I am using the CDMA hero, but this should apply to anyone with a Hero (although our GSM friends have probably figured this out long ago.) Feel free to move my post if you like.
So I too was experiencing extreme battery draw down. I considered the SMS issue with perpetual awake times but after isolating the issue, I was still hitting 30% after after 12 hours with only moderate use. I found that unacceptable considering my Treo has been in standby for 2 weeks now and the battery has not budged. Solution? Turn of Google background services.
I know it hurts to have to manually refresh email, contacts, and calendar, but the return is almost zero battery drain (unless you are actively playing with the phone.) I know this is an obvious fix and I read it elsewhere online when I first got the phone. However, I am addicted to Gmail so I was really hesitant to turn it off. The background services option seems to keep a constant data connection when I really just want it to check my email every 15 minutes or so and update my calendar and contacts once a day. Has anyone found a way to limit the update frequency without the HTC widget. (I prefer the stock Android Gmail client.)
I do not know about the frequency of Gmail syncing,
but the main battery saving trick for me
is to turn the mobile data connection completelly off
when i know i will not (or want not) to be online
for a longer period of time (e.g. in the night, longer car drives, etc)
i am using the build-in htc widget for this
Thanks. That is a pretty good solution. Still wish I could curtail the sync frequency though......
So we need to re-enable it when we want to visit the Market, right? Annoying but if it improves battery life, then not a big deal.
Hi guys, please bear with us on this one.
This is my 2nd Android phone, I used to have an Hero about 6 months ago. i really liked the front end but the screen was small so I upgraded to an HD2 which I still have. On the HD2 the screen is huge but Win Mobile lets it down a bit. The marketplace is expensive and very limited and the amount of apps for Win Mobile seem to be getting less and less, especially supproting the 800x480 WVGA screen on the HD2.
Anyway I was due an upgrade and Orange offered me the X10 for £20 which i couldn't refuse. I am trying to like the phone but the biggest issue for me is the battery. I did the usual of leaving it plugged in for 16 hours as recommended by orange etc. If the phone is on standby I seem to get around 8 hours and the battery will be down to about 40% remaining charge. That is on standby with the top button pressed and the phone on a black screen. This is really poor considering the HD2 can run almost 2 days on standby before loosing 60% of its charge.
Anybody got any suggestions on how to improve this? Would it be wise for me to do the debrand as mentioned in other threads? It is currently on build R1FA014.
Thanks for the help.
The battery will improve in time, after a few weeks of use the X10 will loose 1-2% of battery each 2 hours (at least my X10 R1FA016 and two of my friends X10 R1FA014 do). This is with 3G on, wifi sometimes on, GPS sometimes on. Just give it some time. I think the X10 is one of the best smartphones out there. There is an extensive thread on Power Usage which can be found here: http://forum.xda-developers.com/showthread.php?t=657265
In the end it comes down to:
-Give it some time
-Disable auto search for software updates (settings>about phone>update)
-Wifi seems to drain sometimes
-Streaming drains.
Thanks for the pointers Vin87, I have got wifi turned off now but I am at work for the next 7 hours and I only have about 28% charge remaining
I'm going to have a good read through the thread you mentioned all 50+ pages LOL.
I do like the phone and for the cost I am going to keep it and hopefully we will get some new updates soon?
It gets better...way better. 13 hours since my last charge, and it's at 71%. I've been using it every now and then, Facebook, sending emails ect.
Great battery life now!
From a work perspective, I miss the X10 having a dock.
With my G900 each time I returned to my desk,I would throw it the dock and so it was receiving a charge throughout the day, the X10 is more fiddly as you need to play around the the flap and then figure out which way to plug in the mini-USB cable...
I wish they had chosen a better connector than the mini-USB as the standard, as it's not that easy to quickly connect it....
I could almost throw my G900 at the charging cable and it would connect.
Basically (if you want to use the smartphone):
1. In the beginning you will use the phone a lot. Installing apps, trying apps, games, music etc. so the battery drains faster. When you will stop pushing the phone to the limit will be better
2. Wait for a week, the batter will get better.
3. Get a task killer/boot manager and set it to autokill moxier. Don't kill other apps
4. Set facebook/twitter sync at 1h (or more) if you are not a hardcore fan of this social platforms.
5. Email: if you need instant notification there is not much you can do. If you don't need it, disable background sync and sync manually.
6. Disable location using wireless networks.
7. Wifi/3G: if you need instant notifications, wifi will drain your battery pretty fast but if you don't have 3G data plan like me, there is no other choice. If you have a good 3G plan, you can set wifi sleep policy to turn off wifi when phone goes to "sleep". Also, you can use this together with Juice defender free to turn 3G on 2 min every 3min to get notifications so, you will save even more battery.
8. Enable bluetoot/gps only when you use them and keep them disabled when not.
9. Set brightness to manual and around 25% when you are indoor and "sleep time" (screen timeout) to 30sec
10. Oh, i forgot, disable search for software updates and if you didn't install too many things, try a factory defaults. Some people did a SD card format (be sure you save everything first) and reported battery improvement.
If you want to use the dumbphone inside then turn everything off (BT, GPS, 3G, WIFI, Twitter/Facebook, email, background sync, etc.) and your dumbphone will last way longer
I am using CMN 6.2.0 v2.0 with radio 2.15.## (can't remember the other numbers). In standby, I get somewhere around 2-5 mA (according to current widget). My battery drain in an hour is around 8% in standby. From what I can tell, this is not ordinary. My display is set to the lowest brightness settings. What I am syncing is my facebook (every hour), gmail, google reader, contacts, calendar, launcherpro facebook (every hour). If I am actively using my phone, it'll lose like 25% in an hour. I have MAGDLR 1.12. This is about the same battery drain as when I used HD2One for the SD card. What am I doing wrong?
Update: I do use Titanium back up to restore apps, does that have an effect on battery?
no answer, just some tips.
First, do not forget that battery drain is subjective (it's directly link to your usage of the phone).
I don't know your ROM, NAND or SD?
try to switch of things one by one:
Start in flight mode (check drain),
switch of data (keep only phone),
activate data but stop the auto synch of all your stuff,
put them on, one by one.
(do you keep wifi on?)
It will also depend of the strengh of your network. The weaker it is the more power your phone will use. If you're between two cells it can keep switching from one to the other.
I'm using Gauner NAND and it impressed be. In flight mode I loose around 3% over night.
Let also some time to your phone to "stabilize" after flash. Don't know why but after fews days my power drain has improved a lot (battery calibration maybe?).
hope this will help you.

