Does the powerchart in this app work for the HTC Wizard...more specifically the 8125?? I ask because several months ago i read a review stating it was not compatible.

Battery Stats Collection - Lets figure it out

So it seems like their are a lot of differences in battery life throughout the forums so I thought it would be a good idea to collect some info and try to see if we cant figure out whats causing the issues.
EDIT: nevermind lets post this to a google spreadsheet for easier analysis. After you post to the spreadsheet... please post your timestamp. For example I am the first to post so my timestamp is: 10/22/2010 10:12:29.
Here is where you can post your info: https://spreadsheets.google.com/viewform?formkey=dHROU2ZPU09QYUpZYy1wZFR0UnhYRlE6MQ
Here is where you can see alll the info: https://spreadsheets.google.com/pub?key=0Alh-Zvy4QoLbdHROU2ZPU09QYUpZYy1wZFR0UnhYRlE&output=html
Here is an analytics thing: https://spreadsheets.google.com/viewanalytics?formkey=dHROU2ZPU09QYUpZYy1wZFR0UnhYRlE6MQ

Battery Info
What is TWS (Time without a signal):
Go here: home->settings->about phone->Battery use-> cell standby
The theory is that if you have a high percentage of TWS, that probably means your phone is spending a lot of time looking for service. This may be because the phone is set to wcdma or unknown (you can see this by dialing *#4636*1111# then clicking on phone info). In theory, if the phone is constantly searching for different towers (maybe gsm) then it will use a bunch of battery.
Discussion on TWS:
http://forum.xda-developers.com/showthread.php?t=772571
The "air plane fix":
This is a method of resetting the radio. This seems to make the TWS stop getting so high. Their are claims that this helps battery life.
- turn on air plane mode
- wait 15-30 seconds
- turn off air plane mode.
------------------------------------------------------------------------
This info below is just for reference... it is some of the stuff that I think we should collect.
So... here is some info I think we should all start to post.
Facts:
First, dial *#4636*1111# and click on battery information. Post the following when unplugged:
- Battery level
- Battery health
- Battery Voltage
- Battery temp
Now hit back and click on phone info.. post:
- signal strength
- network type
- gsm service
- gprs service
- Set preferred network type (wait 5 seconds or so, this will probably turn to unkown)
Now go to home->settings->about phone-> battery use
- tell what the top 4 items are in order
Then click cell standby and post:
- cell standby percentage
- time on
- time without a signal
hit back then click on voice calls and post:
- voice calls percentage
- time on
What rom are you using
What kernel are you using
What battery "tweaks" do you use (airplane trick, drm disable, etc...)
Do you use any software that may help (juice defender, tasker, auto start killer, auto task manager, etc...)
Do you have stock battery?
Opinions:
How many hours do you get out of your phone in a normal day?
What does your "normal" usage look like?
Is their anything else you want to tell use about how you use your phone?

Its a good idea, but there are just too many variables. I get amazing battery life, and I know exactly why I do. I use the Mixup Kernel, which lowers the voltage on the processor. I use SetCPU, which lowers the clock speed of the phone when its not needed. I use juicedefender, which turns off the radio and wifi when not in use. I have brightness set to automatic, and since I have the Mixup kernel, it works flawlessly.
Now people with push email who have their data connection always on and have facebook, twitter, etc auto updating constantly will have atrocious battery life. I can easily get 24 -36 hours out of mine sending about 50 texts and making 5-10 calls a day with some light browsing and game/music playing.

Yeah, I agree that there are too many variables. But I think all the items you mentioned really have little to do with it for those of us w/ extreme battery loss. Mainly because I have done all those things and I still saw my battery plummet.
Although in the end, it could just be that those of us w/ terrible battery... might just have defective phones.

Battery use not showing apps

Hi,
I noticed that most users can monitor their app, services battery usage through the default settings>about>battery use.
However, mine shows only display, idle, standby and calls. Do I have to enable something to be able to see them?
Bought the Galaxy S 4 days ago. Ex iPhone user, got tired of apple and decided to try android as an alternative. So far so good.

*#*#4636#*#*
Battery history and show the partial wake and cpu and 'other' usage gives a much better picture of battery eating apps than that battery usage one (this menu is exposed in the likes of Android System Info app, or Spare Parts, or SGS tools)
Sent from my GT-I9000 using XDA App

Under 2.2 the battery history is not really detailed and just shows things that used a lot of power, in your case (and everyone else's) the display uses the most power and after that comes usually the radio and calls. If you want more details follow the instructions above or charge the phone and play 15min of angry birds or so, that should show up

Cool. Thanks guys!

[Q] Get screen on time.

I would like to make an application monitors battery usage and stores some info in a database. I don't know how to get the "Time on" info for the display. It's in the stock battery use application.
TL;DR : How to get time display has been on since last recharge? Thanks.

Battery analysis help needed

Ok, this might seem basic, but I haven't had a Samsung in a long time. On all other phones I had, I had a battery graph that showed additional information underneath. I'm mainly interested in awake.
BBS randomly stopped working. It only says no statistics gathered yet. I need to figure that out too.
Mainly I feel my phone is not sleeping properly. Any Tipps on how to analyze this?

The battery graph can be seen if you go in to settings and then "Device Optimization". Click on the battery option. As for BBS, you need to provide adb permissions to access battery stats. Just seach XDA or Google it out on how to do it on a non-rooted device

I know that graph. It just missing the additional information below that stock Android has.
I am rooted and know that BBS needs permissions. It worked fine until 4 hours or so ago. Might be because i was topping if the battery. I just charged to full and will see if it works.

Ok, after full charge BBS is back to normal. Seems no drain is happening and phone is sleeping fine...
