for those who have it how long does the battery last with a normal use?(calls,sms and internet)Thank you in advance
No exact figure but I can easily go a day without charging and that's using BT carkit for over 1 hour. About 10 calls - 30 mins total and about 10 SMS.
Sometimes have wifi on also in the evenening to use Agile Messenger.
Gav.
Well the other day I web browsed for 10 minutes over UMTS, watched a TV show for 30 minutes, video called for 30 minutes, played games for 30 minutes and at the end of the day I still had 50% battery left.
Thats great!thank you!

Whoa, I can't agree that battery life is good because it depends which model you have and what software you use with it. I have a week old Cingular 8525 with Goodlink in a UMTS area and I get only 14 hours of battery life with low-moderate use of email alone. I turn it on at 6:45am each morning and power is down to 10-20% by 7-8pm and I've barely used the phone. Not great battery life compared to my 8125, which never died, even with heavy voice and Goodlink email usage.
I haven't traveled with my new 8525 yet but when I use it with heavy calling, I'm sure it wont get more than 12 hours, tops. I just bought a second battery because of this. I know battery life with Goodlink on the 8525 is a known issue, and is one of the reasons Cingular delayed its release, but it's REALLY BAD. I have a feeling Cingular is going to be getting more than a few 8525 returns because of poor battery life. If you use Goodlink on the 8525 you 100% need a second battery using the stock ROM.

i can concur that my 8525 has horrible battery life, i take mine off the charger around 9am, i dont really make calls, but do use pushmail, and some internet usage, mostly text and email, however mine is usually in need of a charge by 9pm when my low battery alert is coming on.. this is mostly in a UMTS area. My 8125 had far better battery life than this... oh the price we pay for speed
Exactly! That's why I bought an extra battery!
Love the 8525 speed, hate the battery life. I thought Goodlink was the problem, but it sounds like it just adds fuel to the bad battery problem.
If/when an updated rom from cingular comes out, I hope battery life will be the primary fix...
I think its the UMTS thats killing it.. i work in a UMTS area and thats where i see my biggest drain, when i am at home in a Edge area my drain is not nearly as huge, but still a bit more excessive than my 8125

Just my 2 cents: I too believe that searching for/acquiring/holding a UMTS signal might be the cause for such rapid decline in battery power. However, to be fair I must state that 1) I do not live in a UMTS area, but have read similar posts elsewhere 2) I'm a total WM5 newbie(came from a Treo 650 and Moto Razr 3)Am looking forward to travelling to a UMTS area(Texas for me, I live in Oklahoma) to find out if it's all true. Speed/battery drain, etc.
However: I must add, that just this morning. My battery went down to 30% after 3 days usage. No push email/Good, etc. Heavy text messaging, some browsing, and even one phone call that lasted 59 minutes, over speaker phone. Not to mention the other calls, an occasional game of solitaire or bubble breaker. This possible issue is probably why Cingular is looking to release a larger battery in the future, but for me(right now) mine is ok for where I live and what I use it for.
i use my hermes in tokyo umts area and have connection always on for my push mail. i receive around 60 emails, a bit of occasional web browsing and less than 20 minutes making/receiving calls a day. i only turn on wifi and bluetooth when i use them but that's not everyday. i tend to agree that the stock battery life is not good enough as it will go down to like 30% in about 12 hours in my case.
i know that umts and connection always on are draining the battery but that's how i want to use it. instead of carrying a spare battery, i decided to purchase Mugen's 3000mAh battery and have started using it from this morning. it's really good as it still shows 80% left even after using it for over 10 hours already since i tooked it off the charger this morning.

Hey! Are they available for sale now? Are they in stock? Can you please advise of the website that you used to purchase this battery from? I'm assuming that it comes with the back phone cover, correct? Thanks in advance.

I don't believe they will ship to overseas though. just send them a note to confirm. it comes with the back phone cover if you mean it by the replacement battery cover. check it out your self at the site.
I'm only getting 8-10 hours on my TyTN. I'm going to be taking it back!

Hi Harry- could you post a link to a site to purchase the Mugen 3000mAh battery.
I was searching around and found a 1500mAh battery on Seidioonline (link below). I think I read somewhere (on this site) that advertised power and actual power are 2 very different things, but am encouraged that you are getting 10 hours and are still at 80%!

i'm still at 60% after running it for 25 hours without charging. i'll have to fully discharge it 3 times at least before achieving the stated capacity so i'll have to leave it uncharged for another day. what i'm seeing is definitely more than what i expected.
the link to the site from where i purchased it is pasted in my post above.

