Battery life is not good on my Hermes, but a couple of things have seemed to make a big difference.
1) low signal areas cause will really drain the battery quickly. I guess it ramps up to output power, pretty obvious really, but quite a striking difference, I used to barely get through a working day, now I've moved jobs to a good signal area, plenty of power left at the end of the day
2) more subjective, but I *think* HTC home was making the device more power-hungry. Anyone else have this experience?
3) long-term the battery is doing very well, it's about 20 months old now and doesn't seem different from when I got the phone.
Long live the Hermes, it was an incremental stage in smartphone evolution, and nothing *massively* better has happened in the past 2 years.

I have been noticing a pretty poor battery life as of late, the battery would be fully charger and watching 30 mins of coreplayer it would put it down to 20%!!
Invested in a new battery (a 1500mAh one off ebay, same physical size) and it seems to be doing the trick now.

It's certainly around the time that all my laptop batteries have tended to start degrading.
1500mAh is 11% more than the stock one, that's nice. Does it fit without modification? Are you allowed to tell me the sellers ID?

Lol sure! The dimensions are exactly the same, naturally you can go for a 2400 or 3000 mAh but they naturally need a modified rear cover.
This is the page i got the battery from: http://cgi.ebay.co.uk/HTC-TyTn-Repl...1229071QQihZ023QQcategoryZ75446QQcmdZViewItem
Delivery was VERY quick, but I am in the UK also so take a look at the delivery times etc... totally worth getting.
i spoke to htc about the abysmal battery life, they say that there could be extended batteries in the near future, with a new back cover (with the back sticking out)
i dont mind charging it every day but
everytime i do something basic, for couple of minutes, it goes down by 1 percent, everything is turned off, gsm 2g mode, etc.
anyway the guy at htc said its due to the massive screen, this is what drains majority of the juice,
For what this device has and what it can do the battery life is pretty good, if you just use it for a few random pics, bit of browsing, bit of music and a few calls you should get a days use, if you sit there for ages messing with it its gonna drain.
Im pleased with it myself, apart from the bugs, but waiting......
It's killing you literally? Step away man!
I find the battery life on-par with other smart phones I've owned. I use a desktop cradle (well should soon be using a desktop cradle) and an active holder in the car, so I find the battery keeps up OK with a typical day's use for me. The biggest battery killer is when the screen is on full brightness so I find essential to have the phone on power when I'm using the satnav.
I had really high hopes for this thread when I read the title. Needless to say, I'm pretty disappointed.
Where's the death I was promised?
Die and prove it.

To be fair most smartphones drain their batteries pretty damned quickly. Disconnect your data connection when you're not using it and bluetooth too. OK so you won't get weather updates but you'll save battery life. Just charge it nightly and buy a car charger if you really drain that sucker!
Wow, I think battery life is good considering the screen, better than I expected.
Currently, with screen set to 70% brightness, push email on 0800-1800 with hourly retrieval outside those hours, hourly weather/Twitter update, automatic Quick-GPS almanac data update, I last all day (~0700 to 2300), and still with about 20-30% headroom with the following use:
Push email as per above settings
50 minutes GPS tracking
50 minutes bluetooth on (heart rate monitor)
1-2 hours listening to music
Around 1-2 hours high-drain use (screen on, using cellular data/WiFi/GPS - for example browsing/app use/gaming/watching video)
30-40 SMS
15 minutes calls
One simple little trick that I learnt some time ago to preserve battery life is ..........turn down the brightness of the screen display. The brighter it is the more juice gets used.
Get the screen to turn itself off after, say, 30 secs of use. That also helps.
The rest, such as killing off data connections when not in use, etc, you already know.
It never ceases to surprise me at the number of negative comments re battery life. The impression I am left with is that if the battery does not last at least 2 months between charges, even though it is being hammered to within an inch of it's life, then that makes the battery performance rubbish. Anyone ever heard of a battery charger?
It's a really easy to use piece of kit that comes with your device that can be plugged in at night when you are asleep, leaving your device fresh for the morning.
Amazing.

