[Q] 9hrs unplugged, 44min display, 3hrs run time, 40% battery left

I have been having problems with my battery life pretty much since I have had this phone. I downloaded spare parts app to give me some insight because I have also noticed several times phone seems warm even when screen has been off for some time.
As of right now today, to give an example, my phone has been unplugged for the last 10hours and I only have 44% battery left. Says display is responsible for 71% of battery use yet screen has only been on for 44min of that time (and I have the brightness turned all the way down). According to spare parts "other usage" my "running" time is cause for 35% of batter use at over 3hours.
With these things in consideration I feel that there is something that is stopping the phone from properly sleeping due to the phone being warm at times display has been off for a while and the contrast between screen on and running time. Partial wake usage doesn't show much running under it as most listed items have only a sliver of a bar showing.
Can someone please lend me some guidance on how to further troubleshoot this problem?

i mean that type of battery consumption doesnt seem irregular to me...im at close to 10 hours for the day and have 59% left.
Are you in a shaky signal area? Thats one reason my phone gets warm. especially if its a fringe area where it cant decide between a 3G signal or 4G signal.
In spare parts there is a option for partial wake lock. If something is stuck at 100%, then you know you yuo have a rogue app thats causing your phone not to sleep

But can you confirm it being normal to see 34% time running under other usage settings for spare parts? Partial wake usage as said doesn't show much keeping a wake lock going.
As for signal, not too sure, very rarely if ever see a 3g change over. Is usually at 4g and occassionally hitting edge.

WOW, you get that good of battery out of yours? that seems epic haha, i get 3-4 hours tops.. i mean i abuse it, but still..

I charge mine at night. Ran it from 7am to 12am and it was at 34%.

Yeah see...7am to 12am and 34% remaining? No way I get that.
If it werent for the results I'm posting regarding "running" percentage from spare parts other usage and the screen on time I would just accept it as a phone deemed to have bad battery life, but it seems to me like something is going on and I guess I'm looking for someone to confirm or dismiss my suspicions.
Maybe I'm also a little spoiled coming off my G2 that was rooted running CM Rom and CPU ramping/cut down which in combination gave me, under the same amount of use, a situation where I was getting home at night and still having 40-50% battery left in comparison to the 15% I commonly see now.

once some custom kernels come out that let you uv/uc/oc then i would say you can expect the same type of results..i just went on a trip with a friend who has a g2 and he was constantly crying about his battery dying, (stock), where as I only had to charge mine on average 1.5 times a day with moderate to heavy usage. I find this battery phenomenal compared to all the other android devices ive owned and tested

damn!
i charge mine every other day.. hehehe i dont abuse it or anything though.. just regular internet every few minutes or so.. i have the BETA juicedefender installed guess that helps a lot. data is off when the screen is off, set it to agressive..
here is the app hope it helps...

I noticed the same problem,i brought this phone on saturday and was very impressed with the battery until yesterday night I noticed the same thing, my phone was at 50% and I had it sleeping then I get the battery low notification 10 minutes later and the back of the phone was real hot. This can't be normal cuz I have the same apps installed from 2 days ago and I was using the phone heavily even using mobile ap and still didn't have this problem, if you guys find a solution please share it with me.

[Q] how to calibrate the battery for it to last longer??

i heard from my friend that HTC need to do battery calibration. is it true??

Don't think so. Another phone had a "calibration" routine but I haven't heard anything on this one. I tried the calibration routine from the other phone on mine and noticed no difference.

I really have a sucky battery life on htc sensation. I am trying to figure it out how I could get it to last for more than 12hours with average use...

I bought a replacement battery. http://www.amazon.com/gp/product/B0055QKZBS

While a lith-ion battery doesn't learn or have a memory, the battery does have a chip in it that needs to be calibrated. You'll need to cycle your battery from fully charged to fully discharged 3 to 5 times to calibrate this circuit. Normally a LI battery doesn't like to be fully discharged, so try to avoid doing this in everyday use. Better to give it maintenence charges. And heat is a big enemy of these batteries as well.
And seems to me 12 hours is pretty good battery life for a smart phone.

