If it has reset to 88% and rises that means the battery is not at full capacity.

As the battery voltage is still rising.

That could be 1 of 3 things.

1. your battery is in a bad state.

2. your charge monitor is different.

3. app is effecting your results.

You can repeat this many times "you only need to stress if the battery gets hot"

And it should not as it has over-current protection.

If it rises to 100% very fast this may be a indication that it is full capability.

But i have yet to see this happen.

A few more edits to the OP. "to correctly further clarify things.
[XPERIA X10 General] baz@gmx.co.uk:
Thanks Omega, great avatar btw;-)

Did seem to charge quicker the last 2 times so maybe that's it!
[XPERIA X10 General] drmdrago:
I think so... :)
[XPERIA X10 General] OmegaRED^:
happy 2 help. :)
[XPERIA X10 General] AyDee:
Yes, mine seemed faster the last time too. Went to 89% immediately, the rest was faster than normal but not 'super fast'.

I had previously tried charging to 100% then reset batt stats and discharging fully before trying this so maybe that had an effect.
[XPERIA X10 General] Neo.:
I have read your guide and I'm having a couple of questions.

Everything from 1-6 seems alright but in step 7. Don't Li-on Batters prefer to be charged rather than drained? (I heard it reduces the life cycle of the battery)

Please clarify because I'm having doubts on draining the battery
[XPERIA X10 General] OmegaRED^:
Only if you leave them empty.;)

The damage happens when it gets discharged and left empty for long periods.

This is not found online.. i have experience to back that up.
[XPERIA X10 General] gregbradley:
Hi.

Many thanks for the help with the xrecovery method, I now get the battery to drop to 88% when I reinsert the battery and plug back in...

The only issue is, I have been doing this for about 2 days and whenever i do this step it always charges back up to 100% from 88%...

"6. Repeat steps 1 to 5

Repeat this no more than 2 to 5 times

till the battery will not charge further

A few extra may be required...

70% to 90% "most of the time 88%"

The cells have now reached full potential"

Does this mean that there is still capacity for charge in the battery?

"If it has reset to 88% and rises that means the battery is not at full capacity.

As the battery voltage is still rising"

I check the tempreture....it never gets hot and takes a similar amount of time to get back to 100%.

I was getting about 30-36 hours out of the battery with "normal" use.

?

Many thanks
[XPERIA X10 General] OmegaRED^:
:edit sorry.

You battery is then optimized.

No further requirement for this guide for you
[XPERIA X10 General] gregbradley:
Whoopeeee!!!!!!!!!!!!

Many thanks...:)
[XPERIA X10 General] OmegaRED^:
If you get this kind of behavior then doing it more than 4 times is useless.

This is a bug in the charge monitor.

But now you can be rest assured that it's optimized.

How much time did it take to get back to 100% from 88% on the last charge?
[XPERIA X10 General] gregbradley:
Again..

many thanks....

I have just stopped charging at 100%

I will let you know how long i get...

:)
[XPERIA X10 General] Tjotte:
43h with 17% still in battery, with a Little less then regular use for Me,. I'm on trips arc 0.5 rom.

At about 47h though my phone shut itself down even though it said 7% battery left, tried restarting it

and again it auto switch off despite battery saying 7%... whats up with that?
[XPERIA X10 General] OmegaRED^:
Depends on where the app or widget or system readout got that from.

That means at 7% the hardware was reading a much lower value off the battery than the software was reporting.

It's no big issue. Most of the time software tries to predict the value while discharging using the current voltage level and the current mA drain. errors can occur.
[XPERIA X10 General] Neo.:
One more question.Don't we have to wipe battery status? ??
[XPERIA X10 General] OmegaRED^:
No.. not really.

Only if you have severe problems or bugs.

But wiping does bring it back to the defaults.

I added that as a guideline "thanx" for reminding me.

The mind is getting old now.
[XPERIA X10 General] bentoKG:
this one is ultimate lol
[XPERIA X10 General] gregbradley:
This is what you can expect after following this guide. I also use the undervolt module but I am really impressed with this.
[XPERIA X10 General] KInG GaME:
custom kernal 10 gives that prob switch back to stock
[XPERIA X10 General] Artest113:
how often should we perform battery calibration?
[XPERIA X10 General] alevin28:
wow!! my battery life went from only 10 hours to almost 21, unbelievable man!! thanks!!!! (all at medium to heavy usage)
[XPERIA X10 General] OmegaRED^:
Only once.

