Battery Diagnostics

Hello,
I have upgraded my Imate PDA2k ROM Helmi_BA_WM2k5_AKU3.5_v1.4.CF2 R2 by baniaczek for about a month now. It has been working perfectly fine with no much issues on Wifi and other stuff. But since last one week i see my battery runs out within 3 hours and each time i had to re-charge the same. Even though the usage is really minimal. ( May be 2 or three calls and no real PDA usage). Also i feel the device is heated up most of the time. Are there any diagnostic tools for battery ?. .. Is this caused by any program running continously.
Any suggestions to find out the battery problem.

It is probably a running program or some activated interface (GPRS, IrDA, Bluetooth, Wi-Fi). Make sure they are all deactivated.

Thanks for the reply. I have tried disabling BT/WiFi / GPS ( even deleted GPS Connections ). Still the battery runs only for 3 to 4 hours. How can i figure out which of the applications might be causing the problem ??..... ( As i stated in my previous post things were fine two weeks back ). I can not figure out!... Can this be a hardware problem ?. Should i try flashing the ROM again ?.
Any suggestions will be of great help.
Thanks.

Is the backlight always on?

No. I think its a hardware problem. I flashed the ROM again and still the battery was draining really fast. Anyways i will change the battery now and check.
regards

Perhaps the battery is getting life expired. THe most common indication of expiring battery is that it stats taking longer to charge and gets drained faster...Try replacing the battery..

Your right but it shouldn't happen in so great leap. You said that you flashed another ROM. Try doing master reset and leave the device in factory-fresh state - do not restore anything from backup imediately. If it is fine then, it is a software problem. If it is not, try turning on the flight mode for determining if it is GSM related. I'm afraid that a new battery won't solve anything.

?
i'm guessing that your IR is turned on since you did not state it on your post earlier!
IR eats your battery like pacman does.

It would still be interesting to have battery diagnostics software. Does anyone know of such a package?

http://www.spbsoftwarehouse.com/products/benchmark/batterytests.html?en
might be useful for testing.. could potentially try different screen brightness and speeds to get a comparison. I will say that I used to only get 1 day from my old OEM battery.. got one of the e-bay special 2500mAh and now it easily gets 3 days with the same usage pattern as before..

After a long time again a re-post on this. Well my problems seems to be not getting over. I flashed the PDA2k to factory state and still the battery was draining. Then next obvious thing was to replace the battery. Now i have a brand new battery and reflashed again to factory state and my fears are coming true... still the battery drains in 3 hours... what next guys ?.

have you checked ur infra red setting? make sure its OFF! i think, it is turned on as default after flashing! or maybe your charger is defective! try someones charger!

IR disabling has not helped in the past. But i tried again but no much use. The equipment is heated up during normal usage time. Is there any thing more i can try before my BA becomes a history. ( BTW. the repair center refused take anything other than the screen changes and battery replacements. !!.. )

Any one having any idea how to reset the bios ?. I think my battery problems are related to trying out the Trial Version of Pocket Hack Master to overclock the PDA. I have uninstalled it long time back and may even have performed three to four times ROM updates but may not have reset the software's overclocking settings back .. ?!!...
BTW. The service center argued out that the any ROM updates other than official Imate ROM will void the warrantee and twice they returned without repair and attributed the the problem of heating to ROM updates... ( without even checking!! ...

I faced the same problem when attempted to upgrade my Harrier. I agree, that there must be an error somewhere in the device BIOS that cannot be that easily reflashed. Unfortunately, I could not find any solution and had to replace the useless phone that drained the battery within 4-5 hrs.

Yes the over clocking eatsup the battery as well as causes heating up the device. So better dactivate the over clocking..

is this the correct way to recover from battery drain?

