My original device always seems to take forever to go below 100%, and I just got a new device that has the opposite issue - it never goes above 94%. So I did some further tests, tonight.
My 94% device goes down fairly steadily once unplugged. But, the device at 100% does not. Also, when the 100% device is drained and I recharge it, it still says it's charging when its at 100% - so what does this mean?
I think that the battery calibration is off, as we already assumed. So, my 94% device is really 100% and I suspect that it would survive beyond 0% as it probably still has 6% juice left in reality. And, in the case of the 100% device, it's probably mis-calibrated to 105 or 110% (or more?). Since the UI can't show you 105%, it just shows the max of 100% until it goes below 100% which can take some time. I also suspect that the device would cut out at 5% or 10% since it's actually drained completely.
So that's the reason, I think. As to the fix, I don't know. What's weird is that these two devices are so different in terms of how the battery status is calibrated.
How can this be fixed? Or "Recalibrated?
I'm letting one of them completely drain, to see what happens.
At least the 94% one gives me an idea on what the battery life is, since I can just tack on +6%. But the one stuck at 100% is a complete mystery - it could be 5% off, 10% or even more.
Also, these run on 2 cell batteries making 7.4V nominal. All the devices before are using single cell batteries at 3.7V nominal. So Android may have issues with that voltage difference.

I had the 100% battery issue before and it took a long time for it to dip below 100% (so long that it seemed unreal). Later I decided to let it drain to zero before recharging it to full again. Since then the battery indicator seemed to behave normally and discharged at a normal rate when the tablet was in use.
Have you tried deleting /data/system/batterystats.bin to wipe battery status? Mine sits on 100% for ages so I'm trying this now.

I tried that once, by setting it to never shutoff and letting it go over night. The next morning I charged it to green plus 30m as someone suggested in the TnTL thread, but I still had the problem of the meter sticking at 100% for a long time.
Anyways, I installed 3.0.0(TnTL) on monday and decided to also use the CWM clear battery data option, and now it seems to be dropping more as expected, but I'm not entirely sure that I did it completely correctly as by the time that I did the clear battery data option it would've been below 100% charge since I did so AFTER running the update.zip... just have to wait and see now...
Battery Stays at 100% For Ages
My battery stayed at 100% for ages the first time I charged it. Then it dropped quickly and cut out around 50%. I recharged it and it seems to be behaving more normally now. It still seemed to hang at 100% for a while, but no where near as long as the first time. I'm waiting to see at what percentage it dies this time.
my zt 180 tablet never got above 94% also. And it dropped pretty quickly and at around 40% it seemed to get a second life and slow down, but eventually it went all the way down to about 10% and then I would charge it (about 3 hours max). It too is a 7.4v supply.
My Odroid T had a 3.4 supply and it was pretty linear, showed charged at 100% and went down accordingly, though the developers had some issues with a few software releases where it did behave erraticaly and they did a few patches that fixed it.

