The various theories kicking around are that the problems with battery life are to do with the way the OS is interacting with the kernel... so for example, a lot of people (including me at first) are having a lot of problems with the phone not sleeping properly when the screen goes off.. although I think that may be "fixed" by setting the wifi sleep policy to sleep when screen off (at least for me anyway!).. my phone is now at 36 hours up time.. now at 22%.. not used it extensively.. but the phone is reporting 15 hours "up" time out of the 36 hours since I took it off charge..

What have I done??

Task manager - killing Moxier (a test I did showed that this was causing a higher drain rate, even though I've never configured it to work!)

Wifi on all the time - sleep policy set to sleep when display goes off

Email app configured for my hotmail account - syncing every 30 mins.

Timescape and Facebook set to update hourly.

GPS off - expect when I need it.

Location services off - except when I need it.

3G/ GPRS on.

Google sync - Background data ON

google sync - Auto Sync OFF

Screen timeout - 1 minute.

Screen brightness - I have a widget I use to increase and decrease the brightness as required - generally set to minimum when indoors..

Haven't formatted the SD card - but I did copy, then delete the software off it that comes preinstalled..

on build R1FA016 (and hoping for the new "B" build soon!)

No longer using Gmail...

Hope some of this may help!..

On the battery use front, the following was posted over at SE-NSE.net:

Sounds good if it proves true, and comes soon.

Finger crossed.. touching wood!!
[XPERIA X10 General] mobz:
Just updating. Mine's on 48% after 12 hour of fairly intensive usage including games and Wi-Fi. I also think the GPS is used at some point..

Guess this is not bad, for the same battery that also powers X1.. Got a worse usage on that phone sometimes..
[XPERIA X10 General] orochiguyver:
When I first asked for battery models it was so that I could see if different batches of batteries were giving better life after a collection sample was posted. I am hoping my battery is a duff so I can exchange - Ive had enough now so I am exchaging my X10 for another one this week.

Im not going to ask for proof etc, but I dont see how this phone above all others could give you 4days with use considering my old k800 barely managed that but if so - good on you. The reason many are suspicious about such claims is because many agencies that work for brands (esp PR agencies) will "astroturf" and comment as "fans" to diffuse chatter. For my sake though can someone (anyone) with a battery life over 30 hours take a photo of the System>About Battery screen that shows the up time since last charge together with the usage info - VERY curious to see the power spread between apps on these phones - itd be a big help for comparative use!

My battery today lasted for about 17 hours - absolute crap. If that post about them working on a fix was genuine then it cant come quick enough! Though I find it strange they do not post elsewhere than Facebook to let users know.

hi

only discovered this forum last week when i got my x10. i was looking for some advice with how to deal with the horrible battery life. same problems as everyone else on here - battery going down 30% over night, only lasting 15 hours max, etc

nothing i tried made any difference (tried loads of different power saving apps etc) untill someone suggested 'Advanced Task Killer', installed it last night and my battery only lost 5 or 6% in 8 hours untill morning, i have now been using it 13 hours today (what i would say moderate usage) and its still only at 50% - thats 20 hours since my last charge.

i still cant believe it myself but it must be the app i installed as i have made no other changes. i'll add the following info just incase your wondering:

*screen brightness is reduced as far as possible

*i dont use wireless internet or bluetooth (aparting from sending the odd tone to a mate)

*on Advanced Task Killer I have set it to kill everything when screen turns off aprt from facebook and email updates

one thing i did notice was when i was listening to music for about 15 minutes the battery went down around 3 or 4% - maybe this has something to do with accessing the memory card? (this was mentioned a few posts back)

i am attaching a few photos (battery serial number/details, power usage screen, etc) here because i know a few people are getting pissed thinking others are lying (i was feeling that way untill today!)

any questions just ask although im no expert - i just done the obvious power saving things and downloaded ATK

...can i upload photos from my computer here?
[XPERIA X10 General] feeny:
UPDATE:

i have added the pictures of the battery details to my profile if you want to have a look at them.

interesting though (bad interesting), my battery has also gone down 10% in the past hour but the only thing i did was increase the screen brighness to full (in order to take photos of the battery status) and have a 10min phone call (forgot to mention earlier, i dont use my x10 to make many calls, mostly just texts,emails,facebook and internet). so obviously the screens brightness/calls are a major factor...either that or i've jinxed myself :o(

hope some of this info helps!
[XPERIA X10 General] orochiguyver:
Thanks feeny really helpful - also very jealous! no way mine would last anywhere near the 20hr mark!

