An odd problem

Got a Desire Z, but the battery seems to go down too fast, even when not in use. Same thing when the phone is off also.
I get around 5-7 hours of the phone being on with about 15mins use and the battery is dead.
When the phone is off, I get about 8 hours.
I know its not the battery as I've tried a few. Ive also tried a few ROMs aswel as stock ROMs.
Any ideas on how I could fix this?
Thanks

Every time you flash a new ROM you're wiping the battery stats and it takes the OS a few days to re-learn your battery. Wipe the stats manually and give it a few days.

Yea but how long do you wait before you end up reflashing or wiping again?

Around 3 days.

Have you checked to make sure you don't have some sort of errant app that's causing your battery to run down?

x2 this happens a lot especially going from ROM to ROM. The built in function works ok, but I generally use Android booster to narrow down errant specific apps even built in Android apps like sync. It helped me go from 15 or so hours to 24+ especially if you use autostarts and TB to freeze or prevent from startup

3 ish days is probably not enough for Android to learn the battery levels properly. It takes a few charge cycles to get the values right. I wouldn't have thought its good to wipe battery stats constantly.
With the Touch Pro 2, you could force a learn by discharging it completely until it doesn't power on the firmware any more, pull the battery for a minute, charge overnight while powered off, pull the battery again for a minute then power on. This updates the values in the firmware too.
I have read it works with the Desire Z too, and I've tried it after a ROM flash just to wipe. Obviously, while you can still get into recovery, wipe battery stats prior to this.
Disclaimer: Do this once only, its very bad for Li-ion batteries to repeat this. Do this at your own risk.
If that don't work:
If it does it in airplane mode then its probably an app.
Make sure you flash something like a rooted stock ROM and make doubly sure you wipe everything before first boot. Data / Cache / Dalvic cache etc.
If you haven't installed any apps and it still does it, RMA the phone for repair / replacement.
Hope that helps!

Thanks for all the help above. Will try for a few more
Days.
Though the battery even dies when the phone is off.

Well, Ive still got the same problem. Ive realised aswel, when the battery dies and I go to charge it up the orange led flashes for around 5-10 minutes and then turns a solid orange.
Same thing happens with a replacement battery.
Im guessing its probably a hardware fault

I've had the orange led flashing before after a completely flat battery. Its probably something to do with a dangerously low voltage from the battery. Its extremely bad for Li batteries to get very low..

Have no idea. Must be sg wrong with the HW, get it to a service station or ask for replacement where you have bought it. Mine goes for days. (bought in Austria, factory unlocked, Android 2.3.3)

My battery is going bonkers!! Now its Smoking!!

I have no clue what is going on with my phone, but my battery is doing weird stuff.
1. Sometimes it shows its charging when its not.
2. I get a consistent low battery notification at 15%
3. And it get these weird power glitches.
Anyway if anyone could help. That word be great but I'm about to just call vzw and get a new phone.

!!!!!!UPDATE!!!
I called Verizon on Monday who told me it was a known issue and a software update would resolve it. However I told them to send me a replacement anyway.
Now today..I plugged the phone into my USB cable connected to my computer and it started smoking!! I swear I zapped something. It still works, but now its all weird. I going to have to use the wireless process of getting it back to stock and locked..so we will see how it goes.

We need more information.. did you do anything on your phone that might have done this? Can you confirm that battery is fine?

Not that I know of, its running CM10 Euroskank.
I also noticed that when I plug it in to the charger it takes about 10 seconds for it to recognize that I plugged it in and start charging.

I had a similar issue on the GSM 4.1.1 stock ROM where the battery voltage was being misreported (using Battery Monitor Widget to check values). Sometimes the voltage didn't decrease with use; sometimes it even increased without being charged - your battery graph seems to show this too.
This problem developed literally overnight and didn't rectify itself over multiple charge/discharge cycles. I changed ROMs to see what would happen and to my relief there were no further problems.
As an option you could try clearing the battery stats in recovery.
Given that a few people in this forum have had sudden battery weirdness, and that a fresh ROM fixed it for me, I suspect there's a rare software bug at work here...