I also had the issue of battery showing 100% for a long time and then cutting out around at 50%. One of the posts mentioned doing a battery stat wipe in CWM after charging to 100% + 30 minutes.
I did this with a little twist of my own.
I allowed the battery to drain completely and tab to shut off. Plugged in the charger and immediately did a battery wipe in CWM. Allowed the battery to charge fully upto 100% + let it be on charger for additional time till the battery symbol in the notification bar no more showed charging sign. Again did the battery stat wipe in CWM and then rebooted the tab.
Since then i observe that the battery has been draining as it should be expected to. down to 72% after about 4+ hours of use. I will still be monitoring the battery discharge further for two or three more charge cycles. But I feel doing battery stat wipe in cwm 2 times at full drain and then again at full charge might have helped caliberate it properly.
Let me know if anyone else tries this and gets same or different observations.
Try installing this to measure your current usage over the life of the battery... (dont have a GTab and still considering). Since most likely this widget and the battery monitor are using the same API we will see if its a hardware sensor issue or a software issue...
http://www.appbrain.com/app/currentwidget/com.manor.currentwidget
I suspect its in their battery monitor and not the sensor or API... if that is the case it should be easy to debug (if you have the source). Typically these issues are due to poor polling algorithms...
Im new to android so I am unfamiliar with profiling capabilities of the platform...(Still learning)
Perhaps this will be one of the 'little fixes' that will be present in the latest FW update when VS drops it tomorrow. I have the 100% unit BTW. A fix would be nice.
Reading this thread this morning it got me thinking about my gtab battery situation. When I first got the gtab, the battery stayed at 100% for hours, then the percentage dropped like a rock. Over time, the battery dropped in more regularly, although it drops in large numbers (like from 100% to 83%, then to 67%, and so on). I'm currently running TnT Lite 3.0.
This morning I charged the battery to 100%, and while plugged in (to the AC outlet), I reset the battery stats using cwm. The battery today has been steadily going down throughout the day as I would expect. In over 8 hours, I watched the battery go down steadily from 100% to 84%. So far, so good.
my exp
Tried draining once, just let it sit, didn't fix it.
Tried again but this time I kept the screen on and watched the voltage, shutdown was near 6.8 volts. Now the meter is accurate. YMMV...
@it'sDon - it wasn't fixed in the update.
I was in the same boat as most of you. Took a very long time to go down from 100% and then zonked out completely at ~10-15%. It's now been charging for a few hours and it's been sitting at 100% for quite a while but the light is still red (so it's still charging) which means it will probably happen again looks like it's charging to some value over 100% and when it discharges, knocks out while the meter is still reading as having juice. Roebeet is 100% on the money.
I am going to try the CWM battery value reset some of you mentioned to see if it does something once my light is green, then I won't charge it and watch it like a hawk once it hits 20% to see if it shuts down at 10-15% or a value less than 3% which is acceptable I think.
I never had a problem on my stock(ish) g-tablet. That is until I installed the latest update.
I had to do a data wipe before any of the cosmetic TnT changes would show. After that the battery now seems stuck at 100%. This wasn't that way before, so I will try draining the battery, and see what happens.
Since I found that this was tied to my latest update, I think that I should call CS and complain.
My battery drain didn't make a difference, either. Still haven't pinned down a fix that works.
At least those of you with 94% max have a general idea when your battery will die. With us "100% forever" ones, we have no clue.
Actually, I may not have a problem after all. I have had my tablet on for about two hours. It is now showing the battery at 86%.
Hi guys,
I've noticed that if I plug my phone to the wall charger, when it reaches 95% it just stops charging. I can unplug it and plug it again, and I can reach 100% by repeating the process multiple times, but not in one sitting?
Is this normal? Does it happen to you? Does it get better?
Same here

as far as i know, its an known bug
Its by design - charging the battery to only 95% level & then the following discharge. It elongates the battery life. It should never charge to level's exceeding the above.
It's not a bug.
Most batteries lifespan drop if being on high voltage too long (100%)
So usually manufacturers will try to let it state it is fully charged before it even reach 100% to extend the lifespan of the battery.
But if you really want to see it charged fully you can do a battery stats wipe in recovery after a ROM flash. It will be able to charge to 100% fully.
Hope that helps.

tried this methode, but no success.
i come from a X10 and SE build in a charging algorithm: battery charged fully, hold this value for one hour and let the battery fall till it reaches 90% and charge again.
do you mean such methode to extend battery life??
the phone from my boss (i9020) charges to 100%, my (i9023) only to 96%
96% is ok, as i said, being in high voltage often kills the battery. 96% keeps it's lifespan much longer.
Being said that, even extremely low voltage kills the battery too. So usually your phone will die before the battery reach 0%
Not this again
From the FAQ post, in this very forum, which should be read before posting a new thread:
Q: I unplugged my phone, and my battery dropped from 100% to 95% immediately, or it won't/takes along time to charge past 99%, what gives?
The answer leads to this informative article about what your battery gauge is telling you, and why 100% is probably not what you want ...

