This thread refers to cases where the HTC Kaiser (and probably other HTC phone models with the same built-in GPS chip, such as Polaris) sucks the battery empty within a single day, particularly during standby, particularly if all features of the phone are DISABLED, or after low usage. Another symptom may be a phone which unexpectedly did not come back to life, but operated normally after recharging. Yet another symptom is unusually short battery life through normal use. Note, this thread is not about limited battery endurance due to heavy usage.
*** Battery drain FAQ ***
How can I see whether my Kaiser is affected?
- A large percentage of HTC phones with Qualcomm chipset and internal GPS seems to suffer from the bug described here, some appear to be robust enough, likely depending on chip revisions. If you never ever use GPS, you are probably out of risk. If you use GPS at least occasionally, you should have a look at your phone, and closely. It is possible that an otherwise normal to heavy use of the phone conceals a basic, added current consumption which is what we are talking about here. In such a situation you may have got used to a certain battery endurance, which may be much higher under normal circumstances. So far I observed currents between 28 and 78 mA, depending on DUT and OS. Some users reported currents in excess of 100mA. Note, this added current does nothing for you, except accelerate your battery drain!
How to check this?
- Check the true standby current (see the following description). That simple.
How to measure the standby current?
- Clean up: switch all phone features off (GPS, Phone, Bluetooth, Media Player, really everything). Terminate all applications, use Task Manager to verify this. Make sure no processor intensive background tasks are running (standard installations should meet this requirement). Do NOT soft reset at this point!
- Put the phone in standby, and wait approx. 10 seconds. The phone needs a while to complete entering the standby though it appears to be off immediately.
- Now measure the current. Best and fastest way of doing it would be to have a current meter connected between your battery and your phone which gives you realtime readouts. Second to that is a suitable battery tool, such as "BatteryStatus", but you have to get used to the delayed current display (see post #4 for details). Using the software battery gauge, you should wait an additional 20 seconds or so to allow for the current capture, then reactivate from standby and take the lowest possible current readout.
- If the phone is in a good condition, the standby current must be in the range 1..3 mA, roughly. If you see a repeatable current well in excess of 20mA, your phone is in the BAD condition !!
- Another simple method is to leave the cleaned up phone in standby overnight. Next morning, soft reset your phone because the phone may have lost track of the battery capacity. Check whether the capacity dropped dramatically. And also check whether the phone feels warm to the touch.
How to reproduce the problem?
- Activate GPS until you get a fix. Probably receiving the first NMEA strings is good enough, but I have not verified this. GPSTest, HTC's GPS Tool or any navigation software does the job.
- Deactivate GPS. Just to be safe, terminate the GPS software, too.
- Check the standby current.
- The fault does not pop up always, so you may have to repeat these steps several times until it appears. The phones I tested usually catch fever after only one or two tries, but it is possible that you need to cycle through this procedure 5 or 10 times. Which is in the nature of intermittent bugs.
How to reset this nasty condition?
- Fault recovery is possible by continued on/off cycling of the GPS unit, similar to what provoked this fault.
- Activating the cellphone unit does also seem to cause the phone to return to a low consumption, but maybe not in all cases.
- Try to soft reset your phone, or to cycle the power to the phone (long press of the power button).
- If you really cannot get rid of the problem, back up your phone data, then execute a hard reset. BEFORE restoring the phone, load a battery gauge software and see whether the consumption is gone. If yes, some application is likely to cause your headaches.
After performing one of the above steps you may repeat the described current measurement, to confirm that the standby current is back in the normal range.