What the heck do you expect from such a phone? The energy management is kinda good and it's the display that kills battery life. You have to get use to it. At least my Touch HD seems to last much longer, but I would never change back.
If you watch a video your battery capacity drops quickly. I estimated 4,3-4,5h of HW-acc WVGA video and 3,5h with a non-HW-acc VGA video. Not that much but it really looks fantastic.
My Solution for this problem is: second battery, extended battery and/or load the battery whereever u can. My normal usage drains 30% of the battery a day, so I get 3 days of normal usage (I'm not an excessive handy user). The standby duration is with 300h not that good, but yeah that means still 12,5 days of standby if I calculated correctly.
The point is, that the phone is that good that I'm attracted to play with it and then the battery life tends to last just a day or less.
I bought a second battery (~22€) just for longer rides. I think it's ok.

EEK!, don't come on this forum and complain about the HD2! not allowed. this is now the official HD2 Appreciation society, don't ya know.
I recommend instead you buy some lube oil, massage it into the device, light some candles, play a bit of Barry White, and all will be well.
Then come on this site and reassure all the sensitive souls here that it is indeed the Holy Grail of mobiles and admit you are a Troll for finding a fault with it, and daring to ask about why it does not preform as it says on the tin.
And final advice...In the words of legendary Basil Fawlty... Don't mention the War !..or in this case, the Keyboard!!, I mentioned it once...and thought I got away with it..but no.

Exactly !!
1000 Mhz this bugger does.
And really its more then just a phone. with the battery cunsumption like wise.
But they told me one thing,,. something that Noone does
When you get the HD2. Its battery got 20% juice init.
Thats not for fun of the company (prolly sanyo) was laizy and dint bother to fill em 100%.
You have to charge the battery 6 to 12 hours and to peeking at your new jewel.
And i know Noone ever does that. But it ensures batterylife and eficiency
Here is the article >>
Initialize a new battery. New batteries should be fully charged before their first use to obtain maximum capacity.
Nickel-based batteries should be charged for 16 hours initially and run through 2-4 full charge/full discharge cycles, while lithium ion batteries should be charged for about 5-6 hours.
Ignore the phone telling you that the battery is full--this is normal but is not accurate if the battery is not initialized.
#DO NOT fully discharge a lithium-ion battery!
Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them.
Instead, charge them when the battery meter shows one bar left.
Lithium-ion batteries, like most rechargeable batteries have a set amount of chargers in them.[1]
2Keep the battery cool.
Your battery will last longest if used near room temperature, and nothing wears on a battery like extended exposure to high temperatures. While you can’t control the weather, you can avoid leaving your phone in a hot car or in direct sunlight, and you don’t have to carry your phone in your pocket, where your body heat will raise its temperature.
In addition, check the battery while it’s charging. If it seems excessively hot, your charger may be malfunctioning.
3Charge your battery correctly, in accordance with its type. Most newer cell phones have lithium-ion batteries, while older ones generally have nickel-based batteries. Read the label on the back of the battery or in the technical specifications in the manual to determine which yours is.
Nickel-based batteries (either NiCd or NiMH) DO NOT generally suffer from a misunderstood phenomenon known as the "memory effect." As described in Wikipedia and many expert sources,[2] the term "memory effect" has been widely mythologized to describe any and all deterioration of NiCd (and other battery chemistries), in many cases misleading consumers into further shortening the lives of the batteries through over-discharging to "recondition" them.[3]
[This section formerly read: If you charge the battery partially enough times, eventually the battery "forgets" that it can charge fully. A nickel-based battery suffering from memory effect can be reconditioned, which requires the battery to be completely discharged, then completely recharged (sometimes several times). The appropriate length of time between reconditionings varies. A good rule to follow for nickel-battery cell-phones is to discharge them completely once every two to three weeks, and only when you have a charger available. [4] ]
Lithium ion batteries can be preserved by careful charging and avoiding storing them at full charge.[5] They do not require "reconditioning."
Regardless of the battery type, use only a charger rated for your battery, and discontinue use of a charger that causes the battery to heat up excessively.

