Battery issue?

Purchased this morning and the battery was drained... Fully charged at 5:30pm. Now at 7:30pm im as 50% with minimal use. a 4-5 hour battery life is not going to cut it.
Hopefully this is just an initial charge issue, but my vibrant never drained this fast.
Worried!

U may actually have a bad batt. But id give it a chance. Drain it down to 0. Turn it back on. Let it die again.
Then charge it while off. If it happens again youll know.

Don't worry man, it is because of the first charge.

I have done a few charge cycles completely draining it and battery life is still pretty bad...it better get a lot better than this or it is going back.
Also getting random freezes and reboots.

I've got a ton of apps and widgets installed and use Exchange push. Battery life has been just a little worse than my G2. The phone froze after I first configured it and I had to do a hard reset and rebuild it. It runs a lot better after the reset. You might want to start-over and see if it make any difference for your freezes and resets. I'm purely guessing it may be the difference between the phone configuring the SD card and reading off of one that's already configured.

Bad batt. 4 hrs is a wayyyyy bad.

Sounds like my experience too. My battery yesterday lasted me no more than 7 hours. Wooh, I was pissed. So far today though, It's been on for 14 hours and I'm only down to 25% with some medium-to-heavy emailing and texting, and a few 5 minute phone calls. I'm very impressed after this second charge. I'll drain it again tonight in hopes for a little additional life. Stick it out for another day or two, OP.

I'm really concerned because I've had my phone since Monday and have charged it at least twice a day. It's not getting any better :-( I have even froze alot of the bloatware and apps that run in the background. I can't handle 6hr battery life :-(

You mean for an exchange? Or ask for a new battery? Will they do that?

I also have serious battery issues. The battery usage is mostly consumed by cell standby and bluetooth. On my mytouch 4g at most these parameters were a few percent each. On the g2x they are like at 25% usage each. This does not appear to be normal. This is with minimal to no usage. I dont get it. Is it a software issue, there is no reason cell standby and bluetooth should be usaging so much juice with little to no use.

I have only had my phone off the charger for 6 mins and it says:

Cell standby 32%
Wifi 30%

My Vibrant is reading:

Cell Standby 3%
Thats 3 hours off charger.

Root your phone, after that install Titanium Backup from the market, and once you load titanium backup, you can actually go to Backup/Restore and find the app that you want to freeze, click on it and choose Freeze.
Once you install Titanium Backup - it will ask you for root rights - click on "yes" or "allow" (dont remember exactly which one it was" so you can provide root rights for it.

Anybody know of documentation on best way to calibrate the battery? I did 1 discharge - charge cycle... how many more do I need to do? Do they need to be back to back or can I keep it plugged in while using it today?

My battery lasts a little less than my NS or vibrant. It should at least give you 5-6 hours of HEAVY usage. I left the house yesterday at 10 and by 6 it was done. Since it's a new unit I used it heavy, plus I rely on it for scheduling and contacting clients about every 30-60min. I was also playing games on my breaks.
You probably have a bad battery.

I do seriously think that there are a lot of improvements that will come in a software update. The Cell and Wifi usage are ludicrous and it's probably a matter of getting the phone out the door with an update to follow.
This is only the second Tegra 2 phone to be released in the US.

2nd day with the G2X and the battery life isn't getting any better... If anything it's getting worse...
90% at noon and 20% at 2:40pm. Plugged in at 2:40 and now 20 minues later im back at 88%
Drains way too fast, and seems to charge even faster...
This phone is faster is every way compared to my vibrant, I just wish this wasn't true for the battery loss..

Battery draining AGAIN

So i tried what you guys suggested. I rooted the phone, bought setcpu, using anttek to freeze running services, and used the battery calibration app still NOTHING. I just woke up and my battery was at 0 before i went to sleep it was at 62%!! How can it die in idle with no running servislces wi fi off gps off BT off i mean it has to be the battery right?

