Average Battery Life ? ? ?

What is the average battery life most people are getting from their devices? The reason for asking I beleive that my battery life has reduced drastically, I'm averaging 36hours. I do not use it as a phone, the Wifi & bluetooth is switch off, the unit is used for push email only and I receive about 20 emails per day, very little WEB browsing.
I'm sure my battery life was a lot better when I took delivery of the unit.

Mmmmm.. well I'd consider 36 hours fantastic but then it sounds as if I use mine a lot more for wifi, surfing, phone etc. than you. Perhaps an hour to hour and a half per day and charge once per day but will usually have 40/50% charge left I did see a post from someone saying with reasonably heavy use they could only get 8hrs.
Mike

i use mine mostly for data.. in a 3G area i average about an 9.2% loss per hour.. in a edge area i am averaging about 1.7% loss per hour... these are all estimates since the battery meter only goes by 10's

I am fairly certain that the 3G is eating power. I get a full days work out of it with a lot of phone calls, push email, BT always on, and occasional WiFi usage. I am almost always in 3G, I very rarely lose it and only when at a clients far away.
Later, Lew
BTW, A full days work for me is 9am to 3am.

3G is the problem. Consider switching to 3G via MortScript as described in another thread. Personally, I use the GPRS only setting for normal use. PushMail would consume a lot less energy with GPRS and the speed isn't such an issue for mails in my opinion. Whenever I'm willing to browse the net a bit more, I switch to 3G before doing so (takes ca. 15s via the script) and when done, I go back to the less battery eating and more reliable (for taking phone calls etc.) GSM only mode.
You will definately at least double the runtime of your Hermes. I can do 5 days (phone on at night, little use) by doing so.

Well I can confirm that 3G is the cause, as suggested I've switched to GSM and battery life is a lot better.

3rd charge i managed to get nearly 2 days, had a 4 hr gprs web session last night on minimum brightness and still had 30% battery this morning.
if the battery goes to 0% what happens? data loss or just turns off?

Other than any document/application open at time of shut down you should be ok, not like my old Clie that looses everything that's not screwed down on the storage card. In fact quite often I deliberately remove the battery for a while if I reckon it may help with a lock up (normally due to some rubbish downloaded freebie!!). All saved programmes to Device memory and card remain in tact.
Mike

Using my TYTN for email (check every 30 minutes), newsgroups (check every 30 minutes) and reading both every 2 hours.
Also using the phone for lots of browsing.
And i am also using my phone for making some phonecalls over the day (with and without bluetooth carkit), i get to use my phone for about 16 to 18 hours without need for a recharge.

[OT]
How do you enable auto email send and receive?
Cant find the option anywhere
[/OT]

if you add an email account to your tytn you get the option advanced at the end of the settings. if you click it you will get the option to send/receive at a standard timeperiod.

I use UMTS for email and web browsing continuosly for 2 hours and I'm down to 10% after a full night charge. It's pathetic.

Your device is broke, or your battery is defective. Seriously, if you have a warranty, act on it.

i dont know about that.. everyone seems to be getting around the same battery life... i would bet that if i used mine on umts continously for 2 hours i would be close to the same drain, UMTS sucks alot of battery

that's true and umts sucks a lot of power. i am using mine on umts in tokyo and i can only get 10 to 12 hours. i use it mostly for push email (about 80 emails), an hour of browsing and some phone calls a day. i've ended up purchasing mugen's 3000mah one to get through the day without recharging.

I highly doubt it as I have two 8525 and both of them will be at 10% with 2 hours of continuous use.

Well I'm on my 2nd battery.First one was replaced under warranty as I was getting about 8hrs with very little usage.
I'm on my third charge with the new battery. The first & second charges have given me about 15hrs.
Agent said I should be getting 4hrs talk time and if the second battery is also [email protected] then they will replace the phone. So I'm monitoring until next week.

This may not apply to you (as you probably know it already!), but Windows Mobile does not shut down programmes when you click the x in top right corner. To ensure you are not unknowingly running lots of applications in the background you need to use a programme that really shuts applications down properly - e.g. Magicbutton or HTC X Button. This can save considerably on both battery power and performance.
Mike

Mike, I'm using Magicbutton and make sure all apps are closed all the time. I've read a lot about the UTMS connection on all the time draining battery. I've just downloaded this app: http://www.gb-soft.cz/XDAII/product_gprs_tweak_wm5pe_en.htm
See if this works and extends battery.

