I've been noticing sudden abnormal battery drops in my phone after a restart. Any clue what could be causing this? Screenshots attached...

You may need to calibrate the battery as this really should not be happening, it will always drop a bit after rebooting but not too much.

You can safely ignore this incorrect advice.
If you notice a sudden drop like that, just forget about it and carry on enjoying your phone. You'll then notice a gradual increase in reported battery level.
Just switch off your mobile...and take off the battery for 5 min and put it back...and reboot...this is what i have done...when it has sleep issues...and...the problems gone...
Same problem with me

will you ever go and **** off and stop trolling what i am saying is correct, i had the same issue and after calibrating my battery the problem was resolved.

I'd just like to say you're both right. Calibrating your battery will help, but if this does happen again just ignore it. Your battery level will go back up. Just find the nearest iFan and tell them your phone charges itself

I'd love to hear how you calibrated your battery, considering such a thing is not possible on this phone.
Oh, and so you know, if you're going to post incorrect information, of course I'm going to correct you (that's not trolling btw). So what if we've bumped into each other twice in two days, if you're going to post nonsense like this, of course I'm going to respond

No, what you are saying is not correct. If you think you are correct, please show me the interface in the fuel gauge driver that is used to load history data into the fuel gauge chip.
I guarantee you that you will not find any such interface.
Our fuel gauge (MAX17042) does NOT need calibration - see the datasheet for its predecessor, the MAX17040. While the 17042 has some features that, if enabled, could require calibration cycles, these features are NOT enabled in any Gingerbread kernel, and at least one person received correspondence from Samsung that the GS2 does not even have the required hardware support for these extended features.
http://www.maxim-ic.com/datasheet/index.mvp/id/6621
"Unlike traditional fuel gauges, the ModelGauge algorithm eliminates the need for battery relearn cycles and an external current-sense resistor"
There is no need to EVER perform any sort of battery calibration technique on our fuel gauge, other than this simple technique:
WAIT - your state of charge estimate will converge towards truth over time if anything throws it off. Rebooting on low battery is one of the few known cases where the estimate gets thrown off temporarily, and the tradeoff for having this one corner case is that we never need to calibrate our fuel gauge.
Edit: FYI, if you want to be pedantic - I am fully aware that the MAX17042 functionality is built into the MAX8997, just like the MAX17040 functionality of the Galaxy S series was built into the MAX8998. However it's well documented that this built-in function is identical to standalone 17040/17042 ICs.
bad news i'm affraid..
Hello chiefs,
I'm affraid i have some bad news for the OP and others who are facing this issue.
I had it as well (and still do from what the looks of it) and it got so bad eventually that i had to send it to the shop. they replaced the headset (donno what that has to do with anything) and it has worked for a while, until tonight. i have no clue what's going on but if this keeps up i'm gonna see if i can replace this for another phone. it's getting really annoying up in hea'..
Just my two cents..
This is another bothering issue that I find with GS2.
I would rather have a phone that needs callibration instead of a phone that doesn't but that shows "false" information regarding the battery charge.
greatly improved battery life with ICS
I updated to the leaked Samsung ICS LPH ROM and got as much as 21 hours of battery life! So give it a try or wait till Samsung officially releases ICS on 15the March.
I've searched everywhere and it seems there is no real fix for this. WTF.
And the most annoying thing is that when I'm below 15% (which I'm NOT), it won't let me use the stock camera app. Ugh.

So, I noticed that when my battery gets to the yellow color on the indicator, it stays there only for a couple minutes, then it's immediately red. Here's what I mean. Does this look normal???:

Sprint isn't going to be able to tell you anything. Most of the people there barely know anything about the phone itself. Get a task manager that tracks your usage and figures out what exactly is using your battery at what times and you can figure it out for yourself. Try SystemPanel.

Wow ive managed to make it happen everytime. When the battery gets to about 23 % it falls to 14 and really puzzled by this. Is it a major problem or does the battery need calibration
Sent from my PG86100 using XDA App
It's gonna be a calibration/software issue. Either your phone is reading the battery wrong, or the battery is sending the wrong signal.
If it was actually dropping that fast, your battery would explode.
I'm dead serious too.
Try this: When it does the drop thing, reset your phone, and see what % the battery shows when it comes back on. It should jump back up to around your original % (23 you said?). Maybe a middle ground of around 20.
If it doesn't right itself in a week, swap it out.
I waited for mine to discharged till 9% and it didn't happen at all here is a pic I took
I have noticed this as well.