I recently upgraded my wizard from a wm6 rom to another and started to notice the battery indicator dropping much faster if I'm on EDGE networks (but maybe also with GPRS, I'm not sure). Since I didn't flash to the official rom before, I thought I had the common battery drain, so I did this: full backup using spb backup, remove hardspl, flash to original qtek rom, hard reset, flash updated radio rom, softspl, flash to wm6 rom, hard reset, restore previous full backup.
The problem is that I'm still noticing the battery going down faster than before. I'm not sure about it, because with this new rom I have a more reliable way to measure the battery, but before flashing all over again and reinstalling every single program (lots of time) I wanted to ask if my method of flashing does solve the battery drain problem (and therefore this is normal for this rom) or if this method does not solve the problem and I have to do everything without the full backup.

- check if processor speed is always high. Latest BatteryStatus allows variable speeds according to the needs of the OS - calls it CPU scaler;
- check if bluetooth or infra-red are turned ON as they drain some energy;
- check the backlight. Mine is always at the minimum and works fine in almost all occasions (except under bright sun light)
- disable Today timeout
- check power drain with a new battery (if you can get one)
that's all i can think of. maybe others can think of other reasons.
good luck

maybe I didn't explain all... I know what can cause greater battery usage, and I try to avoid it, but comparing the previous rom with the new one it seems the new one uses more battery. I also know this can be a "feature" of the new rom and I don't mind about it, because it's really much better. What I want to make sure is that the battery drain is not caused by improper flashing, because that's just wasting battery for nothing.

ah, right.
I don't think there's such a thing as 'improper flashing' when the new ROM works ok. Except for not performing a hard-reset afterwards i guess nothing can cause that kind of power draining, although some have mentioned corrupted extended-rom but i can't vouch for that

Currently I DO think there is something like 'improper flashing'.
I've read about it in another topic as well.
Since I upgraded to WM5SE rev4 I suffer from a severe battery drain.
For some time I suspected my dual sim adapter (did change to that one about the same time as upgrade), but even without adapter the drains stays wel above 100ma!
Until now i have eliminated all other possibilities.
The best way to upgrade to any custom rom appears to be:
- Flash to an official ROM
- Flash the custom ROM.
I seems to have something to do with the ExtROM that sometimes get 'a bit' corupted causing tha battery drain. Flashing an official ROM makes sure youre device is all fresh before getting the custom things on.

ok, but I already did that. The problem is that I'm still seeing some battery drain, especially if I'm on an EDGE network. I just wanted to know if restoring from a full backup using spbbackup after flashing properly could be the reason or if I must find another cause.

Sometimes can be a Today plugin that is performing some task all the time and that might cause battery drain.
there used to be old topics on that matter so i guess you must dig and raise some dust to get it clear

now that you mention it... there is a new plugin in this rom, I'll disable and test. But I still find strange that when I'm on gprs the battery drain is almost inexistent, but on edge is really big

Did you solve your problem?
I can't!

I have experience some issues
When I started trying PDA VIET Roms i feel like I got a new device cause it has superior speed but its caused by An app called OmapClock PLUS that enables an overclock, thats why the speed but it has too many batt drain... so i leave the PDA Viet Roms... I always first downgrade to an original ROM Wm5 then upgrade to a Custom and then hardreset... of course sometimes with a batt at 55% (enough to flash) but Mr SVI on his first release BrightRom has too much Batt monitor... it causes too a batt drain cause the reload constantly by itself to show batt drain... disable all. and no more problems jeje even on his Hornet v1.1 it has drain for me.
Somebody tolds me that I need to reflash my device with a batt at 100% but i didn't prof that solution so if you like to check that. tell us how is it going.
Hope it was usefull.