My ROM, NAND is in my signature. I have put it on airplane mode from 2am-7am which it only lost 2 % (so im guessing it's something to do with data/sync). At home I use wifi, at school I use data. I will try turning off 3g and i'll try turning off sync. But the only thing I ever sync is gmail, contacts, calendar etc. I will attach my app list. I already read that URL and have done it many times, still lose 8% an hour.
HTML:
http://www.appbrain.com/user/jasonvvong/1-22-10
For all these people that claim to get 2 days out of their hd2, do you turn off 3g or sync or put it on airplane mode? If so, doesn't that really defeat the purpose of the phone? If you have to turn off imperative functions of the phone to have it last longer that 12 hours (that's how long I get with my phone), it seems pretty counterintuitive to have a smart phone because when I need to check my email, the internet, etc, I can just walk to a library or a computer lab and look at it there. It defeats the convenient nature of a smart phone.
At least in flight mod it seems ok
I have data always on, but when I install my ROM I setup to NOT auto synchronise. I prefer to know what my phone is doing. I'm not very good (yet) with Android but a lot of things seems to work in background.
I check my mails, use phone and it last more than one day without any problem.
Try to disconnect the auto-synch and activate the sync only for what you need (for me just mails and stock), use the smaller frequency you need. No need to update your mail every 5 mn if you check no very often for example.
Sorry but no other advice. just try to isolate what drain your battery.
When I read this "But the only thing I ever sync is gmail, contacts, calendar etc." check the frequency. If it's very often and with a lotof data, it could be a heavy usage.
Go to settings, about, battery use. That may help identify if there's anything chewing your battery up. I suspect that it will show the display as using the most power, which is normal and not really much help. Worth a look though.

