Best way to "train" battery

I thought we were done with the battery training but always my biggest issues with Android phones was the piss poor way the battery life is ... to be very frank.
3hrs since full charge i am down a battery meter and 50% has been used with the screen which has hardly been one i haven't made a single call as of yet.. are we in line again for another battery killer?

The 50% screen use is actually fairly normal. You have a lithium-ion battery, so there shouldn't be any learning to be done, but nevertheless, heres a link to get you started:
[Guide] Everything you wanted to know about Li-Ion batteries but were afraid to ask!

I just finished one full cycle with 13 hours run time and just under 5 for screen time. Xda, web, few pics, a little video, some nav. Everything on but bluetooth, everything syncing at stock settings.
Not much in the way of calls as that is a feature I tend to neglect.
Overall seemed fine with me.

Okay fair enough, the only thing i keep on is BT for my car but that was using just 2% idle and connected to the car for a 45min trip to work.
I turned off HTC Sense Facebook

I've been up for 6hours with minimal use till now and I'm two notches down with display being the most. I just train mine to get through a day cause I plug it in every night.

I guess I just don't feel that I've used mine enough to warrant now being at 50% made some calls yes maybe 35min total and some playing around on the UI but I don't know. Just the battery has ALWAYS to me been an issue with Android phones... just want to get away from the iPhone 4 so bad.

Mine is at 70% after being run down to zero/recharged to 100. It's been unplugged for 17.5 hours and has had what I consider moderate use -- running gmail and exchange sync, a few calls, good amount of texting and surfing. Have killed all the widgets except for beautiful widgets time/battery/weather.
f I did the same on my captivate it would be down in the 50s by now. I think this exhibits great battery life for a phone that is so large.
Run it down till it completely runs out and turns off/charge to 100%. Do two cycles and you'll see what the capacity is.

I have to "break in" the battery too

it makes me laugh everytime I read one of these threads. LOL. There is no such thing.

Training a battery? Umm, sure. Ok.
Like how kernels have to "settle"?

If you are rooted, you can erase the battery stats through recovery. I just did that earlier today and now I'm running the phone completely dead. Then i'll charge it all the way and let it drain again. Usually does the trick for me.

Battery stats for those on custom ROMs

Im trying to convince myself to get the Inspire and sell my atrix.
The last thing that is making me reluctant is the battery. I consitantly get between 30 and 40 hours between charges on my atrix with 3 to 4 hours of screen time. I know i wont get that with an Inspire, but im wondering what kind of stats people are seeing who are running custom ROMs. With my capitvate i saw a nearly DOUBLE battery life effect between stock and a custom rom. im hoping there are similar results on the inspire.
for those on custom roms, im looking to see how many hours you get between charges. ideally, how many hours between charges, with how many hours of screen time, wifi, blue tooth, etc. and im also interested in seeing the battery life of those who are OC/UV.

Someones gotta have info for me!

Inspire battery usage....sucks!
If your main concern is BATTERY USAGE, then DO NOT get an Inspire.
No matter what ROM or other MODS made to an Ispire, it is accepted by all that have one, that the Inspire has very low battery uptime, especially when compared to other platforms.
Stay with your ATRIX for long battery usage and uptime. - Glenn

I just swapped my Atrix for the Inspire this past Sunday, and i can tell you first hand you're not gonna get the same battery results you did with the Atrix. Personally, I don't need to get 20-40 hours of battery life from a phone. Don't get me wrong, it is nice, but I don't need it. I just want to get at least 8 hours (while I'm at work) from a battery and I'm fine. However, I do have my charger with me just in case and i also have a car charger.
I rooted my Inspire Sunday night and flashed the stock rooted rom and couldn't be happier. I got about 13 hours out of the battery yesterday while I was at work and I used it under normal circumstances..calling, texts and lots of fb checking etc. Oh, and I didn't have any overclocking, underclocking, themes or nothing...just the rooted the stock rom.
The inspire is a lot more smooth also when compared to the Atrix. I was all for the Atrix last week. But after actually having the Inspire....its the Inspire FTW!

