Battery drain help

My battery on my dell streak drains very fast. For example i had it plugged in until 100% in the morning. Then about an 1 hour and a half laater without using it that much it draimed to 67 %. The battery usage says cell standby 49% and the screen was 17% and those were the highest. From my nexus one i kno that cell standhy should not be that high. What is causing this to be so high? And why is my battery draining so fast?

Are you on1.6 or 2.1? mind was the same on1.6. Loads better on2.1. But I have also noticed that if you are in an area where 3g is poor it spend slot of energy trying to connect. I turn of data quite allot and it doubles battery life. BeforeI was getting less than a day now I get a day easily...... UnlessI have a load of widgets

Im using 1.6, then 3g then probably is the problem. Did u do anything to fix this problem?

I had similar problem and deleted my task manager, as amazingly it was using more battery than running applications
It also stopped 'fancy 'widget from updating, even when told to ignore it
'Appbrain' market was also another major problem, i also think that 'smooth calendar' doesn't help; but i'm still experimenting.

thanks for reply, im using advanced task killer, maybe i ll try taking it off to see if it affects the battery in anyway

If you look in the battery tab you should see where your biggest power hogs are.
Mine happened to be media.
I had removed all the media from my SD card, forced redection etc and it still drained the battery.
Eventually, I removed all ringtones and music from the SD card and did a hard reset, ran it for a full day monitoring the battery usage. Now I'm adding a bit of music back to see if it was a bad media file that caused the indexer to draw power.

For me the battery usage is almost 60% cell standby...then every other small thing piles in. Why is the cell standby so high. I would think that the display would be the highest

Delete ALL your apps
Weatherbug also drinks batteries, but it's so good this time the good outways the bad

I havent purchased my streak yet, does anyone know if 2.1/2.2 will have better battery consumption on this device?
you guys are scaring me..lol

Nobody can say for sure what the upgrade with have until it's released.

My experience is thus......
Widgets drain battery
T ask managers drain the battery, I now use watch dog
The biggest one by far.... The data connection drains battery. Especially if its a poor connection.
So first thing is to turn of 3g etc when not required. I get a day easily. If I add widgets I get a day just. This is with location gps and sync turned on all the time

I was haviing normal smartphone battery life, about a day, then started having some trouble so I uninstalled some apps. But, I also let the battery die completely overnight then charged it full and am now on day three at 55%

Day 3 at 55%? Do you have a SIM card in your phone? Data enabled? 3 days and only 45% battery life drain is unreal. I have a fresh restore and my Streak barely makes it through the day still, no widgets installed, no network-activity causing apps running in the back, no task managers. The battery life on this phone sucks.

3G has been on the whole time as well as wireless networking and gps. Bluetooth was turned off until about noon today. For widgets I've got Weatherbug Elite, Jorte Calendar, 3G Watchdog, System Info and Latitude. The phone has had pretty light use for the last few days because I was doing some work around the house, but I did use it for the occassional game of solitaire and as my ebook reader at night as well as a few short calls.
Today, on the other hand, I've made several phone calls (more than a dozen, some longer some short), have had bluetooth on half the day, wireless enabled and a small amount of surfing. I went from 55% at 8AM to 19% at 9PM.
I think the battery meter was in need of proper calibration and that's why I did a full discharge and recharge. I'm as shocked by what's happened as anyone else.
Oh, I've also had Juice Defender installed both before and after the full discharge/recharge. Before I did that I wasn't even getting 12 hours out of the battery and that's why I tried it.

Dolphin browser HD, no sh%t, my battery went from approx 95% to 3% overnight. 9 hours

My battery life has been pretty good for me, when I go to bed it's at 100%, come morning after 2 alarms it's usually at 97%. I usually have 3G & Bluetooth on. Then throught the day I don't use the phone much besides the odd text and odd e-mail, with a couple games of Robo Defence, and come 9 in the evening I'm usually around 40% which is pretty good considering that I get crap signal at work (very weak signal with the occasional signal drop) and I know that usually uses a lot of battery.
However, the other night, I went to bed with 100% on the phone and some time between then and 6 hours of sleep, the phone had died completely. Couldn't turn it back cos there was absolutely no charge in it...need to charge it a bit before turning it on. Quite worrying as I use the phone as an alarm during work days (luckly it was the weekend) and I don't acutally know what caused the massive drain

