I don't know if I am the only one seeing this, but when I had Eclair, I had crap battery life, to the tune of 10 hours or so. (Granted this may not be crap for Nexus One but it is crap based off past phones I have had.) I installed FRF85B last night and discovered some weird glitches.
First off, when it was in my car dock, it wasn't charging yet the battery life kept dropping, I powered off the device, and powered it back on 10 minutes later (still in the dock) and no change stayed at 91%, still wouldn't charge. I then powered it off, took it out of the dock, plugged in the car charger cable directly and powered on my N1, when it turned on, it said I had 100% battery life. I then plugged it back into the car dock, and voila it started charging.
Secondly, originally when I had unplugged my N1 this morning I used it for about an hour at 5AM and it dropped 2% I plugged it back in to top it off expecting the same crap battery life from Eclair, yet so far, my phone has been fully topped off (from the car dock) for the past 40 minutes and I've made about 20 minutes of phone calls on it, yet it still is reporting 100%. So either Froyo can't properly report battery life, or it has the potential to have absurd battery life. Anyone else experiencing anything like this?
First off - you still didn't search this forum, so you're still thinking that an overcharging protection that doesn't allow you to charge unless you drop below 91%, is a quirk. It's not.
Second, wiping battery stats and making battery calibration procedure ONCE will give you a good starting point to measure something.

The quirk isn't that it wouldn't let me charge that way, the issue was, my battery reported 91% yet when I rebooted the device with the charger directly plugged into it, it immediately showed 100%. So pretty much over the course of 30 seconds I gained 9% battery life.
I wiped my device to factory settings before upgrading to Froyo, and after as well, since my device is not rooted, my understanding is I cannot wipe my battery calibration log.
I did drain my battery fully after upgrading to froyo last night and did a full charge as well.
What you're describing looks like the statistics of the battery is "lying" a bit. I believe it can be thrown a bit off by trying to charge it when it's in 91-100% range, but I don't know the exact way it works, so I can't say much about it.
Indeed, if you're not rooted, wiping battery stats is not an option. Several times of full charge and long discharge (you don't need to go below 20%, to prevent harming the battery) are helpful in correcting the statistics.
If you get a chance to try, please repeat this again (having the phone at >90%, turning it off, plugging it into the charger and turning it back on). If it shows "Charged" again - it might be a bug worth reporting.

I'll have to try it again tomorrow morning, first see if it happens under the same circumstances and go from there. One thing I do remember is the widget I was using "Battery Left" reported that at 91% I had 4100 mAh left in it, which was interesting, and when it went back to 100% it had 4120 mAh which makes me think the OS wasn't actually reading the voltage and thought it was just draining the battery instead.
EDIT: Just realised I had my wall charger with me, battery was at 90% figured I would try, real quick to attempt to replicate the problem, I was unable to, with a direct battery connection, but it could be due to a voltage issue or be related to why plugging it in directly to the car charger resolved the issue. My gut feeling is, it has to do with the dock itself and the pins it uses.
my battery often is charging and it hits 93% and immediately jumps right to 100%. it skips the last 7% or so. i think what is happening is you just finally experienced this issue, which many of us have already posted about in battery threads, but it just happens to coincide with froyo so you are thinking its new and related. the nexus ever once in a while battery meter just gets thrown off and will jump up to 100% because it really was full, just had to catch up the meter. you really should pay attention to the voltage more than percentage, using battery life widget. i know my battery is fully charged at 4.172 volts. and sometimes it hits that but still only shows 94%, so it adjusts itself in one fell swoop.
The issue is I did an extra full charge about an hour ago so I can make it till midnight and it went through all the numbers from 89-100 with no issue

Addendum: Also it seems to be voltage is not that good of a decider of how much my charge is. Before Froyo, until I dropped below 94% I was always above 4 Volts, now I drop below 4 Volts at 96%.
So this morning I was able to replicate the problem, only it was outside of the car dock, I was able to get this problem to reoccur with the wall charger. I unplugged it from power, used it a little bit and then topped it off for the day, it was at 96%. I saw the green light go on, and thought nothing of it, 20 minutes later I went back to it and it was still at 96% and showed that the battery was fully charged.
I checked the Battery Left widget and it was saying the battery was fully charged even though it said 96% left also. I did make a crappy video uploaded to youtube from my backflip to show as well what I am talking about.
AFAIK, The green LED will light when you're anywhere above 90%. It's not a function of charge being complete. Check it.
Also, if you plugged it in with 96% - this is the behavior to be expected, since the phone won't start charging unless it has below 90% to begin with, and it'll show "Charged" - because it's not charging (to prevent overcharge).
Again, fail to see any problem in what you're describing.