While I thank you for your reply and linking to that article, that is a related issue but not exactly the same. The usual behaviour is for the battery to indicate a 100% charge and then drop to a lower level, as you bolded in your post. The behaviour I'm talking about is it never going over 95%.
Not a big difference, but enough to notice the change and ask about it. Don't you think?
I myself own a GT-I9020T & have never seen the charge levels exceed beyond 95%.
You are right, your description is subtly different than the post in the FAQ. I have to admit laziness in assuming that they would be one and the same 'problem' ... apologies if they're not.
Well, you did give useful info even though you thought it was an old, tired question. I can't see a reason to give apologies there
Turn the tethering on while charging; it'll charge the battery up to 100%
I think my Vibrant had the same issue / feature. It's probably a Samsung feature and not a bug.
Sent from my Nexus S using XDA Premium App
Mine hits 100pct sometimes but will always stop charging until it drops below 90. A good feature to save the battery. Makes 0 sense for it to be charging every time it drops 1pct for hours at night while on the charger.
I'm wondering if people seeing a difference in the overall charge cap is a matter of rom? I've been using cm for practically ever but I know some people are on stock. I'm sure it's possible something is modded in there to make sure it hits 100 before it stops.
Just a thought.
On nexus s with stock rom I was able to charge to 100%

Hey guys,
I've read what feels like a few hundred posts on conditioning your battery for optimal charge/longevity, but few seem to add up to each other. Some have said use till at 10% then charge, some have said fully discharge then charge to full while powered OFF, and still others say differently.
I'm in the process of letting my Sensation drain fully (edit: it just died!) and figured I'd gather a quick consensus... what's YOUR preferred method of battery conditioning?
I posted this in another forum and the response I got was somewhat weak. Instead of re typing everything I will cut and paste my posts and hopefully you guys can guide me in the right direction!
Here was post 1 -->
I just bought a Rooted Nexus S from ebay. It is running this ROM Nexus S ICS 4.0.4 stock OTA ROM (IMM76D)
Now, I know nothing about android, I'm coming off a series of old turd phones because i'm always breaking them. I'll probably break this one too, but hopefully not for a while.
When I got the phone I put the battery in and turned it on, then charged it overnight. It will only charge to 54% and stay there. I talked to the seller he said it charged normally for him. He said he did a complete wipe and USB wipe before he shipped it.
The battery seems to drain normally (I guess, I have nothing to really compare it to) from 54% but it would be nice to have it charge to the 90% -ish range haha. I allowed the battery to drain to 40% and put it back on charge, it been on charge for almost an hour and will only charge to 41%? Do you guys have any ideas what I can do to fix this? Is this a sign it needs a new battery, or a software glitch? The seller said the battery shouldn't need replacing.
Also in the battery app under setting, Android System is using 28% is that a lot?
My last question is an important one to me haha. Is there anyway to convert the querty keyboard to a T9? I 've gotten used to texting with one hand and T9 makes it so much easier to do so.
Thanks everybody!
Someone recommended I try the battery calibration app So I did!
Post 2
Ok, I ran the Battery Calibration app. I let my phone charge for hours. It would only charge up to 38% this time. However, the percentage was 38% but it was charged to 3810 mV (and would not charge past this point). And full charge is approximately 4200 mV according to the Battery Calibration app. So I assumed that 3810 mV was my current battery's max charge (keep in mind it is a couple months old) and set battery calibration at that point.
This is from the app description --> It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
So thats what I'll do. I should mention that even though I ran the battery calibration, the battery percentage has been draining from 38%. In other words, my phone now reads 26% battery charge, but is at 3758 mV.
I'm thinking that when I go to charge it after fully draining the battery, it will hopefully charge close to 100%. It seems as though the percentage is the only thing that is off. Because the mV reading seems accurate.
Here is a screenshot, what do you guys think?
This site won't let me post the screen shot until 8 posts, but I will do that once I get there!
Post # 3
The app says to let the phone fully discharge after calibration. I am now at 15%, but mV is at 3658. Should I recharge when the percentage has dropped lower, or when the mV reaches a low point? Are these phones really this finicky. I'm starting to miss my old 2007 flip phone haha
It's now at 14% and now asking for me to plug it in to charge lol but mV is still way high (3655)
Post #4
update, charge % reached 0 and the phone shut down. Now charging, Current charge is at 0%, 3595 mV. No one has any idea whats up?
Shouldn't mV be near 0 when charge is at 0%, and be near 4000mV when charge is near 100%?
hopefully you guys can help me fix this issue. Otherwise it'll have to go back to 'ol reliable, the 2007, multiple cracked screen, nokia slider lol It's not pretty, but it works!
There is a built in safety feature in our batteries to prevent deep discharges. IIRC, the safe cutoff point is around maybe 34xx mV. I could be off, but its to prevent damage to the battery. Here's more on them
http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery
As for voltages, a full battery should be around 4100mV. Mine tops out around 4196. I'm not too familiar with all of it though. Most of the stuff I learn is through observation and links others provide.
Thanks for the reply! So are you saying that when the voltage is around 34xx the battery charge % should be close to or around 0%. And when the voltage is near the 4000mV range the charge %tage should be approximately 9x%
Do I have the right idea here?
Its hard to say while its charging. My phone is at 4000mv around 70% so I don't really know exactly how it works. But a full battery should read around the voltages I posted. There's people on here who know more about it, so hopefully they'll chime in.
But yes. When its close to zero, it should be around that range. It will differ from battery to battery.
Ah k thanks! My original problem was that the phone would only charge to 54% and would not go past that point. I'm waiting to see if it will get into the 90 ish % range after running the battery calibration now.
The app itself doesn't actually do anything. The stats will get reset once the charge reaches 90% My girlfriend's phone was the same way. It wouldn't charge past 75%. I let the phone run dead and charged it while it was off and it fixed the problem. If it doesn't go to 90%, try charging while off and just letting it run until it gives the warning to charge, turn it off and let it charge overnight .
Ok. Well I let the phone run dead earlier today as I mentioned in one of the above posts. But I didn't charge it with the phone off. I put it on charge with the phone on, and now it won't charge past 11%
It just seems to be getting worse and worse? It's been going between 10% and 11% and has been at 11% for about 2 hours now. Maybe this time I will drain it again and try charging it with the phone off like you suggested.
This is slightly annoying
All else fails grab another battery. They're dirt cheap on eBay. Just get one from a reputable seller
Ok, so I let the battery drain. then fully charged it with the phone off. When I turned it on, it had 47% charge.
The guy I bought it from said that before I buy a battery I should download an app called rom manager and download a new rom. he thinks its a software bug because he had no problems with the battery when he was running cyanogen mod 9 on it.
I wouldn't mind giving trying this, except I don't even know what a rom is. Is it operating system? I like the way the phone works now, If only I could get it to charge fully.
Thoughts?
Ok, I just did a bunch of reading and downloaded ROM manager premium. Hopefully I get this figured out. Owning one of these phones is a lot of work
lts pretty much a pocket computer. Coming from an older type of phone, a lot of things are going to be different. Gotta start somewhere. Reading up on it and toying around with the phone will help in the long run. Trust me.

