I've had my Flyer a few months now and in the last few days the battery seems to be draining very quickly. I charged it full again last night and this morning it was at 88%.
I've turned everything off so just the bare bones of the device are alive and i'm using Juice Defender, and still no joy. It's only started doing this in the last few days so i presume the battery is on the way out very quickly.
I've let it drain to 10% and charged it, and it's made no difference.
I'm not going to mess about with settings and more waiting to see what it does etc...., I really just want to get a new battery and be done with.
Where can i buy a new battery? I've had a look on fleabay and no joy.
Any suggestions where to get one, part no. etc...?
Many thanks in advance

happened with me also....10% battery drained overnight...
what app is using most of ur battery?
sometimes push service in some free market apps drains a lot of battery and it keeps running even when app is closed... check running processes... well i uninstalled that app with push service and all became normal
Thanks for that but i've had a look through and it would seem that there isn't anything happening over night that i'm not expecting or that is being very hard on the battery.
I'm pretty confident the battery is the culprit here. Sourcing a new battery however is proving to be a problem. Somebody somewhere must be selling them.
I've just been on to HTC in the UK, they have a service centre not very far away from me and they won't sell me a battery or even give me a part no. for the battery.
Come on, somebody must know where to get one.
I think i might have found somewhere in China...

If the prices were cheap enough how many of you would be interested in buying a battery for your Flyer.
Perhaps do a group buy?
i thought flyers battery is not user replaceable?
It's very replaceable and easy to do.

I'm going to have to look at getting a new battery sooner or later. It's getting to the point hat the battery is always running low by the time I get home in the evening or even running out. With pretty much the same use it used to be good for a day and a half easily. Flyer was purchase may or june 2011 so it really needs to last another 16 months or so.
Well......I ask again. If anyone knows of where to buy an internal Flyer battery please post a linky.
I posted this thread earlier today
"I just wanted to know what people are getting out of their batteries. I unplug mine around 7:30 am when i leave for work. When I get to work i turn on my wifi (rooted thunderbolt) and leave that on all day. I have the setting to turn wifi off (flyer) when screen is off. When I get home around 5:30 i switch to my home network and by 8-10 my battery is pretty much gone. Is this normal battery life or are there any tricks I'm not aware of that will help with battery. My wife has an Ipad 1 and she seems to get days of use out of it before she needs to charge it.
Also, I don't watch movies or video at work... most of my use is surfing, twitter and email."
I'm trying to figure out if what is normal battery life and If mine came with a bad battery. If so Yes I would be interested in getting a new one.
The Ipad battery has much longer life and is a much bigger capacity battery. The new HTC Jetstream also has a much bigger capacity battery as well. I think HTC have learned lessons on how much battery power these flyers use, but unfortunately have used Flyer owners as guinea pigs, rather like the first Apple iPhone but that had terrible battery issues as well although they've gotten better over time.
When my Flyer was brand new the battery lasted for ages and i couldn't understand what people were on about the battery not lasting for very long. So up until a few weeks ago my battery was doing fine and then almost within a day or two the battery started to run down quickly and has been doing so ever since. I've since loaded/unloaded new ROMS and done all the usual procedures for deleting the battery stats etc..., and still no joy.
I think the problem is with the battery not being man enough for the job at 4000mAh, and the drain is such that the battery is being worked hard since September last year (in my case) to a point where it is now progressively failing. I'm not so sure either that it's all that good in terms of quality.
Most of that time it has been charging from one source or another. If my Flyer isn't in the car or in the house it's not often being used battery only unlike most other people probably use the battery only a lot, so i can't understand why the battery is failing when it's not even that old.
This is a big issue with the Flyer and for what the device cost i would have expected a lot better. I think the Flyer in itself is a fantastic piece of kit that i will no doubt keep for a very long time as i did my XDA IIi but i never had problems buying another battery for my IIi. HTC will not sell me a battery, they insist i send the device to them and they will swap it but will cost about £50-£60 for the pleasure. I flatly refuse to pay that!!
What is required is a bigger capacity battery (6000-8000mAh) in the same packaging as the current battery however, i think for now i would happily settle for another of the same battery if i could just get hold of one.
So far it's proving an impossible task!!
Just to add: Once you've made sure there aren't apps being opened at startup that don't need to be opened until you're ready to use them, also make sure wifi/bluetooth, mobile data is all off when not required, and all the usual tweakes to make sure animations are off, screen is on the lowest brightness etc..., then there is not a lot more you can do. I don't know how much use something like Juice Defender will be as that only makes sure your data connections are off at night and other times you specify. I've tried it and it didn't help at all so i don't know what else to suggest apart from turning the radio part of the phone off completely at night if it isn't on charge.
If i leave my phone off charge all night, having fully charged first, i wake up in the morning and it's down to around 86-88% battery.

