Is this normal???

How long does everybodys battery life last here on average? Because its starting to become a hassle for me to keep a charge on my phone... I unplug y phone every morning at 8am, on my way to work, I plug my phone up to a car charger for about 30mins, then when I'm at work around noon I plug up my phone for a hour... and yet I still manage to kill the battery by 3-4pm... the battery wont even last a full work day, even with getting juice for 1 1/2hrs... thats rediculous in my opinion, 8am-4pm = 8hrs - 1 1/2hrs charging = 6 1/2hrs battery life...
At that rate, I need 4(!!!) batteries to last a full 24hours

Strange, mine lasts about 24hrs (approx) without charging, that's with moderate web usage, games (for about 1 - 2 hours) texting all day and atleast 3 - 4 hours talk time. I'm using the battery my kaiser came with.
Although I have used an assload of tweaks in regards to battery life (turned down brightness, turned off all LED notifications, +used most of the power saving tweaks used in kaiser tweak, then again my sound + vibrations are almost always off except for when i'm sleeping or when the phone is charging, and more i can't think of)

This has been discussed before, so it's worth searching.
Battery life has many variables but if yours is un-usually short then investigate your mail settings, checking every 5 minutes obviously uses more than every 30 minutes.
Check if you have the band switching problem and the solutions for that
Are you killing running programmes, including Active Sync.
Does the phone feel warm (around battery) when it's off the charger. (a sign of an application running but possibly blocked)
So do you kill wifi after using it or if you don't use it then is it running abyway - that will kill the battery. etc etc etc
The above is not a full list but should give some starting points for searches. In general I would expect around a day of low to medium use. If you only get a couple of hours then check the things above.

How much are you using the phone for bluetooth or wifi or 3g? If not much, then you're right.
I have Alex'x WM 6.1 beta2. It's been a full work day and I still have about 75% battery. I had the stock at&t rom then tried stock HTC rom. The HTC rom had pitiful battery life. I kept it for 1 day in airplane mode and it still died in about 8 hours. The at&t rom lasted about 14 hours. Alex's may last 3 or 4 days. His WM 6.1 gives me the best battery life out of all of his or anyone's rom that I've tried.

hmm well I use an exchange server, so I cant really configure how often it checks mail... I guess it checks constantly... I'm on the phone for maybe 2-3 hrs during work, if even that, i do text alot, and use OctroTalk IM client... Thats about it, i dont play music, i dont watch movies, and I dont play games, dont use bluetooth, but I think it uses the 3G all the time, I'm not sure, it allways says 3G up in top bar...
If flashing it with a new rom can help the battery life, I might consider doing that, is there any other befits from doing so? Over all I've been pleased with the over all performance of the stock rom... except this battery issue.

2-3 hours on the phone!! and constant mail checking!! I don't know about anyone else but for this type of phone I think your battery life is probably normal. I mean that's not far off half a working day on the phone!

[Q] Battery drain issue?

