As we all know, we cannot access our batteries in this otherwise awesome phone. This is a first for me, so I am slightly anxious about the care of the battery as far as charge cycles and such. Out of the blue I decided to research an app for complete statistics and health monitoring and to my pleasant surprise I stumbled upon AccuBattery (Pro in my case). A full suite of standard charge and discharge statistics as well as a few extra features (that I personally haven't seen before as I am a little behind on this type of battery monitor development):
-built-in charge alarm (80% recommended)
-estimated charge cycle wear from current level to alarm level
-statistics per charge session (mAH measurements)
-estimated current capacity based on wear statistics vs design capacity
-current cycle usage per app (mAH) and deep sleep time
-battery wear and capacity graphs based on charge sessions and days passed.
-battery current, CPU processes and core usage system overlays (PRO FEATURE)
-tutorial and tip cards for ease of understanding
I still have yet to fully experience some of these features as they collect and build data through usage and charging. But I am excited to see how this turns out. If anyone is aware of a better or more complete statistics suite feel free to share or discuss

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.

Is there an app that measures the cumulative keep awake time per app versus time ... Along with battery percentage vs time. This would be useful in diagnosing apps that have excessive wakelocks and correlating there keep awake time periods with periods of excessive battery drain. As it stands right now with apps like better battery stats and the stock Android battery app,, you only know the cumulative keep awake or wake lock time as a single number rather than as a graph plotted versus time to overlay on top of the battery drain percentage graph. One always ends up speculating as to when that keep awake time actually occurred vs the battery drain.
So ideally I would want all of those statistics that come up in the stock Android battery app along with wakelock time, such as a CPU time total CPU time awake time etc versus time. A simple way to implement this would be to listen for battery percentage drops like many of the battery monitoring apps already do, but also record all of those other statistics and the current system time at the same time.
Is there anything already out there or anyone willing to add this functionality to their existing app?

Hello,
I have spent many hours of reading trough internet, including xda-developers forums and lots more. Maybe I'm not lucky and just didn't find the one right page/post where is what I need.
I have very simple problem, I suppose many people at some point gets to that question - is my phones battery in good shape and if I buy replacement is it at least close to promised capacity.
So only way to get that info is measure or approximate real battery capacity.
As there in system are available all required parameters for calculation - current, percentage/voltage and of course clock. It shouldn't be hard to calculate estimated capacity.
Of course it'll have to gather some data to calculate data, but it is quite simple, and can get more accurate as more data is acquired and saved.
I have found few projects who claims to do so, but unfortunately without luck.
Battery Monitor Widget - shows all data needed, but as capacity shows some kind of calculation between charge level and manufacturer/entered capacity, so it shows charge level in mAh, but there is nothing like estimated battery capacity.

Found post with Current Widget usage, but unfortunately it doesn't work for my Galaxy S5.
Post: http://forum.xda-developers.com/showthread.php?t=1019786
As conclusion, I suppose it shouldn't be very difficult to make such app, unfortunately I'm not developer and even familiar with mobile platforms development. Maybe there are someone who is interested in same stuff and can develop
Any comments are welcome
Cheers!
As Samsung declare, to extend battery life of your gear S, never recharge more than 80%!
I don't know why, but a Samsung engeneer teach me that this trick works perfectly on all devices, in SAM laptop, for example, user can choice this function from BIOS!
So charge until 80% and get out more than the original 100%??