It's a shame most powerful mobiles heat up like nobody's business whilst on full chat these days.....there's no chance of keeping the batteries cool! Still, it's an expendable item and at least you can buy a replacement.....none of this iPhone 'sealed' tin rubbish.
while i find the battery life reasonable with the features this phone has (read screen size, processor speed), it will be nice to get the CPU throttling app another thread is discussing. don't need that 1000MHz running everytime i pick the phone.
On the same notes, how can i check if automatic screen brightness is kicking in?

Stick the phone under a bright light such as a desk lamp and cover the light sensor with a piece of paper.

are you the first wm phone user? Do you have good experience with phones that has so much specs? Do you use wifi and browse with phone very heavily? If you do, it is really normal that the battery will drain. My Touch HD does the same, it can last a day or 2 or drain like water not more than half a day, it depends on your usage. Try to get a second battery, or even the third one like I do, what is a big deal? It is completely normal.
I don't have a lot complaints on this phone as it meets most of my requirements.about the battery, I seriously don't think it is that bad. for example if you have a car with 1500 horse power and expect it to have or rather 30-40 mpg, don't think it is possible. try to use your local gas station (in this case your friendly charger) more often.move on with your life please.

That might be a little difficult because this battery problem is killing him, LITERALLY
Ok so I read a post that said drain your battery completely for better performance so i did.Got low bat warning and played Avatar to kill it quick.Only it didnt die fast,seemed like forever for this damn thing to really die!!!Maybe I just imagined it so I tried it again.Got low bat warning and watched a 25 min youtube vid followed by a 16 min youtube vid and several rap videos before it cut off.Try it and see how long it takes to really run out of juice and I think youll be surprised
I remembered with my G1, that once i got the low battery warning, I was always able to milk every ounce of power from that battery.
after picking up my vibrant yesterday, i charged to a full 100% with the phone turned off
i've been on it all day long, installing apps and restarting quite frequently, and i just got my first battery warning (21%)
will probably run it into the ground after work for another full cycle charge then just charge whenever it needs it. seems to have more than enough to make through a full day, and i'm only saying this because i haven't been able to put it down since this morning and it's still ticking
edit: and this is all done indoors with fluctuating 3g/2g coverage (home and work)
I have twice run my battery into the ground and charged to 100% with the phone off. Now I am getting a little over 25 hours on a single charge. this battery is indeed better than they said it was.

Better than what?
If coming from an old WM, sure, it's better.
But coming from an iPhone, which lasted for 2 days with real use, the battery of the Vibrant sucks.
With moderate use, I can's get through a full day (14-16 hours). It's the one real problem I have with this otherwise great phone.

I had two 3Gs (now have a Galaxy S and a Vibrant). It lasted almost double what the Vibrant does, with similar use.
Love the screen of the Samsung, but the battery is making me a little depressed. I am hoping that Froyo will improve it a bit.

yeah, hopefully drops sometime soon.
it seems battery life is either really good or really poor, not a lot of middle ground. of course, this could mostly be because of different peoples' opinions. but i'm coming from a dumbphone i only had to charge once a week, and so far i'm pretty impressed. like i mentioned earlier, i've been on this thing non-stop since this morning, and it's just now flashing the battery symbol at me. i imagine once i go through a couple of full cycles, and the new toy factor wears off, it will be a non-issue (for me)
what is your real world usage like?

Why not just buy some extra batteries? I picked up 3 extra batteries for when I fly so I can watch movies with no worries...
I get great battery life on my Vibrant. Make sure you turn off everything that you don't need....wifi, gps, keep screen brightness low and not on 100% at all times etc...obvious stuff....

Man, I have turned the brightness down to below stock, and I do have two extra batteries. But that's kind of like going back to my WM days.
After the getting spoiled on the iPhone, which would last for almost two full days with everything running, and with similar use, I really hate having to constantly think about the battery, and worry that it's going to die on me.
True story:
Someone hit my car a few days ago and I tried to take a pic with my Vibrant. It was in late afternoon, so the battery was at 15% I guess -- so the phone effectively told me to "F*** Off." Or at least that's how I took it No pic, of course.