That 1500 mah battery at Seidio Online seems wonderful, but I couldn't find any references or review that comment on the following:
- If it is compatible with the Hermes (8525/TyTn/etc.)
- If it truly provide 11% more talk/standby time
- If charging it with original Hermes charger will damage the phone in anyway or just simply taking longer to charge.
If any of the above is OK, I'd buy it in a heartbeat and make the original 1360 MAH battery my 2nd battery.

it is compatible with hermes so you don't have to worry about its compatibility. i don't believe it will damage it with the original hermes charger as i have used it for sometime.
with that said, don't expect any significant difference as it has only 150mah advantage and i couldn't even recognize the difference. i don't think it is worth spending the money unless you just want to get a spare battery but just the stock battery is way cheaper for a spare. i recommend all to go for the 3000mah one from mugen if you need longer battery life.
so this weekend i am off work and live in a non 3G area.. and all i can say is what a difference there is in battery consumption.. my phone has been off the charger for almost 6 hours and have had moderate usage and i only just recently hit 90%.. now if i was working today i would have already been at the 50-60% range... For my device i can say that 3G kills my battery life... actually i think my battery life in an "edge only" area is very comparable if not better than my 8125.. but in a 3g area i would get better battery life if i just shorted out the contacts on my battery (newbs that was joke, *DO NOT* short out the contacts on your battery)
I have the Seidio battery. It fits but not as well as the original. The cover bows up slightly when it's installed. Performance is slightly better than the original.
Average business use, couple of hours of calls , some web browsing, push email on, about a day and a half with standard battery.
HTC644 Vario II
Hi people,
I have recently dumped a Omnia2 for a Desire, just to try Android.
Although it's a beautiful phone, battery life is [email protected], so I'm considering a come back to WM, maybe to HTC HD2.
But before I make my decision, I want to know if the HD2 battery can last for at least 40 hours in my normal usage:
- 40 minutes of phone calls (made/received);
- 90 minutes (1,5 hours) of listening to music over bluetooth, using a bluetooth stereo headset;
- Auto-sync weather every 3 hours;
- Auto-sync email every 3 hours;
- 10-15 minutes of internet browsing;
- Manual sync of my Google account to update agenda and contacts twice a day.
All connections are made using 3G, I'm over a 3G network all day long.
With this daily usage, I got my Omnia2 running for about 65 hours! Let's say, almost 3 days long! I even left it on all night long, without worrying with the battery. Each day consumed 30%-35% of battery juice.
With that usage in my Desire, after one day 45% to 50% of battery juice is gone. I have to turn it off at night so I can use it the next day without recharging. It's about 26-28 hours of total usage before I have to charge it. I don't know if this is normal, maybe I just got spoiled by Omnia2 battery.
What about HD2? Does anyone have a similar usage? Do you think that if I use a HD2 that way, its battery will last longer than Desire battery?
If I had usage like that I wouldn't carry two batteries around with me Music trashes my battery and takes usage above 300mah which in theory is just over 4 hours and I listen quite a fair bit. The desire has a larger battery than the HD2 anyway and I don't think win mo has that great power management.
Hate to be the bearer of bad news, but i seriously doubt that you will be happy with the HD2 battery performance (based on your usage)
im sure you're aware there are many threads re: the poor battery issue, personally i use my phone much more conservatively than you do & struggle to get more than 1 days use (usually 30% charge remaining by the end of the day).
i mostly use edge (switch to 3g if i want to download large email attachments/ web files or watch online vids)
all updates are manual & wifi & bluetooth switched off.
i decided to stop worrying about the battery some time ago & invested in 2 spare batteries. its not ideal but in this case i think the pros of the HD2 out weight the cons.
probably not what you wanted to hear, but this has been my experience, maybe someone can offer more positive feedback.
however if you like winmo, im sure you wont be disappointed with this excellent phone.
all the best.
battery extender
you could try a battery extender like the just mobile gum pro that i recently bought for UK £33 shipped. it's Li-ion with a capacity of 4400mAh, sufficient to fully recharge my hd2 2-3 times from flat without the inconvenience of having to pop the back and soft reset the phone as you would swapping in a spare hd2 battery.
wow, sorry to say this but hd2 is no match for your usage

