That battery is tempting me, but I'm afraid that using a non stock battery could actually broke the phone. Batteries are very tricky and fragile stuff and the charging circuitry has to be carefully designed. Lithium batteries need always an embedded chip that talks with the charge circuit and balances the charge given to the cells of the battery pack (when using multiple cell batteries, each cell will have a slightly different behavior).

So, I'm afraid that using a battery for which the device itself has not been designed for could be harmful. However, if anyone tries it and would share its results...

One little thing I noticed about that Mugen Battery for X1 & X10.... it's rated at 3.7V. I'm looking at my X1 and X10 batteries, they are 3.6V. Hmm....
[XPERIA X10 General] im_iceman:
Hi Lornova - You can set up the default mail app to pick up your googlemail.. and then disable googlemail in the auto sync - Then set your update frequency to whatever you want...
[XPERIA X10 General] yoshik777:
Hmm without any constructive?

So did i bought a phone or a smartphone? Hmm let mi think...

The battery life with basic things on is just to short for a normal use of this phone, its a fact which a lot of ppl can confirm. If You dont have this issue You should be happy but i have it so im unhappy.

For me its impossible to get 40-50% with using basic things, simplest example from yesterday : 3hours of music plus another hour of checking mail and stuff, result 13% after 7 hours.... 87% in such short time. Sry mate but this is not what ppls could accept. Thats why we are complaining for what we do have right.

Im not a HTC fan or something but the problem caused by this issue makes this phone unusable for me . Right now im using it as a backup phone, dont even make real calls, texts etc and yet a still have problems with the battery.

And yes i do use task killer and auditor, but the phone should be able to get a decent score without them.

ShadowFlare its not that i want to move to HTC its that i will have to do it.

I had a dozen of SE phones which were great, but their were working how they should but this isnt. If You cant understand this normal customer complain about faulty product its not my problem.
[XPERIA X10 General] lornova:
That's just what I don't want. GMail client is much better than default mail app, for example it lets you to do a quick search of all my old e-mail (just like the web GMail client). But I really don't understand why there isn't an option in GMail to switch between polling and push... we just have to blame Google for that...
[XPERIA X10 General] habs101:
This x10 with android reminds me of using a windows mobile device all over again

You have to close apps consatntly to get battery life in the goods.

this phone is useless if you always have to close down apps and turn off a whole bunch of features that are required for a smart phone.

the point of being SMART phone is being smart, this reminds me of a dumb phone that can't control it's things properly.

with the nexus one i haven't even installed a task killer and yet the phone runs like a champ and i use location service, push mail etc.

sony droppppppppped the ball on this one AGAIN . like their other handsets .

and we all know how updates are with SONY, good luck .

we seen how they are with the x1 and x2 maybe every 10 months u might see any update or RESPONSE FROM SONY they just dont care.

at least Htc RELEASES patches etc fast and nicely with the hd2 etc.

this x10 is far from being smart. the IPHONE is smarter and even has better battery life.
[XPERIA X10 General] im_iceman:
My phones been on 16 hours.. I've used it a lot today... Wifi's on.. sync'ing hourly (that's all I need)... 3G on.. now 40%.. seems pretty good to me.. no ball dropped there... and for the record.. if you don't have an x10.. don't comment on what you don't have first hand experience of.
[XPERIA X10 General] habs101:
before, you open your assumptions and talk stuff,

i've gone through two x10 and i am on my second x10 that i still hvae and returning it on monday

so think before u speak,

the ball has been dropped on this x10 like it was onx1 and x2 ( owning all the devices ), check the x1 section and update yours what sony thinks of customers.

watch when sept comes around and people are still waiting for a 2.0 or 2.1 update. it probably wont be available even then.

After owning two x10's and putting them through test, this phone is not make to have conversations longer than 10 minutes of multiple conversations.. it can't handle the normal task of talking. the battery drains fast.

if you leave have the stuff on that people leave on the nexus or desire without killing tasks goodluck
[XPERIA X10 General] silklee:
I bought the x10 for the primary reason that, imho, it’s the nicest and sleekest looking phone out there in the market now.

