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...

Are you on T-Mobile? Do you have a fairly strong 3g. signal ? if one did have a fairly strong 3g signal would this still be advisable?

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.

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…

Hi guys,
I just want to know, what battery life are you guys getting with push email turned on. I have to charge my phone almost twice a day with reasonable use.
10 emails
1 hour calls
4 sms
1 hour web browsing
(no wifi or gps)
I can get 3 days with push switched on if I only use 2G and don't use the phone very much.
ie. push isn't a big battery drain in itself.
Maybe push is not big battery drain but being connected to 3G or HSDPA network is BBBBBBIIIIIGGGG battery drain.
I can get through near the week (5 or 6 days) making a few phone calls and SMS with Data Off whereas with 3G on, I will barely last 2 days (and surfing in the train when going to work (2h), battery will not last a day !!). And as push mail implies data on, I would say that it has an impact !!
3G kills the battery.
You can still push email through 2g.
I wonder if someone can create a program that will automatically switch the modes on and off depending on the amount of data being transmitted?

still nothing out there to switch it to 2g when the screen is off huh?

THAT! would be an awesome feature.
Data = radio being used, display = live wallpapers and the amount of time the screen stays on plus other additions are a big battery drain but sync in itself isn't that bad even on 3G and I have a G1 with its crappy battery.
Check Settings...About Phone...Battery Use to see what is using the most power. This can help identify unexpected battery drain.
For example some people also forget about widgets that use data like the weather and news widget. To maximize battery turn off all "background data" apps that you don't really use.
Also get Advanced Task Killer and set it to auto kill apps that you don't want running long term (be sure to setup the exclude list for those you want running).
You can use the Power Control widget to enable and disable unused items like Wifi, bluetooth, GPS, and background data.
Set your screen brightness to as low comfortable. On my phone the screen uses the most battery so this is important. You can use the Power Control widget to increase brightness quickly if needed.
Use 2G to save battery. For most stuff it's really not that bad. Use Wifi when you can as uses less power than 2G and is faster than 3G.
I use my phone a lot and it lasts all day. I don't really care if it lasts longer than 16 hours or so if it does all the fun stuff I want between charges.
^Excellent tips! Welcome to XDA!
I am trying to save battery life and force my phone to have only voice/sms/mms capabilities only. I have background data disabled, roaming disabled, 2G-only enabled, and fake APN. However there is still an EDGE icon and it periodically flashes the up/down arrow. Is it trying to poll for internet or is this just basic cell tower polling for voice calls?
Also, there is a method of disabling internet permanently through the testing screen, which requires entering a code to access. Is this method more complete than a fake APN and thus better for battery life? I am afraid to test it as I don't like messing with hidden menus and want to easily be able to revert back without having to remember a code.
And yes I am aware this is a smartphone, but I need it to be a light-weight featurephone for right now.
All I can add is that when I unlock (not carrier/sim unlock) the phone I can see the Edge icon with the arrows flashing for a sec or two before the WiFi goes out of sleeping mode. My NetCounter application doesn't pick up any data drawn during that time. So either it doesn't transfer any data with the Edge during that time or the application is not perfect.
I know that doesn't answer your question but it can give you hope that the icon _may_ not be reliable.
Edge icon means its running on 2.5g mode. Shouldn't bother you much. Install 3g watchdog and android and set it up. Have look at activaty. Only way to make sure

I'm not worried about data usage since I don't have a data plan. I'm only concerned about battery life, because it seems to be polling EDGE. If 2G voice calls and 2G data polled the same time using the same line and disabling data wouldn't really make a difference for battery, that would be good. But I'm not really sure.

Best battery life check: charge your phone up to 100% before going to sleep and unplug it, wake up and look at how much battery life you have left. It should be 98%+ if you didn't use it before going to sleep. This is even if you use it as an alarm clock and the screen is on for 3-10 minutes during your alarm/snooze/wake process.
Edge is a 2G network, the best way to test your device to see if it's doing anything is to open up an internet browser and see if you can get anything. If you can't open Google's homepage, your internet connection isn't being used and your standby battery life will be through the roof. This will also, in my experience, prevent apps from launching and causing partial wake issues and keep your phone idle time longer. I forgot my phone at home one weekend, came back home and lost like 8% of battery. I'd guess you are experiencing about the same if you can't get on the internet.
My phone is i9506 and it is rooted. My problem (?) is poor battery life, I only get little over 4 hours "screen on" time. My ussage isn't very hard, most of time I only chat with my friends over 3G/4G network. I even limited CPU max frequency because i want better battery life. I use Greenify for all apps except WA and FB Messenger. Brightness is most of time lovest possible. My question is: Is that normal battery life?
Any ideas? That 4 hours screen-on -time isn't just enough for me...

Its about normal. Want more than 4hours? Use wifi instead, 3g/4g really drains the battery. Actually, if you're just chatting and dont need the speed, you can use 2G, its more than sufficient for WA unless you're sending and downloading big pictures etc. that's about all you can do really.
Thanks!
Second question: What is the fastest way to change network type (I mean between 2G and 3G/4G) witout having to go to settings?

xposed module intelli3g. It can even automate the process for you (screen off switch 2G on, open XYZ app toggle 3g/4g)

Intelli3g is just it what I was searching for!