And if you re-flash to a new kernel or rom.

"working on a way to backup the battery cache currently."

This way you can save your optimized battery file and restore after flashing a new rom.

I'm happy this is helping many of you.

Thx nice one Omega ^^

[XPERIA X10 General] estugarda:
I just went though all the steps exactly as described. It took 6 times of removing the battery and charging it from 88% to finally stop at 96% at the 6th attempt. After that I discharged it slowly until the phone turned off. I charged it, and it went directly to 100%. I though it means it's optimized. But I actually see no improvement. Just like before I get:

- Approx 24hrs of use with all wireless turned off, brightness low, including MMS and data, and only 2 3min phone calls; the majority of battery is wasted by cellular standby 47%, then phone idle 36%, 12% Android System, 5% Phone calls

- Any data/wireless/multimedia will get it well below 20hrs. For instance, I charged it last night to 100%, plugged it off, killed all running apps with ATM, but forgot to turn of wifi. After 6-7 hours of sleep battery was 69%.

There is no improvement. I even have a feeling it might be slightly worse after this modification, but I am not sure. I have to test it a bit more.

I bought the new x10 like 2 weeks ago. So it has probably some 12-14 charging cycles.

In my opinion it is very, very poor battery life in general on X10. My GF has a year old HTC Desire, and with WiFi turned on all the time, and email check every 5 min it stays on for 2-3 days regularly. Only extremely heavy multimedia/surfing along with wifi, will discharge it in 24hrs.

Hopefully the 2.3 update will bring us better battery life. What do you think?
[XPERIA X10 General] OmegaRED^:
It may be your rom.. it may be something else.

The guide works.

The only thing it cannot account for is a bad chipset, baseband issue's and random software bugs.

So your post does not apply

It should not be worse. if it is something went wrong along the way.

And you did this out of your own choice as my first post says.

It's not my problem if anything goes wrong.

Also 24 hours is average.

If it did not see a change that means there may have been nothing wrong to start with.
[XPERIA X10 General] estugarda:
No, no. I din't want to say you are responsible for anything. It's clear that we do everything on our own choice here. I appreciate your contribution.

I'm not even sure it really is worse than before. These things can vary and be very subjective. It definitely isn't better in my case. I think this part of the post does apply.

I'm using the official v2.1 ROM with latest updates. Rooted.

Actually, if my x10 would hold 24hrs with wifi on, with some multimedia use, messaging and few phone calls, I'd be satisfied. But unfortunately, when I use it like that, it doesn't hold for a day. Not even close. And just to be clear, I hold SE and Android OS responsible. Not the author of the thread.
[XPERIA X10 General] OmegaRED^:
I'm sorry.

But 24 hours on stock is very good.
[XPERIA X10 General] estugarda:
Oh!? I didn't expect that. 24h would be OK for me with wifi, data, minimum of multimedia and few phone calls. But this way X10 is below my standards then. On the other hand it's definitely possible for Android smartphones to go for 2-3 days with normal use.

Since you say that 24hrs is normal on stock ROM for minimal use, does that imply that you think it would be better with some custom ROM? Do you have anything specific in mind?

Also, what do you think; will the official 2.3 update increase the battery life?
[XPERIA X10 General] OmegaRED^:
Wolfbreaks CM3.16 of course.

He's close to releasing a new one.
[XPERIA X10 General] astrall:
I need a help here.

My battery won't fully charged. When I charged it, it stuck on 93% and discharge itself. Any help?
[XPERIA X10 General] OmegaRED^:
Did you read the guide?

If it got stuck at 93% it means that it has reached the top point of the battery.

Continue with step 7
[XPERIA X10 General] astrall:
Sorry, but I'm a bit confused. Yeah I've read the whole guide. I thought it's a MUST that the battery should be 100% before discharging. I'm wrong, right?

So does that mean, I can't charge upto 100% when done callibrating?
[XPERIA X10 General] OmegaRED^:
STEP 6

Continue with step 7
[XPERIA X10 General] astrall:
Ok. Ok. I'll just keep going now. :)

Sorry for repeated queries. :D

cheers,

A
[XPERIA X10 General] Delorvallois:
Hello,

I respected this then I turned on the phone. It showed an empty battery and start charging it from 0%...

I didn't expected that, is it normal ? I understood that it should now start from 88% or around to a max value under 100%.
[XPERIA X10 General] OmegaRED^:
1. What phone are you using?

2. Are you using any mods, roms or modifications?

Charging from 0% is not a huge issue.

