This is my personal review of the exact battery seen in this auction.
http://cgi.ebay.com/Battery-For-AT-...3314352QQcmdZViewItem?_trksid=p3286.m20.l1116
My startrek is brand new. I actually owned the phone when it came out and sold it. Now I have it again once I found out that I could install WM6.1 Professional. I LOVE IT. I like rubbing it in everyones face that owns other Smartphones and PDA phones that my phone can do everything yours can do and more. Anyways I noticed that with the stock 1100MAH battery the life was kinda sub par I rarely got a full day out of it. Although the cpuscaler makes the phone really responsive. It uses alot of juice and the only way I got respectable runtime is when I forced it to stay under clocked. Even then it got me a little over a day maybe 36 hours. I surf the net. I send over 2-400 txt a day. I run OZ IM software all day. I sync my hotmail every 30 min. Plus 1-2 hours of talk time and 2-3 hours of bluetooth a2dp play time. I use Garmin and bluetooth gps everyday. So im raping the stock battery. I sprung for the extend battery on ebay vs the mugen battery of the same AH. 1/3 of the cost. Im happy to say that i get atleast 2 1/2 if not 3 days without charging. The phone has a big arshe now because of the new cover. It really feels alot more comfortable in your hand with the bigger hump in the back. I got big hands and the stock always felt uncomfortable using one hand. I can leave cpuscaler on all the time now without worring about "I NEED MORE POWER CAPTAIN!!" Actually since the phone is a little bit elevated off the flat surface it get better reception and doesnt rock back and forth like with the stock battery and cover. The cover is cheap plastic but its rugged. It doesnt quite follow the profile of the phone exactly but its pretty close. Cover still shuts off phone when taken off. Ive used it for about two weeks and discharged it fully several times so im pretty confident in my results. There is no false battery % reporting like most cheap or expensive batteries have. It has gave me an accurate % every day and didnt hang at a certain % for hours like the mugen battery did on my kaiser. This is a good buy and i suggest everyone pick one up if they are concerned about runtime and not about looks.
Hmmm, I never had a problem with my 1100mah battery, even with heavy usage, I'd have at least 30% the next day. With light usage, it will last me a few days.
That seems awfully bulky with that big back cover.
Thats kinda what i said... With heavy usage the stock battery will last about a day and a half at most. I would have about 30% left after a full 24. My extended batt leaves me with about 70%. Ive been used to extended batteries cause i believe all htc phones fall short with their undersized batteries and ive even had some phones like the HERMES that used to get 4-5 hours when they came out. As the rom cooks improved battery management they got better but still fall short. I also said if you dont care about looks and care about runtime this battery is for you. Its almost twice as large as the stock but even the more expensive battery like the mugen battery .... their covers arent always the most streamline covers. The only cover I liked on my phone from them was the kaiser only cause it appeared to be stock with no bumps or humps lol. Im not a fan of opportunity charging because i find my self buying 5-6 chargers for one phone and placing them in my various hot spots losing the phone and or charger and having to make unecessary trips to retrieve them. Its a slim smart phone what do you expect.It personally fits better in my hand. My desktop dock just came in and it fits like a champ. Fits fine in my universal fit suction cup windshield mount too. So its cool with me.
My S740 is now coming up to one year old. For various reasons I have had 2 batteries for the device which are both of a similar age.
Anyhow, normally I get a full days use out of a battery however on a very busy day I may end up changing to the 2nd battery around 5pm.
In recent weeks, every now and then the battery will be dead after only a few hours even under light use. After a full charge, it is fine again giving full days of use.
I have checked there are no programs running in the background etc and can't see any pattern to this.
This happens when using either of the batteries and is really annoying.
So if this random discharging a sign of the batteries failing or something more sinister? Has anybody else seen similar things? I am happy to buy a new battery but at £30 don't want to then find the same problems again
Thanks
I've only been using this phone for about a month now and agree the battery can be quite erratic!
I don't think it's anything to with the phone 'failing'. I've had quite a few smart phones and to be honest it just seems to be common practice for these types of phones to have a strange battery life.
Some days from a full charge I can get up to 2.5 days! Other from a full charge it will run down completely in under a day.
I'm going to invest in one of those extended batteries, the battery capacity on those is more then double that of the standard battery. Sure it adds a bit more bulk to the phone but I kind of like that, will turn it into a proper beast!!
My phone's battery-life is also erratic (and limited anyway).
Always was, but with me also more now after a year.
For me it feels a bit soon for a failing battery. Normally in my experinence with Li-ion batteries, they work well for over 2 years.
Often I can relate the bad battery-life with extensive use (calling, internet), but sometimes it's almost empty overnight with 75% at the start of the night.