WiFi or 3G, which eats more Power?

i use WiFi @ home and work, 3G everywhere else.
my battery was over 50% before bed, woke up with am with 5% left.....
so 45% of my battery life was eaten up in 8 hours with NO use?
any thoughts?

Wifi seems to be a real battery eater on this device (along with GPS). I leave it switched off unless I'm actively using it, and have no problems with battery life (it would last >24 hours if I let it.. I charge overnight though).
As there's no 3G switch on the widget I don't ever switch that off so haven't seen what improvement that would give. Cell Standby is still the largest user of battery, so maybe it would.

Set wifi to sleep when screen turns off.

There's an option for that? Not seen that one..

I didn't know you could do that, however, i already have that option selected....after i found it in the menu.
i guess i'll just have to experiment and see if 3G saves me power over the weekend.

Yeah I am pretty sure that option is the default. It still definitely drains more power with the WiFi enabled than without, sleeping or not. Not sure vs 3g, I disable or enable both as I need them.

I thought Wifi drains very little power ... with my phone on airplane mode and wifi only, the battery lasts over 30 hours with Meebo on, push e-mail on, and e-mail sync every 15 min.

Likewise, I have gps/wifi/2g/screen widgets on my main home page.

This doesn't exactly apply to the OP, but there's a nice app called "Y5 - Battery" in the market that switches off the WiFi radio in areas that you usually don't use WiFi.
Also, you can see what's draining your battery if you go to Settings > About Phone > Battery Use. There's some cool graphs showing where all your battery went since the last charge. Maybe you have a program that's running in the background that's sucking up all your battery.

I have had some battery drain issues since I received my N1 3 days ago. I found that Android 2.1 has a nice battery log (/d/battery_log) which updates every 50 - 55 seconds. In doing some tests to see what was killing my battery I can tell you that it isn't WiFi.
I would say that when in use, 3G draws a bit more than WiFi when actively used, but when WiFi is just idle it seems better than when 3G is connected and not in use.
In case anyone cares...I am still isolating all of the battery drain issues, but one of the biggest I have eliminated by uninstalling seems to be from BeautifulWidgets. I found it hard to believe, but my testing seems pretty clear. I also have a decent draw whenever I'm in the car with Bluetooth sync going. I would have had a hard time confirming this without this battery log file.

Wifi is extremely power efficient on this device.
I use the device on at&t edge and have the wifi turned on all day. the battery drain with pus email i about 4%/hour.
I think the combination of wifi PLUS being on an HSDPA network is killing your battery.

pus email? sounds gross

A quick calculation gives me 2.4% an hour, and that's with sync on, Wifi off, 3G on and using the phone a bit (not so much today). That's consistent with what I see normally - if you never actually used the phone you could push 3 days out of it.. but of course there wouldn't be much point in having it switched on then so it drops to about a day after a bit of driving w/bluetooth on, streaming music, etc.
Of course it's not really productive to look at battery life as 'how long can I make this last' (although knowing I can theoretically push it to 3 days plus is going to be useful on holiday). You work out your average day.. say up at 8am, turn in at midnight, so that's 16 hours actual time that it's needed (assuming you charge overnight like most do) - then fiddle with the settings based on your own use so you hit that comfortably. I'm probably being overconservative right now.. I'm finishing the day with nearly 50% battery left & need to ramp it up a bit Maybe a few more games of Frozen Bubble..

According to the Google spec sheet:
Power and battery
Removable 1400 mAH battery
Charges at 480mA from USB, at 980mA from supplied charger
Talk time Up to 10 hours on 2G
Up to 7 hours on 3G
Standby time Up to 290 hours on 2G
Up to 250 hours on 3G
Internet use Up to 5 hours on 3G
Up to 6.5 hours on Wi-Fi
Video playback Up to 7 hours
Audio playback Up to 20 hours

I'd love to see someone get 12 days of standby!
The specs for mobile phones are always a bit of a fiction.. maybe you could do that if you put it in airplane mode and if you never activated the display at all...
I had a Sony Erricson that claimed 800 hours (over a month!) of Standby. Never got it over 2 days..
Would be interesting to see if anyone has managed 10 hours or even 7 hours of talk time... personally I doubt it.

Some phones in Airplane Mode when not used can do those kind of numbers though. My K800 lasted about 2 weeks in standby when running like above. Though that just proves how pointless such numbers are.

