[Q] For those who get 24+ hrs of battery usage - HTC Sensation

Battery drainage has been a major frustration for me with my phone. The frustration stems from the many variables associated with battery drainage. For the most part the terrible battery drainage started after flashing the modified ROMs. I believe the stock ROM was respectable when it came to battery drainage.
I am not ignorant to flashing ROMs. I have tried everything to figure out this battery problem; everything to keeping stock kernals, to battery calibration (delete battery stats), to battery bump charging, to matching radio files with RILs, to limiting data syncing, charge cycles etc.
But I am noticing that some of you are able to get good battery usage from a single charge with these modified ROMs. With that said, I want to cut the variables down and see what those folks who are getting over a day's worth of battery usage from a single charge are doing. The best indicator for battery usage to limit variables would be the battery usage standby rate with data network on.
I am not getting any better than 8%/hour on standby for any of these ROMs. That is crap. I wake up in the morning after 8 hours and there is only ~35% battery left. Unacceptable. I figure no more than 10% should be lost in 8 hours of standby.
So for those who have good battery usage, please answer the following questions so that we can eliminate all the variables.
1. What is your standby battery drainage rate?
2. What version phone do you have (TMoUS or EUR)?
3. Clockwork Recovery version?
4. What ROM are you using?
4. What Radio and RILs are you using?
5. How many charge cycles are you doing after the battery calibration and before you are getting the good standby rate?
6. Are you using any battery saving applications?
Please help if you can. Everyone seems to emphasize speed and performance but battery life is number one priority for any phone in my opinion.
Thanks

I'm currently running the P3D Neon ROM. I was having the same issues you are having due to flashing a new ROM jsut about every day. The big thing I noticed is that the longer I stayed with the one ROM the better my battery was. But as I'm sure you already know that no matter what a smartphone is a battery hog anyway.

By the way have you tried this, I am using it and love it !

I've had my phone a week and am using stock Rom. I've S-Off, Root and install backup. Overnite, the battery only goes down 5%
If I were u, I'd get Android Assistant from the Market and check that all apps are closed. Check ur start-up apps and clear ur cache before u shut down ur phone.

More than likely, there are apps that are not allowing the phone to sleep when the screen is off. CPUstats will show you how long your phone has been in deep sleep, as well as your CPU clock speed.
Here is what I would try out:
1-Get CPUstats.
2-Turn off the screen for the night
3-Check to see how long the phone was in deep sleep mode. It should have been for awhile if not, you have a rogue app that is bothering your phone while it sleeps.
To check your standby current:
So far, we cannot accurately see what it is. I dont know of any app that can for our phones. I do know that the values I see cannot be correct, otherwise my phone wouldnt be lasting long.
1-Write down your current battery capacity in mA/Hrs.
2-Write down the time that you put your phone into sleep.
3-Leave it off for an hour.
4-Wake it up and check the new battery capacity.
An Example:
I started with 1900mA/Hr.
I let it sleep for 1 hour.
I found that after an hour, I was down to 1850mA/Hr. That is 50mA gone, over 1 hour time. So my standby current was 50mA/Hrs.
Now this is only a crude way of judging whether or not your phone is behaving. Since the battery apps update capacity every 5 mins or so, you may not be right on the money, but you WILL know if something is BAD. Calculating 50mA +/- 20mA means the phone is likely sleeping as it should. Calculating 300mA+/- 20mA means something is USING your phone without your permission.
Youll need to find out if some apps are syncing (or trying to sync) while it sleeps. Or, your phone may be trying to improve your signal strength.

The anker battery will help but it is not solving the problem. We need to be getting around 1-2%/hour standby drain like some of you guys are getting.

Foyo update...Battery life shortened ?

