Thx a lot for this man.

Really informational post, have been wondering about this :)

I am running at 3615mv and my battery level is shown as 12%. When it was 100% I had 4165mv.

Is it OK or is there a problem?
[Desire General] Etherial:
Well I stumbled over this when installing a new Rom yesterday. The new Rom seemed to help my battery but now my phone has been shutting down at 20% battery which is around where I get to at the end of the day. Hopefully this calibration will fix it. I had to do the cycle around 4 times to get the battery up to 4.175mV. We'll see how tomorrow goes!
[Desire General] mohsinraza:
Charged my phone to 100% turned off and connected the charger.

It went green straight away. Missed some trick?
[Desire General] Etherial:
Well I'm not sure it did anything for me. Today's run was average (no different to normal that I noticed) and my phone still shut off at 18% this evening. :(

---------- Post added at 08:12 PM ---------- Previous post was at 07:56 PM ----------

This happened to me the first time too. Make sure you unplug before turning off.
[Desire General] mohsinraza:
Yeah I did.
[Desire General] deepgrass:
If I left my phone overnight (around 8 hrs) with screen, wifi and data off. How much battery would it take?

Mine goes from 100% to 94%. Is it normal?

Airplane mode on or off? Running any programs like setcpu? Which rom do you use?

Hi there

If I did all this but without wipe battery stats at the end can i do it again?
[Desire General] crni6:
I do it today and I notice that my phone goes to 99% before and now 100% but nothing happening...still when I use phone on normal ussage battery indictor shows 1% down every 3 min. or so...and when I play games it gos 1% every 1h. And when my phone was off on the charger imediatly show green light(at this procedure). I do something wrong?
[Desire General] alienex:
Since having my DHD about 12 months ago I have flashed it too many times and measured battery life like a right geek!

Anyway, my current setup is MIUI 2.2.17 running SPB Shell 3D. I use Green Power to control WIFI, DATA and Bluetooth and Sync settings.

I undertook this method of calibration and I have something to share hopefully which worked for me at least and has defintely seen an improvement. My battery widget after using this method showed a battery life of 55 hours as opposed to 17-18 hours, using basic functions such as a few calls a day, few more texts and the odd WIFI/DATA connection.

My max voltage has also increased as a result from 4174 to 4199mv

This is what I did:

1) Plugged my AC charger in and charged to 100% and also waited until the current widget installed showed 0mA charge.

2) Unplugged it and immediately powered down.

3) Plugged the charger back in, LED went orange for about 3 minutes and then went green

4) Whilst on charge turned phone on and then waited again until current charge on widget was 0mA

5) Repeated steps 2 & 3 & 4

6) Whilst on and plugged in, I then calibrated battery using calibration tool from Market free and wiped my current widget history and other battery widget stats.

7) Unplugged charger and then used phone

This is where it got interesting, straight away the % dropped in a matter of miutes to 98% and then decreased fairly quickly (about 5-6 hours to about 35%) and then it skipped and dropped to 9% and then quickly to turn phone off.

Bugger!

So I repeated the process again above twice more , basically forcing it and making sure I calibrated after each process.

ok - I wake up and my alarm goes, WIFI turns on and syncs my email and turns back off and then I look at my phone after my SMS from my girlfriend and hello!!! It's still on 100% :D

My experience now tells me that something has altered, it has never done this before, and in fact the method has worked, I didn't put the phone on charge yesterday night being able to trust that there was enough % left to last over night. And when I woke up there was still 56% left.

So nice work guys for the great tips!!!!!!!!!!
[Desire General] Atrax2010:
I have followed the procedure exactly, even wiped battery stats, but the problem I'm having is that when I fully charge the phone (powered off), i disonnect it, and by the time the phone boots up, the battery is at 98%.

I plug it in again (powered on), it gets fully charged (4187mv), and then I power it off again, plug it in (it allready red LED), charge it till LED goes green, power it on and again it's at 98%.

I've been battling with my DHD battery life since I bought it, it gives me barely a day and a half, no matter what ROM/Radio I use.

But I think that maybe it's normal considering my usage.

I have auto brightness, always on WCDMA, auto sync(but I only have gmail and weather syncing, once every hour), I also have widgets on every screen (digital clock with weather, big weather widget, calculator, calendar, power control, and big bookmarks widget).

I make around 5 short phone calls a day, and some messaging, and some internet via wifi/3g, so not alot of usage, not even camera or music.

I've even striped down all the apps I don't use and I have nothing working in the background like facebook or anything.

I have set up ROM to High Performance, and "never sleep" policy.

So I guess that's normal battery life, considering the usage.

But the problem I think is that even when the battery is fully charged, it's at 4187mv.

