[HOW TO] Calibrate Desire Battery

Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.
Mod Edit: There have been a few reports of damaged batteries by people on this thread. There is a chance that this MAY damage your battery. Please bear this in mind if you choose to follow the instructions above.

supportyou and the app!

Thanks for that. At what point do you wipe battery stats? After the process is complete?

Also wondering about this

You should wipe battery stats after its fully green (when powered off) then boot the phone back up.
You only need to do this once
I.e.
Charge till full when powered on
power off
charge till full again
boot into recovery wipe stats
boot and continue to use as normal

It works!!!
That's fantastic!
I read this topic this morning and tried immediately. Since this morning i only lost 4% until now. That's great news!
Thx a lot, man!

first post

takes a long time to charge my Desire, but then i'll test this one!
Hope this will make battery life better. I have the same problem as described in first post (drops immediatly from 99% down to 93% )

Can someone suggest me how should I go about doing this if I use multiple batteries?
I'd imagine the phone can only be calibrated to 1 battery. But if I were to use another battery, would I screw up the calibration to the original batteries?
Right now as it is with moderate usage I need 3 batteries to last me through the day. :S

3 batteries?!
What rom are you using and how exactly are you using your phone?
I have just one battery and it lasts about 2 days with moderate use.

I am using this ROM: (sorry can't post link)
[ROM] Rooted Official HTC Android 2.2 (FroYo) ROM [Market issue fixed]
With my typical usage, I unplugged the phone in the morning from the charger, by the time I knock off from work, I would have left about may be 20%. With stock ROM and a single battery, there is no way that I could last 2 days with one single charge. My main use is web browsing, RSS, Facebook and IM. My estimation of my solid screen time is about 2-3 hours.
So I bought more battery just in case, and played with custom ROMs. I ended up using up a whole battery in 4 hours or so. Definitely something is wrong here. My gut feel is that both the ROM and batteries are suspects. Being a newbie I really need enlightenment.

Is it really needed to wipe the stats? I think I've accidently done this once already... cause the battery life is much better.

since this procedure, my battery stays at 100% since nearly 2 and a half hours now and i did 2 text messeges in between and recently checked the bat about 4 times
this couldnt be possible..
i mean the battery is almost doubled in comparison to how long it lasts before
is this possible??

yes it is possible

but how?
i mean in this time the battery would have been dropped to arround 97
and now its still full?
i mean these are stats how are they increasing battery life? the batterylife is given from the cell itself?

[Q] Yet another battery drain problem

Hey guys,
When I first got my Desire I calibrated the battery after the first couple of days (when I found out how to do it), and since then it's been great. But in the last couple of weeks, it seems to get a bit lazy. So I thought I'd try and re-calibrate it.. Booted into recovery, wiped battery stats, did the process again (charge while on, turn off, charge again, etc) And now..well..I unplugged it at 6am and it's flat as a pancake now at 2pm..
My question is, there are so many different methods for calibrating, which would be the best one for me to use right now? It isn't turned on atm, and I don't want to charge it until I know what I'm doing. Hope someone can help me out

Maybe the problem is not your battery but a app or widget.
You say, after the calibration it was good.
Have you installed something new?
Edit:
The calibrate method I used is:
- charge full
- disconnect from cable and shutdown phone.
- charge till led is green
- disconnect from cable, start phone and shutdown phone
- charge till led is green
- Disconnect from cable - wipe battery stats
- Done

Yep that's the method I used.
Just done a complete wipe of everything and re-flashed InsertCoinHD2.0.0
Just gonna leave it with minimal apps, Facebook, eBay, etc for a couple days and see how that goes.

Looks like it hasn't worked
88% after 1 hour 27 mins
70% after 2 hours 40 mins

Sent from my HTC Desire using XDA App

Calibrating your batterie has only to be done once. If you flash a new rom, it's normal for the batterie to go that fast. You should wait a few days before everything is working as it should.
So your focus should be to find a clean rom, don't install any apps and just try it for a few days. After that you could also try messing with havs kernels.

I suppose this is with screen off? You should download current widget from the market and log your batterie usage. If the usage is around 5ma (lower = better) and still have a high batterie drain, then your batterie is damaged. But if the usage is higher then it's a software problem But then again, if you flash a new rom every few days it's normal to have high batterie drain.

Just tried it and wow 458mA! I might take my desire back to stock, original RUU and s-on and such.

