While in step 7, running in stock kernel, if the phone switches by itself on 9-10% and not in 0-1% what do u recommend omega???
[XPERIA X10 General] Papazian25:
I have a similar problem. My phone shuts down when my battery hits 14-15%. I can reboot it instantly and the battery says it's at 15%. If I use the phone it shuts down within 5 min again, if I leave it idle it "recovers" to around 23% in about 45min. What's wrong with my battery?
[XPERIA X10 General] chuchito1987:
Omega told me that u must reach 0% and if u know that ur phone will shut down at an specific %, then start playing a game or listen music just before it reaches the bad % to get to 0% and then u succesfully done the battery guide
[XPERIA X10 General] Papazian25:
Edit: never mind, found the answer to my question
[XPERIA X10 General] Prodigy:
I can confirm that the battery calibration app does NOT WORK (at least for me)

I was wondering why i was having pathetic battery with every ROM i try, even stock T.E.A.M

I did it this way, charged all the way to 100% and now

Whereas before when i used the app to calibrate, nothing happened, on 100%
[XPERIA X10 General] azeez77:
amazing battery life now great thread
[XPERIA X10 General] hydenobuyuki:
Is it strange that during Step 7 it stayed at 1% for a long time?

Hopefully the problems I've been having with the phone shutting down at 50-80% reported charge are just a simple calibration issue (and not something that I can't do much about like baseband issues or hardware issues)
[XPERIA X10 General] hoefkko:
I will try this, have a lot of battery issues lately
[XPERIA X10 General] OmegaRED^:
Nope.. it stayed there for very long due to the low end parameter being set to high.

By letting it properly drain you have regained that space and given more accuracy to the chargemon.

It's a good thing.

Sorry.. i haven't been around much i have a job that requires me to be on standby all the time... at-least the pay is good.
[XPERIA X10 General] kabidin:
i have two batteries. so i need to save each bin files "data/system/batterystats.bin" when using the battery respectively. is that right?
[XPERIA X10 General] OmegaRED^:
Yes you will have to.

I was working on a simple app that would do this for you but time makes fools of us all.
[XPERIA X10 General] kabidin:
ok..i'm enjoying the batt life now:) thanks
[XPERIA X10 General] kungfu0210:
Thanks for this guide. I've done this calibration twice now, once on wolf's rom and now on FXP CM7.

In both cases I thought the rom was bad for battery but then did this battery optimisation & it sorted it.

My battery life increases exponentially after doing this. Thanks again for a great post :-)

[XPERIA X10 General] xuhaib:
i m at step 7

and my battery charging is stuck at 87.... still charging but not moving above 87. and indicater lite is not green yet. now i have to remove the charger plug or should wait for indicater to turn green...

and how many cycle will require to get the charging back to 100 from 87
[XPERIA X10 General] unroot:
my phone battery is stuck at 51%... how many cycles will it take for me to reach at 100%..

also it only happened after installing MIUI by whitecookie earlier it was charging fully to 100%.

Should I directly use calibration APP or follow this method?
[XPERIA X10 General] lythanhlong:
I am going to buy myself a mugen battery.

Link: http://www.mugen-power-batteries.co...xperia-x1-1800mah-extra-eros-akkumulator.html

When I got it and I put it in, would I have to do these steps? Or is the battery already optimized?

Another topic: This is what I did. I full discharged phone till there wasn't any power what so ever. Then I charged it for 4+ hrs so it reaches 100%. I then wiped battery stats to get default. Then I used this method: http://xdaforums.com/showthread.php?t=943626&highlight=battery. If I did your method after that, would it be ever better? Since the method before this is bout battery stats and yours is bout the top and lower things. Would this work? Combining these two methods together.
[XPERIA X10 General] AX10i:
Is there any problem if you follow these steps without wiping the battery stats?

And can't an optimized batterystats.bin be uploaded and used in several X10s?
[XPERIA X10 General] OmegaRED^:
No because some developers think they are smart and use different or modified versions of charge-mon.

Both methods are the same.

Mine just has a few more details.

The mugen battery has a different current rating and therefore must be re-optimized.

Holy CRAP kids!

