I would like to collect cell standby data from you. Cell standby is much too high, i have 1% per hour even under optimal conditions. Some users have much more and are satisfied when they reach 1% but i think this is too much. SGS1 and SGS2 are below 0,5%.
Can you post
time on battery,
remaing capacity in %,
cell standby in %
and calculate the consumption per hour:
(100 - "remaining capacity in %") * "cell standby in %" / 100 / "time on battery"
Sample:
time on battery = 5,5h
remaing capacity in % = 84
cell standby in % = 40
(100 - 84) * 40 / 100 / 5,5 = 1,16% per hour
//EDIT//
I build a google sheet where we can enter these information and which then calculates the average stanby drain:
https://docs.google.com/spreadsheet/ccc?key=0Ambt0PkdLr7BdEJ1alptQ2M1bFlLbm11aVdtNmtIY0E
Maybe that helps to identify those configurations without drain.
Hi,
I think this is a good idea, but it would be good to post your current ROM, Radio and Kernel plus the country and provider.
All these points could influence the cell standby. I am on 3G an have medium to good reception.
ROM Omega 5.2
Radio XLF2
Kernel Siyah 1.2.6
Country Germany
Provider O2
Standbydrain
time on battery = 4h
remaing capacity in % = 75
cell standby in % = 41
(100 - 75) * 41 / 100 / 4 = 2,56% per hour
Time on battery 6:30
stanby cell= 58%
remainig capacity=67%
ROM Foxhound 0.3
Radio XLF2
Kernel Siyah 1.2.6
Country Luxembourg
Provider Tango
(100 - 67) * 58 / 100 / 6.30 = 3,03% per hour

How unfair life can be
Cell standby seems to be
1) A modem firmware failure for those who actually have bad cell standby battery life. This seems to be caused by not entering low power mode on non active connections or switching to fast/often between the power modes.
2) The batteryprofiles.xml populates the cell idle entry with 33mA as power drain as opposed to 3mA for the S2 which has the older version of same type of hardware modem. This is absolutely retarded as the actual drain is not really that much and being reported much higher than it is.
I personally am running on 2G which is more than enough for chat, email and notifications and switch to 3G whenever I need to manually or am on Wifi. I am still on my first charge since I have gotten the phone, and I'm at around 40 hours lifetime with 4H screen time with 33% battery left. This is with around 20 reboots while flashing and testing my kernel, and playing with the phone. Over-night (8+ hours) I lose about 3%.
no cell standby issue in CM9 by the way guys

So what you are saying is that it is just a miscalculation? Then the voltage would still show up correct.
Any idea where to find the battery voltage?

Yes that's what I'm saying. The whole battery statistics page in terms of percentages is absolutely useless. Not only are the modem values completely ****ed but the CPU accounting is dead wrong, the values are the same for 1400-900MHz as the Galaxy S2 values for 1200-200, with all the steps below 900MHz being reported as the S2's 200MHz current consumption (55mA). You can absolutely not rely on any of that data for now as it is absolute hogwash.
What does the voltage have anything to do with it? You can't do anything with the voltage value alone, other than maybe estimate battery charge level. Use Battery Monitor Widget if you still want to see statistics.
The Voltage would show if the battery really discharges that fast or if it just is a miscalculation, as you are stating.
My phone is dead after 20hours, no matter how I am using it. The only thing that helps is Airplane mode, but that way a phone is kind off useless.
No wifi, no app and not even the screen are killing my battery. There has to be a culprit and I am guessing, as maby others are, that it's a bug in the radio.

Battery discharge of course it correct, I'm just claiming that the battery statistics and break-down is absolute nonsense. I suspect that it is fast-dormancy, try idling it on 2G/EDGE and see if it's the same.
Ah, now I am getting you.
If it was Fast Dormancy that would explain why two identical setups in two different countries, with different providers are having such different runtimes.
In 2g mode fd is disabled, if I read you right? As I am wifi areas most of the time, 3g is not that important to me. Worth the try.

FD doesn't exist for 2G. So yea, basically disabled.
Added my actual data and i'm surprised. No one has an acceptable power consumption for cell standy. I hope Samsung fixes the problem.
The last hours I was running on 2g only and it didn't do any good.
Experienced nearly the same amount of battery drain than before.
I will switch to another Radio, and will keep an eye on that drain.

