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%.
This is not a guarantee of battery life extension or performance. These are merely steps (in most cases) to possibly help prolong and restore battery longevity.
First lets understand something about battery charging. The most common mistake is to overcharge a battery. While one is inclined to charge when they see the low battery message, overcharging is detrimental to the battery. This is not good for the life expectancy of your cell phone battery, especially if you are expecting longer life from your battery. Over charging heats the battery, and drains its life expectancy.
Second, it would appear that after flashing (ROM’s, Kernel’s etc.) multiple times, your battery might not hold a charge all that well. Trying these steps may help improve battery life.
> Turn the phone on. Plug in the charger (not the USB to computer) and charge completely> Disconnect the charger and turn off the phone> Once completely shut down, plug the charger back into the phone. Let the phone completely charge, while phone is off. In some cases the phone may give a tone when charged. You can check its status by touching the volume up or down> Once again unplug the phone from the charger> These next steps are curcial. 1.Turn the phone on (give it time to boot completely) 2. Power it off again. 3. Connect to the charger once again. 4. Let charge to full one more time. Unplug the phone!
In most cases, this procedure need only be done once. Remember turn off bluetooth, intranet and other applications when not in use. These accessories pu a tremendous drain on a cell phones battery life. This is why they should be turned off, when not in use.

i feel like i do this every time i recharge my battery because every time i charge to 100% then turn it off and plug it in, it takes another 5 min to charge to 100 while its off. Literally, every time i bump charge it.

Mhmm, an explanation of the bump charge. Been written here before, but eh. Maybe someone lost theirs. I lost my txt file with the instructions a while back lol.
The way I see it these instructions only help to provide a more accurate battery count. Whether the battery is displaying correctly or not, juice in the battery is juice in the battery. Nothing more nothing less. This whole battery issue is ridiculous.
I think it'd be a good idea to remove the battery icon from the notification bar all together.

No. Your phone has software in it to detect how much battery life is left for a variety of reasons; it turns more battery-intense functionality off at 5%, the camera for instance, and keeps enough battery power so that it can run its shutdown procedure, instead of just dying and losing whatever's in memory at the time.
You also don't want your phone thinking that 19% battery is 1% and turning off or telling you to charge it, as charging a battery that isn't fully discharged is a great way to lose long-term battery life. Additionally, how much would it suck if your phone software thought that 75% was 100% and stopped charging? You could then be leaving for the day with 3/4 of your battery, thinking it was full.
There are plenty of reasons to want this to be as accurate as possible. Unless you just don't give a crap if your phone is usable or not

I was having all kinds of issues with my battery draining too fast. I unplugged at 7:30AM and by 10:30AM it would be at 60%. I tried the bump charge and all that, but then I realized "It's the apps, stupid!" I started running a task killer after I unplugged it, and now I'm making it to noontime and I'm only down to 80%.

If you are running a custom rom it is also good to delete the battery charge stats when booting back up after step 4. If you have CWM just boot into recovery, go to advanced, then clear battery stats.
There is a way to clear it if you don't have CWM, but I don't remember what it is and I think most people have CWM anyways.
I check my apps frequently. One day my weather widget was going nuts and was using GPS non stop. I pulled my phone out at lunch and the battery was in the yellow. Granted I haven't seen that happen again it has made me reconsider even using apps/ widgets with GPS
widgets kill battery. I had several pages of widgets and I had to wipe by phone, remarkable how much "better" the battery was after that. Weather widgets look great but it costs to run them.

I've a feeling it has less to do with the actual widget and more to do with their constant updating when there is a poor or nonexistant connection.

I would love some advice as a noob here. I've only had my Cappy for a little over 2 weeks. I've done the battery calibrate trick, but still don't see very good battery life. I unplugged from the charger at 100% at 10pm last night and left the phone on all night. Wifi and GPS were turned off. Beautiful Widgets is set to update weather every hour. The phone received 7 sms messages during the night. When the alarm went off at 6:30am I was at 70%. It's 10am now, so it's been off the charger for 12 hours. Here is what I show:
Voice Calls 34%
Cell Standby 23%
Phone Idle 16%
Display 15%
Android System 4%
Beautiful Widgets 3%
Android OS 3%
Android Core Apps 2%
antivirus 2%

Would anyone suggest Advanced Task Killer or Juice Defender?
There are some good tips for prolonging and caring for your Battery here: (Can't post links, google search: site:arstechnica.com battery life ask ars)
However, cell phone batteries rarely run over $30 (I have seen capivate batteries as low as $13), if you just always fully charge it you will still see a good 8-12 months out of it, and then just buy a new one. $30 a year is worth it to me to just let the thing fully charge so that I can use it for longer.