And over night, I have it plugged in my computer, so it's basically charging all night, is that OK, or should I not do that?
[Desire General] thedarkcoder:
I did this guide, and now hoping to see improvements. But, only one thing. My charged battery voltage is 4079mV. Does this mean that the battery is too old? Do I need to replace my battery? Thanks

[Desire General] Igor2410:
people please help any way you can. my battery is all messed up. with each calibration I make it is worse. nothing helps. I tried with various ROMs and kernels. The problems started when I was at Supernova and not in the begining but after few months of using it. Last night I put Cronomod with manu kernel and immediately calibrated. Phone was charging overnight, I plugged it off at 9 am and he died at 9:10 at about 90%

*

and all the time it dies at about 85-90 %.

I still left with only two possibilities that I will try. Put cronomod with cyanogen kernel and try again, and then with oxygen which was last that it worked.

It worked when i calibrated it with oxygen last time, but as soon as i changed rom it was the same

*

For each calibration shows me that it was successful.. Chgtf is lit and value is 0x81. After each calibration in my batery batery calibrator shows age 50%.

*

I noticed that when the battery is at 0, it charges about up to some 20% and then immediately jumps to 100 and the indicator lights green.

Is it possible that the battery is bricked or something else?

[Desire General] Kootee83:
How long have you been using this battery, and when did it began to do so?

---------- Post added at 12:24 AM ---------- Previous post was at 12:15 AM ----------

Firstly you should stop calibrating it. Li-ion battery shouldn't been discharged to few % without special reason.

Did you tried to charge on telephone powered off? Is there any difference when you charge on tel powered on or off with this percentage jump?
[Desire General] killphillxr:
thank you, I will try
[Desire General] erklat:
Stunning how much people read this thread and remain under impression this is how calibration is supposed to be done. The only real calibration is through Nexus calibrator by Jon Richards and everything else such as deleting batterystats.bin is just foolish.

This thread should have tag 'deprecated' or something similar.

Well, i tried this, and yesterday my phone shut down at 25% remaining... and since i was using sandvold's ics, the phone got into a bootloop... damnit, i was so carefull not letting that happen, and now i was forced to reflash the rom again.. oh well, i will try again when sandvold finally descides to make an update..

It works!

Hi guys. I did this thing with turning on and off the phone. For me it works PERFECT. Usually I am taking my phone around 09:00 in the morning fully charged and in the evening (around 10PM) the battery is about 15%. Before one week I even ordered a 2400mAh battery from ebay.

I did the turn on/off thing yesterday in the morning even earlier - 08:00 AM. Yesterday around 10PM the phone still had about 60%. Today I am still using it with the same charge (about 2PM) and it still has about 40% of charge. I am using it the same way like before - apps, calls even now the WiFi is always on!

It's amazing, definitely give it a try!

:victory:
[Desire General] WereWolf90:
hello, i have a HTC Desire, and it worked fine, untill one day i installed a new rom with the battery at 100% and from then when my battery reaches 20% the phone is automatically shuts down... and when i put it to charge and i power up the phone... it says 0% battery... i wiped out the battery from the Recovery.. i use 4EXT Recovery... and i don't know why... my battery at 20% is shuting down the phone... it is damaged??? :(

1400 ones. Stock like.
[Desire General] PuffMaN:
I would recommend the 1600mah mugen power battery. Takes a while before you get it, but well worth the wait.

[Desire General] abaaaabbbb63:
Mine shuts down at ~23%. I never reach that value. So I wouldn't replace it yet.

[Desire General] PuffMaN:
Well, mine shuts down at 0% but... With at least 3.7v when it should shut down at 3.2v. After many calibrations, this never gets better. So i now use the app to get more juice out of the batt when needed. But if anybody has a solution for this i will be glad to hear it :) using a mugen power 1600mah batt.

[Desire General] crenchy:
I know this thread is several years old, but I wanted to share my experience in the hopes of getting further suggestions. Hopefully, someone is still subscribed to this thread.

I have a HTC Desire 626, and am experiencing all of the battery drain/shut off issues described (fast drain, percentage decreasing while plugged in and charging, random percentage shutoff, "restarting app __ of __" on startup, etc.).

To this point, I have tried installing a microSD card to increase space (I now have about 4.2GB, or 25%, free), using the Norton Clean app, wiping the cache partition (which worked for about a week), rebooting in safe mode, and running a battery calibration app.

Today, after reading these instructions and the tips that followed in this thread and others, I performed these steps:

1. With phone turned on, charge to 100%/green light (it took all day, and I had to unplug my charger from the wall, wait 10+ seconds, and plug it back in before it would charge without interruption).

2. After light turns green, allow to charge 2 more hours.

3. Disconnect phone and power off. (It immediately dropped to 99% when I disconnected.)

4. With phone powered off, reconnect to charger. (The light turned amber, and held at 99% for a while before turning green again.)

5. Allow phone to charge for 1 hour after light turns green.

6. With phone still powered off, disconnect charger.

7. While disconnected, power phone on. (When I did so, I got the "Restarting apps" message, but not the "Restarting app __ of __" message.)