Hey everyone,
I'm not sure if I have an issue with a defective Captivate or if it running as intended. That's why I've come to you guys for some insight.
Here's my scenario:
A few days ago, I decided to leave my Captivate off of the charger overnight to see how much battery I would awaken with. It was just a little experiment I thought of to see how much the battery drains while not having anything intensive to do (such as power a screen). I fully charged the Captivate to 100% before setting it on my desk and going to bed. As normally, everything was turned off except wi-fi. When I awoken the next day (8 hours of sleeping), to my surprise, my battery was down to 27%. I was shocked that something could have drained almost 70% of my battery overnight. I downloaded an app called Spare Parts as a recommendation by some people and I seen "Running 100%" which means that the phone spent no time sleeping. When I look at any partial wakelocks, it showed "Android System" as a full bar. I assume that it could be a bad app that was keeping my phone from sleeping.
I restarted the phone, battery pulled, charged up and uninstalled some apps. Everything seemed back to normal as when I checked the the running %, it was proportionate to how often I was using the phone (not at 100%). I specifically checked if the phone was sleeping and it was through some monitoring. I would use the phone for 1 minute and then let it sleep for 2 minutes and you could see that the running % went down, as it is suppose to.
I kept monitoring the running % over the course of the day and it was fine. The less I used it, the lower the % would go; the more I used it, the higher. I also monitored what kind of apps I was firing up and I specifically made it an effort to not open any apps that were out of the ordinary. If I did, I checked to see if it kept my phone from sleeping and it did not (through my same usage tests as above). However, even after my close monitoring, sometime during that day, my phone would stop sleeping once again. I could tell because my running % never lowered, no matter how long I didn't use my phone. It would keep climbing which means it no longer slept. I made sure that I didn't do anything out of the ordinary too as I used the same apps as I did when the phone was sleeping fine. I checked "Android System" and it was getting larger. The battery was around 80%.
I charged up the phone again to max and made sure that nothing was preventing my phone from sleeping. Did the tests again and running % was proportionate again and I double and tripled checked to make sure the phone slept. I then left the phone not charging again to see what would happen as I would have no interactions with the phone to open any apps or change any settings. To my surprise, my battery was down to 60% (~ 6 hours of sleeping) when I awoke. I checked the running % immediately in the morning and it was at a very high percentage. "Android System", once again, dominated the partial wakelock portion.
So what's going on here? It doesn't actually seem like I'm doing anything on the user end to prevent the phone from sleeping. How come it decides to act up all of a sudden? If it was a bad app, how come it decides to prevent sleeping all of a sudden and not before? Even if it was a bad app, I didn't even launch anything while sleeping. Does the phone decide all of a sudden to stop sleeping?
The apps I use are:
Tasker
Y5 Battery Saver
Launcher Pro Plus
Twitter
SwiftKey
NHL Gamecenter
Handcent SMS
doubleTwist
Dropbox
Does anyone have the same problem?
Any help is appreciated.

Get rid of any task killers and battery savers they do more harm then good and most developers recommend not using them, they cause battery drain. The only battery app I use is Juicedefender because it keeps the phone from connecting constantly and keeps apps from running in the backround. I set it to connect every 15 min for 1 minute to sync, I turned off all notifications because they annoy me and I don't need to be notified everytime I get an e-mail or someone posts on Twitter or FB. My battery life has improved greatly once I dumped task killer. Also, I am running a Froyo mod and my battery is amazing now and my GPS works.
If you are in an area with a weak signal this will kill your battery because your phone is constantly searching for a signal and trying to connect. Also turn off wifi if you are not near wifi this will save battery.
Also try calibrating your battery and bump charge it. Here is a link for that. http://forum.xda-developers.com/showthread.php?t=765656
The battery will improve, mine got better after a few weeks of break in. I am at 60% been unplugged since 10 am and I made plenty of calls, checked e-mails, sent e-mails, checked XDA developement all day and I have plenty of juice.

Good infos. O agree with not using task killer

Hmm, thanks for the tips but there still seems to be something lingering around in my system that doesn't allow the phone to sleep. It seems to activate all of a sudden as well without user intervention.
I again left it overnight and it drained again when I woke up. I lose significant battery overnight when I sleep. I'm thinking about just restoring to factory settings. I've only had the phone for a week so I wouldn't lose that much data. I'll monitor it from the onset once I factory reset it and see if it's a hardware defect or something that was bad in my phone.

Do you have a live wallpaper installed? Also, do you have a bunch of Widgets on your homescreen? Are you constantly synching with e mail, FB, etc? No doubt something is running all night. It's not the phone, it's something you have installed. I set mine to sleep with Juice defender at night so nothing syncs. Check your wireless bill to see how much data is being sent while you sleep. Why not charge your phone while you sleep?
Sent from my GT-I9000 using XDA App

Nope, no live wallpapers and the only widgets I have on my home screen are the LauncherPro Plus widgets, Smooth Calendar and BattStatt. The only syncing I have going on is Google Calendar and Gmail but both of those shouldn't cause the phone to not sleep.
I was thinking of using Juice Defender but I would rather just get to the root of whatever app is preventing my phone from sleeping and kill it at the root instead of finding workarounds. For all I know, my phone may not be sleeping not just overnight, but with normal use as well and it would adversely affect battery life throughout daily use. I need the piece of mind that my phone is properly sleeping.
And I have no issues with charging while I sleep, but again, I need to find the root cause. If for whatever reason I'm can't access a charger overnight in the future (such as if I sleep over at my gf's house), I want to know that I won't wake up with a dead battery in the morning.
I really appreciate the help though.
As for what I decided to do next, I actually factory restored my phone yesterday morning and so far it is working well. I did not download any apps at all to make sure that this problem didn't persist with a stock phone. If it did, I would know that it's a phone defect and not something I did. Throughout the next week, I'll be installing different apps one by one to see any one of those apps will cause my phone to not sleep. This will allow me to isolate the app. It's long and tedious, but I would go through it for better battery life. So far, it's been working as I'm already through 10 hours on my phone with moderate use and it's only at 50%. Whatever was destroying my battery before absolutely had an effect on my daily battery life as I would struggle to even get 10 hours on my phone with moderate use.