Basically this trick is not to make the battery have a longer period before it drains to 0% but rather to make its entire lifespan longer. It's the same thing with draining if to zero. Ideally, lipo batteries would be kept at their nominal voltage (40-50% on most batteries) in order for them to have the longest life.
Hope that helps.
Thank you for the tip!

m0nz thank you very much for the tip !
I normally follow these tricks on increase the battery life of Android devices
Adjust the brightness
The display on your watch doesn’t always have to be super bright, especially if you’re indoors most of the time. There are usually five or six levels of brightness depending on the Android Wear watch model, and the default is usually a setting of 4. A setting of 3 is a happy medium, but you can probably get away with a level of 2 most of the time.
Turn off Tilt to Wake Screen
Tilt to Wake will automatically wake your watch when you hold up your arm and tilt it towards you. A very useful feature, but you might find that your display actually turns on a lot of times when you never intended to look at it. This might seem harmless, but it adds up over time and will lower your battery life.
Block unnecessary notifications
Getting notified about new emails, reminders, the weather, and other important stuff are crucial to your experience with Android Wear, but there might be notifications that aren’t as significant. Blocking those that aren’t will reduce the amount of time your watch wakes up.
I normally don't let the battery runs under the 20% of charge for smartphone and smartwatch too....

That's not a batter management tip - its a tip for the Samsung designers to get a clue and improve the detection algorithm. This is a problem on many Samsung devices I have hard - they bungle the face, motion and light detection algorithm, so the phone is always slow to detect you when you do need it, yet there are far to many false detections.
"Android OS" Process Taking Almost All The Battery Usage Percentage During Standby
Hello! I have a question regarding the behavior of an Android system. I've seen many people reporting not only high battery usage from the "Android OS" process, but abnormal drainage as well. So my question is - is it normal for the "Android OS" process to have the highest battery percentage (without abnormally draining it) IN STANDBY, in Android 6? I'm talking about a situation of "pure" standby - no running and no useless background apps.
I'm asking because... for instance, I have an Android 4.4.2 (KitKat) phone as well, and when it's on standby, well... something has to consume the battery, right?... Even if it lasts 15 days or so in standby. So KitKat reports the highest percentages to be occupied by "Mobile standby" and "Phone idle"... it's a 50/50. No other process (including "Android OS") appears in the calculation.
I can assume that Android 6 has different algorithms for calculating battery usage than Android 4. Those stats seem to be more shallow and lossy at the 6. I'm saying it because I rarely see any app appearing in those stats, even after heavy usage.
Also, I made a clear distinction between abnormal drainage and a high battery usage percentage. (As long as a system is on, some process has to consume battery in order to make it "ready to go" and be able to keep it on standby.) My Android 6 system is not abnormally drained by that process... it's just that it has the highest percentage, followed by "Cell standby" and "Device idle". Is it normal? For the record, the Android 6 device I'm talking about is an Asus Zenfone Zoom (ZX551ML).
Many people reported high battery usage by "Android OS" and inexplicable drainage (Some couldn't get it to stay even a day in standby) as well from the mighty Zenfone Zoom, but during testing, my device turned out to be able to resist almost a week (if not more if I used it less) in a "pure" standby state (all the major functions were turned off - Wi-Fi, cell reception, NFC, touch gesture support, automatic brightness; also, I had no running apps). Of course, "Android OS" was reported to be the most consuming process in terms of battery power. I can assume it's a normal behavior and not an issue. Or... is it?
Even when I used it a bit, with some apps on, it was still a battery beast in standby. I attached some links to screenshots in the post, to make it more accurate and show what the approximate proportions between battery usages are.
[No, I didn't attach any links. They won't let me post links yet from spam control reasons... And not even attach damn images!]
I am making a call to you because I've seen very poor assistance on the official Asus support forums - very mediocre and unprofessional assistants with an overall poor technical sense and perception. You have an example of that particular issue (the abnormal drainage) here - [Ah, they don't let me post links yet! I'm a new member.]
I just want to shed light on whether such high battery usage from "Android OS" is normal or not (in a standby scenario, of course). Heavy draining in standby is clearly abnormal [as what the guy from that forum (the missing link) experiences].
I have to say (not that you wouldn't know it already!) that this combination of an Intel processor, a device of such huge proportions as the Zenfone Zoom and a 3000 mAh battery is not going to be a happy combination in terms of battery autonomy DURING USE. When I use it, I lose battery bars pretty quickly (It's expected from a such configuration; the Intel machinery is not very conservative in terms of power), but in standby and with little use, it can be an autonomy beast!