that is interesting. How long does it take to recharge the phone???
See this thread
Hi,
Take a look at this thread -> http://forum.xda-developers.com/showthread.php?t=718173
I regularly get more than 48 hours out of my battery but then I down listen to music much and definitely not via bluetooth so I have no idea how that would affect battery life.
I dow however use my phone a lot for reading ebooks which mean the screens on for extended periods and I still get to 48 hours +.
I'm busy transferring audio books to my phone so will be able to report back soon about extended periods of audio listening but that will be with the wired headset.
Regards

similar to the mains charger -- a couple of hours, and you can use the phone while it's charging (albeit slowing the charge rate). note: this is using the htc-supplied sync cable to charge which might be limiting the current draw to 500mA. the gum pro is rated for 1000mA output and i've just ordered a mini-to micro- usb adaptor with the data lines shorted which apparently fools the phone into thinking a mains charger is connected so that it may draw more current and charge faster still.
i forgot to mention before that the gum pro is relatively small and light -- think the weight of a pack of cards and about 2/3rds the size.
I do;
30min calls a day
1hr wifi router
30+min video playback
20 reminders a day (sound n vibrate)
All net updates every 30min (twitter, 3 emails, weather)
6am off charger - 6pm back on charger and usually has 40-50% battery life...
I reckon the HD2 would come close to your needs but there would be no margin for error. If it did what you asked the battery would die doing it...
I don't get people who want a phone to last 2-3 days...
I mean, don't people sleep at least a few hours everyday (during which the phone could recharge)?

It's a very good battery life you have there. I guess it would fit my needs.
BTW, you are on Telstra operator, right? If I'm not wrong, Telstra has 3G 850mhz. Wouldn't this better battery life?
Just installed JuiceDefender and I am now getting ALOT better battery life. I also don't think signal effects it because I am in a low signal area. One underneath on the widget is time since last unplugged, and you can see in notifications area the %'age of battery. Have been playing music, browsing internet ect, just using it moderately.
i36.tinypic.com/73ed10.png
Best record so far before getting down to 10% battery life is 25 hrs 48 minutes.
Sheeeiit. I'm lucky to get a full 12 hours on a single charge. So far. Only been through three full battery cycles so far.
2 days without problems.
Surfing, calling, WiFi, playing games, camera.
With really heavy usage like massive calling and browsing, it's was drained in one day.
Not long ago, first day low usage (FM radio, a bit od camera usage, couple of calls), lasted three days with 20% left.
nahhh ... i guess u r using a Mugen Power 3200mAh extended battery
otherwise impossible ..
wat firmware, rom, lagfix , progs are u using that gets u near to the end of the second day??
The biggest battery killer is 3G. Turn it off when you don't need it and you'll get quite nice battery life boost even without installing annoyances like Juice Defender. With 3G, my battery lasts hardly a day of light usage. On 2G, I can get two, maybe three days of light usage. Most of the time I don't need the 3G speed anyway, 2G is fast enough for a lot of things.
You might also try deleting battery stats and/or leaving the phone to turn itself off and then letting it charge until it tells you it's fully charged (you may turn it on after you've connected it to the charger, but not before that!). That way you'll calibrate the battery meter to your battery capacity properly, so it won't lie to you.
Oh yeah, and contrary to battery theory and logic, your battery WILL improve quite a bit after a week or two. Three cycles is not enough. Just be patient, give it time.
how do you switch from 3G to 2G? noob here.
Settings, Wireless, Mobile networks, Network mode - GSM only is 2G only. WCDMA is 3G.

Stock battery, G7.
You can see in my signature which ROM I am using, it's stock JG5 with no lagfix.
First couple of days since I bought it, I was very disappointed about battery life (previous HTC Touch HD lasted 2-3 days).
I came so far that I set wallpaper to black and even then it didn't last much more than one day. After some time battery life extended and it became quite better, even with Nexus live wallpaper.
3G is OFF in my case, I am mostly on WiFi when I need connection, but GPRS / EDGE are always ON.
I use 3g and battery is ok unless I play games.easily last 2 or 3 days on standby with a few short call s
1h Or 2 With games lol
I have quite bad 3G reception at home, living out of town.
At work it's ok, but I rarely need 3G so there's no problem.