Also the phone should have turned itself on.
[XPERIA X10 General] Delorvallois:
Fast answer, thx :)

Xperia X10 using Wolf CM 6.1.3 on .54 baseband.

Also my phone never turned on itself...It just charge off, and I always have to turn it on manualy. By the way, most of the time, I charge it on, not off.

It's charging very fast (95% now from USB). 0% was just befor my first post.
[XPERIA X10 General] OmegaRED^:
I don't think in your case it will be needed to do this more than once.

No problem, good luck.
[XPERIA X10 General] Delorvallois:
FYI :

It seems it's not charging over 97%, I'll not repeat the first steps as suggested.

Continuing to the long road of step 6 and further.

I'll update my experience if needed.

Thx again o7
[XPERIA X10 General] astrall:
@OmegaRed

I continue step 7 and on my next cycle it starts discharging at 64%. Is it normal?
[XPERIA X10 General] OmegaRED^:
NO.. wtf are you talking about.

This makes no sense.

How would it start discharging at 64% unless you discharge it at that point.

I think your charge monitor is screwed up.

:edit try wiping your battery stats using xrecovery.
[XPERIA X10 General] astrall:
Yeah that's my point at the first place.

First when I charge it, it stop at 94%. Then you said continue, so I discharge it until the phone dies (not aggressively discharge.)

Then while charging it I notice that it stop at 64% then discharge at 63%.

I manually deleted the batterystat.bin now and discharge it again and do an offline charging and we'll see how it goes. :)
[XPERIA X10 General] ili_colonel_kurtz_ili:
Does this indicate anything ?

Hi,

I am asking this question here as the originator of the thread has good experience with LiPo batts.

The attached image shows spikes in current (power in watts also shows an exact correspondence with the current spikes in another graph in this app)

The available battery also reduces by 1% with each such spike as seen in the image.

I was wondering if this is ideally how the available battery discharge graph plots against current/power usage. :rolleyes: :confused:

In such a situation, should your guide help increasing the battery life ?

Also, my battery at times has reached temp of 45-47 degrees while charging. could this be a calibration issue or the monitor app issue ? or is it a hardware issue (battery or chipset :confused:)

My Device:

SE Xperia X10i

Stock Rom 2.1

Firmware: 2.1.A.0.435

BaseBand: 2.1.54
[XPERIA X10 General] OmegaRED^:
This my friend is a baseband and charge monitor issue.

The spikes are charge mon related.

The heat is the radio suffering to get signal on the incorrect band.

Do you have low signal in your area?
[XPERIA X10 General] ili_colonel_kurtz_ili:
No, there is no signal issue in my area. infact the signal is very very good :D
[XPERIA X10 General] OmegaRED^:
Then it's possible you have a bad chipset and the baseband is giving issue's
[XPERIA X10 General] ili_colonel_kurtz_ili:
yeah looks like it to me as well ...

is there any other possibility ?
[XPERIA X10 General] OmegaRED^:
I have no idea. i'm not much of a android developer.

I can only help thru basic trouble shooting and observation.

Good luck buddy.
[XPERIA X10 General] ili_colonel_kurtz_ili:
No Issues at all ...

Thanks for your comments brother :D
[XPERIA X10 General] unk027:
i try this x)
[XPERIA X10 General] surrealillusion:
Here is my personal experience with this method so far over the last 24 hrs. I started following the guide yesterday and repeated steps 1-5 (each time the battery would start from 88% and go back up to 100%). I started letting the battery drain last night but concerned that my battery would die while I would be out all day due to the power consumption (70% after 10 hrs of being unplugged) I plugged it back and decided to repeat the steps (battery has been a constant temp when following this procedure).

Alas I fell asleep last night with the phone still plugged in and restarted the process this morning. To my surprise/shock the battery is now showing it's in the red when cycling through steps 1-5. I pulled it out after a while and tried again and got the same red led when dropping the battery in a second time. Is there something potentially wrong with my battery now?

Oh forgot to add my battery stats info from the SE menu while I watch it charge up:

Battery health: Good

Battery Voltage: 4210 mV

Battery Temperature: 33c
[XPERIA X10 General] maikinho10:
Hello OmegaRED,

i have one question.

In every 2.2rom (Trips or Wolfs) my handy is shutdown between 35-37%, quite suddenly the Battery monitor shows the battery is empty :confused:

why is this? Is my battery damaged? I have used the App Battery Calibration but the same i have used your way here but always shutdown:(

Greets and Thanks for your answer!
[XPERIA X10 General] OmegaRED^:
That is strange, there has been issue's reported with the battery being left in the unit while charging overnight.

