[Q] How to calibrate battery empty point? - HD2 Android Q&A, Help & Troubleshooting and Genera

I've already wiped battery stats, I think I'm getting full charge, and I'm getting pretty good battery life (over 24 hours last run).
The problem is that Android can't seem to tell the appropriate 0% battery point. Several times I've had the phone shut down when the battery life is at approximately 20%. When I try to reboot, there is not enough juice left to make it even to the multi-boot loader.
Is there a way to recalibrate the dead battery point so Android reads correctly?
BTW, I'm running Darkstone SuperRAM Froyo 1.5. (SD/RAM build)

have you tried turning off the phone and let it charge to 100%(when you dee the green notifiationled) and then turning it on. and then wipe the battstat.
just an idea, always used this method if the phone cant charge past 99%, maybe it wil work to on the dead point.

Yes, that's how I wiped the batt stats the first time, which greatly improved battery life. But now there is the power off at 20% thing. Strange.

Then its the roms fault some things are just the way they are. Mine goes to 15% and shuts down. The build I'm now using goes to 8-7% with 100% charge. What Rom u using?

Oeps, you're running syperram I see I had that same problem with superram. I just live with it try nand roms!
Sent from my HTC HD2 using XDA App

i think it's the build's fault. me and a fellow xda user also experienced the same thing with superram.

Thanks for your help! Guess I can stop searching in vain for a fix. I love the build otherwise - the only one that hasn't given me sleep of death with TMOUS.
Unfortunately I can't go NAND yet due to a crappy WM application I need to use for work, which isn't available in android.

See if "Tasker" app can do an auto shutdown at 20% and keep a spare battery in the pocket if you like SuperRam. I like SuperRam and it's my build of choice. Not a fix, but a spare battery in the pocket is good anyways.

battery, battery and less battery.

Uptime: 2hours 27minutes and x amount of seconds and dead.
did I break the record for stress testing it?
Anyways, anyone got any tips on battery life? I was thinking of getting 3000mah or 3500mah, but the design of it (bulky) just doesn't seem the right option in my mind.
Also anyone here actually have the 3000mah or 3500mah so they can chime in on the design + battery life compared to the original?
just powered the phone back up. and it says battery is at 50%. wtf.
It turned off on its own cause of low battery, and now it says 50%?
E-gad the ghost recharge strikes again.
I had the same thing happen this morning. Woke up to a dead phone, plugged in, boot ed and battery showed around 70%... Go figure

Battery may not be calibrated correctly. I have to say my only major disappointment with the EVO is how the battery life is so tied to the particular rom I'm using. I mean I expect different drain rates on different roms, but having to recalibrate the battery every time I switch roms is just plain dumb.

Juice defender did not do it for me either. I got 1.58 but too many things were turned off to get there. What is the purpose of a smart phone if everything has to be turned off to save battery.

It used to work for me, but now it is doing the same thing. Im at 1.76 now but for the past week it was stuck on 1.00, then slowly went up with each flash.
just a quick update. The reason the battery showed empty one minute and then it showed 50% the next was because of the heat. The phone was very hot when I was playing with it, and then when it cooled down it seemed to have fixed itself or w/e. Happened again today.
im sure its been answered..but how do we calibrate the battery?
Pretty sure you can erase the battery stats through clockwork recovery. Also there is a way through ADB which is pretty easy too
Sorry I don't have any links atm.

CM5 or CM6 Battery Life ?

Which provides more battery life.
Im on CM5 now and my battery dies SO FAST you can almost see it going down just watching the screen, i have the screen turned all the way down, use only 2g networks. ever tried to under-clock, when i check battery usage says system idle uses 49%
any ideas ?
Are you serious?
Better yet, don't use the phone at all, that might save the battery.
Dude with those settings its like having a 20th Century device.
Flash another ROM or something, try wiping battery stats, it has been suggested all over the forum...
Why do I even bother...when the mods see this youre a gonner anyway.
It's not so much the ROM, its the apps and widgets you have installed. Some are poorly written, some don't play nice with other apps or certain set ups.
All you can do is install a monitoring app like system panel, and remove the apps that are using alot of CPU.
That's what I have done.