I was just getting on here to rant about this. It seems that whenever I use the phone the battery gets warm and declines quickly. Lost over 40 percent battery over 2 hrs mostly playing mp3s

This may or may not be related...just something to think about. For years I've placed my phone in the top drawer of my nightstand when sleeping. What I noticed when switching to Android is if I leave syncing on it will drain my battery. My theory is...in the drawer my data signal is very week or non existent. The phone dutifully tries to sync on that weak signal...searching for signal...fails and retries...or succeeds and transfers at a snails pace. Result dead battery. I've found that disabling data before bed results in less than a five percent drop. Just my experience.
If not then I'd suggest a phone swap.
Also...Why in the world did you start another thread? If we scatter all these x is wrong with my phone posts across multiple threads it really hampers the effort to solve the problem.

I've also noticed this. In the morning my battery life is decent but by the after noon I can do light web browsing (10-20) mins in an hour and loose over 15% tmobile told me that isn't good lol I have a new battery on the way. They shipped it out yesterday we'll see if that helps. Also my battery was dead when I got my phone did anyone else get one that couldn't even power the phone on?

Yes. Like the OP, I tried the solution of the person that is so called getting 20hr battery life under medium usage. Just doesn't seem feasible at all. And its really annoying to have to cut the data off completely to keep the phone from getting warm...

If you researched the problem and tried the solutions offered, then the logical next step is to contact T-mobile for a replacement. This is an early release of a new phone; there will be defects. And you don't have to settle for a defective device/battery. I can assure you, I get battery life on par with my previous phone (8-20 hours depending on my usage)..so, bad battery life isn't a problem inherent to the phone. And my phone doesn't get warm with data usage. It sounds like you might have a defective battery or phone. If you aren't satisfied, don't settle...make 'em make it right.

I get about 5-10% battery drain overnight most nights and I am not mindfull of what apps are running or what is on. My experience obviously differs from yours. I do get great service in my bedroom where the phone is overnight. The other night I did experience a bout a 60% drop when I left the phone in my daylight basement (underground). I get crappy 2G service in my basement and it looses signal a lot. I think it adds some credibility to the searching for service slowly killing the battery. maybe try putting the phone in airplane mode before going to sleep. That should give you some indicator.

I'm now are 28 percent after 3 1/2 hrs with the display only using 13% if that..

Just curious, does your phone feel hot right now?

You might have a bad battery or something. My first g2x rebooted constantly and drained the battery and got hot.
New one goes 8am to midnight with 20% battery left, on moderate usage. And even at the 20% left i can leave it overnight and it'll still have power in the morning.

The phone is going to get warm is use because the CPU is under load and that produces heat. As long as its not overheating this is normal.
Have either of you tried the factory reset? That fixes the idle drain for most people.
Also... Your phone is going to drain battery faster while actually in use no matter what you do. The LCD and data connection are the biggest battery drain for smartphones. Until battery technology improves, there is nothing that can be done about this. But like I said try a factory reset and you should see your idle drain improve dramatically.

Were you on wifi? Because if you weren't that much drain is within the norm. Web browsing = constant data connection = more power consumption = faster battery drain.

I had 10 hours of heavy use yesterday and had 25 percent left... 2.5 of those were in airplane mode cuz I was flying from Phoenix to Atlanta but I watched a movie during the flight and had music playing the rest of the time... during my layover which was 4 hours I browsed the web, watched a stream of the Celtics vs heat for a bit, more music... I plugged back in with 25% left and had 3h20m of screen on time... this battery is freaking awesome! I had drain issues initially but they went away and now I'm golden

when i did a factory reset, my phone was getting hot until i remember about the *#*# thing and changed that to wcdma/gsm auto. then my battery life got better.