I said many times that app is a piece of junk and does not correctly support the x10.
[XPERIA X10 General] AX10i:
You realize that I didn't understand the terminology, don't you?
[XPERIA X10 General] OmegaRED^:
The software that determines the current battery load and charge.. some times some developers forget to keep it "unified" different "Charge Monitor" in some roms.

Some roms have incompatible charge monitor parameters and that's why the battery calibrator app many times causes more problems by setting up incompatible value's for the battery stats file there by causing bad optimization.

Then there is the "+- mA" factor to take in hand.

Some batteries have slightly different ratings in current and voltage, there for each battery has tiny differences in charge characteristics although battery manufacturers do the best to match and make cells as similar as possible.

Manually optimized battery stats will always be way more accurate than any default setting.

I have used similar rules for all my Ni-CD, N-MH & Li-Ion batteries over the years in all my phones and most of my portable devices including my PSP.

The concept stays the same.

1. fully load and unload cells

2. never leave batteries empty

And i can safely say have never had a battery go inert on me from following my advice..
[XPERIA X10 General] rellish:
Thanks for the guide, really improved my battery life!
[XPERIA X10 General] NothingCtrl:
Thanks, I feel my X10 now have better battery :D
[XPERIA X10 General] NMaverick:
Hi guys,

I have two batteries... I decided to use the first for 3 months and every 3 months to change to my other battery. The first one is Sony original 1500 MAh battery. The other is a chinese 2600 MAh battery (performing quite well I might add!!). The thing is that the statistics get mixed up and I must erase battery stats from XRecovery on every change. Will this also affect the countdown of the capacity down to 0? I have noticed some strange peaks during hours I am not using the phone. I am using VMOd 5.1 ROM with latset 5a doomkernel.
[XPERIA X10 General] sarathvenmony:
thx for ur steps ....
[XPERIA X10 General] NMaverick:
Does anyone have the same or similar problem?
[XPERIA X10 General] wendac:
tried but did not work...maybe buy a super battery charger is better option (I got one with 4800mA and its size is very small)
[XPERIA X10 General] lythanhlong:
Just received my mugen 1800 battery. Are the steps exactly the same?

---------- Post added at 05:13 PM ---------- Previous post was at 04:56 PM ----------

So basically, in the end, it's going to be the same?
[XPERIA X10 General] OmegaRED^:
The same procedure to optimize will work perfectly.

You will have better results with higher mA cells.
[XPERIA X10 General] lythanhlong:
Sweet thanks. (:
[XPERIA X10 General] keyed911:
your post is detailed than the one that I have read, I will try this
[XPERIA X10 General] chechotoro:
Hello,

I did the all procedure but my phone continue shut off even with 50% of charge.

I thought that was a problem with the roms, but I´ve been testing a few, but nothing changes, even with the SE stock rom.

I bought a new battery and waiting to test.

Anything else to do?
[XPERIA X10 General] chikencito12:
Thanks its true
[XPERIA X10 General] cybaster89:
will follow your step to make my battery goes normal ...
[XPERIA X10 General] sathurnn:
Will help us an apk called "CurrentWidget"?

When the phone is charging, it shows the current mA sold by the charger

When the charge reaches 100% this value is 0

My batt wasn't optimized, so I have follow your guide, and I noticed that when I applied step 1-5, first time even if the batt was at 100%, currentwidget showed that it wasn't true because the charger kept to sold mA to the phone.

After applying step 1-5 three times, when the batt reaches 100% currentwidget shows 0 mA sold.

I hope I was clear...excuse for my english!

[XPERIA X10 General] Erik89:
I experience exactly the same. When I drop below 50%, the phone shut-off every time.
[XPERIA X10 General] chechotoro:
Have you found out any solution?
[XPERIA X10 General] OmegaRED^:
Sounds like a issue with the battery stats.

Try deleting the stats file and let me know if that helps.

Ahhh... nice it lets you see the charging current.

But no.. won't really help. thanks for thinking anyway.
[XPERIA X10 General] Erik89:
I allready did.

Flashed the ROM again and then wipe the battery stats.
[XPERIA X10 General] sathurnn:
By the way my x10 shut down when batt reaches 15%.

I followed your guide twice and also deleted battstats.bin

I think it's time to replace it!!:D
[XPERIA X10 General] OmegaRED^:
Added To OP.