If you fully charge and run the battery, done several times, the battery will eventually run better. Surprisingly, there is a "break in" period for the battery.
I appreciate the advice on the task killers and such. I don't use one, and after reading that stuff, I won't. I pulled my phone off the charger yesterday at about 1pm. By the time I played some games, did some web browsing, made some calls and did some texting, it was still at 70% when I went to bed at around 10pm. This morning at 7am, I was shocked to find that it was still at 67%! I don't have a clue what was different. It typically hogs up 25-30% overnight, but this time it only did 3%. I wish I knew what was different. This is so weird!
This happened twice today..
For e.g: If my battery is showing 15% and then i restart my phone it suddenly shows 50% remaining..
Am using Battery Indicator to show me in % how much is remaining (though even the htc battery shows the difference in this case)
Any idea why is this happening and how to solve this??
Oh and how to stop the: Show Me app?? Keeps restarting and sucking my battery..
Could someone please help me out here with this weird problem??
It keeps happening everytime i restart my Sensation..

Its a 1 day old Sensation.. Havent rooted it yet..
I saw the same with my mine. I allowed the battery to drain until the phone shut off and recharged over night to 100%. I did that for a few cycles and mine seems fine now.
The battery % indicators only show what the phone software *thinks* it currently is.
The Sensation battery ranges from approx 4200mV (full) to 3000mV (empty).
The problem is sometimes the phone thinks those numbers are different. E.g. when you turn on your phone for the very first time, or flash a new ROM, if your battery was half full at 3700mV the phone would then think that was the 100% level (why they say charge a battery fully for a long time before turning your phone on for the first time).
This leads to various funnies such as a battery seemingly staying full for ages (the phone thinks 100% is much less than 4200mV so until you drop to the phones level your battery %age doesn't go down), and seemingly rapid drains where you end up with less than 10% left - but probably find in reality if you left it your battery would go on for ages at 0%.
Over time it learns, but best to wipe your stats after a long charge so it knows that 4200mV is 100%, and then don't charge your phone again until it physically runs out of juice so it knows what is 0%.
Another useful tip is to install the free BatteryLife widget from CurveFish from the market. That shows you the current voltage level as well as %age, so armed with the knowledge that full = approx 4200mV and empty = approx 3000mV you get an exact idea of how much you have left.
Mine does the same thing even draining/charging for few cycles

What did you do about it?
Anyone know what to do about this to an unrooted phone??
Or is this a defective piece and i should get a replacement??
Mines has done the same but I haven't had the chance to calibrate it yet to know if that'll help. It has helped on previous phones. I don't think your device is defective though.

How do you calibrate an unrooted device??
I think it calibrates itself after a few charge/discharge cycles. Always charge it a lot longer than when the green light comes on (because if the phone thinks the 100% level is a lot lower than it should be, that green light may come on early), and for the first couple of charges let it dry out rather than topping up.
And install that BatteryLife widget from CurveFish, then you can look at the voltage. 4200mV = full, 3000mv = empty, regardless of what your battery %age says. Mine currently says 51% and 3753mV.
Having the same problem here, restarted my phone afew times now and the battery % keeps going up, then dropping rapidly! :s

I'm having issues with my phone shutting off when the battery meter is low but not dead.The indicator will be yellow and still shut off. When I power it back on and plug it in, its completely dead .
is the phone innacurately reporting the battery percentage?
Sounds like the battery isn't conditioned correctly. There are apps in the market to help with that.
Look in battery configs battstats prob in /data/system and prob elsewhere
Sent from my HTC VLE_U using xda premium
Arent there other ways to condition the battery with an app? i heard like running the phone to empty and then fully charging? any advice?
The problem with running it empty is the battery will never fully discharge because the phone is reading the stats incorrectly.
can you recommend any specific app for this? do you have to be rooted?
You'd have to look at the requirements per app but I do believe you need root.
Your phone isn't going to report one thing, but "believe" a different thing because of bad battery stats. A Google employee has already debunked "conditioning" your battery by deleting battery stats; the phone uses it for reference only, not to make any decisions, especially when to shut down. Something is wrong with the battery itself, or your phone, not your stats.
Swyped, not typed, from my Digital Brick
It might be better over time. Had mine for two weeks now, and I had it run out on me three times. First time it shut down at about 13% left on the meter, second time around 8% and this last time at 2%. Good enough for me, but it's annoying if an untampered new phone doesn't report at least somewhat close to real battery-state.
I usually hook it on the charger at 15%-30% (approx 12-16 hours usage) in the evening, and sometimes have a few short charges (25-30 minutes) from the car-charger during the day.
I've never let mine get below 50% since I got it, but I just ran it into the ground with a terminal process ('yes && yes') and it went all the way to 0% and then powered off.
Previously I had Huawei with 4.0.3 and in night time (wifi disabled, sync disabled, no apps active) battery dropped about 3 points, but with Moto it's about 10 points.