What is the icon / app that is indicating the battery health and charge you have on your task bar next to the advanced task killer?

Also do you have:

Timescape Facebook auto updates on? if so what interval?

Timescape Twitter on? If so what interval?

Have Gmail app on background push check? If so, what interval?

Have an email account linked on your Timescape?

Have Facebook app installed and ob? Is so (yep) what interval?

Are you always set to 3G mode on?

How long have you had the phone?

Sorry for the ton of Qs, just REALLY desperate to get to the bottom of this battery mess!
[XPERIA X10 General] feeny:
no probs with the questions

its an app simply called 'Battery Indicator'

Timescape Facebook auto updates on? if so what interval? - 30mins

Timescape Twitter on? If so what interval? - never,just update manually (dont use much)

Have Gmail app on background push check? If so, what interval? - no, data sync is off

Have an email account linked on your Timescape? - yes, 30min

Have Facebook app installed and ob? Is so (yep) what interval? - yes,30min

Are you always set to 3G mode on? - 3G always on

How long have you had the phone? 1 week

realise i have a few of these things off but i also browse the net quite a bit during the day (using 'opera mini' mostly). location services are off except when i need them too.

only thing im a bit annoyed about atm is the power usage of the music player. must be something to do with the memory card that was mentioned on the last page, but i'll try reformatting it or something

goodluck!

Hi

I was following this topic for a while now and today I decided to share my experience. Firstly, sorry for my bad english.

I have my X10 for 2 weeks now (tomorrow it's the 3th week) and I have to admit - the first 5 days I had horrible battery life. On my first charge, I barely got 12 hours out of it - this was with wi-fi and 3g enabled. My second and 3rd charge wasn't that great either. The 5th charge on the other hand was one of the best. My battery lasted about 22-24 hours on moderate usage which I must say, was OK (just OK). Then later I decided to disable wi-fi and stay with 3g only for internet hence I do got a data plan anyway.

Now I am on my 12th charge, wi-fi disabled, 3g on (but I do turn 3g off at night when not in use) and my phone is up for 3 days now and still got 24% left (I uploaded some photos in my profiles photo album - I made them public so you can find them there). I use my phone quite a bit - mainly for phone calls, texting and some surfing (I use Opera as my default browser). Also I have to add the fact that I have every synching off, push mail off, auto updates off. Timescape is the only software running which I left updating every so often. The only thing that bothers me is that the phone cannot charge while being off. I usually charge my phone overnight and in the morning when I unplug my phone, it's on 95%. That's 5% waste because the phone is ON while charging. I think, if the phone would be charging while offline, it would keep the 100% charge which would be much better.

Anyway, as an owner of the X10 I must say I am quite satisfied with the overal performance of the device. There are a few things I would've change - for example, the in-call volume is kinda low and Mediascape..well, as a sound-lover I must say, Sony could really add some sound enhancers there - an audio equalizer, a clear bass, clear stereo option for example.. . My wish was to replace my Sony Walkman X player with this because I didn't want to carry them both while walking. I tried the X10 with different headphones/monitors like the Sony MDR-ex500 and ex700 but the sound still isn't as "natural" as I would like but with some equalizing I think the X10 would sound great.

Anyway, as a phone it's a great device. It still needs a little polishing here and there but overall it does what it needs to and I really like it so far.

Regards
[XPERIA X10 General] ShadowFlare:
I think one of the reason the phone is ON while charging is so that it can stop the charging once it hits 100%, and starts recharging again when it has depleted to 90% or 95%, not sure which.

