I have a battery widget that showing me very slow charging speeds and very high drainage under little use such as phone idle? any reason why?
What does spare parts battery info say? Is it just the widget or actually battery issue? Have u wiped your battery stats in recovery and done the battery cycle process?

Wrapping these all up in the same post because they are related.
I have found that the battery indicator is pretty inaccurate and will jump from say 15% straight to 10%. This goes for the stock battery usage meter in settings, display in the top right on the staus bar, battery widgets, and even setcpu. Anyway to make this actually accurate and provide real time indication?
Also I have been playing around with setcpu and Juice Defender and have found that they essentially do the same thing. They both under clock the CPU at certain times except setcpu doesnt disable wifi and other things. I figured it would be bad to run both so I disabled Juice Defender. If I have to pick one, which should I use?

Just as accurate as circle battery?
Just out of curiousity, does anyone use Juice Defender?

circle battery widget and other apps only estimates the exact percent, the atrix hardware only allows for 10% increments.
This is not what I have found with circle battery and battery monitor by simmo. They show exact percentages on my phone.

Do you also use setcpu? Did you seem to definitely notice a difference using Juice Defender? Or more importantly any features of the phone change? For example every time you shut the screen on and turn it back on, does it have to find wifi again? Or what about when the screen is off, does it shut down data connections completely so that you don't even receive email notifications?

I used Juice Defender on the atrix until recently. It worked well. I had to set to pull data for one minute every 15 minutes (and it wouldn't stop downloading at the end of the minute unless it was finished pulling what it wanted to. Sure I no longer got my email responded to the second I received it, but it made my battery last ~50% longer.
I also used setcpu to underclock when the battery was <20% and when the screen was off. Juice Defender has this feature for other phones, however, didn't seem to support underclocking on the Atrix.
Thanks for the info

they will show 1% increments but these are just estimates as the atrix hardware cannot show 1%. programs like circle battery widget are not accurate even when they are showing 1%. check out the thread below.

they are pretty DAMN accurate, Ive been using the circle batt widget for almost a month now.
I switched to the simmo one since it has a notification bar batt %

I don't think people here realize how circle battery widget (and other like it work). Nearly all battery widgets just read what the system is saying which is obviously going to be in 10%'s on this phone. What circle battery and a few others do is read the actual voltage left in the battery and make an accurate % report which is why it's 100% accurate down the %. It doesn't matter what battery capacity the battery has either because every Li battery has the same full and empty voltage. So yes circle battery widget is 100% accurate.

^Exactly. Even without knowing that, you can just watch the circle battery widget and the reported system percentage. The circle battery widget always changes consistently with the normal system value, so at the very least it's as accurate as any of the meters displaying the 10% increments.

Not sure where you got the idea that circle battery widget was inaccurate. Like I mentioned above, anyone can observe that it is consistent with the system report, so it at least averages out to be fairly accurate for every 10% block.
Another thing to remember, though a small detail, is the fact that the system displays increments of 5% starting at 15%. That doesn't change much, but that means it's not only 10% increments.

im not saying you are wrong here but where did you get the info that it measures voltage? even if it does im not convinced its that easy to
accurately measure capacity. why are all these phone manufactures have problem with having to recalibrate batteries and wiping stats? why not just always measure voltage and always have accurate numbers?
im no expert im just going with what designgears posted in his thread. he is a developer that made lots of roms with very accurate battery monitor that i used for my captivate. he was trying to make one for the atrix but was told that the hardware only supports 10%. if its was as easy as measuring the voltage then why didnt he just do that?
ive used circle battery and battery monitor that both showed 1% increments for a few weeks and noticed that it was not very accurate. its hard to explain but when i was using the phone it would decrease at a steady rate then when i have the screen off for a few mins it would quickly drop 2-3% (within the few mins that i had the screen off) then it would slow down again, this is why i think its an estimate. dont get me wrong its not too bad for an estimate but if you ever used cognition rom or any other roms on other phones with good battery mods you will see what a really accurate battery monitor is, you can set a timer to it...

