[Q] Why won't my N1 battery last more then half a day?

Hi I'm with Fido using an AT&T N1. My battery doesn't last me a full day. I thought maybe it was a defective battery, so I ordered a new one. This didn't solve my issue. I still have to charge it early in the afternoon and It's not like I'm watching video's it's just sitting there on my desk.
Anybody having the same problems or has a solution?
Thanks

Check what's using your battery, and act accordingly.

Are you on the wifis when it is at your desk? If not, how many bars of reception are you getting?

Root, undervolted kernel, more efficient roms, sync settings, apn control, brightness settings, battery calibration.
Welcome to android
Were all searching for ways to make our phones last longer/dynamic/faster.
Sent from my Google Phone

It says 67% of use is display, I set it to shut off after 30 seconds.
The wifi and BT are off.
Another thing I find weird. I have the dock. Every time i remove it from the dock and have to draw the password pattern, it's like the screen calibration is messed up. I have to close the screen and open it to get it working properly. This also makes it impossible to answer the phone when it rings while it's docked. I remove the phone and the slide to answer doesn't work as if it's not calibrated.

Check that your CPU isn't running at 100% frequency because of some rogue app.
Check that your phone has at least a couple of bars reception.

My N1 on AT&T runs 4.5%/hr usage when I'm not actively using it, around 6% if I'm doing typical stuff with it (reading email, web, etc).
It's on 3G, rarely use wifi (it's off), GPS is on, Bluetooth is on, K9 Mail is doing Push IMAP, Beautiful Weather is updating, misc other stuff is likely updating. Tasker is running doing lots of stuff, one of them is grabbing my GPS location and uploading it to my website every 10 minutes.
No IM, Facebook, or Twitter automatically running/updating.
I don't obsess over the screen brightness, generally leave it at Auto except when doing navigation in the car (It's never bright enough during the day) and I tend to pick dark themes but that's mainly because I don't like dark-on-white themes period on my phone.

Where does it say display use is 67%? In settings> about phone > battery use?

Does your phone feel hot? I notice sometimes that I'll be walking around and my phone is like burning a hole in my pocket, not literally but very hot. I noticed that when I installed wildmonks kernel and SetCPU that my battery increased TONS.

Some general things to check:
Auto email push
Cell stand by (look at reception)
Widgets auto refreshing
CPU frequency
I make sure all of the above is working properly, and my battery lasts for 2 days with light-medium usage

Sort of related question.... occasionally, I'll have "android system" just chew through my battery....if I let it just run for a few days, or if I clear the dalvik cache, it seems to fix itself, but I'm really clueless as to what is causing this....any ideas?

Don't know, but when it happens - it means the same thing I've mentioned multiple times in multiple different threads, some apps can cause the kernel to run in loop of some sorts - running at 100% CPU speed and eating the battery very quickly. Reboot sorts it out until it happens next time. Finding and uninstalling the rogue app sorts the issue, but it's a bit pain. Task killers don't help even a tiny bit, since they can't restart system service, and it's not the app that's running the loop.

Actually, for me, only clearing dalvik cache sorted it out. I had my battery die, swapped in a spare, and that one died within an hour or two....soooo yeah, reboot def did not fix the problem! xD

Use WiFi whenever you can. WiFi will more than double your cc very life over using 3g. Even just sitting there idle, its a huge difference.

[Q] Phone Signal and Battery Drain -- is there a correlation?

Hello Everyone,
I am new to the forum, but not totally new to rooting and flashing ROMs. I have a MT3G (second android phone to come to the market...yes I'm old school ), rooted and flashed CM7-Gingerbread 2.3.3 and it's working very well.
I also managed to buy a NookColor, immediately rooted it and flashed phiremod nook v5.1. and everything is very good. My Quadrant Score is 1485
However, what I've noticed is that if I compare the battery usage on mytouch 3g vs the nookcolor I see something interesting and I think it might have to do with the overall battery drain I've noticed on the nook....I'm hoping someone here can shed some light.
When I go to my settings > about tablet > battery use, I can see a graph on the top. If I click it, it shows a nice relationship between time (x-axis), battery % (y-axis) and underneath it are 5 variables (Phone Signal, Wi-fi, Awake, Screen on, Charging). These variables are key because you can see what is really draining a battery.
See the two attached images. One is from mytouch 3g and the other is the nook. What you can see is that when my nook is sleep, it drains a lot faster than MT3G and in fact what you see is that the PHONE SIGNAL is constantly on, where when my MT3G is sleep, the PHONE SIGNAL IS NOT....
Is there a way to completely remove this 'phone signal'...I suspect we can get more battery life out of our nook if we can just remove this!!!
Thanks for reading.