The one of mine used last night more or less the same, around 10% with wifi, no apps running, no data conection, etc. I'm a little bit worried about it, i think it's too much battery drop :/

Previously I had Huawei with 4.0.3 and in night time (wifi disabled, sync disabled, no apps active) battery dropped about 3 points, but with Moto it's about 10 points.

I just go airplane mode and I had a 1% drop over 10 hours overnight.
download BetterBatteryStats or Wakelock Detector and check what eats your battery

I'm using Profile Scheduler, but since 4.3 it can't activate aeroplane mode, without rooting and I always forget switch it manually.
I always turn off my data and WiFi and my phone only drops about 4 to 6 percent overnight

It may have been related to Mediaserver, read - http://forum.xda-developers.com/showthread.php?t=2570854
I need SkyPe so can't unistall it but I disabled AD -s in SkyPe settings, and see does it help.
Edit: I removed latest SkyPe and installed older version and Mediaserver doesn't eat battery anymore.
It seems to do just fine at nighttime for me.
Nearly 0% drain after a night with airplane mode.

Tonight, in almos 6 hours my battery has dropped around 4% being in airplane mode. I have installed betterbatterystats and i cannot see anything strange
what used up the 4% that is not strange?
I unplugged my phone at around 3am because I rolled over and noticed the notification led blinking. I was at 100% and cleared the notification. Went back to sleep then got up around 5:30am and looked at my phone. I noticed my battery was down more than I expected so I checked the stats. I was down almost 20% in 2 hours 30 minutes. Android OS was at 60% usage with time on a 2 hours 20 minutes. I had sleep assist turned on during the night and I also keep wifi and data on. I've installed Wakelock Detector to see if it will be able to see what in Android OS is keeping my phone on.
Please take a look at

fyi. when you charge your phone, the battery starts discharging once the battery is FULL, NOT when the cable is unplugged. However, the battery % will not drop whilst the phone is plugged in,
Therefore, if you charge your phone fully but don't unplug it for hours, it 'may' appear to discharge faster than normal once you do unplug it. (basically the phone will over present it's true charge level).
If you unplug the phone as soon as its fully charged, however, it will appear to discharge more slowly...

think I must have missed the joke??, or are you wishing me 'Lots of Love' ?
you can test if for yourself if you don't believe me... It protects the battery..
it is very relevant for people who charge their phone over night. The Android battery stats will start the clock ticking from 9am when they unplug their phone, however the battery started discharging 6 hours erlier when he phone was fully charged at 3am... The % then drops much faster than expected as it races to it's 'true' level of charge. This could explain the differences people are seeing in some cases...

actually you are just partially right. the percentage only drops until reaching a trigger level, where it starts to charge again. also in my opinion when the phone is charged and left plugged in it uses the power directly and leaves the battery untouched

Hogwash.
Lithium batteries don't retain a memory.. You can charge them as often as you want... No matter what percentage your at. And if you leave it plugged in it will keep your battery fully charged with a trickle charge at 100...
I'm not sure what wives tales you've been reading.... But not everything on the Internet is true.... So you know.
I read something else around here lately where a guy was saying basically if you plug in at bedtime, you better wake up after a couple hours and unplug.... Or you'll damage your battery. Lol
Anyway.... Charge how ever you feel you need to.... To each their own. But I guarantee your battery will not drain quicker cause you left it charging all night.... That's simply ridiculous.
No offence.

its not hogwash, I think maybe you misunderstood me. I'm well aware lithium cells aren't memory cells. In fact, check my post history I posted as much in a thread of someone asking 'how best to first charge their moto G'. So if this is what you thought I meant, fairplay.
However,
Someone clarified above there is a 'threshold' level. however, these phones do not 'trickle charge' it's not a car battery. Charging at full amps when the battery is full would damage it, hence it stops charging, starts to discharge, then at some 'threshold level' will begin charging again, it does not trickle charge..
Also, as a matter of fact a friend of mine is an electrical engineer, does small Linux projects and some work on ARM architecture. I first heard about this behaviour when charging whilst on the XDA S2 forum. We tested the charge in the S2 1650mha battery ourselves and found we could get a variety of charge levels all shown as '100%' on the phone, just by when we unplugged the charger. I'm making an assumption this phone behaves the same, however why would it not?
So, all I would say to anyone on this forum. Just because someone has a lot of posts and thanks and 'knows his stuff' , This guy should take his own advice and not believe everything he reads on the internet...