Original text:
I have reason to believe that all Kaiser models are prone to the "excessive standby current consumption" problem. I tried it on two original "VPA compact V" by Vodafone (= HTC Kaiser), using the original WM6, ROM 1.56.162.5, Radio 1.27.12.11. I gave a **** on warranty now, stepped up through HardSPL to "Duttys_Official_WM6.1_Rom_5.2.19716_UC.zip", Radio 1.64.08.21. The results are all the same: an excessive current consumption which can vary between 25 and 75 mA. Interestingly, the current is always the same in a specific setup, but varies between phones and operating systems. In the latest case, the same phone took 28mA under WM6, went up to 78mA under WM61. Consequence being, the battery will be sucked empty within a day or so, without obvious reason. The only mitigation is a reset, or a complete switch-off.
There is no application which could cause the current consumption, at least none I installed. It does not even matter which GPS application you used. The only active processes are (according to TaskManager, latest WM6.1 version, ".exe" omitted for the sake of ease): filesys, device, biotouch, gwes, shell32, cprog, services, quickdial, connmgr, mediahubmini, taskmgr, htcactionscreen, sapsettings, aplauncher, quickmenu, nk. I repeat: ALL applications properly terminated, ALL internal units are OFF (WLAN, Bluetooth, Phone, GPRS, GPS, Camera, Media Player etc. - really NOTHING).
Before anybody prematurely states that these findings can not be reproduced: the problem is unlikely to appear if you switch on the GPS for a couple of NMEA strings, then off again (though it did already). If need be, you have to leave it on for a while, play a bit, walk around a bit and so on. Take your time testing it _thoroughly_, really. I cannot tell when the fault actually appears, and it may not come up immediately because it seems somewhat sporadic in nature - but take my word, it will, I observed this issue for a long enough time. I can only repeat myself: I am sure there is something wrong with the power management in the GPS driver.
Anybody, feel free to contribute, but PLEASE avoid funny statements like "you have to shut down all programs", "WLAN can take up lots of energy" and so on. And before you express doubts just because there are not quite many people out there who come to the same conclusions, think again. Without going into details, most users are simply not in the position to come to the correct conclusions.

OK, making it sticky; depending on the feedback, I (or other mods) may unstick it in the future.
How do you measure current while in standby? When it's running, I can see current usage in the battery monitor of AE Button plus. Just after wake up from standby, it shows 16ma. A few seconds later it jumps to 385ma and then settles at 140ma.
I'm using 3.02.DKv0.0 6.1 Lite Rom from akadonny.
@ Menneisyys: thanx!
@ tdusen:
there's two ways of doing it. First, I do not know whether "AE Button plus" works in a similar way, but "BatteryStatus" (also included in Dutty's newest WM61 release) has some seconds of a delay in the current display. I assume this is because of an averaging process running in the background which collects current samples over a certain period of time, or soemthing to this effect. Anyway; you have to keep your in standby for at least 10..20 seconds, then reactivate the PDA. If it's still showing a high current, tip on the current/power display a few times, in most cases this helps getting the low standby current. You simply have to try to catch the lowest reading, right after reactivation from standby. If everything is OK, you will get a current reading of a few mA, maximum (in most cases 1..3 mA), assuming you shut every feature of your phone off.
The other way is also the verification of the "BatteryStatus" method. I built a current shunt test probe and measured the battery current directly. Attached is a screenshot taken with my digital scope, which shows typical results (see above -- moved to post #1).
In your case - just to be safe, give your PDA a soft reset, and leave everything off. Check your current reading. If it's still at 16mA as you wrote, I wouldn't bother. Later you may fire up a GPS application like GPSTest, the HTC GPSTool, Tomtom, OziExplorerCE or whatever, and play with it for a while. Running a circle or two around your house should do it. Switch GPS off again, make sure all tasks have ended (if you want to make it perfect). Repeat checking the current as described above. It is also possible that you have to redo the test one or two times until the problem appears. You will see!
BusterTyTN
Addendum to the previous post: explanation of the screenshot.
The vertical center is zero current, discharge currents are going down. To the very left you see the PDA coming out of a soft reset, then I switched it into standby (the short flat line right before the 200sec division, ~0..1mA). Directly at the 200sec division I reactivated the phone, started GPSTest, waited until GPS was all up and running, stopped GPS and terminated the program. I also checked that no other applications were running at that time. After a little while the current settled to a discharge current of approx. 48 mA (the wide track in the center; the exact level can vary between devices). It continues drawing this amount of current until the battery is empty, or until you soft reset the device. I did the latter to the right of the screenshot, which shows another boot sequence followed by a standby, which in turn returned to a very low current consumption.
Also give a try to acbTaskMan - it's a very nice meter tool, see my related articles
I don't know anything about current measurement, but my kaiser usually lasts 2-3 days of intensive use (1-2 hours calls/day + some GPRS data + bluetooth always on + GPS once a week) and it seems quite OK for such device.