Same Here
I find your post very interesting. I have not yet used Juice defender, however, I am now more keen to battery drainage. I talked on the phone for about an hour the other day and my battery went from 100% to 40%. I find this unacceptable for a phone. Imagine taking conf. calls and conducting business in the field throughout the day. My battery would be dead in two hours without checking email
I hope you can reveal your findings to help us all.
Regards,
JROCK

Battery problem fixed using the simple technique similar to the one shared back in this thread.
I used to lose 10% per hour (or there abouts) and by 5 or 6pm needed to go on charger. At the very best with no use it dropped 3-5% in an hour.
Now its all changed...
After being off the charger for 35 min and taken 2 calls and sent a couple of txts she still read 100%.
At 5hrs 17min off the charger it is at 81% and there has been 6 calls in total and about 9 txts, plus a couple of appointments added.
Here is what they said to do and it worked...
1. Charge the phone for 8 hours, but make sure it is turned on while charging.
2. Unplug the phone, turn it off, plug it back in for 1 hour.
3. Unplug it, turn it back on for 2 minutes, then plug it back in for 1 hr.
Then unplug and enjoy the new battery life
Sounds too easy to work, but bugger me, it did!

27% is clearly abnormal.
Sometimes, I put the phone on it's charger after a pull day only using 27%.
I read somewhere on XDA that some early phones had defective screens that would only shut the backlight off and not turn off completely. Don't remember what came of that thread though.

I have a battery drain issue as well. My Captivate is 2 days old and been charging it every night. The first charge was done via the computer while transferring music over. After moderate usage (1 hour of music, browsing apps, learning how to use the phone, etc.), the battery died after 10 hours. GPS, and bluetooth was turned off. WiFi was used for maybe 20 minutes. When I got home, I charged it overnight for around 10 hours.
Today, the phone died on me after 9 hours. I rooted via z4root and applied RyanZa's latest OneClickLagFix, which both apps can be found on the market. Before that time, the battery said there was about 80% remaining. Fast forward to 6 hours later and the battery is gone. Again, moderate usage.
According to *#*#4636#*#*, my Screen On is at around 60%. A few other bars are pretty high as well, but I'm not sure how to do a screenshot on the Captivate right now. The only method I found requires using a PC. Plus, my battery is dead meaning I have to charge it overnight again.

I had an issue for the last couple of days, just figured it out earlier today. I had a corrupt thumbnail file on the external SD so my android.process.media (something like that) was constantly running.
I first realized something was wrong before I determined the battery life was bad when I noticed that my CPU was constantly at 11470-1200mhz or 975-1000 when I disabled the OC.
Unmounting the card would allow the CPU to drop to under 200 at idle so I knew it had something to do with the external SD. Turned out there was a bad file under a DCIM (camera folder), so after I deleted it, it became smooth as silk!
Of course it's still an i9000 rom so battery life is still questionable

Sorry for the hijack!

Here are yesterday's results:
Does these results look normal to you? I'm particularly concerned about the Social Hub and screen, and running. They're all higher than I expected. The brightness of the screen is set pretty low, maybe 2/10 of the brightness bar. As for Social Hub, well all I got is the Facebook widget, which is set to sync every 4 hours. Other kinds of syncing is off. GPS is off too. I don't have any battery saving type of apps yet, except for RyanZa's OCLF which includes the WiFi timeout.
I ended up charging the phone at 5% battery left. I had to sleep!

Battery issue???

I think I might have a problem with my battery, but I'm not sure. I had it on the charger for 12 hours. So the battery should be full. When I took it off the charger, the status bar indicated that it had dropped down a notch. Is this normal? I was expecting the battery indicator to be fully shaded in white.