Its not my main concern. Just the Las thing I'm considering. A lot if other things about the inspire are appealing. Just looking for round about numbers.
Can I get 12 hours out of itwith 2 to 3 hours of screen time? That might be enough for me........If can get more than that, then I would def be sold.
Of course all this would be expected only when all aetttings on phone for Max bat life applied

Speak for yourself. My Inspire lasts me the day with a ton of juice left over. I'm not a super heavy user, but I will have sometimes 60-70% battery life when I go to bed on light use days. On heavier use days I'm still at 30-40% when I go to bed. Unless you are watching youtube videos or something for hours on end, battery life is fine I think.

To extend battery life I adjusted my screen brightness back to 30% with no auto adjust, seemed to help battery life quite a bit and did not make much difference in how the screen looked. Today I am trying auto brightness, but using power saver to switch to lower screen brightness when the battery hits 40%--I'm at 7 hours and the battery is still at 70%. Honestly, I don't think a person could even watch a movie on a flight, for example, the screen draw on the battery is that bad. If I keep the phone, I will have to get another battery.

I get 22-24 hours with light average use, about 14 hours of moderate use. CM7, nothing special done or flashed.

I was replying to the OP's original statment regarding his Atrix battery time in reference to the Insire's battery time:
OP said......The last thing that is making me reluctant is the battery. I consitantly get between 30 and 40 hours between charges on my atrix with 3 to 4 hours of screen time.
Even with your light usage, I am doubtful that you get anywhere close to the OP's "30 and 40 hours between charges on my atrix with 3 to 4 hours of screen time". - Glenn

well i guess i will just find out.
impulse buyer here. immediatly ran out and purchased an inspire after making this thread.

You're going to LOVE the inspire (even with the lower battery time). I have no doubt you will be throwing rocks at ATRIX users in no time!! - Glenn

Lol ur right so far. Smooth, fast, solid. Just the smoothness and screen size is enough to win me over

My results are based on percentage of time versus overall time, based on an average 8h work day.
Stock rom:
at the end of 8h I had an average of 55% left
Revolution HD 4 Beta 2:
at the end of 8h I had an average of 35% left
Stock rom rooted and bloat removed, HSPDA enabled:
only have one data point and it looks good so far. I had 75% left with the same average use as the other roms above. Why this one is so much better I don't know.
Also the stock rom came with the stock Radio 06.04.06_M but with the root downgrade and then custom rom to Rev HD4 B2 I had to upgrade the Radio to one that was suggested, which is 06.03.24_M2.
Also, one thing that I noted which was also seen on my Nexus One is that when I use the GPS my car charger is not able to keep up and I will loose battery % as I drive.
All in all I am very happy with this move from the Captivate. Many see it as a lateral move, but if you ever where in the need for the GPS this is definatey an upgrade since the GPS on the Inspire is spot on.

^^^^^^
thats the kind of info i was looking for. appreciate it.
my first run with the inspire resulted in 14 hours since last charge (down to 15%) with nearly 3 hours of screen on time.
granted i adjusted every possible thing to be less battery consuming, and one hour of that screen time was laying in bed in the dark with the screen on the lowest brightness setting.
i think i may be able to work with this.

yeah i am close to an impulse buy on the inspire too, just because its such a great price. even full price at 399 is insanely cheap when most phones are 550 full price.

the battery does suck. but everything else on the phone is so great, that i still am happy i got it

I am a pretty hardcore user and I never have any issues with battery at all. I believe a lot of these battery issues that people have are due to flashing with a low battery, which causes the battery's "memory" to get messed up. If people flashed with a full battery, or did the battery reset procedure after flashing and charging, we would stop hearing about all the horrible battery issues. User error, not an issue with the phone. If it was a phone issue, I would absolutely be experiencing the problem as well.
There are also bigger, better, higher capacity batteries up to 3500 ma/h if you REALLY need more battery time.

