For the first few days the battery life in my brand new Sensation sucked too. I was getting maybe 8-9 hours of moderate usage before having to plug it in to recharge.

On Friday night (June 24th), I did a full factory reset through the bootloader, installed Juice Defender and set it on Aggressive setting, and charged it overnight for about 8 hours while the phone was turned off. Yesterday (Saturday, June 25th) after over 18 hours of moderate use, which included many phone calls, emails, some texting, browsing, playing with the phone, and even a little bit of Stupid Zombies, the battery was still at 42%!!!

I charged it overnight again for 8 hours. So far today, after 3.5 hours of HEAVY usage, the battery is at 93%. I am beginning to like this a lot!
[HTC Sensation] The_Biz:
Email auto-sync, BT on at all times, some internet radio streaming today and still at 91%. It's been off the charge for 3 hours now. I think that's pretty good compared to my HD2.
[HTC Sensation] knobgoo:
I have been very happy with the battery life so far, its better than the battery life was on the MyTouch 4G I had. Can go a whole day no problem, MyTouch 4G couldn't make it a day....
[HTC Sensation] smacman:
To all you guys that are getting phenomenal battery life, could you check your battery stats and tell us your display usage?

Thx
[HTC Sensation] jlevy73:
I will post battery stats later today but battery life has not been as good as I hoped. Compared to the G2x I'm getting worse battery life. Then again, it's too to compare a device that is running a custom rom versus stock.
[HTC Sensation] PG101:
I did already.. with much detail :) Below: (Now 17H 15M down to 48% - so, lost about 4 percent in 2 hours, with some more use)
[HTC Sensation] smacman:
I still don't see your display on time there. Maybe I'm blind.. :)
[HTC Sensation] PG101:
Not blind :P... are you looking for awake time?

3 hours 11 mins
[HTC Sensation] smacman:
So with 48% battery left your display had been on for over 3 hours? That is excellent.. Definitely something wrong with my battery if that is the case.
[HTC Sensation] PG101:
Yup. thats what i read... maybe i should tell you what I did when I got the HTC Ssensation...

I used it and set it up on that batt level that came out of the box... till it switched off... kept if off and charged it the whole night.. about 7 hours.. unplugged.. turned the phone back on.. used it again the whole day and brought the battery level to about 19%.. turned it off.. charged it again full for about 7 hours... and now i am using it as normal!!

EDIT::: hahahahahhahahahahahaha.. no wonder... I am sorry.. its a typo.. 2 hour and 11 Mins.. well now 18 mins!!!

Still quite decent I think.. with the usage!!!
[HTC Sensation] r3awak3n:
My battery sucked too but its doing much better (ibwas not worried because the same happened to my nexus one). Always moderatevuse and I get about 16 hours of use and still have about 40% left.

I have auto sync on, wifi off, screen brightness on about 60%.
[HTC Sensation] jrwingate6:
This is probably the longest lasting device I've used in a while. My G2X would get me about 11 hours with moderate use but my Sensation will last close to 16 hours with moderate use.

The only thing I have syncing is my Gmail account and calendar. I turned off everything else including weather. I also never keep my display set to automatic since that's just another piece of hardware that constantly has to work. Unless I'm in direct sunlight, my display stays at 50%.
[HTC Sensation] :
Its definitely HTC sync killing the battery. I turned it off and now im lasting into the next day.

[HTC Sensation] Spybreak:
I can't seem to break 2 hours display time on my Sensation. I've disabled all HTC stuff, using Launcher Pro and pretty much no widgets.

By the time the day ends, after 13-14 hours the display has been on for 2 hours and battery is down to 5-10%. How the hell are people at 50% with the display on for 2 hours?
[HTC Sensation] PG101:
Read my complete post with settings and actual usage.. maybe it helps!
[HTC Sensation] :
Friendstream
[HTC Sensation] :
Thank u my friend. LOL
[HTC Sensation] Spybreak:
What I mean is that with my display at 2 hours on my battery is at 10% max. I am not using HTC's launcher so it can't be Friendstream.
[HTC Sensation] jrwingate6:
Right now, my phone has been off the charger for 9 hours. I have 2 hours and 12 minutes on my display which has been on max brightness all day long since I was at the Orioles game with the sun shining. The phone was also on 4G all day and I still have 35% battery left. If I would have been indoors with the display set to 30%, my phone would still have 50% battery left.

All in all, I think this battery rocks.
[HTC Sensation] novacatz:
I gotta believe there is some teething problems with the firmware - i have had the situation where plugged in, at full charge and then somehow the phone CPU goes into a tight loop.

End result is even though plugged in - the charge is going down very quick, maybe 100% down to 75% in 15 mins or so. phone is very hot too.