As far a i know the battery should not have any.

Wipe battery stats! from xRecovery

I don't know why..

but the battery calibration app is causing alot of crap with the x10 charge mon parameters.

It has set the low point way too high for your battery.

Wipe battery stats! from xRecovery
[XPERIA X10 General] maikinho10:
if i change a rom, i wipe always the battery stats from xrecovery. have you an other idea?

i´m alone with this issue?

greets
[XPERIA X10 General] OmegaRED^:
I don't know if your chargemon is screwing up.

If you used the battery calibration app then the stats got messed up by that.

It may be you have a bad battery.

There could be many reason for your issue's.
[XPERIA X10 General] yugiyao:
nice info/guide will gv it a try soon

Thx man :>
[XPERIA X10 General] totoboy7:
Hey OmegaRED, thanks for the guide.. It helped a lot!:D
[XPERIA X10 General] estugarda:
Well, I assume you meant Wolfbreaks CM_6.1.3_[v006] ROM. I installed it few days ago (i know there is a newer one). I still don't see any battery life improvement on this one. I get 24 hrs max on very light use.

I noticed one thing though. When on Airplane mode, the battery life increases immensely. For instance, if I don't put the phone in Airplane mode during the night, it drops from 100% to 80% in 6 hrs. If I turn on the Airplane Mode it drops to only 98% in 6 hrs.

Of course I know it is something to be expected, but since it is such a big difference, I can't help but think that there is some kind of a battery leak in cell standby or something.

Any ideas on this?

PS Should I wipe the battery stats after I ran this (your) guide, once I installed the new ROM?
[XPERIA X10 General] OmegaRED^:
It's the GSM radio.

It eats thru battery like a fat child.

Wipe stats after installing rom then do this guide.
[XPERIA X10 General] estugarda:
So it's the GSM radio afterall! Looks like this is the problematic part on my X10. I had the feeling something is not right. Maybe those people who get 2 days on x10 have different hardware!?

This is probably also what differentiates X10 from other smartphones in it's class. There is no other reason why would the difference be so noticeable. For instance similarly used HTC Desire will go for 2-3 days, and x10 less than a day. And Desire has actually a smaller battery. Also when Airplane is turned on on Desire, it doesn't improve the battery so much as on x10.

There must be something very wrong with GSM radio on x10. I wonder if it is something that can be fixed by software?

Thanks. I'll try it.
[XPERIA X10 General] OmegaRED^:
Look with BB.67 it's been a bit more bearable for me.

But it's still pathetic.

The phone never does what it's supposed to on paper.

And i clearly think it's a software issue that SE just will not fix.

It's easier to force us to upgrade.
[XPERIA X10 General] estugarda:
Yeah. We'll upgrade to HTC.

And then we hopefully won't have to waste time on tweaks that should've been done by the manufacturer.

Thanks for BB advice. I'll give it a try.

EDIT: BB 67 didn't help. 24hrs just as before.

X10 is definitely my last SE. And I had nothing but Sony or SE since 2000.
[XPERIA X10 General] surrealillusion:
After running through the guide the average time my battery would last would be about 24 hrs (GSM PRL auto, background sync on, wifi and bt off, and not a lot of usage at all). Then I started noticing the phone would shut off while in my pocket. Boot it back up and everything appears to be fine. Then while using Facebook yesterday it shut off right in the middle of a refresh.

Phone just went out of warranty with SE but I figured since I bought it with a CC that gives me an extra year warranty I'd just ask them to quote me the repair costs. This is where things go south. SE rep asks me the usual TS questions (tried updating using SEUS, tried PC companion, try a different charger and battery, etc). Then when I mention my phone is unlocked I'm pretty sure I heard her say that's illegal and voids the warranty. I lost it. It may not be what the carrier want us to do but it is certainly not illegal (as an end user we have the right to choose who our provider is what what phones we use). In many other countries it's fine to have your carrier unlock the phone, but since Rogers likes to run a monopoly and not give out NCK codes even though users pay the full price we get a short end of the stick.

This being said though I could care less if it voids the warranty because I've sent handsets back to the SE repair centre before that have been unlocked and they've come back fixed. I didn't appreciate her just flat out telling me that it's pointless to do so. This sadly isn't the first time I've had frustrations dealing with SE and this may very well be my last SE phone (I started using an iPad2 and two months in I haven't had any major gripes about it).

