A while back there was a thread about supposedly calibrating X10's battery by charging it to 100%, turning it off, taking the battery out and inserting the charger chord, and then putting the battery back. This made the battery percentage drop down to 88% and when repeating this procedure a couple of times it would rise back to 100%, thus supposedly calibrating the battery. This worked to some and to others not. Now that we have xRecovery, I thought I'd try this in conjuction with the battery stats wipe option and whaddayaknow, I've got better battery life now. Now I can go through a whole day with heavy usage and still have some battery left for the phone to survive through night with data and syncing on. So I thought I'd share this with you guys to try out and report too.
ROOT IS REQUIRED!
STEPS:
1. Download and install xRecovery from here.
2. Charge your phone to 100%
3. Turn off the phone and boot into recovery
4. In recovery, go to Advanced options --> Wipe Battery Stats --> Yes
5. Take the battery off
6. Insert the charger chord
7. Put the battery back and wait for the phone to boot
8. Once the phone boots up, you will notice that the battery percentage is around 88% instead of 100%
9. Charge the phone back to 100%
10. Repeat 4-5 times, seems to be the sweet spot
11. Enjoy your hopefully better battery life and report!
REMEMBER THAT I'M NOT RESPONSIBLE IF YOUR PHONE BLOWS UP ETC. AFTER THIS!
Do i need to repeat all from 1 to 10 until i get 100? And do i need to do this 1 Time or do i need to do this the next 2-3 Days too?

Repeat from step 2 onwards till step 9. I believe you don't have to do it more than two or three times to get the desired effect, that's why I'd like to have you guys to test it out too to confirm.
Been through the cycle 5 times, still showing 87% at reboot.
Just for the record, I have the 435 firmware.

Did you recharge after reboot?

Yes my friend, followed to the letter.
I have noticed one thing, my battery is behaving a bit strange. I used it earlier and it depleted from 100 to 93%, it then went back in my pocket for an hour or so and when I next used it it said 98% charge.
I ran it down to 83% and then put it back to sleep for 30 minutes, checked it again and it said 94%.
That is certainly strange... Hasn't happened to me yet, and I've been monitoring my battery for nearly a week now.
It certainly seems to have more juice in though. Given it a bit of a thrashing this evening and I would usually be down to around 50% our so, it's currently at 75%.
I will monitor for a day or so to see if it is just placebo or not.

Same happened to me overnight. Went up 8%!
Further, I've now done this process 6 times meaning my battery is effectively 160% of what it was???!!!
Have we got any hardware experts who can pass a view on whether this a bad thing to do? Overcharging a car battery can be bad for example.
i've done it 7 times and still boots at 88% battery.
lets see if it did something in the next day.. =P
I've done this and on the first try, it booted with 88%. I recharged it and on the next boot it came with 100%.
Let's see whether there is any real improvement
Thanks anyway for the guide.

it happened in the same way with me.
I have 504 firmware, x10a.
Cant we use the battery information menu? There you can see the battery voltage. The maximum is 4.2V.
Forget the "Wipe Battery Stats".
If you do the steps, except the 1, 3 and 4, the result described in the "8" step will happen.
in other words:
1.Battery is 100%
2. Take the battery off
3. Insert the charger chord
4. Put the battery back and wait for the phone to boot
5. Once the phone boots up, you will notice that the battery percentage is 88% instead of 100%.
In an infinite way.
I followed the steps from the first post and the first time I reboot the phone went to 94%. I then charged to 100% and ran the steps again and this time I reboot to get 77%. I then ran the steps one more time and after reboot i got 100%. I then left the phone on standby and did not use it for 12 hrs and it was still at 87% battery. This is a definite improvement over before even on just standby I was lucky to get 24 hrs out of it and now it seems it can last about 80+ hrs on standby.
Im on .24 firmware with bluesparks rom.
first time i did this it booted at 96% then the second time 86% nothing strange as of yet

The point is to wipe your phones memory of the battery thus learning your phone a new pattern or behavior, so i belive every step from original guide is nececcary.

Yes. I arrived the this conclusion, after 5 attempts from original guide.
I told this in the post 12.
I've done this 5 cicles. It keeps showing 88% but battery life improved a lot. I had to plug every night but now it's my second day without recharging.
Thanks a lot! !!!

