Battery drain <90 and below.. - Galaxy Note II Q&A, Help & Troubleshooting

Hey guys ive done a similar thread on this a while back but this is a bit different now the issue here is when my phone from 100% all the way to 90 % battery is awesome like so damn good. but when it hits 89% it starts draining quite quick the main drainage is when i put the phone in sleep mode it drains. like i had my phone at 85 % left it for exactly 5 minutes and it dropped to 84%. Ive tried every rom/ kernel out there..nothing has helped or changed. I took it to the warranty they said its a software problem and that didnt fix anything. i have BBS and Kernel wakelock since boot is "wlan_rx_wake" maxing out at 2.6 % the others are just power manager service , etc. Partial wakelock since boot is AudioOut_2 stricking at a 17.8% max. And all the others are NetworkLocationLocator. Currently on Pheonix Rom (Debloated ALOT!!,awesome rom) and Note2core since Pearseus gave me lag issues.

Most battery issues are caused by:
1. antenna transmitting
2. screen time
3. processor load
Troubleshooting should start from the simplest things (Before you replace a motherboard/power-supply, make sure the computer is plugged into the socket, etc). Look at apps that use the network (Google Now, Google Local, Google Maps, Google Mail, Google Calendar, Google Contacts, Google Photos, Picasa, Instant Upload, Exchange ActiveSync, Samsung Backup, Weather Widget, Weather & News and whatever app you decide to install, ie: Facebook, Twitter, Reddit, Viber, Skype, WhatsApp, etc) and make sure you disable or at least change the app's setting to update less frequently.
Make sure you use automatic brightness and feel free to lower the bar around 50% when full screen brightness is not really required.
Make sure you don't have some app constantly running in the background (You can see this from the Battery menu, the phone shouldn't be 'Awake' most of the time when the screen is off).
I manage to get ~15-20 hours out of one charge, with 4-6 screen hours and all of the apps I mentioned above (with proper sync settings, of course).

Thats cool but i really wanna know why from 100 to 90 battery is awesome but then it start sucking up

Do I have wake locks problems? =(

no those look fine.
a wake lock issue will show around 90% of uptime as awake.
your looking around 11%.
The reason its ace from 100 to 90 percent is that to hit 100% you have to over volt a lithium based battery. this is why most chargers switch to trickle around 90%.
so it confuses the battery monitor as its in a way (as the battery level indicator uses voltage to indicate charge) more than 100%
the battery is a 3.8v battery, but between 90 and 100 percent it is at around 4.6v and dropping so until it hits below 3.8v (100%) it drops very slowly.

Now that i turned off Google Now and ticked off all 3 settings under GPS, I rarely lose a percentage when the screen is off. [I lose 1% overnight] With that said, I feel the total opposite. I feel like phone gets stronger as the percentage goes down. Try doing what I did and let us know what happens.

But why does mine drain so quick..people get like 20 minutes of on screen time per 1 % i get like 3 minutes if im lucky..

Lost 10% overnight..,i keep most of my stuff really off but it still drains..
bluetooth off
nfc off
GPS off
My google now is on however i dont use it that much..does that really effect your battery ?

Yeah Aus, try turning Google Now off. I personally think it's extremely overated. It keeps track of your location so it will "try" to use gps even if it's turned off. I think just by the program waking the device"trying" to use the gps is wasting precious battery. Let me know how that goes.
ps - obviously I dont have bt and nfc on at all times because I have no use for them myself. but my wifi and 3 emails are constantly on and syncing 24/7
ps 2- I used to lose 10% overnight just like you but I had Google Now and all 3 GPS settings ticked on.

I'm surprised no one has mentioned it yet:
It's a battery gauge. It doesn't actually show 100% of the time the correct %. It could be not calibrated correctly (shouldn't need to, either). I actually spend a lot of time from 100-80%. Then it drops rather quickly! I hardly ever spend any time below 60%, so I'm sure it's just my battery reporting what it THINKS is the correct battery life %.

