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
I thought I'd write this thread simply to see if it can work for others.
I have read throughout this site that it's good to allow your battery to become completely drained, and then recharge via the power adaptor. Some people even suggest to do it 2-3 times.
Yesterday, for the second time since I bought the phone several weeks ago, I decided to allow the battery to become completely drained. I then charged it using ONLY the power adaptor.
Results?
Before, when in standby mode, no radio, wifi off, screen off, I would lose about 1% battery power per hour through the night while sleeping.
This morning I was shocked. My battery was fully recharged just before midnight, and when I woke up at about 9am this morning, I had lost only 2%. Yes, it said 98% charge left.
WOOHOO!
Anyway, I guess it really does help to allow the battery to drain and fully recharge a few times in the beginning.

I seem to read somewhere that Lithium-ion batteries don't have to be drained to be charged properly. Moreover, it's just okay even if you keep on charging it with the green light on, i.e. reached fully-charged level. Well, I myself just got the HD2 and am pretty satisfied with its battery performance although I haven't really monitored it closely. I just charge it whenever I can.
I recycle my battery about once a month and it really helps.

You are right that it's perfectly acceptable to continually charge the HD2. You can't hurt the battery. I'm just saying that I tried this suggestion (from many other threads) and it seemed to improve my battery situation. It may not work for everyone, but at least it's something.

Peter,
This is the way to treat batteries if you want to get the best performance out of them. There are numerous posts on this issue on here but it does not matter how many times it is mentioned, people still don't read.
What you get is a load of comments about how poor the battery life is without them going through the conditioning process that will get the best out of their battery, irrespective of what type of battery it is.
It is always advised that you go through several cycles of full charge and full discharge, preferably when the battery is new, to get best results, and to do this on a regular basis throughout the life of the battery.
Undertake a good deed for the day; spread the word!

You're right. I've read so many different opinions on this matter, including a lot of research on the Internet. There really does not seem to be any consensus on the matter.
One thing's for sure, I will continue to cycle through full charge and full discharge on a regular basis, perhaps once a month. In the meantime, I'll just top it off every day.
Thanks.

There is a more fundamental point to all this.
Its not the charging and discharging that makes the difference.
Its the working of the battery under load that allows the barry to achieve maximum capacity.
And constantly discharging/draining the battery will have a negative effect over time, shortening life span and usability.
Just charge and use as much as you can.

Strange that all previous phones I had I charged the same way - drain then charge for 12hrs first three times, and then drain / charge as I go - and battery always lasted satisfactorily to me ... I know it is a li-ion battery but for me it works every time and I am sticking to it until they invent better longer lasting batteries
What happens when you Recycle them tho Do you not have to buy another one as I see there not cheap.

I think he/she means re-cycle as in a charge/discharge cycle
I recently bought a HD2 and was reading very differing advice concerning teaching maximum battery capacity.
-do not let the battery go fully dry, it might harm it (source: wikipedia)
-cycle the battery, drain and fully charge a few times.
-charge as often and much as you can, the battery has no no memory, top it off as you like.
So,,,
I take it now, that the battery likes being used hard, especially when new.
Drain to 7% or so, recharge, drain till 7% or so, a few times.
So do not try to find energy saving mods in the beginning, but work it hard.
I noticed I get a huge battery drain increase when I set the screen backlight to 100 instead of 40. and what a nice display it is
So I figure thats nice way to get to know the HD2, to use it hard and bright, until the battery is 'conditioned' and I know what programs I love the extra brightness in.
I have not been able to drain the battery in a day of expected use yet, always had 23% left or so, which is almost a 4th..
Oh and sorry for off topic, but are any of you guys interested in the ebook reading capabilities on the device at all?
I use a free ebook reader called 'freda' on 'night mode' with black background and red letters, and due to the screen size it is so easy to use the HD2 as an ebook.
I snug into bed and read like 50 pages of an ebook and maybe drift off and the device will auto goto sleep too, if I go first.
It's great.
Ok my gf has gotten the surround for xmas. I wanted to see others battery usage. In essrnce how long does your battery last. Hers seems to die pretty fast and was curiuos if this is common for these phones. I would give an estimate of the time but cant atm bit will tm.

Lots of complaints on the web about this. I've had mine a few days. In my experience, like all smartphones, doing a lot of stuff (like, the things you'd do with a new phone the first few days you have it) will drain it quickly. Once you settle into a normal usage pattern, you'll probably see an improvement.
The "bad battery life" complaint always seems to come from people the first few days they own a phone and are basically turning it on and fiddling with it every 30 seconds. When used like a smartphone is normally used, you shouldn't have a problem getting through a full day with it.
Oh i know bout battery life. I got the incredible. Only 12 hours charge(but i use alot).
Thanks for the response though. Just seeing if the fast battery drain is normal for this phone. She is deffinately not a heavy user besides txt. But it seems a fast battery drain is normal. So its cool
Do you use a battery charging technique called "bump charching"?
Sent from my ADR6300 using Tapatalk
Battery gets conditioned as you use it. Just keep using it and in about a week you should get normal battery life. The issue is that the os handles both charging and discharging so after a few uses the battery and the os reach its peak performance
I believe it is alteady beggining to condition. She's just not used to having such battery drain. Its seems more stable in its level of drain. I also had her "bump" charge. To get a full capacitu battery. I notices these phone only have a 1250mwh batterys.