X10 is my first Android phone, so I can't compare it to other phones. I do have X1 and the only thing the X1 excels over the X10 is the battery life, that's all. But not by much.
[XPERIA X10 General] thymus:
i have question to ask you guys.

what happens to battery life if gmail is trying to pull mail when 3G/Wifi is off?

well...my setting is to pull gmail every hour but 3G/Wifi is off at night and was wondering if email app is actively looking to pull mail and as a result it causes battery drainage when data is off.

just curiosity.

thanks in advance
[XPERIA X10 General] saltorio:
Just to note, SE made an announcement regarding software upgrades for the X10 series (including that Android 2.1 will be released in Q4), and as part of that announcement stated the following:

So stay tuned for those details, but I'd have to think that the patch would include battery drain fixes.
[XPERIA X10 General] cashaw:
I am sure it will ! I took a quick glance at the HTC Incredible forum today and they have a 'power issues' thread which is almost identical to ours.... They seem to be getting 10 hours max and the workaround seems to be to buy a second charger :-)

I don't want to rub it in too much but I am currently on 22 hours with 54% battery remaining so I am more than happy..

10h on Incredible ? :eek:

That's crap.... way worse than X10.

I'm curious how long a Desire (or N1) lasts with WIFI 100% on and bluetooth for about 8h/day :)

My X10 lasts about 12h in this conditions.

If i use the USB cable at work, it goes up to 16h ... which is not bad at all.

Problem is in weekends :) because even if i stop WIFI when i don't use it... it seems is not really stopped and still drains battery if i don't reboot the phone. Which doesn't make things any better because reboot uses a lot of batter too.
[XPERIA X10 General] cashaw:
Well the N1 does not seem that much better, (again quick glance) and most users seem happy enough with 12hours a day and seem to understand that they need to find some way to charge it during the day.

Although we are complaining about the X10, if anything for a smartphone I think many of us are getting a better battery life than with other recent smartphones, or at least similar...
[XPERIA X10 General] lornova:
Now I'm at 26% after 28 hours, and it is quite satisfactory for me, too. However, the question is: what caused my sudden change of battery consumption? It changed overnight from 10% per hour (even in plane mode!) to less than 3% per hour. Actually, that happened after I "repaired" the phone with SEUS (flashing the stock firmware I already had), but now I've the same settings as before and the same apps installed, so what? The cause is for sure not the battery, because I had the same fast draining both with the X10 battery and with my old X1 battery. I really don't know what to think...

By the way, I don't reboot after the charge (unfortunately this tip was not helpful when the battery was draining fast).
[XPERIA X10 General] lornova:
I tried that when my phone was draining 10% of the battery per hour with very little improvement.
[XPERIA X10 General] im_iceman:
What do you have your wifi sleep policy set to? Once I'd set mine to sleep when the phone screen goes off, the battery drain issue stopped almost completely...

As for HTC - Can't comment on the Desire, but I got my wife the HTC Legend.... Juice plotter shows her battery life as c.100hours when you take it off charge... however.. she doesn't use her handset like we use ours!!.. it mainly sits on the side in the kitchen.. not doing much.. although.. she does have everything syncing hourly, BT on, Wifi on.. 3G/ GPRS on.. all the time.. When her phone sleeps... it really does sleep!!!!!.. That's all I expect from mine..
[XPERIA X10 General] lornova:
Actually not 30 hours but 28... sorry for the shaky pictures but they're taken with my X1 :p

I've reached that with:

- GMail in push mode

- BT off with exception of 45 minutes of A2DP music streaming

- GPS off

- WiFi off with exception of 1 hour when I unsuccessfully tried to download Collins dictionary

- A couple of SMS and no phone calls

- Beautiful widget on home page with weather update every hour

Just been visiting "the dark side".. or HTC Desire forum to be more specific.. they have this thread going on power issues...