Battery Consumption Questions

Hi guys,
I have to say, compared to my HTC Hero and Modaco 3.2 rom, the battery life on the Desire seems pretty poor to say the least.
Do you have any tips? I know there are mixed views on task killers but whats the general consensus? Seems like every app that gets opened, seems to stay open forever or atleast open in the background on this thing. Is that good or bad?
Does the Gmail app which is push based I believe consume less battery than say the HTC Mail app used to sync about every half an hour?
Have you discovered any particular HTC apps that drain more battery than normal?
I've already disabled Facebook and Friendstream completely, use seperate apps for those.
It just feels like the battery eats away even when the phone is just sat there with the screen off, sure I have 3G on but Twicca is the only thing set to update every half an hour in the background and the Gmail app on push no doubt.
Any tips?
pretty sure if u slightly decrease the brightness of the screen and stop all data connections unless you want to run them will help the battery life
disable live wallpapers
disable auto updates
disable 3G (just for the sake of trying)
decrease the brightness or make it auto (dont put it to the max)
put plain black wallpaper as background (trust me it consumes 40% less than the colored wallpaper, again, do it just for the sake of trying)
try this for one day and see if you get anything different
I have the brightness set really low, don't use live wallpapers.
I would disable 3G but that kind of defeats the purpose of having twitter updates and stuff, one of the main features of the phone.
Just checked and Twicca is only set to update once an hour, this is really weird.

I saw somewhere that you can see what app is draining your battery life in the notification bar, just open the notifications bar and go to battery, and see if you find anything related there
I have the phone for 3 days and I'm still in the stage where I play with it all the time.
Day 1: fully charged at 1PM, used the phone pretty much non-stop till 10PM and finally plugged it in with 3% left;
Day 2: unplugged the phone at 8AM, had it in stand-by for couple hours, then used it non-stop for 2 hours, then 4 more hours of stand-by, then it 2 hours continous use. The rest was more or less stand-by. Plugged it in at 10PM with around 10% left.
Day3: used it quite a bit on and off during the day, still have 34% left.
I don't do any fancy power saving, though I don't like apps updating themselves, except for mail. However, I use WiFi when I can and I listen to podcasts whenever I walk/drive somewhere.
It's a bit too early to draw conclusions, but at this point I'd say that Desire's battery life is much better than G1's (I had 1600 mAh battery).
Of course it all depends on particular use case. Also, maybe the network is spotty in your area - that might drain a lot of battery.

Android System eating the battery

Hey all, I don't know if anyone has even noticed on their Evo's but on mine, the Android system usually eats most of the battery. I noticed there is a ton of processes under Android system that are running compared to like five on my Hero. I've never seen the core system processes take up more than maybe 15% of the battery, but right now, I'm at like 41% with 16m 6s of CPU total and 47s of CPU foreground. If anyone knows why this is or a way to fix it, please let me know. I'm on the first MR update. I've been able to get a lot of battery stuff figured out, if I can get the system to calm down, then I should be able to get even better battery life than my Hero.
I'm seeing the same thing, android system is at 96% battery use after letting the phone sit overnight. Never saw that on my nexus, this is strange.
Could be related to the fact that everything is syncing up, I just activated last night too.

Yeah, the system seems to have calmed down a bit today, though I also have the OC widget running to keep the processor lower during sleep. I'm guessing its helping, but I'm not sure if there is something else to get it down. I almost never even saw the System show up in usage on my Hero, now its one of the top contributers. I got used to having custom roms on the Hero, but so far all I need on the Evo is unrevoked. I know a lot of people around here don't like it, but I found I only needed a couple of apps that require root and so far love it. That OC widget really comes in handy.
maybe i can clear things up a little bit for you guys...what you see in the battery use section is distributed across 100% of the time since you last had it plugged in. if you notice all the percentage numbers add up to 100%.
if you plug your phone in and turn it on and off on you will see that android system is probably around the 90's thats because android system has used 90+ percent of the phone since you plugged it in....over time that number will lower, becuase other things will start using the battery power... what you see is a percentage based on time. not based on whats actually working RIGHT THEN AND THERE do you guys understand?
I too am having that problem and at 15% battery life warning - it still shows my Android system @ 40-44% usage after 8hrs of work.
I mostly text message all day long due to work - make phone calls and recieve calls from work every hour. GPS on for no more than 15min all day long to get direction when my keymap book doesnt help.
4g off, bluetooth off, background data 15 min only (gps) than off, gps off when not in use, mobile network (3g) off when not in use.
I would have figured my screen being on would have drained my battery life since I check text message every 10-15mins for 8hrs...
So went to work at 9am, 100% life
got off work 6pm, 25% life
I've done all the tricks, cdma only, force stopped a bunch of apps, goggle talk off, sync off, making sure maps/gps has been closed (forced or not)
still disappointed with battery life.