Ok. So I restarted the phone. Now the battery indicator is showing that it's completely full. Hmmm.

This happened to me too today. I'll try a reboot...

Please remember that your battery needs some time to kick in and settle before you'll get full charges/power and correct indicators. If you just got your phone on Monday, wait about a week, and your phone should last longer and display more accurate approximation of battery life.
If it has been much past a week though, and your battery life is still significantly poor, then it may be your battery, device, or how you have the system configured.

I've commented on this a few times before, the same thing happens to me.
Its obviously a bug with the OS or something as I am now on my second HD7 and it does exactly the same.

let the phone battery drain out then let the phone charge completely with out using it. You will see a huge improvement on your battery life and the phone will charge alot quicker. That will also fix the battery indicator bug.

Ariel is right.
Remember for best optimization of any battery is when u use it 0% to 100% and then let is drain to 0% again.
i have the phone since a week with 5 charges i am not happy YET with the battery. Hope it opens up as ppl are saing.

I forced my battery dry a couple of times between charges using the HTC Flashlight app.
Run the app on maximum beam (you might have to wake it up every now and again) and the battery drains very quickly. I turned on wifi and set some music playing as well for good measure.
Then charge using the supplied charger rather than a PC USB connection. I'm not sure if that's meant to make a difference but mine charges up much faster that way.

Charging your phone through USB to PC always takes longer then using the charger

I'm getting about 15 hours of battery per charge. That's with moderate use (text messages, e-mail web browsing, a couple phone calls). This is MUCH better than when I first got my HD2. The battery would drain about 1% every 3 minutes. It was absurd. I'm pretty content with the battery life thus far. Windows Phone 7 is such a pleasure to use.

friend has an evo and he's trying to sell ot to get an hd7 lmao

I got the HTC Surround and I noticed the same thing. After coming off a full charge (the whole night) I loose what looks like 5% of the charge within the first 5 minutes. Sometimes it's after as much as replying to a text.
Hopefully the battery has to 'settle in', as others have suggested.

[Q] Am I the only one getting good battery life on this phone?

Before I bought the Vivid, I read every review that was out, even the customer reviews on AT&T's site. There was a common theme in all of them: Battery life is bad. Even the glowing reviews had "battery life" as a con or said they wished it was better.
Needless to say, my expectations weren't high. I have had HTC phones in the past and battery has never been their strong suit.
Imaging my surprise when I tell you that after a 10 hour work day, I go home with an average of 60% battery. I text throughout the day, have seven e-mail accounts syncing, widgets that pull data on my home screen, etc. I am definitely using the phone. I leave Wifi on all the time and I have LTE access wherever I go, so the LTE radio is always on.
Am I really that unique? Is anyone else getting good battery life with the Vivid? If the Skyrocket is supposed to have way better battery life, I can't imagine how long it would last compared to my Vivid, at least with my use.
Overall, very happy with this phone. Battery life is what always drove me away from Android and that is not an issue here.

I would say I unplug my phone around 7 and it gets to 10% around 7 so 12 hours ? I would say thats pretty good battery life I came from the inspire and it would die after 7-10 hours so I would say its a lot better! Though I cant wait for a cm9 or 7 rom since i was getting a full 24 hours + With that.... So im very excited to see!

I am also getting about 10 hours with heavy texting use throughout the day. I have friends overseas and we text via Whatsapp and sometimes Skype. Otherwise it would last even longer since I the screen display wouldn't always be on. I am not complaining getting 10 hours of use though since I'm coming from an HTC Aria which was about half that.

Almost as good
With the standard battery that came with the Vivid, I am getting 24-48 hours on a charge, but I don't use it as much as described above. I have WiFi on at work, but I don't do a lot of e-mailing from the phone. (I work at a desk all day, so I have e-mail on my PC.) But I do look up a lot of things. I suspect I use the phone for at least a few minutes 6-8 times during the work day and 2-3 times in the evening (with WiFi at home). I am not a heavy data plan user, partly because of WiFi access. I use Bluetooth to connect to my car's sound system during my 30-minute commutes. I usually put it into Airplane mode at night, cutting down on the battery consumption. So, I would expect to get somewhat better battery usage than someone who is on their phone much of the time.