I've had a Captivate since release back on July 17th (or 18th I forget) so I fully understand who DG is (And I'm not to happy he jumped ship completely on this phone like he did but it's his choice and it is what it is). Ok so even though the hardware on the Atrix isn't capable of reading the battery in single percents only in 10's it still reports the actual mV of the battery. If you open "Spare Parts" app for example and go to "Battery Information" it displays your current mV of your battery. Now almost all modern Lithium Poly batteries are considered "Full" at 4.2 mV (Obviously this can vary slightly even within the same battery for the same phone model due to manufacturing tolerances) and "Empty" at 3 mV (I think it's REALLY dead at around 2.5 mV but the phone has a built in safety feature to prevent this because if it drops to low the battery wont even take a charge). Here's a link Lithium Poly Battery to this data. All the Circle Battery Widget is doing is assuming your battery is at 100% at 4.2 mV and 0% at 3 mV, then if just divides your current mV by 4.2 and turns the decimal into a percent and now you have your display %.
Now the reason it may drop faster like you said is because the phone OS itself reports the battery mV and I doubt it checks it every second. So say the phone OS checks the mV every 5 minutes (Just guessing I have no idea) and it reports RIGHT before you play a game or a few youtube videos then you stop playing (phone still shows the same percent) and put your phone to sleep then wake it 2 minutes later and now you've lost 2% battery "Doing nothing" but really the OS just didn't refresh your battery mV before you turned the screen off.
As far as how I know Circle battery widget does this is basically common sense, obviously it isn't it getting info directly from the system battery percent because it won't read any more accurate than 10's. The only way it could get even a relatively accurate percent is by the method I stated above because obviously most other battery meters are just repeating whatever the system is stating in 10's.
That's basically all I've gathered about how it works, I could be completely wrong and if I am I'd love to hear from someone who actually knows because I love to know how stuff works

can you share your settings for jd and setCPU when you used it? sounds like you had a tweaked out well.
Hello
I am the author of Battery Monitor (SIMMO Publications), if you're getting 1% values then your phone is either returning accurate values through the Android API, or there exists a system charge_counter file that is updated by the operating system. It does not estimate the value.
Motorola devices (Atrix, Droid2, DroidX), for some reason, choose to ignore the 1% values stored in this system file. The file is hidden, and not many people know about it (apparently). But it IS updated, so these 10% only Motorola devices are actually capable of 1% level changes.
I hope that helps.
It is still early days, but I thought I'd share this with all Android users on the HD2.
Like almost all members here, I flashed my HD2 to Android, now using a ROM on the SD, which takes up more battery power. Like almost all users, I too got battery draining issues. So I bought an original HTC 2300mAH battery, and.... no difference!
After installing a simple app called Battery Monitor (NOT Battery Monitor Widget), and changing the battery reading to volts within the app, I continued using the phone. The app showed, at the time of installing, 85% and the standard icon showed 43%. I disabled power saver and continued using the phone ignoring all battery warnings. The battery monitor showed 65%, when the standard icon showed 3% late in the night. I kept the phone on all night with syncing on, expecting the phone to switch off, but, in the morning, the standard icon showed 2% and Battery monitor, 58%.
My point being, the standard battery software clearly didn't read the extended battery's charge/discharge levels and probably needs to be recalibrated. Also, could it be that the standard batteries too are not being read correctly? I mean, we all may be thinking that the HD2 is a power hogger, which may not be the case.
I will be trying this experiment on the standard battery as well, and let all know on this.

do the battery calibration. completely charge and keep phone charging, open termimal emulator and type:
$su rm /data/system/batterystats.bin
reboot phone, after completly reboots remove the batterystats.bin again and then unplug phone and allow to die out. recharge and it should start reading correctly... 100% is aprox 4.2+, use battery indicator to read battery levels and info.

Hey!
You do realize, that the difference between the android system battery level and the battery level provided by the app "battery monitor" is due to different minimum voltage levels?
The minimum voltage level where the system would shut down is around 3.600 mV.
The minimum voltage level of "battery monitor" on the other hand is 3.200 mV by presettings. (actually you can set the minimum voltage manually)
As a result, "battery monitor" lets you discharge the battery more which results in a longer time you can keep the device running.
I would be careful though, cause undercharging is very bad vor lithium batteries, meaning a decrease of the battery lifetime.
Take care,
Ric

Hi!
At the time I wrote this, it was discharging and I was keeping an eye on the voltage. You're right, it completely discharged at around 3.66, and I set that as the minimum voltage.

Hello guys,
I have a problem with my battery this seems weird.
I don't have any battery drains but seems like the battery load when I'm not using it (screen off) like on the attached file. On the red bar I draw, you can notice it.
70-60% around and 40% around.
Anyone know why this happens?
Yes I've had that too after a reboot battery went from 70% to 75% not sure why, but is odd behaviour for li-ion batteries to do this. If it was a ni-cad or ni-mh I can understand this, its called recovery, after battery is unloaded it gains back voltage.

Maybe its because intensive use then after the phone rest and gain back some %

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?
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.