My crappy AT&T Razr lasts me 2-3days with text message + call + 1.5hr of playing Bejeweled a day

check your hardware version there is a thread about different types of evos and it seems like everyone who has the hardware revision 0001 has really bad battery life. i would exchange your device.
Yes we know, Freelancerx, or at least I do. But after over 8 hours and the system is still using more of the battery than anything else is a little disturbing. Never seen that on any other device. I have Hardware 0002.
I have this same issue with hardware version 0002. I run Fresh 1.0.1, i use Netarchy-toastmod kernal, have latest radio. I have also tried Damage Control (did get slightly better battery life out of DC but not amazingly different)
after 7 hrs since unplugged my andriod system is at 39%, cell standby 28% phone idle 20% display 9%.
i dont have bluetooth, wifi or 4g on. I use juicedefender+ultimate to turn off apn when screen is not on. I use set CPU to underclock when i am unplugged and go down to 128 when screen off and i am Stilll lucky if i make it all day with moderate usage.
Every day it is the same andrioid system is around 40% of the usage for the time it was unpluged.
the following is listed under included packages (not sure if this shows the same for everyone or if it shows what packages are running)
BRCMBluetoothService - Bluetooth is not on so if it shows packages running this may be an issue
Sync Feeds - I have all android syncs off and mail at 6 hours
settings storage
Rosie Utility
Acounts & syync
Account and sync settings
settings
HTC Widget Download Manager
Network Location
Setup
HTC Checkin service
Checkin serivce
VPN services
Android system
Wonder if there is something to the android system on these (ie something not turning off that should) or if we are all just crazy and happen to get the same results.
I had a hardware 0002 model and often experienced the same thing with high system % usage.
My phone was replaced, due to a screen issue, and now I have the 0003 model and seems system % is much lower so far.
I haven't installed any system update yet, so I am on the first original release rom (not rooted yet).
Going to be testing it for a few days before I update and root, so I can make a fair comparison between the original and current oem's.

I think everyone here understands this. the question i think we are trying to figure out is why with similar usage and configurations some people get 40-60% android systems usage while others get 10% over the same period of time.
Android system is way too high.

Yes but if it is configured in an optimal way then android system is always beneath cell standby and phone idle.
For example, today after 15h 28m 23s since unplugged I have...
Cell stanby 38%
Phone idle 37%
Android System.....12%
That is with background processing with auto syncing every hour or so.

How can I check what ate my battery in the past 3 hours?

My battery life has been great with the current set-up, but in the past 3 hours something screwy happened. I basically went to a function and I turned off BT, Wi-Fi, Mobile Data and GPS. Only thing on was the cellular network and I swear I didn't use it for more than 5 minutes. The battery was at 98% before leaving, now in those 3 hours it came down to 50%. What the crap? The only thing I did was to play Super KO Boxing 2 before leaving for about 5 minutes(It still shows its battery usage as 20% but no option to force close, so I am presuming it isn't running). I did open Maps and HTC Locations(Sense 2.0) for 2 minutes but I closed it because I didn't need it anymore, I also disabled GPS right after that. Now after all of this(game and gps stuff) I had 98% battery. Yet 48% of my battery went into thin air just like that, my battery use is Display: ~40%, SKOB : ~20%, Voice calls: ~15%(About 3 minutes), Cell standby ~2%, Wi-Fi ~4-5% or something like that. These are from memory since I turned it off and kept it for charging.
Any ideas what screwed things up?
Edit: Just noticed you are already familiar with the battery %age lcations.
From what you describe, it sounds as though there were some apps running in the background, slowly om nom nom'ing your battery. I daresay there are a few apps on the Android Market and elsewhere that can tell you what services are running at any given time, so you could get one of those.
If you're after ensuring maximum battery life, however, your best bet is to shut down the Desire, then fire it up again. That way, you can be sure there are no background services to drain charge. Couple that with lowering the screen brightness and display idle timeout (not to mention upgrading to Android 2.2), you should be able to go at least a couple of days on standby.
Sounds like one of your apps is keeping your device awake. I'd suggest getting app monitor like SystemPanel and run the monitoring for a few hours to see which app is consuming the battery.
And get WatchDog. It will notify you if there's any app that use the CPU more than 20%. You can set the percentage yourself btw.
All right, I'll be formatting the phone and flashing the RCMixHD v8 ROM(Was using v7) and then see what happens. i can bet my life that it was either HTC Locations or Google Maps screwing things up.

Why is batterylife worse on Froyo?