Get juice defender. Its work wonders for me and my buddies thunderbolt actually makes it through the day now

Battery Drain is mostly Cellular radio
I too am have been looking for a way to have this phone last at least 8-12 hours with normal usage, but I don't think its going to happen unless there's some major update to the radio firmware coming in 2.3 Gingerbread..
All the evidence seems to suggest two culprits... for battery drain.
- First is the 4G radio, look around at almost ALL 4G enabled phones (whether on GSM at&T Tmo or Verizon), all eat your battery, from the very beginning EVO 4g, Verizon Thunderbolt, Mytough 4G every single one of those phones has the users complaining about horrid battery life. You can confirm this by looking at the battery usage on the G2X and you'll see that the number one use is Cell Standby (that's the cellular radio) on my phone its anywhere between 35% to 60% of total power used.... on kmy nexus one it used to be the display.
-Second, Tegra 2 is more power hungry , granted its a mobile SoC but its mainly designed for Tablets and such with beefy batteries, this is the reason that the Atrix comes with a 1950MaH battery, you can try and use SetCPU to lower the speed, but I have had minimal success.
Here's a test , when you don't need your phone put it on Airplane mode, for 24hours and watch HOW LITTTLE the battery drains.. reason the cellular radio isn't on..

I agree. These battery threads are driving me nuts.
Go in the other million threads and read

The thing that is strange to me is how quickly these phones charge. It seems to go from 0% to 100% in well under an hour. Was thinking I should try charging it while off (well, screen w/ battery only).

What???? Having the phone on makes my battery drain? WTFO?!?!?!
Seriously though, I have not experienced bad battery life on this phone. Last night I left my phone off the charger, gps, wifi and wifi calling on, and when I went to bed at 1030 I had 64% battery. At 700 this morning I had 54% battery. Only a 10% drain for me overnight, or a little more than 1% per hour.
All I've done to achieve this is the following (and I realize that supposedly you no longer have to condition Li-ion batteries):
-when I got the phone, I didn't charge it but instead let the battery die completely to where I couldn't even turn the phone on.
-charged the phone overnight w/o turning it on.
-let battery die completely again.
-charged phone overnight w/o turning it on.
-let battery die completely again.
-charge and use phone normally.
I've also rooted the phone and used Ti Backup to remove most all of the bloatware except wifi calling, but otherwise it's the stock rom.
I typically get an entire day of my normal use on this phone. If I use it alot, I have to top off the battery w/ my car charger on my way home from work. This isn't unusual. I had to do this w/ the blackberrys I owned and my evo when I was on Sprint. The battery life doesn't seem any better or worse for me than any other smartphone I have owned, and it's certainly better than my evo or my wife's evo, and both of those were rockin' custom roms and uV kernels.

Battery Drain Theory explaination.

I am very hesitating posting this but this is my theory of why there is a huge different battery drain between people. I have 2 droid charge, one belonged to my wife (this is the one I play with it all the time), the other belonged to my daughter and I never look at it until a week days ago when I want to set the record straight with the battery drain issue. Both using stock 1600mah samsung battery. I Odin pit file and factory GB 2.3.6 to both, then flashed Tweakstock. Installed battery defender app on both. I installed the same exact 15 apps (included Lookout). Screen brightness set to 75%. Everytime I used one phone I do the same to the other at the same time. For example: I opened browser at the same time, navigate to the same sites for the same about of time. I mad dummy phone call, I made calls to my two sons' phone and put the 2 charge next to my mouth and talk. So they are pretty much calibrate and 99.99% identical and usage. The results is one is last 10 times (my daughter phone) than my wife's phone. Now how the hell is such a huge huge different. Max time for my wife's phone is 9 hrs and my daughter is......2days. I have a test list to play with both for 1 hrs. So let say the charge is 100%, after I played with my usage list(1hrs), the battery went down to 90% which is 10% per hrs based on my usage list. I did the list again (another 1 hrs) and I see another drop of 10%. So I concluded that my list is pretty accurate for the % drop. If I exercise the list 3 times (total of 3 hrs), 10% each hrs so total usage is 30%. I project the rest. If I do the list 9 times, total would be 9hrs and I should have 10% left after 9hrs. Well, I applied this theory to both phones and the results are unbelievable. So I concluded that the components of the phone is different, possible the cpu, gpu chip from one phone is better than the other(hardware issue not software). That would explain why some people can Overclocking to 1500 and still stable and others only stable at 1100. Some can hit 3100 quadrant score and most only can hit 2200. Here are screen shots of my daughter phone(brightness setting and all the processes, with 13+ hrs and only 70% left. Her phone should last 13 x 3= 39 hrs with 10% left. That's more than 2 days). On my wife phone(the one with ****ty battery drain), I then installed immonsy kernel, then PBJ, then undervolting it, then Jucice defender etc... nothing help. The best I can get out of this thing is maybe 2-3 hrs more. So people don't feel bad if you see pictures with 1-2 days battery life and they are real.

