I charged my Samsung extended battery to full then reset the battery stats but my battery reporting is still terrible after 3 days. As soon as I unplug it from the charger it is automatically at 98% and drops quite rapidly.(~3% every 5 minutes of active use)
Would allowing the battery discharge to automatic shutoff alleviate this problem? That hasn't happened naturally yet
That can be normal behaviour. Mine does it sometimes too. 95% and up on any phone will be that accurate. As for your drainage problems, your phine is doing something heavy duty in the background. And/or you are running full brightness. I am getting 4.5 screen time on average. I was able to get over 5 hours this weekend. For me to get 3% every five minutes i have to be playing a game or been downloading a large file over cellular data.

Seems like you either have a bad device or you have an app or two that is killing you. Something that gets push notifications for example, like a messenger or something similar

I have been experiencing this as well, my stock 1850mA battery seems to outlast my extended 2100mA battery by about 20%. Has anyone else seen this behavior? I have been thinking that maybe I got a bad battery.

I have just installed Battery Monitor Widget as recommended in a battery related thread in this forum, and it is showing my extended battery as having 1750mAH. I don't know why and I'm not sure what to do to fix it, and my battery life is pretty awful.

Battery Monitor Widget allows you to manually change the battery capacity.
Touch the gear symbol, select ""Monitoring", then "Battery capacity". Enter 2100 if you have the CDMA extended battery.
Yes, I saw this - but if it's getting the capacity from the phone, and the phone is reporting 1750, isn't something wrong? Doesn't that mean it will stop charging the phone prematurely because it thinks it is at max capacity?
In fact, I just remembered the stock battery is 1850 mAH so I have no idea where the 1750 is coming from...
Thanks for your reply.

its coming from the GSM version because it has a 1750 mAh battery.
battery monitor widget is not pulling from the chip inside the battery, it is just guessing your capacity because it knows its a galaxy nexus. hence you have to manually enter your correct capacity into battery monitor widget yourself.
also remember this fuel gauge is not capable of giving current readings. so battery monitor widget is guesstimating current based on extrapolating the drop in your percentage among other tricks the developer uses.
Thank you very much for your reply. It makes sense what you're saying, I took the setting in BMW literally as it states:
"Override capacity provided by phone"
Thanks to both of you for the help. Now I still need to find out why my battery life is sooooo bad...

This does ONE thing. and ONE thing only.
It holds the history for the battery information screen on the phone.
eg - "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
End of story.
the battery level and charging and control and everything else is controlled elsewhere.

Hi,
On my One-X battery meter is completely inaccurate. Sometimes it sits for hours on one value (e.g. 90%) and then suddenly drops (with no CPU/data activity whatsoever) to for example 80%. This results with very jerky battery use graph (attached mine). I am on 1.29.401.7 and done multiple full discharge/charge cycles, but it does not make any difference.
I have never seen such bad battery meter behavior on any other Andoid phone. Have you got similar problem?
I have the exact same problem actually.
Same here. It's as if it doesn't update the battery meter when it's in sleep (fifth core running). I suspect it's because of the T3 architecture and power management. As soon as you wake it, after maybe a minute, it updates the battery status...
Mines does it. Can sit on a %age for an age then with little use it will plummet.
@Op,
No I didn't notice such a problem on a unrooted One X and with no modifications running the latest OTA update 1.29.401.11.
Did you play with battery apps or did you modify something yourself which could cause this issue? Did you investigate what could cause it?
How long do you have your device, did you install apps? Can you provide more info about it maybe? Do you softreset your device?
Did the problem exist when you bought the device?
Thanks.
So it must be general problem then. It happens to me not only in sleep mode, but when browsing the web, etc.
I think these sudden percentage jumps and meter inaccuracy also contribute to all these battery life complains from various people. I was personally shocked when after a few minutes of web browsing battery dropped instantly from 30 to 20%. It looks like crappy battery, but in fact seems to be just dodgy meter...

I have got the phone for almost a week now and I am pretty sure this problem has been there from the very begining. I initially though this is because a couple of full charge / discharge cycles are required to calibrate the meter, but it did not make any difference. My phone is not unlocked, no mods or battery apps. I did not try soft reset though.
It looks to me that meter is somehow not updating during the sleep. When device wakes from sleep, after a couple of minutes value drops significantly. This problem is probably a reason for various false claims that One X does not consume a single percent of battery during the overnight sleep.
Yeah, i have the same thing. Sometimes my battery drops about 2 or 3 percent at once, sometimes 10 percent...pretty annoying.
Thanks for your reply.
I'm new to Android but I do have some Windows Mobile experience.
It's weird to me seeing people having such problems because I realy don't experience it.
My battery meter is constant, also after a night sleep.
Maybe it's because I use my device different as others I don't know, it's strange to see all these reports in XDA forum as the One X to my opinion is a very cool device.
Maybe you could try some battery percentage apps and see if it realy is that insufficient?

