Battery - up 'n running for

...4 hours of heavy usage (wifi connection and 3g on but idle)
Mid to periodical usage could reach 24h.
6th day of usage....
i think this is mediocre for me. please report your battery performance to compare.
Any tips to improve this?

I can get around 8-10 hours with heavy usage... constant music, etc.. and about 2-3 days with light-medium usage.

Hmm so i guess there is a problem with my device.
Great!, and how am i supposed to explain this to the service?

I get about 12 to 15 hours of heavy usage via web, text, and email. If i watch video it's less but I am pretty happy with the battery thus far.

I can only get around 7 hours of use.
I have a problem that if i even dont use it, the battery still drain. I got it full charged and theb unplug it. About 8 hours later, it went down to 50%.
Is there any problem with my device?

same here. i don't know how you guys are getting so much better battery life. i can barely last a day and i don't use it all that much. maybe 2-3 hrs of surfing the web over wifi (not even 3g). i even used setcpu to underclock to 200Mhz when screen is off.

Maybe it has something to do with the very first charge.
When i unboxed the battery was fully charged so i drained it and had it charged for 8 hours. maybe it needed to be charged prior first usage.

Is that 12-15 hours with the screen on? Because that's much more than I'm seeing.
I've done a few measurements just to get an idea of the battery life. They are just extrapolations based on a few hours of runtime for each so they are by no means exact, but my impression is that they give a decent view of real values nonetheless. The battery percentage indicator does not seem to be terribly non-linear.
Video playing (SD quality) with full brightness: 5.5 hours
Video playing (SD quality) with lowest brightness: 9.5 hours
Idle at homescreen with full brightness: 6 hours
Idle at homescreen with half brightness: 9 hours
Idle at homescreen with lowest brightness: 12 hours
Music playing in headphones (screen off): 90 hours
Can't believe how lazy reviewers seem to be, I haven't read a single one where they have properly measured battery life for things like playing movies or reading an ebook. It's all just subjective feelings (which are obviously very unreliable).
All in all I am pretty pleased with the battery life (but I've just had it for a few days). I especially like the fact that it's basically a normal Android phone just with a giant screen and battery. This obviously means that standby and music playing times are going to be excellent.
Edit: Those of you who think you're seeing bad battery life, what does the battery use thingy in settings say? Or is that not a good tool?

I read a post somewhere where the OP was getting horrible battery life and found out that the Gallery app was draining the battery.
The OP in that thread said even exiting the app did not kill it, and it kept draining the battery.
Perhaps you can look into this more. I never use the gallery app so maybe why this is why i get decent battery life?
Edit to add:
Here is the thread
http://forum.xda-developers.com/showthread.php?t=826472&highlight=gallery

If it's this post you're referring to it's by me . The Gallery application shows up under battery use though, so I'm pretty sure that's not it.
Are you sure it's really as much as 12-15 hours with the screen always on? If it were 9-10 hours with brightness at half it would around what I'm seeing I guess, but 12-15 is quite a lot more. Not that I'm disappointed, but if better is possible better is what I want

No not 12-15 hours with the screen always on.... I get 12-15 total... Screen on for usage, off for a while, back on to email and SMS ect...

Ah ok, then there's no discrepancy .

I got 10 hours from full to complete off. I was using it to watch streaming movies on 3g
for a couple of hours and then watch a movie off of the sd card and an episode of supernatural.
After that its just web and ebook reading. Its pretty good. Almost the same as my ipad.

I got a total of around 14 hrs plus with wifi and edge on, screen brightness at 20%, around 7 hrs of standby while i was asleep at night, with 4 hrs of heavy surfing, youtube etc. . . No calls though, only some sms and always on IM with nimbuzz logged in.
What i am seeing is with heavy usage i.e. Multiple apps running, wifi and edge on, i get anywhere between 5-7 hrs of battery life which i think is fair enough for a device this size which am constantly fiddling with.

Can someone please post,
Using the supplied mains charger, how long does it take to fully re-charge a drained Galaxy Tab?
As it is a large battery what sort of charging times to expect?