So when using wifi, is 3g auto turned off?

I would assume the data aspect is, but the 3G voice is still active, even with WiFi on.

Terrible battery life

Hi -
I've had my HTC HD2 a few days and although I'm happy with it's features, I'm really frustrated by the poor battery life. The first day I used it the battery was dead within under 12 hours from me starting to use it, and at the start it was fully charged. On this first day I did have email and weather etc on auto check though.
So last night I disabled weather, set email to manual checking and disabled a few other things, but did leave HSDPA and 3G on. There was a slight improvement today but not much, the battery lasted the full 12 hours, but with only 2% remaining.
Both days I don't think my usage was very high. I'd maybe had 10 minutes of phone calls, sent around 10 text messages, listened to 45 minutes of music, checked one or two websites, and played games on the phone for about 15 minutes. Imagine how it would be when I need to make several calls in a day.
I have searched the forum for tips on improving battery life but the main suggestions seem to say that I should disable HSDPA and 3G but one of the main functions of the phone is internet usage and I don't see why I should how to switch to manually putting these settings on and off each time I want to use the internet, just so I can get a longer battery life - the battery should be able to cope with moderate usage!
Does anyone have any further suggestions?
Thank you

Look for an application called 'Bandswitch', it can disconnect idle connections. THis way 3G won't be enabled when you don't need it, should save some battery.
Disable automatic screen brightness and set it to something like 30%.
Disable location services and stuff.
Give the battery some cycles to reach full potential.
But of course, gaming, internetting and listening to music will drain the battery faster. It lasts about 2 days for me with moderate use (some internet, some playing around, etc) which is pretty fair imo.

I'll give that a try. So will it automatically enable it when I start browsing the internet or something?
I already changed the screen brightness and disabled location services though. That didn't seem to make a big difference.
And how much difference does giving the battery some cycles make?
Thanks.

Sorry, but it doesn't work that way
Bandswitch can definitely do 2 things- it can disconnect idle connections, which will reconnect when needed, but this won't switch the transport between 3G and GSM, and has little effect on battery life
Or it can be used to manually change between 3G and GSM, using whichever is selected for its current transport and then autodisconnecting if required. It is the action of switching to GSM which has the most impact on battery life, but there is no way to switch automatically between to 2 as it needs a phone radio off/on to execute the switch.
Poor 3G signal conditions will hammer the battery because the phone will continually hunt for the strongest signal and switch constantly between modes. If your 3G signal is less than 2 bars I'd suggest switching it to GSM until you are in a stronger signal area. Do this by going to Phone/Menu/ then scroll down to Band and from there switch between Auto and GSM. If that makes a difference then you could install a small utility to make the switch easier to access.

seems very odd, mine was fully charged around 11pm last night, have sent around 20 texts, 20 mins calls, had wifi on, done some browsing, abit of sat nav and its on 68% 20 hours later.

I get at least 24 hours with moderate use. Most of the time i get around 30 hours.
I have weather and peep updating automatically + email retrieval at every hour.

When I first got mine it was lasting less than 12 hours too.
Now I'm on ROM 1.61 and have the following settings:
HSDPA disabled
Weather update every 3 hours
Twitter updates ever 1 hours (though it actually only updates when I scroll to the Peep tab)
Facebook auto updates - Off
Stock auto updates - off
Bluetooth and Wifi off unless needed.
Screen brightness - 30%
Haptic feeback, Vibration - off
Push Email - On
I'm getting over 24 hours of life out of a full charge now. I have got the push email set to manual updates only during off-peak hours ie when I'm sleeping. During the night the charge drops around 1% per hour. It was at 47% when I went to sleep last night and was 40% when I woke 7 hours later. This seems to be typical overnight drop for me.
Over my first few days of tinkering and setting up I found the battery drain to be massive. Once you settle down to regular usage it is a lot lot better.
However, just to be careful, I do now have a desk cradle at work so I can charge my phone if I have to.

