So this phone has had a really good battery for me throughout its lifetime. I've even tried to maintain it between 20 and 80% charge most of the time. So I believe I've treated it quite well.
I'm using AccuBattery to track the behaviour of the battery. to notify me of the charge level when I should unplug it (I can automate this in my smart home). A good discharge rate for when the screen is off used to be around 0.5%/hour, but recently the phone has been wasting 1-2%/hour consistenly when not in use.
I've noticed no unusual wakelocks, no apps drawing an unusual amount of energy, I've tried restarting the phone of course, and I can't seem to find a software cause to it.
AccuBattery reports my current battery health at 84%. My conclusion so far is that the battery has aged a little and can no longer sustain its capacity as well as it used to when the screen is off. Also, the discharge rate with the screen on used to be around 10% an hour, and now it's closer to 15%.
Any thoughts and suggestions?
Replace it before it fails.
When a Li falls below 80% of its original capacity it has reached the end of its service life.
A degraded Li is more likely to fail which can seriously damage the phone.
Thank you for the answer, but I believe that's a bit drastic.
The battery has barely started to noticeably age. There are phones around me 3-4 years old where no one would think to replace the battery yet, since the behaviour is not erratic or the capacity hasn't gone considerably, or to an extent that decreases the phone's usability.
Another piece of data that I forgot to mention: AccuBattery shows "deep sleep" time as around 60% of time when the screen is off, while that used to be 80-90%. I think this behaviour started with MIUI 12 on this phone.
Still trying to figure this out. I suppose the higher battery consumption per hour when not in use is directly caused by the lower deep sleep time.

Cloud apps doing backup are prime offenders.
Trashware like FB, WhatsApp etc.
Try in safe mode overnight to narrow it down.
I've just deleted/disabled Lite Messenger and FB Services, I only need FB Lite. Set battery optimization for a few more suspicious apps to not allow them to run in background.
Whatsapp is a useful app for me, and it does its local backup every night at exactly 2 am. I'm fine with that.
But I've got that low deep sleep time both during the day and night.
Next thing I'll try safe mode. But will it allow me to run AccuBattery in order to track the battery draw? Or I'll have to keep track myself of the percentage before going to sleep and then in the morning.
Lol, Accubattery is a 3rd party app...

I've had my battery replaced, I've wiped my phone from ROMs, and I've used aggressive SetCPU profiles...
What is annoying though is setCPU recently updated and I decided to see how my phone ran without it.. battery life is horrific with a simple UV kernel.. Why is this?
I mean I take my phone off the charger at 11am and by 10pm its less than 15% remaining. I now have a second battery from HTC after a warranty replacement but I saw very little change. I have a task manager that auto kills everything now which helps but it is annoying since I lost my car charger my phone is discharging all day.
Is this normal and I'm just freaking out or do I have a real problem?
Running Kang-o-rama ROM with ~20 apps
I know 3 things about the N1 battery:
1) it took a couple of weeks for my battery life to max. Lithium batteries need a break-in period. They have no memory, and the recommended approach of not using the phone until it's full charged is bunk. Just use it normally and it will work as it should.
2) Switching between 2G and 3G constantly murders the battery, 4 hours and you're dead. If you're going to be in an area like that for a while, force it to one or the other.
3) Watch your apps. If your phone is acting even slightly sluggish it's CPU is maxed which is killing your battery. Slowly swipe between homescreen pages, it should be silky smooth without any stutter. Try and track down which one it is and either install/reinstall (which fixed an issue with Better Keyboard for me) or completely uninstall if you can't fix it. Check for apps that ping the network too often, or ones that start up on their own.
I will add that the built-in 2.1 battery usage tracker is not 100% accurate. In my Better Keyboard example, Android said it was the screen using all the juice, not the app. Might have to do with video graphics drivers, I really don't know. Point is, after uninstall/reinstall my screen used 55% of my battery instead of 75%, so don't trust it.

Are you kidding? You're running your N1 for nearly 12hours and you STILL have 15% juice left?!?
Search the forums, 12hrs and still having juice left would be considered excellent to many.
...Then again, you haven't mentioned what your usage is like. If we were talking about your phone being in sleep mode for most of those 12hrs with just an occasional call or 2 that only lasted very briefly...Then that's a different story.
Have a look at Juicedefender, it will limit your internet access to 1Min on every 15Mins when the phone is asleep/screen is off. Does wonders for battery life
ok so my phone has been off the charger for ;
5h 23m 17s
I am at 56% battery.
What concerns me is that my display usage is at 56% of my battery usage with just 22m 27s of usage.
now if I do the math that means the display has used 25.76% of a full charge in just over 20 mins of use.
This seems absurd especially for what is supposedly a more efficient display. Do these numbers seem on par or do I have a faulty battery/device?
Has it been conditioned? I know conditioning does nothing to the battery itself, but it does cause the percentages to reflect more accurately.
Also, was it fully charged 5 hours ago when you took it off the charger? If not these numbers are meaningless.
I suggest comparing multiple charge cycles, not one strange instance.

