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
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.

i did not see a topic about VERY slow charging and hot phone issue
first of all, typically for 10% it takes me 3 hours to fully charge my GS2, and it is warm but not hot
randomly it seems to get a bug that makes the phone charge VERY slow like 15% an hour or total 6 hours, and at the same time the phone is much hotter than normal charging
i had Android Assistant running and here is what is normal idle system spec:
CPU
system 2%
user 5%
idle 93%
ram
used 329MB
free 507MB
battery temp 97F
when the bug occurs i go to the stock task manager, close all apps, and clear ram memory, and here are the system specs after:
CPU
system 20%
user 40%
idle 40%
ram
used 460MB
free 377MB
battery temp 114F
i have not been able to isolate the process/app/bug anyone else?
I use Watchover (freely available on the market), which can give you a list of processes and the percentage of CPU they use. You can then identify the processes that eat the most of your CPU.
It's not a bug but a feature
The phone takes about 3 hours to charge when no apps are running.
More, if apps are running and even more if you are using the phone.
Totally normal for this type of phone/battery.
So if you want it to charge as quickly as possible make sure as little as possible is taking power....

but i stop all APPs in task manager and even clear my ram cache, so technically it should be like idle with nothing running
and yet it shows 60% CPU usage and 100MB or ram used somewhere, no idea where

this shows total usage between 100% charges of battery, so what might be the highest CPU % usage might not be what is currently stuck in a feedback loop
i want to see what process or app is "stuck" in a loop or on cycle that is causing the slow charging and hot phone bug
when i stop all apps in task manager and clear ram (which usually kills 19 processes in the background) i should be at 90%+ idle
i need an app that can show me a snapshot of what is running on demand and doesn't show what was running before but was stopped
What does the battery usage screen tell you? After trying to charge, unplug the phone and leave it for 30 minutes. Then open up the battery usage page and check which item is consuming battery power.
my phone was getting hot when i was using custom kernel and had overclocked
check your kernel first

OS Monitor will tell you in real time which process is using up CPU cycles. However, battery usage shows you which app/process is using up the battery, which is what is happening to your phone. It is using up battery charge as fast as the charger is able to charge it. So check out which app has the highest percentage battery usage. If it is Android OS, then you will have to use OS monitor to dig deeper to pin point which Android OS process (there are many) is causing this.
so i identified the problem!
it is HANDCENT SMS (MEDIUM) WIDGET even though i do not have that widget loaded on any of my home screens
this gets somehow bugged and starts to use 30-40% CPU real time, and even after i force-close the process it comes right back in a few seconds
i have uninstalled HANDCENT SMS and my idle is back to 90%
i bet if you have the SLOW CHARGING HOT PHONE bug it is because of this widely popular SMS app, i am going to try GO SMS instead
Hi. I searched the forum for this problem. Just got an GSII three days ago. Experienced this a problem few minutes ago. Started charging my phone when I got home. It was at 36% at 46deg c. Then I talked to my friend on the phone. Checked back 30 mins later and it was at 33% at 53 deg c. It was the hottest the phone was ever. I panicked and unplugged it and shut the phone down. Turned it on 5 mins later and I just plugged it now.
Is my unit faulty?

When I didn't rooted my phone, I also was experiencing overheating. Once I´ve rooted the phone and undervolted the phone and used kernel from Solarflare. Since then my phone didn´t overheat.
I wish we had a cpu temp reading as well as the battery temp one, I suppose the cpu usage will have to do, I think most overheating and slow charging is caused by power being used my the cpu as you charge the battery, some fault apps in conjunction with the heat of the battery produces when charging, really starts to heat things up.

