Hi
I have read a lot of threads about short battery life, but so far none of those applied to me. I have recently purchased this great device, and normally it gives me 2 days of usage time with a fair amount of fiddling etc, and no activesync. Now the main purpose for this purchase was the Activesync feature, as I have an exchange server pushing me my mail. I have the following settings:
Exchange 2003 SP2 without SSL certs/encriptions
Active sync set to download mails upto 0.5KB and from all times, not only the last 3-5 days, etc.
Active sync is also set for immediate retrieval, which leaves the phone with a permanent GPRS connection. There are PEAK times set, from Monday through Friday between 8AM to 6PM. Off peak times it gets it at every 2nd hour.
My battery lasts 12-14 hours like this, and I dont touch the phone much, plus dont have more than 20 minutes talk time per day. Yesterday I arrived home at 10PM with a dead battery already. This is really bad that I cannot even make it through a single day.
An addition to this the phone gets really warm, but only at the very end of its battery-life, lets say from 30% to 0 it goes in less then an hour or 2, and warms up pretty badly.
I also have the BandSwitch utility keeping my phone on GPRS only, and killing idle connections that are non-used for over 2 minutes. This I guess only takes affect during off-peak hours, but even in those hours, when I check my phone I can see a GPRS connection on for like 20-30 minutes. So I guess Bandswitch doesnt always do a good job.
Any hints? This is really annoying,
Thanks a lot,
Ben
How much backup do you guys are getting from the phone? I have to charge everyday.
And another question- The OS is very unstable,sometimes screen gets freezed. Is their any other Official ROM available for this phone which will not create those bugs?
Thanks in advance.
Umm, a whole day for the phone is pretty good; on 3G I get less.
And I have not a single crash yet, running the stock UK Rom; TouchFlo 3D has crashed on me, but I don't consider that the ROM's fault as I added that...
2-3days with two email accounts checking every 30mins and bluetooth on half the day.

2-3 days !! oops. then whats wrong with me? i am somehow getting 1-1/2 day maximum. I just installed 2 extra apps,they are -1.Battery status indicator and 2.Xperia Tweak. That's it. What's the prob? Please post some idea..
My battery was better for the first few charges, when I got 2 - 3 days between charges with heavy usage. Now I get down to 40 percent in a day, with moderate usage (3 hours MP3, a few texts and calls, some RSS reading. It's good enough, but I gather some people get more. Perhaps it's the apps in the background.
for me its up too two days with email checked all over the day, some web browsing but little call time
3/4 days (till it comes to the red). Constantly on 3g/h. E-mail, sync, weather update+stock once in a hour/2.
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??
The following thread on the XDA Desire forums was pointed out to me on androidforums by marabuchi. I did what was recommended and everything seems good so far.

"UPDATE APRIL 28 2010: PERMANENT SOLUTION FOUND?: Remove Flickr Sync. Go to Settings>Accounts & Sync>Flickr. Then press remove account at the bottom of the screen and reboot the phone - Please report back in the thread if successful! "
I don't have Flickr sync on anyways haha.
after a week of haveing it I stopped messing with it every 2 seconds... and dont have your accounts update every 15 minutes all it does is eat away our battery... I have all mine set for every2 hours and my battery lasts just fine unless I'm playing a game or something ... I even use slacker radio for over an hour a day and it barely used up 2% of my battery for the day
I realize that not everyone is having this issue specific issue, but this sure helped my battery life.
I am now at 31 hours uptime, 2 hours awake time since the last time I charged my battery. My updates are at 4 hours (I'll normally go into the app and refresh), GPS is enabled, Always Connected is on, and I use the phone pretty regularly throughout the day. I have 5 battery bars currently.
Anyway, helped me, figured someone else might be in the same boat.
Thanks
Didn't change anything for me, my calender was normal.
I get probly like 14 hours max on my battery, gps off, always data off, wifi off, screen low, only thing updating every hour is weather. I mostly text and do some web surfing, seems quite a bit low of battery life.
Gmail or Exchange?

I have Google set to sync gmail, but not contacts/calendar. No exchange, and have Hotmail setup with manual refresh.
As a quick update, battery life for me has still been great with pretty much everything turned on. Going about 2 days before having to charge.
It is now still showing 23% charge with regular usage.
WIFI always on and auto-connect when in range, GPS, Bluetooth always on. Facebook and Twitter set to refresh every 5 minutes. Played a bit of Krazy Kart, some web browsing calls txt's and so on.
Running JPC 2.2 unrooted no lag fix etc.
Quite chuffed
interesting...
do you have sync stuff set at every 30 min or every 60 min ?
i have all my apps sync every 30 or 60 when allowed
battery last half a day as in 12 hours
need two pack every for a full 24 hours
All apps that need sync are set at 5 minutes. I cannot remember what I set Google to sync to but it will be whatever the minimum time is.
This is getting unreal. OK charged up on Friday night overnight with clock on and unplugged yesterday (Sat) morning. Light to medium use and tonight as I type it still shows over 30% charge left. Thats's 38 hours and counting so far.
Am I alone in thinking this freaky for an Android Smartphone?