I hear where you're coming from...have you tried switching out the battery to a different one? I know that some of the batteries were faulty and gave people horrible battery life.
The iPhone also ran at a much slower clock speed and it was equipped with a pretty good battery. There's no denying the awesomeness of the iPhone battery...I'm just thinking that you may have a bad battery. Try changing it out.
There's also a 2800mAh battery pack coming out very soon....it may suit your wants and needs...
The iPhone also lacks widgets and multitasking - and the screen is not as bright so those all help in maintaining battery life.
If you crippled your android in the same way - you could get 2 days pretty easily as well.

Very true...
It's like a Geo Metro vs. Ferrari ...hypothetically, if they had the same size gas tank which one would consume more gas and run out faster? It's obvious...

Come on now....
I have both, and they both have their good points and bad points.
The battery is a bad point for the Vibrant.
The screen is the best point (it's actually not "brighter", but has much better contrast than a backlit LCD). I keep the Vibrant's screen at it's lowest brightness, anyway.
But in terms of speed, there is really not much difference in daily use - if anything, the iPhone 3Gs feels a little smoother much of the time. Again something Froyo might improve.
My well conditioned battery is at 5%, after 16hrs 54 min., with very light non-call use today (calls are at 49 min. 26 sec.).
My point is, that I have to expect more after using the iPhone, while some here are obviously happy with it. But it ain't great.

We get five to six hours of display on with this phone. That number is perfect if the phone was on 35% precent or more of those 16 hours.
Sent from my SGH-T959 using XDA App
It's ALL about the apps you use.
My battery life is pretty good, I can go two days with moderate phone use and my normal heavy-e-mail and occasional messaging usage. I don't do much web browsing with it, but I fiddle with it constantly throughout the day.
My friend couldn't get through one day on his, so I encouraged him to play around with some of the apps he had that I didn't, and now he can get well into day two before it gets low enough he wants to recharge.
My wife complained about her battery life, and I realized she was pinging four e-mail accounts once per minute. Just cutting that back to a five minute interval made a huge difference.
Even so, I've ordered spare batteries and a charger since I travel often and a missed call could cost me a lot of money, and they're too cheap to not keep a few around. (In one of those other threads somebody linked to an ebay deal with two batteries and a charger for 8 bucks.)

or he's got a bunch of widgets.
That's almost universally a theme when people complain about Android battery usage.
Got my replacement Vibrant yesterday afternoon, charged it full while turned off and took it out at around 9pm. Worked on it a little last night and today installing apps browsing and about 60 min talk time so far.... 3PM and still got 30% left.
Definitely much better battery life than the one I had on first phone. I did get a replacement battery as well, but haven't tested that one yet. This one so far is working as expected.
I haven't rooted yet so I am not sure if that and lag fix has any affect on the battery.
Also ATK is not installed yet, and i hear it has adverse affect on battery. Is that true?
what do you guys see on the battery code?
G7, G8 or G9?
So up until today I've been having fairly lousy battery life (understandably) its dual core and h+..its expected..
But I read a thread earlier today (I forgot who, sorry) suggested that you go into the Latitude application and disable it and log out - ever since I did that this morning my battery has been absolutely amazing with the same usage.
It was 16 hours since unplugged from it's AC charger still at 40% which I think is amazing..just wanted to share that with you guys and suggest that you try it!
*Clarification: I normally get 12 hours and it's dead, today with the same usage I got 16 hours and 54 minutes with 40% left
Sorry for the bad grammar I wrote this in a rush
I got similar results from letting it die and get a full charge. From 10 hours to a day easy.. This thing is seriously on steroids.

So up until today I've been having fairly lousy battery life (understandably) its dual core and h+..its expected..