Excepting the several occasions of the above - i have found the battery not great. Probably get down to about 70% based on 2.5 hrs of usage based on:

Winamp in background

some light screen usage (maybe total 20-30 mins max) - brightness on auto

widgets in the background (I do use a lot, friendstream, email, calender, to do list)

Would be nice if I could trust the phone for 8 hrs of that usage pattern to still be around 30-50% - i dont mind charging everyday but if I have to modify my behavior coz of the battery i think that isn't so good.

I gotta believe that this is a firmware issue (or the battery is a china fake and it isn't really 13xx mAh)

[HTC Sensation] yourpassenger:
I'm getting about 8 hours, bearing in mind have a lot of things syncing every 1-5 hours (facebook, news, weather, email, twitter, podcasts ) and I have plenty of widgets on my homescreens. I'm using the phone a lot (can't help but play with it) Mainly browsing, IM, games, playing music. I have screen set to auto during the day, sometimes max in bright weather & 45% if I'm in bed at night.

I got this phone so I could use it and maximise its features and power. Don't want to restrict everything just to preserve a few more hours of battery. So far I'm very happy!

Sent from my nokia 3210
[HTC Sensation] zim2dive:
The folks who use the word "restrict" don't get it.. I simply enable what I need when I need it. My schedule is regular enough that I can automate 95% of that and then forget about it.

And for that very little extra effort, I get much more battery life vs. the folks who are so proud of running un-restricted.
[HTC Sensation] steve austin:
I am on my fourth day of using the sensation. I am trying to give it seven days to see if the conditioning process makes a difference. However, so far I am not happy. Full disclosure, I am coming from an HD2 and was hoping that with native Android on a flagship phone I could do away wit the current widget and constantly monitoring my battery. With that said...

The good: The sensation is a BEAST when it is in sleep mode. * hours on standby and I went from 100% to 95% - spectacular. On my hd2 It would be down to 70-75% in the same time. Awesome.

The bad: Ok, today my starting point was from the 95% I sent 2 text messages and had ONE 40 minute phone call. My battery dropped to 71%. The screen was off, no bluetooth, no nothing. Almost a 25% hit off of one phone call?

Yesterday I took 6 pics, Tweeted them, checked FB 3 times, responded to 5 fb comments and sent 5 picture messages. To add to that there were no phone calls and no internet surfing. My battery went from 100% to 8% in 4 and a 1/2 hours. The only thing I had going on in the background was fb and twitter checking every 4 hours.

There must be a real disparity in what we all consider "heavy," "moderate," and Light usage. I would say that yesterday was very light to moderate and I did not make it for 5 hours. That is not acceptable. I could get close to that type of performance with my HD2 (on occasion). How is everybody logging at least 8 hours around here? I have read the tips and this is not working. Any OTHER suggestions or ideas from what has already? thanks in advance.
[HTC Sensation] Basil3:
Depends what you use. I used to be a heavy Google talk user, but when using the likes of juice defender, I would have to wait for the network to log back in. After that, sometimes I would get a missed message, sometimes I would get an email saying that i had missed a message when I was offline. I just found it annoying and the gain in battery life didn't justify it for me.
[HTC Sensation] xnifex:
it's been my experience that phone calls drain the batter on this phone really fast

I am new to the android and its battery consumption. (previous blackberry owner) For those of you that been on android for quite some time, how did my battery usage fare compared to yours? I just want to know if my consumption is in the norm.
[HTC Sensation] steve austin:
man, I find myself just watching the numbers blow by and not wanting to talk. The battery longevity of HTC phones really is beginning to irritate me because I thought that having something native and having a bigger battery would help. Its already bad enough that the screen sucks the life out of the phone and you have to dim it to preserve some type of life and now you can't really talk either?
[HTC Sensation] boardwak:
What are people getting for standby battery usage? I'm coming from an HD2 running android where I got consistent 3-7 mA drainage with the screen off, but wifi/google sync/mobile data ON. With the Sensation my lowest measured drainage is around 12 mA, but it's usually in the 20s or 30s. Again, with the screen off, but wifi/google sync/mobile data on.
[HTC Sensation] infamousjax:
You can't "train" Lithium Ion batteries.
[HTC Sensation] Sdobron:
I've gotten almost 40 hours...35 minutes phone calls, 3.5 hours display time. Honestly don't know what is wrong with everyone in this thread because they are doing something wrong. Probably not turning off data when it's not being used.
[HTC Sensation] ags29:
I would say the battery is amazing when wifi is on. I get about 4 hours "display on time" if I'm on wifi. However, when not on wifi the battery just sucks -- leading me to believe that the 4G radio alone drains the phone insanely fast.

I turn on airplane mode whenever I won't be using the phone for a while and it saves me a ton of battery.
[HTC Sensation] DoogieDC:
Good point, infamousjax. The phone charger is designed to take the battery up to just over 90% capacity and then shut off.

