20% Battery Shutdowns

Hi all.
As a desire user you're sure to understand what problem I'm talking about. I've tried calibrations and testing but still my phone turns off at 18-20% battery.
Im running cm7r2 hboot with Runnymede&Bliss mix Wmjan Sense 3.5 Rom.
Would anyone please help with some clear cut instructions?
With kind regards.

hello! when my phone turn off on 15%, i plug charger for a while (1-2 min) and turn on my phone. the battery shows 10%. i use them without charging untill he show me 1%. then i plug charger again, wait till it has 100% charging and unplug. after that no more problems - it's turn off on 1-2%.

Gonna test them later tonight.
One thing: when discharging phone from 10% ... Did you let the phone turn off at 1% and then recharged it to 100% on rebooting or the moment it said 1% you plugged in?

Method that is described here is the only working solution to calibrate battery. Deleting batterystats.bin does nothing (because they are deleted every time you plug off your charger when at full or near that)

I've said it before and Ill say it again. 20% shutdown is just a problem with battery calibration, its not a problem with capacity. Even though you phone shuts down at 20% the capacity is unchanged. The easiest solution to the problem is just to remember that 20% = 0% for you and live with it. Going through a lengthy fix is not worth it imo.

Fix is not lengthy. It can be done in one charge cycle plus some elementary math if you know how to read.

Cant remember where I read the original article (think it may have even been on XDA front page) but her is another one I found after 30 seconds of using the google machine, which has some very pretty graphs that may enlighten you.
http://78michel.unblog.fr/htc-desire-battery-shutdown-analysis/
And the conclusion is *drum roll please*
"As the discharge current is constant and almost identical in all tests, it is clear that the old batteries ( Part number xx-01M and xx-05M) have both lost about 15% of their initial capacity as they stop about 15% earlier.
Why the HTC Desire ( and may be some other smartphone ?) is not able to take into account such a capacity loss?"
You are very welcome.

I installed the kernel from the battery fix i think it was version 5. Run the battery calib app. Followed the instruction on the forum. And now my battery shutsdown on 0%. I'm using Seb's Runnymede AIO v6.1 Beta

If I might observe that you're very cocky for someone who failed in his statement and then linked to the article that proves that fail.
Indeed, article is true, up to the point we all know now, thanks to theGanymedes research, why battery percentage and capacity get misaligned, with wonderful guide how to fix it easily, au contrair to what you said.
You wrote this:

So I see two possible things at work:
a) lapsus linguae due to lack of punctuation, so even if you thought that the as it's age grows battery looses it's capacity (which is kinda self explanatory), it was not what you expressed.
b) you stated that as battery grows older, it's capacity remains unchanged, and if you can find a proof of that, you should be hired by some of battery manufacturers.
Either way, your rhetoric goes with situations where you are 100% right and can not get disproved, which you have been here. I strongly suggest not to pursue that path any longer here.

Well, making the long story short I decided not to calibrate the battery. It's a long process and terminates if the phone is charged while it is off.
I flashed a different rom and kernel. Getting 20-22hr battery (100%-20%)
My 80% battery provides me almost a full long day. So I'm happy with this. Btw thanks for the help folks.

Battery charging spikes?

Is it normal for the 1x to spike from around 90-95 per cent battery to full instantly, and is anyone else getting this?

Funny, I get this. I find the charging is really odd. Takes ages to go through a few percent, then jumps like 5% in about 5 mins. Anyway, all seems ok and discharge seems normal for me so I am not worried.
What I have noticed is that I get a much more even charge seemingly from my computers USB although of course it is a lot slower.
What charger are you using? I dont use the one the phone came with but I am using other HTC chargers. I doubt it makes a diff, but you never know.

My discharge rate is very strange. I can leave it on standby for ages and it will go down only a 1% or so. One minute after using it, the battery drops by a whole 5%-10%

I too get that, when in use can drop 5% right away, then some times 1%. Very strange.