Its not really expected, espescially from those two things you mentioned
(btw I am at 50% .. 22h 43m 35s since unplugged)

Lithium Ion batteries are different to their predecessors in that they have no "memory effect". Other, older battery chemistry types had to be fully discharged before charging again for them to be effective and hold a charge. Lithium Ion batteries will not benefit from discharge, and are in fact ruined if you let them completely discharge. If it's a protected battery type it should shut off before it is fully discharged, thus not ruining it, but there is still no benefit. They are also very sensitive to temperature, and heat will kill them too. They will degrade at a much faster rate with heat. These are the two main reasons we have to replace cell phone batteries so frequently.
One annoyance about this phone is that it won't charge from usb worth a damn.
My previous phones I would let "slow charge" off a old powered hub overnight. With the Atrix you pretty much have to use the wall charger which charges much faster.
I swear I got better life out of my old phone when I charged it this way vs the fast charger.
Mine charges fine with USB from my laptop. I get easy 12-14 hours with 30-40% left depending on usage.

Ok seriously just google how android handles the battery stats and look for learn mode.

Don't get your point!
Lithium Ion batteries do not change their chemical make up for Android, Linux, or any other operating system for that matter.
Android "battery stats" have absolutely nothing to do with how a lithium ion battery operates, and is designed to operate. I would love for you to enlighten me on how Android changes this, as your post seems to imply Android can manipulate the chemical makeup and basic design intent of lithium ion batteries!
Protected lithium ion batteries have "protection" circuits in them much like a mini computer which can be programmed to shut them off prior to full discharge, over charge, too much heat, etc. Android can utilize this "mini computer" to prevent problems with the batteries themselves, but not eliminate those problems!
Now, if you really want to argue this, stop quoting Google, (which you actually didn't, you just said Google it!) and we will dig into the full design intent, chemical balance and makeup, and actual results of tests which come directly from the engineers who gave us lithium ion batteries. You can produce your test data to substantiate what you are saying, and I will do the same! If you aren't willing, or can't as I surmise the case will be, stop Googling, and stop jumping up and down because someone has commented something contrary to what you believe or have said. I simply pointed out FACTS relative to lithium ion batteries so people wouldn't be confused thinking the best thing to do is let the battery drain out and then charge it, because if the battery doesn't have a protection circuit, it will die!
<edit> BTW...........If you seriously want to argue this, don't comment back with something childish like a WiKi link............lets get down to the nitty gritty nuts and bolts of this subject!
btw I am at 40% .. 26h 06m 02s since unplugged
1day 10 hours 33 minues 39 seconds since unplugged,
30% left
just plugged in
I'm currently at around 46 hours with like 25% left lol. I guess that's pretty good!
Obviously I'm not having too many problems battery wise, but I was wondering, how do I disable this latitude application? When I click on it in my app drawer, it just takes me to maps... However, I installed GingerBlur, and the latitude app isn't even in my drawer anymore? Is it just an add-on of sorts to the Maps app? If so, if I've never actually signed in or anything does that mean I don't need to worry about disabling?
If you can deal with the lagged connection after unlocking and periodic checks for stuff like email rather than near instant, then JuiceDefender really does seem to go a long way in terms of battery saving.

Caelan I'm not trying to be a **** or argue about liion batteries, I know that draining it affects battery health. What I'm saying is that I read back in my n1 days that theirs a way to enter "learn mode" from plugging in your phone while the shutdown process (chimes, and the "shutting down phone") note this was all from xda and all for the n1 so I have no idea if its as simple on the atrix. I was going to attempt this but I fell asleep and it completely discharged and on the next charge it has calibrated itself and I'm experiencing much better results.
I know its not placebo because nothing has changed usage wise. Same apps same deal.
I only told you to google it because thats what I did and I can't remember what article. Cheers
** on a side note I did this on my xoom because I was having problems with bad battery after using oc kernels and continual bad battery after flashing back. And I can report 3 days uptime so far so theirs something to this.

