Can acbPowerMeter be trusted?

Hi!
I have had my Tytn for roughly 2.5 years. This autumn/winter the battery time I could get out of my Tytn was really ridicilousley low, so I bought a new "non original" 1500 mAh battery. It got better but not much, I started to think that perhaps the battery time was never better than this.
The other day I skimmed through this forum about battery problems and found this little program for meassuring battery consumption. I have now had it on since I removed my phone from the charger this morning and now, 4 hours later I'm down to ~30% battery power and acbPowerMeter tells me that the phone has used 90 mAh all together.
I have made 1 shorter phone call and made a couple of synchs with turbo 3G during this period.
Does 90 mAh sound at all right? That would mean that the battery was crap to begin with....or is it possible that acbPowerMeter isn't giving me even "close to correct values"?
Does anyone have any comments or ideas around this issue?
Best Regards,
Olle

Don't know anything about your abcpowermeter. What I do know, is that when I've had a new battery, or when I flash a new ROM, I often have problems with low battery. I just run the battery down like three times in a row, and my battery always improves.
So before making any determinations or using a program, I always run the battery down.

I've got acbpowermeter on my phone, and I don't think it's much good to be honest. If I remember correctly, the last time I left it running, it severely drained my battery - not exactly what you want a power meter app to do.
I find it far more reliable by using BatteryStatus from chi-tai.info and just seeing what the momentary power usage is. (it sits on your Today screen). Yeah, it's not a comprehensive breakdown of your power usage over time, but it doesn't run the battery down like acbPowerMeter does
Like you though, I'm still curious as to what exactly my device consumes in terms of power over the course of a single charge, and I'm on the look out for a decent app which just ticks away in the background measuring power drain...

Hi!
Regardless of Acbpower I just bought a new HTC Original battery and now I have the "normal" battery life I was used to during the first year of my device. As it has allready been discussed in other threads: These non-original batteries are far from always a safe purchase...
Br, Olleman

I recommend Lion Batteries. I have had a great experience with their 3000mAh battery for over a year and a half. Use that 3G on my Hermes and music all the time -- serious user-- and the battery still last me over day. Mind you I am constantly on the internet and always using push email and other data-centric services.
As far as Battery Status, for general purposes is great as I find the more complicated the app the more drain on the system it is trying to read. A simple app that you can just keep an eye over a period of time I think works best.
As far as batteries I was concerned where to buy one. Since my brand new battery died over just a year. Mind you a tethered a lot and I think that tends to kill the battery life faster.

Battery Life

I've done a little experimenting, made a spreadsheet and all, to see what makes a difference to the battery drainage. Here are my findings -
Live Wallpaper: YES
Connection: 3G
Taskiller Widget: YES
Battery Drain: 7.5% per hour
Live Wallpaper: YES
Connection: 3G
Taskiller Widget: NO
Battery Drain: 4.5% per hour
Live Wallpaper: NO
Connection: 3G
Taskiller Widget: NO
Battery Drain: 4.4% per hour
Live Wallpaper: YES
Connection: 2G
Taskiller Widget: NO
Battery Drain: 4.15% per hour
On average, using one of the 4.XX% scenarios, if it was left asleep for the hour it drained battery 2-3% per hour.
Heavily used for the hour, browsing the web on lunch drained battery 6-9% per hour.
Mind you, today has been relatively light use all day, Live WP, 3G and I've got 3.7% all day. At this rate, I would probably get 27 hours use. The battery does seem to get better after a weeks use, so don't judge it straight out of the box. I know some people said using 2G would save battery, I was surprised how little it did.
One thing I used to do on my Hero to save battery was turn of auto rotate. Tomorrow I might try that and see how it helps battery life.
Are there any other things you'd like me to test?

I don't believe so, no. I might try again next week with them off, just to check it wasn't the battery getting better that scewed results, but so far, they look to make no difference

It seemed that the live wp drained my battery more when I used it, even when it wasn't on much. I may do another test to see.
I find that the battery lasts a little longer if you power the phone off before charging it. Today I've been streaming Last.fm, played about 20 minutes of Julelust in the bathroom and did quite a bit of GTalk chatting, and my battery is at 85% after about 3 and a half hours.

I wonder if it depends which LWP you use? I was using the Live Earth Wallpaper...
Also, I might try underclocking to 600mhz for a day, to see what that saves.
For me, I'll probably use it with all the bells and whistles on, even if I only get 20 hours life, as long as I know I'll be home to charge it that night. If I know I'm out for a couple of days, I'd like to know what settings I can change to extend it up to maybe 40 hours hopefully.
I should also do a day where I turn of data sync, I think that makes a big difference. If you turn it off with the power widget, will it stop everything using data? E-mail, apps, everything? Or do I need to actually turn data off for that?