The post linked above gives instructions on how to overcharge the phone. True, if you you charge your phone, turn it on for a couple of minutes, then shut it off and charge again (repeat x number of times) - you can fool the charger into taking it up to 100 capacity. Yes, it will power your phone for longer if you do this. BUT the battery will degrade about 75% faster. In a year it will be just about worthless.

Lithium batteries function best when undercharged and never completely drained - in other words they like to live in the middle between 70% and 30% charged. If you just let the charger do it's job and then avoid pushing the battery down to 0% charge, your battery should last for 4 or 5 years and still preserve at least 75% of it's capacity over that time.

Advice - before you use the phone for the first time let it charge up until you see the green light. Then proceed as normal - there is no battery vodoo ritual you have to perform.

Details on how lithium batteries work and how to take care of them are in the article How to Prolong Lithium-based Batteries.

Juice defender ftw

15 hours in 50% left.

Well u have dual core so ur gonna get better battery than most phones but my single core vibrant still up there ^.^
[HTC Sensation] jonathan3579:
I have had this phone hit 19 hrs before but for some odd reason, today only lasted 4 hours with absolute minimal usage and running EDGE. I hope it was a fluke.
[HTC Sensation] aNYthing24:
My battery life has been really bad thus far. I took it off the charger 6 hours and 54 minutes ago and there's only about ~35% left with very light use. I don't know what the problem is...
[HTC Sensation] r3awak3n:
Update. Its been 17 hrs since unpluggled and still have 38% bat left. Moderate use, screen on 60% brightness, 2 gmails syncing and light web browsing. Not bad at all.
[HTC Sensation] zim2dive:
Just went on the charger.. so add 24 hours to my previous totals. So I'm very happy with battery life.

I may not use the phone as heavily as some (ok, most :) ) but I am able to get 3+ days on a single charge without sacrificing anything... ie. I make use of any/all features needed when I need them. Perhaps I just need as often.

My Sensation

Hi....

Dunno what i would be called (light /moderate or Heavy user).. Just posting my days activities. Have been calibrating my battery for the past three nights as mentioned else where...

Unplugged for approx 10 hours left with 35%

Display - 53% - 2 hr 31 min

Voice - 38% - 38 min

Cell standby - 5%

Wifi used for 5 min during day

Angry Birds - 10 min

Texting - 10 texts sent...25 received

Email - Regularly checking on GPRS... Say every half an hour.

Installed two applications from the market.

Screen set to auto-brightness.

Dont use any battery saving programs.

No heavy widgets except the stock HTC widgets

Have been using Sync all day (but only on GPRS not 3G)...

Sync facebook contacts, feeds and Google sync

Turned off Live wallpaper

No Music / videos

Turned off full screen weather animation

AND YES did a complete shutdown (not fast boot) and restarted during day.

Past three days avg is that all the above make my battery last for approx 15 -16 hrs.

BUT as someone said (and correctly too) lets enjoy the phone with keeping it on USB. We bought it to use it to its maximum otherwise any Nokia phone would have been just fine for us. ;);)

[HTC Sensation] smacman:
Based on the majority of responses in this thread, I think it is fair to say that the average amount of screen on time that the Sensation's battery can handle on a single charge is 2-3hrs. Some have managed to slightly exceed this by actively managing their brightness, but not by much.

I think with this calibre of screen, this is somewhat expected. Still a shock for some of us though depending on what our previous phone was. I will keep a fully charged spare battery in my wallet. This thing is too awesome to use sparingly.
[HTC Sensation] crisisinthecity:
I removed the friendstream widget from my home screen, (which I read eats up display battery usage), and its made a HUGE difference. I have had my phone off the charger for 4 ours. Moderate usage and I'm at 96%. Before I'd be around 80 already.

Auto brightness on.
[HTC Sensation] r3awak3n:
25 hrs and still 24% battery left and I know the phone staysbat 4% battery for about 4 hours for some reason
[HTC Sensation] Trekest:
Well, I beg to differ. Today was my first day with the Sensation, and as a result, well, it might be an understatement that I used it quite heavily.

I've gotten ~7 hours on a single charge, ~90% of which the screen was on. This included taking videos, heavy gaming, browsing market, transferring files over Bluetooth, and all of these without changing the brightness from its stock auto setting. Quite(ly) impressed.

Edit: added attachment of the battery graph.
[HTC Sensation] NoModE:
I'm running RUU Europe 1.35.401.1

Much better now :)

Charging is also much faster.
[HTC Sensation] smacman:
So you are saying you got 6+ hours of screen on time out of your battery? Very impressive. I stand corrected...
[HTC Sensation] smacman:
Not that I don't believe you, but can you send a screen shot of your display on time value? It would be great evidence for those of us that have faulty batteries.
[HTC Sensation] Trekest:
Sure, though I'm not sure how helpful that'd be since I've started charging my phone already and played a bit more with it.