Has anyone noticed their battery life seems shorter since the update ? I installed the official froyo update last night and it seems I'm running out of juice much quicker than before.
At first mine ran down faster. I ran it all the way down. Charged it. And ran it all the way down again and charged. It seems back to normal.
I didn't have any issues. Maybe you changed something else as well? Could always try a few recharge cycles and see if it stabilizes..
I was running the leaked 2.2 and I flashed to official 2.2. My battery life is almost double what it was. I can't complain one bit about battery life, although I have other gripes with the official Froyo release.
I'm with icepop on this one.. I was running the stock rogers rom pre-update and now with the official rogers 2.2 I'm getting at least double the use before having to charge again.
I'm having battery issues with the new stock Froyo. I lose a huge amount of juce when in standby. I thought I may have my widgets updating too often so I charged it up and put it into airplane mode last night. The phone lost about 1% per hour in airplane mode. IDK what is normal but that seems like a lot to me. I didn't have any apps running, except my alarm was set for the morning.
I have SystemPanel installed and my cpu load NEVER goes below 10 percent, even in airplane mode. I suspect this is a large part of the issue. In app history, system and system processes are always on the top of the list and are around 3% each. IDK what controls this or how to lower it. I would love some feedback from someone else with SystemPanel just to see how our numbers compare. Overall the battery life I'm experiencing is pretty terrible and a buddy of mine's Fascinate has much better battery life (hence something must be wrong somewhere). He and I were skiing all day over the weekend and when we got back to our cars, my phone was half dead and his had lost almost zero juice. This displeases me.
mine's was better actually. but i didnt stayon it for long
My initial results with 2.2 were very bad (10% drop per hour when idling). I reset the phone back to 2.1 then re-installed 2.2. This did not help. Now I did this again (2.1 then 2.2) but this time I have not re-installed my apps and have not rooted (yet). So far, battery life seems to be normal. I suspect that some of my applications might mis-behave when installed on 2.2. I am planning to add them slowly and watch the battery.
Not here, seems the same to me
Mine is terrible ! I don't know what it might have been on 2.1 as I upgraded fairly quickly. Essentially I charge all night and then disconnect from power at 6:30am and then by 4:30pm I'm out of juice (phone shuts off). Any ideas here? I'm not running anything extravegant (email only) and hardly make any calls.
Whenever you flash to a new ROM, wait for at least a week of normal usage before you judge the battery life. The reason is simple, your battery stats are reset after ROM flash and your new OS needs time to learn how your battery drains before it can give you accurate readings.
If you can't wait for that long, you need follow the battery calibration thread to force a manual calibration of the battery.
I'll give it a week and see how it is then. Definitely is draining much quicker now though. I think It acted similiarly when I first got the phone as well. If I recall correctly the batter life sucked when I first got it, but then a week or so seemed to get much better.
I did the manual battery recalibration (let it die, charge while off, turn on and bump charge...etc). Last night I lost about 2.5% of battery per hour while in standby. This seems improved since calibration but its still pretty terrible IMHO. Is this in line with the amount of drain other are getting or am I draining more than usual?

Running stock since purchasing the Captivate back in August, and so far battery life actually seems to be routinely as good if not better than 2.1. I must admit I didn't use my phone a huge amount yesterday (except for about an hour plus of downloading a bunch of wallpapers off Zedge for some ungodly reason lol), and after 18 hours of the phone being on I was still over 50% battery life left. 2.5% in standby doesn't sound like all is well - you must have something running in the background or similar issue. I have a live background, sync 5 e-mail accounts (granted, only one of those is every 15 minutes - the others are every thirty minutes, every hour, and once a day on two of them), and with light use I am getting over 40 hours with 2.2 so far (about in line with 2.1, but seems maybe just a little better). Heavy use I am dropping more like to the 12 - 18 hour mark (heavy use for me means the screen on more than off, actively playing games or using apps, large amounts of texting, etc. Solid game playing I haven't figured out a drain yet, but on some games it seems like I can drop almost the whole battery in close to 10 hours). At your rate of 2.5% per hour in standby you would only make it forty hours without even using the phone. I have been using mine just a little this morning (FB check, logging in to one of the desktops at work remotely to make some changes, live background running, WiFi sleep policy is set to when screen is off, but to be honest that is about it) and I haven't moved off the 100% mark yet and the phone has been unplugged over an hour and a half.
All that said though, as other users have stated you might want to give it a little more time for the system to recalibrate the battery usage. I would definitely check your processor usage though regularly to see if anything seems 'off'. One thing that caused me problems was that my SNS service would be running but then would get stuck in a pattern of 'Restarting' - would drain my battery rapidly.
It has been said that bettery drain is not linear. First 5% goes real fast. So, you need to judget the average over a day of use, not first hour or so. I'm still in first week of ROM flashing. So I can't confirm anything yet.