I've not used mine for that long, but the Battery Left app(which I found to be quite accurate on my N1) shows that for MY usage, I'll get about 25hrs.
I've got the auto dim turned off, and brightness at max. I mainly use mine for checking emails, txting, and a few games.
Nothing heavy.
I'd recomend the Battery Left app to you guys looking to find out your battery life. You DO have to "train" it though, which requires a 100%-0% run for you.

Guys,
does.anyone know, do we need to cycle the battery to give it the best performance?
Example, charge up the unit, then drain it completely and recharge it again? Like in the old days.
mine hasnt gone down much. I have it unplugged at 6am and at 4pm i still have about 75-80% batt left.
This is with about approx. 2 hrs of talk and 30mins of data usage and voice calls paired to my BT headset. My screen brightness is set to 40%

I once got up to 20 hours of moderate usage. But with heavy usage I get about 12 hours or more. I lose about 7% when watching an episode using flash....kinda sucks but I watch a lot of anime online. But I use this as my main phone too. Its replaced my nexus completely. though it was nice with my nexus cuz I could swap batteries. This is how I condition my battery. I let it get to about 2-5% then I recharge it. I don't let it get to zero cuz I heard you can damage the cell. sometimes I charge it to about 20% then I unplug it and drain it to 5% then back up to full. I just kinda switch it up. At first I was getting horrible battery life but ever since I started conditioning it this way I get great results.

Battery Tips?

I just want to know what I can do to improve my battery on CM7 nightly 32. I'm at 21 hours now and almost dead. Yet I see people get stuff like 2 days and 10 hours... I have tasker and the only profile I have is when the screen goes off it turns mobile data off (not sure If it works so I also use apndroid). I NEVER use wifi, bluetooth, or high brightness. I do however have gps on so in case I lose my phone is lost or stolen I can track it. So there's no way I'm disabling that. I have tried juice defender but figured since it can't effectively disable data for 2.3.3 I saw no point in the app. Any tips?

21 hours on moderate use is great battery life. 12 hours is usually the measuring stick for smartphones, less is bad, greater is good.
Don't know who you saw getting two days plus, but they are either not touching their phone or have an extended battery.
Sent from my T-Mobile G2

Best way to extend battery life is to get an extended or high capacity battery. I just got the Mugen Power pack, not the chunky one, and im in the process of breaking it in.
On my stock battery i was getting about 17hrs of moderate use. Almost no talk but alot of texting, engadget and youtube mostly on wifi with gps always on. That might give you an idea, plus, there are countless battery related threads on here.
Will post back in afew days after my Mugen has cycled afew times.

I have 4 stock replacement batterys and never plug my phone in to the charger. When my phone is at about 5% i just take one out and pop the next one in and charge them in the wall... I know its not the answer you want but I never have a problem with battery life lol

I would agree that 21 hours is great battery life on this phone. I can get a week of battery life on my phone if I put it in airplane mode and stick it in my desk drawer =P
Not sure how big of an impact the tasker profile has. Unless your screen is off for long periods of time I would think that it might harm the battery life because every time you touch the device, it has to 'search' and connect to the tower again.
You can try running the phone at the stock CPU speed to see if that has an improvement on your battery life. I currently run the same 1017/245 as you with a screen off profile set at 245/245.
For me, as long as I can make it through a day's use, the battery life is fine. With moderate use I can go about 15-18 hours and heavy use I'm at around 12. The car charger in those cases is a life saver.
Bottom line is, battery life really depends on your usage habits. Those people getting days out of their phones likely aren't using them very much...

well i have setcpu set at 806 max and 245 min. screen off is at 245/245 and on powersave governor. other then that its on ondemand. i also have profile set to reduce the CPU based on battery. I have it set to <101% its at 806/245 , <41% its at 768/245 and less then 25 is 368/245. i realize that these are low speed but i hardly ever get lag and i use it for everything, music, video, youtube, internet, twitter, facebook, xda , and a here and there gmail. i guess if im getting exceptional battery life... anyone want some tips?

