in UMTS mode, the battery dies quickly and the TyTn gets very hot. In GSM mode, the battery seems to last forever. Anyone else experience this?
How quickly does the battery die? Do you use push mail? How's the signal, coverage? What about BT? The battery consumption depends on a lot of things .. some of which I list already ..
It shouldnt be getting hot in any case .. from what I know the only reason the TyTN might get hot is if you use wifi ...

Battery was down 20% in about 2 hours. push email and bt on. I've downgraded to 1.16 and will see how that goes.
UMTS, DirectPush and BT are a dangerous combo .. but 2 hrs is still pretty bad .. You should be able to last 10-12 hrs on an av with UMTS/DirectPush .. less with BT ..
Shutdown DirectPush and BT for a day and see what happens ..

Thanks. Need Direct Push, but will try to keep BT off when I don't need it.
Basically, MS DirectPush keeps a connection constantly open to the Exchange server to get any latest changes from the server ... This basically kills the battery literally ..
And if it's just emails (not too huge) .. you can probably just go back to Edge .. to save battery ..
One more thing you might want to do is download a TaskMgr and monitor the CPU Usage and Processes .. to see if you have something running in the background that you dont know about ..
I keep BT and DirectPush (99% of the time with UMTS) on all the time, and I am not experiencing the battery drops you're describing.
Are you on Cingular? and if so, which data plan? If you're using a MediaNet plan, perhaps your issue is server timeout related...
Maybe got a bad battery somehow???
I'm on medianet (cingular). So far, 1.16 is working OK. The real test will be tomorrow. Can you recomment a TaskManager?
Your issue might be your data plan. As you are forced to use wap.cingular and are thus saddled with a constantly changing ip address, you're probably timing out, which forces more polling and decreased battery life -- and there's nothing you can do about it, short of changing your data plan.
PDAConnect does not have this issue but costs twice as much.
For more info, check out Sleuth's analysis of the problem.

Interesting. Thanks. I don't seem to have the issue on GSM, i'll probably just switch the device to 3G when I need it.

Try the TaskMgr from buzzdev.net .. it's pretty good ..
If i keep f.e. skype enabled over UMTS my hermes gets flaming hot!!! The battery is completely empty within a working day en I can literaly feel the phone if it is clipped to my waistband that warm it gets even through the carrying case... Nice to keep your hands warm in the winter...
It troubled me so i do not use it any more... (umts / skype / push mail)
The phone works likes a charm otherwise...
I have a JASJAM, which is basically the same phone as my brick'd TYTN. I have the latest JASJAM ROM on it, which was recently released with Radio 1.20. Up until the beginning of last week, I could barely get 14 hours out of my phone. Cingular must have made a change to the network in NYC and how it interacts with the phone on 3G. Literally overnight my battery life jumped about 50%. I rely on 3G, Direct Push and Bluetooth at all times. I was shocked, but in a good way.
Today has been a good day. 3G, Direct Push, BT on, very little call activity but in about 4 hours, my batt has not moved off 100%. I guess i'll stick with 1.16 for a while.
Might be possible that the Cingular RadioROM is optimized for the Cingular UMTS network ..
But anyways .. glad that your battery is working better now ..
Quick update...in NYC...been off the charger now for 5.5 hours. No phone useage, but email with Direct Push, UMTS, BT and down to 90%. Very excited that things have improved so dramatically.
So after all what's the best ROM combo for Cingular in NYC? I guess a radioROM is enough, right?
Battery
I've TyTN with Good (push) service. With Good activated (GPRS always on), BT activated but Network only in GSM/GPRS I can reach no more than 8 hours. Disconnecting BT and Good about 2 days of life time. BT + Push drain incredibly battery.

"Push" in general is not your problem -- it's GoodLink that is the big battery drain...

