I got my Tilt 2 yesterday. I charged it to 100% before using it, then had it on all afternoon setting it up and adding programs. I charged it all night, but when I got up this morning the battery said 70%.
I went to the power settings and noticed there's an information tab that has status info since the last full charge. The status under Last full charge on my phone said "not applicable". I plugged it in at work this morning and waited a while to make sure the charging light turned from orange to green. It did and the battery power remaining was 100%. I left it charging another hour.
A little later I checked the information tab again. It still says Last full charge: Not applicable. HUH???
Aside from the Last full charge field, it also has stats for Standby time, Talk time and Device usage since last full charge. Since I apparently still haven't had a "last full charge" all the values are 0 on my phone.
Does anyone else have a date and time in that field on the information tab?
i got the same on my imagio.
When I first got my Tilt 2, I noticed that screen and thought "hey that's useful". It had the values all filled in properly. But when I went back later to check it, I saw "Not Applicable" just like you. It seems to be intermittent though, because I checked it just now and it has good data. I haven't noticed any correlated factors that predict whether the info will be there or not.

you should never leave your phone plugged into the charger after it has reached full capacity. you're basically draining the overall battery life of the phone, so it won't last as long off of a full charge.
did that to my old tilt before I found out about the overcharging thing, and had to use my warranty to get a new one since the phone would shut off by itself at 90%+ and turn back on again with >5% battery power left

I wasn't really sure that it was fully charged because of that stupid message about the last full charge not applicable. Thanks for the information. I didn't know that it was possible to ruin a battery by overcharging it.
@enisoc,
I thought it seemed like it would be a useful feature, too. Every single time I check power settings the values are null. It's interesting to know you've seen data there at least twice.
ETA: Now that I think about it, for the last two years I've plugged in my Tilt before going to bed and left it charging all night. Every morning it was 100% charged and I never noticed any adverse effects.

Maybe I've just been very lucky, but I have had a Sprint HTC Touch and before that a Samsung Blade (razr wannabe), each for two years. Every night for those four years, I plugged in my phone before going to bed and left it there. I have always had great battery life on both phones.
Specifically for the TP2, I have read that it stops charging at some point when it's done, and won't trickle even if you leave it plugged in. This has been reported by various people because they find that if they leave it plugged in for very long times, they'll end up with only about 95% battery, because after the first few hours it was no longer charging.
Perhaps less convincing, but also interesting, is the fact that (when it works) the "last full charge time" on my TP2 shows up as a couple hours after I went to bed, rather than the time when I unplugged it in the morning.
YMMV