At night i have only 2G because in my home where the phone "sleeps" no 3G signal is available. The signal is much more worse, only 1-2 bars, but the battery consumption is even better than with 3G. In 8 hours of Standby only 2-3% battery like it was before with my SGS1. Seems to be only a 3G problem. I checked logcat, but i don't have the fast dormancy problem. I think with 1% per hour with 3G i have a very good performance but in comparison to SGS1 its worse.
Your phone has to run a whole setup, authentication and connection procedure with the antenna each time data network is cut. However when the data network is open (especially on HSPA frequencies) it drains the battery.
So FD is a 3G feature (HSPA-Versions being different extension levels) which basically tells the antenna that your phone will now disconnect the data connection but the antenna should remember him and the state of all TCP connections.
Periodically your phone will power up the data network through a very short and speedy handshake procedure which resumes the old data connection and ask the network whether any new packets have arrived. If so, it will accept and process them and keep the data connection open for new incoming/outgoing packets until it goes back to Fast Dormancy (IDLE) mode.
The network/antenna of course has to store any incoming data packets until the phone polls it so there is a measurable multi-second delay until the data is effectively received by your phone.
The exact polling frequency is defined by your phone's internal database of network operators and is e.g. for all luxembourgish network operators 5 seconds. Therere is no single 'good' value since:
- the network has to store the data. If your phone polls too slowly it might drop the data packets or even close the connection, forcing the phone to run through the full procedure again which causes huge battery drain. (This is also true if the network _SHOULD_ support FD but in reality does not)
- the incoming data packets are delayed by up to X seconds, X being the polling frequency. So you might e.g. only see incoming chat messages several seconds after them having been sent if the phone is in IDLE mode.
- too high polling frequencies put a high strain on the network (to the extend that they might refuse your mobile to reconnect for a certain timespan) and kills your battery fairly quickly.
Furthermore FD only works for incoming data packets, not outgoing ones.
If your phone sends a message, it will directly go to fully-awake 3G network until fast dormancy kicks in again after a certain idle period.
Now, basically FD is a very good solution to 3G's battery drain, however it only works if your phone does not send data and does not constanctly receive data. (Additionally of course, the FD network setup must be correctly configured with sane values... I've seen carrier-provided setups of 1 second Fast-Dormancy interval)
If you have apps which keep data connections open and constantly send/receive small amounts of data (e.g. Skype, ICQ, Msn, Facebook, ...) FD is more or less worthless for your setup and might only cause a huge battery drain.
Furthermore at least my provider (Tango, Luxembourg) sometimes shows bad cases of antenna hopping when waking up from FD which drains the battery even more.
(Antenna hopping is if the antenna tells your mobile phone to connect to an other antenna because it's overloaded or it knows that the other one has significantly more capacity available. However if not properly managed by a supervising instance, this may cause several antennas to play ping-pong with you and keep moving you to other antennas)
2G on the other hand doesn't know what FD is for a very simple reason; it uses the same frequencies for data network and voice. The latter has to be connected at all times anyway, so keeping the network connection open only causes insignificant battery drain. (As long as the device is actively sending/receiving data the battery usage will of course get higher)
So if you want your phone to be connected at all times (Chat, Push notifications, Emails, ...) you'd keep it in 2G. But due to 3G having a better KB/W ratio and being MUCH faster, you should switch when browsing the net.
There is a (paid) app for automated 3G/2G switching when the phone is idle which additionally can enable/disable Wifi when you're in range of a configured network based on it learning your exact location from signal changes of the coarse network-based location.
That app is called Juice Defender Beta (you need the 'Ultimate' donation key to unlock all the features) and so far works flawlessly on my phone.
(Additionally it can automatically dim the display below the minimum-brightness which is cool at night )
If the phone has a very high network drain in 2G too you most likely are either constantly receiving/sending data (e.g. Skype, I recommend using IM+ Pro and configuring it with Push notifications when in the background) or using an Exchange account which seems to have a battery-drain issue in Samsung stock firmwares.

