Mine is more like 7%/hr, which is totally unacceptable, I have all sync turned off, except exchange... with my HD2 running Froyo, I could do 2%/hr with the same settings.... I am still trying to figure out what's draining my battery...
I have also noticed high data usage.. I've tracked it down to T-mobile's AppPack. I've never used the program but it's constantly draining away my data... Is there a way for me to remove the app or disable it?
Thanks!

Get Watchdog from the Amazon appstore to find out what's draining your battery. I believe it costs, but it is a thoroughly useful app
Don't think we can remove carrier apps until we have root...that said, you could try adb pull, but I'm not sure whether it will have any effect. May need root for ab pull, in which case we can't get rid of carrier apps :/ sorry

On my hd2, it was like 1% on idle on android, here it seems to be more , like 3-4% on idle.

its funny how some people report 0% battery drain in 9 hours and other get 3-4% drain per hour.....
please post how many charge cycles you went through, its important.
I am personally using HD2 and battery live is amazing. and its only 1250

this has the best battery life ive ever saw. I'm in 0ma all the time the phone yesterday lasted from 530 am til 7 pm at night with a lot of text and playing games like homerunbattle 3d. If you play that game you know how much of a battery hog it is. Best battery life. Battery was soo good i barely charged it went to work with a 40% battery and it easily made it through a day with moderate texting all day!!

Gotta say... coming from a TBolt this thing is like sex in a tin can.
Idle is 1-2%/hr probably. I would get 10%+ on my TBolt at times... if not more. It was bad.

I did three full charge/discharges .
I lose about 25% in 9 hours at work mostly idle/ minimal use.

Darn it...
Seems like I'm the only person with excessive battery drain...at 7%/hr....
Just wondering, when you go into battery stats and extend the graph, does your phone stay awake when the screen is off?...
Mine seems to be awake all the time even though the screen is off.
I got Watchdog yesterday, I didn't notice any apps with high CPU usage...

Me too.. I lost about 8%/hour in 2g standby mode... Totally unacceptable comparing to my previous galaxy s...
Hope next FW update will improve it ..

today is the first time I'm having issues. Only 4 hours since charge & down to 40%. The Awake time shows as 99% of Up Time. Is that normal??? Also, anytime I look at the task manager it shows wifi calling running even though I have it shut off

I've got an Asian model sensation (ie. 3g and not 4G model ) and I find my battery isn't really calibrated properly so its hard to comment on average percentage drop per hour. I've recharged my battery 3 times already and i find the battery stays at 100 percent for around 30 minutes of constant on web browsing, then it will drop at a rate of 10 percent every half an hour with constant use and will fluctuate.
To report on a rough usage breakdown, with all background syncing disabled, I managed to get 10 hours standby before my phone dropped below 10 percent. This was with 5 hours of screen being constantly on doing mainly web browsing on 3g and one 15 minute phone call using my wireless Bluetooth handsfree.
I can report the battery life with constant usage is better than what i got with ny hd2. Running android ROM, it used to do around 3 hours of constant web browsing before the battery will fall under 15 percent. In standby my hd2 used to drop around 1% per hour, which was quite excellent.

Those are the stuff I'm talking about, it appears that one of the settings and/or app is constantly using the processor, which causes the phone to stay awake even when the screen is off... I just haven't figured out which app is causing the problem.. I am suspecting it is one of the Tmo apps.

I'm looking at a full battery life of 11 hours, 49 minutes with moderate usage (some calls, decent amount of texting, some games). I use the app/widget "Battery Left" to do its own independent assessment of battery usage and life.
So far the battery reminds me of my early days with my Nexus One -- before I had it rooted and optimized and undervolted. Once rooted and optimized, I saw a good 50% increase (at least in battery life).
If you'd like some relief right now (before we get it rooted), I recommend Juice Defender on the market. It turns off data (among other things) every now and then to save battery, and with this I can squeeze out 18+ hours with moderate usage.

how are you checking the percentage? when I looked in the settings menu, all I see is a long green battery bar, no actual numbers. Or are you all estimating from that?
I don't monitor my standby time, but I'm sitting at what looks like 40% after 13 hours of fairly moderate usage during the day, I'm impressed.

Ive been getting about 9 hours out of a full charge. Had to put my phone on the charger today at around 4 o clock because it was dead. I dont have much more info other than that. I will keep an eye on my processes over the next few days. I have only 3-4 cycles on the battery though.

To check the percentage of the battery life u have to download some battery widget in the market.. I.e smart battery monitor or battery percentage s.th like that...
Sent from my HTC Sensation Z710e using XDA App

You can also check battery level by opening Phone and dialing *#*#4636#*#* and then select Battery information.

I'm using Juice Defender and I have to say it really does the job : my Sensation lasts More than one day and a half (30min calling a day, texting, Android Market, Angry Birds...). Without the app running it would last a day (Angry Birds drains...).
Juice Defender says it is increasing battery to 1,53% and it is very close from reality.
I've been owning the phone from 24th of May.

Battery drain in standby issue?

