I was talking to a friend of mine about the Atrix's battery meter being only 10% increments, and he told me the Rhodium originally had something similar, until the battery driver was replaced.
Just curious, is the same possible here?
Please post questions such as this in the general forum.

You could also point him to the discussion about this. This has been brought up and is not possible. Hardware limitation.

Bah, I was hoping that a hardware limitation wouldn't be the case.
I saw that the voltage was available through /sys, would it be possible to create a more accurate meter through that?
Use "Battery Left Widget" (Avail on the Market) and once trained it will give you a fairly accurate percentage of battery life left.
Circle Battery Widget also seems to give an accurate readout.
Seeing the same thing here...Seems like circle battery shows 1% increments in line with the 10% increments in the battery manager.

My battery meter is way off my actual batery level? When I have 25 percent, the battery meter will show over half?... I have tried the "recalibrate your battery" tutorial...however it does not work..
I am running stock android 2.1 please help
Thanks, mike

Are you on the stock vibrant firmware? If you are, there is nothing you can do, the battery icon just sucks.
1. Wrong section
2. There are battery mods to correct this
3. I kind of like it that way. Placebo for awesome battery life
4. What's a SGH-T959D?

Canadian Telus Fascinate (Vibrant, with Normal North American 3G instead of AWS. )
Basically, Captibrant.
But I call it the Fascibrant, since telus calls it the fascinate but it's really a modified Vibrant.

"Battery recalibration" can cause the problem that you describe. I have written a technical description of this at:
http://dl.dropbox.com/u/12962476/Battery_Conditioniing/Battery_Conditioning.pdf
It is likely that clearing your battery stats and then rapidly discharging has biased your battery stat tables away from the reality of a normal discharge cycle. If so, that condition will correct itself over time (days or weeks). To correct it more quickly, I suggest that you discharge your phone completely and then clear battery stats as soon as you plug it in to charge. (That is, discharge completely, plug into charger, boot immediately, then clear battery stats immediately.) Then just use your phone normally and the battery stat tables will rebuild themselves over a few days according to your particular usage patterns. The battery meter should become increasingly accurate as the tables rebuild.

eugene 373 was at one point working to lower shutdown voltage. has any one else looked into it? getting that extra .5v would make a huge difference to batt life
I would be interested also.

It is a waste of time. battery voltage vs current capicty in a lithium battery dictates that it may give you another 5% battery life. 10% if you are lucky.
View attachment 479273
in actual use if LI-PO battery's (like RC cars) people usually only discharge them to 3.2 V and usually consider anything at or below 3v will cause cell damage. This is from real world use, not humdrum engineer info.
here is some good info on Li-Po's and other battery's in general
http://www.mpoweruk.com/performance.htm
Google Li-Po discharge voltage and you will find lots of info on the net about it. to me another 5% isn't worth buying new battery's on a regular basis.
on the hd2 ive ploted run time with various kernels. some with 3.6v shutdown some with 3.0
time to 3.6 was almost allways close to the same, but 3.6-3.0 allways netted me atleast 25% more life
and yes i have read extensivly on li-io and lipo batterys, keep in mind those two are drasticly diferent in charge/discharge.
and the battery in the vib is a li-io... i belive the iphone is currently the only phone useing li-po's.
This mod is complete already I believe and also produced great results. Problem was that it was done with I 9000 source. I'd assume we won't see any further with this until the vibrant source is available.
Hi Razr-Users,
I stumbled upon a review, which said that the Razr measures the battery life in 10%-steps. Even with apps, that replace the battery icon, it will still show the steps in 10%. The fact, that I read this just one time in a review, makes me wonder if this is true.
Can somebody confirm this for the Razr XT910?
I read that review too, but they are wrong.
I use Circle Battery Widget, and it shows perfectly in 1 % increments.
Actually, I'm very positively surprised by the battery performance.
There is a long thread in the Atrix subforum where a guy called shoux found a way how to modify services.jar and framework-res.apk in order to have the stock battery icon displaying 1% increments as well. I already sent him a note and asked him if he could do the same changes to the Razr's files if I would send them to him. Maybe he can help us out.
Need to deodex to have this feature

If you want a taskbar icon in 1% increments you can use the battery circle app (free on market).
I have the app, but how do I put the icon in the task bar? Thanks!