Thought I'd share my experiences here with you guys....
I've had my Streak about 4 weeks now, it's a US Beta version, on TMO US so no 3G, only EDGE. The only widget that uses data is Weather & Toggle. I have had sync and Facebook sync turned off, and only use GPS sparingly.
I tried everything - I started turning off the data connection (3G/EDGE in the top right menu) and basically uninstalled every program I thought could be using battery. Still, it would go from 100% at bedtime to around 60% in the morning. I then tried Airplane mode. Still was draining! I then installed Juice Defender, and it actually went from 100% to 0 - it died that night! D'OH! The whole time is was a 50/50 mix between "cell standby" and "phone idle". It doesn't show any programs using battery. I also tried Drain-o-meter, but it didn't show anything else either.
Well here's what finally fixed it for me -- turn back ON the EDGE/3G data connection and leave it on!!!
I'm guessing there are things running in the background (my guess is Weather Toggle widgets but the drain was still there even after I uninstalled it), possibly system processes, that require a data connection. In my case, that fixed it... now it goes down from 100% to about 92-95% overnight. Now I just leave the data connection on and it's all good!
I'm not saying this will work for everyone else, but hopefully maybe there's at least 1 other Streak user who has the same problem.

I was not happy with my streak's batteryperformance either (stock ROM), until a recent discovery.. It seems the Mail client (not gmail or touchdown) caused a partial wakelock if I had set it to 15min intervals (have 2 accounts) Draining approx 10% every hour.
After I set it to sync every hour, I dramatically increased the battery time.
Today when I checked it I had only used 3% in 5 hours (normally it would be minimum 30% in the same time)
I suggest you check your settings if you have the Mail client set up with accounts.
This changed my perspective on batteryperformance TOTALLY!

Bad battery life after 107 update

Just like the title says. I have checked all my settins syncs which programs are running in the background and so forth.. so im sure its not that..
Anyways here goes.
Before the update I could get about 12-14 hrs of use out of a full battery charge, however after this update I can only get about 5-7 hrs out of a charge.. Nothing had changed.. my usage is the same, my wifi,bluetooth,gps,4g are all off. I don't have any programs syncing or updating in the background.. So i have NO CLUE as to why my battery life cut in half after this update.

I already posted this elsewhere......my battery life was really great before this update.
Same exact settings now as before, plus the phone was reloaded to factory settings by the Sprint store first as I was having some other issues...email not coming through timely, cell signal falling and dropping calls, etc.
My battery life is now 1/2 of what it was prior to the D107 update.

I would say wait and see. When I would flash roms on my HTC phone the battery would die quickly for awhile. After 2-3 full charges it would go back to normal.

Check Cell Standby in battery status. See if Time without signal is 50% or more.

Cell standby is 18% and time without signal is 7%

My time without signal is only 2% So I'm not sure what is going on to make my battery life soo bad.

i got 9 hours today with decent usage where before if say 12 or so ... since the update my time without signal is in the 30-50% range on average & it was 3-4% before .. im a little frustrated on that & i know its taxin the battery a little so . . .

my update has really screwed my battery life. I notice too that Juice Defender keeps reading at 1.00x instead of 1.6-1.8 before the update. I also notice my TWS was at 50-52%. I tried the Airplane mode toggle and it didn't do ****. I really love this phone, but i'm about to return it and try another before my 30 days is up.
So far, i'm concerned with:
back button is not consistent (works sometimes sometimes it sucks)
TWS over 50% of battery consumption.
upgrade made juicedefender not work
little wobble in the phone but not too bad
scratched screen just from rivet in jeans
AND pissed about the tv out that sprint omitted

The back button is a defect in an early batch of phones.. If you swap it, you will probably get a working model..
My email app didn't sync after the update, so I had to reinstall Roadsync. It might be the same thing with JuiceDefender.

My battery is getting much better. Not sure if it is the galaxy rom, the update or my battery is just getting conditioned better. I unplugged my phone this morning and have been on it constantly web browsing, music, 4g, 3g, lots of tapatalk use. 36% left and just approaching 4hrs of being unplugged.