Very interesting. Which task killer widget did you test? Thanks.

I think it was the one from ES Task Manager. Now I've got Advance Task Manager and just place a link to the app rather than the widget. It's still only 2 presses to kill everything.
I have the paid version of TasKiller, which I used for a long time on my Hero, I should test that at somepoint too...

nice topic.
Can you tell which Rom are you using?
Default?
Cyanogenmod?
Modaco?

I don't think this is relevant unless he's running a stock ROM with no 3rd party apps installed. Also, if you believe the battery gets better after a week of use then why perform any tests until after that week has passed???
This testing is flawed in another way; inconsistent usage patterns.

It surely is.
It changes many thing including if it's needed to kill an app to boost memory etc.

So leave the thread and don't be so negative.
Yes, Modaco's 1.5, some in Cyanogens. Why would an app in one ROM use more battery than it does in another? This testing was for me, why would I test in any ROM other than the one I use? I just thought others might benefit from what I found.
Why should no 3rd party apps be installed?!?! Some of these are what I want to test!
I did wait a week...
Of course there are inconsistent usage patterns. Even if you tried I bet you couldn't do exactly the same things every day at the same time with your phone.
This is not a scientific experiment, it's just my findings. I'm not claiming I can tell you how long your battery will last, as I said, I just wanted to know what things helped and what things hindered. Please have the good manners to not bothering to return. Thanks.

Current Widget and battery draw

So we all know that low numbers in current widget are good and high numbers are bad. Thing is, how do we interpret these numbers? I mean if my phone (HD2) is currently drawing 4ma how long should I expect it to last/how much percentage of the battery should it drop an hour?
What about when it's drawing 189?
How do you do the math to figure battery life out?
Its just been puzzling me...
Sent from my HTC HD2 using XDA App

Your battery is 1200mah, that's milliampere hour. So if you're drain 4ma, then it'll run at that rate for 1200mah/4ma = 300 hours. Same for your other numbers.

If only it would run at that rate consistently hey .

Its actually 1230mah

the important thing is that it shoud have the minimal drain at standby moments ... becouse when using the device ... it gets as high as 450 ... on top spikes usualy 200 - 350 so dome nice man should think about minimizing the spikes when used.
By the way my girlfrind just bought a wildfire ...stock and it gets like in stand by 25 - 50 ma and when using 200-300.
Mine with nand android gets like 2 - 5 ma with some little spikes at 30 sometimes.
pretty cool

Indeed it is ! i have both a desire and a hd2, i used the desire for months while waiting for magldr, that things never idled below 20ma to 40ma and with the screen on was usually 350ma to 400ma
now the HD2 with a bigger screen uses less, like 150ma to 250ma and sleeps on under 5ma lol !
the desire may have more battery (1400mah batt vs hd2 batt 1230mah) but it lasts allot longer thx to more efficient use.

One question from a noop.
If i enable bluetooth over different builds the battery drain is quit different.
With most of the HTC builds, like Desire HD i get a battery drain between 3 and 5 ma in standby. With Stock builds or CM builds i get 60 ma in standby?
Has anybody the same experiences or can explain this?
Best regards
trilu

same issue for me but i dont know why this happens

I had this with early HD builds too - I think it may be that it's not going into low power standby mode (just enough to keep connection active)?
Try wifi too - that should settle to 5/10ma if idle.

@ T.S.: You should try the Battery E.T.A. app: http://www.appbrain.com/app/battery-e-t-a/com.ac19.beta
This app shows you the current battery percentage + it displays a calculated "end of battery" time, based on your usage of the phone over the last day/2days/..

That happened to me too with DHD builds and i've tried many things.. the solution to stop the heavy battery damage (sometimes) was just opening wifi and go Idle

So let me get this straight: it is normal for my device to have 400 mA when using it?

Anyone think it's possible to get those "top" ma's down? Because it's draining like 350 ma in full use.. would be cool if we get it below 200 or something Maybe with something like those ultra low voltage builds that you had on the sd android version?

use setcpu and limit to like 400 mhz. it will be sluggish but u get your 200ma. also turn off backlight. but there's no point doing that.

Haha oke I get the 400 mhz.. but thats not what I was looking for

HD2 is the best Android phone on the market. Nothing compares to it besides the Evo and the build quality on those isn't as good as the HD2.