Prior to my most recent hard-reset I found that if I left the phone in stand-by over night, with it checking for email every 5 minutes, and weather every 15 minutes, the battery would go from 100% to zero in less than nine hours. And that's without using it at all! As an experiment I tried turning off everything that could possibly be using the data connection, and turning off 3G, so nothing was running at all except the phone in 2G mode listening for calls and texts. It still burned 20% of the battery overnight in stand-by.
Since doing a hard reset, if I repeat the second experiment then I find that overnight battery drain is now only 4% - so clearly some piece of software that I had installed prior to the reset was hammering the battery even in stand-by. Quite what it was, I'm not sure yet. (My current prime suspects are the task manager and 1% battery status icons).
If you're having battery drain issues then I suggest doing a hard-reset and then not installing anything remotely controversial for a day or two to see if that sorts out the drain. If it does, then you can start reinstalling things gradually to see what difference each one makes.

Oh, I misunderstood it then... thank you for clearing that up!

It's very interesting, to see the number of people who have battery draining problems. I have the french SFR ROM 1.44 and since the beginning found my battery life satisfying (I didn't expect long life, as my wife has to charge her iPhone every night).
My battery lasts in heavy use 24h (though it can go down to 18h when using internet by 3G/HSPDA for long period like 1h or more) and under "normal" daily use (checking e-mail regularly, 20 min phone calls, sending some SMS, 30 mins internet, 45 mins playing around / listening some music) around 1.5 days.
My settings are:
3G/HSDPA enabled
Weather update every 6 hours
Stock auto updates - every 8 hours
Bluetooth and Wifi off unless needed
Screen brightness - auto
Haptic feeback, Vibration - off
E-mail check: every 2 hours (POP3)

Faulty batteries? I think not....
Whilst I'm a master of google searching, I get worse results using the search facility on this forum than just using intuition.
Anyway, I just wanted to add my comments on battery life after owning a stock 1.43 phone from Vodafone UK. I was getting less than 8 hours life with everything on auto and making just a couple of shortish phone calls and a couple of quick browses. The rest of the time I was in standby and I thought that my phone was one of the worst out there. I had also installed Skype which I had running in the background which sometimes causes the phone not to go into auto-standby even though it would dim normally. I also noticed that I was in a very weak signal area and that my phone was constantly switching between 2G/3G/H which I understand can consume a lot of power. Also, I had stopped using wi-fi to see if that helped.
After reading a million threads, I decided to conduct an experiment last night. Usually if I charge the phone before going to sleep for 8 hours it is down to 70% when I wake up having been left in standby. So last night I disabled everything. Turned off 3G, data connections, My Location, Weather update, Stocks Update, FaceBook login, e-mail updates, Skype, bluetooth, wifi. In fact absolutely everything I could find that could be turned off except the basic 2G phone itself.
Guess what, I wake up 8 hours later... 96%.
16 hours later.... 81% with very light use.
Now I'm going to have to spend many days playing around with different settings to see which apps or functions are gobbling the power. I have a nasty feeling that the weak signal is half the problem
So cheer up! It's not ideal, but this is a brand new, smartfone with bugs - not a Nokia 6110. Higher capacity batteries and ROM updates will come. In the meantime you just have to figure out what is sucking up the juice on your HD2 and disable these functions if you don't need them or when you are not using them.
Good luck and enjoy it! The coolest phone around...

