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...
Hey everyone. I recently purchased a 8925, and am experiencing the battery drain issue that some others have mentioned. I used to own a 8125 and its battery life was much longer (easily 3 days of my usage). I installed batterystatus on the tilt and it seems at idle with all apps closed its pulling 60-60 mA, where my 8125 used 10-15mA. Has anyone come up with a solution for this? I currently have 3.29 hardspl with the stock wm6.1 installed.. any help is much appreciated

turn the lcd brightness down, get kaiser tweak...set your mobile internet connection to go off after a period of a minute or two of non usage (thats a big one)
I have done these above listed, brightness down all the way, i disabled the internet connections with nodata, and i did a couple things with kaisertweak (sd power management). This seems to have no effect on the drain
Less is better when it comes to longer battery life....

Maybe all the extra bits of software and utilities that have been installed are gobbling up those CPU cycles (and consequently the battery charge). I have a very basic setup on my TyTN II and reducing the screen brightness right down as well as changing to GSM (rather than 3 G) makes a huge difference in battery life. Even disabling HSDPA and resorting to just 3G makes a difference. It's time to simplify things I think and rather than installing apps to stop a data connection starting up for example, delete any data connection settings on the phone and simply don't do anything that may require a data connection.
How long are you getting out of a charge, doing what sorts of things how often? I'm sure if you hard reset back to the basic ROM and test again with just these few changes, you'll notice a big difference
If I simply flash the stock ATT rom on the phone, and install batterystatus to view my drainage, it is still at 47mA. It seems turning off all the data stuff saves maybe 10mA... i understand that a bad battery would drain faster but would that make the 47mA on standby? i thought that measured how much the phone was using? maybe the battery is bad. just yesterday i left at 7:30am with a full charge. I litterally sent maybe 4 text messeges and maybe a 3 minute phone call, the rest of the day it was on standby, and at 7:30pm it was down to about 34%! this is unacceptable!
Does anyone know what batterystatus reads? either the rate that the battery is losing power or the rate the phone is using it. is it possible that the battery is bad and would cause it to drain at a higher amperage? i know a bad battery drains faster but dont know about this.
I feel your problem. My tilt is so bad that it still drains while charged in the car. Maybe a bad battery but this is crazy.
ok I talked on the phone today more than usual (maybe an hour max!) and it shows that the battery drains super fast when making a call, which to me says the battery is just toast because a call uses more power. I was hoping to find a solution but i think I will just purchase a new battery.
how about buying a slim extended battery on ebay, the 1600mah one. You will definitely notice a difference

Well from what I hear the ATT ROMs have lots more 'stuff' than the native HTC ROMs but whether that means more CPU cycles are used when those programs aren't started I doubt. It's really background utilities that'll be of concern. Rather than installing software (which itself will use battery charge) to see why your battery charge is going down so quickly, what's wrong with going about your normal usage without non-essential utilities and keeping an old fashioned log of how long a full charge lasts and what activities for how long you used your device for? If you try some of the suggestions already given and keep a careful log, you will notice a marked improvement - I did. Whether you wan't to keep those changes though is important. I found the screen was just to difficult to see at low brightness settings when out in the sunshine so I've set it back to a high level and carry 2 spare batteries with me when I'll likely be out and about using the device for a full day - I've yet to get through all three batteries in a day and they're compact enough to easily carry around. With my cradle that has a battery recharge bay, I can also recharge all my batteries overnight.

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

Guys,I own a T Mobile G1 Android 1.6 Phone and recently I’m facing some problems. The problem that appeared recently is with the battery drain. before some days ago the battery of my G1 lasted up to 4-5 days, without using Wireless, GPS, and Bluetooth. If I used the mentioned services normally the battery lasted up to two days. But recently the battery is draining too fast. Within 4 hours the battery goes down less then 15% even I do not use any mentioned services. I keep my phone on standby, without talking a single minute with the phone, not using any service etc, and again it goes down very quick. I took some measures according to HTC instructions how to save the battery but again it does not function. I uninstalled all applications and reset the phone to factory setting by again same thing. Then I searched on the Google some instructions, I tried also that one’s but again it does not function. I always used HTC charger that came with the phone but again same problem. What is the strangest thing that after some days the battery gets back and works perfectly for two weeks, which means I use the phone normally without charging 4-5 days. As I operate very well with the smartphones, Pocket PC’s etc I start analyzing G1 and monitoring very closely why the battery goes down, I monitored for a long time the query under the :About Phone-Battery use- and I see there that Andorid OS is using the battery from 76% up to 85%. Now it came to my mind that something is keeping engaged or it keeps running the Andorid OS always on. Then I suspected that thre my be any virus on my phone, but I installed form Market Flexilis/lookout antivirus application, but there was no virus and again the battery goes very quickly down. As I said after sometime the system returns to normal and the battery lasts for 4-5 days, and when I check the information under Phone,Battery use, I see that the Andorid OS is spending only 6% of the battery. Comparing with the previous description it is a huge difference. According to my opinion there is a small problem with any file which keeps always running to much the Andorid OS. Can you please give me any instruction why Andorid OS is spending that much the battery? Or give me any instruction how to prevent this operation that keeps Android OS to much engaged? or is there any programming mistake?, is there any need for update?, do I need to root my phone as it is not rooted? The reason why I’m thinking that there is a technical problem is because sometimes the system gets back to normal and sometimes it goes out of normal running. I appreciate a lot if you could help me to resolve the mentioned problem.
I've noticed the same thing on my G1 sometimes there is fast battery drain and it seems associated with Android OS. The percentage is over 70%. I also notice it be associated with the display as well. Could be that there is some process that won't stop running and is using Android OS or it could be that on other occasions the display is not going into sleep mode properly. I wish I knew how to fix these problems but I don't. I just observe them.
The battery issue, is an up and down problem for me. Sometime I can go through it in one day or less, other days it will last me for 2 plus days.
It also could be that the battery need replacing. Who's know.
I just bought a 2nd hand G1 - works just fine. I rooted and installed CM6.1.
My battery drains within 1-2 hours. I've tried various methods of resetting stats, with no luck. How frustrating! I wonder if it's a battery hardware problem or software?

