My HAM2 is reporting battery level incorrectly. It keeps on going normally till about 35% and then within a few minutes, it drops down to zero and turns off. I have used the battery calibration app to try to reset the battery stats but to no avail, the problem persists. Any help will be appreciated. The ham2 is rooted and TWRP installed.

While not to the same degree, I notice once I get to about 10%, it's a crap-shoot as to whether I'm going to get another hour or so or 10 minutes. The longer I have this phone, the more I notice it's a buggy mess.

That is usually a sign of a damaged battery.
Mine is only week old but I've run down under twenty percent and it's drained and dropped consistently. Might contact Huawei since it has two year warranty.
I'll run mine down today and see what I experience.

27% all seems fine. I'll watch netflix for a while and check again.

19% all battery stats report the same. Still watching Netflix. Seems you may have either done something to cause report errors or it is indeed a faulty battery. Good luck

Try recalibrating your battery, if your phone is reporting incorrect charge. The BMS within the battery might need reset.
When your phone is down to "critical level" (before the phone is ready to turn off) reboot into Recovery Mode. Let phone sit and drain until it empties.
Once empty, let sit for 4 hours. This will reset the "low value".
Charge with phone off to 100%, leave phone off. Unplug and let sit off for another 4 hours. Turn phone back on and use as normal, the battery *should* be recalibrated. The reason for waiting is to redefine a "high" and "low" charge state. If current is constantly being supplied or drained, then it will see those values as a "blip" rather than a calibration number.
It isn't always a bad battery, sometimes it's just miscalibrated.

I have this problem too. When my battery gets down to about 15%, I get a warning that I must plug in my charger immediately. I have to do it within 15 seconds or so or my battery plummets all the way to 0% and shuts down the phone. My phone is not rooted, so I don't think I have a "Recovery Mode". Or do I? Would I use the same procedure and be able recalibrate my battery ? When I restart my phone by regular (unrooted) startup after a 100% charge and 4 hour wait, would I get a Recovery Mode option or not? If not would it still recalibrate the battery?

Yea this was similar to my drain months ago . Eh idk why it's changed . Have had the same setup all this time , with amplify (wakelocks/alarm blocker) and deep sleep when screen off (PowerNap) . I have switched the sim to at&t (previously T-Mobile) .. Though both have a similar signal range at home . Not sure , will try with a t mobile sim again and will compare .

My battery on my 10i is acting kind of strange.
It has happened several times now that the phone even when charged from the charger that comes with the phone, not from a pc its not charging properly.
I wake up the phone is on 100% i deside to "snooze" for an hour when i then get up the battery was on 40%, still in the charger Today almost the same only that i woke up to a battery that was on 94% even after 8 hours of charging.
Sometimes the battery life on it is good other days its not. Iv checked if there is any program running that is consuming an awfull lot of power but there aren't.
Is this the battery failing?

What you can do is install xrecovery from Z on it. And then charge is to 100% and run the reset battery fron xrecovery.
Btw, when u charge the phone it is normall that it will drop a little bit when it's at 100%, it will go down to maybe 95% and then up again.
But a drop from 10u0% to 40% is not healty.. you could download the app SystemPanal. it will monitor what your phone is doing and thereby also your battery.

I have xRecovery on it and i did the reset battery, even did a new rom update. and i use the systempanel pro for monitoring to see if there is anything that is consuming to much power but i haven't found anything yet.
its now gone from 94% to 90% (wifi on) since i got up for about 2 hours ago. Not that bad now it seems. But sometimes it just drops and drops.
Maybe i should just get a new battery, they aren't that expencive.

Well 4% with 2 hours is good with wifi on. But yeah it's weird that it drops that hard sometimes. Probably the battery itself then..

The phone was freshly charged overnight. I was using the internet while listening to music through (3rd party) headset and since the 3G signal in the building was kinda ****ty I switched the phone to EDGE (GSM only). Then I quit the Settings menu and opened Firefox, tried to load a web page and at this point the phone froze. I'm not sure if I restarted it or it restarted on itself but after the boot the battery was showing about 40% less. So I turned the phone off, pulled the battery, rebooted, same reading.
I used the phone for a while after that and now it's showing critically low battery and I'm wondering what should I do now?
Is it really so low on battery or the reading is wrong?
Can 40% battery disappear just like that and what could cause it?
Should I charge the battery or let it discharge until it turns off by itself?
Battery screenshot attached.
Perhaps a battery calibration issue caused due to the crash, my advice would be to drain the battery all the way down to zero and let the phone turn off, remove and reinsert battery and proceed to charge till full and then turn the phone on again. Hopefully issue should be a one-off and now resolved.

happend to me before on my htc desire hd..battery pulled and battery stats dropped down the gutter..just let the battery die and charge fully or even just charge it up to 100% from where u at now..doesnt matter it will fix itself...
My phone was doing the same thing, it was rebooting or shutting down two or three times a day, usually a few minutes after taking off of charge.
I have sent it back for a replacement.
Do not drain the battery to zero. There is not reason to go belox 10% charge, as you could damage the battery if going to 0. These are new batteries much smarter then old ones.
You don't need to drain to zero but it won't do any harm if you do. Probably a wee softwre glitch. Wouldn't get too worried about it.
a good option is battery doctor - its a free aplication from the market...
let your battery go down to 20% and then open the app in charging mode...let it charge(dont close the app during the charging process, just keep it open)...woallla.. u have made a full cycle charge - easy as that...

there;s a lot of solutions because poor battery life can be cause by many things, you have to find out what is draining your battery. try calibrating first let it drain until your phone turns off and then if you have cwm install then wipe batterystats and then a full uninterrupted charge
Try setting profiles in SetCPU and freezing apps with TitaniumBackup. Theres a topic for each of these two solutions.