alright so i had a lot of issues with getting great battery life out of the phone. i'm only writing this to help people that are having similar issues. obvious, relative to teh atrix (with a ridiculously larger battery), the life is NOT that great. BUT i've gotten 24+ hours on teh phone with certain tweaks.
first off, rooting is a pain in the ass, but a necessity for any power user. My HSUPA speeds are often higher then the HSDPA speeds...and I can tether too! Anyways most important part of tihs is underclocking. I have my screen set to underclock to 3xx Mhz with screen off. I can't even tell the difference between when it is underclocked or not. I don't OC since for whatever reason I don't see the option to and don't care to force it.
I also set my brightness to 20% or less when i'm indoors, which is usually where i am. I also turn off the radios when i'm not using them, or wifi when i'm in range (i think its better than hspa), and sometimes autosync too (there are widgets for this). i also disabled facebook live feed syncing and set it to update when i open the app, and to sync contacts and htc sync and other useless stuff to once a day.
if you want something to turn off your radios when your screen is off, check otu juice defender. if you want to track your battery over time, try juice plotter. with the way i ahve it setup now, if i leave the screen off for 10 minutes. the battery drops 1% or less PER HOUR. One night, it finished charging at midnight so i took it off, and didn't put it back on a charger 1 am the next night with 10-15% left.
anyways, i hope this helps at least some new inspire owners. good luck with rooting if you haven't yet, it took me 4 hours, but itw as COMPLETELY worth it

Got another data point for the stock rom.
This time after the 8h my battery was at 55%, however I spend considerable time in a clean room were I have no signal at all. My other phones would usually drain much quicker in there and I believe it's because it's seeking a cell signal all the time.
So far I am very happy with the rooted stock rom, only wished it had some of the Gingerbread features.

I have consistently gotten about 9 hours usage, with 1.5 - 2 hours screen time, and left work with 40 - 60% battery. I make no effort to reduce usage, as nothing even comes close to the screens usage, except I do leave off gps when not in use. This is a general average, and I have noticed little difference between stock and 2 different versions of Android revolution, with different flashed radios. (roms always flashed at full battery) and overclocked to 1.2 with ondemand set. Overall I can say this battery is not great, but the rest of the phone is well worth it. I had the atrix for 2 weeks, and although the atrix got better benchmark scores, it was way less smooth, and a lot of market apps don't work on it, like flashlights, live wallpapers that don't support the screen, etc.
I am very glad my atrix's touchscreen failed, because if it didn't, I probably would have never tried the inspire, and I am much happier with the inspire.

Is it just me or is the Thunderbolt battery life... kinda good?

So, I was well informed from many different sources that the biggest drawback to the Thunderbolt was the horrendous battery life (people complaining in the 4 hour range). I came from a Samsung Fascinate, which would most of the time get me through the day, but just barely, and the Battery Use was almost always 70-80% screen (even at the lowest brightness). I primarily got the Thunderbolt for the possibility of 4G tethering, so the first thing I did was buy an external battery charger pack (extended battery was sold out).
Well, I've had it for a few days now and despite geeking out on the phone, tethering whenever I can, using it probably more than my Fascinate, I haven't had any issues with battery. I pulled it off charge about 8am this morning, it's currently 9:45pm, I've been using it pretty heavily all day, tethering on the train to work, using it at work, and using it the whole train ride home, and it's currently at 33% battery. 6:18:00 Awake time. Where is this horrendous battery life I heard about?
I'm not using any battery saving utilities (Juice defender etc), have it set to Auto Brightness, just letting it be on WiFi when WiFi is available. I'm using the bone stock HTC Android 2.2 that came with it, not root etc.
So far this phone has much better battery life than my Fascinate and I'm pretty impressed, especially since I believe it has a slightly smaller battery. If I check battery use today, it's 59% Display, with the next highest being 9% Cell Standby.
I haven't used it as a 4G hotspot for more than maybe 30 minutes at a time, but even then it doesn't seem to die too quickly. Am I just missing something that other people are doing that drains their batteries like crazy or is it just that I'm careful about not using stuff the indiscriminately uses 4G for no reason? (I removed all the auto updating widgets like the Friend Feed etc).
Anyone else had a similar experience?

Ummm, yah, well, it's just you...
JK... the battery is ok for me I haven't had it die on me yet but when ever I drive it goes in the charger so I'm sure that adds up.

It's you.
Seriously though. Go to any one of the Thunderbolt forums or read any Thunderbolt review and you'll see the battery being discussed prominently. There is definitely an issue with it. Who knows what it is though..
The thing that really bothers me is the battery isnt consistently bad. Like the last two days Ive gotten 24 hours of use out of my phone. Normally that's unheard of.. but next week something will happen and it will be back to being dead within 6-8 hours with barely any use.