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.
I've ordered the non oem "2000mah" battery from ebay... since im in south america it might take a while to reach here, anyone has it? please share your thoughts!
i also buy from ebay this battery, i'm waiting from 2 week, i hope arrived quickly
Same here... I've ordered my 2000ma battery from ebay and I'm still waiting the delivery...
In our italian forum there's already some persons with this battery and from the first information that I've read they've good result.
I'll perform some test once I'll have the new battery
Hi,
I have the 2000mah battery and are very happy with it, but have read some posts from other users that claims that there is no improvement over the original. Not sure exactly how much longer stand by time I get with this battery, but it is a significant improvement from the original battery
Ordered too on 16 January on ebay, but still no arrived..
Battery
It appears to have no more power/longevity over original battery.
To me, the way to stretch battery life is to use a task killer often.
Does anyone know of a charging stand that is available for the Liquid?
I have this battery. I need to test it better but it is worse than original.
I'm going to run a more scientific test today
On the Original Battery, charged to 100%
End All with Advanced Task Manager (cept for some excluded tasks)
Turn on wifi, BT, GPS, brightness on max, using 3G
Media server App on
Swiftp on
Sygic mobile maps turned on
After the phone dies, ill record the time
Then charge up the Extended battery and do the same
So far, cycling the new battery for about a week, it seems to be about the same in capacity as the original
Tests results in
the original lasted pretty much exactly 3.5 hours
the extended lasted 3.5hrs as well
testing charge times now
sigh
have u got the rest of the tests??
mine seems like never arriving!
So really the 200 battery makes no difference?
Dissapointed was thinking of getting one
The thing that seems to drain my battery is the WIFI and web stuff
There is a thing in setup to tell you what has been using the battery but I dont know how accurate it is??
Pete
ok, after a thorough testing, what do you think??
Anybody seen results because it is getting hard to use it with this current battery life

I have sign a few posts on the battery from mugen that started that if you want a real change in life that you have to use the 3100mah battery. With out you will see almost 3x the battery life. I'm wanting to try it myself but kinda saving up pennies here and there to buy it.

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:
Callpod Fueltank Duo

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?
Searched to see if this was already asked but didn't it.
Are the batteries in the Vibrant, Fascinate and Captivate identical. I need to get a spare battery today (if possible) and although the specs indicate it is the same exxact battery, I figure I'd better check with more knowledgable people.
Still trying to work out how to get a full day (8 hours) out of a charge (my only major complaint about the Vibrant - it is a great phone).
Thanks!

I know they are between the fascinate and the vibrant. My wife has a fascinate and we switch batteries all the time when mine is low.
Unfortunately I can't seem to find one at any retail stores. Tried a compnay owned AT&T and T-Mobile store (they had next to nothing as far as accessories) and Best Buy and Radio Shack.. Nada.. Guess I have to wait for the one I ordered from Amazon.. Really need one for Monday. Oh well.
Maybe I can conserve battery life by not using it :-(

This may be a bit extreme, but I've had much better battery life after switching to this custom ROM...
http://forum.xda-developers.com/showthread.php?t=782027
There are other tips as well, such as having your email check every 30 minutes instead of using "push" email, etc.
This is my first Android phone and I'm not comfortable (yet) with updating the ROM.
Without push e-mail, I may as well go back to my BlackBerry. I am already giving up Office Communicator and I can't give up push e-mail.
Unfortunately this reminds me of the early days of the iPhoney; battery life was dreadful there. Difference is, I like the Vibrant. And it has a replaceable battery.
Downloaded and installed JuiceDefender and purchased UltimateJuice. See how they work. Seems like a lot of work (between that and shutting off WiFi and BT and then remembering to turn them on). So it goes.
So far, battery life has been a disappointment.