I have found the solution for MY large battery drain:
The problem has been, that my phone used 5% of battery per hour when it’s merely lying around. The battery graph was a straight, quickly decreasing line. So the culprit was not something that happend from time to time but always.
One very disturbing thing: The indicators below the battery graph shows when phone, Wifi and the screen were on. In additions it shows when the phone has been awake.
Even if the screen was off and I did not touch the phone, the „Awake“ indicator constantly showed every minute for a very short time. So the phone never went to sleep, it woke up constantly all the time. Sorry, unfortunately I don’t have a screen capture for this.
Deactivating automatic updates for applications and setting the Emails to sync never didn’t help. I even erased all the Samsung crapware from the system folder, but to no use. The battery died after one day of not doing anything with the phone.
Then I deactivated syncing of the contacts and the calendar for my WindowsLive-Exchange account and the battery drain stopped. I now have less than 1% per hour (see screenshot) when the phone is simply lying around.
So, for me the culprit is the syncing for contacts and calender via Exchange. Unfortunately there is no option to set the sync interval for these.
- Anyone can reproduce this issue?
- Is this just a problem with WindowsLive Exchange or does this happen with other Exchange accounts too?
- Is there a possibility to set the sync interval for contacts and calendar (somehow, maybe via a config file)?
There seems to be something seriously different if not broken in GB 2.3.3. Apps that work perfectly fine in Froyo are keeping GB 2.3.3 from going to sleep. I've isolated several apps that either keep the screen from shutting off or keep the device constantly awake even when it it's no longer running/cached/screen is off. And, these are programs that work perfectly fine in Froyo and do not cause idle drain. Wonder if this is something 2.3.4 addresses...

I have frozen:
social hub, email (i use another one), and few more programs that I dont use but noticed that they stay on without any reason,
if 3G or wifi is ON battery drain is prery bad, I guess this is a bug in 2.3.3 as cmd512 said.
Last night I turned off wifi and 3g and made sure that wifi share + manager are off (they can be turned off easily if u untick "use wifi" in location settings menu)
so with everything off for 7 hours sleep (dont rly need my phone while sleeping) battery was down 2% only :O
the moment I turn on 3G Android OS use jumps to the skies :X

Hmmm..it could be. I will try this also. First I just take the contacts out, because that is not so necessary for me. Calendar is pretty necessary for me and emails are a must. If I have to take the calendar out, then so be it. I will manually sync it once a week then.
By the way, I just noticed that with my gmail account the sync icon is constant in the calendar.
Now when I unchecked it and checked back it went away after a while.
I am not sure if it was sycning all the time without luck. Lets see.
I think calendar synch is on of the probleme. With calendar sync my phone drain 5% per hour in idle mode without 1% by one or two hours.
It's quite strange that there's quite a lot of these threads now all saying about how bad the battery is but I'm amazed by how good the battery is. I don't use my phone a huge amount especially at work and when I get home I use it for a quick web browse and the occasional text message and phone call. Most days I will still have 80% or more left by 23:30 having been on since 07:15. Today I checked my phone at 12:30 and the battery had only gone down 1% in just over 5 hours. All I did with it from 07:15 was occasionally take it out of sleep but not unlock it to check for any notifications. Since then I've been using the web (data) for about half hour or so, an hour of music listening and texting and right now I have 77% left after 12.5 hours off charge. Therefore I think my SGSII has the best battery life I could ask for.

Really depends on what apps you have running, as you can see from my original thread on this "Awake all the time during idle" issue:
http://forum.xda-developers.com/showthread.php?t=1094666
But in general, agreed. Once I got rid of that bug, the device has been fantastic with battery life. And, for a stock ROM, that's damn impressive!