That's normal if you have your screen on. You should enable the log function and leave your screen off for a few hours.

Thanks for that I've been flashing ROMs and such for a while now, but this is the first time I've had any problem with the battery.

Just a little update.
I figured it would be the kernel I was using (InsertCoinHD 2.0.0) as I'd heard a lot of people have the same trouble. Reflashed to v1.9.5 and the battery is going back to its old self, 61% left after 8 hours with moderate use, since reflashed 3 days ago Thanks to all who helped

Well,... I got amazing battery life on Aerovan's kernel v9. I never tried the newer kernels. And I get pretty good battery life with the TSM UKB ROM too. I think I am on radio 1111... Hmm.

If I don't use my phone I have 84% at the end of the day. CDMA on (not in airplane mode), wifi on.

What are you synching during the day and at what intervals? Governor and Min Max Speeds? Do you live/work in a crappy signal area? Use a lot of bluetooth or wifi?
I uninstalled facebook and twitter and whatever else asks you for your first born child permission wise, and stopped Maps from starting at basically five or six different system-wide events.
Purchase Autostarts from market and see what is running during each system wide event.

everything is stock in terms of intervals, and governor, and cpu speeds.
I travel all over, so my signal strength goes up and and down. But I think you may have hit the problem.
Before flashing (stock) I pretty much always had 4-5 bars wherever. After flashing (s-off, root, etc), I have never had above 2 bars.
Using my home as an example, I normally had 5 bars of service. Now looking at my phone, I have 1.
Internet speeds are fine (250kb/s down 87kb/s up). Phone call quality is the same.
My signal Strength in front of my computer is -77dbm. Outside my front door is -102dbm.

I wasn't getting the battery life i was, so i did flash v9 and i'm back at 1% battery loss while phone is unused. I wasn't getting that with v10 or v 10.5. I could barely get a day between charge. I should get 2 days with v9 because i did before.

You can try other radios. I understand some have better effects than others with each handset.
Also, I tend to update PRL and such before installing a new ROM using a stock ROM.

I have already tried the two recommended radios. The funny part is 0322 was the radio my phone had before I hacked it.
after flashing each rom you have to program and that updates the PRL anyways.
But just to be sure i did the roaming capabilities, and no change.
Ill try v9 of the kernel. anything else?

Do you have the Facebook app installed?

May not be the answer your looking for but try an extended battery. I bought one a week and a half ago for $5.20 from amazon. Its the 2150 mah. And this sucker lasts all day. Using kangdemnation 0.3 with stock aokp kernel oc to 1.5ghz. 13hrs later and at 59% with low usage for 6hrs (work) moderate for an hr and heavy for 3hrs and then back to low for the rest of the time.

Na, the phone was fine on battery before the hack, from past experiences it's always been even better after. Maybe I'll restock and see if that helps.

Yeah Facebook has been performing poorly on many people's phones especially while on 3g. Sometimes loading very slowly and sometimes not at all. It has also been causing a wake lock problem which I personally experienced that wakes your phone while it should be asleep (not the screen just the os.) That causes battery life to be poor for many users.
I hear that FriendCaster is much better if you want an app to replace the app! Or some are using the mobile site if they don't care about notifications. Personally I just uninstalled Facebook after I started having problems and haven't been on Facebook since.
Try uninstalling the app and see if that helps. It nearly doubled my battery life when I did.

If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors, and re-calibrating the battery along with these steps may help, may not. But, worth a try anyhow:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM (if installed) or use Rom Manager (is device is supported).
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.

I also support FriendCaster. The facebook app hardly worked when I used it. The only time it half worked was when I was home and on wifi. I actually like what FriendCaster...I like what it does with the layout and I feel it's a lot more intuitive then the official app anyway. Plus for some reason facebook had become a datahog. This could be OPs problem in terms of battery drainage because Im pretty sure they download a lot in the background.

Low precantages of battery last much longer (without power saver)

I've searched the internet for that problem and found nothing so I'm trying my luck here.
My battery precantages is not linear at all.
When I'm discharging the phone from 100% to 0% the precantages drop really quickly until 5%-9% (Disabled battery saver when cross 15% of course) and then the precatnges seems to stop draining and every precantage last longer and longer until it gets to 0%.
From 100% to 0% I've got 2:45 screen time in my last test but between 100% to 5% it was only 2:15 screen time!
Meaning that every precent lower than 5% last 6 mins vs. every precent above 5% last 1.35 mins.
It's very annoying and happened to me also on unrooted ICS and then on unrooted JB and also on every rom-kernel combination I ever tried after I rooted my phone. (ARHD, OrDroid, Maximus, CM10.1, Renovate + NCX, XM, Komzik and stock of course).
Do you think its a hardware issue? Do I need to replace the battery? Or it's a common problem of HTC One X?