Gotta be right because I get decent battery life on my charge and no matter what I do to help my wife with her phone it just plain sucks.

Overclocking a phone is very similar to overclocking a computer. Some people get lucky with their silicon and their CPUs can handle massive overclocks without breaking a sweat, while some have problems going even 100mhz over their stock ratings. With this said, most processors have very similar power draws at their stock frequencies, regardless of their OC capabilities. I don't think it's the processors fault of battery drain, and also I don't think there have been any hardware revisions.

Yes, the lucky people have their "better silicon chips" inside their Charges. So If you're not in that lucky group, try to tune your phone to get at least close to Samsung factory specs for your Charge which is 11 hrs talk time for normal usage. )

Maybe your wife is using her Charge more than your daughter. Try to keep sync off and screen brightness low for the charge that drains rapidly. Try using wifi or keep mobile data off when not in use (4g eats your battery).

No one will and no one does. Samsung 11hrs talk time is if you only talk on the phone the total time is 11 hrs. It may take you 2 or 3 days to add up the total talk time not in 1 shot.
11 hrs talk time, which translated into about 5 hrs of usage (talk, internet, facebook, text etc..). Talk on the phone doesn't burn that much of power. When you put the phone against your ear, the screen turn off automatically. So, yeh! 11hrs talk time is legit.

You did not read my post clearly. Both phones were put through the same test with the exact same setup. For normal use, my daughter have the brightness up to 75%, 4G, GPS on all the time, basically she never think about the battery. On the other hand, my wife phone with auto 4G off when she turn off the screen, GPS always off, ,manually syn for all internet apps, 15 sec screen timeout vs my daughter is 1 min....and she still has plenty of battery leftover before she goes to sleep @ 11pm. It's the silicon hardware that some luck phone(my daughter is one), that you don't have to do anything and the battery last forever...

The battery itself is a huge variable.

A simple test then is to switch batteries and run the test. I have 2 batteries, one 1600 stock and a 1500 one purcased but still. Both have rather poor lifetimes. I've also replaced my phone once with no change in battery lifetime.

Nope. test them all already. I have tried with third party and stock batteries with ALL available capacity 1600,1800, 3500 and 3600. The draw rates are the same for all. they also about 6 months old. The 1600 (about little over 1 year old) is in my phone, which I used to take these pictures.

Your case, you may have a premium silicon phone and one ****ty battery, which is good, all you have to do is buy another bat. for $10.

Samsung in particular is guilty of this. They snuck in different hardware components with the WP7 Focus S without telling anyone and screwed up the Mango update rollout for Microsoft. It's up to Samsung to provide the proper drivers for their hardware.
Now with that in mind, for some reason updating to ICS on my HP Touchpad has eliminated my battery drain issue, so here's hoping the same will happen with the Charge.
Edit: And just as I said that, my Touchpad lost 20% of its charge overnight. Then it lost less than 1%/hour during the day. Sigh.

I think your first statement is correct, since I have 2 exact phone with exact SOFTWARE and one is 2 days on battery and the other is 8hrs. I hope it's software but since I did the test, I strongly believe this is hardware issue. If we still suspect software, maybe someone can download ICS and see if it still drain?