easy to do if you have adb.. otherwise use terminal.
rename the following files in /system/app
Mms.apk
TelephonyProvider.apk
Phone.apk (phone will keep forceclosing.
reboot.
If you are not using adb, just force power off using the power button.
When it comes up, you will have much better battery life.

Yeah, I saw that posted somewhere, and I've done that. So does the phone signal still appear on yours after you renamed it?
I wonder if this procedure is enough.....

Enough to remove Phone from being listed in Spare Parts? Yep. It won't change anything.

CM7 is really bad with the battery. It doesn't sleep properly. The phone or lack of phone has nothing to do with it. It doesn't have a cell radio after all ;-)
Apparently there is a bug and it crashes or something? when it sleeps. I read that the devs just disabled sleep until they can get it fixed. I think that will probably happen after video is all working.
It still easily lasts through the day with a fair bit of use though. I just charge every night instead of every third ;-)

Okay, so it's safe to assume that the devs are working on this for future ROMs/Kernals? I really like my nook even though I just got the wifi-xoom today.

There's already been a 20+ page thread on this, where comparitive testing found no actual diference in battery life by removing those functions. The result is a purely cosmetic change where the power consumed under "cell standby" is shifted to "phone idle" or something else, I forget exactly. Any perceived improvements in battery life are a placebo effect and/or simply the result of the variables in different day-to-day usage.
Removing them also causes Market problems with certain apps not showing up due to "incompatibility" with devices lacking those functions, which I suspect is why they are not removed in the first place.
The NC's "high" power drain on CM7 is because it's not allowed to actually sleep due too a kernal bug which prevents it from reliably waking up. This will get fixed eventually. Right now, "sleep" simply turns off the screen.

[HOT!]Charging problems, false drain readings, dialer issue, battery life, SOLUTION