Thus, I am not using it 100% of the time like a smart phone. I do use it to surf the net, and check my mails. However for every full charge, this will probably be a total of 15 minutes or so. Main usage is really to send messages and for phone calls.

With my usage, a full charge will last me about 50+ hours. There seems to be no discernable difference whether I leave 3G on or off. Also, there also seems to be no discernable difference from the first full charge to after having ‘conditioned’ the battery for 3 battery charges.

The only time I experienced a real unacceptable, imo, drain on my battery was when I turned on the screen to not timeout while I was using “maps”. In a ten minute period or so, about 7% of the battery was used.

Btw, one question. How do I make it such that when I delete mails from my hotmail account on the x10, it will be synced to my hotmail account?
[XPERIA X10 General] orochiguyver:
Hi guys, Ive been watching this thread for a week or so now with high hopes of my X10 improving its performance over the 14-16hr 100%>0% battery life it has been giving me with moderate use.

My definition of moderate use for one day is:

Send and receive between 10-30 SMS (so 20-60 total)

2-4 phone calls (av length between 2-10 mins)

Mediascape for music (30mins)

Web (20-40 mins worth)

Fiddling around with it a few times (on off, people picking it up to see what its like etc)

I wouldnt be so annoyed with the battery life if it lasted me 20-24 hours, but 14-16 is a joke - Im at work in the daytime, and by the time I leave its down to its 30% or less mark - correct me if I am wrong, but isnt the evening/out of work hours when you tend to need it most?! Luckily I have a charger at work, but I shouldnt have to charge multiple times per day!

Aside from preferring Sony design and features, one big thing that pu tme off the iphone was its bad battery life, but its either the same as or better than this...

I love my X10 but need some kind of fix - I have task managers auto killing face recognition and Moxier but to be honest its still pretty poor - I WILL NOT dumb down the features to get decent battery life - I may as well get a standard phone if I did that to a Smartphone!

In reading people claiming to get 30hrs+ (sorry, call me a sceptic but I dont see how battery life with "comparable" use could vary THAT much from the 15hrs to the 30hrs +) - can you post serial numbers of batteries and also model numbers and country of manufacture for the X10 please? I am thinking perhaps its a hardware fault as well as certain apps causing such disgraceful battery life...?

Thanks all!
[XPERIA X10 General] Vin87:
Your batterylife will improve with time (atleast mine did). I'm now at 35-48 of use before the 15% mark kicks in. 3G is on, Wifi is on sometimes, GPS is on sometimes. The only time the battery really drains is using streaming video. I don't use a taskkiller, startupauditor or Juicekiller. Two of my friends have X10's as well. Both of those phones went from 24 hours or less to 35-48 hours too.

Numbers on my battery:

1203-8161 2 1500mAh 5.4Wh

[XPERIA X10 General] Astral07:
how do you stream video?

sorry for the OT
[XPERIA X10 General] cashaw:
Battery BST-41

1203-8161 3 15000mAh 5.4Wh

Used it a few times to check email today, after 7 hours it is down to 88%

Using 3G, location services on, push email on.....

I do find it strange though that with similar usage each day, I still get a widely differing battery life day in, day out.....

Rebooting when recharged to 100% aways seems to give me the best results.
[XPERIA X10 General] proatiku:
guys, you need to disable 'Automatic Search' in Settings\About Phone\Software Update

it helps alot. feedback important
[XPERIA X10 General] orochiguyver:
Thanks guys.

I have things such as push email on gmail on and timescape on spaced intervals (1 or 3 hr updates for Facebook and 4hr Twitter). Location GPS was off but Ive switched it on the past few days and its made no difference to the battery (not worse or better!). Which leads me onto the following oddity I have been discovering with my X10:

With heavy usage my battery does not drain as drastically faster than expected - right now my battery is on 7%, it was full at 2.30am last night and I have used it quite heavily this afternoon when going to meet friends (6 phone calls - est total time about 25mins talk, received 35 texts today, sent about 25, browsed web for 10 mins, took three photos and used an app that streams video for 5 mins) so with all that its lasted 14 hours - so overall this is another 15hr cycle! Its so irritating!