Is it normal that I can barely last a day on a charge with this device?
My GSM devices could go at least 2 days without charging. I don't mind charging every night, but right now it would be dead before my day is over if I don't charge it at my desk too. That can't be right?
I ran bunch of test on this before i decided to keep it. One day I set it up without anything running. from 8am to 8am the next day the battery power was still 100%. Another test I did was playing audio. it went about 6 hours and I still had 20-30% battery remaining. it was loosing a about than 10%-15% per hour.
The problem is once you go on data mode it stays there and doesn't come out when it doesn't need it anymore and that drains the battery super fast. These type of programs:
-weather check
-Windows Live (for maps and searches)
-traffic
-e-mail (if you have autocheck on)
When you see the data mode (the two arrows that replace the tower icon) appeaing go in the comm manager and disable the data mode. That's obviously not a permanent solution but until figure out how to have the programs that use the data connection to return the radio to audio mode when they are done using the data mode, you can save some power.
I hope that helps.
The Mogul's battery life is definately very sensitive to the software you have running.
When I first got mine, it would barely last me 8 hours of light usage before getting the critical battery alert.
A week or two later, after a few charge/discharge cycles and a ton of configuration/software tweaks, my battery lasts all day, and is only down to 60-70 percent when I go to plug it in at night
Just to extend on what was already said, if you have outlook set up to sync automatically, set it to 5 minutes instead of "as they arrive." This made a big difference for me.
I use BatteryStatus to monitor my battery drain, and it drains at about 30-40 mA when the screen is off and when it is on and dim, around 85-100 mA or so when nothing is really active and I am at the today screen.
From my experience, the thing that affects battery life the most is the signal quality of the phone/data service. If I'm in a location where the signal is 0 or 1 bar, then the battery will drain to 20-30 percent in about 4 hours. With a strong signal, the battery only goes down to 50% for the full day.

Right, so I've established that my phones lasts more than a day just fine if I'm in good service.
But is this "normal" for a CDMA phone to do? My old GSM phones could go into "searching..." for hours at a time and still have more than 50% at the end of the day. I know CDMA phones use a little more power then their GSM counterparts, but I didn't know it was THIS bad! Or is this just a bug in the system that can be fixed in the future? Being my first CDMA device, I can't tell yet what's normal or not.
GSM and CDMA RF transceivers manage power output differently. What's ironic, is that in theory CDMA handsets are suppose to manage battery power better than their GSM counterparts, sincd CDMA tranceivers continually vary the power output to match the cell tower coverage, while GSM tranceivers power a steady-state output.
Now that's in theory.... I've read numerous ancedotal articles that have compared sibling phones (same model, but one is GSM and one is CDMA) and the GSM for whatever reason performs better in terms of battery life. I know.... doesn't make sense. Two theories have been proposed by folks, one being the actual coverage for a particular area and the other that Qualcomm just basically did a poor implementation of the CDMA design in their chipsets (which are widely used by everyone).
Wish I had a better answer, but I don't have any hard evidence at the moment to say it's definitely this or that explains the difference.
There is also a configuration issue whereby data connections are not terminated after an application is done with it. Email automatic Send/Receive being one of them. Shuting down the data connection through HTC's Comm Manager doesn't solve it either. I installed this software that allows you to manually enable/disable data connections, mapped it to button 5 and have seen my battery life almost double. This of course defeats automatic email reception though.
I have changed my battery drain from 90% a day to just 10% a day by turning off bluetooth discovery! I can leave bluetooth on all day, but by turning off discovery, it seems to save a tremendous amount of power.