Good morning!
Over the last week, the battery life on my JASJAM has become totally miserable. I'm just barely getting over the 12-hour mark most days, and this is with very little use, mostly just receiving emails on my desk while I'm sitting at work. The only programs running are ActiveSync and Outlook, as I use Microsoft Direct-Push with my company's Exchange server. I am always connected to 3G in New York City.
Now, this might be due to the usual crappy Cingular 3G issues in New York City. Before this ROM upgrade, in some parts of the city, my phone would constantly turn on as the network was creating some wacky reactions with the phone. Since going to the Cingular-inspired radio ROM, the screen stays off but I have no idea what's going on behind the scenes.
Anyway, do you think my battery problems are ROM related, network related or something else? BTW, I've tried two different batteries and they've both had similar run-down characteristics.
Thanks!
Mine was last loaded 3 days ago and has more than 60% left.
But i've used the phone just some times and only 4 or 45 phone calls.
And NO UMTS!

This is a problem that I have talked about before on other forums. Using 3G on the tytn will shorten your battery life about half compared to using edge. I dont use my tytn for much (a few calls, msn for chatting and email and some browsing) and I can't get more than 10 hours on a charge. When I change it to edge I can get over 24 hours.
Hollywood...
Believe me, I feel your pain. I'm using an extended 1500mah battery right now (which doesn't quite fit perfectly but close enough) and I think it should be good for about 17 hours according to the current calculation with UMTS always connected. That's enough to get me through 1 day, but it's pushing it. Do you think the next HTC rom might show improvements in battery life?
Thanks
hey CNJYC, slightly OT but did you get the Seidio battery or the one from Lionbattery.com?
Sleuth255...
I have the Mugen 1500mah version from Lionbattery.com. It is every so slightly thick which causes the battery cover to bow out maybe a millimeter or two in the middle, really not much at all. I will not go with anything larger that requires a new battery cover, as this defeats the purpose of such a nice, small device. Instead, I carry a spare or two when I'm traveling. Do you know anything about the Seidio battery?
Yeah, it has the same problem. I have a Seidio. I was wondering if the Lion battery fit a bit better.
Got it...thanks
@CJNYC and Sleuth255,
Compare to standard battery, how much more (hours or minutes) do you get from the extended battery?
Maybe 2 hours on 3G
After ur post and continious using of 1.16 radio on mu HTC TyTN for a week now i also feeling that the radio seems drain battry fast....the situation is that i generelly receive/made 10-15 call a day of total 1 hour or so duration....30-40 min of game play and may be more less 10-20 min of chatting and browsing in my tytn and i can get upto 2 days easily with 20-30 % of battry life left in gsm 900 mode ooo and always pushmail activated and of avarage 8-10 e-mail receiving and sending...
but after 1.16 radio i thnk i can go upto 1.5 days with same battry left and the senerio is the same regerding my usage pattern....and most of all before that the battry used to discharged 10% overnight at maximum when i was sleeping with 2-3 mail receiving through pushmail and of course no other use...but now it seems im loosing 20% on same time period...
i think i need to do some more testing regarding this battry life probs...any other feedback is really wanted...
thanks
Sajib...
Thanks for your posting. The 25% reduction since going to the 1.16 ROM that you reported is basically exactly the reduction I'm seeing here on 3G in NYC. Everything else about the ROM is better, especially how it handles weak signals and not forcing the screen on, but if I can't get a full day out of it I will probably downgrade. I'm just holding out for a new HTC ROM, but I'm not sure I can wait any longer.
Any other experiences with the 1.16 Radio ROM?
Thanks!
I have some problem... Dunno is because of 1.16 Radio ROM or my application. But i did Hard Reset & Install bk the Application that i use previously. The problem still same...
Let say i didn't touch my phone (Button) for about 30min and more. The phone will like go to Searching Mode.....wat i did is turn to FLIGHT MODE, then OFF the FLIGHT MODE. Then the phone only will get the service provider. After that it's ok. ...
Anyone encouter this problem b4?
which ROM has the best battery life,i have a friend and to him features and speed are irrelevant- just wondering which rom on these forums has the best battery life- in my experience its PROven 2.2
I'm just going to jump in here before you get flamed all to hell...
There is no "Best ROM for battery life." It depends on your radio, your location, your usage habits...
Have your friend try various ROMs until he finds one that suits his needs...

