How long does YOUR battery last...?!

Now, I know that it depends on what programs are running, like... whether you have any minimized or in the background, but on an average 1500 mAh/3.7V battery... what is the amount of use time that one can expect...?
Let's start a thread on this subject... listing the type of battery, approximate age of same, the names of the files/programs you run & use in a given day, and the amount of hours of overall use you get before you have to recharge or switch it over to a new/fresh battery. This way, we'll all have a better idea as to what programs really drain the phones, such as when you leave the WiFi and/or Bluetooth "on" all the time - waiting to be used (a sure guarantee to have a dead battery in a matter of hours).
We can subtitle this one under "The Cost of Staying Connected" (not including air-time charges or monthly fees).

i think my battery life is terrible... but its understandable. usually i run wifi and phone all day long.. the only reason i run wifi on all the time is because i have a feeling everytime i don't... somehow i get charged for using evdo (from bell in canada)... but i dont?? its really weird because i used to always get these random charges.. but ever since i kept my wifi on all day everything is all good. i have the original battery that came with my ppc 6700.. and i use the phone around 40-70 minutes of talk time. no real apps running but a few games of solitaire here and there. but if i were to talk non stop it only seems to last like 1hr
my battery life is like 10 hours and i always have to charge it when i get home from work or school or ill be doomed the next day

Since upgrading to WM6 (thanks helmi), my battery life has found NEW life. I used to have to charge it everyday: no wifi, 50% brightness, screen off in < 1min, etc. Since upgrading, I can run it at 100% brightness, screen off in 2min, and I don't have to charge it every day.
This is with the factory battery, and an eBay replacement sometimes used.

always running: freestyl (flashlite), sms threader, mbutton
phone is usually locked with s2u2
most use it usually gets is me checking the time
update rom from verizon, .net 3.5
ever since i updated the rom, it seems like i only get <24 hours per full charge (battery purchased less than a month ago)

w/o wifi or bt i get about 3 days however it depends on what version of windows are you running have you guys updated to the new 6.1 or 6.5 biulds?

My battery life its very short but, i use my apache with core play at my car with my kids plus the wifi, and blue with hand free, soo i've to conected every day, and i'm use 2batterys

original battery... i got 3 days on standby.. and 2 days in normal call usage...
but
with wifi my battery gets drained to the bone in 40 minutes LOL
thats all =D

About twenty minutes. I know I need a new battery >_>
... that and that I'm surprised I've got over 240 hours clocked in the lifetime call timer.

Using a 2600mAh 3.7v Battery
I had my extended battery for about 2 months now.....
TCPMP:Battery life is close to 5 hours on the lowest brightness level using headphones & on speaker mode I get about 3 1/2 hours.
Making Calls: I sometimes spend about 2 to 3 hours on the phone & that leaves the battery to about 70% or 60%.
Wifi: I don't use it for a very long time, but when I do it could be about 1 hour and that can leave my battery to about 80% to 70% when done.
Videogames: I use mainly the Morpheus(emu) usually about 20 to 30 mins and only seems to leave it close to 90%..
With random use I normally have to charge the battery every 2 or 3 days... I play with the phone quite a bit tho! Mostly text messaging (turning it on & off about 20 to 30 times daily).
With my 2 normal batteries? I think they need to be discarded soon lol!!!!!!! Wifi will deplete them(each) in about 4 or 5 mins tops!!! TCPMP about 10mins(screen on at its lowest with speaker) & 15 mins max(with headphones & screen at its lowest brightness)... Phone Calls? about 20mins tops(with the screen turned off)!!!!
So.... I strongly recommend the extended battery on Ebay for about $22(shipping included) so that you can enjoy the phone alot more!!!
I try not to keep the phone on the charger until the battery has depleted to about 20% when the warning comes on and fully charge it always!

Abysmal Battery Life?

Hello,
I understand people complain about the battery and search around here for issues regarding it and find many.
But mine seems to be shockingly bad. I have HSDPA on, weather, stock updates every 4 hours, twitter every hour, and tend to use Palringo on constantly (maybe this is the issue?). With about 2 hours of FM Radio, maybe an hour of music... the phones battery only lasts for about 7 hours which is not great.
Is this about right for the phone? Or is this shockingly bad compared to others? Its hard to quantify from searching about what the "par" for this device really is.