I was just going to point this out as well. The same is true for a laptop. Recharging the laptop with the laptop power off will still generate some heat near the battery, but the moment you turn it on and start checking email, watching youtube, and doing all kinds of other stuff, core temps are going to be higher than usual as the battery charging heat adds on to it. So, I wouldn't be overly concerned with the overheating part just as long as it on a open surface like your desk and not wrapped up in a blanket on your bed.
With regards to the slow charging, that will directly be related to how much you use the phone, number of currently running apps, and number of background apps running (syncing, etc). I strongly suggest putting the display brightness level to lowest setting when at home while charging since this is the single largest consumer (50%) of battery power compared to anything else for me. If you do find that there are some less responsive apps stealing cpu cycles when it shouldn't, then I would consider uninstalling it altogether as it probably is also reducing your battery life during the day.
Thanks for the replies. I know the SII has a tendency to work up some heat and I'm just worried about damaging the internals. Does anyone know though what the maximum operating temperature is? So I could monitor my phone or turn it off when it reaches a certain temperature. I tried contacting Samsung about this but they didn't reply (their CS is bad in my country).

Yeah. I'd really like to know if it's okay that it gets hot a lot and at what temperature the internals get toasted. The manual says nothing about it.

I would say 46c when charging is way too hot, Im even finding 41c already above the expected charging temperatures.
I have noticed Kernels having a lot to do with strange battery drain and overheating. I flashed back to a stock Australian Carrier Firmware and as soon as my phone restarted it was getting hot. I could feel it burning through the back and front of the phone. I flashed another kernel and the problem went away.
I don't know if it's my imagination, but since the 2.4.6 update, my battery life has dropped a bit. By the time I get into my office from my morning commute, I'm anywhere in the 65-70% battery life after unplugging from a full charge. I haven't done anything new. I always unplug around 8:30 am when I head out, I do some light chatting with gf, browse some sites, check facebook (usually very briefly), and maybe sometimes do a little reading on my device. By the time I get into the office around 9:30 or 10 AM, I'm usually around the 80-85% area with battery.
Lately, doing the same thing, I'm seeing the aforementioned 65-70%.
Is anyone else experiencing decreased battery life since 2.3.6?
I'm on a Tmobile Nexus S, running stock 2.3.6 (no custom ROMs).
2.4.6 ? .... maybe 2.3.6 ... and yes, I also noticed a slight increase in power consuption after the upgrade. The stand-by is still great .. about 0.8 - 1% per hour.
Sorry, yes I meant 2.3.6.
Thanks for replying Ro_explorer. Is your increased power consumption significant? Seeing 65-70% when I'm used to seeing 80-85% as I get into my office, I find, is a large change. To be frank, the battery life of the Nexus S in general isn't so fantastic to begin with... this hit makes it worse.
Anyone else?
I used to get home with about 40-50% after a whole "normal day" (unplugged at 8AM, and getting back home at ~8PM) .. now (with the same average usage) I'm getting home with ~30-40% ... that why I said "slight increase" ...
Not your imagination, I too have noticed this. I hope the next update, will fix this - as I used to get pretty good battery life (even with over 250 apps).
When I recently updated to the 2.3.6, it caused a bug of continuous reboot (every 1-3 minutes), so I had to do a hard reset - now it works fine, but I only have added back about 15 apps - and the battery life sux!
Downgrade OS' it will be ok.
This is so weird. Why is the battery life worse?

You want bad battery life? Try an Evo 4g with a Sense rom. I averaged about 6hrs using a 1500mAh battery, in stock form.
The nexus is pretty light on power consumption, if you ask me. I average 15hrs on the stock 2.3.7 rom/kernel combo, with stock battery.

I'm on 2.3.6 and need to charge every two days. I text a lot and do light gaming. I'm typing this from my phone. Maybe you could drain the battery and wipe battery stats? I'm not even at 50% yet and I charged yesterday.

i noticed a decent increase in battery life going to 2.3.7 and thought that previously the battery life had been fairly poor :\
I am non rooted, and get around 20 hrs on light to moderate use. Again. Stock, non rooted.
How do I recalibrate my battery? I wonder if it could be that...
There are many was to recalibrate. Some involve wiping batt stats, some plugging and unplugging phone several times after charge.
I have always found that using the battery almost all the way down, but not past 5%, and then full recharge conditions it very well.
Oh I've been here to solve the problem
"Why last 2 weeks my Nexus s drain battery so fast ? or I have to calibrate it"
Thank for your notice about update OS to 2.3.6.
I think that's a root cause for me too.
1. Could I rollback to 2.3.4 ,how?
2. Does battery calibration is useful for this case , how?( someone suggest to calibrate when flashing new rom )