Haha, pretty much. I'm slowly starting to learn more. I didn't think there was this much of a learning curve, thats what took me by surprise thats all. I'm a fast learner so I'm not too worried. I didn't have time to play around on it tonight, maybe on the weekend. I found out I could use it without the sim card which is awesome! Because now I can use old faithful while I learn more about android.
Thanks for the help so far though, I'm sure I'll have more questions soon haha
Haha. Yep. You can have tons of fun just using it over wifi!
Do keep in mind, fully dishcharging a lithium ion (li-ion) battery deteriorates the battery even more. We only discharge because older phones use nickel cadmium batteries which need more maintenance to get to their maximum life span and use.
Off topic though.
Battery calibration just wipes your battery stats. You can do this by going into any recovery program eg clockworkmod receovery or team win recovery project. You can wipe the battery stats yourself. If that still doesnt work. Try doing a clean install of your custom rom or kernel. If your not on a custom rom or kernel. Nor your rooted. Try formating the SD card in the Nexus S (or fully wiping the sd card). Than do a factory reset.
Ok, so I finally had some time to learn to flash etc. After backing up, I downloaded and flashed the same rom from SD, I cleared davlik cache and also selected the wipe data and cache option from ROM Manager (I assume that this is what is called a clean install?)
This is the ROM I am using http://forum.xda-developers.com/showthread.php?t=1653713 Slightly customized stock ROM, rooted.
After start up I waited a while and then plugged it into the charger, it only charges to 54% still. Sometimes it creeps up. One thing I noticed is that if I use the phone while it is charging, it actually drains the battery. So it will go from 54% to 52% and slowly drain. Is this an indication of a pooched battery?
Any suggestions? I will order a battery. Where do you guys order your batterries, I read that the oem samsung 1500 is reliable.
This is intended to be generic - Moto G3 with any ROM - stock or custom, and any apps on it.
I had drained my battery to 40% chasing a supposed weak signal problem, and noticed that it seemed to take many hours to recharge. Probably didn't help that I left it on while charging. I have always recharged this only letting it get down to maybe 80%. Some folks say that is bad.
I ordered a replacement battery on ebay. Currently undecided whether to install it.
Searched around for determining battery health and yes there is the usual very extensive test that will probably kill your battery by the time you are done.
One app said my battery was "good". Another wanted to calibrate it "Advanced battery calibrator" which wanted to install "battery life repair" which wanted to check my battery, supposedly found some bad cells, and when told to fix them, supposedly fixed them (NASA should be alerted about this for things like Mars Rovers!!!)( ), and of course a bunch of reviewers saying it's fake, and etc.
BUT... All that aside, I thought I would post that to see if anyone has found any great pearl of wisdom as to determining when to replace a battery. Or how to extend it's life. Or anything else pertaining to MG3 phone batteries..
EDIT: found this at http://www.popularmechanics.com/technology/gadgets/a15731/best-way-to-keep-li-ion-batteries-charged/
One cycle is just one bout of discharging, but how much energy you discharge in one go—a measure referred to as depth of discharge (DoD)—matters bigtime. Lithium-ions really hate a deep depth of discharge. According to Battery University, a staggeringly exhaustive resource on the topic, a li-ion that goes through 100 percent DoD (the user runs it down all the way to zero before recharging) can degrade to 70 percent of its original capacity in 300-500 cycles. With a DoD of 25 percent, where the user plugs it in as soon as it gets to 75 percent remain, that same battery could be charged up to 2,500 times before it starts to seriously degrade.