This is not much, but not shockingly bad. Have you enabled the power saving mode in Palringo?
(I actually don't know what it does, but there is one )

Palringo and beejive on my HD2 sucked the battery like a over active dyson vacuum cleaner!
Nimbuzz seems to be better for battery life but not perfect.
On sunday I managed to kill my battery <5 hours so 7 hours is better than what I get sometimes

another post. geeee
i had asus p750 which battery last for a day or so with minimal usage
i had se w910i while only on 2-3h of phone calls i had to charge the battery every 36 hours
i had an iphone 3g which i had to charge every 2 days with very gentle using
a friend of mine is using htc mda something with the hardware keyboard and has to charge the phone every day
anyway - i can charge my hd2 every night if necessary - it is a very good phone anyway

That might explain it then
I can appreciate that hammering the data connection or whatever Palringo does will not do the battery much good sadly. anyone else use Palringo and get better battery life?
I have the power / data saving mode enabled, although as you said, quite what that does I dont know
Thanks for the replies....

My HD2 is significantly better than my T-Mobile G1 I had previously - that phone definitely needed charging every day and I hardly used it really. I get a good 2-3 days with light usage from the HD2.

I had the same poor batter life before when I first had it. But last couple of days I finally realized that it's the 3G data connection sucking the battery life like nothing. No I only enable data connection whenever there's no wifi for me. But I keep the WiFi on constantly with push mail. The battery life lasts almost about 2 days. So I'm more than satisfied with it now. The iphone/ipod touch needs to be charged every single day mind you. So my advice is to avoid data connection whenever possible since wifi doesn't really suck much battery juice it seems.

Hi
In my case using palringo the battery drain is 8 % per hour. Without palringo running is 4% so double battery life. I ve repeated the test many times with same result...

Thanks mate, this is exactly what I was hoping to get confirmed. I'm seeing something similar, I guess short of not using Palringo there isnt much to do. I do have a charger on my desk at work, so I'll just plug it in.
Interesting I did see that with it plugged in charging and turned on (set to Disk Drive mode) at work the charge barely increased 1% over a period of an hour or so. (I did check that the option to not charge when connected was not ticked). So it wasnt that, just caught me by surprise as it seems it barely charged.

Battery Drain HD2?

Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.

+1
-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days

we really need extended battery ,hd1 battery was much more better.

Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87

I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.

I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.

try setting Network Selection to Manual

Same here with and without stock ROM.

yeah.. the phone is a battery sucker.... another cons of HD2....

This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.

I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?

maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse

I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy

Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.

Battery Life??

Hi Guys! and Gals..
Wondering hows your battery life?? Can you make it through a day Ok? I have a touch pro on Sprint and battery life stinks in the worse way.

Last time I checked, it went 13hrs until 31%.
I usually use it for around 90minutes continously reading or web browsing during my commute. There is also 4-5hrs (or more daily) during which I only get 1-2bars of receptions, so it drains battery faster. There was probably also a 30-40minute phone call using bluetooth.

I can go an 10-12 hour day with light use:
45 mins of phone and text (no bluetooth)
20 mins phone (bluetooth)
30 mins misc.
30 mins games.
20 texts.
Data on about 8 hours without Wifi and 4 on (N enabled)
1 hour browsing, emails etc.
30 mins with Microsoft Reader.
Probably a little more.
Also syncing a lot with calendars.
Not bad, but I feel like it could be better.

t-mobile usa.
I have 75% by end of the day

Adjust your PEAK TIMES for ActiveSync, that way your device isn't consistently trying to allocate resources to collect data such as emails.
Screen brightness, system volume, hibernating times, etc.
ALL OF THOSE are key factors in how quickly your battery will be drained. Anything involving the on-screen display is what will quickly deplete available battery life on a single charge. That may seem very "cliche" to say, but the fact is, this device has a 4.3-inch screen, so it's a power hog.

For today, it's been 17.5hrs since I unplugged and the phone has been mostly sitting except for a few occasional brief checks of the phone, 30minute email syncs, and a 15 minute phone call. It's at 40% battery after the 17.5hrs.
It did drop around 20% in the first 6hrs since the phone was in an area of horrible 0-1 bar reception. The rest of the time has been 2-3 bar reception.

17.5 hours @ 40%... are you serious?
My TMOUS HD2 has never gone more than 8 hours on a full battery charge. This is with "normal" usage. Regular email checks, activesync with direct push.
Comming from the Blackberry Bold II with 13-15 hours of battery under normal usage patters, the HD2 is VERY WEAK!!!.
I'm contemplating sacraficing the sleak look of the phone for the extended battery.
Anyone have the ex battery? How's your battery life?