This is a great thread. I always had the activesync to sync as items arrive. I bet this should help a lot. I'm going to change my weather options next. dont need constant weather updates all day long.
I've noticed that my battery life is draining somewhat faster than seems reasonable...
After 7 hours away from my charger I'm at 36% remaining, and frankly haven't used the phone much today. Two 5 minute calls and a bit of playing with email.
The battery status shows that 'Android OS' is using 43% of the battery at the moment. Next after that is the screen at 19%.
Is that normal? Or have I installed something that is draining away at it? What is the best app to identify the malevolent drainer?
Many thanks in advance!
my "Android OS" is always somewhere around 2-3%. You running stock build? mebby reboot the phone and check again?
Stock build.
Have rebooted and killed most of the apps that came along with the reboot. Will watch it over the rest of the day and see if the problem repeats.
Screen usually 70% Android 2-3%.
Mine was horrible then i saw an app G backup.that I had on auto eating up 40%... changed it to manual and eliminated that and an overheating issue... Wierd.
I have been having issues with battery life also. My cell standby was using 65-85% between charges. It would go down to 20-25% battery life after 7-8 hrs with little to no use. I did a factory reset and everything was great for one day, cell standby dropped to about 4%. I added some apps, recharged overnight, and in the morning after 1 hr battery was down to 80%, cell standby back up to 75%. not sure if it's an app i installed or not. At home i have been using a different micro usb charger, not the stock one. I'm wondering if that could be the cause. I did a 2nd factory wipe this morning and now cell standy is back to 4%. I'm going to only use the OEM charger and only add apps 1 at a time to try and narrow down the cause.
do you have the 3g problem?
my guess is ... if your phone keep switching between 3g/edge or umts/hsdpa
you keep using wireless radio and thus consumes much more power
no, I've never had any 3g problems, other than only getting a max download speed of about .8Mbps.
I called HTC about the high cell standby usage and they suggested - turning screen brightness all the way down, turn off GPS, turn off bluetooth, turn off wifi, etc... If I have to have everything turned off so my battery won't die then what's the point of having an otherwise awesome phone. It's been an hour now since unplugging and cell standby is at 20%, battery life at 98%. I guess we'll see...
Battery issues are almost always due to apps (or services) running, especially ones that are constantly using a data connection.
That's why Apple don't allow the iphone to run anything in the background ;-)
If it was fine after reset and then bad after you added some apps then you know one of them is to blame......
My nexus one has been unplugged for 24 hours now and is at 66% (fairly light use in that time to be fair).
it's possible that android synching could cause usage to spike to those levels, but that shouldn't be happening very often.
I leave syncing on all the time and my phone is easily 14 or 15 hours to get to 20% with what sounds like heavier usage than what konsta is reporting.
I read some guy solved most of the battery issues by turning off GPS. I'm now following this practise after a full charge from completely dead to see how it goes. I normally have to charge once per day, I do use the phone quite a lot, not much for phone calls though, twitter, facebook, sms, tech news etc!
I think that my "Android OS" drain must have been a one-time event (hope so, anyway). After my reboot I'm now up to cell standby as my primary usage. I've spent a fair bit of time in the last few hours in patchy signal areas, so seems fair.
Will see how long it lasts tomorrow.
I agree that the GPS seems to be the biggest battery killer. Completely drained my machine in next to no time when I was playing with Copilot live.
I am actually impressed with the battery life on the n1. I can keep GPS on and use it, playing games on the train and answering emails and calls all day long with seesmic constantly running and easily get through the entire day. If I don't charge it overnight I will be about 15-20% remainig in the morning. I have stock android os on an unlocked n1.
Power drain solved....
Hi every one.
My battery life to was abismal, that was until I read this over on Modaco.
GSM 2G+3G ("WCDMA preferred") drains battery over 5 times faster than exclusive 3G ("WCDMA Only")
Average battery drain / hour when phone is idle with screen off:
1-Standard shipping mode WCDMA prefered, i.e. both 2G and 3G enabled, Wifi off): 10% / hour
2-Alternate WCDMA Only mode, 3G exclusively, no Wifi: 1.7% / hour
So I tried changing the phone settings from WCDMA prefered to WCDMA only. WOW battery life instanly better!!! 3G still works and phone OK.
To do this enter *#*#4636#*#* on phone dial pad, select phone information, then scroll down to selection box, change set preferred network type to WCDMA only. Switch phone to airplane mode, then switch airplane off and watch your battery performance increase by 300% plus...

Hi rockky.
No I am on Orange, I usually only get a full strength 3G at my works and not usually at home, however since getting a Nexus 1 i now get a limited 3G at home..
after uninstalling mobile defense and city caller id my bat went back to normal.
I noticed pretty good battery improvement when I turned off GPS (only turn it on when I need it).
Hi -
I've had my HTC HD2 a few days and although I'm happy with it's features, I'm really frustrated by the poor battery life. The first day I used it the battery was dead within under 12 hours from me starting to use it, and at the start it was fully charged. On this first day I did have email and weather etc on auto check though.
So last night I disabled weather, set email to manual checking and disabled a few other things, but did leave HSDPA and 3G on. There was a slight improvement today but not much, the battery lasted the full 12 hours, but with only 2% remaining.
Both days I don't think my usage was very high. I'd maybe had 10 minutes of phone calls, sent around 10 text messages, listened to 45 minutes of music, checked one or two websites, and played games on the phone for about 15 minutes. Imagine how it would be when I need to make several calls in a day.
I have searched the forum for tips on improving battery life but the main suggestions seem to say that I should disable HSDPA and 3G but one of the main functions of the phone is internet usage and I don't see why I should how to switch to manually putting these settings on and off each time I want to use the internet, just so I can get a longer battery life - the battery should be able to cope with moderate usage!
Does anyone have any further suggestions?
Thank you
Look for an application called 'Bandswitch', it can disconnect idle connections. THis way 3G won't be enabled when you don't need it, should save some battery.
Disable automatic screen brightness and set it to something like 30%.
Disable location services and stuff.
Give the battery some cycles to reach full potential.
But of course, gaming, internetting and listening to music will drain the battery faster. It lasts about 2 days for me with moderate use (some internet, some playing around, etc) which is pretty fair imo.