I used your excellent ROMs on my HD2 in dark WM6.5 ages . I am glad to see you here with One X!
I installed Battery Meter Widget and (if the readings are correct), my One X consumes about 10-15mA during the sleep with Wifi and 3G on. I will keep an eye on the percentage.
Don't get me wrong - besides of erratic GPS and dodgy battery/power management problems, I really love this device.
I really wished that international One X version was based on S4 SoC (superb GPS with GLONASS and great power management as S4 is a 28nm chip). It is such a shame that dodgy Tegra 3 ruins this excellent device...
Hello, maybe this behaviour is only due to the voltage sampling/display ...
Someone here says the native battery app was only at 5% precision at display
and it looks like it updates in long time samples too ( 5 minutes ? ) ...
Knowing that Li-Ion goes from 3600 mV ( 0% ) to 4200 mV ( 100% ),
it means 600 mV of voltage variation from empty to full, with 1 mV precision.
So 1 millivolt is 0.2% of battery charge.
The display should be really more precise if all voltage precision was used.

looking at that screenshot you have posted the sudden drops appear to be perfectly aligned to the 'screen on' or 'awake' periods so the most likely (and obvious) cause is that using the phone causes most battery use. I have seen this with many phones, I think its normal. Being in standby doesnt use much power at all but lighting the massive 4.7" screen and running a quad core processor does, so when you use the phone it uses loads more juice... thats my analysis anyway

No, this is different. Drop in fact seem to be related to wake up from deep sleep, but the point is that this drop is massive and instant i.e. battery instantly drops from 30 to 20, bypassing all other percent states in between. Also, I am sure battery state does not update properly in deep sleep in many cases. At some point I left my phone for almost a day alone (wifi, 3g, Gmail and exchange sync, etc) and it did not lose a single percent, but as soon as started using it I observed instant 20% drop.

And I have even worse problem, can anyone help me?
Take a look at my thread (not highjacking yours, just want some help too), my current widget never reads a real value AFAIK.
It stay with -850 for more than an hour at times...
And my battery life is dismal...
So this means that seeing no battery discharge throughout the night in sleep mode isn't due to excellent power saving feature of the companion core but is in fact poor battery meter?
And yes, my One X shows fast and huge discharge (3-5% at once) when I use after being in long sleep mode

I think it too. Phone on sleep with data and sync on for 1 or 2 hours and % don't change. Use it for 2 min. and it suddently goes down by 5/10%
In my opinion the battery meter lacks of accuracy. This brings to inaccurate real time current calculations and wrong information about what's consuming power when we use it. That's bad!
I'm also seeing these big drops. For me it seems to happen between 100%-60% battery, battery level will drop anything from 5%-10% chunks at a time. After 60%, it does seem to be more stable and drop in 1-2% increments.
I've recalibrated the battery through CWM a couple of times but still get this issue.
It almost seems like there's a bug in the code that is causing the fuel gauge to not update.
I can tell you this, I modified other HTC phones battery driver. The nexus one driver for example updates volt, percent, temp, every 50 seconds while the screen is on. When off the sample poll changes to 10 minutes per update. This is real easy to see in the driver code, and you can filter dmesg log for "batt" and see the time stamps do in fact match this.
But the one x looks to be getting hung up on that part. Anyone know if kernel code has been released yet?
Hey everyone, first post.
I did a search for similar issues and maybe I didn't look deep enough (if so could someone redirect me and mods please delete this post), but I think I'm experiencing some unique issues with my Galaxy S3.
The phone itself is less than 45 days old. It is also my first Android device (switched from iPhone 4) and I am loving everything about it except for this intermittent issue I seem to be having.
My battery life on my S3 has been very intermittent to say the least. Some days I can get into bed at the end of the day and charge it with 20-30% remaining, others I have to charge it mid-late day on my drive home. I have never let the battery completely die on me as I've read lithium ion batteries are best kept moderately charged.
I figured the above is normal, and mostly depends on my usage, however, today I received a notification for low battery (15%) less than half way through my day, and some odd SIX hours after unplugging it.
I've attached some screenshots - let me know if I am missing some and I will try my best to upload them (phone is currently charging off my laptop).
I have no idea what is going on, and as you can see, there's hardly any usage!! I disable WIFI because my LTE is faster and I hate when it searches for my network when I'm on the can (sorry, TMI). BTW my connection is usually full signal with LTE here in the office.
Am I missing something here? Are there some hidden applications running which can be sucking my battery?
Any insight would be much appreciated.
Thanks.
Perhaps there is a hidden culprit draining your battery that does not show up in the stats screenshots you provided. Usually it's called a wakelock or partial wakelock, or sometimes it's a Rogue drain. There are KNOWN culprits. Best if you get the Better Battery Stats and post some screen shots. It has more detailed information.
Also, if nothing is in fact OVER taxing the battery, then it might possibly be a bad battery that does not hold a full charge or even possibly the calibration is somehow messed up. That would be easy for me to compare because I have a spare stock battery.
Apart from the wakelock suggestion, LTE tends to eat battery life - just not to the extent that seems to be going on here.
There was another thread I remember seeing recently about charge occasionally starting to plummet while LTE is active, and I'm seeing similar behaviour in that first screenshot. Let me see if I can find the relevant thread again...
EDIT: This thread is the one I was thinking of.
Hi all,
i recently installed the lineage 17 for my device.
And i have to say i am super happy.
After some investigations i found that AOD is not the best for battery life.
And now i am trying to find another issue. Hopefully i can get some hints here.
so for the timeline in the attached images...
at like 7 am i turned off AOD.
i did those screenshots at like 9 am.
- the device went down to like ~0.5% per hour. (betterbatterystats and battery history)
- and some (10 per hour) wakeups.
at like 12 am i did some more screenshots.
so it looks like 9:30 ish sth. started to use my phone again. not bad but just more.
it seems like this is:
com.android.systemui with ~60 wakeups per hour (1 per minute)
if i look at the battery historian screenshot the current is 16mA vs 60 mA. And you can see that in both cases the screen is off. (created with "bugreportz" on a root terminal and uploaded to https://bathist.ef.lc/ )
I just dont know what is causing this.
(assuming that the battery health did not change in that time)
does anyone have an idea?
maybe this is not phone related, so might be good to put it to a more general forum.
Hi,
i am not sure why but i guess my battery life is now way better.
3 Days without charging. and (as far as i can tell) the same usage as regular.
well only on wifi, not longer than an hour on mobile data.
but i love it