Like I said, ICS drains battery like crazy on my Touchpad. 20% overnight. A lot of Galaxy Nexus users seem to have battery issues as well. I read about a company called OpenMobile releasing a thin client that lets you install Android .apks in webOS and run Android apps in webOS cards. They've managed to port over the Dalvik VM with 95+% speed. It's pretty amazing if it works as advertised. The idea of having the battery life of webOS with the awesome apps on Android is quite exciting.

We have 2 Samusung batteries. One we get atleast 10 hours the other we are lucky to get 6 hours. That is on a stock software phone. On mine I just put Eclipse
on with the latest kernel and tweaks and I hit over 14 hours for the first time.

Anyone having crappy battery life with ICS?

Just curious is it just me or does the Skyrocket have ****tier battery life running on ICS compared to it running on Gingerbread? Anyone else having battery problems. I've been running ICS on my I727r for 2 days now and the battery life is very questionable. Probably a battery stat reset will work :S

I've found my battery life better. I haven't put down my phone since, and the battery life is on par with GB with my phone in deep sleep in my pocket. Lol
I did do a battery stat wipe and drained it and recharged it to full.

Yeah, my battery went out pretty damn quick yesterday, but that could be because I've been fussing with my phone more than normal.

The first day of using ics my battery life was okay. The second day my battery life sucked. Why? Because I set up Facebook. Battery manager showed 10% use and I hadn't even checked it. Its the bloat!

Same, my i727r battery life is horrible since i flashed ICS.
I have noticed that my android system is pulling a lot of juice compared to GB. I made some changes today like freeze all the bloat + installed UCLC4 modem. And wiped battery stats + complete drain and discharge of the battery. Lets see if it get better after a few cycles.

My battery seems a lot better! Way way way better. 25 minutes of web and its still full!

Battery has been much better for me with ICS.
Freezing tons of bloat helps..

My battery life has been horrible on ICS but when I look at the battery thing, Face Unlock used 35% of my batter (when my batter was 5% left) o-o it takes THAT much?

My battery life is absolutely amazing with ICS.
I have the stock rom debloated completely, and a lot of junk is disabled. Coupled with turning off auto brightness and leaving data off when i don't use it, the battery just chugs along.
This morning I got in my car at 7 AM, started playing music full blast through the stereo for an hour. Got to class, played some temple run, approximately a half hour worth. 30 texts or so, one 1 minute phone call. (data was off the entire time, it keeps facebook from butting in from behind) My battery has literally only gone down 10%, and it's 1 PM
I'm in love.

Seems fine here, I usually have it plugged in but today am testing it without. The couple charge blips are from when I had to get some files off of it.
I froze a bunch of the AT&T bloatware, have had Wi-fi, BT, GPS enabled the entire time. Moderate/light use... I've attached some screens.
I'm running http://forum.xda-developers.com/showthread.php?t=1567817 with the flashable ICS modem.

My battery has been horrible but it's only been a day for me and my signal has been fluctuating a lot on day one. It's stabilized now so we'll see after a few days of use. But right now it is horrible.

It seems mine is doing worse.
But I have been adding a lot of stuff since this is my first time rooting.
I am about to get a battery depleted(at 12% right now) and reset the battery statistics and install the OEM battery.

I thought there was a lot of debating over deleting the battery stats, i remember an article from a google programmer saying that it actually decreases battery performance...i personally stopped doing it a year ago and noticed a better batter experience, most of the time bad battery comes from a bad flash or apps that run in the backround and use location services

My battery life was horrible with ICS so im back to GB. At work with phone in pocket for 2hrs and was already down to 75% off killing battery and charging it fully next day. When I got home after 8hrs of work already at 50% and thats when its in sleep mode. Using it I would drain 1% every couple minutes definitly bloat. Might try new debloated ones but kinda skeptical since GB gives me amazing battery life.

Once the kernel source drops custom kernels will make all you guys stop crying your all used to optimized stuff not samsucks stuff lol give it time

Well condiering I have never reset them and did this first and only flash of the ICS leak, I'm hoping it helps out. We'll see what happens.
I have Juicedefender turning everything off while sleeping(set widgetlocker to deinied so when locked, widget locker stays active to be ready, and juicedefender see's that and turns off data)
On my 2100mAh nexus battery I barely got over a day(was getting 36-40 hours on GB)
Either way, I have two batteries so I'll deal with it until either an official ICS release or a new rom with better battery performance comes around.