Oh and the original reason for the post before I got sidetracked, battery life. Ordered a replacement battery from gocellular.ca and tossed it in after my call with SE. Battery showed with about 56% life (around 9 PM and it currently shows 29% with being on for 12 hrs. I won't know until a few optimization cycles, but it may seem my old battery had some bad cells.
[XPERIA X10 General] acceleratum:
Thanks, im gonna try it ou definitely, the mini pro is an excelent phone but the battery is really bad, gotta squeeze everything possible

:-)
[XPERIA X10 General] surrealillusion:
After running in the new battery for the past couple of days on average I am see 30 hrs or so before I go ahead and plug it in for a charge. Background data on, sync, wifi, bt, gps, off. A few calls and a few txt msgs. We'll see how the battery does while I'm travelling for work next week but I'm happier with the new battery's performance so far.
[XPERIA X10 General] walr:
optimizing multiple batteries

Hi there, does anyone knows how android will behave when optimizing different batteries? I have the 1500 original, a 1800 and a 3600 mugen power. I never use all the three, but at least twice a year i travel to place where there is not electricity... and in my next trip I want to record a 4 day trek with the phone gps. So I`m looking into any methods to maximize my batteries.
[XPERIA X10 General] OmegaRED^:
You will have to optimize each battery separately.

Fully charge them and the save the stats file using root explorer for each battery.
[XPERIA X10 General] walr:
Thanks man, somehow I ended up trying this the same night, but I can`t figure out why it doesn't give me permission to copy and paste the battery file, even though all is apparently right. Anyway... I`ll just clean the battery stats file when I change batteries since I`ll only use all of them on a few situations. I`ll see how it works and post here.

Thanks again =)
[XPERIA X10 General] prince_huggy:
Question on the OP

Does the OP work in reverse? :confused:

i.e if I let the battery completely drain a few times and then do the charging and disconnecting of battery.
[XPERIA X10 General] OmegaRED^:
Did you read the first post? follow the instructions as is.. do not deviate.
[XPERIA X10 General] Androidius:
I've repeated steps 1-5 5 or 6 times already, but it still keeps charging. Won't I grill my phone?:confused:
[XPERIA X10 General] OmegaRED^:
I said no more than 5 times.

This sometimes happens.

Continue with step 7.
[XPERIA X10 General] tawcw:
2 months ago,i tried and it worked.

i tried again again(more than 15 times),but the battery still 89%.:confused:

i'll continue step 7 ,hope this method is effective
[XPERIA X10 General] lerkin:
Hi, I have a question here...

Where I should read 88% after 4 step, the phone have been turned off after 2 step?

Sorry, I just noticed it's a X10 thread!

I have lg optimus one
[XPERIA X10 General] rakesh_485:
Same here..

Why... why.... :(
[XPERIA X10 General] teddymild:
Hi red I'm on step 7 after 34 hours since last charge, now battery read 1% current 3515 mv. Is it normal? I read somewhere low range should be around 3400. Should I do something else? Thanks

my phone has set a record today. 14 hours with constant internet connection:)

oh, not yet. still 1% remaining:D
[XPERIA X10 General] prince_huggy:
Thank you.:D

I was only asking because I have let my battery die a few times in the past and now I've done steps 1 - 5.
[XPERIA X10 General] OmegaRED^:
should be fine.. :)

i haven't looked at the lowest possible voltages yet.
[XPERIA X10 General] shahkam:
I tried this trick many times and i never get an beyter battery life right now mines just suck so bad i tried all the methods possible and i can see the battery draon right in front of my eyes in 1hour i loose like 15% when i do like medium usage sync off 3g off background data off all that and i once managed to get an epic battery life by reflashing baseband .67 then flashing stock rom and then wolfbreak rom but since then i never managed to get it right any clue why ?
[XPERIA X10 General] OmegaRED^:
it may be due to the new chargemon.. i'm not sure.

It may be that your BB is not settling.

it can sometimes take up to a week.
[XPERIA X10 General] shahkam:
oh should i reflash the baseband and then let it discharge and charge back to 100% and delete batterystats that bin do you think it will help ?
[XPERIA X10 General] OmegaRED^:
Just delete the battery stats.
[XPERIA X10 General] shahkam:
lets hope its gonna work out thanks for replying fast your awesome hehe battery reached 100% it was in charge deleted stats gonna drain whitout any break and charge again :)