Battery Life Reco
I would think that ROMeOS or Elite project, since they are the most actively developed and publicized, and I know they have very recent drivers, might be best for your friend.
Also, they would get a lot of complaints if battery life dropped off. Same goes for a recent stock ROM, so there's that option as well.
A crucial note for battery life:
Use Advanced Config to enable the "3G" on/off switch in Comm Manager. Also, have your connections disconnect after 60 seconds of inactivity.
I get 1 day of battery life with normal usage when I leave HSDPA on, where as if I stick with EDGE, I can get 3-4 days. That's with IMAP e-mail retrieving every 15 minutes! Brilliant, if you ask me.
Note: I used a BlackBerry 7290 that worked on GPRS only this past summer, and its battery would last for 7-10 days! The faster your connection, the more quickly your battery drains. I've only witnessed few exceptions, one being an LG CU515, but I'm convinced it just turned off 3G without notifying the user to save battery.
I would love it if my TP kept to GPRS until I opened a browser or hit send/receive on my e-mail, (ideally using EDGE here, perhaps HSDPA for attachments) but I think that would be fairly hard to configure/no one has done it yet. Also, it would suck to receive an important call (phone interview, for example) and be stuck with non-3G voice and thus degraded quality. However, I hear 3G voice tends to disconnect more often than non-3G (while 3G is turned off) especially when moving from cell to cell, and as I recall basic GSM call quality is usually pretty good.
"Which ROM has the best battery life?" is a question we cannot answer for you. Everybody on here does something different from the next person, so results will ALWAYS vary.
The best way to control battery life is to try different radios until you find one that performs good in your area. A radio that doesn't have to work [very] hard to find a signal will not drain the battery as fast.
So, I have had a serious battery drainage problem, like most of hd2 users with wp7.
My battery usualy run max. 24h!
Now my phone run 2-3 days without charging.
I have just turned off connection with xbox live
So, go to the settings -> applications -> games, and turn off "Connect to Xbox Live"
I have 3G off
Data connection on (but mailbox, shares, weather ect. is updated manualy)
I hope this will help you...
Interesting will give it a go..... I have to say I beleive this and other 'solutions' may be solving part of the sympton and not the root cause BUT if it helps that's always good news until the chefs can get to the bottom of it!!
Thanks will let you know.
Cool cool
I already did this now.
Will also check it, and provide feedback.
Battery life is a bit of a problem, but atleast i have a car charger
I will give it a try.
3G on
Data connection on
its work this solution ?
I think it should work. I checked battery dainage with Xbox on right after turning phone on after sleep - about - 42 mA. So without use of the phone max time is less than 30 hours. But if Xbox is OFF current is just 5-7 mA. Means 6 times less on stanby!!! Will give it real timing try. Used Battery tool to measure current.
hello
did not work for me
It doesn't work in real life. After start some apps and close it current returned to 42 ma forever.No more 5-7 ma. Only turning on Airplane mode gives 2-3ma standby. So all bad battery life comes somehow from radio is too active.
Hello all.
I hear that if u change the radio version to a down one you have more battary life ..is it true ? there is anyone that tried that?

From my experience (only 3 days rooted LOL) you have to find radio that works best with your carrier. Better reception will stop phone trying to find masts, hence improving battery.
Sent from my HTC Desire using XDA App
I don't see any problem with battery draining. If it gets you over the day, what do you need more. Over night you plug it in.
I have all switched on (location too) and no problem with music maybe 1h, reading mails, checking facebook several times surfing internet and news. I would even say its better than WM 6.5 doing the same, at least the same.
I think battery draining is not hd2 problem wp7 is the problem
the real solution for batery is - turn on 3G
try
batery life is 2 days with many calls, play and others.