Part of this depends on how your carrier acts. If I turn off 3G it means I can't use data, I can't sync etc. Sync & applications launching and background data is a bigger battery drain...multiples higher than 3G in my guess. EDITAccording to GSM arena, my 2G/3G talk time was way off, but I think their data is old. I'll remove it for now and replace it with "Up to 750 h (2G) / Up to 576 h (3G)"...it's not sooo much the network as what is going on when you might be connected to that network.
edit 2 GSM arena seems to have the most recent info, I thought they were approximating this from their test units.
Just fyi for those unaware.... Bell is a 3G only network, nationwide. You can't disable 3g on Bell and still have data.
Sent from my GT-I9000M using XDA App
I'm also using Juicedeffender and my battery live improved a lot. Now I can run the phone 24-30h without charging.
Now we know the reason why the battery is draining so fast on Galasy S Phones.
The simple reason the AMOLED screen.
If we compare the Droid X with the Galaxy S both with 1500mAh batterys. While the Droid X can reach up to 7:42 hours of battery life the Galaxy s can only 4:44 hours. Its sad because the marketing made us believe that AMOLED is power saving.
Here the full Test from laptopmag.com.
Did you not read this part?
"So should you steer clear of AMOLED phones if you care about endurance? Not necessarily. OLED technology uses the most power when displaying white, which is why Samsung chose a black background for the app menus on its Galaxy S phones. Since our battery test surfs web pages
, most of which have a white background, both the Galaxy devices and the Incredible were at a disadvantage. It really comes down to what you view most often on your phone."
I tested a mkv 720p video playing for 1 hour and it only used 15% battery. From that, the battery should last about 6.5 hrs.
I was reading a test on another site a week or two ago, and it claimed the Galaxy S ran a 720p vid of Avatar on loop for 7.5 hours before refusing to run the video any further as the battery had reached 20, so 4.5 hours seams a little low?

The brightness must have been set to VERY low, non ?
Not quite true that it's just the screen.
I installed a widget to turn off data connections entirely (running on 1G phone and text only) and I get about 4-5 days off a single charge now, and that's with moderate gaming/music/ebook use.
If I want to use the internet/email/whatever I just click the widget, it reconnects in 10 seconds and I am away.
I am also running the LG Optimus launcher as well, which I notice gives me much better battery life than TouchWiz/Launcher Pro/etc (although don't hit the volume button on the homescreen as it force closes)

Well, that's pretty darn good then! I doubt I've seen battery life that good on my phone....
when the phone is set on auto brightness 90% of the time is less than 50% brightness
when is above 50% brightness it is super cool! that's when you see the full effect of the SAMOLED
if you set it to say 60% or 75% brighness you will see the full bloom of the colours.
I'm pretty *****y about my phone's battery life but i have to admit that watching mkv and avi videos on my phone does not drain the battery as i would have expected. 1h30min movie drained around 20% of the battery, brightness in the perfect middle, 3G on and all that. So i think 7h++ playback is definitly doable.
Oddly enough i have the impression that leaving your phone screen on for 1h30min would probably drain close to 20% of the battery (just an impression though, might be totally wrong).
Also, 3G drains a lot of battery. I messed up with my phone and didn't have the APN configured, so no 3G, battery performance exploded, especially if u'r in an area with not so strong signal
i only notice heavy drain on battery when i'm on WiFi or 3G
like browsing the web, downloading stuff
just having WiFi on and 3G on does not consume that much battery, it is only when they are fully active.
all other tasks like watching movie, or doing offline stuff, even playing games does not consume much battery
i can drain the battery with just 4 hours of constant browsing/download stuff
but i can go on the full 24 with 1 battery pack if i do not use 3G/Wifi
on JM1 (or maybe JM2) when i had no 3G and WiFi turnerd off, bascically it would be 2% off every 8h-10h iddle time which sounds really good. However, according to the reported capable iddle time of the phone, it's not that good. People also reported less consumption in iddle.
I don't think i had too many tasks runing in the background (definitly no task killers)