Seems they're having exactly the same issues.... so anyone thinking of switching... beware!!! it appears that the grass really isn't greener!
[XPERIA X10 General] dermon:
I disabled the Location thing. the battery improved considerably. i guess it used the cell broadcast function when i had the wifi turned off. and it does that with the screen locked also, but you don't actually need it. so just disabled it.

Thanks everyone for replying and giving their 2 pence.

I think I will exchange my X10 for another one this week as Im still within my 28 day period. Im hoping this quick fix SE mention will be a direct fix for the battery as for me the hang ups in order of annoyance would be:

1)Battery life

2)Battery life

3)Battery Life

4)Dodgy Timescape when its syncing (ie. whenever you first click into it) for afew secs

5)Occasionally unsmooth unlock (not the dot pattern the swipe)

6)MediaScape being an unfinished app with so much potential (Equalisers and the basic ability to sort by Artist, Album, Dates etc.)

7)Battery life

Today my X10 died listening to music at 18.5hrs best yet but nowhere near some of you lucky ppls level of life!

Question about overnight settings - is everyone getting over 20h switching mobile signal completely off or setting it to 2G?
[XPERIA X10 General] tuxStyle:
Policy is always on :)

And really is always on ... 24h/day because 22h/day am near a wifi hotspot :)

Problem is in weekends when i'm not home and even if i turn wireless off completely i don't see any improvements unless i reboot the phone and never start wifi till i come home.
[XPERIA X10 General] im_iceman:
hi, you should go into wifi settings, then press the menu button, select advanced settings. Change your wifi policy to sleep when screen off. Background syncing still works. Then when you want to actively use the phone it switches wifi back on. Saves loads of battery.

[XPERIA X10 General] ShadowFlare:
We need a battery a full-sized length of the back of the X10, probably equals to 3200mAh. That way we can switch on ALL wireless features and have them synch/push non-stop and battery will still last the whole day. Problem solved, yay!

It does suck to have resort to switching features off.
[XPERIA X10 General] proatiku:
i gotta say to all those still complaining about the juice running out quickly, try to uncheck Automatic Search for Software Updating in settings. that should atleast extend it by 3-4 hours or normal use.

Turning off 3g connection has been life saver, the battery lasts even days without but its sad to have so awesome phone and then the battery is such a joke :(

[XPERIA X10 General] lornova:
Thank you for sharing your story! Mine was exactly the same. I can however confirm that formatting the SD does not improve battery life, for me the battery life improved instantly after the factory data reset (actually, I reflashed the device with SEUS, but the result should be the same).

So at the end, I think that in the X10 FAQ we should put the suggestion to immediately factory reset the phone after the purchase, just in case...
[XPERIA X10 General] lornova:
Have you tried to factory reset the phone? I'm now running for 2 full days with 3G (with data connection) always on.
[XPERIA X10 General] cashaw:
With 3G it always comes down to how strong the signal is in your area, strong signal and it's no problem. If the signal is weak and the phone is forever handing off between 3G and 2G then this will drain the battery.

I discovered wth my old phone and if I left it overnight in my kitchen where 3G is weak, the battery was always dead in the morning. In the hallway where the 3G signal is strong, the battery would last for days on standby.
[XPERIA X10 General] hugorunes:
Battery useless

I've had the x10 since saturday, having to find myself recharging every night and go college and when i get back having to recharge again, i know that battery does drain a lot more with smart phones but still no excuse i dont want people telling me turn my programs off and turn wifi off and 3g because i need them and its also features of the phone so can anyone recommend other ways of saving battery ?

I also have the battery from my X1 which currently using to see if its any better
[XPERIA X10 General] lornova:
I've a 3G-only operator and to prevent roaming to 2G operators I've selected "WCDMA only". At home I have poor 3G quality but this seems not to impact on battery life.
[XPERIA X10 General] tuxStyle:
I can't find this option.

In which submenu is hidden? :o
[XPERIA X10 General] Phantasm4489:
It might be down to something other than just signal quality then. Not sure what it might be but it does tie in with my experience.