+1, very well put.
2 points.
1. There are also battery stats on the phone, which need to be built by full charge/discharge cycle.
2. Discharge phone till it's dead with no fear, battery controller shuts it down when there is some juice left. It's like reserve in your tank, it shows you have petrol for 0 miles/kilometers, but in reality there is another 5 litres sitting in the tank.

I worked in the cell phone industry for a long time. The best thing i have seen for a full charge is to regulaurly do a full charge and than turnphone off and plug back in until indicator shows full again(if it shows full already charge for half to full hour). I have always seen better results. Also if rooted wipe battery stats in advanced before flashing any radio or rom.

This may easily be true. I think I read that the battery doesn't actually like being fully charged and that most chargers shut down early because of this. Maybe your tip has something to do with that. I don't know myself how that will correllate w/ calibrating the charge circuit that I spoke of.
Google is definately your friend here.

That's a very intersting battery you got here. It has bigger capacity than the original one. Does it have the same size? Were you able to fit it in and put the original cover back? Have you noticed a noticeable improvement in battery life or is it just scam?
I don't have the tmo 4g, I have the european version, but I believe it should work too, shouldn't it?

Out of the box.... Use it till it dies completely. Charge it 100% without interruption.
I've ALWAYS had great battery life on all my devices using that method.
Do that a few times a month when it's convenient....you'll have a happy battery.
Battery and DRIVER need to be conditioned/calibrated.
I get 12-16 hours with fairly heavy use. If you want more, ya need to wait for different battery tech OR get a dumb phone.
Asking for more than 12 or so hours is just silly with a device this powerful and a display this large. I'm not someone who likes to cut the balls off my superphone to save a few hours on battery life. I'd rather get 12 hours and use this phone the way it was intended too, than get 24 hours and have silly progs like Juice Defender running. Unless you know you're gonna be lost in a forest for a few days, don't most people have access to a charger sometime during their day

Disabling the HTC Hub sync helped mine a lot.

My phone has been unplugged for 10 hours, I have 1h 17 minutes of display on time, taking 67% of battery. The rest is spread between Cell standby 11%, Wi-Fi 11%, Phone Idle 8% and Maps 3%.
It is now standing at 29% battery. I find that awful and can't believe any of you say it is normal. I have disabled HTC Hub and Sense sync and all the settings are pretty much the same as on my Galaxy S2.
On the SGS2 I manage to easily get 3 to 4 hours of screen time before the battery goes down to the thirties/twenties and a lot more heavy usage than I've managed on the Sensation. I'm on my second battery cycle and I really hope it improves because I'm very underwhelmed so far.

I found an even larger battery:

I might wanna give this one a shot, but I am a bit afraid putting battery not manufactured by htc in my phone.

Guys if bothered to look in the Accessories thread, you'd see that there is 1900 battery which some people already have and are very impressed with it.

HTC QUOTE
Charging the battery
The battery is partially charged when shipped. Before you turn on and start using HTC Sensation, it is recommended that you charge the battery. Some batteries perform best after several full charge/discharge cycles.
I spoke to a HTC REP once regarding batt life on my DHD
He advised a calibration as follows for HTC phones
Make sure fastboot is off.
1. when your battery is low, do a full charge for about 8 hours, your light should now be green. once its full, disconnected the phone
2. Fully switch off the phone(pull battery out if needed then put in). and plug in charger again for an hour, the light will actually be orange even though it was green before you turned it off.
and your screen should load the charging icon for when its turned off.
3.once it is green, turn on the phone. (put in pins or passwords etc) leave the phone on for a minute, then fully turn off again.
4. charge again for an hour and your charging indicator should be green and your battery is calibrated.!

With all due respect....how is that awful?? It's fantastic....
I think you're too caught up in the percentage number the stats page shows for battery use. It doesn't matter one bit if that graffic shows the display at 99.99%. As long as you're getting a full day out of your Sensation....isn't that all that really matters? Or am I confused by what bothers you?? Sounds to me like you're getting a full day...unless you don't sleep??
You've been unplugged for 10 hours and it seems as if you have another 2-4 hours left with that 30%.... Whats wrong with that? It's great.
This is not a Nokia 6133 It's a dual-core superphone, with a 4.3" qHD display.
Of course by the nature of the tech, amoled will be more efficient with regards to display...but as far as I can tell, the GS2 doesn't last any longer than this phone on a regular day to day basis under normal to heavy use.
I get 12-16 hours on a charge with fairly heavy use. Sync, WiFi, Calls, Web, GPS...nothing disabled or throttled.
I wouldn't get caught up with that % number in the battery stats....it's misleading....big time.
Condition the battery properly....you'll never have any battery issues...unless it's faulty.
Also people just need to be realistic with regards to battery life.... A gallon of gasoline will get you much further in a VW Bug than a Bugatti....