-1 on the clearing of battery stats. It has absolutely nothing to do with it. He'd get the exact same results by changing his ringtone or something else that's totally irrelevant.
Battery stats has nothing to do with the reported percentage of battery. It cannot cause power problems. And it will not affect battery life.
How is it that the wives' tale of clearing battery stats still persists despite the fact that a Google engineer has debunked the myth and that debunking has received wide publicity within the android community?

I had a very similar problem with galaxy s2. My symptoms were that it thought it was charging when it wasn't, it thought it was usb connected when it wasn't, and my battery graph would just show one long spikey graph for as long as the phone was on. I posted it up and someone clever identified the problem straight away; a short in the usb charging area.
Have you ever spilt any liquid near the usb charging port? It's a replaceable part and I'm sure it's available from the usual place (ie. Ebay).

Also, the text file that has the "battery stats" is erased when you reboot, which is the same as manually deleting it with CWM or whatever.

Battery not charging past 82%! Help!

Hi,
I bought my GSM galaxy nexus about 2 months back. I unlocked bootloader, rooted and installed stock JB, with franco.kernel. It worked fine for maybe a month. Then, charging the battery started maxing out at lower than 100%. Now, it does not ever charge beyond 82-83%. (in battery settings, it shows "82% - Not Charging" even with the stock chrger plugged in. I also charged using USb, the iPhone adapter, and another samsung charger.
I put this 82% charged battery in my friends GNex, and it showed 96% on his phone. It even charged to 100% without any hassles.
I put his phone's battery in my nexus. On his phone, it read 60%, on mine it showed 25%.
so, my phone's battery reading is off by almost 20-30%.
i wiped the phone FULLY, installed CM10, installed stock ROM, stock kernel, but nothing seemed to change this behaviour.
Any ideas which might help me, or do i send it to google? (which will be a lot of trouble since i dont live in the US).
Thanks.

Charge it fully ( in your case to 82%). Then boot into cwm recovery and try to clear the battery stats.

Battery stats has absolutely nothing to do with it. Charging his phone at only 4pm while having it gave down on an espresso colored end table would yield the exact same result.
No info related to battery charge is contained in that file. It is only a list of apps that have run on battery. Nothing more. Furthermore, the os periodically purges the file on its own.

yes, i believe it does (It still gets me through the day, like before). I think it stops charging because the battery gives a feedback of being full, just dunno why the phone thinks its at that low percentage..
could juice defender have something to do with it?

Nope, Juice Defender only turns radios off and on. Nothing to do with how phone reads the battery %
May I ask what you have done to fix it?

I am unable to anything that can fix it. I have tried wiping battery stats (knowing it's useless), drained my battery and recharged, full wiped etc.
The reason i'm asking about juice defender is that i switched JD on some time back (on extreme mode). The battery was at 66% when i unplugged it and put JD on.
Since then, the battery reading has come UP to 70% (no charger connected, and it even shows discharging in the battery settings page).
I'm thinking i'll charge to whatever level it allows, then leave it for a day with juice defender on, maybe it'll go up to 100%.

Sorry that I cannot help you, but I've seen a lot of threads about this. I think you should search for them and see if there's an answer. I think that's the best choice until somebody comes up with something

silly question.. have you tried another battery? the problem could be the battery itself.

You have obviously a reading problem not a battery problem. Something got messed up somewhere. I recommend wipe clean your phone and bring it back to stock. If it works, start toying with it again, if not you are ready for warranty exchange

If you already flashed back the stock kernel and that doesn't fix it, I'd say your gnex has a hw issue.

Thanks for the replies.
1. As i said, i put my battery in another Gnex, reading was much higher, and charged to 100%. I put my friends battery (at 60% on his GNex) in my phone, it showed 25%. Not a battery issue, i believe..
2. I wiped FULLY (including system, data, cache, dalvik, battery stats. everything except my storage) and went back to a rooted stock JB rom and kernel. no change. so i switched back to CM10.
So.. i guess hardware issues?
Also, could you help me out by giving a link with this problem elsewhere, i cant seem to find one.. i'll keep searching though. Thanks..

