Battery being drained (heating up while in standby) - P3600 General

Hi All,
Wondering if any of you have this problem with your trinity. I usually power off the screen and keep in the pouch. It tends to heat up alot on plastic and the battery drains extremely fast as if the screen is on.
But in reality i haven't switched anything on (GPS/Data Connection/Wifi/Bluetooth).
Anyone know whats going on?
By the way my ROM is 1.23.707.6, Radio 1.35.00.11, TRIN100.

Are you sure you haven't turned on a GPS app by mistake- GPSInfo etc?
Can you check Settings/Memory/Running programs and see if anything is listed when the battery drain occurs. GPSInfo doesn't close by itself so if running, it will keep the GPS awake, and drain the battery. Have you tried putting it into 'Flight Mode' to see if that fixes it?
When you power off the screen, are you using the power switch ( top right side?)
Are you in a marginal 3G region? If so, the device will constantly search for a 3G signal and switch from GPRS to 3G many times. 3G drains the battery quckly anyway, but the constant signal searching drains it quicker. To test that, go to Phone/Settings/Band and switch the upper box from Auto to GSM.

Hi NeilM,
Thanks for your reply. Yes I am using the power switch and there are no programs in the memory. I just switched teh Band according to your recommendation but I set it to WMCDA instead. Seems to get me stuck on "3G" while with GSM I can only get "E" - Edge/GPRS. Also I set the GSM/UMTS band to UMTS (2100+800).
I am charging it now so I will check it out tomorrow to see if it makes a difference.
Thanks.

WMCDA is 3G only, so setting to that will result in no signal if you are out of 3G coverage. Setting to GSM will mean you can't connect to 3G, but will still continue to get G or E, which consume much less power.
The GSM/UMTS band can be left to Auto.
If you find that the 3G switching is part of the problem, using a small program called Bandswitch will allow easy switching between the services; better still, it's free!

You may want to open up your case and check your battery. There may be a short on the connectors somewhere which is causing a massive drain. Tell tale signs will be burn marks on the battery.

I've checked the battery seems to be fine. But I decided I will send it in for warranty and got a replacement. Just charging the new one. Will see if it helps tomorrow.

By the way I looked in the WM6 threads and found this:-
http://forum.xda-developers.com/showthread.php?p=1263211&highlight=battery+drains#post1263211

I have the same problem occasonaly. Think its the band issue because I had it in a concert where my signal strength was not good

yeap i can verify that now. My battery power is normal now. The tool Comm Mgr Pro is also useful to switch between 3G and 2G when I require it. I get Edge when I am 2G. While this helps, but probably won't be able to receive 3G video calls when I am on Edge.
Also I don't know why this never happen to my Hermes (O2 Trion which I bricked). One difference i noticed my the hermes is that the band only changes from G>U, Didn't have the switching from G>E>3G>H. Maybe its the new software i saw mentioned a couple of times in the forum.

Terrible battery life

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.

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…

Speed up ALL DATA CONNECTIONS

Alot of us live in places where we have access to 3g and HSDPA, but T-mobile makes all of our phones choose the data speed connection that is strongest, NOT fastest. We need to find out a way to change the to choose fastest speed instead of strongest connection... if you go to settings -> comm manager -> 3g, click on it, you should see the network type on AUTO, but change it to WCDMA. GSM is edge connection and WCDMA is HSDPA & 3G i believe.
http://www.wisegeek.com/what-is-the-difference-between-gsm-and-cdma.htm
THIS IS WORKING! I just tested it, and instead of having 4 bars of edge (maximum) all the time, i had 3 bars of HSDPA for about 4 hours, and later today it changed to 4 bars of 3G most for the rest of my day!

Nothing new here but good post!! However, how is you battery life doing because when your phone is in an area of low signal it boosts the transmit power to compensate which is valuable juice being wasted.

I think the real question here is what uses more juice, searching all the time, or sticking with what you have.

That entirely depends on the situation, as several factors come into play. Not to forget, how much does it mean for you that you have faster data ?
As a result of all variables, an answer can't really be given. Users must test for themselves in the areas they frequent what works best for them, taking into account those factors they feel are more important.
Unfortunately as far as I know there is nothing on the HD2 like one of the hidden engineering menus on the GSM OmniaII, where can you actually tune the conditions for when to take 2G instead of 3G if both are available.

