X10 battery lasts about 4 hours from 92% charge .. Wtf!!

Hey guys, , i apolagise in advanced if this topic is coverd, ive tryied to search but didnt find any related topics.....
Anyway...
I went to a 2 day festival took my x10 - WASTE OF TIME!!!!! couldnt even use it!!!!
Battery had died within first day, with hardly any use and 2nd day i had it charged for me up to 92%...
Checking the times every now and then on the 2nd day from 4pm onwards, i noticed by about 6pm my phone was on 50%, so i was curious about this as no wireless connectivity were turned on,
so at this time, i then "downloaded" from (GSM) not 3g. as coverage wasnt that good, advanced task killer.. i killed ALL my apps.. and carried on as normal, (only checking my phone for the time).. by 8pm i was getting messages saying 15% battery... and then 9pm my phone was dead :/ .......
No wifi, no internet surfing (apart from downloading advanced task killer) no bluetooth no gps..
Used my phone for a couple of text's and a couple of phone calls. NO WAY!!! should that have used all my battery up... Is their somthing i dont know about ??????
thanks

You gotta drain your battery s few times when you first get it. Also task killers don't really help with battery life. Imo they worsen it. Thirdly upgrade to the latest firmware

+1 to that. Don't use task killers, let android do the work, it knows best what to do. what firmware are you using atm?

X10 battery issues has been covered big time
So has in call volume ...
I had the same first few days as you and was pretty dissapointed in the X10 but now things are much better. You do have to cycle the battery a couple of times and you'll see some improvement.
Most of the extra battery life really comes from using newer firmware. Since you didn't mention yours it's difficult to say if you are above or below 023. The 023 firmware seems to be the spot where most of the increased battery life came about.
Since I still wanted more I switched over to a 2600mAh battery from Cameron Sino. Now I have trouble killing the battery

There is something else that might be contributing to the problem... There are a number of apps and home screen widgets out there which are badly written and prevent the phone from sleeping, and therefore drain the battery like a *****... you should try a Factory Data Reset and then add your apps and widgets back in 1 or 2 per day until you have sussed what was causing it.. I had terrible trouble with Weather and Data widget killing my battery for a while..

Good point about the Widgets.
It would be nice, as a matter of fact, if there were a topic on Widgets that cause battery drain. I've read a few posts about specific widgets but have never seen an ongoing thread. I'm off to look for volunteers.

I seriously dont get these battery threads. I know this dosent help much, but I honestly get over 20 hours on a charge consistently, with WIFI and 3g on.

4h only?
Pretty much is a faulty battery/device.
I saw a movie with brightness at maximum using BT with wifi on at the same time and i still had 60%+ left.

Wow that sucks... I think your battery needs to be replaced.
Mine lasts about 4 DAYS

*#*#4636#*#*
Battery history and make sure the phone is sleeping when not in use.
If its showing 100% or close to 100% then an app or something is preventing your phone from properly sleeping.

!!
my personal experience on two batteries one 2 year old (from x1) and brand new one gave me 7 hours of intense usage wifi ( i don't use 3g ), texting gaming and in the mean time playing music after first update, before was maximum 5 hour , also need to mention i need to remove every task except what i'm working with task killer cause in my case every 2-3 hour for some odd reason i have at least 20 apps restarting again in the system which drain battery like hell , time scape and media scape use lots of battery life in auto connect mode so update it whenever u want them , gps is a drainer too i just use it when i'm desperate be careful some programs may automatically use gps without asking! also should say compare to x1 the speed of the lock is at least 10 times faster and not i can get it indoor near the window as well (its cool) !!!! hope energy roms come here as well cause they will blow your mind!

Just update to the latest firmware version and your battery life will be just fine.
If not you coul'd update your phone, root it, install setcpu, and get rid of Timescape & Mediascape.