same here the battery turns yellow then almost instant its read !
I had the same issue, kind of ignored it. The drop seemed instant but then my phone would hang out on 14% for a long ass time.
One day I had around 35% and did a data reset (not for the battery issue), just to see if my 3g speeds increase. After the reboot my phone came back up said I had less then 2% battery left, it shut off on me, I turned it back on, and it stated I had 30ish % left. Ever since then my battery hasn't done that drop.
Here's a link to the thread, try it, can't hurt anything I guess. I still don't know if maybe the data reset, reset my battery stats, or maybe the restart did something, who knows. All I know is I had the same issue and don't anymore

Charge it more, your battery is low.
Am I missing something here?
Trolling?
I always charge my battery from dead flat, and this is the first time I have seen this happen, Which is why I was confussed...

You know that isn't good for Li-Ion batteries...

Charging via plug yellow triangle seems to be coming and going.
Is it your first time get a thing like that? If its your first, then I think something wrong with your battery.
Low battery shows red indicator, it shouldnt be green just like the picture.

Hmm. You said you "always charge your battery from dead flat" before. That made it sound like you were doing it on purpose. But I digress.
Also, you should have no problems having the battery go the full day, (I can go the full day no problem - unless I'm constantly using the phone) unless you have something holding a wake lock. Have you installed BetterBatteryStats and monitored your wake locks to see if something is misbehaving?
Yes I have wakelock issues, But last time I tried to give starts thier was an issue with how I submitted it from the phone.
Anyway I sleep very little, and my phone is almost ALWAYS on the lack of a "proper job" means I don't have an 8 hour period of time where my phone isn't getting much use.
Do NOT worry its normal the triangle appeared because your battery has totally finished just Wait for 2 minutes and the triangle will disappear

Well, you should focus on solving those, and your battery life will improve.
Otherwise, my only other advice is to simply have more chargers readily available. I keep one at my office, a car charger each in my car and my girlfriend's car, and a couple at home.

lol.. talk abt redundancy
I suppose I really should get it sorted.
This is an average day for me.
I use buses alot (So no charging port)
I normally have to share a charger with 3/4 devices during the day, so I can't take the it with me.

That does look pretty bad. What is your details under display? (screen on time)
EDIT to add: actually, your screen looks like it might be on for a long time? (solid blue line under battery graph, starting under the "m" in 4h 56m 15s on battery text) If your screen on time is around 3.75 - 4 hours, this is normal.
To get a better gauge, post screenshots after you click both the battery graph above, (which will show signal, wifi, screen on, awake, and charging graphs as well) and the Screen entry. (to show screen on time)
Yea that screen shot is a week old, I will keep and eye on it.

chamonix's reply suggests you try a different modem, essentially. He's saying that in the dump you posted, RILJ held a 3.5 hour wake lock, which is unusually long. Could be that the modem you have flashed right now was struggling to find signal, so it was holding a wake lock.
Have you tried flashing a different modem yet?
Yea i've changed kernel/modems since then, Should I be selecting Other Partial Wakelocks Kernel wakelocks Alarms or Process?

Depends on what you want to look at.
But you're saying the screenshot above is a week old, and the BBS dump you linked to is clearly months old (from Feb 17), so maybe it's worth it to post more recent screen shots and dumps? Otherwise, can you honestly say you've not changed ANYTHING on your phone since either the screenshot or dumps were taken?
No one can tell you anything about how your phone is behaving today using information that is outdated.
The screenshot nothing has changed since then, I have changed things since the dump.
Well I want to kind out why my phone is awake when my it should be sleeping I supppose.
That screenshot their was a day when I woke up and used the device for an hour or so, and then I hadn't used the phone till about 12 hours later.
As you can see the phone kept waking up most of the day.
The info on Android OS for that screen shot was CPU Total 1h 6m, Kept Awake 4H 9m
Now, before you say anything, I know that issues similar to this one have been reported previously (I found 3 other threads, but there might be more). However, during troubleshooting of my friend's SIII, I found the following screenshot in battery usage (which was slightly disconcerting, to say the least). Nothing I've ever seen, on any of the phones I've ever worked in, was even remotely similar to this. No extraneous or abnormal usage was reported to me, and, possibly even more disconcerting, random shutdowns have been occurring every 15 minutes or so (which I would guess are from the overheating, but the phone didn't really seem that hot to me). I am left to guess this is either a battery issue or an active process forcing the processor too much, but I was left out of ideas, and am cautiously recommending a root and underclock if this persists. However, if you have any ideas of what might fix this (other than the rather drastic root + underclock), I'm all ears.
Thanks!