oh wow really? that's interesting. that would be nice if it's really true. what I've been wanting is an app that allows the phone to make some sort of noise (i.e. an alarm sound) when it is fully charged. just to let it's owner know that it's finished and so it won't get overcharged. I think i'll go request it at development n hacking.
I am 100% sure that you cannot overcharge a TP2, in fact I would say any phone or device with a Lithium Polymer battery.
..........
it's true, once the TP2 hits 100% it stops charging the battery & the usage time will kick in.
Day 3 and still no data in the battery power information tab.
do a hard reset. mebbe itll work.
Since its very new, you got nothing to lose.
flip, do you have a TP2? If so, does that tab give you data all the time?
yes, its a Tmo TP2.
it worked on the Stock rom.
I have a custom rom now, and it works as well
once the green light comes on on the touch pro 2 u it stops charging, u cannot overrcharge it
Not only can you not overcharge the lithium Ion batteries it is actually better for them to be recharged as often as possible.
Menneisyys wrote a great article on it a while ago. This confirms what I have always been told.
http://forum.xda-developers.com/showthread.php?t=342162&highlight=battery+charging
Overcharging li-ion (and li-po) batteries results in catastrophic failure, a.k.a. explosion. Therefore, chargers for these battery chemistries stop charging when they're full.
Something is wrong with ne WM6.5 driver!
Yesterday my battery duration was about 24h (with 6.1 i charge it every 2-3 days!)!!
I fully charged at midnight and now, after 15h it says 90%... It's a little bit strange!
At midnight i could see battery stats.. Now it says "not applicable".
I used Dr SigStat and it says a temperature of 2,47°C!!! (in WM6.1 temperature was normal).
What's wrong??
Over the weekend I finally got some data on the information tab. Either Saturday or Sunday morning when I checked it gave some time around 5AM as the last full charge time. Now it's back to Not Applicable.
@D J Palmis,
I wonder if anyone knows the answer to the 6.5 battery dilemma. When I was using a cooked 6.5 ROM on my Tilt I was getting normal battery duration. My battery life on the Tilt 2 is comparable to my old Tilt.
i see this on my tilt2. battery info shows up, with idle/usage times for a short while after full charge (green) if i check after a few hours, it goes to n/a. looks like a driver bug to me.
Hi all,
I've been having issues with my phone lasting nowhere as long as my girlfriends identical one,
I installed Quick System Info on both phones, Killed all tasks.. Not only is my display duller than hers on the lowest setting using the power control widget but the voltage on my battery is 3737mV while hers is 4071mV..
Is this cause for concern?
Update, forgot to mention, this is from a full charge on both handsets.
Sounds like your battery is fu#ked!
There seems to be an issue with the way android reports the battery voltage. If I leave my phone on the charger until the light goes green and the indicator says 100%, the voltage will often report between 4.146v - 4.156v.
Upon unplugging the phone would drop to 99% and 4.125v almost immediately.
I noticed the other day that after leaving the battery on the charger overnight the voltage was reporting as 4.206v and I was able to use the phone for over 15min before it dropped to 99% from 100%.
Minimum voltage before your phone powers off is around 3.6v - 3.650v. So 3.737 is pretty close to the cut-off point. The OS is may report 100% charge but your battery is not holding charge.
I had a battery on a different device that was like this. The battery had collapsed. I could charge it for 24hrs and it would not make a difference. Within 30min of use or 1 phone call it would die.
Does your battery have any bugles, bumps or protrusions? This is often a sign of a collapsed battery.
Edit: Don't write when you're tired, silly things come out of your fingers! Soz!
have you tried to swap batteries between the two phones. That will exclude either your phone or the battery from being faulty.
Yes, after scratching my head for a few days I did eventualy come up with the genius idea of putting the battery from the other phone into my phone!! and after charging it up, set it down for an hour and then checked and the battery was on 98% !!
So it looks like there is something wrong with my battery, This morning I woke up and my phone had been charging for 7 hours and was fully charged, I looked at the battery meter and it said 100%, I turned the phone off then back on and checked again.. 90% ???? WTF ??? just from turning the phone off and on?
So after some time I've been battling with my battery life through the day. Few months back it was great, Id easily get a day no problem! Then I found I had a wakelock issue and had that fixed.
I now suddenly have almost multiple things going on at once but first a small back story.
Went to bed one night and had it plugged into the wall. Went to bed at 60% and woke up and my phone was down to 6%. I thought, well the usb port is bad or the cable. Took it into the sprint store, they of course say "it looks like its charging just fine, the light is coming on" (the light was on during the night too).
They checked the battery and they said it was bad. Im wanting to take it to another store and have them check, because either: they didnt want to replace me with a new phone or replace the usb port if thats bad.
1) Bad battery- in a matter of 30minutes (during my lunch break at work) my battery dropped from 63% to 14%- only used 3g for facebook and sent 2 text messages. And my phone is undervolted and underclocked
2) Possible bad usb port- I plug my phone in all day at work, and 90% of the time the screen is off. The % of the battery doesnt increase, but maybe decreases slightly (I have data and everything turned off while at work because I get no data signal).
3) wakelock- so suddenly I'm getting a huge percentage of system usage of 54% in my battery stats. A few months back it was maybe 1%? I flashed the .img that sets the wimax, PRI, NV, etc to what fixed the issue back then. Im just confused how this has come back now when I havent even updated anything related only my rom (MIUI 1.8.26).
So I've ordered 2 2000mah batteries off ebay- I wasnt going to pay $40 from a battery story across from the sprint store (as they didnt have any stock, only extended batteries).
If anyone has had a similar experience, or would know what is the culprit would love to get feedback. Hopefully I can get this fixed soon. Maybe just a trial and error.
Something really strange just happened. I checked my phone just now and the battery is at 98% and just maybe 30minutes earlier it shut off because of low battery
What I explained before about using my phone on my lunch break was only 2 hours ago and showed 16%.
I always wipe my battery states when I update my ROM or install a new kernal.