I think I will swap mine this week for another and hope for th ebest - I hope I just have a duff battery!

Vin - how many charge cycles, how long and what (if anything) did you do for your battery to improve? How long was it lasting at the start compared to now? Thanks!

If anything changes ill post what and why (if I figure that out) :-)
[XPERIA X10 General] yoshik777:
So can all which have problem post their battery serial numbers? Maybe its the problem only with battery not with firmware?

Bst-41

1203 8161 (which i think is a code name for battery)

1007419SWNBTS 10W07

For me its still a big issue, for ppl who use it without any push mails or widgets i can only say this : its like after buying a car take out almost everything form it to make it lighter cause it uses to much fuel.... wtf.

Once again the phone went down after only 7 hours, im even to pissed off to comment it. Still havent received any answer form polish SE about it.
[XPERIA X10 General] cashaw:
That's the strange thing, I find that the more I use it, the less the battery seems to drain. I've used it a few times today and now after 10 hours the battery is still at 84%.

Yesterday I did not touch it for most of the dayand after 10 hours it was down to 58%, I used it alot in the evening and after 16 hours it was only down to 30%......

But as everyone say, it does seem to improve the more you use it.
[XPERIA X10 General] yetep:
Well 4 days after my charge & I still have 37% left of my battery..

Fairly heavy WIFI usage, 3G turned OFF when I don't need it to be (well MMS&DATA off), no auto-checks for email or facebook..

About a week after I actually got the phone i was away for 6 days, forgot the charger, and it lasted (with low usage.. 10-15 sms & 2-3 5 min calls a day) till i got home. Camera was used extensively too.

Think its great personally!
[XPERIA X10 General] yoshik777:
So can u give as numbers at your battery?

For me its impossible, even with the new/old battery form X1 which i know is working perfectly i have a drop of 10-15% per hour with ewerything turned off. Thats not how smartphone should work.
[XPERIA X10 General] yetep:
Numbers at my battery? sorry what?
[XPERIA X10 General] yoshik777:
Look at the front of Your battery ,there should be serial code for it. Just paste them here. Im curious is this short life problem only on specific series.
[XPERIA X10 General] habs101:
IF you are one of the People in here claiming that your getting 4 days

or whatever battery life

PROVIDE some PROOF because after talking with some reps taht work from sony they even state it's impossible. some that i had on my facebook, even went and deleted comments that i made about their battery life from their wall.

Either your b.s..ing or ur absolutely lucky
[XPERIA X10 General] lornova:
So, at the end I tried restoring the firmware (R1FA014) with SEUS and starting from scratch. Now I'm at 45% after 36 hours.

I started with everything disabled (email not configured, "MMS & Data" set to OFF, and so on) with the exception of the WCDMA phone network (my operator is 3G only) and the consumption was about 1% per hour. After a full night, I configured the Google account and downloaded with WiFi a couple of apps ("Battery Indicator" and "Battery Graph") then immediately disabled WiFi. Then, after some hours, I enabled "MMS & data", and the battery consumption increased a bit (to about 2-3% per hours, still very good). After a couple of hours, I also enabled GMail synchronization, and the consumption doesn't changed too much. Then I installed "Beautiful Widgets" and tomorrow I will verify the nightly consumption. Then I will go on step by step until I found what was draining so fast the battery. For the moment I suspect that reflashing the firmware impacted a lot, even if the firmware is the same. Also, now I still have Google Sync disabled. The strange thing is that, before reflashing, I had almost the same fast battery draining also in plane mode!!!