I know this is over a month old but I was wondering if anything has changed on the status of your Nexus. I have been having similar problems, only charges to a max of 63% though then dies in under 5 hours. I have tried a couple things you listed like going back to stock ROM, trying other batteries, pulled SIM card and battery out and just left it on a desk for 5 hours.
Did you end up having to send it back to Samsung?

I had already faced same problem in my samsung grand prime device

I had the same problem with my Meizu (!?) phone. The solution was to turn the phone off and charge it. It would pretty quickly go over that fixed % and to 100% full.

How can you troubleshoot certain parts of your phone?

Hi All,
So recently I have been having problems with my battery life. It's not lasting as long as it should. However, I do not know whether or not its my data cable, the device that plugs into the wall, my battery, or the charging port in my phone.
I got my phone from best buy, but it was more than 30 days ago, and I have no insurance on it, so I cannot get a replacement without sending it away for at least $100.
Any tips?

Well what battery life are you getting? Get into the Phone settings and then battery settings and post a snapshot of the graph here. Additionally you can also install Batterystat it will give you a full analysis of what's using up your battery power.

I think I may have narrowed it down to the battery itself? I have some battery apps that tell me the health is "good," but what does that really mean? My charging cable is iffy, because sometimes it works perfectly, charging to 100 just fine. However, other times it charges 20 percent in 9 hours. When I used my friend's Note II charger, it worked perfectly every-time. But the fact of the matter is, when my phone does charge to 100 from my cable, I still get not the best battery life, which leads me to believe it's my battery's fault. I am going to test out charging my phone to 100% with my friend's cable tonight, and see what happens tomorrow. I will also get batterystat and report back.
Also, this may be important. When I first got my phone, battery life was AMAZING, really quite astounding. It's just kind of dropped down, like a slope. Not a sudden, dramatic drop, but incrementally.
As for the battery info below, here is what went on today. I unplugged my phone from 100% at around 7am. It is now 6pm. Today, my phone was barely used, just sitting in my pocket with wi-fi on. When I did use it, I sent two very quick emails, played scramble with friends for about 45 minutes total, took a few photos, listened to music from the music player for about 15 minutes, and that is really all I did. I feel that my percentage should be much higher than what it is listed as.

Here's mine as you can see I'm getting almost twice your battery life. I have a few apps that i use everyday which are basically whatsapp, xda, chrome. I don't have many apps that would wake the phone constantly and if there is then I disable them from starting up when the phone is not in use. The best tool you can use for something like this would be rom toolbox pro. It's multiple system tools in one and it works great. I'm currently on Omega V10 with perseus kernel. Also I don't connect to wifi much and network here is weak and on 2G but even though I still get this battery life. In areas with good signal I get more battery life. Also I've dropped my phone twice with impact points on the corner, and just minor scuffs but that didn't effect the phones performance or battery life so I doubt it has affected yours.

Also I've overclocked, my processor to 1.8ghz and undervolted between - 50 and -100. So i get minimal power wastage from heat build up. Also you can set a black wall paper with a dark theme.

Unfortunately, I am not rooted, and haven't planned on doing so ever. Is there anything else I can do to fix my problem? I did download batterystats, and am waiting a few days though to see what it tells me.
Also, I used a different charger just to see what would happen today, and even though its been off the charger for 2 hours, it's already down to 94 percent. So I am thinking that there is either something wrong with the battery, the charging port, or could there be a bug in the phone's software?
I am thinking of getting a new battery, and seeing if that fixes my problem. I'm just so irritated because battery life used to be amazing, and I don't know what happened.

Maybe try a factory reset. Maybe something else has been using your battery.

That's what I was thinking. I will probably do that and report back, before going out and buying a battery or something. Is it possible that, although not reported in the battery info, that an app could be rogue or something or taking up battery? I don't want to do a factory reset and redownload a bad app.

Update: I tried a factory reset. It seems to either be worse or just the same. It's been an hour and has dropped to 97 percent, but I have made a couple of phone calls. But compared to before I did a factory reset, it dropped to 96 percent in two hours while not doing anything.