Touch Diamond Battery Problem

Hi, I just got my diamond 3 days ago and it seems to be having some battery problems, even when on standby it drains very fast, how long should the diamond last on a single charge (on standby, talk time, with wifi, or bluetooth) is there a benchmark to compare with.

the battery is just 900mha, like Nokia N95, so it is a bit underpowered, I suggest you to activate all energy saving tips through the program "Advance Config" and if you don't use/need UMTS & GPRS just fix your phone to don't discover automatically GPRS (always through Advance Config) and to GSM band (setting > phone > band), these reduce battery consumption.
bye,
davide

thanks, I'll try that, but even when not in use, the battery drains 20% to 30% per hr. tried it 3 time, same result, doesn't even reach 4 hrs of standby time

really strange... in any case your battery should go better after some cycles, wait at least 2/3 weeks before care

It's because the battery (like so many other aspects of this phone) sucks.
I got the new extended battery but that's useless too. It comes with a new cover for the phone but the battery itself is just twice as fat, so you end up with a 'sleek' phone that has a hunchback sticking out of it very awkwardly.

yep, I don't like the new battery, it makes a different phone

I have followed most of the battery saving advice that the usual programs can set up for you. I would say my phone, if its *just* standby can go 24 hours with just losing one "pin" on the battery meter. That means no calls, no peeking at the screen, no sms or otherwise communication. Since its hard to do this I have just tried 24 hours. If left on true standby I would say the battery would last for days.

I have a car charger and plug the Diamond into it while driving and in the office it sits in a cradle, at least I do not have to look for it under a pile of documents when it rings. Plus it serves as a fancy clock too!
The battery bar goes rarely below 70% while not plugged in.
3G and WiFi are extremly power hungry so do not expect hours of entertainment while they are on.
Fat battery is a bad road to take, I remember old Axim X51v (also HTC) with a 2.2Ah battery, it was like a brick. It is better to have a couple of small batteries rather than one big one obviously unless you want to play games on a transatlantic flight or go hiking for a long weekend.
One thing to remember is that your runtime grows faster than the battery capacity which is caused by the fact that at a slower rate of discharge the battery has a higher capacity, so if the 1350mAh battery is not too big it may be a worthwhile choice, I would expect the runtime to go up by between 75-100%. I just wonder how much longer will it take to charge and also you can say goodbye to most of the protective cases.

Buy a solar panel for mini usb and glue on the back of the diamond, then you will have infite standby time when left in the sun

What rom do you have? maybe it needs updating?

I am using the Customised Comms manager and that's made a massive difference, basically 3G, Bluetooth and WiFi are off unless I need to use them.
I charged last night for the first time in 3 days, making calls and playing around in between

i get about 1.5 days outta my battery....
only running on 2g with light sensing on 20 or more sms a day with maybe an hour of phone calls all up.

i'll copy-paste my answer from an another thread:
using yr phone in a place where the reception is not good will drain yr battery faster.
i can add (there is a relation) that the level of radiation that any phone is emitting it is also higher when reception it is not strong enough. i've seen it demonstrated yesterday. entering in yr car double the level of radiation, in an elevator the radiation increases 10 folds! yr phone tries to connect and that's energy consuming and radiation emitting (electromagnetic).
i guess that you bought yr phone not too long ago. i know it sounds strange but after a few cycles yr battery's life is going to improve and i am not the only one to observe it.
don't stop the charging when the battery icon is full. i learned using a wall charger with LED (red for charging, green for charged) that after diamond's icon said 100% the charging continues for at least 30 minutes more (the led was not fully green but was blinking red-green).
from my experience u can use all power management option from shap's advanced configuration without loosing yr connectivity. i can not tell u what those option are but after using all i can tell that diamond's battery life improved.
with only 2G and some e-mailing downloading and checking this forum a few times my battery last for 1.5 days. of course their is also 1-1.5 hours of phone calls.
don't expect yr battery to last if you are using yr diamond as an entertainment center (movies and mp3) or as a battery only powered GPS navigator. i am using my GPS in my car always connected to my car charger.

I'm thinking about buying something like that to solve the problem :

Hi
Rom 1.37.707.1
Radio 1.00.25.03
I'm not yet sure what the problem was, but it has something to do with the sim card that I'm using, the sim stop receiving signal and I tried another sim. The battery life improved and now It last more than a day.
thanks,

I am getting about 48 hours (I probably talk less than 30 minutes in that time). Using default x04ht rom on diamond with radio 1.00.25.05 (just flashed to 1.08.25.20 and getting about the same). Charge every day isn't bad, but every 1.5 to 2 days for a device like this; no complaints.