Hi all,
My 6 days old Sensation (Vodafone contract UK) discharge a huge amount during Standby (200-350mA). I got the number via Battery Widget Pro 1.65. For the first few days I did deplete the battery fully before charging it to full. Today I have factory reset it to the original condition at around 4pm with 58% battery full. Now at 9pm, it is only 18%. During this time, I spent about 1 hour with the phone, the rest is standby. I set the widget to monitor with 1 minute interval and when looking at the log file, it can be seen that the phone consumed from 200-400mA during the standby time. Coming from HD2 with Android modded 3-8mA standby consumption, this is a huge huge dissapoinment!
Is this because of my battery or is this my phone? Should I ask for a replacement? What about you, did you see similar pattern?
Thanks,
Duong

Ditto!! So annoyed since I too am coming from HD2 where HyperDroid's consumption had dropped to a flat 2mA in standby. This is insane for a native android device. Not to mention the heating while playing games and most importantly, the front facing camera producing upside down image during fring video chats.. grrr!
Dunno what the cause OR solution is (besides switching over to a custom rom if and when the BL gets unlocked and people like pongster develop for this device)...
Overall, sexy device but disappointed with such major holes left unattended..

A little offtopic but was a battery related questions and did not wanna start a new thread so posting here -
Does anybody know of if there's any app which can get the battery percent to show in the top bar instead of the default indicator?
Thanks

something is keeping your phone awake, you need to figure out what it is.

Any ideas on how I can do that? I tried using current widget but I guess because it's not rooted, current widget showed me a log of 0mA all throughout (yeah rite! hehe)

when I figure it out myself I'll let you know.
Current things I found that killed my battery over night: VTOK & Google Latitude

I went into Settings --> About Phone --> Battery --> Battery Use and checked, and it says display is eating most of my battery.
As far as mine, I get about 12 hours of battery life with standard usage, with the display eating most of the life, so if you're saying the screen is off, you might get different results...

over my 8h sleep battery dropped like 10%, nothing special (count in : wifi on, sync with gmail, weather) guys. new phone, fresh unoptimized kernel and radio. it'll get better. my prev phone (desire) was like sh*t at beginning in relating to its current spec rom ... and btw for checkin consuption : system panel (not lite), there is monitoring and u can see which apps running again if ya shoot them, check sync-s etc. many many thing to do, hard to tell in a single post

well it certainly sounds like a part of it is specimen issue.. here's my latest experience... last few times i have let it completely discharge and then charge back while the phone was off so i dont mess with it... once 100% charged, i switched the phone on and received a call.. a 25 minute conversation ate away 15% of my battery... LOL...
then, (now it gets better)... in 2 hrs of standby, the phone was at 60% which means it lost another 15% battery in 2 hrs of "standby".. im not sure if i can even call that state a "standby" anymore...
anyways... im wondering if its worth pinning hopes on rom development on our forum or should i just return this and go with something like nexus S which, O well, I can live with... atleast it has a 3300mA batterypack available... what's the use of kickass speeds and features if i have to use a phone like a desktop..

Hey, I have pretty bad battery drain during stand by as well I recommend trying to adjust the sync accounts, esp HTC hub and how often it updates that should improve it...I have a bunch of HTC widgets set up so im suspecting that being the reason for battery drain during stand by also adjust your email update setting accordingly. Every little bit helps!

Battery gauge stuck at 100%
Another one slightly off topic - but why start another battery thread.
It is the second day with my Sensation, and since I took the phone off the charger this morning, the battery gauge has been stuck at 100%. All other apps reading the battery status (e.g. Battery Widget) show the same number. I rebooted the phone multiple times, replaced the battery - nothing - permanent 100%. Has anyone had a similar experience? Did I get a perpetuum mobile ?
BTW the readings were fine yesterday.

Yes, the rating will go downhill pretty quick after that. Mine behaves in the same way.

Thanks for the pointer.. I will surely try that and see if it makes a difference..
That being said, call me crazy but it just occurs to me that HTC should be putting in some minimal efforts to check off basic quirks like battery consumption and QC. I mean all of us are spending a buttload of money on these devices year over year and then we rely on our devs here to give us basic functionality. Back in the days the reason people joined forums was to tweak devices.. Now it almost feels like we might as well expect only the hardware for the price we pay... disappointed!
Anywho...

I fully charged the phone before I went to bed last night. Eight hours later, the battery is at 10%. Is there something wrong with the battery?

Try using the Spare Parts app to see what's really using the battery in detail.

Just got the Sensation, battery life impressions

So, after a first full charge last night, I am still at 85%. Quite good if you ask me.
It's been off the charger for about 12 hours, and saw light usage today. Screen brightness is about 35%, which used 38% of the power.
Most of the time I had the screen off. I made a couple calls and texts, and did a bit of browsing, using the phone less than an hour in total.
Coming from the G2X, this is a big improvement, because it means I'll be able to go a couple days without charging if I need to. I'm sure my battery would drop fast with heavy usage, but this is good enough for me!

had the phone for almost two days.. getting about 14 hours on regular use for me. not bad considering its bone stock. I can manage

install Cut the Rope. You'll see your battery consumption increase drastically. that game is pure evil

i found that with minimum use, and constant reception, im getting almost 20hrs before i get the standard alert.
i usually use internet and gTalk A LOT during a day, and that yields around 10hrs.
but just recently i moved offices to an area with 0 reception or 3g, and when this fone seeks networks, it KILLS the battery, from 100% to 15% warning in just a few hrs
all in all thought its got really good battery life, considering the specs

Thanks, I was looking for this game on the market...
Why does the dev didn't put it on the market ? Is there some fee ?