I'll give that a try. So will it automatically enable it when I start browsing the internet or something?
I already changed the screen brightness and disabled location services though. That didn't seem to make a big difference.
And how much difference does giving the battery some cycles make?
Thanks.

Sorry, but it doesn't work that way
Bandswitch can definitely do 2 things- it can disconnect idle connections, which will reconnect when needed, but this won't switch the transport between 3G and GSM, and has little effect on battery life
Or it can be used to manually change between 3G and GSM, using whichever is selected for its current transport and then autodisconnecting if required. It is the action of switching to GSM which has the most impact on battery life, but there is no way to switch automatically between to 2 as it needs a phone radio off/on to execute the switch.
Poor 3G signal conditions will hammer the battery because the phone will continually hunt for the strongest signal and switch constantly between modes. If your 3G signal is less than 2 bars I'd suggest switching it to GSM until you are in a stronger signal area. Do this by going to Phone/Menu/ then scroll down to Band and from there switch between Auto and GSM. If that makes a difference then you could install a small utility to make the switch easier to access.
seems very odd, mine was fully charged around 11pm last night, have sent around 20 texts, 20 mins calls, had wifi on, done some browsing, abit of sat nav and its on 68% 20 hours later.
I get at least 24 hours with moderate use. Most of the time i get around 30 hours.
I have weather and peep updating automatically + email retrieval at every hour.
When I first got mine it was lasting less than 12 hours too.
Now I'm on ROM 1.61 and have the following settings:
HSDPA disabled
Weather update every 3 hours
Twitter updates ever 1 hours (though it actually only updates when I scroll to the Peep tab)
Facebook auto updates - Off
Stock auto updates - off
Bluetooth and Wifi off unless needed.
Screen brightness - 30%
Haptic feeback, Vibration - off
Push Email - On
I'm getting over 24 hours of life out of a full charge now. I have got the push email set to manual updates only during off-peak hours ie when I'm sleeping. During the night the charge drops around 1% per hour. It was at 47% when I went to sleep last night and was 40% when I woke 7 hours later. This seems to be typical overnight drop for me.
Over my first few days of tinkering and setting up I found the battery drain to be massive. Once you settle down to regular usage it is a lot lot better.
However, just to be careful, I do now have a desk cradle at work so I can charge my phone if I have to.
Prior to my most recent hard-reset I found that if I left the phone in stand-by over night, with it checking for email every 5 minutes, and weather every 15 minutes, the battery would go from 100% to zero in less than nine hours. And that's without using it at all! As an experiment I tried turning off everything that could possibly be using the data connection, and turning off 3G, so nothing was running at all except the phone in 2G mode listening for calls and texts. It still burned 20% of the battery overnight in stand-by.
Since doing a hard reset, if I repeat the second experiment then I find that overnight battery drain is now only 4% - so clearly some piece of software that I had installed prior to the reset was hammering the battery even in stand-by. Quite what it was, I'm not sure yet. (My current prime suspects are the task manager and 1% battery status icons).
If you're having battery drain issues then I suggest doing a hard-reset and then not installing anything remotely controversial for a day or two to see if that sorts out the drain. If it does, then you can start reinstalling things gradually to see what difference each one makes.

Sorry, but it doesn't work that way
Bandswitch can definitely do 2 things- it can disconnect idle connections, which will reconnect when needed, but this won't switch the transport between 3G and GSM, and has little effect on battery life
Or it can be used to manually change between 3G and GSM, using whichever is selected for its current transport and then autodisconnecting if required. It is the action of switching to GSM which has the most impact on battery life, but there is no way to switch automatically between to 2 as it needs a phone radio off/on to execute the switch.
Poor 3G signal conditions will hammer the battery because the phone will continually hunt for the strongest signal and switch constantly between modes. If your 3G signal is less than 2 bars I'd suggest switching it to GSM until you are in a stronger signal area. Do this by going to Phone/Menu/ then scroll down to Band and from there switch between Auto and GSM. If that makes a difference then you could install a small utility to make the switch easier to access.