[Q] Disappointed with the battery life... :(

Hi folks - this is the first thread I have started, hence requesting the non-noobs to go easy on me... (this forum is a scary-kind-of-cool)
I mustered up the courage to install Infused 1.5.0 on my stock... the instructions were superb and everything went great... really enjoying the improved speed and looks. But my battery life has degraded. It has been more than a week since I flashed my phone - and it is only getting worse. Now I have read a lot about how Infused is getting great battery life for some folks... and i have gone through those threads, trying to figure out what I am doing wrong. This is my typical usage profile
1) I put the phone on charging before I go to sleep... when I wake up (around 7 AM) it is fully charged.
2) I quickly check overnight messages, finish the daily ablutions, and 30 min later when I check the phone it is already at 95%.
3) By 10 AM, I have made a few long phone calls (no bluetooth) (totalling 60-90 minutes) - and the battery is down to 75%
4) At work I use a bluetooth A2DP headset - maybe 30-40 min of calls and by 12 I am at 50%.
5) More calls in the afternoon, intermitted mail checking and sometimes 30-40 minutes of music streaming on my bluetooth headset - and by 6 PM my phone is down to critical level 12-15%.
This is in now way the same experience that others are having with the Infused ROM and with the Infuse phone in general.
Other points:
6) I run Juice Defender... (don't know if it helps)
7) My screen brightness is just a few notches over 0%
8) My data is always on - except when I am using Wifi of course
9) I turn bluetooth off when I am not using it
So that's the story guys... and I would eternally grateful if the awesome folks out here can help me figure out what I am doing wrong... or there is some logic behind the sad battery life of what is otherwise the best phone that I have ever owned.
It depends how long Infused has been running on your system. After about 3 days I noticed my phone was adjusting to the ROM and the battery life improved significantly. Aside from that, try this trick. Drain your battery next to nothing and then charge all the way. Do this a couple of times. Not quite sure about the logistics but it seems to work. Another thing that has improved my battery life is to make sure I don't have background apps running. You can check this by going into apps > manage apps > and then running. Sometimes Media Hub will begin a background process and that eats up a whopping 8 MBs alone. Force close these pointless background apps and you should see an improvement there as well.
have you conditioned the battery and reset battery stats?

Thanks popesmasseuse (you really aren't are you?)... the ROM has been running now for a week... gets worse rather than better. I do typically wait for my battery to drain completely before I charge it... but when I do have to do it at 7 PM - then I can never charge it fully, before I have to start using it again. I wonder if the fact that my phone goes through "micro charges" is a reason for my declining battery life...
Will check the running apps... and see if closing them improves things... thanks!
Fact: Installing a ROM greatly improves battery life... Try it....
Turn of GPS and Bluetooth when not in use.
Same here I uninstalled media hub... period... just useless...
Phone calls are a pretty heavy battery drain. Sounds like you're in call for hours each day. Most people don't talk on the phone more than a few minutes a day. Poor signal will also significantly reduce your battery life... how many bars you usually have at work?
My battery life got better the longer I had the infused ROM. But personally I only talk on the phone maybe a total of an hour each day, but I am constantly using internet and youtube, and if I have spare time I'm using my Kindle app to read some books. I keep my GPS, sync, and wifi on all day long and my brightness all the way up (I just can't stand a dim screen lol) and by the time I got home today my battery was at 40%, which I am perfectly fine with.

Ah...the man himself.
Yes I talk a lot on the phone - nature of the job. 3 hours minimum in a day. Signal at home is terrible - 15% strength... that could be the reason why the battery runs dry after the morning routine. Any way to offset that?
At work signal is great. But in office I also tend to use my desk phone more...

