Battery Usage Report not reliable - HTC Inspire 4G

I know there have been some discussions about battery, but I think what I'm about to share has not been explicitly mentioned.
It is about Live Wallpaper. If you read most forums/posts, there are people asking if Live Wallpaper uses a lot of battery. Then, most end with a response that says, "If you look at battery usage report, it is usually only 2% or so, so it shouldn't be a problem."
Well, I found that it is not true at all. I was using Live Wallpaper, and my phone's battery usage report said 2%, 4%, etc. So, I figured it really wasn't a problem. But, just out of curiosity, I tested my battery without Live Wallpaper, and I found out that it makes a HUGE difference. I mean, really HUGE.
With Live Wallpaper, By the end of the day (12~14hours), my battery was down to like 30% or less.
But, without Live Wallpaper, it lasts MUCH longer. For example, today, it's been 11 hours so far, and my battery is still at aroud 65% full. That's twice as much. The only difference I made was Live Wallpaper.
I'm sure it depends on which Live Wallpaper you use too, but don't be deceived by the battery usage report. It's not a reliable source to use when examining true battery usage.

well i thought the general opinion around was that live wallpapers DO in fact use significant battery. i've always avoided them regardless.

Touch Pro & Battery life dispute!

It has been quite interesting to watch all those threads for the above topic which of course lead to nowhere so far.
I would not exclude myself of the dispute, however we need to think of the issue in a practical methodology and thus conclude what the facts would lead to.
There has been many complaints and unhappy people about the battery life in Touch Pro and many other models. Just a simple question I ask; What would be an acceptable avarage battery life with one full charge? I am sure responses will vary coz there is no standard expectation nor a universal benchmark for this issue!
Whatever the vendor guarantees as an operating expectency measured in hours, is more or less what you gonna get although many wont accept it, but this is it, you gotta live with it!
There are 1000s of users with 10000s of applications and conditions that have high expectations, but they all get even results, so why complain?
What I am trying to highlight is if many have expressed their dissatisfaction of the battery life, I just say; who's right & who's not? Do we all expect to have the same results? My device may run for 3 days with one charge and couple of calls throughout, others may have tougher uses and expect a battery to last for 7 days in a row with just one single charge?
Just think about it and have a collective understanding.

ya made a wise statement here.....couldn't agree more ...
yep, 2nd that
a wm device drains a lot more battery than other phones because it does sooo much more. and its not device specific either
maybe if someone creat app to change CPU to 200- 300 and so on if don`t used for heavy apps will incress battery life. In the PSP there is app like this ans when I used it only for play music set procesor to 100 Mhz
I have had the phone for a week now. I like it. I like how pretty much everything works. I don't see much of any problem but the battery life. Why didn't they put a larger battery in. My Mogul has a 1650 in it. Yesterday morning the phone had a complete charge. I went to worship and used it very little in the morning. By noon time where I showed the phone off to a friend who is thinking of getting one, the phone charge was down below 50%. It should have been 70 or 80% and no less, IMHO.
I've posted this link before on a different section.
http://www.hardwarezone.com.au/reviews/view.php?id=2726&cid=24&pg=6
I get nearly 4 hours as well if I use mine full on. Tried watching a full length movie and my battery meter shows ~50% afterwards.
I thought OP might be interested in seeing this review.
I don't think it's really an issue of someone being right or wrong. I think 24 hours is just a particular limit for cellphones, and once it dips below that we start to worry about the next time we'll be near a power plug. After all, these are devices that we use on a daily basis.
If the batteries lasted 2-3 days, then it wouldn't be a big deal if we forgot to charge once in a while (late night, canceled flight, forgot charger, etc). But as it is, people are having trouble pushing it past 24 hours even under modrate usage, which means if they miss even one charge cycle, they're dead in the water the next day.
Of course usage is a different issue; but if you start modifying your usage habits in an effort to prolong battery life, that's still the same problem. You could turn off 3G, stop mail checking, always close background apps, etc; but without any of those features you might as well use a regular dumbphone -- no point in getting a device like the Touch Pro in the first place.
Last week we went on a short holiday. Both my girlfriend and I have a TP running RomeOS v1.13. She has a GSM prepaid card and I have a GSM/3G/H card.
Her battery lasted 4 working days occasionally calling home to check on the kids and sending a few SMS messages.
I used my phone to check email and LIVE messenger. My battery lasted no more than 20 hours.
So if you by a full featured phone, just to use it as a basic phone you won't complain that much I think. If like me you want to use a full set of features pffffffff... And if you don't mind I would like to keep it at that
My first serious WM phone (I don't count the ridiculous HP 6315) was the Samsung i730. I am a very heavy user and I got used to charging it in he car & carrying a spare battery in my pocket. If it made it to 6PM without going dead I was happy.
The Touch Pro has the same screaming 528 mhz processor speed, plus a vga screen. If it makes it to the end of the day, then I'll be more than happy (haven't received mine yet, it's in the mail). There's always a trade off for speed and resolution. I'd rather carry an extra battery than have a frustratingly slow processor.
I've had my TP for a week now and with a pretty heavy usage, my messenger is almost always on, some internet browsing and a little bit of monkey island on scummvm, my battery lasts 2 days. I can live with that.

