[Q] Battery life statistical analysis tool ? - Galaxy S II Q&A, Help & Troubleshooting

Starting to mess with my new SGS2, flashing and stuff.
So i figured at some point i'll have to settle on something usable in real life and that includes a fair battery life.
For that one may need an application to gather battery drain statistics over prolonged period of time. In graphed form, with apps draining, charging, trend analysis, reboots/loss of power, etc.
Is there such a thing ?
At the moment i got the DarkyROM2 and it has the short term battery graph. But i want something to span as long as statistics are being gathered (weeks ? months ?)
Ultimate case analysis app of power consumption ???

In my opinion, Battery Monitor Widget Pro is the best battery monitor + including graph with voltage usage, percentage, etc ... it also include battery calibration tool too..
but it dont manage apps that running. in that case, install "watchdog" to manage whats apps running,ram usage,etc ..
both apps is a must in your case.

watchdog by zomut llc ? too much watchdogs on market

Better Battery Stats is what you need, only.

Monitor your O2 ATOM Battery consumption and post results!

I would like to suggest that everyone monitor their battery consumption patterns using acbPowerMeter. Its a good program to use and study how much battery is consumed while using different sets of programs on your ATOM. Also monitor yr battery usage while making calls, or sending messages out!
Post your battery usage graphs out for the rest to see and mention what program you were using when the battery peaks! This may help all of us to identify the heavy battery consumers!
Here's my acbPowerMeter graph on battery power usage...
1) First increase usage is when I wrote an SMS and sent it out -avg 150mA
2) Second major peak is when I made a phone call - avg 200mA
3) When my O2 is toggled off (idle, or when screen is switched off) - 5mA
Attached is also the acbPowerMeter program!

[Q] How do people know if an app is draining their battery or not?

Often on the marketplace, I see comments such as "drains battery" or "saves battery" for many apps, such as task killers. Now, aside from the "oh look my battery seems to last longer" or "oh look my battery seems to suck now" subjective point-of-views after installing apps in question (there are various different reasons as to why battery performance can differ from day to day), how do people evaluate the effect of an app on battery? AFAIK if an app is not listed under "Battery use", then it has little to no effect on eating the battery (I don't know about helping battery usage).
Any input?
I use a fairly simple strategy to maximize my battery life. Two key applications help me wring the best life I can out of what I have going (Juice Defender and Spare Parts). Juice Defender presents a limited window of opportunity for background apps to sync themselves when the phone is asleep which helps with partial wake usage. Spare Parts allows me to examine relatively detailed statistics of what uses the battery when. And again partial wake usage seems to be the critical area one can take control of.
You can get some more detailed info about battery use with Spare Parts of course but probably the most important area to try to glean info from is "Partial Wake Usage". In order for many apps (news, rss, social networking services etc..) to function they have to periodically update themselves and most will do this from a partial wake state if the phone is off and in your holster or pocket. How efficiently these types of apps wake up get what they need and let the phone go back to sleep can have a huge impact on your battery life. How often these types of applications update themselves also plays a critical role in battery life as well.
I have generally excellent battery life, especially given all the apps I have that frequently update their data (Facebook, Twitter, Myspace, Daily Briefing, NewsRob, Engadget, Fmylife) and the fairly frequent texts and calls I get.

I agree. And I don't see how automated task killers can benefit our android phones.

[Q] Battery Plotting App

I currently use Juice Plotter when diagnosing new apps & software power usage. Have read there may be a 'better' app out there for this task. Apparently Juice Plotter uses a good amount of battery on its own

[Q] Best app for tracking battery use?

The Prime still doesn't have battery stats showing which apps/services are using the most battery, and I'm finding that while mine lasts forever on standby, it's burning more battery than I expected in actual use.
What's the best app for tracking battery use by app? Thanks!
Anybody? (bump)
Battery monitor widget would be my pick

I'll give it a try, thanks!

Better Battery Stats
Has things like wakelocks, and CPU use per app.
SystemPanel too.
Okay, thanks for those as well. I think I need to see which apps specifically are burning battery life, because Battery Spy is showing me burning between 15% and 20% per hour. That just seems way too high for simple browsing and RSS feed reading.
Battery Spy just links to Settings, which of course doesn't show anything about apps. Really wish ASUS would get that fixed (took 'em a couple of months with the original Transformer, if I remember correctly).
reach out to Asus and tell them to address the issue. ICS (and HC) handle Battery data info and they did not add the function to their kernel.... tell them to get on it.
you can try juice plotter. also you might be interested in current widget (search them on the android market)
I use System Panel in monitoring mode. It works pretty well. The UI isn't tablet-optimized, so it's slightly awkward, but it's not too bad.
I always use Battery Monitor Widget.
Thanks for all of the suggestions. So far I'm not finding any app that's the culprit here (if there is one), but I am finding that the Prime in ICS (and maybe in 8.8.3.33 before it) spends more time at 1200MHz than lower speeds. I seem to remember that being different from the previous HC build.
I think ASUS still needs to make some adjustments to how the Tegra 3 manages power states, and that currently it's biased too much towards performance. I've also noticed (so far) that Power Saver mode doesn't seem to make much difference.

How does android / smartphone OS determine "battery health"?

So take apps like Ampere for example, they show some battery-related stats, one of which is battery health. I've yet to see any other value than "Healthy". So wondering how does the app / system determine the battery to be in good shape or not? Does it calculate the current maximum charge the battery can hold and compare to maximum, something like 2970mAh / 3000mAh can be considered healthy? Does it use the voltage value? Does it just use the temperature?
To provide context, my Note 5 is feeling like the battery has gone bad, I'm getting very limited screen on time even with light usage. Ampere and similar apps still show my battery as "Healthy", so I don't know if it's just a bogus stat or something scientific and can be trusted (which means my problem lies in something software-related).
Thanks for any input!