I've always read that push was significantly BETTER for your battery than checking email at a fixed interval.
This is now depressing... Battery was 100% charged; 90 minutes later it is 70% charged. No phone calls. Very few e-mails (and I get a ton during the week). Two text messages. 10 minutes of web browsing...
So now I am uninstalling apps that I wanted like FaceBook and Twitter to see if I can find the major drain. And I won't be able to so I'll have to go back to my old phone. Very depressing. I checked with someone else in my group. Same thing.
How do people who need push e-mail and IM deal with this? I am 100% positive it will get better in the future, but I can't wait
Check ebay. I got two batteries and a battery charger for around fifteen bucks. Works great....also try calibrating your battery meter by letting the phone completely drain then completely charge it. Doing that a few times every now and then defin helps my battery meter

Extended battery
I bought an extended battery from mugenbattery.com. It's for the Galaxy S i9000, but since both that phone and the Vibrant are practically identical inside and out, it fit perfectly. After unplugging my phone for about 8 hours, after light use (bluetooth on for about 30 mins and a few email checks), my battery was down to about 92%. With the stock battery it was down to the upper 70's. Also all the gel cases and leather cases for the i9000 will fit the vibrant (i have one of each). Mind you, the phone with the extended battery will feel heavier and will be about twice as thick, but I don't care. I got juice now for pandora and angry birds all day baby
I was wondering when someone would recommend getting a new oem battery for the eris? I've had mine for almost 2 years now and it seems like my phone dies quite quickly. Of course my usage varies (usually depending on if the girlfriend is working lol) so i can't be sure. Furthermore its not like i kept logs of my battery life when i first got the phone so its not like i can accurately compare to my past life. What do you guys and girls think? The oem batteries on ebay for like 5$ are quite tempting at this point.

I was noticing definitively lower battery life in May this year - so, when my battery was about 16 months old - and bought a new one, and battery life definitely improved back to my old normal. I had to weight that against the realization that I was planning to upgrade my phone sometime around mid-August to late-September - but it was still worth it to me. It's a lot less of a hassle than making sure that I am charging a couple of times a day.
I think that, given the charge cycles that phone batteries typically get, this is pretty much expected.
Do it.
Also, there was a thread around here somewhere (in the Droid Eris Q&A section) about OEM batteries for about 10 bucks. I'd say that's a pretty good deal.
Alright thanks, i jumped on it, should be here by monday. Ill let you all know how it goes

You should be fine with it - especially for under $10 - I ordered a HTC Ozone OEM 1500 maH battery for the Eris (which I knew would fit tightly with the stock cover) and nearly 6 months later, no issues whatsoever & holding charges. Recently ordered a LG ENV3 (OEM) battery from the same NY-based eBay merchant and it put new life into DW's 2 years old "feature" phone.
I kept the "old" battery charged & keep it alongside with the headphone & usb cable handy when I'm on the go for contingency purposes, occassionally rotating between the 2 batteries.
I've had my Droid Eris for almost 2 years and noticed the battery life was becoming horrible. To the point of having to keep the phone plugged in all the time. I purchased a brand new oem battery and STILL have the same issue. Now its worse those, it will suddenly die and when I restart the phone, there is NO charge. Any suggestions?
Did you try calibrating it?

I had my battery die on a hiking trip (I was using the camera a lot) and bought a spare battery when I got home.
Not long after that I rooted my phone and put Setcpu on it to lower the clock speed when the screen is off. I now get about double the battery life. I have yet to need my spare battery, but I swap back and forth every few weeks.

I highly recommend using it as you can check to see what's running in the background (i.e Maps did manage to stay on or come back - maybe, delicate touchscreen issues ??) that might be "draining" the battery - even after a proper calibration & several full charge/discharge cycles.
Depending on the custom ROM, it could be the widgets, clock/weather/news app, email, or even screen settings, etc. Up until last week, I had a nearly 30 months old HTC battery (from the Ozone @ 1500 maH) in the now decommissioned, WiFi only Eris and it was fine - holding a solid charge for typically 20+ to 30 hours of light/moderate usage & standby time.