No, I have not conditioned, the phone.
Yes it is coming off of a full charge.
This is the first day I have taken it off the charger for the full day. I have had it connected to computers via USB to install music apps and get it rooted since I got it so I do not have any other cycles to compare it to accurately.
To be honest these batts do not need conditioning, they have no memory effect.
OP Display is nearly always the most. Unless you make long calls (which could make calls the highest) or never use the phone (stand by would be the highest)...
I would be far more concerned if an app or other device function was at the top of the list other than display.
I had initial concerns about the battery when I got this phone. Now that I have settled into a normal usage pattern (few videos, email, web surfing, Facebook, etc.) I get a full day (7am-10pm) out of a charge.
Just use it as you normally would and don't worry too much about the numbers. See how long it lasts and then adjust as needed. You can disable something that you don't need at that particular moment and make a big difference (like turning off Auto-Sync when you don't need to be constantly updated of your friends Facebook status or turning off 3G when you aren't going to be surfing).

The fact that the display was on top is not what is concerning me it is the percentage of the full charge it used that has me worried.
In the total time off the charger at the time of these stats I used 46% of the battery. 56% of the 46% was for the display. That means that in 22 mins my display ate 25% of my full battery, which would equal out to my phone being dead with 1h 20m of screen time assuming no other resource used the battery.
Hi,
I recently flashed my G2 to the leaked T-Mobile gingerbread release: so it's not rooted or anything like that. I'm not using it any differently to how I was before.
The upgrade went very smoothly. However, the battery seems to be draining a lot more quickly than prior to the upgrade, and Android's battery usage app points a very damning finger at the display: currently it's showing 67% usage, and pretty consistently shows a high usage most of the day.
Before, I could consistently run the phone for the whole day and charge overnight, but now I'm finding that I have to charge it a bit during the day too in order for it to make it to the night.
I'm pretty sure that I'm not using it any more than usual, and I pretty much always have brightness set to 20%.
So my question is, what could be causing this? Could something be using the screen when it's not supposed to be even though it's not showing anything? Could it be a battery calibration issue? Maybe the power usage app in gingerbread calculates what it attributes power consumption to differently to froyo (though that wouldn't explain the overall reduction in life). What, if anything, could I do to try and track this down further?
Any suggestions would be appreciated!
Some things I should add.
I really haven't changed my behaviour regarding how I use things like wifi, bluetooth and gps. In fact, so far I actually have one fewer gmail account set up on it that before the upgrade, so sync should be doing less work. The apps I'm using are all about the same.
When I said I could use it for the day, I mean it would often end the day with more than 50% battery left. On some days I'd get it down really low, but that would be due to obvious extra usage, which isn't the case here. Occasionally I'd let it die completely. I always charge it fully overnight.
Finally, here are the other top items in my power consumption list at the moment:
Display: 67%
Maps: 8%
Cell standby: 7%
Phone idle: 5%
I seem to remember that before the upgrade, Cell standby and Phone idle were usually the top users of power.
no problem
Sorry, but I don't see any problem. Maybe its just placebo. This is the same on every android based phone. I Had HD2 and had 2 NAND androids till now and the battery stats were showing also display use 60% and then after new NAND version - gingerbread they were up to 80%+ but the battery was better than ever before.
Let me explain it to you. The display should consume most of the battery if you have 3.7 inch display and more. Maybe some navigation and 3G is the biggest sucker like the display but with normal use the Display. And if your display consumes lets say 75% of battery over when you are at 1% battery then it means it sucked 3/4 of your battery and just 25% other things did like phone idle and cell.
If it was before and your display consumed like 40% or less that meant that the other things like cell standby, phone idle consumed more power so it wasnt battery efficient. So its more battery efficient. Maybe you just have much more awake time than you did before. The awake time - sucks the hell of your phone(some apps warn you taht your phone wont turn to the sleep, which means your processor is still working hard which means your battery will deplete completely in a short time)
I experienced this also that my phone lasted only 6 hours or so and before it could wen to all day . Then I deleted some apps which were causing it and my battery was perfect.
and last advice. try to charge your phone via USB, I dont really know why it is caused but it will last longer , but on the other hand you will have to charge it longer. But if you go somewhere where the extra juice is needed then its nice.
With these steps my HD2 with old battery (about 1000mah left on 100%) went through 2 days of medium USE and about 5 days of just receiving calls and messages) so I dont know anyone else who could say that !