I also faced bad battery life on various roms. Since I'm using COS-DS (android 2.3.3) http://forum.xda-developers.com/showthread.php?t=950765 and the Biffmod kernel http://forum.xda-developers.com/showthread.php?t=950765 the phone runs more than 24h when texting and calling. Of course you should apply the 14MB RAM hack in comination with this kernel http://forum.xda-developers.com/showthread.php?t=831139. On standby (everything off, except data and 3g) my G1 runs >48h, before it needs to be plugged in.

Sounds like the basic description of the USB Charging Bug.
The bug triggers if the G1 is using a kernel starting 2.6.35 and onward tree, and charged using the USB instead of AC wall charger.
A couple of option to avoid the super discharge after that (you can use either);
1. Reboot after you unplug the USB charger.
2. Change kernel to one from 2.6.34 tree
You can also visit the Dev sub-forum, there's a thread there discussing the debugging process.
It is so unpredictable for me...I have just got into the habit of a reboot after unplugging USB.
Battery drain on the G1
I have the same problem. Even on standby it drops to less than half of its battery life. Sometimes its worse. today i noticed that the battery percentage was at 84. Next thing I know the phone reboots itself and it displays that it has 1% battery, battery icon empty all in red and LED flashing in red. Then I turn it off connect it to the charger, after a couple of seconds I turn it back on and says its 90 something percent. Could be a virus or just a battery bug,that's my guess. I scanned the phone with Lookout Security and there was no Virus,malware or spyware found.
I want to try different kernels for this battery issue but want to make sure I am installing the right one.
I have CM6.1 with 2.22.23.02 radio and DangerSPL installed. Can I just load any of the kernels built for EBI0?
Specifically, can I flash the kernel in the 1st post here? http://forum.xda-developers.com/showthread.php?t=1010932
Thanks.
Hello i recently bought an older xperia x1. The problem is that the battery is emty in really shor time (10 hours), so i bought a new one. But the problem is the same.
I tried Kovsky unoff rom, also official rom.
Also tried clean rom with nothing installed and no settings changed, also some power management apps for win mobile.
Everything is turned off, wifi, data connection...
abcPowermeter shows 150mA power consumption, also when display is off.
taskmanager shows only 5-10% CPU usage for gwes.exe, i think thats normal when rendering results from taskmanager and all other CPU is for idle process.
I dunno what to try to solve this problem. Any ideas ?
My guess is you are running an always active program (like an IM program) that is sucking juice.
You may want to do a clean install and run it for a couple of days. See if the problem is your hardware or if it is that some software is the cause.
My battery life has improved from about 11-12 hours to about 48 hours after removing Palringo from my startup folder.
Also you mentioned you tried a clean ROM with no installed programs. If you didn't install any and you consistently have short battery time you have a hardware issue. Do the hard-reset, flash, hard-reset to ensure a clean install. Use a good ROM and do not install any apps. If after 4 days you still have short battery life then either your battery is dying (or generic and bad quality) or you have a hardware fault.
i tried hard-reset, flash, hard-reset. No changes
150ma idle is quite high IMHO. I run a test before because someone question my roms' battery usage and it should be around 80ma idle. http://forum.xda-developers.com/showthread.php?p=4784976&highlight=battery#post4784976
1. load the same radio.
2. Install Homescreen ++
3. Follow the conditions I tested over that post and see what you got.
Make sure you are in an area with good GSM signal too. Bad signal could lead your phone use a lot more power.
BTW, I found FDC task manager may not report real CPU usage especially if problem with services.exe. Try Memmaid to read CPU usage.
That acbpowermeter is a cool app. I never realized the panel I was using used so much power, and I didn't think having wifi on would consume as much as it did. Right now I'm using the WM6.1 that came with my phone and using the SonyEricsson panel with wifi off, and I'm getting an average of 70-80mA with the display on. Is this a good number?
I was looking into flashing to a 6.5 rom. Would I be getting better or similar battery consumption than the 6.1? If not, I think I'd rather just stay on 6.1 and customize my today screen with some eye candy, etc.
@jackleung
tried your radio with your rom, power consumption is even bigger, than in stock rom