I've done this 3 or 4 times now and in 12 hours I've gone from 100 to 87% including a few calls and a small bit of Sat Nav. I also have Ultimate juice. Still very good and would get over 3 days with this performance.
Still 88% all the time when rebooting and wiping the stats though.
i got a new non official battery for my atrix its 1800mah...
it charges to 100% but drops to 5% in a matter of hours of light browsing and a few games...the thing is it stays @ 5% for a long time, my battery was on 15 hours and it was @ 5% for about 12 hours
ive tried to calibrate it, but im not sure if it does it right, i downloaded a battery widget that says i have not calibrated it yet...this is not my first android as ive had plenty but this is the first phone that the battery has acted like this
also i actually have got 2 of those batterys but 1 doesnt catch charge i put it on the phone and the charge screens show 5% and charging but then stops charging after a few minutes and doesnt have enough juice to turn the phone on
Try this:

Instead of the calibration app suggested in the link I just used CWM to clear battery stats, and *#*#4636#*#* to check if the battery is at full capacity.
im not rooted currently, so ill try the steps except for the jug6ernaut
thanks
Just so you know, the jug6ernaut files are actually what fixes a known battery jump issue with GB. So even if you successfully recalibrate your battery it will most likely still jump around whenever you reboot your phone. For example, you may reboot at 90%, and when it restarts all of a sudden it's showing 100%.
Ive been having a weird battery issue. my battery gauge will say its at 15% or whatever it says at the time. ill plug it in and like 10 minutes later it will say 100% battery is fully charged. Obviously its not 100%, even when I charge it overnight, when I unplug it itll be stuck at 100% for like 2 hours then all the sudden drop to like 85%. im lucky if my battery lasts 12 hours now , same thing has happened on different roms. Do I need a new battery?

I'd try a different ROM/Kernel, see if that makes any difference (after clearing batterystats in CWM).
If that wouldn't help, I'd say battery is ze dead.

tried differents and kernels, and wiped battery stats guess my battery is done
try "battery calibration" app. it helps me a lot, and keep my phone running longer. i can last almost a day with medium use.
i have also tested with on screen non-stop (wifi + online game that require wifi, brightness roughly around 30%, medium volume, with whatsapp and talkbox in between), in conclusion, i can run for 4hours plus straight with sufficient battery left. i never push it through, i think i can go for 5 hours if i want to.
battery calibration app can be found in play google store
Worst battery life evah!
Im having issue with my battery as well, I plug it in a electric outlet for about an hour last night and when i saw the charge, it was only like 49%!!!!
And today, before my meeting it was like 22%, after an hour of meeting, BOOM! EMPTY BATT! What I only did was surf and checked my calendar!
It charge slow! And its draining fast!
something happened to my battery before last month, when i charge my fone it says 88% then suddenly after few mins 1 or 2 it become fully charge,but when i unplug my charger it comes back to 88% again, i tried some apps like battery calibration and also i'm wiping the battery stats in cwm everytime i flashed a new rom and it helps my battery charge in normal and accurate level...i'm using also cpu spy to checked if my fone is going to a deep sleep. now my battery lasts for 1day 11hrs with light usage. but for heavy usage i've got 40% after 4hrs of continious hd gaming.
my ace is nearly 9 months old
i am in stock rom 2.3.6
i am facing a problem with battery charging
it is draining really very fast
last recharge lasted for 3 hrs
now i got a wierd problem when i put into charger it got back to 100 percent within 10 min unplugged it and when i start using it went down to 63 percent within 8 min
wht might be the problem any help
thanks
Looks like your battery's life is coming to an end. Check with a different battery (maybe from a friend), if it is the battery you can try these:
-Bump charge: charge to 100, turn it Off without unplugging, wait till it says it's 100 charged and turn it on, wait till it says 100 charged and Off again, repeat a couple of Times.
-Freeze it: Leave it in your phone till it runs dry (when your phone doesn't go past the galaxy ace logo and turns Off). Wrap the battery in plastic, put it in the freezer a while (an hour maby, not too much or it will die), take it out, let it sit there at ambient temperature, put it in your phone and charge to 100.
Hi people . I wanted to ask some questions:
1 - I heard that the battery prefers a 85% charge rather than a 100% charge because the battery has a limited full charges, is that true?
2 - So if question 1 is true, then by theory it was the same thing as saying: If i always charge it to 85% or 90% then my battery will never die because it never had a Full 100% charge xD , so i think there's something missing in this theory because no battery lasts forever xD, what is it? xD.
3 - When i charge to 100%, it fast drains to 90%. But if i charge 100%, reboot the phone ( it will have 97/98% something like that ), charge it again till it reaches 100% a 2nd time, the battery slowly drains 1% or less in every hour starting with 100% battery.
Is this normal? Or doing this 2nd charge will make the battery die faster/battery with less life?
4 - Full discharges are not recommended, so that means we have to avoid the battery getting 0% right? Or there is a time when we must make battery go to 0%?
5 - Full charges are also not recommend, recommended is frequent charges. Does that mean that i should unplug the cable when the led is green at 90%? instead of 100%?, does the battery last longer if i unplug it on 90% instead of 100%?
6 - If i have battery on 20% and then make some consecutive little charges until it reaches 90%, does it hurt my battery on battery life or is this normal?. Making this or charge 20% to 90% directly is the same thing?.
7 and final question - When the charge cycle of the battery reaches it's 2-3 years limit, will it still be usable ( even with less life ) or we must really recycle it and buy a new one?
Thanks in advance mates , I'll click the thanks button to the people that answer the questions properly, because i want to do it, because that means you helped me .
Cheers
1 No
2 You said it already, if 1 would be true then the battery would never die, so 1 can't be right
3 When you charge it to 100% leave it to charge for a little bit longer (10=15 mins), it will fast-drain less (mine goes to 98% in an hour or so and less than 1% after that)
4 Never let it go empty
5 Charge it when it's somewhere between 10% and 25%
6 See 3
7 Battery life will slowly deteriorate. If I hardly use my phone, I can get to 4, 4.5 days on one charge, you will notice it gets down to say, 3.5 to 4 days, then to 3 days... When it gets too short, change your battery.