How do you roll back this update.
Sent from my Samsung Epic 4g using XDA App

after i re-flashed and updated, ive experienced big drops from the 90% zone to like 75% in a short amount of time but then the decrease stays pretty slow.
im using adv task killer on maximum and juice defender
this combo works pretty well for me, i cant explain the 25% loss. I think my battery still needs calibration, but i get around 14-18 hours normally.

I've noticed the increased battery drain also. I've been tracking it the past couple days with Spare Parts. If you open Spare Parts, click on Battery history. If your phone is running like mine is right now, the Running time is at almost 100%. That means that something is preventing it from sleeping. Next, click the tab that says "other usage", and change it to "Partial wake usage". Mine is showing that Android System is the culprit, causing the partial wake lock. It was not doing this before the DI07 update. I did a factory reset this morning and the only app I installed was Spare Parts, just to make sure it wasn't an app I was using. I get the same results on a fresh clean ROM as I do using noobnl's ROM. NOT COOL!

Well my full run through of the battery is over. I've turned a new leaf about the battery on this. I'm keeping the Epic.
Conditions: Was at zero brightness for about 4hrs of this. Set it to 0 after getting to work. You can see the screen perfectly fine at 0 indoors. (30 minute ride)
GPS - Off except the couple times I checked out google earth
Sync - full manual syncing / with background data on to use the market
Usage: Heavy heavy usage for all but 20 minutes. Total time with screen actually on was about 4 1/2 hours. Lots of tapatalk use, streamed about 20 minutes of CNN via Slingplayer, Streamed about 10 minutes worth of music via last FM. Dolphin browser usage. About an hour of total usage was over 4G
No task managers (well Androids but that doesn't count), no juice defender.

After all that it has been sitting at 3% for 20 minutes (after taking the ss) with no usage as I wait for it to finally die and write this post. Just over 5hrs straight of near pure 3g/4g data usage over various applications and multimedia is perfectly acceptable to me. This is WAY longer than the average consumer laptop would get under similar usage w/ an aircard.
If I didn't use the phone like a miniature laptop so heavily and just kept it to normal use and some phone calls with auto brightness on I'd guesstimate I'd easily get 10 hours or so if not a lot longer out of it.
Running: Andromeda Galaxy Rom 1.0.3

the reason your getting bad battery life is because it reset all your battery stats. it's going to take a couple days til your battery life gets better. try the bump charging method.

Crazy Android OS CPU usage

I am getting crazy CPU usage from Android OS, which is currently sitting at 52% battery usage. The CPU time of Android OS is between 20 and 30 minutes per hour! I have tried freezing many apps, I have tried task killers, rebooting etc. I have WKE7 firmware.

android os does use more than the rest, unsure why, but somehow the battery ife is still pretty good
http://goo.gl/cyd1T
KE7 (stock kernel) , full sync on google stuff + 1 email on push + auto brightness + about 1H of display on time on this, 1d20min and 68% left.
sent 3-4 sms and did a bit of various stuff since yesterday.
Seen worse lol

I would be very happy with that kind of batterylife. Sadly, my phone loses about 35% battery while I'm sleeping. With medium usage, I would usually reach 12 hours of battery.

i rate my battery life to smth like "amazing" xD

Yes for me battery life on sgs2 is also very nice - I'm comparing to sgs and it is about 20% better. My heavy usage today was 5 hours of screen on with wifi, some gps, 2h of gaming, skype running for about 3h, and battery run for total 9h. Also I use 2 push email accounts and sync is on. I think thats really good. And typically when I sleep in 8h battery is drained for about 8% with all email and google syncs active. So this is also quite good. All that on KE7. Most of samsung bloatware frozen.

Been trying to keep away from these battery threads, but noticed today that I've gone from android system 12% to 30% and I've no idea why.
Still on KE2, and am probably a "light user" - black wallpaper, brightness 20%, screen timeout 2 minutes, some phonecalls, lots of SMS, music - lots of Poweramp - shown a few photos, occasional wifi, GPS ca. 30 minutes per day, don't sync, don't use my carrier's dataplan, no e-mail as yet, and no Facebook/Twitter/games/Social hub/accuweather etc ever - in fact they were uninstalled on day 1.
Got 36 hours from my last charge, am now on 79% after 16 hours. Still happy with it, but no idea what has caused this spike.... Will keep an eye on it.
My $0.02 worth.