It is definitely problem, comparing with all android ports where battery life is x2 more longer than in this "simplified" WP7!! Battery is dead in a half day in a standby is normal for you?
I solved my battery calibration issue by installing HTC battery tool, it fixes the calibration of battery so correct full charge is 100% and correct no charge is 0%. Give this a try, I am sorry I cannot post the link but I found this app on XDA too.

ok im running HD2O_1.04_DFT_LEO70_RELEASE and WAS running radio 2.15 and after 3 days testing and very poor batter life with registry fix, i decided to change my radio to 2.12. and so far after 7 hrs of testing ( full data, 3G, and internet browsing + youtube here andhier) my battery is still 3/4 change the radio it take 2 sec. to do.
with the old radio i was using, i went to work at 6a.m. got off at 3p.m. and i only had 1/4 left. with radio 2.12 i still have 3/4 and i used it more because im no longer at work.
try it good luck it worked for me
i will post another update around 6p.m. pst.
Just an update.
So I got the SGS2 last nite, about 5pm.
From 5pm to 8pm, I did send 3 short gmails and 2 sms.
Also tap on myATT to check the data usage once.
Receiving one phone call.
From 8pm to 12pm: plugging to charge, fully 100%. Unplug and power OFF @ midnite.
9am in the morning, making a 25' phone call.
10am, check myATT again and it showed I have consumed 11.01MB
Really???? From 5pm yesterday to 10am today with few emails/sms/checking myATT once and it already 11.01 MB???? Heck. Grrrr!!!
After 11:30am, turn ON bluetooth and paired with headset, made another 2' phone call via bluetooth, then turn bluetooth OFF, also turn GPS OFF.
Note: Wifi has never been turned ON.
Since then til now, 4:22pm EST, no call, no browsing, but receiving a lot of gmails (via ATT network since wifi is off), phone showed 6h53m battery life left.
With those activity listed above, I think the battery is weak.
We can indeed turn off both wifi and mobile network and still able to make/receive calls or send/receive sms. This will help save a bit of battery. That's good.

You say you got the phone 5pm last night.
Your phone's battery needs to be cycled for 2-3 days before you can even get close to an accurate summary of battery usage.
Charge the phone until the battery is full, let it discharge with normal usage
3-4 times and after that you will be able to tell how good or how bad your
battery drainage might be on your phone.
Also it's a lot more accurate to test battery drainage if you conduct the
tests BEFORE you install any apps. Just use the phone STOCK for 3-4 days.
He also didn't say how much he was polling for email. Display settings?
And, as the poster above, you need to cycle the battery several times properly.
Nah, no need to cycle battery on most Samsungs, we don't have fuel gauges that need calibration.
A device needs to sit on the shelf for a VERY long time to develop a passivation layer.
Probably just typical "new user playing too much" or "user installed a crappy app like Skype almost immediately".
Although the high data usage is interesting - either Market updates of a new phone (possibly even downloading an OTA update), or you're on UCKH7 and the AP Mobile widget is acting up already.
My highest usage all last year was 400 MB in a month, and that involved quite a bit of tethering my Galaxy Tab 10.1.
Eh, I have an unlimited plan but 400mb isn't all that much. I have no idea how you did any sort of tethering without passing the 1gb mark. I don't stream very often, but will use Pandora or the AT&T Uverse app for college football occasionally. I average about 1gb or so, and have gone up to 4 (although that's far from normal for me).
I work for AT&T and the average user seems to consume about 500 MB in data a month, so if you're on the 200mb plan, you better have WIFI at home / work / school or wherever you spend most of your time.

Whoops wrong button, anyways, yes there is a bunch of crapware installed on our phones, check out the list of known battery drainers and see if you use any of those. myATT takes a while to update, and its much easier to just type #3282* (data) on your dialer and hit call. Also, wifi would be preferred, as typically it uses less battery (at least thats what I see, especially with any kind of data). Disable automatic updates of alot of things such as apps, weather, stocks and whatnot (removing widgets also helsp), and first time, especially if you linked your facebook, its gonna download and sync all of your contacts and their profile images. 200mb is very restraining if thats what you have...