Hey guys,
I would like to make your situation easier, so you don't have to read like 1000s of forum threads to get information I'm giving you here. These are the issues I faced with my incredible s, and the so called solutions.
The device:
Stock EU htc incredible s/ htc droid incredible 2 on Gingerbread. NO software mods at all.
According to my knowledge the same applies to the htc desire s and the htc desire hd as well. Most of these problems come forward after updating to gingerbread. If you are still on froyo, I wouldn' recommend updating.
1st issue. High standby drain.
According to Currentwidget and battery monitor my incredible s doesn't have lower battery consumption in standby than 38Mah.
Solution:
Drain readings are corrupted, there is a bug involved.
In reality You only have around 5-6Mah drain in standby.
Proof.
Left phone in standby for 2 days without messing with it, ended up with 40% left.
So if you have a minimum of 40Mah drain for two days. (48hours x40Ma=1920Ma) The battery's capacity is no more than 1500Ma, so it's obvious that standby drain readings are corrupted.
IGNORE drain readings!
2nd issue: You take it off the charger and it's 95%
Some say that phone charges till 100% than shuts charging down till battery reaches 90%, than charging starts again.
Some say our Lithium battery cannot get charged till 100% which is normal. This is the reason our device doesn't show % in notification area.
Solution: Ignore battery monitor, use inbuilt battery charge indicator, and be happy.
If you want to test battery life, start test at 90% and your test won't be corrupted.
3rd issue: Dialer using too much battery.
This might to be a bug as well. Still to be confirmed. The dialer doesn't use that much of power it only gets stuck in built in battery use indicator giving false drain data.
Some say it doesn't stop using proximity sensor after being in a call, hence the big drain. Incredible s's proximity sensor is visible during call, check it in the dark, it blinks. After call it stays inactive. So the dialer using it 24/7 seems to be a false statement.
4th issue: Declining calls in pocket.
When taking or declining a call, you swipe vertically on the screen. If you have your phone in your pocket with the screen facing your body, you can easily take or decline some calls when pulling out. This is more likely if you have a pocket made of thin material.
Solution: Put your phone in your pocket with the battery cover facing your leg. Don't worry about bumping into like a table corner and smashing your screen. Our gorilla glass is almost indestructible. Using a pouch or cover does the trick as well.
Not sure why htc is so obsessed with the vertical answer procedure. With horizontal swipe we wouldn't have this problem and users have been complaining about this since the desire came out.
5th Issue: Wifi disconnects when signal low, but still would be fine under froyo.
Connection gets disconnected when signal is 86db or lower.
This is a gingerbread related problem, htc cannot do anything about it.
No solution just yet.
For those who complain about battery life, I am on gingerbread with loads of apps installed and with very heavy use 3hours of display, wifi, skype,internet browsing I can use the phone for 12 hours. With moderate use min 2 days.
Battery saving tipps:
-Don't let google and htc sync. It uses lot of data and battery resources.(I don't like my sensitive data to be copied on their servers anyway.) Sync with your pc regularly.
- If u use data for e-mail and weather sync, use Gsm only mode, you don't need that much of speed for those, turn WCDMA on if u need it for skype, etc. Hspda and 3g are big battery killers.
-Everything on manual sync. There is a sync all widget in sense to use. U can hit it anytime you want to.
-No live wallpaper
-Hotspot uses excessive amount of battery. Use it on charger only.
-Screen light to be turned down. Use Screen filter app nighttime.
-Turn wifi and mobile data off when not in use, so phone can sleep properly. (wifi timeout app)
-Turn off wireless network positioning.
-Keep bluetooth off when not in use.
-Select short screen timeout like 15s.
-Screen on time is the main culprit in appalling battery life. Use your watch to check time rather than turning the screen on.
-If u struggle to find 3g or Hspda for data or network itself, change provider, because no matter what phone u have, u will have this problem. Try to find spots in your flat with better signal for data. Searching for network uses a lot of battery.
-Try to charge your phone from 0% overnight with the phone off for a couple of times (8-12hrs)
-When gps is on it doesn't mean that it uses battery. If you see the sattelite icon blinking or just on, that's when it uses battery, a significant amount of battery.
-Consider buying the official extended battery available in US (droid incredible 2 2100Mah), coming to EU soon. I wouldn't recommend buying the unofficial ones just now.
Obviously if you apply some of these battery life will be better. If you apply all of them, battery life will be exceptional.
Hope I helped.
Have fun guys!

Hi!
Thanks you for this! I buy my incredible s a couple of days ago, upgraded instantley. I met most of these problems and now I am happyer with my phone knowing these.
Could you give link to the battery you wrote about???

i appreciate what you're trying to do - but if you are going to follow all those steps you might as well have bought a nokia 3210
"Use your watch to check time rather than turning the screen on"
i mean.... really??

As I said, you don't have to follow all the steps.
You might face conditions when you need every drop of your juice, so it's good to know how to get the most out of your battery, isn't it?

It's for the droid incredible 2, but thats equivalent to Incredible s.

Sorry if this seems sarcastic, but if you're gonna buy a smartphone and turn everything that makes it a smartphone off, then save yourself a few hundred quid and buy a Nokia 1100
I use mine to sync everything and anything I want, and don't worry about it, as long as it lasts the day, which it does, I'm happy.

you misinterpreted what the op said. He is just stating what you could do if you found yourself in a situation where you had to maximize battery usage. Obviously most of us are around an outlet or usb plug most of the day so that we can charge the phone often.
Thanks for the info OP. I just wish that current widget would show us the right info. Or some other app :/

Thanks for the info OP. My buddy has had endless problems with his Incredible. I'll Chrome to Phone this thread and send it to him!

Its not the apps fault, the phone just reports wrong. So any other app should also fail.
@superman, perhaps a faulty app is causing the problems

Wifi issue should be resolved with the ota update.
However there is a network at my workplace which I couldn't connect to. I guess it is some kind of wifi repeater, it doesn't look like an actual wifi router. There is no cable connecting to it. Apparently I can connect but I get 0 signal next to it. Others can connect with full signal. Any idea?