Oh, I misunderstood it then... thank you for clearing that up!
It's very interesting, to see the number of people who have battery draining problems. I have the french SFR ROM 1.44 and since the beginning found my battery life satisfying (I didn't expect long life, as my wife has to charge her iPhone every night).
My battery lasts in heavy use 24h (though it can go down to 18h when using internet by 3G/HSPDA for long period like 1h or more) and under "normal" daily use (checking e-mail regularly, 20 min phone calls, sending some SMS, 30 mins internet, 45 mins playing around / listening some music) around 1.5 days.
My settings are:
3G/HSDPA enabled
Weather update every 6 hours
Stock auto updates - every 8 hours
Bluetooth and Wifi off unless needed
Screen brightness - auto
Haptic feeback, Vibration - off
E-mail check: every 2 hours (POP3)
Faulty batteries? I think not....
Whilst I'm a master of google searching, I get worse results using the search facility on this forum than just using intuition.
Anyway, I just wanted to add my comments on battery life after owning a stock 1.43 phone from Vodafone UK. I was getting less than 8 hours life with everything on auto and making just a couple of shortish phone calls and a couple of quick browses. The rest of the time I was in standby and I thought that my phone was one of the worst out there. I had also installed Skype which I had running in the background which sometimes causes the phone not to go into auto-standby even though it would dim normally. I also noticed that I was in a very weak signal area and that my phone was constantly switching between 2G/3G/H which I understand can consume a lot of power. Also, I had stopped using wi-fi to see if that helped.
After reading a million threads, I decided to conduct an experiment last night. Usually if I charge the phone before going to sleep for 8 hours it is down to 70% when I wake up having been left in standby. So last night I disabled everything. Turned off 3G, data connections, My Location, Weather update, Stocks Update, FaceBook login, e-mail updates, Skype, bluetooth, wifi. In fact absolutely everything I could find that could be turned off except the basic 2G phone itself.
Guess what, I wake up 8 hours later... 96%.
16 hours later.... 81% with very light use.
Now I'm going to have to spend many days playing around with different settings to see which apps or functions are gobbling the power. I have a nasty feeling that the weak signal is half the problem
So cheer up! It's not ideal, but this is a brand new, smartfone with bugs - not a Nokia 6110. Higher capacity batteries and ROM updates will come. In the meantime you just have to figure out what is sucking up the juice on your HD2 and disable these functions if you don't need them or when you are not using them.
Good luck and enjoy it! The coolest phone around...

Hello everyone,
like the majority of the owners of HD2, in order to optimise the duration of accumulator charge, I use Band connection control programs , to pass in 3G only when it is necessary. Thus, I have:
- phoneAlarm: to force the 2G mode the night, and also for differ quiet mode if I am in meeting, etc…. In particular, in the case which interests me there, I force the 2G the night and asks to pass to 2G the morning.
- WMlonglife (version for HD2): which normally loads himself to make the effective switch 2G towards 3G or 3G+ if an application program requiring it is launched, and otherwise to remain in 2G. It should be noted that WMlonglife has two applis, one for the configuration, and to make manually changes 2G 3G, WMbandswitch.
- recently, I tested Bandswitch v2.8
I meet the following phenomena, and I would like to know if others also have them, and/or if there are parameters to change so that it goes better.
Point A: Already some question about the icons of the bar of state in top.
There are always two icons side by side. Tell me if I interpret them well.
one with a letter: G= GSM, E= Edge, 3G = 3G, H = 3G+
This letter tellsonly that this kind of network is available, but it does not say that one is actually connected there. Is it well that?
To know in which mode one is actually connected, it is another icon, on its line, with the 1 to 4 bars of reception and a small letter, which should be looked at.
This small letter, it is “H " ==> connected in 3G+, “3G” ==> connected in 3G, “E” ==> connected in Edge
and finally a simple antenna, which I imagine wants to say that one is just connected in 2G, no data connection
Is what all that is correct?
Is there another mean of knowing in real-time the current mode of connexion (and thus mode of conso of the accumulator)?
Point B, use of Phonealarm:
like said in introduction, I force the 2G (mode GSM/GPRS) during the night, and to 6:00 of the morning, I pass it in mode “house” where I put “Car”, by also putting the pin number at it, because it seems that for this transition, one needs the pin number (is it the radio cycle on-off?)
There, the first thing, they is that every morning, when I unlock it I find myself with the screen for input of the pin number, where it is enough to make cancel (because the code already entered via PA and even already connected). Moreover, if one tries to enter a pin number, then he refuses the input.
on the other hand, at this time, the telephone seems to remain in Edge icon “E”, and does not pass in H. On the other hand, so there I reset, then he will connect to H with the boot
Have you also this history of pin number?
For hangs, it is as if WMlonglife did not take the hand to force a 3G mode or 3G+….
this brings me to the point C
Point C: WMbandswitch… after a software reset, my Tel. is connected automatically towards the 3G network (or 3G+) of orange. On the other hand the morning (after to automatic wake up through PA), it remains in E. When I test action manually a passage in 3G with WMbandswitch, it does not change anything. I tested with radio operator chip on Samsung, or Qualcomm (WCDMA). similar behavior….
To check out, I then loaded and installed Bandswitch 2.8, and tried to change into 3G, and there I see appearing the letter H. so, there is a difference with WMlonglife, which would seem to show that WMlonglife does not manage to make the switch towards 3G.
Which radio chip put in WMlonglife?
Have you to it even thing?
Poind D: use of bandswitch 2.8 (on xda): I tested. Hard to know if that is interfaced well with all the remainder. Of your experiment, which one would you advise? It does not have the system of “whitelist” like WMlonglife…
Here is, in synthesis, to summarise my questions
- Has: major significance of the icons
- B: phonealarm and switch of the 3G mode (after a forcing in 2G the night)
- C: WMbandswitch, and configuration/use for HD2
- D: alternative to WMlonglife?
For info, with normal use of browsing, email and phone, I drop of about 50% battery for 24h, that is not so bad, but I 'd like to make sure about the Bandswitch thing...
Thank you in advance for all…