hope I helped you. GL a HF
If you can stand it, turn the brightness as low as you can handle . EDIT, you're already doing that....hmm
Not sure why gingerbread is giving you problems, personally I find it slightly better with battery than froyo.
Sent from my T-mobile G2
Hmmm... placebo. By that, I presume you mean that since Display is ranking higher in the list now, that's making me think more battery is being used before. I suppose it's possible, but really it's more to do with how often I've been reaching that "I should charge" point, which for me is a function of battery level and time. If I get to 50% before lunch time, I think "I should charge". But getting to 15% just before bed I don't. What I've noticed is that since the upgrade I've reached the "I should charge" point every day.
I'm just very surprised by how the proportions in the battery usage list have changed, while a the same time the phone's battery usage seems to have increased, despite the fact that Gingerbread's battery usage is supposed to be improved.
One other thing that came to mind: perhaps Gingerbread's battery usage is just more accurate than Froyo's? It always seemed to me that the battery level used to work a lot like a car's fuel gauge: it would stick at 100% for a long time and then would drain. It was as though "full" as a concept understood by Android was a range rather than a limit, and so as a result the phone appears to drain more quickly, but it's actually just showing a more accurate battery level over time. Just a theory.
So last night I allowed the phone to completely die. This morning I switched on and immediately checked battery usage: display showing 99%, which is exactly what I'd expect. So I'll see how it goes now that Gingerbread has experienced battery exhaustion.
Personally, if I was upgrading from Froyo to Gingerbread, I'd prefer to start from scratch rather than doing an "in-place upgrade". I'd worry that maybe there are some leftover settings or files from Froyo that could cause unintended consequences. Consider backing up as much data/apps as you can (it's more difficult if you don't have root), charging the battery up to 100%, doing a factory reset, and then restoring and reinstalling everything back. Doing this will also reset Android's battery stats file, so you may find your battery levels maybe inaccurate while it's relearning the right levels for a few days.
Alternatively, if you don't fancy a factory reset just yet, you could try monitoring your power use with a widget like CurrentWidget which looks that the current draw rather than percentages. Also consider installing Watchdog Lite which might be able to help you identify if there are any processes using excessive CPU cycles.
EDIT: Just realised that if you flashed a leaked version, the install would probably have wiped everything anyway, so you can probably disregard the first paragraph.
Like the others have said, I think the screen usage being higher in 2.3 has more to do with the reduced usage of other apps and not the screen using more battery than in 2.2.
Think about it, most of the high battery usage items (web browsing, etc) also keep the screen on at the same time.
Yes, that's probably mostly because other things are using less power. I also suspect that maybe Gingerbread's battery usage app is calculating display usage differently: I just checked it on someone else's G2 (still running Froyo) and Display was way down the list. It dominates mine, even though I haven't used it that much today.
Today's power consumption has been a lot better. It's down to 39% now after 12.5 hours on battery, with 59% of that being attributed to Display. So that's not bad at all really.
Thanks for the tips on the monitoring apps. I'm already using System Panel (which only seems to care about apps and not hardware so much), but it's always worth checking out alternatives.
Couldn't it be due to you being in areas with bad connection?
I noticed that my G2 is down tot 30% after a few hours at school in bad reception+bad wifi areas. When I'm home the whole day my G2 is still at 60% at 10pm.

When my phone is fully charged or has 70 or 60% remaining battery it seems to drain as normal, around 2-5% over a 10 hour or so period...
However, I've noticed once the battery decreases below 50% it drains FAST, why?
Anyone else noticed this? Test it for yourselves, monitor the TIME it takes to decrease from 100 to 50% and then from 50% to 0.
Yesterday I forgot my phone in the car whilst going to work. It was turned on however it was sitting all day in the car.
Once I returned from work I was shocked to find the phone would not turn on.
At first I thought there was a problem or some kind of fault. Once I plugged in the charger it started to charge, the battery cut and the phone automatically turned off!
I remember the phone had around 48% battery remaining, no wifi or 3g or data turned on. It was simply idling...
So the question is HOW can the battery drain from 48% to 0% over a 10 hour period without being used???
Should my battery of been ANYTHING over 50% it would only lose a few percent...
Same thing for me. (Samsung Galaxy Note N7000 - stock Android 2.3.6)
Battery slowly decreases from 100% to ~50% and then ~2x faster.
I charged the note on my computer and then switched to the charger (at ~60% of charge).
I'm no expert of battery charging etc. but just remembered my iPhone 3GS discharging faster when charged on the computer than with the charger.
If it's the same for the note, some cells could discharge faster because charged on the computer.
Can someone confirm this (or not) ?
How did you charge your phone ?