I'll keep all of you informed.
[XPERIA X10 General] proatiku:
no, am on EDGE. but i tried something earlier today, am on GSM ONLY, i disabled AUTOMATIC SEARCH for software updating, and the battery lasted longer. 50% for almost 10hours of basic use as i mentioned earlier. so am thinking, tomorrow, i will try GSM/WCDMA and see whats the difference.
[XPERIA X10 General] sungrad:
for what it is worth:

Bst-41

1203 8161

1013192SWNBTS 10W07

and i get about 15 hours on a full charge, with about 1 hour of voice calls and about 30 texts
[XPERIA X10 General] niekie:
Tonight in 6 hours 1% used, with wifi, bluetooth and 3g off. Only after forcefully ending (advanced taskkiller) the weather forecast widget. Of course I have it set to updating only manual and not to wakeup for update. Sadly the flipclock does'nt update the time if you end the yr.no weather forecast widget :mad:
[XPERIA X10 General] Astral07:
what kind of proof are you talking about? i get 2 days of normal usage, about 40h before it's drained

if not used at all, or very very little, of course it could last 4 days, especially if you turn it off over night
[XPERIA X10 General] yoshik777:
Simple some video with log form juiceploter showing last few hours.
[XPERIA X10 General] JustinL01:
Well for the first few weeks I was getting a day out of it max. I then proceded to install juice defender and a taskj killer and tried everything in this thread, made no real difference and seemed to cause more problems than it cured. I then removed both apps, rechanged the APN and just went back to using the phone normally. I turn off 3g at night and also in a bad reception area or if I have wireless enabled, ie at home or work. I am now getting 3 days of useage out of it rather than 1, for me this is more than acceptable.

The battery does drain more when I am using my bluetooth headphones for obvious reasons.

As for the people who want proof provided, who do you think you are?

Firstly why should people lie over such a trivial thing as battery life on a phone, doesn't actually achieve anything.

Secondly, Why should anyone have to provide proof, if you don't believe it fine, thats up to you, but you have no right to demand proof or anything from another forum member, I find it the height of rudeness!
[XPERIA X10 General] ShadowFlare:
I agree. Battery life in the end depends on how you use the phone and how many features of the X10 are switched off to conserve battery.
[XPERIA X10 General] cashaw:
Well I can say most honestly (scouts honour) that my phone has now been running for 28 hours, resonably heavy usage last night including playing around with GPS and Google Maps, push email, facebook updates turned on. The battery is still on 33%

It is no lie that the battery life increases as time goes on...
[XPERIA X10 General] lornova:
I'm not so sure that battery life really increases after some time, as I used also my year old X1 battery and I had the same discharge rate (about 10% per hour!). I think that there's still something obscure about the battery issue.

For me the battery has started to discharging at an acceptable rate only after a firmware download (not a new firmware version, just my firmware reinstalled). Then I carefully added software and enabled options step by step (now I'm running with 3G data always on and GMail in push mode) and I've reached 22% charge after 45 hours, although with low phone usage.
[XPERIA X10 General] yoshik777:
Yes and no. The point for me and others is to use it in normal way not with dozen things turned off to "conserve" battery. We didnt buy X10 to use just the GSM module but for all the rest, if we cant use it, it makes the phone useless. Like i said before i had a lot of different phones in the past, a alot of smartphones a lot of great SE and they didnt had any issues runnig 3G and other things.

Thats the problem with some of X10's, that they wont work properly.

Justin maybe because the net is full of lies? :P

For me its not that i dont belevie them I just need some of juice logs for my messages to SE, today i received a mail from them that this battery issue is just my problem. Yeah sure.. Especially that few of my friends who bought the phone have the same, all cant get more than 6~9 hours.

If You are getting such good time with Your phone its good for You but like i said before for me its impossible thats why im so pissed.
[XPERIA X10 General] muude:
So.. I actually sent mine in for repairs with the power usage problem. It was tested by my carrier and the found that it had a power issue - so they sent it to SE to get fixed.