That's intensive????????
How about 5-6 HOURS of calls a day
4-5 HOURS a day of HSDPA
checking emails every 15 minutes on 3 email accounts
sending emails 60-75 times a day
WI-FI 1-2 hours a day
150 SMS/Texts a day
10-20 MMS a day
and then a few misc. apps ran.
To me, my usage is not really intensive, but I do have to have a car charger and a couple of wall chargers because I can run a battery dead in about 5 hours.
i played doom for 30 minutes starting at 100% battery, and the battery was at 75% afterwards. i had to charge it for about 30+ minutes to get it back up.
On a daily basis, i will go to school, leave my phone in my pocket on standby, then by the end of school its at about 80%. i did nothing all day and it dropped 20%.
I would agree, 5-6 hours is probably the max i can get out of it.

At least two devices work nicely as far as battey power is concerned.
I still enjoy more than 10 days standby with phone switched on.

VARIO III rom 1.56.111.4
radio 1.27.12.11
When my phone is on, but not running any active apps, it consumes about 145 mA - 150 mA with nothing but my phone on and backlight lower 3rd bar.
I've read some others guys on the forum have a power consumption of about 100 mA with higher backlight settings.
indeed excessive consumption
I must confirm the OP's finding. Though I assume it is simply related to the Radio used (see comparison in another thread where est. time of usage went from 227 to +400 minutes)
When I used my stock rom with radio 1.27, I wouls still have 40-50% cap using all day Blutooth on, no 3G, still GPS enabled for 3 hours.
When I falshed to DCS 1.7 and changed radio to 1.64, power consumption doubled, draining the battery at incredible speed (full chare morning, less than 10% in late afternoon)
I had to disable BT radio and set backlight low to let me go through the end of the day.
Looking forward to read a solution here.
With stock orange radio and rom, my device would last circa 36 hrs with very light usage and about 6/7 hours with heavy usage.
With Dutty V3 and orange stock radio (1.27) I got very similar, maybe slightly faster drain.
I have today flashed dutty 6.1 and a 1.64 radio and will monitor battery usage tomorrow.
There's a lot of anecdotal information here...
To get this to baseline information I suggest the following starting point:
1. Device (Kaiser, tilt, etc)
2. Which battery are you using (brand, mAh rating, etc)
3. Which Rom and radio version
4. What application are you using to measure current draw? (Great spot for a recommendation or a .CAB file)
5. Provide typical usage description and corresponding battery life
6. At what point do you charge the battery (i.e. top off every night, charge whenever power's available, recharge only when battery hits low level (i.e. 10%)
To effectively analyze the data, there needs to be a consistent method of capture.
Be careful not to mix up the problems here!!!
1. I assume you will not be confronted with this problem when you never use GPS at all, though you should not treat this as a final statement - has to be investigated further. So far I have not found any increased standby consumption if I did not touch GPS (well, at least after the last soft reset).
2. I am not talking about short battery uptime under heavy use, either. For instance, if you have GPS permanently on, you can suck the battery empty within 4~5 hours, max.. However, it is well possible that a suspiciously short uptime is somewhat concealed by an overall heavy use of the phone. To figure this out, you simply have to check the standby current consumption of a suspicious phone, with all its features (temporarily) disabled, as described earlier.
3. Note, this problem is all about current consumption during standby !
@ Liquidsilver:
"anecdotal information", sure. Please read again, particularly the start of the thread which will answer most of your questions. Add the thread "TyTN II / Kaiser issue: GPS & battery drain" for the remaining ones.
Please try to understand. You can get the phone into a condition where it sucks the battery dead empty within 24 hours give or take, during standby, all features of the phone OFF. ZERO usage. PROVEN, some 10 times, on different Kaiser's, using different OS's.
@ Stay0Puft:
if your battery capacity does not drop much overnight, you may look at an issue other than the one described here.
I would like to add my observation to high battery drain. Normally on my stock Kaiser rom that I used for about 4 months, normal overnight drain is 4% with radio in standby and BT On, WiFi Off. I use GPS with iGuidance almost daily and seldom soft reset.
I have witnessed extremely high power drain only a few times and they were always involved somehow with WiFi. If I have WiFi On and forget to turn it off and just put the phone in standby or let it auto power off, I have found the phone hot to the touch and dead or close to dead in only a couple of hours. The phone is usually locked up and non responsive at this point, needing a soft reset. I haven't found what causes this, it's been at home on my wireless LAN but with no active application, WiFi was simply on. I make it a point to keep WiFi Off when not actively needed and never have issues in many months of use.
If you haven't checked this out, I'd be curious to see what the current meter would show. At some point I'll drag out the scope and make a shunt as well, just no time these days...
AT&T Tilt...
I used to get 2-3 days with mediocre usage when i first bought it... and now i'm lucky if it lasts an entire day... I cannot trust it with my morning alarm anymore... I dont think its the ROM, because i even tried flashing AT&T Tilt rom back on and even the minor update on HTC... but still no luck... I think i need like a calibrator program...
Hello
I have new diamond 2 for three days. It's very good machine, but i've one serious problem with battery. I try to explain the strange behaviour of it:
1) Battery life is too short. I have read in this forum, that battery life is amazing. I dont have this opinion. My topaz's battery life is about 3/4 of a day (standard using)
2) battery behaviour 1 - sometimes i have battery % value another than after restart. For example i have now 50%. When i do soft reset i will have 35%. After second soft reset i will have 42%. Maybe i have problem with battery calibration or something like that. Or ROM is bad.
3) battery behaviour 2 - many times my battery freeze at specific % value (for examlple 40%). At first i though that is amazing battery life. Buuut no. After few hours still was there value 40%. So i tried soft reset and i saw only 16%. I really don't know what is this problem about.
I tried ariel battery bar, which is very simple program and i didn't have problems with it in the past (when i had kaiser). But here was the same problem. Value on Ariel battery bar freezed too. After softreset there was another value. Maybe i will try hard reset in the future....Now i am trying to format battery with process of fully charge and discharge. Maybe it helps.
Has someone the same problem like me?
Detail of my official ROM:
ROM ver: 1.39.479.1 (47382) WWE
ROM date: 04/07/09
Radio ver: 3.43.25.19
Protocol ver: 61.20t.25.10U
Many thanks for help
PS: i had hermes, 2x kaisers in my past, but this kind of problem i haven't had til now. hmmm
Can you list any applications you have installed or is it still original and out of the box with no applications apart from the standard ones?
How did you perform your initial charge ?
I always perform mine by doing a full charge - letting it drain and then back on charge
This happens for the first week - even if it goes flat in the car, I will not plug it in the car charger until I get home and can do a full charge!
Once the first week is done, I charge normally which at the moment has been every 2 days
Did you do something similar?
I have read on here someone else having issues which is potentially down to the battery so it might just be you have a duff battery
thank you for quick response
Apps:
G-alarm
Total Commander
Core Player
Dictionary
MyLight
Nothing special installed. I think at first i must do a hard reset because i must exactly know if this will be on fresh ROM.
First charge - as usually - it was the same like you.
Now i am charging and here is the same strange problem. I am charging now for 2 hour and battery is only on level 50%. So, now i am going to do soft-reset..............few second...................tadaaaa i have 100%. This is not normal. Here is something bad.
But thanks for you help.