I've ran some tests before. With the phone idle and the screen at the dimmest setting, it drains about 100ma. Turn that up to full brightness and it goes up to 230ma. Phone calls have the screen off and it uses about 150ma or so. The rest is just how hard the phone have to work.
It's really not bad when you think about how much it does out of that little 1230ma battery. You can get close to 7 hours of talk or browsing at dim light. 12 hours of music playback, 250 hours of standby time. These are pretty good numbers. If you really need more than that in one day, you just need one of those extended batteries. I hear this one works pretty well in android without custom kernel

Battery indicator - setcpu - Juice Defender

Wrapping these all up in the same post because they are related.
I have found that the battery indicator is pretty inaccurate and will jump from say 15% straight to 10%. This goes for the stock battery usage meter in settings, display in the top right on the staus bar, battery widgets, and even setcpu. Anyway to make this actually accurate and provide real time indication?
Also I have been playing around with setcpu and Juice Defender and have found that they essentially do the same thing. They both under clock the CPU at certain times except setcpu doesnt disable wifi and other things. I figured it would be bad to run both so I disabled Juice Defender. If I have to pick one, which should I use?

circle battery widget can indicate the exact percentage.

circle battery widget and other apps only estimates the exact percent, the atrix hardware only allows for 10% increments.

Do you also use setcpu? Did you seem to definitely notice a difference using Juice Defender? Or more importantly any features of the phone change? For example every time you shut the screen on and turn it back on, does it have to find wifi again? Or what about when the screen is off, does it shut down data connections completely so that you don't even receive email notifications?
Sent from my Atrix using XDA App

I used Juice Defender on the atrix until recently. It worked well. I had to set to pull data for one minute every 15 minutes (and it wouldn't stop downloading at the end of the minute unless it was finished pulling what it wanted to. Sure I no longer got my email responded to the second I received it, but it made my battery last ~50% longer.
I also used setcpu to underclock when the battery was <20% and when the screen was off. Juice Defender has this feature for other phones, however, didn't seem to support underclocking on the Atrix.

Thanks for the info

I don't think people here realize how circle battery widget (and other like it work). Nearly all battery widgets just read what the system is saying which is obviously going to be in 10%'s on this phone. What circle battery and a few others do is read the actual voltage left in the battery and make an accurate % report which is why it's 100% accurate down the %. It doesn't matter what battery capacity the battery has either because every Li battery has the same full and empty voltage. So yes circle battery widget is 100% accurate.

^Exactly. Even without knowing that, you can just watch the circle battery widget and the reported system percentage. The circle battery widget always changes consistently with the normal system value, so at the very least it's as accurate as any of the meters displaying the 10% increments.

Not sure where you got the idea that circle battery widget was inaccurate. Like I mentioned above, anyone can observe that it is consistent with the system report, so it at least averages out to be fairly accurate for every 10% block.
Another thing to remember, though a small detail, is the fact that the system displays increments of 5% starting at 15%. That doesn't change much, but that means it's not only 10% increments.

im not saying you are wrong here but where did you get the info that it measures voltage? even if it does im not convinced its that easy to
accurately measure capacity. why are all these phone manufactures have problem with having to recalibrate batteries and wiping stats? why not just always measure voltage and always have accurate numbers?
im no expert im just going with what designgears posted in his thread. he is a developer that made lots of roms with very accurate battery monitor that i used for my captivate. he was trying to make one for the atrix but was told that the hardware only supports 10%. if its was as easy as measuring the voltage then why didnt he just do that?
ive used circle battery and battery monitor that both showed 1% increments for a few weeks and noticed that it was not very accurate. its hard to explain but when i was using the phone it would decrease at a steady rate then when i have the screen off for a few mins it would quickly drop 2-3% (within the few mins that i had the screen off) then it would slow down again, this is why i think its an estimate. dont get me wrong its not too bad for an estimate but if you ever used cognition rom or any other roms on other phones with good battery mods you will see what a really accurate battery monitor is, you can set a timer to it...