Do you have the battery cirgle application? You don' have to do anything, it places the icon automaticaly
I'm not sure that they would change measuring algorithm just on Razor, cuz it depends on the Android system mostly and on the battery controller in the phone. Definitely in 1%.
Yes it's the battery circle app. But I see nothing I. The task bar..... Hmmm
Sent from my DROID RAZR using xda premium
battery circle doesnt show 100%, is that correcT? it only shows max 99% for the razr even with battery wipe stats.
It showed 100% for me. I just waited a little longer when the stock icon already reached 100%.

Thanks a lot, I already thought that this is more like the Razr. Even though most of the reviews mention poor battery performance, I'm still waiting for some posts about the reallife performance.

Will have a look into it, sounds good.
@all: Thanks a lot for the infos!
Its weird. A few apps that I have used on multiple other android devices are reporting the battery level only in 10% increments. The circle battery app does show the correct percentage but why do these other apps not show the correct percentage? Whats different about the Razr from every other phone?
The two apps i'm referring to that show 10% increments are:
SiMi Clock Widget
BatteryLife
Can someone else try these and tell me if they have an answer to why they arn't working correctly. I would like to use the SiMi Clock Widget if we can figure out why the battery is only showing at 10% increments.
Here you can find a good explanation why this is.
You can only change the increments of the battery with a custom rom.

I have installed the BatteryLife app on multiple devices with stock roms on them and the battery increment has always been at 1% intervals. The Razr is the first phone (or tablet) I have seen that does it by 10%. So again why is the Razr different?
My XT910, running Stock 4.0.4. rom is also displaying battery levels in 10% increments. Anyone find out more about this?
Thanks
Does anybody know of a reference on the battery stats, specifically the graph and below noted detail.
For instance for the Mobile network signal there is a long green bar which I presume when GSM signal was active but there are tiny brown strips in there as well. What do these brown strips mean?
For the Awake and Screen on stat I presume each area in blue indicates activity. But how does this help as I though when the screen is on automatically the phone is awake as well?
Aside from getting another app to make more sense of these stats is there no way to even attach time to these stats? Is there another hidden way where better battery stat information can be gathered (again without any third party app)?
- Grey bits in the mobile signal indicate when you switch from 3G to 2G, or it means the signal is weak - I forget which, probably the former
- You'll notice that Awake and Screen On do not always match. There will be times when the phone is awake but the screen is not on. These are called Wake Locks, and they're pretty normal, but minimising them does help battery life for obvious reasons.
- In answer to your last question, install an application called Better Battery Stats. There's a thread on here somewhere that should help you - have a search.
For what it's worth, your battery life looks pretty good considering how much you appear to be using it.

Thanks for the reply. Searched the forum but looks everybody just reverts back to some or other app for battery stats. Seems the default battery stats are undocumented or something I need to search on the Android development forums?
Most people should be getting the Nexus 6p right about now or already recieved it. Please post your battery life screens here and please include screen on time and overall battery life.
Indicate standard attributes to make this easy.

I suggest updating your original post with what people should be posting when they report their battery stats. Here are my thoughts:
Screenshot: Battery stats window with list of draining apps
Screenshot: Screen on time (SoT) (press the screen line item in battery stats window)
Screenshot: Battery graph (click on the graph)
Location services: High accuracy, Low (network) or Off
Brightness adaptive: On or Off
Brightness slider (closest approx): 33%, 66% or 99%
Mention in body of post: SOT in hours
Google+ Locations: On or Off
Google Now: On or Off
PS: I will meet mine on Thursday night. It is sitting at home right now
There is already an active battery life discussion thread linked below. No need for another.