Just out of curiosity: Why put it in airplane mode at night? Why not just plug it in to recharge?
I have a lot of days like you where I use it lightly. I have noticed that the idle drain on this phone isn't nearly as bad as past Android phones I have owned.

Yesterday I got 16 hours out of my phone. That is with me syncing three email accounts, running a live background, using data to read news articles, downloads from the android store, browsing the web, and making around 30 minutes of calls. It is much better than my cappy was. I made sure to charge the battery when I first got it all of the way before powering it on. I also have let it run down completely to cycle the battery.
Sent from my HTC PH39100 using XDA App

When my phone was stock the battery life was OK, not terrible, but not great either. With a custom ROM the battery life has increased greatly. I unplug it around 8am and when I go to charge it at night I usually have around 40% left. That is with moderate to heavy use, at least that's what I consider my use.

Failed to mention I am on the stock Rom.

I got around 17 hours last night and was only down to 70% left. Quite a bit of use too. It's actually better for me than my GS2 was.

I'm always getting 20+ hrs on my vivid with med. Use with the stock Rom my battery was pretty good but with rumraider its going on about 30 hrs with 40% left ....wow and I haven't even charged it since I flashed

I think alot of the differences in battery life have to do with how strong of a cell signal you have. The weaker the signal, the quicker the battery dies since your phone is constantly trying to stay connected. Also, if your signal is bad, than that usually means your internet data is slower too and thus it takes longer to download news, email, and web pages, thus killing your battery even further.
Although, my signal is usually at 2-3 bars, the battery seems to last much longer than I was led to believe from reading reviews. Overall, I am pretty happy with this phone.

Just a suggestion, I am getting fairly good battery left, I am on a rooted stock rom with most of the bloat ware & processes frozen thru Ti Backup, I have wifi on all day but limit sync schedule (with refresh on use enabled) I have noticed that the battery stays at 100% for a while then starts to drop off. Today running about 7.5 hours and currently have 95% charge available. I also have Juice Defender free helping out with ballanced profile enabled.
Cheers

Simple rundown:
I text fairly frequently, do a reasonable amount of web browsing (read: where I don't have access to a computer), sync 3 email accounts, check XDA and play GameBoy on the thing. Weather is on hourly autoupdate with location; news is on demand when the widget is viewed.
The only daytime charging I do is when I'm using my phone as my car's AUX input, where it is plugged on the charger (although still draining according to the battery graph).
I end the day with 52% battery life, off the charger at 7:45 AM, back on at 12:00 AM. Much better than my Captivate. Prior to root, custom ROMs and SetCPU, it would clock in at around 38%.

I totally agree with this. My office is in the basement of our building and I get fairly poor signal - maybe 1 bar but I still can access the LTE network. When I turn my wifi on, by the end of the work day, my battery is much less drained vs not having it on and my phone searching for signal from the mobile data network.
At home, I have a pretty good signal, but there's not LTE coverage yet, so the battery does last longer throughout the day.
Even on the bad days I would get home and keep it running until I plug it in before I go to bed, so that's an average of about 17 hours in total per day that it's running on battery and on average I'd have like 30-40% battery left.

I was using an iPhone 4s before I bought the Vivid and I used to go home with about the same amount of battery after a full work day. Granted, the 4s gets worse battery life than the 4 by far, but I still think it's impressive that an Android phone, especially an HTC does this well and it makes me wonder why all of these people in the reviews have been getting such bad battery life.

It all depends on what it's relative to. When I had a BB, I'd go almost 5 days between charges, but there's no comparison between a BB and a 4.5" LCD screen.

This is a key point. The big screen is a huge battery sink. The battery widget in Beautiful Widgets gives a percentage battery use for components. With mine, the display's battery usage is always at least twice as big the next nearest battery sink. It is not uncommon to see that it is using 90% of the juice. I think this explains a lot of the early complaints about battery life. We all spend hours playing with a new phone and getting it set up to our liking. That means the display is lit up for hours. That means people get lousy battery life when they first get their phone.

I was trying to see how long I could go on a single charge. Airplane mode shut down radios that might otherwise continue to run, trying to pull data I would not see while asleep. Also, I would occasionally run the battery all the way down before recharging. I generally plug it in at work, in my car or at home when it gets down around 10% remaining.