Battery drain problem/sensor usage

I got a heavy battery drain after flashing to the official Kies 2.2 here in Norway, on JM2 I had over two days usable time, now down to a normal day.
I've reset it several times, tried running it without any apps at all, still heavy battery drain. After checking the battery statistics/history I can see under "Partial awake time", Android System, 2 hours after 14 hours "uptime". And under "Sensor use", Gallery eats up 9 hours, 11 mins. Now what the hell is that about T_T
At least waiting for the new official fw in november.. At least the GPS got better for my part, so it's not all bad

After updating to the official 2.2 that came here in Norway, I started experiencing heavy battery drain compared to before.
After some digging I noticed under *#*#4636#*#* and Battery History and Sensor Usage, Gallery is on top! And it's using the phone's sensors almost 100% of the time it's been on. So, now; the phone has been unplugged for 12 hours, 14 minutes, and Gallery has used the sensors for 12 hours, 4 minutes. Doesn't make sense.
I suspected wifi to be the culprit to begin with, as it throned at the top in the normal battery drainage-graph (about phone, battery usage), but even if I turned off wifi, 3g and autosync over the night, the battery percentage fell just as quickly.
Now, I've tried resetting the phone several times, as I thought it was an installed app that caused the drainage, but that wasn't the case. So, what else can I do when a reset doesn't do it?
Using a GT-i9000 with JPM/JP6 non-rooted.

Well, for what it's worth I too experienced exceptionally high battery usage when I updated to JP6 via KIES hack (same version as yours). Downgraded to the latest stock ROM for my region (Eclair JG4) and the issue is gone.
Now I think I will wait for the official 2.2 update for my region (although, having had a peek at what Froyo has to offer I think I can pretty safely even skip it without missing much).

I too notice a lot of power drain and general lack of ram. What I found was that froyo has a crapload of startup services/processes compared to eclair. I disabled most of them that could be removed and replaced most of the rest like k9 for email and handscent for messeging. System seems less laggy due to more free ram and more power as CPU isn't bogged down by extra unwanted processes like samsungs remote wipe and stupid sns

I'm also suffering from battery drainage with Froyo (JP6). I was quite satisfied with battery use on Eclair. Froyo has reduced battery life almost by 50 percent. I have same programs and I'm using exactly the same settings than with Eclair. I haven't noticed anything odd from the battery history statistics though. Only strange thing is that phone reports that screen in consuming over 90 percent of the battery all the time. Well, that's just not true.

it's a sensor issue, looking at the spare parts batt usage stats. but no idea what sensor/app is the culprit. very annoying

An App I use daily for all manor including checking battery usage is 'SystemPanel'. It's been a God-send and sorted out many a problem.
There's a Free & paid version but the App is that good I immediately went for the paid App.

In 6 hours battery has gone from full charge to 85% in standby mode.
Is this normal? Charge goes awfuly quick when using the phone.
3G on, all syncs off.
Running on Froyo reg hack. Same problem on Eclair!

Phone is 85% charge from full charge on idle over 6 hours.
3G is on, 2 bars showing. WiFi on, not connected.
Display 50%, WiFi 30%, Cell 14%, Phone 6%
Froyo, Eclair same usage except Wifi connected better with Eclair on home network...
2 meters from wifi transmitter and signal fluctuates.
Also, anyone's stock browser lags with yogurt? Was good on eclair
Is it because of fash? Seems to lag on all sites now.

Just to add to this... I had similar battery life in Froyo... HOWEVER, yesterday I used the Gallery and my battery drained from full in under 10 hours with no use (overnight standby with data off).
I check my battery stats when i switched my phone back on and they're okay for the 'since last unplugged'... however... for 'all time' gallery is also my highest user!
So, looks like gallery is only a problem if you use it... if not, it's fine.
crabby

I also have like a 2hr sensor usage on my gallery...
About the light sensor atleast on the JPM/JP6 theres like 2 steps of brightness full and low.. is this normal ?

+1 for that app! Paid one with possibility to see history over time..

Sensor usage for me was also 100% in spare parts, even if the phone was off. I had to turn off auto-rotate, and it quickly became a lot less. Although I have to say it haven't solved my problem! My battery consumption with full brightness over wifi is 10%/30 min. That's just ridiculous. I'm still on the problem, and will update anything I find out. We could actually make a "BIG BATTERY DRAINAGE" thread, where everybody posts detailed logs about the drain.

i'm on jp6 and my gallery is eating up my sensor usage too ):
looks like I've got to restart everytime I use the gallery.

activate monitoring under "menu / settings tab"
then you can see look under menu/monitor and select history tab..
on top tab where it says plot you can select top apps.

just a question. you guys that are experiencing the sensor issues, are you on jp6? could it be a jp6 issue?