I suspect a non-linear decline of the presented battery-capacity is one of the causes: while decreasing it falls faster.
In my experience it stays quite a while above 80% and after the 20% warning I only have a few minutes calling-time left.
First of all, hello to everyone. I have been reading through a lot of threads here in the last few weeks after getting my HD2, especially the ones about battery life.
I have never owned a smartphone, so I have no comparison but I'm barely getting through 1 day of use when fully charged! And I'm not even using it that much yet, Wifi is off, no data transfers, just some texting and calls. I have installed Bandswitch and Battlog, didn't really help though.
Got the phone brand new (T-Mobile US) and haven't done any major tweaking yet, it's still pretty much stock with a few programs that I installed so far.
Do you guys have a similar experience or is it completely different? I love the phone, but if I dont even get through one day of use (and I want to use the phone in the future, not just for surfing but for music streaming or web browsing), I would have to bring it back.
Any help appreciated!
It's just something you have to live with, buy a spare battery, or the extended battery, flash a lighter ROM, adjust screen brightness turn off push e-mails etc etc.
I can get 2 days battery from very light use. i.e. a few texts and calls a day, no Wi-Fi, bluetooth or internet browsing. That's just how smartphones are.
So how do you do it on a daily basis?
My battery is fully charged in the morning and lets assume I'm using the phone for what I bought it for - some music streaming, gps here and there if I need it, some web browsing, calls and texts etc.
I haven't even started using most of the features of the phone and my battery has died twice on my already while I was out at night.
How can that be normal or acceptable? I can't charge my battery every 6h...

Maybe you shouldn't have a smart phone? Battery technology is ****, it's a shame, but it's true. The only thing I can suggest is a spare battery, I carry one everywhere.
I generally watch an hour and a half of video a day on my phone, text, call, use the internet and I can still make a 9 hour day with 40%+ battery left, and just incase I am out and about in the evening before I have a chance to get the phone on charge I have the spare.
But with that said half hours charge from the mains will give you a good 30% topup I very seldom have to swap the batterys and I use a pretty juicy ROM.

or maybe not
Given his kind of use, 2 days should be normal. Right now I'm squeezing 3 days out of this battery, and that's only because I swap it out when it's at 10%, otherwise it could be a little longer... and a few calls here and there is not the only thing I did with it... it's still my work pda after all
Since it's pretty much stock, unless it gets better with time (the first recharging cycles are the worst) and even after a hard reset it won't get better, it probably is something wrong not software related.
Install battclock and check the standby battery drain, shouldn't be much higher than 4mA, up to 7mA could be normal, any higher than that, especially if significant, and you've got something wrong, and found the cause to the short battery life.
First off, buy a couple of cheap oem batteries from here...
Now, these eBay batteries have performed slightly better than the original battery...
Some of us smartphone users are so used to poor battery life we have power charging cradles at home work and car just to keep the charge up... And have spare batteries every in case of emergency...
I take my phone off the charger at 6am to go to work... My avg day is 6-10 calls, 20 reminders, an hour of UNO, an hour as a wifi router and I return home at 5pm with 50-60% battery life...
they are trying to make batteries smaller and thinner so they can make the phones thinner and smaller so battery life is compromised. But you do need to give it some time to settle in.
Back up batteries and cradles to charge them are cheap and an easy solution. So are extra chargers to keep at work, in the car, etc. Most people can charge their phone at least an hour during the day and that should give you all you need.
The only smartphone that I didn't carry an extra battery for was the moto q9c, because it came with an extended life battery. But on these phones, that probably isn't the best option.
So what did you guys do to improve the battery life of your HD2? Are there any specific programs (I heared about G-Profile) you are not supposed to use or did you guys just deinstall all the T-Mobile Apps?
If I can just get 1 day of actual use out of it I am OK with that. I just dont want to have die every second or third day if I use more often than normal...
Any suggestions or may tests I could do? I feel like I could stream music on Slacker for about 90 Minutes and the battery would be dead...
EDIT: Just did Battlog for about 15 Minutes, my phone uses between 15ma and 31ma when in standby. So where do I start, how do I find the culprit?
I love huge screen HTC devices and Im a power user, so my solutions for power issues are:

There is a 15% discount right now, better hurry.
Extra chargers and thats it! Now I browse, calls, emails, music, videos, TV stream (Slingplayer) and maximize all of the other features of my HD2 t9193.
Software and the end-user are the cause behind battery drain. I've got 2.5days out of moderate use so I don't think it's the hardware at all.