Yet my phone has always been able to charge when above 90% before froyo. This behavior is new to froyo for me at least.

It means that you've never paid attention to that until now. It's working this way since the phone was out (with stock Eclair) and if I'm not mistaken - it's not controlled by OS at all.
I did pay attention to such actually because of the fact that I had been getting piss poor battery life. This has never happened before. In the morning I would use the device a little then top it off because I noticed that works give better battery life.

Well, you had a buggy phone that has now corrected itself. Welcome to the way it was supposed to work from the beginning.
Topping off the battery at 90%+ contributes to battery degradation - heating from overcharging. So you were actually damaging your battery.
Hello. 1st post & glad to be here. Just picked up a new Motorola X for Sprint & want to ask a question or 2 & share my experience.
I purchased the phone yesterday morning & got it all set up & then started to use it. Without charging it & using the phone I went from about 50% to 20% for the day. Not bad but when I was on the phone I got an alert that my battery was low. It went from 20% to 3%. Later ticked down to 0%. I chalked this up to being a new battery with not a full charge on it yet. So I charged it up & revisited the phone this morning. While still on the charger I notice the battery indicator in the top right still showed a "lightning bolt" but the lock screen advised "charged." - So I took it off and My battery would go down from normal usage but after not using it for maybe half an hour it would go back up 3%. (I.E. - 88%, not use the phone for 30 mins. Recheck & its at 92%) Went into Sprint & they advised probably a battery issue and offered another device. Sure sounds good to me...whatever you think will help.
Fast forward to this morning to when I got the new device. He went to start the phone to activate it & it said it was dead. 0%. Plugged it in and after a few mins the phone booted up and showed around 50%. He advised if its been sitting a while it just needs a charge to get it going. So I get home, and start setting it up and about 45% the phone says low battery and shuts down. I'm thinking this is just the way this battery starts off I guess? So I charge it up and it starts charging at 50%. Leave it on the charger for a good 2+ hours. Same battery indicator as phone #1. "lightning bolt" but lock screen saying charged. -- Any insight on to why this is. I have searched around & have not gotten anything close to this sort of issue?
Note: My battery does do fine when actually using the phone like normal after its charged up. All the battery stats are acceptable & well within normality. This 2nd phone shows to be fine so far with the battery % not fluctuation. :Crosses fingers: Is this "normal" for the Moto X to start? What are the odds that 2 different Moto X's have the same issue?
Thanks for your help.

Hmm... not sure. Typically they advise you to fully charge before activating, which may have to do with the software reading the battery correctly. But I didn't have this issue at all with mine. Perfection from the very start. Actually the best and most perfect phone I've owned in the 17 years I've been with Sprint.
There is no such thing as "battery memory" with Li-ion or polymer batteries. I'm going to say that however rare it may be, both devices suffered from the same bug or hardware issue.

This is correct, it appears you got two bad ones in a row.
Sent from my all black Moto X
I've had my moto x about a month.. and recently noticed the battery drain going downhill.. while using it I've noticed losing a percent about every 2.3 minutes verse 3+ minutes... works out to a loss of an hour or so from full charge. GPS off and brightness set to lowest setting, haven't changed anything that would cause the drain to increase, but I leave it on a charger when using it as a hotspot.. and the charger is my nexus 7 charger not the moto charger.. but this never caused battery problems with my razr m.
More things installed and running I bet is all. You're talking a small difference really.
But without screen shots from gsam or something useful (so not stock battery screen ).... You'll get only wild guesses from people.
So, this is a strange issue. When my phone dies, it will die when it says I have 5% of battery. Sometimes, it will die at a reported 4% instead. This randomly started one day. I got the 5% remaining notification, and suddenly, my phone shut down. Ever since, I can't get below 4%. I've tried to turn the phone on, but it acts like it is dead.
I'm not sure if it's just reporting the wrong percentage, or if it's actually dying early. I've tried flashing different ROMs, wiping everything, and no change. I've also used Battery Calibration to delete battery stats, with no change. I've had issues with other phones dying a little early, but battery calibration always fixed it, so I'm at a loss. Has anyone else experienced this? Is there anything I can try to fix it?
Definitely have this issue too. Dies at 4% strangely enough. Thought it suppose to croak at 0% lol.