Battery life is horrid compared to the Fuze. I get anywhere from 12-14 hours before needing a recharge and I have been several charge cycles. I suggest turning off data connections when possible and using wifi.
Better Battery life
My htc surround also consumes a lot of energy. So today I entered in SETTING > CELLULAR > and turned OFF data connection. I think this is change may save a lot of energy, at least I can use this strategy whenever I dont need the data connection.
Lets see what happens
1500mAH Batteries on eBay
The stock battery that comes with the HTC Surround is only 1230mAH (or something on that order). There are several sellers on eBay who sell an aftermarket battery like this one: cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130467721933, which is actually a package of three batteries and a charger for $12.99 with free shipping - perfect for me and my wife to use and always have a freshly charged spare.
These batteries should give a little better than 20% improvement in battery life over the stock one. Does anyone here have any experience with them?
Sorry for the cut and paste link - as a new user I am apparently guilty of spamming before I had even thought of it (like Minority Report).
As of now she gets between 2 to 3 days use with medium txting.
Can any body else report on their battery lifes.
Also has anyone bump charged and seen an increase in their battery charge.

Good Battery Life
I use my data connection constantly, never shutting it off. Also, I spend about half of my day in the center of a building not getting any reception, consistently going from an area with service to one without, which has the phone searching endlessly for a signal. For the first week, the battery was drained within 12 hours, but now in the second week, I have about half of the battery left when i get home, play games, check email, do EVERYTHING, and probably have about 25% when i get into bed and only plug it in as I go to sleep. On previous phones, I would have been able to do this two days in a row.
I came from a Tilt 2 and ended up getting an extended battery (making the phone HUGE), though I see no problem plugging the phone in every night. Battery life is getting better and I'm not sure who NEEDS to go multiple days without a charge. Either you make your phone huge, or you plug it every night right next to you anyway.
I am very happy with the phone, and can't wait to do more with it.
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.

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.

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.

Can we go for a few beers? I think we would have some f**ked up conversations followed by more beer drinking! LOL

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

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.

Didn't find a main thread for silly questions such as this so hope it wasn't wrong for me to post this here, but I currently find myself in my phone going as low as 50% on a daily basis and I charge it next day at not lower then 40%, will this wear out the battery? am I really supposed to charge it when it's really low? Thanks.

The latest in Li-ion batteries, as the one in our phones, one duty cycle is when you use 100% of the charge.
That is ifyou go from 100 to 0 that's one cycle.
If you go from 100 to 50, recharge and again 100 to 50, that's one cycle.
Batteries wear out depending on the number of duty cycles. More duty cycles, more wear.
So what you are doing will not wear out the battery.
Also I'm not sure about this, but it is recommended that newer batteries should not be completely discharged.
Please correct me if I'm wrong, anyone else who can confirm.

Modern batteries are not like older (10 years+) batteries. I'm not about to write a wall of facts here etc. etc, but I only have one thing to tell you:
Use your device, and don't worry about the battery. It'll do just fine until the day you decide to buy a new device. Now stop worrying and just use it.

Same here, these batteries are tough. I am anal about my phone battery being charged. Haven't had an issue for years and I expect the same performance out of my S7E
Topping up your battery before it is fully discharged is the best way to extend your battery life. Modern batteries run best between 40%-80% charge. Minimize the number of times you fully discharge the battery as that is more likely to wear out the battery, although it is ok to use it until the phone shuts off once in a while.
Very impressed with the battery of the S7E. I charged to 100% last night and didn't charge until just an hr ago and was at 47%. Normal use in the morning til now. In n out of meeting, so its doing its job.
Now back to the topic of this thread, i've read some say these newer batteries should be power cycled at least once a month. Any one recommend that or against it? Haven't done it myself but did it a few times on my iPhone 6 Plus and that thing had an awesome battery even though its actually smaller than the S7E. Thoughts???

I've seen it recommended as often as once per month or as infrequently as once every 3 months. The general consensus is that it can be beneficial in that it can correct any issues that the phone software has in determining the battery's capacity, not that it is actually helping the battery itself.
Yup, I did that once in a while with my previous device (a Sony), and the battery on that one is still very good after nearly three years. I wouldn't do it that often though, but it's useful to do it when you notice the battery meter hangs on the lower numbers (like if 10% hangs for an unusually long time) or you've just flashed a ROM. The OS tends to get a little confused after some time, so it's okay to do it to "calibrate" the system again.
Thanks for the helpful replies guys.
Draining a Lithium battery to zero is one of the worst things you can to an Li battery. Don't do it. Period. Ever.
Yes, don't power cycle a battery. It MAY help give a more accurate battery reading, but it's messing up the longevity.