Read the thread in my sig.
Never use task killers.
For me, battery life on phones gets good after about 2 weeks or so.
With light to medium use I can easily go for 2+ days.
Consider not streaming music through Bluetooth. Also don't auto sync stuff every 15 mins. If you can use Gmail they use Push notification. I'm on my phone all day literally and I make it home with some battery left. BTW connect to a Wi-Fi when ever possible, 3g data streaming will kill your battery quick.

has anyone tried this method?
It's a Lithium-Ion battery which means it does NOT respond to "conditioning".
"Reconditioning a battery involves completely discharging the energy from a battery then recharging the
battery. Li-Ion batteries do not require reconditioning to maintain good battery performance since Li-Ion
does not have a memory effect. It is necessary to complete drain and then recharge a Li-Ion battery in
order to determine its current capacity level, but that is not the same thing as reconditioning the battery. Li-
Ion batteries do not have a condition that needs to be reconditioned." lxe.com

Keiht's tutorial is effectively a technique called "bump charging" for putting that last extra percent or two of charge into a battery. However - with Li-Ion batteries, charging like this will SEVERELY reduce their charge cycle lifetime.
The only thing that "calibration" should affect is how your device reports battery charge level, NOT actual power usage. You should get the same total battery life whether your device is "calibrated" or not, with the exception possibly of the device shutting off prematurely because it thinks the battery is lower than it really is.

I would have to agree with you. I followed his directions as i was having horrible battery issues after going to 1.5.0 and it seems to have helped the reporting as far as I can tell. I think the big problem and it is only a guess is how the phone is reporting the battery condition not actual battery left. In any event I am running JD and the longer I run with 1.5.0 the battery seems to be lasting a lot longer but I have ti disable most everything which hobbles the phones best features to get that battery life still searching for the perfect solution.

Current widget (and yes, I searched first)

Does anyone know what's up with Current Widget? It's constantly reporting very high idle-draw values that I KNOW aren't correct. It's always reporting draws of anywhere from 70-400mah. If those numbers were accurate, my phone would be dead within hours but I'm getting very good battery life so they can't be right.
Every idle drain app I've tried does this, on every rom I've tried. I've read posts where people say they're getting 2-4mah drain, so is it just MY phone that's funky or is there some other way to measure idle drain?

maybe you could try " battery calibration " from market and calibrate your battery... might do the trick..
and it's impossible to get 2 or 4 mah even in sleep mode on the sensation...
i use battery monitor widget and info are correct , on temperature and on Mah.. around 200 - 215 mah in standby mod..
It seems all the current draw apps are not working correctly on the Sensation at the moment.
You could estimate the idle current by noting your current battery capacity, putting the phone into sleep (screen off), and then leaving it that way (nothing waking it) for some amount of time. Then, after you have noted the time in sleep, check to see what the new capacity of the battery is.
Example:
Starting battery capacity: 1900mA/Hr
Sleep time: 1Hr
New battery capacity: 1850mA/Hr
Difference in capacity is 50mA, time is 1 Hr, so you used 50mA/Hr while in sleep. This will work out better for longer sleep times. It cant be 100% accurate since the reported capacity may not be 100% correct at any given time. (The monitor updates every minute or so)
This will, however, let you know whether or not you are seeing a reasonable current draw in sleep. It just wont be useful for knowing the EXACT value. At least you will know whether or not you are seeing low current draw or high.

I think it's got something to do with dual core. It was designed for single core.

Going nuts!! Battery...

Have to charge almost twice a day... I believe it happened after latest 1.45.531.1 update....
Disabled all animation, got auto adjust for display, disabled all what I could.. Still gives me 12 -16 hours on standby only....NOT even using the phone!!!!
Does anyone have something like that??? Or there is some remedy I skipped?
Sorry if I repeat someone's question.
Running full stock, HTC battery.
Thanks in advance!!
Tester.
PS. Recently exchanged the phone.... First one R.I.P......died completely, didn't even charge.
Is there a chance they swapped a refurbished one on me??? How to find out???
can you provide a screenshot of the battery usage graph? also, have you tried getting an aftermarket, bigger battery such as the anker?
I was the same way as you. I checked my battery graph, and standby was using something like 80% of the battery with almost everything turned off. By the time I got home from work I would need to charge it immediately. I bought one of the Anker batteries on Amazon for $15 bucks or so, and I'm now getting about 2 days for a charge. I don't know what it was with my battery, because it sounds like my experience wasn't typical, but I didn't really feel like going through HTC when I could just pay the $15.
I'm with ya...
This phone was running PERFECT prior to the HTC update. Now I'm having a plethora amount of problems, including the battery. For example, prior to the update I would get 13-16 hours on HEAVY usage... Moderate usage? Try a day or day in a half. Now take today for example, I unplugged my phone a little before 7am and I had 20 something percent 4 hours later.
I'm telling you, that HTC update really messed this phone up IMO.
Thanks, guys!!
Will try to get Anker battery, I believe it's 1900 mAh.
But again something running on the background with that update. We'll see.
I'll try to get the graph, maybe someone'll get some sense of it...
Much appreciated,
Tester.
here are the battery stats...
Display..........74%
Cell standby...13%
Phone idle......11%
Voice calls......2%
THAT'S IT!!! Nothing else is running...... SUX...
Still gives 12 - 16 hours of life on almost idle......
I hate to say it,but if you're battery's dying a lot faster after an update,a bigger battery won't help much.
I'd be getting in touch with HTC and ask them what the heck is going on.
Really annoyed with the battery performance. I checked and only display is using 90% of battery. Tried everything to reduce it but no change.