Battery life and Charging time

I've owned the Samsung Focus S now for 12 days. I came from an android bionic. I have owned Windows Phones before, the Venue Pro and the Hd7. But this is my first Samsung.
For the first few days, the battery life was fine, a full day. But this past week I find my self hard pressed to reach a full work day. I don't play music during the day nor do I have many, if any calls. Mostly SMS and internet.
I've turned off as many background tasks as acceptable, limited the number of live tiles, set brightness to auto, and check email off of push. Yet this morning I reached 20% in about 8 hours.
In addition, I find the time to charge is extremely long. It might take 4-6 hours to fully charge from 80%.
Is this normal for a Samsung?? My other windows phones, and my bionic certainly do no present the same battery problems as this one does.
Thoughts, or is this usual?

Do you have wi-fi turned on? This is a real battery burner...
My Focus S usually goes through about a day and a half before I need to recharge. That's with a few phone calls, some messages, a bit of wi-fi browsing at night, etc. Email only gets checked every hour but it's on 3 different accounts.

while I'm home WiFi is on. Away from home its off. This is normal behavior for all my phones. All of them last at least 18-24 hrs, under the same condition.
Took it back to art. They said , lets try a different battery. I'm willing to try it for now.

I just wanted to add to this as I seem to be experiencing a similar issue.
I purchased my phone at the end of Dec, it's been great.
Now, since around a week ago I've been having issues. I used to get roughly 2 days use per charge and it used to charge quickly.
Now, the phone runs hot, the battery drains in 6 hours or less, and it takes many hours to recharge.
I turned off the one app running in the background. I turned off wi-fi. It doesn't seem to help. The battery itself doesn't seem to be too hot, but it's hard to judge.

I did a factory reset, and got a new battery. I then reinstalled less than half of my existing apps. In addition I've set my display brightness to medium.
Battery life has doubled, and the charging is much quicker.
Read an article yesterday about ads in free apps eating about 35% more battery. Who knows.

Even if they're running in the background? My Focus S takes a lot of time to charge and decharges so fast. 35% is no joke.

I'm also having some kind of battery issue, I have 2 batteries and they are both 100% charged but by the end of the day one is completely dead and the other is about 20%. I use my phone a lot for music and browsing over 4g and WiFi, but I charge by battery to 100% then go to the battery saver setting and at 100% it says time remaining about 5 hours. An when I turn on battery saver it says about 6 hours. On a full charge this seems crazy. Also with the homebrew battery monitor app. It says my phone is using over 4000mV. With screen set to low and in airplane mode. This is wierd.

4000mV? I assume you mean mA? not mV? 4000mV is only 4V which is about right, your voltage shouldn't change much, perhaps +-10% tops
if you do in fact mean Amps...
4000mA is 4A an hour, your battery would be dead in about 20 min at that rate and probably in fire as well
So, lets look at this in a different way,
2 batteries, that's about 3.3Ah max, you only had about 20% left in one which is approx 330mA so lets call it an even 3A of juice burned during your day.
An Average long day at work 12 hours
that's 250mAh current draw every single hour of that 12 hour day.
250 is quite high, but normal with the screen on and high brightness an wifi, however that isn't normal if you are normal and don't sit at your phone each hour for an hour for a whole day.
Things that can send your phone off on a amp burning spree? most common one is the backlight, set it to auto, and have a dark /black theme, AMOLED is the opposite to normal LCD screens where having a white background was best,
Next up is your signal strength, low 3G signal will eat your battery (4G is worse but thankfully we don't have that)
keep battery saving on all the time, it only kicks in when it needs to but I have seen dramatic differences having it turned off even with a full battery, im not sure what it changes when its not down to low battery but it does something.
background tasks can play a part but are minimal on WP.
I have 3 accounts on push sync, wifi and Bluetooth always on (but not always connected), I use it a lot during the day including several phone calls and web browsing, I start work at 8am, finish at 7 or 8 PM and im still sitting with 50% battery...
that works out at an average of just under 70mAh. that's about the normal level id expect, its double that if I turn battery saver off (even though it wont kick in until the last hour of the day)
oh I can make it go quicker when I show off the full capability's of our screens too