Exchange email accounts are a huge drain to in Scandinavian Froyo
If you set up Exchange email accounts, setting the Email retrieval update interval to anything else than 'Never' results in a continious 10% CPU load, draining the battery two times faster than in Eclair 2.1
Set it to 'Never', or have Tasker kill the Email app x seconds after Display Off
Determined by using System Panel app.

I have notice a large battery drain overnight with the OFFICIAL samsung froyo JPO. I suspect it may be the gallery/sensor issue.
1 can anyone affirm this.
2 can we replace the gallery or fix it
tanks

JPA was better for me. With JPO I noticed that the media scanner would eat up the CPU all the time. It seems to get stuck on certain files more easily.

My experience with GREAT Galaxy S battery life!

Hello Everyone!
I made this thread hoping I can shed some light to those getting very poor battery life. I was also getting very poor battery life, till I went and exchanged my phone for a new one. If you're getting very poor battery life (even after wiping your phone or installing a clean firmware), there is definitely something wrong with your phone or your battery.
I own a i9000m bought from Wireless Wave. I've unlocked the phone and am now using it on Rogers.
My previous phone, I was draining 25% of my battery to just get through 6 hours of standby while I slept. I had juice defender on and autokiller memory optimizer. I turned off all syncing and didn't even use a live wallpaper. My phone was rooted and also had lagfix (which I soon removed). One thing I do remember doing is not charging to 100% when I first got the phone. I did accidentally let it drain to 0% cause I had to use it right away.
After exchanging for a new phone and charging it to 100% right away, I was getting the following results. I have juice defender and nothing else. I changed my band to be WCDMA only. I even have a live wallpaper on. Last night my phone idled for 9 hours and it only drained 2%! Last night going out, I had a moderate to heavy (fbook, 3g, gps, text, youtube) usage pattern on my phone and it only drained 40% after 6 hours of use.
I don't know what else to say, but I'm letting those with battery problems know that the SGS is capable of great battery life. And if all your optimizing and tweaks aren't doing it, then you may want to consider exchanging for a new phone if you still have warranty.

I have a great battery life too in my device compared too the another smartphone i used in the past and now compared to Ip4 and N8 in this devices the bat drain is much higher. So im positive surprised with
the galaxy battery performance, i only use the push email everything else is turned off, livewallpaper and so on..

My phone came with JM7 firmware. My battery life is just excellent, not needing a recharge before a few days with my use

Running JPM here, with darkyy's raw metal ROM, my battery life went up by at least 40% - %50. I was losing 1% per 5 - 10minutes of usage, now its more upwards of half an hour of usage.

I think the phone has very good battery life if you understand what can cause battery drain and adjust it accordingly.
I am now gettining 5% drain per 24 hours on (almost) standby. This would give me about 20 days of standby which is crazy.
Here is my setup:
UK 16 Gb Galaxy S with Eclair JM6 and Voodoo lagfix
Set network to GSM (2g)
Disable internet usage (with APNDroid)
Disable WIFI, Sync Off, GPS Off (with power widgets)
Just before I go to bed, I run Advanced Task Killer and kill anything that doesn't need to be on memory (inlcuding Advanced Task Killer itself).
Using your phone WILL spend a lot of battery. Browsing the internet on 3g is a battery killer. This means that if you do something on your phone that maintains an active 3g connection, it WILL drain your battery in about 3-6 depending on your 3g coverage.
WIFI is better, but again you are looking at something between 6-12 hours of continuous usage, so make sure you only use it when you need it.
Finally, if you need to have your emails the instance they arrive, go for a blackberry because it has the only way of pushing email without maintaining a constant data connection.
I don't need this so I am extremely happy with my phone and the battery life I can get out of it.
I hope this helps.

Have my phone set for 2G with wifi always on.
Use wifi at home.
2G is enough for all normal syncs, and if I need more speed for anything else I temporarily switch to 3G for that.
This way a single charge last me well over 24h under normal usage. Don't even know exactly how much.
With the phone set to 3G, the same usage patern will eat a full charge in something like 8h.