It was gone for a total of 20 days.. The only reply was that they updated the software and didnt really consider it a problem. Today Im down 35% in 3½ hours.. Yeah.. No problem.. Riiiiight..
[XPERIA X10 General] lornova:
100% agree. We need to use the phone without any task killer or feature disabler for a reasonable time (at least a full day).

I don't have juice logs, but I exported battery usage with "Battery Graph" in CSV format.

Yes, I don't understand why a couple of guys are so pissed out if we have to complain with battery life. If they have such a good battery life, and they are bothered by us and don't want to help as other nice people does, they just have to ignore this thread.
[XPERIA X10 General] JustinL01:
Yoshik, anyone who bothers to lie about battery life isn't worth worrying about and they must have pretty sad lives. My point is that as far as I am concerned no one has any right to demand proof especially in the manner it has been asked, ie guilty unless you show me, sorry that is wrong regardless.

I personally couldn't give a damn if people believe me or not, as long as I know I am being true to myself and giving out factual information, people can take it or leave it. I understand respect and trust is built over time, however demanding proof is plainly ridiculous.

I am now on the 3rd day and it's down to 40%, I'll charge it tonight anyway.
[XPERIA X10 General] kiwi45:
I'm able to get 2.5 to 3 days in a single charge as well. 3G on and no tasks killer.

The battery suckers for me are location service and background sync. Except for these the rest of the settings are default out of the box.
[XPERIA X10 General] lornova:
I don't think that anyone is actually cheating on its battery times (although everywhere there's strange people, so impossible is nothing). I think instead that there are some unclear factors that causes to some good battery life, and to others a very short one.

For a lot of people the suggestions to improve battery life that have been reported in this thread either not worked or are not acceptable (e.g. the suggestion to turn off almost every function, which renders the X10 not much more than an expensive plastic brick), so someone is pissed off to hear that some other has up to 4 days of battery life.

Of course no one has the right to ask any proof to anyone, but I also think that no one has the right to say to the poor people that still has battery problem that they are the "only exception" (that one has been said to me) or to stop bothering because "smart people has already solved the issue".
[XPERIA X10 General] cashaw:
Well from my perspective, I am upto 30 hours uptime with 27% battery life remaining, I am not turning off anything in particular, 3G is on all the time, as are location services. Push mail is activated etc...etc.. (but no Bluetooth)

I don't use task killers, juice defenders or anything like that, though I did when I first bought the phone and had bad battery life for the first few weeks.

So for me I am using the phone as I want it and receive an acceptable battery life. My only tip as I have mentioned before is to reboot it when it has charged to 100%
[XPERIA X10 General] mrs3:
Try formatting SD card

I've read this in a Swiss forum, couldn't believe it but gave it a shot anyway.

Format the SD card (or justremove it, or stop the storage service).

I formatted the SD Card yesterday, switech to flight mode during the night (baut have used WLAN before without rebooting).

The battery was 100% charged when I went to bed (X10 put to sleep too :p ) and it's been still 100% this morning (more 6 hours later).

Today I lost 4% within 5 hours while 3G was active (no WLAN), Timescape set to 15 minutes updates.

Has anyone else tried this?

Michael
[XPERIA X10 General] JustinL01:
Agreed works both ways, problem is there are now thousands of these x10's that have been sold worldwide, the vocal majority on the internet are usually people who have come to complain, we just don't hear from the vast silent majority to get any significant statistic whether the battery life is considered poor. It does seem though that for a large number of people who have posted that the battery life has improved with time. I also am aware that with Android 2.1 onwards they have further improved the battery life within the OS. I still don't think you can "demand" proof. Also people like me who are now running a standard X10 with no so called battery life improvers, how are we supposed to show proof without installing these? Remembering that firstly we might not want to and secondly who is to say they don't have a detrimental impact anyway (as I found)
[XPERIA X10 General] mrs3:
AFAIK the X10 uses the same kernel as Android 2.1, and I would expect that most of the improvements regarding battery life have been made in the kernel?!?