I fully agree. Now that I don't have the "wake-up" issue anymore, the battery lifetime is almost as good as the Omnia7 -that's damn impressive for a modern Smartphone with such a hardware!
For me, I turned off my wifi, gps and "my location". And most importantly, my applications are not running when it is on idle. Go to task manager by holding the home folder and click exit all. Or you might try to clear the ram memory.
i have turned off gps, wifi and syncing but still getting battery drains can´t even last for a whole day. But I installed Litening ROM just now and see if this helps . I was on KE2 before flashing custom rom

I have noticed the same issue trying to sync to a exchange 2003 account. It seems that my calendar is syncing either every minute or about every 20 minutes. I also noticed the same issue with my gmail calendar. I have tried two different phones and reset each one several times. The same problem keeps occurring. I may have to download touchdown for email, contacts and calendar. It just sucks because then I will have two calendar applications (one for work and one for home). This is very frustrating.
Are you still having issues with echange calendar sync?
After updating to KE7, I have noticed that every time I receive an exchange email the screen wakes up for a second or two and goes to sleep again.
Didn't occur on previous firmware. Anyone else with this issue and a possible fix?
Is social hub the best solution for IM? I would like to have Yahoo and MSN messengers on always, so should I use another less power hungry client? When people mention calendar synch is it google calendar they're talking about? My google calendar is important for me, so how to optimize it?

Yes, unfortunately. I am now syncing manually with a switch on the homescreen.
I am now hoping for Android 2.3.4 to fix this issue.
Have a look at comment #290:
http://code.google.com/p/android/issues/detail?id=11126#c290
I have an X10i with Jerpelea's CM7 with custom kernel and that had a very annoying deep sleep issue (the phone never went deep sleeping) which caused the battery to drain very quickly, but Temoi19 found out that by disabling automatic time updates and manually selecting the operator, made the phone to deep sleep. So I took a shoot and tried the same trick on my new Galaxy S II and now when idle my phone barely eats power. After over an hour after unplugging I was still at 100%. I don't know if I am just lucky, but it is worth a try

I also have this issue with my sgs2. I looked into the exchange settings and there is the option to change the syncing. It was set to push, I now i changed it to manual and will report back the results tomorrow. The drain in general only occurs when mobile data is enabled here. Didn't try with wifi yet.

You can leave the syncing to push, it's just for the EMails and they're working fine.
I'd propose to disable the calendar and contact sync in Einstellungen -> Konten -> Automatisch synchronisieren

according to the logs if there are no changes in contacts or calendar both will be synced only once per day. so this should not be the issue.
Now that ICS Passion is at a point where day to day usage works pretty great, I decided it was time to track down the reason my phone never went into deep sleep. I shut down all widgets and turned off everything in the settings except basic phone functionality, then one by one I started reactivating everything. I'd do a full charge, reboot, then let it sit there for a few hours, then check CPUSpy.
My phone consistently went into deep sleep just fine and stayed there until I re-enabled sync. Now it spends nearly one third of its time at 200 MHz, and the rest in deep sleep. I expected sync to use more juice, of course, but keeping the phone awake for one third of the time seems excessive. Most recently the phone was at 200MHz for 1 hour out of a 3 hour period -- 27% of the time.
(I run with two gmail accounts -- one personal, one business. On my personal account I sync calendar, contacts, docs, and reader. On the business account it's just contacts and docs. This stuff isn't changing often, I would expect sync to wrap up pretty quickly. I don't use GMail itself at all.)
Has anybody else looked at this in detail and seen similar behavior? Is there anything which can be done to control or improve matters short of going all-manual?
digging into the details...
I'm also thinking it's time to determine what exactly is consuming my battery. The screen is an obvious culprit, but I suspect there are a lot of wakelocks as well.
What are you using to monitor your background usage? Just CPUSpy?
Well, first and foremost, I switched to ICS Slim, which was a major improvement. The developer is very active and responsive and he's focused on getting the basic platform stable and working.
From there, I just use the Battery display in Settings along with CPUSpy to keep an eye on things. When I do suspect a Partial Wake Lock, I look for them with DevTools+ which is the most direct way I've found to see a list.
Between Slim and a $16 Galaxy II Andida 2300mAh battery I've occasionally seen 3 says of battery stand-by, although with normal usage I'm getting more like 2 days on average.
