Battery does'nt last an hour

Hi;
My stock battery started to blow up(not actually blow up, but like grew a stomach) and so i changed it with one from a cornershop. The new battery doesnt last an hour so i decided to get one from amazon. This one would only last 1-2 hours.
whats going on?? i would go outwith a full battery, surf the net or read a book while on the train normally a 23 min ride and the battery would be halfway gone and less than 45% left.
i have to go out with both batteries fully charged so i change them when the other runs out. i realy like my nexus one is this a hardware issue? any thoughts?

Have you tried calibrating your battery?

i will try that, just doesn't seem to be normal that the battery would run out so fast though.
if you could recommend an app u know that would be great too

Obviously, you have a rather large problem that an app wont simply fix. If you have flashed a custom recovery, such as AmonRA, look for the Wipe option and see if you can wipe battery stats. Then, shut the phone off, charge for a while, maybe overnight. Then boot up in the morning and pull the charger out when the lockscreen/homescreen appears. If battery is still **** try another ROM or kernel. All else = new phone.

sorry for the late reply.
The wipe battery stats has def helped. battery last an hour longer, not much but i would recommend this trick.
still doesnt help me that much but thats probably due to it being a hardware issue.
thanks for the help though, props

I think your battery may very well be dead. Buy a new battery from ebay is what i would recommend

[Q] Battery Calibration error?

Hey guys,
For some reason my phone keeps battery-% on some numbers way too long (compared with the day before). I was on 85%, and put it on the charger. 20 minutes later it was on 98%, but another 20 minutes later it was still on 98%. Some time later I found it at 99% and unplugged but the % immediately went down to 98%. I left it overnight to charge 'til 100%. Now the battery-% takes way too long to go down and way too long to charge again.
Suggestions on how to solve this?

I would suggest factory reset.Since there is no more Eco Controller(or how it was called) to reset :/...

I'm now using an app to recalibrate my phone. Does this sound logical? 4203mV - 100% and 4098mV - 95%?

Eco controller still exist in 4.3. Clean data, stop it and restart phone. I have also wiped battery info in cwm twice and everything works great.

I'm on 4.1.2 (see signature). I did the ECO trick, but I can't wipe battery stats because somehow I can't find it in my CWM recovery

Yea, i know. I wrote 4.3 cause thought UltraWelfare meant it. Unfortunately i have got Philz cwm for a while and there is no such a function as well but i'm sure in cwm touch it exist.

Why does this happen?! Battery annoyance.

Just when I think I've got it all setup nicely...
Latest AOSIP rom with Hellscore kernel, stock settings greenify, full discharge and recharge, all seemed so good....
And then boom. Go to reboot to recovery and I get the little empty battery icon upon reboot - but I was at around 40%?!
I use the battery calibration app, for what it's worth knowing the debate about the battery stats file. I've done the bootloader logs 'trick' and still I get a random occurrence like this?!
Anyone else been plagued with this randomly happening to them?

There are so many reasons it can happen. on thing id recommend is install ampere form play. Using this you should be able to monitor the voltage of the battery and at least know that it is operating within the correct range. if your 0% voltage is too high, it could rule some stuff out.

Cool. Just periodically check the app and jot down the percentage and voltage. keep doing that until its ready to shut down. preferably a reading every 10-15% if you can but really important is to try and capture readings just before and after any drop off you may see.

Perfect thanks for the advice, I've got it installed and now juts doing a full charge.
Following that drop out, the device then reported 7% battery so I let that go flat and now fully recharging.
If it's the case that there is something going on here, how can the issue be corrected? Does Ampere help configure reported VS actual readings, or does it purely show what's being drained?

Its worth getting a voltage reading now too then, to see if it is as low as expected. As for solution, we need a root cause first.

Ok here is my first screen. I'd browsed Facebook (web version) and watched a video or 2, battery dropped to 97% soon after.

Yep. Just keep going. Every 10% is fine. No more than that. Actual battery charge is voltage so we just want to see if there are any conflicting data sets later on

It just did it again!!?
I had even doing the Ampere monitoring but didn't go all the way down. But today I just experienced the random drop out again. Strangely when I booted back up, it was as if the cache had been wiped as the Android Optimising app screen came on.

This was from the other day though, if this helps?

The other day did it seem to deplete normally? I'm around 20%/right now and see similar voltage to you.
Sometimes my phone used to crash and when it booted up I had this graph / drainage issue. It's as if it goes into some manic sleep that kills everything. What you've got here seems similar. I don't think there's an issue with the battery cycle itself.
I'd be tempted to do a factory reset and start clean to be honest.

Is the back of your N6 lifting away from the frame? I had this issue too and ended up doing a RMA because the battery was bulging.

Weird and annoying isn't it!
I've recently flashed this new rom and so has been a fresh start so I'm kind of at a loss as to what to try next.