It is FAR from "almost" indestructible. Some people also say it's impossible to scratch it, yet mines been scratched (this AND nexus one) It's nice glass but indestructible? I think not, not even "almost"

Live wall papers do eat your battery, but it's almost close to nothing. I've read that whatever uses more than 2% of your battery will be displayed in the "battery usage" I've used live wallpapers and it's never even shown that. (I think it also depends on what kind of wallpapers you use though.. let's say you had one that interacted with you) perhaps that might drain more battery.. but who turns on their phone to play with their wallpaper lmao
I've tested and disabling google sync barely makes a diff. I also don't think it uses a lot of data. I don't completely disagree with you though, manual sync is probably a better idea. On the other hand, I don't really think Hspda/3g are big battery killers, I notice that if you use the browser, the battery drops quick. Let's say you used "gsm" / "2G" and the webpage takes longer to load whereas 3G would have it loaded within seconds.. Which would waste more battery? I'm not 100% sure but I'd say just keep 3G and turn on 2G if you're not doing anything else with your phone. To my surprise, 2G is horribly slow.

Completely false. This is only a cover on top of your screen. It doesn't change the power being outputted to the screen. If you look at what RogerProdacter is making, you'll see that he's trying to modify the phones brightness output.

Disagree again. It's really up to user though, that's insane. I'd be pissed if my phone kept shutting off in 15s! What you can actually do is turn off the phone yourself or get something like Lock screen widget which instantly turns off your screen. Two reasons it's better - You don't have to worry about the timeout - you shut it off sooner than 15s.

[Q] Phone runs hot, High Drain - All usual fixes tested.

Device: Samsung Galaxy S GT i9000
Symptoms:
When Charging Device is hot to the Touch in the upper half of the screen and on the rear between the camera and the heat vent.
Battery drains at around 15-25% per hour when IDLE. 15% when in deep sleep in airplane mode with ALL APPS KILLED. 25% when I leave ALL network connections open and allow sync.
Phone was new less than 2 months ago. Still under warranty and I will send it back if no ideas come from this but wanted to see if anyone had a solution as I have noticed HUNDREDS of similar posts all vaguely scattered through different threads on different sites around the web and this seems like the definitive place to come to see if anyone can put their finger on it.
When did this occur?:
A short while after (days) of flashing CM9 nightly from the beginning of June (05/06 I think but can't recall exactly).
Tests performed:
Purchased new battery and fully charged - no change.
Flashed stock GB ROMs where the issue had not occured - no change.
Cleared battery stats several times - no change.
Tried different modems/radios including Nexus S radios- no result
Current ROM: CM 7.2
Kernel: Glitch 13.1
Other ROMs/Kernels where the same results were achieved...
CM9 (latest nightlies)
Stock JVU, JVS, JW4 and JW5
Semaphore Kernel, Devils Kernel
I use Voodoo Sound/Colour kernels apart from the testing I did with stock ROMs
Will leave it on over night after clearing stats so you can see for yourselves.
Any questions ask away.

I should add:
Used OS Monitor and one of the more detailed CPU monitors to look at what was going on.
Did not appear at any time to be using what I would consider high CPU utilisation, typically trending between 0 and 30ish. No background apps running, all radios turned off.
The only anomaly that stuck out at me is that system_server was using ~105% of RAM which I would have thought was rather difficult. Made me wonder if there was something loading/unloading itself from RAM.
As I am a heavy music user I have tested the Mediaserver issue where corrupt files are continually scanned by mediaserver process. Removed all media files from both my external and internal storage then formatted both while on a stock ROM (JVU and JW4). There was no change.
EDIT: I should add - The thing that makes this so strange to me is that the battery decreases at a rapid rate when Battery stats regarding usage DO NOT CHANGE. The percentages for the apps that WERE using the battery - i.e. winamp/mediaserver/android system do not change.
The reason I have posted this is that i have seen literally HUNDREDS of people posting this very same issue but never in the same place and never getting an answer.
Also - Thankyou to the kind mod/admin who approved my account so I can edit stuff. It was getting a bit annoying for the first week there.