An app drain your battery.
Look at the picture.
No screen on but a lot awake.
If I was you, I root my phone, install titanium backup, backup my app and make a full wipes.
Or if you don't want to root, do a factory reset.
If it don't happen after this, it's due to an app

That was actually my first idea. It's not actually my phone, it's a friend's who asked me to do an impromptu IT session (I use an HTC Wildfire, barely running 4.0, which may be antiquated, but I'd hate to get rid of). I originally thought it was an app, but checking the actual battery usage list (which I'll try to post here as soon as I can get a hold of the phone again) I didn't see any standouts. Running processes turned up all the usual stuff, which is what puzzled me most.
I'll try to convince him to wipe, root, and underclock, but it's a lengthy process, and (understandably), probably a bit too much for someone who just started using Android, which inevitably means I'll need to do it.
Battery Usage List
Got a hold of the phone via email, this is the battery usage list. As I said, nothing really out of the ordinary.
Would a factory reset not be the first step?

Since it is your friend's phone and he is not ready for rooting stuff, then I suggest factory reset and if problems persist, send it back to Samsung for repair.

The sudden battery drops on the usage graphs here look like a nasty device hang with high current consumption, possibly a near-short-circuit one, followed by a reboot. NOT like an app draining the battery. Also, no phone should ever overheat to the point it hangs/reboots under room temperatures, no mattet how badly a wrongbehaving app taxes the CPU/battery.
Sure, factory reset is worth a try, but do start seriously considering an RMA
Now I feel like a noob for not knowing what "RMA" means. But yeah, the drastic drop in the battery chart and the random shutdowns probably indicate something more serious than a misbehaving app. Let's hope not!
RMA - return merchandise authentication or something like that, i dont remeber the exact abbreviation. It means - use your warranty and return the device for repair/exchange.
Im also using the international model and Im having the same problem except I never have the issue of overheating or freezes. Its just that with minimal use the battery drains a lot faster than expected and wont even last 10hrs until i need to charge it again, I have wifi and all motion controls set to off and even rooted my device to use the Voodoo RRC Tool as recommended by a dev. Still its been a pain.

Now this does looks like a software issue.
I have similar issues. I got the phone over one week ago and it was great with battery life with some random freeze and blank screen when using Navigation with data connection turned off. However, the phone started to drain battery like crazy one week later: Completely drained within 8 hours, with only WIFI turned on but not connected and SIM card removed. This is after I factory reset the phone without installing any apps other then the stock apps. I also notice that it would not connect to any known WIFI APs that have signal strength below 75% (approx), warm to touch (probably caused by battery drain). It also won't charge from my laptop USB2.0 & USB3.0 ports or any other chargers except original Samsung charger that comes with the phone.
Has anyone else experience similar issues like mine? I don't think it's software related.
I'm currently using CM 10.1.3 STABLE with the radio included in the latest JB update for the UK. However, with this, battery usage when using mobile data is terribly high (I've tried two different batteries) and is eating about 1% per minute, even I know that's ridiculous.
Are there any suggestions?
Thanks.
Yeah, you need to use the one which gives you the best signal. That'll then be the one with the lowest battery drain as your phone isn't searching for a signal constantly.
To do that, test the modems released by your carrier for your region /country. If you still don't find one that works for you, flash whichever one takes your fancy. Don't flash modem +RIL as you're on custom rom, you want modem only.
The other thing is, have you installed betterbatterystats? My guess is that it's something eating your battery, not the phone searching for signal. Find the xda thread for it and follow the instructions in the OP to figure out what's causing the drain.

It's no use to rely on BBS whilst you're using the phone. You need to look at the stats after you have left it idle for 4 hours or so. It's also not very useful to post the stats only, post the dumpfile after it's been idle for 4 hours. If you post the dump in the BBS thread the guys there are kind enough to analyze the dump.

I'd prefer not to analyse dumps from a PM sorry. Nothing personal, but your best bet is to post your dump in the BBS thread itself. The guys there will analyse your dump and give advice how to proceed from there.

Did you try and delete the batterystats.bin in /data/system. ?
And try recalibrating your battery:
-Recharge your phone,
-Use the phone as you normally do and let it Discharge,
-When it Discharges and Turns off, Recharge it again,
-Do that for 2 days.
Maybe it will work, im not sure try it. But as i see i think that the batteries are weak or something. You know the batteries have some sort of a self remembering method that remembers the usage and Discharging of a battery.