I was going to suggest the hard reset route - this would determine if its software or not.
I will say that charging from empty takes a hell of a long time on the TD2! I'm thinking without even timing it, that it is taking around 4-5 hours to charge up ... and thats on mains!
Are you doing a soft-reset while it is plugged into the mains to charge?
Also is it doing this on usb charge (try another cable and NOT the one supplied for the charger)
Have you been using Opera. If so how have you been closing it. Did you go to menue exit or just hit the X? I ask because I found that hitting the X did not fully close it and when I went back to it it was still at the same page and not relaoding my home page.
Also did you set X to close the programs automatically or do you have to hold X to shut the program down?
It is also my 3rd day with the phone but have used internet a lot and the battery seems to be good. I also have been playing lots of games. I have done an initial Full charge and let it drain.... A full charge again let it drain... and last night it got a full charge.... My battery is Full at the moment. Today I have used it mildly for the web.... Like less than 15 min and have played games for about 10. A few calls and that's it. I can say it's doing better than my Elfin has.

Good point - Just for your reference, in the settings menu > advanced settings> System> Task Manager > Button tab
You can set the X to close rather than minimise - I have always set this to be the case so that when I close a program, it does close!
i tried 3 different chargers. Nothing.
Now i am doing hard-reset. Soon i will report.
report-after hardreseting my topaz seems to be fine. Before hardresseting i fully charged my battery. now i am testing it...
hmmm. really interesting. after few hours of testing everything was ok. So i decided to test it with battery applications (ariel battery bar and another tools wich shows battery bar in %.) And here started ainigain the same problems. Can someone test ariel battery bar and test some soft reset? Please watch what happend after restarts with battery %. I tried 10x restart
and everytime was there another value of battery. Sometimes higher, sometimes lower values.....really annoying
Now i have uninstalled all battery tools and i am going to test again if everything is goog...
alkapone please inform us about the results because i kinda have the same problem here, and i am using batti.
i have a lot of applications installed (nothing to do with the battery meter), but i have GPRS not 3G signal, i am closing the programs normally, and i am exiting opera, and so on. i am using it a lot but i think it goes out kinda fast. i almost get 1 day by using it.
can anyone suggest a battery meter that actually works fine? i like batti
Same problems here! Looking at the battery-information tab: After 4 hours of use after full charged the battery is empty..
I have been using dciBattery and qwertyMemory and all seems to be ok.
I have copied the files to the storage card then run the files and set a shortcut in the windows startup folder.
Here is a link to the files
http://freewareppc.com/utilities/qwertymemoryanddcibattery.shtml
this program doesn't have any config ? i don't want to have the memory bar and i don't want to have that gradient thing.
i think i solve the problem - not sure for 100%
hello to all
i think i solved the trouble. when i have uninstalled every battery app, everything seems to be ok. and one statistic - i had today at 12:00(lunch) 20% of battery. after 8 hours standard using of the phone(few calls,sms,internet), my battery told me that it has 10%. i think it is veeeery gooood (8 hours=only 10% decrease of the battery).beautiful.
result - this case showed that some battery apps/tools causes problens with compatibility battery meter vs. these apps..,
list of apps which causes problems (my tests)
1) jimmyes greens battery fixes
2) ariel batrery bar
3) batti
this is not 100% solution. i am still testing.
please write your opinion.
i am going to try finix