20% ummm takes me around a full 24 hours to get down to 20% when I don't have it locked to 3g
Who cares how long it takes to get to 20 percent battery .
It is not like you are in an island with no power source to charge the phone.
I charge it at night while it is connected to computer USB.
Then I go to work the next morning and I can plug it to the car charger.
Or when I get to the office, I can connect it back up to the work computer to juice back up.
Then on my way home in the late PM I can connect to car charger again.
Until I get back home for the night, where I can hook it up to home computer once more.
And the loop happens all over again the next day.
So why worry about battery life, .
We live in the city jungle, lol.

Well, I decided to start testing it here... I get HORRIBLE coverage at my house... I'll bounce between edge, 3G, and HSDPA randomly depending on where I am in the house.

First of all, i really recommend you flash your rom to NRG, since you just got your phone (energy rom makes your phone 9081290847% faster and better) for real. Plus you don't get all those errors from winmo.

[Q] Crazy high cell standby killing my battery life?

Help!
I'm running the 81xx firmware on a direct-from-dell unlocked Streak.
My battery life has so far been abysmal, and looking at the battery usage screen, my cell standby is usually over 60% while idle is less than 20%, everything else like 2%. This isn't from weak signal, though; I am in a well-covered 3g-only area and my phone has reported only being disconnected about 4% of the time.
Another strange thing is, my data indicator is constantly switching between the H symbol and the 3g symbol.
Anybody know what's going on?
It might be that while you are well covered for 3g, you are marginal for HSDPA and that constant switching back and forth is using your battery. I have not tried it but have a look and see if you can disable HSDPA in settings somewhere and see if that helps.
i'm usually around 40% cell standby.. do u have any task killer apps installed? although people think those are useful they usually do more harm then good.
I have the same problem, and I used another Android phone in the same location (hence same cell coverage) with no such problems. I just took my phone off the charger and had the display on since then non-stop. Cell standby used as much battery as the display!! There's no way that is appropriate.
I'm running build 8102, but it was the same with 6941 before. Can't tell about 1.6 as I bought my streak used with 6941 on it.
What Android version are you guys running? Maybe we can find common denominators.. :/
Edit: here's a screen shot of the battery usage after a while off the charger with the screen on constantly:
http://i.imgur.com/3OrqZ.png
You must be Australian W0nk0
Do you think your antenna might be loose or defective?
I can't imagine the antenna to be loose really - but who knows, I bought mine used. If so, I think there is a signal strength value in " about phone" somewhere, no?
What signal strength are others getting? I'll post mine later, I'm on airplane mode right now so that I get some battery life.. :/
For signal strength, I am getting -75 to -95, and 9 to 12 for the two values while riding the train (not subway).
It also appears my battery life is quite good when my phone is in standby and not doing anything... the problem seems to come from net browsing or anything else that uses an active connection... Just browsng XDA is taking about 2% a minute!
Oh and my android is the 81xx 2.1 version with the modaco tweaks
Sent from my Dell Streak using XDA App
I had really high cell stand-by too. then i installed juicedefender, now my cell standby is down to about 29%.
I think the main thing is that it disables data connections while your screen is off and only turns it back on when the screen is on and unlocked. It also has a setting where it enables data connection periodically to allow background syncs and whatnot.
I'd recommend you guys give it a go, it had almost doubled my battery life!!
Mine shows,
cell stand by 50%
phone idle 44%
it seems quite common on the streak as I read in all the forums. I am on 2.1 stock rom? what's 1.6 like?

Battey drain due to radio?

Hey, I am trying to figure out why my battery drain is so high. Part of it is the display (trying to work on that too) but I see that my "phone signal" is quite bad. I have a feeling that this is draining my battery.
I have attached my battery stats. Do they look normal. And does the phone signal look normal or below normal. I think it is worth noting that I almost always have 4 bars of signal so I am not sure whats going on. I use my phone in Canada on the fido/rogers network (i believe it is the same as At&t in the states). Is there another radio I can flash or something if this is not normal (which will still work with my phone/network)?
Thanks a lot
Reports are that using 3G a lot drains the battery immensly.
Try switching to use 2G only and see how that affects your battery life.