It's not a problem, it's a feature.

How's that a feature if power saver is off? Don't get the idea. I prefer that every precent will be equal. It decreases screen time alot if you don't reach the last precents. By half an hour! That's absurd.
Every precent can be 1.65 mins of screen time and by the time I will reach 10% I will have 2:28 screen time instead of just 2:10.
If it's really a feature so it's a bad one, How I can disable it?

The file is deleted when the phone is charged.
The file has nothing to do with the displayed battery percentage remaining.
Deleting the file manually is a pointless thing to do.

So if it has nothing to do with my problem what does? I already installed various of roms with various of kernels and the problem persists. I have already full wiped everthing for too many times. Maybe it is an hardware fault of the battery indicator or somthing like that?

A ROM or kernel won't change it, the battery itself indicates what's remaining. I guess the lookup table or whatever is not well calibrated for the cells in your battery.
Get over it, it's not a big deal, you can't fix it other than replacing the battery, but that's not guaranteed.

To me, any HTC One X that lasts about 6 hours with 3 hours of maximum screen time has a hardware issue.
I have similar problem ever since I bought the phone last May.
Just by looking at http://forum.xda-developers.com/showthread.php?t=2156311 makes me wonder what the hell is wrong with the phone itself.

So most of the One X's that I know are borken. I know 6 people that never pass 3hr screen time with their phone. and in XDA I see 7hr screen time and can't believe it, even if I turn off all the sensors like GPS, Bluetooth when not needed it's not helping me to pass the 3hr...

Yup! Turning off all sensors, GPS, data doesn't help.
When one turn off the screen at eg. 70% then turning back the screen on after an hour of sleep time, it will drop to 65% or worse. Always made me mad when that happens.
Even any battery saving guides like getting rid of wakelocks doesn't help.

I usually get 5 hr screen time but depends a lot on what you do. 3G data drains battery faster than WiFi, GPS doesn't drain battery unless an app uses it, etc.

Really desperate here...

My battery discharges pretty quickly and I just don't know what to do anymore...
It usually goes down pretty fast when I'm connected to wifi. I think the main culprit might be Kernel (Android OS). Please take a look at some screenshots I took while using the Gsam battery monitor app and Better Battery Stats app and correct me if I'm wrong.
I have stock ROM, stock Kernel and my Radio version is: 5.1204.167.31
What do you think I should do? Change the Kernel, Radio or maybe both?
And if so, what would version would you suggest for my stock ROM?
Or should I just replace the battery and hope that fixes the issue...

Wifi will definately drain it quicker, usually keep mine turned off until I use it. Depending on how old the phone is definately affects battery life, mine is now just over 2 years old and I find that although it charges to 100%, it will drop to 91% in the first 5 minutes of using it. HTC has a self test in the dialer enter *#*#3424#*#* then follow through to the battery test. I think phone needs to be in airplane mode and has to be fully charged, then leave it on for an extra hour or two. Test takes an hour and from memory if battery is above 70% it passes.

Mine does the same. It drops to 91% fairly quickly after charging. I did the HTC battery test about a month ago and it showed 81% battery left after the test (it said that if it's below 70% the battery might be faulty).
Since I made this thread, I managed to change the stock kernel and now I'm using Alex's kernel. The battery usage is much better but still the Android OS or kernel drains much of the battery.
Do you think changing the battery completely I might have better results?

Have you tried lyapota's #17 or XM's #17 kernel?

Before Alex's kernel, I tried XM's latest kernel because I read on OP's thread that it works with stock ROM too, but I never managed to boot my phone after flashing it. (and I did everything right I think: cleared fastboot cache, fastboot flashed the boot.img then flashed the zip in recovery)
I am all for trying lyapota's kernel but the download links have been removed in the official thread I think. Can you provide me with a link for downloading please?

Try app called greenify

Thank you but I am already using Greenify.
Only one option left, to try and remove some bloatware stock apps and see if that changes anything.