Oddly that's what I've been doing. Maybe battery's fine...? Figure 2 years at 1/day = 720. But what would leaving it plugged in all night be considered?
Then there's this which says don't leave it plugged in when it's fully charged (which I do overnight)
https://www.sciencealert.com/here-is-the-best-way-to-charge-your-phone
Yes, we know. Our smartphone batteries are bad because they barely last a day.
But it's partially our fault because we've been charging them wrong this whole time.
Many of us have an ingrained notion that charging our smartphones in small bursts will cause long-term damage to their batteries and that it's better to charge them when they're close to dead.
But we couldn't be more wrong.
In fact, a site from battery company Cadex called Battery University details how the lithium-ion batteries in our smartphones are sensitive to their own versions of 'stress'. And, like for humans, extended stress could be damaging your smartphone battery's long-term lifespan.
If you want to keep your smartphone battery in top condition and go about your day without worrying about battery life, you need to change a few things.
Don't keep it plugged in when it's fully charged
According to Battery University, leaving your phone plugged in when it's fully charged, like you might overnight, is bad for the battery in the long run.
Once your smartphone has reached 100 percent charge, it gets 'trickle charges' to keep it at 100 percent while plugged in. It keeps the battery in a high-stress, high-tension state, which wears down the chemistry within.
Battery University goes into a bunch of scientific detail explaining why, but it also sums it up nicely: "When fully charged, remove the battery" from its charging device. "This is like relaxing the muscles after strenuous exercise." You too would be pretty miserable if you worked out nonstop for hours and hours.
In fact, try not to charge it to 100 percent
At least when you don't have to.
According to Battery University, "Li-ion does not need to be fully charged, nor is it desirable to do so. In fact, it is better not to fully charge, because a high voltage stresses the battery" and wears it away in the long run.
That might seem counterintuitive if you're trying to keep your smartphone charged all day, but just plug it in whenever you can during the day, and you'll be fine.
Plug in your phone whenever you can
It turns out that the batteries in our smartphones are much happier if you charge them occasionally throughout the day instead of plugging them in for a big charging session when they're empty.
Charging your phone when it loses 10 percent of its charge would be the best-case scenario, according to Battery University. Obviously, that's not practical for most people, so just plug in your smartphone whenever you can. It's fine to plug and unplug it multiple times a day.
Not only does this keep your smartphone's battery performing optimally for longer, but it also keeps it topped up throughout the day.
Plus, periodic top-ups also let you use features you might not normally use because they hog your battery life, like location-based features that use your smartphone's GPS antenna.