I am really starting to wonder why some people have amazing batterylife, while others are having terrible battery life. I would be very happy with 18 hours with 4 hours of screen usage, but instead I am barely scratching 12, today has been even worse. 10 hours with 3 hours screen usage...

So far mine is 2hr 15 mins screen on time, mostly browsing on 3G, 13 hours on battery, and have 29% remaining. Its OK, but I wouldn't describe it as amazing. Roll on 2.3.4

the thing is on android battery life largely depend on apps and setup anyway

Yeh, I know. But I feel like I have optimized my setup as much as I can. No autosynching, email check every 2 hours, facebook, twitter and RSS updates ever 4 hours. No GPS, automatic screen brightness, wifi sleep on. No widgets pulling real time info.

mine has the stock weather widget and animated background - also wifi always on (that prolly actually helps ..)
also i used some gps,played short videos, youtube, recorded some vids and took a few pics (you can see i used it more heavily today in the graph)
im supposing a lot of this goes as android system (bug?) cuz its certainly intensive and isnt in the list (not even lower)

Get rid of the auto screen brightness. I find brightness of 10% makes a huge difference. This samsung screen might look great but in fact it's practically useless as it drinks power

with ke7 as u can see auto brightness doesn't seem an issue for me anymore
i like it because i don't need to set the brightness in sunlight when it's auto hehe

What is your CPU time on Android OS vs. total battery time? Right now my phone has been on for 2 hours and 14 minutes, and CPU time in Android OS is 43 minutes!

If you've read through the majority of these threads, what's weird is that some of you that have uninstalled and/or frozen specific apps are getting worse battery times than those of us that are bone stock and have everything whirring in the background. As an example I use Wi-Fi a lot and also Kies Air and connect to a Blu-ray player using Wi-Fi Direct. The Wi-Fi Sharing app never appears in my running apps after I turn Wi-Fi off. Yet some of you with tweaks that don't use Wi-Fi have it randomly appearing and eating up CPU time.
I've kept up with this thread and other battery threads and for every "ah-ha!" moment there's a post following it showing worsening or no improvement. Somewhere in one of the three battery threads there were some tweets from Google acknowledging the problem in running 2.3.3. with dual-core processors. I think other than for the mad scientist fun factor we're just beating a dead horse and 2.3.4. is going to have to be our salvation. There's not even any assurance that a cooked ROM sans all the Samsung tweaks would work any better if the issue really is a core-OS problem.
Back to our ongoing debate...

Battery problem

I know the battery life is not the best on this phone, but today my battery died very quick.
I fully charged it in the night, than unplugged my phone at around 12:30 AM when 100%, then I used my phone to some calls at 9:30 AM.
When I checked my phone at that time, the battery was down to just 51%
I just have a normal Wallpaper, Bluetooth and GPS turned off and only used the phone for less than 15 mins top since being fully charged, how did all the battery die on me ?
Android Version 2.3.3

Did you install the stock XWKE7 kernel like it says in the OP in large red writing (IIRC). You could also install the XWKE7 CF-Root package

Hmmmm .. Actually I have the "XWKDD" I'll try "XWKE7" then give you my feedback after testing it for couple of days.
Thanks ..

OK .. here's the thing, I fill up the battery at 11:00 AM with 100%.
I made 2 calls at 11:33 & 11:44 AM for several minutes.
I record several videos for several minutes in HD & take some photos as well. By the way the wifi, data network, GPS and bluetooth are off. It's also in auto brightness.
At 07:44 PM the battery reached 77%.
At 12:00 AM next day I surf the market with wifi for 30 min and left the wifi on with no apps running in the background. At 12:00 PM the battery was died.
In the other hand, the iPhone 3G with the same settings in the same time when the GS2 is died the battery was 45%. The old iPhone 3G completed a day and a half.
So, what do you think ?

smaller screen, different technology, less pixels. The iphone doesn't do multitasking. It also doesn't power 2 x 1.2ghz processors. It powers a (I think?) 400 mhz. Those are some starters

Could you post a screenshot of your battery stats?

Hmmm .. reasonable. BUT, still most of the reviews say that the battery can reache 12 hours in heavy duty.