Which Messenger are you using? I'm trying to find a good Google Talk client that won't drain my battery.
The battery should be expected to last a day. Past that, would be nice, but I do not feel it is necessary...
If the phone won't even last me a day (and "a day" for me is 14-16 hours at school and work) then it really isn't going to work for me. I hate trying to search for 5-10 minutes to have the phone plugged in during the middle of the day to try to extend the battery to make it just past that 12 hour mark for me.
The CDMA Touch Pro doesn't seem to do too well. Sitting idle, it had about 40% battery after 14 hours, but then dropped extremely quickly after that... I must have sent 10-12 texts and was in a call for about 10 minutes the entire day, no programs running in the background, only the cell radio turned on.

I agree with you 100% - except here is the problem: the vendor guarantees (well, doesn't "guarantee", but no vendor really "guarantees") a battery life that is absolutely not right.
On the Touch Pro, Sprint says the phone has a standby of 406 hours - that's 16 days! Incredibly misleading, and in my estimation definitely not accurate. That's the biggest problem I have with the whole battery issue.
Also, in comparison, my Mogul was suppose to have 340 hours of standby and 30% less talk time - but my Mogul lasted a LOT longer than this phone. I could talk, surf, play games, and have it still last longer than this phone. That doesn't make any sense.

Alright, alright, alright! Let's not mention the biggest and silliest gimmick PPC vendors made us believe in specially those of high-end CPU ones
I might have been worng in choosing "guarantee", but who says! When you read "Stand-by" I am sure that the vendor wouldn't in gods name mean "with any GSM/CDMA network"! I mean just think about't!! Why in heavens name would they shoot themselves in the foot by committing such a thing
I could defy anyone who would tell me that "Stand by" is a standard by itself! Haven't you read "The above are subject to network and phone usage" in phone specs?
In addition to the above, network signal strength matters and is very fundemental to extend/shorten battery life too!
Whether or not the battery was of 1300mAh or 1600mAh, it is all the CPU power management and I am pretty sure that Qualcomm is unlike the Intel XScale as the olden memories remind me of
Like most of you rightly said; change your habit and the battery life will change accordingly.
Just a last lil thought, why isn't there a quick options made available in the market for a higher amperage batteries? If one would care about the total gram units, then I recommend to live with the supplied battery.
Let's all cherish the memory of the HTC Universal, that baby was a hot long-lusty orgasmic son of gun device ever was.
I feel the term "standby time" has been used loosely, never in working with wireless phones have I found a machine that is capable of being on this long without being charged. Notice the "up to" that is always there on these kinds of stats too. What does up to mean? Probably something to do with turning off all the radios so the phone can't actually do anything, it might as well be off.
No matter what you do, computers require a lot of power to maintain themselves in any sort of "on" state. If there are any background processes happening (i.e. cellular radio sniffing for incoming calls and sms) you are really only burning power at a rate less than that of radios + screen.
Phones consume more power than phones did even a few years ago, hell they consume a lot more. Does anyone remember first-gen digital phones? 2 hours battery life, talk/standby, didn't make a difference. In fact the batteries used in mobile phones have changed (lion/nicad etc) probably a lot less than the manufacturers' ability to use less power to get the job done.
You can always strap on a bigger battery, but then you have a bigger phone, making it even HEAVIER!
Ultimately, as others have posted before me, that when you buy a touch pro, it is because you are looking for all the functionality that the machine entails. If you use all of the functions at the same time you are burning the candle at both ends. We buy a phone with a gps, bluetooth, wifi, 3g, vga screen qwerty, 3.2mp camera, etc because we need (or want) all of these features at the same time. When you are using the gps while having bluetooth on visible, screen full bright, wifi still on and music playing, don't be surprised your battery won't get you through the day.
I think that the general consensus here is that typically we should be able to get about 1 day out of the pro. Any more, we are lucky, any less, you either have a defective unit or you may have unrealistic expectations of the device.
That being said, after a few weeks go by and you find yourself actually being able to put the damn phone down for a while, battery life will seem longer too
My experience:
I've come from an XScale phone, which runs Linux and doesn't have 10% of what Pro does (like GPS, wifi, 3G, SDHC support, VGA screen, G sensor, light sensor, etc.) and even without all that it doesn't have a great battery life. I had to recharge it everyday sometimes, because I had pretty heavy use (especially A2DP audio).
With the Pro I can do that and much more and still get at least a full day of battery, which for me is good enough.
Tell me one device that has the same size does everything the Pro does with better battery life.
Unfortunately we are still to see better batteries, which I've read a lot about, especially that nanowire technology which supposedly makes them 10x better, but until then there isn't much we can do. So I don't think it's fair to blame a manufacturer, HTC or not, for poor battery life, because IMHO they did an impressive job on making such a small device with so much power, and still manage a full day of moderate use.
I find that TF3D is a real power hog too. Although I really like the interface, I am trying a run with SPB Mobile Shell instead
It is 3:30PM EST now, I unplugged the phone after a solid charge at 8PM, immediately changing to SPBMS.
It is now about 20 hours later and I have 63% remaining, that is a 37% discharge. I have been using the phone normally for the purpose of this experiment and normally the phone would be at about 30% remaining with tf3d.
There is a thread about this here
http://forum.xda-developers.com/showthread.php?t=441767
Hi All,
I'm wondering if besides the GPS, WiFi, 3G and Bluetooth.... the application processor, running at 528MHZ is not a cause for this poor battery life time?
Adrian
The reasons why we read many different opinions is that people use phones in very different ways. I can usually cope with the short battery life but sometimes it is really annoying. It just needs a few hours in a bad coverage area and the battery drains completely. Or an unexpected need for TomTom to make the battery go flat before I get back home in the evening. I used an HTC P3600 (which is a very similar phone from a featureset point of view) for two years and I never had to worry not to listen to music at the airport or on a plane because I wouldn't be able to use the phone after landing. Instead I have had this problem already twice with the Pro... this terrible battery life is really spoiling my user experience with this phone.