Spotting a weak battery
I found it here.
Cell phone shuts off
If the battery’s capacity has shrunk, it will still read "full" even if there is very little power in it, and the phone will quickly run out of energy and turn off. Or, the phone could be at fault. Borrow a battery from another phone of the same type; if the phone works with the other battery, it’s time for a new battery.
Charge does not last
A cell phone battery should be good for around 24 hours between charges. Dramatically decreasing battery life is a sign of a dying battery.
Swollen battery
Sometimes swelling is visible even with the battery in place. To test for swelling, remove the battery and place it phone side down on a level surface. If it can wobble or spin, it must be replaced or it could begin to leak and damage the phone.
Hard spot
Squeeze a battery along its phone-side edge; if it has a hard spot, replace it.
Visible corrosion
Check the contacts for corrosion or other damage. If this could be a result of water damage, the battery should be replaced as further damage may be hidden inside the battery.
Water damage indicated
Cell phone batteries often have an indicator strip that changes color if water damage has occurred. Some cell phones also have such a strip inside the battery area; know what color the strip should be and what changes indicate damage. Damaged batteries should be replaced.
Excessive heat
If a lithium ion battery gets unusually hot during use or charging, it is getting worn out and should be replaced. Nickel-based batteries normally get hot during charging, so this is not a trouble sign for them.
Hope i helped you.
Hi Guys!
Following Question. I got myself a new Galaxy Tab S3 and realized somehow, that i got a massiv Battery Drain. For examlple today after i finished charging i didnt used it for couple of hours and leaved it idle and locked. After 2 or maybe 3 hours i saw that the battery lost abt 6 or 7 percent. Does anyone saw some similar problem? I already tried wiping the cache.
What should i do in that case?

Does the Wifi usually drains that much??
For some reason it does on this tablet. Tried freezing apps, greenify, and naptime with same issue

I'm having serious issues with battery life, tried with all those apps, rooted. The battery life on this thing is a disaster

Battery life is great as far as SOT, stupid tablet just doesn't enter sleep unless you turn off wifi. Hopefully a future update will come out that fixes this or we'll see some custom roms that have this issue resolved.

But in actual use, I could be annotating a PDF file with the pen and it seems to drop really fast while the screen is on!

Odd. I use my tablet for media consumption and I have to charge my tablet every week & a half. I usually have it streaming videos around 75 minutes 5 to 6 days a week, so the really quick rough math is around 8 or so hours of SOT.

For me too when i use my tablet for writing, but i guess it's the digitizer
I experience large battery drain by wifi in sleep as well. After two/three days of idle tablet won't even power up until I plug it into the charger. Turning wifi off before putting tablet to sleep helps, but's really annoying. One would expect Samsung would fix this ASAP.
I take my earlier comment back, aqdc still has the wifi drain bug, very annoying. Also, the new ipad pro makes this look like a joke. We need an 8895 in this tab not useless qualcomm chips.
Latest AQF3 still has the bug, I guess it's time to give up on this tablet and just use my S8+ for everything. Samsung support thread in case in anyone wants to vent:

Tried to find the root cause using wakelock detector and greenify, didn't yield much. The problem is likely at the system firmware/wifi driver level. I suggest all folks start returning their S3s , teach Samsung a lesson.
AQF5 build came out today for Korea, trying that now. The way they are increasing the build numbers, hopefully they are actually fixing something. Interestingly this had a modem file too though the SM-T820 is wifi only.

No dice still with AQF5 KOO firmware today, I officially give up. Likely a hw issue , only reason they have not addressed it across 6 firmware updates. Too bad since the tablet is very decent otherwise. Unlikely this will ever get fixed at this point since this is not a Note 7 type headline grabber. Time to find an used S2 to replace the one I sold or wait on something else.My S3 is going back tomorrow.
SOLUTION for SAMSUNG S3 TAB
go to SETTINGS - CONNECTIONS - in the right top corner click on ADVANCED. click on to "KEEP WIFI ON DURING SLEEP" and select NEVER.
I was pulling my hair out as my tablet was running out of battery unless I manually switched off wifi. Hope this helps.

Oled display`s use a huge amount of power when showing white/light screens, oled is best for video(supposedly use less power than lcd)
Buy an lcd display tablet if you do a lot of writing/drawing.