There is an app to calibrate your battery, but you need to be rooted. Go to www.teamroyal.net and there is instructions that you MUST follow. Read up on it now so you can be prepared for when we get root. You also ONLY want to calibrate your battery once every 4-6 weeks, and only if it needs it. Doing it too often can fry your battery.
I know this doesn't directly answer your question, but I hope it will help many once we get root.

[Q] My new, stock Charge is getting ~6 hour battery life.

I've installed the Yelp, Movies, and Amazon app, nothing else, and I'm losing around 15% an hour with light/normal usage.
I've let the battery run down to 0 and recharged completely, I've turned off gps and wifi, and still get really bad life. I live in the Bay Area and get a solid signal all of the time. There's really no excuse for it.
Please don't tell me to flash to a rom, because that's obviously not fixing the issue. Light browsing and the occasional Google Maps has my phone at <20% by the afternoon.
Battery stats just show android system and screen brightness taking up power. What's the deal?

I also constantly have at least 255 / 328mb in use even with all applications closed.
Sent from my SCH-I510 using XDA App

The mb usage is normal i noticed this on stock because of Verizon apps that run in background. As far as not using the phone and only getting 6 good hours of use. i would take to the store and ask if they could change out the battery. Hope this helps.

+1 for that, sounds like you have a defective battery.

Thats about how long my battery gets me.
And if I forget to power down my phone at night, or put it on a charger it is dead by morning no matter how much of a charge it has before I go to bed.
I have an extended battery starring me in the face and can't use it yet since I couldn't find a door and had to have one shipped from Samsung.
Hopefully the extended battery cures my issues.

I am curious as to what you guys are running. And if you go to bed with your phone on , and its dead by morning I can PROMISE you there is either something going on with your phone, or you are doing something wrong (i.e. you have your phone set to never sleep, your screen is set to maximum brightness, your are leaving your phone in desk cradle mode, etc etc etc.) But it's not the phone. May be a bad battery, but without being at your house and seeing what you are doing, I have no intelligent answer for you.

charge phone to 100%, boot into clockwork recovery and wipe your battery stats, then use the phone until you completely drain your battery until it shuts off. Then charge back up completely. This will calibrate your battery. try running a customer rom such as gummy charged or humble to see if you get bettery battery life... thousands of users have reported great battery life with both

I had same crummy battery life. I followed the calibration instructions and i went from about 5-6 hr batt life to ( right now im at almost 11hrs with 66% battery left on wifi with moderate use). Ill test tomorrow on 4g only and see how it does. I would get like 4-5 hrs before.

I am running the latest humble and my battery drops really fast. If I go into task manager and clear my RAM, I get better battery. I calibrated per the instructions as well about a week ago or so and saw no improvement. Please note that I have not been scientific about it at all.
Stopping Data obv helps a million and clearing RAM seems to help as well.
EDIT: I am recalibrating in case it was not done properly before. Hopefully it will help. I am hopeful!

I charged my battery to full, booted into clockwork recovery and wiped my battery stats.
When I rebooted my phone it shows a 73% charge?

If you are on humble 1.x then that means your battery stats were way off. Basically your battery still needs 23% more charge before its full... thus better battery life... because you had a miscalibrated battery, your phone is erroneously reporting a full charge... charge it back to 100% then discharge fully then charge all the back up

I'm on Gummy Charge GRE, but I assume the same reason?

I exchanged my battery at verizon. So far it seems better. Ive let it drain and am recharging now. I will also try uninstalling g+ if the new batt hasnt solved the problem. I will post back with an update.
Sent from my SCH-I510 using XDA App

I switched out my battery 2 days ago, and I'm still getting under 6 hours with moderate use.
Has anyone had luck with ROMs drastically improving battery life? I can't imagine it being the phone itself, but I might try exchanging it too.
EDIT: it seems like the new battery charges a bit faster. My old battery would take around a minute for one percentage gain. Can anyone comment on their charge times?