Well, as I said in my previous post, discounting the hardware keyboard and the fact that it wasn't a very attractive phone my old HTC P3600 used to do exactly the same things with a much longer battery life.

Battery Life Claims vs. Reality

I stopped by an AT&T corporate store to get a hands on with the Captivate. The salesperson there tried to tell me that the standby time on the device was 15 days if you kept apps from running by downloading an app killer. I asked if he really meant 15 days if no radios were running. He said "nope, 15 days is pretty easy".
Really, folks... what is reality here? Is it similar to other smartphones, where a day with moderate use is reasonable?
There is no way the phone will last 15 days in standby even with a good task killer. How can the sales rep tell you this if he only had the phone in store for 2 days?
That's a very good point... but he was very sure of his claim. I pulled out the "I'm very skeptical" response and walked away. Oh well, looks like once again, truth is in the internets somewhere, not in someone who should know such things.
Another element to this is whether an upgrade to 2.2 will increase battery life. I work away from any ability to charge and really need a phone to hold up all day.

Well, my N1 holds charge for about 1 day with moderate use. As soon as I play with the GPS and google's built in nav system I get maybe 4 hours worth of usage. Another issue I have with my N1 is that my car charger cannot keep up with the drain, so even plugged into the charger the battery percentage is decreasing. Sure hope the Captivate is better in that respect.
Froyo did increase battery life a bit but it is not earth shattering. The advantage of this phone is the larger capacity battery and hopefully a less power hungry samsung processor than the qualcom snapdragon.
I am sure within the next few days we will have some folks with more concrete consumption estimates.
i don't know... while the 15 day claim is a bit much, mine was fine with heavy usage all day yesterday on the half charge that it came with from AT&T... given that, i think that it should last 2-4 days easily with only light-moderate usage.
My battery lasts me all day. It's just marginally worse than my 3GS I think... My 3GS always had extra at the end whereas my Captivate seems to run out when I'm going to bed.
So... It lasts all day. That's really all that matters to me.
My battery has not been able to make it through the day. Don't know why yet. I have my email accounts set to 30 minute sync schedule, have Wi-Fi and bluetooth off. Don't know what is going on. Still researching. Will see how it goes for a week. Might be a bad battery.
i find that dark backgrounds help. Also keep unecessary things off and dl an app killa. I had a new captivate today at 10am and with its half charge and heavy usage it lasted me till 6
by heavy usage i mean constant surfing and dling shiz. I didnt use gps wifi or play a movie. also played that free mario game for bout an hour.
After about 11.5 - 12 hours of very light browsing (maybe like 1/2 hour 3g surfing, no calls, all apps killed with task killer every once in awhile) with Bluetooth and Wifi off I am at 68% left. This is with auto brightness.
I'd say if you don't do anything you might be able to get 3-4 days out of it. According to my battery stats 78% of all my battery usage has been the screen. Keep that thing off / or low brightness and you are going in the right direction.
i bet by standby att means the phone being not used and turned off for like 4 days lol