I find the more variation I put into profiles on setcpu, the worse my battery life gets. Theory - it is constantly watching and making changes based on your CPU needs and battery. So I have mine set to 1113-1113 performance, 245-245 powersave screen off, 245-245 powersave 45degrees+ and for your mobile data, try just having a widget to turn it on and off as you need it. You probably don't need it on everytime you turn on your screen do you?

The apndroid widget eventually gets out of sync with on/off with the data... I think its gingerbread. Most apps can't effectively turn the radio off. I hope they make one soon!

I find the stock battery to be not that great. I bought the Chichi batteries way back in October (when they were still considered cheap) and theyve been great. I havent really done any new tests since October, but back then (before I had a data plan) I was getting atleast a day and more (from 100% to dead) with moderate usage.
I'd look for a high capacity battery, though they seem to be expensive now.

Ill post a battery success story...sounds nerdy lol. And i live at my own home with my own family lol.
My mothers g2 is rooted and running cm7 nightly 29 or 30, I installed it last week. I asked her today for the first time how the battery was after a week. She is using an aftermarket 1800mah battery, wifi only at home, she was almost at 32 hours and had 39% battery left!!!!
Not sure of all settings but i put it on 1113mhz, on demand with min 368, autobacklight, wifi only at home, bluetooth is always connected and on. Talk is about 70% of her usage overall. 4 gmail accounts. I did not install set cpu at all. I even stopped it on my phone because it didnt help me one bit.
Not too shabby. I was at 57% with some texting but a lot of gps usage for latitude and wifi always on even when not at home.
sent from the rooty tooty fresh and fruity cm7 nighly powered G2

here is what i get out of a day (battery consumption for specific tasks are mentioned in percentages measured using juiceplotter)
wifi on constantly
display set to 24% brightness
background sync enabled (google, weather 6hrs, whatsapp and facebook once a day)
45 min video (rockplayer no h/w decoding) 15%
1 hr browsing+chat 15%
30 min calls 6%
20 min music+chat 5%
20 min general usage 5%
1 hr flash streaming 15%
24 hrs standby 24% (@ 1% for every hr of standby)
15% battery remaining after 24 hrs i.e. low battery warning.
i disabled the use wireless network option under locations and always on mobile data
and get much better battery life, also i use wifi constantly when available (which is 90% of the time), it is much better for battery life than using 3g or gprs/edge.
pretty amazing battery life IMO i am very happy.

So i have cycled my Mugen 1800mA battery acouple times. on average, i'm able to get about 27hrs of heavy use. Here are some settings as a baseline:
Always on Data
Wifi always on
Auto brightness
1GHz clock speed
massive amounts of text use
massive amounts of screen on time
will report back in afew days time after some more cycles.

what about battery of Iconia A500

hi all
I'll buy Iconia A500
But I heard that the battery life 4-5 hr only
is it really ?
Also learned that it can run USB 3G Modem by patch.. Search for a video on YouTube about this but did not found.. is there video ?? and how much battery life when using 3G Modem..
mmmmmmmmmm
if battery bad
can i change batter?? any tablet battery can be used??
I apologize for the many qestions and my bad language

I don't know about the rest, but my battery lasts about 9 hours of reading e-books and comics, some games (a lot of gaming = about 6 hours). I don't do much video watching, but someone who does can answer that for you..

To answer the obvious, battery life depends on the kind of use you put it to.
Reading eBooks, playing games can be quite draining on the battery. Maybe up to about 7-9 hours. If you light browsing, wifi always on to get mail and do light reading, you could potentially get up to about 50 hours or more of battery life.
Cheers!

thanks for answer
what about USB 3G Modem ??

Best I can tell you need either one of the custom ROMs or a custom kernel file for the 3g USB modems; see the A500 Developer forum for more details. Battery life shouldn't be horribly affected while using an external modem, although you will lose some battery life.
My Iconia tends to last the entire day on a single charge; I leave the WiFi on full time for the most part, and get a couple of hours of off-and-on web, email and e-Reading during the day with a good solid 3-5 hours use at night. I do suggest charging once a day just to keep from running out unexpectedly, but I have had it last two days of light use before when I missed the charger being unplugged...

i cant confirm battery life with a 3g modem attached but without one my tablet usually last about 2 days, thats with wifi always on but with airplane mode on(helps with the cell standby bug for me), 5 hours of display time mostly web browsing, downloading and email usage.