Either way, here are the updated stats. My guess is that the original screen on time (i.e. before I plugged the charger) was roughly 5 and a half hours, not 6.
[HTC Sensation] Profondo_Rosso:
I got 7 hours screen on time my first day too, and that took it down to 10%. but 2 hours screen time and everything else going on usually nets me about 14 hours in daily use

Sent from my HTC Sensation 4g with extreme prejudice
[HTC Sensation] steve austin:
things are improving a bit...

unless i am misreading, there are a lot of people with great battery life, but there does not appear to be any serious use of the phone. checking fb twice, a few texts, in standby for several hours and two calls will not put any real stress on it IMO and from my experience. So I really don't know if I can use a lot of examples that I am readings as a true gauge.

now the guy who i am quoting (above) sounds more like me. I waited to get this phone to use it in its entirety. I got frustrated the other day with my first post in this thread because I got hammered on battery life this weekend and I did NOT do anything and I barely got five hours. So I made a few adjustments (detailed below) and i can say that I am on 9 hours/ 20 mins on one charge. I have 18% battery left. My stats:

display 80% (3 hours / 12 minutes time on)

cell standby 9%

calls 4%

phone idle 3%

maps 2%

I text, sent picture mail, used maps (with gps on), had pulse, fb, twitter, gmail and friendcaster sync'd in the background, took several pics and uploaded them, used tap-a-talk to read xda posts, and facebooked. From 5 hours to 9 - I'll take it. I am still not where i want to be, but this is the first day that i felt good about having this phone as my primary device. I hope to get to upwards of 14 hours like i see here in this thread. to get here today i had to do several things to improve my odds.

1. i did not want the signal jumping around so WCDMA only

2. installed advance task killer and set it to "when screen off" and "crazy."

3. installed ultimate juice defender.

4. Did not want to, but i took screen brightness down to about 80%.

I will continue to drain the battery to almost nothing and let it fully charge. I will report back any positive or negative results.
[HTC Sensation] crisisinthecity:
After removing the friend stream widget I'm getting awesome battery life. Moderate use all day. I'm at 35% battery after 16 hours 27 minutes 46 seconds. Friend stream can be launched from your app drawer so no biggie.

Cell standby 10%

Phone Idle 9%

[HTC Sensation] DeoreDX:
Doing anything besides just e-mail or text just seems to murder my battery. "Normal" light usage for me will have me at around 35-40% after about 17 hours which is just some basic web browsing and e-mail and G-talk. If I use GPS or play games it seems like it drops 1% per minute. Look at the big sharp drop in the graph in the picture, that was me playing a game for about 30 minutes and it dropped my battery 35% in that short time period. This was the game Apparatus. Brightness backlight set to auto. This was around 8pm in a room with just a small overhead light so it isn't like the backlight was set to torch mode.
[HTC Sensation] Jimx2:
You guys should try to get the Anker battery for the sensation.. ever since I got it.. I've been getting 18-22hrs battery life on moderate-heavy use.. well on extreme heavy use just 12hrs.. depends on your settings I guess. My biggest saver I think is the fact that my brightness is on the lowest...

[HTC Sensation] CandyAndy:
Greetings from SGS2 owner. It seems that you guys are struggling with the same problems as your fellow Android users from the Korean camp. Some people have excellent battery life and with some people it just sucks.

With SGS2 we are wondering that certain wifi routers trigger a battery bug which will drain the battery completely. Also there seems to be a bug with Android 2.3.3 which SHOULD be fixed in 2.3.4.

Anyways just came here if I can find some tips for my phone. After all we are all one big familly here :)
[HTC Sensation] Trekest:
Very refreshing to finally see a friend from the "competing camp" not trolling. Hya!

Hopefully all of us will be able to enjoy it sooner than later.

Btw, here's an update - got to 18%, started charging (so I can get back home with some battery). Device was out of charger for 6 and a half hours, 3 out of which the screen was on. Hopefully tomorrow would be a better day.
[HTC Sensation] diosys:
I think it was worse today since it seems you restarted your phone 5 times during the day...
[HTC Sensation] zim2dive:
DOWN to 80%.. LOL.. I'm at 40% (altho now that I check, I'm not seeing a #??.. where did I see that before??). I'm sure that makes a big difference.

The screen is

plenty bright

for me as long as I'm inside (emphasis mine, for everyone who will claim I'm crippling the phone :) )... I'm the guy who can read the "Copyright 2011, printed in XYZ" line on the bottom of the eye chart :)

For kicks I'll switch to "auto" and see what happens.
[HTC Sensation] Trekest:
Really? Didn't know the two were related.

I tried figuring out a weird issue I found with application icons inside folders replaced with the generic icon upon restart. Gave up after a few tries.

The workaround for this by the way is to kill the HTC Sense process (Settings->Applications->Manage->HTC Sense->Fc).