Whenever switching roms, kernels, or batteries, i always perform the following :
1. Charge to a true 100% (Battery Monitor Widget will register +0 to +2 mA)
2. Wipe battery stats using recovery (Amon RA has this option for the Evo, not sure about cwm), Battery Monitor Widget, or a dedicated app.
3. Discharge battery to 0% with normal usage. When the phone shuts down, I pull and re-install the battery and power back up (it will shutdown again very quickly).
4. Recharge battery and be on my merry way.

I found one workaround solution for this issue on
ww.google.com/support/forum/p/Google+Mobile/thread?tid=1684c50cea15282a&hl=en&fid=1684c50cea15282a0004af022e5ed212
Sproogle77 's solution
Problem solved. Using the OS Monitor app, I found that the main culprit was Google Services - the Contacts sync specifically. Even though I had this disabled (only Gmail was being allowed to sync) it was constantly working, apparently trying to fix a location. The message log showed that it was generating continuous debug messages, all about locations - around 10 of these every second.
I have solved the problem by disabling 'Use wireless networks' under the Locations & Security settings.'Use GPS satellites' is still running. This immediately dropped my CPU usage - which had been running around 30 to 40% even when otherwise idle, to around 10%. Google contacts sync is now using 0% of the CPU. The difference in battery life was pretty much immediate and is now back to what it was before - the change in the slope on the battery usage graph is remarkable!
This doesn't really seem like a solution to me, and I don't know whether other aspects of my functionality are being affected, but at least my phone is properly useable again.
I'm testing for 1 day and I think that's working for me.

One reason is that the new version of the stock kernel removed a speed stepping, so it'll power to higher levels faster, thus using more battery.

That actually isn't the problem. I'm using netarchy's kernel and still get this problem.
My battery life dropped from 16 hours --> 6 hours. the slope on my battery usage life is horrible the system is also awake almost constantly even when I'm not touching it / getting no messages.
I will try the fix suggested on the google support forum and see if that does the trick. sloppy update.
Hi guys,
I got a 32 gig grouper off Ebay in July 2015. From the get go, I was impressed with the battery life, and it got even better when I went the custom rom route. My main use case is streaming movies or TV in the evening for a few hours, and otherwise leaving it in standby/airplane mode to conserve battery life until the next viewing. Typically overnight, the battery sips power -- maybe 2-3% lost in 7-8 hours.
Over the past month, though, I've seen a considerable dip in the standby/airplane mode time in particular. Now, overnight I seem to lose 10-15%. I realize batteries have a lifespan, but I figured I'd see a more gradual drop?
I tend to only have 4-5 streaming apps on the tablet at a time. Currently I'm running CM11 stable, but I observe this standby battery drop in all roms -- I've gone as far back as 4.1.2 (stock + unrooted) and all the way up to CM13 unofficial. I used better battery stats/GSAM but never really caught any wakelocks that would account for that much power lost.
At a loss for what to try next. I can capture screencaps if it helps, but they never really told me anything (perhaps someone else would get more info from them.) Any help is appreciated!
Also, my on screen time feels about the same. I've drained the battery a few times with some streamed video, and I get around 4-6 hours. It's the standby time that has dropped off considerably.

Get Kernel Aduitor or a CPU managament program and see if your tablet is going into deep sleep or if it's still at another clock frequency or if a program is keeping it up.
Thanks for the reply!
My N7 is in deep sleep about 80% of the time on a typical charge, the other 20% being used for on-screen usage (video streaming and browsing typically). It's maddening -- I now lose 15-20% on standby/airplane mode overnight. I don't see any flags in better battery stats or GSAM battery monitor. Most apps are greenified, too, and location services/other potential draining factors are disabled.
Is it just a bad battery?