I'm getting 4-5x idle consumption on latest JPA. Hope this is still not final..
I see that next version of Android is already trying to discredit previous one. Don't be afraid, gingerbread, we will update to you anyway =))
On a more serious role - I see approximately the same battery.
Re-calibrate your battery.
A bit worse on my end on IDLE, but same on usage, close to 8hrs of battery life watching a 720p movie.

Whats a good method of recalibrating it aside from deleting the battery stats..
Speaking of battery stats, a lot of people misunderstand this as the file that keeps the current charge of the battery.
my standby time of the battery is great. No drop in battery after a full nite of sleep.
however, surfing net on data really eats a lot, 1% every 2 or 3 times.. really fast

Maybe you just can't understand well the charts.
for example: Music Player 25%, it doesn't mean music player consumed 25% battery; This means that when music player was worked, then battery consumed was 25% - what did consume it? - The music player + display + some refresh + etc...
Yeah, I know a little bit strange logic for "Windows taskmanager" browser kids; but this technic is general in mobil IT (maybe Google should hide this feat, bcoz lot of users are confused; and ask again and again and again and again and again...)

I dont even think he is basing it on the battery chart usage, I dont think anyone does.. we are just looking at the battery indicator. If we idle for 8hrs we epxect no more than 2% battery drop.
I get 20% battery drop in froyo for 8 hours during the night without even switching the phone screen on once!
Maybe because of all of the services I have?
I have the following real time services:
1. google stuff
2. exchange (touchdown)
3. Tango
4. whatsapp
5. Chrome to phone
6. SMS Backup+ (backs up SMSs as soon as they arrive)
In addition to that, I have two email addresses configured in the stock email app with 1 hours pull time, and in "accounts and sync" I have facebook and twitter put as sync once a day.
I have a bluetooth headset connected all the time and receiving calls though it, I make and receive almost 1 hour of call, probably 5 SMSs, WiFi is on all the time, and the display is set to auto.
It is also worth mentioning that I have the JPA, OCLF and the 341MB ram kernel (250Hz) with the enhanced GT TWLauncher, no live wall paper, no auto syncing widgets.
My battery lasts almost 8 hours until it is flat, in which I have another charger at work, that a good 2 hours charge keeps me going until sleep time, where it is flat again, and then I put it to charge all night long.
If anyone is having my same configuration and settings, please share your experience.
Oh, I have disabled the haptic feedback completely and the clicking sounds universally also.

Charge the battery FULLY, & start discharging it, when it comes down to 5% or something, go delete the battery.bin (search the forums) or some such file. You need root. The restart, Viola, your battery is indicating the exact charge.

I dunno what tango exactly does but i can only confirm this: tango kills the battery in no time. even the newest version claimed to be "fixed for sgs", it still eats 5% an hour in standby just by adding tango.
besides, tango doesnt work very good anyway.

I've read about that by deleting the batterystats bin file, Im still looking for a solid explanation on whats exactly in that file, from my own understanding its just a battery usage history.

how are you using your phone ?
I see a lot of these threads talking about battery.
But bottom line is - How do you use your phone.
You have to compare apples withe apples.
Only 1 person in this thread described how he / she is using the phone.
Thats something you can compare with
I usually have mine running for 8-10 hours and have to charge. (almost empty then)
But im a heavy user.
Blutooth headset - Wifi - Sometimes GPS.
Aways on fastest netvork.
Exchange and Google mail, facebook and twitter.
Everything consumes battery.
BUT having said this -
I was on a vacation in France, and stopped every service, as im from another country and did not want to pay expensive roming prizes.
The phone now lasted 2-3 days on 1 charge, and this was all new for me
You get the drift
Forget about this battery charge discharge / charge delete stats thingy.
It will absolutely not give you longer battery run time.
Maybe the battery indicator will be slightly different, thats all.
Not worth the effort.
Hope this helps you

I think I found this over on the Desire forums but these steps have helped me immensely. I did these steps just last night, and I unplugged my phone at 12am and now at 9am it's at 90%, with 3G turned on with syncing once an hour.
With your phone on, charge it to 100%. Once it reports it is full, disconnect the phone and turn it off. Plug it in again, charge it until it says it is full (1 minute or so). Then disconnect again, turn it back on, and plug it in again. Charge it until it's full. Disconnect.
I find that after I do that, the battery life improves IMMENSELY for at least a couple days, or until my next flash (still testing).

If you checked what you posted you can see Im all over that thread, bottom line is that doesnt work for me what works is I just charge to full while the unit is off. Thats how I calibrate it and it always works on my end.