You are correct that this issue is oft-cited in regards to the TB. However, I think the 4 hour data points may be slightly exaggerated. I wound up buying the oem extended battery because I wasn't make it past 6.5 hours with regular use. I travel pretty far to get to work every day, switching between many towers over the course of my commute, constantly going from 4g to 3g to 1x and back. Besides the screen (which will be the biggest battery drain on any phone with a modern touchscreen) data should be your next highest drain, and the biggest variable you are capable of tweaking to change your battery performance. My 6.5 hour experience was with a pretty abusive data usage scenario, and I don't see many people inflicting much more upon the battery in actual, real-world use. That said, with the extended battery, the TB has the best battery life of any phone I have owned in the last five years, and I couldn't be happier.

I'm getting about 12 hours with pretty heavy use. Running BAMF 1.6.2 with kernel overclocked. I'm pretty happy with battery life...it's just as good as it was on my droid incredible.

I have learned thru experience that all HTC phones with 4.3 inches screens are bad at battery life. When I say bad, that's comparing it to a smaller less powerful device. But take in account all it does and to me battery is ok. I mean the HD2, and EVO when I owned them were battery hogs. But I always had a charge. Ppl want bigger and faster phones,Well there's a trade off until battery technology catches up, the bigger phones will consume more battery. Its like saying I want a better car more sporty and trendy but I don't want to pay that much. Not goin to happen.

With just 3G available to me and using everything stock...I get slightly better battery life than I did with my incredible that was on CM7. Compared to a stock incredible, much better. I'm a bit scared for when I do get 4G seeing all the posts though =)

Rooting gave me an extra 2% per hour usage. I can go 15 hours and still have 40% left on my battery. I'm happy with this battery.

Thunderbolt has better battery life than my Samsung Epic had. Stock, my battery wasnt all that great. However, changing some settings and finding a suitable kernel has helped with my battery life.

I have had the same experience. Coming from a Fascinate, the Thunderbolt is so much better on battery life. Mind you, I do not live in an LTE area. This is what I do:
- Juice Defender (Balanced settings)
- Brightness - half way
- GPS only on when I need it
- Wifi on almost 100% of the time (at home and work I use only wifi)
- Non-Rooted
I even have 100+ apps installed including leaving Google Talk and Yahoo Messenger on almost 24/7. I have about 8 or 9 widgets as well. Most that pull info.

The terrible battery life comes when the phone tries to hold a bad 4g signal drains the battery at an insane amount. If you're in strong signal expect much better battery life but because 4g is so new I expect a lot of people to be in areas with low 4g signal as Verizon has not even turned up 85-90% of the towers past 45% power.

I've had the TB for 3 days now and am coming from a rooted Eris (running xtr rom). I have noticed that with the same amount of usage I am also getting better battery life on the stock TB than I did on my Eris. I am in an area that does not have 4G so I have that turned off.

I'd love to see some sources backing this info up.
When I bought my TB I left the store with the extended battery in. The battery easily lasts me all day. After reading all the complaints about how bad the stock battery is I decided to try using it and I'm actually surprised by how long it lasts. I was expecting much worse. It's easily lasted me 8-12 hours with my normal everyday use. I'm going to stick to the stock battery from now on. I was getting annoyed by the heft and bulkiness of the extended battery. My phone feels so sleek with the stock one.

Yeah, I'm with the "it's just you" crowd.
Pretty bad battery life for me here in NYC (plenty of good 4G around).
Not a heavy data user (less than 20min browsing per day).
Not a lot of long calls.
Accounts update once every hour (FB, 2 email accounts).
Brightness at min.
No video playing, no music playing.
No speakerphone used.
Rooted, BAMF 1.3.2
GPS and WiFi rarely on at all.
I'm lucky, --LUCKY--, if I get like 6 hours out of a fully charged battery.

Just curious, why are you still using BAMF 1.3.2?

running Bamf 1.6.1 and Imoseyon Lean Kernal set at 1.4Ghz with SetCPU on Smartass, along with ATK set to kill every 30 mins(oh I know they are the devil, yet my battery life is always better with one, so no comments about how they are bad.) I also always have 4G on, and usually fluctuate between -82 to -94dB in signal strength, and wifi is never on, as my home network is strained enough as it is. GPS is always off unless I need it.
I also use WPClock Live Wallpaper at the same time.
Yesterday I was at 18% with 2 days since last plugged in.
Of course I also calibrated my battery, after flashing Bamf 1.6.1.
I use my phone alot for facebook, angry birds, browsing the web and a crap ton of texting, I probably hit near 1000 text a month, I know that isn't what the high school brats are pulling, but still, for me, that is insane.
On my Evo 4G, with 4G off, I could hit 3 days running CM7 underclocked to 750Mhz max. That was with a bigger battery as well.
I am very exited for CM7 to go into a beta, or nightly stage, and the kinks worked out, as I am sure with 4G on I can hit near 3 days with the Thunderbolt as well.