I've had a Captivate since release back on July 17th (or 18th I forget) so I fully understand who DG is (And I'm not to happy he jumped ship completely on this phone like he did but it's his choice and it is what it is). Ok so even though the hardware on the Atrix isn't capable of reading the battery in single percents only in 10's it still reports the actual mV of the battery. If you open "Spare Parts" app for example and go to "Battery Information" it displays your current mV of your battery. Now almost all modern Lithium Poly batteries are considered "Full" at 4.2 mV (Obviously this can vary slightly even within the same battery for the same phone model due to manufacturing tolerances) and "Empty" at 3 mV (I think it's REALLY dead at around 2.5 mV but the phone has a built in safety feature to prevent this because if it drops to low the battery wont even take a charge). Here's a link Lithium Poly Battery to this data. All the Circle Battery Widget is doing is assuming your battery is at 100% at 4.2 mV and 0% at 3 mV, then if just divides your current mV by 4.2 and turns the decimal into a percent and now you have your display %.
Now the reason it may drop faster like you said is because the phone OS itself reports the battery mV and I doubt it checks it every second. So say the phone OS checks the mV every 5 minutes (Just guessing I have no idea) and it reports RIGHT before you play a game or a few youtube videos then you stop playing (phone still shows the same percent) and put your phone to sleep then wake it 2 minutes later and now you've lost 2% battery "Doing nothing" but really the OS just didn't refresh your battery mV before you turned the screen off.
As far as how I know Circle battery widget does this is basically common sense, obviously it isn't it getting info directly from the system battery percent because it won't read any more accurate than 10's. The only way it could get even a relatively accurate percent is by the method I stated above because obviously most other battery meters are just repeating whatever the system is stating in 10's.
That's basically all I've gathered about how it works, I could be completely wrong and if I am I'd love to hear from someone who actually knows because I love to know how stuff works

can you share your settings for jd and setCPU when you used it? sounds like you had a tweaked out well.

Hello
I am the author of Battery Monitor (SIMMO Publications), if you're getting 1% values then your phone is either returning accurate values through the Android API, or there exists a system charge_counter file that is updated by the operating system. It does not estimate the value.
Motorola devices (Atrix, Droid2, DroidX), for some reason, choose to ignore the 1% values stored in this system file. The file is hidden, and not many people know about it (apparently). But it IS updated, so these 10% only Motorola devices are actually capable of 1% level changes.
I hope that helps.

Pathetic Battery Life on Vibrant Trigger

SGS Vibrant flashed with Trigger 3.2 the battery lasts for 1 day with wifi usage and even if kept for overnight it drains about 18-20% of battery should i move to a different ROM ?

You could
Sent from a cell tower to the XDA server to you.

Trigger has had one of the best all time battery life for me a everytime.
I think you need to
A) recalibrate
B) re-check to see if any apps are using battery life.
C) flash a rom if none of that works.

Here we go again for the millionth time.....

But for me trigger had the best battery life.
I'm not on the gingerbread roms and it takes me from 100% to 5% in 8 hours overnight even WITH Juicedefender (seems to be about the same without it also).
If anyone has tips on THAT, I would much appreciate it. I've tried calibrating the battery.

There is a setting that you can turn your radios of from x time to x time overnight. I have mine set for 11-6. If I am on after 11, then I take priority. If not then the setting does.
There is also a setting that will open data/radio every 15m/30m/45m/1h/2h or something like that to get updates for somethings (i.e. Beautiful Widgets). I have mine set at 2h. If I want my data/radio open I will do it myself, hence my long interval.
Been using this app for well over a year so I know how to tweak it a bunch. If you have JD+ see my battery guide and it will tell you more about its tweakiness.

Trust me. This guy knows how to use JD, check out his battery guide. It will be worth your time.

i wish i could get my phone to last a whole day without charging, i just dont complain because i know for a FACT that the reason my phone only lasts 10-12 hours is because of ME. im too stubborn and refuse to switch to battery-friendly usage. the biggest thing that impacts battery is the user/user apps. not rom, not kernel, the battery difference from rom-to-rom and kernl-to-kernel is barely noticeable (unless in the rare case where there is a bug, or developmental defect). if there was ACTUALLY a rom in exsistence that TRULY had superior battery life, then you wouldnt get 5-10 different answers in every single "what is best rom/kernel for battery" thread.
the problem is, people want to believe that they can save battery without changing their usage habits. this simply is not possible. no rom or kernel will realistically do this for you. if you remove 1 brick from a bag full of 15 bricks, the bag will be lighter, but still very heavy. you need to download "spare parts" or "process monitor" from the market and start analyzing the way your apps are acting. also look into data syncs that are happening in the background. apps that stay open behind your back/what they are doing, (an app called "autostarts" can prevent apps from self-running under certain scenarios). animation speed. polling for notifications. gps. wifi scans. overclocking. cpu/ram usage. proper sleep. widgets. brightness. 2g/3g. data usage. call time. text volume. - THESE are the things that really affect your battery life.
bottom line is, if you truly want to save battery you are going to have to get your hands dirty...there simply isnt a one-click (or one-flash) solution.

Hmm so i'm now on MIUI and it seems to be giving better battery life, also have been thinking of getting the extended battery for Vibrant is it worth ?

If it sucks so bad, grab one of these. I have it and it has given me at least a 20% increase in battery life. BTW, you must listen to the instruction for the Battery if you get it. 4 or 5 full Drains to 0% and then charge to 100% while device is powered off and re-calibrate after each of these full charge cycles.