I've had the same issue since the update. My battery drains at a ridiculous rate. I've become really frustrated with the phone since. I rooted it and flashed a custom ROM in hopes of solving the problem but it's the same deal.
I've confirmed it's not the battery either since I've got another one I've tried and only get the same results. Even with Juice Defender running I get nowhere as great a battery life as I did before the update
I'm doing decent 8hrs 20,mins on batt. With 40% left mostly text and internet browsing

Try clicking the graph at the top of the screen it will give you another screen that shows awake/screen time etc. Is your phone going to sleep when you screen turns off?
I was having the same problem and realized that some app was keeping my phone awake even though the screen was off. I uninstalled 80% of the crap I had installed and now my phone sleeps like it should and battery lasts amazingly long time.

How can you tell if your phone is going to sleep when you lock the screen? What is a good method for this? And if I find it its not sleeping when it should, is there a way to find the culprit easily?

Click on the graph in battery stats, it should show awake time and screen on. If your awake time is constant when the screen on time isn't, then chances are you've got an bad app somewhere preventing the phone from sleeping
my battery life was plain **** on 2.3.3., device was running hot all the time (=waste of energy), charging took ridiculous 4h+! When I took it off at the charger around 23:00 the battery was dead at 14:00 the next day with most time being idle!
Since my update to 2.3.4 things got so much better. charging takes around 2h and battery finally lasted a whole day and had 40% juice left in the evening.
Since I got my 2 Ankers+charger for 20$, battery life is crazy now. Been on one charge for 2d2h and still had 16% left. Pushmail on, wifi on (cellular data only when not at home), brigthness at 100%, taking video, pictues and some navigation, messaging and phonecalls. Oh yeah and a few minutes of flashlight use
I would say between slight and medium use.
If 2.3.4 worsened your batterylife, contact HTC or your vendor.
I now replaced the battery at 16% with the other Anker because I still need to do my 5 charge cycles on that one to calibrate it.
Here's an example of the graph. At the bottom you can see awake and screen on time. I pulled phone of charger last night, did some browsing, then ran for an hour with music playing in the background (you can see the small green bar on awake even when screen is off). After I surfed a little and left it off the charger when I went to bed. The phone is properly sleeping when the screen is off and almost 16 hours and still have 62%.
Before I uninstalled the apps, the awake time was solid green across the screen.
Anker battery worked wonders on my device. Before I would have to throw it on the charger after lunch as I like to go for a beer after work and the stock battery would never make it that far... Now when I get home from the bar I still have ~30% battery. Anker battery FTW!
flash a custom rom and u will go gaga over ur battery life. definitely works for me. on standby overnight drain 0-1%.
I found out that if you don't have strong signal at your location your battery drains pretty fast that's why I always connect my phone to WiFi at my apartment where my phone looses signal sometimes. now I lose just 1-2% of power during a night.
Sorry to hear about your battery troubles. A couple days ago I rooted and switched to "Android Revolution HD 3.0.4" and my battery life seems pretty solid. I wasn't having battery life issues prior to this though.
I'm currently in the process of calibrating the battery:
- drain it mostly
- turn off
- plug it in overnight while still off
- in the morning unplug, wait 15 minutes, replug for a few hours; do this ONLY ONCE or you may damage the battery
- power on, immediately go to recovery, advanced, reset battery stats
- start normally
- drain battery until it shuts down; a continuous stress test or stability test app is probably ideal
- once it shuts off, turn it on again to double-check that it's dead; it should only come on for a second or two
- while off, plug in and allow to fully charge; no fooling around with plugging/unplugging, just normal
- calibration complete!
I think you can follow a similar procedure (minus clearing battery stats) to refresh the battery calibration even without rooting/custom recovery. I've read the effectiveness is similar. The phone just needs to be retaught what "full" and "empty" mean, all in one charge cycle. If you calibrate it wrong you could have issues with it shutting off while still reading ~15% battery life.
Anyway, as I said, I'm in the process of doing this. Currently I'm in the "drain it" phase... with my screen at maximum brightness (remaining on), overclocked to 1.5 ghz, I've been running "StabilityTest" (from market) for one hour and fifteen minutes. It stresses both cores as well as the RAM. At this time, my battery is at around 30-40% or so, and it's getting really hot! The phone's temperature is reading as 54.8 degrees!
Also, yesterday I used the GPS for about 4 hours before it died, this was prior to any calibration attempt. I think this is within typical battery life considering that the screen stays on.
TL;DR: Maybe you just need to try a custom rom or recalibrate your battery. Miscalibrated battery can be caused by flashing/updating a rom, I imagine even when it's an OTA. Sense is crippling your phone anyway, you might as well give it a try IMHO.
get yourself an anker battery..I havent charged my phone since the day before and now i have 20% left! heavy usage