Re
Hi,
To be honest I never heard/read of the problem you are describing. Most users report high battery drain on a certain ROM/kernel/modem but you say you have tried quite a lot.
If the phone is new, the only thing that comes to mind is that the USB charging socket is faulty. It may not charge properly or even have some bad connectors that are damaging the battery.
In any case, Samsung support is the way to go here.
Hope this helps

OMG, im having the same exact problem... the phone is super hot on the back where the sim card is inserted. I did everything as you, still no change, my battery lasts like 7 hours on deep sleep. Guess our phone is broken. super crap.

Anyone knows how to fix this? Is there anyway that my phone has some files from previous custom roms even though used odin to flash samsung original ones?

Had the same problem when my device was only 6 months old, the battery was becoming faulty, got a new battery and problem solved.

I bought a new battery and i still have the same problem... which battery did u get?

An official samsung battery from Amazon, re flash you device with another rom and wipe battery stats.

Did all that, the problem still continues... mega battery drain and the phone is at 44C degrees... is there any tool i can use to diagnose the problem?

Hi snaleman,
You could try BetterBatteryStats, to help diagnose your issue further, there is a paid version on the market (Google Play Store). There is also a thread on this forum, from the dev....hint
I tried winamp for android, ages ago, but had similar issues. (This player might well be your issue.) So I now use "PowerAmp". Neutron MP is cool too.
Also, do you use lippol94's kernel cleaning script. I use this every kernel/ROM change.
Search here for this:
ultimate_kernel_cleaning_script
Hope this info helps your baby.

Hey
U can try to flash a stock rom from sammmobile.com..
Use it for a few days and check...may help u..
Cheers

Backup your apps with titanium backup or something else.
Make a backup from CWM recovery
Wipe data/cache/dalvik
Restore user apps and not system app
If your problem is not fixed you can restore your CWM backup

Nothing you guys posted worked... battery lasts 11 hours on sleep...

Another problem that im facing is that when im on a phone call, theres is alot of breaks in the other persons voice and sometimes the voice call goes out and i lose all my network signal.

If you are using the Voodoo sound app that may be the cause. I've noticed on my phone that deep sleep no longer works when the voodoo app is installed, most likely the app is holding a partial wake lock and not releasing it.
See if it happens with the app uninstalled or frozen.

You've just made me think of something else that it may be.
Do you have 4 or 5 bars of signal strength?
I've found when in certain areas (very close to "deadspots" in network reception), that if I use another frequency, [eg. 900 & 2100 (for my network), yours may be different] I can get a better signal, also much better battery life, as the phone is not struggling to reach the network.
If you use your dialer to enter this code
*#*#197328640#*#*
Then
[1] DEBUG SCREEN
THEN
[8] PHONE CONTROL
then
[7] NETWORK CONTROL
then
[2] BAND SELECTION
you will then have a selection of frequencies available. The asterisk * will tell you what one(s) is/are active.
"Google" your network service providers frequency bands. I found mine were on a "Wiki" page.

[Q] Battery Problem??

I dunno whether it is a battery problem or what but I got a brand new battery
coz the last battery was too bad but the new battery also sucks.
I was wondering if it was cause of the ROM and kernel so
I switched to stock rom for trial purpose and still I got juz like barely 7 hours of juice....
with juz some files thru bluetooth and half an hour or so of texting....
so what could be causing the problem?
Here's the battery stats...

I'm not really an expert on this... but I'll try!
First, data - depending on how often your apps that use data refresh, it may be killing your battery because they are always updating in the background
Next, apps - depending on how many are open, and trying to retrieve info or a responce, this may be killing your battery life
Another, backlight brightness - I would say half brightness looks almost the same as full brightness, so turn that down too. Another thing you can do is make sure that your phone times out so the screen is always on and sucking the life out of your battery
Plus, bluetooth and wifi - turn those off when you aren't using them! They turn on in a couple of seconds so there is no use in just leaving them on and draining your battery.
Lastly, I dunno what "kik" is (the app running in the corner of the status bar) but it may be using battery too (probably not because it isn't in the list of the battery use so I don't think that's it.
Anyways, in short, possibly shut off the data if you don't always use it (you don't have to tho ), go into the settings of apps, and get the refresh rate at a longer period of time (so they aren't always using data), kill any open apps if you can with an app manager, turn down the brightness of backlight, change the time it takes to shut off the backlight, and shut off the bluetooth and wifi when you aren't using it.
Unfortunatley the battery life on the Ace is far from the best, if anything it's terrible, but other than that I have very few issues with the phone.
Well... That's my two cents. Hopefully it helps, but if not, search around on the forums and see if you can find any other solutions. :fingers-crossed: I'm not the expert, but I'm trying to throw ideas out there. Good luck

Running background processes is a major battery kill. I used to get 12h+ on 3G with Stocklite V6. Never used heavy apps though. Just Textplus, Opera Mini to check fb sometimes and WhatsApp whenever someone talked to me. Light usage.
How much the battery lasts depends on the user completely.