And yes I agree that if you are simply a power user and you have a lot of weak internet connections and run your screen on full brightness you will experience very little affect from calibration but if your a moderate user that is having problems getting your phone to sleep properly and still getting 10 hours then something is wrong.
No android does not chemically change batteries but it does control how much juice is used for certain activities. I noticed that my battery would drain rapidly from 100 to 60 with little usage and having my screen off didn't seem to slow it down. From 60% it would be better but at the 20% it would take a long time to drain. After I calibrated my battery it drained only with usage and would practically stop if the screen was turned off. Hopefully that can help someone... I know how annoying an unconditioned battery can be.
Ps what caelan is saying is true so if you do calibrate don't do it often because this leads to shorter battery life in the long run.

I run gingerblur 3.5 on my atrix and it more than doubles my battery life over stock. Just plugged mine in and was 1 day and 23 hours since last plugged in. I don't do a lot of stuff with it besides text and try not to have a TON of apps running.

But I read a thread earlier today (I forgot who, sorry) suggested that you go into the Latitude application and disable it and log out - ever since I did that this morning my battery has been absolutely amazing with the same usage.

Right now I am at 1 day and 10 hrs @ 40%.
Download Elixir and load up a 7x1 widget on your home screen. add in Wifi and GPS switches. These will save your battery life the most.
do any of the users that get well above 16 hours of battery life want to elaborate on what applications may be running, widgets, etc? I have my brightness set to 11%, have 5 homescreen pages, mostly widgets that refresh hourly or longer, and hardly ever have wifi on.
basically you had your gps reporting your location all day long. No wonder you got a lousy battery life. You should have seen the gps icon on and the app being listed on the battery manager.
Just wait till exchange corporate sync goes nuts and drains your battery in 3 hours flat.

so I bought the phone few days ago and the first thing I did was to empty the battery as advised, at about 20 % I was sleepy as hell and I wanted to drain the battery faster so the first thing came to my mind (and I regret that) was restarting the phone repeatedly so it would drain very fast , and I blindly did so , what a stupid idea! I did an approximate number of 15 restarts I guess with about 2 mins between each restart, sooo I am ready to take the consequences so what are they? what should I expect for the next few days? battery failure,cpu failure, ram failure, or even software failure?? the first 2 things I notice the battery now drain a little bit faster and the phone gets warmer faster than before
I don't think this will cause any harm at all. It's not like the phone takes a voltage surge during start up.
OTOH, there's no benefit to "conditioning" a lithium ion battery. If anything, it's counterproductive. Li batteries don't like being fully discharged or overcharged. Keep it between 25% and 75% as much as possible, and it will last the longest.

OMG thank u so much I was so worried cos I have a bad history of damaging and breaking stuff especially electronic stuff so u don't recommend me to fully charge it? 75% for maximum?? and rebooting is it safe in general?
Charging it fully won't really hurt anything. The phone's circuitry won't let the battery overcharge. But the battery will probably have a slightly longer life if it doesn't get charged to 100% all the time. Battery life is good enough that I can generally take mine off the charger at around 75% and can still get a full day out of it. But if I leave it on to 100% I don't worry about it. And if you like to charge yours overnight and it always goes to 100%, don't worry about that, either.
And yes, it's perfectly fine to reboot the phone. I generally reboot mine every couple of weeks. It seems to clear out some of the stuff that builds up in memory and runs a little smoother.
No, but draining the battery does, especially draining it fast.
When will these stupid myths about a totally different and obsolete battery technology die?

now I believe it's a myth too, but hey aren't some apps like games considered as battery-hungry apps? they drain batteries so fast too!!
I hope this is a joke..

Lithium-ion batteries degrade predictably throughout usage cycles, so the more you use them the more you reduce their total capacity. They're also more vulnerable to such degradation while under high temperatures, like when you drain them very fast by restarting the device. And yes, also if you're playing games. Obviously there's no point in getting a nice phone if you're not even gonna use it, but you can choose to spend those battery cycles on meaningful usage like playing games, rather than pointlessly restarting the device.
This is a classic example of thinking too hard. Just use and enjoy the phone and charge it when it needs charging.