Very curious quirk On Android Open Kang Project ROM... Near Unlimited Battery!!!!

hi all...
soo after my comments over a week ago on the aokp website for this build, i decided afterall to take the plunge and update. i was on b26, so subsequently had to flash b27 and then this. everything has gone absolutely swimmingly with no issues at all so far....
HOWEVER>>>>>
I am faced with a very puzzling quirk. its by nooooo means a problem at all, infact it quite the opposite!!! let me explain.
i've started charging my phone in the evening these days for some stupid reason and then, when charged taking it off and going to bed. After getting this milestone on, my battery has been killed over night, draining to around 15%. Normally, it would drain to around 70% and be flat by the end of the day ready for charging again.
This continued for a few days when i decided to root out the cause of the massive overnite idle drain. I installed a fantastic free app called Badass Battery Monitor (which i highly recommend btw!), and over a period of a couple of days the offending app was weeded out. It was Nova Launcher. This had never happened to me before and couldn't understand it. So, as part of my diagnostics, I decided to confirm the findings by removing it and just using stock.
Over a couple of days monitoring, with exactly the same charging method, my battery levels returned to normal drainage with around 75% battery left by the morning. Fantastic. I had found the problem fixed it and got back to normal. Soooo where is the quirk i here you say!!!? lol Well......
On average, from everything i've read in forums, battery drain overnight while phone in standby is around 20/30%, so mine WAS right up there with the majority of you.
Last night, i decided to charge to full and then wipe battery stats. Which i did. Now, bare in mind here that I ONLY have the standard battery that is supplied with the Galaxy Nexus. I got up this morning, and to my utter amazement, my battery had only drained 2%
Now been incredibly realisting here based on average overnight drains, i was 100% sure that this was deffo an error. I have done everything from restarting the phone, taking the battery out, but still the level in my battery was saying the same.
As I sit here writing this, I have been streaming a radio station via wifi on the phone for the last 2 hrs, and atm my battery is telling me that it is STILL 85% full.
I am DEFFO not complaining, but i'm sure now, you can see why the hell i am so puzzled! HOW THE HELL IS THIS HAPPENING, because i can genuinely find no explanation at all for it

as a follow up, it is now more or less 5 hrs since my orginal post, and my battery is reporting that it is 75% full

Jeesh, 20 to 30 idle drain overnight? My phone drains about 3 to 5 overnight which is typically 8 hours of sleep.

Interesting quirk. Are you a heavy or a light user? It'd be nice to see how it drains after a full drain and recharge.

well, to see if what was been reported was correct, i've been an absolute heavy user today. i have wifi on, ive streamed radio via internet for around 3 hrs, ive been playing all sorts of games and watched a few youtube vids. and my battery is atm reporting 74% life left

so here i am, STILL very very puzzled..
my battery life is just going and going with no signs of running flat... have a look at these screenshots and give me an explanation as to why i suddenly have a super battery!

MAYBE you really have a super battery or your mobile is glitched and shows the battery like that due to laG?

I'm on miui and I lose 0% overnight. It just depends on the ROM, but 20-30% is ridiculous!

Your states do not seem super impressive. On most phones the screen is the biggest drain. You show 49% battery with a screen on of only 1 hour. After 33 hours you've only used your phone for 1 hour screen on. Thats VERY little.
I usually get 2.5-3 hours of screen on time for my galaxy nexus.

Thanks for the app recommendation! Been looking for something like it all day.

This will depend on ROM/Radio/Kernel user installed programs/sync etc but 2-6% is normal drain over night anyone with 20% needs to seriously look @ battery stats and work out what's causing wake locks.
Also not forgetting most phones need to bed in after a flash which can take 2-3 days before we see real battery info.

Faulty Hardware Battery drain?