Battery drains unusually fast while screen off?

Last night before I went to sleep the battery was around 94% after an hour of solid use from a full charge.
I woke up today about 9 hours later and the battery was at 55%. It's been about two hours since then and I'm all the way down to 30% with only about 20-30 minutes of solid use.
What's up with that? Any ideas as to what I can do to fix it?

-Battery calibration, basically drain to 0%, then back to 100% on single charge.
-Try custom rom
-Might be radio, try flashing different found in development thread
-app or widget installed recently?
-look in battery use under settings menu to find what is eating up battery consumption, in your case likely something via cpu consumption (ie not display use)
What is your current set-up?
Check out battery drain threads in general section.
I'm working on battery calibration right now, this is my first day with the phone (I got it about 24hrs ago, actually). I'm gonna let it die then charge it to full.
I'm on a custom ROM right now, QuickWiz v1.0.3. It's blazing fast, no cool features though. I miss my CM7 that I had on my Inspire but the CM7 alpha was a bit too buggy for me.
I'll check into flashing some other radios in a few and I suppose it could be the weather widget I installed. I'll check that and see if it's syncing too often or something.
That's the funniest part. I just looked and I have 1h51m of screen on time (Mostly around 35% brightness, give or take a bit) and it's taking the majority of my battery at 31%. Right under it is Dolphin Browser HD at 13%. I might just swap to another browser, any recommendations? Last under that is the Android OS at 12%, then everything else is under 10% - Cell Standby, Speed Test, Market, then down to 5% which shouldn't matter.
are you using a cpu governor such as system tuner or setCpu? if you are OC'd, id suggest also cpuSpy to determine how long your device is in each state(clock speed)
I am OC'd. i have a setcpu profile for screen off that cuts it down to ~54/400MHz when the screen is off, set to conservative as well.
Hmm, if I had to guess, check the radio. I've had the problem before. As far as browsers go, I like Dolphin HD, just make sure you completely exit out of it when not using, otherwise it can be a resource hog on idle. Since you haven't had the phone long, reflash your rom of choice too if you get such a drive, that has fixed battery issues for me also.
I love my battery life using TPC's ROM with DaG's kernal. I'm also using TPC's CPU zip to govern and set CPU speeds 192-1782MZ without the use of third party programs. Some see zero battery loss when idle over night. I lose maybe 5%.

I installed a new radio with 8% battery left before I went to a birthday dinner. That 8% lasted me through light to moderate use at the dinner for about an hour and a half before, and I got back with 3% remaining.
I also froze a bunch of bloatware which could have also been taxing my battery. I'll wait another few days of use before I flash any other ROM's/Radios to make sure I'm not happy with the battery life and past that, I guess I'll just have to return it for a new battery or an LG Nitro HD instead, if the dev scene starts to pop up for that phone.
Can you link me directly to the CPU script zip?
what was the radio???
I just got the QuickWIz a few days ago and Im having the same battery drain problem while screens off.. its getting on my nerves