If you need direct push in your life, then I suggest changing 3G to EDGE network.
Difference is quite noticeable.

It sucks,and if you want better battery life don't use it.I returned mine after 48hrs.
All the advice is great,but....
-If I have go from 3G to EDGE.
-Lower the brightness almost to the minimum.
-Set activesync up.....What is the point of having so much technology? if I can not use because the phone dies.
I need real time email and 3G to work,plus all the stupid menus that windows mobile still has made me change my mind.Microsoft has been in the market for a bunch of years and winmo still sucks.
Do not get to impressed with the HD and the movies,cause the thing dies in no time.
Don't buy it and stick with android.

I end the day with about 60% battery life left with mild-medium usage. A few phone calls, some maps/gps, active sync every 4 hours, facebook every 2 hours, weather every 3 hours.
VERY happy with battery life on this phone

i went all day yesterday (my first day with it) so i used it alot, took it of the charger, at 7:30am, and plugged it in last night at 10:00 and it was at 39%. that was BEFORE i turned off 3g(i dont get 3g in my area) so this hd2 blows the iphone battery out of the water....IMHO

my last device was blackberry 8900.
that thing lasted 3 days with moderate use. compared to that, 15 hour limit does suck, and there are times I don't want to use the phone to conserve the battery, which makes rage, but oh well. now I always carry an extra battery in my pocket, so that's a bit better. but that doesn't make it okay.

with the 3g off, wifi off, auto back light,running the energy rom apr 9. unplug on 9 am use about 100 sms and 10 minutes phone call with all the auto data off,just manual check weather and email twice still have 80% after 3pm.

turn off voice commends - this will help

Its getting better
I have recently done a few things to help the battery. I adjusted the the screen brightness to a comperable setting that a friend of mine has his set to on his iphone3gs I did not do anything to the 3g settings or anything like that. I set me email to sync every 4 hours. But my hotmail I just click send/receive and sync it myself. I play music all day on my phone. Check twitter internet facebooks while music is playing and a lot of texting over a hundred sent and recieved daily. Before I made a few tweeks it would kinda die quickly but now it appears to be a lot better.

My batter DOES NOT LAST FOR CRAP!!!!! I took it off charge at 8:13 and at 10:30 i checked my phone, it went from 100 percent to 81 percent. HOW DOES IT GO DOWN 19 percent in 2 hours when i didnt even USE the phone, i just hit the backlight to check the time, this battery is unacceptable everytime i check the phone the percent has dropped

Do you leave 3G turned on? Do you have your e-mail and/or weather checking themselves automatically?
The phone can certainly be doing things that consume the battery, even if you're not manually handling it at the time.

I don't understand why battery life seems to differ so much from phone to phone. My battery life is excellent and I use it a lot. I do have to charge it every night but I expect that from a smartphone. It always lasts me throughout the day with music, videos, calls, texts and web use on 3g. I couldn't be happier with the battery life of my phone.

PLEASE give me good tips how to save battery? BTW im using ENERGY's latest rom with cookie 1.7. i dont understand why i have to stop my email and turn off 3g when this phone is MEANT for these features. theres no point of a having an excellant phone when you cant use its features to its full potentiol without having it die within 10 hours( with moderate use)

Battery is weird
The other day i charged my hd2 fully then got on an airplane all connections were watch from paris with love which looks great on the phone landed after an hour and a half and my battery life was down to 15 percent i think i might have a bad battery when i am in the car i leave it on the charge and when i am in the hotels that i stay in it stays on the charge or plugged into my laptop and thoughts??

battery life improvement?

hye,
I just bought a HTC leo which I really love.
but there is just one thing I'm concerned about, the battery life.
with my htc touch pro 2 I was able to use my phone 2 days before recharging but I can't do that with the htc HD2
IS THERE A WAY TO IMPROVE BATTERIE LIFE?
thanx

use less of your phone the hd2 drains the battery and is very good at that.
Or you buy another spare battery to switch with the exausted one when you're on the go, they're pretty cheap on ebay with a mains charger

only tips, would be turn all you're updates off, i.e, email, weather, twitter, stocks etc. screen brightness, not much else really, i get a full day out of my battery with everything turned on and full screen brightness so im happy

switch off 3G whenever there is no need for it, best is using a tool like wmlonglive to do this automatically. Will improve the battery live especially if signal strength is changing often between 2G and 3G

don't use windows live push mail, it will improve your battery dramatically
edward

my HD2 just takes 30 minutes to drop from 100% to 70 % .....
from the bottom of my heart , i want to say , htc fone ..... not good as they say ,
crap
battery drinker
just after some games , it hots ...............
will change other fone ,

I do not have a problem with the phone. it lasts me 2-3 days depending on where i am. thus depending on phone signal strength.
Further when you want to improve battery life look at the treads about that. there are so many with so many suggestions. quite a few have improved my battery dramatically. search and try.