JPM Rom with everything except bluetooth turned on my battery lasted 3 days with low usage (skype a few times and some phone calls and a bit of wifi web-browsing.)
Much better than my wife's iPhone 4... Normally charge it every 2 days.
I am very happy with the phone, just a couple of bug fixes and I would really like it if Swype did some level of contextual checking of words to help minimise unnecessary corrections (perhaps they do already, but it is certainly not well implemented/sophisticated enough).

Eclair for both. No Froyo.

what i wish to have is greater control over the phone, more easily.
Some kind of powertop GUI that let you see the power usage per process.
So you could plain uninstall apps installing ****ty services consuming the battery.
Likewise i'd like *real* control over which background services are running. I mean running an auto killer wtf? Horrible design!
I just want to switch off a service and that it doesnt start again 5 min later thank you very much.
Even the task manager is quite bad. You see last started apps but you don't know which one is running right now. And if its running and backgrounded since a while and you started other apps.. it might very well not even show up in the list anymore. Horrible design again.
Saying all that because stock the phone battery is excellent, installing a couple of popular apps kills it..

Thanks for your prompt reply. Could you check it more precisely on your current SGS? FYI: Settings -> About phone -> Baseband version and Build number or "call" *#1234# -> PDA, PHONE, CSC version numbers. Thanks in advance.

Sure thing. And thanks. KIES offered an update from JM1 baseband and JM2 build version. We'll see how the new ROM performs in about 3 days. Unfortunately don't have spare time to do that sooner. I suspect there's huge difference within the baseband versions.

hey guys.
i have galaxy s i9000..i also had problem of battery.my battery would hardly last 24hrs...i even switched to gsm only mode n switched off sync.but still had same prob..few days back i installed JPJPA firmware..now its wroking fine.lasts more than 35hrs...n also battery charges quickly

Is it possible that the reading on the phone is wrong? When you say you are getting 24 hours are you letting it run flat.
Alternately is it saying the battery is running low and you recharge before it goes flat?
Just wondering if the meter is simply giving incorrect information.

Been 24 hours since last recharge. Lost 6% so far. Running JP6 Froyo. Rooted. Network Data Off. During this 24 hours, just used Angry birds-30mins and ColorDict 5mins. Haven't installed any unnecessary app.
Had lost 1% on standby after 14hrs with no usage. Thats amazing. Very Happy user.

Also want to tell u guys that GPS with active Data connection and Google Maps running and display on took approx 1% of battery every 3mins.

Impossible using stock battery, this phone draws a minimum of 10% battery per hour the screen is on. Its more likely 15-20% with most peoples phone.
Your battery meter may be inaccurate, for example after flashing once my battery stayed at 100% for hours then suddenly shot down to 20%

I use "Battery Indicator" to check my battery status.
My screen is set to turn off and lock after 30 seconds of idling. So it is quite possible to achieve the standby times listed.

Hi, how long do you have holding time of battery, when you are using wi-fi? (browsing)

Terrible atrix battery

I've unlocked and am running Ken's Alien ROM and so far I really like this. Im an international user on orange uk, so I use faux123's kernel for Oc and ram fix. But there is one caveat. I have really rubbish battery life. I did all the stuff (charge to 100% from 0% wipe stats, calibrate). The fact is, I left it on, for ten hours. The display was on for about 2. No usage. When I returned the battery was 30%, with phone idle consuming 30%. Newer radio needed? What can I do? My baseband is N_01.95.00R .
I've heard good things about the newest AT&T radio for battery. How can I flash this to an international ATRIX?
Help appreciated

Edit : phone idle consumed 40% :O

I have the exact same issue. Unfortunately, all that I can say is that changing neither kernel, radio or rom did fix this issue. I had some improvements when I followed this topic and flashed back my stock kernel (with no OC), but still very far from what I would consider a decent battery lifetime (10h with 3g + email and twitter sync and screen off)
Some users have tried and it worked well from them. I'm on the team that didn't work ): But you could give it a shot

Calibrate your battery. Charge to 100% wipe battery stats. Then discharge to shut off. Then charge to 100% again.