OC to 1.4Ghz,
Full charge before sleep
Wake up at 96% (drop very slow during idle)
Travel 30 mins to office with light web browsing (90%)
Leave office at 85%
Play dungeon defender (3D game) during 30 mins travel back home (7X%)
[web browsing + dungeon defender] (total 3 hrs), the battery still get around 50%
So, now, the battery has been off charger for 20 hrs, and the battery is around 50%.
I say 'great' for the battery life.

I believe s-off has something to do with the 'radio' in the tablet, which sends and receives signals. The cell standby bug is that when Acer made the software for the tablet, they never disabled the 3g module that continuously looks for a 3g signal. This is a big battery drain and can be disabled by using an app that will do it for you, if your device is rooted.
I have a question: I have been thinking about getting the a100 which is supposed to come out 'early august.' It looks like the only differences will be the screen size, half the RAM, and maybe the size of the battery(s) they put in the tablet.
Can anyone give me information on how their battery life is while listening to music? Is it a massive drain, or is it nice on the system and not cause much issue?
Thanks for the information!

I do wish people wouldn't keep repeating this blatant misinformation.
How can there be a battery drain when the cell hardware doesn't even exist? Sure, the app is polling, but there's no hardware there so the ONLY battery drain is the minor amount caused by the app running. What you're seeing in the battery status is merely a erroneous data caused by the app failing to connect to the non-existent cell hardware.
If the battery usage it indicates were true, your battery would be flat in about 6-8 hours. Mine is now on its 3rd day without charging and is STILL above 40%

Android OS at 52% and battery lasting 5 hours help..

I had problems with my battery, but since I rooted the phone I think that it is getting worse. I am not sure if it is the rooting, but now I am getting Android OS at 52% and the battery barely makes 5 hours. I am a using the phone, but it should last at least 10 hours. I did root the phone in order to delete batterystats.bin but this did not help at all. I used Battery Calibrator, also deleted the batterystats.bin from the Android Terminal followed the procedures of charging the phone to 100% waited until it says full calibrated the battery or delete the batterystats.bin discharge the battery until the phone dies and charged it to 100% again....but still the same thing. I guess the Android OS is killing it. Any suggestions will be greatly appreciated. Thank to all of you in advance!

52% is high, but that also depends on what other tasks you are doing at the same time.
You should have 5 hours of Screen On time if not more, thats what you need to check, not some hours.
Regards.

5 Hours screen on time? I'd love to get that lol. 3 Hours 50 Minutes is about the best i've got, but then that is while battering the net and the camera.
Get around 1 to 2 days battery life though although I am a light-medium user.

Install the free version of Wachdog , and see if it can identify what apps or processes are eating up your battery.
https://market.android.com/details?id=com.zomut.watchdoglite&feature=search_result

Look here:
http://forum.xda-developers.com/showthread.php?t=1230140

So to make it clear. My battery lasts about 5 hours. I do not think this is screen time. This is the total time of the battery. I have at battery use
Android OS 52%
Display 13%
Android System 10%
Email 9%
Cell Standby 4%
Voice Calls 4%
Phone Idle 3%
Maps 2%
I think before the rooting I had Android at around 12-13% and the highest was the display. I keep the display close to maximum brightness, but it counts only for 13% at the moment and it was around 40% before rooting. Do you think resetting the phone could solve the problem?

That stat you have given is after how many hours of usage?
Besides, what kernel did you use for rooting?
Install 'Better Battery Stats' and see whats going on in background.
And do turn off Wifi, GPS, 3G, Packet Data, Auto sync, Background Data, any running widgets when you don't need them. And also check if you have push-pull Exchange.

I have Belkin N750 DB, and It was OK before. When I turn off wifi and restart the phone Android OS is still at 52%. Also I have no problem with my Galaxy Tab 10.1 on the same router. But thank you very much for the suggestion.

If you have wifi and bluetooth on constantly also 3g , you are really taxing the battery 5-6 hours is about right.