Methods for testing battery consumption and proof it is typically software related
Hi,
At the risk of looking like I'm trying to hijack this thread, I started a discussion on this particular subject a while ago as feedback on my finding after reading almost all the threads I could find regarding battery use on the HD2. Lude219 is 100% correct, the issue is always software related (yea, I know there might be exceptions to the rule) and my phone was a prime example of that.
See the thread below that explains how to measure your battery consumption, has logs and screen shots from users you have high consumption and also people who have systems where battery life is more than 48 hours so that you can compare your results.

I'm also sure it's software related. My phone would use app. 2% overnight with all connections closed. This i tested over months. Then suddenly without me changing anything drastic software wise, it pulled 5% per 3-4 hours. So after going thru all the cleaning routines nothing helped exept a good "ram cleaning" . Somehow or other the phone starts processes over time wich consume alot of power. One would have to look into it with a process manager to find out what exactly it is. WinMo seems to be quite sofisticated looking at all the running processes. So my view is , keeping the system tidy might be the only way to save the extra power.This is where the huge diffrence to other platforms seems to be, it can take quite a while until you have configured your phone the way you need it. I am useing the stock rom 1.66 German
thanks you guys for participating and sharing your thoughts.
But now, here is a thinker:
Last night, I let my battery drain all the way to zero and then recharged it at night. The only other thing I did was installing BSBTweaks and Touch X Taskmanager. I also changed my Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before).
And I couldnt believe what I was seeing, I took my phone off the charger this morning around 8.30am and now at 7pm I am still at 84%!!! I did not use the phone heavily but sent and received a few texts, made 1 call and played around with it for a little bit. Similiarly to what I did in the beginning after I got the phone, but then the battery had almost died at 7pm!
I am super happy and hope it stays like that but cannot explain why all the sudden it is that different...
Hi everyone,
This is a very usefull thread, for me it is, thanks to everybody that answered.
regrding the last post, a noobish quesition is
”Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before): how do i do this?”
I remember stumbling upon this setting the day i got the phone and started viciously going through it.
Somehow it didnt store in my memory the path i went that day so i can try doing what the man sugested.
So if anyone can lay a hand, much obliged.
Regards
i lost 12 pct over night in 9 hours with my radio turned off last night and only gmail and texts were open...
with battlog how do i do the test so it stays in standby? it keeps turning the screen on and off when i run benchmark
You may want to flash a new radio. Try a new one each day and measure battery life. I use radio 2.12.50 and have had a good experience.
yeah but with my radio turned off the radio shouldnt affect it shoudl it?
i use blackberry to stream pandora radio thru aux for about 8 hours a day and it still has 2 bars left after that.
HD2 just sits there and kills the battery lol
what kind of phone is that when you have to disable all its functions every time you dont use it?
seriously this is called unfinished product or poor design, that is beeing sold to customers as a next best thing.
you guys can argue with me all you want. i heard many excuses from users advocating the companies. such as. if you dont like this than pay more for a better product. well HD2 is a better product, its a 500 dollar phone damn it.
but you dont realize that even the "better" products suffer from same underdevelopment syndrome.
companies spend millions on consumer research and consumers spend millions on **** they dont need every year. cows eat grass, consumers eat garbage made by big companies.
where are the better products? they dont exist because it became "normal" to have a faulty OS or for your phone buttons to fall off, or battery to explode.
companies worked long and hard to make consumers get used to the idea that garbage is just a part of life, and worked long and hard to minimize costs of production, and cut corners.
which corners?
the final QA testing that is not beeing done by a company, so they can release the phone 3 months earlier, the consumers pay for the phone and test it.
we work for the company and we pay for it instead of getting paid.
the phone breaks oh how sad ,
company takes note(dont use this cheap glue or the buttons fall off, get a lil more expensive glue next year)
so they use better glue and cut another corner and we buy another "new and improved phone" and this time screen goes dim oh dang not again...and it continues.
do you disconnect your car battery every night so it doesnt die? or when you buy a lexus do you drive with your AC off because it cant pull the car around when ac is on same time as the stereo?
how long dos your battery last WITH THE SCREEN ON with and without 4g poll
I can't tell you the time without, but I can say 4+ hours with. Wifi/GPS etc. turned off however.
I can get away with charging it every second day with light use.
Now THAT IS an interesting question. Gonna try this next day off rofl.
xD
well reading over all these battery threads they brag nonstop about godlike battery life i highly doubt them and because of their incessant bragging over 2 days of battery doing blah blah people assume something is wrong with their battery. i highly invite them to take this poll and see their actual screen on time they guess that they played for 15 - 30 mins when it was only ten or so , this poll ought to straighten things out so we actually know wether these battery issues are normal for everyone.
This pool is a bit too restricting. There are other things that impact battery life... like screen brightness and haptic feedback to name two.