I fully agree with you. I'm surpised my phone uses so little power when watching a movie, coming from winmo I'm shocked I can use this thing for a day (12-18hours) before it dies. Overall I'm quite happy with my set up as everywhere I go I have power cables. Car (check) , Office (check.USB sync) , walking (check, 2000mha solar battery charger) and Home (power adapter). I'm power paranoid due to being with Winmo since the Aero 2130 to X1i.
And yeh, 3g kills things 4hours max when on 3g.
the main thing that seems to drain the battery for me is web surfing and widgets which use the data connection. I now run a minimalist set of home screens with few widgets and have already noticed an increase in performance and battery life. 3g is pretty power hungry, but since vodafones 3g connectivity is so poor, I am often forced to use gprs through the day anyway as I'm plagued with time outs and dropping connections (if anyone from vodafone is reading, I've only been with you 3 months, and already I know I won't be staying with you come the end of my contract!)
Something's gotta be wrong with the test? I mean, look at the Captivate and Vibrant, both do about 4h 45m, but the Epic 4G does 5h 34m? Same screen, same battery, no? Yet ~50 minutes difference? Must be something other than the screen doing something...

I am also running the LG Optimus launcher as well, which I notice gives me much better battery life than TouchWiz/Launcher Pro/etc (although don't hit the volume button on the homescreen as it force closes)

Tachikoma_kun, what widget are you using to shut off 3G?
I came to the Galaxy from a HTC legend and I miss the HTC widget that lets you shut down mobile date completely. When I first had my galaxy on JF3 firmware, I noticed there was an option in the settings to use '2G' only. But since flashing JM8 I can't see this any longer.
Most of the widgets I've seen do some jiggery pokery with the APN configuration to achieve the data/3G shutdown, does the widget you use do the same thing?
Thanks
What's the point of having an android phone if you can't use as mobile internet as you want? I'm on unlimited data plan and my SGS lasts less than half a day on full charge with data on. Its the same thing with my old experia x10i. So I'd assume its the 3g/hsdpa connection. I had a blackberry 9700 as well. Battery life shortens significantly with 3g on.

I know there have been many threads like this but I'm just looking for clarification as this is my first Android phone. At my house I usually get the Rogers H speed with 3/4 bars. When I browse the Internet for just an hour, 15% of the battery has been drained. Is this normal on these speeds?
I plan on leaving an IM client on 24/7 and using GPS/maps daily, so I am a bit worried because this may not last the entire day. I could switch to EDGE when I don't need it but apparently I heard that will disconnect once I start a voice call (and want to keep my IM on always). I checked my battery stats and apparently the cell standby (H) is taking most of the battery.
I am using CyanogenMod 6.1.1 with stock radio from Bell. I'm going to try to see if SetCPU makes a difference. And is there any program that can limit the HSPDA bandwidth so less battery is used? Thanks.

If you are at home or in a Wi-Fi accessible, Turn ON wifi - it uses wayyyyy less battery than the phone radio when it comes to Data....
you could get a extended battery.... Mugen Power has one for 1800 mAH and its the same size as the stock battery so no need of a bigger door.
What is your screen brightness set at? The screen is one of the top battery drain culprits. Try turning off auto-brightness, and turning the brightness down to as low as you find tolerable (depending on personal taste, and the lighting conditions in the places you use the phone the most). I recently just lowered my brightness to 35% (still plenty bright under many conditions) from 45%, and already noticing a significant improvement in batter life. Battery usage of the display dropped from over 70% to 45-50%. I haven't had the brightness set this low long enough to see how it translates to hours/days between charges, but we'll see how it goes . . ..
my battery life is retarded. probably less than yours. i swear i think i lose 1% of battery per minute of web surfing. battery is fine if you do not go on the web and have 2g on all day.
Yeah, it's pretty bad.
But that's the same for most smartphones nowadays I think...
Back to the days of game gear, the battery muncher.
6AA = 5 hours of gameplay.
I just bought some Chinese 1500maH batteries on eBay and I don't know if they're actually 1500maH. If I play with my phone a bit, I get 50% after 8 hours at work. Yikes!

Assuming the screen was on the entire time, 15% drain for an hour of web surfing sounds pretty good to me. The main battery eater while using the phone is the screen, so I doubt messing with your connectivity is going to drastically change your battery consumption in this usage scenario. Changing connectivity to Wifi or EDGE would probably help more during those times when your phone is off but your phone is still connected to the internet.
On a side note, I had terrible idle battery life when I was using CyanogenMod 6.1.1 on my Desire Z. When I was using my phone, battery life seemed normal. But when the phone was on standby, it seemed like my phone was running even when it was supposed to be on standby. I suspect it might have been SetCPU constantly polling in the background. I switched to Virtuous and didn't install SetCPU/didn't do any overclocking and my life improved literally threefold.