First of all, I am a totally newbie to smartphone, prior to 5pm on that day, I was still using the antiqued flip phone . However, I am familiar with Android OS a bit since dealing with the B&N NC. I tend to rip the NC apart w/o worrying anything, worst case, restore it confidently; SGS2 is on the other hand, it is a must have device, and I admit that I'm somehow afraid that I will mess it up. That's why still keeping it stock for now. But I eye to use UnNamed ROM along with Entropy512 DD kernel, it is on my list.
Secondly, to answer akira, I have no idea how much I was polling for email, as I said, I left H+ on all the time, so I got every single gmail that sent to me.
Display settings? you meant brightness? or display the Phone Status?
@penguin,
Yes, it's just like new lappy, tons of pre-installed crapware. I was thinking either I manually uninstall them or wait until out of warranty and put the UnNamed or any great custom ROM on it.
You know what, anytime I check myATT on the SGS2, it consumes data, so I found a cheating, sneaky way that checking it using wifi (not using ATT network) or using my NC . The reason I am so focus on it 'cuz I only have 200MB plan, if I use much more than that I will switch plan later, but for now, 200MB plan and using wifi.
You do know you can return to 100% complete stock right? As long as you read and follow directions, there's a miniscule chance of hurting this device, it's very resilient.

Thanks for your note, m8.
And honestly no.
Like I said, I just own a smartphone for 2 days, so admittedly I never set a foot (or should I say a finger ) on this forum until now. I am still on the reading/learning curves. Many devices have their different capability, for instance the B&N NC is virtually unbrickable so we (NC users) do have a lot of fun whacking it. If hitting problem, XDA is here for help .
SGS2 is a phone, if we're not confident and if we mess something up, we freak out or panic. hehehehe, at least that's on my mind
The reason I said "no" above because I read some posts and they said only 95% back to original, not 100%. Is it still true?
Anyway, big thank for your confirm.
Alright, so I went online and checked out the data usage.
At around 4:57pm, Internet/Media Net from phone took up 11345KB in one shot.
Don't know what that was
Maybe activating process? Getting H+ to work? Initial setup? Whatever, that's what it was.
The other Internet/Media Net from phone @9:03am and 5:14pm, don't remember what I did? Maybe 1 gmail and 1 sms? Either way, 1 of them took roughly 2MB. Woww.
Adding image
You should really get 2gb on your first month to see how much data you use and not risk paying overages, after that you can decide what to do with how you want to use your phone.
I'm not worry, m8, I'm more like an old fashion guy who not using phone internet much. I am pretty much working and/or wifi accessing all the time
Just try to see how much MB I do use a month since with wifi, I never ever pay attention.
Just another update.
A few days ago, phone was at 33% battery life around 11pm, left H+ on overnite with screen turned off, in the next morning @ 8am, checked, phone was still at 33%.
Last nite, phone was at 87% at 11pm, left wifi on (no H+) overnite with screen turned off, this morning @ 8am, it only has 81% left . Recheck at 9:30am, it's 79%.
I thought wifi consumes less power than 3G, left alone 4G/H+, hmmmm
H+ is only active when transferring data. It's basically using multiple connections of 3g to get faster overall connection, so it was in 3g all night. Also you should try with the battery fully charged and check to make sure your phone was not awake. I know that I drop 1 or 2% overnight with either wifi or cell data.
Thanks, m8
Good to know.
At first, I always think 3G consume more power than wifi. Then reading posts, seems to be 8 out of 10 people claim wifi consume less 'cuz shorter Tx (like wifi at home) distance, final answer from them is "testing yourself" so I did and it got me a surprise that in my case, wifi seems to use more.
Learning every day.
Well every person is different. I live in an area with low signal, so it usually takes a couple of tries to actually get the data, and I have multiple apps checking every 15-30 minutes (but phone still stays in deep sleep). The thing with android is that everyone is different and has different apps that affect battery life.
Update:
Last nite, 01/05, phone was at 87% at 11pm, left wifi on (no H+) overnite with screen turned off, this morning @ 8am, it only has 81% left . Recheck at 9:30am, it's 79%.
Beside 20' talk via bluetooth (after than turn off bluetooth) no other activity in the morning until noon.
Turn on wifi, keep it on until 6:30pm. Did download and install a few apps w/i 15' max, battery at 62%.
At 6:30pm, turn off wifi, turn on H+, turn on gps, turn on bluetooth.
Another 25' talk via bluetooth while driving along with Maps GPS on.
Arrive home, phone has 45% left.
Wowww
With very limited usage, the phone lasts only about a day
Woman, battery drained too fast, grrrrr.
With my normal usage, it probably last 4 hours.
I don't know it is what it is or I actually has a defect battery pack?
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.