This leads to the final part of my guide.

Damaged batteries.

If your life on the battery when using only airplane mode.

Is very bad.

Then you should be careful.

1. Check for any swelling or deformation on the battery.

2. Battery gets very warm while charging on standby in airplane mode.

3. Battery is just not lasting after calibration even in in airplane mode.

If found, replace with new battery.

Perform calibration "i.e. my guide"

This should also be done before beginning my guide.

Enjoy

This method seems to have cached on in a few other cell forums as well.

and sparked one or two debates on XDA.
[XPERIA X10 General] Erik89:
I checked it all before.. So my battery is almost dead?

With 3g, some sync of google when on standby the phone is turning off in 2,5 hour.

When I use the phone its less a hour.

Actually...its 49% when the phone turnes off.

Every time I start the phone again.. it shuts itself off whitin 1 minute.

When I'm lucky I can make a phonecall till someone hangs up.
[XPERIA X10 General] OmegaRED^:
It's very possible the cell has started to become inert.

Question: is it getting worse with each 'normal' charge?

It could be the V- level is giving issue's or it built up a memory.
[XPERIA X10 General] Erik89:
I think it stays the same not worser definitively...

Is it better to boot the phone every time till its really 0% or load again after a shutdown?

The last days I loaded straight after the first shutdown.
[XPERIA X10 General] Tof37:
Had this problem once... I just turned on the phone until it reached 0%( had to turn it on several times because the phone shut down itself). When the batt reached 0% and turned off, just plugged it offline and let it fully charge. Now it shut down at 0%...

Hope it helps ...
[XPERIA X10 General] Erik89:
I'l try it tomorrow my battery is now 100%.. My solution on the moment is a Duracell travel charger (accu inside) works very good.

Thanks for sharing
[XPERIA X10 General] furyd:
Firstly, thanks for the detailed Guide and subsequent replies.. all very interesting reading.

Will try on my x10, although the battery is pretty good (1.5 days w/wifi/sync on etc.)

Just one question, I'm hoping someone can enlighten me.. Can the same method be applied to an x10 mini pro?? I need to calibrate my wife's phone as it drops from 100% to 30% within about 5 hours with very basic use..?

Looking forward to your input.. cheers! :D
[XPERIA X10 General] Erik89:
My battery is still 'broken'. I think its time to buy a new one before my phone ends flying out of the window. Its very frustrating if nothing will work.

Thanks for the help guys +1
[XPERIA X10 General] unburleyvable:
Thanks, I'll be trying this!

A quick question on the subject of charging... has anyone noticed a more "full" charge by charging through USB (slower) rather than plugging into the wall (fast) ?
[XPERIA X10 General] djvirus1:
thanks. always had a problem of battery after using wolf's rom
[XPERIA X10 General] kungfu0210:
This battery optimisation method is great, i've used it a few times after my battery starts to have short charge after flashing a load of different roms. Every time this method works and gets me back to full battery useage.

Please make this topic a sticky to save me the few seconds it takes to search for it ;)
[XPERIA X10 General] OmegaRED^:
I want a few of you having this problem to try this.

When your battery gets low like 2% to 5% switch on airplane mode on and leave the phone to slowly drain away.
[XPERIA X10 General] danijel021:
I have a big problem with charging I tried everything, Calibrations battery, this method new room,new battery.....

Phone very slowly charging 50% to 8 + hours and then for 1% he needs 1 hour.

I installed "Battery Monitor Widget" to see how much power it is drawing and found that AC power draws only about 350+mA and sometimes it is as low as 3mA!

what is happening?
[XPERIA X10 General] OmegaRED^:
Try cleaning the contact points on the phone & battery.

OR

Check what apps you have running in the background.

Disable all radio's, Bluetooth, WI-FI, GSM, ect.

Hi there.

Well it seems you are having severe issue's.

I think it may be.

1. bad battery.

2. issue's with the chargemon settings. "wipe battery stats from xrecovery"

but nothing, still very slow to charge!

I noticed that the battery is not charging when phone is switched off!!!(this was before my procedure and the same is now)

solutions?
[XPERIA X10 General] OmegaRED^:
1. Check your cable.

2. Try to find a different charger "x10 mini pro charger is epic" or cable.. i had a issue where one cable was doing this.