Update your sig, brah. Still says your running Tesla Coil.

Overall battery life is a lot better than my cm7 Incredible, and on mostly standby it lasted quite awhile before I had to charge it (I couldn't use it for a few days because vzw wonked up on activating my TB somehow), so it lasted almost 3 days with only occasional data use/seeing if the phone was working (I couldn't send texts or make/receive calls, but my data was working)

I know, I am a lazy ass, haha.

Is the battery that awful???

I have a Droid Inc 2, but I wanted to switch to the Tbolt, but have heard the battery is awful. As of right now I am in a 3G only area, but will have 4G soon. I see the Tbolt has a 1400mah battery while the Droid Inc 2 has a 1450Mah battery, so would the difference on 3G be that much??

My battery life is good...usually get 2 or 3 days on a full charge ..push exchange mail. Gmail. Friendstream.phone calls texts etc?

On 3g the battery is not that bad. I don't have 4g where Im at and when I was on a froyo rom the battery would last all day no problems.
When I go into SanFran I get 4g and it seems to way more battery if Im using the phone but it doesn't seem too bad. I just have to keep a charger handy butt that doesn't bother me.
Benefits of the thunderbolt are a bigger screen (part of the battery "problem"), 4g radio, and the development is here unlike with the dInc2.
Stock for stock I think the thunderbolt still wins for me. I was thinking about getting my wife a dInc2 but the lack of a development community kills it for me. Maybe it will pick up at some point but IMO its a step backwards for Verizon to release new phones without 4g.
If youre not going to root and stuff then it's not such an easy choice. If you are then IMO the choice is clear, get a thunderbolt.
Hope this helps.

my thoughts
Yes, on 3G or WIFI the battery life is solid. I get a full day easily with gmail constantly syncing, gtalk on constantly and widgets such as beautiful widgets, calendar, twitter and face-book on constantly. Also, I work in a hospital and access patient data frequently on my phone. This is via the internet and data is refreshed at each access (50+ times per day). BTWI take the phone off the charger at 0530 and don't get home till 1930, and still have some juice left for the ride home. And I don't use any battery savers, or task killers.
But when I turn the 4G radio on, and there is frequent hand-off from 4G to 3G, the battery is dead in 6 hrs with the use stated above.
That said, when I go into the city where 4G is very strong and consistent, I can get a full day (8-10 hrs on 4G).
What I suspect happened when people first got the phone, is that they were so enamored with it; speed, screen, etc...(myself included), that the battery took huge hits, and everyone cried at how terrible the battery life was.
As with everything, wait for the dust to settle and you find the truth is somewhere in the middle.
Nevertheless, I still would like an 1800mah battery that fits the standard door.

Until 4G is fully developed in your area this phone isn't worth it. I've been through two of them that are frequently heating up when they're doing nothing but sitting in my pocket with auto sync off, brightness as low as possible, no notification LED, etc. It's pathetic. It over heats and drains into yellow by noon. 4G is amazingly fast, but since the outages it hasn't been the same. It comes and goes in areas where it used to be four bars.

If you're not in a 4G area then you should be good. Those of us with 4G are having a tougher time with battery. If I leave 4G running then my battery will die in less than 6 hours if with light use.
I most often turn off my mobile network though, letting me get around 8-10 hours.

On 3G, with the normal battery, it was much better than my old Fascinate.
With LTE, I went to the extended battery, and I struggle to get through the day on moderate-heavy use. (On LTE with the Regular battery your toast).
BTW, I am unrooted and am using Juice Defender.

There are apps on the Market which allow you to switch between 3G and 4G. I leave my Thunderbolt on 3G unless I am checking the internet, Facebook or Twitter. I usually get a full day on the stock battery. That is better than my battery usage on the LG Ally.

Well with the bamf gb remix i get 6 hrs full power all the time,everything possible running, slacker,maps,fb mail all syncin 10min,thats about 2 hrs better than my imagio, about 12hrs with just moderate use,i think thats pretty good.