Hello everyone,
like the majority of the owners of HD2, in order to optimise the duration of accumulator charge, I use Band connection control programs , to pass in 3G only when it is necessary. Thus, I have:
- phoneAlarm: to force the 2G mode the night, and also for differ quiet mode if I am in meeting, etc…. In particular, in the case which interests me there, I force the 2G the night and asks to pass to 2G the morning.
- WMlonglife (version for HD2): which normally loads himself to make the effective switch 2G towards 3G or 3G+ if an application program requiring it is launched, and otherwise to remain in 2G. It should be noted that WMlonglife has two applis, one for the configuration, and to make manually changes 2G 3G, WMbandswitch.
- recently, I tested Bandswitch v2.8
I meet the following phenomena, and I would like to know if others also have them, and/or if there are parameters to change so that it goes better.
Point A: Already some question about the icons of the bar of state in top.
There are always two icons side by side. Tell me if I interpret them well.
one with a letter: G= GSM, E= Edge, 3G = 3G, H = 3G+
This letter tellsonly that this kind of network is available, but it does not say that one is actually connected there. Is it well that?
To know in which mode one is actually connected, it is another icon, on its line, with the 1 to 4 bars of reception and a small letter, which should be looked at.
This small letter, it is “H " ==> connected in 3G+, “3G” ==> connected in 3G, “E” ==> connected in Edge
and finally a simple antenna, which I imagine wants to say that one is just connected in 2G, no data connection
Is what all that is correct?
Is there another mean of knowing in real-time the current mode of connexion (and thus mode of conso of the accumulator)?
Point B, use of Phonealarm:
like said in introduction, I force the 2G (mode GSM/GPRS) during the night, and to 6:00 of the morning, I pass it in mode “house” where I put “Car”, by also putting the pin number at it, because it seems that for this transition, one needs the pin number (is it the radio cycle on-off?)
There, the first thing, they is that every morning, when I unlock it I find myself with the screen for input of the pin number, where it is enough to make cancel (because the code already entered via PA and even already connected). Moreover, if one tries to enter a pin number, then he refuses the input.
on the other hand, at this time, the telephone seems to remain in Edge icon “E”, and does not pass in H. On the other hand, so there I reset, then he will connect to H with the boot
Have you also this history of pin number?
For hangs, it is as if WMlonglife did not take the hand to force a 3G mode or 3G+….
this brings me to the point C
Point C: WMbandswitch… after a software reset, my Tel. is connected automatically towards the 3G network (or 3G+) of orange. On the other hand the morning (after to automatic wake up through PA), it remains in E. When I test action manually a passage in 3G with WMbandswitch, it does not change anything. I tested with radio operator chip on Samsung, or Qualcomm (WCDMA). similar behavior….
To check out, I then loaded and installed Bandswitch 2.8, and tried to change into 3G, and there I see appearing the letter H. so, there is a difference with WMlonglife, which would seem to show that WMlonglife does not manage to make the switch towards 3G.
Which radio chip put in WMlonglife?
Have you to it even thing?
Poind D: use of bandswitch 2.8 (on xda): I tested. Hard to know if that is interfaced well with all the remainder. Of your experiment, which one would you advise? It does not have the system of “whitelist” like WMlonglife…
Here is, in synthesis, to summarise my questions
- Has: major significance of the icons
- B: phonealarm and switch of the 3G mode (after a forcing in 2G the night)
- C: WMbandswitch, and configuration/use for HD2
- D: alternative to WMlonglife?
For info, with normal use of browsing, email and phone, I drop of about 50% battery for 24h, that is not so bad, but I 'd like to make sure about the Bandswitch thing...
Thank you in advance for all…

does your wifi drain your battery a lot too?

hi all,
i don't use 3g nor the data network so i don't know what my phone would be like if i used them..
but i seem to be having problems with wifi..
1) after i press the 'wifi icon' on quick settings menu on home screen, it won't connect (preset, with WEP and all).
And ONLY if I go to settings-wireless control does it connect to the appropriate wifi network...
2) I use wifi to go on the internet and browse the web or check e-mails and etc.. after i unplug it, turn on wifi, battery goes down to like 95% after 2~3 mins of internet... and maybe down to like 70~65 after 30 mins?
Is this normal? It's not, right???
Actually, I feel that my wifi's gotten worse since I upgraded from R1FA014 (Rogers x10a) to R2BA020 (Generic UK x10i, no root)....
Anyone know how to fix this???
Oh btw, my bluetooth connection is perfect..
I listen to my music on mediascape using mw600 for hours and my battery would only drop like 1~5%...
let me know if anyone has solutions to this
thanks!!

I use my Wi-Fi for about about 3 hours a day, and the battery def drains faster, but not noticeably so. I mean in that time, I'm browsing and checking emails and stuff, but I don't lose more than like 20% of battery in those 3 hours...

my phone did the weirdest thing today lol
after i watched a show it went from 93 to 68 amdthen i turned off the screen for an hour or so and when i turned it back on to listen to music it was at 71!!!
k i wasnt hallucinating from the heat or anything... so wonder why that happened??
Sent from my X10i using XDA App

That would happen on my old phone a lot...If I played music or video through the loudspeaker, the battery would drop by like 50% in a couple of minutes, but as soon as I turned off the speaker, the battery would jump back up to where it was. On the other hand my old phone was an SE W810 from like 5 years ago, so I'm not sure how relevant that is...

