now I know there are many software out there that measures battery life, but non of them works very well on wizard
so Im thinking about making a program that runs on background and quickly drain the battery
we can then time the battery drain and post it on xda developers to compair
this way we can have a good measurement of how healthy the battery really is, and can have a good measurement on how much battery does todays plug-in or oampclock really consume
OR if anyone knows a good way to measure battery life, please tell me.
My phone has an autonomy less than 24 hours.
What is the best Rom,app or tips to increase the longevity of the battery?
this question is a bit too general, take a look in battery usage and see what is using your battery the most... this way we can see what the problem is and how to help

That looks pretty damn good.
I was just about to post a thread. Something is draining my battery life and causing Android System to be the highest battery usage. Check out below.

Can you repost your pictures? They don't seem to be working.

What is your brightness set at

Auto brightness.
Not to jack your thread.
But I used my iphone at work to watch videos, ect while there is downtime. I usually watch while it's also on the charger
For the Note series, does anyone know if that "kills" my battery for long term?
I know you can replace battery, but just wondering for future use.
Thanks.
Issue with battery drain due to android system is real
All three people I know that just got the Note 4 were experiencing the same issue I had with excess battery drain with the always generic "android system" taking more battery than anything else including the screen.
I downloaded an app called "System Tuner" and looked the CPU% for Android system and it was a constant 3-4% when the phone was otherwise idle.
I found a post at http://support.t-mobile.com/thread/80459 where they were experiencing the same issue (lose around 12% battery an hour with android system taking a huge chunk of battery). The person from that post was able to address the issue by turning location off, rebooting, turning location on, and rebooting again. After I did this I saw Android system idle at ~0.6% - 1.1% instead. So far I'm getting much better battery life but I'll need to give it some time to know for sure.
Hope this helps!
mine took about 2 full days for everything to finish syncing, downloading, indexing, etc. I had books, news articles, pinned music from google play, etc.
Once that happened, everything is now "normalized" and I'm getting better battery life than I was with the note 3.

Short answer: Maybe, it depends on how you are doing it. Using it while it is charging is not necessarily bad but watching videos and keeping it plugged in while the cell voltage is pegged at 100% will likely deteriorate your battery faster.
Long answer + tips:
Lithium ion batteries are great - they are light, can be made very thin and have excellent energy density but they are also very finiky.
Things to avoid doing with a lithium ion battery
-Charging to 100%, leaving it plugged in overnight is a poor practice(high cell voltages reduce the service life*, stopping the charge at 90%[4.10v] can double the service life, stopping the charge at 80%[4.00v] can quadruple the service life.*)
- Discharging the battery to below ~20% (Li-Ion batteries are somewhat sensitive to deep discharges)
-Charging/exposing Li-Ion to elevated temps or below freezing.
*service life is defined by when a battery can only retain 70% of its rated capacity. Most consumer batteries used in mobile devices have a service life of 500 charge discharge cycles.
It is not uncommon for batteries to lose 30% capacity in 1.5 years or less. Changing your charging and handling habits can double or quadruple a batteries life span.

LOL your picture took up have my damn screen on my 1080p laptop with 15.7 in screen. It was crystal clear too.
On my 2nd charge, auto brightness. Pretty freakin' amazing battery life....
15.5 hours off the charger with 8+ screen on time!
I got awful battery life on the first charge cycle. It drained 50% overnight. 2nd charge has lasted amazingly long and I still have 64% after 12hrs of average use.
First charge. Battery life has been phenomenal. Brightness on auto.
Did u use any power saving features to achieve that time?

Definitely improve battery with recent update and I'm a power user
After the latest update
I dont know why but my phone goes from 100-90 in less than a hr with minimal use while the screen is set at auto, also in the leaving it unplugged in the night the battery also drains like 5 points.
I've been at full brightness and using the hell out of it non stop so far, and I'm at 35% with screen on time at 3hrs 40 min.

can any one tell me how to solve the heating issue.and battery drain problem.
currently i am on stock latest rom.
i tried cm13 also but not fixed.
and dont know about Unofficial cm14, how much it is stable?
What do you mean with heating issue and battery drain.
- Provide logs,
- post pics of battery drain,
- show us what is draining your phone how much,
- how long your battery last on what use? low moderate high?
- How hot your phone get, use program measure temp and show us logs
- Etc Etc. provide more info overall, this is purelly asked
The heating issue had been there on the 2 since the very beginning. In Fact its not the phone's error, the problem is with the Snapdragon 810 processor. It is prone to overheating.
Regarding the battery drain however, can't comment without more info. Sorry.
One could say, the backside of having a powerful CPU in your device is that if you have apps going haywire, you will get a lot of heat and poor battery time. ?
I've had the phone just a week and if I am using heavy then the battery is pretty good, lasts 4 hours plus. Better than my G5.
However, if I am barely using and only sending the occasional WhatsApp and not much else, then the battery doesn't seem to last as long, for example it drained to 50% today with very little use, only 1 hour of SOT. Wifi and location were on, but Bluetooth off.
I've taken some screenshots of battery stars with gSam. Could someone help me decipher what is causing the drain? Or if this is normal behaviour?
Everyone is saying that this phone has amazing standby battery life because of 7.0, Doze, etc. So I am confused!

Looks like you have something running in The background keeping it from falling into deep sleep which is why. Unfortunately I suck @ troubleshooting these kinds of scenarios. My guess would be a Google service of some type. My brother had a problem with Gmail one time that was draining his battery while the phone was in sleep