I live in a 3g area but I'm only a few miles away from 4g. As long as I'm in a 3g area my battery is good. But as soon as I enter a 4g area its not so good. It doesn't bother me too much since I have a car charger and have about ten usb cables and micro usb chargers laying around. But I probably will invest in an extended battery once VZW deploy 4g in my area a bit more.

Some good tips to get more out of the battery are...
1. For a good 10 - 15 days be sure to drain the battery all the way and then fully charge it.
2. When the phone is fully charged remove it from the charger. You may notice that if you leave it on the charger for a while after its fully charged it will go from 100% to 97% usually within minutes.
3. Screen protectors decrease the battery life due to holding heat into the phone.

You sure about that last one? I don't think screen protectors cause excess heat. Good tips otherwise.

I came from the Droid 1 and I think that the battery life is about the same. I have no complaints about it. I do live in a 3G area though.

Why do you suggest to fully charge and drain the battery for 10 - 15 days? I deained the battery fully a couple of times when I just got the phone. Do you think I should repeat the procedure?

fully draining the battery shortens its life span. and once it reaches 100% charge, it stops charging and begins to drain--taking it off/leaving it on are the same.

These batteries don't need to be "conditioned" by fully cycling them. All that'll do is help calibrate your gauge.

I trialed the DInc2 for 2 weeks and switched to the Thunderbolt while my wife stuck with her DInc2, after rooting and installing Das Bamf 1.6.3 remix with adrynalyne's kernel, I easily make it through the day with moderate usage (autosync on, several hours of gaming, hundreds of txt, hour of phone calls) on 3g/wifi. DInc2 will get a couple extra hours in a day with the same usage, but you get a phone with 4g capability for the future, a larger screen, and all the support of the devs here for your rooted device while my wife's waiting for her DInc2 to still be rooted.

Best thing to do is just buy some cheap ebay batteries. I use those and I keep a few in my pocket just in case

Sounds like you have got a rogue app you need to take care of, more so than the phone being bad.

Battery Life, Oh?

I think it's crazy how many people are downing the battery life on the Sensation. I used my phone a bit today. Off the charger at 10AM, used GPS to go to work with Bluetooth activated as well. Forgot to turn them both off while at work. I used my phone like ever 5 minutes checking Twitter updates(also weather/news/facebook/email/etc updates are automatically updating as fast as the app allows. So quick updates for all my apps, GPS and bluetooth turned on all day. Home around 5, watched a few episodes of South Park on Netflix with my phone. Read some news. Played a few different games for about 5-10min each just trying out new games. It's now almost 1AM the next day, and I'm above 40% battery life. I manage my screen brightness, that may be the only thing I remembered to manage well today. While outside/in car, full brightness, inside, as low as possible.
It's shocking to me when I see threads of how the battery life stinks. I'm using the stock battery, I don't even seen the need of getting a larger battery because this already gets me through a day full of activity. Anyone else find the battery life on this device, quite handy? Mine is rooted, but it's stock ROM. I'm also using a skin posted by a member of our forum, the transparency. I'm running the stock T-MOUS(why is it called tmous..? are people that lazy to spell out t-mobile?) ROM, because I accidentally deleted a few apps I discovered I needed back, and did not do a backup. Oh, and I'm also using the battery mod, for the battery icon in my notification bar.
I guess I'm just praising the battery life, is all

I have only had my sensation for about 5 days and battery life is amazing! Im still stock too.. I came from an evo 4g rooted running cm7 and or miui and battery life doesn't come close to being as good as my sensation. Not only is battery life awesome, this phone is awesome. I moved to Southern California a couple weeks ago and Sprint out here is horrible.. so I switched and couldn't be happier. Plus I like this phone was better than the evo series. Battery life is sweet!

You would have to post a screendoor shot of your battery usage and screen on time to completely determine how much the phone was used and how long the screen was on.
Bluetooth and GPS don't use any battery or have low usage (depends on the chipset because some completely turn off) during standby since they're not being used at all.
So we can all praise our phones for having good battery life, but it all depends on usage. If you don't use your phone a lot (you could turn on your screen every 5 minutes but at the end of the day have only like 45 minutes of screen on time and like 70% battery left.) Then you get good battery life. Use your phone a lot and quite simply battery life sucks.