Same thing happnd with me, and charging my phone thru electric charger..
So it seems this behaviour happens to several other Note users, why?
It's a problem knowing that having around 50% left in your battery will struggle to make it through the day with little to no use...
Have you people set the wifi to turn of while the screen is off? This is unnoticeable in the daily use, but increase the batterytime massively. The setting for this is hidden, you have to push menubutton while in the wifi-settings.
Here I thought I was only imagining things about the battery life dropping faster once it has reached 49% or less.

Haha, nice to know I'm not the ONLY one facing this bug...
I can only hope Ice Cream Sandwich solves this battery drain issue.
Hmm, i think i have the same problem, but i'm not sure. Will get back to this thread when i've investigated a little bit.
This may be a typical samsung issue.
I remember when i had the spica , the battery percentage lining in kernel was totally wrong. I think its done on purpose so you would feel like you have more battery life. 75 % of the battery drains slow. And the rest 25 super fast. Can be fixed within kernel.

I believe its just a placebo effect. Battery usage always depends on so many factors its a pain to even consider starting looking for the issue.
Being on stock KK5 not rooted, i cannot report the same. I only see "fast battery drain" at the last 4-5%. If you feel its an issue, could you post the firmware version you are on and the battery stats graph just for reference?
Placebo or not its something I can definitely feel on my Galaxy Note.

When you get the chance, could you post the battery stats graph please? what we should see is a (lets say) 30 degrees angle and at about halfway it gets steeper.
I know its quite hard to demonstrate the issue, but if you lets say use wifi to browse the first 50% in text only sites and then visit youtube for the last 50%, it won't help the test.
A nice way to test it would be to charge it to 100%, then load up a long movie and repeat playing it till the battery is 2-3%. Then post the results.

When the Wifi is disconnected, the 3G scanning will get on. Isn't that defeating the purpose?

Hey there!
I would suggest to load the battery 100%, plug it out, go into recovery and wipe battery stats.
I have to admit that I don´t know exactly what this workaround does, but I read about it in another forum...and it worked for me, my battery status is much more accurate now!

I'm back. I've had the Diagnosis app running for the past hour, and i got some interesting results.
---Wiping battery stats does not help---, a full charge automatically causes battery stats reset.
I full charged mine with the electric charger after fully discharging it without turning it on.
This time i didn't notice any change in discharge speed between 100%-50% and 50%-0%.
Last time I charged the phone it was not fully discharged. Charged it from 30% to 50% then 50% to 75% on the computer, and 75% to 100% using electric charger.
It's just a supposition, but maybe doing several partial charges while using the phone makes the battery % information inaccurate (wrong battery stats?).
[Edit]In this case, wiping battery stats should show accurate battery %. [/Edit]
I had a similar problem, and I think it is to do with some incorrect scaling or measurement.
I was down to 28%, and it seemed to be draining fast even though I was not using it. I rebooted (I love how quick that is after my Arc was so slow). On restart it was at 17% ! The usage graph just did an instant drop.
I also had another occasion where it remained at 100% for 2 1/5 hours of use.
I assume some calibration issues caused the meter to read the battery wrong. I am turning off on the w/e overnight (when I do not need the alarm) to see if a slow (180 mA) charge while off will help. I may even get a decent alarm clock so I can turn the phone off at nights and charge. I spend too much time in the morning checking my email and reading news!
What is more consistent on mine is that when the battery drops to 9% or less the loss is like 1% per ~10-15% and this is with wifi/3g off, phone locked.
I'm back again. I've had some serious battery drain the last couple of days, but i noticed that Auto Sync was enabled. Once i deactivated it it got much better. Pulled the phone from the charger 9 hours ago and i'm at 90% battery left. I've sent some SMS, a few calls and that's about it, but it doesn't drain while it's in standby now, so i'm happy with it.

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

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.