Hi, I also have a question regarding recalibration. I have the OCLF v2 installed and find / -name battery<somethingwhatever>.bin shows me 3 files batterystats.bin (I'm pretty shure this is because of the oneclick lagfix). Do I have to delete all 3 files or is it only necessary to delete the "real" one?

what would be the best kernal for me to have ?

my battery drains like a bugatti veyron doing 252mph constantly
so what would you advise . is the kernal i have now the best or should i change .. i dont want to reall lose much performance on what i have now but would like the battery to maybe improve if possible ...
from full charge taking plug out searching market for 2 mins the battery drains 5-8% in matter of mins
and i have only had the phone a week
With that kind of drains the problems the kernel won't change that much. There is probably a app that causes the battery drain so looking in to that will have more effect. Also the brightness/screen on is the biggest drain and kernel won't do much about that.
You said that you have the phone a week, the battery needs some time to reach it's full potential and you probably use the phone a lot because it's new. So use the phone normally for another week, after that week let the phone drain until it shuts itself off, leaf it off and charge it till it's full. (there is a different calibration method but this always worked for me)
What do you have now? Stock or rooted?
Sent from my HTC Desire using XDA App
First of all, I would assume that you don't use the phone non-stop (it would be justified to lose power in a few hours if you're on it non-stop).
I recently had issues with power consumption as well. What I did was:
1) check the built in battery monitor: menu-settings-about phone-battery-battery use. The bad thing about this monitor is that it does not differentiate well the apps consuming power, but you can still see if there's something wrong, as the most consumption should come normally from the screen and voice calls. For me, the most consumption was made by com.htc.bg, which, if I let the monitor on for a few seconds, would transform in the calendar app. Weird stuff. I unchecked the calednar auto sync from menu-settings-accounts and sync. It may have slowed the power loss down, but not significantly. I noticed a significant loss of battery by WiFi. I realized, I needed more information so:
2) I installed an app called 'Power Tutor'. What it does is, it calculates which apps consumes power, and it shows you in percentages. After install, you need to start the 'power profiler'. It will appear in your notification bar. If you let it run, after a few hours, you can see in "view application power usage" who is using power. That's how I discovered that my winamp app was really off the charts using power like crazy. So I went in the winamp settings, and I unchecked some options that could have determined this power consumption, like wireless sync, automatic mount as USB drive, etc. There was actually an option that was overriding the wifi power management, stating that the wifi does not stop after 180 seconds of standby. Basically, if you have wifi on, and you stop using the phone for 3 minutes, the phone automatically turns off the wifi. This was not happening any more, due to winamp. So I unchecked all those options, and voila. It worked, I have now normal battery life.
Good luck!
be aware of a couple of things
1. battery drain for the 1st few weeks are high because of a couple of factors, the battery "learns" and gets conditioned over a period of time (doesnt use the old 16hr charge process). its a new device for you so its a novelty, you probably mess about with it with the screen on more than you think.
2. there is a configuration within HTC's builds and in the memory chip of the battery to stop over charging. the device will charge to 100 and then slowly deplete to 90% while still saying full on the phone. as soon as you disconnect it recalibrates to the correct value which is anywhere between 90% and 100% depending at which part of the cycle you catch it
Some other tips to increase battery life, from a friend of mine in the Romanian forum:
1) use the app watchdog, it will warn you when an app is using too much of the processor and will ask you if you want to close it.
2) juice defender with the paid add-on 'ultimate juice' - with the correct settings... it's amazing.
3) Dial *#*#4636#*#* - phone information-network type: select gsm auto prl. The phone will stay on 3G when it has good signal, and switch to 2G when it doesnt, saving battery
4) Change the wallpaper to a static one, not a live one.
5) Go to menu-settings-accounts and sync and increase sync intervals for weather, news, or even set them to sync manually when you choose.
i will try and answer everything at once ..
ok my screen is on 13% brightness
i hardly ever use my phone , the only real use was to root , s-off, put ROM ETC ON
I reply to about 50 texts ish per day and search the market for literally 1-2 mins to see what new apps are in
i dont play games or anything
the thing the battery uses most is the screen and as i say i have it on monochrome theme with 13% brightness, there is nothing synced , i check automatically for email etc .. actually beautiful widgets is set to auto update every 4 hours
i never use wifi as i have a 3gb download/data usage, i dont use gps ...well i do but i have had no need to .. thats about all i can tell ya
rastaman the pt2 is a bit weird it should stay at 100 if just taken out of charge
I calibrated the battery and that made no difference.