Hi,
I know there's a lot of talking around about power consumption and it is not my intention to open another thread about it: just an information to share.. Even if Diamond2 will not be remembered as a world champion in powersaving (I can remeber only Artemis being one), I am experiencing an additional bug that could make think that the battery life is shorter than real! When fully charged, battery level goes down quite quickly(talking about hours) but at 3% the device is able to run for at least another 40 minutes of hard work (wifi+fullscreen youtube). This may be caused by a wrong battery calibration, I let it discharge completely but seems not to work. This "hidden" extra charge is certainly a positive thing but it is disappointing to notice that HTC newer devices can have a such banal problem. It's the third htc phone I buy,never experienced it before, and its not now I'm gonna start behaving like a maniac always concentrated on how i charge my phone just to workaround their bugs.
EDIT: Sometimes after 3 consecutive softresets I get 3 different battery levels, not bad eh? I could play the lottery with those numbers
I spent most of the day yesterday outside skating. Had GMaps running the whole time with GPS and HSDP connection at all times, + a twitter client which refreshes every.. 5 minutes or so.. Also halfway through enabled G-Watch with Geocaching..
Every 10 mins or so was checking the screen (yeah, cheap alternative for a GPS Navigator ). Some photos and videos were also made on the way
By the end of the day, the phone started complaining about the battery (20% ?) and I turned off GMaps, G-Watch and the twitter client. Some 15 minutes later I got the very low batt notification (10%, right?) and I forced the data connection off (forgot about it the first time ^^ )
Now.. After that I still had to connect to GMaps + Data + GPS to check the route back home ^^
After about 1 hour maybe, I reached home.. and it was still alive.. I was pretty impressed with the battery life, but now that you say it, it is weird that it lives for SO long at low batt levels.. I'd love to find a solution. For now I'll try to do a couple of full discharges to try and calibrate it =/
Very glad to hear that Diamond2 is capable of such battery performances! (not mine at the moment). Anyway,if I'm not wrong, you confirm a strange battery indicator behaviour..we'll see

Seems to be better to put it on Google form?
Both easier to input and sort out and draw a chart.
What is the objective of the survey? Are you trying to perform data mining on the survey result to derive which pattern is more battery friendly or badly?
I think the battery usage statistics should be included as well? (both the % and time)

What is the objective of the survey? Are you trying to perform data mining on the survey result to derive which pattern is more battery friendly or badly?
I think the battery usage statistics should be included as well? (both the % and time)

You're right on that. I'll try to make a survey with stats at the end. And yes, i'm data mining or struggling to find the cause or more of them, to see, which part of the phone is also the reason of huge battery problem we're having. Its not that we have a million more choices... some also reported bad battery life on 2.1 but i'm not sure this is software related then.. give me a day or so to make it happen then

Quoting again- just created form. Please help out if you can
Form submitted..
good call on setting this up.
form submitted.
you should probably add the question "battery percentage remaining?" after the time since unplugged bit so that we have a more accurate idea of how much use people are actually getting from one full charge.

I want to say something about battery draining of my milestone.
I recharge it until morning then go to work.At 12AM the battery is at 15%.Hmmm.. so i did some research..i updated to Cronos 1.5 ROM and then i did something unuasual.
I rebooted the phone when the battery was at 15% level. When it restarted the battery had 80% power and it lasted till night. Do you have any explanation?

Hm, maybe there's something about it we have in common.
I usually went to bed with 80% of battery. When I wake up, its at 30%. Now, if I start charging it, the battery charging indicator shows as if it would charge it from 80% to 100%.

thank you! This dodged me till now. Had the same experience with battery as some of the guys here.
Okey done!
Hi all,
Form was submitted 22 times until now. There are some amazing stats included with some, that suffered the same problem as I did.
okorn is the winner at the moment, with 15% to go, his phone lasting 40+ hours on Telus Lite (Eclair!), where the longest on Froyo would be more than that (petyo.tsanov) running Cyanogen Mod for 20hours and still having 60% of his battery.
Its too early for any conclusions, but,.. just for info, most of us/you who filled the form did have some kind of sleep policy on (data/2g-3g-wifi).
I'll try to show you all results by the end of the week with all info
ps: Its still not too late to submit your info about Battery drainage at http://bit.ly/motodrain
Thank you!
Form sent.. have a good work!!
=)
GPS test
hiya ! ..
i did a GPS test on a hike last saturday ... with offline maps and oruxmaps set to
record position every 2 minutes ... phone was in flight mode, killed all apps on
startup.
at the end of my hike (approx 10.5 hours), the battery was at 60% and 3818 mV
with time since boot - 10 hours 49 minutes.
this was on stock 2.1-update1 ... i'll be doing a similar hike this weekend ... will
use the G.O.T leak + cyanogen mod beta 0.04-10.11.20 ... shall post results
once done !
cheers !