Don't wipe battery stats if you don't have a full battery, it'll keep your battery from charging fully.
It may be the battery, but since you're getting new batteries you'll know then. If you didn't get an external charger, I'd suggest doing so. That way you can guarantee that your extended batteries get a full charge, and you can switch out a dead battery with a fully charged one if you keep having problems. The usb port on the Evo is crappy anyway, but if the light comes on and stays on & you can transfer data through the usb port then I doubt that's the problem.
It could be hardware failure, but wait until you get a new battery and have properly calibrated to come to that conclusion.
In the meantime download Battery Monitor Widget, that should show you your true battery capacity even if the system will not. You don't have to use the widget, you can just open the app. Once you see that your battery is fully charged, calibrate your battery properly. Wipe battery stats at 100%, let it drain until it shuts off, charge to 100% without breaks, and you should be good to go.
Good luck!

Thanks for that!
I just bought a battery from BB to hold me over (50$ for a 1750mah battery?! )
when it charges to 100%, should I go into recovery, or use battery calibrator (app)?
Ill install that battery monitor too
BMW has the feature to wipe stats. I also recomend to look at the reports and judge when the battery is full by looking at mV. 4200mV is full charge. Then wipe stats FIRST, then unplug and run down completely, then recharge fully with out unplugging.

Ya just noticed BMW had that feature. Forgot I had a menu button. LOL!
This battery I got at BB is a "1750mah".
You know what I realized what might be the issue? Back a few weeks ago, I bought an extended battery to use to take videos at a concert. At that point I wiped the battery stats at 100% of the 2500mah or so battery..
I have a battery / charging problem on my Gnex. The problem is that the battery won’t charge more then 60 %, drains quick and then the phone shuts down at 0 % ( in about 2-3hrs of use) and wont restart until recharged.
At first, I tought it was the battery so I bought one OEM on ebay. It did the same thing so I returned it and went to Telus store to buy an OEM.
Same thing happened with the new OEM. I then bought an external wall battery charger and charged the 2 batteries I have. When I put the first one back in the phone it said 12%?
I tried the second one which is the new OEM and same thing, its showing 12%.
I did a little test, I had 4.2.2 so I unlocked the phone and rooted (no more warranty anyway) I flashed back the ROM to ICS. No change.
So what I did next is I used the phone until it shut down at 0% and restarted it on the bootloader screen and left it on, on the bootlooader screen.
Well the phone screen stayed on for more then 3 hours, so I know the battery is good because there is no way that a 0% battery could power the screen for 3 hours.
So after it shut down from the bootloader screen, I charged it again, in the phone, and it went right back to 60%, I did try to wipe batt stats from recovery mode and battery calibration apps but no luck.
Is there a way to disable the auto shut down on the phone? The battery meter if definitely showing wrong charge stats. Is the battery controller part of the USB board or the motherboard?
The only thing I did not try yet is a custom ROM and Kernel.
Any ideas?
Sounds like a hardware failure... It's obviously not the batteries

I found where the Power Management with Switch Mode Charger chip is, on the motherboard! I wonder if there is some ways to access and modify the values of this.