One X to rule them all

One X battery fix?

Okay so I presume all of you one X power users have noticed a the horrible battery performance. I only got my one x yesterday and I'm already frustrated with the fact that i yet again have to carry my charger around with me. Is there a fix? I have root and custom recovery. So if there is a fix for this please someone let me know.m

Since I flashed the Revolution HD I got excellent battery performance. Without doing too much stuff (just calling and texting), battery remains > 50% at the end of the day. I would really recommend that rom.

I've just flashed it, going to see how it goes. But I would've expected HTC to bang a beast of a battery for the beast of a processor and massive screen its gotta run. Oh well, still early days, hopefully we'll see massive software improvements.

Not really, no. Personally I did not unlock device, neither root it, neither installed any fix. And I must say that I'm more happy with battery life than I was with my previous phone SGS2. More then 16 hours here with 4 accounts synchronization on, 3g/wifi on, and sometimes gps + music on (for Endomondo). I'm really happy with my One X.

ARHD Rom, auto-brightness, plain wallpaper, no haptic feedback, no roaming, managing syncing, and a few other tweaks will leave this devices battery life as one of the best.

Yep. Relax. I got 6 hours from first charge, 10 hours from second charge, 12 hours from third charge...
After over two weeks I'm now getting between 18 and 24 hours. Give it a couple of weeks before judging battery life.

I try to use as much as I can the first few days, and time it so that you have about 10-30% charge left when you reach home from work/school and then I let it charge overnight.

I know quite a lot of time was spent idle, but 60% after 7 and a half hours isn't too bad http://twitter.com/Dev_Meltus/status/194082996767309825/photo/1/large
I've not really had a problem with battery life so far.

how did u use it on those 7 hours? idling?

Have been seriously contemplating getting the One X.
My first choice had been the Galaxy S3..... but the One X seems the better choice.... I have had the iPhone 4 for almost 2 years, so now it's almost upgrade time If the Galaxy S3 had no physical home button I would be taking it.
Had been worried about the battery life of the one x but after reading these and a few others it seems worth it and it's available in black (dark grey but darker than S3 metallic blue)
I Just hope I don't have issues with app incompatibility for the apps I use on iPhone.

With normal usgae, I've got more than 10 hours after one charge. Not so happy with it but it's good enough for me.

have you got yourself the One X? if so, how is it compared with your previous phone?
i also want to swap my iphone 4 with One X and looking for different experiences especially with the battery life

I've turned everything off and left my phone on idle, my battery issue has persisted for over 6 months now (I bought it in Singapore on release day). With screen on min brightness, static wallpaper, most apps off, my battery drains fully within 6 hours. If I actually do anything with it like make phonecalls, it drains in hours. The battery phone is constantly hot, when on charge It's almost too hot to hold. If while on charge (AC) I use it to make a call, it complains that it's not receiving enough power. Should I look to get a replacement from HTC? I'm still using stock rom so it should be covered under warranty?

Sounds like the htc amaze battery overheat..
Also get gsam battery app.. it will tell you what apps are using what % of battery.
I also use advanced task manager from play store.. it proved to me how much gmaps Facebook and other bloat was ALWAYS RUNNING!.. I got root and froze it all with big improvements
Some of us who htc amaze w no warranty bought a new battery and that fixed it

Aside from your time travel/exaggeration, I suggest better battery stats, finding out what is causing wake lock, and killing.it.
Your phone is fine, but you have some crapware on it.

Battery drainage on HOX

My battery on the One X I think is bad, when I check facebook or Twitter on WiFi, it drains 1% every minute and it annoys me. Playing simple games also drains 1% every minute...really annoying. Is there a problem please help?

It happens to me as well, but only if I turn on WiFi and let the phone use it´s online services.
Hoping that the Jelly Bean update with Sense 4+ brings some kind of optimization.
I have my HOX configured pretty much like my SGS3 and my S3 lasts 20, 30% longer and about 7ºC colder.