Calibrate your battery.
Then freeze your bloat.
Problem solved.
dont forget you might also being playing with your phone a lot more trying to see all the new stuff in the update. Thus causing more battery drain.

There are some strange things happening with the battery. I let my battery discharge completely to the point where phone shuts down. Then I plugged in to charger, waited for 2-3 minutes so that I can start the phone. Started the phone and saw 50% battery. Don't know what's going on.
I was told by an admin from another site that most of the battery programs do not work with ova ginbread. You go to settings/about/status and observe the battery. I do no I was also getting flaky results with 2 of the battery programs.

That's a GB bug... there's a battery fix in the development section to flash which deals with the reboot battery jumping. (turn off phone at 50%, turn on phone and it says 70%)
I am having problems with my Atrix too. With my usage, I used to be able to get almost 3 days of battery life. Now it hardly lasts a day. I have checked pretty much all settings (sync, sleep) and all seems fine as far as I'm concerned. So I am having hard time trying to find what is causing this. The only suspect I have right now is wifi. I don't think wifi is sleeping even though I've selected "When screen turns off" in the sleep policy.
If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.
Please help.

And when I wake up in the morning, the battery % becomes even less than what it was when i plugged it in.

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.

The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.
EDIT: I had a tip on charging here but removed it after further research read more about batt here..

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.

I had this issue with. 475 too.
Help me please if this is a hardware issue send it back for second time in this week!
Instead of i charged this phone two time totally when i am bought it.first time faulty drainage happened yesterday when i played some game and battery went to 80% then i went to sleep for half an hour and when i turn the phone on again,noticed to battery is lost to 30%!

I noticed a faulty battery usage indicator on mine.
It happened 2 or 3 times, when I plugged the USB cable to the phone (other end connected to a PC or charger) and the phone LED immediately turned green and the battery indicator jumped from 60% to 100%.
Nothing happens if I re-plug the charging cable, the phone keeps saying it's fully charged. Even powering off doesn't help.
The 100% power won't drain faster but I noticed that when it goes to 30% the phone will shutdown because no more juice is inside the battery and the indicator will go back to less than 10% after re-plugging the power cord.

Higher mA output is not necessarily better.
Taking more time to charge is more gentler on your battery.
Pumping up the mAh to 2 or higher will improve the charging time, but the number of total cycle charges (i.e. life span of your battery) will go down and suffer.
Anyway, 3 hrs from empty to full is normal, right? Anything quicker is a quickcharger.

Good thing you included screenshots from GSAM, so that we have something to go on now.
Remaining (Av.use) 18:51
This tells me that you once had a phone that was efficient, so from the day you realised this drop in performance, scrutinize what settings have changed (inc app installation)
Remaining (last 15 min usage) 5:47
IF u continue using your device in the way you have done in the last 15 mins, you have under 6 hours left of battery power.
In the 15% discharge since fully charged (and since when GSAM started taking this data on your screenshot), 62.9% of power was used by screen.
Some conclusions can be drawn here.
As you mention, you were probably playing some games during the 4hrs and 11min the phone was turned on(from when it was fully charged and then unplugged), very likely during the latter stages than earlier from when the phone was fully charged.
I see your screen is set on DIM, and that it has been active for nearly one hour. Your display was on for 25% of the time since full charge, and that has only used up 15% of battery.
Whether it is games or video playback, screen will be on, and looking at the data there is nothing faulty. In another words, set at dim, 7 hours or so of continuous display on sounds about right..(1 hr already used plus 5:47 expected left)
Now, if your complaint is that if you turned your phone screen off and left it that way for a few hours, came back, then found massive power drain, again, a few conclusions can be taken.
It is a shame there is no screenshot of the app usage form the exact same period. But, If you left the game app open in the background, it is possible that power is drawn still, possibly if your phone is not sleeping properly. In another words, CPU usage for game is there even when not used.
Do you have stamina mode on?
Conclusion... Form GSAM data, there is nothing wrong.
Looking at the first screen capture in OP, as you say, drain happened when phone was not awake, and screen off. I can only conclude that there was an app(s) open at the time which had been still running. If the app(s) is not closed or hibernated properly, it can happen.
If your phone felt hot at that time, it confirms CPU usage.In another words something was left open. If it was cold, even though the phone had been off for a while, then it could be faulty battery calibration.
And next time you see this big drop in charge, take screen shots of GSAM from apps and system. We would know then for sure.

And next time you see this big drop in charge, take screen shots of GSAM from apps and system. We would know then for sure.

Special thanks for your great comment
Fortunately,that horrible battery drainage don't happened from yesterday to now.
This means there is no faulty behavior after last full charge that i have been!
I don't know that reason but i done some actions after fully charged phone yestarday:
1.instilling Gsam battery pro as you have seen!
2.Charging with another charger(2mA galaxy s4 charger)
3.setting screen brightness to 30%
4.setting off "optimized backlight"
5.battery calibration with "battery calibration" app
This new informations from my battery behavior after 19 hours fully charged at last day from now and i hope that horrible drainage wouldn't happen in future else!