Hey everyone,
I recently upgraded to android ICS 4.0.4 from 4.0.3 with the hope of the battery issue no longer an issue with my nexus s...
Though my battery drains around 1% every 2-4minutes with normal use, as in just scrolling and going through settings (not using apps), very very light use. I have factory wiped it , I have installed new roms and kernels - mixed and matched, uninstalled apps and installed apps one at a time (to see what drains), I even disabled some the high % wasting applications...
My screen dim is on the lowest, wifi is off, data is off, sync is off, gps is off, screen rotation is off, yet still no improvement, I even fully discharged my battery and re-charged it (while phone is off)- no improvement. And i also changed the CPU settings to 800max and still no improvement.
and when i'm playing a game or something it drops around 10% in ten - fifteen minutes, sometimes drops more.
When my screen is sleeping it takes around 1-2% every 1 hour-2hours, which I think is normal.
My screen is usually 45-50% Battery used by the display and backlight
Android system is usually 15%-20%
Android OS is usually 3%-10%
My battery is only about 4-5 months old, and I've always charge it when its 5-10% left, I don't let it die. I'm going to purchase a new battery to see if the problem occurs, if it does, can it be something with the phone hardware?
But any suggestion on what it is?
I've looked around on forums etc and none of the solutions have worked.

The display is going to use the most. There is no way around it. What are your average use times? If you're only losing a few % an hour idling, that's great! The only things I can think that would help is using black backgrounds whenever possible. You also have to keep in mind you're gaming with your phone and that's CPU intensive, which will cause more drain.

Yeah the display will use the most, but I remember it used to be around 30-35%, I've just been seeing how the battery is lately - just going through settings etc and it goes down every 2-3 minutes by 1%, it used to last much longer than that - 1% every ten mins. Sad thing is - I do use a black background lol to save battery and with games I hardly play them but when I do bye bye battery.
try battery callibration apk from market before you recharge your phone and no use 3g just 2g and make conservative 100/1000 the governor.

I'll try the battery calibration and see how that goes, and change the governor as well to see if any improvement.

Yesterday morning i charged it full 100%. I took it off the charger and left it on the table. It had no wifi or games running at all( at about 8 am) I leave it there all day until about 6 or so. and when i come back its down to 30% WTF IS THAT!. On my dads phone he could have 1% battery and leave it standing by all day and night and he can still turn it on without losing the last percent. Its not an iphone either. Hopefully 4.1 Jelly Bean will have some battery fix for the nexus

BetterBatteryStats. Your best friend when it comes to battery life.

Yeah. Mine isn't bad, but I also just go by my screen usage. If can't get at least 3 hours by the end of the day(which is probably 13 hours), then something is up. Note on calibration, it won't do anything. Those stats are reset once the phone is charged past 90% IIRC. On top of that, our batteries have a different way of reporting the charge. It's not the same as htcs.

I managed to get my screen down to 40ish% and my Android system is under 10% and I've been timing my battery and noticed every 4minutes exactly it still goes down. I tried calibration does nothing as you said. I'm gonna download betterbatterystats and I have cpu spy running atm...

xda will do it!

I have the same issues. 10 hours max not touching the phone at all. Stock, custom, matrix, nothing helps.
Maybe 6 hours if I start using it moderately

Similar issue here. Tried all combinations of ROMs (jb,ics,gb) and kernels (air,marmite,matr1x,lucid) to no avail. Even reverted back to stock GB ROM, radio, and bootloader. Nowhere near 6 hours talk time or 200 hours standby time. I get between 8-10 hours standby time if I'm lucky. I even tried turning the phone off overnight, with a full charge even, and when I went to turn it back on in the morning the battery was dead and I had to plug it in to turn it on.
I picked up a new battery today but the issue seems to persist. I put the new battery in at noon with 98% charge and now 2.5 hours later I'm down to 70%. I am convinced there is a hardware problem that is causing the battery to drain excessively. GSAM Battery Monitor and stock battery stats all look normal with screen using the most battery followed by Android System etc etc. Aside from the battery problem, the phone is awesome and I really don't want to have to buy a GNex when this phone is still salvageable.
So what part of this phone could drain the battery so fast with the screen off? It could be the CPU, GPU, screen digitizer perhaps?

I know you tried with your old battery, but could you try again with the new battery with your phone turned completely off? If there's a drain, then there's definitely a hardware issue.

Phone off for half hour yielded a 9% drop in battery life. I'll keep the responses in this thread only. I just realized every time I respond to a thread it gets bumped to the top of the forum!

Definitely something wrong. I don't lose anything with phone off, so something is messing up hardware wise. Did the phone get water damage?