8. Power off.

9. Reconnect charger and charge until light turns green.

10. Charge for 1hr after light turns green.

11. Reboot to bootloader.

12. Access recovery mode.

13. Wipe cache partition (Advanced -> Wipe Battery Stats wasn't an option).

14. Reboot phone.

When my phone finished rebooting, the battery percentage was 89%. It dropped to 87% within 2ish minutes.

Since it's been turned on (less than 30min), it's received a few E-mails and updated two apps. The percentage is now 82%.

Any suggestions as to what I did wrong, could do differently, or how to fix my problems?

Thanks so much.
[Desire General] N3m3515:
i used this method half an hour ago and my battery drops 2% since then without using the phone in any way. i am using official htc froyo rooted with market fix
[Desire General] Dany0:
Here's what I summed up from all the advices:

1.) Let the battery drain out till the device turns off or there is just 4-5% left indicated

2.) Take out the battery+sim+MicroSD card and wait 30 seconds to 2 minutes

3.) Place it back

4.) Turn on the phone

5.) Plug it in the AC charger

6.) Charge it overnight, once 100% let it charge for 2-3 hours minimum, 8 hours recommended, 12 or more hours for best

7.) Plug out the charger

8.) Turn off the phone

9.) Wait few seconds

10.) Put the plug back

11.) If it's charging let it charge until green light+2 minutes. If it's green let it be charged so for extra 2-3 hours

12.) If you have ROOT go to recovery and wipe battery stats.

13.) Reboot

14.) If you had green light turn off and take out battery for 30 seconds - 2 minutes, and wipe stats again. Then charge till 100% again when turned on, and charge till 100% again turned off, then just reboot.

14a.) If you've successfully charged it to 100% and wiped battery stats, try to charge 100% again turned on and again turned off. Just in case. If it's okay continue using the device.

15.) Download Battery Doctor/overcharged and check if the voltage is more then 4150mv. 4197mv is the best = successful. 4150mv-4197mv = quite successful and <4150mv unsuccessful.

So if you really hate your desire's battery life, do all the 15 points. If you're okay with it you can shorten it.
[Desire General] Lennyuk:
There really is no need to drain the battery if your planning on wiping the stats anyway.
[Desire General] misterdev:
I have disconnected my phone at 12:20, after following the instructions, and wiping the battery stats.

It is 18:05 and I have "finally" lost 1% !

I am actually at 99%.

1% in 5 hours and 45 minutes. I have never seen that.

I am really impressed !

I am running leedroid rom (froyo)
[Desire General] Dany0:
It(well it MUST have to) calibrates the battery module. Plus it's healthier for the battery when it is full for a long time.
[Desire General] b6rt:
Wow it really seems to be too much :eek:
[Desire General] Dany0:
As I said, if you were/are really upset about the battery life do all these things, you won't regret. Although it's not THAT big difference, few percent maximum, but it's still better then just calibrating the battery(since this all may increase the battery capacity after all)
[Desire General] donbronzi:
I found this thread a couple of days ago for the evo 4g and did the procedure in the first post. I noticed the difference as soon as the phone was unplugged there was no big drop. I have since used it for 2 days and have noticed a longer battery life.

Have you turned off everything?

I lost 10% in 3 hours after calibrating the battery.

I've also read that performing a regular data wipe wipes battery stats. Not that you would want to wipe everything to get it done, but it doesn't need to be a separate step if you are flashing a new ROM.
[Desire General] KBanause:
I installed several ROMs and did a wipe each time but it never wrote to the screen that it wipes the battery stats.
[Desire General] Lior84:
I Charging it now for about 4 hours. Just checked the mV after the led is green about 1.5 hours and it shows me 4206mV (yes this is not a mistake). I use battery info widget.

Is it possible to go till this number truly ?
[Desire General] cyron_at:
the same here...
[Desire General] nitrox1:
Hello all, did something like this battery reset earlier, but now my phone powers off at 7-8%, instead of getting to zero. Any feed back?

Also would it not be better to reset battery stats at zero charge, then charge for 8 hours till it's full, to allow for a low and high point?

Sent from my 8-bit ZX Spectrum using semaphore.
[Desire General] Lior84:
Just did the wipe and powered it off and then connected to charger again. Green led showed immediately. Booted into recovery and wiped the battery stat. Now, turned it on and in the battery info it show me 4138mV.

how is that ? before the first turn off it showed me 4208mV.

So now it connected it to the charger again and after 3 minutes being connected (green led all the time) the widget shows me now 4197mV.
[Desire General] Nuntius:
The LED stayed green all the procedure long!

Don't forget that, even after this procedure, the battery gauge isn't necessarily to be trusted!

I have followed this thread very closely, especially the posts from Vidler & LennyUK.