I have to say, since I went from the ...016 to the ...023, although the battery in general is MUCH improved, I thought immediately it was much worse when wifi's on. I just have to remember to either turn off wifi, or plug it in to charge.

yeah.. that's my problem...
right now i have it running 18hrs with 50% battery left ..
but as soon as i do anything with wifi, it just goes down like there's no bottom...
also i hate having to keep going to setting - wifi setting to get it to connect to my wifi..
i click the icon on the quick menu but it doesn't connect to the actual wifi, it will only reconnect after i turn it off and on if i go to the wifi setting ughhhhh

I've noticed its worse at times running wifi.. Right now it's 430pm and wifi has been on since 9am. So 7 1/2 hours with... 46% charge remaining.

As long as I leave mine set to sleep when screen is off I have minimal drain with the 20 update on x10a. I see well over 1d usage regularly. (Almost never see 2d though)
I also leave GPS on fulltime since it seems to make 0 difference unless it's called for by a program.

those with 30-40 hrs on one charge...

How do ya do it?
at most ive gotten bout 20

MINIMAL use (I.e. no browser).

Yes, anyone getting that much battery is running minimal services with < 10% wake time.

I usually get about 14 hours.
I keep my brightness on auto,
surf the web randomly,
I don't turn off auto-sync,
I watch videos, stream Pandora to my car stereo over Bluetooth,
sync 2 email accounts,
send and receive about 20 texts a day,
my facebook and twitter widgets sync once an hour and sometimes I manually sync them in between,
my Tech-Buzz widget syncs once an hour,
Beautiful Widgets syncs once an hour,
I use whatever wallpaper I feel like using on any particular day(some people think black saves power),
On some days I use Navigation and that knocks my usage back by an hour or two if I don't plug it into the car charger while using it.
I refuse to cripple my phones capabilities, or sit it down all day just so I can say I get 30 hours of battery time. If I need more than 12-18 hours, I have 3 spare batteries ready to go.

Disclaimer: DI8 has really reduced my battery life, however I still can get 2 days if I stretch it, and am *always* at around 70% at the end of a normal day. On my last charge before DI8 I was still at around 50% after 36 hours, with normal use.
What I do:
* Wi-fi always on, never sleep
* 4G off unless I know I'm in a 4G area, then on (it stays off anyway if I've got wi-fi)
* GPS off
* DRM and all other non-essential services off
* Screen brightness 1 or 2 ticks above minimum
* Kill only apps that I know are hogs (Google Nav, for example), leave all others alone to do what they want, use ATK as little as possible
* Airplane mode workaround for TWS
I also just don't use a lot of apps that I know are going to potentially prevent the phone from sleeping or otherwise hog up the battery if they happen to start up in the background randomly. I just don't have apps like that. Some people install all sorts of weird crap on their phones that does god knows what, I generally will only install stuff where I know exactly what it does. I also don't run a lot of widgets that check stuff in the background, although I do run Twitter and Facebook.
I am sure I don't use my phone as much as some people here, but it's wrong to assume people who get good battery life just don't use their phones. I make no real attempt at not using my phone; I use it whenever I want. That includes making calls, browsing the web (with one of three browsers), sending text messages or writing emails, using navigation in my car, and playing games.
Of all the things I do with my phone, the only thing I've noticed really super-killing my battery is GPS and navigation. That burns the battery at a rate of about 20% per half hour, which is about as long as I normally use it. But even if I use the GPS for an hour in a day, I can still get about 24 hours out of the battery if I need to.
I'm convinced wi-fi still really helps, and I'm set up so that *most* of the time I have wi-fi. I have wi-fi at home, at work, and actually on most of my route to and from work (my cable company has free wi-fi if you're a cable subscriber). I don't know how good my battery life would be if I didn't have that.

I use to get 20-25 hours easy, now I'm lucky to get maybe 8-10

Same here. Using stock DI18, rooted, mixup kernel with ondemand setcpu and juice defender (it was 5 hours b4 juice dfender installed.

Turned off the DRM service, automatic brightness. That's it. Stock everything else!
I've got GV and talk always on.