Lastly, I dunno what "kik" is (the app running in the corner of the status bar) but it may be using battery too (probably not because it isn't in the list of the battery use so I don't think that's it.
Anyways, in short, possibly shut off the data if you don't always use it (you don't have to tho ), go into the settings of apps, and get the refresh rate at a longer period of time (so they aren't always using data), kill any open apps if you can with an app manager, turn down the brightness of backlight, change the time it takes to shut off the backlight, and shut off the bluetooth and wifi when you aren't using it.
Unfortunatley the battery life on the Ace is far from the best, if anything it's terrible, but other than that I have very few issues with the phone.
Well... That's my two cents. Hopefully it helps, but if not, search around on the forums and see if you can find any other solutions. :fingers-crossed: I'm not the expert, but I'm trying to throw ideas out there. Good luck

First of all thnx for taking this much time out....
It's rlly helpful...
but
1. My data usage is barely 10 mb per day....
and no wifi and mearge usage of bluetooth....
2. Background apps;
only adw and one or two others...
and Kik is juz like whatsapp, a messaging app....
and it's quite lightweight, been using it since uite some time...
3. Backlight is at an always 25% and screen timeout 30 secs....
so juz wanna know if there's a possibility of some hardware fault......
coz I've tried most things possible to take out the software fault if any....

Wait, i just forgot!...
I get this too sometimes, but what might help is if you reset your battery stats! I have to do this too because I found that after a half an hour after unplugging my phone with no use I lost 10% battery life, for no apparant reason. Search in the Play Store "BatteryCalibration". All you have to do is charge your phone to 100%, and tap the button . You usually have to do this after flashing a new ROM, because you might not flash it at 100% battery life and the stats go from there. So I would say, try it and see what happens.
Now... If not... The only other suggestion I have is if you find a battery booster app such as "Juice Defender" from the Play Store. I tried using it, but didn't see a huge difference (I don't have data, so I just keep it off), probably because I barely use my phone. I've also heard some thing about a script called "v6 Super Charger" (I've only heard of it, please search it if you want to know more because I sure don't ). Aparantly it boosts battery as well, but no promises haha.
If you are really desperate for better battery life, I would say switch to 2g service in the settings. Other than that.... I'm out for now
Hopefully this might help you out as well, but other than that the Ace is not well known for a good battery. But that's a mid range phone for you (but the Ace ain't no slouch either)
Anyway, goodluck!

Ok, so after looking around a little, I found a very interesting thread about Lithium-Ion batteries! Really cool and really worth the read! I learned quite a bit. Hopefully this answers any additional questions that I wasn't able to answer!

Try also eliminating any widgets or live wallpapers that you may have running. These might keep the processor running at a higher speed then neccessary, but no promises.... Plus I already mentioned closing apps you don't need (so this is pretty much the same woops) and you might have done it already.
The biggest thing to remeber is that you have to sacrifice performance for the best battery life. This may go as far as underclocking your maximum CPU speed, but this might cause some lagging especially at the startup. I think that this should be a last resort to be honest, because you still want to use a phone, and not a laggy device that you are trying to conserve as much battery as possible.
I also heard something about the motherboard possibly having a hardware fault in it causing excess discharge... But... I will need to do a little more searching to see if I can figure this out for you!
The other possiblity is that you get a power bank... But that just adds to what you have to pack around, so this is probably another last resort, but it's all up to you.

Probably the best thing to do! Sorry I couldn't be any help to you, so it's probably best if you do that. I love my Ace, but the battery just has to hold it back
It sucks, but anyway, I hope you can get it fixed!:fingers-crossed:

Guys i face the same problem. My battery stays only for 1 to 2 hour. I tried wiping battery stats, full discharge and charge but of on use
Need some help guys.