When I put my phone into GSM only it lasts 2 to 2.5 days. When i change it to WCDMA only it lasts about a day. I live and work only a mile or so outside of the city centre and the reception is perfectly fine.

I'm going crazy!!!

My Xperia X10 has loosing 10% of battery in 30 minutes!!! In standby!!!

Sony Ericcson, what the hell did you've done?
[XPERIA X10 General] saltorio:
Sorry for such a basic question, but what exactly does this option do? Is it simply for Android to check for firmware updates and the like in the background, or does it also apply to things like app updates via the market?
[XPERIA X10 General] im_iceman:
I think that this is a red herring - I've tried it in GSM only mode and also in GSM/ WCDMA preferred mode.. and battery seems to last about the same.
[XPERIA X10 General] ShadowFlare:
This is to search firmware updates, and maybe patches for the Android OS.

For App updates, simply have your X10 connect to WiFi or 3G, open up Market, then you'll be notified if there are updates to your apps.
[XPERIA X10 General] saltorio:
Cool. Thanks for the info. I new about how to update Market Apps, I just wanted to make sure I wasn't disabling that functionality.
[XPERIA X10 General] tuxStyle:
A bit off-topic but if we are talking about that option ...

I get network error while manually checking for updates.

I'm on WiFi and network connections is fine.

WTF?

Anyone with a branded rogers can check if is working for them?
[XPERIA X10 General] saltorio:
I just checked and it works fine for me over 3G on my Rogers-branded phone. Don't have a WiFi connection available to test though.
[XPERIA X10 General] im_iceman:
Here's an interesting thing I've noticed...

When I have wifi on.. the phone sleeps and will use virtually no battery for hours.. but when I'm at the office with wifi off, but in a stable 3G signal area.. the battery drain occurs more noticibly.. not significant like it was when I first got the phone.. but it's probably twice as quick as when Wifi is on.. Think I might try leaving wifi on next time I go to the office..
[XPERIA X10 General] Cryson:
Normally the phone will turn wifi off in standby.

[XPERIA X10 General] phillcX10:
Following up on my previous post, I managed to obtain a full 37 hours on the last charge. When I received the 5% warning I put it on the charger.

Today, things don't look so good. I've had the phone unplugged for less than 8 hours, and I'm already down to less than 33% battery life remaining (again estimated from looking at the battery icon). I'm expecting it could be flat before I make it home this evening.

Battery Use breakdown:

Cell Standby: 31%

Phone Idle: 28%

WiFi: 11% (time on registered as 2h 35m)

Voice Calls: 10% (14 minutes)

Display: 8%

Android System: 7%

Games: 5%

Browser: 3%

So, the big difference here today, when compared to yesterday is the WiFi use. Although, I've also had GPS turned on, which I didn't yesterday, but this doesn't register in the battery use table. It looks like the WiFi does suck battery life badly. Next charge I will adjust WiFi setting so that it switches off when the phone goes to idle for example, and as documented elsewhere on this thread.
[XPERIA X10 General] Cryson:
Yeeees!!!!

I have the solution for the power problem!

The problem seems to be a background process during standby.

My solution ist, that you're are using the "advanced task killer" (free in android market). Here, you're are turning on the autokill feature and you're setting it up to autokill when screen turns of and the agressive mode.

After that, you're Xperia is lossing 1% of battery in 2 hours in standby.

This means, that you have a standby time of about 200 hours.

Try it. :)
[XPERIA X10 General] phillcX10:
Totally flat after 11 hours today. Constant WiFi on I think had a massive effect.
[XPERIA X10 General] cashaw:
I am suspicious of task killers, they may be killing tasks which are,actually needed.

I've never known a Unix based device which needs a task killer, unless a task has gone AWOL.

[XPERIA X10 General] saltorio:
I use a task killer (TaskPanel Lite) purely to keep Moxier and Timescape in check. I don't use either app, and they have a tendency to launch themselves regularly and east battery power. I'm hoping I won't need it once the new "performance improvement" firmware is released (in the next few weeks), but until then it does help my battery use.