By dark, he means a background that has a lot of black in it. This is really helpful because the Super AMOLED screen on this phone turns off power to pixels that are black, so basically that part of the screen isn't using any power. A black background is almost like turning the screen off.

this, thanks for clarifying.
note: it further helps if you apply a static one.
I was able to listen to music for 6 hours at work, show off my phone (I only showed it directly to one co-worker - I had 5 other guys come to check it out after he told them about it lol!), did some light surfing, downloaded a few apps and generally fiddled around with the phone and ended up at 43% battery. Not great, but not terrible either. Screen was the big killer here. GPS and WiFi off except to test Layar.
We'll see if battery life improves, but it enough to make it through one day easily for me. Forget to charge it and it'll be flat early into the next day though. I'm a bit disappointed, considering benchmarks on the Galaxy S came up with nearly 8 hours of constant video playback. I think they had brightness at 50% and I kept setting mine to max to show off the screen and then forgetting to set it back, so that could be part of it. I was definitely expecting more though. I'm clearly not the most demanding user here, so I was hoping to potentially eek out two days of usage (just in case I forget to charge it).
One of the reasons I went with the Captivate instead of waiting for the Epic is that the form factor seems to be a bit more amenable to adding an extended battery. Hopefully we'll start to see some 2500mAh or even 3Ah batteries show up - even if it means getting a new backcover. THAT should just about do it

Also the Super AMOLED Screen sucks alot less Juice as well...
My friend has the Vibrant and has had it for about 4 days. He is a power-user like me, and he said with his task killer, he can run the phone for 2 days on a full charge. This is outstanding for a smart phone... I ordered my Captivate today, should be here on Wednesday so I'll also put this to the test!
better battery life is coming once devs hop aboard. Also, your phone will need training over the next few days so it can only get better from here for you. I also recommend just leaving brightness on auto detect. You wont have to play with it as much and forget it on super bright.
Some more tips:
idk if you guys like haptic feedback but i think its annoying as all hell. Turn it off to save an iota of battery.
Also tone responses for menu clicks? ANNOYINNGG turn that shiz off for a squirt of juice.
Lastly, unless you live by your email, turn sync off and only sync manually when ur curious about it.
I wonder about some of the widgets. I have Weather And Toggle Widget (which I prefer over Beautiful Widget), and have it set to update the weather every 30 minutes. Wonder if that's too often. The weather in Iowa can be very unpredictable and change quickly, but I'm inside all day so it doesn't really matter. I guess it's just eye-candy mostly.
I also wonder how WATW compares to BW in terms of battery consumption.
I turned haptic off (I agree, it was annoying). I turned the tones off, though I doubt that will affect battery life. I wish I could keep the tones for dialer and kill it for the keyboard.
EDIT: I keep reading about this idea that you train your battery (or device) to your usage, but I'm not sure that I understand/buy it. I could see perhaps something to do with the memory effect if these batteries are susceptible to it, but this idea of "training" it strikes me as very odd. Does Android have some kind of battery optimization algorithm that adjusts services based on your usage or something?
from what i understand, calculating battery life is like a guessing game. calibrating your device by letting it drain out and then fully charging it and draining it out again completely gives your phone an idea of just how long it can last on a single charge. Until you do a few cycles like this it will incorrectly display batter life percentage giving the user a false sense of security or panic. There may be more to it that has to do with the actual battery itself but idk the rest of the details.
and 30 min updates is a bit much lol. u should update like once a day and manually refresh if you need to know b4 u go out.
I'm getting very good battery life on my phone. As good as any iphone I've had and better than any of my windows mobile phones before that. I don't have any widgets constantly pulling down data though and only have my google account syncing contacts and calendars and an exchange account running.