For what it's worth, the same thing is happening to me. Charges to 64%, and it acts like it's only got a 64% charge - runs out fast. And I also tried a replacement OEM battery with no difference. I'm not completely convinced this is a hardware problem - though I guess it could be. I'm still stock Gnex (with the 4.3 upgrade - and come to think of it, this started some time after that upgrade). I was hoping it was some kind of kernel problem that i could fix by switching to CM. Anybody have any luck with that?
The same thing is happening to my phone, although I'm lucky enough to have it charge to 73%. Only realized the problem when I bought a new OEM battery and it stopped charging at the same 73%. I have a friend who has the exact same phone and will give her both my batteries to charge and see the results (with her phone then once batteries are reinstalled in my phone).
Outside of replacing the motherboard, would anyone know if there could possibly be a software fix? Has this happened to any other phone? If so does anyone know the results?
Thanks,
Stefan
My gt s6312 has charging issue. It never charge over 67-69% in my phone. I checked the battery in other phone its ok.....please help.....

Sounds like a hardware failure in the phones' charging circuit. Since:
- no software change (ROM or Kernel) fixes it
- no battery change fixes it
Then it's obviously the charging circuit in the phone. Time to get a new phone!
Well I've confirmed for myself that it is my phone charging circuit that's giving me bad info on my battery charge. I installed both my batteries in a friends Gnex and both gave me 100% charge reading on my friends phone. I then re-installed both batteries in my phone and both came back with identical 13% charge reading. So to me this is obviously not a battery issue.
Since my previous post in July my phone has gotten progressively worst. So I have now come to the point where I either have to replace the phone's charging circuit or replace the phone all together. I would much rather do the first as any replacement phone via my carrier would require me to pay more monthly on my contract.
So would anyone know with certainty where the charging circuit is located in the Gnex? Is it on the main logic board or the USB charging board?
Thanks
Phone was at 98% battery. Did a reboot as I do every morning, and when it started up again it showed 91% battery. I know reboots don't take 7% battery, so what gives?
My Pixel 2 XL has been having some battery reporting issues, I noticed that when I took my phone off the charger it would lose 15% very quickly then stabilize. Rebooting would also cause a drop in indicated battery %. That's my guess. Investigating to see if it can be fixed by doing a full charge/discharge cycle.

I've also been seeing this issue! I will also be letting it do a full cycle today to see if it helps since it only started a few days ago.
My battery seems to be okay but my charge port when I place the cable in it doesn't feel like it fits snugly it almost has a slight wobble to it. Have you guys been noticing that as well?
I've actually been experiencing this as well for a week, I called up Verizon and they shipped me a new phone. So far no charge issue anymore on this one.
I have experienced this too
Tested this again this morning. Had the phone charging overnight.
Unplugged it, it showed 100% battery.
Immediately rebooted, and it dropped to 96%.
With a lot of phones, battery stats reset on reboot. Also- the percentage isn't a perfect science. Just let the phone do its thing. Run the battery down and recharge it. No need to reboot the thing every day.
The battery has been great for me. I use my phone extensively throughout the day, maybe 3-5 hours on time, I always make a day of use without needing to plug in. I had a light use day yesterday, and had 30% left @ 11pm, after pulling off charge the night before @ 11:30pm.
Pleased to announce that (in my case at least) doing a full cycle reset the fuel gauge and it is now working properly. I've never seen a device come with a miscalibrated fuel gauge from the factory, so that was odd. I usually keep my li-ion powered devices between 80% and 30% SoC(state of charge) to reduce cell degradation so we'll see if the fuel gauge becomes uncalibrated over time (which would be somewhat unusual) or if this was simply a software fluke.
Yea I have noticed that in my case, my phone says 100% on the charger so I will restart the phone while still plugged up and once it's booted back up it says 98% so it lost 2% while hooked up to the charger lol. Doesn't seem to affect the battery life. I'm still able to get 5 hrs of screen on time but I will try to kill it completely and charge fully today and see if it fixes it.
This morning I didn't do the restart and didn't use the phone or even turn my screen on and within fifteen minutes I turned it on to 98 % remaining.