I had simillar problems. High os usage and short battery life.
Used better battery stats overnight with everything data related turned off and fully charged phone. turned out that my facebook app was keeping the phone awake in standby and killing the battery. Lost 55% in 6 hours. Removed fb app and battery life is mutch better. Went from 8 hours with about 1 and half hours screen time to 14 to 16 hours with 3 to 4 hours of screen time on one charge. Os usage is now between 20 and 35%. Use to be at 50 to 60%.
This is with stock kernel with wifi and 3g allways on with some autosync and push mail allways on.

You just need to tap on Display under battery usage graph in settings.
Also FB doesn't stay awake in background if you Exit it. So think before you remove it, if it's needed to be removed or not.

Since the phone was charged it is 1H 32M 16S. I am at 88% of the battery and 9m 3s on Display time. I do not have the bluetooth on, the gps is off Facebook app is removed. The only think that I gained is instead of Android OS at 52% I have it now at 48%
I rooted with KG5. If I try to root with KG6 do you think this might solve the problem? My stock was KG5 on a phone from Expansys USA Polish model.

Battery - Your opinions

Hi guys,
Since I don't have much notion about the battery life I would like your opinion please. I think now with 4.0.4 the battery is great.
Today I used a little wifi, a little 3G, around 50 texts, 3 calls (short ones) and played a game for about 5/10m.
Let me know what you think!

With rooted 4.0.4 with cwm I get 36.5 hrs of battery life compared to gb witch was 20-21 hrs.

If i have a intensive use, the phone only remains for 20h but with gaming, net and bluetooth... With normal usage, can last for almost 2 days. good battery usage

Mine is the same; crappy. Lucky if I can make it through the day without a charge.

But do you think this is good stats?

My Arc S is rooted, with stock 4.0.4 and the battery lasts for about 36 hours. With GB it could reach ~50 hours.

after ICS Update my battery life dropped barely get thru a full day... Few short calls, about 7 SMS', facebook for 10 mins total and google and battery is dead

I think that better battery was on gb.

Crappy, especially if you use 3G + Browser.
Browser eats too much power.

true! I only can get 3 hours+ on 3G browsing.

If I leave my phone alone without fiddling it with, the drain is minimal. But I tend to message a lot on WhatsApp, use both Dolphin Browser (on wifi) and Opera Mini (on 3G) and then the battery comes crashing down.
I'm a heavy user so never been able to comment on battery life BUT I do feel the overall battery life on ICS is better than it was on GB.

After my arc upgrade to ICS 4.0.4
I think battery life is slightly tougher too..
Wifi always on (80% on)
Juice defender on (disable data via 3G)
Running on 3G (wcdma/gsm)
Screen used 4h
Battery life reach 1 d 1 h
Its awesome for me

On ICS the battery is poorer than inGB
Typed down from the sky with sexy LT15i

People with battery lasting less than 22hr you must be excess using some how. I have and lt15i- rogers, an lt15i - telus and a arc s - no carrier and all of these are rooted 4.0.4 and they all reach 20 hr or more. The lt15i- rogers battery for yesterday went like this:

ICS should give more battery life than GB theoretically coz many changes were made to optimize battery life..so if you are getting less battery then some bloatware or some app is causing battery drain..screen eats battery like hell..but still my screen brightness is around 80% coz screen is sooo beautiful but still i get around 2.5 days of battery easily

You keep your screen at 80%? I keep it at 30% and it's still bright. I actually find that to be optimal.

before my screen brightness was also 30-40%..but later thought wat will i do by saving battery when i m always nearer to plug point..so recent started keeping 80%

I think 30% brightness is enough for me, and my battery still always reach for one full day use. (from unplug charger 9am - 11pm plugin charge)
Screen always 3h ++
Signal wcdma/gsm
Wifi always on
Maybe my next post will included pic, coz now i cant insert pic (my post only 5)

But not on my usage scenario. 3G and browser.
My usage pattern did not change, reading news, weather, browsing tech sites etc. But ICS browser really eats much power compared to gingerbread. The phone noticeably heats up faster, too.
I already removed the bloatwares, test it with stock kernel first, minimal app installs.