I dont think it is worth it to pay $30 a month to use 2g networks. I will try to turn off the 3g radio when on wifi though. And maybe only turn on 3g when i need it. As for the phone signal bar. Is it the same or worse than what you guys are getting?

It already works this way. Wifi is going to be your best bet to lessen drain if available (both in standby and when using data - just make sure you have the sleep policy set to never).
If you have poor signal you are going to murder your battery - no way around it. The radio will boost power (Gain is adjusted automatically) in an attempt to get a better signal - and constantly search for a better one. So if you are bouncing between no service and 1 bar or even with just a weak 1 bar signal you are going to see atrocious battery life. There's not much you can do there except potentially switch to SIP in those times if you use a SIP provider.
If you are sitting with 4 bars then you should be seeing decidedly better battery life. What is the actual time the display was on in that screenshot?
I use 3G and its fine. What radio are you using?
the choices are: JK8, KB1, KB3, KD1
you can find them on the dev forums

Hey, I am trying to figure out why my battery drain is so high. Part of it is the display (trying to work on that too) but I see that my "phone signal" is quite bad. I have a feeling that this is draining my battery.
I have attached my battery stats. Do they look normal. And does the phone signal look normal or below normal. I think it is worth noting that I almost always have 4 bars of signal so I am not sure whats going on. I use my phone in Canada on the fido/rogers network (i believe it is the same as At&t in the states). Is there another radio I can flash or something if this is not normal (which will still work with my phone/network)?
Thanks a lot

that looks pretty normal for that kind of usage. id say that you were a moderately heavy to heavy user.

It already works this way. Wifi is going to be your best bet to lessen drain if available (both in standby and when using data - just make sure you have the sleep policy set to never).

I usually have about 3-4 bars. The time on for the display was probably just over 2 hours (judging from what it is now).

I have KD1, how does that stack up?
also, I am using netarchy bfs kernel if that matters.

I agree. you're a pretty heavy user So far different radio doesn't drain battery, but only the difference of data connection speed cap.

Yes I do love android (been tinkering around since the g1). I do realize that I am a heavier user than the average person but it might also be that I recently got this phone so I am using it more.
Aside from that, does everything else seem normal?
"Android System" should not be taking such a high %. It should be about 1-2%.
There is (was?) a bug that causes high cpu usage (and shows as Android System) when wifi is on, but not connected to a network.
Another thing I can think of and is something I've experienced, is that sometimes you get an IP address from the mobile network that has a lot of noise, that is, it's an address someone has likely used p2p programs with and there are lots of connection retries. You can see it because the green arrows don't stay dark for more than a couple of seconds, and it kills your battery quite fast. Reconnecting to get a different IP address is the only solution...
Also, bluetooth may be a factor...

Blutooth is always off unless I need to use it (which is rare). I am not sure how to make my mobile network connect to a different IP adresse, would turning it on and off do the trick?
Being in area where there is low/no signal also causes my battery drain to increase by a lot! Which sucks cos where i live i get either 1 or no bars of signal.

[Q] No LTE + Battery drain after tethering

I got a weird one for you guys. I had LTE on my nexus 4, but after tethering for awhile, my LED started flashing red and the phone got hot. So I turned off tethering, but my LTE became intermittent, and over the course of the next day, I lost LTE connectivity altogether, even if I set it to LTE only, I wouldn't get any signal. This is what I've tried, changing different hybrid radios, changing ROMs, factory restore to original ROM. The other symptom, and the one I care more about, is that my battery now drains pretty quickly, whereas it would last 3 hours of screen time on before this incident, now it lasts less then an hour. And it seems to drain while the phone screen is off. Anyone have any ideas what it could be? Did I burn out my LTE modem?
I think you need a new battery.

I have a feeling it has something to do with the modem. Day 2 with the damaged phone reveals that my signal will go in and out, sometimes it will be on 3g, sometimes on edge (even in 3g areas). If that's the case, a new battery won't necessarily help.
Now 3g is gone completely. I can only use 2g. Anyone else run into this problem?
I had this problem a few years back. It was the wireless provider who was adjusting my internet speeds. After one simple call they stropped doing this and my phone was always connecting at 3G (I don't have the LTE hack installed)