3 - Reboot and charge again or charge to 100% 15/20min more is what i also do, but my doubt was about if it was safe to do that ( because i always heard that it isn't recommended to let the phone charge more time when it reaches 100% because it starts to lose force quicker ), but if you're sure about this then ok i'll continue doing it thinking it's safe to do xD.
4 - Phones really get a strong evolution holy s... xD now it's the reverse of before, because before it had to go to 0% or the battery would vitiate xD.
6 - Yes, but the question is if making consecutive charges ( without reaching 100% ) hurt the battery performance? example: i plug the usb cable phone to pc, that way the phone will automatically charge, then i unplug pc the charge stop, then i forgot something and plug usb again ) charge again ), then unplug, and then i plug the cable and charge it to 90% instead of 100% for example, it is hurting the battery life of the battery?.
7 - Wait, it's getting too short, but it's still usable?, if i use it more time it would explode in my face or give me a head shot? xD.
Thanks for the answers mate .
Cheers
About 4: With NiCd or Li-ion batteries i believe it's good to drain them every now and then, but our phone's have Li-Polymer batteries, and they go dead when they get too empty.
About 6: I don't think it hurts that much
About 7: If you're on nAa-s GB kernel, maybe going back to stock kernel for a while might help recover your battery. If not, it's maybe getting too old, but I don't think it will explode in your face. It doesn't get overly hot when you charge it does it?

4 - Li-ion i think it's only a little worse than Li-polymer in that drain thing, if it's a normal phone it will vitiate for sure ( i had many phones and they all vitiate ) but now i have a Lg gt400 smartphone Li-Ion and the battery seems very stable without vitiation now ( it vitiate in the beginning by lasting 3 days instead of the normal 5 days, now it's always 3 days ), and the phone i use now xperia mini pro x10 Li-Polymer it didn't vitiate or lose any strength, on the contrary i think it got better because now it lasts 3 days ( it would last 4 days if i didn't hear 1h music a day ) and in the beginning it only lasted 2 days and a half, this is crazy s... xD.
6 - Now it doesn't hurt, but maybe in time the effects will be more visible when the battery starts to lose capacity, that's what i'm afraid of :S xD.
7 - The battery status is Good now, i was referring to the future, if doing these consecutive charges don't hurt phone ( make it die faster than the normal 2-3 years of life ) then i'll stick with Naa-14 with Gb Rom, but yes if i start to feel that the phone is getting weird then i will go back to Eclair original. No it doesn't get hot, i don't overload the battery too much and i take good care of it xD, so that means that even when it's on the 3 year of life ( where the battery should be replaced by another ) i can still use it with no danger ( even if it only lasts a day because it's weak)?.
I also got a nokia 5700 for more than 4 years and the battery barely lasts a full day now but it never had any problems of getting hot or being crazy, so it's still safe right?. I don't wanna be killed by a phone xD kidding xD.