and thank you for your helpful reply i will look into the apps i have.
EDIT: Battery usage says system idle is nearly 50% of usage, even after i kill all the apps :[
LOL! Wow, someone's a little edgy...
It's definitely not a "CM5 issue" that would be fixed in CM6 (CM6 is still in RC, CM5 has had several stable releases!) eyegor's suggestion to wipe battery stats was probably good advice believe it or not. Charge full, power off, leave plugged in. Boot into recovery and wipe battery stats. Power down, unplug and start up, let it drain allllll the way.
Check out xda homepage even - a battery calibration post!!
Battery life is pretty variable as you can see in the numerous threads on this topic. CM's forum has one with a poll with most saying CM6 is better, but not a clear cut answer.
I used SystemPanel's monitor function to identify which app was eating battery. It worked great! My biggest offender was Weather and Toggle widget. I loved its customization but its battery gulping was just not worth it. Got rid of it and my battery life is much more consistent.
I also got a cheapie battery off eBay which helped.
Both CM5 and 6 run perfect on my phone. No battery drains.
My point was that you're in the wrong section, pal.
You also might want to watch logcat while the phone is idle or sleeping to see if there are numerous errors or warnings scrolling by when there should be very little activity.
I have a similar issue. Initially I had the rediculous drain, but as mentioned wiping battery stats from recovery fixed it for the most part. Once it says its fully charged and you turn the phone off, let it sit charging overnight. Then wipe the stats in the morning and don't charge again until the phone turns itself off. Only issue I have now is that when I've got my GPS turned on, in use or not, it kills the battery. While in use I get about 2 hours from a full battery to the phone turning itself off. Haven't figured that one out.

No worries. It freaked me out when I first flashed 5.0.8. I use my phone as an MP3 player in my truck with it plugged in to my CD players AUX Jack. Did a 5 hour road trip and only lost around 10% including a few phone calls.

Rom with the best battery life

What Rom is getting the best battery life these days
also doesnt matter if its sense or vanilla or stock OTA i just want good battery life

from what i can tell, battery life is MOSTLY tied to the kernal. Try an undervolted one, i've found they all work pretty well (hydra and KK)
o alright im using kings #2 BFS kernel undervolted and underclocked
I research before I got my DINC so I never used the factory battery from day 1. I have the same size battery but is 1750 power rating... I think Verizon has a newer one which was before I got mine...

Not directly related to the ROM. Check out the Hydra kernels. Also, with regards to battery, you need to do some recalibration so it works better. I got the 1750 battery for the DINC and it was dropping battery very fast no matter which ROM/Kernel combination I used. Finally found a thread that discuss how to get the OS to read the battery levels better. As an example, my battery would run down from 100% to 90% within 10-15 mins! After trying the following, everything works better.
Here's the thread: http://forum.xda-developers.com/showthread.php?t=714471&highlight=battery
Here's a summary of what you need to do:
01. Power off phone and change battery to full level (Green light).
02. Unplug the power and plug it back in. It should take another 15-20 mins to go green again (there's a thread discussing this also -- "bump" charge).
03. Turn on phone and go into recovery mode. Remove the battery stats.
04. Reboot phone and use without recharging until the battery drains completed - i.e. phones shuts off. May want to turn it on once it shuts off.
05. Charge normal and you should see a positive change in the battery life.
Hope that helps.
Yeah but how much do you really gain by doing all that? And how often if at all do you have to do it again. I have the 1750 and it seems to depend allot of what kind of signal and which radios are on.

Of course if you had bad or no signal, the phone will use up more battery. Normally when you don't have any signal and you check the battery status, the phone tells you to put it in Airplane mode to conserve battery.
For me, it's worth doing because my battery does not drain as fast for my usage. Since I did this over the past 2 days, I've had the phone one on a single charge with about 6 hours of Awake Time (gaming, Internet, phone calls, texting, emails, some GPS usage) and UP time is 22 hours. And the battery is down to 20%. Definitely an improvement for myself so just try it if you like and see how it works out. Everyone's usage is different so it's hard to quantify.

bump charging before wiping stats makes no difference. bump charge is still necessary regardless. until htc acknowledges its a problem and fixes it on their end, bump charging is a part of our lives if you want a fully charged battery. unless you use an external charger of course.
I charge externally and I still bump charge tho I don't need to power the phone on and off. Also the bump time is much shorter