Its just not reporting the percentage properly. MIne does it too.
The phone will shut off when the *voltage* drops below a certain threshold, regardless of what the actual "percent left" indicates.

Yep indeed.
There used to be tricks to get the % to show correctly but they weren't entirely good.

In theory, the percentage display is supposed to calibrate automatically to the voltages... however it should be noted that the battery's *minimum* voltage does need to be programmed in at some point in the process, since the shutoff voltage can NEVER vary. Most likely, the problem of shutting off at 4-5% is a matter of "feel good" battery levels, much like some lingerie stores will label items with the "next size down" or "next cupsize up" to make women feel smaller and bigger in the areas they want. It basically bumps the full scale percentage display by an average of 2.5% UP, which can lead some less observant users to viewing that as a slightly improved battery life. Most people will plug in before it hits 5%, so won't even notice this.
So, basically, that's just how it is? I've never had a phone that was so off. And I still don't understand why it went down to 0% or 1% the first few weeks I had it. It's not an issue, it's just strange.
mine shuts down at 3% every time

my nexus 5 died after going to below 1%. every time. i have a hard time believing thats just how it is in this case. chalk it up to yet another lollipop bug i would say...

My n5 shuts down at 1% every time on lollipop. Chalk it up as an n6 "bug" if there's chalking to be done.
I also have this issue and posted a similar thread about it a couple weeks ago. Given that any other device I've owned has been able to consistently reach 1% before shutting off, I think this is either a Lollipop bug or specific to Zthe Nexus 6.
I'm going to test it with my Nexus 9 and ask a buddy about his Moto X 2014 and report back.
Mine died at 9% sigh...

That's the funny thing though, because it never did that. It just aligned shut off with 0%
Happened to me once so far, hit 4% and it shut down unexpectedly. I chalked it up to the kernel at the time, as I had flashed a new one the night before.
Maybe it's intentional?
The Nexus 4 could sometimes be a real pain to reboot if you let it go completely dead. I suppose it's possible Motorola/Google are preventing complete depletion of the battery.

Complete depletion of the battery would literally lead to an explosion upon recharge. That's why all lithium based batteries have an additional 10 - 20% below the battery chip shutdown voltage.
Also a phone that shuts down at 5% is more likely to automatically shut down than one that shuts down at 0% as its a little more unpredictable.
now i have the opposite problem. my phone keeps charging after it hits 100%. i use current widget, and watch it when im charging. and current keeps coming in after its at 100%. it will depend, but sometimes it could still be charging for a half an hour after it hits 100%. but then again, it could stay at 100% for 30-60 minutes after i start using the phone on battery again :silly:

I remember the battery calibration trick on Tue original HTC desire. Turn the phone off and charge to 100 then reboot and charge again. It got the % out of whack and gave a false perception that the battery lasted longer as it stayed at 100 for much longer than it should do.
Hi!
I just recently bought a Moto X 2014 (Second gen) and for some reason, it turns off when it reaches 10% battery left. I got scared and I thought it was a problem with the battery itself. The issue is that when I charge the phone, it starts from 0% battery, and then increasing to 1%, 2%, etc. At 90% usage, it then goes off and ignores the remaining 10%. That’s why I can’t determine if it’s a battery calibration issue or a hardware Issue.
Thanks beforehand
My girlfriend and I have the exact same issue. We have the Moto X pure editions, mine is rooted with TWRP, and hers is totally stock. I haven't had much luck resolving this issue either.
Same problem here. My wife has a 2nd gen Moto X as well (mine is pure, hers is AT&T). This started about 2-3 week s ago I think and they both started doing it at the same time. I'm hoping its software, but who knows.
I don't know if my issue is exactly the same, but in the same vein. My phone was on the charger and was at 96% at 10pm. Woke up at 2am to feed the baby and unplugged it from charger. By the time I got done taking care of the baby, I picked up the phone and the battery was at 60% and was very hot to the touch. The usage monitor said that the display was the big user but how can that be when it was off!

Maybe you had left some apps running
They keep running in background untill you properly shut them down.
Running apps will always wakeup your cpu, screen even if youre not using them.

I had this problem previously, but now my phone will shutdown if below 1%. I dont know what I've done, maybe the battery calibrating it self.