Battery Drain on G1

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?

battery
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.

battery/charging problem.

i'm using donut's android build and this battery/charging problem is driving me nuts. my battery lasts 4-5 hours max and the weird thing is it only takes 10 -15 mins to show my battery is fully charged. i tried flashing again, left the phone until it dies by itself and charge it, left it being charged over night but none of them helps. anyone having same issue? i know with android on our vogue the battery life sux but is it this bad??

might be time for a new battery. It should take 30 to 45 mins to charge. And it should last longer than that. How much time do you spend playing games ect. Gps also is a battery drainer. Also alot of data usage.

My battery can last all or most of the day with moderate use on Android.
If you are running off an SD card, try booting back into windows for a day or so to see if you have a similar battery problem there too. Actually, windows battery life was MUCH worse for me. The difference is that Android does not wake the screen for Calendar alerts or text messages like WinMo does... though in Android you do still get the vibrate or sound alert.

win mo is actually quite ROM dependent (NFSFAN's ROMs got awesome battery life). android is pretty kernel dependent. if you are charging overnight, and using latest zimage/kernel, and turing off syncing (background data), and that is the battery life you are getting, you need a new battery.

i use gps a lot as i work as a field technician but i don't have gps turned on all the time while im driving as the screen shuts off by itself in a minute or so. maybe gps is still working even with the screen shut off? and it's a nand install so trying with winmo is not possible. i had much better battery life with winmo for sure. if i turn off the syncing will i still be able to use gps?

Which NBH are you using? The newest ones are way better than the older ones. If your using a current one check out tatnai's FAQ... http://forum.xda-developers.com/showpost.php?p=5599516&postcount=33

It's the kernel. you know the file you rename RUU_signed and you flash.

I am definitely having this problem as well, and the charge does not last very long it seems either. Was much, MUCH better in the Windows Mobile builds I was using previously.
I am on Bell using the basic HTC Touch

Same problem here. Brand new battery on bell.

Yeah, although battery life is positively improved and pretty decent now, there is definitely still something funky going on with charging. I still don't rely on / believe when the phone says it is fully charged. It happens too quickly to be possibly true.

I have the exact same issue and it is absolutely a problem with charging within Android. I have two identical batteries. One was fully charged in winmo before I flashed - I took it out and swapped for the other one. Flashed it with that battery in and charged it overnight. It only lasted about a half-day. Came home and swapped out for my other fully-charged (in winmo) battery, and it lasted for more than a day. Same settings, same use. After it discharged, I recharged overnight from Android and it behaved the same as the first - discharging in about a half-day.
What gives?
I'm curious what builds people are using? I'm totally new to this but I'm using warm donut with voguimg-240x320-06-04-10.nbh. It seems that nbh isn't posted on the sourceforge site yet - maybe I should switch back to an older one?

Maybe kernel problem.
I'm experiencing the same problem as everyone.
Lately my battery suddenly drops from 100% to 4%.
When I put to charge, it reaches 100% very fast. Should reach only 5%
I think it can be a problem in the kernel.
Now, i'm trying to solve it. If I find something I'll share with you
I can not determine which kernel brought the problem...
23/04 - 16:16 (GMT-3 - Rio de Janeiro) - Trying an old kernel
23/04 - 17:00 - Nothing. But came to the conclusion that the problem is with the battery.
Battery really "thinks" its 100% charged, since it accepts flash a nbh without the need of the phone is charging. And this only happens when the battery is at least 50% charged...

My battery life is pretty bad and I recently bought a new OEM battery. Coming of NSFANs 6.5 rom, Myn's warm donut on 240x320 is wonderful but the battery life is pretty lousy.