perfect test! do post results!
Hi all. I just finished with my project about battery draining. I've made an article about it, including results.
Check it at- http://bit.ly/milestonebattery (google doc, no sign in required)
Speechless.. you did an optimum work!!!
Hoping it will improve my MIlestone life!!!
Another thing I tried today: I tried to FULLY discharge the battery, and then charging again.
Turned on in the morning from a full charge, my MS fastly went to 50% for lunch time, after middle usage. Then, at 30% this afternoon, I decided to discharge it viewing YouTube with maximum luminosity on display.
After few minutes, 20%, then 15%, 10 and 5. In short words, it decreased from 30 to 5 in 12 minutes.
And then, the surprise: the Stone played YouTube video in WiFi streaming for over 40 minutes, staying at 5% and red led blinking continuosly! So I ask, maybe a big problem of Milestone battery life is just an incorrect reading of the battery level?
Can you try, just to see if it is my only case, or it is a common case?
and thanks again for your work!!!
I bought my galaxy S two months ago. Its a great phone but the biggest problem for me is battery. When i go to sleep (7-8 hours) and my phone is idle, my battery drains like 10-20 % every night, even when i switched off fb updates, no wifi, no gps, dont have a live wallpaper, and my brightness level is the lowest. I dont knwo what rooting is or rom is. i m a fresh noob, and i need some advice to get increase my battery life. Please help me!!! what should i do?
please help anyone?

but doesnt overcharging the battery damage the battery even more?
How I solved my battery drain problem!
Have you tried turning off 3G?
I also had this issue battery drain was huge. It started appearing suddenly one day. Its a very slow process to figure out the culprit. I did a step by step analysis.
1. Found out that battery drain was happening only when 3G was on. Verified this by switching off data network (long press power button to deactivate).
2. Also verified abnormal data usage in my carrier page when I was not using my phone [like - 3G was on and I was watching a movie at a theater].
3. I also saw abnormal battery drain soon after I started Google Maps after a fresh reboot.
4. So I identified the culprit - Google Maps - but was not sure how to solve battery drain [Google Maps restarts, if you kill it].
5. I installed a variety of apps to identify the battery hog. Finally I went for Task Identifier.
6. Task Identifier finally showed me what programs started while my screen was off, etc. And I started noting them. Finally I figured out that Google Maps::BackgroundFriendService was running frequently.
7. A quick search on Google helped me understand that this is about Google Latitude. It searches for your friend's location every now and then - leading to battery drain!!!
8. I opened up Latitude and signed out from it [I guess the sign out option is in Menu -> Privacy].
9. Do not re-open Google Latitude after this - you will get signed in again leading to battery drain.
10. After 2-3 months of search and prodding, I finally figured out the cause of battery drain and fixed it - now I get 2 - 3 days of charge in my battery under normal usage!!
I'm happy now!!
Hi,
If you're using Froyo and can access file in your phone,
In task manager , on the tab "Summary", click on the "start monitoring" button. Let it monitor the phone over the night. The next morning, there should be 2 files created in your sdcard, one is CPUxxxxx and the other one is battxxxxxx.
The Batxxx tells you when the percentage of the battery at certain time of time. the CPUxxxx will tell you wht applications are running during that period.
When i used it first time, i notice that facebook and lattitude always running - when I stop these 2 tasks; i get a normal drain again.
while you guys are at it.
here's my "problem".
when I surf for an hour over 2g I losing about 10% batterylife and android reports that my display uses around 90% to 95% of the battery.
display is set to lowest brightness + screen filter.
is that normal? (im guessing it is not).
used dozens of different roms (stock, darky, jims, etc...), same behaviour everywhere.
i already did all the battery stat wiping and whatnot.
is it a faulty battery or display or something?
for the OP, maybe a combination of the above with this could help :

Sounds normal to me. 10% loss while surfing and 95% display is nothing extraordinary.

i have the same problem too after upgrading to Froyo 2.2.....what i do was turning the data connection off yand you will get 2 days with moderate usage....but oneday i had overcharged my phone (about 8 hours i think) and after that my phone can stay about a day and half with moderate use......btw i already did the 8 hours charge during my first charge long time ago.!...hope this helping