@Felix
Are you using a Stock-ROM?
When yes, then install atleast BsB-Tweaks and activate the powersaving settings ... (the most cooked roms already have this settings)
It will bring some extra minutes/hours
My HD2 (fully loaded over night) is at 77% after 8 hours and some phone calls (ca. 30 minutes), sms and some gaming and surfing
@enchanter
yes, it drains the battery pretty good and yes its becoming hot when you play games or stuff ... but what is the problem with it?
We all knew this - before we bought a HD2

ha ha , Pliskinius has the coolest answer
" what is the problem with it?
We all knew this - before we bought a HD2 "
u right man ,

@ pliskinius: I don't know what a stock rom is... it is the rom who was installed when I bought it.
my battery lasts one day and a bit, so there is not really a big problem, but when you go somewhere and forget your charger...
@enchanter: I'm really pleased with my htc, its my 6 or so and they become nicer and nicer..

Try this fully drain the battery until the phone shuts down then take out the battery for two minutes,put the battery back in (DO NOT TURN ON THE PHONE) and charge until the green light comes on, take out the battery for another two minutes then put it back in and start up, this should improve battery life.
Also other factors affecting battery life are the Rom version,Radio and HSPL.

nice idea @nosh - will try it too ... maybe it brings some extra minutes

you are using a stockrom (stockroms are the original ones, wich are installed when you pick up a new phone)
get this little tool http://forum.xda-developers.com/showthread.php?t=589305 and activate the energysaving feature (will improve the battery life)

@ nosh 10: I'll try that thanks, but I heard that fully draining your battery is not a good thing.
@ pliskinius: haha, yeah I know I don't know a lot about WM

Laurentius26 ROMs get an excellent battery life. I get 2 days without deactivating anything. And everything works perfectly and smoothly. I have the 2.10.50.26 radio ROM and the Laurentius26 GoldEdition V2.0 Spike™ WWE 21899. Can last up to 2.5 to 3 days by deactivating 3G. I download weather every 3 hours, tweets every 4 hours, e-mail every hour. Then I make phone calls about 15 minutes per day, sms 10 to 20, pictures about 10, surf with Opera about 30 minutes per day. Remember also to close all unused applications (for me the best task manager is the Touch X manager that is on Xperia X2, lets you choose between short click on the cross to minimize the app and long click on the cross to close the app).
Edit : It's now 15:50. Was 100 % yesterday evening by 22:00. Now it's 73 % left. But I only used my phone since that time to make a countdown for cooking at lunch time.

I'm currently in Japan, using phone on 3G, very little use, listen to some music daily (30 min) and play around an hour. I'm getting 3 days easily without a charge and could easiy stretch to 4 days.
Back in my country I disable 3G and use only 2g with auto updates on every 3 hours, no email push no twitter whatsoever, just weather updates. During the night the battery drains down by 15% and with normal usage I'd have to charge daily.
15% during the night with maybe 2 updates during the night and data connection disabling just after a few minutes shouldn't drain the battery by that much. Dunno, but I'm pointing my fingers towards 2g.
I'm no expert, actually I'm far from that, but could it be that 2g uses more power from the phone?
Without any usage at all, here in Japan, I hardly get a 10% battery drain in 24hrs compared to 15% during the night back in my country.

Maybe new comm chips Edge eats more than 3G as all the phones are now optimized for 3G, I wouldn't be surprised at all.
But one thing is sure : if you have bad 3G coverage or bad quality signal, it really drains your battery. Only way to avoid this : disable 3G and you phone will stop changing from Edge to 3G or HDPDA several times per minute.

I'm using WMLonglife, and I've set it to 3g only. Now I have no idea if here in Japan they have HSDPA or Edge or if the software is keeping the phone on 3g, but I haven't seen the phone changing from 3g even when the reception went down to 1 bar.
But i'm pretty impressed with the battery life at the moment. Pity i won't have the same battery life back home.