How do you know the screen brightness percentage? Or is it just a rough estimate?

I was hoping it would at least match my G2 considering it has a 20% larger battery but I could easily go twice as long on my G2 battery as the Sensation. And using the sensation at all really drains the battery fast. 30 minutes of GPS dropped my battery from 95% to 60%. That's just absurd.

lol i completely forgot about the GPS draining the battery, ive only used it twice and never again because its that bad thats a serious issue that hopefully gets fixed (not any time soon though, there are much more important issues at hand)

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.

I too had switch phone, but It's not a lucky one. I then bought another one for my daughter cause her phone broke and she got the lucky high quality silicon one and it's also a refurbish one, not even new. LOL!!

I have a few batteries for my dc. One on which will last me all day long while the others will last half a day with the same amount of usage. Just saying

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.

Terrible Battery Life

I don't know how everyone else is getting 3-5 hours of on screen time. When my screen is on, I lose about 1 percent every 2 minutes it seems like. When I look at the app usage, the kernel and media are sucking the life out of the battery. I am really discouraged about this battery because my G2 would easily get 3.5+ hours of on screen time. So far, I am going to be lucky to get about an hour.

Something is wrong with ur phone or u have some jacked up apps. I have got over 6 hours screen time with this phone and got over 5 with my DNA. You need to download GSAM or BEtter battery stats.

I have Gsam installed but sometimes it doesn't accurately record on screen time as it resets to 0. Also, today I unplugged my phone and the phone was thinking that the charger was still connected. As I said, Gsam reports that the Kernel is taking battery power.

Something is way wrong with your phone then.

Mine has terrible battery life
I am very much on the same page with you. I am on my 4th cycle.
Mine only last 14 hours with 3 hours of screen time. I don't understand how all these people are getting 5 to 6 hours of screen time.
I have both Better Battery Stat and GSam monitor and it shows Kernel is taking 50% and system is taking 6.2%

Just try with different kernals,good kernals would give exellent battery life

I would gladly take the battery problems to get rid of this brand new beast. It's too Frickin big.. I had g2 but sold it. Paid 700 for this att note 3...lol. straight talk on att towers to save on bills. But this thing may be the fastest latest greatest next to the new releases of '14 but I should have kept the g2...This is a tank. I'd swap for smaller phone in heartbeat. Might post cl ad

Are you in the right forum? This makes no sense.

I think it highly depends on what you're doing when screen is on. If you're playing games or using a lot of data, it can drain very quickly. If you're watching local videos or something, your battery would last a lot longer.

Im a beginner, xda said i must have 10 posts to do anything on xda so i was filling my posts..sorry friend....now i got 10 posts so im playing with n9005 rom section now

if you are rooted, install better battery stats (free on xda from the dev) to see the culprit.
clearly something is keeping the phone awake and hogging the cpu

So far today with only 10 minutes of screen on time and 45 minutes of playing a podcast through Bluetooth in my car the battery is down to 92%. This podcast was already downloaded and just playing from Dogcatcher. When I left I rebooted the phone right after pulling it off the charger. The phone is rooted and all Verizon apps are disabled. I see the android system at 40% and Google Services at 15% usage. Yesterday with only about 2 hours of screen on time I was down to 18% after 10 hours off the charger. I do not see any one app drawing power, it is always the android system it seems.
Edit: Using BetterbatteryStats I noticed that my phone has basically been awake the entire time it has been off the charger. Out of 2.5 hours it was in deep sleep for 10 minutes.

I don't get great battery life either. Nor do I get good game performance. Battery has went down 9% in less than 2 hours of idle. Just downloaded gsam the kernel use is the highest at 26+ percentage

Turning off Location Reporting made a HUGE difference to my battery life. I accidentally left my phone laying in bed next to me last night instead of plugged in, and it dropped maybe 5% over 6 hours.

I will try disabling location reporting. But I know with my Galaxy S3 I had this enabled and did not have battery issues.

I turned off location reporting and location history and am seeing better battery life today. 5hrs 47 min and 89% battery left.

My battery is confusing me. First 2 days.. 15hrs 3hrs screen on time.. 3 days after that 24+hrs with 5hrs screen on time... The past couple of days I'm back down to 14-15hrs with 1-3hrs screen on time. This is running it down to 10%
My usage isn't much different from day to day.
Power saving is now enabled and I turned off location settings. Let's see...
M8, nuff said.

What I do not understand is why my old GS3 and my co-workers HTC One M7 with location services on, do not have this battery drain problem. This should not be an issue.

Yeah, it seems to be an on and off issue. On my GNex sometimes after flashing a ROM I had to turn location reporting off to get through the day, and then after the next ROM flash I didn't.