Analyzing Battery Usage

Hey folks,
So I'm shooting for good battery life as my #1 concern with my phone. At stock speeds with a good kernal and a debloated rom, the performance is up there and the phone snaps along just fine for my tastes.
However, I'd like to try and maximize my battery life.
Upon a fellow member's recommendation, I installed 'CurrentWidget' and now have the current draw updating directly on my homescreen.
BUT, I don't really know what I'm looking for as far as analyzing what is using what, and what are good numbers.
The phone updated the widget once when the screen was off and it was 40mA.
When the screen is on it goes from somewhere around 250 up to over 700.
Anyone have any tidbits of info for me? Let's get a discussion going.
Thanks!
damon
40 mA is normal for a TBolt with the screen off, that's what most of them I've seen run at. Over 700 during usage seems a little high, were you doing something demanding? And check your brightness settings too.
If your ROM has Spare Parts installed, you can go into Spare Parts -> Battery History and check various usage statistics with the drop down menu. Particularly useful here is Partial wake usage, since that tells you what's draining your battery while the screen is off.
There are threads all over the place on battery life, so you should definitely search for them.
34mA is about what i saw during idle time for 2 thunderbolts. but that is very high. other android phones like my nexus one and desire get 4-5mA over night during idle time, connected to wifi. so something is wrong with the TB stock ROM, but not much can be done unless you switch to cyanogen ROM or something like that.
also the other utility to use along with current widget is system panel, paid version, because it gives you a complete breakdown of every app cpu usage and what is hitting your device so you can troubleshoot and track your battery drain. that app is invaluable.
Mine also hovers between 30 and 50 on idle for two TBolts. I agree with the above that with a properly optimized rom we should be around 10 which will boost battery life quite a bit.
I use Battery Monitor Widget. I like it better than current and it keeps a nice history.
System Panel paid is also very very nice.

Battery use Display: live wallpaper uses less than just a normal wallpaper??

i had normal wallpaper with that display uses was 53%
but now with live wall paper on it reduced to 42% in one hour ??
confused
which one uses more battery simple wallpaper or live wallpaper ??

live is using more CPU !
maybe your stock background is more "light" and the live darker so the Samoled can handle the darker much better
and you cant compare 2 wallpapers cause of that thing in the settings! you did not used the two wallpars the equal time! so maybe you woke your phone with live lesser then with normal wallpaer up !

That just means the screen is responsible for a smaller percentage of the total battery loss, compared to everything else. My screen often eats about 50% of the battery. That could either mean that the screen is a battery hog, or that everything else on the phone is crazy efficient. Turn airplane mode on, auto brightness off, and screen timeout to 30 minutes. Then check the actual battery drop with each wallpaper after the phone sits idle for a half hour.
AMOLED screen
I'm pretty sure its the colour. As you may be aware, with AMOLED technology, darker colours on screen use less battery because unlike LCDs, the light is only generated where needed instead of being generated everwhere and blocked out where its not need. It also makes for much better contrast. So try experimenting with darker wallpapers if you want to get more battery life. I think the difference would be quite small though.
I'm surprised that after so much time since android has been released, people still don't know how the built in battery monitor works. The percentage shown there equals 100% if you add all of them. That shows the total energy that the phone uses and displays which apps consume it and how much of it. If it displays 100% for the android OS (let's just say, that it would display only this), it means that the only thing which consumes energy on your phone is the OS, nothing else. That doesn't mean that the battery usage is 100%, it would killl the phone in a few seconds from full charge.
So if you had 53% for the display before applying the live wallpaper and 46% after, it means that there is a new process in the phone that eats voltage.
Those values show what uses the most energy from your current total usage, it doesn't mean that the display eats 46% of your battery. The live wallpaper probably has 15% or so, but it has a much bigger impact on the battery then 15%.
Hi,
just a question just on that topic:
I got the I9023 with SLCD and i want to optimize my battery life.
What is a good % of power usage for the display? Mine is 54% and i think it's quite high, is it normal?
Is there anything i can do? I just got the phone 2 days ago, so i'm using it more often than usally (well it's new, i'm not familiar with android.) but in a week or so, when i'm used to the phone, i want to get the maximum battery life out of it.
Data:
Android 2.3.6
I9023XXKF1
Kernel
2.6.35.7-gf5f63ef
[email protected] #1
Build Nr.
GRK39F
If anyone knows, how i can get a better battery life and overall performance, pls tell me, i really don't know where to start, i just downloaded the most common apps i needed, or wanted to use and used go launcher ex to get the touchwiz 4 theme on the phone, as i am more familiar with that (i had bada system before, hated it (well atleast i liked touchwiz )
Thanks a lot in advance guys!

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
EDIT: neva mind... found it... everybody's allwoed 1 dumb post once in a while
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.