Keep your phone on charging over night.
Then let it drain to zero no matter what.
Do this 3 to 4 times and then
Leave it for charging overnight.
Then while it is already charging use battery calibration.

Quick Update:
I did another factory reset after I said the initial one didn't help. It looks like it may have helped, although I still have not gotten the battery life I used to have.
I found an application here called betterybatterystats, and have downloaded that. I will use my phone throughout today, and will post sceenshots.
If need be, I will take your advice about charging and draining and charging, and then do the battery calibration.

Here are my most reset battery stats. Screenshots are from the battery setting area, and betterbatterystats
Maybe I am just being paranoid and nothing is wrong? I can't make any sense out of these readings, but I hope someone else can.

first of all change you cable if you are having that kind of issues. Mine in my galaxy ace was having that problem, it was like connect/disconnect without any reason and it didnt charged my phone at all. I noticed it when it was too late, the continous on/off kill my battery. When I say kill i mean it just lasts 15 min in 3g with screen on and it happened to me in 2 official batteries.
good luck!

[Q] Can a battery go bad this fast?

Hi all,
My SGS3 suddenly since last night has not been able to recharge, battery critically low. I have tried a few chargers, and rebooted several times.
Can a battery go bad this fast, because looks like it was charging and running fine the day before.

Have you tried loading a stock ROM on there just to be sure it's not software causing harm to your battery? Not sure if your provider will warranty your battery if it is indeed your battery.
Good luck!

Hi, thanks for your response
It actually is stock rom, sorry forgot to mention it. It is rooted, but I never replaced the rom, just put in CWM recovery. I just moved from rogers to virgin mobile last night, just changed sim card. But the multiple reboots killed a maybe already weak battery?
Thanks

You should download and install better battery stats, it may help you find out if its being kept awake and draining quickly that way

Thanks for your response, necrowakker.
I guess that I forgot to mention as well that the phone was shut off during a recharge, and upon powering up, it still it complaining to plug it into a wall charger.
Like it was never plugged in.
Heeter

When you rooted your phone was the kernel changed? .. I've had experience with some custom kernels not reading the battery correctly when off, and only after switching it on it still States its low til a little while later it actually looks like its charging .. ( like the battery level goes up over time) while being off the charger.
If thats not the case, try charging your phone again, but while its on after you know its definitely discharged and not just a ROM memory issue. If you turn it off to keep from getting calls during the night switch on airplane mode to keep that from happening. And check if your battery does on fact charge correctly. ...
After 3 full charges and discharges your battery still gives you bother. Then you can either look into what process it was when you rooted,
if it did change anything more than just giving you more access, or see about a hardware replacement, if it is under warranty, and you can take the flash counter back down to zero (if it counted up) and unroot it.
Also using unsupported chargers over the recommended charge rate for your phone, could have done it damage but that's a long shot with today's safety measures on phones.
Edit:
Don't forget to install better battery stats too, just for checking and reporting. Stable ROMs should be able to handle over 300 hours up time before needing a reboot. So using airplane mode should not bother your phone too much
Sent from my Pengus77 powered LG-P990 using xda app-developers app

Thanks for all that info.
The phone has been rooted for at least 6 months now. It has been running very good until this morning. No kernel was changed for the rooting. I just wanted titanium backup to work.
I am still presuming that maybe the battery was weak, and when I was changing out the sim card of the service providers, I did reboot about 15 - 20 times to try to get all the services running, maybe that was enough to kill a battery.
Heeter

I've don't some silly **** with powering and charging and pulling batteries for every reason, I can't see Samsung giving you a bad battery if its worked fine for 6 months, you'd probably know within the first 6 weeks if it was faulty. ...
It may easily be a software memory issue with the battery that's confused it. If you are using cwm as a recovery it may have the erase battery stats option on it, if so give it go,
charge your battery to 100, allow it to drop to zero, or til it shuts down, plug in, power it on allow to boot, and leave to charge to 100,
once that full discharge and recharge is done, your battery has its full stats. If it gives you hassle after this point, think about buying a registered Samsung replacement for your phone.