I also have the nexus battery. Def have less battery life with this version of ics .
It could be the algorithm the use. At the start of the day is slowly draws down. As the day goes on it seems to drain faster

Actually, I have been having the Best battery life to date. I will post my list of APK's that I removed. I don't do FB or anything like that, so not sure if that is affecting it. Also, in a non LTE area. on the UCLA3 kernel, I was absolutely getting horrid battery life.

I live in an LTE area and I am getting almost a full day of use. Never got that with GB. I keep wanting to charge it, but I dont have to.
I do have Juice Defender running though, and it disables my data in 15 or 30 min intervals when the screen is locked. And I have SetCPU which limits the CPU to a max of 384 when the screen is locked.

Battery discharge isn't a linear function my friend.

Battery life problems.

Hello, I'm currently running cm 9, however the battery life is just awful
When the phone is on sleep it loses like 1 percent every 5-10 minutes
I am using an extended battery as well, please tell me what to do I was on GB before and the battery was outstanding, I could go on one charge the whole day with heavy usage, now i dont think I can make it through the day with light usage on this
thank you
EDIT: This could be a sleep problem, because when the device is on, the battery is normal

If you flashed the Feb 27 cm9 you should flash proton kernel so you can watch videos. Battery life isn't as good as gb no matter what you do. Also give it some time to settle in. It takes more than a couple hours.

alright thank you... I just flashed the newest version of cm9 a few hours ago, I was flashing a bunch of roms and this one seemed the best... do you know how to force a device into deep sleep cause that seems to be the problem i believe

OK I was just on 20 percent, then i rebooted my phone, and now im on 2 percent... im seriously considering going back to gb

Sounds more like a battery thing? With CM9.? + Proton I'm getting at least a day* with light use. Maybe a bad app or combo of apps? What does BBS say is eating the charge?
* - I say at least a day because I can't not use it for that long.

just the screen and the android system... very interesting thing though is happening
I'm running a bunch of quadrants to get the battery down to 0, and the battery is all the way down to 1%, however it's been on 1% for like 6 quadrant tests... maybe its just a problem with the indicator, however another indicator also says it's at 1%... very interesting

If you are on CM9, I suggest you flash Hefe or Proton.
I use Hefe because according to the posts being made it puts your phone into deep sleep, which means longer battery life.

Definitely a battery problem. This happens to me on one of my batteries but not on another. Time to buy a new one. I haven't tested it fully but it does appear to be just a display issue. Sometimes the bad battery will make the phone display 1% but it will still act as if it had way more than 1% charge left. I haven't done any testing on that regard but that's what it appears to do.

I don't believe it to be a battery problem, because I've been on GB with absolutely no problems and exceptional battery... I just upgraded to ics not long ago, and the battery life instantly screwed up

Have you set the cpu governor to anything silly like performance?
Have you let it charge up fully at least once?
Search xda for "better battery stats" app, use it to see if you're getting deep sleep.

Flash hefe over release 8 and youll have a little better battery. Proton doesnt deep sleep
Sent from my SGH-T959V using Tapatalk 2

Proton DOES deep sleep. That was one of its major features.
Certain scheduler/governor combinations work better on different kernels, though. If the specific one you like most sleeps better on Hefe, great. If the one you like does best on Proton, great. Just be aware that most issues are either physical or user-inflicted...
In this case, your battery is almost certainly dying. The variance in power over a reboot is a definite tell that your battery is probably swollen. If you can spin it on a table, the cells are starting to die. This does not mean you can't keep using it, but it does mean that your battery life will be irregular. It also means that you'll have significantly "higher" battery levels if you reboot the phone with external power connected, but the battery will discharge very quickly if it hasn't actually reached whatever level it believes it should be at.