Did anyone try to compare battery life between no data connection and idle data connection?
I always turn data connection off after update, but I am asking how does idle data connection effects battery?
I know it drains it...but how much?
And the reason I don't know results from myself...
Sometimes my battery drops from 100 to 90 or less over the night, sometimes from 100 to 80 or even more, with the same usage or any usage at all...so I don't know how to compare it because it's so random...and this is without data connections, it is only device with phone on in sleep mode...
I once compared an over night-drain where no connection took 3% of the battery and with data connection 4%. Approx 8h sleep
It's hard for me to compare during normal use since my usage varies a lot from day to day. So I have nothing to contribute during daytime usage.

I was using wmlonglife for some time, however one time it stops to work - i have found that i had a permament data connection in idle, but didn't notice a thing, so technically it do not drains the phone dramatically
when you guys say "idle" data connection, is the phone not automatically checking for email accounts etc? If not have you disabled them overnight - how do you do that please?
From yesterday until today, until now, I left idle data connection and it dropped in 12h from 80 to 75.
When I tried to close connection and left it overnight it dropped from 100 to 93.
By my expirience there is difference in battery drain: 15% with idle data connectino and 7% without data connection.
But numbers change from day to day...but more or less is 2x more when i have data connection on idle
might have to do with the network.. most networks do their work at night because they seem to asume everybody is asleep.. it could be offline every now and then but keeps searching for updates..
Mine has 3g toggle turned off, but the 'data connection' toggle is always on, i have three email accounts that get checked over edge every 2 hours, and battery drops roughly 2% during 7 hours sleep.
yuo have 3g off permanently or just overnight?
What do you "lose" when using 2g vs 3g?
My options about 3g mode is set to auto, so I guess it switch to 3g or hsdpa when available...

yea 3g permanently off. I live right on the edge of my local 3g coverage, and with it on itchews through the battery as it switches on/off/on/off. I get full reception using edge which is easily fast enough for surfing low bandwidth sites(like xda dev! ) twitter and emails etc.
my HD2 drains battery VERY fast when i have idle connections. when i don't turn them off my phone battery is from 100% to empty in about 6 hours.. but maybe there is a problem with my device / rom.
i hate to use your thread for topic for this but maybe anyone can help me with my battery being empty so fast? i am using Dutch stock rom v1.66 with standard radio rom. i am going to try a newer radio rom tonight. but i dont think that is going to help mutch.. i dont mind flashing to a custom rom but i want the same user interface as i now have. i dont like the custom one's with their shiny buttons and stuff..
would really apreciate help / advise!