Just took off my case and checked and all seems normal, back doesn't appear to be coming away and seems to be ok.
It's times like this I miss my good old Note 3, never had a battery life like it for its flat lining ability!! (see attached)

If it were the battery capacity due to bloating, I would expect to see the Voltage value to be wrong
Go back to stock and run it with no restored apps / data. If it still happens RMA

Your battery calibration is messed up. It happens.
DO NOT waste your time with "battery calibration app" -- there is NO software you can install and run from Android that will have ANY impact AT ALL on the battery calibration. All those "battery calibration" programs do, is delete the battery stats file, and all the battery stats file does, is store a log of what programs are responsible for how much resource utilization -- nothing at all to do with calibration.
Battery calibration reset is done through the BOOTLOADER.
Reboot your phone to bootloader. Scroll to "bootloader logs". Press and hold power button until the phone shuts down.
And that is all there is to it.

Thanks for the reply.
Unfortunately, I have tried this many times and so there must be more to it than this. On my latest rom, I had wiped phone and clean flashed whilst phone was connected and at 100%. Therefore a new clean install whilst phone was at 100%. I cleaned that stats (for what it was worth) and also did the bootloader logs trick. I would have thought that would have solved the issue, but as reported it still happened.

Your calibration is fine because the % matches up to the voltage, which is all calibration matches.

It's hard to say. It seems like the system may be crashing or something at that time and causing an inordinate drain. Thats what mine used to do sometimes.

hi is this normal?

Hi is this normal if not how can I fix it surely android is shouldn't be at the top of the list

You have to factory reset the phone. That also happened to me a while back, intense battery draining while the phone is idle. It solved the problem

Its normal. On my phone battery diagram looks same. After charge to 90~100% in few hours ( avrage 3 h on screen) phone yelling for power. I think the problem is in Android, something similar to first 5.0.

pathetic battery

I am on Repulsa rom with mad max kernel. And the battery life is pathetic. From 100 to 20% there is no problem but as soon the battery goes below 20% it will literally go to zero in 10 sec and will shut down. It happens 9/10 times.. As soon as it goes below 20% it will shut down in few seconds.. This is not rom or kernel issue because this has happened with different rom and Kernel too.. If anyone can help it would be of great help..

Battery is badDegraded. common thing with phone batteries. Gotta get the battery replaced

I dont have that much knowledge but i am unrooted and happened to me serveral times as my battery shut downs in 13 percents. I looked for a solution and my issue resolved. Hope if it can help you
Maybe its calibration issue
Maybe your phone thinks 20% is 0
Try using fully discharge your battery until it shutsdown then go to recovery mode and waste the juice until it turn off and dont even boot into recovery. Then charge full with power off and again discharge to 0. Again to 100 and see if problem solves.
If not then maybe issue is with battery

I'm getting 5-7 hours here depending on the usage but to be sure go back to stock room for 5 days and check the SOT BY THE WAY I'm on Lightrom with the mad Max kernel

My phone used to be like this... so annoyed.
I tried everything but no result: using battery calibrate apps or methods, flashing stock rom, reinstalling TWRP,...
I am quite sure when your phone is at 20%-, you can't see battery % in TWRP mode :V.
I think the cause is TWRP ( data can't mount )
Here is what HAPPENED to my phone )
I flashed ECHO rom and my phone got bootloop..."Only official binaries ...."
Fine....too easy to fix... I flashed my stock rom and ta da... My phone's battery was Fixed :V
So ...you can consider bootloop your phone to fix the problem ))) Then wait 7 days without restarting your phone... reinstall TWRP ( "NOUGAT" or "OREO" ). And when you download dm-ver... zip to install TWRP, look carefully for LATEST version "LATEST". And dont update your TWRP or use themes for TWRP (Old is gold, simple is perfection :v , fuctional is too enough)
GOOD LUCK

Why wait 7 days with no reboot? Not needed if it's to make the OEM toggle visible...just wait 7 days or use the date-change workaround. Reboots affect the uptime timer but not the server-side OEM unlock timer.

Happened to me lately on stock, never rooted. Try turning off quick charge and use normal method instead for a few cycles. Maybe test on stock firmware just to be safe. If no improvement it might be a degrading battery.

I am thinking to factory reset the phone to see if the problem is solved.. N try the solutions offered ie calibration, quick charge off

Sounds good, just be careful with calibration...fully charging or discharging the battery reduces it's overall lifespan. Don't do it too often.

I did factory reset including internal storage wipe and calibration Bt still the problem exists.. Now the battery will go down to 15 then directly 14,12,10,5 in seconds even if I connect charger at 15 it will go down till 3%..

Yeah, it can be possible to degrade the battery that quickly.
It usually happens when you let your phone go under 20% frequently or let it die completely before charging it again.
I usually do the lowest 25-30% and the 80+% charge daily, then finally use it all the way to 20% before going to sleep, put it on a slow charger, and by next morning its at 100% without keeping it charged 100% all night (which can also degrade the battery, just a lot slower than discharging it completely.)

I have had my phone a week before it came out and my battery is awesome. It lasts me all day everyday. Best phone I have ever had.