Nah, Virtuous gets really good battery life, especially with the custom kernel built for it.
Does JuiceDefender even function on CDMA phones? I thought it wasn't working
I would also like to know this! What about SetCPU profiles too? I just want the best possible battery life, speed is not very important to me.
So, who has tried out various ROM and Kernel combinations? What have you concluded gets the bets battery life? Thanks!
im in the proccess of downloading and setting up virtous ill report back with different kernel set ups. i just want a rom and kernel set up that will last easily the hole day
Bump charge with or without battery stats wipe doesn't seem to make much difference for me. I plug in at home/car/computer and carry a spare battery. Just wish there was a way to turn off 3g and force 2g with Verizon on CDMA phones. That way I could still have data/internet.

LG GT540 battery drain very fast

I have LG GT540 with android 2.3.4 cyanogen and the battery is just getting drain to fast ( its new battery) .when i go to battery use i saids that android system use 99-100% of battery waht its not normal ( my friend has about 7-8% use) and she last for 1-1.5 hours with normal work ,in idle about 4 hours till battery drops dead. Phone is getting to hot , i tryed to put others 2.3.7 and its same again what sholud i do.
solution i tryed: wipe battery stats -didnt help
going from 2.3.4 to 2.3.7 -didn help
PM me to see pic cuz i am new here so i cant post outside links at the moment.
Did you wipe data when updating to 2.3.7? If not, try it (maybe also without restoring stuff from backup, if wiping+restore does not help)
yes i always wipe data/cache/dalvik cache so tahts not issue,can i format SD card is she a problem maybe?
yeah same for me i am also using a rather new battery
The battery level stays on some percentages longer than others.

what worked for me
Hi
I wanted to thank for Zoe Rom on its thread, but i cant write on developer's threads yet (altough i clicked thanks button there).
Im glad i finally got rid of my memory hogging default rom and now i have a properly working phone again!
Also i wanted to reply there (to some people also complaining about battery endurance on GT540 on Zoe Rom) how i fixed my battery main problem.
Pic of current battery drain:
http://postimage.org/image/d8o8uusd7/
As you can see i am aproximatelly at 50% battery after 1day and 11h of not charging.
I had 2 problems:
1- Battery lasted aproximatelly 5 hours on standby (and i mean i wouldnt even touch the phone and the battery was gonne after that time)
2- During intense battery drain usage, the battery was reporting to have less energy than what it actually has.
1st problem solved by simply turning off the wireless after im done with using it. No idea how could that be taking away so much energy, but it was. Somewhere during the period i was using my default rom i got used to have wireless always on, and my battery on the later times was going away faster than normal (i also like to listen to music on the phone). At the time i didnt correlate the 2 things, and i just put in my head that it probably was the battery dieing on me. It wasnt! The wireless (i suppose because of the Sync function also being on) has been draining my battery like mad between charges.
2nd problem persists. As you can see on the pic, those 2 spikes down correspond 2 diferent aproximatelly 1 GB file wireless transfers with Wifi File Browser app. This transfers (PC->Phone) make the phone CPU have to unzip the two 1GB files to the SD, so they are very CPU and SD card read/write intensive (i can force this battery drops with other instense battery use like playing a 3D game for example). The thing is if during that temporarly drop on the battery level measurement, the level hits 5%, the phone will shutdown. But to be honest, this problem is minor comparing to the 1st one.
There is one other minor problem with my battery, wich is the reading being inconsistent (drops 10%, then gains 15% then drops 5% again etc), but is this a problem at all?
I read a post of a guy that had made extensive testing to his battery cycles, providing loads of graph of battery levels (cant find link) . I didnt read through all of it, but i remember the guy saying something in the end like "Dont be too paranoid with your battery levels, as they arent accurate. Instead use your phone normally and you will gain an idea of how long will it last with certain types of usage"
By the way, he also said for people to just charge their battery whenever they could/wanted as it has no negative impact on battery life. I also read a bit of a paper on lithium-ion batteries stating the same, so no more forcing full-discharges for me!
One last thing! Deleting the batterystats file is as simple as disconnecting your phone from the charger.Why? because that file serves solely the purpose of suplying the UI with info of the battery drain usage on the current battery cycle.
http://www.xda-developers.com/android/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
And you can confirm this if you unplug your phone while looking at yout battery stats.
I hope this helps
PS: pls notice that it could have been not the wireless itself that causes the battery drain, but some service using the wireless. Finding this would require more extensive testing.