I've done all that stuff, but it doesn't help IMHO. (at least it didn't do anything for me)
Only 2 real fixes that have worked for me are these:
1. Freeze unnecessarily apps with Titanium Backup (use "System panel" from the Market to find out what keeps constantly running/popping up in the background that you don't need)
AND
2. Turn off Automatic Sync, and get in the habit of doing that stuff manually all at once.
@2. I use to sync in the worst signal areas, and that drained the **** out of my battery. Sync/get your updates manually in strong signal areas whenever possible...

New radio from the fruitcakes thread and the latest faux123 kernel seemed to kill that bug.
I sold my atrix to my less then nerdy friend and I just fixed that bug for him yesterday. Same deal tho...

I noticed from X2 battery (I think) every minute or two the phone constantly checks for either cell or data signal. I can let my iphone 4 sit on the counter all day and it might use 1-2% but my atrix drops 5% in an hour without touching it. No calibration or battery fix will help. Even CM7 uses it fairly quickly. Im running Alien 4 with max battery saver and gps and auto sync disabled...it should last for a full day with heavy usage.

Alien 4 w/theme, faux123 kernel, everything at stock settings for this rom, nothing frozen, and I am sitting at 1 day and 13 hours with 28% left, mostly idle, but an hour long call and bit of game playing.
If you are getting something on the order of just a few hours then your phone or battery must be bad. I am doing nothing to extend the battery life other then using the default settings.

The phone should get 2 days sitting on the counter..LOL Of all the phones I've had and iPhones I've jailbroken, there is definately something wrong with the Motorola or Android software running on this phone. I've never had to worry about calibrating or battery fixes. This is just my honest opinion. I've had 2 ROMs in all the ones I've flashed that had good battery life and I think it was a coincedence that maybe something didn't load right or got deleted by accident.

Most iphone users need to charge at LEAST once a day. A lot of them charge more than once. I can sometimes get 2 days usage from my Atrix, with heavy texting, some calls, and some games - which is pretty damn good.
Maybe your battery is the issue. not all Atrix are created equal and not all batteries function the same

When you go into settings>running apps, does your free and used ram add up to over 800? Mine used to and now it doesn't. It adds up to like 750....I always thought it would add up to mid to upper 800's. It also could be the battery but I was pointing out that I have left my wife's Iphone 4 and my atrix on the counter all day (neither one got used) and my atrix was down in the 70% range and her phone was at 96%. I'm just thinking something is running or consuming the battery. I've used fastboot to do all wipes and still seem to be having an issue.... I also flash ROMs every few days so maybe the battery calibration doesn't have time to really calibrate. I'll pick a combo I like and keeep it for a few days and see if I notice a better battery life.

How long has it been since you've flashed a ROM? It usually takes a few days for it to settle back in and provide decent battery life (at least from my experience). My phone right now has been on for a little over 7 hours and is at about 55% with Display using up 60% of the battery (3hrs on). This is with the Alien v4 and Faux's latest kernel. The first few days after flashing a ROM my phone would usually only last about 7 hours.

i get 2-3 days on stand by. and about 6-8 hours of straight use. 3-5 if i'm using mobile broadband.
1: keep gps and data off (background data is almost irrelevant.)
2: use green power
3: use a task manager to close applications that you are not using. (be sure you can add "ignore" exceptions otherwise get a different manager. anyone who says not to use a task manager is a ****ing punk hipster ***** fag who's irreparable damage to the geeks good name will not go unpunished)
4: do the "wipe battery stats" bit after every flash (100% charge, wipe stats, full discharge)
5: is to install a custom kernel and use SetCPU to underclock to 312 while the screen is off..
most importantly: use your head. if you stream 1080p using mobile broadband for 2 hours your battery is dead.

I flash ROMs every few days but I call BS on the whole "Battery Calibration" thing. If my battery is showing 4200mv...it's full. It will die faster the more processes the phone does so my point it....whether I flash a rom every day it shouldn't matter, if the phone (After I set up and install whetever apps) gets unplugged, something drains the battery. Maybe the infra red sensor is always on, or a process is always starting and ending, who knows but the battery cannot be calibrated, the phone might need to be calibrated to read the correct voltage but batteries don't hold memory unlike the old NiCD rechargables from years ago.

When you flash a rom the battery stats get messed up. Based on what I know the way the battery drains depends on previous battery usage data hence the reason why it last longer after a few days of use after a rom is flashed. It needs to build up new data to correctly report battery use. Maybe I'm wrong but my experience supports this.