Please re-post a screenshot of the apps usage in stead of the graph!
I have recently fixed my battery issue. I was getting aound 8 hour the first 3 weeks. But after freezing a single process "wifi sharing" I am now getting 20 hours. My usage is the same. This wifi sharing process would run even when wifi was turned off and also on all the current firmwares. I've spend the last two weeks testing all kinds of things, taken thousands of screenshots on the way.
Let me know if you need more details.

I tried to freeze the "wifi sharing" through Titanium Backup but it need the Pro version is there another way to freeze it ??

My drain, with latitude.

I really can't understand all this complaints about battery. Here is a shot of my stat. I didn't use the phone too hard in this period, but it usualy can stay for almost 2 days with 1 charge. I never rooted the phone.

Normal you don't have the problem, your phone isn't awake, how do you setup your phone (wifi, sync, etc)?

Well, I just made wifi to turn off in idle. Bluetooth and GPS are on all the time, sync with google account (no idea how often it do the sync), weather refresh is every 2 hours. Mail accounts are setted to manual sync. No facebook at all. KE7 firmware.

Manual Sync may be the key, i'll try.

Any ideas why my battery suddenly dropped like this and then even started increasing without charging the phone ? lol

damn thanks button next to the quote button ;D
discharge ur phone til it shut down once to calibrate (just once) then charge full

I'm going back to the stock ROM and test it. If it's drain my battery as will as the Villain ROM (hopefully not) that means either the Samsung ROM or my battery has a problem.

[RESEARCH] Zenfone 5 1.2Ghz Screen On Time

As the title said, I'm gathering some information about screen on time (SOT) of Zenfone 5 1.2Ghz (from 100 to 1-5 percent)
I want to see how my battery is after years by how much time it can handle now. Hope you guys help me.
In comment section, please including your SOT plus:
- What rom are you using? (Kernel version if can)
- Most used network: Wifi or Cellular
- Network setting: Always on or Never (Manually)
- App ram usage (Running Service in Setting/Battery or Develop Options)
Thats all I want to know for now.
Thanks!

Using stock rom Kitkat newest version, cause it uses much less battery!
I mostly use more of the Wi-Fi on always on
what is mostly using my ram is the screen ( brightness) and android
I will send more information about RAM usage later, my phone is recharging

Using 1.6ghz variant.
rom- resurrection remix nougat. but channging of roms didnt had any great impact
only wifi always on.
ram- 40-50% or below free.
sot i get varies from 2hr- 3hrs. only texting and light stuff gives around 2hr 40mins.

im using latest kitkat on my 3 years old zenfone 5 single sim variant.
this one with 100% cpu usage all time + [ full screen brightness+ bluetooth + wifi+ gps on ] from 100% to 5%;

How long screen on time did you get? That's quite impressive battery graph with wifi and gps always on.

Screen was always on in both tests. i used battery drain app to make screen always on with full brightness and wifi in second test and i get 3h45m screen time.
in first test i pushed cpu 100% and activated all gps/bluetooth/wifi etc and i get 1h53m screen time. but phone was really overheated and i scare to do it again (it was burning my hand)
actually i was shocked myself when i saw 4 h screen time when i used my phone to only read ebook all day in home with half brightness and i decided to test my phone. Results were amazing i agree, i hope it keeps that way for one more year.
i tested overnight battery usage and it dropped to 85% from 100% within 7 hours with wireless open while android sleep. i guess it might be better to close all network overnights

I wish I still kept the screenshot on Mashmallow to show you.
wireless is not the reason but the google play service. After disable a list of unneeded services, I let wireless enable all the time, gmail and other notification still can be recieved and battery drained 1% per hour (screen off). For specifically, after 6 hours over night, it will drain 6%.
screen on time is normally 3 hours but of course I have to tweak a lot to get this result. If not, battery just drains like hell.

i tried to close wifi yesterday , as you mentioned it does not effect the drain.
3 hours sot on marshmallow is great but unfortunately i cant use custom roms cuz i need Gps occasionaly and my simcard often keep loosing signal on thoose . i am considering to get a xiaomi mi or redmi phone by next year but until that i had to use asus zf5 with kitkat 4.4.2 and 3-3.5 sot is best i can wish for.