I can say My phone lasts, every day, from 9am to 2am with moderate use, about 4 hours screen on.
I cant turn off 4g, but on my phone I get 24hrs use with 5hrs screen time with Wifi on 7-8hrs. I use autobrightness, have next to no widgets, and a static wallpaper.
The reviews I have seen make it seem like the battery life should be much better though.
Sent from my Atrix
As the lady said in Full Metal Jacket, "Me love you long time."
In all honesty I'm a little disappointed with the battery life on my Atrix. I pretty much bought this phone as a replacement over my iPhone 3GS, because the battery would barley last 2 days with little to no use, but I can't say the Atrix provides much improvement either. With minimal use I'd get around 2 days of battery with my Atrix. Today I charged my phone at 7:30PM and with little use (maybe 20min in total) the battery is at 80% after 10 hours. Either this is normal or mine is faulty, cause the area around near the main front buttons and where the Moto blur logo is on the back constantly gets warm during normal use. I've had the phone for a little over a week now, so if I'm the only one having these issues then maybe I should go to a Bell store and exchange it for a new one.
Hi it's been a while since I have been on here. I just wanted to say that googles decision to aggressively cut back the charging as the battery fills is one of the best things they have done in a long time. I personally have used a chargie on all my phones since the pixel 2xl. For those of you who don't know what chargie is it's a device that goes between the brick and the phone and is controlled by an app using BLE and you can set the parameters however you like. I had the phone charge to 80 then it cut power and dropped 3 percent to give the battery chemistry time to settle down then it would.lick back on and charge back to 80 and repeat until I unplugged it. It also has a top off feature that you can set so you can have your phone at 100 before you go if you have a nice set routine which I do not. It also cut the wattage down to like 7 what's or something so there was no fast.chsrgine there. If I did need to fast charge I would use the 30w charger I have. Anyway chargie did not work with the pixel stand so I paied for the pixel stand and pretty much never used it. Then I saw an article about Googles new charging policy.. I gotta say I am so happy now I can use my pixel stand and my phone pretty much never charges past 79 which is fine for me. And if I need it to charge to 100 I just reset it and turn off adaptive charging. But it's very rare 5hst I need to do that. It was a smart move on googles part because there is going to be people who keep this pixel 6 for the full 5 years and if the battery doesn't last they are going to be replacing batteries constantly.
For anyone who has any doughts about this charging method and how effective not is let me just say that I have a pixel 3a xl that we got as soon as it was launched it was my wife's phone for 2 years it is now being used as a security camera. It has always had a chargie since the day I got it. And now it sits on plugged in 24/7 but I still use a chargie. Let me just tell you according to accubattery the health of that battery is still at 99% capacity. And it has been sitting on a charger for almost a year straight. That means almost no degradation to the battery. I don't.know about any of you but I find that pretty amazing.
I hope.that other phone manufacturers follow suit and build.these protections into our devices. It is good to have the capability to charge up fast in a pinch but that should be the only time it is used in a pinch. The rest of the time slow and steady wins the race. I think everyone should look into chargie it works for anything with a battery not just phones the newer ones can set a pre determined limit and not even need the app. And I in no way shape or form work for chargie I just really believe in their product.
I totally agree with you on this. until we are able to obtain the new battery tech that are currently in R&D, we have to protect the current gen and make our device last as long as possible.
I just got my new pixel 6 yesterday and for the first week I'll be charging it to 100% back down to about 20% to check it's capacity and to get an estimate how long it could last me with my usage if I ever need to be away from the brick for some time. Accubattery is also running to put it all in numbers for me.
Once this is done, I'll set adaptive charging and let it charge to 80%, then unplug. I don't have the habit of charging while sleeping so I'll use 80% as my max normal ceiling. usually adaptive charging will slowly top it off to 100% just before your alarm goes off in the morning but i prefer leaving noting plugged while asleep...can never guess when those things might explode/cause fire.
Fun fact: samsung also has this thing in their settings now. they let you enable 85% charge. once enabled the phone restarts and still shows 0-100% but in reality charges the battery only until 85%.
Referring to stuff made out of graphene?
I'd love to see graphene supercapacitors for powering phones. While they have somewhat lower energy densities (1/2 or 1/3 capacity vs lithium), they're light and would last virtually forever. I'd happily double the thickness to get this.
However, the industry is probably going to lean towards graphene batteries. Substantially HIGHER energy density than lithium, and generally performs better in almost all areas, but its still a chemical battery.
So last a few weeks on a charge? Or charge instantly whenever you want? Either would be a lot better.
Battery tech has a long way to go IMO.
I mean we are making power with rocks. Kinda says it all.
I practice these same things to extend the life of my rocks