I"m a light user; sent 50+ text messages, occasionally check my email, and push email every hour.
At 40% battery life I have 2 days of battery life.
In the background I have
5 essential stock services running
digital clock wdiget
voicemail
email app
switchpro widget
My running time is 5.5% (lol), with display on 2 hours (auto-brightness), 3G on 10 hours, wifi on for the remaining time (Wi-fi policy never sleep), and TWS 0% (airplane mode trick).
Also, if you run wifi make sure you set the sleep policy to never. I'm using the DI18 update and when I turned my phone on I saw the 3G icon in the notification bar when there should be the wifi icon. Setting the wifi sleep policy to never will stop the phone from using 3G when the screen is off. NOT fixed in the DI18 update.
Attached my wallpaper lol

what exactly does wifi never sleep do to save battery ? also I seen it mentioned on a dif site, set it up that way and when the phone went off it appeared the wifi did also .. idk need a lil insight on that whole setting

Normally, wi-fi uses a lot less battery life than 3G, so sometimes you want to use wi-fi and not 3G.
You set wi-fi sleep policy to "never," so that when you have wi-fi turned on and the phone goes to sleep, it won't turn off the wi-fi and turn on 3G. So the phone only uses wi-fi and "never" switches to 3G.
You have to manually change this in the advanced settings.

I don't know if it's something I downloaded which is eating my battery. I guess I'll try to do a hard reset, if that doesn't solve it, time to root

I can't get more than 8 hours on this..any suggestions to increase it?

I never get to 10 hours but I use my phone constantly. I on average use two batteries a day. I believe I should get the most out of my phone, I am paying the monthly fee, why restrict myself cause my phone will have a dead battery, I always carry a spare.

Same here, I got 2 batteries off of ebay so I use the hell out of my phone. Brightness is on max to show off that screen, stereo bluetooth and pandora,4g is always on, live wallpapers and browse internet and play games a lot (angry birds mostly) . Battery lasts me 7 to 8 hrs which is amazing based on how much I use it. If u are doing normal use and getting 8 hrs then something is wrong, ur maybe not in 4g and 4g is ona nd ur wasting batt looking for signal oor something else. Maybe u have a service running in the background. I removed media hub and drm bc I heard they run a lot, but I never did a proper b4 and after comparison so not sure if it actually does help. I'm using noobs andromeda rom and d18 update.

Id be SO happy if I could even get 6 hours off one charge.
I'm lucky to get more than 3hours these days from 100 to 15%. :\
I did have a lot of widgets, but I removed a majority of them. I NEVER have wifi, 4G, GPS or sync on. My brightness is always set to 0%.
I guess I just use the phone too much! I don't mind because I usually am able to get near a wall outlet to charge my phone in the middle of the day.
But I'm worried about tomorrow, where I'm leaving at 8am and not getting back till 6pm with NO ACCESS to any wall outlets. I'm pretty sure I'm not gonna make it. Lol.

I'm convinced that with regular use you are gonna get 8-10 hrs on a full charge. Hell by 8 hrs you are going need to start charging unless you want to wait until the phone dies so you can claim x amount of hours.
There is no point in turning off everything on your phone and barely using it to say it lasts 20 hrs. Get a charger for work, home and your car. It is what it is.
I wake up at 6am, charge by 2 pm when battery is around 30%.

the problem with this phone bottom line is that 3g is eating the battery life. I set wifi to always on and I'm always on wifi in the house. I can get 12-14 hours sitting in my house. whoopie doo. Thats not hte point of the phone, the point of the phone is to have mobile service, not wifi service. anyone that is getting 30 hours out of the phone is using wifi. So thats not even a fair comparison. I love the phone, but this is just stupid, I shouldn't have to carry a spare battery with me if I go to the daytona 500 from 9am to 9pm.

Yeah 3G does eat more battery life than wi-fi but that doesn't mean you can't have great battery life with 3G on all the time. I can get 1-2 days with 3G on and with light use, but that's in part because I get a good 3G signal.
I probably emphasized too much on wi-fi but the point I'm trying to make is try to avoid using a weak connection. Generally, I use wi-fi/3g/4G in my home but inside most buildings they'll most likely have weak 3G and 4G connections, so I use the wi-fi network inside the building.
You said you could get 12-14 hours with wi-fi and not touching the phone? I'm not trying to be rude but that seems really low. If mines idle on wi-fi in my home it lasts days. With 14 hours idling, that means the battery life drops 7% every hour. Idling on wi-fi I think it should only drop 1-3% per hour.
Mind if you go to settings -> applications -> running services and post what you have?

i get twenty four hours on average a full day so to speak wake up it says fully charged i take it off check twitter and facebook leave the house and dont touch it until i am at school bored in class lol and then it says 95 after a full day of class it usually says 66 thats after 9 hours i go home play with it download apps etc make several calls and i text alot all day by the way and then i go to work and it says 50 or about 48 usually i use it all night off and on til i get home at seven my wife kills the battery and puts it on the charger while i sleep usually about 9