I am running Alien v4 with the stock kernel and I am getting well over a day with pretty heavy usage (phone calls, texts, emails, FB, twitter, XDA, Games). My setup:
Battery Mode= Maximum Battery Savings
Auto Brightness off, usually on 30%
Unused blur apps frozen
Reinstalled performancemanager.apk (blur task manager), set to kill unnecessary apps after 2 minutes of inactivity
No overclock, I don't see the need to overclock outside of high benchmark scores. Without overclock I still play every game smoothly without any hickups or slow downs. The phone still feels super fast without it.
I turn off all unused services (gps, bluetooth, wifi)

After you charge your phone and take it off the charger, reboot it.
It seems that a process kills the phones battery after you take it off the charger. You have to reboot after taking it off. It works wonders. Currently on 16 hours of use @ 45% battery on alien rom with stock kernel.
Cheers.

I use the same battery settings recently. I turn off GPS and Sync unless I'm using navigation. Which blur apps do you freeze? I just noticed (read on the Alien thread) On the unlock screen, hold the home button and it unlocks. I wonder if something like in pocket detection keeps the IR eye on all the time.

I just noticed (read on the Alien thread) On the unlock screen, hold the home button and it unlocks. I wonder if something like in pocket detection keeps the IR eye on all the time.

[Q] Poor battery life

I'm really disappointed by the battery life of my a500. It lasts no more than 2 days with Wifi disabled when display is off. I use it only 1 hour a day ...
This tablet is just 6 month old ... do you have the same problems ?
Do you think it could be returned under warranty ?

If I don't use mine much and I have WLAN off it lasts for about 2 weeks. So no, I do not have that issue.
Have you installed a custom ROM?
Have you checked what applications you have running in the background?
If you're running stock ROM, is it still 3.0.1 or have you updated?

That's not good
I get at least 6 hours continuous use from mine,I'd certainly take it back if you rule out something causing unusual battery drain.

I had similar problem with my a100. No matter how I had my sync settings set or what apps I removed it was still getting horrible battery life. Did a factory reset and battery life went back to how it should have been.
On my a500 however, battery has been great. I usually get 2 and a half days without turning off wifi or changing a thing, and with moderate usage. You may want to check sync settings for all of your apps.

It isn't rooted and with the last version of stock rom 3.2. I'll make a factory reset tonight and check it the battery lasts longer.
I wonder if the battery is covered by the warranty ...

Man, my iPad lasts for 2 weeks. Normal usage
Seriously, like was advised earlier.
Things that drain the battery'
Live Wallpaper
Display settings
Stupid apps like battery savers, task monitors/killers
GPS
WIFi, especially if it is constantly searching for a connection
Sync's (mail, fb, twitter, just about any social app. Google sync) all of these should be off, or set to a more reasonable time.
Apps that update automatically. Should be set to off in the app settings.
Video and games
Just because the tab is asleep, doesn't mean it stops checking these things when to time requires. Especially if you have an a501 with internal 3g.

Well, I'm also new to Android, but I got some experience. You should use an app call BetterBatteryStat (thread available here, just google that name and "xda developers").
I bet that your wifi is not off when screen off. That setting is useless. On stock 3.2.1, it works. But on both Honeylicious and Thor's ROM, wifi just stay on. Sometime, the tablet stay awake while screen off also.
I suggest using BetterBatteryStat to view detail log of your screen on time and wifi on time vs sleep time. That app also give you some idea about which app is preventing your tablet from sleeping.
Also try TitaniumBackup PRO to freeze some of the included app (like Photo Browser 3D, if you don't use it). I don't accept any app which I rarely use to have a running service (check in setting\application).

So far I have 2 days 11 hours off the charger and am at 65% remaining. This isn't just with no use... Ive used it quite a bit to web browse and check pulse / xda along with not turning wifi off, gps on(shouldnt use much battery anyway) and syncing apps set to 4-6 hours. It's not rooted and has a ton of apps loaded on it, though I try not to have any apps that look like they were made too quickly.

You were right ! A software was using the battery. After the factory reset, the battery lasts much longer. Since sunday i'm still at 77%.

Aye, that's what I thought. Be more careful what you install and get one or another task manager application so you can check for such more easily.