Same here, kinda want to change my phone again if HTC doesnt fix this problem.

do a battery calibration, app like this works https://play.google.com/store/apps/details?id=com.nema.batterycalibration&feature=search_result
before the app 1 day usage = 60% of power left
after = 85% left
HTC made too much of the safty triggers for the battery if u use it lightly every day its minimizing side effects by making new one (less charge)

How long have you had your One X, OP? It takes several full charge cycles for the battery to calibrate, it's one thing about One X that's weird. I remember being completely disheartened with battery life when I first got mine - and it was horrible, pretty much like you've described it, 1% every minute or so - but only kept it because my mobile operator wouldn't replace it before making sure there is a hardware malfunction, which could have taken weeks, and I was impatient. Then I learned from xda that this slow calibration phenomenon is a thing with this phone.

I hope you're right svucinic811 I'm really getting worried here

I am wondering what a good rate of discharge is cos if i leave it on standby overnight it went from 99% to 79% in about 8.5 hours. personally i think it should have been 99% to 89% in 8.5hrs but anyways...

It should only discharge at most a few percent. Check your wakelocks with BetterBatteryStats.

Will this work even without rooting my phone? I'm running on Stock Sense 4.1, but this seems like it would help a lot.
As well, if you (for a couple days) go without charging your phone in the middle of the day and let it run down until you charge it again I think you will see some results in the battery life. My battery would die everyday before school ended for me (Wake up at 7:00 AM, Phone dead by 5:00 PM). Unless it was just a placebo affect for me, its worth a try.

Does anyone else has this problem where, yes the battery drains fast, but takes forever to get charged to 100% ? FYI, I'm using the real charger, not via PC~USB

how do i calibrate betterbatterystats?

What's forever? 3 hours is about normal, unless you're heavily using it.

You don't have to calibrate Better Battery Stats. Just charge it up to full, then wait for it to happen again. Open it up, choose Since unplugged (obviously you should not have plugged it in at any point of time since the full charge), then take a screen shot of Kernel Wakelock, Partial Wakelocks and Process.
@Rohin, USB Cable quality plays a big part as well. A cheap rubbish USB cable even connected to the wall socket charger can only charge at 300+mAh, while a good one can charge up to about 750+mAh. About 85%-90%, charging usually slows down to about 200-300mAh, then slows down even more as it approaches 100%.

Wipe ur battery stats, drain ur battery then charge uninterrupted till its full, drain and charge again so that max and min battery levels are well calibrated. A battery app like battery doctor will help keep ur battery in giid shape.
Sent from my HTC One X using xda premium

Perhaps is there another reason. When you install a new rom, you must wait several cycles of charge/discharge to have a good battery life.
So, interrupt his charging cycle isn't the best way for battery life. And yes, you must wipe your battery stats to.

Now my battery died, when i plug charger, sometimes led blink 2 times with red light, and it's over. I will replace it. I pray for battery issue, not motherboard. What do you think about this problem?

I had the same issue under Sense 5 roms.
With the phone on and charging I never reached more than 60% of battery even using battery optimizer.
The solution for me has been back to a 4.2 AOSP Rom (ICJ in my case) and a couple of cycles again my battery works as usual.
I tried again with a S5 rom and the issues are back, so I have to use no Sense 5 roms if I want my battery right.
You can also try to charge in Recovery, that worked for me, to wake the bootloader.
Hope this would be useful for you.
Cheers.
PD. Sorry for my english

Have you tried a stock sense 5.0 rom?

This week i found something that seemed to be a issue like the one reported here. My phone goes without battery before i got to sleep. I got my phone to charge on the Wall charger (HTC OEM). When i woke up i figured out that my battery only charged up to 15% (Froze at 15%)
It is the second time this has happened since the Sense 5 update (OTA Update).
Never happened before.