Thanks. I think the most bandwidth site I would currently access is Facebook.
I will try 2G then. When I get more into using the phone as an internet device I guess I could turn it on.
Mind you in the middle of a major city and moving from Voda "excellent" to "very good" signal zones it should stay 3G most of the time not switch so often......
the rom i.m using makes it easy to manage data, left soft button on home screen brings up comm manager and all the toggles have been activated, takes moments to switch on/off 3g and wifi, the rest of the time the edge data just works fine.
incidentally, in terms of power use other things to look at that might get overlooked, block size on sd card, if its real small and you have lots of sd card access, such as progs installed there, browser cache there, can significantly increase the number of read writes to the card in any given time period, costing power.
I am really new to android devices.
I got a Rogers moto flipout MB511 (Canada) from my friend recently. The standby time is terribly short. Discharged within 10 hours just standby in an area with good signal strength (-69db, 2G only).
I have disabled background sync, wifi, 3G, used setcpu to use 125/125mhz when screen off, removed facebook account. (I do have gmail account setup) The standby could be even shorter if I don't do things mentioned above.
Tried different roms, like 0.18.4 (This is en.CN rom), U3_01.14.2 (This is a rom without Motoblur, is really fast!), no noticeable improvement. With Powertutor, I haven't found any suspect app consuming too much battery power.
I was expecting at least 2-3 days with phone standby in 2G.
Does anyone have the same issue with me. i am wondering if this is hardware related issue or software issue. I suspect this phone might have current leaking issue. Is there any software can accurately report current?
Any suggestions?
That also arrives at me that do I have to make?
the same trouble to me
I'm guessing it's just a standard effect of how the phone draws power. The guy i bought mine from on eBay included an extra battery with it, for that reason.
But this is definitely abnormal.
Using *#*#4636#*#*, I found the there is some problem with Android system, which holds partial wake lock most of the time. So the phone is not in sleeping state for most of the time.
I don't have data to prove this. I know some of the guys' flipout can last 2-3 days, and they all have data plan (not just something like unlimited browsing, with only 80 port available.). For some of the reasons, I feel this is caused by Moto blur. A lot of blur stuff is put into android system. They might try to communicate with the blur server, which requires SSL and 80 port available. Because my phone doesn't have data plan, communication will fail. During retry, the blur keeps partial wake lock and prevent phone from sleeping.
I got this issue with all firmwares that runs on my phone, including the deblur version. I think even the deblur version has a lot of blur stuff and try to pass back some user data back to moto server based on IMEI.
Try buying a new oem stock battery?
I am pretty sure it is not the fault of the battery. I have 2 stock batteries, standby time is proportional to their capacity.
The issue is obviously the partial lock.
Same here
Battery goes pretty fast even when not using the phone, even worse when using it.
Yeah I'm also experiencing same problems! I'm using the deblur version.
Battery drains like hell! I'm also on 2G, no wifi, no gps, no data sync!
I've checked my battery usage and this is what I got:
Voice calls: 32%
Cell standby: 22%
Phone idle: 18%
Android OS: 16%
Android System: 4%
ZDbox: 3%
Display: 2%
Cell standby, Phone idle and Android OS seem to be quite high. Anyone know why?
Thanks
Hi,
Same sh*t here...
I have better results if I am running the JuiceDefender (extreme profile: data on demand) and SetCPU (profile: on screen off: 125/125) . Note that on the SetCPU the profile options (on the top of the profiles) MUST be checked in order to be active... Unfortunatelly I am stuck to 3G only (feckin three-mobile-UK does not allow to fallback to 2G)
Also, I am running the "Quick Settings" in order to cut off quickly the GPS/data/wifi.
BTW, be sure that the Settings -> Data Manager -> Data Delivery -> Blur Applications is set to "Sync over Wi-Fi Only"
My results so far are :
mobile left the overnight charger arounf 7:30, then after 12hrs (19:00) the battery is around 60% .. all this time just some sms (no calls at all) plus around 10min email check..
cheers

three uk are a 3g only network they have no 2g system
all of their handsets have been 3g from the start because of video calling
I´ve got 24h+ Standby time, Deblur + Juice defender + Never make/recive calls with this ****.
i had the same problem. only 6/7 hours tops with juice defender on!
i switched of 3g and now it does 20 percent a day!
must be a firmware issue.
i got deblurred rom, euro.
with rom deblur,setcpu with screenoff freq 125-250 (screenon 125-550mhz),juicedefender free (set screenoff no data,app update freq 30min),10 sms received,15 mins of call,internet navigation about 10min,my flipout is now at 50% of battery (the phone is on by 9.00AM)...
but with this setting and with a more intensive use (20-30 mins of call,10-15 sms,30-40 mins of internet) my flipout goes at 0% in about 12h
Hi,
Its almost 2 months after my last reply here..
My flipout now can stay 48h on standby, and on normal usage (around 50 sms send/receive and 30min of 3g data..) can be stay alive for 1.5 days ..
The applications that I find very usefull are:
SetCPU (I set the phone to be 125Mhz min/max when the Screen is OFF)
DataSwitch ( to kill any data connection)
Autorun manager (to avoid running some apps like Skype)
I also re-calibrated the battery a couple of times (I left it to be completely drained then recharged to 100% and used a util called Battery calibration)
Not bad anyway...
cheers