3. Replace battery.

[XPERIA X10 General] donnolasco:
Thanks for the guide! It works well for me. I have been talking on the phone for 30 mins, and from 100%, it's only down to 95%.
[XPERIA X10 General] kenectd:
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...

The battery may get stuck at 70% to 99% "most of the time 88%"

The cells have now reached full potential

IF in the case that it keeps charging after the 4th time your battery is fully optimized Enjoy, Continue with step 7

So i'm on my 4th time of repetition, my battery was on 88% after i re-inserted and it's charging normally, does that mean i should continue to step 7 after i reaches 100%? And is this calibration permanent?

My english is kinda bad can you explain better step 7 and 8? And what did you mean dont leave the battery? Btw i tried to delete the batterystats once it reached 100% but i didnt see improvements and another question does flashing the undervolting thingy will help?
[XPERIA X10 General] shahkam:
What i did is the following charged phone t0 100% then :

I powered it off , tooken battery out,plugged in charger, battery,booted it up and i saw that grey battery icon whit a little thunder icon meaning its charged i repeated the same process and i booted up and saw i had 87% it directly went to 88 then i left on standby and it reached 92% and now i dont known if my battery life is better because i usually listen to music on my way to work and its like 1h30 trip and i end up from home fully charged to work whit only 70% will post feedback tomorrow and till now i didnt let my phone die because im going to sleep and need it to charge for tomorrow lol
[XPERIA X10 General] OmegaRED^:
One the battery is empty and the phone switches off.

Charge it right away, don't wait.

"it's not healthy for a battery to stay empty"

It works for standby only and it may not work on certain basebands or roms.

Should be fine.

Continue with step 7

I am using CM7 j20 k008 gingerbread ROM and the battery drain drains very fast. Is there is any way to fix it? Thanks
[XPERIA X10 General] OmegaRED^:
WRONG THREAD.

In your case..

If you tried this and it did not work.

You are having a baseband malfunction.

After installing the phone may crash a couple times.

Re-Flash the Baseband or ROM.

Or you can try.

Dev Tools > Bad behaviour > Crash System Server and wait for reboot.
[XPERIA X10 General] shahkam:
Is it okay if I listen to music or browse the net or xda to drain battery or I really need to leave it on standby?
[XPERIA X10 General] OmegaRED^:
Yeah it should be fine.. but a slow drain is better.

Using step 7 with the undervolt will take forever.

Just make sure you run it down all the way.
[XPERIA X10 General] AyDee:
I used the battery calibration app (charged to 100, wipe stats, discharge) and I don't see a difference.

[XPERIA X10 General] shahkam:
Oh darn had some more questions for you oh well I don't se an improvement whit this I feel its worse since step 7 and last nighti interrupted the charging process for a minute and the battery was already in the green zone I let it charge to 100% then turned it off this.morning I booted up whit 97% why is that so?
[XPERIA X10 General] OmegaRED^:
I have a few MB's left.

It should not be giving any issue's if you interrupted the phone for a few minutes.

That means your battery was already fine and did not require to be optimized.

If you say it's worse... how much worse? like 10 seconds or 10 hours?
[XPERIA X10 General] shahkam:
Well not extremly worse but I can feel like its slightly draining faster but not sure if its me and anyways I need to.let it drain a couple of times hope this will be fixed next time :)
[XPERIA X10 General] OmegaRED^:
This is why it's important to do it exactly like i said from start to finish if you want the battery to be perfect.

Hi OmegaRed, thank you for this guide, i have a question. When i try to set the "top" level of the phone (following your steps exactly) I seem to always hit 100% (5 tries of steps 1-4).

Obviously i don't want to damage the phone or battery, but it seems i have not reached a point where it charges to less than 100%. So - should i try more times?

My second question is about step 4/5. When i put to battery back in the phone it powers on but only to the "charging" battery screen, so i am not sure how you mean to "keep an eye on it", should i power it on at this point?

I have tried leaving it at the charging screen and powering on - in my 5 attempts at steps 1-4/5 either way it still goes to 100%.

If i have missed something i apologise in advance!!!

Edit: always turns on at the 88% mark (indicative of cache wipe i assume??) following re-insert of battery