Update
Hello again
I just wanted to give an update on the situation since i noticed this post is linked from the Zoe Rom thread.
Two days ago i bought a new battery, an unbranded one (cost me 15€ here in Portugal). The shop had a legit LG battery for 37.50€ but i tought it wasnt worth the money. This battery has the same specs as the original, except it is 1300mAh compared to the 1500mAh of the original.
I dont have any battery related problem any more. Yesterday i woke up (100% battery), unplugged the phone, let the wireless on all morning, listened to 2-3 hours worth of tunes, browsed the web a bit, tested some messaging apps etc. Today i woke up, didnt charge during the night, and im sitting on 45% battery. Wish i had gotten a new battery sooner lol
With my old battery the phone wouldnt shutdown. It would always automatically restart. I had no ideia a malfunctioning battery could cause this.
I've have had similar problems with the battery on my GT540 with all cyanogenmods - 2.3.7, 4.0.4, 4.1.2. There were no such problems with original 2.1 I think it is the price for the newer versions, I can live with that, I don't have to buy new phone

[Q] Battery drain after calibration

I recently did a battery calibration on my HTC Leo with MIUI 2.7.27 and now it does last much shorter than before i did the calibration. Does anybody know why this is happening? Before i did it i could use it a full day without charging, but now i have to charge it twice every day. And that does not work too well since i still go to school. Besides, i just want to be able to use it a full day without charging. I calibrated it with the built-in MIUI battery calibration app.So it happened like this:
1. Fully charge it.
2. Click the ''Calibrate Battery'' button.
3. Fully drain it (I drained it until it indicated 7% because i use MAGLDR and we all know MAGLDR can't charge if the phone is turned off. If i would have drained it fully i wouldn't have been able to charge it again and it would be useless.)
4. Fully charge it.
And no improvement, it only got much worse. Someone, please help?

Nonetheless, i had the same problem too, what i did was i drained it to 2percent, power off, on, mgldr reset bat stats, and charged without break, and when the green light shows add another hour (i've read it somewhere in the threads).. As of now from 8AM to 6PM, moderate use still have 50percent using Team Blue Droid SENSE 3.5+ HTC ONE X TWEAKS TMO ROM. [AUGUST 4 2012] [CMR] " STOCK" Team Blue Droid SENSE 3.5+ HTC ONE X TWEAKS EU TMO
Hope this helps...
Thanks sundawg for the rom.

Thank you, but i am afraid that if i drain it to 2% that it won't be able to power up and boot again. If it is below 10% it drains battery extremely fast, and that would be a waste of a battery. (I've got another one lying around so it woulnd't be much of a problem though) Please advise me, should i do the same as you? By the way, i already noticed that if the green light shows it is not fully charged, but thanks for confirming i was right
Anyways, thank you for your help. I might give it a try when i am more sure about if it will power up with only 2% left.
P.S. Sorry for my english, it is not my native language
Battery drain is a common problem and a lot and I mean a lot has been written about it, just like roms where you have to make a trial and error method which suits you best, you also have to take into consideration battery quality sans its true capacity. In my case, I simply follow the dev's advise on battery tips. Since you have an extra battery, choose your best performing battery, and drain it to at least 5 percent and reset battery stats in cwm. Reboot it and charge without break, no sim , so that not to disturb it until the green notification kicks in, patiently add another hour just for keeps. Use it and sometimes it seems that there is no change but again patience is the key , Let it work out more until the charge settles and hopefully you get a better battery output and with correctly reported stats.
Finally, a rom that would not be too much demanding on power, one for daily use, devs post them if it is for daily use. Practically, only the apps you really need, a little eye candy, and simple games. Ciao!

One more question: How do i find out which battery performs the best? Simply by trying? Anyway, thank you for your advice, i'll try it for sure one of these days.