I think it can largely depend on how you use your phone, not just how often or for how long. For example my Fiance also has the Sensation and on her first charge she got 3hrs52minutes before hitting 10% battery. Since then she has only gotten ~2hrs each day now that she has Twitter and Facebook for Sense accounts set up.

That's not good. There's gotta be something wrong with either her phone or something. 2 hours of battery life warrants an exchange.

The phone lasts longer than 2hrs, that's 2hrs of the screen being on. my sensation get's about the same. This is with Gmail on Autosync and Twitter/Facebook for Sense accounts enabled too.

If I do what u did, my batt will be flat in 6 hours. Somethings just not right with my sensation.

Oh! Makes sense..
But 2 hours with screen and dead in 6 hours? I'm glad I have a G2x then. Cause I get 3 hours and like between 13 and 16 hours.

You can go by statistics and on screen time and what not. but I just got home from work, and I literally used my phone for about 2 hours straight calling carriers for a customer. I'm above 80%. So from 9AM-4PM, only saw a 20% drain. Once again, keeping BT and GPS on just to see how it goes. ALL of my autosyncs are once again, on, and set to the most frequent can be.
Compared to any other stock phone, this is amazing. Compared to my Cyan N1 and my Cyan NS, it's not a huge difference. Although, at this rate I may give the lead to the Sensation, since I'm leaving all these extra features on throughout the entire day.

good
I get two to three days out of my Sensation, and I'm a relatively heavy Internet user... don't phone much.
At first I wasn't getting great mileage - having to re-charge after only 10 hours or so, but did two things to improve it dramatically...
First, charge the battery once using the following method:
1. charge battery to 100% and leave on charger for an extra hour
2. unplug the cable, turn off* the phone, and plug the charger back in. leave charging for another hour.
3. unplug the phone, turn it on for two minutes, turn the phone back off*, and plug in the phone again. leave charging for another hour.
* when I say "turn off", I mean completely, without fastboot. so either disable fastboot before switching off, or turn off the phone and pull the battery then put it back in.
Second:
Turn off automatic screen brightness, and set the brightness manually to what you need. Ideally, I'd like to have an auto-screen brightness adjustment that automatically sets it, say, 25% lower than what the built-in function does.

That's pretty exceptional. I usually get 13-14 hours with 5+ hours of screen time before I'm at 20%. Using the chichitec battery, btw.

My chichitec battery went 18 hours yesterday before it got to 10% and I charged it. That was with a lot of web browsing, some phone calls, music, games. Id say, medium-heavy usage.
Matt

Same here I have had several Android phones with different carriers and this is hands down the best, on par with the iPhone I had previously with Verizon. No problem getting through the day with Exchange and 2 IMAP accounts and heavy phone use, the only mod is I set screen brightness, battery is stock.

no one is complaining i watch sparticus on netflix and game of throne on hbo go for 5 hrs straight while facebooking random hoes . and i am out of battery..
we are complaining that the 4g drains the phone while on idle.

this is the best battery life i've ever had on a phone. i can't complain at all... i even have gps on and i could never do that before. lol!

Guys, having GPS on doesn't use any battery. It only uses battery when it is active. So for most of you 99% of the time your GPS is off aka standby or whatever you wanna call it.

One reason many people complain about bad battery life is that it seems some Sensation models are actually faulty. Best evidence: TechRadar review.
http://www.techradar.com/reviews/phones/mobile-phones/htc-sensation-943466/review?artc_pg=9
UPDATE: We've finally managed to get our hands on a new review model of the HTC Sensation, and the good news is the battery life is definitely improved.
It seems that a combination of data-hungry applications and a slightly dodgy model caused the odd readings from before, although we're not entirely convinced the above scenario isn't one power users will face, which is why we've left it in.
But in normal use, and by that we mean sending 42 texts, spending 49 mins on the phone, watching an hour and bit of video and using the music player constantly, plus a few minutes spent using GPS to track ourselves and browsing the internet for roughly 45 mins, the battery pretty much lasted the day, although it was often in the yellow zone come 11PM.
However, what was more impressive (and a relief) was the sleep state of the HTC Sensation. Where before the phone would get very hot and start spewing out battery life in our pocket for no reason, if you leave the phone locked up for around 10-15 minutes on our new model the power consumption dropped to almost nothing.
